- the present invention proposes various solutions for solving this problem.
- Each of the solutions described below is suitable in itself to contribute to solving the problem mentioned and thus represents a separate solution to the problem.
- the solutions described and their embodiments can be combined with each other in a particularly advantageous manner.
- Embodiments can thus have features that are disclosed in connection with other solutions or other embodiments. Furthermore, the described solutions and their embodiments can have features that are explained above in connection with generic systems.
- the invention proposes a system that has several mounting bodies and at least one support rail with a U-shaped cross-section.
- the system is designed to realize a lamp that is elongated in the longitudinal direction.
- the mounting body is to be arranged and fastened to the support rail.
- the support rail and the mounting bodies arranged thereon together enclose an interior in which supply lines and in particular at least one functional element of the lamp are arranged.
- a contact device and/or an operating device can be arranged on the side of at least one of the mounting bodies facing the interior and fixed to this mounting body.
- a lighting module comprising an LED board can be arranged on the side of the mounting body facing away from the interior, so that the LEDs emit light from this side of the mounting body in a proper operating state of the luminaire in the direction away from the interior.
- the support rail has a support rail base extending in a transverse direction between two support rail side walls and an open side opposite the support rail base in a vertical direction, the U-shaped cross section of the support rail being formed by the support rail base and the support rail side walls. Accordingly, the support rail side walls extend away from the support rail base in the vertical direction.
- the mounting bodies are arranged one behind the other in the longitudinal direction on the open side of the support rail and are fixed to the support rail and, together with the support rail, enclose an interior space.
- the operating state is generally defined by a specific arrangement of the components of the system.
- the system is in the operating state when the luminaire is created.
- the system comprises a sealing device which, in the operating state, is arranged between two mounting bodies adjacent in the longitudinal direction and which has two sealing surfaces. Each of these two sealing surfaces is assigned to exactly one of the two mounting bodies adjacent in the longitudinal direction. The two sealing surfaces are thus each assigned to a different one of the two mounting bodies.
- the two sealing surfaces are preferably spaced apart from one another in the longitudinal direction.
- the two sealing surfaces preferably each form a longitudinal side of the sealing device.
- the sealing surfaces each have a partial surface, the partial surfaces of the sealing surfaces facing away from one another along the longitudinal direction and in particular forming at least one section of one longitudinal end of the sealing device.
- the sealing contact of the respective sealing section on the sealing surface assigned to it prevents dust and/or water from entering the interior from the outside between the sealing section and the sealing surface during operation.
- each of the support rail side walls has a holding section on its side facing the opposite support rail side wall, wherein in the operating state the sealing device is fixed to the holding sections while defining a transverse relative position of the support rail side walls to one another at the level of their holding sections.
- the holding sections are thus provided on the two sides of the two support rail side walls that are opposite one another in the transverse direction, and the sealing device is designed to correspond to the holding sections of the two support rail side walls.
- the sealing device thus has a holding device corresponding to the holding sections of the two support rail side walls, and in the operating state the holding device and holding sections engage with each other in such a way that the interlocking of the holding device and holding sections determines the transverse relative position of the holding sections of the support rail side walls to each other and thus the transverse relative position of the support rail side walls at the level of the engagement of the holding device in the holding sections to each other.
- the design of the sealing device according to the invention, corresponding to the support rail thus effectively prevents the support rail from bending up, i.e.
- support rails of a system according to the invention are subjected to considerable forces when used as intended, for example in the course of loading a mounting body attached to the support rail and/or in the course of loading a suspension of the support rail, for example when the support rail is suspended from a ceiling and in particular the ceiling experiences movement.
- the formation of slots and thus the threat of leaks can be effectively prevented by providing the corresponding sealing device, without costly and time-consuming measures being required when implementing the support rail or when assembling the mounting body or the sealing device.
- the support rail is made from sheet metal by means of forming.
- the holding sections are spaced apart from the support rail base in the vertical direction by at least 70% of a vertical height of the support rail, i.e. the entire extension of the support rail in the vertical direction.

- the support rail has a vertical height of at least 5 cm, in particular at least 7 cm.
- the sealing device has the sealing surfaces explained and is arranged between two mounting bodies adjacent in the longitudinal direction, as explained above, with a sealing section being provided on each of the adjacent mounting bodies, via which it rests on the sealing surface of the sealing device assigned to it in the operating state.
- the sealing device is preferably fixed to the holding sections by determining the transverse relative position of the support rail side walls to one another at the height of their holding sections or has the relevant advantageous features described here, whereby to implement this solution, for example, the sealing device can only comprise the web element explained below, but not the fixing element.
- This inventive solution can of course also have features that are explained here in connection with sealing surfaces or the sealing device as a whole.
- the sealing device engages behind each of the holding sections, determining their transverse relative position to one another. By engaging behind, the sealing device thus provides stops for the holding sections, whereby the provision of these stops prevents the holding sections from moving away from one another along the transverse direction.
- the transverse relative position of the holding sections and thus of the support rail side walls to one another at the level of their holding sections is fixed at least in such a way that a maximum transverse distance between the holding sections is fixed by the fixing.
- both a maximum and a minimum transverse distance of the holding sections is fixed by fixing the sealing device to the holding sections, so that the holding sections cannot move towards or away from one another with respect to the transverse direction due to the fixing when the system is used as intended.
- the support rail side walls each have a recess, wherein the holding sections of the support rail side walls are each formed at least in sections by a transverse limitation of the recess, wherein the sealing device has a fixing region in each of its two transverse end regions, wherein in the operating state each of the fixing areas is arranged in one of the recesses assigned to it. Since the holding sections are formed at least in sections by a transverse limitation of the respective recess, the holding sections directly border on the recess.
- the recess is a recess running perpendicular to the transverse direction, so that by arranging the fixing areas in the recesses the transverse relative position of the support rail side walls can be determined particularly effectively.
- the fixing areas each rest on a section of the support rail side walls which delimits the recess on its side facing the opposite side wall along the transverse direction, so that this rest prevents the holding sections or the support rail side walls from moving apart at the level of the holding sections, relative to the transverse direction.
- the fixing areas can form the holding device explained above or at least be encompassed by it.
- the holding sections can each be formed by a deformation of the support rail side walls, through which the respective recess is also formed.
- the sealing device in the operating state rests on both a vertical top side and a vertical bottom side of the holding sections, each with a contact area.
- the sealing device thus comprises four contact areas, two of which are assigned to exactly one of the holding sections, with one of the two contact areas assigned to the respective holding section resting on the top side and one on the bottom side of the holding section.
- the contact areas on the top and bottom side of both holding sections enable particularly good stabilization and, in particular, sealing.
- the contact areas can be included in the holding device explained above.
- the contact areas are particularly preferably arranged between fixing areas of the sealing device in relation to the transverse direction.
- the fixing areas can be as explained above be designed.
- the sealing device with the fixing areas engages behind the holding sections in the operating state, preventing the holding sections of the support rail side walls from moving apart in the transverse direction.
- the contact areas can contribute particularly advantageously to sealing.
- the sealing device has spring areas with which it rests on the top of the holding sections in the operating state and presses against them with a spring force.
- each of the spring areas forms one of the contact areas.
- the spring force preferably has at least one directional component along the vertical direction, so that the respective spring area preferably presses against the respective holding section from above due to the spring force along the vertical direction.
- the spring areas are generally preferably designed to be spring-elastic in the vertical direction.
- the spring areas are designed to be spring-elastic in both the vertical and transverse directions. This makes it particularly easy to implement the operating state, i.e. a proper arrangement of the components of the system relative to one another, and, moreover, sealing can be particularly advantageously ensured.
- the sealing device is supported with a section on the support rail so that the spring force can be exerted.
- the sealing device has counter areas with which it rests on the underside of the holding sections in the operating state and presses against them.
- each of the counter areas forms one of the contact areas explained above.
- one of the counter areas together with one of the spring areas forms a pair of contact areas, wherein the spring area forms the contact area adjacent to the top and the counter area forms the contact area adjacent to the bottom and thus the holding section, which is assigned to this pair of spring region and counter region, is held pressed between the counter region and the spring region.
- the spring regions particularly preferably have a significantly greater vertical extent than the counter regions. Due to the large vertical extent of the spring regions, their spring elasticity can be provided particularly simply and advantageously.
- the spring regions are preferably designed as a spring arm made of a plastic.
- the counter regions are particularly preferably designed to be stiffer in the vertical direction than the spring regions, and the spring regions are particularly preferably elastic in the vertical direction, whereas the counter regions are rigid in the vertical direction.
- Spring regions and counter regions are preferably formed by a single, self-contained component of the sealing device, this component having a greater material thickness within the counter regions than within the spring regions.
- the counter regions particularly preferably press against the holding sections assigned to them in both the vertical direction and the transverse direction.
- the counter areas, with respect to the transverse direction only rest on the holding sections at those points that are closer to the transverse center of the support rail than those points on the holding sections where the fixing areas of the sealing device rest.
- the spring areas, with respect to the transverse direction only rest on the holding sections at those points that are closer to the transverse center of the support rail than those points on the holding sections where the fixing areas of the sealing device rest.
- each of the holding sections has a contact area that is, with respect to the Transverse direction is arranged next to the recess assigned to the respective holding section and is closer to the transverse center of the support rail than the recess, wherein the spring regions and/or counter regions are supported on this contact region or rest on this contact region, in particular exclusively on this contact region.
- the sealing device has sealing webs, each of the sealing webs being assigned to one of the counter areas and spaced apart from it. While the counter area is intended to press against the underside of one of the holding sections of the support rail in the operating state and thus functionally contributes to the fastening of the sealing device to the support rail, in particular in the explained interaction with the respectively assigned spring area, the sealing web serves to provide a barrier that counteracts the penetration of dust from an environment into the interior. By spaced apart the sealing web from the counter area, the sealing web and counter area can fulfill their respective functions particularly advantageously.
- the counter area and sealing web are preferably formed integrally from a single component that is part of the sealing device or forms it.
- the component can be the web element explained here.
- the counter area and sealing web preferably run over the same longitudinal section.
- the sealing web preferably extends over at least 70%, in particular at least 90%, in particular at least 100% of the longitudinal extension length of the counter area, in particular on both long sides of the counter area beyond the latter.
- one of the holding sections of the support rail is arranged at least in sections between one of the counter areas and the sealing web assigned to it.
- each sealing web preferably extends vertically above the counter-area assigned to it, at least in sections. This can particularly advantageously ensure that the counter-area presses vertically against the holding section from below, but the sealing web above it at least contributes to providing a dust barrier.
- the sealing surfaces of the sealing device each comprise at least one partial surface, in particular several partial surfaces.
- the sealing surfaces can thus be formed by one of the partial surfaces described below, in another embodiment, the sealing surfaces are formed by a plurality of partial surfaces, at least some of which can be designed as explained below.
- the sealing surfaces are preferably formed by the partial surfaces explained below.
- the sealing surfaces each comprise a partial surface running in the longitudinal direction, wherein the sealing section provided on each of the adjacent mounting bodies rests sealingly on one of these partial surfaces assigned to it. As explained above, exactly one of the sealing surfaces is assigned to each of the adjacent mounting bodies.
- the sealing section By the sealing section provided on the respective mounting body resting on the partial surface that runs in the longitudinal direction, the sealing section can move in the longitudinal direction relative to the sealing device without this impairing the sealing system, since the sealing section can move sealingly against the partial surface along the longitudinal extent of the said partial surface.
- a longitudinal clearance is provided between each of the sealing sections and the sealing device in such a way that the two mounting bodies with the sealing sections provided on them can move in relation to each other in the longitudinal direction, while the sealing device and thus its sealing surface remain unchanged in one position and the sealing sections provided on both mounting bodies are continuously at the respective associated partial surface in a sealing manner.
- the sealing device is preferably fixed in a fixed position relative to the support rail in relation to the longitudinal direction, whereas the adjacent mounting bodies can move in the longitudinal direction relative to the support rail.
- This makes it possible to take into account, on the one hand, a thermal expansion-related longitudinal movement behavior of the mounting bodies relative to the support rail and, on the other hand, a particularly simple assembly of the mounting bodies on the support rail.
- a seal between the two adjacent mounting bodies by means of the sealing device is ensured over a certain range of movement of the mounting bodies in relation to the longitudinal direction.
- each of the two partial surfaces running in the longitudinal direction extends over at least 5 mm, in particular at least 10 mm along the longitudinal direction.
- each of the two partial surfaces runs at an angle between 70° and 110°, in particular between 80° and 100°, in particular perpendicular to the vertical direction.
- the mounting bodies, the sealing sections provided on them, the support rail and the sealing device are designed to correspond to one another in such a way that, over a range of movement, in relation to the longitudinal direction, of at least 2 mm, in particular at least 3 mm, in particular at least 5 mm, in particular at least 7 mm, in particular at least 10 mm of the mounting bodies, in the operating state, a sealing contact of the sealing section on the said partial surface running in the longitudinal direction is always ensured.
- the said partial surface running in the longitudinal direction extends uninterruptedly over the entire transverse distance of the holding sections of the support rail over its entire longitudinal extension length.
- the sealing surfaces of the sealing device each have a partial surface running in the vertical direction, wherein these partial surfaces running in the vertical direction each run over the same vertical extension area and are vertically spaced from the support rail base.
- the partial surfaces running in the vertical direction preferably lie directly on the sealing section of the respective mounting body or are spaced from it by less than 3 mm, in particular less than 2 mm, in particular less than 1 mm.
- the mounting bodies By both partial surfaces running in the vertical direction extending over the same vertical extension area, the mounting bodies can be arranged at the same vertical height on the partial surfaces assigned to them, so that, for example, the mounting bodies can press against the respective partial surfaces when they lie directly against the partial surfaces and can thus press against each other indirectly via the sealing device.
- the partial surfaces running in the vertical direction are spaced from the support rail base by at least 70% of the vertical height of the support rail, i.e. its entire vertical extent. This allows a sufficiently large interior space to be provided between the support rail base and the partial surfaces.
- these partial surfaces running in the longitudinal direction are preferably also spaced from the support rail base by at least 70% of the vertical height of the support rail.
- the sealing device is preferably spaced from the support rail base by at least 70% of the entire vertical extension of the support rail, i.e. its vertical height, over at least 70%, in particular at least 80%, of its transverse extension in the operating state. The focus here is on the entire transverse extension of the sealing device.
- the sealing device over at least 90% of the transverse length of the distance between the holding sections in the operating state, continuously spaced from the support rail base by at least 70% of the vertical height of the support rail.
- the sealing device has a web element and a fixing element, wherein the web element forms at least a predominant part of at least one partial surface of each of the sealing surfaces. Particularly preferably, the web element forms both sealing surfaces completely.
- the fixing element preferably forms the fixing areas of the sealing device explained above and/or, in the operating state, engages behind the holding sections of the support rail side walls, determining their transverse relative position to one another, as explained above.
- the sealing device has, on the one hand, the web element, which forms at least a predominant part of a partial surface of the respective sealing surfaces or a predominant part of the two sealing surfaces or the two sealing surfaces, and, on the other hand, a fixing element, which serves to determine the transverse relative position of the holding sections and thus of the support rail side walls at the level of the holding sections, each of the two elements can be specifically designed for its purpose.
- the web element and the fixing element are manufactured independently of one another and thus designed as separately manufactured components.
- the fixing element is particularly preferably detachable from the web element to implement the operating state. Starting from the operating state, the fixing element is particularly preferably detachable from the web element without changing the relative position of the web element relative to the support rail.
- the web element is particularly preferably first fixable to the support rail independently of the fixing element to implement the operating state, and then the fixing element is fixable to the support rail and is fixable relative to the web element at least by means of the support rail to implement the operating state.
- the fixing element and web element are each made as a plastic part, in particular as an injection-molded part.
- the fixing element and web element are made from the same material.
- the Fixing element made of a harder material than the web element.
- the web element is designed to be elastic, whereas the fixing element is designed to be rigid.
- the fixing element is designed in the manner of a trough that is open vertically upwards or downwards with fixing areas that protrude vertically downwards. This allows the fixing element to be designed to be particularly material-saving and simple, while at the same time being sufficiently robust.
- the fixing areas can be provided on the two transverse sides of the trough.
- the sealing device can only have the web element, which in this case has all the sealing surfaces of the sealing device.
- the fixing element is then only preferably provided as a further advantageous measure.
- the web element can have the advantageous properties described here with reference to the web element or with reference to the sealing device, for example in connection with contact areas, spring areas, counter areas, sealing or partial surfaces.
- the system comprises several pairs of longitudinally adjacent mounting bodies, wherein the pairs are divided into two types of pairs: In the first type of pair, a sealing device is arranged between the two adjacent mounting bodies of the pair, which not only has the sealing surfaces explained, but is also fixed in the operating state to the holding sections, determining the transverse relative position of the support rail side walls to one another at the level of their holding sections.
- the sealing device which is arranged between the adjacent mounting bodies of such a first type of pair on adjacent mounting bodies, comprises a web element and a fixing element.
- the sealing device arranged between the adjacent mounting bodies of the pair has the sealing surfaces explained without being designed to be fixed to the holding sections in the operating state by determining the transverse relative position of the support rail side walls to be fixed to each other at the height of their holding sections.
- the sealing device arranged between the adjacent mounting bodies of the second type of pair has only the web element explained, but not the fixing element.
- two mounting bodies adjacent in the longitudinal direction are thus always sealed to one another via a sealing system on the sealing surface of the sealing device arranged between them or the web element arranged between them, whereas only some of the sealing devices determine the transverse relative position of the support rail side walls in the operating state. This can reduce the costs of producing lights and, in addition, it can still adequately prevent the support rail side walls from bending open for many applications.

- the contact sections of the sealing devices that are assigned to the two adjacent mounting bodies are spaced apart from one another along the longitudinal direction by a longitudinal spacing range, wherein the sealing device, in particular at least the fixing element of the sealing device, runs within the longitudinal spacing range.
- the sealing device is enclosed by the spring sections of the two sealing devices on its longitudinal sides, so that the spring section of a first of the sealing devices is arranged at a first longitudinal end of the sealing device and the spring section of a second of the sealing devices is arranged at the second longitudinal end of the sealing device.
- the sealing wall sections each extend within the same longitudinal extension section as the sealing device.
- the sealing wall sections of the two sealing devices are spaced apart from one another along the longitudinal direction, wherein the sealing device extends between the sealing wall sections of the two sealing devices in the operating state and furthermore overlaps with each of the sealing wall sections of the two sealing devices along the longitudinal directions.
- the sealing wall sections of each sealing device each extend, relative to the longitudinal direction, between the sealing web of the sealing device and the contact section of the sealing device from which they are formed.
- a sealing device is provided on at least one of the mounting bodies on its two long sides.
- the mounting body In the operating state, the mounting body is Overhang sections of the two sealing devices are fixed to the support rail in relation to the vertical direction.
- the sealing devices provided on the two long sides of the mounting body thus contribute to fixing the mounting body to the support rail.
- At least one of the mounting bodies is held on the support rail by at least two actuatable retaining springs and, in addition, by at least one non-actuatable retaining spring, in particular several non-actuatable retaining springs.
- actuatable retaining springs that have elastically deflectable retaining arms that each engage behind a holding section of the support rail in the operating state, whereby the mounting body is held on the support rail, is well known in the prior art.
- At least one actuating element is usually provided on such actuatable retaining springs, by means of which at least one of the retaining arms can be deflected elastically along the transverse direction starting from the operating state, after which the mounting body can be easily removed from the support rail along the vertical direction.
- Such an actuatable retaining spring can, for example, be designed as a retaining spring according to the invention, as explained here. Furthermore, it is advantageous to provide non-actuatable retaining springs in addition to such actuatable retaining springs, which are designed, for example, as sheet metal springs.
- non-actuable retaining springs can, for example, provide a lower holding force than actuable retaining springs, but the provision of such non-actuable retaining springs is sensible because the actuation of the actuable retaining springs requires a corresponding actuation action and the non-actuable retaining springs can, in addition to the actuable retaining springs, provide at least a certain additional holding force, which ensures that a mounting body is held as close as possible to the support rail over its entire longitudinal extension, which in particular serves to improve sealing.
- the invention proposes that at least one of the non-actuable retaining springs, when only one non-actuable Retaining spring, this non-actuable retaining spring, is formed by a sealing device as explained here.
- the sealing device with its overhang section thus preferably fulfills the special purpose of ensuring further fixation of the mounting body relative to the support rail in addition to the provided, actuable retaining springs.
- a sealing device is provided on the mounting body on each of its two long sides, wherein the two sealing devices each form one of the non-actuable retaining springs.
- all of the non-actuable retaining springs are formed by the sealing devices, in another embodiment, further non-actuable retaining springs, for example sheet metal springs, are provided in addition to the retaining springs formed by the sealing devices.
- the mounting body can be released from the support rail starting from the operating state by actuating the actuable retaining springs and by applying a vertical force applied between the support rail and the mounting body to overcome a spring retaining force generated by the non-actuable retaining springs. While the holding force of the actuatable retaining springs can thus be at least reduced, in particular eliminated, by actuating the actuatable retaining springs, starting from the operating state, the holding force or spring holding force ensured by the inactuatable retaining springs can be overcome by simply pulling the mounting body away from the support rail along the vertical direction.
- the system has a support rail protective cap, wherein in the operating state one of the mounting bodies points with one of its longitudinal ends towards the support rail protective cap and rests sealingly against the support rail protective cap with a sealing section of a sealing device provided on it as explained here, wherein the support rail protective cap can have a sealing surface corresponding to the sealing device as explained above.
- the mounting body can, as explained, be sealed against a The mounting body provided at the longitudinal end must be sealed.
- the invention proposes a system that has a mounting body and at least one support rail with a U-shaped cross-section.
- the system is designed to realize a longitudinally elongated luminaire.
- the support rail has a support rail base extending in a transverse direction between two support rail side walls and an open side opposite the support rail base in a vertical direction.
- the support rail side walls extend away from the support rail base in the vertical direction.
- the mounting body is arranged on the open side of the support rail and fixed to the support rail and, together with the support rail, encloses an interior space.
- the mounting body has a mounting body base that extends in the transverse direction between two mounting body side walls.
- Each of the support rail side walls has a holding section on its side facing the respective opposite support rail side wall.
- the mounting body is fixed to the holding sections.
- a retaining spring is fixed to the mounting body base between the mounting body side walls, which has a retaining arm on each of its two transverse sides that can be deflected in a spring-loaded manner in the transverse direction.
- each of the retaining arms engages behind the retaining section of the support rail side wall assigned to the respective retaining arm and presses vertically against it, pressing the mounting body side walls against the retaining sections to fix the mounting body to the support rail.
- the retaining arms thus rest on the side of the retaining sections that point vertically away from the mounting body base, so that, starting from the operating state, the mounting body can only be released from the support rail if at least one of the retaining arms is previously deflected in the transverse direction from its position in the operating state to such an extent that it is attached to the retaining section assigned to it. has moved past and thus no longer rests against the vertical side of the holding section facing away from the mounting body base.
- the mounting body side walls each have a projection as explained above, wherein the holding spring has a base body which is held pressed between the mounting body base and the aforementioned projections of the mounting body side walls and relative to which at least one of the holding arms, in particular both holding arms, can be deflected in a spring-loaded manner in the transverse direction.
- a seal is provided between the actuating element and the opening provided in the mounting body wall, which in the operating state has a Sealing of the actuating element with respect to the opening is ensured, wherein the seal is fastened to the holding arm or to the actuating element.
- the provision of the seal between the actuating element and the opening or the seal between the actuating element and the opening naturally means a provision or sealing between a boundary of the opening formed by the mounting body side wall and the actuating element, wherein the boundary of the opening defines the opening itself since it completely surrounds or forms the opening.
- the inventors have found that by providing the seal on the holding arm or on the actuating element, sufficient sealing can be easily achieved, as well as cost-effective production of the mounting body and particularly simple implementation of the operating state. Because the seal is provided on the holding arm or the actuating element, a tolerance regarding the alignment of the retaining spring relative to the opening can be ensured. In addition, this allows the assembly body to be manufactured without having to provide a seal, and the seal can be easily manufactured on small individual parts, namely the actuating element or the holding arm of the retaining spring.
- the seal, actuating element, retaining arm and mounting body are designed to correspond to one another in such a way that the seal moves relative to the mounting body when the actuating element is actuated. Sealing is therefore only ensured in the operating state, i.e. with an arrangement of the mounting body, retaining spring and support rail in which the retaining spring ensures that the mounting body is fixed to the support rail by engaging behind the retaining section using its retaining arm, whereas such sealing no longer necessarily needs to be ensured when the retaining arm is deflected by actuating the actuating element.
- the inventors have determined that such sealing can be dispensed with, since only in the operating state in which the system is intended use of a lamp manufactured with the system, needs to be reliably guaranteed.
- the inventors have therefore deliberately refrained from providing the seal on the mounting body itself and thus avoiding sealing grinding between the actuating element and the seal, accepting that when the actuating element is actuated, the seal is no longer guaranteed, which is not a problem, however, since such actuation is not to be expected during intended use of a lamp manufactured with the system, but only during its assembly or maintenance.
- the system is therefore particularly preferably designed in such a way that when the actuating element is actuated in this way, the seal is released from the mounting body at least in sections and the seal is thereby removed.
- the seal is integrated in one piece into the actuating element.
- the seal can be molded onto a base body of the actuating element by means of injection molding, in particular by means of a 2K manufacturing process, and/or locked onto a base body of the actuating element.
- the base body and seal are particularly preferably each made of plastic, in particular by means of an injection molding process.
- the seal and base body are particularly preferably made of a different plastic.
- the seal is particularly preferably made of a material that has a lower modulus of elasticity than the material from which the base body is made. In general, the base body is preferably made more rigid than the seal.
- the actuating element is locked to the holding arm in the operating state.
- the seal is locked to the holding arm in the operating state.
- the seal is locked directly to both the holding arm and the actuating element in the operating state.
- the seal is only locked to either the holding arm or the actuating element in the operating state and is only held fixed to the other of these two by a locking mechanism between the holding arm and the actuating element.
- the seal is held locked on the holding arm in an assembled state in which the retaining spring is attached to the mounting body and, starting from the assembled state, can be locked to the actuating element by inserting the actuating element into the opening in the mounting body.
- the actuating element is not fixed to the retaining spring, but the retaining spring is already fixed to the mounting body.
- the holding arm is aligned with the opening provided in the side wall of the mounting body. The seal can then be locked to the actuating element by inserting the actuating element from the outside through the opening.
- the seal can particularly preferably be locked to the actuating element during an actuation of the holding arm carried out by means of the actuating element.
- the seal can then be released from the holding arm while remaining locked to the actuating element when the operating state is realized, so that in the operating state the seal is locked to the actuating element but is no longer locked to the holding arm.
- This embodiment is particularly advantageous for transport and assembly of the system according to the invention, since the seal can be arranged in a protected manner in the assembly body until the components of the system are delivered to a construction site, and only by inserting the actuating element and locking it with the seal can the seal be released from the holding arm and fixed to the actuating element and thus the operating state can then be realized in which a reliable seal between the opening and the actuating element is ensured.
- the actuating element preferably rests with a stop on a stop surface of the holding arm, the seal being held pressed in the transverse direction between the holding arm and an inner side of the mounting body side wall and is thereby pressed around the opening against the inner side of the mounting body side wall.
- the resilient deflectability of the holding arm in the transverse direction thus ensures that the seal is pressed between the holding arm and the mounting body side wall, thus ensuring reliable sealing.
- the seal is pressed between the holding arm and the mounting body side wall independently of the actuating element in the operating state.
- the actuating element in the operating state, is fixed to the holding arm, in particular locked, and the seal is integrally provided on the actuating element or fixed to it, wherein the seal is ensured by the exercise of a spring force acting in the transverse direction of the holding arm in the direction of the mounting body side wall due to the fixation of the actuating element to the holding arm and the fixation or integral provision of the seal on or in the actuating element, a compression of the seal is ensured.
- the seal is elastically compressible in the transverse direction.
- the seal has a bellows-like section that is compressible in the transverse direction.
- the bellows-like section is elastically compressible.
- the invention proposes a system that comprises several mounting bodies and several support rails with a U-shaped cross-section.
- the system is designed to realize a longitudinally elongated luminaire.
- the support rails each have a support rail that extends in a transverse direction between two support rail side walls. extending support rail base and an open side opposite the support rail base in a vertical direction.
- the support rail side walls extend away from the support rail base in the vertical direction.
- the support rails with their U-shaped cross sections are arranged one behind the other in the longitudinal direction and are fixed to one another.
- the assembly bodies are arranged one behind the other in the longitudinal direction on the open side of one of the support rails and are fixed to this and, together with the support rails, enclose an interior space.
- Two of the support rails that are adjacent in the longitudinal direction are connected to one another in a sealing manner by means of a sealing sleeve.
- a sealing sleeve By providing such a sealing sleeve, the penetration of dirt at the joint between two adjacent support rails can be prevented as far as possible.
- the sealing sleeve has a sealing base and two sealing legs, forming a U-shaped cross section of the sealing sleeve.
- the sealing sleeve In the operating state, the sealing sleeve is arranged on the outside of both adjacent support rails.
- the support rails each form a projection on their outside with each of their two support rail side walls, which is spaced from the absolute vertical ends of the support rail side wall.
- the sealing sleeve has a retaining projection on each of its sealing legs, which in the operating state engages behind one of the projections of the support rail, realizing a vertical pressing force against this projection.
- the sealing sleeve can thus be subsequently applied from the outside to two adjacent, mutually fixed support rails and arranged on them in a particularly simple manner by placing it on these support rails starting from the outside of the support rail base of the two support rails.
- the sealing sleeve is particularly preferably designed in such a way that its sealing legs can be deflected elastically along the transverse direction, so that the sealing sleeve due to the spring-elastic deflection starting from the outside of the support rail base of the two adjacent support rails, it can be placed on them until the retaining projections of its sealing legs have come into engagement with the projections provided on the support rail side walls and a vertical pressing force is generated by the engagement.
- the interlocking of retaining projections and projections generates both a vertical pressing force between retaining projections and projections and a pressing force opposite to this vertical pressing force between the sealing base and the outside of the support rail bases of the two adjacent support rails.
- the retaining projection of each sealing leg, with its transverse end facing the support rail side wall in the operating state is less than 10% of a total transverse width of the sealing sleeve away from an outside of the sealing leg assigned to it facing away from the support rail side wall in the operating state.
- the end facing the support rail side wall in the operating state is thus only slightly spaced in the transverse direction from the corresponding transverse outside of the sealing leg. This ensures that the retaining projection of the sealing leg and the projection of the support rail side wall engage as far outside the transverse center of the support rail as possible, which can ensure particularly good sealing of the sealing sleeve on the outside of the two support rails.
- the retaining projection is spaced at least 10%, in particular at least 20% of a total vertical height of the sealing sleeve from a vertical end of the sealing sleeve formed by the sealing base. This spacing ensures a particularly good sealing of the sealing sleeve on the outside of the support rails, since the vertical pressing force between the retaining projection and the projection of the sealing leg and the support rail side wall and the corresponding spacing of the retaining projection from the sealing base over as large a distance as possible A sealing connection between the sealing sleeve and the outside of the support rail can be supported along the vertical extension of the sealing sleeve.
- the sealing base has a central transverse region, at each of whose two transverse ends an angled region of the sealing base is provided, over which the sealing base runs with its outer side both in the vertical direction and in the transverse direction.
- the central transverse region particularly preferably runs in a straight line in the transverse direction, whereas the two angled regions are both angled away from the central region and are preferably angled towards each other, i.e. they enclose an angle of ⁇ 180°, in particular ⁇ 160°, in particular ⁇ 150° between them.
- Such a design of the sealing base can ensure, in a particularly advantageous manner, a pre-tension of the sealing sleeve in the transverse direction, which supports the best possible sealing contact on the outer side of the support rail side walls.
- the sealing legs are arranged at an end facing away from the central region of each of the angled regions of the sealing base and run away from this in the vertical direction.
- the sealing sleeve engages vertically behind the support rail exclusively at its support rail base. In one embodiment, the sealing sleeve extends in the operating state in the vertical direction with its vertical end facing away from the sealing base up to the vertical end of the support rail facing away from the support rail base.
- the retaining projections are locked in the operating state with the projection of the support rail or the support rail side walls assigned to them in such a way that they overlap with them both over a vertical section and over a transverse section. Reaching behind the projection and the retaining projection is realized.
- This can be particularly advantageous for sealingly fixing the sealing sleeve on the outside of the support rails.
- the vertical extension of the vertical section is particularly preferably less than a tenth of the transverse extension of the transverse section. Of course, this refers to the extension length of the vertical section along the vertical direction or the extension length of the transverse section along the transverse direction.
- the sealing sleeve can be elastically snapped onto two adjacent support rails that are already fastened together to realize the operating state.
- the sealing sleeve can be elastically compressed in the transverse direction.
- the two longitudinally adjacent support rails are held fixed to one another by a coupling that is arranged within the receiving space formed by the two support rails, wherein the sealing sleeve can be snapped onto two support rails that are fastened to one another in this way, in particular starting from the support rail base of the two support rails. Sealing of the two support rails can thus be ensured by means of the sealing sleeve after the support rails have previously been fixed to one another by means of the coupling.
- the sealing sleeve is made of two different materials, wherein the first material has a lower modulus of elasticity than the second material and the sealing sleeve rests against the outer sides of the two adjacent support rails in the operating state with the first material.
- the sealing sleeve has a support body which is made of the second material and on which at least one sealing strip made of the first material is provided.
- the at least one sealing strip runs in the operating state over the entire support rail base and, starting from the support rail base, over at least 80%, in particular at least 90%, in particular 100% of the vertical extension of the support rail side walls.
- the sealing strip is a longitudinally uninterrupted strip which, in the operating state, rests with a first longitudinal section on a first of the support rails and with a second longitudinal section on a second of the support rails, wherein in particular the longitudinal sections run parallel to one another around a longitudinal axis, wherein in particular both longitudinal sections run next to one another over the same path length around the longitudinal axis and/or both longitudinal sections run both over the entire support rail base and, starting from the support rail base, over at least 70%, in particular at least 80%, in particular at least 90%, in particular less than 100% of the total vertical extent of the support rail side walls of the respective support rail, which they have starting from the support rail base up to the vertical end of the respective support rail opposite it.
- a particularly good seal can be achieved by means of such a sealing strip which is uninterrupted in the longitudinal direction.
- the support body is particularly preferably designed as a U-shaped support body, on the inside of which the sealing strip is arranged.
- the invention proposes a system with several mounting bodies and several support rails with a U-shaped cross-section.
- the system is designed to realize a longitudinally elongated lamp.
- the support rails each have a support rail base extending in a transverse direction between two support rail side walls and an open side opposite the support rail base in a vertical direction.
- the support rail side walls extend away from the support rail base in the vertical direction.
- the system also comprises a coupling with a U-shaped cross-section, which has a coupling base extending in the transverse direction between two coupling side walls and an open side opposite the coupling base in the vertical direction.
- the coupling side walls extend away from the coupling base in the vertical direction.
- the support rails are with their U-shaped cross sections aligned in the longitudinal direction one behind the other, with two longitudinally adjacent support rails being fixed to one another by the coupling.
- the coupling extends with one longitudinal section in each of the two adjacent support rails, and the adjacent support rails are each arranged with one of their longitudinal ends, namely with their mutually facing longitudinal ends, within a connection area of the coupling and face one another with these longitudinal ends.
- the connection area is an extension area of the coupling that extends in the longitudinal direction.
- the assembly bodies are arranged longitudinally one behind the other on the open side of one of the support rails and are fixed to this and, together with the support rails, enclose an interior space.
- the support rails in the operating state there is a need for the support rails to be sealed against one another within the connection area of the coupling, i.e. at the level of their mutually facing longitudinal ends, so that contamination cannot enter the interior between the two longitudinal ends.
- the system comprises several sealing inserts, whereby in the operating state one of the sealing inserts is arranged on each of the coupling side walls and extends over the connection area.
- the solution described thus provides that a sealing insert is provided on the coupling and thus within the respective receiving space formed by the support rails, which ensures a seal in the connection area of the coupling, i.e. at the point where the two support rails meet each other.
- the sealing inserts provided according to this solution can be provided as an alternative or in addition to a sealing sleeve as explained above for sealing the transition between two longitudinally adjacent support rails.
- the inventors have found that by providing such sealing inserts arranged within the support rails and provided on the coupling side walls, a seal can be achieved in a particularly simple manner at those points where the coupling itself cannot ensure sufficient sealing between the adjacent support rails.
- the sealing inserts can thus be specifically adapted to the geometry of the coupling so that the sealing inserts together with the coupling can ensure adequate sealing of the two adjacent support rails fixed to one another by means of the coupling.
- the sealing inserts are attached exclusively to the coupling, but not directly to the support rails.
- the sealing inserts are arranged on the inner sides of the coupling side walls facing one another.
- the sealing inserts are only arranged on the coupling side walls, but not on the coupling base, whereby the assembly and implementation of the sealing inserts can be particularly simplified and the fact can be used that the coupling base itself can advantageously ensure adequate sealing between the support rail bases of the adjacent support rails.
- the coupling side walls In order to fix the two adjacent support rails to one another, special measures must usually be provided on the coupling side walls, such as scratch springs, which prevent longitudinal movement of the support rails relative to one another starting from the operating state as far as possible. While the coupling side wall often has larger openings through which contaminants can penetrate, ie due to which the adjacent support rail side walls of the neighboring support rails are not adequately sealed against each other, such a problem does not exist in a large number of favorable designs of support rails and couplings of embodiments of a system according to the invention.
- the invention is therefore based on the special idea that the coupling and sealing inserts are designed together specifically to provide adequate sealing of the transition between two longitudinally adjacent support rails.
- the sealing inserts are made of a plastic, in particular at least partially made of an elastically deformable plastic.
- the coupling is made of a metal sheet, in particular in one piece by forming the Metal sheet.
- the sealing inserts are made entirely from an elastically deformable plastic.
- the sealing inserts are plate-shaped and arranged on an inner side of the coupling in the operating state. Due to their plate-shaped design, the sealing inserts can be arranged with their plate surface, i.e. their large plate side, along the coupling side walls, whereas they extend inwards away from the coupling side walls with their narrow sides, i.e. their small plate sides. Due to the plate-shaped design, it can be ensured that the sealing inserts take up as little space as possible within the support rail or within the coupling and can also ensure sealing over as large an area as possible.
- the sealing inserts each have a fastening arrangement that includes projections and/or recesses of the respective sealing insert.
- the coupling side walls each have a holding arrangement corresponding to the fastening arrangement, which includes projections and/or recesses of the respective coupling side wall.
- the holding arrangement and fastening arrangement are engaged, whereby the sealing inserts are fixed to the coupling.
- the fastening arrangement is particularly preferably pressed elastically compressed with the holding arrangement.
- the fastening arrangement is particularly preferably elastically deformed, whereas the holding arrangement is undeformed.
- all sealing inserts have the same fastening arrangement and all coupling side walls have the same holding arrangement. In general, all sealing inserts are preferably designed identically.

- the sealing inserts are reversibly attached to the coupling side walls can be attached and detached again.
- the sealing inserts can particularly preferably be attached to the coupling side walls without tools and in particular can be detached.
- the coupling has a plurality of openings in its coupling side walls, which are closed in the operating state by the sealing inserts arranged on the coupling side walls.
- a scratch spring protrudes from an inner side of the coupling to the outside through at least some of these openings.
- a plurality of scratch springs are provided on the coupling, wherein in the operating state at least one scratch spring rests on each of the two adjacent support rails, in particular at least one scratch spring on each of the support rail side walls of the adjacent support rails, and the support rails are held fixed to one another in the longitudinal direction by the contact of the scratch springs, wherein the scratch springs are each fixed to the coupling and each protrude through an opening provided in the coupling side wall, which is sealed in the operating state by one of the sealing inserts.

- An actuating element 5 is provided on at least one of the retaining arms of the retaining spring 20, which penetrates from the outside into the interior shown in Figure 1c through an opening provided in one of the mounting body side walls 22.
- a retaining arm of the retaining spring 20 assigned to this actuating element 5 can be deflected in a spring-elastic manner by the actuating element 5, so that by actuating the actuating element 5 the retaining arm can be released from the retaining section 14 assigned to it and the mounting body 2 can then be released from the support rail 1.
- FIG 2 comprising Figures 2a, 2b, 2c and 2d, a sealing device of an embodiment of the system according to the invention as well as further components of this system are shown schematically in various schematic principle representations.
- the sealing device has a web element 8 and a fixing element 7.
- the web element 8 has a T-like cross-section perpendicular to the transverse direction Y and forms the sealing surfaces of the sealing device.
- the sealing surfaces each comprise a partial surface 85 running in the vertical direction and a partial surface 84 running in the longitudinal direction, as shown in Figure 2a with reference to one of the sealing surfaces.
- the sealing device has such a sealing surface on each of its long sides. The sealing surfaces provided on the two long sides are identical.
- the web element 8 thus serves to provide sealing surfaces for two assembly bodies 2 adjacent in the longitudinal direction so that they can lie sealingly against the sealing device.
- the web element 8 has two spring regions 81, 82 on each of its two transverse sides, which are spaced apart from one another in the longitudinal direction X.
- the web element 8 further has a rod-like counter-region 83, which runs at least in sections in the longitudinal direction X between the two spring regions 81, 82.
- the counter-region 83 rests on an underside of the holding projection 14 assigned to it, whereas the spring regions 81, 82 rest on an upper side of this holding section 14.
- the sealing device further has a fixing element 7, as shown in detail in Figure 2b.
- the fixing element 7 has a fixing region 71 on each transverse side, with which it is arranged in the operating state in a recess 15 formed by the respective support rail side wall 12. Accordingly, the fixing element 7 engages behind the holding sections 14, which are formed at least in sections by the recess 15 and extend from this to the transverse center of the support rail 1, so that the provision of the fixing element 7 and its arrangement relative to the support rail 1 in the operating state allows the support rail side walls 12 to move apart along the Transverse direction is effectively prevented.
- the fixing element 7 rests on the web element 8 with a support area 74, which is generally advantageous according to the invention.
- the fixing element 7 has a pair of recesses 72 in each transverse end area, the recesses 72 of each pair being separated from one another by a partition 73.
- Each of these recesses 72 is designed to accommodate a tab web of a sealing device, explained in more detail below.
- a sealing device 9 of an embodiment of a system according to the invention and other components of this system are shown schematically in various basic representations.
- the sealing device 9 is arranged on one of the mounting bodies 2 of the system and fixed thereto. It rests with a base section on the mounting body base 21 and with a side section on the two mounting body side walls 22. It rests on the mounting body base 21 and mounting body side walls 22 in such a way that it is pressed against them in a sealing manner.
- the sealing device 9 forms a sealing section by means of which the mounting body 2 can be sealed against an adjacent mounting body 2 in the longitudinal direction X.
- the sealing section has a sealing lip 91 and a sealing tab, which in the present case has transverse end regions 95 which run in a meandering manner with respect to a plane running perpendicular to the vertical direction Z, as well as a central region 94 which connects the transverse end regions 95 to one another, as well as tab webs 96 which each form an absolute transverse end of the sealing tab.
- the sealing tab protrudes vertically over the mounting body side walls 22 and is vertically spaced from the sealing lip 91.
- the sealing lip 91 is designed in a linear manner and runs with a line section along each of the two mounting body side walls 22 and with a further line section which connects the first two continuously connects with one another, along the mounting body base 21.
- the sealing lip 91 already makes it possible to seal two mounting bodies 2 adjacent in the longitudinal direction X by having these sealing lips 91 abut one another in the longitudinal direction X.
- the sealing tab also makes a significant contribution to the sealing, as can be seen, for example, in Figure 3c.
- a sealing device as explained above is provided between the two mounting bodies 2, wherein the sealing tabs of the sealing devices 9, which are provided on the two mounting bodies 2 adjacent in the longitudinal direction X, seal against the partial surfaces 84, 85 of the sealing surfaces of the sealing device running in the longitudinal direction X.
- a sealing connection of the two mounting bodies 2 is thus still ensured by means of the sealing sections of the sealing devices 9 provided on them.
- the sealing lips 91 also seal against the partial surface 85 of the sealing device running in the vertical direction Z, so that a further advantageous seal is ensured.
- the particularly advantageous seal is also contributed to by the fact that the sealing device 9 has an overhang section with which it runs above a side of the mounting body side walls 22 facing away from the mounting body base 21, overhanging them and thus protruding over them in the vertical direction Z.
- the overhang section ensures a particularly reliable fixation of the sealing device 9 and the entire mounting body 2 to the support rail 1 in the operating state, ensuring a seal.
- the overhang section can press from above onto a holding section 14 of the support rail 1 and thereby ensure a sealing connection between the sealing device 9 and the holding section 14 and thus the support rail 1.
- the overhang section has several parts in this case.
- FIG. 4 which includes Figures 4a, 4b and 4c, shows the structure of the sealing device 9 of the embodiment described here.
- the sealing device 9 has a sealing element 910 and a stabilizing element 920, wherein the sealing element 910 forms the sealing section, the base section, the side section and the further part 92 of the overhang section explained above.
- the stabilizing element 920 is at least partially enclosed by the sealing element 910.
- the stabilizing element 920 and the sealing element 910 form guide rails 97, 98 with which they engage with one another.
- the sealing element 910 is produced by overmolding the stabilizing element 920, so that the stabilizing element 920 and the sealing element 910 are produced as a one-piece component by means of 2K injection molding.
- the part of the overhang section formed by the stabilizing element 920 overhangs the part of the overhang section formed by the sealing element 910, which is generally advantageous according to the invention. This is because the part of the overhang section formed by the stabilizing element 920 can thereby press the part of the overhang section formed by the sealing element 910 against the holding section 14 and in particular the mounting body side wall 22.
- the stabilizing element 920 is made of a stiffer material than the sealing element 910 and can therefore exert an advantageous contact force against the further part 92 of the overhang section formed by the sealing element 910 against the holding section 14.
- the part of the overhang section formed by the stabilizing element 920 is at least partially designed as an actuating section 93, so that for assembly and disassembly purposes, the sealing device 9 and thus also the assembly body 2 can be easily released via the actuating sections 93.

- the sealing device 9, as shown in Figure 5, is arranged on one of the mounting bodies 2 of the system in the operating state of the system according to the invention and is fixed to it, as can be seen from Figure 7. It rests with a base section on the mounting body base 21 and with a side section on the two mounting body side walls 22.
- the fixing of the sealing device 9 to the mounting body 2 is particularly advantageously ensured in the embodiment according to Figure 5 in that the sealing device 9 has a receptacle on each of its transverse sides, which is formed by two partial receptacles 991, 992, which are spaced apart from one another along the longitudinal direction X.
- a sealing web 99 runs between these partial receptacles 991, 992.
- the projection 23 of an associated mounting body side wall 22 is arranged in one of the receptacles, the sealing device 9 being arranged along the vertical direction Z between the projection 23 and the Mounting body base 21 is pressed vertically and is pressed laterally between the mounting body side walls 22.
- the sealing device 9 also has an overhang section which has a fastening section 900 which comprises a spring section 902 and a contact section 901.
- the sealing device 9 has sealing wall sections 960 which run between the contact section and the sealing tab and protrude vertically over the sealing tab, wherein the sealing tab has transverse end regions 95, a central region 94 and tab webs 96, as has already been explained with reference to the embodiment according to Figure 4.
- the sealing device 9 has a sealing lip 91 which has already been explained.
- the sealing device 9 has a sealing element 910 and a stabilizing element 920.
- the stabilizing element 920 and sealing element 910 are each made of plastic, in this case by means of an injection molding process, with the stabilizing element 920 being made of a harder plastic than the sealing element 910.
- the sealing element 910 and the stabilizing element 920 are each shown separately in Figures 5c and 5d, whereas the sealing device 9 is shown as a whole in Figures 5a and 5b.
- the receptacles or partial receptacles 991, 992 explained are at least partially formed by the stabilizing element 920, which is generally advantageous according to the invention, since this enables the sealing device 9 to be fixed particularly reliably to the mounting body 2.
- the fastening section 900 is at least predominantly formed by the stabilizing element 920, which is generally advantageous according to the invention.
- the spring section 902 is formed by the stabilizing element 920, which is generally advantageous according to the invention.
- the spring section 902 has a plurality of partial spring sections arranged one behind the other along the longitudinal direction X and spaced apart from one another and also has two side spring sections, each of which has a plurality of partial spring sections and a cross section in the manner of a U-shape.
- each side spring section is located on exactly one associated Holding section 14 of the support rail 1. Due to the described design, the spring section can be designed in a particularly simple and cost-effective way to provide a sufficient holding spring force on the support rail 1, with the focus on the operating state or on holding, as shown in Figure 7.
- the contact section 902 has two side contact sections, each of which forms an inclined surface section, with which they rest against the holding section 14 assigned to them in the operating state.
- the sealing element has an engagement section 911 and the stabilizing element 920 has a recess 9120, wherein the recess 9120 has several recess sections arranged one behind the other along the longitudinal direction X and spaced apart from one another, and the engagement section 911 has several projection sections arranged one behind the other along the longitudinal direction X and spaced apart from one another.
- the recess 9120 and the engagement section 911 engage with one another in an interlocking manner.
- the overhang section only rests with the part formed by the stabilizing element 920 and thus not with the engagement section 911 in the operating state on the
- FIG 6 shows a sealing device of an embodiment of a system according to the invention, as is included, for example, in the system shown in Figure 7.
- the sealing device has a web element 8 and a fixing element 7.
- the fixing element 7 is designed like a trough and has downwardly projecting fixing regions 71 with which it is arranged in a recess 15 formed in the respective support rail side wall 12 in the operating state, as can be seen in particular from Figure 7b.
- the fixing element 7 also has two recesses 72 running through the longitudinal direction, in each of which a sealing web 86 of the web element 8 is arranged in the operating state, as can be seen, for example, in Figures 6c, 7b and 7c.
- the web element 8 has two such sealing webs 86 which extend over the same longitudinal section, within which the counter regions 83 of the web element 8 run.
- the counter regions 83 are transversely spaced from the sealing webs 86, so that in the operating state, as can be seen for example from Figures 7b and 7c, the counter regions 83 press from below against a respective associated support rail projection 14, whereas the sealing webs 86 are transversely offset and run vertically above relative to the counter regions 83 and run on a transverse side of the holding sections 14, thereby providing a particularly good sealing effect or dust barrier.
- Figure 7a shows a section through components of the system perpendicular to the transverse direction Y
- Figures 7b and 7c show sections perpendicular to the longitudinal direction X, but at different longitudinal positions. From a view of Figures 7a, 7b and 7c together, it can be seen that in the operating state, the sealing tabs of the sealing devices 9, which are provided on the two adjacent mounting bodies 2, press against a respective different partial surface 84 of the web element 8, so that they are pressed together in a sealing manner by means of the web element 8, wherein in addition the sealing lips 91 press against a respective different partial surface 85 of the web element 8, which can lead to further sealing pressing.
- the sealing lips 91 can possibly move away from the web element 8, whereas the sealing tabs continue to press against the respective partial surface 84 of the web element 8 assigned to them due to the T-shaped design of the web element 8, which is generally advantageous according to the invention.
- spring areas 81, 82 and counter areas 83 By providing spring areas 81, 82 and counter areas 83, a particularly good fixation of the sealing device to the support rail 1 can be ensured, whereas by providing the sealing webs 86 and accommodating them in a respective recess 72 of the fixing element 7, a particularly good seal can be provided.
- FIG 8 comprising Figures 8a and 8b, the sealing sleeve 6 of an embodiment of a system according to the invention and other components of this system are shown schematically in various basic representations.
- the sealing sleeve 6 has a sealing base 61 and sealing legs 62.
- a holding projection 63 is provided on each of the sealing legs 62, which, in the operating state of the system, engages behind a projection of the support rail side wall 12 assigned to it and presses against this projection.
- a vertical pressing force is generated between the projection and the holding projection 63.
- the projection of the respective support rail side wall 12 is designed in this case in that the support rail side wall 12 has a notch that merges via projections into the sections of the support rail side wall 12 adjacent to it.
- Figure 9 shows a schematic diagram of a support rail protective cap of an embodiment of a system according to the invention.
- the system according to the invention can generally have such a support rail protective cap 100 at each of the two longitudinal ends of its support rail 1 or its support rail arrangement comprising support rails 1 arranged one behind the other in the longitudinal direction X.
- the support rail protective cap 100 has a support rail side wall receptacle 112 for each support rail side wall 12 and a support rail base receptacle 111 for the support rail base 11, as well as a notch receptacle 113 for the notch 13.
- the support rail protective cap 100 can be placed on a longitudinal end of a support rail 1 in such a way that it rests with a circumferential wall region 14 on an inner side of the support rail 1 and the support rail side walls 12 are arranged in the support rail side wall receptacles 112 and the support rail base 11 is arranged in the support rail base receptacle 111.
- the support rail protective cap 100 further comprises clamping projections 105, 196, by means of which a fixing of the support rail protective cap 100 to the support rail 1 is advantageously ensured.
- the support rail protective cap 100 forms a sealing surface 194, 195, which is designed to correspond to the sealing section of a sealing device 9 provided in a mounting body 2 of the system.
- the support rail protective cap 100 is therefore suitable not only for sealing the support rail, but also for sealing the transition between the support rail protective cap 100 and the mounting body 2. Accordingly, the sealing devices 9 are not only suitable for sealing two mounting bodies 2 adjacent in the longitudinal direction X against each other, but also for sealing the mounting body 2 against a support rail protective cap 100.
- FIG 10 comprising Figures 10a, 10b, 10c, 10d and 10e, an arrangement comprising an actuating element 5 and a seal 52 of an embodiment of a system according to the invention as well as further components of this system are shown schematically in various basic representations.
- the system comprises a retaining spring 20 with retaining arms 220, each of which is provided by means of a spring 211 on a base body 210 of the retaining spring 20 so as to be resiliently deflectable in the transverse direction Y.
- the spring 211 is manufactured integrally with the base body 210.
- the base body 210 has clamping projections 212 with which it can be clamped under projections 23 of mounting body side walls 22 to fix the retaining spring 20 to the mounting body 2.
- the retaining arms 220 each form a retaining arm projection 221 with which they rest on the top of one of the retaining sections 14 of the support rail 1 in the operating state as explained here, fixing the mounting body 2 relative to the support rail 1.
- the retaining arms 220 can be actuated by an actuating element 5 in the operating state from an outside of the support rail 1 and the mounting body 2 and thus from outside the interior space enclosed by them.
- the actuating elements 5, as shown in Figure 7d each penetrate through an opening provided in a mounting body side wall 22.
- the actuating elements 5 each rest with a stop 56, as shown in Figure 7d, on a stop surface 226, as shown in Figure 7c, of the respective holding arm 220, so that by actuating the actuating element 5 at its actuating surface 51 while displacing the actuating element 5 towards the transverse center of the support rail 1, the holding arm 220 can be deflected.
- a retaining projection 55 on the actuating element 5 and by providing a loss-prevention hook 223 it is ensured that the holding arms 220 are held captively on the base body 210 and that the actuating elements 5 are held captively on the holding arm 220 assigned to them.
- a seal 52 is provided integrally on the actuating element 5.
- the seal 52 presses with a sealing side 53 shown in Figure 7d against the inside of the mounting body side wall 22 assigned to the respective actuating element 5.
- this is done in that in the operating state the holding arm 220 exerts a spring force on the actuating element 5 along the transverse direction Y towards the mounting body side wall 22 due to its spring-elastic connection to the base body 210 in the transverse direction Z. Since the seal 52 is integrally provided on the actuating element 5, it is thereby pressed against the inside of the mounting body side wall 22.
- Figure 11 comprising Figures 11a and 11b, in Figure 12, comprising Figures 12a, 12b, 12c, 12d, 12e and 12f, and in Figure 13, comprising Figures 13a, 13b and 13c
- actuating element 5 and seal 52 or of a system according to the invention comprising such an arrangement is shown in schematic principle representations.
- the seal 58 has a bellows-like section 583 and is pressed with a sealing side 582 against the inside of the mounting body side wall 22. It is held locked on the holding arm 220 with a fixing section 581.
- the seal 58 When the holding arm 220 is actuated by means of the actuating element 5, the seal 58 is deformed in the transverse direction Y, whereby its bellows-like design continuously ensures a reliable seal between the opening and the actuating element 5.
- the seal 58 is held locked in an assembled state on the holding arm 220, as shown in Figure 9d. Starting from the assembled state, the actuating element 5 is locked to the seal 58 by inserting the actuating element 5 into the opening of the mounting body 2, whereby the seal 58 locks to the base body 57 of the actuating element 5.
- a locking device with locking sections 584, 585 is provided on the seal 58, by means of which the seal 58 can be locked to the base body 57 of the actuating element 5.
- the actuating element 5 has a base body 57 and the seal 58, whereby the seal 58 is made from a different plastic than the base body 57 and is manufactured in a different manufacturing step than the base body 57, whereby the seal 58 is locked to the base body 57 to realize the actuating element 5.
- the base body 57 and the seal 58 have locking devices 576, 577, 586, 587 that correspond to one another.
- FIG 14 comprising Figures 14a, 14b, 14c, 14d, 14e and 14f, a sealing insert of an embodiment of a system according to the invention as well as other components of the system are shown schematically in various schematic principle representations. It can be seen from Figure 14 that the embodiment shown comprises several sealing inserts 31, each of which is designed like a plate and is arranged on an inner side of one of the coupling side walls 302 in the operating state of the system.
- the coupling side walls 302 of the coupling 3 are connected to one another by a coupling base 301 and that the coupling base 301 can provide a sufficient seal between the support rails 1 at the transition between two support rails 1, but not the coupling side walls 302, since these have openings 300 through which a scratch spring 30 extends, whereby each of the scratch springs 30 is held scratched on one of the support rails 1 and thus the support rail 1 is fixed relative to the coupling 3 with respect to the longitudinal direction X. While the opening 300 is visible in Figure 14b and the system is shown in the operating state without the sealing insert 31, it is clear from the overview of the Figures Ile and 11f show that in the operating state the sealing insert 31 closes the openings 300.
- the sealing inserts 31 are each identically designed and have a large number of projections and recesses 311 as a fastening arrangement, and the coupling side walls 302 have a corresponding holding arrangement, with each of the projections of the fastening arrangement being assigned a recess 311 of the holding arrangement and each recess 311 of the fastening arrangement being assigned a projection of the holding arrangement.
- the sealing inserts 31 are fixed to the coupling side walls 302 in that their fastening arrangements are pressed in an elastically deformed manner with the holding arrangements of the coupling side walls 302.
- the sealing inserts 31 also each have recesses 313 in which the scratch springs 30 are movably arranged in the operating state, as well as covering areas 312 which are specifically designed to correspond to openings provided in the coupling side walls 302 in order to be able to close them in the operating state.
