  • Carrying device for carrying an electronic device within a receiving space of the carrying device.
  • the invention relates to a carrying device with a receiving space for receiving and holding a module that can be taken out of the receiving space again.
  • the invention further relates to a module that is designed to be inserted into the receiving space of the carrying device and to be removed from this receiving space.
  • WO 2017/153481A1 discloses a module as an electronic display unit, which is also called “Electronic Shelf Label” or ESL for short and which is part of its fastening element, which is structurally integrated into the ESL and for fastening the ESL to a carrying device designed as a shelf rail serves, has a pin-shaped blocking element that can be retracted magnetically.
  • the blocking element protrudes from the housing of the ESL and is used for locking into a groove or recess or a hole in the correspondingly designed shelf rail.
  • the ESL at the intended holding position in the shelf rail which defines a receiving space through its shape, so that removal from the shelf rail, theft of the ESL, as well as its displacement along the shelf rail is reliably prevented a separate special tool that is brought into direct contact with the ESL, with the help of a magnetic field that can be generated by the special tool, so that the ESL can be removed from the shelf rail directly from the holding position.
  • the need for this special tool has proven to be a disadvantage in several respects because it is basically an additional piece to use when working with the ESLs on the shelf rail.
  • This special tool is often lost or misplaced, leading to delays in changing or adjusting the positioning of the ESLs.
  • the replacement of this special tool is associated with considerable logistical problems, because in the case of equipment with a strong permanent magnet, special delivery and transport conditions must be observed.
  • the invention has therefore set itself the task of providing an improved carrying device, an improved module and a system consisting of such a carrying device and at least one such module carried by the carrying device.
  • the subject of the invention is therefore a carrying device, in particular a shelf rail, for carrying a module, in particular an electronic device, wherein the carrying device has an alignment wall for aligning the module inserted into the carrying device and the alignment wall has a longitudinal extent and a transverse extent running normal thereto, wherein the carrying device is designed in such a way that the module used as intended in the carrying device can be moved within the carrying device corresponding to or along the transverse extent of the alignment wall between a removal position and a holding position in which the module is aligned on the alignment wall, and that the Shape or the cross-section of the carrying device forms a removal opening at a distance from the alignment wall, through which the module can only be removed from the carrying device starting from the removal position.
  • the object of the invention is therefore a module, preferably an electronic device, particularly preferably an electronic shelf display sign, which is designed to be carried by a carrying device, in particular shelf rails, wherein the carrying device has an alignment wall for aligning the module inserted into the carrying device and the alignment wall has a longitudinal extension and a transverse extension running normal thereto, the carrying device being designed in such a way that the module inserted into the carrying device as intended within the The carrying device can be moved corresponding to or along the transverse extent of the alignment wall between a removal position and a holding position in which the module is aligned on the alignment wall, and that the shape or the cross section of the carrying device forms a removal opening at a distance from the alignment wall, through which the module can only be removed from the carrying device starting from the removal position, the module having a first dimension which corresponds to the transverse extent of the alignment wall and which is greater than the We ite of the extraction opening and is smaller than the transverse extent of the alignment wall.
  • the object of the invention is therefore a system that has a carrying device according to the invention and at least one module according to the invention.
  • the measures according to the invention therefore have the advantage that the module can be removed from the carrying device without an additional special tool.
  • no force has to be applied during removal that leads to elastic deformation or temporary change in shape of the carrying device in order to forcibly widen the removal opening in order to then be able to remove the module from the carrying device through the widened removal opening.
  • the user only needs to know that the module cannot be taken directly from the holding position, but must first be brought into the removal position before he can remove the module from the carrying device.
  • the carrying device can be implemented in a variety of ways.
  • it can be a table display that can be set up on a counter or fixed there if necessary.
  • the support structure can be designed as a clothing tag that can be fixed there hanging on clothing.
  • a shelf rail as the preferred embodiment of the carrying device.
  • the orientation of the carrying device and thus also the orientation of the module attached to it can also be arbitrary.
  • the carrying device can be made of a plastic or a composite material such as glass fiber reinforced plastic.
  • a preferably non-magnetic or non-magnetizable metal, such as aluminum, can also be used.
  • a module can also be designed as a non-electronic module, such as a pure placeholder or a conventional (non-electronic) shelf rail sign, which e.g.
  • Such a module can provide its function autonomously at the stopping position or be integrated into an electronic network.
  • a fully autonomous electronic device has its own power supply, such as a solar panel, removable battery, or rechargeable battery.
  • the power supply can However, it can also be implemented using other measures, such as using Power-Over-WiFi technology, which can be used to supply energy over a greater distance using radio signals, or using NFC technology (NFC stands for Near- Field communication) or RFID technology (RFID stands for Radio Frequency Identification), with the help of which the power can be supplied directly to the carrying device over relatively short distances.
  • NFC Near- Field communication
  • RFID Radio Frequency Identification
  • each device can have its own radio module that enables communication according to a (at least de facto) standardized communication method (e.g. ZigBee, WiFi, WI_AN, etc. ...) or according to a proprietary communication method (e.g. disclosed in WO 2015/ 124197 A1).
  • a (at least de facto) standardized communication method e.g. ZigBee, WiFi, WI_AN, etc.
  • a proprietary communication method e.g. disclosed in WO 2015/ 124197 A1
  • Each electronic device usually communicates with an access point to which it is assigned in terms of radio technology by prior registration.
  • the usually several access points each supply a group of electronic devices and provide a connecting bridge to a server or a cloud-based management instance, where management software is run from where the actual control or query of the electrical devices is coordinated or takes place.
  • a central supply device can also be provided for each carrying device, which supplies the electronic devices carried on the carrying device either with contact, i.e. by electrical lines (e.g. integrated into the carrying device), or contactless, i.e powered by capacitive or in particular inductive coupling (such as in the case of NFC or RFID).
  • This supply device then forms the interface to one of the previously mentioned access points.
  • each electronic device can have corresponding contacts with which it can make contact with the lines, which are preferably integrated into the carrying device.
  • each electronic device can have appropriate coupling means, such as Capacitance plate or inductance or coil with associated matching network and electronic circuit have.
  • the supply facilities can also be connected to a communication network by cable.
  • a central power supply unit can be provided for the energy supply for a group of supply facilities, for example.
  • a holding position is to be understood as a position in which the module remains in relation to the carrying device without further action after it has been placed in or on the carrying device.
  • a removal position is to be understood as a position from which the module can be removed from the carrying device or removed from the carrying device.
  • the module in the holding position is positioned at least slightly offset in terms of location compared to the removal position.
  • the module and the carrying device are designed or matched to one another in such a way that the module can be moved between the removal position and the holding position.
  • the module can therefore, for example, be displaceable or tiltable or pivotable.
  • the mobility can be limited to a single type of movement, i.e. only displacement, for example, or it can also include or allow a sequence of several movements, such as tilting or tilting or panning and displacement. This results in at least one clear offset movement with which the module can be moved from the holding position to the removal position (possibly also backwards).
  • the displacement of the module between the holding position and the removal position essentially takes place within the carrying device, ie within a receiving space which is delimited or defined by the shape of the carrying device and in which the module is accommodated.
  • the carrying device and the module can be designed or their designs can be coordinated in such a way that the mobility of the module from the holding position to the removal position (possibly and also vice versa) has to take place via several different movement processes or movement sequences in order to move the module from one position to another.
  • the carrying device and the module can be designed in such a way or their design can be coordinated in such a way that, for example, an initial tilting movement and a subsequent displacement or, for example, an initial displacement and subsequent tilting of the module is necessary to move the module from the holding position to the removal position too moved.
  • the carrying device and the module are preferably designed in such a way or their designs are coordinated with one another in such a way that the module can only be moved from the holding position to the removal position by means of a substantially clear course of movement or a clear sequence of movements.
  • the movements of tilting and displacement mentioned by way of example can also occur superimposed, so that the module can or must be tilted and displaced simultaneously, for example, in order to reach the removal position. It is also possible that these movements have to take place in a defined value range of the relevant parameter, such as tilting the module between 25° and 30° and/or shifting the module by 3 and 7 mm in a specific direction.
  • the (at least partial) superimposition of different movements or sequences can also structurally due to the dimensions or shape of the carrying device or the module.
  • one of the structural coordination of the configurations with one another can advantageously be carried out in such a way that the carrying device is configured in such a way that the width of the removal opening is smaller than the corresponding dimension (e.g. the height) of the module.
  • Targeted matching of the dimensions of the carrying device and the module to one another ensures that the module can be moved or shifted within the carrying device, i.e. in the receiving space between the two positions, namely the holding position and the removal position.
  • the removal opening prevents the module, starting from the holding position, from moving away from the alignment wall due to its dimensions, i.e. the width of the removal opening, which is slightly smaller than the corresponding dimension of the module, which is referred to below as the height of the module , ie essentially normal to the alignment wall towards the removal opening, can be removed directly from the carrying device through the removal opening. Since the width of the removal opening is dimensioned somewhat too small in relation to the height of the module, the module is blocked at the edges of the removal opening, i.e. within the receiving space, during such a movement starting from the holding position or with an attempt to carry out such a movement is held.
  • this can be formed, for example, by rods or strips delimiting it, which run at a distance from one another and at the respective distance from the alignment wall essentially parallel to the alignment wall, specifically parallel to the longitudinal extent.
  • the carrying device itself delimits the removal opening in a defined manner by its shape. It is therefore particularly advantageous that the carrying device has at least two boundary walls, namely a first boundary wall and a second boundary wall, and the boundary walls enclose the alignment wall on both sides along the longitudinal extent of the alignment wall and run essentially transversely to the alignment wall, in particular forming a C-profile together with the alignment wall, the removal opening being bounded by the free ends of the boundary walls.
  • the free ends of the boundary walls are oriented towards one another. These free ends form the edges of the carrying device in the form of lips and thus limit the removal opening in the shape of a lip, with the receiving space opening from the removal opening in the direction of the alignment wall, which has a greater width, i.e. the width of the removal opening between the lips.
  • the first boundary wall has a module-receiving groove adjacent to the alignment wall, which groove runs parallel to the longitudinal extension of the alignment wall and is designed for partially receiving the module in the removal position.
  • This module-receiving groove allows the module to be displaced away from the holding position and towards the removal position.
  • the module In the holding position, the module completely covers the width of the removal opening viewed from the receiving space. If the module has a screen, for example, then this is essentially unimpaired by the edges of the removal opening. The screen is therefore bordered by the edges of the removal opening on opposite screen edges. However, if the module is sunk in the module-receiving groove, that edge of the screen located adjacent to the module-receiving groove is positioned inwardly in the receiving space, offset behind the edge of the carrying device that delimits the removal opening, and is covered by this edge of the carrying device.
  • the module receiving groove is preferably separated from one of the edges of the carrying device by a step, which delimits the removal opening, as seen from the bottom of the groove.
  • this step is that the module or the edge of the module that is closest to the step before the module can enter the module-receiving trough must be displaced by the step width towards the alignment wall. Before moving from the holding position to the removal position, the module or a part of the module must be moved towards the alignment wall so that the module is no longer prevented from moving further by the step.
  • the module-receiving groove is particularly preferably designed in such a way that a module can be immersed with its first side (e.g. its lower side wall) so deeply into the module-receiving groove that the opposite side (e.g. its upper side wall) of the module the removal opening can be swung out.
  • the module receiving groove has a depth that allows the module to immerse itself so deeply with its one side wall, as in the present example the lower side wall, that the other side wall, in the present example the upper side wall, under that edge of the Carrying device can dive through, which limits the removal opening there adjacent to the upper side wall.
  • the module can only be removed from the removal opening when the module has been moved from the holding position to the removal position in a manner corresponding to the transverse extent, for example essentially parallel to the alignment wall.
  • this movement or displacement results in one of the edges of the module, which would otherwise be trapped within the support at its edge defining the ejection opening, now being brought into the clearance of the ejection opening and the module with this edge ahead can be pivoted or tilted out of the receiving space or receiving area and can be completely removed from the receiving space through the removal opening.
  • the distance of the removal position in relation to the holding position should therefore be selected in such a way that the module is moved far enough in relation to the edges of the removal opening so that it can be easily moved out of the removal opening in the removal position.
  • the movement order or sequence discussed for removal is that which is used in reverse order for inserting the module into the carrying device.
  • the removal position is therefore the same as the insertion position that the module assumes or into which the module is brought when it is inserted into the carrying device.
  • the preceding discussions regarding the geometry of the carrying device do not necessarily mean that the module always has to lie against the alignment wall in the holding position, possibly also in the removal position.
  • the actual facts can be affected by the shape and/or the dimensions of the interior of the carrying device, which forms the receiving space of the carrying device and which is used to hold the module and which is limited by the shape of the carrying device, and/or the shape and/or the Dimensions of the module, especially its thickness arise.
  • These parameters can, for example, also be dimensioned in such a way that the module can also move in the transverse direction normal to the orientation wall within the accommodation space.
  • the width of the removal opening can be adapted to the height of the front wall of the module or vice versa. This is advantageous when the module forms a shelf rail display and the front wall is essentially formed by a screen and this screen is to be unhinderedly visible through the carrying device in the holding position.
  • such a module can have further structural measures, such as one or more lips on the (upper and/or lower) side wall, which mean that the module cannot be removed directly from its holding position through the removal opening, as discussed .
  • width of the removal opening it should be stated in general that this is selected taking into account the dimensions of the front wall of the module used in the carrying device and the functionality or movement sequences discussed above so that the front wall is clearly and unhindered visible.
  • the Carrying device has at least one first automatic positioning means, with the help of which a module used as intended in the carrying device can be automatically positioned in the holding position.
  • This automatic positioning means can be implemented, for example, with the help of one or more springs, which act on one side of the inserted module, for example supported on the carrying device itself, for example supported on the bottom of the module-receiving groove slide or press the module into the holding position.
  • a leaf spring or the like can also be positioned at the locations mentioned and achieve this effect.
  • the module can therefore have at least one second automatic positioning means, with the aid of which a module which has been inserted into the carrying device as intended can be automatically positioned in the holding position.
  • This second automatic positioning means can also be designed analogously to that of the carrying device. However, it is localized in the module.
  • the second automatic positioning means is located in an edge area (e.g. in the area of the lower side wall) of the module which is furthest away from the edge area (e.g. in the area of the upper side wall) closest to the holding position.
  • the first automatic positioning means can be provided without the second automatic positioning means and vice versa.
  • both automatic positioning means can also be provided together.
  • the first automatic positioning means is formed by at least one first magnetic force positioning means, with the aid of which a module inserted as intended in the carrying device with the aid of a magnetic force acting between the module and the carrying device Force can be automatically positioned in the holding position.
  • the second Automatic positioning means is formed by at least one second magnetic force positioning means. This is preferably located in an edge area of the module, particularly preferably in the area of the rear wall or adjacent to the rear wall of the module, the rear wall being intended for aligning the module with the alignment wall.
  • the solution based on magnetism has the advantage that the maximum attraction force is present at the holding position, because there is the minimum distance between the magnetically attractive interacting elements, whereas in the spring-based solution, the respective spring has the lowest spring force in the holding position, because the spring is already most relaxed there.
  • the first magnetic force positioning means could be realized by one or more permanent magnets, which are used, for example, distributed equidistantly along the longitudinal extension of the carrying device.
  • the first magnetic force positioning means is realized by a magnetizable material.
  • the magnetizable material is locally localized, preferably in the form of a strip of material, particularly preferably in the form of a ferromagnetic metal bar.
  • the position of the strip of material or metal rail essentially defines the holding position along the transverse extension to which the set of magnets arranged in the module is attracted.
  • the localized magnetisable material in particular the ferromagnetic metal strip, is located at an edge region of the alignment wall, preferably along the length of the alignment wall, more preferably along the entire length of the alignment wall.
  • this ensures that there are no restrictions with regard to the positionability of the module along the longitudinal extent.
  • the module inserted into the carrying device is automatically conveyed as far as possible to the edge area of the receiving space and there, possibly in cooperation with the boundary wall running adjacent to it, not only positioned reliably but also oriented or aligned against two inner wall areas of the carrying device.
  • the automatic positioning or alignment of the module in the receiving space can also be achieved without the contacting interaction of the module with the boundary wall, namely solely by a magnetic force-based alignment of the module, which results from suitable positioning of at least two magnets in the module.
  • the two magnets align the module so that each of them is at a minimum distance from the first magnetic force positioning means of the carrying device.
  • the strip of material or the metal rail is preferably also positioned at a sufficient distance from the boundary wall along the alignment wall.
  • the first magnetic force positioning means In order to obtain the best possible automatic positioning and also alignment, it has proven to be particularly advantageous for the first magnetic force positioning means to be integrated essentially flush into an inner surface of the carrying device, in particular into the alignment wall. This prevents the module from tilting or getting caught during its automatic positioning or alignment caused by magnetic force.
  • the alignment wall In particular in the case of a configuration of the magnetizable material in the form of a wire, strip or rail, it has proven to be advantageous for the alignment wall to have a receiving shaft in which the first magnetic force positioning means is inserted. This allows easy installation and a reliable and reproducible determination of the position of the magnetizable material.
  • the second magnetic force positioning means is implemented by at least one permanent magnet.
  • This permanent magnet may be positioned in the backplane or adjacent thereto within the housing of the module.
  • the at least one second magnetic force positioning means is preferably formed by two permanent magnets which are located at a distance from one another along a rear wall of the module. This measure increases the magnetic force of attraction, which favors automatic positioning, and also improves the automatic alignment of the module within the support, as has already been pointed out.
  • the module has a rear wall which has at least two rear wall orientations which differ from one another.
  • the rear wall preferably has a first rear wall section, which runs essentially parallel to a front wall of the module, and a second rear wall section, which is oriented inclined from the first rear wall section towards the front wall, and the two rear wall sections along a (in particular straight line) running) dividing line meet, which runs parallel to the longitudinal extent of the alignment wall when the module is intended to be carried by the carrying device.
  • This configuration has the advantage that a module held in the holding position, in which the first rear wall section is held flat on the alignment wall, e.g first rear wall section lifts off the alignment wall. As a result, the holding force of the magnetic interaction through Clearance buildup to the alignment wall is reduced and the module is easier to move from the holding position to the unloading position.
  • the ratio of the dimensions of the respective rear wall sections, measured in the direction corresponding to or parallel to the transverse extension of the alignment wall, can be chosen such that the second rear wall section is shorter than the first rear wall section.
  • the structure of the rear wall sections can be used as a kind of translation to overcome the magnetic force, whereby a movement at one end of the module is translated into a larger movement at the opposite end of the module and there a correspondingly large distance between the first and second Magnetic force positioning means is obtained.
  • the tilting movement is made possible by an appropriate configuration (e.g. dimension and shape) of the receiving space adjacent to one (e.g. upper) end and the other (e.g. lower) end of the module.
  • the distance between the lip of the support adjacent to or bounding the module-receiving groove and the alignment wall of the support is slightly greater than the thickness of the module at that end of the module.
  • the depth of the module-receiving groove allows, at this end of the module, a non-contact tilt away from said lip toward the alignment wall relative to the bottom of the module-receiving groove.
  • the inner wall of the receiving area is formed such that the portion of the module there can easily move away from the alignment wall towards that lip during the tilting movement, i.e. at the If possible, the inner wall does not rub or cant or get caught there.
  • the carrying device is designed with a step between the module-receiving groove and the removal opening, this tilting movement also causes the part of the module previously located above the step (in the example discussed, the lower side wall or the rib or Bar) is moved over the edge of the stage, which allows the module to be moved from the holding position to the removal position.
  • the carrying device is designed such that the module used as intended in the carrying device can be at least partially, in particular completely, removed from the alignment wall in a direction normal to the alignment wall and positioned in an intermediate position.
  • This intermediate position is characterized in that the magnetic attraction force is reduced due to the increased distance from the alignment wall compared to the holding position such that the module can be displaced along the carrying device in the longitudinal direction of the carrying device without being removed from the removal opening.
  • the module can slide along the lips of the carrying device.
