Description

The invention relates to roller shutters having a door leaf capable of movement between an open position, in which it at least partially clears a wall opening and at least partially forms a preferably multi-layer roll over the wall opening, and a closed position, in which it at least partially closes a wall opening, which has several door leaf segments located one behind the other in the direction of movement of the gate leaf, wherein between two segments of the gate leaf there is at least one stabilizing device extending perpendicular to the direction of movement of the gate leaf in approximately the horizontal direction, and edges facing each other areas of the door leaf segments are held on this stabilizing device.

Such roller shutters are used, among other things, as so-called high-speed gates for closing industrial workshops. In this case, it is important, firstly, that the movement of the door leaf be correctly directed. Secondly, it is important that often only a small space is available to accommodate the door leaf in the open position. For this purpose, for example, the roller shutters of the above type described in WO 2018/219512 A1 can have hinge systems located in the area of the edges of the door leaf, which in the closed position extend in at least individual sections in the direction of gravity, and hinged systems attached to the door leaf for guiding the movement of the door leaf , each of which has several hinge links, hingedly connected to each other relative to the hinge axes running perpendicular to the side edges and approximately parallel to the plane of the door leaf. Moreover, in accordance with the said publication, the area occupied by the gate in the open position is reduced due to the fact that at least some of the segments of the gate leaf are made of flexible material, which itself adapts in the open position to the roll being formed and thus allows for a smaller diameter of the spiral in the open position . Thanks to the direction of the door leaf by means of the hinge links of the hinge system coupled to the stabilizing device, the tensile or shear forces that arise during the movement of the door leaf can be transmitted through the hinge system, so that even at high speeds of door movement, a reliable direction of movement of the door leaf is possible when monitoring so that the stabilizing devices of the door leaf are correctly coupled with the hinge links of the hinge systems. However, when operating the doors known from WO 2018/219512 A1 at high door speeds, it turned out that damage to the door leaf occurs in the area of transitions between the stabilizing device and the door leaf segments.

A curtain shutter consisting of curtain shutter strips and connecting profile strips according to the restrictive part of claim 1 is proposed in DE 3210560 A1.

In view of these problems in the prior art, the basis of the invention is to provide roller shutters in which high door movement speeds are possible while reducing the risk of damage to the door leaf.

In accordance with the invention, this problem is solved by improving the known roller shutters as proposed in the distinctive part of claim 1 of the claims.

The invention addresses the well-known fact that even with the kinematics described above, in which shear and tensile forces are transmitted through the frame formed by hinge systems and stabilizing devices, significant forces still arise in the transition region between the stabilizing devices and the edge regions of the door leaf segments. These forces arise in particular during the transition to the open position and the resulting redirection of the movement of the door leaf to produce a multi-layer roll, with particularly high forces observed when the door leaf segments are at least partially made of flexible material, as proposed in WO 2018/219512 A1 . For the gates proposed in this publication, the door leaf segments are clamped in stabilizing devices, under certain conditions, using a glass strip. But in this case, it may happen that the segments of the door leaf, despite the clamping function, slip relative to the stabilizing device and then do not return to their original state again, because this is prevented by the clamping function of the glass strip. Because of this, visually visible waves or, accordingly, warping of the door leaf may occur in the transition area between the stabilizing device and the door leaf segment.

Attempts have been made to eliminate this drawback in such a way that the door leaf segments, made under certain conditions from a flexible material, are fixed by means of a clamping strip relative to the stabilizing devices so that removal under dynamic load is just as unlikely as under static force. However, it turned out that the clamping points of the fixing strip are transferred to the door leaf segments in such a way that visual deterioration also occurs. And in this case, warping or, accordingly, similar damage occurs in the transition area between the stabilizing device and the door leaf segment.

It has been found within the scope of the invention that these disadvantages can be avoided by floating the support of the door leaf segments relative to the stabilizing device, without compromising the overall stability of the system. This invention uses something that is stable

- 1 043473 sizing devices and hinge systems available under certain conditions form a stable frame through which the forces arising during the movement of the gate can be transmitted without the need for rigid fastening of the door leaf segments to the stabilizing devices to stabilize the entire system. Therefore, a floating support is feasible, which allows for relative movement of the edge areas of the door leaf elements relative to the stabilizing device, without resulting in deterioration in the movement of the door leaf or, accordingly, in the stability of the entire gate structure. On the other hand, a floating support makes it possible to accept a gap that, under certain conditions, arises during the movement of the door leaf or, accordingly, relative movements between the stabilizing device and the door leaf segment without causing damage or visual deterioration of the door structure due to excessive force.

The floating support can enable not only relative movement between the edge region of the door leaf segment and the stabilizing device in the direction of movement of the door leaf, but also, under certain conditions, also in a direction running parallel to the floating-supported edge region or, correspondingly, perpendicular to the direction of movement of the door leaf, so that even with corresponding small deviations of the door leaf movement from the given trajectory, damage to the door leaf segments is unlikely to occur.

In order to avoid the door leaf segments being torn away from the stabilizing devices, the relative movement of the floating-supported edge region of at least one door leaf segment relative to the stabilizing device is limited by means of a limiting system, wherein this limiting system, in particular during relative movement, acts in a direction parallel to the direction movement of the door leaf.

In accordance with the invention, the restrictive system has an expansion of the edge region held in a floating manner in the thickness direction running perpendicular to the plane of the door leaf specified by the direction of movement of the door leaf and the stabilizing device, and a socket made in the stabilizing device for expanding the edge region held thereon in a floating manner, wherein this socket is has an orifice pierced by the transition region of the segment between the expansion and the free region of the segment outside the stabilizing device, the width of which in the thickness direction is greater than the width of the transition region in the thickness direction, but less than the dimensions of the expansion in the thickness direction.

In this embodiment of the invention, the stabilizing device according to WO 2018/219512 A1 is expediently formed by a stabilizing profile having a socket area for accommodating an extension of the edge area of the door leaf segment, wherein the socket of the stabilizing profile is matched to the dimensions of the door leaf segment so that the door leaf segment is held on stabilizing device with clearance and without clamping action. By coordinating the dimensions of the expansion with the mouth of the socket, it is possible to prevent the edge region of the door leaf segment from being pulled out of the socket in a direction running parallel to the direction of movement of the door leaf.

Another limitation of the relative movement of the edge region of the door leaf segment relative to the stabilizing device or, accordingly, the stabilizing profile can be achieved when the socket on its side opposite the mouth is limited by the bottom, and the distance between the mouth of the socket and the bottom in the direction of movement of the door leaf is greater than the length of the expansion of the held floating edge area in the direction of movement of the door leaf. The difference in size determines the possible gap of the floating fastening of the edge area relative to the stabilizing profile.

In one particularly preferred embodiment of the invention, the door leaf segment is formed by strip material, whereby the expansion of the door leaf segment can be carried out by bending the floating-held edge region relative to a bending axis running parallel to the stabilizing device. In this embodiment of the invention, no additional structural element is needed to form the extension of the door leaf segment. The bending of the door leaf segment in the edge region, which runs perpendicular to the direction of movement, can be carried out, for example, during a roller forming process. In this case, the edge region of the door leaf segment can be folded, for example, in the form of a hook onto itself, to thereby obtain an extension of the floating-held edge region in the thickness direction.

In another embodiment of the invention, the extension can be formed by thickening the edge region, in particular by gluing and/or welding the thickened edge. Both the expansion of a door leaf segment, made by folding the floating-held edge region, and the expansion, made by gluing and/or welding a thickened edge, can extend across the entire width of the door leaf. But such embodiments are also possible in which the expansion extends only over some part of the entire width of the door leaf. In particular, in the last described embodiment of the invention, the extension

- 2 043473 can also be formed by individual expansion elements installed on the edge of the door leaf segment, which are made, for example, in the form of bracket elements. Such expansion brackets can be U-shaped structural elements, which can be made, for example, from sheet steel. In the area of contact of these expansion brackets with the door leaf segment, hook-shaped protrusions can be provided to create a connection with a geometric closure between the expansion brackets and the edge of the door leaf segment made, for example, of a polymeric material, such as polycarbonate. The hook-shaped protrusions can also be made in the form of hooks with a notch. When the expansion brackets are placed on the edge of the door leaf, the expansion brackets engage with the door leaf segments and prevent the door leaf segment from being pulled out of the socket of the stabilizing device. Expansion brackets can extend across the entire width of the door leaf segment. But such embodiments are also possible in which two, three or more expansion brackets are fixedly mounted at a distance from each other on the edge of the door leaf segment.

With regard to the installation of the gate according to the invention, it has proven to be particularly convenient if the stabilizing device has at least two socket parts that are removably connected to each other, which form opening restrictions opposite to each other. In this embodiment of the invention, first the edge region of the door leaf segment having an extension can be applied to the limiting surface of the first socket part that defines the mouth in a direction running perpendicular to the main surface of the door leaf segment or, accordingly, the plane of the door leaf, and then the socket part is added, forming a second, different limiting surface of the mouth, with a positive connection possible between the two socket parts. For example, this other socket portion may snap onto the first socket portion.

When the stabilizing device has two spaced-apart receptacles for accommodating the mutually facing edge regions of adjacent door leaf segments, it has proven to be particularly advantageous if the upper recess in the closed position and the corresponding mouth are delimited by two removably connected receptacle parts. In this case, the upper edge of the door leaf segment in a direction running parallel to the stabilizing device can be pushed into the lower seat of the stabilizing device. Then the segment of the gate leaf can be threaded into the guide device of the roller shutter and after that the lower edge of the segment of the gate leaf is connected to the stabilizing device located underneath it, while the lower edge of the segment of the gate leaf is first applied to the limiting surface of the first nesting part of the stabilizing device that limits the mouth, and then the second nesting part a part in a direction running perpendicular to the plane of the door leaf is attached to the first socket part to form a socket for the lower edge region of the gate leaf segment.

With regard to the possibly desired sealing function, it may be advantageous if a sealing material is placed in at least one seat, preferably the upper seat of the stabilizing device, preferably in the region of the bottom of this seat. Additionally or alternatively, this sealing material can also be provided between the expansion in the edge region of the door leaf segment and the mouth of the seat. With this arrangement, shock absorption can be achieved during the movement of the door leaf if the extension hits the edge of the mouth. In this way, a slight tension can also be achieved between the stabilizing device and the door leaf segment, which can even out small tolerances. The sealing material located between the extension and the mouth can tightly hold the plate in its position and reduce or completely prevent possible noise when the door segment moves relative to the stabilizing device. A suitable sealing material can be inserted into the socket of the stabilizing device or installed directly on the extension of the door leaf segment. In this case, we can talk about a sealing material that swells when moisture penetrates. Since in the area of the lower sockets in the closed position moisture can hardly penetrate into these sockets, sealing material in these sockets is, as a rule, not needed. As indicated in the above explanations, the present invention finds particular advantage in applications such as gates in which the segment having at least one floatingly supported edge portion has at least one plate which is, at least in certain portions, made of flexible and /or transparent material such as, for example, polycarbonate.

In terms of improving thermal protection, it has proven particularly advantageous if the door leaf segment having at least one floating-supported edge region has at least two plates spaced apart in the door leaf thickness direction and running approximately parallel to each other, each which has at least one edge region held on a stabilizing device and facing an adjacent segment of the door leaf, wherein at least one edge region of at least one plate is held in a floating manner on the stabilizing device so that relative movement of this edge region relative to the stabilizing device is possible devices at least

- 3 043473 direction of movement of the door leaf. This edge region can be supported on the stabilizing device in a similar manner as already described above. In this regard, it has proven particularly convenient if the at least one stabilizing device has two receptacles spaced apart in the direction of the door leaf thickness for placing a door leaf segment in each one edge region of the plate.

The door leaf segment plates in the embodiment just described are in the open position at a radial distance from each other. They move into the open position along trajectories located at a radial distance from each other and are deformed accordingly differently. Therefore, when the door leaf moves to the open position, under certain conditions, a short-term collision may occur if the edge areas of the plates are made identically and are placed in identical sockets of the stabilizing device. To overcome this drawback, one particularly preferred embodiment of the invention provides that at least one edge region of the inner (outer) plate facing the roll axis (facing away from the roll axis) is held with a larger gap relative to the stabilizing device than the corresponding edge region facing the roll from the roll axis (facing the roll axis) of the outer (inner) plate. For this purpose, the distance between the mouth of the seat for the edge region of the radially inner (outer) plate and the bottom of this seat in the direction of movement of the door leaf can be greater than the corresponding distance of the seat for the edge region of the radially outer (inner) plates. In this way, possible path differences (relative motion) can be compensated for by different trajectories of the individual plates.

Due to the described double plate system, an air cushion occurs. The resulting chamber can be closed in the area of the edges of the plates running parallel to the direction of movement of the door leaf. For this purpose, in the area of at least one of the edges of at least one segment running parallel to the direction of movement of the door leaf, preferably between the limiting surfaces of the plates facing each other, a filling material can be provided, which in one of the preferred embodiments of the invention can be made of pliable material, such as, for example, an elastic rod. Elastic mats, such as foam, which are glued or fixed mechanically, can be used as a filling material. Thus, the filling material also allows for the necessary mobility when moving the door leaf to and from the open position. Additionally or alternatively, fan-shaped polymer elements can also be used as filler material, which are connected to each other in the form of a hinge and can be snapped onto the plate.

Within the scope of the invention, it is also possible to use an elastic mat or elastic fan elements in door leaf segments that have only one plate to compensate for the displacement between the plate and the reinforcing profile in the edge region. In this way, a seal can be achieved relative to the side of the door. Since the door leaf segments of the gates proposed by the invention are usually made transparent at least in certain areas, within the framework of the invention it is particularly preferable if the filling material is 50% or less, in particular 20% or less, of the width of the door leaf extends in a direction running parallel to the stabilizing devices, so that the transparency of the door leaf segments is only slightly impaired.

In terms of the desired thermal separation between the inner side of the door leaf (inner space) and the outer side of the door leaf (outer space), it has proven to be particularly advantageous if at least one stabilizing device has at least two spaced apart in the thickness direction of the door leaf stabilizing elements that are connected to each other by means of a connecting element made of thermally insulating material. Thus, by using stabilizing elements having sufficient strength, such as, for example, stabilizing elements made of steel or aluminum, satisfactory stabilization can be achieved without compromising the thermal separation.

In terms of providing gates that enable high gate movement speeds, there are provided, preferably in the area of the lateral edges of the door leaf, extending in the closed position at least in certain sections in the direction of gravity, and hinged systems attached to the door leaf for guiding the movement of the door leaf, which can interact with corresponding fixed guide devices, such as, for example, guide rails, each of the hinge systems having several hinge links hinged to each other relative to hinge axes extending perpendicular to the direction of movement or, respectively, to the lateral edges of the door leaf, so that the door leaf is connected to these hinge systems by means of stabilizing devices. In this respect, the design of the gate according to the invention corresponds to the design of the gate described, for example, in WO 2018/219512 A1. The contents of the disclosure of this publication with respect to the implementation of the hinge systems and the guide bar, as well as the connection of the stabilizing devices to the hinge systems are incorporated by direct reference into this description.

According to the known gates, the roller shutters proposed by the invention can also have at least one segment of flexible material located between two stabilizing devices, with the lateral edge of the segment running approximately perpendicular to the stabilizing devices, as well as to the hinge axes and approximately parallel to the hinge systems and the direction of movement of the gate web, may extend over two, three or more hinge links, and at least one edge region of the segment may be supported on the stabilizing device in a floating manner.

In this case, according to WO 2018/219512 A1, at least one stabilizing device can extend approximately parallel to the hinge axis and along this axis be connected to at least two, preferably at least two, hinge systems provided at opposite lateral edges of the door leaf. To increase the overall stability of the system, at least one reinforcing strip extending parallel to the side edge of the door leaf or, accordingly, to the direction of movement of the door leaf and fixed to the door leaf, can be provided. In a similar way to the gates according to WO 2018/219512 A1, at least one oval-spiral guide track can be provided under certain conditions to guide the movement of the door leaf and to determine the open position of the door leaf, with at least one hinged The link on its side facing away from the door leaf may have a guide system that interacts to direct the movement of the door leaf with the guide track, which preferably includes at least one guide roller supported for rotation relative to the roller axis running parallel to the hinge axes, which is preferably at least In the open position, the door leaf is placed in the guide track.

With regard to the simple adaptation of the door leaf structure of the roller shutters according to the invention, it has proven to be particularly advantageous if a stabilizing device extending parallel to the hinge axis is connected only to the hinge systems. This embodiment of the invention makes it possible to vary the design of the door leaf stabilization while maintaining the same design of the individual door leaf segments or plates, when a stabilizing device connected only to the hinge systems can be installed on the hinge systems regardless of the size of the individual door leaf segments. It is not fixed to the segments or, accordingly, to the plates of the door leaf. Therefore, the installation of this additional stabilizing device does not require adaptation of the geometry of the segments or, accordingly, the door leaf plates. The possibility of varying the installation of this stabilizing device is limited only by the pitch of the hinge links of the hinge system.

When additional collision protection is to be provided for the roller shutters according to the invention, a stabilizing device connected only to the hinge systems can be located between the lower and the stabilizing devices connected to the roller shutter plates. However, within the framework of the invention, it has proven to be particularly expedient if a stabilizing device not connected to the door leaf segments is located between two upper stabilizing devices connected to the segments. In this way, a seal adapted to the height of the wall opening can be implemented in the area of the lintel of the wall opening without the need to change the geometry of the door leaf segments and other components of the roller shutter proposed by the invention.

In this regard, it has proven to be particularly expedient if the stabilizing device connected only to the hinge systems, but not to the door leaf segments, has a sealing system applied to the lintel of the wall opening on its side facing away from the adjacent door leaf segment and/or has a sealing system on its side facing the segment. at least one extending approximately parallel to the hinge axes, preferably substantially along the entire width of the door, and a sealing strip applied to the adjacent segment.

According to one of the particularly preferred embodiments of the invention, the leading edge of the door leaf during the opening movement can be formed by a leading stabilizing device, which is connected without the possibility of rotation to the upper edge of the segment of flexible material in the closed position, which is connected without the possibility of rotation to the guide system. Thanks to this system, unwanted bulging of the door leaf segment is prevented, as explained in detail in WO 2018/219512 A1.

To obtain a tight guide end, it has proven expedient if at least one hinge link of one hinge system is equipped with a sealing system applied in the closed position to the limiting surface, in particular the inner limiting surface, of the door leaf, as explained in detail in WO 2018/219512 A1. Further, also within the framework of this invention, a tensioning device can be provided that is engaged during the opening movement with the edge of the door leaf lagging behind during the opening movement and tensioned during the opening movement to slow down the opening movement and to provide a tension force displacing the door leaf from the open position to the closed position .

As indicated in the above explanation, the gate according to the invention advantageously has a guide device for directing the movement of the door leaf between an open position and a closed position. In this case, the invention is used with particular advantage for gates that allow high speed movement of the gate. For this purpose, the guiding device may provide non-contact magnetic guiding capability. For this purpose, the guide device may have a device for creating a magnetic field located on the side of the door leaf and a device for creating a magnetic field that is stationary relative to the wall opening, and these devices for creating a magnetic field are designed to obtain a non-contact direction of movement of the door leaf along at least one section of a given trajectory in the region of at least one of the side edges opposite each other.

Suitable guide systems are described in PCT/EP 2019/058221. The contents of this publication with respect to magnetic field guiding devices and systems are hereby incorporated by express reference into this specification. Of particular importance in this regard is that the guide system has at least one guide rib located motionless relative to the wall opening and extending along a certain section of a given trajectory, having two outer limiting surfaces, and at least two guide devices fixed to the door leaf, while the first outer limiting surface of the guide rib forms a guide surface for the first guide device, and the second outer limit surface of the guide rib forms a second guide surface for the guide device, so that the guide rib is placed between the guide devices fixed to the door leaf. In this case, at least one guide device, alternatively or in addition to devices for creating a magnetic field, may have a guide roller supported with the possibility of rotation relative to a path running perpendicular to a given path and in the closed position approximately parallel to the door leaf to the roller axis, which, when the door leaf moves, rolls along the guide surface of the door leaf.

If non-contact direction of movement of the door leaf is used using devices for creating a magnetic field, at least one device for creating a magnetic field, preferably at least one device for creating a magnetic field located on the side of the door leaf, can have at least one permanent magnet. Expediently, this device for creating a magnetic field, located on the door leaf side, can have two permanent magnets located on opposite sides of the guide ribs, which are fixedly mounted on one common holder, which is thrown onto the edge of the guide fin located on the door leaf side. Further details of magnetic field generating devices are explained in PCT/EP 2019/058221, the contents of the disclosure of which also regarding magnetic field generating devices are incorporated by direct reference into this specification.

The invention is explained below with reference to the drawing, to which direct reference is made with respect to all details essential to the invention and not revealed in more detail in the description. The figures show:

In fig. 1 shows two door leaf segments 110 and 120 of a gate 100 according to the invention, located one behind the other in the direction of movement of the door leaf indicated by the double arrow P. Between the door leaf segments 110 and 120 there is a stabilizing device made in the form of a stabilizing profile 200. The stabilizing profile 200 extends in a direction running perpendicular to the direction P of movement of the door leaf, approximately in the plane of the door leaf. The lower edge of the upper segment 120 of the door leaf is held floating in the area of the upper seat 230 (cf. Fig. 2) of the stabilizing profile 200, while

- 6 043473 while the upper edge of the lower door leaf segment 110 is held floating in the lower seat 240 (cf. Fig. 2) of the stabilizing profile 200. The upper edge of the door leaf segment 120 is held on another stabilizing profile 200 in the same way as the lower edge of the segment

110 of the door leaf is held on the lower stabilizing profile 200.

The stabilizing profiles 200 are attached to a hinge system 300 extending approximately parallel to the direction of movement of the door leaf or, correspondingly, parallel to the side edge of the door leaf 100. The hinge system 300 includes several hinge links 310 located one behind the other in the direction of movement of the door leaf and hingedly connected to each other with each other relative to the hinge axes running perpendicular to the direction P of the door leaf movement. In this case, three hinge links 310 are located between two adjacent stabilizing profiles 200. In other embodiments of the invention, only one or two or four or more hinge links can be provided between the stabilizing profiles 200. A stabilizing profile can also be provided in the area of each connection between successive hinge links.

The hinge system, on its side facing away from the door leaf segments 110 and 120, has guide rollers 320, which are rotatably supported relative to the roller axes running parallel to the hinge axes. The guide rollers 320 are arranged in pairs in the area of each hinge axis in such a way that they can accommodate a guide rib between them and can roll along the opposite limiting surfaces of the guide rib, thus allowing the direction of movement of the door leaf, which is described in PCT/EP 2019/058221 .

As can be seen especially clearly in FIG. 2, extending parallel to the hinge axes and parallel to the stabilizing profile 200, the upper edge region 112 of the door leaf segment 110 is located in the socket 240 of the stabilizing profile 200. The upper edge 112 of the door leaf segment 110 is made by folding the upper edge of the door leaf segment 112 onto itself in the form of an extension in plane of the door leaf, defined perpendicular to the direction P of movement of the door leaf and the stabilizing profile 200. Starting from the extension 112, the door leaf segment 110 extends in a transition region through the mouth 250 of the stabilizing profile 200 downwards and outside the mouth 250 is free, as can be seen in FIG. 1. In the same way, the door leaf segment 120 has an extension 122 placed in the housing 230 of the stabilizing profile 200. Starting from the extension 122, the door leaf segment 120 extends in a transition region through the mouth 225 upwards and is free outside the mouth 225.

The mouth 250 is limited by limiting surfaces 232 and 242, the distance between which in a direction parallel to the thickness direction of the door leaf is less than the thickness of the extension 112, but greater than the thickness of the transition region of the door leaf segment 110 between the extension 112 and the free area outside the stabilizing profile 200 Similarly, the mouth 225 is limited by limiting surfaces 212 and 222, the distance between which in the thickness direction of the door leaf is less than the thickness of the extension 122, but greater than the thickness of the transition region between the extension 112 and the free area of the door leaf segment 120 outside the stabilizing profile 200.

As can also be seen in FIG. 2, the stabilizing profile 200 is made of two parts 210 and 220 detachably connected to each other. In this case, the recess 240 on the lower edge of the stabilizing profile 299 is completely formed by the first part 210 of the stabilizing profile, while the socket 230 on the upper edge of the stabilizing profile 200 is formed both parts 210 and 220 of the stabilizing profile. The first limiting surface 212 of the mouth 225 is formed by the first stabilizing profile portion 210, while the second limiting surface 222 of the receptacle 230 is formed by the second stabilizing profile portion 220.

To install a roller shutter of the type shown in the drawing, the upper edge of the door leaf segment can be pushed in a direction running parallel to the stabilizing profile 200 into the socket 240, while the transition area between the extension 240 and the free area of the door leaf segment outside the stabilizing profile 200 penetrates the mouth 250. Prepared in this way Thus, the module can be threaded into a guide device, which may consist of a guide rib located between guide rollers 320. Thereafter, the lower edge 122 of the door leaf segment can be applied to the limiting surface 212 of the first stabilizing profile part 210, and the second stabilizing profile 220 is latched onto the first stabilizing profile profile 210 to form an orifice 225, which is pierced by a transition region between the gate segment extension placed in the slot 230 and the free area of the gate segment outside the stabilizing profile.

The distance between the limiting surfaces 212 and 222 or 232 and 242, respectively, of the mouths 225 or 250, which are opposite to each other, is greater than the thickness of the transition regions penetrating these mouths. This prevents clamping action in the transition areas.

- 7 043473

Further, the distance between the mouth 225 or 250 and the bottoms of the slots 230 and 240 opposite the corresponding mouths 225 or 250 is greater than the length of the extensions 122 or 112 in the direction of movement of the door leaf. This ensures the possibility of relative movement of the door leaf segments 110 and 120 relative to the stabilizing profile 200.

In the area of the bottom of the socket 230 there may be a sealing material which, under certain conditions, swells when moisture penetrates.

Shown in FIG. 3, the embodiment of the invention differs from the embodiment explained using FIG. 2, essentially in that between the curved lower edge of the plate 120 that forms the extension 122 and the lower limiting surface of the part 220 of the stabilizing profile 200 there is a shock-absorbing element 230, which, firstly, seals the plate 120 supported in a floating manner in the stabilizing profile 200, and secondly and second, it creates a floating-supported tension in the stabilizing profile 200 of the plate 120, which helps to equalize tolerances and hold the plate 120 tightly in position. Further, the damping element 140 reduces noise that may occur when the folded lower edge of the plate 120 moves in the seat 230 and hits the lower limiting surface of the stabilizing profile portion 220.

Shown in FIG. 4, the embodiment of the invention differs from the embodiment of the invention shown in FIG. 1 and 2, essentially in that the door leaf segments have two plates 120a and 120b extending substantially parallel to each other, each of which is made in the form of flexible polycarbonate plates. The lower edges of the plates 120a and 120b are each provided with an extension made by folding these edges, which are supported in a floating manner in the seats 230a and 230b of the stabilizing profile 1200. The upper edges of the plates 110a and 110b of the lower segment are held in the seats 240a and 240b of the stabilizing profile 1200. Between the plates 120a and 110b 120b or 110a and 110b, respectively, is provided with an air cushion 180 that contributes to thermal protection. The air cushion 180 is closed on edge segments 120 and 110 running parallel to the direction of movement P, provided between the plates 120a and 120b or, respectively, 110a and 110b by elastic cushions 190. These cushions 190 can be made in the form of elastic rods. For example, elastic mats made of foam material, which are glued or fixed mechanically, can be used. The elastic design of the cushions 190 also allows for the necessary mobility when screwing the door leaf into the spiral-shaped guide track when reaching the open position.

Additionally or alternatively, in the chamber 180, fan-shaped polymer elements that are connected to each other in the form of hinges can also be snapped onto the plate. It is also possible to use corresponding elastic mats or elastic fan elements for door leaf segments having only one plate, which are shown in Fig. 1 and 2, to compensate for the displacement between the plate and the stabilizing profile in the wall area. This can improve the seal of the door leaf in the closed position.

Shown in FIG. 5, the embodiment of the invention differs from the embodiment explained using FIG. 4, essentially in that the chamber 2230b of the stabilizing profile 2200, which serves to accommodate the extension 230b on the lower edge of the plate 110b, in the direction of movement of the door leaf, has a greater depth than the chamber 230a, which serves to accommodate the extension 122a made on the lower edge of the plate 110a. . This ensures that the radially inner plate 110b in the open position is supported in the seat 230b with a larger gap than the radially outer plate 110a in the open position. In this way, various deformations of the plates 110a or 110b can be compensated for when the door leaf reaches the open position, as explained in FIG. 5b).

Shown in FIG. 6, the embodiment of the invention differs from the embodiment of the invention explained using FIG. 5, essentially in that the stabilizing profiles 3200 are made of only three parts, with parts 3210, 3220, 3230 made following each other in the direction of the thickness of the door leaf. The inner part 3210 of the door leaf in the closed position of the door leaf, as well as the outer part 3220 of the stabilizing profile 3200 in the closed position, is made of a metallic material. This gives the stabilizing profile the necessary stability. The portions 3210 and 3220 are connected to each other via connecting members 3230 made of a thermally insulating material, such as, for example, a polymeric material. Thus, by ensuring sufficient overall stability of the stabilizing profiles 3200, heat loss between the interior space and the exterior space through the stabilizing profiles 3200 can be effectively reduced.

Shown in FIG. 7, the embodiment of the invention differs from the embodiment of the invention shown in FIG. 1 and 2, essentially in that between the stabilizing profiles 200, which are fixedly mounted on the lower and upper edges of the plates 110, 120, there is a stabilizing profile 400, which is attached exclusively to the hinge links of the hinge system 300. This additional stabilizing profile 400 can be placed regardless of the geometry of the plate and installed to accommodate the lintel seal depending on the height of the wall opening. For this purpose, the stabilizing profile 400 on its side facing away from the plates 110, 120 is equipped with a sealing element 410, while on the side facing the plate 120 it is equipped with hose seals 420, which are adjacent to the plate 120. Since the additional stabilizing profile 400 is not fixed on the plates 120, it can be attached independently of the geometry of the plate to any hinge links 310. In this way, the position of the seal 410 can be adapted to the height of the wall opening. This achieves not only an improved sealing effect, but also increased overall stability.

In fig. 8 schematically shows a plant for the production of plates for door leaf segments according to the invention of the roller shutter. When using the one shown in FIG. 8 of the installation, the polymer strip, at least partially composed of polycarbonate, in the form of a coil material is unwound from the unwinder 510 in the moving direction F. The resin strip passes through an edge trimmer 520, which adjusts the precise width of the resin strip, and then through a two-head roll forming unit 530, in which the edges of the resin strip, parallel to the movement direction F, are folded to create an expansion of the plates. The profiling installation, as can be seen in FIG. 8, has a plurality of forming rollers, which step by step bend the edges of the strip of material. After leaving the two-head forming machines 530, the plates of a given length are cut along a dividing line running perpendicular to the direction F of movement from the strip of material using a separating unit 540 and stacked on the output table 550. The following features of the methods proposed by the invention are of particular importance within the framework of this invention. They may be essential to the invention individually or in combination with each other:

The polymer strip is produced by extrusion and wound into a reel or roll, respectively. In this case, the width of the polymer strip or, accordingly, the width of the coil is obtained from the size of the extruder;

the width of an extruded polymer strip, such as, for example, an extruded polycarbonate strip, varies. With the help of an edge trimming station, the strip of material can preferably be precisely trimmed to the desired width before entering the deformation station;

In the edge trimming station, a wider polymer strip can be cut to a narrower size. This way the required plate size can be adjusted depending on the gate size;

A polymer strip, in particular a polycarbonate strip, after passing through a deformation device made under certain conditions in the form of a two-head profiling installation, can have significantly higher restoring forces than steel. Therefore, when carrying out the method proposed by the invention, significant excess bending is carried out to ultimately obtain the desired contour. It is also taken into account that the deformation can also continue to recover over time, and the deformed state under the influence of restoring forces can only slowly leave the shape obtained after leaving the deformation station;

To reduce the restoring forces, it turned out to be advisable to support the deformation process with heat.

When using polycarbonate strips, these strips are advantageously heated at least in the deformation region to a temperature of 150 to 170°C. This achieves the following effects.

1. Softer deformation occurs at a lower load on the polycarbonate and at the same time prevents the formation of cracks in the deformation area.

2. Deformation stresses are neutralized and restoring forces are minimized;

polymer material, in particular polycarbonate, has lower intrinsic stability than steel. Therefore, within the framework of the invention, it has proven to be particularly advantageous if the polymer strip is supported between edges running parallel to the direction of movement, in the area of which individual deformation steps can also be located. Supporting the polymer strip between these edges may be accomplished by at least one belt conveyor. With this belt conveyor, the polymer strip is supported between the edges running parallel to the direction of travel and is moved in the direction of travel. It has proven to be particularly advantageous if the polymer strip is held at the top and bottom by means of suitable conveyors, thus guaranteeing the stability of the continuous forming process;

Instead of belt conveyors, other suitable conveyor devices or support devices for supporting the polymer strip can also be used.

The invention is not limited to the embodiment illustrated in the drawing. For example, extensions in the area of the edges of the door leaf segments can also be formed by glued or welded thickened edges. The stabilizing profiles 200 can be made of just one piece, so that the extended edges of the door leaf segments have to be pushed into the stabilizing profiles from the side. Instead of a guide system that has two guide rollers

- 9 043473 are adjacent to the limiting surfaces of the guide rib opposite each other, guide systems in which guide rollers are placed in a guide rail can also be used. Instead of guidance by means of guide rollers, non-contact magnetic guidance can also be used.
