DETAILED DESCRIPTION

[0066] FIG. 1 shows two door leaf segments 110 and 120 of a door leaf 100 of a door according to the invention, arranged one behind the other in the door leaf movement direction indicated by the double arrow P. The door leaf segments consist at least partially of a flexible material and form bending regions of the door leaf. At least one door leaf segment, preferably each door leaf segment, can be provided with a functional film on at least part of its outer bounding surface. A stabilizing device designed as a stabilizing profile 200 is arranged between the door leaf segments 110 and 120. The stabilizing profile 200 extends in a direction perpendicular to the door leaf movement direction P, approximately in the plane of the door leaf. A lower edge of the upper door leaf segment 120 that is provided with a functional film is held floating in the region of an upper receptacle 230 (cf. FIG. 2) of the stabilizing profile 200, while an upper edge of the lower door leaf segment 110 that is also provided with a functional film is held floating in a lower receptacle 240 (cf. FIG. 2) of the stabilizing profile 200. An upper edge of the door leaf segment 120 is held on a further stabilizing profile 200, just as a lower edge of the door leaf segment 110 is also held on a lower stabilizing profile 200.

[0067] The stabilizing profiles 200 are fastened to a joint assembly 300 which extends approximately parallel to the door leaf movement direction or parallel to a lateral edge of the door leaf 100. The joint assembly 300 comprises a plurality of joint members 310 which are arranged one behind the other in the door leaf movement direction and are connected to one another in an articulated manner with respect to joint axes extending perpendicular to the door leaf movement direction. In this case, three joint members 310 are arranged between each two adjacent stabilizing profiles 200. In other embodiments of the invention, only one or two or four or more joint members can also be provided between the stabilizing profiles 200. A stabilizing profile can also be provided in the region of each connection between successive joint members.

[0068] On its side facing away from the door leaf segments 110 and 120, the joint assembly has guide rollers 320, which are rotatably mounted with respect to roller axes extending parallel to the joint axes. The guide rollers 320 are each arranged in pairs in the region of a joint axis in such a way that they can receive a guide web between them and can roll on mutually opposite bounding surfaces of the guide web in order to enable the door leaf movement to be guided, as described in PCT/EP2019/058221.

[0069] As can be seen particularly clearly in FIG. 2, an upper edge region 112 of the door leaf segment 110 extending parallel to the hinge axes and parallel to the stabilizing profile 200 is arranged in a receptacle 240 of the stabilizing profile 200. The upper edge 112 of the door leaf segment 110 is formed by bending over the upper edge of the door leaf segment 112 onto itself as an extension in a plane perpendicular to the door leaf plane defined by the door leaf movement direction P and the stabilizing profile 200. Starting from the extension 112, the door leaf segment 110 extends downwards with a transition region through a mouth 250 of the stabilizing profile 200 and is exposed outside the mouth 250, as can be seen in FIG. 1. The door leaf segment 120 also includes an extension 122 received in a receptacle 230 of the stabilizing profile 200. Starting from the extension 122, the door leaf segment 120 extends upwards through a mouth 225 with a transition region and is exposed outside the mouth 225.

[0070] The mouth 250 is delimited by bounding surfaces 232 and 242, the distance of which from one another in a direction parallel to the door leaf thickness direction 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 exposed region outside of the stabilizing profile 200. The mouth 225 is also delimited by bounding surfaces 212 and 222, the distance between which in the door leaf thickness direction is less than the thickness of the extension 122, but greater than the thickness of a transition region between the extension 122 and the region of the door leaf segment 120 that is exposed outside of the stabilizing profile 200.

[0071] As can also be seen in FIG. 2, the stabilizing profile 200 is made in two parts from two parts 210 and 220 which are detachably connected to one another. The recess 240 at the lower edge of the stabilizing profile 200 is formed entirely by the first stabilizing profile part 210, while the receptacle 230 at the upper edge of the stabilizing profile 200 is formed by the two stabilizing profile parts 210 and 220. A first bounding surface 212 of the mouth 225 is formed by the first stabilizing profile part 210, while a second bounding surface 222 of the receptacle 230 is formed by the second stabilizing profile part 220.

[0072] To install a rolling door of the type shown in the drawing, an upper edge of a door leaf segment can be pushed into the receptacle 240 in a direction extending parallel to the stabilizing profile 200, wherein a transition region between the extension 240 and an region of the door leaf segment that is exposed outside of the stabilizing profile 200 penetrates the mouth 250. The module prepared in this way can be threaded into a guide device, which can consist of a guide web arranged between the guide rollers 320. A lower edge 122 of the door leaf segment can then be placed against a bounding surface 212 of the first stabilizing profile part 210 and the second stabilizing profile 220 can be clipped onto the first stabilizing profile 210 to form the mouth 225, which is penetrated by the transition region between an extension of the door leaf segment received in the receptacle 230 and an region of the door leaf segment that is exposed outside of the stabilizing profile 200.

[0073] The distance between the mutually opposite bounding surfaces 212 and 222 or 232 and 242 of the mouths 225 or 250 is greater than the thickness of the transitional regions penetrating these mouths. This prevents a clamping effect in the region of the transition regions.

[0074] Furthermore, the distance between the mouth 225 or 250 and the bottoms of the receptacles 230 and 240 opposite to the corresponding mouths 225 or 250 is greater than the length of the extensions 122 or 112 in the door leaf movement direction. This enables a relative movement of the door leaf segments 110 and 120 with respect to the stabilizing profile 200.

[0075] A sealing material can be arranged in the region of the bottom of the receptacle 230, which possibly swells if moisture penetrates.

[0076] The embodiment of the invention shown in FIG. 3 differs essentially from the embodiment explained with reference to FIG. 2 in that a damping element 230 is arranged between the bent-over lower edge of the pane 120 forming the extension 122 and the lower bounding surface of the part 220 of the stabilizing profile 200, which, on the one hand, causes a sealing of the pane 120 floating in the stabilizing profile 200, and, on the other hand, provides a pre-tension of the pane 120 mounted floating in the stabilizing profile 200, which helps to compensate for tolerances and holds the pane 120 tautly in its position. Furthermore, the damping element 140 reduces noise development, which can occur when the bent-over lower edge of the pane 120 is moved in the receptacle 230 and strikes against the lower bounding surface of the part 220 of the stabilizing profile.

[0077] The embodiment of the invention shown in FIG. 4 differs essentially from the embodiment of the invention shown in FIGS. 1 and 2 in that the door leaf segments include two panes 120a and 120b or 110a and 110b extending essentially parallel to one another, which are each designed as flexible polycarbonate panes. The lower edges of the panes 120a and 120b are each provided with an extension formed by bending over these edges, which are mounted floating in receptacles 230a and 230b of the stabilizing profile 1200. The upper edges of the panes 110a and 110b of the lower segment are held in receptacles 240a and 240b of the stabilizing profile 1200. An air cushion 180 promoting heat protection is formed between the panes 120a and 120b or 110a and 110b. The air cushion 180 is closed at the edges extending parallel to the movement direction P of the segments 120 and 110 by elastic cushions 190 provided between the panes 120a and 120b or 110a and 110b. These cushions 190 can be designed as elastic muntins. For example, elastic pads made of a foam-like material can be used, which are glued in or fixed mechanically. The elastic design of the cushions 190 also enables the necessary mobility when winding the door leaf into the spiral-shaped guide track when the open position is reached.

[0078] Additionally or alternatively, fan-like plastic elements, which are connected to one another like a hinge, can also be clipped onto the pane in the chamber 180. The use of corresponding elastic pads or elastic compartment elements in door leaf segments with only one pane, as shown in FIGS. 1 and 2, is also considered in order to compensate for the offset between the pane and the stabilizing profile in the wall region. As a result, the sealing of the door leaf can be improved in the closed position.

[0079] The embodiment of the invention shown in FIG. 5 differs essentially from the embodiment explained with reference to FIG. 4 in that the chamber 2230b of the stabilizing profile 2200, which is used to receive the extension 230b at the lower edge of the pane 110b, has a greater depth in the door leaf movement direction than the chamber 230a which is used to receive the extension 122a formed at the lower edge of the pane 110a. As a result, the pane 110b lying radially on the inside in the open position is mounted with greater play in the receptacle 230b than the pane 110a lying radially on the outside in the open position. As a result, the different deformation of the panes 110a and 110b when the door leaf has reached the open position can be compensated for, as illustrated in FIG. 5b.

[0080] The embodiment of the invention shown in FIG. 6 differs essentially from the embodiment of the invention explained with reference to FIG. 5 in that the stabilizing profiles 3200 are made in three parts overall, wherein the parts 3210, 3220, 3230 are made in succession in the door leaf thickness direction. The part 3210 lying on the inside when the door leaf is in the closed position, like the part 3220 of the stabilizing profile 3200 lying on the outside in the closed position, is made of a metallic material. This gives the stabilizing profile the necessary stability. The parts 3210 and 3220 are connected to each other via connecting elements 3230 made of thermally insulating material such as plastic. Thus, while ensuring sufficient overall stability of the stabilizing profiles 3200, a heat loss between the interior and the exterior via the stabilizing profiles 3200 can be effectively reduced.

[0081] The embodiment of the invention shown in FIG. 7 differs essentially from the embodiment of the invention shown in FIGS. 1 and 2 in that a stabilizing profile 400 is provided between the stabilizing profiles 200 fixed to the lower and upper edges of the panes 110, 120, which is fastened solely on the joint members of joint assembly 300. This additional stabilizing profile 400 can be positioned independently of the pane geometry and attached to position a lintel seal depending on the height of the wall opening. For this purpose, the stabilizing profile 400 is provided with a sealing element 410 on its side facing away from the panes 110, 120, while it is embodied having hose seals 420 on the side facing toward the pane 120, which press against the pane 120. Since the additional stabilizing profile 400 is not fastened on the pane 120, it can be attached to any joint members 310 independently of the pane geometry. The position of the seal 410 can thus be adjusted to the height of the wall opening. This not only improves the sealing effect, but also increases the overall stability of the rolling door.

[0082] In FIG. 8, a plant for the production of panes for the door leaf segments of rolling doors according to the invention is shown schematically. When using the plant shown in FIG. 8, a plastic web consisting at least partially of polycarbonate is continuously unwound as coil goods from an unwinding reel 510 in a conveying direction F. A functional film is laminated onto the plastic film using a laminator that is not shown in the drawing. The plastic web runs through a trimming unit 520, in which the exact width of the plastic web is set, and then a double-head profiling system 530, in which the edges of the plastic web extending parallel to the conveying direction F are bent over to create the extension of the panes. As can be seen in FIG. 8, the profiling system has a large number of shaping rollers, using which the edges of the material web are bent over step by step. After leaving the double-head profiling systems 530, panes of a predetermined length are cut off the material web with the aid of a separating unit 540 along a separating line extending perpendicularly to the conveying direction F and placed on an outfeed table 550. The following features of methods according to the invention are of particular importance in the scope of this invention. They can be essential to the invention individually or in combination with one another: [0083] The plastic web is produced by extrusion and wound up into a coil or roll. The width of the plastic web or the coil width results from the size of the extruder. [0084] The width of the extruded plastic sheet, such as an extruded polycarbonate sheet, will vary. Using a trimming station, the material web can be precisely trimmed to the desired width, preferably before it enters the forming station. [0085] In the trimming station, a wider plastic web can be split to a narrower size. This allows the required pane size to be set depending on the door size. [0086] A plastic web, in particular a polycarbonate web, can have significantly higher restoring forces than steel after passing through a forming device, which may be designed as a double-head profiling system. Therefore, when the method according to the invention is carried out, there is preferably a significant overbending in order to ultimately obtain the desired contour. It is also taken into consideration that the deformation can continue to revert over time and that the deformed state can only slowly leave the shape obtained after leaving the deformation station under the influence of the restoring forces. [0087] To reduce the restoring forces, it has proven useful to assist the forming process with heat. When using polycarbonate webs, the webs are expediently heated to a temperature of between 150 and 170 degrees Celsius, at least in the forming region. This achieves the following effects: [0088] 1. There is gentler forming with less stress on the polycarbonate and thus avoidance of crack formation in the forming region. [0089] 2. The forming stresses are neutralized and the restoring forces are minimized. [0090] Plastic, in particular polycarbonate, has less inherent stability than steel. It has therefore proven to be particularly expedient within the scope of the invention if the plastic web is supported between the edges extending parallel to the conveying direction, in the region of which the individual forming stages can also be arranged. The plastic sheet can be supported between the edges by means of at least one belt conveyor. Using the belt conveyor, the plastic web is supported between the edges extending parallel to the conveying direction and conveyed in the conveying direction. It has proven to be particularly expedient if the plastic web is held from above and from below with the aid of suitable conveyors, in order to ensure stability for a continuous shaping process. [0091] Instead of belt conveyors, other conveyor devices or support devices suitable for supporting the plastic web can also be used.

[0092] The invention is not limited to the exemplary embodiment explained on the basis of the drawing. For example, the extensions in the region of the edges of the door leaf segments can also be formed by a welt that is glued or welded on. The stabilizing profiles 200 can be made in one piece overall, so that the extended edges of the door leaf segments have to be pushed into the stabilizing profiles laterally. Instead of a guide assembly in which two guide rollers press against mutually opposite bounding surfaces of a guide web, guide assemblies can also be used in which guide rollers are received in a guide rail. Instead of guiding by means of guide rollers, a contactless magnetic guide can also be used.

[0093] The functional films used according to the invention can also include so-called low-E films having a high degree of reflection. As a result, good thermal insulation can be achieved with a comparatively small pane thickness. Of course, the stabilizing devices of the doors according to the invention can also be covered with film in order to enable a uniform door leaf design.
