If the stabilizing device has two receptacles spaced apart from one another in the door leaf movement direction for receiving the edge regions of adjacent door leaf segments facing toward one another, it has proven to be particularly useful if the upper receptacle in the closed position and the corresponding mouth are delimited by two receptacle parts that are detachably connected to one another. In this case, an upper edge of a door leaf segment can be pushed into the lower receptacle of the stabilizing device in a direction extending parallel to the stabilizing device. The door leaf segment can then be threaded into a guide device of the rolling door and the lower edge of the door leaf segment can then be connected to a stabilizing device arranged underneath by the lower edge of the door leaf segment first being placed against a bounding surface of the first receptacle part of the stabilizing device that delimits the mouth and then the second receptacle part being fastened to the first receptacle part in a direction extending perpendicular to the plane of the door leaf in order to form the receptacle for the lower edge region of the door leaf segment.

With regard to a possibly desired sealing function, it can be expedient if a sealing material is accommodated in at least one receptacle, preferably an upper receptacle of the stabilizing device, preferably in the region of the base of this receptacle. Additionally or alternatively, the sealing material can also be provided between the extension in the edge region of a door leaf segment and the mouth of the receptacle. With this arrangement, damping can be achieved in the course of the door leaf movement if the extension hits an edge of the opening. In this way, a slight tension can also be achieved between the stabilizing device and the door leaf segment, which is able to compensate for slight tolerances. A sealing material arranged between the extension and the mouth can hold the pane tightly in position and reduce or completely prevent any possible noise development when the door leaf segment moves relative to the stabilizing device. A corresponding sealing material can be placed in the receptacle of the stabilizing device or attached directly to the extension of the door leaf segment. This can be a sealing material that swells when moisture penetrates. Since in the region of the lower receptacles in the closed position hardly any moisture can penetrate into the receptacles, no sealing material is regularly required in these receptacles. As can be seen from the above explanations, the present invention is used with particular advantage in such doors in which at least one segment including a floating-mounted edge portion includes at least one pane which is formed at least in portions of a flexible and/or transparent material such as polycarbonate.

In terms of improving thermal protection, it has proven to be particularly advantageous if at least one door leaf segment including a floating-mounted edge region includes at least two panes spaced apart from one another in the door leaf thickness direction and extending approximately parallel to one another, of which at least one includes an edge region held on the stabilizing device and facing toward an adjacent door leaf segment, wherein at least one edge region of at least one pane is held floating on the stabilizing device in such a way that a relative movement of this edge region with respect to the stabilizing device is possible at least in the door leaf movement direction. This edge region can be held on the stabilizing device in a manner similar to that already described above. In this context, it has proven to be particularly advantageous if at least one stabilizing device includes two receptacles spaced apart from one another in the door leaf thickness direction, each for receiving an edge region of a pane of a door leaf segment.

In the embodiment of the invention just described, the panes of a door leaf segment are spaced apart radially from one another in the open position. They are moved into the open position along tracks that are radially spaced apart from one another and correspondingly deform differently. As a result, when the door leaf is moved into the open position, a brief collision may occur if the edge regions of the panes are designed identically and are received in identical receptacles of the stabilizing device. To remedy this deficiency, a particularly preferred embodiment of the invention provides that at least one edge region of the inner (outer) pane in the roll facing toward (away from) the roll axis is held with greater play in relation to the stabilizing device than the corresponding edge region of the outer (inner) pane facing away from (toward) the roll axis. For this purpose, the distance between the mouth of the receptacle for the edge region of the radially inner (outer) pane and the bottom of this receptacle in the door leaf movement direction can be greater than the corresponding distance of the receptacle for the edge region of the radially outer (inner) pane. In this way, a possible track difference (relative movement) can be compensated for by the different tracks of the individual panes.

The double pane arrangement described creates an air cushion. The resulting chamber can be closed in the region of the edges of the panes extending parallel to the door leaf movement direction. For this purpose, a filling material, which in one preferred embodiment of the invention can be made of a yielding material, such as an elastic muntin, can be provided in the region of at least one of the edges of at least one segment extending parallel to the door leaf movement direction, preferably between delimiting surfaces of the panes facing toward one another. Elastic pads, such as foams, can be used as filling material, which are glued in or fixed mechanically. The filling material also enables the necessary mobility when moving the door leaf into the open position and out of the open position. Additionally or alternatively, fan-like plastic elements can also be used as filling material, which are connected to one another like a hinge and can be clipped onto a pane.

The use of elastic pads or elastic compartment elements in door leaf segments with only one pane is also considered within the scope of the invention, in order to compensate for the offset between the pane and the reinforcement profile in the edge region. As a result, a seal can be implemented to the side part of the door. Since the door leaf segments of a door according to the invention are usually made transparent, at least in portions, it is particularly preferred within the scope of the invention if the filling material extends over 50% or less, in particular 20% or less, of the door leaf width in a direction extending parallel to the stabilizing devices, so that the transparency of the door leaf segments is only slightly impaired.

In terms of a desired thermal separation between door leaf inside (interior) and door leaf outside (exterior) it has proven to be particularly useful if at least one stabilizing device has at least two stabilizing elements that are spaced apart from one another in the door leaf thickness direction and are connected to one another via a connecting element made of thermally insulating material. Thus, when using stabilizing elements having sufficient strength, such as stabilizing elements made of steel or aluminum, satisfactory stabilization can be achieved without impairing the thermal separation.

In order to provide a door that enables high door running speeds, joint assemblies for guiding the door leaf movement are preferably provided in the region of the lateral edges of the door leaf, which in the closed position run at least in portions in the direction of gravity, and are fastened on the door leaf and can interact with corresponding fixed guide devices, such as guide rails, wherein each of the joint assemblies includes a plurality of joint members connected to one another with respect to joint axes extending perpendicular to the movement direction with the lateral edges of the door leaf, so that the door leaf is connected via the stabilizing devices to the joint assemblies. In this respect, the structure of doors according to the invention corresponds to the structure of the doors described, for example, in WO 2018/219512 A1. The content of the disclosure of this document with regard to the design of the joint assemblies and the guide rail as well as the coupling of the stabilizing devices to the joint assemblies is included in this description by express reference.

Corresponding to the known doors, at least one segment made of flexible material can also be arranged between two stabilizing devices in the case of rolling doors according to the invention, wherein a lateral edge of the segment extending approximately perpendicular to the stabilizing devices and the joint axes and approximately parallel to the joint assemblies and the door leaf movement direction can extend over two, three, or more joint members and at least one edge region of the segment can be held floating on a stabilizing device.

According to WO 2018/219512 A1, at least one stabilizing device can extend approximately parallel to a joint axis and be connected along this joint axis to at least two, preferably at least two, joint assemblies provided on mutually opposite lateral door leaf edges. To increase the overall stability of the arrangement, at least one reinforcement strip can be provided which extends approximately parallel to the lateral door leaf edge or the door leaf movement direction and is fastened to the door leaf. Similarly to the doors according to WO 2018/219512 A1, at least one possibly oval-spiral guide track can be provided to guide the door leaf movement and to determine the open position of the door leaf, wherein at least one joint member on its side facing away from the door leaf can include a guide assembly working together with the guide track to guide the door leaf movement, which preferably comprises at least one guide roller which is rotatably mounted with respect to a roller axis extending parallel to the joint axes and which is preferably accommodated in a guide track at least in the open position of the door leaf.

With regard to a simple adaptation of the structure of the door leaf of a rolling door according to the invention, it has proven to be particularly expedient if a stabilizing device extending parallel to a joint axis is only connected to the joint assemblies. This embodiment of the invention makes it possible to design the stabilization of the door leaf variably while the design of the individual door leaf segments or panes remains the same if the stabilizing device connected only to the joint assemblies can be attached to the joint assemblies independently of the dimensions of the individual door leaf segments. It is not fastened on the door leaf segments or panes. The attachment of this additional stabilizing device therefore does not require any adjustment of the geometry of the door leaf segments or panes. The variability of the attachment of this stabilizing device is only limited by the division of the joint members of the joint assembly.

If additional collision protection is to be provided for rolling doors according to the invention, the stabilizing device connected only to the joint assemblies can be arranged between the lower stabilizing devices and those connected to the panes of the rolling door. Within the scope of the invention, however, it has proven to be particularly expedient if the stabilizing device not connected to the door leaf segments is arranged between the 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 lintel region of the wall opening without having to change the geometry of the door leaf segments and the other components of the rolling door according to the invention.

In this context, it has proven to be particularly expedient if the stabilizing device, which is only connected to the joint assemblies but not to the door leaf segments, includes a sealing arrangement that can be placed against a lintel of the wall opening on its side facing away from the adjacent door leaf segment and/or on its side facing toward the segment includes at least one sealing strip which extends approximately parallel to the hinge axes, preferably over essentially the entire width of the door, and can be placed against the adjacent segment.

According to a particularly preferred embodiment of the invention, the leading edge of the door leaf during an opening movement can be formed by a leading stabilizing device which is connected in a rotationally-fixed manner to an upper edge of a segment made of a flexible material in the closed position and which is connected in a rotationally-fixed manner to a guide assembly. This arrangement prevents the door leaf segment from bulging out undesirably, as explained in detail in WO 2018/219512.

In order to obtain a tight guide seal, it has proven to be expedient if at least one joint member of a joint assembly is assigned a sealing assembly that can be placed against a bounding surface, in particular the inner bounding surface, of the door leaf in the closed position, as explained in detail in WO 2018/219512. Furthermore, within the scope of this invention, a pretensioning device that can be coupled in the course of the opening movement to a trailing edge of the door leaf during an opening movement and can be pretensioned in the course of the opening movement can also be provided for braking the opening movement and for providing a pretensioning force that displaces the door leaf from the open position into the closed position.

As can be seen from the above explanation, a door according to the invention expediently includes a guide device for guiding the door leaf movement between the open position and the closed position. The invention is used with particular advantage in such doors that allow a high door speed. For this purpose, the guide device can enable contactless magnetic guidance. For this purpose, the guide device can include a magnetic field generating device on the door leaf side and a magnetic field generating device that is fixed with respect to the wall opening, wherein the magnetic field generating devices are designed to obtain contactless guidance of the door leaf movement along at least one portion of the specified track in the region of at least one of the mutually opposite lateral edges.

Corresponding guide assemblies are described in PCT/EP2019/058221. The disclosure content of this document with regard to the guide devices and the magnetic field generating assemblies is hereby incorporated into this description by express reference. In this context, it is of particular importance that the guide assembly includes at least one guide web which is fixed with respect to the wall opening and extends along a portion of the specified track, having two outer bounding surfaces and at least two guide devices fastened to the door leaf, wherein a first outer bounding surface of the guide web a forms a guide surface for a first guide device and a second outer bounding surface of the guide web forms a second guide surface for a guide device, so that the guide web is received between the guide devices attached to the door leaf. Alternatively or additionally to the magnetic field generating devices, at least one guide device can include a guide roller which is rotatably mounted with respect to a roller axis extending perpendicular to the specified track and approximately parallel to the door leaf in the closed position, which rolls on a guide surface of the door leaf when the door leaf moves.

If contactless guidance of the door leaf movement with the aid of magnetic field generating devices is used, at least one magnetic field generating device, preferably at least one magnetic field generating device on the door leaf, can include at least one permanent magnet. The magnetic field generating device on the door leaf can expediently include two permanent magnets which are arranged on opposite sides of the guide web and are fixed to a common carrier which engages over an edge of the guide web on the door leaf. Further details of the magnetic field generating devices are explained in PCT/EP2019/058221, the content of the disclosure of which, also with regard to the magnetic field generating devices, is hereby incorporated into this description by express reference.

According to a further aspect, the invention relates to a method for producing a segmented pane for a rolling door according to the invention, which is essentially characterized in that a plastic web and/or board preferably consisting at least partially of polycarbonate is conveyed along a conveying direction, in particular is drawn off in a conveying direction continuously from one decoiler, or a winding or coil, at least one edge of the plastic web extending parallel to the conveying direction is bent over, if necessary with the aid of a roll former, and then a pane is severed from the plastic web along a separating line extending approximately perpendicular to the conveying direction. Thus, the panes for rolling doors according to the invention can be produced in a continuous manufacturing process. The roll former can be a double-head profiling system, for example. The plastic web can be delivered wound up in a spiral on a decoiler reel and supplied to the manufacturing process and/or delivered in the form of rectangular blanks and supplied to the manufacturing process.

DETAILED DESCRIPTION

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.

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.

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.

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.

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
