Description

The invention relates to a door, in particular a roller door, with a between an open position in which it at least partially exposes a wall opening and optionally forms a multi-layer winding above the wall opening, and a closed position in which it at least partially closes the wall opening, along a Movable path of movement and at least in sections designed as a web-shaped curtain made of flexible material, the web-shaped curtain being assigned a stabilizing device extending transversely, in particular approximately perpendicular, to the movement path, which at least in the closed position causes a deformation of the curtain into a perpendicular to one through the movement path and the stabilization device counteracts the closing plane extending in the direction of the load.

Roller doors of this type are used in particular to close hall entrances. In this case, the closing element, which is designed as a door leaf, can be wound up on a winding shaft arranged above the hall entrance during a transition from the closed position to the open position. This ensures that the door leaf can be accommodated in a space-saving manner in the open position. For this purpose, the door leaf can be formed in the form of a so-called lamellar armor with a multiplicity of lamellae that are articulated to one another and which run perpendicular to the direction of movement of the closing element. In cases where a break-in-proof closure of the driveway is less important than a quick opening and closing movement to open and close the driveway, the closing element can at least partially also be in the form of a sheet-like curtain, for example made of PVC, which consists of several hanging segments that are subdivided in the direction of the web and connected to one another can be formed.

The high-speed roller doors with a closing element or door leaf in the form of a web-shaped curtain, possibly formed from several interconnected curtain segments, must meet various, sometimes conflicting requirements. On the one hand, the roller shutters must have a certain stability transversely to the direction of movement or transversely to the flat extension of the curtain in the closed position in order to be able to withstand external influences such as wind loads, which can lead to a bulging of the curtain. Furthermore, it has proven to be advantageous if the individual curtain segments forming the curtain are detachably connected to one another, because simple dismantling of the curtain and replacement of individual curtain segments are possible in the event of damage, repair and / or maintenance. Such roller doors are, for example, in the international publication WO 2018 / 219512A1 described. The individual curtain segments are releasably attached to one another via a connecting device consisting of stabilizing profiles designed as extruded aluminum profiles and welts that engage with the extruded aluminum profiles. While the required stability, especially against wind loads, as well as a simple dismantling option are achieved, the extruded aluminum profiles require a reduction in the running speed of the roller doors and an increased noise level when the curtain is rolled up and down. This is because it has been found that the extruded aluminum profiles hit against the winding shaft when being wound onto the winding shaft and when it is being unwound from the winding shaft, creating an out-of-round door travel.

In the prior art there are also roller shutters in which the curtain segments are permanently attached to one another, in particular by welding, or the curtain is made from one piece. With roller doors of this type, the required stability against external influences, such as wind loads, can be achieved by providing the curtain with stabilizers, such as flat spring steel sheets. Rolling doors formed in this way are characterized by excellent running properties and speeds without causing annoying winding noises. The disadvantage of such roller shutters is, among other things, that in the event of damage, repair and / or maintenance, even with minor damage to the one-piece curtain or damage to only individual curtain segments, the complete curtain usually has to be replaced, which leads to high labor and Costs leads. It is not possible to dismantle or replace individual curtain segments.

It has been found that, despite the high running speeds of the roller doors, so-called collision damage is generated if a vehicle, for example a forklift, drives against the curtain during the opening movement of the curtain or in the closed position and damages it. Usually, the curtain is damaged in one of the lower edge areas in the closed position. Furthermore, the approach of the curtain, for example by a vehicle, can lead to cracks forming in the curtain made of a flexible material and / or the guide elements used to guide the movement of the curtain being damaged.

In view of these described problems in the prior art, in WO 2004/088080 A1 proposed that arranged in the closed position at the lower edge of the closing element Design stabilization element elastically deformable so that it can convert at least part of the impact energy into deformation energy. Furthermore, in order to increase the operational reliability of the gates, at least one guide device interacting with the guide element is arranged on at least one side edge of the closing element, which guide device is designed to be released from the guide element when a vehicle hits the closing element in order to prevent damage to the curtain, to avoid the guide element or the guide device. In order to further ensure reliable guidance of the movement of the closing element, an inlet arrangement can be arranged on the upper edge of the guide element, with which the guide element can be automatically inserted into the guide element when the closing element is closed. The inlet arrangement can according to the WO 2004/088080 A1 can be combined with a pretensioning device with which the closing element or the stabilizing element is urged into directions opposite one another and running transversely to the direction of movement of the closing element. As a result, the lower edge of the closing element can be centered in order to ensure reliable introduction of the lower edge of the closing element into the guide elements even at high closing speeds.

Both the elastically deformable stabilizing elements on the lower edge of the closing element and the inlet arrangements for the guide members, which are provided with pretensioning devices, reduce the consequences of damage when vehicles hit the closing elements. Nevertheless, the collisions with vehicles continue to lead to unacceptable damage to the closing elements and / or the guide elements, in particular if the closing elements are formed from a curtain made of an elastically flexible material. On the one hand, neither the flexibility of the stabilizing element nor the releasable connection of the closing element or guide device and guide element and their reliable insertion into one another are sufficient to rule out damage to the closing element and / or the guide elements. On the other hand, the gates known in the prior art have not yet been able to solve the problem that the complete curtain always has to be replaced in the event of damage to one-piece hangings or hangings made of hanging segments that are permanently attached to one another.

In view of these problems in the prior art, the object of the invention is to improve a generic door, in particular to provide a door that enables high running speed and wind stability while at the same time ensuring simple repair and maintenance.

The object is achieved by the subject matter of the independent claim.

According to this, a door, in particular a roller door, comprises one between an open position in which it at least partially exposes a wall opening and, if necessary, forms a multi-layer winding above the wall opening if it is designed as a roller door, and a closed position in which it at least opens up the wall opening partially closed, movable along a movement path and at least in sections designed as a web-shaped curtain made of flexible material. The movement path can be divided into a movement path section oriented essentially in the vertical direction, along which the door leaf moves when it at least partially closes the wall opening, and into a movement path section inclined with respect to the vertical direction, which is for example oriented essentially in the horizontal direction and along which those door leaf sections move which do not close part of the wall opening. Alternatively, if the door is implemented as a roller door, the door leaf can be rolled up above the wall opening to form a multilayered roll, so that the movement path section adjoining the vertical path section is formed in a spiral shape. The path of movement of the door leaf can be predetermined, for example, via guide devices arranged on the side edges of the door leaf, which interact with guide elements, such as guide rails, arranged on the wall delimiting the wall opening, in order to guide the door leaf during the opening and closing movement. The curtain can furthermore have a rigid lower part, in particular forming the lower edge section of the curtain in its closed position, for example made of metal such as steel or aluminum, for example if increased wind stability is required.

The web-shaped curtain is assigned a stabilizing device extending transversely, in particular approximately perpendicular, to the path of movement, which counteracts deformation of the curtain in a load direction perpendicular to a closing plane spanned by the path of movement and the stabilizing device, at least in the closed position. The stabilization device can usually be made rigid and / or made of aluminum or metal. The execution of the door leaf at least in sections from flexible material enables a reduction of the space requirement because the material adapts itself to the roll to be formed in the open position and thus enables a small spiral diameter in the open position. At the same time, the Stabilization device realized a robust door leaf. In this context, it is possible for the door leaf to be guided along the path of movement with the aid of a guide arrangement and / or articulation arrangement coupled to the stabilization device, as shown in FIG WO 2018/219512 A1 , the contents of which are fully incorporated herein by reference. Commercially available, preferably transparent or colored, PVC and / or polycarbonate can be used as the flexible or resilient material for the production of door leaves according to the invention. The door can be adapted to the relevant requirements or circumstances via the thickness of the plastic sheet. The resilience or flexibility ensures a small winding radius for space-saving accommodation of the curtain in the closed position. In particular, polycarbonate has proven to be a material with excellent properties for use in doors according to the invention. The material has high elasticity with sufficient flexural rigidity to follow the winding contour even with large widths. The material also has other positive properties such as high impact resistance.

According to the invention, the web-shaped curtain has at least two curtain segments following one another in the direction of the movement path, which are releasably connected to one another along at least one nominal dividing line extending in the closing plane, preferably approximately perpendicular to the movement path, in such a way that the facing edges of the curtain segments remain deformable. Detachable in the sense of the present invention is to be understood to mean that the connection of the hanging segments can be released or separated, in particular by hand, without damage to components of the door, in particular the connected hanging segments. The nominal dividing line can be an imaginary axis in the area of the fastening zone between the two hanging segments. For example, the nominal dividing line can be arranged in relation to the movement path, in particular centrally, between the mutually facing edges of the path segments to be connected.

The conflict of interest on which the present invention is based can thus be resolved from a high running speed and high wind stability on the one hand and a simple repair and maintenance option on the other. Because the facing edges of the curtain segments remain deformable, there is a resilience with respect to the forces acting upon the impact of a vehicle, which reduces the risk of damage to the curtain. The releasable connection of the hanging segments can be designed free of rigid fastening or connecting profiles. A decisive development idea is the functional separation of the stabilization of the curtain, which is created by the stabilization device, and the attachment of the curtain segments to one another, which is done by the detachable connection. If the curtain is damaged, it is no longer necessary to replace the entire curtain. The possibility is created by releasing the connection of the hanging segments to replace individual hanging segments in a simple and inexpensive and easy-to-assemble manner.

In an exemplary embodiment, a curtain segment forming the lower edge of the curtain is connected to a curtain segment trailing in the opening movement. Furthermore, a stabilizing device can be arranged at the lower edge of the hanging segment forming the lower edge of the hanging. The stabilization device can according to the WO 2004/088080 A1 be designed, the content of which is fully incorporated herein by reference.

In a further exemplary embodiment, the door comprises an at least partially deformable, in particular elastically deformable, connecting device for releasably connecting the mutually facing edges of the hanging segments. In particular because the connecting device does not necessarily have to contribute to increasing stability, it can be designed to be elastically deformable and flexible, in contrast to the rigid stabilizing device, which is usually made of aluminum or metal. The connecting device can extend over the entire width of the curtain oriented transversely to the movement path and can fasten the curtain segments to be connected to one another over its entire width. The elasticity of the connecting device has the advantage that the connecting device can be deformed back to its original shape after a deformation, for example due to a collision with a forklift truck, so that the curtain can on the one hand continue to close the wall opening cleanly and on the other hand reliably along the Movement path is movable, in particular in the open position can also be wound into a roll. According to an exemplary development of the door according to the invention, the connecting device consists exclusively of an elastically deformable material, in particular an elastomer material and / or of plastic. For example, the materials PVC, in particular hard PVC, PE, EPDM, SBR and silicone, are suitable.

In a further exemplary embodiment of the door according to the invention, the connecting device is designed in such a way that a curtain segment forming the lower edge of the curtain and a further hanging segment can each be releasably fastened or fastened thereto. Because the connecting device can be detachably connected to the two hanging segments to be connected, it is not only possible to easily replace the hanging segments in the event of damage and / or maintenance, but also to replace the connecting device itself with little assembly effort when it needs to be replaced. The detachable fastening can be implemented by a form fit, which is characterized in particular by the fact that simple assembly and disassembly of the curtain segments or the connecting device is ensured.

According to a further exemplary embodiment of doors according to the invention, the connecting device has two receptacles, each assigned to one of the hanging segments to be connected, for positively receiving one of the mutually facing edges of the hanging segments. For example, the connecting device has a receptacle assigned to an upper edge of the curtain segment forming the lower edge of the curtain and a receptacle assigned to the lower edge of the curtain segment trailing in the closing movement direction. The edges can have thickenings, for example in the form of a bead or a welt. The interlocking engagement between the edge and the receptacle can be implemented, for example, in the manner of a welt rail.

According to an exemplary development, the receptacles are made from one piece with one another. For example, the receptacles, in particular the connecting device, can be produced in a plastic injection molding process, a plastic extrusion process or in a foaming process. In this way, inexpensive manufacturing processes suitable for mass production can be used. The receptacles can each have a guide groove extending in the longitudinal direction of the receptacles, which when mounted on the curtain is oriented transversely to the path of movement of the door leaf, in particular with a constant cross-section in the direction of the nominal dividing line, for inserting the edges of the curtain segments. The edges are inserted in the longitudinal direction of the guide grooves. Furthermore, the receptacles can each have a longitudinal opening oriented in the direction of the path of movement of the door leaf for sections of the curtain segments adjoining the edges or for connecting means coupled to the curtain segments. This means that the edges are either produced or formed in one piece with the respective hanging segments or are part of separate connecting means which are in particular coupled with the hanging segments in a materially bonded manner. Furthermore, the longitudinal openings can have a clear width in the load direction which is smaller than the maximum dimensions of the thickenings received in the receptacles in this direction. The design of the receptacle with a guide groove and longitudinal opening enables simple assembly for the form-fitting coupling of the connecting device to the curtain segments and also simple dismantling. In this way, even inexperienced operating personnel can replace a damaged curtain segment and / or the connecting device in the event of damage and / or maintenance. On the other hand, the positive coordination of the guide groove and the edge provides a predefined assembly or disassembly direction, so that simple assembly or disassembly is guaranteed and incorrect assembly can be avoided. In addition, the edges are guided into the guide grooves in the receptacle during insertion in the longitudinal direction. Because of the interlocking interlocking, the connecting device can be pulled or pushed onto the hanging segments in a simple manner without tilting or jamming with the hanging segments.

In a further exemplary embodiment of the door according to the invention, the connecting device is designed such that at least one of the, in particular both, curtain segments is released in the event of a load acting on the curtain that exceeds a predetermined load limit in the load direction. This embodiment of the door leaf is based on the knowledge that collision damage or collisions with forklifts, for example, often result in damage to the curtain in the area of the fastening interface between the curtain segment and the connecting device. This configuration of the door leaf is particularly noticeable when high loads act, for example at high speeds of the object causing the collision, such as the forklift truck. Because the connecting device releases at least one of the hanging segments as soon as the acting load exceeds a predetermined load limit, the connecting device is equipped with damage protection. In other words, the fastening interface between the hanging segment and the connecting device forms a predetermined separation point, so that the fastening, in particular the form-locking engagement, between the hanging segment and the connecting device is released when the load is too high. As a result, protection against damage is achieved while accepting an at least partial, in particular automatic, dismantling of the door leaf. The edges of the hanging segments can be matched to a dimension of the longitudinal openings of the receptacles of the connecting devices so that when the predetermined Load limit the edges can be pushed through the longitudinal openings, at least in sections, using the elastic flexibility of the connecting device and / or the edges themselves and can get out of the guide grooves. For example, the load limit is around 20 kg / m. The releasable connection between the curtain segments, in particular the connecting device, is preferably designed in such a way that, in the event of a load, damage to the curtain segment trailing in the closing movement direction is avoided. Under certain circumstances, this can be done with the acceptance of damage to the curtain segment leading in the closing direction of movement, in particular forming the lower edge of the curtain.

In a further exemplary embodiment of goals according to the invention, the cross-section of the connecting device in a sectional plane running perpendicular to the longitudinal direction is symmetrical with respect to an axis oriented in the direction of movement, in particular a vertical central axis, and / or with respect to an axis oriented parallel to the nominal separation line, in particular a horizontal central axis. Due to the double axis symmetry, the connecting device has a geometry that is easy to manufacture. Furthermore, assembly is made easier because the orientation of the connecting device in relation to the curtain is not important. For example, the connecting device can have a double C shape in cross section. Furthermore, the connecting device can have a connecting web connecting the receptacles, which is made in particular from one piece with the receptacles, through which the horizontal axis of symmetry runs.

According to an exemplary development, the connecting device is arranged in the closed position at a distance in the range of 250 mm to 1,250 mm from the floor. Because the curtain is usually damaged at a lower edge area in the closed position, it is advantageous to arrange the connecting device at a vertical level so that such collision damage is largely possible by simply replacing the lower curtain segment, possibly including the connecting device. For example, the connecting device is located at a distance in the range from 350 mm to 1,000 mm or up to 500 mm from the floor.

In a further exemplary embodiment, the connecting device is designed as a double welt rail. It has been found that this known, advantageous fastening technique can also be used to satisfactorily connect two hanging segments.

According to a further exemplary embodiment, two further hanging segments that follow one another in the direction of the movement path are permanently connected to one another, in particular glued and / or welded. The door leaf can be designed in such a way that, with the exception of the hanging segment forming the lower edge of the hanging, all hanging segments are permanently connected to one another. As a result, the rigid extruded aluminum profiles used in the prior art for connecting curtain segments, which have had a negative effect on the running speeds of the doors, can be dispensed with. Furthermore, the production of door leaves according to the invention is also facilitated.

According to an exemplary development of the present invention, the curtain segments are connected to one another in such a way that they can only be released from one another when a securing device has been released. In this context, the releasability of the hanging segments in the direction of the intended separation line is meant. The deformability of the hanging segments and their releasability from one another in the load direction can be maintained. For example, the connecting device can be assigned a securing device for preventing a relative movement of the hanging segments in the direction of the nominal dividing line or for preventing the hanging segments from moving away from one another in the direction of the nominal dividing line. A securing device, such as an end cap or securing cap, can be arranged at at least one lateral end of the connecting device, in particular at both lateral ends of the connecting device, which is detachably connected to the connecting device and / or one of the hanging segments, in particular screwed, latched or is jammed. The safety device can, for example, be shaped and / or dimensioned in such a way that it overlaps the safety device on at least one side in the direction of the movement path and can optionally be placed against a lateral edge of the curtain.

In a further exemplary development of the gate according to the invention, the securing device is positively connected to the connecting device. The form fit can be such that the securing device overlaps the connecting device in the load direction. For example, the securing device has a receiving recess which is matched to the shape of the connecting device and in which a lateral end of the connecting device can be received, in particular in a clamping manner. The securing device can be designed to act to increase stability in the lateral edge region of the connecting device. For example, the securing device in the lateral edge region of the Connecting device counteract deformation of the securing device in the load direction. In this respect, the securing device can take on a double function, namely avoiding a relative movement of the curtain segments in the direction of the nominal dividing line and reducing or avoiding deformation of a lateral edge area of the securing device in the load direction.

According to an exemplary development, the connection device is provided with at least one, in particular with at least two, three or four, fastening bores for receiving fastening means, such as screws, clips or the like, for fastening the securing device and connection device to one another. Furthermore, it is possible for the securing device to be free of direct attachment to the hanging segments, but rather to be coupled to the hanging segments only indirectly via the connecting device. This can be advantageous, for example, because in the event of severe overloading, a complete separation of the hanging segments from one another can be guaranteed in order to avoid possible damage to the hanging segments.

In an exemplary embodiment of the present invention, the restoring force counteracting a deformation of the connecting device in the load direction is smaller than the restoring force counteracting a deformation of the stabilization device in the load direction. As a rule, the load direction points in the space to be closed by the door leaf or in the opposite direction. As a result, the consequences of damage as a result of a collision with a forklift truck, for example, can be further reduced, since the curtain is able to convert a larger proportion of the kinetic energy into deformation energy without causing damage such as cracks, especially at the connection points between the curtain and the connecting device .

According to a further exemplary embodiment, the door according to the invention has at least one guide device arranged on a lateral edge of the door leaf, by means of which the door leaf is guided during a movement in the closing plane. Furthermore, the door can have an inlet arrangement arranged on the upper edge of the guide device, with which the lateral edge of the door leaf can be automatically introduced into the guide device during a closing movement. Regarding the inlet arrangement, refer to the WO 2004/088080 A1 , the content of which is incorporated herein by reference. In particular, the inlet arrangement at the upper edge of the guide device has at least two opposing boundary surfaces of the door leaf and / or a stabilizing element arranged on the lower edge thereof, with which the door leaf or the stabilizing device runs in opposite directions and transversely to the path of movement of the door leaf is pushed.

In a further exemplary embodiment, the curtain segment leading along the movement path during a shooting movement, in particular forming the lower edge of the curtain, has an optical indicator which is optically different from the adjacent curtain segment. In this way, increased attention can be drawn to people who want to pass through the gate with vehicles such as forklifts, for example. Furthermore, increased visibility is achieved, especially in the dark, so that possible damage can be prevented. For example, the optical indicator can be a coloring or color of the hanging segment, an imprint or some other type of indicator applied, for example glued, to the hanging segment. The optical indicator can have a higher degree of reflection than the adjacent hanging segment. Furthermore, the visual indicator can be designed as a yellow or red warning bar, for example, in order to provide an additional visual indication of a possible danger point.

In the following description of exemplary embodiments of the present invention, a door according to the invention is generally given the reference number 1 Mistake. In the accompanying figures is the gate according to the invention 1 for example designed as a roller door, the door leaf 5 in the form of a sheet-shaped curtain 3 is formed and between an in 3 shown closed position in which it closes a wall opening, and an open position in which the door leaf 5 can be wound or wound up to form a multilayer roll, along a predetermined movement path R. can be moved.

Referring to the 1 and 2 is an exemplary embodiment of a connecting device 7th for detachable fastening of the lower edge of the hanging 3 forming curtain segment 9 with an adjacent hanging segment 11 , which when opening the lower curtain segment 9 running after, described. The connecting device 7th is in the 1 until 3 realized as a double welt rail, which is made of an elastically deformable or flexible material and made of one piece. The connecting device 7th has two identically designed, each one of the hanging segments 9 , 11 assigned recordings 13th , 15th each with a guide groove 17th , 19th and one in the longitudinal direction of the connecting device 7th extending longitudinal opening 21 , 23 are equipped. Looking at the 3 it can be seen that the longitudinal extension direction of the connecting device 7th when installed on the curtain 3 across, especially perpendicular, to the path of movement R. of the door leaf 5 is oriented in an opening and closing movement. The longitudinal direction of the connecting device 7th in the assembled state, which also defines the nominal dividing line, is also referred to below as the width direction B. designated.

In the in 2 illustrated sectional view of the connecting device 7th it can be seen that the connecting device 7th in the longitudinal direction or in the width direction B. has a constant cross section along its entire length. Furthermore, the exemplary embodiment is the connection direction 7th according to the 1 until 3 designed with double-axis symmetry in cross-section. As in 2 can be seen is the connecting device 7th axially symmetrical with respect to one in the direction of the web direction R. oriented vertical center axis Mv formed. In addition, the connecting device 7th axially symmetrical with respect to one, through one of the two C-shaped receptacles 13th , 15th connecting web 25th horizontal central axis running parallel to the nominal dividing line M _H educated.

The advantage of the gate according to the invention 1 lies, among other things, in the elasticity of the connecting device 7th as well as in the form-fitting connection option provided between the lowermost hanging segment 9 and the hanging segment arranged above it in the closed position 11 . The assembly of the individual curtain segments 11 , 9 with the connecting device 7th takes place in each case according to the following principle: The connecting device 7th , especially their recordings 13th , 15th , is designed to be open on both end sides, on which insertion openings 27 , 29 are present across the transverse to the direction of movement R. running edges of the hanging segments 9 , 11 , which are usually equipped with thickenings such as beads or piping, into the side of the receptacles 13th , 15th and along the guide grooves 17th , 19th are insertable. About the narrower cross-section and in the assembly position in the direction of movement R. oriented longitudinal openings 21 , 23 can adjoining sections of the hanging segments at the edges 9 , 11 or with the curtain segments 9 , 11 coupled connecting means, such as welt flaps, which are dimensioned narrower in cross-section than the thickenings, from the recordings 13th , 15th be led out. This results in a form-locking engagement between the hanging segments that is easy to assemble and dismantle 9 , 11 and the connecting device 7th created.

The connecting device 7th the 3 and 4th resembles the connection device in its mode of operation and in its basic structure 7th the 1 and 2 . In contrast to the execution of the 1 and 2 has the connecting device 7th the 3 and 4th a higher stability especially in the load direction. The stabilization device 7th is in the area of the connecting bridge 25th reinforced and has a central reinforcement area 45 on in which the two recordings 13th , 15th flow out. Another difference is that the outer contour of the recordings 13th , 15th not circular according to the execution according to the 1 and 2 is shaped, but by two rectilinear outer contour sections arranged at an angle to one another 47 , 49 is formed, one of which is attached to the reinforcement area 45 subsequent outer contour section 47 essentially parallel to the closing plane of the gate 1 is oriented in the assembled state.

For example, the connecting device 7th regardless of whether they are executed in the 1 , 2 or according to the execution in the 3 , 4th is shaped, a depth measured in the load direction in the range of 10 mm to 20 mm and one in the web direction R. measured height in the range of 15 mm to 30 mm.

A section of a gate according to the invention 1 is in its fully closed position 5 pictured, the one at the bottom 31 of the lower curtain segment 9 arranged stabilization device 33 which, for example, according to the WO 2004/088080 A1 is formed, having. The stabilization device 33 stands flat on the floor 35 on. On the side edges 37 of the door leaf 5 Guide devices, such as guide rollers or guide rails, can be arranged with associated guide elements on the wall delimiting the wall opening 39 which, for example, also have a frame profile 41 may have, are arranged, cooperate to the closing and opening movement of the door leaf 5 to lead and support. The guide device-guide element arrangement 43 defines the trajectory R. .

By means of the roller door according to the invention 1 the conflict of interest on which the present invention is based can be resolved from a high running speed and high wind stability on the one hand and a simple repair and maintenance option on the other hand. The separation of functions plays a role in stabilizing the curtain 3 that is about the stabilizer 33 is created, and the attachment of the hanging segments 9 , 11 what from the connector 7th is taken over, a crucial role. In the event of damage to the curtain 3 it is no longer necessary to use the complete curtain 3 to exchange.

The coordination can be such that the connecting device 7th form-fitting and / or jamming in the recess 61 is held. Referring again to 6th it can be seen that the security device 51 is dimensioned larger in the direction of the movement path than the safety device 7th and in the direction of the movement path over the safety device 7th protrudes and overlaps them. This allows the safety device 51 on the side edges 37 , 38 of the curtain segments 9 , 11 be created.

In the 10 , 11 is another exemplary embodiment of a connecting device 7th pictured, which basically like the Fastening device 7th from the 3 until 4th is designed and with two lateral mounting holes 63 , 65 for receiving fasteners such as screws, clips or the like, for fastening securing devices to one another 51 and connecting device 7th Mistake. The connecting device 7th can with the security device 51 according to the 7th until 9 or with the security scheme 51 according to 12th or 13th are combined, which represent further exemplary designs. Becomes the connecting device 7th with the security device 51 the end 12th combined, is the protection scheme 51 free of direct attachment to the curtain segments 9 , 11 . The fastening is done indirectly via the connection device 7th arranged mounting holes 63 , 65 who have two through holes 67 , 69 in the protection scheme 51 assigned. When combined with the safety device 51 the end 13th can be attached via the through holes 67 , 69 as well as via the central holes 55 , 57 take place.

The features disclosed in the above description, the drawings and the claims can be important both individually and in any combination for realizing the invention in the various configurations.
