Definitions
- the invention relates to a door, in particular a roller door, with a gap between an open position, in which it at least partially exposes a wall opening and possibly forms a multi-layer coil above the wall opening, and a closed position, in which it at least partially closes the wall opening
- a door leaf that can be moved along a movement path and is designed at least in sections as a web-shaped curtain made of flexible material, with the web-shaped curtain being assigned a stabilization device that extends transversely, in particular approximately perpendicularly, to the movement path, which, at least in the closed position, prevents a deformation of the curtain into a direction perpendicular to a through the movement path and the stabilization device spanned closing plane counteracts the load direction running.
- Roller doors of this type are used in particular to close hall entrances.
- the closing element which is designed as a door leaf, can be wound up on a wicket arranged above the entrance to the hall during a transition from the closed position to the open position. This ensures that the door leaf is stored in a space-saving manner in the open position.
- the door leaf can be formed in the form of a so-called slat armor with a large number of slats which are connected to one another in an articulated manner with respect to articulation axes running perpendicularly to the direction of movement of the closing element.
- the closing element can also be at least partially in the form of a sheet-like curtain, for example made of PVC. which can be formed from several blind segments which are subdivided in the direction of the web and connected to one another.
- the high-speed roller doors with a closing element or door leaf in the form of a web-shaped curtain must meet various, sometimes conflicting, requirements.
- the roller shutters must have a certain stability transversely to the direction of movement or transversely to the flächi gene extent 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.
- the individual curtains forming curtain segments are detachably connected to each other, because in the event of damage, repair and/or maintenance, a simple disassembly of the curtain and replacement of individual curtain segments are possible.
- roller doors are described, for example, in the international publication WO 2018/219512A1.
- the individual hanging segments are detachably fastened to one another via a connecting device consisting of stabilizing profiles designed as extruded aluminum profiles and piping that engages with the extruded aluminum profiles. While the required stability, particularly with regard to wind loads, and easy dismantling are achieved, the extruded aluminum profiles require a reduction in the running speed of the roller shutter and an increased noise level when the curtain is wound up and down. Because it has been found that the extruded aluminum profiles hit against the winding shaft when being wound up and unwound from the winding shaft and produce an uneven door movement. Doors with curtain segments connected to one another via connecting devices formed from metal profiles are also disclosed in DE 102019 126898 Ai and CN2480527Y.
- roller doors in which the curtain segments are permanently attached to one another, in particular by welding, or the curtain is made in one piece.
- the required stability against external influences can be achieved by providing the curtain with stabilizers, such as flat spring steel leaves.
- Roller shutters formed in this way are characterized by excellent running properties and speeds, without annoying winding noises occurring.
- the disadvantage of such roller shutters is, among other things, that in the event of damage, repair and/or maintenance, even minor damage to the one-piece curtain or damage to just individual curtain segments, the entire curtain generally has to be replaced, which results in a lot of work - and leads to costs. It is not possible to dismantle or replace individual curtain segments.
- WO 2004/088080 Ai proposes making the stabilizing element arranged in the closed position at the lower edge of the closing element elastically deformable so that it can convert at least part of the impact energy into deformation energy.
- At least one guide device interacting with the guide element is arranged on at least one lateral edge of the closing element, which is set up to detach from the guide element when a vehicle impacts the closing element in order to prevent damage to the To avoid hanging, the guide element or the guide device.
- an inlet arrangement can be arranged at the upper edge of the guide element, with which the guide member can be automatically inserted into the guide element during a closing movement of the closing element.
- the inlet arrangement can be combined with a prestressing device, with which the closing element or the stabilization element is urged in opposite directions and transverse to the direction of movement of the closing element.
- neither the flexibility of the stabilizing element nor the detachable 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.
- the object of the invention is to improve a generic goal, in particular to provide a goal that has a high running speed and wind stability while ensuring easy repair and maintenance.
- the door leaf can be wound up above the wall opening to form a multi-layer coil, so that the movement path section adjoining the vertical path section is designed in a spiral shape.
- the path of movement of the door leaf can be predetermined, for example, via guide devices arranged on the lateral edges of the door leaf, which interact with guide elements arranged on the wall delimiting the wall opening, such as guide rails, in order to guide the door leaf during the opening and closing movement.
- the curtain can also have a rigid lower part, for example made of metal, such as steel or aluminum, which forms in particular the lower edge section of the curtain in its closed position, for example if increased wind stability is required.
- the web-shaped curtain is assigned a stabilization device that extends transversely, in particular approximately perpendicularly, to the movement path and, at least in the closed position, counteracts a deformation of the curtain in a load direction running perpendicular to a closing plane spanned by the movement path and the stabilization device.
- the stabilization device can usually be rigid and/or made of aluminum or metal.
- the web-shaped blind has at least two blind segments that follow one another in the direction of the path of movement, which are detachably connected to one another along at least one predetermined separating line that extends in the closing plane, preferably approximately perpendicular to the path of motion, in such a way that the edges of the blind segments that face one another remain deformable.
- the predetermined dividing line can be an imaginary axis in the area of the attachment zone between the two curtain segments.
- the predetermined severing line can be arranged in relation to the movement path, in particular centrally, between the edges of the path segments to be connected that face one another.
- the term “designated separating line” used in this application includes a designated separating area that can have an extent of the order of magnitude of a multiple of the thickness of the curtain segments both in the direction of the movement path and in a direction perpendicular to the closing plane.
- a curtain segment forming the lower edge of the curtain is connected to a curtain segment that trails behind in the closing movement.
- 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 be designed in accordance with WO 2004/088080 Ai, the content of which is incorporated herein by reference in its entirety.
- the connecting device has the advantage that the connecting device can deform back to its original shape after deformation, for example as a result of a collision with a forklift truck, so that the curtain can continue to close the wall opening cleanly and reliably is movable along the path of movement, in particular in the open position can also be wound up to form a roll.
- the connecting device consists exclusively of an elastically deformable material, in particular an elastomeric material and/or plastic.
- the materials PVC, in particular rigid PVC, PE, EPDM, SBR and silicone are suitable.
- the predetermined separating line or the predetermined separating area is formed in the sense of this description and the claims by the transitions between the connecting device and the edges of the curtain segments.
- the connec tion device is designed in such a way that a curtain segment forming the lower edge of the curtain and a further curtain segment can each be detachably fastened or fastened to it. Because the connecting device can be releasably connected to both curtain segments to be connected, it is not only possible to easily replace the curtain segments in the event of damage and/or maintenance, but also to replace the connecting device itself with little installation effort if it needs to be replaced .
- the detachable fastening can be realized by a form fit, which is characterized in particular by the fact that simple assembly and disassembly of the blind segments or the connecting device is ensured.
- the recordings are made in one piece.
- the receptacles in particular the connection device, can be produced in a plastic injection molding process, a plastic extrusion process or in a foaming process. It is thus possible to resort to cost-effective production processes that are suitable for mass production.
- the receptacles can each have a guide groove extending in the longitudinal direction of the receptacles, which is oriented transversely to the movement path of the door leaf when mounted on the curtain, in particular with a constant cross-section in the direction of the predetermined dividing line, for inserting the edges of the curtain segments. The edges are inserted in the longitudinal direction of the guide grooves.
- the receptacles can each have a longitudinal opening oriented in the direction of the movement path of the door leaf for sections of the curtain segments adjoining the edges or for connecting means coupled to the curtain segments.
- the edges are either made or formed in one piece with the respective curtain segments or are part of separate connecting means which are in particular cohesively coupled to the curtain segments.
- the Longitudinal openings in the load direction have a clear width that is less than the maximum dimensions of the thickenings accommodated in the receptacles in this direction.
- the form-fitting coordination of the guide groove and edge means that a predefined assembly and disassembly direction is specified, so that simple assembly and disassembly is guaranteed and incorrect assembly can be avoided.
- the edges are guided into the guide grooves in the receptacle. Because of the form-fitting interlocking, the connecting device can be pulled or pushed onto the blind segments in a simple manner without tilting or jamming.
- the connecting device Since the connecting device releases at least one of the hanging segments as soon as the applied load exceeds a predetermined load limit, the connecting device is equipped with protection against damage.
- the attachment interface between the curtain segment and the connecting device forms a predetermined separating line or a predetermined separating area, so that the attachment, in particular the form-fitting engagement, between the curtain segment and the connecting device is released if the load is too high.
- protection against damage is at the expense of at least partial, in particular automatic, disassembly of the door leaf.
- the edges of the curtain segments can be adjusted to a dimension of the longitudinal opening
- the openings of the receptacles of the connecting devices must be shape-matched so that when the predetermined load limit is exceeded, 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.
- the load limit is about 20 kg/m.
- the detachable connection between the blind segments, in particular the connecting device is preferably designed in such a way that damage to the blind segment trailing behind in the closing movement direction is avoided in the event of a load. Under certain circumstances, this can be done at the cost of damaging the curtain segment that is leading in the direction of the closing movement and, in particular, forms the lower edge of the curtain.
- the connecting device is arranged at a distance in the range of 250 mm to 1,250 mm from the ground in the closed position. Due to the fact that the curtain is usually damaged in a lower edge area in the closed position, it is advantageous to arrange the connecting device at a vertical height such that such collision damage is largely possible by simply replacing the lower curtain segment, including the connecting device if necessary.
- the connecting device is at a distance in the range of 350 mm to 1000 mm or up to 500 mm from the ground.
- the safety 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.
- the securing device has a receiving recess which is shaped in relation to the connecting device and in which a lateral end of the connecting device can be received, in particular in a clamped manner.
- the safety device can be designed to increase stability in the lateral edge area of the connection device.
- the securing device in the lateral edge area of the connecting device can counteract a deformation of the securing device in the direction of the load.
- the safety device can take on a double function, namely avoiding a relative movement of the blind segments in the direction of the predetermined severing line and reducing or avoiding a deformation of a lateral edge region of the safety device in the direction of the load.
- the connecting 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 safety device and connecting device to one another.
- fastening means such as screws, clips or the like
- the safety device is not directly attached to the curtain segments, but is only indirectly coupled to the curtain segments via the connecting device. This can be advantageous, for example, because in the event of severe overloading, a complete separation of the curtain segments from one another can be guaranteed, in order to avoid possible damage to the curtain segments.
- 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 stabilizing device in a direction perpendicular to the load direction.
- the load direction points in the space to be closed by the door leaf or in the opposite direction. This can further reduce damage resulting from a collision with a forklift, for example, 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 curtain Connection device comes.
- the inlet arrangement on the upper edge of the guide device has at least two pretensioning devices that can be placed on opposing boundary surfaces of the door leaf and/or a stabilization element arranged on the lower edge of it, with which the door leaf or the stabilization device is placed in opposite directions and perpendicular to the movement path direction of the door leaf.
- the hanging segment which leads during a shooting movement along the movement path and in particular forms the lower edge of the hanging has an optical indicator which differs optically from the neighboring hanging segment.
- the optical indicator can be a coloring or color of the curtain segment, an imprint or an indication means applied in some other way to the curtain segment, for example glued on.
- the optical indicator can have an increased degree of reflection compared to the adjacent curtain segment.
- the visual indicator can be designed as a yellow or red warning balk, for example, in order to create an additional visual indication of a possible hazardous area.
- At least one connecting device can be provided with a safety device designed to absorb axial forces acting parallel to the edges of the curtain segments extending perpendicularly to the path of movement.
- a safety device designed to absorb axial forces acting parallel to the edges of the curtain segments extending perpendicularly to the path of movement.
- Such a safety device can prevent the edges of the door leaf extending parallel to the movement path from being offset in a direction perpendicular to the movement path, because the corresponding axial forces are absorbed by the safety device.
- a safety device designed to absorb axial forces can have safety means fixed with respect to the wall opening and at least one safety module attached to the door leaf, in particular the connecting device, with at least one contact surface that can be placed on a counter surface of the safety means to absorb axial forces.
- the contact surface of the safety module is placed against the mating surface of the safety means. In this way, an offset of the lateral edge of the door leaf, which extends parallel to the path of movement, is prevented in a direction perpendicular to the path of movement.
- the contact surface of the security module can be formed by at least one guide roller that is rotatably mounted, in particular with respect to a roller axis running perpendicular to the locking plane in the closed position, which preferably in the closed position extends approximately in the direction of gravity and from one of a lateral Edge of the door leaf penetrated through slot interspersed, be included as a hollow profile security means.
- the safety device acts not only to absorb axial forces, but also as a guide to guide the movement of the door leaf.
- the desired axial force safeguard can be achieved without impairing the deformability of the connecting device if the securing device has a pull-out safeguard that connects the safety modules attached to opposite axial ends of the connecting device with one another, for example in the form of a stranded body ,
- a cable such as a wire cable
- the tension safety device can extend through a channel in the connecting device that extends parallel to the edges of the blind segments.
