Description

The invention relates to a roller door with a door leaf that can be moved between an open position in which it at least partially exposes a wall opening and forms a multilayered roll above the wall opening, and a closed position in which it at least partially closes the wall opening, and in the area of the in the closed position Articulated arrangements for guiding the movement of the door, each of which has a plurality of articulated joint axes that are articulated with respect to the lateral edges and approximately parallel to the plane of the door.

Such roller doors are for example in the DE 10 2009 017 767 A1 described. Among other things, they are used as so-called high-speed doors to close industrial halls. On the one hand, it is important that the door leaf movement is safely guided. On the other hand, it is important that there is often only little space available for accommodating the door leaf in the open position. In view of these requirements, a roller shutter is already proposed in the cited document in which at least one articulation arrangement is at least has a hinge plate which is placed on an end face of a rigid door leaf element, for example designed as a sandwich element, and which extends approximately perpendicular to the hinge axis. As a result, an increase in the thickness of the overall structure due to the hinge arrangement can be avoided and the space required for roller doors in the open position can be reduced. However, it has been shown that such gates still require a considerable amount of space and the speed of movement of the gate leaf is limited.

In view of these problems in the prior art, the invention is based on the object of providing a roller door that can be stored in the open position with little space requirement and enables a high opening or closing speed while at the same time ensuring reliable guidance of the door leaf movement.

According to the invention, this object is achieved by a further development of the known goals, which is essentially characterized in that the door leaf is made of a flexible material, such as a plastic film or a plastic film, which can be wound at least in sections with respect to a winding axis running perpendicular to the lateral door leaf edges and parallel to the plane of the door leaf. -bahn is formed, which is stabilized by two, three or more perpendicular to the lateral edges and approximately in the door leaf plane extending stabilizing devices, the door leaf is connected to the hinge arrangements only via the stabilizing devices.

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 stabilizing devices of the door leaf create a robust door leaf. The door leaf is guided with the aid of the joint members of the joint arrangements coupled to the stabilizing devices, whereby the tensile and thrust forces occurring during the movement of the door leaf can be transmitted via the joint arrangements. The door leaf can be made correspondingly light. It only has to be ensured that the stabilizing devices of the door leaf are securely coupled to the joint members of the joint arrangements.

Commercially available, preferably transparent PVC and / or polycarbonate can be used as a flexible material for manufacturing doors according to the invention. The thickness of the plastic sheet is selected according to the requirements. In any case, by using the flexible material in the form of a plastic film or sheet, an adaptation of the door leaf shape to the spiral shape in the open position can be ensured while ensuring a small winding radius.

Polycarbonate in particular has proven to be a material with excellent properties for use in doors according to the invention. The material has a 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.

The roller doors according to the invention combine the advantages of a roller door construction with rigid slats and lateral hinge arrangements with the advantages of foil doors in order to provide a high-speed door that has a high opening and closing speed thanks to the flexible construction of the door leaf while at the same time providing reliable guidance through the Joint arrangements and relief of the door leaf through the transmission of thrust or tensile forces via the joint arrangements made possible. The connection of the door leaf to the hinge arrangements can be implemented in a particularly stable manner, because the stabilization devices provided in any case to avoid bulges under wind loads can be used for this purpose. The stabilizing devices, together with the joint arrangements, form, as it were, a rigid frame for the flexible door leaf.

In a preferred embodiment of the invention, the door leaf has a segment (hereinafter also referred to as "pane") of preferably transparent and pliable or flexible material with segment or pane edges running approximately perpendicular to the side edges of the door leaf, the segment - or disc edges are provided with a thickening and at least one stabilization device has a stabilization profile with at least one receiving area for receiving the thickening on a segment or disc edge. The stabilization profile preferably extends over the entire width of the door leaf in a direction perpendicular to the lateral door leaf edges, the receiving area also expediently extending over the entire width of the door leaf. Additionally or alternatively, at least one segment edge can be designed without a thickening and can be held on the stabilizing device in a material and / or force-fit manner, for example via a terminal strip.

In all embodiments of the invention, the segment or the pane can extend over two, three or more articulated links in the direction of movement of the door leaf or in a direction running parallel to the lateral edges of the door leaf. Then the articulated links arranged between the stabilizing devices are only indirectly connected to the door leaf via the articulated links directly connected to the stabilizing device.

The stabilization profile can be designed, for example, as an extruded plastic profile. In a particularly preferred embodiment of the invention, however, the stabilizing profile is designed as an extruded aluminum profile. Such an extruded aluminum profile combines high strength with low weight.

The thickening at the segment or pane edges can be realized by glued or welded-on piping strips, which are positively received in corresponding receiving areas of the stabilizing profiles. In addition, however, other connection options are also thought of, for example via a terminal strip, in order to be able to easily exchange the bendable or flexible segments when installed.

In the case of roller doors according to the invention, the door leaf is only connected to the hinge arrangement, which can be implemented as a hinge band, for example, via the stabilizing profiles which also serve as wind reinforcement. The lateral edges of the individual panes or door leaf segments can extend over two, three or more articulated links, with individual articulated links being only indirectly connected to the door leaf segments or panes via the articulated links directly connected to the stabilizing profiles.

In the context of the invention, it has proven to be particularly expedient if at least one segment edge is attached to the stabilization device with a clamping member which can be detachably fixed to the stabilization device and is preferably at least partially received in the stabilization device and / or delimits the stabilization device. In this embodiment of the invention, the individual panes or door leaf segments can be exchanged particularly easily by releasing the clamping member from the stabilizing device and then removing the corresponding segment edge from the stabilizing device. If both segment edges of a segment are attached to the stabilization device with corresponding clamping members, the corresponding segment can be completely removed from the door leaf without impairing the stability of the basic structure, consisting of the hinge arrangements and the stabilization devices.

In a particularly preferred embodiment of the invention, the segment edge is arranged between the clamping member of a sealing strip, which can be releasably secured to the stabilizing device, in order to ensure a tight transition between the stabilizing device and the door leaf segment.

The intermediate hinge points of the hinge arrangement or the hinge are not connected to the flexible material. The hinge or the joint arrangement takes over the pushing and pulling forces in the course of the opening and closing movement. The connection of the stabilization profiles or wind stiffeners to the hinge band can be made in the grid of the hinge points. This means that different pane heights can be achieved. In the case of narrow goals, the number of stabilizing profiles or wind stiffeners can be selected to be lower, ie the section height can be particularly large while wide goals can be equipped with several stabilization profiles or wind stiffeners for smaller section heights for stabilization.

Structurally, it has proven to be useful if the door leaf has at least two panes of flexible material arranged one behind the other in the direction of movement of the door leaf, between which a stabilizing profile with two receiving areas for receiving on facing pane edges is arranged. With the stabilization profile, the connection between successive disks made of flexible material is brought about.

As already explained above, with a view to obtaining a stable door leaf construction it has proven to be expedient if at least one stabilizing device extends approximately parallel to a hinge axis over the entire door leaf width. A trouble-free connection of the stabilization device without impairing the mobility of the joint arrangement is achieved if the stabilization device is connected along the joint axis to at least one, preferably to two joint arrangements provided on opposite side door leaf edges.

In particular in the case of particularly high and / or wide door leaves, it has proven to be useful with a view to the desired stabilization if at least one reinforcement strip is provided which extends approximately parallel to the lateral edge of the door leaf and is attached to the door leaf. Using appropriate reinforcement strips, which can also be glued and / or welded onto the panes of the door leaf, for example, sufficient overall stability can be achieved even if the material of the pane itself does not provide sufficient flexural rigidity.

Similar to the ones in the DE 10 2009 017 767 A1 The roller shutter described can be assigned to a roller shutter according to the invention with a flexible door leaf at least one spiral guide track for guiding the door leaf movement and for determining the opening position of the door leaf, with at least one joint member on its side facing away from the door leaf having a guide arrangement that interacts with the guide track to guide the door leaf movement, which preferably has at least one guide roller which is rotatably mounted with respect to a roller axis running parallel to the joint axes and which is preferably received in a guide track at least in the open position of the door leaf.

When operating the known roller doors with a door leaf formed at least partially from a flexible material such as a plastic film and an optionally oval-spiral guide track for guiding the door leaf movement, it has been shown that at high door leaf speeds there is increased wear on the guide track and of the door leaf can come. According to a further aspect of the invention, which can be used with particular advantage together with the previously explained aspects of the invention, this problem is solved by a door, in particular a roller door, with a position between an open position in which it at least partially exposes a wall opening and above the wall opening forms a multilayered roll, and a closed position in which it at least partially closes the wall opening, movable door leaf, which is at least partially made of a flexible material, such as a plastic film, which is essentially characterized in that the at one Opening movement leading edge of the door leaf is formed by a leading stabilizing device connected in a rotationally fixed manner to an upper edge of a segment made of a flexible material in the closed position, which stabilizing device is rotationally fixed to a preferably predetermined by guide rails, at least in sections curved guideway cooperating guide arrangement is connected, the alignment of the guide arrangement follows the course of the guide track.

This solution is based on the knowledge that the increased wear observed at high door travel speeds during the operation of conventional doors is essentially caused by the fact that the upper edge of the door leaf made of a flexible material is deflected out of the door leaf plane when it enters the spiral guide track in such a way that first of all, the door leaf bulges inwards, which in the further course of the opening process suddenly changes into an bulge outwards, which is retained in the open position. The sudden change from the inside curve to an outside curve in the course of the opening movement leads, on the one hand, to a high load on the door leaf itself and, on the other hand, to an increased radial load on the guideway. This causes the observed increased wear.

The non-rotatable connection of the upper edge of a door leaf segment made of flexible material to the stabilization device forming the leading edge of the door leaf during the opening movement and the non-rotatable connection of the stabilization device to the guide arrangement that cooperates with the guide track and follows its course, on the other hand, leads to the upper edge of the Door leaf segment made of flexible material is forcibly deflected outward when the guide arrangement enters the spiral guide track, as a result of which an external curvature is forcibly impressed on the door leaf segment. The transfer of this outer curvature of the upper segment in the course of the opening movement is transferred to the following segments of the door leaf when the following stabilization devices between the individual door leaf segments are rotatably connected to the guide rollers to be guided through the guideway, whereby the roller axes, as already mentioned above, are parallel to the joint axes of the articulated interconnected Joint members, in particular coaxial thereto, can run. Overall, a defined curvature of the door leaf can be ensured in the course of the opening movement. This avoids excessive loads on the door leaf and the guideway and prevents increased wear.

The guide arrangement non-rotatably connected to the leading stabilizing device can have two, three or more guide pins or rollers arranged one behind the other in the direction of movement of the door leaf, which are attached to a common carrier non-rotatably connected to the leading stabilizing device. By using two, three or more guide pins or rollers attached one behind the other in the direction of movement of the door leaf and interacting with the guide rail, it is achieved that the alignment of the guide arrangement as a whole approximately follows the curved course of the guide track. In this case, the carrier is preferably attached to a joint member moving forward during the opening movement, it also being possible for the carrier to be attached to the joint member in a rotationally fixed manner. If the guide arrangement has two, three or more guide rollers arranged one behind the other in the direction of movement of the door leaf, each can be connected rotatably with respect to a roller axis running parallel to the joint axes on the common carrier connected non-rotatably to the leading stabilizing device.

In addition to the usual spiral guideway, alternative guideways such as an oval spiral, a horizontal deflection or a vertical guide can be implemented depending on the space required on the building.

In all embodiments of the invention, it has proven to be advantageous if at least one joint member is assigned a sealing arrangement that can be placed against a boundary surface of the door leaf in the closed position. In this context, it has proven to be particularly favorable if the individual sealing arrangements assigned to the joint members form a continuous sealing strip in the closed position in the manner of a chain seal, to which individual segments or disks of the door leaf or the lateral edges of the door leaf as a whole are attached can create closed state.

In the context of the invention, embodiments are also contemplated in which the sealing arrangement rests against the outer boundary surface of the door leaf facing away from the space to be closed with the door leaf. However, it has been shown that a particularly reliable seal can be achieved when the sealing arrangement rests against the inner boundary surface of the door leaf facing away from the outer boundary surface and facing the space to be closed with the door leaf. This aspect of the invention is in turn based on a precise investigation of the kinematics of the door leaf movement back when entering the spiral guideway. In this phase of the movement, the door leaf is pushed outwards and can thus strike against a sealing arrangement lying on the outside, which in turn can lead to increased wear of the door leaf itself and the sealing arrangement. However, if the sealing arrangement comes into contact with an inner delimiting surface of the door leaf, this cause of wear is eliminated and an overall improved seal is thus achieved.

As already mentioned above, it has proven to be expedient if the sealing arrangements assigned to the joint members in the closed position form a continuous sealing strip in the manner of a chain seal. In this context, such embodiments are also intended in which the sealing arrangements have at least one sealing element extending over two, three or more joint members, so that a gapless seal takes place over the corresponding number of joint members. The connection of this sealing element to the joint links can take place via separate fastening elements attached to the joint links. As an alternative or in addition, the seal receptacle can also be integrated into the individual joint links. A composite material made of plastic and metal can be used to produce the joint links with possibly integrated sealing elements.

Door leaves of doors according to the invention can be moved into the open position at a particularly high door leaf speed. However, care must be taken that when the opening position is reached and the door leaf is braked accordingly, there is no warping of the door leaf in the area of the door leaf edge trailing during the opening movement. In the context of the invention, it has proven to be particularly expedient in this context if a pretensioning device, which can be coupled to an edge of the door leaf trailing during the opening movement, is used to brake the opening movement and to provide a pretensioning force that urges the door leaf from the open position into the closed position is provided. Coupling the pretensioning device to the trailing edge of the door leaf ensures that the lower area of the door leaf in the closed position with the edge trailing during the opening movement is pretensioned in the desired manner with the aid of the pretensioning device when the opening position is reached. In this way, warping of the door leaf in the area of the edge trailing during the opening movement can be avoided. At the same time, the pretensioning device can provide a breakaway torque that is advantageous for initiating a closing movement, because the door leaf is pretensioned into the closed position with the pretensioning device coupled indirectly to its edge trailing during the opening movement.

In the context of the invention, it has proven to be particularly advantageous if the pretensioning device has a tension spring which extends approximately in the direction of gravity and is designed, for example, as an expander cable, i.e. at least partially made of an elastomeric material, the upper end of which is moved by an in the course of the opening movement Area of the edge of the door leaf attached during the opening movement is detected and carried along. Additionally or alternatively, the use of tension springs is also envisaged.

In all embodiments of the invention, it has proven to be beneficial for kinematic reasons if the length of at least one joint member in a direction running parallel to the lateral edges in the closed position is more than 20 mm, preferably more than 30 mm and / or less than 400 mm amounts to.

This in Fig. 1 The roller door shown comprises a door leaf, designated as a whole by 10, which is formed from panes 12 made of flexible, transparent material which are connected to one another via stabilizing profiles 40. Joint arrangements in the form of hinge strips 20 and 30, which are connected to the door leaf 10 via the stabilizing profiles 40, are arranged on the lateral edges of the door leaf 10. The hinge straps have guide rollers 22 and 32 at the joints between the individual hinge members on their side facing away from the door leaf 10, with which the door leaf movement can be guided using suitable guide rails.

According to Fig. 1 the hinge straps 20 and 30 forming a push-pull association are formed from hinge members 26 and 36, respectively, which have a fork-shaped receptacle or a comparable design at one end into which a pin of an adjacent hinge member engages. Fork and pin are penetrated by a common hinge pin in order to produce an articulated connection between successive hinge members. The roller axes of the guide rollers 22 and 32 run parallel to the joint axes, preferably co-linear therewith. Likewise, the stabilizing profiles 40 designed as extruded aluminum profiles run parallel to the joint axes or roller axes. The connection of the stabilizing profiles 40 to the joint arrangements 20 and 30 can take place in the pivot points of the hinge straps.

According to Fig. 2 a roller shutter according to the invention has a spiral-shaped guide track 100 into which the guide rollers 22 and 32 attached to the hinge strips 20 and 30 move when the open position is reached. In Fig. 2 the hinge members 26 and 36 are hidden in the area of the spiral guide track in order to be able to achieve a better representation of the door leaf itself. It can be seen that disks 12 made of flexible material readily adapt to the desired spiral shape. For this it is also not necessary for the disks 12 themselves to be connected to the hinge straps. Rather, it is sufficient if only the stabilizing profiles 40 between the individual panes are connected to the joint arrangements in the form of the hinge strips 20 and 30, respectively. It can also be seen that the individual panes made of flexible material extend over a considerable height of the door leaf can extend. This is a particular advantage compared to conventional louvre doors, which enable the spiral diameter to be minimized.

According to Fig. 3 the panes 12 have thickenings formed by welded-on piping 14 on the pane edges running perpendicular to the lateral edges, which are received in the receiving areas 42 and 44 of the stabilizing profiles. The width of the receiving areas 42 and 44 tapers starting from the receiving areas 42 and 44 in the radial direction such that the receiving areas in their mouth areas only allow the windows 12 with glued-on piping flags to pass through, but not the thickening or piping 14. A secure connection of individual panes via the stabilizing profiles 40 is thereby achieved. However, no tensile or shear forces have to be transmitted via this connection. These are transmitted via the hinge strips 20 and 30, respectively.

According to Fig. 4 the hinge straps 20 and 30 are connected via the stabilizing elements 40 with the aid of a screw which runs colinearly to the roller axis of the guide rollers 22 and 32 and is secured with a lock nut 50. The screw engages in a corresponding recess 52 (cf. Fig. 3 ) into the stabilization profiles 40. In Fig. 4 it can be seen that the hinge axis of the articulated connection between successive hinge members 26, roller axis, screw axis and the axis of the stabilizing profile 40 are approximately colinear.

In the Fig. 5 The illustrated embodiment of the invention differs essentially in this way from that on the basis of FIG Fig. 3 illustrated embodiment that the stabilization profile 140 has two receiving areas 142 and 144 which are used to receive a clamping member 150 (cf. Figure 5b ) and a sealing strip 160 (cf. Figure 5c ) are designed. In the assembled state, the clamping member and the sealing strip are received in the receiving areas 142 and 144, with a segment or disk edge being arranged between the clamping member 150 and the sealing strip 160 (cf. Fig. 5d ).

In the Fig. 6 The illustrated embodiment of the invention differs essentially in this way from that on the basis of FIG Fig. 5 illustrated embodiment that the clamping member 250 represents a limitation of the stabilization device 240. For this purpose, the clamping member 250, as in Fig. 6 shown, clipped into the stabilization profile 240. In this embodiment of the invention, too, the edge of the disk 212 is arranged in the assembled state between the clamping member 250 and the sealing strip 260, the sealing strip 260 being received with a fastening bead in a corresponding receptacle of the stabilizing profile.

Figure 7a ) shows joint members 126 designed as aluminum extruded elements, the connection of the rollers 122 to the joint arrangement via slide bearings being shown.

Figure 7b ) shows articulated links designed as a plastic injection-molded hybrid with a plastic injection-molded jacket and a sheet steel core.

At the in Fig. 8 In the illustrated embodiment of the invention, a sealing arrangement 370 is placed on joint members 360. The sealing arrangement 370 has a sealing strip 380 which, in the closed state, forms a continuous seal because the sealing strip 380 extends over a plurality of joint members 360. An outer boundary surface of the individual segments or panes of the door leaf can be placed against the sealing strip in the closed state.

In Fig. 9 the connection of the stabilization profiles 240 to the joint arrangement is illustrated by screw bolts running colinearly to the joint axes, with the stabilization profile on the one hand and the guide rollers on the joint arrangement being arranged on the other hand.

At the in Fig. 10 The embodiment of the invention shown here, the leading edge of the door leaf during an opening movement is formed by a stabilizing device 40, which is non-rotatably connected to a guide arrangement designated overall by 60. The guide arrangement comprises an approximately U-shaped holder 62. An outer leg of the U-shaped holder 62 is fastened to the stabilizing device 40 via a bolt 64 and a locking screw 66. Bolt 64 and screw 66 are spaced apart from one another in the direction of movement of the door leaf indicated by the arrow P. In this way, a non-rotatable connection of the holder 62 to the stabilizing device 40 is achieved. Two guide rollers 22 arranged one behind the other in the direction of movement of the door leaf P are attached to the holder 62, each of which is attached to the holder 62 so as to be rotatable with respect to the roller axes running parallel to the joint axes of the joint or hinge members 26. The holder 62 is moreover non-rotatably connected to the hinge or joint member 26 advancing during the opening movement.

In Figure 10b the door leaf equipped with the guide arrangement 60 is shown as it enters the spiral guide track. Due to the forced guidance of the guide rollers 22 rotatably arranged on the holder 62, the stabilization device 40, which is connected to the guide arrangement 60 in a rotationally fixed manner, and the edge of the disc 12 which is connected to it in a rotationally fixed manner during the opening movement is carried along or aligned in accordance with the guide track and the disc 12 is thus forced to the outside arched. This curvature is transferred to the subsequent panes of the door leaf because the one between the individual panes 12 provided stabilization devices 40 are rotatably connected to the guide rollers 22 with respect to a roller axis running colinearly to the joint axes of the joint members. This forced guidance of the guide arrangement 60, the guide rollers 22 attached to it, the stabilizing device 40 non-rotatably connected to it, and the upper edge of the segment advancing during the opening movement or the pane 12 advancing during the opening movement, an uncontrolled turning of the pane occurs 12 and the subsequent panes 12 between an inner curvature and an outer curvature are avoided and thus the wear resistance of a door according to the invention is increased.

Incidentally, the in Fig. 10 illustrated embodiment of the invention by the basis of the Figures 1 to 4 Embodiments of the invention shown in that the individual joint members have two fork-shaped receptacles on one side and pegs engaging in the fork-shaped receptacles of an adjacent joint member on their other side. An improved torsional rigidity of the joint arrangement is achieved as a result.

At the in Fig. 11 The illustrated embodiment of the invention shows a sealing arrangement 470 in the closed position on an inner surface of the panes 12 facing the space to be closed with the door leaf. The sealing arrangement 470 comprises one, two, three or more joint members 26 overlapping U-shaped sealing profile, from which a sealing lip 472 extends in the direction of an inner boundary surface of the disk 12.

The sealing lip 472 is equipped on its edge facing the inner boundary surface of the disk 12 with a hollow chamber seal 474, by means of which a particularly reliable sealing effect can be achieved. The sealing profile 476 of the in Fig. 11 The sealing arrangement illustrated may extend over two, three or more hinge members extending between successive stabilizing devices 240. Overall, the sealing arrangement 470 extends approximately in the direction of gravity in the door leaf closed position.

In Fig. 12 is a perspective view from above of one of two side frame profiles 600 of a gate according to the invention. The lateral frame profile 600 has a channel 610 running in the direction of gravity, in which a tension spring 500 is received, from which in FIG Fig. 12 the top can be seen. At the upper end of the tension spring 500, an exposed arm 520 is attached to which a driver (not shown) attached to the lower joint member 26 trailing during the opening movement comes into contact during the opening movement. With the aid of the driver, the arm 520 and thus also the upper end of the tension spring 500 can be carried upwards in the course of the opening movement, and so on the tension spring 500 can be tensioned. As a result, on the one hand, the opening movement of the door leaf is braked and, on the other hand, in the open position of the door leaf, a breakaway torque is provided which promotes the initiation of a closing movement.

The invention is not limited to the embodiment explained with reference to the drawing. Rather, it is also intended to provide additional stabilization strips parallel to the side edges of the door leaf in order to achieve additional stabilization with regard to wind loads. The push-pull assemblies implemented in the form of hinge straps in the embodiment described can also be designed differently. The connection of the stabilizing elements with the push-pull assembly can also be designed to be articulated, avoiding a rigid connection. This creates a floating mounting that helps to avoid the transmission of torsional forces from the wound-up segments to the push-pull assembly.
