Description

ROLLING GATE

The invention relates to a roller door with a between an open position in which it at least partially releases a wall opening and above the wall opening forms a multi-layer winding, and a closed position in which it at least partially closes the wall opening, movable door leaf and in the region in the closed position arranged at least in sections in the direction of gravity extending lateral edges of the door leaf and fixed to the door leaf hinge assemblies for guiding the Torblattbewegung, each of which has a plurality of with respect to perpendicular to the lateral edges and approximately parallel to the door leaf hinge axes articulated joint members.

Such roller doors are described for example in DE 10 2009 017 767 A1. They are used, inter alia, as so-called high-speed doors for closing industrial halls. It depends on the one hand, that the Torblattbewegung is guided safely. On the other hand, it is important that often only little space is available to accommodate the door leaf in the open position. In view of these requirements, a roll-up door is already proposed in the cited document, in which at least one joint arrangement minimizes at least one on one approximately perpendicular to the hinge axis extending end face of a example designed as sandwich elements rigid door leaf element patch and attached thereto hinge plate has. As a result, an increase in the thickness of the overall construction can be avoided by the hinge assembly and the space required for roller doors in the open position can be reduced. However, it has been shown that corresponding gates still bring a considerable amount of space and the Torblattbewegungsgeschwindigkeit is limited.

In view of these problems in the prior art, the present invention seeks to provide a roller door that can be stored in the open position with little space and a high opening and closing speed while ensuring reliable guidance of the Torblattbewegung allows.

According to the invention, this object is achieved by a development of the known goals, which is characterized essentially in that the door leaf at least partially from a flexible, with respect to a perpendicular to the side door leaf edges and parallel to the door leaf extending winding axis aufwickelbaren material, such as a plastic film or -bahn is formed, which is stabilized by two, three or more perpendicular to the lateral edges and extending approximately in the Torblattebene stabilizers, wherein the door leaf is connected only via the stabilizers with the hinge assemblies.

The design of the door leaf at least in sections of flexible material allows a reduction in space requirements, because the material adapts itself to the winding to be formed even in the open position, thus allowing a small spiral diameter in the open position. At the same time a robust door leaf is realized by the stabilization devices of the door leaf. The guiding of the door leaf takes place with the aid of the joint elements of the joint arrangements coupled to the stabilizing devices, whereby the tensile or shear forces occurring during the door leaf movement can be transmitted via the joint arrangements. Accordingly easy, the door leaf can be executed. It only needs to be taken to ensure that the stabilizing devices of the door leaf are securely coupled to the hinge members of the joint assemblies.

Commercially available, preferably transparent, PVC and / or polycarbonate can be used as flexible material for producing gates according to the invention. The thickness of the plastic sheet is chosen according to the requirements. In any case, by using the flexible material in the form of a plastic film or web, an adaptation of the Torblattform be ensured to the spiral shape in the open position while ensuring a small winding radius. In particular, polycarbonate has proven to be a material with excellent properties for use in gates according to the invention. The material has a high elasticity with sufficient bending stiffness to follow even with large widths of the winding contour. In addition, the material has other positive properties such as a high impact resistance.

By rolling doors according to the invention, therefore, the merits of a roller shutter construction with rigid fins and side hinge assemblies combined with the advantages of film doors, so as to provide a high-speed door, the high opening and closing speed by the flexible construction of the door leaf while providing a reliable guide through the Joint arrangements and relief of the door leaf by the transmission of shear or tensile forces on the joint arrangements allows. In this case, the connection of the door leaf to the joint arrangements can be realized particularly stable, because this can be used to prevent bulges under wind loads provided stabilizers. The stabilizing devices together with the joint arrangements form, as it were, a rigid skeleton for the flexible door leaf.

In a preferred embodiment of the invention, the door leaf has a segment (hereinafter also referred to as "disk") made of preferably transparent and flexible material with approximately perpendicular to the side edges of the door leaf segment or disc edges, wherein the segment The stabilizing profile preferably extends over the entire width of the door leaf in a direction perpendicular to the side door leaf edges In addition, or alternatively, at least one edge of the segment can be made without thickening and material and / or non-positive, such as via a terminal strip , be held on the stabilizer.

In all embodiments of the invention, the segment or the disc in the Torblattbewegungsrichtung or parallel to the lateral edges of the door leaf extending direction over two, three or more hinge members may extend. Then arranged between the stabilizing means hinge members are only indirectly connected via the directly connected to the stabilizer hinge members with the door leaf.

The stabilization profile can be designed, for example, as a plastic extruded profile. In a particularly preferred embodiment of the invention, however, the stabilization profile is designed as an aluminum extruded profile. Such an aluminum extruded profile combines high strength with a low weight. The thickening at the segment or disc edges can be realized by glued or welded Keder tapes, which are positively received in corresponding receiving areas of the stabilization profiles. In addition, however, is also intended to other connection options, for example via a terminal block to easily exchange the flexible or flexible segments in the installed state.

In the case of roller shutters according to the invention, the door leaf is connected to the joint arrangement only via the stabilization profiles, which serve as a wind reinforcement, and which can be realized for example as a hinge band. The lateral edges of the individual slices or door leaf segments can extend over two, three or more articulated members, wherein individual articulated members are only indirectly connected to the door leaf segments or discs via the articulation members directly connected to the stabilizing profiles.

In the context of the invention, it has proved particularly expedient if at least one segment edge is attached to the stabilizing device by means of a clamping member that can be fastened releasably to the stabilizing device and is preferably accommodated at least partially in the stabilizing device and / or delimiting the stabilizing device. In this embodiment of the invention, the individual slices or Torblattsegmente can be particularly easily replaced by the clamping member released from the stabilizer and then the corresponding segment edge is removed from the stabilizer. When both segment edges of a segment with corresponding clamping members are attached to the stabilizer, the corresponding segment can be completely removed from the door panel without compromising the stability of the backbone consisting of the hinge assemblies and the stabilizers.

In a particularly preferred embodiment of the invention, the segment edge between the releasably secured to the stabilizing device clamping member of a sealing strip is arranged so as to ensure a tight transition between the stabilizer and Torblattsegment.

The intermediate hinge points of the hinge assembly and the hinge band are not connected to the flexible material. The hinge or the hinge assembly 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 strap can be carried out arbitrarily in the grid of the hinge points. For different disc heights can be realized. For narrow gates, the number of stabilization profiles or wind stiffeners can be chosen to be smaller, ie the section height can be particularly large during wide gates for stabilization with several stabilization profiles or wind stiffeners can be equipped with smaller section height.

Structurally, it has proven to be expedient if the door leaf has at least two in Torblattbewegungsrichtung successively arranged discs made of flexible material, between which a stabilization profile with two receiving areas for receiving provided on facing disc edges thickenings is arranged. The stabilization profile thus causes the connection between successive discs of resilient material.

As already explained above, it has proved to be expedient in terms of obtaining a stable Torblattkonstruktion when 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 affecting the mobility of the joint arrangement is achieved when the stabilizing device is connected along the hinge axis with at least one, preferably with two provided on opposite side door leaf edges joint arrangements.

In particular, in the case of particularly high and / or wide door leaves, it has proved to be expedient with a view to the desired stabilization if at least one reinforcing strip extending approximately parallel to the lateral door leaf edge and secured to the door leaf is provided. By using appropriate reinforcing strips, which can also be glued and / or welded to the panes of the door leaf, for example, a sufficient overall stability can be achieved even if the material of the pane itself does not bring sufficient bending stiffness.

Similarly as in the case of the roller doors described in DE 10 2009 017 767 A1, a roller door with flexible door leaf according to the invention can be assigned at least one helical guide track for guiding the door leaf movement and for determining the open position of the door leaf, wherein at least one hinge element has a side facing away from the door leaf may have for guiding the Torblattbewegung with the guideway cooperating guide assembly, which preferably has at least one with respect to a parallel to the hinge axes extending roller axis rotatably mounted guide roller, which is preferably received at least in the open position of the door leaf in a guideway.

During operation of 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 track for guiding the Torblattbewegung, it has been shown that at high Torblattgeschwindigkeiten to increased wear of the guideway 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 discussed aspects of the invention, this problem is solved by a gate, in particular roller shutter, with one between an open position in which it at least partially releases a wall opening and above the wall opening forms a multi-layer winding, and a closed position in which it at least partially closes the wall opening, movable door leaf, which is at least partially formed of a flexible material, such as a plastic film, which is characterized essentially in that in a Opening edge leading edge of the door leaf is formed by a non-rotatably connected to the upper edge of a segment of a flexible material in the closed position leading stabilizing device, the rotation with a predetermined by a preferably by guide rails, at least a connected in a curved manner extending guide track cooperating guide assembly, wherein the orientation of the guide assembly follows the course of the guideway.

This solution is based on the recognition that the increased wear observed in the operation of conventional goals at high door speeds is essentially caused by the fact that the upper edge of the flexible material door leaf is deflected out of the door leaf plane in such a manner when entering the spiral guide track initially a bulge of the door leaf takes place inwardly, which merges abruptly in the further course of the opening process in a bulge, which is maintained in the open position. The sudden change of the inner curvature in an outer curvature 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 will cause the observed increased wear.

The non-rotatable connection of the upper edge of a door leaf segment made of flexible material to the stabilizing device forming the edge of the door leaf during the opening movement on the one hand and the non-rotatable connection of the stabilizing device to the guiding arrangement which cooperates with the guide track and whose course follows the other result in the upper edge of the guide rail Torblattsegments of flexible material is forcibly deflected when entering the guide assembly in the spiral guideway to the outside, whereby the Torblattsegment an outer curvature is forcibly impressed. The transfer of this outer curvature of the upper segment in the course of the opening movement is transmitted to the following segments of the door leaf, when the following stabilizing devices are connected between the individual Torblattsegmenten rotatably connected to the leadership to be guided by the guide rollers, the roller axes, as already mentioned above, parallel to the joint axes of the articulated which hinge members, in particular coaxially thereto, can run. Overall, a defined curvature of the door leaf can be ensured in the course of the opening movement.

As a result, excessive loads on the door leaf and the guide rail can be avoided and increased wear can be prevented.

The guide assembly non-rotatably connected to the advancing stabilizer may comprise two, three or more guide pins or rollers disposed one behind the other in the door leaf movement direction and attached to a common support rotatably connected to the advancing stabilizer. By using two, three or more in the Torblattbewegungsrichtung successively mounted on a common carrier and cooperating with the guide rail guide pins or rollers is achieved that the alignment of the guide assembly follows a total of about the curved course of the guideway. In this case, the carrier is preferably attached to a leading in the opening movement of the hinge member, wherein the attachment of the carrier to the hinge member can be rotationally fixed. If the guide arrangement has two, three or more guide rollers arranged one behind the other in the door leaf movement direction, each of the roller axes running parallel to the axes of articulation can be rotatably connected to the common carrier connected in a rotationally fixed manner to the advancing stabilization device.

In addition to the usual Spiralführungsbahn also alternative tracks such as an oval spiral horizontal deflection or vertical guidance depending on the space required on the building can be realized.

In all embodiments of the invention, it has proven to be advantageous if at least one hinge member is associated with an attachable in the closed position to a boundary surface of the door leaf seal assembly. To be particularly favorable, it has proven in this context, when the individual, the hinge members associated seal assemblies in the closed position form a continuous sealing strip in the manner of a chain seal, to which individual segments or slices of the door leaf or the lateral edges of the door leaf in total can create closed state.

In the context of the invention is also intended to those embodiments in which the seal assembly to the outside facing away from the door to be closed space outer boundary surface of the door leaf applies. However, it has been shown that a particularly reliable seal can be achieved if the seal arrangement adjoins 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 in turn is based on a detailed investigation of the kinematics of the Torblattbewegung when entering the helical track back. In this phase of the movement, the door leaf is forced outwards and can thus strike against an externally applied thereto sealing arrangement, which in turn can lead to increased wear of the door leaf itself and the seal assembly. However, if the seal assembly comes into abutment with an inner boundary surface of the door leaf, this cause of wear is eliminated and achieved as a whole an improved seal.

As already mentioned above, it has proven to be expedient if the joint assemblies associated with the seal assemblies in the closed position form a continuous sealing strip in the manner of a chain seal. In this context, it is also intended to those embodiments in which the seal assemblies have at least one over two, three or more joint members extending sealing element, so that a complete seal over the corresponding number of joint members. In this case, the connection of this sealing element to the hinge members via separate, attached to the hinge members fasteners done. Alternatively or additionally, the seal receptacle can also be integrated into the individual joint members. In this case, a composite material made of plastic and metal for producing the joint members with possibly integrated sealing elements are used.

Gate leaves inventive gates can be moved with a particularly high door leaf speed in the open position. However, care must be taken to ensure that when the open position and corresponding braking of the door leaf are reached, there is no distortion 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 useful in this context when a in the course of the opening movement to a trailing edge in the opening movement of the door leaf biasing device for braking the opening movement and providing a door leaf urging the open position to the closed position biasing force is provided. By coupling the pretensioning device to the trailing edge of the door leaf, it is ensured that the lower region of the door leaf in the closed position is prestressed in the desired manner with the edge trailing during the opening movement when the opening position is reached with the aid of the pretensioning device. Thus, distortions of the door leaf can be avoided in the area of the trailing edge during the opening movement. At the same time can be provided by the biasing device for initiating a closing advantageous Losbrechmoment because the door leaf is biased with the optionally indirectly on its trailing edge in the opening movement biasing device is biased into the closed position. In the context of the invention, it has proved to be particularly advantageous if the biasing means comprises a tensioning spring which extends approximately in the direction of gravity and is designed, for example, as an expander rope, that is to say at least partially made of an elastomeric material, the upper end of which is in the course of the opening movement of an in the Detected area of the attached during the opening movement trailing edge of the door leaf driver and is carried. Additionally or alternatively, the use of tension springs is also intended.

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

The roller door shown in Fig. 1 comprises a generally designated 10 door leaf, which is formed from discs 12 of flexible, transparent material, which are connected to each other via stabilizing profiles 40. At the lateral edges of the door leaf 10 joint arrangements in the form of hinge bands 20 and 30 are arranged, which are connected via the stabilizing profiles 40 with the door leaf 10. The hinges have at the joints between the individual hinge members on their side facing away from the door leaf 10 guide rollers 22 and 32, with which the Torblattbewegung can be performed using suitable guide rails.

According to FIG. 1, the hinged bands 20 and 30 forming a push-pull bandage are formed by hinge members 26 and 36, respectively, which have at their one end a fork-shaped receptacle or comparable design into which a pin of an adjacent hinge member engages. Fork and pin are penetrated by a common hinge pin, so as to effect an articulated connection between successive hinge members. The roller axes of the guide rollers 22 and 32 extend parallel to the hinge axes, preferably collinear with it. Likewise, the stabilization profiles 40 designed as extruded aluminum profiles run parallel to the joint axes or roller axes. The connection of the stabilization profiles 40 to the joint arrangements 20 or 30 can take place in the pivot points of the hinge bands.

According to FIG. 2, a roller shutter according to the invention has a helical guide track 100, into which the guide rollers 22 and 32 mounted on the hinge straps 20 and 30 respectively retract upon reaching the open position. In Fig. 2, the hinge members 26 and 36 are hidden in the region of the spiral guide track so as to achieve a better representation of the door panel itself. It can be seen that discs 12 of flexible material readily conform to the desired spiral shape. For this purpose, it is also not necessary that the discs 12 are themselves connected to the hinge bands. Rather, it is sufficient if only the stabilization profiles 40 between the individual disks are connected to the joint arrangements in the form of the hinge bands 20 and 30 respectively. It can also be seen that the individual sheets of flexible material over a considerable height of the door leaf can extend. This is a particular advantage compared to conventional lamination doors, which allows for minimizing the spiral diameter.

According to FIG. 3, the disks 12 have thickenings formed by welded-on piping 14 on the disk edges running perpendicular to the lateral edges, which thickenings are accommodated in the receiving regions 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 the implementation of the discs 12 with glued Kederfahnen, but not the implementation of the thickenings or piping 14 allow. As a result, a secure connection of individual panes over the stabilization profiles 40 is achieved. However, no tensile or shear forces must be transmitted via this connection. These are transmitted via the hinge bands 20 and 30, respectively.

4, the connection of the hinge straps 20 and 30 via the stabilizing elements 40 by means of a colinear to the roller axis of the guide rollers 22 and 32 extending screw, which is secured with a lock nut 50. The screw engages in a corresponding recess 52 (see Fig. 3) in the stabilizing profiles 40 a. 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 extend approximately collinear.

The embodiment of the invention illustrated in FIG. 5 differs essentially from the embodiment explained with reference to FIG. 3 in that the stabilizing profile 140 has two receiving areas 142 and 144 which are suitable for receiving a clamping member 150 (see FIG Sealing strip 160 (see Fig. 5c) are designed. In the assembled state, the clamping member and the sealing strip are received in the receiving areas 142 and 144, wherein a segment or disc edge between the clamping member 150 and sealing strip 160 is arranged (see Fig. 5d).

The embodiment of the invention illustrated in FIG. 6 differs essentially from the embodiment explained with reference to FIG. 5 in that the clamping member 250 constitutes a boundary of the stabilization device 240. For this purpose, the clamping member 250, as shown in Fig. 6, clipped into the stabilizing profile 240. Also in this embodiment of the invention, the edge of the disc 212 is disposed in the assembled state between the clamping member 250 and sealing strip 260, wherein the sealing strip 260 is received with a mounting bead in a corresponding receptacle of the stabilization profile. Fig. 7a) shows executed as aluminum extruded hinge members 126, wherein the connection of the rollers 122 is shown via slide bearing to the hinge assembly.

Fig. 7b) shows as a plastic injection molding hybrid executed joint members with a plastic injection molding jacket and a sheet steel core.

In the embodiment of the invention shown in Fig. 8, a seal assembly 370 is mounted on hinge members 360. The seal assembly 370 has a sealing strip 380, which form a continuous seal in the closed state, because the sealing strip 380 extends over a plurality of hinge members 360. On the sealing strip, an outer boundary surface of the individual segments or slices of the door leaf in the closed state can be applied.

In Fig. 9, the connection of the stabilizing profiles 240 is illustrated to the joint assembly by co-linear extending to the hinge pins bolt, on the one hand, the hinge assembly, the stabilizing profile and on the other hand, the hinge assembly, the guide rollers are arranged.

In the case of the embodiment of the invention shown in FIG. 10, the edge of the door leaf leading in the case of an opening movement is formed by a stabilizing device 40, which is connected in a rotationally fixed manner to a guide arrangement, indicated as a whole by 60. The guide assembly comprises an approximately U-shaped holder 62. An outer leg of the U-shaped holder 62 is attached via a bolt 64 and a locking screw 66 to the stabilizer 40. Bolt 64 and screw 66 are spaced apart in the direction indicated by the arrow P Torblattbewegungsrichtung. In this way, a rotationally fixed connection of the holder 62 to the stabilizing device 40 is realized. On the holder 62 two successively arranged in Torblattbewegungsrichtung P guide rollers 22 are mounted, each of which with respect to parallel to the hinge axes of the hinge or hinge members 26 extending roller axes is rotatably mounted on the holder 62. The holder 62 is otherwise rotatably connected to the leading in the opening movement hinge or joint member 26.

In Fig. 10b, the equipped with the guide assembly 60 door leaf is shown when entering the spiral guide track. Due to the positive guidance of the holder 62 rotatably arranged on the guide rollers 22 rotatably connected to the guide assembly 60 stabilizing device 40 and thus leading to the opening movement rotationally fixed edge of the disc 12 is carried along or aligned according to the guideway and the disc 12 so zwangsweise outward arched. This curvature is transferred to the subsequent slices of the Torblatt, because the between the individual slices 12 provided stabilizing means 40 with respect to a co-linear to the hinge axes of the hinge members extending roller axis rotatably connected to the guide rollers 22 are connected. By this forced operation of the guide assembly 60, the guide rollers 22 mounted thereon, the non-rotatably connected stabilizing device 40 and the non-rotatably connected to the stabilizer 40 upper edge of the leading edge during the opening movement or in the opening movement leading disc 12 is an uncontrolled turning of the disc 12 and the subsequent discs 12 avoided between an inner curvature and an outer curvature and thus increases the wear resistance of a door according to the invention.

Incidentally, the embodiment of the invention illustrated in FIG. 10 differs from the embodiments of the invention illustrated with reference to FIGS. 1 to 4 in that the individual joint members have two fork-shaped receptacles on one side and the fork-shaped receptacles of an adjacent joint member on their other side have engaging pins. As a result, an improved torsional rigidity of the joint arrangement is achieved.

In the embodiment of the invention shown in FIG. 11, a sealing arrangement 470 lying in the closed position on a surface of the panes 12 facing the door leaf is shown. 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 provided at its edge facing the inner boundary surface of the disc 12 with a hollow chamber seal 474, by which a particularly reliable sealing effect can be achieved. The seal profile 476 of the seal assembly illustrated in Figure 11 may extend over two, three, or more hinge members extending between successive stabilizers 240. Overall, the seal assembly 470 extends in the Torblattschließstellung approximately in the direction of gravity.

In Fig. 12 is a perspective view from above of one of two lateral frame profiles 600 of a gate according to the invention is shown. The side frame profile 600 has a channel 610 extending in the direction of gravity, in which a tension spring 500 is received, of which in Fig. 12, the upper end can be seen. At the upper end of the tension spring 500, an exposed boom 520 is attached to which a driver (not shown) attached to the follower during the opening movement of the lower link 26 engages in the course of the opening movement. With the help of the driver, the boom 520 and thus also the upper end of the tension spring 500 in the course of the opening movement carried upward and so the tension spring 500 are 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 which promotes the initiation of a closing movement is made available.

The invention is not limited to the embodiment explained with reference to the drawing. Rather, it is also thought to provide additional stabilizing strips parallel to the lateral edges of the door leaf, so as to achieve additional stabilization with respect to wind loads. Also, in the described embodiment in the form of hinge straps executed push-pull-bandages can be designed differently. The connection of the stabilizing elements with the push-pull-bandage can also be articulated while avoiding a rigid connection. This creates a floating bearing that helps to prevent transmission of torsional forces from the wound segments to the push-pull bandage.
