Description

Gate, in particular spiral door

The present invention relates to a door, in particular a spiral door, with a starting from a closed position in the course of an opening movement in a multi-layer winding position or opening position movable door leaf and a guide arrangement with a spiral guide track section for guiding the opening movement in the region of the lateral edge of the door leaf. Gates of this type can, for example, for closing garages and

Hall entrances, used to close passages between industrial halls or to separate various areas within an industrial hall.

In this case, the door leaf in the closed position is usually arranged approximately in a vertical plane, wherein the lower edge of the door leaf rests against the bottom of the opening to be closed and the door leaf closes the opening. Starting from the closed position, the door leaf in the course of an opening movement against the gravity direction upwards in an open position is movable. In the course of the opening movement, the door leaf is wound up into a multi-layered winding. The opening position in which the door leaf is arranged in the form of the multi-layered winding is referred to below as a "multi-layer winding position." In this case, the multi-layered winding can circulate a winding shaft in a spiral manner, which is usually arranged behind the lintel forming the upper edge of the opening to be closed This ensures a space-saving accommodation of the door leaf in the open position. The door leaf can be formed in the form of a so-called. Tank with a plurality of respect to. Vertically to the direction of movement of the door leaf extending hinge axes articulated interconnected profiles. In cases where there is less to one

burglar-proof completion of the entrance arrives as a quick opening of the door opening, the door leaf may be formed in the form of a flexible web-shaped curtain and consist for example of PVC.

In a roller door described in EP 0 531 327 B1, the door leaf is received in the open position with its lateral edges in guide rails with a spiral guide track section and is supported by these. To produce the articulated connection between the individual profiles of the roller shutter blade, the profiles are at their respective adjacent profiles facing edges

Engaging devices in the form of so-called Einschiebeprofilen equipped.

In conventional scroll or roller doors, the thrust for moving the door leaf to the open position is typically introduced into the door leaf at the lowermost profile of the tank. For example, the thrust of a drive by means of a chain or a toothed belt is transmitted to the lowest profile of the tank, and the door leaf is pushed against gravity in the open position. For this purpose, a side part is provided on at least one side of the door leaf, in which a circumferential chain or a circulating toothed belt is arranged. The power transmission takes place in such linear linear in the vertical direction. This requires a corresponding space requirement laterally of the door leaf.

In other spiral or roller doors, the thrust is using a

telescoping boom introduced into the leading in the opening movement profile of the tank. The winding axis facing away from the end of the spiral cantilever, which is coupled to the leading edge during the opening movement of the tank, it follows the spiral path of the profile. However, such a Torblattführung is very complex and also has an increased space requirement, since the telescopic unit and the drive due to the high torque to be applied are to be highly dimensioned.

In view of the problems described, it is the object of the present invention, a goal, in particular a roll or spiral door to provide, the drive and guide assembly have a reduced footprint, and the door leaf is precisely and reliably movable between the open and closed positions.

This object is achieved by a gate according to claim 1. Advantageous developments are described in the dependent claims. The gate according to the invention has a leading portion in the opening movement, in particular the leading edge of the door panel attached flexible tension member for pulling the door leaf in the multi-layer winding position.

The flexible tension element is attached, for example, to a leading edge of the door leaf and pulls the door leaf from the closed position against gravity in the multi-layer winding position in which the door leaf a winding shaft rotates several times and is arranged in the form of multi-layered coil. If the door leaf is formed as a tank with a plurality of hingedly interconnected profiles, the flexible tension member may be attached to the leading at opening profile, for example. At the lateral edge. If the door leaf is designed as a web-shaped curtain, the flexible tension element can be attached to the leading edge of the curtain during opening or to one side of a curtain reinforcement arranged there.

The flexible tension member is preferably a rope or belt member such as, for example, a belt, a rope, a wire rope, a belt, a belt, a chain or a cable.

Preferably, the flexible tension member is a belt such as, for example, a flat belt, which can be adapted for running on running surfaces of pulleys and / or for winding on a belt pulley.

The invention is based on the knowledge that by the introduction of force into a leading in the opening movement portion of the door leaf, a vertical

Power transmission unit side of the door leaf such as a revolving chain to

Force introduction into the lowest profile is not required. As a result, the side part of the door can be made very space-saving. Furthermore, by shifting the power transmission to the door leaf at its "upper" edge, a crash mechanism can be realized in a simpler manner because of the space saving in the lower area of the door leaf shifts the pusher in the course of

Opening movement due to the spiral course of the guideway portion when winding the door leaf radially from outside to inside, which is why with spiral doors with

Telescopic boom a complex and potentially vulnerable mechanics and a high

dimensioned drive may be required. The present invention is also based on the recognition that a flexible tension member such as a belt for pulling the Torblatt in the winding position due to its flexibility can easily run along a spiral narrowing path, so that when using the flexible tension member no complex mechanism and no large dimensioned drives are required. Rather, a flexible tension element, the door leaf regardless of the course of the guideway of Pull TorLatts along this guideway in the winding position and thereby follow the helical course of the guideway between the region of the force in the door leaf and a storage device, such as a belt pulley, which is wound, for example, as a belt tension element in the course of the opening movement. In a door according to the invention, in particular spiral door, the door leaf is preferably arranged in the multi-layer winding position in the form of a coil with spaced-apart layers. In other words, unlike a simple roller shutter, the individual winding layers of the multi-layered winding are preferably not adjacent to one another. This can reduce the risk of damaging the door leaf when winding and unwinding. For example, have two adjacent winding layers of the

Wickels in the open position a distance of 1 cm or more, in particular 5 cm or more from each other. Adjacent turns of the helical guideway portion of the guide assembly may be spaced correspondingly.

A reliable opening mechanism for opening the door leaf can be provided in that the flexible tension element on the one hand at the leading

Section of the door leaf and on the other hand mounted on a rotatable winding shaft assembly, which is circulated by the door leaf in the winding position in a spiral manner.

The rotatable winding shaft arrangement preferably comprises a winding shaft running perpendicular to the direction of movement of the door leaf, which can be arranged above the opening to be closed by the door leaf and / or behind the lintel of the door opening to be closed. The flexible tension member may be attached to the winding shaft assembly such that it can be wound thereon.

In a preferred embodiment of the invention, the front end of the flexible tension member is at the leading portion of the door leaf and the rear end opposite the front end of the flexible tension member, on the

Attached winding shaft assembly. As the winding shaft assembly rotates, the flexible pulling member is wound onto the winding shaft assembly, thereby pulling on the leading portion of the door sheet so that the door leaf along the spiral guide track portion can be moved to the winding position. Reliable winding and unwinding of the flexible tension element on the

Winding shaft assembly can be ensured by a belt pulley, on which the flexible tension element in the course of the opening movement can be wound up. The belt pulley is preferably non-rotatably connected to a winding shaft of the winding shaft assembly, so that it rotates together with the winding shaft. The belt pulley may have a guide for the flexible pulling element. For example. is the width of the belt pulley to the width of adapted to flexible tension element. In one embodiment, the belt pulley two annularly projecting from the winding shaft collar between which the flexible Zugefelde is wound up.

The belt pulley is preferably attached to a lateral edge portion of the winding shaft. For example, the belt pulley is arranged in an edge portion of the Wicking, which protrudes laterally from the multi-layer winding when it is wound in the open position around the winding shaft. In this way, the flexible tension member can be wound in the course of the opening movement on the belt pulley, without obstructing the forming winding of the door leaf or be hindered by this.

In this context, it should be noted that the gate preferably on both sides (ie on a right side and a left side of the door opening) a

Guiding arrangement having in each case a spiral-shaped guideway section, wherein on each side of the door leaf at least one flexible tension element for pulling the door leaf is arranged in the multi-layer winding position. For example, a first flexible pulling element is attached to a first side of the portion of the door leaf that advances during the opening movement, and a second flexible pulling element is attached to a second side of the portion of the door leaf that advances during the opening movement. As a result, a symmetrical application of force on both sides of the door leaf is possible, and the door leaf can be pulled evenly and without the risk of jamming in the multi-layer winding position. In this case, the winding shaft assembly may have a winding shaft with two belt pulleys in two opposite edge portions of the winding shaft.

For moving the door leaf, at least one door drive can be provided. The door drive may be configured to drive the winding shaft assembly so that it rotates about its own axis. In some embodiments, the door operator is on

Pipe drive, which is at least partially disposed in the interior of the winding shaft.

For example, the door drive is a tubular motor arranged in the winding shaft. A tubular drive has the advantage that the side of the winding shaft less space for a

Drive unit is required, so that a compact and space-saving design can be provided.

Alternatively, the door drive may be an axially flanged to the winding shaft drive such as a plug-on drive. Typically, an axial on the winding shaft

arranged door drive with respect to a tubular drive increased torque provide, so that such a drive, for example, can be used for larger gates.

Preferably, the flexible tension element is guided in the course of the opening movement on an approximately spiral trajectory. In a first possible embodiment, the flexible tension element is, for example, guided by the helical guide track section of the guide arrangement through which the door leaf is also guided.

In a particularly preferred embodiment, the flexible tension element is guided on a spiral trajectory, the course of which is essentially modeled on the course of the spiral guide track section of the guide arrangement.

For example, the spiral trajectory for the flexible tension element extends next to the spiral guide track section for guiding the door leaf, for example laterally offset thereto. In this way, the flexible tension member can pull the door leaf without collision along the spiral guideway portion in the multi-layer winding position. The turns of the spiral trajectory can also be between those of

Guideway be arranged.

Preferably, the flexible tension element is on a variety of

preferably guided and supported rotatably mounted pulleys, which are arranged such that they provide the approximately spiral path for the traction element tensile. When the flexible tension element is guided outside on the rolling surfaces of the deflection rollers, it is arranged approximately in a spiral shape. For example, the axes of rotation of the deflection rollers are arranged approximately on a spiral path, the course of which approximately corresponds to the course of the spiral guide track section and / or is arranged substantially parallel or offset thereto or runs between the turns of the guide track.

The flexible tension element, for example the belt, runs between two adjacent ones

Pulleys each linear. The more pulleys are therefore provided to form the spiral track, the "rounder" is the resulting spiral shape of the flexible tension member in the open position of the door leaf.

In some embodiments, 10 or more, in particular 20 or more deflection rollers are provided for guiding the flexible tension element on the approximately spiral trajectory. For example, two, three or more (or "n") pulleys are each arranged along a straight radially outwardly extending from the winding shaft as a center straight line, wherein each of these two, three or more (or "n") pulleys of a screw winding associated with the spiral track. In this case, the door leaf of the guided along the spiral trajectory flexible tension element in a winding layer with two, three or more (or "n") winding layers are pulled.

Two deflection rollers adjacent to one another along the path of the track can be arranged at an angle of 60 ° or less, in particular 45 ° or less, with respect to the winding shaft. For example, six or more, in particular eight or more pulleys of a screw winding associated with the train path and arranged along an arc around the winding shaft as the center. The arcs may be circular arcs of constant radius or arcs with a gradually decreasing radius from pulley to pulley. In this context, it should be noted that a helical path is generally understood to mean a guideway which runs around the winding shaft as a center in several turns and whose distance from the winding shaft thereby decreases from turn to turn. So a spiral is not necessarily a circular spiral or a round spiral. It is also intended for the use of oval spirals according to EP 0 531 327 B1, in which arcuate portions are connected in the manner of an oval by approximately rectilinear sections with each other.

In the case of three screw windings of the spiral trajectory, each with eight at an adjacent angle of 45 ° arranged pulleys results, for example, a total of 24 pulleys, which provide the spiral trajectory. In other embodiments, more or less than 24 pulleys may be provided.

In the closing position of the door leaf, at least part of the flexible tension element is unwound from the belt pulley and runs along the spiral trajectory on outer rolling surfaces of the plurality of deflection rollers. The door leaf is arranged substantially vertically and does not or only insignificantly in the spiral

Guideway section of the guide arrangement.

In the course of the opening movement of the door leaf, the door leaf is pulled by the flexible tension element along the spiral-shaped guide track section, the course of which can substantially correspond to the course of the spiral path of the flexible tension element. In this case, the flexible tension element can be wound onto a belt pulley.

In the open position of the door leaf, no flexible tension element is guided at least on the outer deflection rollers remote from the winding shaft, since this is at least partially wound onto the belt pulley. Instead, grab here at the side edge the gate sheet provided guide elements in the spiral guide track portion of the guide assembly a.

In a particularly preferred embodiment of the invention, the plurality of deflection rollers in the region of the lateral edge of the door leaf on the side facing away from the door leaf of a guide slot of the guide arrangement is held. The

Guide slot may be at least partially formed spirally and form the spiral guide track section. The flexible tension element can be fastened to a guide element of the door leaf engaging in the guide slot. As a result, the door leaf can be accurately and accurately pulled by the flexible guide element along the spiral guide slot.

Accurate and trouble-free guidance of the door leaf along the guide arrangement can be ensured by a multiplicity of guide elements projecting on the lateral edge of the door leaf and engaging in the guide arrangement. The

Guide elements can be rotatably mounted on the lateral edge of the door leaf and, for example, be designed as roller or pin elements.

In a particularly preferred embodiment of the invention, the guide elements of the door leaf are guided in the course of the opening movement of the door leaf in the spiral guide track section. The spiral-shaped guide track section can be designed for this purpose as a spiral guide slot, whose

Slot width can be adapted to a width of the guide elements. To one

To avoid sliding out of the guide elements from the guide slot, a section of the guide elements extending through the guide slot can each be widened.

The spiral guide track section may be formed by a helical guide slot formed in a guide plate. The guide plate may be a lasered sheet metal with guide slot in which formed as a roller elements

Guide elements of the door leaf run. In a first possible embodiment without pulleys and the flexible tension element in the guide slot of

Leadership led. However, this can lead to increased wear of the flexible tension member by friction. Therefore, in a preferred embodiment of the invention, the plurality of pulleys are provided, which are arranged such that they provide a track of the guide slot replicating train path for the flexible tension member.

Preferably, the flexible tension element is attached to the leading in the course of the opening movement guide element of the door leaf. In particular, this is flexible Pulling element attached to a portion of the leading guide element of the door leaf, which passes through a guide slot of the guide arrangement. The flexible tension element and the deflection rollers are preferably protected behind a

Guide plate of the guide assembly, for example. Arranged on a side facing away from the door leaf of the guide slot formed in the guide plate. This allows

Prevents damage to the flexible guide element and a uniform guidance of the door leaf along the guide slot can be made possible.

As already mentioned above, the guide arrangement can be equipped with a guide slot which is preferably produced by laser machining

Have guide plate. Additionally or alternatively, the guide arrangement can have a guide rail closed on the side facing away from the guide slot by means of a rail wall, in particular a profiled or extruded steel, aluminum and / or plastic rail, which optionally extends in a spiral shape. to

Providing a smooth bearing surface for guide elements of the door leaf and / or the flexible tension element while ensuring accurate guidance of the

Torblattbewegung using a precise guide slot, the guide rail can be executed as a G-rail and arranged between the guide slot and the rail wall, possibly having a spiral circumferential tread for a guide element of the door leaf. Additionally or alternatively, a deflection roller for the tension element and / or a rotatable about a fixed axis guide roller for the door leaf may be provided, which may be included in a running as a C-rail guide rail, if necessary.

As it has proven particularly useful when the tread is

extending from the guide slot in the direction of the rail wall and ends at a distance in front of the rail wall. In this case, there still remains enough space between the tread and the rail wall for the accommodation of a deflection roller for the optionally executed as a belt tension element.

The power transmission via the spiral-shaped flexible tension element can be coupled with different Torblattvarianten.

In some embodiments, the door leaf is an at least partially flexible curtain, preferably a sheet-like plastic. The hanging is not

necessarily completely flexible, but may have a plurality of flexible sections between which stiffeners may be arranged, which may serve, for example, the wind protection. The curtain can at least partially consist of track elements made of polycarbonate (PC). A lightweight door leaf can be opened quickly and is inexpensive to produce and transport. For example, the gate can be designed as a high-speed door which, for example, can close a passage between two sections of a hall. A trained as a flexible curtain door leaf can be repeatedly bent from a substantially planar position in a multi-layered winding position and back to the flat position. It can be arranged on the lateral edges of the hanging hinge hinges, which are coupled to stabilization profiles of the blind.

In a particularly preferred embodiment, the door leaf is designed as a shell made of aluminum and elements made of polycarbonate.

The stability and burglar resistance of the door can be improved by the fact that the door leaf is a tank with a plurality of, for example, hinges or hinges hingedly interconnected rigid profiles. For example. the door is designed as a roll-up door or spiral door with a lamellar armor. Due to the hinged connectors of the profiles, the door can move from a level position to the multi-level

Changing position and be brought back into the flat position.

In the context of the invention is also intended to the execution of gates, in which the door leaf consists of a combination of rigid profiles and a compliant curtain, wherein the flexible curtain especially in the area of the at

Closing movement leading edge of the door leaf can be provided.

In all embodiments of the invention, an elastically deformable stabilizing element may be provided on the leading edge during the closing movement of the door leaf, in which the restoring force acting in a direction opposite to the closing direction of the stabilization element is smaller than that of a deformation of the stabilizing element in a transverse thereto, in particular approximately perpendicular to the closing element in the closed position, extending direction counteracting restoring force, so as to reduce the risk of injury in an impact of the stabilizing element on an object or a person in the course of the closing movement.

Corresponding stabilizing elements are described in EP 1604091 B2. The disclosure of this document is hereby incorporated by reference into this description with regard to the execution elastically deformable stabilizing elements. Accordingly, the stabilizing element may have an embedded in an elastomeric material leaf spring with aligned perpendicular to the closing direction of the main surface.

According to a further aspect, the present invention relates to a method for opening a gate, in particular a roller shutter or spiral door. According to the

A method according to the invention is a door leaf by means of a flexible tension element of a Closed position pulled into a multi-layer winding position. The tension element can be designed as a belt. The flexible tension member is attached to a leading portion of the door leaf when opening the door leaf. In the region of its lateral edge, the door leaf can be replaced by a guide arrangement with a spiral

Guideway section be performed.

In a preferred embodiment of the invention, the flexible tension element is guided in pulling the door leaf in the multi-layer winding position on an approximately spiral-shaped track. The spiral trajectory of the flexible tension element can simulate the course of the spiral guide track section of the door leaf. In this way, the flexible tension member can pull the door leaf without collision along the spiral guideway portion in the multi-layer winding position.

Preferably, the flexible tension element is guided on a plurality of deflection rollers, which are arranged such that the flexible tension member is arranged approximately helically when it is guided outside on the rolling surfaces of the deflection rollers.

For example, the axes of rotation of the deflection rollers are arranged on a spiral path, the course of which can essentially correspond to the spiral-shaped guide track section and / or which is arranged substantially parallel or offset therefrom.

In the course of the opening movement, the flexible tension element is preferably wound onto a rotating winding shaft arrangement. In particular, the

Winding shaft assembly a belt pulley on which the flexible tension element is wound.

Is arranged substantially vertically, wherein the lower Torblattrand rests on the bottom of the door opening to be closed.

The door leaf 20 can be moved against the direction of gravity in an open position in which the door leaf 20 is arranged in the form of a multi-layered roll in a multi-layered winding position. The individual winding layers preferably do not touch each other in the winding position and / or in the course of the opening movement, in order to avoid damage to the door leaf and to ensure exact guidance from the closed position into the gate

To allow opening position.

The door leaf 20 has a leading in the course of the opening movement

Door leaf section 24 and a trailing in the course of the opening movement

Torblattabschnitt on. Furthermore, the door leaf has two lateral edges 22, on which the door leaf 20 is guided in each case by means of a guide arrangement 30, which may have a guide slot or a guide rail. In the closed position shown in Fig. 4, the door leaf in the region of its lateral edges 22 is approximately vertical

Guided track sections of the guide assembly 30, the only through

dashed lines are indicated. The guide assembly 30 has a helical guideway section 32 in which the lateral edges 22 of the door leaf are guided during movement in the multi-layer winding position. The spiral guide track section 32 is also indicated in FIG. 4 as a dashed line.

In the multi-layer winding position, the door leaf 20 surrounds a

Winding shaft assembly 50 in the form of a multi-layered coil. The winding shaft assembly 50 may be one above the door opening and / or behind a fall of the door opening in

Have substantially horizontally extending winding shaft. The winding shaft assembly 50 can be driven by means of a door drive, which may be formed, for example, as a tubular motor. Fig. 1 shows a schematic view of an upper portion of a gate 10 according to the invention, as shown by way of example in Fig. 4. It is the

Guide assembly 30 for guiding the door leaf 20 for a better

Clarity in Fig. 1 omitted. The guide assembly 30 is shown separately in Fig. 2. FIG. 3 shows the upper portion of the door 10 according to the invention from FIG. 1 with the guide arrangement 30 of FIG. 2 attached thereto.

In Fig. 1 and Fig. 3, the door leaf 20 is shown in the course of an opening movement in which the door leaf is brought up into the multi-layer winding position. For this purpose, a flexible tension member 40 such as a belt for pulling the door leaf 20 is mounted in the multi-layer winding position at the leading portion 24 of the door leaf 20.

In the embodiment shown in Fig. 1, the door leaf 20 is formed as a partially flexible curtain 28, which may have perpendicular to the direction of movement of the door leaf extending stiffeners that can serve the wind protection. The belt may be at a side edge portion of the leading during the opening movement

Torblattversteifung be appropriate. The lateral edges are designed as hinges, which are attached to the stiffeners, as described in EP 16 002 133.3.

The flexible tension member 40 is guided by a plurality of pulleys 45 along a spiral track 42. The course of the spiral trajectory 42 substantially corresponds to the course of the spiral guide track section 32 (see FIG. 2), along which the leading section 24 of the door leaf 20 in the course of

Opening movement of the door leaf is performed.

In the embodiment shown in FIG. 1, twenty or more deflection rollers 45 are for guiding the flexible tension member 45 along the spiral trajectory 42

intended. In an alternative embodiment, the flexible tension member 45 may also be slidably guided on a continuous spiral track, for example on the helical track portion 32 of the guide assembly 30. The guide of the flexible

Tension member 40 by means of the preferably with respect to coaxial with hinge axes of

However, hinges 22 extending axes of rotation rotatable pulleys 45 reduces the wear of the flexible tension member 40 and the pulling force required to pull the door leaf in the open position.

The deflection rollers 45 may be arranged such that their axes of rotation in

Essentially lie on a spiral path with two, three or more turns.

Preferably, each of the turns are associated with six, eight or more pulleys, so in that through the deflection rollers 45, a track simulated for a circular spiral can be provided for the flexible tension element. A high number of small spaced Umlenkroil results in that the spiral trajectory 42 the

preferably formed as a circular spiral spiral track section 32 is particularly close, whereby the guidance of the door leaf improved and the required traction can be reduced.

As shown in Fig. 1, the flexible tension member 40 may be attached on the one hand to the leading portion 24 of the door leaf 20 and on the other hand on a belt pulley 55 which is rotatably held on the winding shaft 52 of the winding shaft assembly 50. The belt pulley 55 is adapted to the flexible tension member 40 that this can be wound without the risk of crossovers or jamming on the belt pulley 55 and unwound from this. In Fig. 1, an optionally arranged at the opposite end of the winding shaft 52 second belt pulley is shown on which an optional second flexible tension element is wound during movement of the door leaf in the open position. By a second flexible tension element is a symmetrical

Force transmission into the door leaf guaranteed.

A trained as a tubular drive door drive for driving the winding shaft 52 may be disposed in the winding shaft 52. Alternatively, a door drive can be provided, which is arranged in the axial extension of the winding shaft 52 and, for example. Is designed as a plug-on drive.

FIG. 2 shows a schematic view of the helical guideway portion 32 of the guide assembly 30. The helical guideway portion 32 may be formed as a helical guide slot 34 inserted in a guide plate.

Guide elements 25 of the door leaf can engage in the guide slot 34 or

pass through this, so that the door leaf along the spiral guide slot 34 can be guided in the multi-layer winding layer. As shown in FIG. 3, the spiral guide track section 32 is disposed on one side of the door leaf 20 such that its central opening is penetrated by the winding shaft assembly 50.

In Fig. 1 is particularly well seen that the guide elements 25 of the door leaf on the lateral edge 22 of the door leaf 20 projecting rotatable pin or roller elements. In Fig. 3 it is shown that these guide elements 25 can pass through the guide slot 34 of the guide assembly 30, so that their front portions in a space between the guide plate of the guide assembly 30 and a

Sidewall are included. In this space, the pulleys 45 may be rotatably supported for the flexible tension member. The pulleys 45 are, for example. In Area of the lateral edge 22 of the door leaf 20 on the side facing away from the door leaf of the spiral guide slot 34 of the guide assembly 30 is held.

In Fig. 1 it is further shown that the flexible tension member 40 is attached to the moving in the course of opening opening leading guide member 26 of the door leaf in a portion which passes through the guide slot 34.

As can be seen from Fig. 3, the door leaf 20 is arranged in the multi-layer winding position in the form of a coil with spaced-apart layers. The distance of the layers of the door leaf in the open position substantially corresponds to the distance between adjacent turns of the spiral guide groove 34. In this case, the

Hinge hinges 22 arranged on the curtain side facing the guide plate, while the tension element is arranged on the side facing away from the curtain of the guide plate.

As indicated at 300 in FIG. 4, in all embodiments of the invention an elastically deformable stabilizing element may be provided in the region of the edge of the door leaf leading to the closing movement, in which direction a deformation of the stabilizing element in a direction opposing the closing direction

counteracting restoring force is less than that of a deformation of the

Stabilizing element in a transverse thereto, in particular approximately perpendicular to

Closing element in the closed position extending direction counteracting

Restoring force. Thereby, the risk of damage to objects and / or injury to persons in a Torblattschließbewegung be avoided, while at the same time a sufficient stabilizing effect in a direction perpendicular to the Torblattebene direction is reached.

The use of appropriate stabilizing elements has proved to be particularly advantageous if at least the lower region of the

Torblatts, a deformation permitting, is designed in the form of a compliant curtain. In the case of such door leaves, in which the lower area in the closed position is designed as a flexible curtain, the present invention also provides

Coupling a flexible tension element on the leading part of the opening movement of the door leaf are used with particular advantage, because the drive can be coupled without regard to the stability of the door leaf in the leading in the closing movement area to the door leaf.

In the embodiment of the invention shown in Fig. 5, the

Guiding arrangement as a profiled sheet steel or aluminum extruded profile or Plastic extruded running on guide rail, which is designed as a G-rail. In the guide rail or the guide profile attached to the door leaf 120 guide roller 25 may be added, the roller axis a

Guide slot 134 penetrated. The guide rail 130 is in the plane perpendicular to the trajectory shown in Fig. 5 cutting plane with the exception of

Guide slot 134 executed closed. It has a rail wall 132 arranged on the side facing away from the guide slot 134.

Provided in the guide rail 130 is a running surface 140, which extends from the guide slot in the direction of the rail wall 132 and extends essentially flat or spirally. This tread 140 extends approximately parallel to the direction of movement of the door leaf 120 and serves as a support for the mounted on the door leaf 120 rollers. During the opening or closing movement the roll

Casters 125 on the tread 140 of the guide rail 130 from.

Between the rail wall 132 facing edge of the tread 140 and the rail wall 132 is exemplified a guide roller 145 for a via a holder 126 on the door leaf 120 fastened tension element, such as a belt shown. Instead of the embodiment shown in FIG. 5, while dispensing with a separate deflection roller 145, the guidance of the tension element can take place via the running surface 140. In both embodiments of the invention, a smooth bearing surface for the guide roller and possibly the belt is created by the tread 140. This is an advantage for a quiet door run.

The embodiment of the invention illustrated in FIG. 6 differs essentially from the embodiment explained with reference to FIG. 5 in that, dispensing with a running surface 140, a rotation about a fixed axis of rotation

Guide roller 245 is received in the guide rail 230. This guide roller serves both to guide the tension element and to guide a simultaneously serving as a holder for the tension element sliding element of the door leaf. The guide rails shown in Figs. 5 and 6 may, as mentioned, be designed as profiled steel sheets. But they can also be manufactured as extruded profiles.

In the embodiments of the invention exemplified with reference to FIGS. 5 and 6, various arrangements of the guide elements and deflection rollers can be selected. Guide elements and deflection rollers can be arranged offset from one another in a direction perpendicular to the direction of movement of the door leaf. The guide rollers can have a dual function and at the same time serve to guide the tension element and to guide the door leaf. In Fig. 7a, the course of the guide rails 130 in the embodiment shown in Fig. 5 is indicated semi-perspective. Fig. 7b shows schematically the arrangement of the pulleys 145 for the designed as a belt 160 tension element within the

Guide rails 130. Fig. 8a shows the guide rails shown in Fig. 6 in a schematic perspective view. The guide rollers 245 take on a double function by acting on the one hand as a guide roller for the belt running as a tension element and on the other hand serve to guide the Torblattbewegung. The guide rollers have a receptacle for the guide belt, which is bounded on both sides by a projecting collar. As soon as the guide belt is received in the receptacle, the guide belt and the collar arrangements arranged on both sides form a flat one

Support surface for guiding the door leaf movement. FIG. 8 b schematically shows a possible arrangement of the guide rollers 245 within the guide rails 230.

Instead of a door leaf in the form of a web-shaped curtain can be provided in the form of a tank with a plurality of articulated interconnected profiles Torblatt.

The gate may further comprise a control device for controlling the Torblattbewegung and / or for generating serving to stop the Torblattbewegung control signals, for example. When an obstacle in the path of movement of the door leaf is detected by means of a sensor. The sensor may, for example, comprise a photocell, to which a light beam of a light source may be directed.

The invention is not limited to the embodiment explained with reference to the drawing. Rather, the opening mechanism according to the invention can also be used in other types of gates whose door leaves are movable in a multi-layer winding position. Further, the door leaf may have a plurality of flexible tension members such as straps for pulling the door leaf in the open position. In the present disclosure, in particular, the opening movement for opening the door leaf has been described. Conversely, of course, the door leaf is equally closed again, with the door leaf can move under relaxation of gravity back into the closed position upon release of the tension of the flexible tension element.
