Description

Overhead

The invention relates to a door with a closed from a wall opening closing position in an open position in which it is arranged substantially overhead, along a predetermined path liftable door leaf, the door leaf has two, three or more in the closed position stacked Torblattelemente, and a hinge assembly for such a goal.

Gates of this type are used for example in the form of garage doors, factory gates or hall doors. In this case, the door leaf is usually formed in several parts in the manner described above, wherein it is aligned in the closed position approximately in a vertical plane and circulated by a frame frame. To open such a door, the door leaf is usually moved along a predetermined by a guide rail track in an overhead position in which it extends approximately parallel to the ground and approximately perpendicular to the closable with the door leaf wall opening approximately in a horizontal plane. This opening movement is usually arranged as well as the closing movement of the open position to the closed position with both sides of the door leaf and fixed relative to the wall guide rails of the guide rail assembly and on the Torblatt specified and guided by the guide rails guide elements, such as guide rollers out. The guide rails usually each have a substantially vertically extending straight vertical guide rail segment, in each case a usually substantially horizontally extending horizontal guide rail segment and in each case one the vertical and the horizontal guide rail segment interconnecting arcuate guide rail segment. Such doors, also referred to as sectional doors, have the advantage that, when actuated, the door leaf does not have to be pivoted into the space lying in front of the building to be closed with the door, so that a particularly space-saving operation of the door leaf is possible.

In practice, a number of requirements are placed on the described overhead doors:

On the one hand, the door behind the room behind it should be completely and safely closed. In the open position, the gate should release the clear wall opening as far as possible.

Further, a low lintel height, i. the smallest possible distance between the upper edge of the wall opening and the ceiling of the space to be closed, desired. Especially in privately used garages may require a wall opening form, the height of which corresponds almost to the ceiling.

Also on the kinematic properties of the door leaf in its movement from the open to the closed position different requirements. The movement should be as fast as possible, with the radius of the arcuate guide rail segment limiting the speed. Next, let the door leaf move as smoothly as possible.

In connection with these requirements, a number of possible solutions have been described in the prior art, none of which, however, meets all requirements together.

To achieve a satisfactory closure of the clear wall opening, the individual door leaf elements in the closed position are preferably arranged approximately in a plane. In particular, the trailing leaf element trailing during the closing movement, which is also referred to as the upper door leaf element, and the Torblattelementen arranged underneath lie in a plane. So that the clear wall opening is released as far as possible in the open position, the door leaf element following the opening movement, which is also referred to as the lower door leaf element, should project as little as possible into the clear wall opening in the open position.

If the dimensions of the space to be closed by the door leaf allow it, this goal can most easily be achieved by arranging the arcuate guide rail segment completely in the camber area of the wall opening, and the horizontal and vertical guide rail segments each have at least the length of the entire door leaf height. Then, in the closed positions of the door leaf, the individual door leaf elements can be arranged one above the other in one plane and completely close the clear wall opening. In the open position, all Torblattelemente can be arranged in the horizontal guide rail segment, whereby the clear wall opening is completely released. In practice, the required installation heights and installation depths for such a guide rail arrangement are not given, especially in garages. Next difficult in the open position completely arranged in the horizontal door leaf, the initiation of the closing process considerably. On a gate leaf resting in the horizontal, a breakaway moment must act when the closing movement is initiated. This serves to initiate a movement of the lower edge of the door leaf in the vertical until the located in the vertical section of the door leaf has reached a certain minimum momentum, so that the closing movement of the door leaf can be done independently by gravity, without further external force. If the door leaf is arranged completely in the horizontal, then the required breakaway torque is maximum, and it regularly requires an additional device that initiates the closing movement by a Kraftweinwirkung on the door leaf.

To solve this problem, a pushing device is disclosed in DE 101 01 560 A1 and in US Pat. No. 2,651,360, which triggers and supports the closing movement of the door leaf by a force acting on the upper edge of the upper door leaf element. US Pat. No. 2,651,360 discloses a pushing device with a spring element which is fixedly coupled to the upper edge of the upper door leaf element. In addition, this pushing device is coupled simultaneously with the traction means connected to the lower edge of the lower door leaf element, which raises the door leaf from the closed position to the open position. This design requires complicated assembly and extension of the horizontal guide rail segment to accommodate the pusher therein. These problems are partially solved by the thrust device disclosed in DE 101 01 560 A1, which is not firmly connected to the upper door leaf element but can only be applied to it. The construction of DE 101 01 560 A1, compared to the construction of US 2,651,360, enables easier assembly and requires a shorter horizontal guide rail segment. In both cases, however, an additional assembly step in the installation of the gate is required.

Another problem is in the case where the arcuate guide rail segment is at least partially disposed in the clear opening. This problem occurs, for example, when the lintel height is small compared to the radius of the arcuate guide rail segment. This may be due to the fact that for the space to be closed compared to its total height a large high clearance height is required and thus the lintel height is small. Further, increasing the radius of the arcuate guide rail segment, thereby allowing a higher speed of the door leaf to move from the open to closed positions without disturbing noise, may result in the arcuate guide rail segment being at least partially disposed in the clear opening. Then, among other things, the problem is to achieve a complete closure of the clear wall opening in the closed position.

To solve this problem, WO 97/42387 and EP 0 897 448 B1 disclose a door leaf with a pivoting lever arranged on the upper edge of the upper door leaf element. In the closed position of the door leaf, the guide rollers arranged on the upper edge of the upper door leaf element are arranged in the arcuate guide rail segment. The upper door leaf element is therefore not arranged in the same plane as the Torblattelemente arranged underneath, but is tilted relative to this plane. The pivot lever now allows a tilting of the upper door leaf element relative to the guide rollers on the vertical plane, so that in the closed position, all Torblattelemente can be arranged in a plane.

Such a pivot lever is also disclosed in DE 10 2005 043 229 A1 and in DE 10 2005 008 027 U1 and serves as an adjusting lever for adjusting between a closed position and a pivot position in which the upper door leaf element is pivoted inwardly on the arcuate guide rail segment , The US 5,846,127 discloses a sectional door with such a pivot lever. Another way to achieve a complete closure of the wall opening at a low lintel height is given by the disclosed in DE 101 01 560 A1 guide rail assembly. In this guide rail arrangement, a second horizontal guide rail segment is arranged in the direction of gravity above the horizontal guide rail segment. This second horizontal guide rail segment carries only the upper door leaf element and is located in the lintel area. The guide element arranged at the upper edge of the upper door leaf element is arranged in the closed position of the door leaf in the second horizontal guide rail segment, so that the lower edge of the upper door leaf element with the door leaf element underneath is arranged in a plane. However, this also referred to as Niedrigsturzbeschiag guide rail assembly requires two horizontal guide rail segments and is therefore expensive to install and generates additional costs.

In some cases, the lower door leaf element protrudes in the open position into the clear wall opening. This may for example be due to the fact that, as just explained, the arcuate guide rail segment is at least partially disposed in the clear wall opening and the length of the horizontal guide rail segment is shorter than the height of the door leaf. However, this arrangement may also be due to the fact that the traction means arrangement designed to lift the sectional door from the closed position into the open position can not completely lift the lower door leaf element into the horizontal plane. Such Zugmittelordnung generally consists of a traction means, for example in the form of a pull rope or a pull chain, which is connected at its one end to the lower edge of the lower Torblattelements, and the other end is coupled via guide and / or pulleys to a pulling mechanism. The guide and / or deflection rollers are generally arranged under the ceiling, and such an arrangement therefore does not allow complete lifting of the door leaf in the horizontal plane. The lower edge of the lower door leaf element is typically located in the arcuate guide rail segment and blocks a portion of the clear wall opening. An intrusion of the door leaf in the clear wall opening but may also be intended to reduce the required breakaway torque when initiating the opening movement, but also in this case, an undesirable reduction of the clear wall opening is to be accepted.

To solve this problem, the FR 2 694 331 A1 discloses a second vertical guide rail segment, which leads into the lintel area to that at the lower Edge of the lower guide rail segment mounted guide element to lead into the lintel area. Thus, the clear wall opening is optimally released. However, as the lower door leaf element is moved toward the horizontal plane, this design requires a larger breakaway torque to initiate the closing movement.

Another solution to this problem is provided by the sectional door disclosed in EP 1 467 052 A1. In the sectional door disclosed in this document, the lower edge of the lower door leaf member is hinged on each side to a guide member. On the guide element, a traction means is attached to a space to be closed facing side. Each of these guide elements has two rollers, which are guided in the guide rails. To transfer the door leaf from the closed position into the open position, the traction device pulls the door leaf upwards. Upon reaching the open position, the guide rollers are arranged in the arcuate guide rail segment. Due to the articulated connection between the guide element and the lower edge of the lower door leaf element, this lower edge tilts in the open position in the direction of gravity down. Due to the interaction of the traction means and the guide element connected in an articulated manner to the lower door leaf element, the lower edge of the lower door leaf element can be raised particularly far upwards. However, since the lower edge of the lower door leaf element tilts down in this construction, the clear wall opening is not optimally released.

In view of these problems in the prior art, the object of the present invention is to develop a conventional sectional door in such a way that its kinematic properties are improved and the requirements for the dimension of the space to be closed are lowered.

According to the invention, the object is achieved in that a lower in the closed position and trailing edge of the door leaf when reaching the open position by a pivoting movement of this edge having lower Torblattelements with respect to a door in the closed position above Torblattelement with respect to the predetermined path is separately raised.

The invention is based on the finding that the clear wall opening in the open position can be further released by a separate lifting of the trailing edge of the door leaf during the opening movement when reaching the open position than in conventional sectional doors. The lower edge of the door leaf then protrudes less far into the clear wall opening than is the case with conventional sectional doors. The passage height of the wall opening in the open position of the door leaf is thereby increased.

Furthermore, in the case of a gate according to the invention, an arcuate guide rail segment with a larger radius can be used in comparison to a conventional gate with the same predetermined clearance of the clear opening. This allows a faster and quieter movement of the door leaf.

In the following, the door leaf element leading in the opening movement / following in the closing movement is referred to as the "upper door leaf element." The door leaf element following the opening movement / leading in the closing movement is referred to as the "lower door leaf element". If further door leaf elements are arranged between the upper and the lower door leaf element, these are referred to as "intermediate elements".

In a sectional door according to the invention the lower edge of the lower door leaf element does not follow the predetermined path upon reaching the open position, which describes at least one of the intermediate elements in the transition from the closed position to the open position, but the lower edge of the lower door leaf element is when reaching the open position in comparison to the door leaf elements arranged above can be lifted separately. The lower door leaf element can thus be moved in the direction of the plane in which at least the intermediate elements are arranged. This level is overhead. This plane can be approximately parallel to the horizontal plane. The lower door leaf element can be arranged completely in the open position in the plane of the intermediate elements, and thus can lie completely in the lintel area. Thus, the clear wall opening is completely released. However, the lower edge of the lower door leaf element can also block a region of the clear wall opening.

Next can be generated by the separately liftable edge necessary for the initiation of the closing movement breakaway torque. In the open position of the door leaf, the separately elevatable edge of the lower door leaf element is further raised in comparison to the lower edge of a conventional sectional door. This additional potential energy is converted into additional kinetic energy during the transition to the closed position, whereby the initiation of the closing movement can be facilitated and / or made possible. In one embodiment of the invention, the gate has a first elevating means urging the separately elevatable edge of the lower door leaf element in the transition from the open position into the closed position into the predetermined path. This allows a controlled movement of the door leaf in the transition from the open position to the closed position along the predetermined path can be achieved. In addition, the first biasing means may be for generating the breakaway torque required to initiate the closing movement, as it urges the lower edge of the door leaf in the direction of the predetermined path. The first biasing means may be arranged at the lower edge of the lower Torblattelementes. But it can also be arranged at a different location of the sectional door.

A further embodiment of the door according to the invention is characterized in that, in the closed position of the door leaf, a second pretensioning device counteracts a movement of the separately liftable edge in a direction orthogonal to the door leaf plane. The second biasing device may be the same as the first biasing device. But it can also be different from the first biasing device. The second biasing means may be disposed at the lower edge of the lower Torblattelementes. But it can also be arranged on another area of the sectional door leaf. By the second biasing means, a satisfactory closure of the lower portion of the clear wall opening can be achieved. In particular, the second biasing means can counteract a violent movement of the lower edge of the lower Torblattelements in a direction orthogonal to the Torblattebene, whereby the formation of a gap between the Torblattelement and the wall is prevented. As a result, the burglar resistance can be improved in the closed space with the sectional door. In addition, a z. B. caused by wind movement of the lower Torblattelementes be counteracted in a direction perpendicular to the wall opening and an associated noise.

An inventive gate can be guided by a guide rail assembly along the predetermined path. The guide rail arrangement can have two guide rails arranged on opposite edges of the door leaf, and each guide rail can each have at least one vertical guide rail segment approximately parallel to the direction of gravity, at least one guide rail segment running above the head, preferably approximately horizontally, and at least one vertical and overhead having running guide rail segment interconnecting arcuate guide rail segment. The overhead guide rail segment and the arcuate guide rail segment can be separated be formed from each other. The over-head guide rail segment and the arcuate guide rail segment can also be formed in one piece. The overhead guide rail segment can be oriented approximately horizontally. But it can also include an angle α> 0 with the horizontal. Such a guide rail arrangement is particularly suitable when the space to be closed with the door leaf has a high height but a small depth.

In a further embodiment of the invention, the door leaf can be guided along the predetermined path by an interaction of the guide rail arrangement with guide elements arranged on the door leaf. The guide elements may have rollers. At each door leaf element, two guide elements can be arranged. However, more than two guide elements can also be arranged on a door leaf element. The guide elements can be arranged on opposite side edges of a Torblattelements. According to the invention, the guide elements can be arranged in the region of the upper edge of a door leaf element. However, they can also be arranged in the region of the lower edge of the door leaf element, or in any other area on the side edges of the door leaf elements.

In the case of a sectional door according to the invention, at least one guide element can be arranged at the lower edge of this door leaf element on each side of the door leaf element which has a separately liftable edge on each side of a guide rail. As a result, the door leaf can be guided particularly reliably in the predetermined path. At the top of the Torblattelementes additional guide elements can be arranged. As a result, the guidance of the door leaf along the predetermined path can be further improved.

In a further embodiment of the invention, in the open position, the liftable edge of the door leaf element can be further apart in a direction perpendicular thereto from a guide element arranged on this door leaf element than in the closed position and raised upward relative to the guide element. Since the guide element is arranged in the guide rail arrangement, the lower edge of the door leaf can thus be arranged above the guide rail arrangement. In a case where the guide member disposed on the lower door leaf member is disposed in the open position in the arcuate guide rail segment, the lower edge of the lower door panel member may be raised upward in the open position opposite to the arcuate guide rail segment. A further embodiment of a sectional door according to the invention is characterized in that the separately liftable door leaf element is connected to the guide element via a hinge arrangement enabling a change in the distance between at least one guide element arranged on this door leaf element and the door leaf element. The hinge arrangement allows the lower edge of the door leaf to be raised and the edge to be returned to a position in which the distance between the guide element and the door leaf element is minimal.

The hinge arrangement may have a receptacle arranged on the door leaf element. A pivot lever may be pivotally connected to the receptacle. The pivot lever can be connected to a guide element arranged on this door leaf element.

The receptacle may have a receiving base extending essentially parallel to the plane of the door leaf element. The receiving base may be connected to the Torblattelement. This connection can be made for example via a screw connection. The receptacle may further comprise a first and a second receiving side wall which extend orthogonally upwardly from the receiving base to the latter and extend approximately in the direction of gravity in the closed position. The receptacle may be formed, for example, of metal. The receiving side walls and the receiving base may be integrally formed.

The pickup can accommodate the pivoting lever. The pivot lever may be attached to the receiving side walls. The attachment can take place via a shaft extending approximately perpendicular to and between the receiving side walls. The shaft may be mounted in recesses or openings in the receiving side walls. The shaft can be rotatably mounted.

The pivoted lever pivotably coupled to the receptacle via the shaft can extend from the shaft to the lower edge of the door leaf element. The pivot lever may have a pivot lever base and pivot lever side walls. The swing lever base may abut against the receiving base in a state where the swing lever is completely received in the receptacle. The pivot lever base may then extend parallel to the receiving base. The swing lever side walls may become orthogonal extend away from the pivot lever base and extend in a direction connecting the top and bottom edges of the door leaf member.

The pivot lever may be connected to the shaft in a region of a first end via the pivot lever side walls. The first end of the pivot lever opposite the second end of the pivot lever may be connected to a guide element. In a case where the guide member is a caster, the axis of the caster may be disposed in a tubular portion disposed at the second end of the swing lever.

The function of the hinge assembly is as follows: In a guiding position, the receiving base and the pivot lever base abut each other. The guide element is then arranged adjacent to the lower edge of the lower door leaf element. The lower edge of the lower door leaf element is then guided in the path predetermined by the guide rails. During the transition of the door leaf from the closed position to the open position, the pivot lever base can be moved by pivoting the pivot lever relative to the receptacle in a pivot position. In the pivotal position, the lower edge of the lower Torblattelements is moved away from the guide element. The lower edge of the lower Torblattelements is then spaced from the guide element. Due to the configuration of the receptacle and the pivot lever, the lower edge of the door leaf with respect to the guide member can be raised only upwards. Lowering is not possible. If the door leaf is moved back from the open position to the closed position, the lower edge of the lower door leaf element is returned from the pivot position to the guide position by pivoting the pivot lever relative to the receptacle. The lower edge of the lower Torblattelements can then be returned along the predetermined path in the closed position.

In a further embodiment of the invention, the first and / or second biasing means may cooperatively urge the separately elevatable edge of the door leaf element into the predetermined path upon movement into the closed position and / or in the closed position urge it into a fully occlusive wall opening position , If the door leaf element having the separate liftable edge is urged into the predetermined path during the movement into the closed position by cooperation of the first pretensioning device and the hinge arrangement, then the door leaf can be moved particularly reliably from the open position into the closed position. Further, by this interaction of the first biasing means with the hinge assembly for Be generated generating the breakaway torque required to initiate the closing movement. Furthermore, a noise development, which disregards the fact that the lower edge of the door leaf is movable approximately orthogonal to the predetermined path can be suppressed. As a result of the interaction of the second pretensioning element with the joint arrangement, in the closed position the lower door leaf element can be forced into a position which completely closes the wall opening. As a result, a particularly secure closure of the closed space with the door leaf can be achieved. Furthermore, noise development can be prevented by a bottom edge of the door leaf element which is moved back and forth, for example, by air pressure orthogonal to the vertical plane. The first biasing means and the second biasing means may be identical or different.

In one embodiment of the invention, the first and / or the second biasing means may comprise a spring element. The first and / or second biasing means may comprise a torsion spring. The lower edge of the lower Torblattelements can then be urged by a spring force in the movement in the closed position in the predetermined path. In the closed position, the lower edge of the door leaf can be urged by the spring force into a position completely closing the wall opening. The torsion spring can be arranged on the shaft of the joint arrangement. The torsion spring may have three legs. The first and third legs may be formed at the opposite ends of the cylindrically shaped torsion spring. The second leg may be formed approximately midway between the first and second legs. The first and the third leg can rest on the pivot lever. The legs can rest against the pivot lever base. The second leg may rest against the receptacle. In this case, the second leg rest against the receiving base. The second leg may be U-shaped. By such an arrangement, the lower edge of the lower door leaf element can be pushed particularly reliable in the transition from the open position to the closed position in the predetermined path and be urged in the closed position in a wall opening completely occlusive position.

In a further embodiment of the invention, a pulling means lifting the door leaf from the closed position into the open position can be connected at one end to the lower edge of the door leaf and coupled at its other end to a counterbalancing device, and the traction means can counteract the first pretensioning device. The traction means may be, for example, a chain or a rope. The traction means can be guided in the closed position of the door leaf from the lower edge of the door leaf via a deflecting element in the vertical direction upwards, where it then further extends approximately in a horizontal direction up to the weight compensation device. The deflecting element may be a chain sprocket and the traction means may be formed as a chain in a first region facing the lower edge of the door leaf. In a second area, which faces the counterweight unit, the traction means may be formed as a rope. The traction means may be formed of metal.

The weight compensation device is used to facilitate the opening movement by urging the door leaf, at least in the closed position to the open position. The weight balancing device can also prevent an uncontrolled closing movement, which takes into account relevant safety regulations. The weight compensation device may comprise a mechanical spring, for example a tension spring or a torsion spring, which acts on the door leaf via the traction means. The weight balancing device is usually tensioned during the closing movement of the door leaf under the action of gravity with the help of the weight of the door leaf. With the spring tension thus generated, the opening movement is supported.

The following describes the movement of the door leaf of a sectional door from the closed position to the open position, wherein the door leaf is lifted by the traction means. The traction means engages the lower edge of the door leaf in order not to excessively burden the articulated connections of the door leaf elements in the course of the opening movement. Rather, it is possible by this arrangement that the individual door members are supported in the opening and closing movement together and are held in total by the attached to the lower edge of the door leaf traction means. The traction means is guided over deflection rollers, that during the entire opening movement of the door leaf, a force acts on the lower edge of the lower Torblattelements, which is directed approximately parallel to the direction of gravity upwards. In the closed position of the door leaf, the lower edge of the lower Torblattelements is urged by an interaction of the hinge assembly and the second biasing member (which may be identical to the first biasing means) in a wall opening completely closing position. The lower edge of the lower door leaf element is arranged adjacent to the guide element arranged on this door leaf element. The guide element may be formed, for example, as a roller. The guide element is arranged in the guide rail assembly and is guided by this. Now the door leaf element is lifted by the traction means upwards. The arranged at the lower edge of the lower Torblattelements guide element then moves due to the positive guidance by the vertical guide rail segment in approximately vertical upward. Due to the interaction of the first biasing element, for example a torsion spring, with the hinge assembly, the lower edge of the lower door leaf element also follows the path of the guide element. The lower edge of the lower door leaf element and the guide element follow together as long as this vertical path until the guide element enters the arcuate guide rail segment. Due to the positive guidance through the arcuate guide rail segment, the guide element continues to follow the arcuate path of the guide rail arrangement. On the lower edge of the lower door leaf element, however, further affects the tensile force of the traction device approximately parallel to the direction of gravity upwards. Since the hinge arrangement allows pivoting of the lower edge of the lower door leaf element with respect to the guide element upwards, the lower edge of the lower door leaf element is consequently lifted upwards. The lower edge of the lower Torblattelements is then spaced from the guide member in the vertical direction. The clear wall opening is thereby further released. The upper door leaf element and the intermediate elements are arranged in this state in a predetermined by the overhead guide rail segment overhead position.

This opening movement can take place under the assistance of the prestressed weight compensation device. The traction means can counteract the first biasing device when lifting the door leaf, possibly supported by the weight balancing device. The biasing means can be biased by the tensile force of the traction means. This biasing force can contribute to the generation of the breakaway element necessary for initiating the closing movement, whereby the transition of the door leaf from the opening to the closed position is enabled and / or supported.

In addition to the overhead guide rail segment, a second overhead guide rail segment may be disposed above the first overhead guide rail segment. This second overhead guide rail segment can accommodate at least the upper edge of the upper door leaf element. As a result, the lintel height can be further reduced. While in the open position of the door leaf, at least the intermediate elements lie approximately in a plane, the lower door leaf element is tilted relative to this plane. The lower door leaf element encloses an acute angle β with the plane of the intermediate elements. At a conventional sectional door without separately liftable edge, the lower door leaf element lies in a plane which is spanned by the upper edge of the lower Torblattelements and arranged in the arcuate guide rail segment guide element. In a sectional door according to the invention with a separately liftable edge, the lower edge of the door leaf is moved upwards relative to the guide element. As a result, the acute angle β, which includes the lower door leaf element with the plane of the intermediate elements is reduced. The clear wall opening is thus further released.

A joint arrangement according to the invention for a gate can enable a change in the distance between at least one guide element arranged on this door leaf element and the door leaf element. For this purpose, the joint arrangement connect the separately liftable Torblattelement and the guide element together. Possible embodiments of the joint arrangement have been explained above. The hinge assembly may be configured such that it cooperates with the first and / or second biasing means during assembly at a gate to urge the separately raisable edge of the door leaf element in the movement in the closing movement in the predetermined path and / or in the closed position in a to push the wall opening completely occlusive position.

In the following description, the invention will be described by way of example with reference to the drawings. In the drawing shows

1 is a perspective view of a section of a sectional door in the open position,

Fig. 2 is a perspective view of a section of a sectional door shortly before reaching the closed position.

Fig. 1 shows a detail of a perspective view of a sectional door 1 in the open position. The door leaf 2 of the sectional door 1 has been transferred by a chain 80 which is fixed to the lower edge 14 of the door leaf 2, from the closed position to the open position. The chain 80 is coupled via a deflection roller 90 with a chain sprocket 92 to a drive device, not shown. The door leaf 2 has a plurality of door leaf elements 10, 12. In the figure, only the lower door leaf element 12 is visible. The door leaf elements 10, 12 are tilted against each other along an approximately parallel to a horizontal tilt axis. In the Schiießstellung (see Fig. 2), the door leaf elements 10, 12 are one above the other arranged. The door leaf 2 is then located approximately in the vertical plane. The door leaf element, which is arranged in the closed position near the bottom, is referred to as the lower door leaf element 12. This door leaf element 12 is the trailing Torblattelement in the transition from the closed position to the open position. The leading in the transition from the closed position to the open position door leaf element is referred to as the upper door leaf element. Between the upper door leaf element and the lower door leaf element further Torblattelemente can be arranged. These door leaf elements are referred to as intermediate elements.

The guide of the door leaf 2 from the open position to the closed position and vice versa along a predetermined path is effected by the interaction of a guide rail arrangement 20 and guide elements, which are formed in Figure 1 in the form of rollers 16.

The guide rail assembly 20 has two guide rails 22 which are disposed on opposite side walls of the wall opening 100. In Figure 1, only one of the two guide rails can be seen. The guide rail 22 has a vertical guide rail segment 26 (not visible in FIG. 1), a guide rail segment extending over the head (not visible in FIG. 1) and an arcuate guide rail segment 22 connecting the vertical guide rail segment 26 and the horizontal guide rail segment. The guide rail arrangement 20 depicted in FIG. 1 additionally has a second head rail segment 24 extending over the head for receiving the guide element arranged on the upper edge of the upper door leaf element. This second overhead guide rail segment 24 is arranged in the direction of gravity S above the overhead guide rail segment. In the open position, the intermediate elements are arranged in the predetermined by the overhead Führungsschjenensegmente level. The upper edge of the lower door leaf element 2 is arranged in the open position also in the plane spanned by the intermediate elements plane. In the open position, the rollers 16 arranged on the lower edge 14 of the lower door leaf element 12 are arranged in the arcuate guide rail segment 22. The rollers 16 are not rigidly connected via a hinge assembly 40 (see Figure 2) opposite the lower door leaf element 12 pivotally connected to the lower door leaf element 12.

The hinge assembly 40 has a receptacle 42 and a pivot lever 60. The pivot lever 60 is pivotable on a first end side 64a with the receptacle 42nd connected. At one of the first end side 64a opposite second end side 64b of the pivot lever 60 is connected to the roller 16. The connection of the roller 16 with the pivot lever 60 is effected in that the roller axle 18 is received in a tubular receptacle 56 of the pivot lever 60. Further details on the hinge assembly 40 will be set forth later with reference to FIG.

Fig. 1 shows the hinge assembly 40 in the pivot position. The separately raised edge 14 of the lower Torblattelements 12 is raised relative to the roller 16 upwards. The lifting is done by the tensile force of attached to the liftable edge 14 of the lower Torblattelements 12 chain 80. The liftable rim 14 is disposed above the arcuate guide rail portion 22. The clear wall opening 100 is further released compared to conventional sectional doors, in which the rollers 16 are not pivotally connected to the door leaf element 14. In addition, the separately selectable edge has a higher potential energy compared to a door leaf in which the lower edge is not pivotally connected to the rollers. This is converted into kinetic energy during the closing movement and contributes to the generation of the breakaway torque. The lifting of the lower edge 14 of the lower Torblattelements 12 is carried out against the restoring force of the biasing means 30 described later. The pretensioner 30 is thus in a prestressed state. If the door leaf 2 is transferred from the open position shown in FIG. 1 into the closed position shown in FIG. 2, then the restoring force of the pretensioning device 30 causes the lower edge 14 of the lower door leaf element 12 to be urged onto the roller 16. As a result, a further contribution of the breakaway torque necessary for initiating the closing movement takes place. Furthermore, the lower edge of the lower door leaf element 12 can be guided reliably in the path predetermined by the guide rail arrangement 20. The biasing means 30 thus corresponds to the first biasing means.

Fig. 2 is a perspective view of a section of the sectional door 1 shortly before reaching the closed position. The figure shows a guide rail 22 of the guide rail assembly 20. In the cutout, only the vertical guide rail segment 26 is shown. This is attached to a Zargenholm 28.

2 further shows the lower door leaf element 12 with the separate liftable edge 14. The roller 16 is fastened to the separate liftable edge 14 of the lower door leaf element 12. The roller 16 is over the hinge assembly 40 relative to the lower Torblattelement 14 pivotally connected to this. The chain 80 for raising and lowering the door leaf 2 is fixed to the lower edge 14 of the lower door leaf element 12.

The joint arrangement 40 of the gate 1 according to the invention is described below. The hinge assembly 40 includes a receptacle 42 and a pivot lever 60. The pivot lever 60 is connected to the receptacle 42 pivotally connected thereto. The receptacle 42 has a receiving base 44, a first receiving side wall 46a and a second receiving side wall 46b. The receptacle 42 is connected via the receiving base 44 fixed to the lower door leaf element 12. The receptacle 42 is connected in the region of the liftable edge 14 of the lower Torblattelements 12 with this. For attachment of the receptacle 42 44 mounting holes 48 and slots 50 are formed in the receiving base. In Fig. 2, the receptacle 42 is connected by a guided through the slot 50 screw 52 with the door leaf element 12. The receiving base 44 extends approximately parallel to the lower Torblattelement 12. The receiving base 44 is formed approximately rectangular in shape. But it can also have any other shape. The first receiving side wall 46a and the second receiving side wall 46b are arranged in a lower region of the receptacle 42 in the closed position. The first and second take-up side walls 46a, 46b extend from the take-up base 44 approximately perpendicular to the take-up base 44 and extend approximately in the direction of gravity S. The first take-up side wall 46a is disposed on a first side edge of the take-up base 44. The second receiving side wall 46b is disposed on a second side edge of the receiving base 44, so that the second receiving side wall 46b is disposed opposite to the first receiving side wall 46a. In the first receiving side wall 46a is a first opening 47a, and in the second receiving side wall 46b, a second opening 47b is formed. A shaft 68 extending between the first receiving side wall 46a and the second receiving side wall 46b is received by the first opening 47a and the second opening 47b and fixed in the receptacle 42. The shaft 68 serves to couple the pivot lever 60 to the receptacle 42. The pivot lever 60 has a pivot lever base 62, a first pivot lever side wall 66a, and a second pivot lever side wall 66b. In the guide position shown in Fig. 2, the pivot lever base 62 is arranged approximately parallel to the receiving base 44. The pivot lever base 62 thus extends approximately parallel to the lower door leaf element 12. The pivot lever base 62 is approximately rectangular in shape and has a dimension that allows the pivot lever base 62 is completely absorbed by the receptacle 42. From the pivot lever base 62, a first pivot lever side wall 66a and a second pivot lever side wall 66b extend such that the first pivot lever side wall 66a of the first pivot lever side wall 66a extends second pivot lever side wall 66b opposite. Also, the first pivot lever side wall 66 a and the second pivot lever side wall 66 b are completely received by the receptacle 42. The shaft 68 is fixedly connected to the first pivot lever side wall 66a and the second pivot lever side wall 66b. The shaft 68 is disposed on a first end side 64a of the pivot lever. By this construction, the pivot lever 60 is pivotable relative to the receptacle 42 in a direction away from the plane of the lower Torblattelements. On a first end face 64a opposite the second end face 64b of the pivoting lever 60, a tubular receptacle 69 for receiving the caster axle 18 is formed. Thus, the roller 16 is connected via the roller axle 18 fixed to the pivot lever 60. The pivot lever 60 is pivotable relative to the receptacle 42 fixedly connected to the lower door leaf element 12. Thus, the lower edge 14 of the lower Torblattelements 12 relative to the guide roller 16 is pivotable.

The illustrated in Fig. 2 joint assembly 40 further includes the biasing means 30. This biasing device 30 urges, as shown in Fig. 2, in the closed position, the door leaf in a wall opening 100 completely closing the closed position. The biasing device 30 thus also corresponds to the second biasing device. The biasing device 30 has a torsion spring 32. This torsion spring 32 has a first leg 34, a second leg 36 and a third leg 38 (not shown). The first and the third leg 34, 38 are respectively formed on the first and second pivot lever side wall 66b, c facing end sides of the torsion spring. The torsion spring 32 is disposed on the shaft 68 of the pivot lever 60. The first leg 34 (and also the third leg 38, not shown) bears against the pivot lever base 62. The second leg 36 is formed approximately in the center of the torsion spring 32. The second leg 36 is U-shaped. The U-shaped portion of the second leg 36 abuts against the receiving base 44 of the hinge assembly 40. To transfer the hinge assembly 40 from the guide position shown in Fig. 2 in the illustrated in Fig. 1 pivoting position of the pivot lever 60 and the receptacle 42 against the restoring force generated by the torsion spring 32 are pivoted against each other. By this restoring force, the lower edge 14 of the lower door leaf element 12 can be urged in the closed position shown in Fig. 2 in a wall opening 100 completely occlusive position. Further, as mentioned above, by the biasing means 30, the lower door leaf member 12 is urged in a transition from the open position shown in Fig. 1 in the closed position shown in FIG. 2 in the predetermined by the guide rail assembly 20 web. Another function of the pretensioner 30 is that it can generate the breakaway torque necessary to initiate the closing movement. If that Door leaf 2 is raised by means of the chain 80 upwards, so the torsion spring 32 is biased during pivoting of the pivot lever 60. If the tension exerted by the chain 80 on the lower edge of the door leaf 2 is reduced, a force is exerted on the lower edge 14 of the lower door leaf element 12 due to the spring force of the torsion spring 32 and can initiate the closing movement of the sectional door.
