Description

[0001] The invention relates to an assembly for assembling gates, a gate made from such an assembly and a use of such an assembly for assembling gates.

[0002] A gate usually comprises a gate leaf that can be moved along a path defined by a guide rail arrangement between a closed position and an open position to close a building opening in a building wall.

[0003] In some embodiments, the guide rail arrangement comprises two guide rails arranged in the region of the lateral edges of the door leaf running parallel to the predetermined path, each of which has a first section running approximately parallel to a lateral edge of the door leaf in the closed position and a second section running substantially straight approximately parallel to a lateral edge of the door leaf in the open position.

[0004] In some embodiments, the door leaf is formed from a plurality of door members arranged one behind the other in the direction of door leaf movement and preferably connected to one another in an articulated manner with respect to hinge axes running perpendicular to the predetermined path, wherein the door leaf is arranged in a vertical plane in the closed position and is preferably arranged overhead in a horizontal plane in the open position.

[0005] Motorized drive systems are typically used to move the door leaf between the open and closed positions. The opening movement, which requires the door leaf to move upwards against the force of gravity, is typically assisted by a counterbalance device.

[0006] Such a counterweight device can be designed in various ways. In some embodiments, a counterweight device can comprise a counterweight located near a lateral edge of the building opening. This counterweight is connected to the door leaf via a coupling device, such as a wire rope running over pulleys. This counterweight is raised during the closing movement of the door leaf, so that part of the kinetic energy or potential energy of the door leaf is converted into potential energy of the counterweight. The counterweight then provides potential energy to support the door leaf movement during the opening movement.

[0007] Furthermore, such a weight compensation device can comprise at least one tension spring arrangement in the region of a lateral edge of the building opening, wherein the tension spring arrangement can be tensioned by stretching along at least one spring axis during the closing movement of the door leaf from the open position to the closed position, thus absorbing kinetic energy or potential energy of the door leaf as spring energy. This spring energy is then available to support the door leaf movement during an opening movement.

[0008] The designs of the weight compensation device with a counterweight or with a spring arrangement allow for greater variability with regard to the requirements of the installation conditions.

[0009] In further embodiments, such as those known from WO 01 / 94731 A1 and US 6401793 B1, the weight compensation device comprises at least one torsion spring in which a strand-shaped spring element spirals around a torsion axis. Such a torsion spring can be tensioned by rotating one end of the strand-shaped spring element about the torsion axis, while the other end is held fixed to the building. Such a rotation can be brought about during a closing movement of the door leaf if a traction means, which is coupled to the leading door member during the closing movement, is unwound from a storage device connected in a rotationally fixed manner to the rotatable end of the strand-shaped spring element, while rotating the storage device and utilizing gravity.The traction device can be a wire rope, while the storage device can be a rope drum that is non-rotatably connected to the rotating end of the torsion spring.

[0010] The spring energy released during the closing movement is converted into and absorbed by the torsion spring, which is then available to support the opening movement. This typically involves an electric motor drive coupled to the storage device, such as the cable drum, which sets it in rotation during the opening movement. During this process, the tension device is rewound, assisted by the spring energy absorbed by the torsion spring.

[0011] It has proven particularly expedient for the weight compensation device to preferably comprise two torsion springs, each of which is fastened to a spring shaft. The spring shafts with the torsion springs attached thereto are coaxially connected to one another by a shaft coupling, such that the spring shafts form a common spring shaft with a common spring shaft axis. The common spring shaft is fastened at one end to the building wall by means of a bracket in an area above a lateral edge of the building opening, and at the other end to the building wall by means of a further bracket in an area above an opposite lateral edge of the building opening. In addition, the common spring shaft is fastened to a lintel of the building wall by means of a shaft holder arrangement in an area approximately centrally between the opposite lateral edges of the building opening.In this arrangement, the common spring shaft is mounted in the bracket, the additional bracket, and the shaft support assembly in such a way that the common spring shaft can rotate around the approximately horizontally aligned common spring shaft axis. Furthermore, the torsion springs are aligned approximately symmetrically to each other and to the building opening, thereby efficiently transferring the spring energy stored in the torsion springs to the door leaf.

[0012] Typically, the width of a counterbalance device exceeds the width of the building opening, which, depending on the design, can even be 4 m, 5 m, or more. For example, if a counterbalance device only comprises a torsion spring attached to a spring shaft, this results in increased installation effort and also requires larger containers during delivery, which in particular exceed the volume of conventional containers with a maximum size approximately the size of the door leaf.

[0013] Against this background, weight compensation devices with preferably two torsion springs have proven to be particularly useful, as they can reduce the assembly effort and the effort during delivery of the corresponding containers, but can also ensure a particularly efficient transmission of force from the weight compensation device to a door leaf.

[0014] Manufacturers usually sell assemblies with individual, separate components, which are delivered in containers and assembled on-site at a building with a building opening that needs to be closed.

[0015] During installation, frames are first aligned with the side edges of the building opening on the building wall with a longitudinal axis in a vertical orientation, preferably approximately parallel to the side edges of the building opening, and then attached to the building wall. The first guide rail sections are then attached to the frames approximately vertically, preferably parallel to the side edges of the building opening.

[0016] In a further step, the second guide rail sections are preferably aligned horizontally with a longitudinal axis in the direction of the first section and are mounted overhead on the building, preferably to the ceiling of the room to be closed, by means of a suspension device. A first guide rail section is connected to a second guide rail section, for example, by means of an arcuate section of the guide rail such that, after assembly, the door leaf can be moved along the guide rails from the closed position to the open position in the direction of door leaf movement.

[0017] In a further step, the weight compensation device is attached to the building wall in an area in the direction of gravity above the building opening.

[0018] During assembly, a torsion spring is first attached to a spring shaft, with the spring shaft extending in the direction of the torsion spring axis through a torsion spring bushing of the torsion spring, so that opposite ends of the spring shaft protrude from the torsion spring bushing.

[0019] The spring shaft is aligned with a spring shaft axis approximately parallel to the horizontal and mounted so as to be rotatable about the spring shaft axis relative to the guide rail arrangement. For this purpose, a bracket is provided which is aligned on the building wall in an area on the lateral edge in the direction of gravity above the building opening and is fastened to the building wall. Such a bracket can, for example, be integrated into one of the frames or designed as a separate component. The spring shaft, with the spring shaft axis aligned approximately parallel to the horizontal and with the torsion spring attached to it, is rotatably mounted in the bracket at the end protruding from the torsion spring guide. For example, a bracket attached to the building wall can have a guide opening with a bearing in which the spring shaft is mounted so as to be rotatable about the spring shaft axis.

[0020] The spring shaft is then fastened to the building wall by means of a shaft holder arrangement such that the spring shaft axis is aligned approximately parallel to a horizontal and is mounted so as to be rotatable about the spring shaft axis. For this purpose, the spring shaft arrangement has a shaft holder in which the spring shaft is rotatably mounted. In addition, the shaft holder arrangement has a shaft holder bracket which is attached to a lintel of the building wall in an area preferably approximately centrally between the lateral edge and an opposite lateral edge of a building opening. To fasten the spring shaft, which is rotatably mounted in the shaft holder, to the building wall, the shaft holder is fastened to the shaft holder bracket fastened to the lintel by means of a fastening arrangement.

[0021] A further bracket designed for the rotatable mounting of a further spring shaft, which is for example integrated into a frame and has already been fastened to the building wall, or can for example be designed as a separate component, is or will be attached to the building wall in an area of ​​the building wall in the direction of gravity above the opposite lateral edge of the building opening.

[0022] A further torsion spring can be attached to the further spring shaft, wherein the further spring shaft extends in a torsion spring passage of the further torsion spring, which extends along a torsion axis of the second torsion spring. The further spring shaft is then rotatably mounted at one end in the further bracket, for example in a provided passage opening of the further bracket with a bearing, and is connected at an opposite end by means of a spring shaft coupling to the spring shaft mounted in the shaft holder in such a way that the spring shaft axes of the spring shaft and the further spring shaft are coaxially aligned and the spring shaft and the further spring shaft are jointly rotatably mounted about a common spring shaft axis, which is formed by the coaxially aligned spring shaft axis and the further spring shaft axis.The common spring shaft axis is aligned approximately parallel to the horizontal, preferably parallel to an upper edge of the building opening.

[0023] In a further step, the door sections are assembled to form a door leaf and mounted in the guide rails by means of rollers attached to the door sections via roller holders in such a way that the door leaf can be moved in the direction of movement between the closed position and the open position along the path specified by the guide rails.

[0024] Against this background, the object of the invention is to provide an assembly for a gate which enables simplified assembly of a gate.

[0025] This problem is solved by an assembly having the features of the main claim. The solution is based on the inventors' recognition that attaching the weight compensation device to the lintel above the building opening accounts for a significant portion of the assembly effort, and in particular, attaching the spring shaft to the lintel using the shaft holder assembly approximately centrally between opposing lateral edges of the building opening accounts for a significant portion of the personnel expenditure, sometimes requiring several fitters. The inventors have therefore recognized that simplifying the assembly of the shaft holder assembly can significantly reduce the overall effort required to install the door, and that such a weight compensation device can even be installed by a single person.

[0026] According to the features of the characterizing part of the main claim, the fastening arrangement comprises a receptacle receiving the fastening bolt extending approximately parallel to the spring shaft axis, into which receptacle the fastening bolt can be inserted by a relative movement with respect to the receptacle in a direction extending transversely, in particular approximately perpendicularly, to the spring shaft axis.

[0027] In this respect, during assembly, a shaft holder can be suspended in the shaft holder bracket, which is fastened to the lintel of the building opening in an area approximately centrally between opposite lateral edges, by means of the fastening bolt engaging in the receptacle and extending approximately parallel to the spring shaft axis in a relative movement with respect to the receptacle approximately transverse to the spring shaft axis, in the shaft holder bracket, whereby assembly is made significantly easier and personnel costs can be reduced.

[0028] In some embodiments, the spring shaft can be aligned approximately horizontally with the spring shaft axis, preferably parallel to the upper edge of the building opening. The spring shaft can then be rotatably mounted in the shaft holder, and the shaft holder can be suspended in the shaft holder mount attached to the lintel, in the previously described relative movement with respect to the receptacle, approximately transversely or perpendicularly in the direction of the spring shaft axis.

[0029] In other embodiments, the spring shaft can be rotatably mounted in the shaft holder and then aligned with the spring shaft axis parallel to the horizontal, preferably parallel to the upper edge of the building opening, and suspended in the described relative movement transverse to the approximately horizontally aligned spring shaft axis in the shaft holder bracket attached to the lintel.

[0030] The bolt may, for example, extend along a bolt longitudinal axis which is aligned approximately parallel to the spring shaft axis during assembly.

[0031] In addition, some particularly preferred embodiments are described below.

[0032] In a preferred embodiment, the receptacle is characterized in that the receptacle extends from a receptacle opening at least partially in a direction approximately transverse, in particular approximately perpendicular to the spring shaft axis.

[0033] According to this embodiment, the previously described relative movement of the fastening bolt and the receptacle is enabled in a direction approximately transverse to, in particular approximately perpendicular to, the spring shaft axis. The fastening bolt can be inserted into the receptacle through the receiving opening during the relative movement with respect to the receptacle in a direction approximately transverse to the spring shaft axis.

[0034] In some embodiments, during assembly, the receptacle may extend from the receptacle opening in the direction approximately transverse to the spring shaft axis in the direction of the camber or may extend from the receptacle opening in a direction opposite to the camber.

[0035] In a preferred embodiment, the receptacle and the fastening bolt have contact surfaces which, after assembly, are in contact with each other in such a way that the shaft holder is supported on the shaft holder support in the direction of gravity.

[0036] Such contact surfaces allow the shaft holder bracket and the shaft holder to rest on each other in such a way that the shaft holder bracket and the shaft holder are supported on each other in the direction of gravity.

[0037] In exemplary embodiments, a contact surface of the receptacle can be arranged on a lower edge of the receptacle in the direction of gravity and a contact surface of the fastening bolt can be arranged on a lower edge of the fastening bolt in the direction of gravity, so that the fastening bolt received in the receptacle rests with its contact surface on the contact surface of the receptacle in the direction of gravity.

[0038] In other exemplary embodiments, a contact surface of the receptacle can be arranged on an upper edge of the receptacle in the direction of gravity and a contact surface of the fastening bolt can be arranged on an upper edge of the fastening bolt in the direction of gravity, so that the receptacle receiving the fastening bolt rests with the contact surface of the receptacle in the direction of gravity on the contact surface of the fastening bolt.

[0039] In a preferred embodiment, a contact surface of the receptacle has an inclination relative to a horizontal.

[0040] By designing the holder in this way, the shaft holder can be suspended in the shaft holder bracket during assembly or can be supported on the shaft holder bracket in the direction of gravity, whereby the fastening bolt is prevented from slipping out of the holder.

[0041] In an exemplary embodiment, the contact surface can extend along a longitudinal axis, wherein the longitudinal axis forms an acute angle with a horizontal line directed approximately transversely, preferably approximately perpendicularly, to the spring shaft axis. In particular embodiments, the acute angle can have a positive sign, or in other embodiments, the acute angle can have a negative sign.

[0042] In a preferred embodiment, the shaft holder holder comprises the receptacle.

[0043] According to this preferred embodiment, a fastening bolt extending approximately parallel to the spring shaft axis and fastened to the shaft holder can be inserted during assembly into the receptacle of the shaft holder bracket fastened to the lintel with a movement transverse to the spring shaft axis in the direction of the lintel.

[0044] In this embodiment, the receiving opening of the receptacle can be arranged, for example, on a side of the shaft holder holder facing away from the lintel, wherein the receptacle extends from the receiving opening in the direction of the lintel into the shaft holder holder and preferably has an inclination with respect to a horizontal direction directed approximately transversely, preferably perpendicularly, to the lintel.

[0045] In other embodiments, however, it is also possible for the shaft holder to comprise the receptacle and for a fastening bolt fastened to the shaft holder holder and extending approximately parallel to the spring shaft axis to be inserted into the receptacle by a movement of the shaft holder transversely to the spring shaft axis in the direction of the shaft holder holder fastened to the lintel.

[0046] In a preferred embodiment, the shaft holder holder comprises a further holder of the same shape, arranged symmetrically to the holder, preferably at right angles to the holder, for fastening the shaft holder to the building wall.

[0047] According to this embodiment, the attachment of the shaft holder bracket to the lintel is facilitated during assembly because, due to its symmetry, the shaft holder bracket can be attached to the lintel in various ways, allowing insertion of the fastening bolt in the described relative movement with respect to the receptacle. Thus, it is possible for a single person to attach the shaft holder bracket to the lintel in a single step and to insert the shaft holder into the receptacle of the shaft holder bracket attached to the lintel using the fastening bolt attached to the shaft holder.

[0048] In a further preferred embodiment, the shaft holder has a lateral support surface which comes into contact with the lintel after assembly, so that the shaft holder is at least partially supported on the lintel by the lateral support surface after assembly.

[0049] According to this embodiment, the weight force acting on the shaft holder bracket in the direction of gravity is reduced. For example, after assembly, the weight of the shaft holder and the components attached to it can be partially supported via the fastening arrangement on the shaft holder bracket attached to the lintel and partially supported directly on the lintel via the lateral support surface. The additional support of the shaft holder on the lintel reduces the weight force acting on the shaft holder bracket in the direction of gravity.

[0050] In a preferred embodiment, the shaft holder has a shaft holder opening for receiving and fastening the fastening bolt extending approximately parallel to the spring shaft axis.

[0051] According to this embodiment, during assembly, the fastening bolt extending approximately parallel to the spring shaft axis can be guided through the shaft holder opening with a movement parallel to the spring shaft axis and then inserted into the receptacle with an end protruding from the shaft holder approximately parallel to the spring shaft axis with a movement approximately transverse, in particular perpendicular, to the spring shaft axis. This can facilitate the attachment of the shaft holder to the shaft holder mount during assembly.

[0052] In a preferred embodiment, the receiving opening is arranged after assembly on a side of the shaft holder bracket facing away from the lintel and towards the interior of the building.

[0053] This arrangement allows the fastening bolt to be inserted into the socket from the inside of the building during installation with a movement in the direction of the lintel.

[0054] In a preferred embodiment, the spring shaft axis is aligned approximately horizontally.

[0055] This arrangement allows the spring shaft and thus the torsion spring to be coupled to the door leaf in a particularly advantageous manner, so that spring energy introduced into and absorbed by the torsion spring can be transferred particularly efficiently to the door leaf to support the opening movement of the door leaf.

[0056] In a preferred embodiment, the fastening bolt comprises a screw. A screw as a fastening means has proven particularly advantageous for assembly. For example, a screw can be easily passed through the correspondingly provided shaft holder opening in a movement approximately parallel to the spring shaft axis. Advantageously, after the screw is received in the receptacle, the shaft holder bracket and the shaft holder can be fastened together by tightening a nut adapted to the screw.

[0057] Furthermore, the object is achieved by a door produced from an assembly according to the invention, with a door leaf movable along a path predetermined by a guide rail arrangement between a closed position and an open position and with a weight compensation arrangement coupled to the door leaf via a coupling arrangement and designed to support the door leaf movement from the closed position to the open position, which comprises the following components: a bracket which is fastened to a building wall in an area in the direction of gravity above a lateral edge of a building opening;a shaft holder arrangement with a shaft holder, which is attached by means of a fastening arrangement comprising a fastening bolt to a shaft holder bracket fastened to a lintel of the building wall in a region preferably approximately centrally between the lateral edge and a lateral edge of the building opening opposite the lateral edge; a torsion spring tensionable about a torsion axis and a spring shaft received in a torsion spring passage of the torsion spring directed in the direction of the torsion axis, wherein the spring shaft is rotatably mounted with one end in the console and with a region opposite the one end in the shaft holder about the spring shaft axis.

[0058] Such a gate is characterized in that the fastening arrangement comprises a receptacle which can accommodate the fastening bolt extending approximately parallel to the spring shaft axis in a relative movement with respect to the receptacle in a direction extending approximately transversely to the spring shaft axis.

[0059] As previously described, a fastening arrangement designed in this way makes a door manufactured from a single assembly particularly easy to install, thereby reducing installation costs. In particular, the counterweight device can be installed overhead above the building opening during installation, preferably by just one person. Furthermore, handling during installation is simplified. In particular, handling is more ergonomic, as one installer's hand remains free and can be placed down during installation.

[0060] In a preferred embodiment, the fastening arrangement comprises a further bracket which is fastened in a region of the building wall on the opposite lateral edge of the building opening in the direction of gravity above the wall opening; and comprises a further spring shaft which is received in a torsion spring passage of a further torsion spring directed in the direction of a torsion axis, wherein the further spring shaft is fastened at one end to the spring shaft by means of a spring shaft coupling and is rotatably mounted at an opposite end on the further bracket about the spring shaft axis.

[0061] As explained above, the weight compensation device can be formed from several components and, in particular, can include an additional torsion spring to support the door leaf movement. A fastening arrangement according to the invention is particularly advantageous in this context, since a weight compensation device with several torsion springs can be installed overhead in one step, preferably by a single person.

[0062] In a further embodiment, the spring shaft is coupled to the door leaf at the end mounted in the bracket via a coupling device and the further spring shaft is coupled to the door leaf at the end mounted in the further bracket via the coupling device.

[0063] Such a coupling device can, for example, comprise the traction means described above and preferably the storage device. Such a coupling device couples the torsion springs to the door leaf via the spring shafts attached to them, thus supporting the door leaf movement.

[0064] In further embodiments, a gate can be assembled particularly easily using an assembly according to the invention.

[0065] Accordingly, the object mentioned at the outset is achieved by using an assembly according to the invention for mounting a gate, comprising the steps of: fastening a bracket to a building wall in an area above a lateral edge of a building opening; receiving a spring shaft in a torsion spring passage directed along a torsion axis, for a torsion spring that can be tensioned about the torsion axis; supporting the spring shaft with one end in the bracket so that the spring shaft can be rotated in the bracket about the spring shaft axis; fastening a shaft holder mount in an area, preferably approximately centrally between the lateral edge and a lateral edge of the building opening opposite the lateral edge, to a lintel of the building wall; supporting the spring shaft in a shaft holder so that the spring shaft can be rotated in the shaft holder about the spring shaft axis.Fastening the shaft holder to the shaft holder bracket by means of a fastening arrangement comprising a fastening bolt;

[0066] Such a use is characterized in particular in that during the fastening of the shaft holder to the shaft holder support, the fastening bolt extending approximately parallel to the spring shaft axis is received in the receptacle of the fastening arrangement in a relative movement with respect to a receptacle of the fastening arrangement in a direction extending transversely to the spring shaft axis.

[0067] This means that a gate can be installed with very little personnel expenditure, preferably by just one person.

[0068] In a further embodiment, the use further comprises the steps of: fastening a further bracket to the building wall in an area on the opposite lateral edge of the building opening in the direction of gravity above the wall opening; receiving a further spring shaft in a torsion spring passage directed along a torsion axis of a further torsion spring tensionable about the torsion axis; supporting the further spring shaft with one end in the further bracket such that the further spring shaft is rotatable in the further bracket about the spring shaft axis; fastening an opposite end of the further spring shaft to the spring shaft by means of a shaft holder coupling.

[0069] According to this embodiment, a further torsion spring of the weight compensation device is attached to the building wall for particularly efficient transmission of the spring energy stored in the further torsion spring to the door leaf.

[0070] In the following, further properties, features and advantages of the invention will become clear by describing preferred embodiments of the invention with reference to the accompanying exemplary drawings, in which: Fig. 1 shows an example of how a weight compensation device is attached to a building wall. Fig. 2 shows an example of a design of a shaft holder arrangement in a loose state. Fig. 3 shows an example of a design of a shaft holder arrangement in a fastened state.

[0071] Reference symbols in the figures refer to the same elements.

[0072] Figure 1 shows, by way of example, a view of a building opening 5 from the interior of the building. The building opening 5 is located in a building wall 4 and is delimited by opposite lateral edges 6 and an upper edge 11 relative to the building wall 4.

[0073] In the illustration, a weight compensation arrangement is provided on the building wall 4, arranged above the building opening 5 in the direction of gravity. The weight compensation device comprises a bracket 2, which is fastened to the building wall 4 in an area above a lateral edge 6 of the building opening 5 in the direction of gravity. A spring shaft 1 extending along a spring shaft axis F is rotatably mounted at one end in the bracket 2. The spring shaft axis F is aligned approximately horizontally, in particular approximately parallel to the upper edge 11 of the building opening 5. For the rotatable mounting of the spring shaft, the bracket 2 can have a feed-through opening with a bearing 3.

[0074] The weight compensation assembly further comprises a torsion spring 17 that can be tensioned around a torsion axis and in which the spring shaft 1 is arranged in a torsion spring passage extending in the direction of the torsion axis. After assembly, the torsion axis is aligned coaxially with the spring shaft axis F, in particular approximately parallel to the upper edge 11. The torsion spring 17 can also be coupled to a door leaf via a coupling device (not shown) to assist a door leaf movement.

[0075] In an area approximately centrally between the lateral edge 6 and an opposite lateral edge 6 of the building opening 5, a shaft holder assembly for rotatably supporting the spring shaft 1 is provided on the lintel 7. For this purpose, the shaft holder assembly comprises a shaft holder mount 8, which is fastened to the lintel 7 in an area approximately centrally between the opposing lateral edges 6 of the building opening 5, in the direction of gravity above the building opening 5.

[0076] The shaft holder assembly further comprises a shaft holder 9, which is fastened to the shaft holder bracket 8 by means of a fastening arrangement 12. The spring shaft 1 is rotatably mounted in the shaft holder 9 at a region opposite the end mounted in the bracket 2 in the direction of the spring shaft axis F. For rotatably supporting the spring shaft 1, a through-opening with a bearing 10 can be provided in the shaft holder 9, in which the spring shaft 1 is rotatably mounted about the spring shaft axis F.

[0077] The weight compensation device further comprises a further bracket 19, which is fastened to the building wall 4 in an area in the direction of gravity above the opposite lateral edge 6. In the further bracket 19, a further spring shaft 18 with a further spring shaft axis aligned coaxially to the spring shaft axis F is rotatably mounted at one end. The further spring shaft 18 is fastened to the spring shaft 1 by means of a shaft coupling 22 with an end opposite the end mounted in the further bracket 19. In this respect, the spring shaft 1 and the further spring shaft 18 form a common spring shaft and have a common spring shaft axis about which the spring shaft 1 and the further spring shaft 18 can rotate. For the rotatable mounting of the further spring shaft 18, the further bracket 19 preferably has a through-opening with a bearing 20.

[0078] In addition, the weight compensation device has a further torsion spring 21 which can be tensioned about a torsion axis and has a torsion spring passage extending along the torsion axis of the further torsion spring 21, in which the further spring shaft 18 is arranged.

[0079] Figure 2shows a detailed view of a possible embodiment of a shaft holder arrangement. The shaft holder arrangement comprises a shaft holder holder 8 for fastening to the building wall 4. For this purpose, the shaft holder holder 8 has a fastening device 24 on a first side for fastening the shaft holder holder 8 to the lintel 7 of the building wall 4. In the shaft holder holder 8, a fastening arrangement 12 is provided with at least one receptacle 13 for receiving the fastening bolt 15, preferably on a second side of the shaft holder holder 8 opposite the first side. The receptacle 13 has a receiving opening 14 which, after assembly, is arranged on a side of the shaft holder holder 8 facing away from the lintel, or on the second side, wherein the receptacle 13 extends from the receiving opening 14 at least partially in the direction of the lintel 7 or in the direction of the first side.

[0080] Furthermore, the shaft holder arrangement comprises a shaft holder 9 for the rotatable mounting of the spring shaft 1 with a spring shaft axis F oriented approximately horizontally, in particular parallel to the upper edge 11. For this purpose, the shaft holder 9 comprises a through-opening with a bearing 10, in which the spring shaft 1 is rotatably mounted about the spring shaft axis F with the spring shaft axis F oriented approximately parallel to the upper edge 11. In addition, at least one shaft holder opening 16 is provided in the shaft holder 9, through which at least one fastening bolt 15 can be passed during assembly, extending along a fastening bolt longitudinal axis oriented approximately parallel to the spring shaft axis F, in particular parallel to the upper edge 11 of the building opening 5.

[0081] The fastening arrangement 12 is designed such that, during assembly, the shaft holder 9 can be inserted into the receptacle 13 of the shaft holder bracket 8 fastened to the lintel 7, with a movement transversely, preferably approximately perpendicularly, to the spring shaft axis F in the direction of the lintel 7. In this respect, the shaft holder 9 can be inserted into the at least one receptacle 13 of the shaft holder bracket 8 by means of the at least one fastening bolt 15, with the bolt longitudinal axis aligned approximately parallel to the spring shaft axis F, in a movement in the direction of the lintel 7, so that the shaft holder 9 is fastened to the shaft holder bracket 8 in the direction of gravity. In other words, the shaft holder 9 is suspended in the shaft holder bracket 8 by means of the fastening arrangement 12 and supported by it in the direction of gravity.

[0082] To support the bolt, the receptacle 13 may have a contact surface 23, preferably on a lower side in the direction of gravity, on which the fastening bolt 15 received in the receptacle 13 rests at least partially. In order to prevent a fastening bolt 15 received in the receptacle 13 from slipping out of the receptacle 13, the contact surface 23 at the receiving opening 14 enclose an acute angle with a horizontal direction approximately perpendicular to the fall.

[0083] As can also be seen from the illustration, the shaft holder holder 8 has a further holder of the same shape, arranged symmetrically to the holder 13, preferably at right angles, as a fastening device 24 for fastening the shaft holder 8 to the building wall 4. As shown in the following illustration in Fig. 3 As can be seen, the fastening device 24 can also be designed differently.

[0084] Figure 3 shows the shaft holder arrangement in a state in which the shaft holder 9 is fastened to the shaft holder bracket 8 by means of the fastening device 12.
