Description

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.

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 for closing a building opening in a building wall.

In some embodiments, the guide rail arrangement has 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 approximately straight, and a second section running essentially parallel to a lateral edge of the door leaf in the open position.

In some embodiments, the door leaf is formed from a plurality of door members arranged one behind the other in the direction of movement of the door leaf 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.

Motor-driven drive systems are usually used to move the door leaf between the open and closed positions. The opening movement, in which the door leaf must be moved upwards against the force of gravity, is usually supported by a weight compensation device.

Such a weight compensation device can be designed in various ways. In some embodiments, a weight compensation device can comprise a counterweight in the area of a side edge of the building opening, which is connected to the door leaf via a coupling device such as a wire rope running over pulleys and which 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 movement of the door leaf during the opening movement.

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

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.

In further embodiments, 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 around 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 gate leaf if a traction means coupled to the gate member that moves forward during the closing movement is unwound from a storage device that is connected in a rotationally fixed manner to the rotating end of the strand-shaped spring element, while rotating the storage device and utilizing gravity. The traction means can be a wire rope, while the storage device can be a rope drum that is connected in a rotationally fixed manner to the rotating end of the torsion spring.

The spring energy introduced into the torsion spring and absorbed by it by converting potential energy released during the closing movement is available to support the opening movement. An electric motor drive is usually used, which is coupled to the storage means, such as the cable drum, and sets this in a rotary motion during the opening movement, during which the traction means is rewound, supported by the spring energy absorbed in the torsion spring.

It has proven particularly useful that the weight compensation device preferably comprises two torsion springs, each of which is attached to a spring shaft. The spring shafts with the torsion springs attached to them are coaxially connected to one another with a shaft coupling, so that the spring shafts form a common spring shaft with a common spring shaft axis. The common spring shaft is attached 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 attached to a lintel of the building wall by means of a shaft holder arrangement in an area approximately midway between the opposite lateral edges of the building opening. In this arrangement, the common spring shaft is mounted in the bracket, the further bracket and the shaft holder arrangement in such a way that the common spring shaft can rotate about the approximately horizontally aligned common spring shaft axis. Furthermore, the torsion springs are aligned approximately symmetrically to each other and to the building opening, whereby the spring energy stored in the torsion springs is efficiently transferred to the door leaf.

The width of a weight compensation device usually exceeds the width of the building opening, which can even be 4 m, 5 m or more depending on the design. If, for example, a weight compensation device only comprises a torsion spring attached to a spring shaft, this leads to increased assembly work, but also to containers with a larger volume during delivery, which in particular exceed the volume of conventional containers with a maximum size approximately the same as the door leaf dimensions.

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 corresponding containers, but can also ensure a particularly efficient transmission of force from the weight compensation device to a door leaf.

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

During assembly, frames are first aligned in an area of 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 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.

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 attached overhead to the building, preferably to a 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, in such a way that after assembly the door leaf can be moved in the direction of door leaf movement along the guide rails from the closed position to the open position.

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.

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.

The spring shaft is aligned with a spring shaft axis approximately parallel to the horizontal and is mounted so that it can rotate around the spring shaft axis relative to the guide rail arrangement. For this purpose, a bracket is provided which is mounted on the building wall in a Area on the side edge is aligned in the direction of gravity above the building opening and is attached to the building wall. Such a bracket can, for example, be integrated in one of the frames or designed as a separate component. The spring shaft, which is aligned with the spring shaft axis approximately parallel to the horizontal and has 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 rotatably mounted about the spring shaft axis.

The spring shaft is then attached 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 holder which is attached to a lintel of the building wall in an area preferably approximately centrally between the side edge and an opposite side edge of a building opening. To attach the spring shaft, which is rotatably mounted in the shaft holder, to the building wall, the shaft holder is attached to the shaft holder holder attached to the lintel by means of a fastening arrangement.

A further bracket designed for the rotatable mounting of a further spring shaft, which is for example integrated in a frame and has already been attached 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.

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 extending along a torsion axis of the second torsion spring. The further spring shaft is then rotatably mounted with one end in the further bracket, for example in a passage opening provided for this purpose in the further bracket with a bearing, and is connected with 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 aligned coaxially and the spring shaft and the further spring shaft are mounted together so as to be rotatable 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.

In a further step, the gate sections are assembled to form a gate leaf and are mounted in the guide rails by means of rollers attached to the gate sections via roller holders in such a way that the gate 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.

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

This problem is solved by an assembly with the features of the main claim. The solution is based on the inventors' realization that the attachment of the weight compensation device to the lintel above the building opening takes up a significant part of the assembly effort and in particular the attachment of the spring shaft to the lintel using the shaft holder arrangement approximately in the middle between opposite lateral edges of the building opening is responsible for a significant part of the personnel effort, sometimes involving several fitters. In the course of this, the inventors realized that by simplifying the assembly of the shaft holder arrangement, the overall effort for assembling the gate can be significantly reduced and that such a weight compensation device can even be assembled by a single person.

According to the features of the characterizing part of the main claim, the fastening arrangement comprises a receptacle which receives the fastening bolt extending approximately parallel to the spring shaft axis and into which 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.

In this respect, during installation, a shaft holder can be inserted into the shaft holder bracket, which is attached to the lintel of the building opening in an area approximately midway between opposite lateral edges, by means of the shaft holder engaging in the receptacle. The fastening bolt extending approximately parallel to the spring shaft axis can be hung in the shaft holder holder in a relative movement with respect to the receptacle approximately transverse to the spring shaft axis, which significantly simplifies assembly and can reduce personnel costs.

In some embodiments, the spring shaft can be aligned with the spring shaft axis approximately horizontally, 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 vertically in the direction of the spring shaft axis.

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 transversely to the approximately horizontally aligned spring shaft axis in the shaft holder bracket attached to the lintel.

For example, the bolt may extend along a bolt longitudinal axis which is aligned approximately parallel to the spring shaft axis during assembly.

In addition, some particularly preferred embodiments are described below.

In a preferred embodiment, the receptacle is characterized in that the receptacle extends from a receptacle opening at least partially in a direction approximately transversely, in particular approximately perpendicularly to the spring shaft axis.

According to this embodiment, the previously described relative movement of the fastening bolt and the receptacle is made possible in the direction approximately transversely, in particular approximately perpendicularly to the spring shaft axis. In this case, the fastening bolt can be introduced into the receptacle through the receptacle opening in the relative movement with respect to the receptacle in the direction approximately transversely to the spring shaft axis.

In some embodiments, during assembly, the receptacle may extend from the receptacle opening in a 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.

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

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.

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.

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.

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

By designing the holder in this way, the shaft holder can be hung 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.

In an exemplary embodiment, the contact surface can extend along a longitudinal axis, wherein the longitudinal axis forms an acute angle with an approximately transverse, preferably includes horizontals directed approximately perpendicular 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.

In a preferred embodiment, the shaft holder bracket comprises the receptacle.

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.

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.

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 introduced 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.

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

According to this embodiment, the attachment of the shaft holder bracket to the lintel during assembly is made easier by the fact that the shaft holder bracket can be attached to the lintel in different ways due to its symmetry, whereby the fastening bolt can be inserted in the described relative movement with respect to the receptacle. It is thus possible for a single person to attach the shaft holder bracket to the lintel 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.

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.

According to this embodiment, a 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.

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.

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 fastening of the shaft holder to the shaft holder mount during assembly.

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.

This arrangement allows the fastening bolt to be inserted into the holder from the inside of the building during assembly with a movement in the direction of the lintel.

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

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 to the door leaf particularly efficiently to support the opening movement of the door leaf.

In a preferred embodiment, the fastening bolt comprises a screw.

A screw as a fastening means has proven to be particularly advantageous for assembly. For example, a screw can be easily guided through the correspondingly provided shaft holder opening in a movement approximately parallel to the spring shaft axis and, after the screw has been inserted into the holder, the shaft holder bracket and the shaft holder can advantageously be fastened to one another by tightening a nut adapted to the screw.

The object is further achieved by a gate made from an assembly according to the invention, with a gate leaf that can be moved 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 gate leaf via a coupling arrangement and designed to support the gate leaf movement from the closed position to the open position, which comprises the following components: a bracket that 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 that is attached by means of a fastening arrangement comprising a fastening bolt to a shaft holder bracket that is fastened to a lintel of the building wall in an area preferably approximately centrally between the lateral edge and a lateral edge of the building opening opposite the lateral edge; a torsion spring that can be tensioned about a torsion axis and a spring shaft that is accommodated in a torsion spring passage of the torsion spring that is directed in the direction of the torsion axis, wherein the spring shaft is rotatably mounted about the spring shaft axis with one end in the bracket and with a region opposite the one end in the shaft holder;
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 running approximately transversely to the spring shaft axis.

As previously described, a fastening arrangement designed in this way makes it particularly easy to assemble a door made from a single component, which can reduce assembly costs. In particular, the weight compensation device can be installed overhead above the building opening during assembly, preferably by just one person. In addition, handling during assembly is simplified. In particular, handling is more ergonomic, as one of the fitter's hands remains free and can be set down during assembly.

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 to the spring shaft at one end by means of a spring shaft coupling and is mounted at an opposite end on the further bracket so as to be rotatable about the spring shaft axis.

As explained at the beginning, the weight compensation device can be formed from several components and in particular can comprise a further torsion spring to support the movement of the door leaf. A fastening arrangement according to the invention is particularly advantageous in this context, since a weight compensation device with several torsion springs can be mounted overhead in one step, preferably by a single person.

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.

Such a coupling device can, for example, comprise the traction means described above and preferably the storage device. By means of such a coupling device, the torsion springs are coupled to the door leaf via the spring shafts attached thereto in order to support the movement of the door leaf.

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

Accordingly, the object mentioned at the outset is achieved by using an assembly according to the invention for assembling 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 of 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 in the bracket can be rotated about the spring shaft axis; fastening a shaft holder holder 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 in the shaft holder can be rotated about the spring shaft axis; fastening the shaft holder to the shaft holder holder by means of a fastening arrangement comprising a fastening bolt.

Such a use is characterized in particular by the fact that during the fastening of the shaft holder to the shaft holder holder, 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 running transversely to the spring shaft axis.

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

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 that can be tensioned about the torsion axis; supporting the further spring shaft with one end in the further bracket so that the further spring shaft can rotate about the spring shaft axis in the further bracket; fastening an opposite end of the further spring shaft to the spring shaft by means of a shaft holder coupling.

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.

The weight compensation device also has a further bracket 19, which is attached 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 is rotatably mounted at one end with a further spring shaft axis aligned coaxially to the spring shaft axis F. The further spring shaft 18 is connected to a The spring shaft 1 is fastened to the spring shaft 1 by means of a shaft coupling 22 at the 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.

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.

Figure 2 shows a detailed view of a possible design 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 with at least one receptacle 13 for receiving the fastening bolt 15 is provided, 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.

Furthermore, the shaft holder arrangement comprises a shaft holder 9 for rotatably supporting the spring shaft 1 with a spring shaft axis F aligned 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 supported about the spring shaft axis F with the spring shaft axis F aligned 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 shaft holder opening 16 is guided during assembly along an axis aligned approximately parallel to the spring shaft axis F, in particular parallel to the upper edge 11 of the building opening 5.
