Description

The present invention relates to a sliding door system with at least one running rail extending in a longitudinal direction and a door leaf guided thereon with at least one running gear, the running gear having a running carriage guided in the running rail and a fastening device connected to the running carriage via which the running gear is attached to an upper one Edge of the door leaf is attached.

Such sliding door systems are generally known. The door leaf is carried by the running rail via the drive so that the weight of the door leaf is transferred to the running rail via the carriage. The carriage rolls with one or more rollers in a track of the running rail.

There are sliding door systems in which the running rail has a track for the running gear, the carriage of the running gear having one or more running rollers on one side that are guided in the running track. In the case of sliding door systems of this type, during the assembly of the door leaf with the mounted running gear, it is mostly hung into the running rail from the longitudinal side of the running rail. Such a sliding door system is off, for example DE 10 2011 012 286 A1 known to the applicant.

There are also sliding door systems in which the carriages of a drive have rollers on both sides, the running rail having two parallel tracks on which the carriage rolls with the rollers. In sliding door systems of this type, the drives usually have to be pushed in on one end face of the running rail, since lateral insertion into the running rail from the longitudinal side of the running rail is not possible. Such carriages are mostly used for very large and heavy door leaves. When assembling the door leaves there is usually the problem that the door leaves are difficult to handle because of their very high weight. In one type of sliding door system, the door leaves are attached to the carriage from below, with the door leaves having to be raised. In the case of glass sliding door systems in particular, however, there is the problem that these door leaves are particularly heavy and, moreover, very sensitive, so that even a slight bump on a corner of the door leaf can lead to damage. Out DE 10 2016 202 774 a sliding door system of the type mentioned is known in which the carriage can be connected to a fastening device attached to an upper edge of the door leaf by sliding in the longitudinal direction of the running rail. The connection between the carriage and the fastening device allows a height adjustment in that the carriage and the fastening device can be moved relative to one another in the height direction.

In the case of sliding door systems, in which the door leaf with the mounted drive is hung from the longitudinal side of the running rail into the running rail during assembly, the running gear is often swiveled into the running track underneath a safety catch formed by part of the rail. For this purpose, the door leaf must be placed at an angle from the long side of the running rail, the door leaf extending at an angle away from the long side. In order to enable such a pivoting, however, sufficient space must be provided in the running rail for the pivoting of the carriage. The track is therefore mostly at a relatively large distance from a wall to which the running rail is attached, so that the door leaf, which is guided in the running rail, also has a relatively large distance from the wall. A hanging of the door leaf in another direction, in which the door leaf extends obliquely into the side facing away from the longitudinal side, is not possible due to the wall along which the door leaf runs.

It is therefore the object of the present invention to provide a sliding door system in which a simple construction of the drive is realized, wherein a small wall distance between the door leaf and a wall on which the sliding door system is arranged can be realized.

The sliding door system according to the invention has at least one running rail extending in a longitudinal direction and a door leaf guided thereon with at least one drive, the drive having a carriage guided in the running rail and a fastening device connected to the carriage. The drive is fastened to an upper edge of the door leaf via the fastening device. The carriage is fastened to the fastening device via at least one fastening means, the at least one fastening means pressing the carriage and the fastening device against one another in the longitudinal direction of the running rail, with at least one projection being arranged on the carriage which extends in the longitudinal direction of the running rail and into a recess engages the fastening device and / or wherein at least one projection is arranged on the fastening device, which extends in the longitudinal direction of the running rail and engages in a recess of the carriage.

The sliding door system according to the invention makes it possible in a simple manner that the carriage can first be inserted into a compactly designed running rail and then moved in the longitudinal direction of the running rail to be connected to the fastening device of the door leaf. The at least one projection, which extends in the longitudinal direction of the running rail, engages in the corresponding recess so that the weight force can be transmitted from the fastening device to the carriage via a form fit. Since the carriage is inserted into the running rail without the door leaf attached to it, the running rail can be made very compact, since no or almost no space is required within the running rail for pivoting the carriage.

The carriage is guided in the running rail in that at least one running roller can roll on at least one running track of the running rail. It is preferably provided that the carriage has one or more rollers on only one side, which are guided in a track of the running rail. In this way, a particularly compact design of the running rail and running gear is possible. The running rail can have a rail projection which extends in the longitudinal direction of the running rail and which forms a securing device for the carriage. The rail projection is arranged, for example, in the vertical direction above the track. The distance in the vertical direction between the rail projection and the track can be selected so that the roller can be swiveled in under the rail projection when the carriage is inserted. The rail projection can also be arranged so close to the track that when the carriage is in the inserted state, there is only a distance of a few millimeters from the roller, so that pivoting is not possible. In this case the carriage is to be inserted from a longitudinal end of the running rail.

The sliding door system according to the invention also has the advantage that the at least one projection that engages in the recess is independent of the at least one fastening means, so that the fastening means is used essentially for pressing the carriage and fastening device against each other in the longitudinal direction of the running rail, but largely does not transfer any weight force from the fastening device to the carriage.

In the context of the invention, the door leaf is understood to mean the plate-shaped part of the sliding door / the door leaf. The drive is an add-on part on the door leaf and is therefore not to be understood as part of the door leaf. The at least one fastening means can be a screw, for example. The at least one fastening means can preferably be operated from one side of the drive.

The sliding door system according to the invention is particularly suitable for glass doors in which the door leaf consists of glass or largely of glass.

It is preferably provided that the at least one fastening means extends in the longitudinal direction of the running rail. In this way, the sliding door system according to the invention can be installed in a particularly advantageous manner. After hanging in the running rail, the carriage is displaced along the running rail in the direction of an erected door leaf with a fastening device until the at least one projection engages in the recess. The fastening means (s) can then conveniently be inserted and operated from the end face of the drive, that is to say from a side of the drive running transversely to the longitudinal direction of the running rail.

It is preferably provided that the at least one projection tapers towards one end, the recess having a shape adapted to the at least one projection. It is thereby achieved that when the projection engages in the recess, a guiding function is realized between the recess and the projection, whereby the carriage and the fastening device are aligned with one another. In this way, for example, the fastening device can be used in a simple manner.

It can preferably be provided that the projection tapers at a taper angle, the recess tapering at the same angle.

In the case of a tapering projection, it can also be provided that the maximum diameter of the projection is greater than the maximum diameter of the recess. In this way it can be achieved that the projection cannot be completely inserted into the recess and thus when the drive is fastened to the fastening device, the connection between the drive and the fastening device takes place exclusively via the fastening means and the at least one projection engaging in the at least one recess . In other words: the opposing surfaces of the drive and the fastening device, on which the at least one projection or the at least one recess is arranged, do not touch when the drive is fastened to the fastening device, but rather a small gap remains.

It can also be provided that the at least one projection in the longitudinal direction of the running rail has a length which is greater than the extent of the recess or one of itself tapering, adapted to the projection section of the recess in the longitudinal direction of the running rail. If the recess is configured as a blind hole, the projection thus has a greater length than the depth of the recess. According to the invention, it can thus also be achieved that the projection cannot completely dip into the recess, so that a connection between the fastening device and the carriage takes place essentially via the projection and the recess and a small gap remains between the opposing surfaces of the carriage and the fastening device .

This ensures that in the fastened state between the fastening device and the carriage no or almost no play exists or can arise and the weight force can advantageously be transmitted to the recess via the projection.

The invention can in particular provide that a plurality of projections are provided, each of which engages in a recess. For example, four projections and recesses can be provided. In the case of a plurality of projections which each engage in a recess, it is preferably provided that the at least one fastening means is arranged between two of the projections in order to prevent tilting between projections and recesses.

In a preferred embodiment of the invention it is provided that the at least one fastening means has an operating element on its side facing a first side edge of the door leaf in the longitudinal direction of the running rail. As a result, the fastening means can be operated in a particularly simple manner. In the embodiment of the fastening means, the operating element can be a screw, for example the screw head.

It is preferably provided that the carriage is arranged on the side of the fastening device facing a first side edge of the door leaf in the longitudinal direction of the running rail. In the case of a sliding door system in which two bogies are used, the bogies can thus each be spaced very far from one another and arranged very close to the respective side edge, whereby the door leaf can be guided particularly well.

It is preferably provided that the at least one fastening means extends through the carriage. The at least one fastening means can thus be fastened in a particularly simple manner by being inserted into the carriage from the side of the carriage facing away from the fastening device and pushed through it until the fastening means can engage in the fastening device. Furthermore, in this way the fastening means can be operated particularly easily on the side facing the first side edge of the door leaf in the longitudinal direction of the running rail.

It is preferably provided that the sliding door system has a roller block with two rollers, which is arranged on the carriage, the roller bracket being pivotably mounted on the carriage via an axis extending horizontally in a direction transverse to the longitudinal direction of the running rail. Such a roller block advantageously enables unevenness to be compensated for, so that the door leaf can be guided in the running rail with particular smoothness and it is ensured that both rollers carry approximately the same load.

The design of a sliding door system with a carriage with a roller block with two rollers also has independent inventive significance and can also be implemented independently of the manner in which the carriage is attached to the fastening device.

The invention thus also relates to a sliding door system with at least one running rail extending in a longitudinal direction and a door leaf guided therein with at least one drive, the drive having a carriage guided in the running rail and a fastening device connected to the carriage, via which the drive is attached to a upper edge of the door leaf is attached, wherein a roller bracket with two rollers is arranged on the carriage, the roller bracket being pivotably mounted on the carriage via an axis extending horizontally in the direction transverse to the longitudinal direction of the running rail.

It is preferably provided that the roller block has a plate on which the rollers are rotatably mounted, the axle between the rollers engaging the plate. As a result, on the one hand, a small extension of the roller block in a horizontal direction transverse to the longitudinal direction of the running rail is made possible, as a result of which a compact design of the carriage can be realized. Furthermore, by engaging the axle between the rollers on the plate, the roller block functions in the manner of a rocker. If one of the rollers is lifted off the track due to an unevenness or, for example, dirt, the other roller is pushed in the direction of the track, so that it is ensured that the carriage is always in contact with one roller. A particularly advantageous guidance of the carriage in the running rail is thereby possible.

In a preferred embodiment of the invention it is provided that the axis has a taper, the at least one fastening means cooperating with the taper of the axis and blocking the axis in a horizontal direction transverse to the longitudinal direction of the running rail. In other words: the fastening means, which is provided for fastening the carriage to the fastening device, also ensures that, in the assembled state, the axis cannot slip out in a horizontal direction transverse to the longitudinal direction of the running rail. This can take place in that the at least one fastening means is arranged orthogonally to the axis and extends at least partially into the recess area of the axis formed by the taper. For example, the axle can be attached via a nut. If this should accidentally come loose, the fastening means prevent the axle from slipping out of the carriage, which prevents the door leaf from tilting out of the running rail.

In a particularly preferred embodiment it can be provided that two fastening means are provided which run parallel and are arranged vertically one above the other. In such a configuration of the sliding door system it can be provided that the axis extends between the two fastening means, both fastening means cooperating with the taper. As a result, the axis can be held in a particularly advantageous manner.

It is preferably provided that the carriage has a height adjustment device by means of which the at least one roller can be adjusted in the vertical direction.

It can be provided that the height adjustment device is at least partially formed by an eccentric course of a section of the axis of the roller. In an embodiment of the sliding door system with a roller block with two rollers mounted on an axle, it can also be provided that the height adjustment device is formed by an eccentric course of a section of this axle. The entire roller block is then adjusted in the vertical direction.

The roller or the roller block can be easily adjusted via an eccentric course of the axis by rotating the axis. As a result, the roller or the roller block moves in comparison to the other parts of the carriage in the vertical direction. In this way, the height adjustment device can be designed in a structurally simple manner.

In a sliding door system in which the carriage has one or more rollers that are not arranged on a roller block, the axes of these rollers can be secured in a manner comparable to that described above with regard to the embodiment with roller block, by means of the at least one fastening means .

Since when adjusting the height by means of the height adjustment device according to the invention via an eccentric course of a section of the respective axis, the fastening of the axis must be released, the at least one fastening means can ensure that the axis cannot slip out of the carriage when the height device is adjusted.

In the sliding door system according to the invention it is preferably provided that the fastening device is designed as a clamping device which has clamping jaws on both sides of the door leaf, one clamping jaw being arranged on a main body of the fastening device and one clamping jaw being formed by a clamping plate fastened to the main body. By providing the fastening device as a clamping device, the fastening device can be fastened to a door leaf in a simple manner without, for example, fastening holes having to be provided on the door leaf. As a result, the fastening device can be used in a particularly advantageous manner in connection with a door leaf that is entirely or partially made of glass. As a result, the fastening device is particularly simple in construction.

The design of the fastening device as a clamping device also has independent inventive significance and can also be implemented independently of the previously described configuration of the sliding door system with a special fastening of the carriage to the fastening device or the embodiment of the carriage with a roller block.

The invention thus also relates to a sliding door system with at least one running rail extending in a longitudinal direction and a door leaf guided thereon with at least one carriage, the carriage having a carriage guided in the running rail and a fastening device connected to the carriage, via which the carriage is attached to a carriage upper edge of the door leaf is attached, wherein the fastening device is designed as a clamping device which has clamping jaws on both sides of the door leaf, wherein a clamping jaw is arranged on a main body of the fastening device and a clamping jaw is formed by a clamping plate fastened to the main body.

It is preferably provided that the clamping plate is made of steel and the main body is preferably a cast part. For example, the main body can be designed as a zinc die-cast part.

As a cast part, bodies are particularly easy to manufacture. In contrast to steel, however, cast parts usually have only a low level of elasticity. By providing a clamping plate made of steel it can thus be achieved that at least one of the parts that form a clamping jaw is elastically deformable to a certain extent. This ensures that a certain compensation can take place when the door leaf, which is clamped between the clamping jaws, changes. For example, the steel plate is elastically shaped by the clamping force. If, for example, the door leaf is made of laminated safety glass (VSG), it can happen that the door leaf in the area of the clamping is gradually thinner due to a change in the thickness of the film under pressure. In this case, the steel plate reshapes accordingly so that the clamping force remains essentially constant and the door leaf is held securely on the fastening device. By making the clamping plate out of steel, the material thickness on this side of the drive can also be reduced, so that it can be made particularly compact. In this way, for example, a very small wall clearance of the door leaf can be achieved.

It is preferably provided that the clamping jaw formed by the main body has a pressure plate which can be adjusted in the direction of the door leaf to generate the clamping force and which presses against the door leaf. For example, the pressure plate, which can be made of steel, is fastened by means of screws via which the pressure plate can be adjusted. This allows the clamping force to be set precisely. In the exemplary embodiment with the pressure plate arranged on the main body, the clamping force generated by this is countered by the clamping plate and the previously described elastic deformation of the clamping plate can take place.

A glass insert can be provided on the clamping jaws, for example on the clamping plate and the pressure plate, which protects the door leaves made of glass.

It is preferably provided that the clamping plate rests against a fastening surface of the fastening device, the fastening surface running at an acute angle to a main plane of the door wing when it is fastened to the door leaf. The fastening surface is thus inclined towards the main plane of the door leaf. It is thereby achieved that the clamping plate, which is in contact with the fastening surface, also runs at an acute angle to the main plane of the door leaf, so that the clamping plate is in contact with the door leaf at the lowest possible area. The clamping plate can thus in a particularly advantageous manner form a counter-bearing for the clamping force generated, for example, by the pressure plate. Such a configuration of the fastening device moreover enables elastic deformation of the clamping plate in an advantageous manner, since the clamping force acts on the clamping plate with a relatively long lever. The design of the fastening device according to the invention enables a particularly stable fastening of the door leaf to the fastening device.

The clamping plate can be attached to the main body by means of screws, for example. The screws can for example penetrate the clamping plate and engage in the fastening surface. It can be provided that the screws do not run orthogonally to the fastening surface and thus also not orthogonally to the clamping plate, but rather slightly inclined so that the screws rest with their lower part of the screw head on the clamping plate. This can ensure that the screws counter the clamping force in a particularly advantageous manner.

In the sliding door system according to the invention, a damper unit arranged in the running rail with a retraction function and with a coupler arranged on the drive can also be provided, the coupler engaging with an engaging part of the damper unit in a latching manner, the damper unit initially braking the door leaf when moving towards an end position and then drives into the end position and wherein the coupler can be adjusted in a horizontal direction transverse to the longitudinal direction of the running rail and / or in the vertical direction. The provision of the damper unit ensures that the door cannot be moved to its end position without braking, but is braked gently and moved into the end position at a defined speed. By providing a coupler that is adjustable in the horizontal direction transversely to the longitudinal direction of the running rail and / or in the vertical direction, the coupler can advantageously be adjusted to the damper unit arranged in the running rail, so that even in installation situations in which the running rail can not be optimally arranged, but for example runs obliquely in any direction, is ensured, that the coupler can engage with the damper unit in a latching manner.

The design of the sliding door system with the damper unit arranged in the running rail and the adjustable coupler also has independent inventive significance and can also be implemented independently of the previously described exemplary embodiments of the sliding door system.

The invention thus also relates to a sliding door system with at least one running rail extending in a longitudinal direction and a door leaf guided thereon with at least one carriage, the carriage having a carriage guided in the running rail and a fastening device connected to the carriage, via which the carriage is attached to a carriage The upper edge of the door leaf is attached, the sliding door system having a damper unit arranged in the running rail with a pull-in function and a coupler arranged on the drive, the coupler engaging with an engaging part of the damper device in a latching manner, the damper unit initially moving the door leaf towards an end position brakes and then drives into the end position, the coupler being adjustable in a horizontal direction transverse to the longitudinal direction of the running rail and / or in the vertical direction.

The coupler can be adjusted in a horizontal direction transverse to the longitudinal direction of the running rail, for example, by arranging spacers, which can be plate-shaped, for example, between a contact surface for the coupler and the coupler when fastening the coupler. For a high degree of flexibility, for example, several plates can be provided so that one or more of the plates can be installed to adjust the coupler as required.

The adjustment of the coupler in the vertical direction can take place, for example, via an elongated hole. There is also the possibility that the coupler can be fastened in two different positions in the vertical direction.

The coupler can be fastened using screws, for example. The coupler can, for example, be pulled onto a contact surface via the screws. When the coupler is adjusted in the horizontal direction, the spacer, for example one or more of the plates, is now arranged between the coupler and the contact surface, so that screws pull the coupler against the spacer. For an adjustment in the vertical direction, for example, several holes can be provided into which the screws are inserted.

In 1 is a sliding door system according to the invention 1 shown schematically in a perspective view.

The sliding door system according to the invention 1 has a running rail extending in the longitudinal direction 3 in which a door leaf with an in 1 drive not shown 4th is led. The longitudinal direction is indicated by a double arrow. The running rail 3 has an essentially C- shaped cross-section, with a diaphragm 5 the inside of the track 3 is hidden from the viewer.

The running rail 3 forms a career 7th for the drive 4th . Above that of the career 7th is a rail protrusion 6th arranged, which extends in the longitudinal direction of the running rail 3 extends and a safety catch for the door leaf 100 forms.

In 2 is the door leaf 100 with two drives attached 4th shown in a schematic side view. The drives 4th are on an upper edge 100a of the door leaf 100 arranged.

The drive 4th consists of a carriage 9 and a fastening device 11 . The fastening device 11 is stuck on the door leaf 100 attached. The carriage 9 is via fasteners not shown 27 on the fastening device 11 attached.

How out 2 can be seen are the drives 4th arranged in mirror image, that is, the carriage is in each case on the respective outer edge 100b of the door leaf 100 facing side of the fastening device 11 arranged. This allows the carriage 9 very close to the outer edge 100b be arranged, whereby between the carriages 9 a large distance can be created, whereby a particularly smooth running of the door leaf 100 can be reached.

The trolleys 9 each have two rollers 13th on that on a pulley block 15th are rotatably attached. The roller block 15th is about an axis 17th stored, with the axis 17th between the two rollers 13th is located. In particular, the roller block 15th be plate-shaped. About the storage of the axle 17th the roller block can perform a rocker-like movement so that when one of the rollers 13th the other roller threatens to lift off 13th is pushed towards the raceway. The castors 13th can on the career path 7th the running rail 3 roll off. Through the design of the carriage 9 can the door leaf 100 with particularly smooth running in the running rail 3 and it is ensured that both rollers 13th carry approximately the same load.

The in 1 Rail projection shown 6th can with one on the castors 13th adjusted vertical distance from the track 7th be arranged so that the castors 13th when inserting the carriage 9 can be swiveled under the rail projection. In the assembled state of the door leaf 100 prevents the rail protrusion 6th that the casters 13th can jump out of the career path.

In 3a and 3b are detailed representations of the fastening device 11 and the carriage 9 shown to illustrate how the carriage 9 on the fastening device 11 is attached.

On the carriage 9 are several protrusions 19th arranged. The fastening device 11 points to the protrusions 19th adapted recesses 21st on. The carriage 9 can in the running rail 3 be swiveled in so that the rollers 13th on the track 7th are arranged. Furthermore, the fastening device 11 at the top 100a of the door leaf 100 be attached and the door leaf 100 below the running rail 3 to be ordered. Now the carriage can 9 be moved in the longitudinal direction of the running rail. The longitudinal direction of the track is in 3a marked by the double arrow. When the carriage hits 9 on the fastening device 11 can the protrusions 19th into the recesses 21st immerse. By making the protrusions 19th taper in the longitudinal direction of the running rail and the recesses 21st one on the protrusions 19th have adapted shape, a guiding function takes place between projections 19th and recesses 21st so that the carriage 9 and the fastening device 11 are aligned with each other. About the fasteners 27 the carriage can now 9 on the fastening device 11 attached. The fasteners 27 can, for example, be screws that extend in the longitudinal direction of the running rail and through the carriage 9 extend through. This allows the fastener 27 advantageously from the outer sides of the door in the longitudinal direction of the running rail 100 to be served.

How out 3a it can be seen, have the projections 19th in the longitudinal direction of the running rail a length which is greater than the extent of the recesses 21st in the longitudinal direction of the track 3 . This ensures that the projections 19th when attaching the carriage 9 on a fastening device 11 not completely into the recess 21st immerse. Between the opposing surfaces 9a , 11a of the carriage 9 and the fastening device 11 a small gap remains in the fastened state. This ensures that forces are transverse to the longitudinal direction of the running rail 3 exclusively over the protrusions 19th and the recesses 21st as well as the fasteners 27 be included.

In 3b Figure 3 is a plan view of the surface 9a of the carriage 9 shown. How out 3b As can be seen, there are four protrusions 19th intended. Between every two protrusions 19th is a through hole 23 for the fastener 27 intended. In that the fasteners 27 between each of the projections 19th arranged ensures that it is when securing the carriage 9 on the fastening device 11 not to a tilt between a projection 19th and a recess 21st can come.

In 4th is the carriage 9 shown in a partially cut detailed representation.

The axis 17th extends through a bearing bore 24 in the carriage 9 through which the roller block 15th is stored. On the roller block 15th opposite side of the carriage 9 is the axis 17th by means of a mother 25th secured. The axis also has a taper 17a on. The through holes 23 for the fasteners 27 are arranged so that in the through holes 23 inserted state of the fasteners 27 the fasteners 27 partially in the vertical direction due to the taper 17a formed recess area of the axis 17th extend and the axis 17th block in their longitudinal direction. This means that the axle can slip out 17th from the bearing bore 24 be prevented.

Furthermore, the axis 17th a section 17b with an eccentric course. In this way, a height adjustment can be formed. After loosening the nut 25th can the axis 17th be rotated, making the roller block 15th is raised or lowered. Then the axis 17th in the appropriate position by means of the nut 25th secured.

In the case of the sliding door system according to the invention, in particular one in the running rail 3 arranged damper unit be provided with retraction function. The door leaf can be opened via the damper unit with retraction function 100 when moving to one of the end positions are initially braked and then driven into the end position. The end position is, for example, a stopper against which the carriage 9 in the end position.

To interact with the damper unit is on the drive 4th a coupler 29 arranged. The coupler 29 can interact with an engaging part of the damper unit, whereby the damper unit exerts a force on the drive 4th can exercise.

In the 5a and 5b are detailed representations of the coupler 29 shown.

Preferably the coupler is 29 on the fastening device 11 arranged.

The coupler 29 is by means of two screws 31 on the fastening device 11 attached. The screws pull the coupler in the direction of a contact surface 35 . The coupler can be adjusted in height 29 be provided by the screws 31 for example, are arranged in an elongated hole which extends in the vertical direction. There is also the possibility that for each screw 31 a plurality of holes lying one above the other in the vertical direction are provided so that the height of the coupler can be adjusted 29 can be done by making different holes for the screws 31 to get voted.

Furthermore, the coupler 29 in a horizontal direction transverse to the longitudinal direction of the running rail 3 understand.

How out 5b it can be provided that spacers in the form of thin plates 33 between the coupler 29 and the contact surface 35 to be ordered. By adding or removing one of the panels 33 can thus change the position of the coupler 29 can be changed in the horizontal direction across the running rail.

By setting the coupler 29 it is ensured that even if the running rail is not one hundred percent straight because of, for example, inclined walls, it is ensured that the coupler 29 cooperates reliably with the damper unit with retraction function.

In 6th is a schematic sectional view of the fastening device 11 shown.

The fastening device 11 is designed as a clamping device and points on both sides of the door leaf 100 Jaws 37a , 37b on. One jaw 37a is thereby through a main body 11b formed the fastening device and know a pressure plate adjustable by means of screws 38 on. The second jaw 37b is through a clamping plate 39 educated.

The pressure plate 38 and the clamp 39 can for example consist of steel, whereas the main body 11b is a casting.

The clamp 39 is on a mounting surface 11c attached, the attachment surface at an acute angle to the main plane of the door leaf 100 runs. This causes the clamping plate to run 39 also at an acute angle to the main plane of the door leaf so that, as from 6th can be seen, the clamping plate 39 with their lower end on the door leaf 100 is applied. The pressure plate 38 pushes against the door leaf 100 to create a clamping force. By having the clamping plate 39 with their lower end on the door leaf 100 is applied, the clamping force also acts on the clamping plate at this lower end 39 .

By having the clamping plate 39 is made of steel, this can be due to the elastically deform the acting force. This has the advantage that it can be provided that when fastening the clamping plate 39 this is due to the pressure against the door leaf 100 slightly elastically deformed. In the case of door leaves made of anti-burn glass, for example, it can happen that a film located in the glass thins over a certain period of time due to the pressure, which leads to a decrease in the thickness of the door leaf 100 can come. Due to the elastic deformation of the clamping plate 39 this change in thickness can be compensated so that the same or approximately the same clamping force on the door leaf is always applied 100 is applied.

In one embodiment of the door leaf 100 made of glass can between the pressure plate 38 and the door leaf 100 or between the clamping plate 39 and the door leaf 100 a glass side dish each 43 be provided to protect the glass.

The clamp 39 is about screws 41 on the mounting surface 11c attached. The screws 41 can have an inclined course, that is, they are not orthogonal to the fastening surface 11c and the clamping plate 39 run away. This ensures that the screws 41 for example with its lower end of the screw head against the clamping plate 39 issue. In this way it can be ensured in a particularly advantageous manner that in the event of an elastic deformation of the clamping plate 39 the screws 41 not threaten to loosen up.

By means of the sliding door system according to the invention it can be achieved in particular that a door leaf 100 with a very short distance to a wall on which the running rail is located 3 is attached, can be arranged as the running rail 3 can be made very compact and by means of the drive according to the invention 4th the door leaf very close to the running track 7th and can therefore be placed very close to the wall.
