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, by means of which the running gear is connected to an upper one Edge of the door leaf is attached.

Such sliding door systems are generally known. There are sliding door systems in which the running track has a running track for the running gear, the running carriage of the running gear having on one side one or more rollers which are guided in the running track. With sliding door systems of this type, when the door leaves are mounted with the drive installed, they are usually hooked into the running rail from the long side of the running rail.

There are also sliding door systems in which the running carriages of a running gear have running rollers on both sides, the running rail having two parallel running tracks on which the running carriage rolls with the running rollers. In sliding door systems of this type, the drives usually have to be inserted on one end of the running rail, since lateral insertion into the running rail from the long side of the running rail is not possible.

When installing the door leaves in the running track, there is usually the problem that very large door leaves have a high weight, so that the Handling when hanging the door leaf from the long side of the track is problematic. With sliding door systems, where the drive is already inserted in the running rail, there is the problem that the door leaf must now be connected to the drive during assembly. The problem exists in particular in the case of glass sliding door systems in which the door leaves are made of glass, since these are particularly heavy and, moreover, are very sensitive, so that a slight impact on a corner of the door leaf can already lead to damage. Overall, the assembly of the known sliding door systems is problematic due to the handling of the door leaves.

A sliding door system is out EP 0 940 542 A2 known. US 904 373 A , CH 702 258 A1 , US2006 / 0236613A1 and EP 2 886 769 A1 disclose sliding door systems, in each of which a carriage can be moved in the longitudinal direction of a running rail in order to be connected to a fastening device arranged on the upper edge of a door leaf. US 2006 / 0236613A1 discloses the features of the preamble of claim 1.

It is therefore the object of the present invention to provide a sliding door system, the assembly of which is simplified. Furthermore, it is the object of the present invention to create a simplified method for assembling such a sliding door system.

The sliding door system according to the invention is defined by the features of claim 1. The method according to the invention is defined by the features of claim 12.

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 running gear, the running gear having a running carriage guided in the running rail and a fastening device connected to the running carriage. The drive is fastened to an upper edge of the door wing via the fastening device. The carriage can be moved in the longitudinal direction of the running rail for connection to the fastening device in the state inserted into the running rail and can be brought into contact with the fastening device, the running carriage having a contact surface arranged in a longitudinal direction of the running rail on the side facing the fastening device on a mating contact surface of the Fastening device is present and can be fastened to the fastening device via at least one fastening means.

Thus, the sliding door system according to the invention enables a particularly simple assembly, since the door leaf can be arranged with the fastening device fastened to the door leaf underneath the running rail and assembly can be carried out in a simple manner by pushing the carriage in the longitudinal direction of the running rail towards the fastening device and is fastened to the fastening device by means of the at least one fastening means. In the sliding door system according to the invention, two or more fastening means can also be provided, for example. Screws, for example, can be provided as fastening means. The carriage is arranged essentially above the door leaf and can thus be advantageously moved along the running rail in order to be brought into contact with the fastening device. By providing a contact surface arranged on the side facing the fastening device and a mating contact surface on the fastening device, the carriage and the fastening device can be connected in a particularly simple manner, the contact surface and the mating contact surface being pressed against one another by the fastening means. The contact surface and the counter-contact surface form a frictional connection for fastening. This has the advantage that after loosening the fastening means, the contact surface and the counter-contact surface can slide freely one above the other when the height is adjusted. The contact surface and the counter-contact surface also ensure that the carriage and the fastening device for fastening are aligned with one another. Centering means can also be provided which support the alignment of the contact surface and counter-contact surface. Of course, in a sliding door system according to the invention it can also be provided that the door leaf has several Is guided drives, each having a carriage and a fastening device.

It is preferably provided that the at least one fastening means extends in the longitudinal direction of the running rail. Such fasteners have been found to be particularly advantageous. Furthermore, it can be achieved with such a construction that the fastening means are essentially loaded under tension.

The at least one fastening means preferably has an operating element on its side facing the first side edge of the door leaf in the longitudinal direction of the running rail. As a result, the carriage can be fastened to the fastening device in a particularly advantageous manner by operating the fastening means from the end face of the door leaf. The sliding door system according to the invention can thus provide, in particular in the state of the carriage attached to the fastening means, that the at least one fastening means extends in the longitudinal direction of the running rail and preferably has an operating element on its side facing in the longitudinal direction of the running rail on the first side edge of the door leaf.

Such a design of the sliding door system is particularly advantageous if the drive is as close as possible to the first side edge of the door leaf. It can therefore be provided that the drive is arranged on the door leaf with a predetermined distance D from the first side edge of the door leaf extending in the longitudinal direction of the running rail. The distance D is measured from the side edge of the door leaf to the edge of the drive unit facing the side edge of the door leaf. The predetermined distance D can be, for example, a maximum of 10% of the door leaf width. This ensures that the at least one fastening means for fastening the carriage to the fastening device can be conveniently operated from the first side edge of the door leaf.

In a particularly preferred embodiment of the invention, it is provided that the carriage has a height adjustment by means of which the carriage and the fastening device can be adjusted relative to one another in the vertical direction. The height of the door leaf can thus be adjusted in an advantageous manner by means of the height adjustment. It can be provided that the height adjustment takes place before the at least one fastening means firmly connects the carriage and the fastening device to one another. After the height adjustment, the carriage and fastening device can then be braced using the fastening means. According to the invention it is provided that the carriage is arranged on the side of the fastening device facing the first side edge of the door leaf in the longitudinal direction of the running rail, the fastening means extending through the carriage. In this exemplary embodiment, the fastening means engages in the fastening device. The fastening means can either releasably engage in the fastening device, for example by means of a screw thread, or can also be firmly connected to the fastening device, the fastening means having a fastening part on the side of the carriage facing away from the fastening device, by means of which the carriage is pressed against the fastening device . The fastening means can be, for example, screw bolts which are inserted through the carriage and engage in a thread in the fastening device. Alternatively, studs can also be provided as fastening means, which are fixedly arranged on the fastening device and onto which the carriage is pushed. On the side facing away from the fastening device, screw nuts, for example sleeve nuts, can be provided as the fastening part, which press the carriage against the fastening device. It is thus achieved that the carriage, which is at least partially arranged in the longitudinal direction of the running rail next to the fastening device is very close to the first page margin. If the door leaf is guided with two carriages, it can be achieved that the distance between the carriages in the longitudinal direction of the running rail is chosen to be very large, whereby a particularly advantageous guidance of the door leaf is achieved. With such an arrangement it can of course also be provided that the fastening means engages in the carriage and penetrates the fastening device, for example through a part forming the counter-contact surface.

It can be provided that the fastening means in the carriage or in the fastening device is guided through an elongated hole. In this way, the carriage can be adjusted relative to the fastening device in the vertical direction by means of the height adjustment in a simple manner, since the carriage is guided on the fastening means and has a corresponding freedom of movement in the vertical direction through the elongated hole.

The height adjustment can have an adjusting screw extending through the carriage, which presses against an inclined flank of the fastening device, the adjusting screw extending through the carriage and having an operating element on its side facing the first side edge of the door leaf. The adjusting screw can have, for example, a ball head that presses against the oblique flank. The sloping flank can be made of a different material than the fastening device, which is made, for example, of aluminum, for example of stainless steel. In one embodiment, in which the fastening device has two clamping jaws, the inclined flank can be formed by inclined surfaces on the clamping jaws. When attached to a door leaf, the inclined surfaces of the clamping jaws can be spaced apart from one another, so that the inclined flank has a gap. A ball head of the adjusting screw can advantageously be guided over the gap. Such a height adjustment has proven to be particularly advantageous. The provision of an adjustment screw allows a very fine height adjustment to be made by turning the adjustment screw. Furthermore, by means of such an adjusting screw, it can be achieved in an advantageous manner that when the fastening means is tightened, it is braced, so that part of the weight is also absorbed by the adjusting screw of the height adjustment. As a result, the load can be divided between the at least one fastening means and the adjusting screw. The adjusting screw can have a stop over which the adjusting path of the adjusting screw is limited. This prevents the adjustment screw from being screwed in too far, which could push the carriage away from the fastening device.

In the sliding door system according to the invention it can also be provided that the fastening means or the fastening means and the adjusting screw of the height adjustment extend through the fastening device, for example through a part forming the counter-contact surface, and engage in or rest on the carriage. It can be provided that the carriage is arranged on the side of the fastening means facing away from the first side edge of the door leaf.

It is preferably provided in the invention that the fastening device has a flange projection which, in the longitudinal direction of the running rail, engages in a recess in the running carriage, preferably in a form-fitting manner. In this way, the fastening device is centered relative to the carriage, so that the fastening means can engage in the fastening device in an advantageous manner. It can be provided that the fastening means engages in the flange projection. The flange projection can form the mating contact surface. In addition, the fastening device can have projections which, in a state attached to the door leaf Fastening device form a gap to the door leaf. Centering projections of the drive can be guided in this gap, which results in additional centering.

In a preferred embodiment of the invention it is provided that the fastening device is designed as a clamping device which has clamping jaws on both sides of the door leaf. Such a configuration is particularly advantageous in the case of glass door leaves, since the fastening device can be fastened by clamping to the door leaf and thus costly bores on the glass are avoided. The projections can be arranged on the clamping jaws on the side facing the first side edge.

In a preferred embodiment of the invention it is provided that the carriage has an adapter element which is inserted in a through recess in the carriage, the fastening means being guided in the adapter element. Such an adapter element is advantageous because the parts in which the fastener is guided and against which the fastener lies for tightening can be made of a different material than the rest of the carriage. For example, the elongated hole can be arranged in the adapter element. Furthermore, the adjusting screw of the height adjustment can extend through the adapter element. Because the adapter element can be made from a different material than the rest of the carriage, material can be used on the one hand that enables very high processing accuracy, for example to produce the elongated holes with high accuracy. The adapter element can also be replaced in a simple manner if the adapter element shows signs of wear due to, for example, the fastening means. In this case, it is not necessary to replace the entire carriage, only the adapter element can be replaced. The adapter element can, for example, have a pressure plate on the side facing the first side edge, via which the Adapter element is fastened in the carriage and forms a contact surface for the fastener or fasteners. The adapter plate can be made of a low-wear material, for example steel, which prevents the fastener (s) from being pressed in when the carriage is being fastened.

The adapter element can be positively received in the carriage. This ensures that, for example, the slot for the fastener is aligned with the corresponding engagement point for the fastener on the fastener when connected to the fastener.

The adapter element can have a projection which engages in a gap of the fastening device to form an anti-rotation device. Alternatively, the anti-rotation device can also be provided by the centering projections on the carriage, which interact with the projections of the fastening device. In the case of sliding door systems, the structural specifications can sometimes result in the running tracks being twisted after installation. This can result in twisting movements that must be compensated for by the drive. In order to ensure that there is no relative rotation between the carriage and the fastening device, the anti-rotation device provides a positive connection that prevents this. Furthermore, the anti-rotation device ensures an advantageous alignment of the carriage and fastening device during assembly and prevents relative rotation between the carriage and fastening device when the fastening means is tightened.

The sliding door system according to the invention preferably has a damper unit with a pull-in function and a coupler which engages with an engaging part of the damper unit, the damper unit first braking the door leaf when moving in the direction of an end position and then drives into an end position. Such a damper unit with pull-in function ensures that the door leaf is reliably moved into the closed position, for example when the door is closed.

It can be provided that the damper unit extends in the longitudinal direction of the running rail and is arranged on the running carriage on the side facing away from the first side edge of the door leaf and that the coupler is fastened to the running rail. The coupler can, for example, form a structural unit with a limiting device. In the sliding door system according to the invention it can be provided that the engagement part of the damper unit is directed upwards. The coupler thus runs above the door leaf. As a result, the running rail can be narrow in a visually appealing manner. The coupler can be designed, for example, as an elongated arm which extends in the longitudinal direction of the running rail. At its end facing away from the limiting device, this can have a centering stone which engages in a groove in the running rail. This ensures that the coupler is centered and cannot deflect laterally or upwards when interacting with the damper unit. This ensures reliable operation.

The centering stone can be guided in an elongated hole. As a result, the position of the centering stone can be varied in the longitudinal direction of the coupler. Since the groove in which the centering block engages is also used for receiving a screw head of a fastening screw of the running rail, the variable position of the centering block ensures that it can engage reliably in the groove and is not in the position of a fastening screw.

The coupler can be designed as an elongated arm with a recess at a first end, with which the coupler interacts with the engaging part. With the second end facing away from the recess, the arm is at one Limiting device attached. The limiting device can engage in the running rail and be clamped in it. The coupler is thus fixed in the running rail via the limiting device.

Conventional fastening means such as a screw or a rivet can be provided for fastening the coupler, which is designed as an arm, to the limiting device. Furthermore, a height adjustment screw can also be provided, by means of which the height of the coupler can be adjusted. For this purpose, the height adjustment screw slightly pushes the arm designed as a coupler, which means that a slight deflection of the coupler due to the weight of the coupler can be compensated for, so that the recess of the coupler is at the correct height position and does not risk colliding with the carriage .

With such a configuration of the coupler and the limiting device, a very precise adjustment of the coupler to the engaging part of the damper unit is possible.

The height adjustment screw in the coupler can have a stop, for example, so that the height adjustment is limited.

The design of the coupler with the centering stone and the height-adjustable attachment of the coupler to the limiting device also have independent inventive significance and can be implemented independently of the design of the carriage and the fastening device.

In a preferred embodiment of the invention it is provided that the damper unit has an axis which engages in the carriage. The damper unit can be connected to the carriage via the axis. A such a design has been found to be particularly advantageous.

It can be provided that the carriage has at least one roller which is arranged on a roller block, the roller block being mounted on the axis of the damper unit. Such storage is advantageous because the roller block mounted on the axis of the damper unit can perform a rotational movement with respect to the carriage frame, so that the fastening device and the carriage frame can always remain vertically aligned even with a slightly twisted running rail and the deviations of the running rail due to a rotating movement of the roller block on the axis can be compensated. Such a construction can also compensate for unevenness in a track of the running track, which can arise, for example, from dirt.

For example, it can also be provided that two roller stands are arranged on the axle. Furthermore, it can be provided that rollers are arranged on both sides of the roller block or the roller blocks. In this case, the running track has two running tracks in which the running rollers can roll.

The arrangement of a damper unit with an axis extending in the carriage, on which at least one roller with a roller block is mounted, also has independent inventive significance and can be implemented independently of the configuration of the carriage and the fastening device or the coupler and the limiting device. Thus, for example, a sliding door system can be provided 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, in which a damper unit with pull-in function is provided, which acts on the door leaf Procedure towards first decelerates from an end position and then drives into an end position, the damper unit extending in the longitudinal direction of the running rail and the damper unit having an axis which engages in the carriage, wherein a roller of the carriage is arranged on a roller block which is on the axis of the damper unit is stored. The damper unit can be attached to the carriage via the axle.

The sliding door system according to the invention can in particular be designed as a sliding glass door with glass door leaves. A plurality of door leaves can also be provided, which are guided in a plurality of running rails. For example, two drives can be arranged on each door leaf, each of which is fastened near a side edge of the door leaf. It is particularly provided that the carriage is attached to the respective fastening device on the side facing the corresponding side edge of the door.

In the sliding door system according to the invention with a plurality of door leaves, each of which is guided with two drives, it can be provided that a damper unit with a pull-in function is arranged on the drive of each door leaf in the closing direction of the door leaves. Since the individual door leaves are coupled to one another in sliding door systems with several door leaves, this prevents a single door leaf, for example the front door leaf, from having to brake all the other door leaves when the door is closed; and led into their final position. Since the damper units used only have to brake the mass of a door leaf, they can be made correspondingly smaller.

There is also the possibility that corresponding damper units are provided for both end positions of the door leaf and thus the individual ones Door leaves are braked by a damper unit both when closing and opening and guided to their end position.

When damper units are provided for both end positions, damper units can be provided, for example, on the two drives arranged on a door leaf. Of course, there is also the possibility of providing a drive on a door wing and, for example, arranging two damper units on the drive.

The design of the sliding door system with dampers for each door leaf at one or both end positions also has independent inventive significance and is independent of the previously described designs of the carriage and the fastening device or the coupler and the limiting device or the damper unit with the axis extending in the carriage feasible.

• Inserting at least the carriage into the running rail,
• Attaching the running rail to a mounting location,
• Attaching the fastening device to the upper edge of the door leaf,
• Setting up the door leaf below the track,
• Moving the carriage in the longitudinal direction of the running rail until the running carriage is in contact with the fastening device, the carriage being arranged on the side of the fastening device facing the first side edge of the door leaf in the longitudinal direction of the running rail,
• Fastening the carriage to the fastening device with the at least one fastening means, the fastening means extending through the carriage, the fastening means pressing the contact surface of the carriage arranged in the longitudinal direction of the running rail on the side facing the fastening device against the mating contact surface of the fastening device.

By means of the method according to the invention, the sliding door system according to the invention can thus be installed in a particularly simple manner, since the door leaf merely must be arranged underneath the running rail, thus avoiding costly handling of the door leaf.

The method can provide that the fastening device is arranged on the upper edge of a door leaf at a distance D 'from a first side edge of the door leaf during assembly. The distance D 'is selected such that after the carriage is fastened to the fastening device, the edge of the running gear facing the first side edge of the door leaf is arranged at a predetermined distance D. The predetermined distance D can be, for example, a maximum of 10% of the door leaf width. This ensures that the drive can be reached from the first side edge in an advantageous manner during assembly.

For example, it can be provided that the carriage is fastened to the fastening device by means of at least one fastening means extending in the longitudinal direction of the running rail. The fastening means can, for example, have an operating element on the side facing the first side edge of the door leaf, so that it can be operated advantageously from this side. The predetermined distance D provided according to the invention ensures that the fastening means can be easily reached during assembly.

In Fig. 1 A sliding door system 1 according to the invention is shown schematically in a side view. The sliding door system 1 has a door leaf 3, which is guided by means of a carriage 5 in a running rail 7 extending in the longitudinal direction. For the purpose of illustration, the running rail 7 is shown partly in section.

The carriage 5 consists of a carriage 9 guided in the running rail 7 and a fastening device 11 fastened to the carriage 9. The fastening device 11 is fastened to an upper edge 3a of the door leaf 3.

The fastening device 11 is arranged at a distance D 'from a first side edge 3b of the door leaf 3, which is selected such that the edge 5a of the drive 5 facing the first side edge 3b is spaced a predetermined distance D from the first side edge 3b. The predetermined distance D is, for example, a maximum of 10% of the width of the door leaf 3, so that the carriage 9 can be reached in an advantageous manner from the first side edge 3b.

A damper unit 12 with a retraction function is arranged on the carriage 9, which first brakes the door leaf 3 when moving in the direction of an end position and then drives it into the end position. In the in Fig. 1 position shown is the door leaf 3 immediately before an end position. A limiting device 13 in the form of a stop is arranged in the running rail 7 and forms a structural unit with a coupler 15. The coupler 15 is designed as an arm extending in the longitudinal direction of the running rail 7 and interacts with an engaging part 17 of the damper unit 12. The damper unit 12 is arranged on the carriage on the side facing away from the first side edge 3b of the door leaf 3 and extends above the fastening device 11. The engagement part 17 of the damper unit 12 is after directed above. The coupler is arranged in the running rail in such a way that it extends at least partially above the drive 5.

How best to look Fig. 2 can be seen, the carriage 9 has rollers 19 on both sides, which are guided in parallel raceways 21 of the running rail 7. The carriage 9 extends with its frame 9b through a gap 23 which is formed between the raceways 21. The fastening device 11 is designed as a clamping device and has 3 clamping jaws 25 on both sides of the door leaf. In this way, the door leaf 3 can advantageously be non-positively connected to the fastening device 11. The door leaf 3 can, for example, be a glass door leaf, so that the fastening device 11 can be fastened in an advantageous manner by clamping to the door leaf 3.

Panels 28 can be provided on the running rail 7, which at least partially visually cover the fastening device 11, as a result of which an optically appealing sliding door system 1 can be created.

The running rail 7 has a groove 7a in an upward section. When fastening the running rail 7 to a ceiling, screw heads of a screw fastening for the running rail 7 can be accommodated in this groove.

Furthermore, the coupler 15, which is designed as an arm, is guided in the groove 7a by means of a centering stone 15a. The centering stone 15a is best of all Figure 1 and 1b evident. The centering stone 15a is guided in an elongated hole 15b of the coupler 15 and can be fixed therein. The position of the centering stone 15a on the coupler 15 can be varied through the elongated hole 15b, so that the centering stone 15a can be prevented from colliding with a fastening screw of the running rail 7.

At the end facing away from the limiting device 13, the coupler 15 has a recess 15c which interacts with the engaging part 17 of the damper unit.

Due to its length and its own weight, the coupler 15 may bend slightly. In order to prevent the carriage 9 from colliding with the end of the coupler facing away from the limiting device 13 or the centering stone 15a from sliding out of the groove 7a, a height adjustment is provided on the coupler 15. For this purpose, the coupler 15 is connected to the limiting device 13 via a screw 13a. Furthermore, a height adjustment screw 13b is provided, which presses against the coupler 15 from below and thus deforms it slightly elastically. As a result, the position of the end of the coupler 15 facing away from the limiting device and the recess 15c can be adjusted.

The sliding door system 1 according to the invention enables simplified assembly, which in Fig. 3rd and 4th is shown. For clarification purposes, the Fig. 3rd and 4th the track is hidden. During assembly, the fastening device 11 is fastened to the upper edge 3a of the door leaf 3. Before or after, the running rail is fastened to its installation location. Then the door leaf is arranged below the running rail. In some installation locations, the end faces of the running rail are no longer accessible after the running rail 7 has been installed. In this case, the carriage 9 must be inserted into the running rail 7 before the running rail 7 is installed. Now the carriage 9 is pushed in the longitudinal direction of the running rail 7 in the direction of the fastening device 11 until the carriage 9, with a contact surface 9a, which is arranged on the side of the carriage 9 facing the fastening device 11, bears against a mating contact surface 11a of the fastening device 11. This condition is in the Fig. 4 shown. By means of fastening means 27a, 27b, which in the embodiment shown in the figures extend in the longitudinal direction of the running rail 7 Stud bolts 27b are formed with sleeve nuts 27a, the carriage 9 can be fastened to the fastening device 11.

The fastening means 27a, 27b are guided in elongated holes 29 in the carriage 9 and penetrate the carriage 9. The long cross section of the elongated holes 29 extends in the vertical direction, as a result of which the fastening means 27a, 27b have freedom of movement in this direction. The elongated holes 29 are formed in an adapter element 31. The adapter element 31 is inserted into the carriage 9 from the side facing the first edge 3b of the door leaf 3 and received in a form-fitting manner.

The stud bolts 27b are fixed to the fastening device 11. The carriage 9 is pushed onto the stud bolts 27b so that the stud bolts 27b extend through the elongated holes 29. On the side of the carriage 9 facing away from the fastening device 11, the sleeve nuts 27a are screwed onto the stud bolts 27b. For this purpose, the sleeve nuts 27a have a receiving opening with an internal thread. In the front area of the receiving opening, the sleeve nuts have a cylindrical bore which then merges into the thread which interacts with the stud bolts 27b. The cylindrical bore has the advantage that the ends of the stud bolts 27b can be guided over it and thus the sleeve nuts 27a can be placed on the stud bolts 27b in an advantageous manner.

The mating contact surface 11a of the fastening device 11 is arranged on a flange projection 32, which engages in a recess 33 of the carriage 9 in the longitudinal direction of the running rail. As a result, the fastening device 11 and the carriage 9 are centered, so that it is ensured that the fastening means 27b can engage in the corresponding holes in the carriage 9. Centering is also carried out on the Fastening device 11 arranged projections 45, which form a gap to the door leaf 3 and engage in the centering projections 26 of the carriage 9. To illustrate the internal structure of the carriage 9 are in Fig. 5 and 6 Individual elements of the carriage 9 are shown in detail, the frame of the carriage 9 being hidden for the purpose of illustration. In Fig. 6 one of the jaws 25 is also not shown.

The drive 5 has a height adjustment, which has an adjusting screw 38. The adjusting screw 38 and the fastening means 27a each have an operating element on the side facing the first side edge 3b, which is designed in the form of a head with an engagement opening for a tool.

The adjusting screw 38 presses against a sloping flank 39 of the fastening device 11 via a ball head 38a. The sloping flank 39 is shown in FIG Fig. 6 shown, in which the front jaw 25 is hidden for the purpose of illustration. A vertical adjustment of carriage 9 and fastening device 11 relative to one another can be achieved in a simple manner via the adjusting screw 38. The sloping flank 39 is formed by sloping surfaces of the clamping jaws 25. In the assembled state, a gap 39a is formed between the inclined surfaces Fig. 3 is indicated. The gap 39a forms a guide for the ball head 38a of the adjusting screw 38. The inclined surfaces are formed by inserts 39b embedded in the clamping jaws 25, which can be made, for example, of stainless steel and are therefore low-wear.

The adjusting screw 38 can have a stop which limits the adjustment path of the adjusting screw 38 and thus prevents the carriage 9 from being pressed away from the fastening device 11 via the adjusting screw.

The adjusting screw 38 extends up to the first side edge 3b of the door leaf 3, which ensures advantageous operation.

The damper unit 12 has an axis 41 which engages in the carriage 9. The damper unit 12 is fastened to the carriage 9 by means of the axis 41. The axis 41 extends into the frame 9b of the carriage. The rollers 19 are arranged on both sides of a roller block 43 which is mounted on the axis 41. As a result, the individual roller stands 43 can execute a pivoting movement relative to the carriage 9.

In the sliding door system 1 according to the invention, the door leaf 3 can also be guided with two drives 5, for example. It is preferably provided that the second drive 5 is arranged mirror-inverted to the first drive 5 and is aligned accordingly to the second side edge opposite the first side edge 3b.

The sliding door system 1 according to the invention can also have a plurality of door leaves 3 which are guided in rails 7 arranged in parallel. With such a configuration, each drive 5 does not necessarily have to have a damper unit 12.

In principle, each drive 5 can have a damper unit 12. For example, in a sliding door system 1 with several door leaves 3, each door leaf 3 can be guided over two drives 5, each drive 5 having a damper unit 12. The damper units 12 of the drives 5 of a door leaf 3 are arranged reversed. The damper units 12 brake the door panels each time they travel to their end position and reliably guide them to the end position. The provision of damper units 12 arranged in the opposite direction and couplers 15 arranged at a corresponding point in the running rail 7 can thus ensure that each door leaf is guided in a braked manner both in its opening and in its closing position. As with sliding door systems with several door leaves 3 these are usually coupled, thus preventing one door wing from braking all the others.

Of course, there is also the possibility that each door leaf has only one damper unit 12 and that, for example, the door leaves are braked and retracted only when they are moving into the closed position.
