Description

The invention relates to a sliding device for a sliding door, possibly a folding sliding door, an arrangement with at least one sliding device, by means of which a sliding door can be displaced within a door compartment, and a drive device.

Sliding doors, optionally folding sliding doors, are often used to close off openings in rooms or pieces of furniture. After the opening has been released, they are moved into a door compartment or into a parking space so as not to be a nuisance.

The US8336972B2 discloses a piece of furniture with a door compartment in which a displacement device is provided, by means of which the sliding door can be displaced within the door compartment. The displacement device comprises a holding device in the form of a pair of scissors, by means of which a stop profile connected to the sliding door is held in a vertical orientation. The displacement device also includes running rails, along which the stop profile is mounted in a displaceable manner by means of drives and can be pushed into the door compartment with practically no resistance.

The US9284761B2 discloses an arrangement, for example a piece of furniture or part of a building, with a displacement device by means of which a folding sliding door can be displaced into a door compartment. The folding sliding door comprises two door elements, of which the first door element is connected at the front to a carriage that can be slid along a running rail that has two rail sections that are aligned perpendicular to one another and are connected to one another by a curved section, one of which is guided into the door compartment. The second door panel is connected to the back with a stop profile, for example, according to the by a holding device US8336972B2 is held vertically.

The WO2020245166A1 discloses a piece of furniture with a door compartment and holding devices shown in the configuration of a scissor cross and a parallelogram system.

In the case of the sliding devices mentioned, the sliding door is manually pushed into the door compartment and manually pulled out of the door compartment again. Shifting devices are also known in which a sliding door, possibly a folding sliding door, can be automatically slid into or out of a door compartment by means of a drive device.

The US7686405B2 discloses a self-closing sliding door assembly having a sliding door counterbalanced by a cable routed over rollers. If the sliding door is moved manually, the counterweight is lifted. After the sliding door has been released, it is returned by the counterweight.

The DE2045763A1 discloses a piece of furniture with a sliding device with a scissors cross whose scissor arms are connected to one another by a spring in order to automatically retract a sliding door held by the scissors cross into a door compartment.

The US8303056B2 discloses a further arrangement with a displacement device, by means of which a stop profile, which is connected to a sliding door by hinges, is held vertically and can be displaced into a door compartment of a piece of furniture. The shifting device comprises two pairs of levers, each with two levers that are firmly connected to one another and pivoted. The first levers of the pairs of levers are connected to the stop profile and the second levers of the pairs of levers are connected to a connecting rod which is always aligned parallel to the stop profile. The pairs of levers are also each connected to a cam, against which a roller presses, which is held by a bearing arm connected to spring elements. The cam is eccentric and has a point of maximum eccentricity. As soon as this maximum eccentricity is overcome by the roller in one direction or the other, the cams and thus the pairs of levers are rotated in one direction or the other under spring force. When retracting, the sliding door is automatically pushed into the end position within the door compartment after overcoming the maximum eccentricity. After overcoming the maximum eccentricity when pulling out the sliding door, it is automatically pushed outwards in front of the door compartment.

The US10227806B2 discloses another displacement device with a control cam, by means of which a sliding door can be displaced from a door compartment.

The US8303056B2 discloses another piece of furniture with a displacement device, by means of which a sliding door connected to a stop profile can be displaced into a door compartment. The stop profile holds a gear wheel which is connected to a torsion spring on the one hand and meshes with a toothed belt on the other hand, which is fastened to a side wall or intermediate wall of the piece of furniture parallel to the running direction of the sliding door. When the sliding door is moved by manual intervention, the torsion spring is tensioned so that the sliding door can move back automatically after release.

The sliding devices described, which support the automatic sliding of a sliding door into a door compartment, require either specially designed holding devices, for example holding devices with lever systems that are to be provided with cams and springs that may need to be attached in the middle of the door compartment and that require a relatively large amount of space take advantage of. The system with a gear wheel driven by a torsion spring requires the time-consuming installation of a toothed belt, which may show signs of wear after a long period of operation. The use of a counterweight for driving sliding doors, on the other hand, has the disadvantage that on the one hand space is required for the counterweight and on the other hand the sliding door can only be displaced as far as the counterweight can be raised within the piece of furniture.

A further disadvantage of some of these devices is that in the event of a malfunction, the entire displacement device or essential parts thereof may have to be dismantled with correspondingly great effort.

The US10724281B2 discloses an arrangement with a door compartment and a displacement device in the form of a running rail, along which a sliding door provided for dividing or closing off a room can be displaced into the door compartment. There are therefore parking spaces or door compartments for sliding doors not only in pieces of furniture, but also in buildings in which sliding doors are moved into a door compartment or parking space after a room opening has been released.

The present invention is therefore based on the object of creating an improved sliding device by means of which a one-piece or multi-piece sliding door, possibly a folding sliding door, can be automatically displaced. Furthermore, an arrangement such as a piece of furniture or a part of a building is to be created with at least one door compartment and with an improved displacement device by means of which a sliding door can be displaced into the door compartment. Furthermore, an improved drive device is to be created, by means of which a sliding door within a door compartment can be automatically displaced over a maximum path length.

The displacement device should be simple in construction and easy to assemble. The displacement device and the drive device should take up little space and allow the sliding door to be displaced over a relatively wide range.

The displacement device should be able to be used in pieces of furniture, cupboards and the like, as well as in building structures that have a door compartment or several door compartments for receiving a sliding door each, optionally a folding sliding door.

Assembly work and any necessary adjustments should be able to be carried out precisely with simple manual intervention. In the event of malfunctions, repair work should be able to be carried out with minimal effort.

It should be possible to dispense with the time-consuming assembly of device parts, such as lever systems and toothed belts, on the side walls of a door compartment. Furthermore, the installation of counterweights should be dispensed with, which take up a relatively large amount of space and can only be used if the door compartment is dimensioned accordingly.

A sliding door or a folding sliding door should be able to be moved powerfully and noiselessly by means of the displacement device of the drive device.

The sliding door should also be able to be operated easily without manual intervention.

This object is achieved with a displacement device according to claim 1, an arrangement with at least one door compartment and an improved displacement device according to claim 12 and a drive device according to claim 15. Advantageous configurations of the invention are specified in further claims.

The displacement device is used to displace a one-part or multi-part sliding door in an arrangement which has wall elements for delimiting a door compartment in which the sliding door can be displaced by means of a drive device.

The displacement device comprises a stop profile, which is connected to the sliding door by stop hinges, which is vertically aligned and slidably held by a holding device, which is preferably connected at an upper end piece to an upper guide carriage which is slidably mounted on an upper guide rail, and which is preferably connected to a lower end piece with a lower guide carriage, which is slidably mounted on a lower guide rail.

According to the invention, the displacement device comprises a first drive device with a first coupling element, via which mechanical energy can be supplied to or removed from the first drive device, and, offset in the displacement direction of the stop profile with respect to the first drive device, a second drive device with a second coupling element, via which the second drive device receives mechanical energy Energy can be supplied or removed, the stop profile or at least one of the guide mechanisms being connected to a first coupling part, which is intended to interact with the first coupling element, and to a second coupling part, which is intended to interact with the second coupling element, and at a displacement of the stop profile, either the first coupling part is coupled to the first coupling element or the second coupling part is coupled to the second coupling part.

The first and the second coupling part are thus directly or indirectly connected to the stop profile. If the first and/or the second guide carriage are provided, the first and/or the second coupling part are preferably connected to one of the guide carriages.

At least one third drive device is preferably provided with a third coupling element, via which mechanical energy can be supplied to or removed from the at least one third drive device and which can be coupled to the first coupling part or the second coupling part or to a third coupling part which is directly or indirectly connected to the stop profile connected is.

The one-part or multi-part sliding door, possibly a folding sliding door, is therefore in operative connection with the first mechanical drive device or the second mechanical drive device within the door compartment. For the following description it is specified that the first or distal drive device is arranged in the rear area of the door compartment and the second or proximal drive device is arranged in the front area of the door compartment. The term "door compartment" includes any limited spaces. The carriages can be provided with rolling elements, sliding elements or magnetic bearings and can carry and/or guide functions.

The first and the second drive device are preferably offset from one another in the displacement direction of the stop profile such that in a transfer position the first coupling part is coupled to the first coupling element and the second coupling part is coupled to the second coupling part. In this transfer position, the sliding door is preferably transferred automatically from the first to the second drive device or from the second to the first drive device.

The first drive device and the second drive device each have a first or second mechanical energy store, which can be charged by shifting the associated first or second coupling element and which returns the associated first or second coupling element when it is discharged.

Elastic elements, such as spring elements, helical springs, tension springs, compression springs, or even magnetic springs or constant force transmitters, can be used as energy stores, which allow the sliding door to be moved. A corresponding constant force transmitter is, for example, in US2004004405A1 described.

The first drive device and the second drive device are charged and discharged by shifting the associated first or second coupling element in the same direction or in opposite directions.

It is preferably provided that both drive devices are designed and arranged in such a way that the sliding door is automatically moved out of the door compartment in the relevant sections in which the drive devices work. The displacement by the two drive devices within the door compartment preferably takes place uninterruptedly between a distal and a proximal end stop.

Preferably, the drive devices each include an integrated locking device, by means of which the associated energy store can be locked after charging, e.g. by compressing or tensioning a spring.

The drive devices can be arranged in such a way that different loading states of the drive devices occur when the stop profile is displaced within the door compartment. Preferably, the drive devices are sequentially unloaded or loaded as the sliding door exits the door compartment. In these cases, there is an automatic ejection from the door compartment or an automatic entry into the door compartment.

It is also possible that the first drive device is loaded or unloaded when the sliding door exits and the second drive device is unloaded or loaded. The arrangement is as desired by the user, the example wise, you want full automatic extension or full automatic retraction or automatic partial travel in the direction of the end stops or to a point between the end stops.

A locking device can be provided at the distal and/or at the proximal end stop, which holds the sliding door in the position it has reached. In the distal end stop, which the sliding door reaches after being pushed into the door compartment, such a locking device can be dispensed with, in particular if the first drive device lying deeper in the door compartment is locked after loading.

Provision is preferably made for this locking to be canceled by pressing on the sliding door. In this case, there is no need for handles by means of which the sliding door is pulled out of the door compartment. Instead, the sliding door is tapped and then automatically moves out of the door compartment. If the extending sliding door is transferred to the charged second drive device, it is fully extended until it stops on the outside of the door compartment.

The first or distal locking device preferably has a self-contained curved track with a locking segment, which is traversed cyclically by a first track element when the first coupling element is actuated, wherein the first track element can be released from the first locking segment by applying pressure to the first coupling element.

The second or proximal locking device preferably has an open curved track with a detent segment, within which a second track element is moved back and forth upon actuation of the second coupling element. The open curved path has a long, straight path segment followed by a short curve serving as a locking segment, into which the second path segment can enter and is held there until it is rotated out of the curve or the locking segment again.

The first drive device preferably comprises a housing and a drive piston which is mounted in a drive channel of the housing in an axially displaceable manner, interacts with the first mechanical energy store and protrudes from the housing.

The first coupling element is preferably a coupling rod with an elongated connecting piece, which is mounted in a bearing channel of the housing so that it can be displaced parallel to the drive piston and which connects a first end piece, which is provided for actuating the drive device and bears on the first coupling part, with a second end piece, which bears on the drive piston. The rod-shaped coupling element makes it possible to mount the first drive device at a desired position inside the door compartment and to interact with the coupling part of the stop profile or the associated drive at another position. The first end piece can therefore lie below, above, to the side of or behind the first drive device, while the second end piece bears against the front of the drive piston.

The upper guide rail is preferably connected to an upper bearing rail which is aligned parallel thereto and in which the first drive device is mounted in a displaceable and fixable manner. The lower guide rail is preferably connected to a lower bearing rail which is aligned parallel thereto and in which the second drive device is mounted in a displaceable and fixable manner. The use of separate bearing rails allows the drive devices to be easily installed and adjusted. The housings of the drive devices and the bearing rails preferably have shaped elements that correspond to one another, such as receiving grooves and corresponding mounting profiles, which engage in one another in a form-fitting manner and allow linear displacement of the drive devices, which are fixed at a suitable point.

The displacement device can be implemented in a particularly space-saving manner if the first drive device is arranged above the upper guide rail and/or the second drive device is arranged below the lower guide rail. The sliding door retracted into the door compartment can therefore advantageously laterally cover the first and/or the second drive device. Therefore, no additional space is required for the drive devices. Instead, the stop profile is guided between the drive devices and is correspondingly reduced in height. If a folding sliding door is provided, the door elements enclose the displacement device with the drive devices in between, with each of the door elements preferably covering the first and/or the second drive device laterally. The displacement device according to the invention, which is equipped with drive devices, therefore requires no more space than a conventional displacement device without drive devices.

The first and the second drive device can be connected in different ways, directly or indirectly, to the displacement device, in particular to the first and/or the second guide rail.

1 shows an arrangement according to the invention in the form of a cabinet 1 in which a door compartment 10 is integrated on both sides, into which sliding doors 11 held by sliding devices 9 according to the invention can be slid. The sliding door assigned to the first door compartment is a folding sliding door which has a first and a second door element 111, 112. In contrast, the one-piece sliding door 11 pushed into the second door compartment 10 has only one door element. The folding sliding door 11 is completely pulled out of the first door compartment 10 and completely unfolded, so that the door elements 111, 112 are aligned in one plane. Two thirds of the cabinet opening 100 are therefore covered by the folding sliding door 11 shown in the closed position.

1 shows further that the arrangement 1 or the cabinet has side walls 12, a top panel 14, a bottom panel 15 and partitions 13, each of which delimits a door compartment 10 with a side wall 12.

Like this too 2 shows, the trailing edge of the first door element 111 when the sliding door 11 is extended is connected by stop hinges 55 to a stop profile 5, which is aligned vertically within the door compartment 10 is movable. The leading edge of the first door panel 111 is connected by door hinges 119 to the trailing edge of the second door panel 112, the leading edge of which is connected to a front running gear 73 at the top. The front drive 73 is guided in a rail 3, the one along the front of the cabinet 1 of 1 has running front section 32 which are connected on both sides by curve sections 33 with door compartment sections 31 which extend into the door compartments 10 .

The metal stop profile 5 is provided with a cross-sectional profile that allows the mentioned hinges 55 and bearing devices 412, 421 and drives 71, 72 to be installed in a simple manner and preferably to be held in a form-fitting manner.

By means of the bearing devices 412, 421, the stop profile 5 is connected to a holding device 4, which keeps the stop profile 5 vertically aligned and displaceable. Holding devices according to the invention displacement devices 9 can be constructed differently. As the WO2020245166A1 disclosed, holding devices can be realized, for example, as scissors crosses or parallelogram systems. Furthermore, the holding device can be a rail system, by means of which the stop profile is held in a displaceable and vertically aligned manner.

The holding device 4 of 2 is a scissor cross with a first scissor arm 41 and a second scissor arm 42 which are rotatably connected to one another by a scissor joint 43 . The ends of the scissor arms 41 , 42 facing the stop profile 5 are connected to the bearing devices 412 , 421 on the stop profile 5 . The ends of the scissor arms 41, 42 that are remote from the stop profile 5 are connected to bearing devices 411, 422 that are stationarily mounted in the cabinet 1. The lower ends of the scissor arms 41, 42 are rotatably, but not slidably, supported by the lower bearing devices 412, 422. The upper ends of the scissor arms 41, 42 are supported by the upper bearing devices 411, 421 in a rotatable and vertically displaceable manner. When the scissors cross 4 is folded or unfolded, the upper ends of the scissor arms 41, 42 can move accordingly, with the stop profile 5 always being held in a vertical orientation.

Furthermore, the upper end piece of the stop profile 5 is connected to an upper guide mechanism 71 which is slidably mounted on an upper guide rail 21 . The lower end piece of the stop profile 5 is connected to a lower guide mechanism 72, which is slidably mounted on a lower guide rail. The guide rails 21, 22 are aligned parallel to one another and perpendicular to the stop profile 5 and are connected, for example, directly or indirectly to the top panel 14, the bottom panel 15, a side wall 12 and/or an intermediate wall 13. When the sliding door 11 is folded, the stop profile 5 can thus be pushed into the door compartment 10 up to a first stop and out of the door compartment 10 again up to a second stop.

According to the invention, a first and a second drive device 6, 8 are provided, which are offset from one another in the displacement direction of the stop profile 5, and by means of which the stop profile 5 and the sliding door 11 connected thereto can be correspondingly displaced.

In the exemplary embodiment of 2 the first drive device 6 is arranged distally, ie closer to the rear of the door compartment 10 in the area of the upper guide rail 21 . The second drive device 8 is arranged proximally, ie closer to the front side or the entrance of the door compartment 10 . The two drive devices 6, 8 are thus assigned different displacement areas, which adjoin one another or overlap one another, so that the sliding door 11 is transferred sequentially from the first to the second drive device 6, 8. The first and second drive devices 6, 8 are both sequentially discharged or both sequentially charged or individually charged and discharged or discharged and charged as desired by the user when sliding the sliding door into or out of the door compartment. That is, the sliding door 11 can be automatically moved out of the door compartment 10 by means of the drive devices 6, 8, automatically moved into the door compartment 10 or automatically moved in or out from a point within the door compartment 10 or from the end positions in the door compartment 10 automatically to a point be moved within the door compartment 10. The automatic displacement out of the door compartment 11 is particularly advantageous. For this purpose, the first drive device is loaded and locked in the distal end position of the sliding door 11 and unlocked by pressing on the sliding door 11, so that the sliding door 11 is accelerated outwards by the first drive device 6 and transferred to the proximal second drive device 8, which controls the sliding door 11 is preferably conveyed to a proximal end position at the entrance of the door compartment 10. In 2 the stop profile 5 has reached this end position.

In preferred configurations, the stop profile 5 is held in the proximal second end position, for example by the second drive device 8, so that the sliding door 11 can be easily folded open and closed again and a stop the sliding door 11 on parts of the cabinet 1 is avoided.

2 also shows damping devices 98 which are mounted inside the door compartment 10, for example on a rear wall, partition wall or side wall of the cabinet 1 and which catch the sliding door 11 in the rear end position. 4a shows a damping element 93, which catches the sliding door 11 in the front end position. Damping devices can also be integrated into the drive devices. Furthermore, spacer rollers 219 are shown, which roll on the sliding door 11 and can keep them at a distance.

3a shows a part of the displacement device 9 of FIG 2 with a view of the entrance of the first door compartment 10, with the first door element 111, which is connected to the trailing edge inside the door compartment 10 with the stop profile 5, and the second door element 112, which is connected to the front drive with the leading edge by a drive hinge 77 73 is connected, which is held within a curved section 33 of the running rail 3. The movements of the trailing edge of the first door element 111 and the leading edge of the second door element 112 when entering and exiting the door compartment 10 are shown with two arrow lines M11, M12.

3b shows the front drive 73 of FIG 3a with a segment of the running rail 3, which has a rail foot 38 and a guide channel 39. The front running gear 73 has a running gear body 730 which holds a roller 731 that has fallen onto the rail foot 38 and two guide rollers 732 guided in the guide channel 39 . In addition, a coupling element or a coupling bolt 733 is mounted in the carriage body 730, by means of which a coupling arm 734 is held and optionally adjustable in height. The linkage arm 734 supports a deck hinge 77 mounted on the leading edge of the second door panel 112. As shown in FIG.

4a shows a part of the displacement device 9 of FIG 2 in a preferred embodiment with the first and second drive device 6 , 8 mounted in the area of the upper guide rail 21 . A bearing rail 216 is arranged above the guide rail 21 and is positively connected to the upper side of the upper guide rail 21 by a rail coupling 2161 . The first drive device 6, which has a first coupling element 61, is arranged inside the bearing rail 216 in such a way that the first coupling element 61 protrudes into the running area (shown in phantom) of a first coupling part 719, which is carried by a carriage arm 718 or by the carriage body of the upper guide carriage 71 is held.

The second drive device 8, which has a second coupling element 81, is arranged on the underside of the upper guide rail 21 in such a way that the second coupling element 81 protrudes into the running area (shown in phantom) of a second coupling part 729X, which is carried by another carriage arm or by the carriage body of the upper guide carriage 71 is held.

The upper guide carriage 71 is supported with running wheels 711 on a running element 211 of the upper guide rail 21 and can be displaced between the drive device 6 at the rear end of the guide rail 21 and a damping element 93 at the front end of the guide rail 21 . The running element 211 guides the first guide carriage along a straight line.

When the upper guide carriage 71 is displaced, the first coupling part 719 is therefore in contact with the first coupling element 61 in a rear or distal displacement area and in contact with the second coupling element 81 in a subsequent front or proximal displacement area 4a the second coupling element 81 is tilted and locked, so that it must first be rotated and unlocked when passing through the second coupling part 729X. As soon as the first drive device 6 is unlocked and the upper guide carriage 71 is moved forward, the second coupling part 729X moves into the second coupling element 81, rotates it counterclockwise into the horizontal position and is caught by the second coupling element 81 and driven by the second drive device 8, which was unlocked by the rotation of the coupling member 81 is pulled forward against the cushioning member 93. Once the upper guide carriage 71 is engaged by the second drive device 8, it is released from the first drive device 6, which is subsequently unloaded. As soon as the upper guide mechanism 71 has reached the damping element 93 and the sliding door 11 has been ejected, the second drive device 8 is also unloaded. The upper guide carriage 71 is preferably held securely in this end position by the second coupling element 81 .

As soon as the sliding door 11 is slid back into the door compartment 10, the second coupling element 81 is returned to the position shown and rotated back in order to lock the second drive device 8 that has been loaded again. Preferably during the process of locking the second drive device 8, the first Kopp device ment part 719 again in contact with the first coupling element 61 and guides it back into the position shown. In this process, the first drive device 6 is loaded and locked. This locking can be released again by pressing the sliding door 11 again, after which the sliding door 11 is moved back again by the unlocked first drive device 6 .

4a FIG. 1 also shows that the displacement device 9 can be provided with further second drive devices. In the first position rail 216 not only the first drive device 6 but also a third drive device 8X is provided, which protrudes into the running area of the first coupling part 719 with a third coupling element 81X. Between the first driving device 6 and the third driving device 8X, the first guide gear 71 is driven by the second driving device 8 . Since the weight of the sliding door 11 is absorbed by the first guide mechanism 71, which also serves as a support mechanism, and the stop profile 5 is held in a vertical orientation by the holding devices 4, the lower guide mechanism 71 can optionally be dispensed with. Likewise, only one lower guide carriage 72 can be provided.

4b shows the displacement device 9 of FIG 4a with the upper guide deck 71 in the same position from the rear. It is now the second coupling part 729X with its running area (shown in phantom) that runs through the tilted second coupling element 81 .

5 FIG. 12 shows the part of the displacement device 9 from FIG 2 after the folding sliding door 11 has been completely pushed in, the first door element 111 of which has been cut open in order to reveal the view of the first drive device 6 on the top of the door compartment 10 and the second drive device 8 on the bottom of the door compartment 10 .

The upper guide carriage 71, the upper guide rail 21, the upper bearing rail 216 and the first drive device 6 are designed and arranged as already with reference to FIG 4a was described. The second drive device 8, on the other hand, is arranged in a lower bearing rail 228, which is positively connected to the lower guide rail 22. A mounting element or a dovetail-shaped mounting profile 2281 is mounted on the lower bearing rail 228 and engages in the housing of the second drive device 8 in a form-fitting manner. The second drive device 8 can therefore be easily displaced axially along the mounting element 2281 and fixed at a suitable point. The second drive device 8 is in the same position as in FIG 4a but rotated 180° upwards. The second coupling element 81 is again in the running area of the second coupling part 729, which is now held by a coupling arm 728 of the lower guide carriage 72.

5 shows that the coupling parts 719, 729, 729X can be attached to the lower and/or the upper guide carriage 21, 22 or also to the upper end piece and/or to the lower end piece of the stop profile 5 according to the configuration of the displacement device 9.

It is shown that the upper guide carriage 71 has a guiding function and a carrying function and the lower guide carriage 72, which engages in a guide channel of the lower guide rail 22 with guide rollers 721, only has a guiding function.

5 FIG. 12 further shows that the upper bearing rail 216 is connected to the running rail 3 and to an upper mounting rail 201. The upper guide rail 216 and the running rail 3 are positively coupled to one another and aligned parallel to one another. The lower bearing rail 228 is connected to a lower mounting rail 202 at the lower side.

When installing the displacement device 9, the mounting rails 201, 202 are preferably mounted first. Then the bearing rails 216, 228 and the guide rails 21, 22 are mounted. Subsequently, the guide carriages 71, 72, which are positively but axially displaceable by mounting flanges 715 (shown only for the upper guide carriage 21) connected to the stop profile 5 are used.

5 shows that the displacement device 9, whose device parts are arranged one above the other, takes up only little space and can be arranged inside the door compartment 10 between the folded door elements 111, 112.

6 shows the displacement device 9 of FIG 5 from the entrance side of the door compartment 10. The rear part of the lower guide rail 22, which has an upwardly open receiving profile, has been partially cut away to show the lower guide carriage 72 with the rollers 721. The upper mounting rail 201 has been cut away to show the first driving device 6. FIG.

7 shows a part of the displacement device 9 of FIG 2 with the upper guide carriage 71, which is attached to the upper end of the stop profile 5 and guided in the upper guide rail 21 and for cooperation with the upper Drive device 6 is provided. It can be seen that the upper guide rail 21 runs parallel to the door compartment section 31 of the running rail 3 .

8a shows the upper guide carriage 71 of the shifting device 9 of FIG 2 or 4 in the end position within the first door compartment 10 resting against the first coupling element 61 of the first drive device 6 and with a tensioned drive spring 63 (shown schematically). It is shown with one hand that by tapping the sliding door 11 or the upper guide carriage 71, the first drive device 6 can be unlocked, so that the upper guide carriage 71 is subsequently ejected and the first drive device 6 is unloaded.

8b shows the upper guide carriage 71 of FIG 8a after relaxation of the drive spring 63 and a partial extension of the upper guide wheel 71 or before tensioning of the drive spring 63 when the upper guide wheel 71 enters the door compartment 10. It is shown that by means of the drive spring 63 a drive piston 62 was ejected which was not acts directly, but indirectly via the first coupling element 61 on the first coupling part. This advantageous embodiment thus allows the upper guide mechanism 71 to pass under the first drive device 6 practically all the way to the rear of the door compartment 10 .

9a shows the first drive device 6, for example, from 8a after dismantling part of the housing 69. The housing 69 comprises a drive channel 60 in which the drive spring 63 and the drive piston 62 and a locking device 64, 65 are arranged and shown schematically. The drive spring 63 is in direct contact with the drive piston 62, which has been pushed into the housing 69 and has tensioned the drive spring 63. In order to hold the drive piston 62 in this position, a locking device 64, 65 is provided, which has a self-contained cam track 64, which is traversed by a first track element 65 cyclically. The track element 65 is coupled to the drive piston 62 and is currently located in a latching segment 641 of the cam track 64, from which the track element 65 cannot automatically escape. The track element 65 is only lifted out of the latching segment 641 and displaced to a side where it can continue to follow the course of the cam track 64 when the drive piston 62 is abutted. After the drive piston 62 has been fully ejected, the track element 65 is located within a turning segment 642, from which it is pushed to the side again when the drive piston 82 is pushed in and can follow the course of the curved track 64 to the latching segment 641 again.

9b shows the part of the housing 69 of 9a and the first coupling element 61 removed therefrom. The first coupling element 61 is designed as a coupling rod and comprises an elongated connecting piece 613 which is mounted in a bearing channel 67 of the housing 69 so that it can be displaced parallel to the drive piston 62 and which is provided for actuating the drive device 6 and which is connected to the first coupling part 719 connects a first end piece 611 that can be contacted or coupled to a second end piece 612 that bears against the drive piston 62 . A running area 66 with a front and a rear end stop is provided in the housing 69 for the first end piece 611 .

10a shows the lower part of the displacement device 9 with the stop profile 5 in the position of 8a with the lower guide carriage 72, which is biased by a driver 81 and locked the second drive device 8 of 5 is still far away. It is shown that the second coupling part 81 can be displaced within a drive channel 80 of the second drive device 8 .

10b shows the lower track deck 72 of FIG 9a , which was caught by the second coupling element 81 of the second drive device 8 and pulled towards the entrance of the door compartment 10 . One shell of housing 89 has been removed to reveal the drive mechanism.

It is shown that the second coupling element 81, which is designed as a driver, is rotatably held in a carriage 82. The carriage 82 is connected to an elastic tension element 83 (shown in phantom), a tension spring or a tension belt, which is guided over a deflection roller 86 and connected to the housing 89 . The carriage 82 can be displaced along an open curved path 84 which has an elongated running segment 842 and a curved locking segment 841 adjoining it.

11 shows that the second drive device 8 also includes a locking device which has the curved latching segment 841 and a track segment 85 which follows the curved track 84 and can then move into the latching segment 841. The carriage 82 holding the locked second coupling member 81 has been removed and shown separately. A dot-dash line shows that the track element 85 is held in the latching segment 841 . The carriage 81 holds a second track element 851 which is still held in the running segment 842 of the cam track 84 . With An arrow symbolically shows the coupling part 729 connected to the stop profile 5 or to one of the guide mechanisms 71, 72, through which the fork-shaped second coupling element 81 can be unlocked by turning it counterclockwise.

The two coupling parts 719A, 719B are connected to the carriage body or carriage arm 718 of the first carriage 71 and are spaced apart from one another in the running direction, if necessary also in height, in such a way that they can be coupled to the first and the second coupling elements 61, 81 at the same time. In 12 1, the first carriage 71 is shown in a transition region, in which the second coupling part 719B releases the second coupling element 81 from the lock and is subsequently pulled away from the second drive device 8. On the return journey, the second coupling element 81 is guided by the second coupling part 719B to the end stop and rotated or locked, with the first coupling element 61 preferably being gripped by the first coupling part 719A and pushed to the end stop at the same time. The cover of the second driving device 8 is partially cut away to reveal the second coupling part 81 . The first drive device 6 can be designed in the same way as the second drive device 8 .

The locking of at least the first drive device 6 can also be triggered by an actuating element which is provided at the entrance of the door compartment 10 .
