Description

[0001] Sliding device with a mounting profile, installation method and

[0002] functional unit

[0003] The invention relates to a sliding device with a mounting profile which, when connected to a single-part or multi-part door, optionally a folding sliding door, is vertically aligned and preferably automatically displaceable within a door compartment, a functional unit, in particular a piece of furniture or a room unit, with at least one sliding device, and a method for installing the sliding device within the functional unit.

[0004] To close off openings in functional units such as furniture, room units, kitchens or sleeping areas, single-part or multi-part doors, sometimes folding sliding doors, are often used. After the opening has been cleared, these doors are pushed into a door compartment of the functional unit so as not to be a disruptive feature.

[0005] US8336972B2 discloses a piece of furniture with a sliding device by means of which a mounting profile connected to a one-piece door can be moved within a door compartment. The sliding device comprises a holding device in the form of a scissor cross, by means of which the mounting profile is held displaceably in a vertical orientation. The sliding device further comprises guide rails along which the mounting profile is displaceably mounted by means of carriages.

[0006] US9284761B2 discloses a piece of furniture with a sliding device by means of which a mounting profile connected to a folding sliding door can be moved within a door compartment. The folding sliding door comprises two door elements, of which the first door element is connected at the rear to the mounting profile by stop hinges and at the front to the rear of the second door element by door hinges. The second door element is connected at the front to a carriage that can be moved along a guide rail having two rail sections aligned perpendicular to each other and connected by a curved section. A first rail section extends into the door compartment, and a second rail section runs along the front of the piece of furniture.

[0007] With the aforementioned sliding devices, the mounting profile is manually inserted into the door compartment with the sliding door and manually withdrawn from the compartment. Sliding devices are also known in which a mounting profile connected to a sliding door can be automatically moved within a door compartment by means of a drive device.

[0008] DE2045763A1 discloses a piece of furniture with a sliding device featuring a scissor-type cross mechanism, whose scissor arms are connected to each other by a spring to automatically retract a mounting profile, held by the scissor-type cross mechanism and connected to a door, into or out of a door compartment. The scissor-type cross mechanism takes up a relatively large amount of space and is typically adapted to the dimensions of the respective door compartment.

[0009] US10227806B2 discloses a further sliding device with a control cam, by means of which a mounting profile connected to a door can be automatically displaced within a door compartment.

[0010] The sliding devices described above feature a drive mechanism for automatically moving the mounting profile. This mechanism either interacts with and is integrated into specially designed holding devices, or acts as a separate drive mechanism that grips the mounting profile near an end stop and pulls it into its final position. These separate drive mechanisms typically require a lot of space and are only capable of moving the mounting profile a short distance. These drive mechanisms are also relatively expensive and only available in predefined sizes.

[0011] The drive devices and the other elements of the sliding devices must therefore be adapted to each other and are thus subject to significant restrictions. It should be noted that there is usually little space within the door compartment, which may be designed to accommodate more than one door element, which is why the restrictions on integrating the drive device into the sliding device are particularly critical.

[0012] EP1394349A1 discloses a sliding device with a displaceably mounted mounting profile, which is held perpendicular to the direction of displacement by means of a holding device with two metal cables. The mounting profile is provided with two lower wheels at the lower end and two upper wheels at the upper end, which are designed to roll on upper and one lower guide rail. The first metal cable is guided clockwise around the associated upper wheel and counterclockwise around the associated lower wheel, and is held and tensioned on both sides by cable connection devices arranged on the front and rear of the sliding device. The second metal cable is guided counterclockwise around the associated upper wheel and clockwise around the associated lower wheel, and is held and tensioned on both sides by cable connection devices arranged on the front and rear of the sliding device.

[0013] US4976502A discloses another holding device with two metal cables by means of which a mounting profile is held displaceably in a vertical orientation.

[0014] The disadvantage of these devices is that the function of the holding device depends significantly on the cable tension adjustment. If the cable tension is not adjusted correctly, the mounting profile may not be held properly or blockages may occur. It should also be noted that the sliding device installations are carried out by different installers at the installation site. This results in different settings, which impair the function of the sliding device and require maintenance.

[0015] In addition, excessive loads can occur in poorly installed sliding devices when forces are applied, which can cause damage and require readjustment.

[0016] Even with optimal adjustment of the shifting device, there is the problem that blockages can occur when forces are applied to the shifting device.

[0017] The present invention is therefore based on the object of creating an improved sliding device by means of which a mounting profile that is connected or connectable to a single-part or multi-part door can be displaced vertically within a door compartment of a functional unit, a piece of furniture, or a room unit. Furthermore, a method for installing the sliding device is to be specified. Furthermore, a functional unit, a piece of furniture, or a room unit is to be created with at least one improved sliding device by means of which a mounting profile connected to a door, optionally a folding sliding door, can be advantageously displaced within a door compartment of the functional unit.

[0018] The sliding device should be compact in design, easy to install and take up little space so that a lot of space can be kept free within the door compartment of the functional unit and the door compartment can be realized with reduced dimensions.

[0019] The sliding device should be easy and precise to adjust so that the sliding device is always optimally adjusted regardless of the respective installer.

[0020] The sliding device should function reliably even under undesirable forces and should not be exposed to loads that could cause damage. The sliding device should be robust and resilient. Maintenance work and readjustment should be largely avoided, even under high stress and strain.

[0021] Preferably, the mounting profile of the sliding device should be automatically movable within the door compartment so that an installed door is automatically retracted into the door compartment or automatically ejected from the door compartment.

[0022] This object is achieved with a sliding device according to claim 1, a method for installing this sliding device according to claim 13, and an improved functional unit according to claim 16, which has at least one door compartment with a sliding device according to claim 1 arranged therein. Advantageous embodiments of the invention are specified in further claims.

[0023] The sliding device, which is intended for installation in a door compartment of a functional unit, comprises a preferably rod-shaped mounting profile, which is held vertically aligned by a holding device and is displaceable between a first end position and a second end position of a travel path and is or can be connected to a one-part or multi-part door by means of stop hinges.

[0024] The holding device comprises a first front-side rope connection device, a first lower roller unit arranged at a lower end of the mounting profile, a first upper roller unit arranged at an upper end of the mounting profile, and a first rear-side rope connection device, as well as a first holding rope which is connected by a first end piece to the first front-side rope connection device, preferably guided counterclockwise around the first lower roller unit and preferably clockwise around the first upper roller unit, and connected by a second end piece to the first rear-side rope connection device;and a second front-side rope connection device, a second upper roller unit arranged at the upper end of the mounting profile, a second lower roller unit arranged at the lower end of the mounting profile, and a second rear-side rope connection device, as well as a second holding rope which is connected by a first end piece to the second front-side rope connection device, preferably guided clockwise around the second upper roller unit and preferably counterclockwise around the second lower roller unit, and connected by a second end piece to the second rear-side rope connection device.;

[0025] According to the invention, the second rear-side cable connection device comprises a second tensioning device with a second connecting slide, which on the one hand is connected to the associated second holding cable and on the other hand is connected by a second tension spring to a second pulling slide, into which a stationary second tensioning screw is screwed, by means of which the second pulling slide and the second connecting slide are displaceable relative to one another within a second bearing profile along the longitudinal axis thereof; wherein the first front-side cable connection device comprises a first adjusting device with a first adjusting slide, which on the one hand is connected to the fixed first holding cable and on the other hand cooperates with a stationary adjusting screw which is rotatably held in the first adjusting slide.

[0026] The two retaining cables of the holding device, for example, steel cables, which may be coated with precious metal and / or plastic, always keep the mounting profile perpendicular to the guide rails during movement within the door compartment. The sliding device can also be implemented with a kinematic reversal or mirroring of device components.

[0027] According to the invention, one of the retaining cables of the holding device is always held elastically, while the other, non-elastic, retaining cable is used to adjust the mounting profile. The elastic retention of the second retaining cable ensures that no blockages occur. Impacts can be absorbed elastically, preventing excessive loads on the sliding device. The sliding device according to the invention can therefore be operated maintenance-free for extended periods. If installed on the front, the adjustment of the adjusting device can be easily performed directly at the entrance to the door compartment.

[0028] By operating the adjusting device, the portion of the first retaining cable that is active in the retaining device is lengthened or shortened, thereby adjusting the inclination of the mounting profile. This adjustment is facilitated by the elastic coupling of the second retaining cable. The first retaining cable prevents the mounting profile from tipping forward toward the exit of the door compartment under the influence of the weight of the installed door.

[0029] The holding device functions optimally when the tensile force is set to a predetermined value, at least in the elastically held holding cable. Preferably, a predetermined tensile force is also set or impressed in the first holding cable. The tensile forces set in the holding cables are preferably identical.

[0030] The tensile force should be neither too low nor too high, to avoid instability on the one hand, and blockages or overloading on the other. By operating the second tensioning device, the tension carriage can be moved relative to the connecting carriage, stretching the tension spring and exerting a tensile force on the second tension cable. By testing the behavior of the displacement device, optimal values ​​for the tensile stress or the mutual displacement of the connecting carriage and the tension carriage, or the extension of the tension spring, can be determined. Therefore, an optimal mutual displacement of the tension carriage and the connecting carriage can always be specified and adjusted for installation of the displacement device.

[0031] In a preferred embodiment, the first rear cable connection device comprises a first tensioning device with a first connecting slide, which is connected on one side to the first retaining cable and on the other side by a first tension spring to a first tension slide, in which a first tensioning screw is axially displaceably held, by means of which the first tension slide and the first connecting slide are displaceable relative to one another within a first bearing profile along its longitudinal axis. Preferably, the first and second tensioning devices have identical device parts.

[0032] In this preferred embodiment, the first and second retaining cables can thus be tensioned with a predetermined tensile force. While the tensile force is still being applied to the first retaining cable, the first connecting carriage is fixed relative to the bearing housing, after which the vertical alignment of the mounting profile is achieved by actuating the adjusting device, as described above. The retaining device therefore always operates with an optimal setting and optimal tensile forces in the retaining cables.

[0033] To set a desired tensile force in the holding cables, a measuring rod is preferably connected to the tension carriage in the tensioning devices. This measuring rod overlaps the connecting carriage and indicates the relative displacement of the tension carriage and the connecting carriage. Alternatively, the measuring rod is connected to the connecting carriage, overlaps the tension carriage, and indicates the relative displacement of the tension carriage and the connecting carriage.

[0034] The measuring rod preferably comprises a control element, such as a control window or a pointer, by means of which the position on the connecting slide or on the pulling slide is indicated, which corresponds to the mutual displacement of the connecting slide and the pulling slide and which can be read off the control element. The connecting slide or the pulling slide overlapped by the measuring rod has a corresponding grid or coloring, which facilitates reading. Markings, such as colors or a scale, are preferably provided. The clamping screw is turned until the control element reaches the mark, which is to be set according to a previously determined recommendation. For example, a table is provided in which the pulling forces to be set for different dimensions and weights of the held door are specified.In order to make the mutual displacement of the connecting slide and the pulling slide visible within the bearing profile, the bearing profile preferably has at least one elongated profile opening.

[0035] The bearing profiles, which preferably have an input roller at their entrance, are preferably aligned perpendicular to the guide rails. This allows a relatively long bearing channel to be provided in the bearing profiles, allowing the connecting carriage and the associated pulling carriage to be adjusted over a long distance as needed.

[0036] The installation of the sliding device described below can be carried out particularly easily if the first front-side rope connection device or the first rear-side rope connection device comprises a clamping device by means of which the facing first or second end piece of the first holding rope can be clamped and held, and / or if the second front-side rope connection device or the second rear-side rope connection device comprises a clamping device by means of which the facing first or second end piece of the second holding rope can be clamped and held. Due to these measures, it is not necessary for the holding ropes to be precisely dimensioned and, for example, provided with connection eyes. Instead, the holding ropes can be inserted manually, tensioned manually, and clamped. Regardless of the dimensions of the sliding device, the installation of the holding ropes can be carried out advantageously.The retaining cables can then be pre-tensioned to a predetermined tensile force, preferably using tension springs. The clamping devices are preferably provided in the form of connecting slides in the rear cable connection devices.

[0037] In a preferred embodiment, the mounting profile is connected at an upper end piece to an upper guide carriage, which has an upper carriage body and is slidably mounted on an upper guide rail; and / or the mounting profile is connected at a lower end piece to a lower guide carriage, which has a lower carriage body and is slidably mounted on a lower guide rail. By using an upper guide carriage and / or a lower guide carriage, forces acting perpendicularly on the mounting profile are absorbed. Therefore, the holding device only absorbs torques acting on the mounting profile.

[0038] Preferably, the first front-side rope connection device is arranged at the front end of the lower guide rail and held by the latter, and / or the first rear-side rope connection device is arranged at the rear end of the upper guide rail and held by the latter, and / or the second front-side rope connection device is arranged at the front end of the upper guide rail and held by the latter, and / or the second rear-side rope connection device is arranged at the rear end of the lower guide rail. This results in simple and stable installation of the rope connection devices. Therefore, only the guide rails need to be connected to a side wall of the functional unit, while practically all other parts of the displacement device, including front-side stop devices, can be connected to the guide rails.

[0039] The optional drive unit is also connected to the mounting profile or one of the guide rails. The sliding device according to the invention can thus be easily installed in any door compartment in any configuration.

[0040] The first lower roller unit and the second lower roller unit are preferably held coaxially aligned with one another by a lower bearing shaft which is connected to the lower carriage body of the lower guide carriage. The first upper roller unit and the second upper roller unit are preferably held coaxially aligned with one another by an upper bearing shaft which is connected to the upper carriage body of the upper guide carriage. It is also possible to connect the bearing shafts to the mounting profile. However, the bearing shafts can be easily integrated into the guide carriages. This also results in a greater distance between the two bearing shafts. The roller units can rotate freely and independently of one another, so that the mounting profile can be moved without friction. This also ensures that the automatic displacement by means of the at least one drive device can take place efficiently.

[0041] The displacement device according to the invention preferably comprises at least one drive device which has a housing in which a drive element and a transmission medium are provided, by means of which a force can be transmitted from the drive element to the mounting profile.

[0042] For example, a so-called damping / retraction device is used, by means of which the mounting profile or a part connected to it is grasped and pulled to an end stop.

[0043] In a preferred embodiment, a drive device is firmly connected to the housing with the mounting profile or one of the guide carriages and is movable together with the mounting profile. The transmission medium of this drive device is preferably a traction cable, which is guided from the drive device directly or via a first deflection pulley or via the first deflection pulley and a second deflection pulley to a traction cable connection, which is arranged stationary at the first or second end position of the travel path or is connected to a part of the functional unit.

[0044] By means of the drive device, the mounting profile can be moved automatically in one direction towards the first end position or in the other direction towards the second end position.

[0045] The drive device or the housing of the drive device is preferably arranged laterally next to the mounting profile or to one of the guide carriages with respect to the displacement axis of the mounting profile or with respect to the travel path of the mounting profile. This arrangement of the drive device prevents a shortening of the travel path. This means that it prevents the housing of the drive device from hitting a stop before one of the guide carriages or the mounting profile hits a stop. The use of the drive device therefore does not restrict the movement of the mounting profile.

[0046] It is particularly advantageous that the drive device is slidably connected to the mounting profile or a guide rail and does not have to be mounted on a part of the functional unit within the door compartment that is difficult to access and may only be accessible after removing a rear or side panel of the functional unit. Maintenance of the sliding device is also simplified. If, for example, the drive device requires maintenance, the mounting profile can simply be pulled toward the front of the door compartment to easily access the drive device.

[0047] The drive device can also be fully or partially integrated into the associated guide drive, so that an even more compact design of the displacement device can be realized.

[0048] In preferred embodiments, it is provided that the drive element is a spring element, a mainspring, such as a helical spring or a spiral spring, and that the traction cable is wound on a traction cable pulley which is rotatably mounted and connected to the drive element, wherein the drive element can be tensioned by rotating the traction cable pulley in one direction and the drive element can be relaxed by rotating the traction cable pulley in the other direction.

[0049] If a first deflection pulley is provided, it is preferably connected directly or indirectly to the mounting profile or to one of the guide rollers. A second deflection pulley, if provided, is also preferably connected directly or indirectly to the mounting profile or to one of the guide rollers. This allows the traction cable to be guided as needed while still maintaining a compact design. The traction cable is guided and deflected close to the mounting profile, thus requiring no additional space.

[0050] Preferably, the first deflection pulley is displaceably mounted relative to the housing of the drive device and relative to the second deflection pulley, whereby a preload can be transmitted to the drive element. The traction cable is preferably guided from the housing of the drive device to the first deflection pulley and preferably at least approximately parallel back to the second deflection pulley.

[0051] The first deflection roller is preferably rotatably supported by a deflection unit, which is held in a form-fitting and / or force-fitting manner and can be locked in place in a guide channel of the mounting profile. This allows the sliding device to be advantageously adjusted, the drive element to be pre-tensioned, and the adjustment to the weight of the single-piece or multi-piece door connected to the mounting profile. The deflection unit is preferably displaceable parallel to the longitudinal axis of the mounting profile and can be fixed in a suitable position with a fixing screw. For example, the body of the deflection unit engages in the guide channel with a form-fitting fit and is clamped therein by means of the fixing screw. Due to the length of the guide channel, which preferably extends over the entire length of the mounting profile, a correspondingly large adjustment range results, which can be covered by moving the deflection unit with a single hand movement.

[0052] The traction cable connection is preferably arranged on a stop device which comprises a stop buffer and which is mounted in the upper or lower guide rail and which forms an end stop for the upper or lower guide carriage.

[0053] Preferably, two drive devices are provided which are firmly connected to the mounting profile or to one of the guide carriages and are displaceable together with the mounting profile, and which each have a traction cable which is guided from the associated drive device directly or via a first deflection pulley or via the first deflection pulley and a second deflection pulley to an associated traction cable connection which is arranged stationary at the first or second end position of the travel path and is connected to this.

[0054] In a further preferred embodiment, the mounting profile is connected to an auxiliary drive having an extendable piston supported by a spring element which rests against a stop device after the mounting profile has moved into the door compartment. The spring element of the auxiliary drive is tensioned as soon as the mounting profile moves towards the first end position within the door compartment. Once the end position is reached, the spring element of the auxiliary drive is loaded and can support the drive device as the mounting profile begins to move towards the second end position. The drive device and the auxiliary drive therefore complement each other perfectly. The auxiliary drive therefore serves to quickly accelerate the door out of the end position over a short distance of 2 cm - 10 cm, while the main drive continues to move the mounting profile over the entire travel path.

[0055] The mounting profile is preferably connected to a cyclically operating locking device comprising an actuating rod and a gripper that interacts with a stationary gripping element and can be cyclically closed and released again by pressure on the actuating rod. A first displacement of the actuating rod, which is supported by a spring, closes the gripper, and a second displacement of the actuating rod opens the gripper again. The actuating rod is preferably arranged coaxially to the center axis of the gripper, so that the actuating rod can be actuated by the gripping element, which is grasped and released by the gripper.

[0056] The locking device preferably comprises a locking body which has a locking groove on one or both sides, into which a locking element engages. The locking groove preferably runs around a central locking part and is designed such that the associated locking element is guided cyclically in the same direction around the locking part as the actuating rod moves, and engages in a locking area and is released again from the locking area with each revolution. When the first end position within the door compartment is reached, the locking device is therefore actuated and held by the gripper. By pressing on the installed door, the actuating rod is moved and the gripper is released again. The door can therefore be locked within the door compartment with one pressure and released again with a further pressure.

[0057] The sliding device according to the invention can be used for any functional units that comprise a lockable space and are generally delimited by walls or partitions. The functional units can comprise spaces delimited by wooden walls and can be furniture, particularly cabinets. However, functional units can also comprise spaces delimited by walls that can be locked by means of single-piece or multi-piece doors, possibly folding sliding doors.

[0058] The retaining device can be easily adjusted to the size of the door compartment and always works optimally with the retaining profile. If a longer mounting profile needs to be moved over a greater distance in a larger door compartment, simply provide longer retaining cables.

[0059] The retaining cables can be routed close to the guide rails and, when changing from the upper to the lower guide rail or from the lower to the upper guide rail, preferably run at a short distance from the mounting profile. During these changes of direction, the retaining cables typically cross approximately in the middle of the mounting profile. The space within the door compartment is practically taken up only by the mounting profile.

[0060] By avoiding the need for a scissor cross, the sliding device according to the invention can be designed compactly. The door compartment can accommodate larger single-piece or multi-piece doors, including folding sliding doors, which are connected to the mounting profile by stop hinges.

[0061] A functional unit can have one or more door compartments. For example, door compartments are provided on both sides of the functional unit, defining the usable space of the functional unit. A door compartment can also have two sliding devices with single-piece or multi-piece doors, possibly folding sliding doors, which can be used to close off a usable space of the functional unit on both sides of the door compartment.

[0086] The leading edge of the first door element 111 is connected by door hinges 132 to the trailing edge of the second door element 112, the leading edge of which is connected at the top to a front carriage 5F. The front carriage 5F is guided in a support rail 150, which has rail elements connected to one another by curved sections, one of which extends into a corresponding door compartment 18 and one of which extends along the front of the piece of furniture 1. When entering the door compartment 18 and when traveling along the front of the piece of furniture 1, the front carriage 5F always moves ahead, with the change of direction occurring within the curved section.

[0087] Fig. 2 shows the sliding device 10 arranged in the first door compartment 18 of the functional unit 1 of Fig. 1 with a holding device 4 according to Fig. 6 or Fig. 7 (shown schematically in Fig. 2), by which the mounting profile 14 is held displaceably in a vertical orientation.

[0088] Optionally, the mounting profile 14, which is held in a vertical orientation by the holding device 4 and which is connected to the folding sliding door 11 by the stop hinges 131, is connected to a drive device 2 and to an auxiliary drive 3.

[0089] The mounting profile 14 is displaceable along a travel path S between a first end position S1 at the rear of the door compartment 18 and a second end position S2 at the front of the door compartment 18.

[0090] As further described below with reference to Fig. 6, the mounting profile 14 is connected at the upper end to an upper guide carriage 5, which is guided in an upper guide rail 15, and at the lower end to a lower guide carriage 6, which is guided in a lower guide rail 16. The upper guide carriage 5 comprises support rollers 591 and guide rollers 592 and, in addition to the guide functions, also has a support function. The lower guide carriage 6 comprises guide rollers 692, which are guided in the lower guide rail 16.

[0091] In Fig. 2, the upper guide carriage 5 and the lower guide carriage 6 rest at the second end position S2 on an upper stop device 7 and on a lower stop device 8, which are explained in more detail below with reference to Fig. 6 and Fig. 8a and Fig. 8b.

[0092] On the rear first end position S1, a stop device 90 with a stop or a stop plate 9 is provided, which limits the travel path S of the mounting profile 14 on the rear side of the door compartment 18.

[0093] The displacement device 10 according to the invention preferably comprises a drive device 2 with a traction cable 22, which is not yet mounted in Fig. 2. By means of this drive device 2, the mounting profile 14 can preferably be displaced over the entire travel path S.

[0094] An even more advantageous movement pattern of the mounting profile 14 can be achieved if a drive device 2 is provided not only at the upper end of the mounting profile 14 or on the upper guide carriage 5, but also at the lower end of the mounting profile 14 or on the lower guide carriage 6, with the same or identical function. A high initial acceleration followed by a smooth movement of the mounting profile 14 is desirable.

[0095] Optionally, an auxiliary drive 3 is provided, by means of which the at least one drive device 2 is supported in the region of the rear first end position S1. As soon as the mounting profile 14 is released from the rear end position S1 or from the stop plate 9, it is additionally accelerated over a relatively short distance by the auxiliary drive 3. The auxiliary drive 3 enables a rapid movement sequence. The mounting profile 14 does not move sluggishly from the end position S1, but is accelerated rapidly.

[0096] Above and below the auxiliary drive 3, damping devices 99 are provided, which have a damping piston 991 which is displaced when it hits the stop plate 9 and dampens the movements of the mounting profile 14 and avoids a disturbing impact.

[0097] Between the two damping devices 99, a cyclically operating locking device 95 is also provided. This locking device comprises an actuating rod 952 and a gripper 951 that can interact with a stationary gripping element 96 and can be cyclically locked and released again by pressure on the actuating rod 952, which is exerted by the gripping element 96 upon reaching the first end position S1 (see Fig. 11). Thus, by manually or motor-driven pressure on the locking device 95, it can be locked and unlocked again by further pressure.

[0098] Fig. 2 further shows a retraction device E, by means of which the mounting profile 14 or one of the guide carriages 5, 6 can be grasped and pulled to the first end position S1. The holding device 4 according to the invention can therefore be used without or optionally in combination with one or more drive devices 2, E.

[0099] Fig. 3 shows a part of the displacement device 10 of Fig. 2 with the upper end piece of the mounting profile 14, which is connected to an upper guide carriage 5 that is displaceably mounted in an upper guide rail 15 and that is connected to a drive device 2. The drive device 2 comprises a drive unit 21 with a housing 210 in which a drive element 211 is provided and a connected traction cable pulley 212, onto which a traction cable 22 is wound, is rotatably mounted. The drive element 211 is preferably a drive spring, such as a spiral spring or a helical spring, which is tensioned or relaxed when the traction cable pulley 212 rotates. The traction cable pulley 212 is rotatably mounted by means of a bearing shaft 215 (shown schematically).The spiral drive element 211 also surrounds the bearing shaft 215 and is firmly connected to the pulley 212 by a first end piece 2111 and to the bearing shaft 215 by a second end piece 2112. When the pulley 212 rotates while the pulley 22 is pulled out, the first end piece 2111 of the drive element 211 is guided around the bearing shaft 215, while the second end piece 2112 of the drive element 211 is held in place. As soon as the pulley 22 is released, the pulley 212 is rotated back again by the tensioned drive element 211. If the coupling element 221 is hooked onto a pull cable connection at the end of the pull cable 22, for example, on the front side, and the mounting profile 14 is retracted into the door compartment 18, the pull cable 22 is pulled out of the drive unit 21, the pull cable pulley 212 is rotated, and the drive element 211 is tensioned.Upon reaching the second end position S2, the mounting profile 14 can now be locked with the locking device 95. As soon as this locking mechanism is released, the pulley 212 is rotated back by the drive element 211, the pulley 22 is retracted, and the mounting profile 14 is moved from the second end position S2 to the first end position S1. A door 11 connected to the mounting profile 14 is therefore automatically extended from the door compartment 18.

[0100] By connecting the drive device 2 to the mounting profile 14 or the guide carriage 5, installation on a rear wall, a partition wall ID, or a side wall 1A of the functional unit 1 is eliminated. A particularly advantageous feature is that the sliding device 10 can be installed in differently sized door compartments 18 without modification. As described below, settings and adjustments can be performed with minimal effort. Even if the sliding device 10 is provided with a drive device 2 on the top side of the mounting profile 14 and a drive device 2 on the bottom side of the mounting profile 14, the installation of the sliding device 10 can be completed with minimal effort.

[0101] Fig. 3 further shows that the mounting profile 14 has two guide channels 141, 142 and a mounting channel 143 in which the stop hinges 131 are held in a form-fitting manner and can be fixed by locking screws 1311.

[0102] At least one of the guide channels 141, 142 serves to hold a deflection unit 230, which can be moved along the mounting profile 14 and fixed at a suitable location by means of locking screws.

[0103] The upper guide carriage 5 comprises a two-part carriage body 51 with a first carriage body part 511 and a second carriage body part 512, which hold vertically aligned support rollers 591 and horizontally aligned guide rollers 592. The two carriage body parts 511, 512 can be connected to one another as one piece, but in this embodiment are connected to one another by a coupling part 55. The support rollers 591 are supported on a running element 151 of the upper guide rail 15, and the guide rollers 592 are guided in a guide channel 152 of the upper guide rail 15. A buffer or damper 58 is inserted into the carriage body 51. Furthermore, the upper guide carriage 5 comprises a stop part 53, which can interact with a buffer or damper on the front stop device 7.

[0104] Fig. 4 shows the upper guide carriage 5 of Fig. 3 from the other side and detached from the mounting profile 14, on which a deflection unit 230 with a first deflection roller 23 is slidably and fixably held. The deflection unit 230 is held in a form-fitting manner in a guide channel 141 or 142 and can be displaced along it and locked at a suitable location. The traction cable 22 of the drive device 2 is guided around the first deflection roller 23 to a second deflection roller 24, which is held by the carriage body 51 of the upper guide carriage. From the second deflection roller 24, the traction cable 22 is guided further to a traction cable connection 72, which is arranged on the upper stop device 7 (see Fig. 5).

[0105] By moving the deflection unit 230 along the mounting profile 14, the path from the pulley 212 to the second pulley 24 can be lengthened or shortened. By extending this path, a corresponding length of the pulley 22 is pulled out of the drive unit 21, the pulley 212 is rotated accordingly, and the drive element 211 is pretensioned accordingly. By pretensioning the drive element 211, it therefore causes it to act on the pulley 22 with a greater tensile force, and the mounting profile 14 is moved with greater force from the first end position S1 toward the second end position S2. This adjustment can be easily performed in just a few simple steps.

[0106] Fig. 4 further shows that the first drive body part 511 has a downwardly directed mounting blade 5111, which can be inserted into a mounting opening 140 of the mounting profile 14. A part of the mounting profile 14 is held between the mounting blade 5111 and a holding plate 5112.

[0107] The first carriage body part 511 also supports a bearing shaft 415, on which a first upper roller unit 411 and a second upper roller unit 412 are rotatably mounted. The first and second roller units 411, 412, which form a pair of rollers 41, are part of the holding device 4, which will be explained below. Resting above the pair of rollers 41 is a functional part 57, which secures the holding cables 421, 422 shown in Fig. 6.

[0108] In the second drive body part 512, a damper channel 5120 is provided, in which a drive damper 58 is arranged and fixed by means of a locking element, optionally a fixing screw 5121.

[0109] Fig. 5 shows the upper part of the displacement device 10 of Fig. 2 with the drive device 2, from which the traction cable 22 is guided via the first deflection roller 23 of the deflection unit 230 slidably connected to the mounting profile 14 and the second deflection roller 24 connected to the upper guide carriage 5 to a traction cable connection 72 on the upper stop device 7, which is held on the front side of the upper guide rail 15.

[0110] To activate the drive device 2, the coupling part 221 is grasped at the end of the traction cable 2, guided around the first and second deflection pulleys 23, 24, and hooked into the traction cable connection 72 of the upper anchor device 7. This process can be completed in just a few simple steps.

[0111] The stop device 7 is held by a mounting beam 711 (see Fig. 8b) in a retaining channel 157 provided on the underside of the running element 151 of the upper guide rail 15. Therefore, above the running element 151, the running technology with the support rollers 591 and the guide rollers 592 of the upper guide carriage 5 (see Fig. 3) is provided, as well as an adjusting part 159 for adjusting the damper engagement depth, which can interact with the carriage damper 58. On the underside of the running element 151, however, the drive technology with the traction cable 22 and the holding technology of the holding device 4 with holding cables 421, 422 are provided (see also Fig. 6).

[0112] Depending on whether a door is provided with one door element 111 or two door elements 111, 112, the stop device 7 comprises one or both sides of a spacer roller 79, on which the held door elements 111, 112 can roll without touching the body 71 of the stop device 7. Furthermore, the upper stop device 7 comprises a cable connection device 74, by means of which one of the holding cables 421 of the holding device 4 is held. In addition, a stop damper or stop buffer 78 is provided, which can interact with the stop part 53 of the upper guide carriage 5 (see Fig. 4).

[0113] Fig. 6 shows the displacement device 10 of Fig. 2 with a holding device 4 according to the invention, which comprises two holding cables 421, 422. The upper guide carriage 5 provided at the upper end of the mounting profile 14 is guided in the upper guide rail 15, and the lower guide carriage 6 provided at the lower end of the mounting profile 14 is guided in a lower guide rail 16. The upper stop device 7 is shown on the front side of the upper guide rail 15, and the lower stop device 8 is shown on the front side of the lower guide rail 16 (see also Fig. 7). The guide rails 15, 16 are not shown in Fig. 6.

[0114] The upper front-side stop device 7 with the mounting beam 711, the pull cable connection 72, and the cable connection device 74 for the second retaining cable 422 has already been explained with reference to Fig. 5. The rotary lever 75 serves to hold the mounting profile 14 in the front-side end position S2. In this position, the mounting profile 14 is held vertically aligned, so that the door 11 or the door elements 111, 112 can be installed particularly easily. The upper cable connection device 74 comprises a mounting channel 741 (see Fig. 8b) with an adjoining recess into which an end piece of the upper retaining cable 422 can be inserted.

[0115] The lower stop device 8 and the upper stop device 7 are described below with reference to Fig. 8a and Fig. 8b. The second pull cable 422 is held in place by the pull cable connection 74 of the upper stop device 7. The pull cable connection 84 of the lower stop device 8, on the other hand, comprises an adjusting slide 842, which is slidably mounted and adjustable by means of an adjusting screw 845. The adjusting screw 845 and the adjusting slide 842 form an adjusting device 840. By actuating the adjusting screw 845, the first retaining cable 421 can be tightened or loosened, and the mounting profile 14 can be aligned vertically.

[0116] The holding device 4 comprises a first front-side cable connection device 84, a first lower roller unit 431 arranged at the lower end of the mounting profile 14, a first upper roller unit 411 arranged at the upper end of the mounting profile 14, and a first rear-side cable connection device 44 arranged at the rear end of the upper guide rail 15, as well as the first holding cable 421, which is connected with a first end piece to the first front-side cable connection device 84, guided counterclockwise around the first lower roller unit 431 and clockwise around the first upper roller unit 411, and connected with a second end piece to the first rear-side cable connection device 44. Furthermore, the holding device 4 comprises a second front-side

[0117] Cable connection device 74, a second upper roller unit 412 which is arranged at the upper end of the mounting profile 14, a second lower roller unit 432 which is arranged at the lower end of the mounting profile 14, and a second rear cable connection device 45 which is arranged at the rear end of the lower guide rail 16, as well as the second holding cable 422 which is connected with a first end piece to the second front cable connection device 74, guided clockwise around the second upper roller unit 412 and counterclockwise around the second lower roller unit 432 and connected with a second end piece to the second rear cable connection device 45.

[0118] In this preferred embodiment, the first front-side cable connection device 84 is provided at the front end of the lower guide rail 16 on the lower stop device 8. The second front-side cable connection device 74 is arranged in this preferred embodiment at the front end of the upper guide rail 15 on the upper stop device 7.

[0119] The second rear cable connection device 45 comprises a second tensioning device 450 with a second tension spring 453, which is connected on the one hand directly or via a second connection slide 452 (shown in dash-dotted lines) to the second holding cable 422 and on the other hand to a second tension slide 454, into which a stationary second tensioning screw 455 is screwed, by means of which the second tension slide 454 can be displaced within a second bearing profile 459 along its longitudinal axis in order to tension the second tension spring 453. During installation, the tension spring 453 is tensioned and a corresponding tensile force is transmitted to the second holding cable 422.

[0120] In the holding device 4 according to the invention, one of the holding cables, in this embodiment the second holding cable 422, is therefore always held elastically. The first holding cable 421, however, is held inflexibly or rigidly after installation by the first front-side cable connection device 84 and the first rear-side cable connection device 44. The vertical alignment of the mounting profile 14 can be achieved by means of the first adjusting device 840, or alternatively at the other end by means of a first adjusting device in the first rear-side cable connection device 44.

[0121] Preferably, the second tension spring 453 is pretensioned or stretched by a predetermined amount. If the second tension spring 453 is connected to the tension carriage 454 on the one hand and to the connecting carriage 452 on the other, the amount of mutual displacement of the tension carriage 454 and the connecting carriage 452 corresponds to the tensile force in the tension spring 453. The applied tensile force can therefore be easily determined based on this displacement. When using a connecting carriage 452, the retaining cable 422 can be connected more easily, as described below.

[0122] With reference to Fig. 7, it is further explained that a tensile force is preferably also applied to the first retaining cable 421 before it is secured. The advantages described above result from applying a tensile force to the second retaining cable 422 or to the first and second retaining cables 421, 422.

[0123] The preferably provided drive device 2, which is held by the upper guide carriage 5, has already been described with reference to Fig. 3. The traction cable 22 of the drive device 2 is guided via the first deflection pulley 23 and the second deflection pulley 24 to the traction cable connection 72, which is provided on the upper front stop device 7. The deflection unit 230 is held in a form-fitting manner by a shaped element 232 in the first guide channel 141 and is displaceable along the mounting profile 14.

[0124] Fig. 7 shows the sliding device 10 of Fig. 6 with the two rear cable connection devices 44, 45 of the holding device 4, each of which has a bearing profile 449, 459 connected to the rear end piece of the upper or lower guide rail 15, 16. The bearing profiles 449, 459 have an elongated bearing opening 4490, 4590 through which the device parts are only partially visible. The device parts provided in the bearing profiles 449, 459, each of which includes a tension spring 443, 453, have therefore been duplicated and shown separately. The tension springs 443, 453 are also shown separately.

[0125] Each of the rope connecting devices 44, 45 comprises an input pulley 441, 451, a connecting slide 442, 452, a tension spring 443, 453, a tension slide 444, 454, a tension screw 445, 455, and a screw holder 446, 456 anchored in the bearing profile 449, 459, by means of which the tension screw 445, 455 is held. The screw holders 446, 456 are each connected to the associated bearing profile 449; 459 by means of a mounting screw 4461. The facing end of the associated retaining cable 421, 422 is guided via the input pulley 441, 451 to the connecting slide 442, 452, which is connected by the tension spring 443, 453 to the pulling slide 444, 454, which in turn is connected by the tension screw 445, 455 to the screw holder 446, 456. By tightening the tension screw 445, 455, the pulling slide 445, 455 is pulled against the screw holder 446, 456 and the tension spring 443, 453 is tensioned.The tensile force exerted by the tension spring 443, 453 is transmitted to the connected retaining cable 421, 422 via the connecting slide 442, 452. The aforementioned parts of the cable connecting devices 44, 45 therefore form tensioning devices 440, 450, by means of which a tensile force in the retaining cables 421, 422 can be adjusted.

[0126] With reference to Fig. 6, it was described that the connecting slide 452 is only optionally provided in the second cable connecting device 45. However, in the first cable connecting device 44 of Fig. 7, which preferably also includes a tensioning device 440, the connecting slide 442 is always present so that the first traction cable 421 can be fixed after the tensile force is applied.

[0127] If the first connecting slide 442 is fixed after adjusting the tensile force in the first retaining cable 421, the set tensile force is subsequently maintained. For this purpose, a fixing screw 448 is provided in the connecting slide 442 of the first rear cable connection device 44. This fixing screw is guided through the profile opening 4490 in the bearing profile 449 and is clamped to the bearing profile 449 when tightened. Therefore, parts of the bearing profile 449 are shown symbolically below the fixing screw 448.

[0128] The installation of the displacement device according to the invention is preferably carried out as follows:

[0129] The mounting profile 14 is aligned vertically and preferably secured. This can be achieved, for example, by means of the locking levers 75, 85 on the stop devices 7 and 8.

[0130] The first holding cable 421 is connected with a first end piece to the first front-side cable connection device 84, guided around the first lower or upper roller unit 431 and around the first upper or lower roller unit 411, and connected with a second end piece to the first rear-side cable connection device 44 and manually tensioned. The first holding cable 421 encircles the roller units 411, 431 once clockwise and once counterclockwise, or vice versa.

[0131] The second holding cable 422 is connected with a first end piece to the second front-side cable connection device 74, guided around the second upper or lower roller unit 412 and around the second lower or upper roller unit 432, and connected with a second end piece to the second rear-side cable connection device 45 and manually tensioned. The second holding cable 421 encircles the roller units 412, 432 once clockwise and once counterclockwise, or vice versa.

[0132] The second holding cable 422 is connected to the second connecting slide 452 in the second rear cable connecting device 45, after which the second tension screw 455 is rotated and the second tension slide 454 and the second connecting slide 452, which are connected to each other by the second tension spring 453, are displaced relative to each other by a predetermined amount.

[0133] The first front-side adjusting slide 842 of the first front-side adjusting device 840 of the first front-side cable connection device 84, which is connected on the one hand to the fixed first holding cable 421, is now adjusted by means of the fixed adjusting screw 845 in order to align the mounting profile 14 vertically or to optimize the vertical alignment of the mounting profile 14, which is previously loosened.

[0134] After completion of the installation process, a predetermined tensile stress is impressed in the second holding cable 422 and the mounting profile 14 is vertically aligned by means of the tensioned first holding cable 421.

[0135] This installation process is optimized by applying a predetermined tensile force to the first retaining cable 421 prior to adjusting or vertically aligning the mounting profile 14. After applying a predetermined tensile force to both retaining cables 421, 422, the effort required to adjust or vertically align the mounting profile 14 is reduced.

[0136] In preferred embodiments of the installation method, the first holding cable 421 in the first rear cable connection device 44 is additionally connected to the first connection slide 442, after which the first tension screw 445 is rotated and the first tension slide 444 and the first connection slide 442, which are connected to each other by the first tension spring 443, are displaced relative to each other by a predetermined amount.

[0137] After this step, the predetermined tensile forces are impressed into both tension cables 421, 422. These adjustments are preferably made while observing the measuring rods, which indicate the degree of mutual displacement of the connecting slides 442, 452 and the tension slides 444, 454, preferably on a scale with markings, possibly color markings.

[0138] After the predetermined tensile stress has been applied, the first connecting slide 442 is fixed to the associated first bearing profile 449. Subsequently, as described, the first front-side adjusting device 840 is actuated to vertically align the no longer fixed mounting profile 14. Typically, only minimal adjustments are necessary.

[0139] Fig. 7 symbolically shows that a second drive device 2' and a second displaceably mounted deflection unit with a first deflection pulley 23' can optionally also be provided on the underside of the mounting profile 14. The lower traction cable would in turn be guided via the first deflection pulley 23' and a deflection pulley, which is fastened, for example, to the lower guide carriage 6, to a traction cable connection 82 on the lower stop device 8. A second drive device 2' and the corresponding device parts can therefore be provided with minimal effort, practically mirroring the first drive device 2.

[0140] Fig. 8a shows the upper stop device 7 and the lower stop device 8 of Fig. 7 in a spatial representation. Fig. 8b shows the upper stop device 7 and the lower stop device 8 of Fig. 7 in a sectional view.

[0141] The upper stop device 7 and the lower stop device 8 each have a device body 71, 81 and a mounting bar 711, 811 formed thereon, which can be locked in the corresponding upper or lower guide rail 15, 16 by means of locking screws 712, 812. The upper stop device 7 has a hook-shaped pull cable connection 72 into which the coupling part 221 of the pull cable 22 can be hooked.

[0142] Furthermore, each stop device 7, 8 preferably has a spacer roller 79, 89 on both sides, which keeps the passing door 11 at a distance, and a rotatable locking lever 75, 85, by means of which the mounting profile 14 can be fixed at the front in order to carry out installation work, maintenance work, or adjustments. If a second drive device 2' is provided, the locking lever 85 could also be used as a pull cable connection 82. The locking levers 75, 85 are held by a holding shell 710, 810, which is connected to the device body 71, 81 by a screw. Furthermore, each stop device 7, 8 has a preferably adjustable stop buffer 78, 88 with a buffer body 781, 881 and an adjusting screw 782, 882.

[0143] The rope connection device 74 of the upper anchor device 7 is of simple design and has a holding block 742 with an upwardly open mounting channel 741 into which an end piece of the second holding rope 422 can be hooked.

[0144] The lower anchor device 8 comprises a cable connection device 84 with an adjusting device 840, which is formed by a displaceable adjusting slide 842 and an adjusting screw 845, by means of which the adjusting slide 842 can be displaced within a bearing profile 843. The adjusting slide 842 has a mounting channel 841 into which the end piece of the first retaining cable 421 can be hooked.

[0145] Furthermore, the lower stop device 8 has a plunger 86 which is axially displaceable by means of an adjusting screw 861 and which can interact with the integrated drive damper 68 of the lower guide drive 6.

[0146] Fig. 9a shows the upper rear rope connection device 44 and Fig. 9b shows the lower rear rope connection device 45, which have already been briefly described with reference to Fig. 7.

[0147] The input roller 441 of the upper rear rope connection device 44 is held by a roller holder 4411, which can be clamped within the bearing profile 449 by means of a tensioning element 4412. The input roller 451 of the lower rear rope connection device 45 is held by a roller holder 4511, which can be clamped within the bearing profile 459 by means of a tensioning element 4512.

[0148] The optional connecting slides 442, 452 have clamping jaws 4421, 4422 and 4521, 4522, respectively, which can be pressed against each other by clamping screws 4423, 4523 to secure the end piece of the respective holding cable 421, 422 inserted between them. The holding cables 421, 422 can therefore be pulled through the connecting slides 442, 452, manually tensioned, and secured.

[0149] Also shown is the fixing screw 448, by means of which the first connecting slide 442 can be fixed to the associated first bearing profile 449. After the first connecting slide 442 is fixed, the first tension spring 443 no longer has any relevant effect. The elasticity of the holding device 4 subsequently determines the still active tension spring 453 of the second cable connecting device 45.

[0150] As mentioned, the aforementioned parts of the cable connection devices 44, 45 form tensioning devices 440, 450, by means of which a tensile force in the holding cables 421, 422 can be adjusted. A measuring rod 447, 457 with an inspection window 4570 is provided for setting a desired tensile force. The measuring rod 457 is connected to the connecting slide 452 and overlaps a scale 4471, 4571 provided on the tension slide 444, 454. The relative displacement of the connecting slide 442, 452 and the tension slide 444, 454, which are slidably mounted in the bearing profile 449, 459, can therefore be read using the measuring rod 447, 457.

[0151] Fig. 10 shows the auxiliary drive 3 from Fig. 2, which is held by the mounting profile 14 and which interacts with a rear end stop 9 after the sliding door 11 has been pushed into the door compartment 18. The auxiliary drive 3 comprises a housing 33 and at least one extendable piston 32, which is supported by a spring element 31 and which rests against the end stop 9 after the mounting profile 14 has moved into the door compartment 18. The spring element 31 of the auxiliary drive 3 is tensioned as soon as the mounting profile 14 moves towards the first end position S1 within the door compartment 18. After reaching the end position, the spring element 31 of the auxiliary drive 3 is loaded and can support the drive device 2 as the mounting profile 14 begins to extend towards the second end position S2.

[0152] The mounting profile 14 is also connected to a cyclically operating locking device 95, which comprises an actuating rod 952 and a gripper 951, which interacts with a stationary gripping element 96 and can be cyclically closed and released again by pressure on the actuating rod 952. A first displacement of the actuating rod 952, which is arranged in a device housing 953 and supported by a spring, closes the gripper 951, and a second displacement of the actuating rod 952 opens the gripper 951 again. The actuating rod 952 is preferably arranged coaxially to the central axis of the gripper 951, so that the actuating rod 952 can be actuated by the gripping element 96, which is gripped and released again by the gripper 951. The gripping element 96 is arranged on the stop plate 9 of the stop device 90, which is fastened to the intermediate wall ID functional unit 1.The displacement path of the actuating rod 952 is indicated by a dot-dash line. Shortly before reaching the end position S1, it strikes the gripping element 96 and is pushed back by it, thereby actuating the gripping device 95 and coupling it to the gripping element 96.

[0153] Furthermore, damping devices 99 with damping pistons 991 are provided, which hit the stop plate 9 as soon as the mounting profile 14 reaches the end position S1.

[0154] The auxiliary drive 3, the gripping device 95 and the damping devices 99 are optional and can be replaced by devices with the same function.

[0155] Fig. 11 shows an assembly configuration of the displacement device 10, which comprises a mounting profile replacement 14', which releasably holds the upper guide carriage 5 and the lower guide carriage 6, an upper guide rail replacement 15', which releasably holds the upper stop device 7 and the first rear cable connection device 44 and is connected to the upper guide carriage 5, a lower guide rail replacement 16', which releasably holds the lower stop device 8 and the second rear cable connection device 45 and is connected to the lower guide carriage 6, and the pre-assembled holding cables 421, 422.

[0156] The holding ropes 421, 422 are connected to the rope connection devices on the front

[0157] 74, 84 of the stop devices 8, 7 and on the back with the

[0158] Rope connection devices 44, 45 connected.

[0159] Fig. 11 also shows one of the partition walls ID from Fig. 1, on which the lower and upper guide rails 15, 16 are already mounted and onto which the sliding device 10, present in the assembled configuration, is transferred. Installation is particularly easy if the partition wall ID is aligned horizontally.

[0160] To install the sliding device 10 in the assembly configuration, it is therefore only necessary to replace the mounting profile replacement 14' with the mounting profile 14 and the upper and lower guide rail replacements 15', 16' with the upper and lower guide rails 15, 16. Subsequently, the described measures for tensioning the retaining cables 421, 422 and for aligning the mounting profile 14 can be carried out.

[0161] The assembly configuration of the displacement device 10 can therefore advantageously be created by the manufacturer, while the installation of the displacement device 10 at the installation site can be carried out by the user almost without instructions in a simple manner, for example with the installation steps described below.

[0162] Preferably, in a first installation step, the

[0163] Mounting profile replacement 14' replaced by mounting profile 14.

[0164] In a second installation step, the guide runners 5, 6, which are now connected to the mounting profile 14, are inserted into the corresponding upper or lower guide rail 15, 16 connected to the partition wall ID.

[0165] In a third installation step, the stop devices 7, 8 are detached from the upper and lower guide rail replacements 15', 16' and inserted into the upper and lower guide rails 15, 16. For this purpose, the mounting bar 711 of the upper stop device 7 is inserted into the mounting channel 153 of the upper guide rail 5, and the mounting bar 811 of the lower stop device 8 is inserted into the mounting channel 163 of the lower guide rail 16.

[0166] In a fourth installation step, the rear cable connection devices 44, 45 are detached from the upper and lower guide rail replacements 15', 16' and connected to the upper and lower guide rails 15, 16. For this purpose, a mounting bar 4495 of the first rear cable connection device 44 is screwed to a mounting connection 154 of the upper guide rail 15. The second rear cable connection device 45 is inserted into the mounting channel 163 of the lower guide rail 16 with a mounting bar 45111, which is connected to the associated roller holder 4511.

[0167] In a final installation step, the upper guide rail replacement 15' is detached from the upper guide carriage 5 and the lower guide rail replacement 16' is detached from the lower guide carriage 6.

[0168] After these installation steps, which are also interchangeable, the sliding device 10 according to the invention is connected solely to the upper and lower guide rails 15, 16.

[0169] Subsequently, the holding cables 421, 422 are tensioned, as already described. List of reference symbols:
