Description

[0001] The invention relates to a sliding device with a mounting profile which, connected to a one-piece or multi-piece door, optionally a folding sliding door, is vertically aligned and preferably automatically slidable 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.

[0002] To close off openings of functional units, such as pieces of furniture, room units, kitchens or sleeping areas, one-piece or multi-piece doors, possibly folding sliding doors, are often used, which are moved into a door compartment of the functional unit after the opening has been released, so as not to be obtrusive.

[0003] US patent 8336972B2 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 recess. The sliding device comprises a holding device in the form of a scissor mechanism by means of which the mounting profile is held so as to be moved vertically. The sliding device further comprises guide rails along which the mounting profile is slidably mounted by means of carriages.

[0004] 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, the first of which 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 track that is movable along a running rail. The running rail has two track sections perpendicular to each other and connected by a curved section. The first track section extends into the door compartment, and the second track section extends along the front of the furniture.

[0005] In the aforementioned sliding devices, the mounting profile is manually inserted into the door compartment along with the sliding door and manually pulled out again. 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.

[0006] German patent DE 2045763A1 discloses a piece of furniture with a sliding device comprising a scissor mechanism, the arms of which are connected to each other by a spring, in order to automatically retract or eject a mounting profile held by the scissor mechanism and connected to a door into a door compartment. The scissor mechanism occupies a relatively large amount of space and is typically adapted to the dimensions of the respective door compartment.

[0007] US10227806B2 discloses a further sliding device with a control cam by means of which a mounting profile connected to a door can be automatically moved within a door compartment.

[0008] The sliding devices described above feature a drive unit for automatically moving the mounting profile. This drive unit either interacts with and is integrated into specially designed holding devices, or, as a separate drive unit, engages the mounting profile near an end stop and pulls it into the end positions. The separate drive units typically require considerable space and are only capable of advancing the mounting profile over a short distance. Furthermore, these drive units are relatively expensive and only available in predefined sizes.

[0009] The drive units and other elements of the sliding mechanism must therefore be adapted to one another 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, making the restrictions on integrating the drive unit into the sliding mechanism particularly critical.

[0010] EP1394349A1 discloses a sliding device with a slidably mounted mounting profile, which is held by a holding device with two metal cables perpendicular to the direction of movement. The mounting profile is provided at its lower end with two lower wheels and at its upper end with two upper wheels, which are designed to roll on an upper and a 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 at both ends by means of 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 at both ends by means of cable connection devices arranged on the front and rear of the sliding device.

[0011] US4976502A discloses a further holding device with two metal cables by means of which a mounting profile is held slidably in a vertical orientation.

[0012] A disadvantage of these devices is that the function of the holding device depends significantly on the cable tension setting. If the cable tension is not correctly adjusted, the mounting profile may not be held properly, or blockages may occur. Furthermore, it should be noted that the installation of the sliding device at the installation site is carried out by different installers. This results in different settings each time, which impairs the function of the sliding device and necessitates maintenance.

[0013] Furthermore, excessive loads can occur in suboptimally installed sliding devices when forces are applied, which can cause damage and require readjustments.

[0014] Even with optimal adjustment of the sliding device, the problem remains that blockages can occur when forces are applied to the sliding device.

[0015] The present invention is therefore based on the objective of providing an improved sliding device by means of which a mounting profile, which is connected or connectable to a one-piece or multi-piece door, can be moved 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 provided. Additionally, a functional unit, a piece of furniture, or a room unit is to be provided 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 moved within a door compartment of the functional unit.

[0016] The sliding device should be compact in design, easy to assemble, and take up little space, so that plenty of space can be kept free within the door compartment of the functional unit and the door compartment can be realized with reduced dimensions.

[0017] The sliding device should be easy and precise to adjust, so that the sliding device is always optimally adjusted regardless of the installer.

[0018] The sliding mechanism should function reliably even under unwanted forces and should not be subjected to stresses that could cause damage. The sliding mechanism should be robust and durable. Maintenance and readjustments should be largely avoided, even under high stress and loads.

[0019] Preferably, the mounting profile of the sliding device should be automatically movable within the door compartment, so that a mounted door is automatically moved into the door compartment or automatically pushed out of the door compartment.

[0020] This problem is solved by 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 arranged therein according to claim 1. Advantageous embodiments of the invention are specified in further claims.

[0021] 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, is slidable between a first end position and a second end position of a travel path and is connected or connectable to a one-piece or multi-piece door by means of stop hinges.

[0022] The holding device includes a first front-facing 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-facing rope connection device, as well as a first retaining rope connected to the first front-facing rope connection device at a first end piece, preferably guided counterclockwise around the first lower roller unit and preferably clockwise around the first upper roller unit, and connected to the first rear-facing rope connection device at a second end piece;and a second front-facing 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-facing rope connection device, as well as a second retaining rope connected at a first end piece to the second front-facing rope connection device, preferably guided clockwise around the second upper roller unit and preferably counterclockwise around the second lower roller unit, and connected at a second end piece to the second rear-facing rope connection device.

[0023] According to the invention, the second rear rope connection device comprises a second tensioning device with a second connection slide, which is connected on one side to the associated second retaining rope and on the other side by a second tension spring to a second tension slide, into which a stationary second tensioning screw is screwed, by means of which the second tension slide and the second connection slide are displaceable relative to each other within a second bearing profile along its longitudinal axis; wherein the first front rope connection device comprises a first adjusting device with a first adjusting slide, which is connected on one side to the fixed first retaining rope and which on the other side interacts with a stationary adjusting screw that is rotatably held in the first adjusting slide.

[0024] The two retaining cables of the holding device, for example, steel cables possibly coated with precious metal and / or plastic, keep the mounting profile perpendicular to the guide rails at all times during its movement within the door compartment. The sliding device can also be implemented with a kinematic reversal or mirroring of device components.

[0025] According to the invention, one of the retaining cables of the holding device is always held elastically, while the other retaining cable, which is not held elastically, is used to adjust the mounting profile. Holding the second retaining cable elastically ensures that no blockages occur. Impacts can be absorbed elastically, so that no excessive stress is placed on the sliding device. The sliding device according to the invention can therefore be operated maintenance-free for extended periods. If the adjusting device is installed on the front, it can be easily adjusted directly at the door opening.

[0026] Actuating the adjusting device lengthens or shortens the portion of the first retaining cable that is effective within the holding device, 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 towards the door opening under the weight of the installed door.

[0027] The holding device functions optimally when the tensile force in at least the elastically held retaining cable is set to a predetermined value. Preferably, a predetermined tensile force is also set or imprinted in the first retaining cable. The tensile forces set in the retaining cables are preferably identical.

[0028] The tensile force should be neither too low nor too high to avoid instabilities, blockages, or overloads. Actuating the second tensioning device allows the pull slide to be moved relative to the connecting slide, thereby stretching the tension spring and exerting a tensile force on the second pull cable. By testing the behavior of the shifting device, optimal values ​​for the tensile tension, the relative displacement of the connecting and pull slides, and the extension of the tension spring can be determined. Therefore, an optimal relative displacement of the pull slide and the connecting slide can always be specified and set for the installation of the shifting device.

[0029] In a preferred embodiment, the first rear-facing cable connection device comprises a first tensioning device with a first connection 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 displaceable, by means of which the first tension slide and the first connection slide are displaceable relative to each other within a first bearing profile along its longitudinal axis. Preferably, the first and the second tensioning devices have identical device components.

[0030] In this preferred embodiment, the first and second retaining cables can be tensioned with a predetermined tensile force. After the tensile force is applied to the first retaining cable, the first connecting slide is fixed relative to the bearing housing, whereupon the vertical alignment of the mounting profile is achieved by actuating the adjusting device, as described above. The holding device therefore always operates with an optimal setting and optimal tensile forces in the retaining cables.

[0031] To set a desired tensile force in the retaining cables, a measuring rod is preferably connected to the pulling carriage in the pulling devices. This rod overlaps the connecting carriage and indicates the relative displacement of the pulling carriage and the connecting carriage. Alternatively, the measuring rod is connected to the connecting carriage, overlaps the pulling carriage, and indicates the relative displacement of the pulling carriage and the connecting carriage.

[0032] The measuring rod preferably includes a control element, such as a viewing window or a pointer, which indicates the position on the connecting slide or the pull slide that corresponds to the relative displacement of the connecting slide and the pull slide and can be read from the control element. The connecting slide or the pull slide overlapped by the measuring rod has a corresponding grid or coloring to facilitate reading. Preferably, markings such as colors or a scale are provided. The clamping screw is turned until the control element reaches the mark that is to be set according to a previously determined recommendation. For example, a table is provided that specifies the tension forces to be set for different dimensions and weights of the held door.In order to make the mutual displacement of the connecting slide and the pull slide within the bearing profile visible, the bearing profile preferably has at least one elongated profile opening.

[0033] The bearing profiles, at the entrance of which an entry roller is preferably provided, are preferably aligned perpendicular to the guide rails. In this way, a relatively long bearing channel can be provided in the bearing profiles, which allows the connecting carriage and the associated pull carriage to be adjusted over a large distance as required.

[0034] The installation of the sliding device described below can be carried out particularly easily if the first front-facing rope connection device or the first rear-facing rope connection device includes a clamping device by means of which the facing first or second end of the first retaining rope can be clamped and held, and / or if the second front-facing rope connection device or the second rear-facing rope connection device includes a clamping device by means of which the facing first or second end of the second retaining rope can be clamped and held. Because of these measures, it is not necessary for the retaining ropes to be precisely dimensioned and, for example, fitted with connecting lugs. Instead, the retaining ropes can be inserted manually, tensioned manually, and clamped. Regardless of the dimensions of the sliding device, the installation of the retaining ropes can be carried out advantageously.The retaining cables can then preferably be pre-tensioned to a predetermined tensile force using the tension springs. Preferably, the clamping devices are provided in the form of connecting slides in the rear cable connection devices.

[0035] 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 perpendicular to the mounting profile are absorbed. Therefore, the holding device only needs to absorb torques acting on the mounting profile.

[0036] Preferably, the first front-facing cable connection device is arranged at the front end of the lower guide rail and held by it, and / or the first rear-facing cable connection device is arranged at the rear end of the upper guide rail and held by it, and / or the second front-facing cable connection device is arranged at the front end of the upper guide rail and held by it, and / or the second rear-facing cable connection device is arranged at the rear end of the lower guide rail. This results in simple and stable mounting of the cable connection devices. Therefore, only the guide rails need to be connected to a side wall of the functional unit, while virtually all other parts of the sliding device, including front-facing stop devices, can be connected to the guide rails.

[0037] The optional drive unit is also connected to the mounting profile or one of the guide carriages. The sliding device according to the invention can therefore be installed particularly easily in any door compartment in any configuration.

[0038] The first and second lower roller units are preferably held coaxially by a lower bearing shaft connected to the lower running gear body of the lower guide carriage. The first and second upper roller units are preferably held coaxially by an upper bearing shaft connected to the upper running gear body of the upper guide carriage. Alternatively, the bearing shafts can be connected to the mounting profile. However, the bearing shafts can also be easily integrated into the guide carriages. This results in a greater distance between the two bearing shafts. The roller units can rotate freely and independently of each other, allowing for frictionless movement of the mounting profile. This also ensures efficient automatic movement by means of the at least one drive device.

[0039] The sliding 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.

[0040] For example, a so-called damping / pulling device is used, by means of which the mounting profile or a part connected to it is gripped and pulled to an end stop.

[0041] In a preferred embodiment, a drive device is rigidly 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 pull 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 pull cable connection that is stationary at the first or second end position of the travel path or connected to a part of the functional unit.

[0042] The drive device allows the mounting profile to be moved automatically in one direction towards the first end position or in the other direction towards the second end position.

[0043] The drive unit, or its housing, is preferably positioned laterally to the mounting profile or to one of the guide carriages, relative to the mounting profile's axis of movement or its travel path. This arrangement of the drive unit prevents a reduction in the travel path. In other words, it prevents the drive unit housing from encountering a stop before one of the guide carriages or the mounting profile itself encounters a stop. Therefore, the use of the drive unit does not restrict the mounting profile's movement.

[0044] It is particularly advantageous that the drive unit 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 inside the door compartment that is difficult to access and may only be accessible after removing a back or side panel of the functional unit. Maintenance of the sliding mechanism is also simplified. For example, if the drive unit needs servicing, the mounting profile simply needs to be pulled towards the front of the door compartment to provide easy access to the drive unit.

[0045] The drive device can also be fully or partially integrated into the associated guide carriage, allowing for an even more compact design of the sliding device.

[0046] In preferred embodiments, the drive element is a spring element, a driving spring, such as a helical spring or a spiral spring, and the pull rope is wound onto a pull rope pulley which is rotatably mounted and connected to the drive element, wherein the drive element can be tensioned by rotating the pull rope pulley in one direction and the drive element can be relaxed by rotating the pull rope pulley in the other direction.

[0047] If a first deflection pulley is provided, it is preferably connected directly or indirectly to the mounting profile or to one of the guide carriages. A second deflection pulley, if provided, is also preferably connected directly or indirectly to the mounting profile or to one of the guide carriages. In this way, the pull cable can be guided as needed, and the sliding device can still be designed compactly. The pull cable is guided and deflected close to the mounting profile, which is why no additional space is required.

[0048] Preferably, the first deflection roller is slidably mounted with respect to the housing of the drive device and with respect to the second deflection roller, thereby allowing a preload to be transferred to the drive element.

[0049] The pull rope is preferably guided from the housing of the drive device to the first deflection pulley and preferably back to the second deflection pulley at least approximately parallel.

[0050] The first deflection pulley is preferably rotatably mounted by a deflection unit, which is slidably and lockably held in a guide channel of the mounting profile by a positive-locking and / or non-positive-locking mechanism. This allows the sliding device to be advantageously adjusted, the drive element to be pre-tensioned, and adapted to the weight of the one-piece or multi-piece door connected to the mounting profile. The deflection unit is preferably slidable 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 positively in the guide channel and is clamped in place 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 traversed with a single hand movement by shifting the deflection unit.

[0051] The pull rope connection is preferably arranged on a stop device which includes 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.

[0052] Preferably, two drive devices are provided, which are rigidly connected to the mounting profile or to one of the guide carriages and are movable together with the mounting profile, and which each have a pull rope 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 pull rope connection, which is stationary at the first or second end position of the travel path, and is connected to it.

[0053] In a further preferred embodiment, the mounting profile is connected to an auxiliary drive which has an extendable piston supported by a spring element. After the mounting profile enters the door compartment, the piston rests against a stop device. 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 assist the drive unit at the beginning of the mounting profile's extension towards the second end position. The drive unit and the auxiliary drive thus complement each other perfectly. The auxiliary drive therefore serves to rapidly accelerate the door from the end position over a short distance of 2 cm to 10 cm, while the main drive continues to move the mounting profile along its entire travel path.

[0054] 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 locked and unlocked by pressing the actuating rod. A first movement of the spring-supported actuating rod closes the gripper, and a second movement of the actuating rod opens the gripper. The actuating rod is preferably arranged coaxially with the central axis of the gripper so that the gripping element can actuate the actuating rod, which is then grasped and released by the gripper.

[0055] Preferably, the locking device comprises a locking body with a locking groove on one or both sides, into which a locking element engages. The locking groove preferably surrounds a central locking part and is designed such that, when the actuating rod moves, the corresponding locking element is guided cyclically around the locking part in the same direction, engaging and disengaging from a detent area once with each revolution. Upon reaching the first end position within the door recess, the locking device is actuated and held by the gripper. Pressing on the installed door moves the actuating rod and releases the gripper. The door can therefore be locked within the door recess by pressing the rod and unlocked by pressing the rod again.

[0056] The sliding device according to the invention can be used for any functional units that comprise a lockable space and are generally bounded by walls or partitions. The functional units can have spaces bounded by wooden walls and may consist of furniture, in particular cabinets. Alternatively, functional units can also have spaces bounded by walls that can be locked by means of one-piece or multi-piece doors, optionally folding sliding doors.

[0057] The mounting device can be easily adjusted to the size of the door compartment and always works optimally with the mounting profile. If a longer mounting profile needs to be moved over a greater distance in a larger door compartment, longer mounting cables are simply required.

[0058] The retaining cables can be routed close to the guide rails and, when changing from the upper to the lower guide rail or vice versa, 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 recess is thus occupied almost entirely by the mounting profile.

[0059] By avoiding a scissor mechanism, the sliding device according to the invention can be designed compactly. The door compartment can accommodate larger one-piece or multi-piece doors, optionally folding sliding doors, which are connected to the mounting profile by stop hinges.

[0060] A functional unit can have one or more door compartments. For example, door compartments may be provided on both sides of the functional unit, defining its usable space. A door compartment may also have two sliding mechanisms with one-piece or multi-piece doors, possibly folding sliding doors, by means of which a usable space of the functional unit can be closed off on both sides of the door compartment.

[0061] The invention is explained in more detail below with reference to the drawings. These show: Fig. 1 shows a functional unit 1 according to the invention in the configuration of a piece of furniture with a first door compartment 18 in which a mounting profile 14 of a sliding device 10 according to the invention, which is connected to a folding sliding door 11, is slidably held by means of a holding device 4, and a second door compartment 18 in which a further mounting profile 14 of a sliding device 10 according to the invention, which is connected to a one-piece door 11, is held by means of a holding device 4 (see Fig. 1).

[0062] Fig. 1 Figure 1 shows a functional unit or piece of furniture 1 according to the invention, in the form of a cabinet in which a door compartment 18 is integrated on each side. The piece of furniture 1 comprises side walls 1A, a top panel 1B, a bottom panel 1C, and partition walls 1D, each of which, together with an associated side wall 1A, defines a door compartment 18. A sliding device 10 according to the invention, with a mounting profile 14, is arranged in each door compartment 18. In preferred embodiments, the mounting profile 14 is automatically slidable within the door compartment 18. Doors 11 are held by the mounting profile 14, which are retracted into or extended from the corresponding door compartment 18 when the mounting profile 14 is moved.

[0063] The first door compartment 18 holds a folding sliding door 11, which has a first and a second door element 111, 112 that are hinged together. The door 11 held within the second door compartment 18 by a mounting profile 14, however, has only one door element 111.

[0064] The folding sliding door 11 is fully extended from the first door compartment 10 and fully unfolded, so that the door elements 111, 112 are aligned in one plane. The door elements 111, 112 of the folding sliding door 11 and the door element 111 of the one-piece door 11 are the same size, which is why the folding sliding door 11, shown in the closed position, covers two-thirds of the cabinet opening 100.

[0065] The trailing edge of the first door element 111 is connected by stop hinges 131 to the mounting profile 14 shown symbolically, which is held at the exit of the door compartment 18 after the folding sliding door 11 has exited.

[0066] The leading edge of the first door element 111 is connected to the trailing edge of the second door element 112 by door hinges 132. The leading edge of the second door element 112 is connected at the top to a front track 5F. The front track 5F is guided in a support rail 150, which has track sections connected by curved segments. One of these sections runs into a corresponding door compartment 18, and the other runs along the front of the furniture piece 1. When entering the door compartment 18 and when running along the front of the furniture piece 1, the front track 5F always runs in the lead, with the change of direction occurring within the curved segment.

[0067] Fig. 2 shows the functional unit 18 in the first door compartment of Fig. 1 arranged sliding device 10 with a holding device 4 according to Fig. 6 or Fig. 7 (in Fig. 2 (shown schematically), from which the mounting profile 14 is held slidably in a vertical orientation.

[0068] 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.

[0069] The mounting profile 14 is movable 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.

[0070] As explained below with reference to Fig. 6 As further described, the mounting profile 14 is connected at its upper end to an upper guide carriage 5, which is guided in an upper guide rail 15, and at its 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 its guiding functions, also has a load-bearing function. The lower guide carriage 6 comprises guide rollers 692, which are guided in the lower guide rail 16.

[0071] The upper guide drive 5 and the lower guide drive 6 are located in Fig. 2 at the second end position S2 on an upper stop device 7 and on a lower stop device 8, which are referred to below. Fig. 6 and Fig. 8a und Fig. 8b will be explained in more detail.

[0072] At 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 of the door compartment 18.

[0073] The inventive sliding device 10 preferably comprises a drive device 2 with a pull rope 22 which is in Fig. 2 not yet mounted. By means of this drive device 2, the mounting profile 14 is preferably movable over the entire travel path S.

[0074] 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 a functionally identical or equivalent drive device 2. A high initial acceleration followed by a smooth movement of the mounting profile 14 is desirable.

[0075] An auxiliary drive 3 is optionally provided, by means of which at least one drive device 2 is supported in the area 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 rapidly accelerated.

[0076] 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 disruptive impact.

[0077] Between the two damping devices 99, a cyclically operating locking device 95 is also provided, which comprises an actuating rod 952 and a gripper 951, which can interact with a stationary gripping element 96 and which can be cyclically locked and unlocked by pressure on the actuating rod 952, which is exerted by the gripping element 96 when the first end position S1 is reached (see Fig. 11 ). By applying pressure manually or by motor to the locking device 95, it can be locked and unlocked again by applying further pressure.

[0078] Fig. 2 Figure 1 further shows a retraction device E by means of which the mounting profile 14 or one of the guide carriages 5, 6 can be gripped 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.

[0079] Fig. 3 shows part of the sliding device 10 of Fig. 2 with the upper end piece of the mounting profile 14, which is connected to an upper guide carriage 5, which is slidably mounted in an upper guide rail 15 and which 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 pulley 212 connected thereto, onto which a pull rope 22 is wound, is rotatably held. The drive element 211 is preferably a spring, such as a spiral spring or a helical spring, which is tensioned or relaxed when the pulley 212 is rotated. The 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 rigidly connected to the pulley 212 at a first end piece 2111 and to the bearing shaft 215 at a second end piece 2112.When the pull rope 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 pull rope 22 is released, the pull rope pulley 212 is rotated back by the tensioned drive element 211. If, for example, the coupling element 221 at the end of the pull rope 22 is hooked onto a pull rope connection at the front and the mounting profile 14 is inserted into the door compartment 18, the pull rope 22 is pulled out of the drive unit 21, the pull rope pulley 212 is rotated, and the drive element 211 is tensioned. The mounting profile 14 can then be locked with the locking device 95 when the second end position S2 is reached.As soon as this locking mechanism is released, the pulley 212 is reversed by the drive element 211, the pull rope 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.

[0080] By connecting the drive unit 2 to the mounting profile 14 or the guide rail 5, mounting on a rear wall, a partition 1D, or a side wall 1A of the functional unit 1 is no longer necessary. A particular advantage is that the sliding device 10 can be installed in door compartments 18 of different dimensions without modification. As described below, adjustments and modifications can be carried out with minimal effort. Even if the sliding device 10 is equipped with a drive unit 2 on the top of the mounting profile 14 and another drive unit 2 on the underside of the mounting profile 14, the installation of the sliding device 10 can be completed with minimal effort.

[0081] 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.

[0082] 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 in a suitable position by means of locking screws.

[0083] 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 supports vertically oriented support rollers 591 and horizontally oriented guide rollers 592. The two carriage body parts 511 and 512 can be integrally joined, but in this embodiment they are connected by a coupling element 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 integrated into the carriage body 51. Furthermore, the upper guide carriage 5 comprises a stop element 53, which can interact with a buffer or damper on the front-facing stop device 7.

[0084] Fig. 4 The upper guide drive 5 shows Fig. 3 from the other side and detached from the mounting profile 14, on which a deflection unit 230 with a first deflection pulley 23 is slidably and lockably held. The deflection unit 230 is positively locked in a guide channel 141 or 142 and is slidable along this channel and lockable at a suitable position. The pull cable 22 of the drive device 2 is guided around the first deflection pulley 23 to a second deflection pulley 24, which is held by the running gear body 51 of the upper guide drive. From the second deflection pulley 24, the pull cable 22 is guided further to a pull cable connection 72, which is arranged on the upper stop device 7 (see Fig. 5 ).

[0085] By moving the deflection unit 230 along the mounting profile 14, the path from the pulley 212 to the second deflection pulley 24 can be lengthened or shortened. Lengthening this path extends a corresponding length of the pulley 22 from the drive unit 21, rotates the pulley 212 accordingly, and pre-tensions the drive element 211. Pre-tensioning the drive element 211 therefore causes it to exert a greater tensile force on the pulley 22, moving the mounting profile 14 with greater force from the first end position S1 towards the second end position S2. This adjustment can be easily made in just a few steps.

[0086] Fig. 4 Figure 1 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 retaining plate 5112.

[0087] The first drive body part 511 also holds a bearing shaft 415, from 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 roller pair 41, are part of the holding device 4, which is explained below. A functional part 57 rests above the roller pair 41, which carries the Fig. 6 secured by the holding cables 421, 422 shown.

[0088] In the second running gear body part 512 a damper channel 5120 is provided in which a running gear damper 58 is arranged and fixed by means of a locking element, optionally a fixing screw 5121.

[0089] Fig. 5 shows the upper part of the sliding device 10 of Fig. 2 with the drive device 2, from which the pull rope 22 is guided via the first deflection pulley 23 of the deflection unit 230 which is slidably connected to the mounting profile 14 and the second deflection pulley 24 which is connected to the upper guide carriage 5 to a pull rope connection 72 on the upper stop device 7, which is held on the front of the upper guide rail 15.

[0090] To put the drive device 2 into operation, the coupling part 221 is grasped at the end of the pull rope 2, guided around the first and second deflection pulleys 23, 24 and hooked into the pull rope connection 72 of the upper stop device 7. This process can be carried out in just a few steps.

[0091] The stop device 7 is equipped with a mounting beam 711 (see Fig. 8b ) in a retaining channel 157, which is provided on the underside of the running element 151 of the upper guide rail 15. Above the running element 151, therefore, is the running mechanism with the support rollers 591 and the guide rollers 592 of the upper guide carriage 5 (see Fig. 3 ) and an adjusting part 159 for adjusting the damper engagement depth is provided, which can interact with the running gear damper 58. On the underside of the running gear element 151, on the other hand, the drive mechanism with the pull cable 22 and the holding mechanism of the holding device 4 with holding cables 421, 422 are provided (see also Fig. 6 ).

[0092] Depending on whether the door has one door element 111 or two door elements 111, 112, the stop device 7 comprises one or two spacer rollers 79 on one side or one on each side, on which the held door elements 111, 112 can roll without touching the body 71 of the stop device 7. The upper stop device 7 also includes a cable connection device 74, by means of which one of the retaining 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 element 53 of the upper guide track 5 (see Fig. 4 ).

[0093] Fig. 6 The sliding device 10 of Fig. 2 with a holding device 4 according to the invention, comprising two holding cables 421, 422.

[0094] The upper guide carriage 5, located at the top end of the mounting profile 14, is guided in the upper guide rail 15, and the lower guide carriage 6, located at the bottom end of the mounting profile 14, is guided in a lower guide rail 16. The upper stop 7 is shown on the front of the upper guide rail 15, and the lower stop 8 is shown on the front of the lower guide rail 16 (see also Fig. 7 ). In Fig. 6 Guide rails 15 and 16 are not shown.

[0095] The upper front-facing stop device 7 with the mounting beam 711, the pull rope connection 72 and the rope connection device 74 for the second retaining rope 422 has already been described with reference to Fig. 5 The rotary lever 75 serves to hold the mounting profile 14 in the front 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 mounted particularly easily. The upper cable connection device 74 includes a mounting channel 741 (see Fig. 8b ) with a subsequent recess into which an end piece of the upper retaining rope 422 can be inserted.

[0096] The lower stop device 8 and the upper stop device 7 are described below with reference to Fig. 8a und Fig. 8b The second pull rope 422 is held by the pull rope connection 74 of the upper stop device 7. The pull rope 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 rope 421 can be tightened or loosened and the mounting profile 14 can be vertically aligned.

[0097] The holding device 4 comprises a first front-facing rope 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-facing rope connection device 44 arranged at the rear end of the upper guide rail 15, as well as the first holding rope 421, which is connected at a first end piece to the first front-facing rope connection device 84, guided counterclockwise around the first lower roller unit 431 and clockwise around the first upper roller unit 411, and connected at a second end piece to the first rear-facing rope connection device 44.

[0098] Furthermore, the holding device 4 comprises a second front-facing rope connection device 74, a second upper roller unit 412 arranged at the upper end of the mounting profile 14, a second lower roller unit 432 arranged at the lower end of the mounting profile 14, and a second rear-facing rope connection device 45 arranged at the rear end of the lower guide rail 16, as well as the second holding rope 422, which is connected at a first end piece to the second front-facing rope connection device 74, guided clockwise around the second upper roller unit 412 and counterclockwise around the second lower roller unit 432, and connected at a second end piece to the second rear-facing rope connection device 45.

[0099] In this preferred embodiment, the first front-facing cable connection device 84 is provided at the front end of the lower guide rail 16 on the lower stop device 8. In this preferred embodiment, the second front-facing cable connection device 74 is arranged at the front end of the upper guide rail 15 on the upper stop device 7.

[0100] The second rear cable connection device 45 comprises a second tensioning device 450 with a second tension spring 453, which is connected on one side directly or via a second connection slide 452 (shown in dashed lines) to the second retaining cable 422 and on the other side 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 is displaceable 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 retaining cable 422.

[0101] In the holding device 4 according to the invention, one of the retaining cables, in this embodiment the second retaining cable 422, is therefore always held elastically. After installation, the first retaining cable 421, however, is held inelastically or rigidly by the first front cable connection device 84 and the first rear cable connection device 44. The vertical alignment of the mounting profile 14 can be carried out 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 cable connection device 44.

[0102] Preferably, the second tension spring 453 is pre-tensioned or stretched by a predetermined amount. If the second tension spring 453 is connected on one side to the tension slide 454 and on the other side to the connecting slide 452, the degree of relative displacement of the tension slide 454 and the connecting slide 452 corresponds to the tensile force in the tension spring 453. The applied tensile force can therefore be easily determined from this displacement. When using a connecting slide 452, the retaining cable 422 can be connected more easily, as described below.

[0103] With reference to Fig. 7 It is further explained that preferably a tensile force is also applied to the first retaining cable 421 before it is fixed. Applying a tensile force to the second retaining cable 422, or to both the first and second retaining cables 421, 422, results in the advantages described above.

[0104] The preferably provided drive device 2, which is held by the upper guide carriage 5, was designed with reference to Fig. 3 As already described, the pull cable 22 of the drive device 2 is guided via the first deflection pulley 23 and the second deflection pulley 24 to the pull cable connection 72, which is provided on the upper front stop device 7. The deflection unit 230 is positively locked in the first guide channel 141 by a shaped element 232 and is slidable along the mounting profile 14.

[0105] Fig. 7 The sliding device 10 of Fig. 6 with the two rear cable connection devices 44, 45 of the holding device 4, each having 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 comprising a tension spring 443, 453, have therefore been duplicated and are shown separately. The tension springs 443, 453 are also shown separately.

[0106] Each of the rope connection devices 44, 45 comprises an input roller 441, 451, a connection 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 end of the associated retaining cable 421, 422 is guided over the input roller 441, 451 to the connecting slide 442, 452, which is connected by the tension spring 443, 453 to the pull 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 pull 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 via the connecting slide 442, 452 to the connected retaining cable 421, 422. The aforementioned parts of the cable connection 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.

[0107] With reference to Fig. 6 It was described that the connecting slide 452 is only optionally provided in the second rope connection device 45. In the first rope connection device 44 of Fig. 7 , which preferably also includes a clamping device 440, the connecting slide 442 is always present so that the first pull rope 421 can be fixed after the pulling force has been applied.

[0108] If the first connecting slide 442 is fixed in the first retaining cable 421 after the tensile force has been set, 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 screw passes through the profile opening 4490 in the bearing profile 449 and is clamped to the bearing profile 449 when tightened. Parts of the bearing profile 449 are therefore shown symbolically below the fixing screw 448.

[0109] The installation of the sliding device according to the invention is preferably carried out as follows: The mounting profile 14 is aligned vertically and preferably fixed in place. Fixing is achieved, for example, by the locking levers 75, 85 on the stop devices 7 and 8. The first retaining cable 421 is connected at a first end piece to the first front 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 at a second end piece to the first rear cable connection device 44 and manually tensioned. The roller units 411, 431 are rotated once clockwise and once counterclockwise by the first retaining cable 421, or vice versa.The second retaining cable 422 is connected at a first end piece to the second front 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 at a second end piece to the second rear cable connection device 45 and manually tensioned. The roller units 412, 432 are rotated once clockwise and once counterclockwise by the second retaining cable 421, or vice versa. The second retaining cable 422 is connected to the second connecting slide 452 in the second rear cable connection device 45, after which the second tensioning screw 455 is turned 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 moved relative to each other by a predetermined amount. The first front adjusting slide 842 of the first front adjusting device 840 of the first front cable connection device 84, which is connected on one side to the fixed first retaining cable 421, is now adjusted by means of the stationary 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.

[0110] After completion of the installation procedure, a predetermined tensile stress is imprinted in the second retaining cable 422 and the mounting profile 14 is vertically aligned by means of the tensioned first retaining cable 421.

[0111] This installation process is optimized by imprinting a predetermined tensile force on the first retaining cable 421 before adjusting or vertically aligning the mounting profile 14. After imprinting a predetermined tensile force on both retaining cables 421 and 422, the effort required for adjusting or vertically aligning the mounting profile 14 is reduced.

[0112] In preferred embodiments of the installation method, the first retaining cable 421 is additionally connected to the first connecting slide 442 in the first rear cable connection device 44, after which the first tensioning screw 445 is turned and the first pull slide 444 and the first connecting slide 442, which are connected to each other by the first tension spring 443, are displaced relative to each other by a predetermined amount.

[0113] After this step, the predetermined tensile forces are imprinted in both pull ropes 421, 422. These settings are preferably made taking into account the measuring rods, which indicate the degree of mutual displacement of the connecting slides 442, 452 and the pull slides 444, 454, preferably on a scale with markings, optionally color markings.

[0114] The first connecting slide 442 is fixed to the associated first bearing profile 449 after the predetermined tensile stress has been applied. Subsequently, as described, the first front-facing adjusting device 840 is actuated to vertically align the now unfixed mounting profile 14. Only minimal adjustments are typically necessary at this stage.

[0115] Fig. 7 The figure symbolically shows that, optionally, a second drive unit 2' and a second slidably mounted deflection unit with a first deflection pulley 23' can also be provided on the underside of the mounting profile 14. The lower pull cable would then be guided via the first deflection pulley 23' and a deflection pulley, which is attached, for example, to the lower guide carriage 6, to a pull cable connection 82 on the lower stop device 8. A second drive unit 2' and the corresponding device components can therefore be provided with minimal effort, practically as a mirror image of the first drive unit 2.

[0116] Fig. 8a shows the upper stop device 7 and the lower stop device 8 of Fig. 7 in spatial representation. Fig. 8b shows the upper stop device 7 and the lower stop device 8 of Fig. 7 in sectional view.

[0117] The upper stop device 7 and the lower stop device 8 each have a device body 71, 81 and an integrally formed mounting beam 711, 811, which can be locked in the associated upper or lower guide rail 15, 16 by means of locking screws 712, 812. The upper stop device 7 has a hook-shaped pull rope connection 72 in which the coupling part 221 of the pull rope 22 can be hooked.

[0118] 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 to carry out installation, maintenance or adjustment work. 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 retaining bracket 710, 810, which is connected to the device body 71, 81 by a screw.

[0119] 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.

[0120] The rope connection device 74 of the upper stop device 7 is of simple design and has a retaining block 742 with an upwardly open mounting channel 741 into which an end piece of the second retaining rope 422 can be hooked.

[0121] The lower stop device 8 comprises a cable connection device 84 with an adjusting device 840, which is formed by a movable adjusting carriage 842 and an adjusting screw 845, by means of which the adjusting carriage 842 is movable within a bearing profile 843. The adjusting carriage 842 has a mounting channel 841 into which the end piece of the first retaining cable 421 can be hooked.

[0122] Furthermore, the lower stop device 8 has a plunger 86 which can be axially displaced by means of an adjusting screw 861 and which can interact with the integrated drive damper 68 of the lower guide drive 6.

[0123] Fig. 9a shows the upper rear rope connection device 44 and Fig. 9b shows the lower rear rope connection device 45, which relates to Fig. 7 as already briefly described.

[0124] The input roller 441 of the upper rear rope connection device 44 is held by a roller bracket 4411, which can be clamped within the bearing profile 449 by means of a clamping element 4412. The input roller 451 of the lower rear rope connection device 45 is held by a roller bracket 4511, which can be clamped within the bearing profile 459 by means of a clamping element 4512.

[0125] 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 fix the end piece of the respective retaining cable 421, 422 inserted between them. The retaining cables 421, 422 can therefore be pulled through the connecting slides 442, 452, manually tensioned and fixed.

[0126] 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.

[0127] 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 retaining cables 421, 422 can be adjusted. A measuring rod 447, 457 with a viewing window 4570 is provided for setting a desired tensile force. The measuring rod 457 is connected to the connection slide 452 and overlaps a scale 4471, 4571, which is provided on the tension slide 444, 454. The relative displacement of the connection 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.

[0128] Fig. 10 shows the auxiliary drive 3 of Fig. 2 The auxiliary drive 3 comprises a housing 33 and at least one extendable piston 32, which is supported by a spring element 31 and 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 assist the drive device 2 at the beginning of the extension of the mounting profile 14 towards the second end position S2.

[0129] The mounting profile 14 is also connected to a cyclically operating locking device 95, which comprises an actuating rod 952 and a gripper 951. The gripper interacts with a stationary gripping element 96 and can be cyclically locked and unlocked by pressing on the actuating rod 952. A first movement 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 movement of the actuating rod 952 opens the gripper 951. The actuating rod 952 is preferably arranged coaxially with the central axis of the gripper 951, so that the gripping element 96 can actuate the actuating rod 952, which is then grasped and released by the gripper 951. The gripping element 96 is arranged on the stop plate 9 of the stop device 90, which is attached to the partition wall 1D functional unit 1.The displacement path of the actuating rod 952 is shown by a dashed line. Shortly before reaching the end position S1, it encounters the gripping element 96 and is pushed back by it, thereby actuating the gripping device 95 and coupling it to the gripping element 96.

[0130] Furthermore, damping devices 99 with damping pistons 991 are provided, which strike the stop plate 9 as soon as the mounting profile 14 reaches the end position S1.

[0131] The auxiliary drive 3, the gripping device 95 and the damping devices 99 are optional and can be replaced by functionally equivalent devices.

[0132] Fig. 11 Figure 1 shows an assembly configuration of the sliding device 10, comprising an assembly profile set 14' which detachably holds the upper guide carriage 5 and the lower guide carriage 6, an upper guide rail set 15' which detachably holds the upper stop device 7 and the first rear rope connection device 44 and is connected to the upper guide carriage 5, a lower guide rail set 16' which detachably holds the lower stop device 8 and the second rear rope connection device 45 and is connected to the lower guide carriage 6, and the pre-assembled retaining ropes 421, 422.

[0133] The retaining cables 421, 422 are connected at the front to the cable connection devices 74, 84 of the stop devices 8, 7 and at the rear to the cable connection devices 44, 45.

[0134] Fig. 11 further shows one of the partition walls 1D of Fig. 1, on which the lower and upper guide rails 15, 16 are already mounted and onto which the sliding device 10, as present in the assembly configuration, is transferred. Installation is particularly easy if the partition wall 1D is aligned horizontally.

[0135] To install the sliding device 10 as it is presented in the assembly configuration, it is therefore only necessary to replace the mounting profile set 14' with the mounting profile 14 and the upper and lower guide rail sets 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.

[0136] The assembly configuration of the sliding device 10 can therefore be advantageously created by the manufacturer, while the installation of the sliding device 10 at the installation site can be carried out by the user in a simple manner with almost no instructions, for example with the installation steps described below.

[0137] Preferably, in a first installation step, the mounting profile replacement 14' is replaced by the mounting profile 14.

[0138] In a second installation step, the guide carriages 5, 6, now connected to the mounting profile 14, are inserted into the associated upper or lower guide rail 15, 16 connected to the partition wall 1D.

[0139] In a third installation step, the stop devices 7, 8 are detached from the upper and lower guide rail sets 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.

[0140] In a fourth installation step, the rear rope connection devices 44, 45 are detached from the upper and lower guide rail sets 15', 16' and connected to the upper and lower guide rails 15, 16. For this purpose, a mounting strip 4495 of the first rear rope connection device 44 is screwed to a mounting connector 154 of the upper guide rail 15. The second rear rope connection device 45 is inserted into the mounting channel 163 of the lower guide rail 16 using a mounting beam 45111, which is connected to the associated roller bracket 4511.

[0141] In a final installation step, the upper guide rail assembly 15' is detached from the upper guide carriage 5 and the lower guide rail assembly 16' is detached from the lower guide carriage 6.

[0142] After these installation steps, which are also interchangeable, the inventive sliding device 10 is connected solely to the upper and lower guide rails 15, 16.

[0143] Subsequently, the retaining cables 421, 422 are tensioned as already described. Reference symbol list:
