Sliding device with a mounting profile and functional unit

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 can be automatically moved within a door compartment, and to a functional unit, in particular a piece of furniture or a room unit, with at least one such sliding device.

[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] EP1394349A1 discloses a sliding device for a door element which can be rotatably connected to a slidably mounted guide rail which is held perpendicular to the direction of movement by means of two flexible connecting elements.

[0006] Also known are sliding devices in which a mounting profile connected to a sliding door can be automatically moved within a door compartment by means of a drive device.

[0007] WO2021119696A1 discloses a guide arrangement for at least one door leaf of a piece of furniture, comprising a guide rail on which a drive device is arranged by means of which the door leaf can be moved.

[0008] DE202020107104U1 discloses a further guide arrangement for at least one door leaf of a piece of furniture with a drive device comprising a pull cable for driving the movable furniture part, a cable drum for winding and unwinding the pull cable, a spring device for driving the cable drum, and an adjusting device for setting a preload of the spring device. The adjusting device is integrated into the drive device, which makes manufacturing the drive device more complex. This is particularly significant if several drive devices with different specifications are to be provided. Furthermore, it should be noted that adjusting the preload requires access to the drive device installed in the piece of furniture, which necessitates either careful mounting of the drive device or modification of the furniture.

[0009] DE2847578A1 discloses a guide device with an elongated guide body to which, for example, a cabinet door can be attached and moved along a guide rail and which is held by a rope so as to be moved parallel to itself.

[0010] The present invention is therefore based on the objective of creating an improved sliding device with a drive device comprising a pull cable connected to a spring device, by means of which a mounting profile, which is connected or connectable to a one-piece or multi-piece door, can be automatically moved within a door compartment of a functional unit, a piece of furniture or a room unit.

[0011] Furthermore, a functional unit, a piece of furniture or a room unit, with at least one improved sliding device is to be created, by means of which a mounting profile connected to a door, possibly a folding sliding door, can be automatically moved within a door compartment of the functional unit.

[0012] The inventive sliding device is intended to allow the preload of the spring device to be advantageously adjusted by means of an adjusting device in order to influence the movement sequence of the mounting profile during the sliding.

[0013] The drive device should be inexpensive to manufacture and require as little maintenance as possible over a long operating period.

[0014] The sliding device should be easy to install, so that the drive device can be put into operation without any problems using the pull rope.

[0015] The sliding device should be advantageously adjustable by both skilled personnel and users, so that the mounting profile can be driven with a desired force within a preferably adjustable range. In particular, the sliding device should be advantageously adaptable to different loads from door elements connected to the mounting profile.

[0016] This problem is solved by a sliding device according to claim 1 and an improved functional unit according to claim 14, 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.

[0017] The sliding device, which is intended for installation in a door compartment of a functional unit, includes a drive device which, in preferred embodiments, comprises a housing, a spring device, a pull cord pulley coupled to the spring device, and a pull cord wound onto the pull cord pulley and guided, optionally via at least one deflection pulley, to a holding element; a mounting profile which is connected or connectable to a one-piece or multi-piece door by stop hinges and is vertically aligned and slidably held by a holding device; which is connected at an upper end piece to an upper guide carriage which is slidably mounted on an upper guide rail, and / or at a lower end piece to a lower guide carriage which is slidably mounted on a lower guide rail;and a mounting profile connected to the drive device that is automatically movable between a rear end position of the sliding device and a front end position of the sliding device; and an adjusting device by means of which a preload on the spring device of the drive device can be adjusted.

[0018] According to the invention, the adjusting device is arranged separately from the drive device and comprises an adjusting element which is rotatable and lockable and preferably slidable and lockable and which adjusting element interacts with the pull rope led out of the housing of the drive device in such a way that the pull rope can be extended from the drive device by rotating and preferably sliding the adjusting element and a corresponding preload of the spring device can be adjusted.

[0019] The adjusting device used to set the preload is not integrated into the drive unit, but is implemented by means located outside the drive unit. These means allow the pull cable to be extended from the drive unit to adjust the preload on the spring unit. The spring unit is thus preloaded by unwinding the pull cable from the pull cable pulley, rotating the pull cable pulley, and tensioning the spring unit accordingly.

[0020] Therefore, a complex drive mechanism with an integrated preload adjustment device is unnecessary. The drive mechanism can thus be simpler, more compact, and more robust, and can be manufactured more easily and cost-effectively, which largely eliminates the need for maintenance and repairs, even after extended periods of operation.

[0021] It is particularly advantageous that the parts of the adjusting device to be adjusted can be arranged on an easily accessible part of the sliding device.

[0022] The range in which the preload of the spring device is adjustable is not specified by a manufacturer, but can be freely chosen for the sliding device according to the invention.

[0023] The drive device allows the mounting profile to be moved automatically in one direction towards the front end position or alternatively in the other direction towards the rear end position.

[0024] The preload of the spring mechanism causes it to exert a greater tensile force on the pull cable, thus moving the mounting profile with greater force, for example, from its rear end position towards its front end position. The preload is preferably adjusted taking into account the weight of the door connected to the mounting profile. The desired preload can be achieved in various ways. It can be adjusted incrementally, for example, using detents, or continuously.

[0025] According to the invention, an adjustment device is provided with a rotatable adjusting element, namely a rotatable rope drum. Additionally, an adjustment device with a movable adjusting element, namely a movable deflection unit, can be provided.

[0026] The first adjusting device tensions the spring mechanism by shortening the length of the pull rope, which is wound onto the pull rope pulley inside the drive unit and led to the first adjusting device. For this purpose, the free end of the pull rope, which extends from the housing of the drive unit, is wound onto the rotating rope drum as needed.

[0027] The second adjusting device tensions the spring device by lengthening or shortening the path along which the pull rope runs from the drive device to the stationary holding element by moving a deflection unit.

[0028] When the first and second adjusting devices are actuated, the pull rope is extended or released from the housing of the drive device in order to adjust the preload of the spring device.

[0029] Preferably, the adjustment device comprises two adjustment devices: a first adjustment device with a rotatable adjusting element and preferably a second adjustment device with a sliding adjusting element. One of the adjustment devices preferably serves for coarse adjustment of the preload, and the other adjustment device preferably serves for fine adjustment of the preload. Preferably, the coarse adjustment of the preload is carried out by means of a sliding adjusting element, and the fine adjustment by means of a rotatable adjusting element.

[0030] According to the invention, the first adjusting device is stationary at the front end position of the sliding device at the access to the door compartment. The first adjusting device has a housing with a housing chamber in which the cable drum is rotatably and lockably mounted about its longitudinal axis, hereinafter referred to as the drum axis.

[0031] The locking mechanism of the rope drum can be implemented in various ways. Preferably, locking elements are provided on the rope drum which can interact with at least one counter element on the housing and which can be released from each other, for example, by axial displacement of the rope drum or by displacement of the at least one counter element, in order to allow the rope drum to be rotated.

[0032] Preferably, the upper guide rail is connected at the front to an upper stop device which determines the front end position of the sliding device, or the lower guide rail is connected at the front to a lower stop device which determines the front end position of the sliding device, or the upper guide rail is connected at the front to an upper stop device and the lower guide rail is connected at the front to a lower stop device which determines the front end position of the sliding device, and the adjusting device is mounted on or integrated into the upper stop device or the lower stop device.The adjustment device mounted on the upper or lower stop is therefore easily accessible on the front of the piece of furniture, which is why a desired preload of the drive device can be conveniently adjusted.

[0033] Preferably, the cable drum is connected on a first side coaxially to the drum axis with a tool coupling part, which is preferably aligned against the front of the displacement device and thus against the front of the piece of furniture and is therefore easily accessible in order to couple a tool and rotate the cable drum.

[0034] The housing chamber preferably comprises a tool chamber in which the tool coupling part is rotatably and slidably held, a locking chamber into which at least one counter element, such as a retaining lug, a wing or rib, preferably integrally connected with the housing, projects, and a drum chamber in which the rope drum is rotatably and preferably axially slidably held.

[0035] The cable drum preferably comprises a winding body, preferably cylindrical, onto which the traction cable can be wound, and to which a first drum wall is attached on one side and a second drum wall on the other. The first drum wall is preferably integrally connected to the tool coupling part and preferably integrally connected to at least one locking element, which is rotatable within the locking chamber against the at least one counter element. The second drum wall preferably rests against an elastic element, such as a drum spring, preferably a helical spring, which presses the cable drum against the locking chamber, so that the at least one locking element is in the engagement area of ​​the counter element and can only be released from the locking chamber when the cable drum is axially displaced by exerting counter pressure.Preferably, several cooperating locking elements are provided on the first drum wall and / or several counter elements are provided on the housing, so that adjustment in correspondingly small steps is possible.

[0036] The rope drum preferably has a threaded rod aligned coaxially to the drum axis following the second drum wall, by which a slide is rotatably held, and the housing of the adjusting device has a bushing chamber in which a bearing bushing is held, which has a bushing channel into which the threaded rod projects and within which the slide is axially displaceable but not rotatable and can be moved to an end stop by rotating the rope drum in one and / or the other direction.

[0037] The slide preferably has at least one slide wing that projects into a bushing slot adjoining the bushing channel and is guided therein so as to be displaceable parallel to the drum axis. The slide is therefore not rotatable, but is displaceable along the bushing slot until it encounters a first, second, or third end stop, which may be formed, for example, by the housing, a part of the bearing bushing, optionally the ends of the bushing slot, or the cable drum.

[0038] In a further preferred embodiment, the housing chamber of the housing can be closed off by a cover, which is preferably designed to be complementary to the housing.

[0039] Preferably, a mounting fork can be inserted into the cover, allowing the cable drum and drum spring to be fixed to the cover. The cable drum and drum spring can therefore be placed on the cover, secured with the mounting fork, and then easily inserted into the housing of the adjusting device. The mounting fork is then removed, thereby activating the drum spring. The activated drum spring then preferably rests against the second drum wall and preferably against a part of the housing.

[0040] Preferably, the movable adjusting element of the adjusting device is a deflection unit, which deflection unit holds a first deflection pulley over which the pull rope is guided from the drive device to a second deflection pulley and further to a stationary holding element, which deflection unit is directly or indirectly connected to the mounting profile, which deflection unit is slidably mounted along the mounting profile with respect to the housing of the drive device and with respect to the second deflection pulley, which is directly or indirectly connected to the mounting profile or to one of the guide carriages,

[0041] The preload of the spring device can therefore be adjusted by shifting and locking the deflection unit.

[0042] The pull cable 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 to it. Preferably, the pull cable runs at least approximately parallel to the mounting profile in each case. Thus, the first part of the pull cable preferably runs parallel to the mounting profile, and the second part preferably runs parallel to the lower and / or upper guide rail.

[0043] The axes of rotation of the first and second deflection pulleys, which are held by bearing shafts, are parallel or inclined, preferably perpendicular to each other. This allows the pull cable to be guided particularly advantageously, especially parallel to the mounting profile and horizontally to the holding element.

[0044] Preferably, the end piece of the pull cable located away from the drive device or its housing is provided with a coupling element, a hook, an anchor, a locking element, a rod, or a loop that can be hooked or locked into the retaining element. In this way, the pull cable can be mounted with just a few steps.

[0045] The deflection unit is preferably held in a guide channel of the mounting profile by a positive-locking and / or force-locking mechanism, allowing it to be slidably and lockably secured. The deflection unit is thus preferably slidable parallel to the longitudinal axis of the mounting profile and can be fixed in a suitable position by means of a locking device, such as a fixing screw. For example, a part of the deflection unit body corresponding to or complementing the guide channel engages positively in the guide channel. 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 by moving the deflection unit with a single hand movement.

[0046] The retaining element for connecting the pull rope is preferably arranged on a stop device, which is preferably mounted on the front of the upper or lower guide rail and which forms an end stop for the upper or lower guide carriage with a stop buffer.

[0047] By providing the retaining element for the pull cable on the stop device, it is ensured that the pull cable is guided close to the facing guide rail and that the space within the door compartment is kept largely clear. The sliding device according to the invention therefore allows for the advantageous use of different retaining devices.

[0048] Regardless of the design of the sliding device according to the invention, the drive device is preferably connected to the mounting profile and is slidable with the mounting profile parallel to the guide rails. However, according to the invention, it is also possible to mount the drive device in a stationary position and to guide the pull cable to the first or second adjustment device via a deflection pulley provided on the mounting profile.

[0049] The drive unit is preferably positioned laterally to the mounting profile or laterally to one of the guide carriages, relative to the mounting profile's axis of displacement or travel path. This arrangement of the drive unit prevents a reduction in travel path. It also prevents the drive unit housing from contributing to the cabinet's overall depth loss due to the mounting profile.

[0050] 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.

[0051] In preferred embodiments, the spring device of the drive device is a tension spring, such as a helical spring or a spiral spring, and the drive cable is wound onto a pulley which is rotatably mounted and connected to the spring device. Rotating the pulley in one direction tensions the spring device, and rotating the pulley in the other direction releases the sliding device. However, with regard to the sliding device according to the invention, the manner in which the drive cable is arranged and the design of the spring device are immaterial.

[0052] Preferably, two identical or co-acting drive devices are provided, which are rigidly connected to the mounting profile or each of the guide carriages and are movable together with the mounting profile, and which each have a pull 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 holding element, which is stationary at the front or rear end position of the travel path and is connected to it.

[0053] The use of two drive units, preferably arranged in a mirror-image or symmetrical configuration, offers several advantages. The space required for the second drive unit is therefore also minimal. The drive forces of the two units combine, allowing the mounting profile with the attached door to be moved with greater acceleration. Furthermore, instead of one larger drive unit, two smaller drive units can be used, each requiring less space and thus, with greater overall drive power, requiring less space overall. This also allows for a smaller cross-section for the moving part of the sliding mechanism. Paradoxically, the space required for the sliding mechanism within the door frame can be reduced by using two drive units.Furthermore, by using two drive devices, torques caused by the first drive device can be compensated, thus further increasing the driving effect.

[0054] The holding devices described at the outset include, for example, a scissor cross or a parallelogram or, as shown in the exemplary embodiments, two holding cables by means of which the mounting profile is held vertically aligned.

[0055] The sliding device according to the invention can be used for any functional unit that comprises a lockable space and is generally bounded by walls or partitions. The sliding device according to the invention has a compact design and requires little space, which is why the associated door compartment can also be implemented with small dimensions, leaving a relatively large amount of usable space within the functional unit. The door compartment can therefore accommodate small as well as large single- or multi-part doors, optionally folding sliding doors, which are connected to the mounting profile by stop hinges.

[0056] 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 the usable space of the functional unit can be closed off on both sides of the door compartment.

[0057] The functional units can consist of spaces bounded by wooden walls and include furniture, especially cabinets. Alternatively, functional units can also consist of spaces bounded by walls, which can be closed off by means of single or multi-part doors, possibly folding sliding doors.

[0058] The sliding device used is preferably designed in such a way that the first and second adjusting devices can be actuated on the front of the functional unit.

[0059] The invention is explained in more detail below by means of embodiments shown in the drawings. This shows:

[0060] 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, which is connected to a folding sliding door 11, is automatically slidable by means of a sliding device 10 according to the invention, and a second door compartment 18 in which a further mounting profile 14, which is connected to a one-piece door 11, is automatically slidable by means of a sliding device 10 according to the invention; Fig. 2 shows the first door compartment 18 of the functional unit 1. Fig. 1 arranged sliding device 10 with the mounting profile 14, which is connected to a drive device 2 and optionally to an auxiliary drive 9, which is held in a vertical orientation by a holding device 4, and which is connected to the folding sliding door 11 by stop hinges 131; Fig. 3 shows a part of the sliding device 10. 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, which includes a drive unit 21, which holds a cable pulley 212 coupled to a sliding device 211, which is connected to a spring device 211 and is wrapped by a pull rope 22; Fig. 4 the sliding device 10 of Fig. 2 with a preferably provided holding device 4 and with the mounting profile 14, which is connected to the drive device 2, from which the pull rope 22 is guided via three deflection pulleys 231, 232 and 233 to a first adjusting device 3, which is mounted on an upper front stop device 7; Fig. 5 the sliding device 10 of Fig. 2 with a preferred holding device 4 and with the mounting profile 14, which is connected to the drive device 2, from which the pull rope 22 is guided via a second adjusting device X3, which has a deflecting unit X33 that is movable and lockable along the mounting profile 14, to a holding element 72, which is arranged on the upper front stop device 7; Fig. 6 shows the upper front stop device 7 and the first adjusting device 3 associated with it. Fig. 4 from the rear; Fig. 6b the upper front stop device 7 and the associated first adjustment device 3 of Fig. 6a with a detached cover 39 from the front, from which the first adjusting device 3 can be adjusted; Fig. 6c the upper front stop device 7 and the associated first adjusting device 3 of Fig. 6a in a sectional view; Fig. 6d the upper front stop device 7 and the associated first adjusting device 3 of Fig. 6b in a sectional view; Fig. 7 the first adjusting device 3 of Fig. 6b without cover 39; Fig. 7b the housing 38 of the first adjusting device 3 of Fig. 7a ; Fig. 8 the rope drum 33, the bearing bushing 34, the drum spring 35, the slide 36 and the cover 39 of the first adjusting device 3 of Fig. 7a in exploded view; Fig. 9 the first adjusting device 3 of Fig. 4 during the process of adjusting the preload on the drive device 2; and Fig. 10 the auxiliary drive 9 of Fig. 2 , which is held by the mounting profile 14 and which, after the sliding door 11 is inserted into the door compartment 18, interacts with a rear stop device 90.

[0061] 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. The mounting profile 14 is automatically movable within the door compartment 18 without an electric drive motor. Doors 11 are held by the mounting profile 14 and are moved into or out of the corresponding door compartment 18 when the mounting profile 14 is moved.

[0062] 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 and is therefore a single unit.

[0063] The folding sliding door 11 is fully extended from the first door compartment 18 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 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.

[0064] The trailing edge of the first door element 111 of the folding sliding door 11 when the sliding door 11 is extended is connected by stop hinges 131 to the mounting profile 14 shown symbolically, which is held at the front end position of the sliding device 10 after the sliding door 11 has been extended at the exit of the door compartment 18.

[0065] 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 track 5F. The front track 5F is guided in a support rail 150. When entering the door compartment 18 and when traveling along the support rail 150, the front track 5F always runs ahead, with the change of direction occurring within a curve.

[0066] Fig. 2 shows the functional unit 18 in the first door compartment of Fig. 1 arranged sliding device 10 with the mounting profile 14, which is connected to a drive device 2 and optionally to an auxiliary drive 9, which is held in a vertical orientation by a holding device 4 shown symbolically, and which is connected to the folding sliding door 11 by the stop hinges 131.

[0067] The mounting profile 14 is movable along a travel path S between the front end position S1 at the front of the door compartment 18 and a rear end position S2 at the back of the door compartment 18.

[0068] As this is in Fig. 5 As shown, the mounting profile 14 is preferably connected at its upper end piece to an upper guide carriage 5, which is guided in an upper guide rail 15, and at its lower end piece 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 supporting function. The lower guide carriage 6 comprises a lower carriage body 61 with guide rollers 692, which are guided in the lower guide rail 16.

[0069] The upper guide drive 5 and the lower guide drive 6 are located in Fig. 2 at the front end position S1 on an upper stop device 7 and on a lower stop device 8, which are in Fig. 5 shown.

[0070] At the rear end position S2, a stop device 90 with a stop plate is provided, which limits the travel path S of the mounting profile 14 on the rear of the door compartment 18.

[0071] The inventive sliding device 10 comprises a drive device 2 with a pull cable 22, which is connected within the housing 210 of the drive device 2 to a spring device 211, and which is in Fig. 2 not yet mounted. By means of this drive device 2, the mounting profile 14 is preferably displaceable over the entire travel path S. For adjusting a preload on the spring device 211, a first adjusting device 3 and preferably a second adjusting device X3 are provided, which are described in more detail below. These adjusting devices 3, X3 are arranged outside the housing 210 of the drive device 2 and allow the pull cable 22 to be pulled out of the drive device 2. The sliding device 10 can therefore be equipped with simple and universally applicable drive devices 2, which have a pull cable 22 with a spring device 211 but no integrated adjusting device.

[0072] 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 preferably 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.

[0073] Optionally, an auxiliary drive 9 is provided, by means of which the at least one drive device 2 is supported in the area of ​​the rear end position S2. As soon as the mounting profile 14 is released from the rear end position S2 or from the stop device 90, it is additionally accelerated over a relatively short distance by the auxiliary drive 9. The auxiliary drive 9 enables a rapid movement sequence. The mounting profile 14 does not move sluggishly from the rear end position S2, but is rapidly accelerated. The auxiliary drive 9 preferably has an extendable piston 91, which is supported by a spring that stores the drive energy.

[0074] Above and below the auxiliary drive 9, damping devices 99 are provided which have a damping piston 991 which is displaced when it hits the stop device 90 and dampens the movements of the mounting profile 14 and avoids a disruptive impact.

[0075] Between the two damping devices 99, a cyclically operating locking device 95 is also provided, comprising an actuating rod 952 and a gripper 951, which can interact with a stationary gripping element 96 and can be cyclically locked and unlocked by pressure on the actuating rod 952, which is exerted by the gripping element 96 when the rear end position S2 is reached. Thus, the locking device 95 can be locked by manually applying pressure and unlocked by further pressure.

[0076] 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 the upper guide carriage 5, which is slidably mounted in the upper guide rail 15 and which is connected to the drive device 2.

[0077] By connecting the drive device 2 with the mounting profile 14 or the guide carriage 5, the need to mount the drive device 2 on a rear wall, a partition wall 1D or a side wall 1A of the functional unit 1 is eliminated.

[0078] The upper guide carriage 5 comprises a carriage body 51 with a first carriage body part 511, which holds vertically oriented support rollers 591 and horizontally oriented guide rollers 592, and a second carriage body part 512, which is connected to the mounting profile 14. The two carriage body parts 511, 512 can be integrally joined, but in this embodiment they are connected 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 element 53, which can interact with a buffer or damper 78 on the front-facing stop device 7 (see Fig. 4 ).

[0079] The mounting profile 14 preferably has 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.

[0080] The drive device 2 comprises a drive unit 21 with a housing 210 in which a spring device 211 is arranged and a pulley 212, connected to the spring device 211 and onto which the pull rope 22 is wound, is rotatably mounted. The spring device 211 is preferably a drive spring, for example in the form of a spiral spring or a helical spring, which is tensioned or relaxed when the pulley 212 rotates. The pulley 212 is rotatably mounted by means of a bearing shaft 215 (shown schematically). The spiral spring device 211 also surrounds the bearing shaft 215 and is rigidly connected to the pulley 212 at a first end piece 2111 and directly or indirectly to the bearing shaft 215 at a second end piece 2112. The bearing shaft 215 is preferably rigidly connected to the housing 210.

[0081] When the pulley 212 rotates as the pull cable 22 is extended, the first end piece 2111 of the spring device 211 is guided around the bearing shaft 215, while the second end piece 2112 of the spring device 211 is held firmly in place. As soon as the pull cable 22 is released, the pulley 212 is rotated back by the tensioned spring device 211. If, for example, the coupling element 221 at the end of the pull cable 22 is hooked onto a retaining element 72 at the front end position S1 and the mounting profile 14 is inserted into the door compartment 18, the pull cable 22 is extended from the drive unit 21, the pulley 212 is rotated, and the spring device 211 is tensioned. The mounting profile 14 can then be locked in place with the locking device 95 when it reaches the rear end position S2.As soon as this locking mechanism is released, the pulley 212 is rotated back by the spring device 211, the pull cable 22 is retracted, and the mounting profile 14 is moved from the rear end position S2 to the front end position S1. A door 11 connected to the mounting profile 14 is therefore automatically extended from the door compartment 18.

[0082] The pull rope 22 is adjusted by means of the first adjusting device 3 according to Fig. 4 and preferably by means of the second adjusting device X3 according to Fig. 5 as required, it is pulled out of the drive device 2 in order to tension the spring device 211.

[0083] Fig. 4 The sliding device 10 of Fig. 2 with the upper guide carriage 5 and the drive device 2 according to Fig. 3 The mounting profile 14 is displaceable between the front end position S1 and the rear end position S2. The front end position S1 is reached when the stop element 53 of the guide carriage 5 strikes the stop damper or stop buffer 78 on the front stop device 7, which is preferably adjustable to set the front end position S1. The mounting profile 14 is preferably pulled by the drive device 2 over the entire travel path from the rear end position S2 to the front end position S1.

[0084] The pull rope 22 is guided from the drive device 2 via a first deflection pulley 231 and further deflection pulleys 232 and 233 to a first adjusting device 3, which is mounted on the upper front stop device 7. As shown below with reference to Fig. 5 As described, the first deflection pulley 231 can be part of an optional second adjusting device X3, which is intended, for example, for the coarse adjustment of the pretension of the drive device 2. For this purpose, the first deflection pulley 231 is slidably and lockably mounted along the mounting profile 14, as symbolized by a dashed arrow. By moving the first deflection pulley 231, the length of the path along which the pull rope 22 runs can be lengthened or shortened. The first adjusting device 3, on the other hand, contains a rotatable and lockable rope drum 33 (see Fig. 9 ), onto which the far end of the pull rope 22 can be wound. A screwdriver T is shown, which is inserted into the first adjusting device 3 at the front to loosen the rope drum 33 and rotate it if necessary.

[0085] The first adjusting device 3 is explained in more detail below with reference to the further drawings.

[0086] The preferably provided holding device 4, which comprises two holding cables 421, 422, is described below with reference to Fig. 5 described in more detail. However, with the inventive sliding device 10, any holding devices 4 can be used in all embodiments of the invention, by means of which a mounting profile 14 can be vertically aligned and slidably held.

[0087] Fig. 5 The sliding device 10 of Fig. 2 with the holding device 4 of Fig. 4 and with the mounting profile 14, which is connected to the drive device 2, from which the pull rope 22 is guided via a second adjusting device X3, which includes a first deflection pulley 231, and via a second deflection pulley 232 to a holding element 72, which is held on the upper front stop device 7. As already described in Fig. 4 As shown, the front stop device 7 can additionally be provided with the first adjustment device 3, as shown in Fig. 5 It is shown symbolically.

[0088] The second adjusting device X3 comprises a deflection unit X33, which is slidable and lockable along the mounting profile 14 and is equipped with the first deflection roller 231. The deflection unit X33 is positively engaged in a guide channel 141 of the mounting profile 14 and is slidable along it. It can be locked at a suitable location, preferably by means of a locking device such as a screw X32, either by frictional engagement and / or positive engagement. The locking device can also be designed as a detent device and, for example, have a detent tongue connected to the deflection unit X33, which can engage in a detent or toothing provided along or incorporated into the mounting profile 14.

[0089] By moving the deflection unit X33 along the mounting profile 14, the path from the pulley 212 to the second deflection pulley 232 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 in the drive device 2, and pre-tensions the spring device 211 accordingly. This adjustment can be easily made in just a few steps.

[0090] Fig. 5 Figure 1 also shows the preferably provided holding device 4, which comprises two holding cables 421, 422. The upper stop device 7 is connected to the front of the upper guide rail 15 and the lower stop device 8 is connected to the front of the lower guide rail 16 by a mounting beam 711, 811 and clamping screws 712 to the associated upper or lower guide rail 15, 16.

[0091] The upper front stop device 7 comprises the retaining element 72 for securing the pull cable 22, a cable connection device 74 for the second retaining cable 422, a rotary lever 75, the stop damper 78, and, if applicable, mounting means for mounting the first adjusting device 3. The rotary lever 75 serves to hold the mounting profile 14 in the front end position S1. The upper cable connection device 74 comprises a mounting channel with an adjoining recess into which an end piece of the upper retaining cable 422 can be inserted.

[0092] The second retaining cable 422 is held firmly by the cable connection device 74 of the upper stop device 7. The cable connection device 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 vertically aligned.

[0093] The holding device 4 comprises the first front 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 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 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 rope connection device 44.

[0094] Furthermore, the holding device 4 comprises the 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.

[0095] Fig. 6a shows the upper front stop device 7 and the associated first adjustment device 3 of Fig. 4 from the rear. In this embodiment, the first adjusting device 3 is not integrated into the stop device 7, but mounted on its underside. The pull cable 22 is guided via a third deflection pulley 233, which is held by the stop device 7, through the device body 71 of the stop device 7 and downwards into the housing 38 of the first adjusting device 3, which can be closed by means of a cover 39 (see Fig. 6b ).

[0096] Alternatively, the first adjusting device 3 can be integrated into the associated stop device 7 or 8. In these embodiments, the housing 38 of the first adjusting device 3 forms an integral part of the device body 71 or 81 of the associated stop device 7 or 8. The present embodiment, however, has the advantage that the first adjusting device 3 can be easily disassembled and / or manipulated and maintained, particularly in the case of sliding devices 10 that do not yet have a drive device 2.

[0097] Fig. 6b shows the upper stop device 7 and the associated first adjusting device 3 of Fig. 6a with the cover 39 detached from the housing 38 from the front, from which the first adjusting device 3 can be adjusted. The housing 38 of the first adjusting device 3, which is connected to the device body 71 of the stop device 7 by mounting elements and a connecting element 372, such as a connecting screw or a press pin, comprises a housing chamber 380 in which the rotatable adjusting element or the rope drum 33 rotates about the drum axis x (see Fig. 7a ) is rotatable and displaceable by a required amount along the drum axis x.

[0098] The traction cable 22 is guided over the third deflection pulley 233 to the cable drum 33 and connected to it. In this preferred embodiment, the cable drum 33 includes a retaining element 339 with which the end piece 221 (see Fig. 3 ) of the traction cable 22. The end piece 221 is, for example, a coupling rod or a coupling anchor, which preferably can be guided through a coupling channel 338 in the cable drum 33 and connected to the retaining element 339. Preferably, the retaining element 339 is designed as a recess in which the end piece 221 can be anchored (see Fig. 7a ).

[0099] At the front, the cable drum 3 is preferably integrally connected to a tool coupling element 31, which is arranged coaxially to the drum axis x. At the rear, the cable drum 33 is rotatably and slidably held by a bearing bushing 34 along the drum axis x. The cable drum 33 is, on one side, by means of the tool coupling element 31, in a tool chamber 3801 of the housing 38 (see Fig. 7b ) and on the other hand rotatably and slidably mounted in the bearing bushing 34 (see Fig. 8 ).

[0100] Furthermore, locking elements 32 are provided on the front side of the rope drum 33, which are connected to at least one counter element 383 (see Fig. 7b ) can interact on an inner wall of the housing 38 to prevent the adjusted rope drum 33 from rotating automatically. To adjust the rope drum 33, the locking elements 32 of the rope drum 33 and the at least one counter element 383, which is provided in a locking chamber 3802 of the housing 38, must be engaged (see Fig. 7b ) are decoupled from each other.

[0101] The bearing bushing 34 is preferably held immovably and non-rotatably in the housing 38. A drum spring 35 pushes the cable drum 33 away from the bearing bushing 34 with a force vector parallel to the drum axis x, allowing the locking elements 32 provided on the front of the cable drum 33 to interact with the counter element 383. The cable drum 33 must therefore be displaced axially against the bearing bushing 34 so that the locking elements 32 are decoupled from the counter element 383, allowing the cable drum 33 to be rotated and the preload on the drive device 2 to be adjusted (see also Fig. 7a ).

[0102] After a tool is coupled to the tool coupling part 31, the cable drum 33 is first moved axially against the bearing bushing 34 to decouple the locking elements 32 from the counter element 383. The cable drum 33 is then rotated, if necessary, to wind up the pull cable 22 and adjust the preload on the drive device 2. After the preload is adjusted, the tool is retracted, causing the cable drum 33 to be moved axially back by the drum spring 35. The locking elements 32 and the counter element 383 then re-engage, and the cable drum 33 is fixed with the adjusted preload.

[0103] The figures of a "snail" and a "hare" on the front of the first adjusting device, next to the tool coupling part 31, symbolize that by rotating the rope drum 33 counterclockwise the preload can be increased and by rotating the rope drum 33 clockwise the preload can be reduced in order to adjust the desired acceleration and displacement speed of the mounting profile 14.

[0104] A locking element in the form of a mounting fork 399 is inserted into the cover 39, which is designed to complement the housing 38. This locking element allows the cable drum 33, the bearing bushing 34, and the drum spring 35 to be fixed to the cover 39 and easily mounted. The mounting fork 399 presses the drum spring 35 against the cable drum 33 and holds it in position, so that the assembled device 33, 34, 35 can be conveniently inserted into the housing 38. To operate the first adjusting device 3, the mounting fork 399 is removed and the drum spring 35 is activated. It then preferably rests against a part, such as a retaining wall 382 of the housing 38 (see figure). Fig. 7b ).

[0105] Fig. 6c shows the front stop device 7 and the associated first adjustment device 3 of Fig. 6a in a sectional view.

[0106] It is shown that the third deflection roller 233 is rotatably mounted in the fixture body 71 of the stop device 7. The stop buffer 78, which has a buffer body 781, is axially adjustable in the fixture body 71 by means of an adjusting screw 782.

[0107] The transfer channel 338 is visible from the cable drum 33, through which the end piece 221 of the pull cable 22 is guided. The mounting fork 399 has not yet been removed, which is why the drum spring 35 is not yet activated.

[0108] The bearing bushing 34 has a bushing sleeve 341 and is firmly anchored in the housing 38 of the first adjusting device 3 by a bushing anchor 342. A slide 36 is provided inside the bushing sleeve 341, which, when the cable drum 33 rotates, moves axially between a rear end stop, preferably formed by the rear side wall 381 of the housing 38 or a part of the bearing bushing 34, and a front end stop, preferably formed by a part of the cable drum 33, preferably via a threaded rod 334 connected to the cable drum 33 (see Fig. 8 ) is movable. The number of revolutions of the rope drum 33 in one direction and the other is therefore limited.

[0109] Fig. 6d shows the upper stop device 7 and the associated first adjusting device 3 of Fig. 6b in a sectional view.

[0110] A space is kept free between the housing 38 and the device body 71, into which the locking lever 75 (see Fig. 5 ) can be used (not shown), which is supported by the partially exposed lever spring and can be fixed by means of a screw. The mounting profile 14 can be fixed to the stop device 7 by means of this locking lever.

[0111] Fig. 7a The first adjustment device 3 of Fig. 6b without cover 39. It is shown that the rope drum 33 has a winding body 333, to which a first drum wall 331 is attached at the front and a second drum wall 332 at the rear, and which is provided with the transfer channel 338 and the molded retaining element 339.

[0112] It is further shown that the bearing bushing 34 has a bushing slot 3410 on the side facing the bushing sleeve 341. This slot is exposed to the outside in a first portion and concealed in a larger cylindrical portion. A slide wing 361 of the slide 36 is guided in the bushing slot 3410 such that the slide 36 is axially displaceable but not rotatable. The slide 36 is displaceable through the entire bushing sleeve 341 between the second drum wall 332 of the cable drum 33 and the end-face side wall 381 of the housing 38. Once the slide 36 has reached the second drum wall 332 on one side or the side wall 381 of the housing 38 on the other, the cable drum 33 can no longer be rotated. Therefore, the preload of the drive device 2 is adjustable only within a predetermined range, which is preferably defined by the second adjusting device X3.

[0113] Fig. 7a Figure 33 further shows that four locking elements 32 are arranged at equal intervals offset from one another on the first drum wall 331. The locking elements 32 are wing-shaped or rib-shaped and extend radially outwards concentrically to the drum axis x and are preferably integrally connected to the tool connection part 31 and / or the cable drum 33. The cable drum 33 can therefore be adjusted and locked with a quarter turn. After the cable drum 33 has been adjusted and locked, it is held rotationally fixed by the tensile force of the pull rope 22 in one direction of rotation and by the locking elements 32 and the counter element 383 in the other direction of rotation.

[0114] The drum spring 35 rests against the second drum wall 332, which is still held by the mounting fork 399 and is not activated.

[0115] Fig. 7a further shows a bolt 371 by means of which the cover 39 can be fixed, and the connecting element 372 by means of which the housing 38 of the first adjusting device 3 can be connected, for example, to the device body 71, 81 of the upper or lower stop device 7, 8.

[0116] Fig. 7b The housing 38 shows the adjusting device 3 of Fig. 7a With regard to the housing chamber 380. The housing chamber 380 comprises a tool chamber 3801, in which the tool coupling part 31 is rotatably and slidably held, a locking chamber 3802, into which a counter element 383 projects, and a drum chamber 3803, in which the cable drum 33 is rotatably and slidably held, as well as a bushing chamber 3804 and an anchor chamber 3805, in which the bearing bushing 34 is held. At the transition between the drum chamber 3803 and the bushing chamber 3804, a retaining wall 382 results, against which the drum spring of 35 rests after activation or after removal of the mounting fork 399.

[0117] Fig. 8 Figure 3 shows an exploded view of the rope drum 33, the bearing bushing 34, the drum spring 35, the slide 36, which are aligned along the drum axis x, and the cover 39. The rope drum 33 comprises the winding body 333, the first drum wall 331, which is integrally connected to the locking elements 32 and the tool coupling part 31, and the second drum wall 332, which is integrally connected to a threaded rod 334 that is coaxially aligned with the drum axis x.

[0118] The bearing bushing 34 is traversed from front to back by a bushing channel 340, which is widened on opposite sides by the bushing slots 3410. The bushing channel 340 runs through the bushing armature 342, which is why the housing 38 forms an end stop. In preferred embodiments, however, the bearing bushing 34 forms this end stop, for example, by the bushing armature 342 forming a closed plate that closes off the bushing channel 340 on one side. In this embodiment, the slide 36 can therefore only be inserted into the bearing bushing 34 from the side of the bushing channel 340 that faces the cable drum 33.

[0119] The slide 36, which has a threaded bore 360 ​​and two outwardly directed slide wings 361 opposite each other, is screwed onto the threaded rod 334. The threaded rod 334, fitted with the slide 36, is inserted into the bushing channel 340 such that the bushing wings 361 are guided in the bushing slots 3410. The slide 36 can also first be inserted into the bushing channel 340 from one side or the other and then connected to the threaded rod 334 of the cable drum 33.

[0120] The cover 39 is designed to complement the housing 38 and comprises a tool chamber cover part 391, a locking chamber cover part 392, a drum chamber cover part 393, a bushing chamber cover part 394, and mounting openings 390 for inserting the mounting fork 399. During the assembly of the rope drum 33, the bearing bushing 34, and the drum spring 35, which is held by the mounting fork 399, the first drum wall 331 preferably rests against a wall section 395 that forms the transition between the armature chamber cover 392 and the drum chamber cover 393.

[0121] Fig. 9 The first adjustment device 3 of Fig. 4 during the adjustment process, in which the tool symbolized by an arrow is connected to the tool coupling part 31 and the cable drum 33 is moved against the bushing sleeve 34 and the drum spring 35 is compressed accordingly to disengage the locking elements 32 from the engagement with the counter element 383 (see Fig. 7b ) to release. In this position, the cable drum 33 can be rotated until the slide 36 encounters, on the one hand, a stop element of the bearing bushing 34 or the rear side wall 381 of the housing 38, or, on the other hand, the second drum wall 332 of the cable drum 33 at the front. After setting the desired preload of the drive device 2 or of the drive spring 211 therein, the tool is retracted. During this process, the cable drum 33 is pushed back by the drum spring 35 until the locking elements 32 engage again in the locking chamber 3802 and the cable drum 33 is locked.

[0122] Fig. 10 shows the auxiliary drive 9 of Fig. 2The auxiliary drive 9 comprises a housing 93 and at least one extendable piston 91, which is supported by a spring element 92 and rests against the stop device 90 after the mounting profile 14 has entered the door compartment 18. The spring element 92 of the auxiliary drive 9 is tensioned as soon as the mounting profile 14 moves towards the rear end position S2 within the door compartment 18. After reaching the rear end position S2, the spring element 92 of the auxiliary drive 9 is loaded and can assist the drive device 2 at the beginning of the extension of the mounting profile 14 towards the front end position S1.

[0123] 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 a stop plate 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 rear end position S2, 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.

[0124] Furthermore, damping devices 99 with damping pistons 991 are provided, which strike the stop plate of the stop device 90 as soon as the mounting profile 14 reaches the rear end position S2. Reference symbol list:
