Description

[Technical Field]

[0001] The present invention relates to a sliding door system having a sliding door with at least one activatable sealing device for closing a door opening, and to a buffer device for the sliding door system. [Background technology]

[0002] U.S. Patent No. 7,891,052 (B2) discloses a sliding door system having a carriage guided along a running rail that serves to hold a glass panel. The carriage is connected to the glass panel by a fixing means so that the upper edge of the glass panel can be accommodated within the cross section of the running rail. This allows the space between the glass panel and the running rail to be nearly sealed. In the case of sliding doors with thicker partition panels, for example made from wood, it is nearly impossible to fit the wooden panel within the cross section of the running rail.

[0003] US Patent No. 9,290,977 (B2) discloses a sliding door system having a carriage connected to a door panel that can be moved along a rail so that the door panel can be guided relative to the door frame in front of the door opening. This sliding door system requires a rail designed accordingly.

[0004] U.S. Patent Application No. 2011 / 126,471(A1) discloses a movable sealing device for a door or window, having a sealing rail and a sealing strip held therein, which can be lowered by a lowering mechanism. The lowering mechanism includes an actuating element that acts on a leaf spring connected to the sealing strip via an interconnected slide. By pressing the actuating element, the slide is actuated, the leaf spring is deformed, and the sealing strip is lowered. In this process, not only is the sealing strip moved downward, but the carrier profile is also moved toward the corresponding front surface, thus sealing against that surface. The actuating element protrudes from the sealing device and is pressed against the sealing device by the door frame when the door is closed. A second actuating button can be provided on the opposite end face of the door, so that the lowering mechanism can be operated from both sides of the door.

[0005] U.S. Patent Application No. 2019 / 128,054(A1) discloses a sliding door with a movable descending seal that includes an actuating element. The actuating element is operable by a transmission that is screwed to the sliding door and an activation unit that is screwed to the door frame. The transmission includes a follower that can cooperate with the activation unit and a pivot arm connected to the follower that can cooperate with the activation unit when the sliding door is moved to an end position. In this operation, the follower is guided across the contact surface of the activation unit and rotated together with the pivot arm, thereby pressing the actuating element against the descending seal. This device ensures accurate positioning and assembly of the activation unit.

[0006] It should be noted that sliding doors are usually equipped with a mounting device that is connected to the associated carriage. The mounting device is often integrated into the door recess, which means that the sliding and running technology are located next to each other and can thereby interfere with each other during installation, maintenance, and / or adjustment.

[0007] European Patent No. 0,818,598 (B1) and U.S. Patent No. 9,341,011 (B2) disclose mounting devices with mounting rails that are inserted into recesses in the upper surface of the door leaf of a sliding door. In each mounting rail, a mounting unit is axially slidable and lockable. The mounting unit is connected by a connecting screw to the carriage body of a carriage guided in a running rail.

[0008] In the device of EP 0,818,598 (B1), the mounting unit for adjusting the height of a sliding door is disengaged and removed from the mounting rail until the connecting screw at the front of the end face of the door leaf can be grasped and turned by a tool.

[0009] In the device of U.S. Pat. No. 9,341,011 (B2), the mounting unit is provided with an adjustment screw arranged parallel to the longitudinal axis of the running rail, by means of which the slide holder, on which the slide is slidably mounted along the guideway, can be displaced axially. When the slide holder is moved axially, the slide connected to the adjustment screw is moved upward or downward along the guideway. By turning the adjustment screw, the sliding door can therefore be raised or lowered. For this adjustment, it is not necessary to remove the mounting unit from the mounting rail. However, access to the adjustment screw must be maintained.

[0010] EP 0,818,598 B1 further discloses a shock absorber with a damping element and a locking element. The shock absorber elastically stops the sliding door at its end and then holds it. The shock absorber can be precisely positioned so that the sliding door stops in the closed position, i.e., exactly in front of the door opening to be closed.

[0011] Sliding door systems therefore comprise several devices that allow the travel path as well as the installation height of the sliding door to be adjusted. Additional drives can be provided, by means of which the sliding door can be moved automatically. With the additional installation of a movable sealing device, additional requirements for the adjustment of the sliding door system must be met in order for the sealing device to be precisely actuated in the closed position. The individual adjustment devices or device parts of the travel technology and sealing technology must be matched to each other in this respect, which can be a great effort.

[0012] Furthermore, it is necessary to ensure that the device and the parts used do not interfere with each other, as this may interfere with the assembly, maintenance and / or adjustment of the individual parts of the sliding door system. [Prior art documents] [Patent documents]

[0013] [Patent Document 1] U.S. Patent No. 7,891,052(B2) [Patent Document 2] U.S. Patent No. 9,290,977(B2) [Patent Document 3] U.S. Patent Application No. 2011 / 126,471(A1) [Patent Document 4] U.S. Patent Application No. 2019 / 128,054(A1) [Patent Document 5] European Patent No. 0,818,598(B1) [Patent Document 6] U.S. Patent No. 9,341,011(B2) Summary of the Invention [Problem to be solved by the invention]

[0014] It is therefore an object of the present invention to provide an improved sliding door system comprising a sliding door, the sliding door comprising a movable sealing device, a sliding door for such a sliding door system, and an improved buffer device for the sliding door system.

[0015] Sliding door systems should have a simple and compact design and should be installable, maintainable and adjustable with little effort.

[0016] For example, parts of the sealing technology, such as the sealing device and the elements for actuating it, between the buffer device and the assembly device for connecting the carriage to the sliding door, and parts of the running technology, such as the carriage guided in the running rail, should interact advantageously and be optimally adapted to each other.

[0017] The parts of the travelling technology and the parts of the sealing technology should be able to be used and / or interact without interfering with each other, in particular the elements of the travelling technology and the sealing technology should advantageously be able to be assembled, disassembled and adjusted.

[0018] Furthermore, the interaction between the fixed parts of the travel technology and the fixed parts of the sealing technology should be able to be brought about optimally, virtually without mutual adjustments and adaptations.

[0019] The sliding door should be held as close as possible to the running rail, so that the movable sealing device has to seal the smallest possible gap.

[0020] Furthermore, the sealing device should be movable. A movable sealing device should comprise a sealing strip that can be removed upwards or downwards by any mechanism.

[0021] The components of the sliding door system should be small, inexpensive to manufacture, and easy to assemble. [Means for solving the problem]

[0022] This problem is solved by means of a sliding door system according to claim 1, a sliding door according to claim 11 and a buffer device according to claim 12. Advantageous embodiments of the invention are specified in the further claims.

[0023] The sliding door system comprises a sliding door, The sliding door is displaceable along a running rail to a closed position against an activation member disposed in a fixed position; The sliding door is equipped with a door leaf, The sliding door comprises at least two carriages, each comprising a carriage body and a running element, connected to a door leaf, held in a running rail, and displaceable parallel to the longitudinal axis of the running rail; The sliding door is equipped with a movable sealing device comprising a removable sealing strip and an actuating element; The sliding door is provided with a transmission device having a transmission element; The triggering member and transmission device are arranged so that when the sliding door is in the closed position, force can be transmitted from the triggering member through the transmission element to the operating element to push out the sealing strip.

[0024] According to the present invention, a stationary shock absorber is provided for stopping the sliding door in the closed position and includes an actuating member.

[0025] Preferably, the buffer device is disposed within a cross section of the running rail. The running rail is preferably disposed on the upper surface of the sliding door, so that the door leaf is suspended on a carriage that can be moved within the running rail. When the sliding door is in the closed position, the door opening can preferably be sealed.

[0026] The mutual alignment of the travel and sealing technology is therefore carried out with reference to the damper, which needs to be positioned precisely. On the other hand, the mutual alignment of the damper and the actuating member is omitted, leading to an overall reduction in the complexity of the sliding door system. If changes are made to the sliding door system that require a new adjustment, only the damper needs to be readjusted.

[0027] The shock absorber comprises a shock absorber body which holds or comprises at least one damping element or damper and / or locking element. Preferably, the shock absorber comprises at least one central damping element or central damper. Alternatively, the shock absorber may be provided with lateral damping elements or lateral dampers on each side. In a further preferred embodiment, lateral dampers and a central damper may be provided in combination.

[0028] The damping elements, lateral dampers and / or central damper may be made of an elastic material such as rubber. The damping elements, lateral dampers and / or central damper may also be mechanical dampers such as spring elements, pneumatic dampers, hydraulic dampers, oil dampers or magnetic dampers with magnetic elements.

[0029] The locking element of the shock absorber preferably comprises at least one locking arm by means of which the carriage can be held. Preferably, the locking element is fork-shaped and has two locking arms oriented toward the opposite carriage. When the carriage enters, the carriage is preferably coupled to the shock absorber, whereby the at least one locking arm elastically covers and holds one and / or part of the running wheels of the carriage body.

[0030] The carriage may be mechanically or magnetically mounted in the running rail. The running elements may be rollers, wheels, sliding elements, or ferromagnetic or permanent magnetic elements.

[0031] The actuating member can be detachably connected to the damping body, as can the at least one damper or locking element. In a preferred embodiment, the actuating member is an integral part of the damping body. The damping body can advantageously be provided with the actuating member. For example, the damping body is manufactured in one piece, thereby eliminating the need to manufacture the damping body and the actuating member separately.

[0032] The shock absorber is preferably stressable within the running rail so that it can be moved and fixed or stressed into a suitable position.

[0033] The running rail has a head and at least one side on which the legs are provided. Preferably, the running rail has a C-shaped or U-shaped profile with two sides connected to each other at one end by a head and connected to each other at the other end by opposing legs. The leg or legs have a running surface on their upper surface on which the running elements of the carriage are supported.

[0034] Preferably, the buffer device or buffer body comprises a leg element that is supported on the leg of the running rail. In this embodiment, the buffer device is preferably provided with at least one threaded hole for a counter screw, which is screwed into the head of the running rail and presses the buffer device or buffer body against the leg of the running rail, thereby fastening it.

[0035] Between the leg elements of the buffer device, there is preferably an activation channel in which an activation member is provided and which is suitable for partially receiving the transmission element. The transmission element, possibly a transmission lever, can therefore enter the activation channel and cooperate there with the activation member. This design of the buffer device allows the sliding door to be raised further relative to the running rail, since the part of the transmission element exposed above the sliding door can enter the buffer device, preferably also into the cross section of the running rail. By raising the sliding door to its maximum height relative to the running rail, the gap between the upper edge of the sliding door and the lower edge of the running rail, which needs to be closed by the movable sealing device, is reduced. It is therefore easier to use movable sealing devices or other optimized sealing devices.

[0036] In a preferred embodiment, the actuation member is designed as a ramp extending along a straight or preferably inclined curve relative to the longitudinal axis of the running rail, however, the actuation member can also have other geometric shapes that allow the transmission element to rotate.

[0037] In a preferred embodiment, the ramp extends along a curve whose steepness is selected so that the rotational speed of the transmission element, designed as a transmission lever, is continuously reduced from a high value at a constant operating speed of the sliding door. That is, when driven along the ramp, the transmission lever is first rotated rapidly to quickly raise the sealing strip. The elastic sealing element of the sealing strip is deformed, and shortly before or after it comes into contact with the running rail, the rotational speed is correspondingly reduced, so that the sealing strip is pressed against the running rail in a controlled manner. The cross section or gradient of the curve or path of the ramp is preferably selected to provide the minimum load on the device parts used and the optimum sealing.

[0038] The transmission element of the transmission device is preferably a transmission lever with a first lever portion arranged for cooperation with the actuating member and a second lever portion arranged for cooperation with the actuating element of the sealing device. The two lever portions may be of different shapes and dimensions and may be oriented differently. Preferably, both lever portions are arranged parallel or at an angle to each other. The first lever portion is typically longer than the second lever portion and, for example, protrudes from a door recess in the door leaf.

[0039] Sliding doors may have door leaves made of glass or wood or another material.

[0040] Preferably, the door leaf is provided with a mounting channel or recess in its upper surface, preferably extending from one end face of the door leaf to the other end face and defined on one or both sides by the remainder of the door leaf.

[0041] Preferably, a door recess is provided; a) a mounting device is arranged in the door recess, the mounting device comprising a mounting unit connected to one of the carriages and removably held in a mounting rail connected to the door leaf; b) a movable sealing device is disposed in the door recess adjacent to the mounting device; c) A transmission device is arranged in the door recess, in front of the mounting device and the movable sealing device.

[0042] Preferably, the transmission device comprises a lever holder for holding a lever shaft on which the transmission element, possibly a transmission lever, is rotatably mounted, the lever holder being preferably removably held by a mounting base which is connected to the door leaf. The lever holder and the mounting base therefore preferably comprise corresponding locking elements and corresponding latching elements.

[0043] This embodiment of the transmission has several advantages: To mount the transmission, the mounting base can first be connected to the door leaf, for example by screwing it in place, after which the lever holder can be inserted.

[0044] Before inserting the lever holder, the mounting unit of the mounting device is inserted into the mounting rail, which is also pre-attached or, if appropriate, screwed to the inside of the door recess. Preferably, the mounting bar is fixed to the inside of the door recess, for example, by means of self-tapping mounting screws or wood screws. The mounting rail can then be fixed by means of screws that are screwed into threaded holes in the mounting bar. This has the advantage that mounting bars, which preferably have several mounting holes, can be attached in a particularly stable manner. The mounting rail can then be connected to the mounting bar in a simple manner, for example, using only two mounting screws.

[0045] The mounting unit is inserted into the mounting rail before the lever holder is connected to the pre-assembled mounting base. The lever holder can also be removably connected to the mounting bar.

[0046] If the mounting unit needs to be removed from the mounting rail, for example for maintenance or adjustment of the sliding door, the lever holder of the transmission is first unlocked and removed using a handle or with a tool. The mounting unit can then be pulled out of the mounting rail via the mounting base in front of the front face of the door leaf. The mounting unit can then be pushed back into the mounting rail, and the lever holder can be reconnected to the mounting base using the handle.

[0047] Since the mounting base is mounted without the lever holder and transmission lever, the area of ​​the mounting base that is below the lever holder after the lever holder is mounted can be used to insert the mounting screws. This means that no mounting flanges are needed outside the area of ​​the lever holder, and therefore the lever holder can be reduced to the dimensions of the mounting base. The transmission therefore occupies the smallest possible space. This allows the transmission to be mounted close to the front of the door leaf in a stable manner, preferably leaving space for the cover.

[0048] The invention is explained in more detail below with reference to the drawings. [Brief explanation of the drawings]

FIG. 8c shows the transmission lever 61 and the lever holder 62 of FIG. 8b detached from each other. [Figure 9] 2 is a diagram of the sliding door system 1 of FIG. 1 in a further preferred embodiment with a preferably designed shock absorber 9 and a preferably designed mounting device 4. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0050] FIG. 1 shows a sliding door system 1 of the present invention having a sliding door 11 of the present invention, which can close a simple door opening 10 or a door opening 10 surrounded by a door frame 12. The sliding door 11 comprises a door leaf 111, the front quarter of which is cut away to partially expose a movable sealing device 8 disposed in a door recess 110 on the upper surface and preferably also on the lower surface. A first mounting device 4 is also shown on the upper surface of the sliding door 11, which is connected to the door leaf 111 on the one hand and to the first carriage 3 on the other hand. A second mounting device 4, which is connected to the door leaf 111 on the one hand and to the second carriage 3 on the other hand, is covered by the rear side of the door leaf 111.

[0051] The two carriages 3 are guided within the running rail 2 and can be moved along the running rail 2 until the first carriage 3 strikes an inventive shock absorber 9 mounted within the running rail 2. The left portion of the running rail 2 is cut away along its longitudinal axis to show the shock absorber 9.

[0052] By means of the buffer device 9, the sliding door 11 is elastically stopped in the front end position or closed position of the door opening 10 and is preferably fixed by a locking element 98 (see FIG. 3), so that the sliding door 11 is held in a defined position, i.e. the closed position, and cannot be automatically retracted. Only by applying force can the sliding door 11 be released from the locking element 98 and retracted again.

[0053] The movable sealing device 8 is also actuated by an actuating member 911 (see Figure 3) connected to the buffer device 9, and the movable sealing device 8 can seal the gap between the upper edge of the sliding door 11 and, for example, the lower edge of the running rail 2.

[0054] A movable sealing device 8 optionally provided on the underside of the sliding door 11 can also be activated when the closed position is reached, as known from the prior art described at the outset.

[0055] Conventional seals 18 are preferably provided on the vertical members 121, 122 of the door frame 12 to seal the gap between the sliding door 11 and the vertical members 121, 122 when the sliding door 11 reaches the closed position.

[0056] In the closed position of the sliding door 11, the door opening 10 is therefore completely closed and sealed in this preferred embodiment.

[0057] 2a shows the front of the sliding door 11 of FIG. 1 facing the buffer device 9, which has a door recess 110 on the upper surface of the door leaf 111, and in which a transmission device 6 for actuating the movable sealing device 8 is arranged on the front side, behind which, in line, the movable sealing device 8 and the first mounting device 4 are arranged, and the mounting device 4 is connected to the first carriage 3 of FIG. 1 by a connection part 35, for example a connecting screw. The buffer device 9 has been removed from the running rail 2 to reveal the first carriage 3.

[0058] The running rail 2 comprises two sides 22 connected to each other at the top by a head 21 and connected to each other at the bottom by legs 23 opposite each other.

[0059] The carriage 3 comprises a carriage body 31 which carries on both sides running elements 32 which are supported on the legs 23 of the running rail 2. Opposite the damper 9, the carriage body 31 further comprises a stop element 311 which abuts against one or more damping elements of the damper 9 when the closed position of the sliding door 11 is reached.

[0060] The transmission device 6 is mounted directly adjacent to the front surface of the door leaf 111 and comprises a transmission element, in the embodiment of a transmission lever 61, a lever holder 62 and a mounting base 63. The lever holder 62 comprises a locking plate 621 detachably mounted on the mounting base 63 and a lever shaft 622, by means of which the transmission lever 61 is rotatably supported. The transmission lever 61 comprises a first lever part 611 capable of cooperating with the buffer device 9 and a second lever part 612 capable of cooperating with the actuating element 82 of the movable sealing device 8. Both lever parts 611, 612 are adjacent to each other and are dimensioned such that interaction with the actuating element 82 and the buffer device 9 occurs as soon as the sliding door 11 is moved to the closed position.

[0061] The mounting base 63 includes a locking and latching element 631 by means of which the lever holder 62 is releasably locked. The lever holder 62 is provided with a locking recess 620, into which the latching element 631 can engage. The locking recess 620 also forms a window through which a tool, for example a screwdriver, can be inserted to press down the latching element 631 and release it from the lever holder 62. The lever holder 62 can therefore be detached from the mounting base 63 with a single movement of the hand.

[0062] The movable sealing device 8 comprises a housing 83 in which a removable sealing strip 81 and a removal mechanism 84 (see FIG. 5 a ) that can be actuated by an actuation element 82 are arranged.

[0063] In addition to the movable sealing device 8, a mounting device 4 is arranged inside the door recess 110 for each carriage 3. The mounting device 4 shown comprises a mounting rail 42 onto which a mounting unit 41 can be slid and locked in one or more positions by means of a latching element such as a latching tongue 411.

[0064] 2b shows the front of the sliding door 11 of FIG. 2a, depicting the rear side of the mounted shock absorber 9, which is stressed in the cross section of the running rail 2 by at least one counter screw 99. The shock absorber 9 comprises a shock absorber body 91 having a leg element 912, which is supported on the leg 23 of the running rail 2. Inside the shock absorber body 91, a counter screw 99 is held in a threaded hole. By turning this counter screw 99 relative to the head 21 of the running rail 2, the shock absorber body 91 is compressed and stressed against the leg 23 of the running rail. The shock absorber 9 can thus be inserted into the running rail 2, moved into a suitable position, and fixed in place by tightening the counter screw 99.

[0065] Furthermore, the buffer body 91 comprises an actuating member 911 which can interact with the first lever part 611 of the transmission lever 61 when the sliding door 11 or the first carriage 3 is moved relative to the buffer device 9. During this movement, the transmission lever 61 is rotated, the second lever part 612 is guided relative to the actuating element 82, the ejection mechanism of the sealing device 8 is activated, and the sealing strip 81 is guided against the underside of the running rail 2, thereby sealing the gap between the upper edge of the door leaf 111 and the lower edge of the running rail 2. At least the top part of the sealing strip 81 is preferably elastic, so that it presses evenly against the underside of the running rail 2. The movement of the sealing strip 81 during the closing process is represented by arrow symbols.

[0066] It can be seen that the actuating member 911 is virtually completely integrated into the shock absorber 9 and therefore does not require any additional space. The shock absorber 9 according to the invention can therefore be manufactured with the dimensions of a conventional shock absorber 9.

[0067] Figure 3 shows the sliding door system 1 having the sliding door 11 of Figure 1 in a space with a door leaf 111 shown diagrammatically, a first carriage 3 guided in a running rail 2 and facing a buffer device 9, a first mounting device 4, a movable sealing device 8 and a transmission device 6. The running rail 2 is cut along its longitudinal axis.

[0068] In the preferred embodiment, the shock absorber 9 is shown in longitudinal section along its central axis. The section extends through two threaded holes or threaded channels 990 in which counter screws 99 are rotatably held. The threaded channels 990 are open at the bottom so that tools can be applied to the counter screws 99 from below in order to rotate them relative to the head of the running rail 2 shown in cross section.

[0069] On its underside, the buffer body 91 is provided with an actuating member 911 designed as a ramp. The actuating member 911 is therefore completely integrated into the buffer body 91 and therefore does not require any additional space. For this purpose, the buffer body 91 preferably has an actuating channel 910 between the leg elements 912, into which the first lever part 611 of the transmission lever 61 can enter. When the sliding door 11 is moved further towards the buffer device 9, the transmission lever 61 is rotated clockwise, thereby guiding the second lever part 612 towards the actuating element 82 of the movable sealing device 8. The actuating channel 910 therefore allows the transmission lever 61 to be at least partially accommodated therein, so that the sliding door 11 can be raised almost up to the running rail 2, with only a minimal gap between them.

[0070] At the front, the shock absorber 9 comprises two, only one of which is shown, side dampers 95 and a central damper. The central damper 96 is made from a resilient material such as rubber or plastic. The side dampers 95 preferably comprise pistons and cylinders that can be moved relative to each other.

[0071] Furthermore, the buffer device 9 comprises a preferably elastic locking element 98 on its upper surface, which is mounted on the rear side of the buffer body 91 and can be elastically rotated relative to the buffer body 91 by means of a symbolically shown screw 981. The longitudinally cut locking element 98 also comprises two elastic locking arms 982 (only one is shown) which are oriented towards the opposing first carriage 3. The two elastic locking arms are each designed to elastically engage and hold one of the rollers 32 of the carriage 3.

[0072] Figure 3 further shows a movable sealing device 8, which will be described in more detail below with reference to Figures 5a and 5b, a mounting device 4, which will be described in more detail below with reference to Figures 4, 7a and 7b, and a transmission device 6, which will be described in more detail below with reference to Figures 8a, 8b and 8c.

[0073] FIG. 4 shows the sliding door 11 of FIG. 3, depicting the opposing front faces of the door leaf 111. The mounting device 4 is arranged behind the transmission device 6 in the door recess 110. A mounting rail 42, which is rigidly connected, e.g., screwed, to the door leaf 111, comprises a mounting channel 420 defined by side elements having locking flanges 421 oriented toward each other. The mounting unit 41 is inserted into the mounting channel 420 and is held by the locking flanges 421. The connecting screw 35 protrudes between the locking flanges 421 and is screwed into the carriage body 31 of the carriage 3.

[0074] The locking flange 421 also comprises a locking countersink 4210 into which the latching tongue 411 of the mounting unit 41 engages. By lifting the latching tongue 411, the mounting unit 41 can be released and moved inside the mounting rail 42 to another latching position.

[0075] 2a, it has already been explained that the lever holder 62 can be unlocked and removed with virtually one hand movement. If the carriage 3 needs to be inspected or adjusted, the locking connection between the mounting unit 41 and the lever holder 62 is released, after which the mounting unit 41 can be extended with the carriage 3. After maintenance or adjustment of the carriage 3, the mounting unit 41 is pushed back onto the mounting rail 42 and locked in place. The lever holder 62 is then reconnected to the mounting base 63 by means of the handle.

[0076] Figure 5a shows the movable sealing device 8 of Figure 4 with the ejection mechanism 84 shown diagrammatically before actuation by the transmission lever 61 symbolised by the transmission 6. In a preferred embodiment, the ejection mechanism 84 comprises several leaf springs 141 connected to the actuating element 82 by means of a push rod 842. By moving the actuating element 82, the leaf springs 141 are bent such that the sealing strip 81, preferably comprising an elastic end element 811, is lifted and elastically pressed against the underside of the running rail 2.

[0077] FIG. 5b shows the movable sealing device 8 of FIG. 5a after actuation by the symbolically indicated transmission lever 61 guided relative to the actuating device 82 and activation of the ejection mechanism 84, by which the sealing strip 81 has been lifted.

[0078] 1 from the side, with a locking element 98, which is mounted on the rear side to the buffer body 91 by an anchor part 981 and which has two elastic anchor arms 982 on the front side, which are bent so as to be able to engage on and respectively hold the running wheels 32. The actuating member 911 is integrated and embedded in the buffer body 91, so that only its lower part is visible.

[0079] FIG. 6b shows the shock absorber 6 of FIG. 6a from the front. It can be seen that the two lateral dampers 95 are arranged symmetrically around the central damper 96. On the top side, the two locking arms 982 and one of the counter screws 99 are visible. On the bottom side of the shock absorber 9, the leg elements 912 of the shock absorber body 91 are shown, between which the actuation channel 910 is recessed into the shock absorber body 91. The channel bottom of the actuation channel 910 forms an actuation member 911, preferably in the form of a bevel. A hole through which a screwdriver can be inserted to turn the counter screw 99 and the fixing screw 981 is inserted at the bevel 911, by which the locking element 98 is held and prestressed.

[0080] FIG. 6c shows an exploded view of the shock absorber 6 of FIG. 6a. The shock absorber body 91 is shown to have two side openings 915 for receiving the side dampers 95, a central opening 916 for receiving the central damper 96, and a locking protrusion 918 for locking the anchor element 981 of the locking part 98. Symbolically, the side dampers 95 are shown to have a piston 951, which is preferably connected to a piston rod 953 and slidably mounted in a damping cylinder 952. A viscous substance or medium, such as air, is contained in the damping cylinder 952, which is displaced by the piston 951. Preferably, the piston 951 is returned to its original position by an elastic element. The shock absorber body 91 is preferably made of plastic or metal.

[0081] 7a shows the mounting device 4 of FIGS. 3 and 4 with a mounting rail 42 in which a mounting unit 41 connected to the carriage 3 is held, the mounting rail 42 being supported in this preferred embodiment on a mounting bar 43. In the preferred embodiment, the mounting bar 43 is connectable to the door leaf 111 of the sliding door 11 in the door recess 110 and is preferably made of metal. To more easily connect the mounting rail 42 to the mounting bar 43, corresponding connecting elements 429, 439 are provided. The connecting elements 429, 439 ensure that the corresponding mounting holes and threaded holes of the mounting rail 42 and the mounting bar 43 are always coaxially aligned with each other.

[0082] Figure 7b shows the mounting device 4 of Figure 7a in an exploded view, with a longitudinal section through the mounting unit 41. The latch tongue 411 which is inserted into the latch recess 4210 in Figure 7a has an exposed end and is preferably elastic. The connecting screw 35 which is connected to the carriage body 31 of the carriage 3 is rotatably held in the connecting channel 410 of the mounting unit 41.

[0083] The mounting bar 43, which is separated from the mounting rail 42 in FIG. 7b, comprises mounting holes 430 and threaded holes 431. Self-tapping mounting screws 432 can pass through the mounting holes 430 to connect the mounting bar 43 to the door leaf 111. The mounting rail 42 can then be connected to the mounting bar 43 by inserting mounting screws 423 into the threaded holes 431 in the mounting bar 43 and through the mounting holes 4230 in the mounting rail 42. This has the advantage that the mounting bar 43 can be attached in a simple manner with the required number of self-tapping mounting screws 432, and subsequently, for example, only two mounting screws 423 are required for installation of the mounting rail 42. The mounting rail 42 can therefore be simpler in design and easier to install.

[0084] 7b further shows that the mounting rail 42 comprises several locking countersinks 4210 into which the latching tongues 411 of the mounting unit 41 can be inserted. The mounting unit 41 and / or the mounting rail 42 and / or the mounting bar 43 can be made from any material, such as plastic or metal.

[0085] Figure 8a shows the transmission device 6 of Figure 3 inserted into the door recess 110, which comprises a lever holder 62 holding a lever shaft 622 and a transmission lever 61, and which is removably connected to a mounting base 63 which is connected, e.g. screwed, to the door leaf 111.

[0086] Figure 8b shows the transmission device 6 of Figure 8a with the lever holder 62 detached from the mounting base 63 and the door leaf 111 shown in longitudinal cross section. The lever holder 62 comprises a locking plate 621 with a locking recess 620 and a bearing flange 623 (see Figure 6c) which holds a lever shaft 622.

[0087] The mounting base 63 is provided with a peripheral retaining flange 631, under which the locking plate 621 of the lever holder 62 can be pressed. In the process, the locking plate 621 is guided on the elastic latch element 632, which is displaced downward before it can engage with the locking recess of the lever holder 62. By inserting a tool, the latch element 632 can be displaced downward again, allowing the lever holder 62 to be removed from the mounting base 63.

[0088] Figure 8c shows the transmission lever 61 and lever holder 62 of Figure 8b detached from each other. The two lever parts 611, 612 of the transmission lever 61 have different dimensions but are oriented in the same direction, and therefore the transmission lever 61 only requires a small amount of space.

[0089] FIG. 9 shows the sliding door system 1 of FIG. 1 in a further preferred embodiment, with a preferably designed shock absorber 9 and a preferably designed mounting device 4. The mounting unit 41 of the mounting device 4, shown in cross section and detached from the mounting rail 42, is known from U.S. Pat. No. 9,341,011 (B2). In this embodiment, the mounting unit 41 is aligned parallel to the longitudinal axis of the running rail and includes an adjusting screw 416 rotatably mounted on a mounting body 415. By means of the adjusting screw 416, a slide holder 417, on which a slide 418 is mounted so as to be displaceable along a guideway, can be axially displaced. When the slide holder 417 is moved axially, the slide 418, which is connected to the connecting screw 416, is moved up or down along the guideway. By turning the adjusting screw 415, the sliding door 11 can thus be raised or lowered. For this adjustment, it is not necessary to remove the mounting unit 41 from the mounting rail 42, but access to the adjusting screw 416 must be ensured. To do this, the lever holder 62 of the transmission 6 is detached from the mounting base 63 as described above with reference to Figures 8a, 8b and 8c.

[0090] In this embodiment, the carriage 3 has only two rollers 32, one behind the other, the first of which is held by a single lock arm 982 of the locking part 98 as soon as the carriage body 31 hits the buffer body 91.

[0091] The shock absorber 9 also includes a shock absorber body 91 having an actuation channel 910. In this case, the actuation member 911 is not molded into the shock absorber body 91, but may be mounted to the actuation channel 910 by a mounting portion 9110. In this manner, the shock absorber 9 may be provided with a suitable actuation member 911. The mounting portion 9110 is preferably removable, so that the mounting portion 9110 can be detached and reinserted as needed. Figure 9 shows the mounting portion 9110 with the actuation member 911 after removal and after insertion into the shock absorber 9. [Explanation of symbols]
