Description

[0001] The invention relates to a sliding door system with a sliding door which comprises at least one activatable sealing device for closing a door opening.

[0002] US7891052B2 discloses a sliding door system with carriages guided along a track, which serve to hold a glass panel. The carriages are connected to the glass panel by fasteners in such a way that the upper edge of the glass panel can be accommodated in the cross-section of the track. This makes it possible to seal the space between the glass panel and the track almost tightly. However, in sliding doors with a thicker partition panel, for example, made of wood, accommodating the wooden panel in the cross-section of the track is hardly feasible.

[0003] US9290977B2 discloses a sliding door system with carriages connected to a door panel and movable along guide rails such that the door panel can be guided against the door frame in the area of ​​a door opening. Accordingly, this sliding door system requires appropriately designed guide rails.

[0004] US2011126471A1 discloses an activatable sealing device for a door or window sash, comprising a casing rail and a sealing strip held therein, which can be lowered by means of a lowering mechanism. The lowering mechanism comprises an actuating element that acts on leaf springs connected to the sealing strip via interconnected sliders. Pressure on the actuating element activates the sliders and deforms the leaf springs, thereby lowering the sealing strip. This process not only causes the sealing strip to slide downwards, but also shifts the support profile parts to the associated end face, which is why sealing can also be achieved at the end face. The actuating element protrudes from the sealing device and, when the door is closed, is pushed against the sealing device by the door frame.A second operating button can be provided on the opposite end of the door so that the lowering mechanism can be operated from both sides of the door.

[0005] US2019128054A1 discloses a sliding door with an activatable drop-down seal having an actuating element. The actuating element can be actuated by means of a transmission device screwed to the sliding door and an activation unit screwed to the door frame. The transmission device comprises a follower, which can interact with the activation unit, and a pivot arm connected to the follower, which can interact with the activation unit when the sliding door is moved to the end position. During this process, the follower is guided over a contact surface of the activation unit and rotated together with the pivot arm, which pushes the actuating element against the drop-down seal. This device ensures the correct positioning and installation of the activation unit.

[0006] EP3825503A1 discloses another sealing device for a displaceably mounted door leaf, comprising a seal with a sealing strip, a contact module, and an activation unit having a contact element for contacting the contact module when closing the door leaf, and a force transmission element. The sealing strip can be brought into a sealing position by means of an actuating mechanism. The movement of the contact element acts on an actuating element of the actuating mechanism via the force transmission element and activates the actuating mechanism.

[0007] It should be noted that sliding doors are typically equipped with mounting devices that connect to a dedicated drive. These mounting devices are often integrated into a door recess, which means that the sealing technology and the running technology are located next to each other, which can result in conflicts during installation, maintenance, and / or adjustment.

[0008] EP0818598B1 and US9341011B2 disclose mounting devices with mounting rails that are inserted into a recess on the top side of the door leaf of a sliding door. A mounting unit is axially displaceably and lockably mounted in each mounting rail. The mounting unit is connected by a connecting screw to the drive body of a drive that is guided in a guide rail.

[0009] In the device of EP0818598B1, the mounting unit for adjusting the height of the sliding door is released and extended out of the mounting rail until the connecting screw in front of the front side of the door leaf can be grasped and turned using a tool.

[0010] In the device of US9341011B2, the mounting unit comprises an adjusting screw aligned parallel to the longitudinal axis of the guide rail, by means of which a carriage holder, in which a carriage is mounted so as to be displaceable along guideways, can be axially displaced. During the axial displacement of the carriage holder, the carriage, which is connected to the connecting screw, is displaced up or down along the guideways. By turning the adjusting screw, the sliding door can therefore be raised or lowered. For this adjustment process, it is not necessary to remove the mounting unit from the mounting rail; however, access to the adjusting screw must be ensured.

[0011] EP0818598A1 further discloses a buffer device comprising a damping element and a locking part. The buffer device elastically stops the sliding door at an end stop and then holds it. The buffer device must be precisely positioned so that the sliding door is stopped in the closed position, i.e., exactly in front of the door opening to be closed.

[0012] Sliding door systems therefore often feature multiple devices that allow the sliding door's travel path and installation height to be adjusted. Additional drive devices may be provided that allow the sliding door to move automatically. The additional installation of an activatable sealing device places additional requirements on the adjustment of the sliding door system to ensure that the sealing devices are activated precisely at the locking position. The individual adjustment devices or device components of the running system and the sealing system must be coordinated with each other in this regard, which can involve considerable effort.

[0013] Furthermore, it must be ensured that there are no conflicts between the devices and device components used that would hinder the assembly, maintenance and / or adjustment of the individual device components of the sliding door system.

[0014] The present invention is therefore based on the object of creating an improved sliding door system with a sliding door having an activatable sealing device.

[0015] The sliding door system should be simple and compact and can be installed, maintained and adjusted with little effort.

[0016] The device parts of the sealing technology, such as the sealing device and elements for activating it, as well as the device parts of the running technology, such as the drives guided in a guide rail, e.g. between buffer devices, and mounting devices for connecting the drives to the sliding door, should work together advantageously and be optimally adapted to one another.

[0017] The components of the running technology and the components of the sealing technology should be used without conflict and / or interact. In particular, the elements of the running technology and the sealing technology should be able to be assembled, disassembled, and adjusted efficiently.

[0018] Furthermore, the interaction between the device parts of the running technology and the device parts of the sealing technology should be able to take place optimally without any mutual adjustments and adaptations.

[0019] The sliding door should be held as close as possible to the track so that the activatable sealing device must seal the smallest possible air gap.

[0020] The sealing device should also advantageously be operable. The activatable sealing device should have a sealing strip that can be extended upwards or downwards using any mechanism.

[0021] The parts of the sliding door device should be compact, inexpensive to manufacture and easy to install.

[0022] This object is achieved with a sliding door system according to claim 1. Advantageous embodiments of the invention are specified in further claims.

[0023] The sliding door system includes a sliding door; which sliding door is displaceable along a guide rail relative to a stationary activation part up to a closed position; which sliding door has a door leaf; which sliding door comprises at least two drives which have a drive body and running elements which are connected to the door leaf and which are displaceably mounted in the guide rail parallel to the longitudinal axis of the guide rail; which sliding door is equipped with an activatable sealing device which comprises an extendable sealing strip and an actuating element; and which sliding door is equipped with a transmission device which comprises a transmission element; wherein the activation part and the transmission device are arranged such that when the sliding door moves into the closed position, a force can be transmitted from the activation part via the transmission element to the actuating element in order to extend the sealing strip.

[0024] According to the invention, a stationary buffer device is provided which is intended to stop the sliding door in the closed position and which comprises the activation part.

[0025] Preferably, the buffer device is arranged within the cross-section of the guide rail. The guide rail is preferably arranged on the top side of the sliding door, so that the door leaf is suspended from the carriages, which can be moved within the guide rail. In the closed position, the sliding door can preferably tightly close a door opening.

[0026] The mutual coordination of the running technology and the sealing technology is thus achieved with reference to the buffer device, which must be correctly positioned. However, the mutual positioning of the buffer device and the activation part is eliminated, resulting in an overall reduction in the complexity of the sliding door system. Therefore, if the sliding door device is modified and requires readjustment, only the buffer device may need to be realigned.

[0027] The buffer device comprises a buffer body that holds or comprises at least one damping element or a damper and / or a locking part. Preferably, the buffer device comprises at least one central damping element or a central damper. Alternatively, the buffer device can be provided with a lateral damping element or a lateral damper on each side. In a further preferred embodiment, the lateral dampers and the central damper are provided in combination.

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

[0029] The locking part has at least one locking arm, by means of which the carriage can be held. The locking part is preferably fork-shaped and has two locking arms aligned towards the facing carriage. When the carriage enters, it is preferably coupled to the buffer device, with at least one locking arm elastically covering and holding one of the running wheels and / or a part of the carriage body. The carriages can be mounted mechanically or magnetically within the guide rail. The running elements can be, for example, rollers, wheels, sliding elements, or even ferromagnetic or permanent-magnetic magnetic elements.

[0030] The activation part, like the at least one damper or the locking part, can be detachably connected to the buffer body. In a preferred embodiment, the activation part is an integral component of the buffer body. The buffer body can advantageously be provided with the activation part. For example, the buffer body is manufactured in a single casting, thus eliminating the need for separate production of the buffer body and the activation part.

[0031] The buffer device is preferably clampable within the guide rail so that it can be moved to a suitable location and fixed or clamped.

[0032] The guide rail has a head piece and at least one side piece, on which a foot piece is provided. The guide rail preferably has a U-profile or a C-profile with two side pieces, which are connected to one another at one end by a head piece and connected to opposing foot pieces at the other end. The foot piece or foot pieces have running surfaces on their upper sides, on which the running elements of the carriages are supported.

[0033] Preferably, the buffer device or buffer body comprises foot elements that are supported on the foot pieces of the guide rail. In this embodiment, the buffer device is preferably provided with at least one threaded hole for a counterscrew, which is screwed against the head piece of the guide rail to press the buffer device or buffer body against the foot pieces of the guide rail and thus fix it.

[0034] An activation channel is preferably provided between the base elements of the buffer device, in which the activation part is provided and which is suitable for partially recessing the transmission element. The transmission element, optionally a transmission lever, can therefore enter the activation channel and interact there with the activation part. With this configuration of the buffer device, the sliding door can be raised further against the track, since the part of the transmission element exposed above the sliding door can enter the buffer device and preferably also into the cross-section of the track. By allowing the sliding door to be raised as far as possible against the track, the air gap between the upper edge of the sliding door and the lower edge of the track, which must be closed by the activatable sealing device, is reduced.Therefore, sealing devices that are easier to activate or otherwise optimized sealing devices can be used.

[0035] In a preferred embodiment, the activation part is designed as a ramp that runs straight or along a curve, preferably inclined to the longitudinal axis of the guide rail. However, the activation part can also have other geometric shapes that allow the transmission element to rotate.

[0036] In a preferred embodiment, the ramp runs along a curve whose steepness is selected such that the rotational speed of the transmission element, which is designed as a transmission lever, continuously reduces from a high value while the sliding door travels at a constant speed. This means that when traveling along the ramp, the transmission lever is first rotated quickly in order to quickly raise the sealing strip. Shortly before or after contact with the running rail, during which an elastic sealing element of the sealing strip is deformed, the rotational speed is reduced accordingly so that the sealing strip is pressed against the running rail in a controlled manner. The sections or gradients of the curve or the course of the ramp are preferably selected such that minimal stress on the device components used and optimal sealing results.

[0037] The transmission element of the transmission device is preferably a transmission lever comprising a first lever part, which is provided for interaction with the activation part, and a second lever part, which is provided for interaction with the actuating element of the sealing device. The two lever parts can be differently shaped, dimensioned, and aligned. Preferably, both lever parts are aligned parallel to each other or inclined to each other. The first lever part is typically longer than the second lever part and protrudes, for example, from a door recess in the door leaf.

[0038] The sliding door can have a door leaf made of glass or wood or another material.

[0039] Preferably, the door leaf is provided on the upper side with a receiving channel or a recess, which preferably runs from one end face to the other end face of the door leaf and is delimited on one or both sides by remaining parts of the door leaf.

[0040] Preferably, a door recess is provided, a) in which a mounting device is arranged, which has a mounting unit which is connected to one of the drives and is releasably held in a mounting rail which is connected to the door leaf; b) in which the activatable sealing device is arranged next to the mounting device; and c) in which the transmission device is arranged in front of the mounting device and the activatable sealing device.

[0041] The transmission device preferably comprises a lever holder that holds a lever shaft on which the transmission element, optionally the transmission lever, is rotatably mounted. This lever holder is preferably detachably held by a mounting base connected to the door leaf. The lever holder and the mounting base therefore preferably comprise corresponding holding elements and corresponding locking elements.

[0042] This design of the transmission device offers several advantages. To install the transmission device, the mounting base can first be connected to the door leaf, e.g., screwed. The lever bracket can then be inserted.

[0043] Before inserting the lever bracket, the mounting unit of the mounting device is pushed into the mounting rail, which has also been previously mounted within the door recess and screwed in place if necessary. Preferably, a mounting strip is fastened within the door recess, for example using self-tapping screws or wood screws. The mounting rail can then be secured using screws that are screwed into threaded holes in the mounting strip. This has the advantage that the mounting strip, which preferably has multiple mounting openings, can be mounted particularly easily and securely. The mounting rail can then be easily connected to the mounting strip, for example using just two mounting screws.

[0044] The mounting unit will be inserted into the mounting rail before the lever bracket is connected to the pre-assembled mounting base. The lever bracket can also be detachably connected to the mounting rail.

[0045] If the mounting unit needs to be removed from the mounting rail, for example, for maintenance or to adjust the sliding door, the lever holder of the transmission device is first loosened and removed with a simple movement or with the use of a tool. The mounting unit can then be pulled out of the mounting rail via the mounting base in front of the front 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 with a simple movement.

[0046] Since the mounting base is installed without a lever bracket and transmission lever, an area of ​​the mounting base that lies below the lever bracket after installation of the lever bracket can be used for inserting mounting screws. This eliminates the need for mounting flanges outside the area of ​​the lever bracket, allowing the lever bracket to be reduced to the dimensions of the mounting base. The transmission device therefore takes up the smallest possible space. This allows the transmission device to be securely mounted close to the front of the door leaf, preferably leaving space for a cover.

[0047] The invention is explained in more detail below with reference to the drawings. In the drawings: Fig. 1 shows a sliding door system 1 according to the invention with a sliding door 11 according to the invention, by means of which a door opening 10 enclosed by a door frame 12 can be tightly closed by means of sealing devices 8, 18 and which can be displaced by means of running gears 3 along a guide rail 2 up to a buffer device 9 which catches and holds the sliding door 11 in a closed position in which the door opening 10 is closed and which is provided with an activation part 911 (see Fig. 3 ), by means of which an activatable sealing device 8 can be actuated; Fig. 2a the end face of the sliding door 11 facing the buffer device 9 of Fig. 1 with a door recess 110 on the top side, in which the transmission device 6 provided for actuating the activatable sealing device 8 is arranged on the front side, and behind it, next to one another, the activatable sealing device 8 and a mounting device 4 are arranged, which is connected by a connecting part 35 to one of the drives 3 of Fig. 1 Fig. 2b the front side of the sliding door 11 of Fig. 2a with a view of the rear side of the mounted buffer device 9, which is clamped within the cross-section of the guide rail 2 by means of at least one counter screw 99; Fig. 3 the sliding door system 1 with the sliding door 11 of Fig. 1 in a spatial representation with the schematically shown door leaf 111, the running gear 3 guided in the guide rail 2 and facing the buffer device 9, the mounting device 4, the activatable sealing device 8 and the transmission device 6, which has a transmission lever 61 which is rotatably held by a lever shaft 622 and which can cooperate with a first lever part 611 with the buffer device 9 and with a second lever part 612 with an actuating element 82 of the activatable sealing device 8; Fig. 4 the sliding door 11 of Fig. 3 with a view of the facing end face of the door leaf 111; Fig. 5a the activatable sealing device 8 of Fig. 4 with a schematically shown extension mechanism 84 before activation by the symbolically shown transmission lever 61 of the transmission device 6; Fig. 5b the activatable sealing device 8 of Fig. 5a after activation by the symbolically shown transmission lever 61 of the transmission device 6 and the actuation of the extension mechanism 84, by means of which the sealing strip 81 was raised; Fig. 6a the buffer device 6 of Fig. 1 from the side; Fig. 6b the buffer device 6 of Fig. 6a from the front; Fig. 6c the buffer device 6 of Fig. 6a in exploded view; Fig. 7a the mounting device 4 of Fig. 3 with a mounting rail 42, in which a mounting unit 41 connected to a drive 3 is held and which in this preferred embodiment is connected to a mounting bar 43; Fig. 7b the mounting device 4 of Fig. 7a in exploded view with a longitudinal section through the mounting unit 41, which is connected by a connecting screw 35 to the drive body 31 of the associated drive 3; Fig. 8a the transmission device 6 inserted into the door recess 110 of Fig. 3 , which has a lever holder 62 which holds the lever shaft 622 and the transmission lever 61 and which is detachably connected to a mounting base 63 which is connected to the door leaf 111; Fig. 8b the transmission device 6 of Fig. 8a with the lever holder 62 detached from the mounting base 63 and the door leaf 111 shown in a longitudinal section; Fig. 8c the transmission lever 61 and the lever holder 62 of Fig. 8b detached from each other; and Fig. 9 the sliding door system 1 of Fig. 1 in a further preferred embodiment with a preferably designed buffer device 9 and a preferably designed mounting device 4.

[0048] Fig. 1 shows a sliding door system 1 according to the invention with a sliding door 11 according to the invention, by means of which a simple door opening 10 or a door opening 10 enclosed by a door frame 12 can be closed. The sliding door 11 comprises a door leaf 111, the front quarter of which has been cut away in order to partially expose activatable sealing devices 8 arranged on the top side and preferably also on the bottom side in a door recess 110. Also shown on the top side of the sliding door 11 is a first mounting device 4, which is connected on the one hand to the door leaf 111 and on the other hand to a first drive 3. A second mounting device 4, which is connected on the one hand to the door leaf 111 and on the other hand to a second drive 3, is covered by the rear side of the door leaf 111.

[0049] The two carriages 3 are guided in a guide rail 2 and can be moved along this rail until the first carriage 3 encounters a buffer device 9 according to the invention, which is mounted in the guide rail 2. The left part of the guide rail 2 is cut along the longitudinal axis to show the buffer device 9.

[0050] By means of the buffer device 9, the sliding door 11 is elastically held in an end position or closed position in front of the door opening 10 and preferably by a locking part 98 (see Fig. 3 ) so that it is held in a defined position, namely the locking position, and cannot retract automatically. Only by applying force can the sliding door 11 be released from the locking part 98 and retracted again.

[0051] Using an activation part 911 (see Fig. 3 ), which is connected to the buffer device 9, the activatable sealing device 8 is also actuated, by means of which an air gap between the upper edge of the sliding door 11 and, for example, the lower edge of the guide rail 2 can be sealed.

[0052] The activatable sealing device 8, which is preferably provided on the underside of the sliding door 11, can also be actuated when the closed position is reached, as is known from the prior art described at the beginning.

[0053] Conventional seals 18 are preferably provided on the vertical frame strips 121, 122 of the door frame 12, which seal the air gap between the sliding door 11 and the vertical frame strips 121, 122 as soon as the sliding door 11 reaches the closed position.

[0054] In the closed position of the sliding door 11, the door opening 10 is therefore completely closed and sealed in this preferred embodiment.

[0055] Fig. 2a shows the front side of the sliding door 11 facing the buffer device 9 of Fig. 1 with the door recess 110 on the upper side of the door leaf 111, in which the transmission device 6 provided for actuating the activatable sealing device 8 is arranged on the front side, and behind it, next to one another, the activatable sealing device 8 and the first mounting device 4 are arranged, which are connected by a connecting part 35, for example a connecting screw, to the first drive 3 of Fig. 1 The buffer device 9 has been removed from the guide rail 2 to reveal the first carriage 3.

[0056] The guide rail 2 has two side pieces 22 which are connected to each other at the top by a head piece 21 and which are connected to each other at the bottom by foot pieces 23 which face each other.

[0057] The carriages 3 comprise a carriage body 31, which holds running elements 32 on both sides, which are supported on the foot pieces 23 of the guide rail 2. Facing the buffer device 9, the carriage body 31 further comprises a stop part 311, which abuts the damping element or elements of the buffer device 9 when the sliding door 11 reaches the closed position.

[0058] Directly adjacent to the front side of the door leaf 111 is the transmission device 6, which comprises a transmission element in the form of a transmission lever 61, a lever holder 62, and a mounting base 63. The lever holder 62 comprises a holding plate 621, which is releasably anchored in the mounting base 63, and a lever shaft 622, by means of which the transmission lever 61 is rotatably mounted. The transmission lever 61 comprises a first lever part 611, which can interact with the buffer device 9, and a second lever part 612, which can interact with the actuating element 82 of the activatable sealing device 8. Both lever parts 611, 612 are located next to one another and are dimensioned such that an interaction with the actuating element 82 and the buffer device 9 occurs as soon as the sliding door 11 moves into the closed position.

[0059] The mounting base 63 comprises holding elements and a locking element 631, by means of which the lever holder 62 is releasably held. The lever holder 62 comprises a locking recess 620 into which the locking element 631 can engage. The locking recess 620 simultaneously forms a window through which a tool, e.g., a screwdriver, can be inserted to press the locking element 631 downward and release it from the lever holder 62. The lever holder 62 can therefore be detached from the mounting base 63 with one hand, if necessary.

[0060] The activatable sealing device 8 comprises a housing 83 in which the extendable sealing strip 81 and an extension mechanism 84 (see Fig. 5a ), which can be actuated by means of the actuating element 82.

[0061] In addition to the activatable sealing device 8, a mounting device 4 is arranged within the door recess 110 for each of the drives 3. The mounting device 4 shown comprises a retaining rail 42 in which a mounting unit 41 is displaceable and can be locked in one or more positions by means of a locking element, such as a locking tongue 411.

[0062] Fig. 2b shows the front side of the sliding door 11 of Fig. 2a View of the rear of the assembled buffer device 9, which is clamped within the cross-section of the running rail 2 by means of at least one counterscrew 99. The buffer device 9 comprises a buffer body 91 with foot elements 912, which are supported on the foot pieces 23 of the running rail 2. A counterscrew 99 is held in a threaded bore within the buffer body 91. By turning this counterscrew 99 against the head piece 21 of the running rail 2, the buffer body 91 is pressed and clamped against the foot pieces 23 of the running rail. The buffer device 9 can therefore be inserted into the running rail 2, moved to a suitable position, and fixed by tightening the counterscrews 99.

[0063] Furthermore, the buffer body 91 has an activation part 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 moves against the buffer device 9. During this process, the transmission lever 61 is rotated, the second lever part 612 is guided against the actuating element 82, the extension mechanism of the sealing device 8 is actuated, and the sealing strip 81 is guided against the underside of the running rail 2, thereby tightly sealing the air gap between the upper edge of the door leaf 111 and the lower edge of the running rail 2. At least the uppermost part of the device strip 81 is preferably elastic and is thus pressed flat against the underside of the running rail 2. The movement of the sealing strip 81 during the closing process is symbolized by an arrow.

[0064] It can be seen that the activation part 911 is practically completely integrated into the buffer device 9, which is why it does not require any additional space. The buffer device 9 according to the invention can therefore be manufactured with the dimensions of conventional buffer devices 9.

[0065] Fig. 3 shows the sliding door system 1 with the sliding door 11 of Fig. 1 in a spatial representation with the schematically shown door leaf 111, the first drive 3 guided in the guide rail 2 and facing the buffer device 9, the first mounting device 4, the activatable sealing device 8 and the transmission device 6. The guide rail 2 was cut along the longitudinal axis.

[0066] In a preferred embodiment, the buffer device 9 is shown in a longitudinal section along the central axis. The section runs through two threaded holes or screw channels 990 in which the counter screws 99 are rotatably held. The screw channels 990 are open at the bottom so that a tool can be coupled to the counter screws 99 from below in order to rotate them against the head piece 21 of the guide rail 2 shown in the sectional view.

[0067] On the underside, the buffer body 91 has the activation part 911, which is designed as a ramp. The buffer body 91 therefore comprises the activation part 911 in one piece, which is fully integrated into the buffer body 91 and thus does not take up any additional space. For this purpose, the buffer body 91 has a preferably provided activation channel 910 between the foot elements 912, into which the first lever part 611 of the transmission lever 61 can enter. Upon further displacement of the sliding door 11 against the buffer device 9, the transmission lever 61 is rotated clockwise, whereby the second lever part 612 is guided against the actuating element 82 of the activatable sealing device 8. The activation channel 910 thus allows the transmission lever 61 to be at least partially accommodated in the activation channel 910, which is why the sliding door 11 can be raised almost to the running rail 2, resulting in only a minimal air gap between them.

[0068] At the front, the buffer device 9 has two lateral dampers 95, only one of which is shown, and a central damper 96. The central damper 96 is made, for example, of an elastic material such as rubber or plastic. The lateral dampers 95 preferably have a piston and a cylinder that are displaceable relative to one another.

[0069] Furthermore, the buffer device 9 has a preferably elastic locking part 98 on its upper side, which is anchored at the rear in the buffer body 91 and is elastically rotatable against the buffer body 91 by a symbolically shown screw 981. The locking part 98, cut in the longitudinal direction, also comprises two elastic locking arms 982 (only one shown), which are directed toward the facing first carriage 3. The two elastic locking arms are each provided to elastically engage over and hold one of the rollers 32 of the carriage 3.

[0070] Fig. 3 further shows the activatable sealing device 8, which is described below with reference to Fig. 5a und Fig. 5b will be explained in more detail, the mounting device 4, which will be described below with reference to Fig. 4 , Fig. 7a und Fig. 7b will be explained in more detail, as well as the transmission device 6, which will be described below with reference to Fig. 8a, Fig. 8b und Fig. 8c is explained in more detail.

[0071] Fig. 4 shows the sliding door 11 of Fig. 3 with a view of the facing end face of the door leaf 111. The mounting device 4 is arranged behind the transmission device 6 in the door recess 110. The mounting rail 42, which is firmly connected to the door leaf 111, for example, by screwing, has a receiving channel 420 delimited by side elements with opposing retaining flanges 421. The mounting unit 41 is inserted into the receiving channel 420 and is held by the retaining flanges 421. The connecting screw 35, which is screwed into the drive body 31 of the drive 3, protrudes between the retaining flanges 421.

[0072] The retaining flanges 421 also have locking recesses 4210 into which a locking tongue 411 of the mounting unit 41 is engaged. By lifting the locking tongue 411, the mounting unit 41 can be released and moved within the mounting rail 42 to another locking position.

[0073] With reference to Fig. 2a It has already been described that the lever holder 62 can be released and removed with virtually one hand. If the drive 3 requires maintenance or adjustment, the locking connections of the mounting unit 41 and the lever holder 62 are released, after which the mounting unit 41 can be extended with the drive 3. After maintenance or adjustment of the drive 3, the mounting unit 41 is pushed back into the mounting rail 42 and locked into place. The lever holder 62 is then reconnected to the mounting base 63 with one hand.

[0074] Fig. 5a shows the activatable sealing device 8 of Fig. 4 with a schematically shown extension mechanism 84 prior to activation by the symbolically shown transmission lever 61 of the transmission device 6. In this preferred embodiment, the extension mechanism 84 comprises a plurality of leaf springs 141, which are connected to the actuating element 82 by means of push rods 842. By displacing the actuating element 82, the leaf springs 141 are bent such that the sealing strip 81, which preferably has an elastic closing element 811, is raised and elastically pressed against the underside of the guide rail 2.

[0075] Fig. 5b shows the activatable sealing device 8 of Fig. 5a after activation by the symbolically shown transmission lever 61, which was guided against the actuating element 82, and the actuation of the extension mechanism 84, by means of which the sealing strip 81 was raised.

[0076] Fig. 6a shows the buffer device 6 of Fig. 1 from the side with the locking part 98, which is anchored at the rear by an anchor part 981 in the buffer body 91 and which has two elastic anchor arms 982 on the front, each bent to engage and hold a running wheel 32. Since the activation part 911 is integrated and recessed into the buffer body 91, only its lower part is visible.

[0077] Fig. 6b shows the buffer device 6 of Fig. 6a from the front. It can be seen that the two lateral dampers 95 are arranged symmetrically to the central damper 96. The two locking arms 982 and one of the counterscrews 99 are visible on the top. On the underside of the buffer device 9, the foot elements 912 of the buffer body 91 are shown, between which the activation channel 910 is recessed into the buffer body 91. The channel bottom of the activation channel 910 forms the preferably ramp-shaped activation part 911. Holes are inserted into the ramp 911 into which a screwdriver can be inserted to turn the counterscrew 99 and the fastening screw 981, by which the locking part 98 is held and preloaded.

[0078] Fig. 6c shows the buffer device 6 of Fig. 6a in exploded view. It is shown that the buffer body 91 has two lateral openings 915 for receiving the lateral dampers 95, a central opening 916 for receiving the central damper 96, and a retaining lug 918 for holding the anchor part 981 of the locking part 98. Symbolically, it is shown that the lateral dampers 95 preferably have a piston 951, which is connected to a piston rod 953 and is displaceably mounted in a damping cylinder 952. In the damping cylinder 952, for example, a viscous substance or a medium, such as air, is provided, which is displaced by the piston 951. The piston 951 is preferably returned to its starting position by an elastic element.

[0079] Buffer body 91 is preferably made of plastic or metal.

[0080] Fig. 7a shows the mounting device 4 of Fig. 3 and Fig. 4 with the mounting rail 42, in which the mounting unit 41 connected to the drive 3 is held and which, in this preferred embodiment, is supported on a mounting strip 43. In a preferred embodiment, the mounting strip 43 can be connected to the door leaf 111 of the sliding door 11 within the door recess 110 and is preferably made of metal. To simplify the coupling of the mounting rail 42 to the mounting strip 43, corresponding coupling elements 429, 439 are provided. The coupling elements 429, 439 ensure that corresponding mounting holes and threaded holes of the mounting rail 42 and the mounting strip 43 are always coaxially aligned.

[0081] Fig. 7b shows the mounting device 4 of Fig. 7a in exploded view and with a longitudinal section through the assembly unit 41. The locking tongue 411, which is Fig. 7a is recessed into a locking recess 4210, is exposed at the end and is preferably elastic. The connecting screw 35, which is connected to the drive body 31 of the drive 3, is rotatably held in a connecting channel 410 of the mounting unit 41.

[0082] The mounting strip 43, which is in Fig. 7b is separated from the mounting rail 42, has mounting openings 430 and threaded holes 431. Self-tapping screws 432, by means of which the mounting strip 43 is connected to the door leaf 111, can be passed through the mounting openings 430. The mounting rail 42 can then be connected to the mounting strip 43 by inserting mounting screws 423 through mounting openings 4230 in the mounting rail 42 into the threaded holes 431 of the mounting strip 43. This has the advantage that the mounting strip 43 can be easily mounted with the required number of self-tapping screws 432 and, for example, only two mounting screws 423 are subsequently required to install the mounting rail 42. The mounting rail 42 can therefore be designed more simply and can be mounted more easily.

[0083] Fig. 7b further shows that the mounting rail 42 has a plurality of locking recesses 4210 into which the locking tongue 411 of the mounting unit 41 can be recessed. The mounting unit 41 and / or the mounting rail 42 and / or the mounting strip 43 can be made of any material, such as plastic or metal.

[0084] Fig. 8a shows the transmission device 6 inserted into the door recess 110 of Fig. 3 which has a lever holder 62 which holds the lever shaft 622 and the transmission lever 61 and which is detachably connected to a mounting base 63 which is connected, for example screwed, to the door leaf 111.

[0085] Fig. 8b shows the transmission device 6 of Fig. 8a with the lever holder 62 detached from the mounting base 63 and the door leaf 111 shown in a longitudinal section. The lever holder 62 comprises a holding plate 621 with a locking recess 620 and bearing flanges 623 (see Fig. 6c ), which hold the lever shaft 622.

[0086] The mounting base 63 has a circumferential retaining flange 631, under which the retaining plate 621 of the lever holder 62 can be pushed. During this process, the retaining plate 621 is guided over an elastic locking element 632, which is displaced downward before it can engage the locking recess of the lever holder 62. By inserting a tool, the locking element 632 can be displaced downward again to release the lever holder 62 from the mounting base 63.

[0087] Fig. 8c shows the transmission lever 61 and the lever holder 62 of Fig. 8b detached from each other. The two lever parts 611, 612 of the transmission lever 61 are differently dimensioned but aligned in the same direction, which is why the transmission lever 61 takes up very little space.

[0088] Fig. 9 shows the sliding door system 1 of Fig. 1 in a further preferred embodiment with a preferably configured buffer device 9 and a preferably configured mounting device 4. The mounting unit 41 of the mounting device 4, which was removed from the mounting rail 42 and is shown in a sectional view, is known from US9341011B2. In this embodiment, the mounting unit 41 comprises an adjusting screw 416 aligned parallel to the longitudinal axis of the guide rail and rotatably mounted in a mounting body 415, by means of which a slide holder 417, in which a slide 418 is mounted displaceably along guide tracks, can be axially displaced. During the axial displacement of the slide holder 417, the slide 418, which is connected to the connecting screw 416, is displaced up or down along the guide tracks. By turning the adjusting screw 415, the sliding door 11 can therefore be raised or lowered.For this adjustment process, it is not necessary to remove the mounting unit 41 from the mounting rail 42. However, access to the adjusting screw 416 must be ensured. For this purpose, the lever holder 62 of the transmission device 6 is detached from the mounting base 63, as described above with reference to . Fig. 8a, Fig. 8b und Fig. 8c was described.

[0089] In this embodiment, the carriage 3 has only two rollers 32 arranged one behind the other, of which the first roller 32 is held by the single locking arm 982 of the locking part 98 as soon as the carriage body 31 hits the buffer device 9.

[0090] The buffer device 9 also has a buffer body 91 with an activation channel 910. In this case, the activation part 911 is not molded onto the buffer body 91, but can be anchored in the activation channel 910 by a mounting part 9110. In this way, the buffer device 9 can be equipped with a suitable activation part 911. The mounting part 9110 is preferably detachably held so that it can be removed and reinserted as needed. Fig. 9 the mounting part 9110 with the activation part 911 is shown after removal and after insertion into the buffer device 9. List of reference symbols:
