Description

The invention relates to a sliding door system with a sliding door that includes at least one activatable sealing device to close off a door opening, and a buffer device for the sliding door system.

The US7891052B2 discloses a sliding door system with drives guided along a running rail, which are used to hold a glass panel. The drives are connected to the glass plate by fastening means in such a way that the upper edge of the glass plate can be accommodated in the cross section of the running rail. This makes it possible to close off the space between the glass plate and the running rail almost tightly. On the other hand, in the case of sliding doors with a thicker dividing plate made of wood, for example, it is hardly possible to accommodate the wooden plate in the cross section of the running rail.

The US9290977B2 discloses a sliding door system with drives that are connected to a door panel and can be slid along running rails in such a way that the door panel can be guided against the door frame in the area of a door opening. Correspondingly designed running rails are therefore required for this sliding door system.

The US2011126471A1 discloses an activatable sealing device for a door or window sash with a housing rail and a sealing strip held therein, which can be lowered by means of a lowering mechanism. The lowering mechanism comprises an actuating element which acts on leaf springs which are connected to the sealing strip via slides which are connected to one another. Pressure on the actuating element actuates the slides and deforms the leaf springs, causing the sealing strip to be lowered. During this process, not only is the sealing strip shifted downwards, but also a shift of carrier profile parts depending on the assigned end face, which is why sealing can also take place at the end face. The actuating element protrudes from the sealing device and is pushed against the sealing device by the door frame when the door is closed. On the A second actuating button can be provided on the opposite end face of the door, so that the lowering mechanism can be actuated from both sides of the door.

The 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 which is screwed to the sliding door and an activation unit which is screwed to the door frame. The transmission device comprises a follower, which can interact with the activation unit, and a swivel arm connected to the follower, which can interact with the activation unit when the sliding door is moved into the end position. During this process, the idler is guided over a contact surface of the activation unit and rotated together with the swivel arm, which pushes the actuating element against the drop-down seal. This device allows the correct positioning and assembly of the activation unit.

It should be noted that the sliding doors are usually provided with mounting devices that connect to an associated drive. The assembly devices are often integrated into a door recess, which is why the sealing technology and the running technology are arranged next to one another, which can result in conflicts during assembly, maintenance and/or adjustment.

The EP0818598B1 and the US9341011B2 disclose mounting devices with mounting rails that are inserted into a recess at the top of the door panel of a sliding door. A mounting unit is mounted in each mounting rail in an axially displaceable and lockable manner. The mounting unit is connected to the carriage body of a carriage, which is guided in a running rail, by a connecting screw.

In the device of EP0818598B1 the mounting unit for height adjustment 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 detected and rotated by means of a tool.

In the device of US9341011B2 the assembly unit includes an adjusting screw aligned parallel to the longitudinal axis of the running rail, by means of which a carriage holder, in which a carriage is mounted so as to be displaceable along guide tracks, can be displaced axially. 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. The sliding door can therefore be raised or lowered by turning the adjusting screw. It is not necessary to remove the mounting unit from the mounting rail for this adjustment process. however, access to the adjustment screw must be guaranteed.

The EP0818598A1 further discloses a buffering device having a cushioning member and a locking member. The sliding door is elastically stopped at an end stop and then held by the buffer device. The buffer device must be positioned precisely so that the sliding door is stopped in the closed position, ie exactly in front of the door opening to be closed.

Sliding door systems therefore often have a number of devices that make it possible to adjust the path and the installation height of the sliding door. Possibly additional drive devices are provided, by means of which the sliding door can be moved automatically. With the additional installation of an activatable sealing device, additional requirements for the adjustment of the sliding door system must be met in order to ensure that the sealing devices are activated exactly at the closing position. The individual adjusting devices or device parts of the running technology and the sealing technology must be coordinated with one another in this respect, which can cause considerable effort.

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

The present invention is therefore based on the object of creating an improved sliding door system with a sliding door that has a sealing device that can be activated, such a sliding door and an improved buffer device for the sliding door system.

The sliding door system should have a simple and compact design and be able to be installed, maintained and adjusted with little effort.

The device parts of the sealing technology, such as the sealing device and elements for activating the same, as well as the device parts of the running technology, such as the carriages guided in a running rail, e.g. between buffer devices, and assembly devices for connecting the carriages to the sliding door, should work together advantageously and be optimally adapted to one another.

The device parts of the running technology and the device parts of the sealing technology should be used and/or interact without conflict. In particular, it should be possible to advantageously assemble, disassemble and adjust the elements of the running technology and the sealing technology.

Furthermore, the interaction of the device parts of the running technology and the device parts of the sealing technology should be able to take place optimally practically without mutual adjustments and adjustments.

The sliding door should be kept as close as possible to the running rail, so that the sealing device that can be activated has to seal off an air gap that is as small as possible.

The sealing device should also be able to be actuated advantageously. The activatable sealing device should have a sealing strip that can be extended upwards or downwards with any mechanism.

The parts of the sliding door device should be compact, inexpensive to manufacture and easy to assemble.

This object is achieved with a sliding door system according to claim 1, a sliding door according to claim 11 and a buffer device according to claim 12. Advantageous configurations of the invention are specified in further claims.

The sliding door system includes a sliding door;

• which sliding door is displaceable along a running rail relative to a stationarily arranged activation part up to a closed position;
• which sliding door has a door panel;
• which sliding door comprises at least two carriages, which have a carriage body and running elements which are connected to the door leaf and which are slidably mounted in the running rail parallel to the longitudinal axis of the running rail;
• which sliding door is equipped with an activatable sealing device comprising an extendable sealing strip and an actuating element; and
• which sliding door is equipped with a transmission device comprising a transmission element;
• wherein the activation part and the transmission device are arranged such that when the sliding door enters 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.

According to the invention, a stationary arranged buffer device is provided, which is provided for stopping the sliding door in the closed position and which comprises the activation part.

The buffer device is preferably arranged within the cross section of the running rail. The running rail is preferably at the Arranged at the top of the sliding door so that the door leaf is hung on the drives that can be slid within the track. With the sliding door in the closed position, a door opening can preferably be tightly closed.

The mutual adjustment of the running technique and the sealing technique is thus made with reference to the buffer device that is to be positioned correctly. On the other hand, there is no mutual positioning of the buffer device and the activation part, so that the overall complexity of the sliding door system is reduced. If there is a change in the sliding door device, which requires a new adjustment, only the buffer device may need to be realigned.

The buffer device comprises a buffer body which holds or comprises at least one damping element or damper and/or locking part. The buffer device preferably comprises at least one central damping element or one central damper. Alternatively, the buffer device can be provided on both sides with a lateral damping element or a lateral damper. In a further preferred embodiment, the lateral dampers and the central damper are provided in combination.

The damping elements, lateral dampers and/or central dampers, can be made from 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.

The locking part has at least one locking arm, by means of which the drive can be held. The locking part is preferably designed in the shape of a fork and is aligned with two locking arms in the direction of the facing drive. 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 part of the carriage body. The drives can be stored mechanically or magnetically within the running rail. The running elements can be, for example, rollers, wheels, sliding elements or else ferromagnetic or permanent magnet elements.

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 part of the buffer body. The buffer body can advantageously be provided with the activation part. For example, the buffer body is made in one piece, which means that the buffer body and activation part do not have to be manufactured separately.

The buffer device can preferably be braced within the running rail so that it can be moved to a suitable location and fixed or braced.

The running rail has a head piece and at least one side piece on which a foot piece is provided. The running 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 which are connected at the other end to foot pieces directed towards one another. The foot piece or the foot pieces have running surfaces on the upper side, on which the running elements of the carriages are supported.

The buffer device or the buffer body preferably has foot elements which are supported on the foot pieces of the running rail. In this embodiment, the buffer device is preferably provided with at least one threaded hole for a lock screw which is screwed against the head piece of the running rail in order to press the buffer device or the buffer body against the foot pieces of the running rail and thus to fix it.

An activation channel is preferably provided between the foot elements of the buffer device, in which the activation part is provided and which is suitable for partial recessing of 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 running rail, since the part of the transmission element exposed above the sliding door can enter the buffer device and preferably also the cross-section of the running rail. Since the sliding door can be raised against the running rail as much as possible, the air gap between the upper edge of the sliding door and the lower edge of the running rail, which is to be closed by the sealing device that can be activated, is reduced. Sealing devices that can be activated more easily or otherwise optimized sealing devices can therefore be used.

In a preferred embodiment, the activation part is designed as a ramp, which runs straight or along a curve, preferably inclined to the longitudinal axis of the running rail. The activation part, on the other hand, can also have other geometric shapes that allow the transmission element to be rotated.

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 at a constant speed of the sliding door. That is, when driving along the ramp, the transmission lever is first turned quickly in order to quickly raise the weatherstrip. Shortly before or after contact is made with the running rail, during which an elastic sealing element of the sealing strip is deformed, the rotational speed is correspondingly reduced 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 in such a way that a minimum load on the device parts used and an optimal seal result.

The transmission element of the transmission device is preferably a transmission lever, which has a first lever part, which is provided for cooperation with the activation part, and a second lever part intended for cooperation with the actuating element of the sealing device. The two lever parts can be shaped, dimensioned and aligned differently. Both lever parts are preferably aligned parallel to one another or at an angle to one another. The first lever part is typically longer than the second lever part and protrudes, for example, from a door recess in the door leaf.

The sliding door can have a door leaf made of glass or also made of wood or another material.

The door leaf is preferably provided with a receiving channel or a recess on the upper side, 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.

1. a) in der eine Montagevorrichtung angeordnet ist, die eine Montageeinheit aufweist, die mit einem der Laufwerke verbunden und in einer Montageschiene, die mit dem Türblatt verbunden ist, lösbar gehalten ist;
2. b) in der neben der Montagevorrichtung die aktivierbare Dichtungsvorrichtung; und
3. c) in der vor der Montagevorrichtung und der aktivierbaren Dichtungsvorrichtung die Übertragungsvorrichtung angeordnet ist.

A door opening is preferably provided

1. a) in which a mounting device is arranged, which has a mounting unit which is connected to one of the drives and is detachably held in a mounting rail which is connected to the door leaf;
2. b) in the next to the assembly device, the activatable sealing device; and
3. c) in which the transmission device is arranged in front of the assembly device and the activatable sealing device.

The transmission device preferably comprises a lever holder which holds a lever shaft on which the transmission element, optionally the transmission lever, is rotatably mounted, and which lever holder is preferably detachably held by a mounting base which is connected to the door leaf. The lever holder and the mounting base therefore preferably comprise holding elements which correspond to one another and latching elements which correspond to one another.

This configuration of the transmission device has several advantages. To mount the transmission device, the mounting base can first be connected to the door leaf, e.g. screwed. As a result, the lever bracket can be used.

Before inserting the lever mount, the mounting unit of the mounting device is pushed into the mounting rail, which was also previously mounted inside the door recess, screwed if necessary. A mounting strip is preferably fastened within the door recess, for example by means of self-tapping screws or wood screws. The mounting rail can then be attached using screws that are screwed into threaded holes in the mounting rail. This has the advantage that the mounting strip, which preferably has a number of mounting openings, can be mounted in a particularly simple and stable manner. As a result, the mounting rail can be connected to the mounting strip in a simple manner, for example with only two mounting screws.

The mounting unit will slide 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 bar.

If the mounting unit has to be removed from the mounting rail again, for example for the purposes of maintenance or adjustment of the sliding door, the lever holder of the transmission device is first released and removed with a manipulation or the intervention of a tool. The mounting unit can now be pulled out of the mounting rail in front of the face of the door leaf via the mounting base. 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 flick of the wrist.

Since the mounting base is assembled without lever bracket and transmission lever, a portion of the mounting base that is below the lever bracket after the lever bracket is mounted can be used for inserting mounting screws. There are thus no mounting flanges required outside the area of the lever mount, allowing the lever mount 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 stably mounted close to the face of the door leaf, preferably leaving space free for accommodating a cover.

the sliding door system 1 from 1 in a further preferred embodiment with a preferably configured buffer device 9 and a preferably configured mounting device 4.

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 in a door recess 110 on the upper side and preferably also on the lower side. A first assembly device 4 is also shown on the upper side of the sliding door 11, which is connected to the door leaf 111 on the one hand and to a first running gear 3 on the other hand. 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.

The two carriages 3 are guided in a rail 2 and can be slid along it until the first carriage 3 meets a buffer device 9 according to the invention, which is mounted in the rail 2 . The left part of the track 2 is sectioned along the longitudinal axis to show the buffer device 9 .

The sliding door 11 is elastically stopped in an end position or closed position in front of the door opening 10 by means of the buffer device 9 and preferably by a locking part 98 (see 3 ) fixed so that it is held in a defined position, namely the locking position, and cannot move back on its own. The sliding door 11 can only be detached from the locking part 98 and moved back again by exerting force.

By means of an activation part 911 (see 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 running rail 2 can be sealed.

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 outset.

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.

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

Figure 2a shows the front side of the sliding door 11 facing the buffer device 9 from 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, side by side, the activatable sealing device 8 and the first assembly device 4 are arranged, which are connected by a connecting part 35, for example a connecting screw , with the first drive 3 of 1 connected is. The buffer device 9 has been removed from the running rail 2 in order to reveal the view of the first carriage 3.

The running rail 2 has two side pieces 22 which are connected to one another at the top by a head piece 21 and which are connected to one another at the bottom by foot pieces 23 which face one another.

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

The transmission device 6 is mounted directly adjacent to the end face of the door leaf 111 and has a transmission element in the form of a transmission lever 61 , a lever mount 62 and a mounting base 63 . The lever holder 62 comprises a holding plate 621, which is detachably anchored in 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, 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 next to each other and are dimensioned in such a way 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.

The mounting base 63 includes holding elements and a latching element 631, by means of which the lever holder 62 is detachably held. The lever mount 62 includes a latching recess 620 into which the latching element 631 can engage. At the same time, the locking recess 620 forms a window through which a tool, e.g. The lever bracket 62 can therefore be detached from the mounting base 63 with a flick of the wrist if necessary.

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

In addition to the sealing device 8 that can be activated, a mounting device 4 is arranged within the door recess 110 for each of the carriages 3 . The assembly device 4 shown comprises a retaining rail 42 in which an assembly unit 41 can be displaced and locked in one or more positions by means of a latching element, such as a latching tongue 411 .

Figure 2b shows the end face of the sliding door 11 of Figure 2a with a view of the rear of the mounted buffer device 9, which is braced within the cross section of the running rail 2 by means of at least one lock screw 99. The buffer device 9 includes a buffer body 91 with foot elements 912 which are supported on the foot pieces 23 of the running rail 2 . Within the buffer body 91 a lock screw 99 is held in a threaded hole. By turning this lock screw 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 lock screws 99.

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 drive 3 against the Buffer device 9 moves. 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 closing the air gap between the upper edge of the door leaf 111 and the lower edge of the Running rail 2 is sealed. At least the uppermost part of the device strip 81 is preferably designed to be elastic and is thereby 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.

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

3 shows the sliding door system 1 with the sliding door 11 from 1 in a spatial representation with the schematically shown door leaf 111, the first carriage 3 guided in the running rail 2 and facing the buffer device 9, the first assembly device 4, the activatable sealing device 8 and the transmission device 6. The running rail 2 was cut along the longitudinal axis.

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 lock screws 99 are rotatably held. The screw channels 990 are open at the bottom so that a tool can be coupled to the lock screws 99 from below in order to turn them against the head piece 21 of the running rail 2 shown in a sectional view.

On the underside, the buffer body 91 has the activation part 911, which is designed as a ramp. The buffer body 91 therefore integrally includes the activation part 911, which is fully integrated into the buffer body 91 and thus no additional space in claims. For this purpose, the buffer body 91 has an activation channel 910 that is preferably provided between the foot elements 912 and into which the first lever part 611 of the transmission lever 61 can enter. If the sliding door 11 is displaced further against the buffer device 9 , the transmission lever 61 is rotated clockwise, as a result of which the second lever part 612 is guided against the actuating element 82 of the sealing device 8 which can be activated. 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 up to the running rail 2 and only a minimal air gap results between them.

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 consists, for example, of an elastic material such as rubber or plastic. The lateral dampers 95 preferably have a piston and a cylinder which can be displaced in relation to one another.

Furthermore, the buffer device 9 has a preferably elastic locking part 98 on the upper side, which is anchored on the rear side in the buffer body 91 and can be rotated elastically against the buffer body 91 by means of a screw 981 shown symbolically. The longitudinally cut locking part 98 also includes two elastic locking arms 982 (only one shown) directed towards the first drive 3 facing. The two elastic locking arms are intended to elastically engage and hold one of the rollers 32 of the carriage 3 each.

3 FIG. 1 also shows the activatable sealing device 8, which is referred to below with reference to FIG Figures 5a and 5b will be explained in more detail, the assembly device 4, which is below with reference to 4 , Figures 7a and 7b is explained in more detail, as well as the transmission device 6, which is described below with reference to Figures 8a, 8b and 8c is explained in more detail.

4 shows the sliding door 11 of 3 with a view of the facing end face of the door leaf 111. The assembly 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 screwed, has a receiving channel 420, which is delimited by side elements with retaining flanges 421 directed towards one another. The assembly unit 41 is pushed into the receiving channel 420 and is held by the holding flanges 421 . The connecting screw 35 which is screwed into the carriage body 31 of the carriage 3 protrudes between the retaining flanges 421 .

The retaining flanges 421 also have locking depressions 4210 into which a locking tongue 411 of the assembly unit 41 is locked. By lifting the latching tongue 411, the mounting unit 41 can be released and moved within the mounting rail 42 to a further latching position.

In reference to Figure 2a it has already been described that the lever holder 62 can be solved and removed practically with one movement. If the carriage 3 needs to be serviced or adjusted, the locking connections of the assembly unit 41 and the lever holder 62 are released, after which the assembly unit 41 can be extended with the carriage 3. After maintenance or adjustment of the carriage 3, the mounting unit 41 is pushed back into the mounting rail 42 and latched. The lever holder 62 is then reconnected to the mounting base 63 with a flick of the wrist.

Figure 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. By moving the actuating element 82, the leaf springs 141 are bent in such a way that the sealing strip 81, which preferably has an elastic closing element 811, is lifted and pressed elastically against the underside of the running rail 2.

Figure 5b shows the activatable sealing device 8 of FIG Figure 5a after activation by the transmission lever 61 shown symbolically, 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.

Figure 6a shows the buffer device 6 of FIG 1 from the side with the locking part 98, which is anchored on the back by an anchor part 981 in the buffer body 91 and which has two elastic anchor arms 982 on the front, which are bent in order to be able to engage over and hold a running wheel 32 each. Since the activation part 911 is integrated and sunken into the buffer body 91, only its lower part is visible.

Figure 6b shows the buffer device 6 of FIG Figure 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 lock screws 99 are visible on the top. The foot elements 912 of the buffer body 91 are shown on the underside of the buffer device 9 , between which the activation channel 910 is sunk into the buffer body 91 . The channel bottom of the activation channel 910 forms the preferably ramp-shaped activation part 911. Bores are inserted in the ramp 911 into which a screwdriver can be inserted in order to turn the lock screw 99 and the fastening screw 981, by which the locking part 98 is held and pretensioned.

Figure 6c shows the buffer device 6 of FIG Figure 6a in exploded view. It shows that the buffer body 91 has two lateral openings 915 for accommodating the lateral damper 95 , a central opening 916 for accommodating the central damper 96 and a holding lug 918 for holding the anchor part 981 of the locking part 98 . It is symbolically shown that the lateral dampers 95 preferably have a piston 951 which is connected to a piston rod 953 and which is slidably 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 through the Piston 951 is displaced. The piston 951 is preferably returned to the starting position by an elastic element.

Buffer body 91 is preferably made of plastic or metal.

Figure 7a shows the assembly device 4 of FIG 3 and 4 with the mounting rail 42 in which the mounting unit 41 connected to the carriage 3 is held and which is supported on a mounting rail 43 in this preferred embodiment. In a preferred embodiment, the mounting strip 43 can be connected within the door recess 110 to the door leaf 111 of the sliding door 11 and is preferably made of metal. Coupling elements 429, 439 which correspond to one another are provided for easier coupling of the mounting rail 42 to the mounting strip 43. The coupling elements 429, 439 ensure that mutually corresponding mounting holes and threaded holes of the mounting rail 42 and the mounting bar 43 are always aligned coaxially to each other.

Figure 7b shows the assembly device 4 of FIG Figure 7a in an exploded view and with a longitudinal section through the assembly unit 41. The locking tongue 411, which is in Figure 7a is sunk into a detent depression 4210 is exposed at the end and is preferably designed to be elastic. The connection screw 35, which is connected to the carriage body 31 of the carriage 3, is held in a connection channel 410 of the mounting unit 41 in a rotatable manner.

The mounting bar 43, which is in Figure 7b is separated from the mounting rail 42, has mounting openings 430 and threaded holes 431. Self-tapping screws 432 can be passed through the assembly openings 430, by means of which the assembly strip 43 is connected to the door leaf 111. As a result, the mounting rail 42 can be connected to the mounting rail 43 by inserting mounting screws 423 through mounting openings 4230 in the mounting rail 42 and into the threaded holes 431 of the mounting rail 43 . This has the advantage that the mounting bar 43 can be mounted in a simple manner with the required number of self-tapping screws 432 and for the installation of the mounting rail 42 in the Consequence, for example, only two mounting screws 423 are required. The mounting rail 42 can therefore have a simpler design and can be mounted more easily.

Figure 7b shows further that the mounting rail 42 has a plurality of detent depressions 4210 into which the detent tongue 411 of the mounting unit 41 can be depressed. The assembly unit 41 and/or the assembly rail 42 and/or the assembly strip 43 can be made of any material, such as plastic or metal.

Figure 8a shows the transmission device 6 inserted into the door recess 110 from FIG 3 which has a lever bracket 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 panel 111, for example screwed.

Figure 8b shows the transmission device 6 of FIG Figure 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 Figure 6c ) holding the lever shaft 622.

The mounting base 63 has a peripheral retaining flange 631 under which the retaining plate 621 of the lever mount 62 can be pushed. During this process, the holding plate 621 is guided over an elastic latching element 632 which is pushed down before it can latch into the latching recess of the lever mount 62 . By inserting a tool, the latching element 632 can be pushed back down in order to detach the lever mount 62 from the mounting base 63 .

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

9 shows the sliding door system 1 from 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 from FIG US9341011B2 known. In this configuration, mounting unit 41 comprises an adjusting screw 416, which is aligned parallel to the longitudinal axis of the running rail and is rotatably mounted in a mounting body 415, by means of which a carriage holder 417, in which a carriage 418 is mounted so as to be displaceable along guideways, can be displaced axially. When the carriage holder 417 is axially displaced, the carriage 418, which is connected to the connecting screw 416, is displaced up or down along the guideways. Therefore, by turning the adjustment screw 415, the sliding door 11 can be raised or lowered. It is not necessary to remove the mounting unit 41 from the mounting rail 42 for this adjustment process. however, access to the adjusting screw 416 must be guaranteed. To do this, the lever bracket 62 of the transmission device 6 is detached from the mounting base 63, as described above with reference to FIG Figures 8a, 8b and 8c was described.

In this configuration, 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 meets the buffer device 9 .

The buffer device 9 also has a buffer body 91 with an activation channel 910 . In this case, the activation part 911 is not formed 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 in each case. The mounting part 9110 is preferably held in a detachable manner so that it can be detached and reinserted if necessary. In 9 the assembly part 9110 with the activation part 911 is shown after removal and after insertion into the buffer device 9 .
