Description

sliding door system

The invention relates to a sliding door system with a sliding door, which is optionally retractable in a parking space.

Sliding door systems comprise at least one sliding door which is suspended from at least two drives guided in a running rail. The rails are fixedly mounted by means of mounting screws on a ceiling or a wall or detachably mounted by means of a fastening device to a mounting profile, which in turn is fixedly mounted on a ceiling or wall.

From US6647590B2 a rail device with a mounting profile is known, which has two provided for receiving a running rail legs, of which the first leg openings for performing connectable with a wall fastening screws and the second leg a T-shaped, open against the running rail Longitudinal slot which serves for receiving and holding locking elements which are connected to mounting screws, by means of which the running rail is mounted.

The mounting profile and the corresponding rail can already be provided during production with holes for the mounting screws. The mounting profile is preassembled, after which the mounting of the track can be done with a few simple steps. A drilling and / or threading for mounting the running rail is eliminated, so that at the same time a contamination or mechanical impairment of the running rail is avoided. This ensures optimal operation of the track and guided therein drives.

The connection of the track with the pre-assembled mounting profile can be done with a few simple steps. The locking elements are for this purpose introduced into the longitudinal slot of the mounting profile, rotated from a first position to a second position and then tightened in the same direction rotating. It is just as easy Loosen and reassemble the track, if access to the locking elements is ensured.

Often, however, sliding door systems include running rails that lead into a parking space bounded by space walls that are built after installation of the running rail and between which a part of the running rail and the sliding door are enclosed after entering the parking space. If repairs to the running rail or components installed therein, such as buffer devices or retraction and / or damping devices should be required, they are therefore hardly accessible and not removable, without degrading or destroying any of the room walls.

US1945332A discloses another device for mounting a running rail. This device comprises a mounting bracket, which comprises the running rail and has a larger cross-section with a free space in which a symmetrically shaped clamp is provided which has two wings. The clamp is held in the middle by a screw. When tightening the screw, the wings of the clamp are pressed down against the running rail, whereby it is fixed. This device therefore requires, in a first step, the retraction of the running rail in the cross section of the mounting bracket and in a second step, the tightening of a screw which is arranged above the running rail, which is undesirable because the screws are hardly accessible above the running rail.

DE10012511A1 discloses a sliding door system with a rail device which comprises a mounting rail mounted in a building, a running rail in which drives connected to a sliding door are displaceably mounted, and a plurality of coupling devices which serve to connect the running rail to the mounting rail. The coupling devices each comprise a mushroom-shaped coupling head, which is connected to the running rail and which is anchored in a coupling opening which is provided in the mounting rail and which is formed in the manner of a keyhole, which is a larger and a Has smaller opening part. To connect the track to the mounting rail, the coupling heads are inserted into the larger part of the coupling opening and moved against the smaller part of the coupling opening to lock the coupling heads. To carry out adjustments or for repairs and maintenance, the running track often has to be dismantled again. In this case, the running rail is moved back until the coupling heads are aligned again coaxially to the larger opening part of the coupling opening. The running rail is usually moved powerfully, so that the coaxial alignment of the coupling heads with the larger opening part of the coupling opening is often successful only after several attempts in which the running track hangs on the mounting rail. It should be noted that the installer stands on a ladder during this work and can not overlook the alignment of the coupling heads relative to the coupling openings. The described operation is therefore associated with considerable effort.

Another device of this type, which requires the same amount of work when mounting and dismounting the track, is described in DE202015105569U1.

The present invention is therefore an object of the invention to provide an improved sliding door system, which is not associated with the disadvantages described.

In particular, a sliding door system is to be provided, in which the running rail can be mounted and dismounted with little effort on a mounting rail.

Vibrations and noises that occur in known sliding door systems during operation should be largely avoided.

The rail device should be advantageously used, in particular in sliding door systems, which have at least one parking space into which the sliding door is slidable. The

Maintenance, repair or replacement of the track rail is intended can be done quickly without parts of the parking space must be dismantled.

Em replacement of the track is to be carried out virtually self-guided, so that the installer does not have to pay attention to an exact alignment and mutual displacement of the track and the mounting rail and mishandling be excluded.

This object is achieved with a sliding door system, which has the features specified in claim 1. Advantageous embodiments of the invention are specified in further claims.

The sliding door system comprises a rail device comprising a mounting rail mounted or mounted in a building, a running rail in which at least two drives connected to a sliding door are guided or routable along a running axis, and a plurality of coupling devices through which the running rail and the mounting profile are detachably connected to each other, and each comprising a coupling head which is connected to the running rail or to the mounting rail having a coupling plate and a coupling neck and which is anchored in a coupling opening which is provided in the mounting rail or the track rail and a first opening part whose diameter is greater than the diameter of the coupling plate, and an adjoining second opening part, whose diameter is greater than the diameter of the coupling neck but smaller than the diameter of the coupling plate. According to the invention, a ramp is provided on one side or on both sides of the coupling head which rises in the direction of the coupling neck against the coupling plate of the coupling head. The preferably at least approximately parallel to the barrel axis aligned and after mounting the first opening part of the coupling opening facing ramp allows to solve the running rail in a simple manner from the mounting rail. Provided that the installed track rail is moved forcefully relative to the mounting rail to align the coupling head and the first opening portion of the coupling opening one above the other, the ramp prevents that the coupling plate can move further over the edge of the first opening part of the coupling opening and hang on the other side below the center piece of the mounting rail. Instead, the ramp hits the edge of the first opening portion and, by sliding over the edge of the first opening portion, slides the coupling plate through the first opening portion of the coupling opening. The process is analogous if the coupling heads are connected to the mounting rail and the coupling openings are provided on the running rail. In a shift of the installed track is thus ensured that the coupling heads smoothly solve the running rail or mounting rail without attaching elsewhere again. The decoupling process is actively supported by at least one of the ramps. The ramp may be an integral part of the coupling head or be part of a device part, which is positively or positively connected to the coupling head.

The ramp can be made of the same material as the coupling heads or of another material. The ramp can be made of plastic or metal or a combination thereof. A plastic-made ramp can be provided on the front side, which faces the edge of the first opening part, with an insert made of metal. With this combination, with respect to the elastic member, the ramp exhibits desirable elasticity when the ramp meets the edge of the first opening portion and, with respect to the metal insert, a desirable strength as the ramp slides over the edge of the first opening portion. In preferred embodiments, therefore, the ramp consists of an elastic element and a metal piece, preferably a metal insert, which is held by the elastic element.

The ramp has an end face which, after installation, faces the edge of the first opening part and which runs straight or along a curve. The width of the ramp is preferably smaller as the diameter of the coupling neck so that it can not form an obstacle when the coupling neck is displaced into the second opening part of the coupling hole. The height of the ramp preferably corresponds to the height of the coupling neck, so that the ramp ends preferably below or subsequently to the underside of the coupling plate.

Slide ramp preferably has the shape of a plate with a sloped face or the shape of a cone segment.

The two opening parts of the coupling opening are preferably rounded, so that the coupling plate of the coupling head can pass as unhindered through the first opening part and still results in the lowest possible weakening of the respective center piece.

The coupling plate of the coupling head can thus be guided through the first opening part of the coupling opening, after which the running rail and the mounting rail are displaced parallel to the running axis against each other such that the coupling neck is inserted into the second opening part and anchored there. The region of the running rail delimiting the second opening part thus serves as a flange, on which the coupling plate guided through the coupling opening is held, so that the coupling plate can no longer retreat through the coupling opening and the connection between the running rail and the mounting rail is created. Finally, the track rail and the mounting rail are preferably mutually blocked or locked, e.g. by passing a bolt or screw through the track and the mounting rail.

After installation of the mounting rail, the running rail can thus be raised against the mounting rail, moved and thus coupled with this and preferably locked. Likewise, the installed track after installation, for example, unlocked again, detected outside of an optionally provided parking space, moved back and released from the mounting rail again. The installation of the mounting rail is done in a known manner, taking care that the mounting rail is aligned horizontally at the selected height.

In a preferred embodiment, the track rail and the mounting rail each comprise a center piece, which is either connected to the coupling head of the coupling devices or provided with the coupling opening. The parts of the coupling devices are thus interchangeable and can be optionally mounted on the running rail or the mounting rail.

The center piece of the running rail is preferably provided on both sides each with a side piece and at least one thereof spaced and parallel thereto extending coupling flange, optionally a flange plate. The first side piece or the first side pieces together with a rail foot, on which the wheels of the drive can be supported, each an L-profile.

The center piece of the mounting rail is preferably also provided on both sides with a side piece, which is preferably dimensioned and aligned so that it can occur during assembly of the rail device in a coupling space between the at least one coupling flange and the adjacent thereto side piece of the track rail. During the process of mounting the running rail, the running rail and the mounting rail can therefore already be provisionally coupled to each other before the coupling heads are inserted and anchored in the coupling openings. This process is greatly facilitated by the provisional coupling.

By means of the at least one coupling flange, it is thus possible to provisionally couple the running rail to the mounting rail in a simple manner and to align it parallel thereto. The coupling heads and coupling openings are aligned along the axis of the barrel and can be moved along the barrel axis in sequence until they can be moved into one another and anchored. Additionally or alternatively, the diameter of the running rail is chosen smaller than the diameter of the mounting rail, so that the running rail can be inserted into the mounting rail and axially displaced along it. The process for coupling and decoupling of the track is therefore performed and can be completed by the installer in a simple manner.

The coupling head can be connected in any way with the running rail or the mounting rail. Preferably, the coupling head or its coupling neck is screwed, cast or caulked. For example, the coupling neck is passed through a corresponding opening in the running rail or the coupling rail so far that an edge beyond the opening protrudes, which is caulked in the sequence (English: press fit stem) and plastically deformed into a flange to form a frictional and create a positive connection. The coupling neck also preferably has a flange element, preferably a flange ring, which bears against the other side of the center piece of the track rail or the mounting rail, which is thus clamped between the shaped flange element and the flange ring. The coupling head may also be fastened with a screw, e.g. held axially in an internal thread of the coupling neck and rests with the screw head on the center piece of the running rail or the mounting rail. Alternatively, the coupling neck itself may have a thread which is screwed into the opening in the running rail or the mounting rail in which a thread provided or a threaded member is inserted.

The coupling head can be designed rotationally symmetrical and m easy to assemble. Alternatively, a segment of the coupling head or the coupling plate may be cut away at the relevant side, so that the coupling plate can not hang on the mounting plate during the deinstallation. With a corresponding embodiment of the coupling head can be dispensed with an additional ramp. In a further preferred embodiment, a buffer device is provided, which has the at least one ramp and / or at least one elastic element, by means of which the coupling head after the connection of the running rail with the mounting rail elastically coupled to the center piece of the running rail or the center piece of the mounting rail becomes. As a result, any play between mounting rail and track is canceled. The preferably made of plastic buffer device also direct contact between the running rail and the mounting rail and thus metallic rattling noise are avoided in the operation of the sliding door.

The buffer device preferably comprises a plate-shaped part with a recess which serves to receive the coupling neck of a coupling head. In this case, the buffer device can be connected to the coupling head such that the elastic elements or spring elements are arranged laterally next to the coupling head and / or that the ramps are arranged along the running axis on the front side or the rear side of the coupling head.

The at least one elastic element and / or the at least one ramp are preferably integrally connected to the buffer device. Alternatively, the elastic element and / or the ramp may be e.g. By means of a latching connection are also positively connected to the buffer device.

The at least one elastic element and / or the at least one ramp are preferably aligned parallel to the barrel axis, so that they unfold during the mutual displacement of the track rail and the mounting rail an optimal effect and are loaded only on pressure, but not on torsion.

In a further preferred embodiment, the coupling head has a central bore through which a fastener, such as a screw, can be passed, e.g. around the track rail or mounting rail, electrical devices, such as

Power supply lines for motorized drives, etc., attach. The coupling head is preferably rotatably held in the associated center piece, so that it can not be solved automatically from the center piece. This is achieved particularly easily by providing the coupling neck and the opening corresponding thereto in the center piece of the running rail or the mounting rail with a polygonal cross section. Alternatively, a

Locking device can be used. For example, will the

Buffer device rotatably connected to the associated center piece and rotatably connected to the coupling head and provided with locking elements which are positively connected to the running rail and the coupling head. The connection between the buffer device and the coupling head is advantageously carried out by means of said ramp, which engages positively in a recess provided in the coupling head and holding elements which are positively connected to the running rail or the mounting rail.

The coupling head and / or the buffer device are preferably made of metal or plastic, preferably hard plastic. Preferably, a thermoplastic such as polyoxymethylene (POM) is used which has high strength, rigidity, and good sliding properties.

The buffer device may also be made of an elastomer or of a natural rubber, which is preferably provided with a coating which gives the surface of the buffer device excellent sliding properties and facilitates rail mounting.

In a further variant, it is possible to use between the coupling head and the buffer device optionally a sound-absorbing element which consists of an elastomer or of a natural rubber and allows improved sound decoupling between the mounting profile and the running rail. The ring-shaped sound-absorbing element, for example, can be softer by a multiple than the material of the buffer device. In a further preferred embodiment, it is provided that the coupling opening adjoins a coupling channel which is bounded by the middle piece of the running rail as well as spaced channel strips which are aligned within the running rail parallel to the middle piece against each other and each connected to one of the side pieces of the running rail. The coupling plate can therefore be introduced through the coupling opening in the coupling channel and there held preferably free of play by means of the elastic elements.

The invention will be explained in more detail with reference to a drawing. Showing:

1a shows a sliding door system according to the invention with a parking space 7, into which a rail device 10A according to the invention is guided, which comprises a mounting rail 2A and a running rail 1A detachably connected thereto. The front piece of the running rail 1A is cut away slightly outside the parking space 7, so that the guided in the running rail drives 63 are visible, which are connected via door fittings 61 with a sliding door 6. The parking space 7 is bounded on both sides by room walls 71, 72, which were permanently installed after assembly of the mounting rail 2A and only with great effort are solvable. A manual intervention in the space opening 70 of the parking space 7 is no longer possible after the installation of the room walls 71, 72.

The mounting rail 2A was installed at the desired height in horizontal alignment by means of mounting screws 91 on the ceiling of the room.

Subsequently, the drives 63 and optionally a buffer device (not shown) were inserted into the slide rail 1A, which was connected in sequence by inventive coupling devices with the mounting rail 2A. Finally, the sliding door 6, e.g. a glass door or a wooden door, connected by means of the door fittings 61 with the displaceably mounted in the slide rail 1A drives 63.

Fig. Lb shows an example that the sliding door 6 is made of wood and provided at the upper corners with recesses 60, in each of which a door fitting 61 is inserted, which includes a fitting rail 611 and a fitting block 612 inserted therein. The fitting block 612 is connected by a threaded rod 62 with the associated drive 63, the wheels 631 can roll on both sides in each case on a rail foot 13 of the running rail 1A in the running rail 1A. The drives 63 and the sliding door 6 are therefore displaceable along a running axis x and can in the parking space 7 are retracted. As mentioned, the slide rail 1A has been partially cut away to show the drive 63 and the door fitting 61.

1c shows the rail device 10A removed from the sliding door system of FIG. 1a, the front quarter of which has been cut away in order to fully show the coupling devices comprising coupling heads 3A connected to the mounting rail 2A and coupling openings 4A provided in the rail 1A. The coupling heads 3A that can be anchored in the coupling holes 4A will be described in detail below.

The running rail 1A has a downwardly open U-profile with a central piece 12, which is connected on both sides with side pieces 11, each forming an L-profile with oppositely directed Fußstücken 13. The side pieces 11 are also each connected by web elements with a flange plate 111 extending parallel thereto.

The mounting rail 2A has an H-profile with a central piece 22, on both sides of the side pieces 21 are provided. The distance between the side pieces 21 of the mounting rail 2A is greater than the distance between the side pieces 11 of the rail 1A, but smaller than the distance between the flange plates 111 of the rail 1A.

As shown in Fig. 2a, a coupling space 110 is formed between each flange plate 111 and the associated side piece 11, in which the associated side piece 21 of the mounting rail 2A can be inserted. The flange plates 111 project beyond the center piece 12 of the track rail 1A and thereby facilitate the coupling to the installed mounting rail 2A.

Below the central portion 12 of the track rail 1A, the coupling openings 4A open into a coupling channel 15, which is partially bounded by the center piece 12 of the track rail 1A and two channel strips 16 which are aligned at the same height each with one of the side pieces 11 are connected. Between the channel strips 16, a space is kept open, which allows to engage with a tool in the coupling channel 15.

The coupling head 3A is preferably held against rotation in an opening 28, e.g. screwed, caulked, welded or potted. Fig. 2b shows the rail device 10A of Fig. Lc after the connection of the rail 1A with the mounting rail 2A. The coupling plate 32 of the coupling head 3A was inserted into the coupling channel 15, and the center piece 12 of the track rail 1A is held between the side pieces 21 of the mounting rail 2A. The running rail 1A is therefore displaceable only parallel to the running axis x or parallel to the longitudinal axis of the rail device 10A. This facilitates the operation of coupling and decoupling the track rail 1A from the coupling heads 3A of the mounting rail 2A.

Fig. 3a shows one of the coupling heads 3A of Fig. Lc. Fig. 3b shows the coupling head 3A of Fig. 3a cut along the line A-A. Fig. 3c shows the coupling head 3A of Fig. 3a from below. Fig. 4 shows a part of the rail device 10A of Fig. Lc in a three-dimensional view with a section through the longitudinal axis of the mounting rail 2A. The coupling head 3A has a coupling neck 31 which includes a connecting piece 311 and a spacer 312. The connecting piece 311, which has a smaller diameter than the spacer 312, is formed as an octagon and serves to pass through a correspondingly formed octagonal opening 28 in the middle piece 22 of the mounting rail 2A. After insertion into the octagonal opening 28, the top of the spacer 312 forms a flange ring which bears against the underside of the center piece 22. The upper end portion 310 of the connecting piece 311 protrudes in the sequence from the octagonal opening 28 (see also Fig. 9) and can be caulked, ie plastically deformed, so that the connector 311 below the spacer 312 and above the caulked end piece 310 axially immovable the octagonal opening 28 is held. Due to the octagonal configuration of the connecting piece 311 and the opening 28, the connecting piece 311 and thus the entire coupling head 3A also rotatably held.

The coupling neck 31 is followed by a round coupling plate 32 intended for insertion into the coupling channel 15 (see FIG. 4). Fig. 3b shows that an axial bore the entire

Passing coupling head 3A passes, which can be made with an internal thread.

Fig. 4 shows the coupling opening 4A, which is provided in the center piece 12 of the rail 1A and which comprises a larger first opening portion 41 and a smaller second opening portion 42. The larger opening part 41 is adapted to the size of the coupling plate 32, which can be inserted at this point through the coupling opening 4A into the coupling channel 15. Subsequently, the running rail 1A can be moved relative to the mounting rail 2A and thereby anchored. In this case, the spacer 312 is preferably received by the second opening part 42 without play. On the other hand, the coupling plate 32 is held below the second opening part 42, the adjacent edges of which form a retaining flange. The guide rail 1A is therefore connected to the mounting rail 2A and can only be released again by the first opening part 41 is moved back over the coupling plate 32. Through an additional opening 18 in the slide rail 1A, a bolt or another fixing screw 91 can be passed therethrough to lock the anchored rail 1A against the mounting rail 2A.

Thus, the rail 1A is held without play after anchoring to the coupling head 3, preferably one or more elastic elements, preferably spring elements, such as leaf springs are provided. So that the coupling head 3A particularly easy again from the

Coupling opening 4A can be solved, according to the invention at least one ramp is provided, which connects to the coupling head 3A. The at least one elastic element and / or the at least one ramp may be integrally connected to the coupling head 3A or integrally formed thereon. Preferably, a buffer device is provided on which the at least one elastic element and / or the at least one ramp is provided.

5a shows the coupling head 3A of FIG. 3a with a buffer device 5A connected thereto, which has spring elements 51 on both sides and a respective ramp 52 on the front and back. Fig. 5b shows the coupling head 3A of Fig. 5a with the associated buffer device 5A from below.

Fig. 6a shows the buffer device 5A of Fig. 5a from above and Fig. 6b shows the buffer device 5A of Fig. 6a from below.

The buffer device 5A consists of a rectangular buffer plate 50 which has in the center an opening 500 which serves to receive the coupling neck 31 of the coupling head 3A, as shown in Fig. 5a. On opposite sides, the buffer plate 50 has downwardly directed elastic elements or spring elements, which are formed as leaf springs, which are held on both sides. The spring elements 51 were formed from the buffer plate 50 and are aligned parallel to each other. Alternatively, the spring elements 51 can be kept on only one side. On the underside of the buffer plate 50 is front and back each provided with a ramp 52, both of which, seen from below, rise against the opening 500 out. In Fig. 5a it is shown that the spring elements 51 and the ramps 52 of the coupling plate 32 are facing the coupling head 3A, so that they can cooperate with the held by the center piece 12 of the rail 1A and the coupling opening 4A enclosing edge of the center piece 12 , Fig. 7 shows the rail device 10A of Fig. 4 with the on the

Coupling head 3A patch buffer device 5A of Fig. 5a. The

Buffer plate 50 is located on the center piece 22 of the mounting rail 2A and provided thereon spring elements 51 and ramps 52 are the Centerpiece 12 of the track rail 1A faces. The mounting rail 2A is cut along the longitudinal axis so that the installed coupling head 3A is visible with the buffer device 5A.

Fig. 8a shows the rail device 10A of Fig. 7 with the rail 1A separated from the mounting rail 2A. Fig. 8b shows the rail device 10A of Fig. 8a after the coupling of the slide rail 1A to the mounting rail 2A. The buffer plate 50 is held above the center piece 12 of the slide rail 1A and presses this with the non-visible spring elements 51 backlash against the coupling plate 32 of the coupling head 3A, which is held by means of channel strips 16 within the coupling channel 15.

FIG. 9a shows in a spatial representation a part of the rail device 10A of FIG. 8b with a section along the longitudinal axes of the running rail 1A and the mounting rail 2A. It can be seen that the polygonal or preferably octagonal connecting piece 311 of the coupling neck 31 is held in a rotationally fixed manner in the polygonal or preferably octagonal opening 28 in the center piece 22 of the mounting rail 2A. The upper end portion 310 of the connecting piece 311 of the coupling neck 31 protrudes beyond the center piece 22 of the mounting rail 2A and can be plastically deformed by caulking into a flange member. The buffer plate 50 of the buffer device 5A is located on the underside of the center piece 22 of the mounting rail 2A and presses with the spring elements 51 against the top of the center piece 12 of the rail 1A. The coupling plate 32 of the coupling head 3A has been inserted into the coupling channel 15 through the coupling hole 4A and is slightly above the channel strip 16. The ramps 52 are aligned parallel to the rail axes and prevent the coupling plate 32 from being under the edge of the middle 12 at the front or rear the running rail 1A can be driven. The coupling plate 32 is still below the first opening portion 41 and is displaced by moving the guide rail 1A in the direction of the arrow shown below the second opening portion 42 of the coupling opening 4A and anchored there. Through the opening 18 in the slide rail 1A, a locking element against the mounting rail 2A can be performed. Fig. 9b shows the part of the rail device 10A of Fig. 9a with a section along the longitudinal axis through the mounting rail 2A and a section through the closer left quarter of the buffer device 5A. The left ramp 52 is therefore shown in a sectional view and the left side of the spring element 51 has been cut away. It is shown that the underside of the coupling plate 32 of the coupling head 3A connects to the ramp 52 or to the side which faces the coupling neck 31. In this preferred embodiment, the height h52 of the ramp 52 therefore corresponds approximately to the height h31 of the coupling neck 31 and is therefore smaller than the height h3A of the coupling head 3A.

The ramp 52 has an end face 521 which is inclined relative to the running axis x at an angle which is preferably in a range between 40 ° and 60 ° and more preferably about 45 °. The carriage side 521 is preferably located outside the radius r32 of the coupling plate 32 and preferably terminates at the periphery of the coupling plate 32. The end face 521 therefore extends from the end point of the radius r32 of the coupling plate 32 to the end point of the radius r52 of the buffer device 5A, respectively the central axis y of the coupling head 3A in a direction parallel to the running axis x.

10a shows the rail device 10A of FIG. 9 with the coupling head 3A anchored in the second opening part 42 of the coupling opening 4A. The front-side ramp 52 of the buffer device 5 abuts the edge of the coupling opening 4A and prevents the coupling plate 32 in the direction of the axis X from getting under the center piece 12 of the track rail 1A.

FIG. 10b shows the rail device 10A of FIG. 10a with the coupling head 3A displaced into the first opening part 41 of the coupling opening 4A. In this position, the rear ramp 52 abuts the edge of the coupling opening 4A and prevents the coupling plate 32 in the direction of the axis X can get under the centerpiece 12 of the slide rail 1A. When moving the slide rail 1A, the coupling head 3A is thus out of the anchoring in the second Opening part 42 of the coupling opening 4A solved and moved into the first opening part 41, after which the slide rail 1A can be taken down without the coupling plate 32 can hang on the center piece 12 of the slide rail 1A. 11 shows a rail device 10B according to the invention in a second preferred embodiment. The front quarter of the rail device 10B has been cut away to show the elements of the coupling devices that have coupling heads 3B connected to the track rail 1B that can be anchored in coupling holes 4B in the mounting rail 2B.

The running rail 1B is designed simpler and has only a central piece 12 and on both sides provided thereon side pieces 11, which together with one foot piece 13 form an L-profile. On the middle piece 12, the coupling heads 3 B are arranged and held against rotation.

The mounting rail 2B has a downwardly open U-profile with a central piece 22 in which the coupling openings 4B are provided. On both sides of the central piece 22 side pieces 21 are provided, whose mutual distance is greater than the mutual distance of the side pieces 11 of the rail IB. The running rail 1B can therefore be received in the U-profile of the mounting rail 2B, whereby the coupling of the running rail 1B is facilitated to the mounting rail 2B.

The coupling openings 4B, which are provided in the center piece 22 of the mounting rail 2B, corresponding to the coupling openings 4A in the track rail 1A, for example, as shown in FIG. 4 and also have a larger first opening portion 41 and a smaller second opening portion 42 which form approximately the shape of a keyhole , The first opening part 41 is, for example, approximately circular and the second opening part 42 is elongated or at least approximately rectangular and preferably rounded. The coupling of the rail 1B with the mounting rail 2B is carried out in the same manner as described above, only the coupling devices inserted inversely in the rail device 10B, which is why there is a kinematic reversal.

FIG. 12a shows one of the coupling heads 3B of FIG. 11 and a buffer device 5B connected thereto, which is likewise provided on the front side and the rear side with a ramp 52 and on both sides with spring elements 51. Fig. 12b shows the coupling head 3B and the buffer device 5B cut along the section line B-B shown in Fig. 12a. Fig. 12c shows the coupling head 3B and the buffer device 5B of Fig. 12a in an exploded view. The ramps 52 connected to the buffer device 5B, as in the embodiment of FIG. 10b, prevent the coupling plate 32 of the coupling head 3B from hitting the center piece 22 of the mounting rail 2B in the direction of the running axis X during disassembly of the running rail 1B. In addition, the ramp 52 serves to hold the coupling head 3B against rotation. For this purpose, the buffer device 5B on both sides of holding elements 55, which grip the center piece 12 of the track rail 1B on both sides and thereby hold the buffer device 5B and the ramps 52 rotatably. The ramps 52 each protrude into a retaining groove 321 in the coupling plate 32 of the coupling head 3B, whereby the coupling head 3B is fixedly coupled to the running rail 1B and held rotatably.

FIGS. 12a and 12b show that the spring elements 51 are integrated into the buffer plate 50 and are slightly curved against the coupling plate 32.

Fig. 12b shows that between the coupling plate 32 of the coupling head 3B and a support plate 58 of the buffer device 5B optionally an elastic damping element 59 is provided which is annular and made of a resilient plastic material. The support plate 58, the damping element 59 and the coupling plate 32 form a unit and are integrated as a unit by an associated coupling opening 4 B in the middle piece 22nd the mounting rail 2B guided and anchored, as shown in Fig. 13.

The guided through an opening 500 in the damping element 59 and in the support plate 58 coupling neck 31 has an internal thread into which a mounting screw 93 is screwed. By means of the mounting screw 93, the coupling head 3B and the buffer device 5B are bolted to the center piece 12 of the track rail 1B.

Fig. 13a shows the rail device 10B of Fig. 11 with the rail 1B separated from the mounting rail 2B connected by the mounting screw 93 to the coupling head 3B and the buffer device 5B.

Fig. 13b shows the rail device 10A of Fig. 13a after the coupling of the rail 1B to the mounting rail 2B. The track rail 1B was lifted and, after the insertion of the coupling head 3B, shifted parallel to the barrel axis x through the first opening portion 41 of the coupling hole 4B, thereby guiding and anchoring the coupling neck 31 of the coupling head 3B into the second hole portion 42 of the coupling hole 4B. In this position, the elastic members 51 (not visible) abut the underside of the center piece 22 of the mounting rail 2B and at the top thereof, via the second opening portions 42, the coupling unit is held by the support plate 58, the damping member 59 and the coupling plate 32 is formed. The coupling plate 32, which is screwed to the center piece 12 of the track rail 1B is therefore separated by the elastic member 59 of the support plate 58, which rests against the center piece 22 of the mounting rail 2B. The mounting rail 2B is therefore elastically held from above by the damping element 59 and from below by the spring elements 51 and decoupled from the running rail 1B. Running noises caused by the drives 63 when the sliding door 6 is displaced are not transmitted to the mounting rail 2B and the building by the running rail 1B. Fig. 14 shows the track rail 1B of Fig. 11 with two coupling devices 3B installed thereon, each provided with a modified buffer device 5B *. Along the symmetry axis, a cut was made through the rear part of the track rail 1B and through the rear coupling device 3B. The buffer device 5B * again has a buffer spring 51 and a buffer ramp 52, which serve the described purposes. On the other hand, only one holding element 55 is provided, which is held in the form of a mandrel in an opening 121 in the middle piece 12 of the running rail 1B. Holding elements, which project beyond the running rail 1B laterally, can be avoided.
