Description

Sliding door fitting with a buffer locking device

The invention is based on a sliding door fitting with a carriage guided in a stationary, preferably horizontal guide rail for suspending a door leaf or the like, with a locking buffer device.

In a known sliding door fitting of this type (DE-OS 33 36 565), the locking buffer device consists of an elastic block attached to the guide rail, which interacts with a conical mandrel attached to the carriage to dampen the impact and lock the sliding door. The conical mandrel is inserted into the circular receiving hole in the elastic buffer block.

The disadvantage of this design is that it has a certain rebound effect and is not firmly fixed in the end position. Furthermore, precise centering of the buffer block and mandrel is required.

~..;- The invention is based on the task of developing a locking buffer that makes it possible for the movement to be buffered in the end position, intercepted without rebounding and for a good locking in the end position to be achieved.

This object is achieved in that, in a sliding door fitting of the type mentioned at the outset with a locking buffer device which has a stop member attached to the carriage or fixed in place, in particular to the guide rail, and a receptacle which is fixed in place or attached to the carriage and which at least partially receives and encloses the stop member in the stop position, wherein the receptacle and/or the stop member is or are elastically deformable when they interact, it is provided according to the invention that the receptacle has a receiving gap with an elongated receiving opening.

Preferably, the part of the stop member which engages in the receiving gap in the stop position is designed as a nose, the cross section of which corresponds to the receiving opening. The height of the nose is less than the length of the gap opening, so that centering is not a problem. The active surfaces on the nose, which interact with the inner surfaces in the receiving gap, can be selected to be relatively large.

In preferred embodiments , the nose can be essentially flat, cuboid-shaped. In this case, a conical shape of the nose can be dispensed with. Preferably, the nose can have at least one bead running transversely to the direction of movement of the carriage or transversely to the guide rail. By enclosing the bead in the receiving gap, a particularly good hold in the locking mechanism is achieved.

In the various designs, the receiving gap and/or the part of the stop member that extends into the receiving gap, e.g. the nose, can be elastically deformable when they work together in the stop position. In preferred designs, the receiver is elastic and the nose is rigid. The receiving gap can be formed between two elongated elastic receiving lips. In order to achieve a particularly good hold in the locking device, it can be provided that the part of the stop member that engages in the receiving gap in the stop position, e.g. the nose, is arranged between two rigid pincer-shaped jaws. The jaws can have wedge surfaces on the sides facing each other. In the stop position, the jaws act on the outside of the elastic receiving lips and press the lips together. This results in a narrowing of the gap, which becomes more pronounced due to the wedge surfaces the further the stop member extends into the receiving gap.

Further advantages also arise when adjusting the ;

Locking buffer device, especially if the stop element and/or the holder are attached using clamping screws.

In the following, an example embodiment is explained in more detail with reference to the figures.

Figure 1 is a schematic front view of a sliding door fitting with guide rail, carriage and locking buffer device;

Figure 2 is a plan view of Figure 1, with the locking buffer device partially sectioned.

The sliding door fitting shown consists of a guide rail 1, a carriage 2 and a buffer device 3.

In the embodiment, the guide rail 1 is attached horizontally to the wall or ceiling. The carriage 2 is guided on rollers in the rail 1. It has a plate-shaped body 4 in which two lower rollers 5, 6 and an upper guide roller 7 are mounted in ball bearings. The lower rollers 5, 6 run on a lower running surface 8, the upper guide roller on an upper running surface 9 of the guide rail.

A support screw 10 is attached to the lower angled edge of the carriage body 4 for suspending a sliding door leaf (not shown).

The locking buffer device 3 consists of a block 11 fastened in the rail 1 with an elastic gap-shaped holder 13 and a stop member 14 attached to the carriage with a protruding rigid retaining lug 15. In the stop position (not shown), the retaining lug 15 engages in the elastic holder 13.

The Blo2k 11 is inserted into the guide rail 1 and is clamped there using clamping screws. It is supported by a lower and an upper bearing surface 21 and 22 on the lower and upper running surface 8 and 9 of the guide rail 1. The two clamping screws 16, 17 are screwed into the lower section of the block 11 and the clamping screw 18 is screwed into the upper section: their ends are supported on the rear wall of the guide rail 1.

The mounting block 11 can be clamped in any position along the guide rail using the clamping screws 16, 17.

By adjusting the lower clamping screws 16, 17 to the upper clamping screw 18, it is possible to adjust the block 11 around a central horizontal axis.

By appropriate adjustment of the two lower clamping screws 16, 17 relative to each other, an adjustment ^of _a ^{vertical axis} is possible.

22 are concave with a larger radius of curvature than the convex running surfaces 8, 9 with which they interact.

The receptacle 13 is designed as a gap that is delimited by two elastic lips 23, 24. The gap with the lips 23, 24 is formed by a U-shaped rubber tab 25, which is inserted into a receiving pocket 26 in the block 11. To secure the rubber tab 25 in the block 11, two pins 27 are provided that engage in the block 11 and pass through the U-legs of the tab 25 near the U-bridge.

The receiving pocket 26 has on the front side on both sides of the lips 23, 24, i.e. on the front and back of the block 11, outwardly open extensions 30 into which pincer-shaped jaws 28 of the stop member 14 can engage in the stop position.

The stop member 14 is screwed to the carriage body 4. The screws pass through the L-shaped base body of the stop member 14. The retaining lug 15 is designed as a protruding, essentially flat cuboid-shaped web on the front side of the stop member facing the receptacle 13. It has a height 15 h, which is slightly less than the height 13 h of the gap 13. In cross-section it is elongated, as shown in Figure 2, with the width 15 b corresponding to the clear width 13 w of the gap opening. In the illustrated embodiment, the free front end of the lug 15 has a bead-shaped thickening 35 running vertically, i.e. transversely to the direction of movement, the diameter or width of which is slightly larger than the gap width 13 w. The width 15 b of the remaining lug 15 is approximately equal to the gap width 13 w.

On both sides of the nose 15 at the front and back, a jaw 28 is formed on the stop member 14. The jaws 28 are slightly shorter than the nose 15 when viewed in the direction of movement. They each have a wedge surface 29 facing the nose 15. The wedge surfaces 29 diverge towards the free end.

The receiving block 11 is arranged in the guide rail 1 in such a way that in the stop position, when the nose 15 engages in the gap 13, the sliding door is in a predetermined end position, e.g. in the closed position or open position.

The end position is set by moving the door into this position by hand or by means of a motor drive. The interaction of the stop member 14 with the elastic holder 13 ensures that the stop is dampened and the sliding door is secured in the stop position.

When the nose 15 enters the receiving gap of the elastic holder 13, the movement is slowed down and stopped in a buffer-like manner by the friction between the nose 15 and the lips 23, 24 and by elastic deformation of the lips 23, 24. The lips 23, 24 enclose the nose 15 and thus also ensure that it is locked in the stop position.

By including the bulge-shaped thickening 35 , a grip in the gap and thus a particularly firm hold is achieved.

If the sliding door is moved into the stop position with more momentum or greater force, the nose 15 plunges further into the holder 13 so that the wedge surfaces 29 of the pincer-shaped jaws 28 interact with the outside of the lips 23, 24 and press the lips 23, 24 together. This narrows the gap in the holder 13 and increases the hold of the nose 15 in the holder. The further the nose 15 plunges, the more the lips 23, 24 are pressed together by the jaws 28 and the stronger the holding point becomes.

The stop member 14 with the stop 15 is then released from the elastic holder 13.
