Description

The present invention relates to a sliding door fitting for a two-leaf sliding door, comprising a above the sliding door wing arranged track with two separate guide grooves with C-shaped cross section, wherein the guide grooves are separated by at least one central web and in the guide grooves in each case two drive parts for each sliding door leaves slidably guided and the drive parts are connected to the sliding door panels attached drive housings and that each sliding door is assigned a self-closing device with a damping assembly through which the sliding door just before reaching their respective closed position acted upon by a prestressed energy storage in the closing direction and attenuated before hitting an end stop ,

Schizbetürbeschläge the generic type are known in many embodiments. For example, from the DE 203 15 124 U1 Such a construction is known in which a Selbsteinzugsvorrichtung with a damping assembly is attached to the outside of a running rail.

EP 1640540 discloses the features of the preamble of claim 1.

The present invention has for its object to further improve a sliding door fitting of the generic type to the effect that this overall has an extremely compact and space-saving design and beyond a total of inexpensive to produce and assemble.

This object is achieved in that the self-closing devices are arranged with the damping assemblies each in a housing, wherein the housing in the front end portions of the rails, in which the at least one central web at least the length of the housing is correspondingly notched out, and within the Cross-section of the running rail lie.

As a result, an extremely compact design of the entire sliding door fitting is initially achieved, since the self-closing devices with the damping assemblies no longer need to be recognized from the outside of the track and thus not protrude beyond the outer contour of the track. On the other hand, it is possible, for example, already in the field of drawers widely used and thus cost available to use self-closing devices with damping assemblies, since they are arranged within a housing and the housing are prepared to be connected to the running rail.

It is provided according to a further, advantageous idea of the invention that the housing are connected by clips connections with the rails.

As a result, a simple and ultimately tool-free connection of the housing and thus also the self-closing devices together with the damping assemblies on the running rail is made possible, which enables the production of a comparatively comfortable sliding door fitting quite inexpensively.

Further features of the invention are the subject of further subclaims.

a partial view of an end region of the guide rail with adjacent self-closing devices with damping assemblies in a common housing

In FIG. 1 , which is to serve only for better understanding and better orientation for the following description, reference numeral 1 denotes a sliding door shown in highly abstracted form, which has two Schiebetürfiügel 2 and 3, which are suspended from a sliding door fitting 4 according to the invention.

The sliding door leaves 2 and 3 are in the viewing direction according to FIG. 1 in two different levels in a row.

The sliding door fitting 4 essentially comprises a running rail 5 arranged above the sliding door leaves 2 and 3 and drive parts to be described, which are displaceable along the running rail 5 and which are connected to the two sliding door wings 2 and 3.

In the FIG. 2 recognizable partial view of an upper portion of a sliding door leaf 2 makes it clear that the sliding door 2 in the region of the upper edge 2a of this sliding door leaf 2 at a distance from each other drive housing 6 are fixed to which drive parts 7 and 8 are firmly connected. The drive parts 7 and 8 are equipped with rollers 9, for example. Instead of the rollers 9 but may alternatively be provided on the Laufverteilen 7 and 8 also sliders.

The rollers 9 - or alternatively provided sliders - engage in approximately C-shaped guide grooves 10 of the running rail 5, as known per se and also from FIG. 7 for example, is recognizable. The two C-shaped guide grooves 10 are separated over the substantial region of the length of the running rail 5 by the stability of the running rail 5 increasing center webs 11 from each other.

These middle webs 11 are so far notched in the end regions of the running rail 5, that in these notched areas a housing 12, preferably by clip connections used and can be fixed, which each receives a self-closing device 13 with a damping assembly 14. Such as the FIG. 5 clearly shows, the housing 12 is provided with locking lugs 15 and locking pins 16 which are provided in recesses provided for the running rail 5 can engage and thereby fix the housing 12 in all possible displacement directions relative to the running rail 5.

The self-closing devices 13 with the damping assemblies 14 are conventional and long-known components, as they are often used for example in drawers use and are cost-effectively available due to the large quantities.

The drive parts 7 are provided with an activator 17 which, depending on the displacement position of a sliding door leaf 2 or 3 with a driver 18 of a self-closing device 13 can be coupled or decoupled. The function of a self-closing device 13 is known per se and will be described at this point only for the sake of clarity that is clamped by the coupling between the activator 17 and the driver 18 when opening a corresponding sliding door leaf 2 or 3, a stored energy whose stored energy when closing the relevant sliding door leaf 2 or 3 is used shortly before reaching the closed position to burden the respective sliding door leaf 2 or 3 in the closing direction. By the damping assembly 14 too violent striking the respective sliding door leaf 2 or 3 is avoided in the closed position.

It is essential in the present invention that the housings 12 with the self-closing devices 13 and damping assemblies 14 arranged therein lie overall within the cross-section of the running rail 5 and thus do not protrude beyond the already existing dimension of the running rail. It is also essential that both the housing 12 and the self-closing devices 13 arranged therein together with damping assemblies 14 are of identical design on both end-side end regions of the running rail 5 and are offset from one another by only 180 ° to the running rail 5. This is from the point of view of a cost-effective production of corresponding sliding door fittings 4 of great advantage.

In principle, the drive parts 7 and 8 of a sliding door leaf 2 or 3 with each other also be identical, but it may also be advantageous if the Drive parts 8, which are not used to operate the respective Selbsteinzugsvorrichtung 13, have no activator 17 and are provided at their opposite direction in the opposite direction front ends with springs 19 which cooperate with integrally formed on the housings 12 brackets 20 to move one into an open position Sliding door 2 or 3 in this open position to fix, as for example in FIG. 6 is shown.

The provided for operating the Seibsteinzugsvorrichtungen 13 drive parts 7 are provided at their opposite ends - in the direction of displacement - deformable in the direction of displacement spring elements 21 which can be used as a damping means in the event that the intended closing position of the respective sliding door leaf 2 or by a malfunction 3 should be run over once.

The running rail 5 is advantageously made in one piece, preferably as a continuous casting profile, it being pointed out at this point that between the C-shaped guide grooves 10, only a central web 11 could be provided.

The construction according to the invention, in addition to the advantage of a cost-effective and assembly-friendly production of a corresponding sliding door fitting 4, also offers the advantage of an extremely compact construction, in particular FIG. 3 also illustrates figuratively that the housing 12 is located entirely within the contour of the track rail 5 and thus does not lead to any disturbing and visually disadvantageous structure of this track rail 5.

The drive parts 8, which are provided with the shaped springs 19, are already known in the market in this design and in this respect also available reasonably priced due to the large manufactured quantities. Only the drive parts 7 with the activator 17 are made specifically for the construction according to the invention.

In this case, the activator 17 may be made in one piece with the drive part 7 as a whole, it is also possible, the activator 17 as a separate To manufacture component and connect, for example by latching connection with the drive part 7.

The drive parts 7 and 8, as well as the housing 12 are preferably made of plastic and thus also inexpensive to manufacture.

In FIG. 11 a sliding door 2 or 3 is shown, which is equipped with a plurality of drive parts, in the concrete embodiment, there are a total of three drive parts 7 and 8, wherein as an external Lauhverkteil on the self-closing and damping device side facing a drive part 7, with an activator is provided is arranged.

The arrangement of three or more drive parts 7 and 8 may be useful in particular with sliding door panels 2 or 3 with a relatively large width, however, always the outer, running for self-closing and damping device drive part must be provided with an activator.

At this point it should be noted that with correspondingly narrow sliding door wings 2, 3, the arrangement of only one drive part 7 is conceivable, especially when the drive part 7 has a relatively large guide width.

The Figures 12 and 13 show an example of furniture 22, which is equipped in the region of its front with a total of three sliding door panels 2 or 3. In this case, the sliding door leaves 2, 3 may be arranged in three different levels one behind the other, as this FIG. 12 shows. In this case, the use of a running rail 5 with a total of three guide grooves 10 is to be used, in each of which at least one self-closing and damping assembly according to the invention can be arranged in the end regions.

As FIG. 13 shows, the total of three sliding door leaves 2, 3 but also be arranged in two different levels one behind the other, in this case, in turn, only one running rail 5 with two guide grooves 10 is required. It can be advantageous in both end regions of each guide groove 10, the housing 12 arranged with the self-closing devices 13 and the damping assemblies 14 and the running in the rear guide groove 10 sliding door 3 on the side facing the furniture side walls are each equipped with a drive part 7. The running in the front guide groove 10 sliding door 2 can be equipped on both sides with the drive part 7 and thereby, provided in non-colliding handles on the sliding door leaves 3, run on both sides of the furniture side walls by means of the device according to the invention.

The advantageous arrangement of two parallel juxtaposed Selbsteinzugsvorrichtungen 13 with the damping assemblies 14 in a common housing 12 'is in FIG. 14 shown. The distances a of the guide grooves 10 must of course be chosen so large in this case that the dimensions of the mirror image of each other Selbsteinzugsvorrichtungen 13 with the damping assemblies 14 allow the juxtaposed arrangement.

In addition to the exemplary embodiments illustrated in the drawings, it is also possible to equip the sliding door leaves 2, 3 with a damping assembly also in the area of their front end edges in the opening direction. In addition, this opening-side damping assembly may be equipped with one of the self-closing device 13 described device, so that even when moving a sliding door leaf 2 or 3 in the opening direction, the final opening position is achieved with power support and fixed in a certain way.

Finally, it should be pointed out that a kinematic reversal of the guidance of the sliding door leaves 2, 3 is possible, ie that the sliding door leaves 2, 3 can be guided with their drive parts 7, 8 in the region of their lower edges on a bottom-side running rail.
