Description

DESCRIPTION

Sliding door fitting and corresponding sliding door arrangement

The invention relates to a sliding door fitting for at least two sliding doors that can be arranged in parallel.

Such sliding door hardware is widely known, but usually consists of many individual parts and is therefore expensive, complex to build, heavy, massive, takes up a lot of space, mechanically vulnerable and difficult to orient.

From EP 0712989 A1 a sliding door fitting for two sliding doors that can be arranged in parallel is known. The sliding door fitting comprises an upper and a lower sliding rail, each having a guide groove, and in each case two upper and two lower spring runners for each of the sliding doors. The spring shoes each have a pin spring with a first spring pin that bears against a groove flank of the guide groove and a second spring pin that carries a compression arm. The free end of the compression arm will bear against the other groove flank of the guide groove and can be deflected from an initial position against the elastic force of the pin spring to an end position in which the free end of the compression arm it is at a shorter distance from the first spring pin than in the initial position.

On the contrary, the present invention is based on the objective of specifying a sliding door fitting that is as simple as possible, in particular for small furniture.

This objective is achieved by a sliding door fitting for at least two sliding doors that can be moved in parallel, with an upper and a lower sliding rail, each having a guide groove, and with at least two runners in each case. upper and two lower spring runners for each of the sliding doors, wherein the spring runners are each made of a single piece of plastic and each have a base body with two opposite longitudinal edges, one of which , the first longitudinal edge, will rest against one groove flank of the guide groove, and a spring arm formed in the base body, the free spring arm end of which will rest against the other groove flank of the guide groove, where the spring arm can be deflected from an initial position, in which the free spring arm end protrudes beyond the other second longitudinal edge, against the action of a restoring force, into an end position that protrudes less , and where the distance between the two longitudinal edges of the base body is at most half the slot width of the guide slot, so that two spring-loaded sliders fit parallel to each other on the slide rail.

The sliding door fitting according to the invention has few, cheap and light parts that are not prone to failure or complicated to assemble. According to the invention, the spring sliders are made of a single piece of plastic, so that the restoring force of the spring arm is caused by its elastic deformation.

Preferably, the base body has a recess at its second longitudinal edge into which the end of the free spring arm engages at least partially in the end position.

Particularly preferably, the base body has at least two pegs spaced in the longitudinal direction on its mounting side, which are pressed into corresponding holes in the bottom or top of the sliding door. Advantageously, the different distances between pins can avoid incorrect positioning of the lower and upper spring shoes. Preferably, the lower and upper spring shoes are mirror-symmetrical to one another, if necessary except for different pin spacing.

Particularly preferably, the spring arm has a longitudinal edge that protrudes beyond the mounting side of the base body, so that it can also be deflected by a sliding door that is displaced in front of it.

The invention also relates to a flush-closing sliding door arrangement with at least two sliding doors that can be arranged in parallel and with a sliding door fitting configured as above, where each of the sliding doors is guided in a longitudinally displaceable manner. in the guide groove of the lower slide rail by means of two lower sliders mounted on the bottom and in the guide groove of the upper slide rail by means of two upper spring-mounted shoes mounted on the top.

Additional advantages of the invention appear from the description, from the claims and from the drawing. The embodiments shown and described are not to be understood as an exhaustive enumeration, but are rather exemplary in order to illustrate the invention.

Show:

1 an embodiment of a sliding door fitting according to the invention with sliding rails and spring runners, which are partly mounted on a sliding door;

figure 2 a perspective view of the spring shoe shown in figure 1; and

Figures 3a-3e the sequence of movements of a flush-closing sliding door arrangement with two sliding doors that can be positioned in parallel when one of the two sliding doors is opened.

The sliding door fitting 1 shown in FIG. 1 is used for parallel placement of two sliding doors 13a, 13b of a flush-closing sliding door arrangement 12 of a sliding door cabinet shown in FIG. 3a and is particularly suitable for small furniture.

The sliding door fitting 1 comprises an upper and a lower U-shaped sliding rail 2a, 2b, each with one guide groove 3 and two upper and two lower spring sliders 4a, 4b for each of the two sliding doors. sliding doors 13a, 13b. As shown in FIG. 2, the spring shoes 4a, 4b each have a flat base body 5 with two opposite longitudinal edges 6a, 6b, one of which, the first longitudinal edge 6a, will rest on a flank of groove 3a of the guide groove 3, and a spring arm 7 articulated to the base body 5, whose free spring arm end 7a will rest against the other groove flank 3b of the guide groove 3.

The spring shoes 4a, 4b are each made of a single plastic part, ie the spring arm 7 is formed on the base body 5 and can be elastically deflected. The spring arm 7 can be elastically deflected from the initial position shown in FIG. 1 for the upper spring shoes 4b, in which the free spring arm end 7a protrudes outwards beyond the other second longitudinal edge 6b , inwards to the least protruding end position, shown in figure 2. As long as the spring shoes 4a, 4b have not yet been inserted into the U-shaped slide rails 2a, 2b, the distance a between the end of free spring arm 7a and the first longitudinal edge 6a is greater than the slot width B of the guide slot 3 in the initial position. The base body 5 and the spring arm 7 are arranged in the same plane, whereby the base body 5 has a recess 8 in its second longitudinal edge 6b, into which the free spring arm end at least partially engages. 7th in the final position. The spring arm 7 also has a longitudinal edge 9 which protrudes beyond the mounting side 10 of the base body 5. In the final position, the longitudinal edge 9 preferably runs parallel to the first longitudinal edge 6a.

On the mounting side 10 of the base body 5, two pins 11 offset in the longitudinal direction, in particular shaped, are provided. Preferably, the distances between pins of the lower and upper spring shoes 4a, 4b are different and the lower and upper spring shoes 4a, 4b have mirror symmetry with respect to each other, except for these different distances between pins. The longitudinal edges 6a, 6b can run parallel or, as shown in the exemplary embodiment, also slightly oblique to one another. The distance b between the two longitudinal edges 6a, 6b of the base body 5 is at most half the slot width B of the guide slot 3.

In figures 3a-3e the sequence of movements of the arrangement of sliding doors 12 of closing in line with two sliding doors 13a, 13b that can be placed in parallel when opening the sliding door 13a is shown, the left one in figures 3a-3e . The two sliding doors 13a, 13b are guided so that they can be moved longitudinally in each case in the guide groove 3 of the lower sliding rail 2a by means of two lower spring shoes 4a mounted on the bottom and in the guide groove 3 of the sliding rail. upper sliding 2b by means of two upper spring sliders 4b mounted on the upper side. The base body 5 rests with its first longitudinal edge 6a on one groove flank 3a and the outwardly preloaded spring arm 7 rests with its free spring arm end 7a on the other groove flank 3b, so that the sliding door 13a, 13b is guided longitudinally along the slide rails 2a, 2b. The slide rails 2a, 2b are mounted, for example, on the bottom and on the top of a cabinet body, in particular grooved.

Figure 3a shows the two sliding doors 13a, 13b in their frontally aligned closed position, in which the two sliding doors 13a, 13b rest against each other.

When the right side of the left sliding door 13a is pressed inwards (direction of the arrow), the spring arms 7 of the right spring shoes 4a, 4b of the left sliding door 13a are deflected in each case to their final position. , against its elastic recovery force. The right side of the left sliding door 13a together with the right spring shoes 4a, 4b move transversely in one plane behind the right door leaf 13b and then laterally move both behind the left door side of the right door leaf 13b as well as behind the left spring shoes 4a, 4b of the right sliding door 13b in the opening direction, ie to the right (FIG. 3b). As shown in the exemplary embodiment, the mutually facing front faces 14 of the base body of the spring runners 4a, 4b displaced past one another of the two sliding doors 13a, 13b can run obliquely to cause a combined transverse and longitudinal movement when oblique pressure is applied to the right side of the left sliding door 13a.

When the left sliding door 13a is opened further, the right spring shoes 4a, 4b of the left sliding door 13a are moved past the left spring shoes 4a, 4b of the right sliding door 11b. As a result, the spring arms 7 of the left spring shoes 4a, 4b of the right sliding door 13b are deflected by the first longitudinal edge 6a of the base body 5 of the left sliding door 13a which has been pushed past, against its elastic recovery force - in each case to its final position (Fig. 3c).

The left sliding door 13a is further moved to the right and, in this connection, the left side of the left sliding door 13a is also pushed inwards (direction of the arrow) in order to also move the left door side transversely together with its runners. corresponding left spring bars 4a, 4b towards the plane behind the right sliding door 13b (Fig. 3d). Despite the fact that the base body 5 has been pushed forward, the spring arms 7 of the left spring shoes 4a, 4b of the right sliding door 13b remain in their final position because the longitudinal edges 9 of the spring arms 7 rest against the left sliding door 13a.

When the now rear sliding door 13a is opened further, the spring arms 7 of the right spring shoes 4a, 4b of the now front sliding door 13b are then also deflected by the first longitudinal edge 6a of the base body. 5 of the rear sliding door 13a, which has been pushed past its spring-return force in each case to its end position (FIG. 3e). Now all the spring arms 7 of the two sliding doors 13a, 13b are stressed so that on the one hand the front sliding door 13b continues to rest against the groove flank 3a and on the other hand the rear sliding door 3b rests parallel against the front sliding door 13b.
