Description

The present invention relates to a guide device for a sliding door system with a guide rail on which at least three sliding doors are held so that they can be moved via running parts, each sliding door being able to be moved via at least one running part with rollers along a track on the guide rail and the guide rail having at least two parallel tracks, at least one positioning means in the form of a latching element or a self-closing mechanism being provided on the guide rail in order to position one of the sliding doors in a predetermined position along the guide rail, and a piece of furniture.

the DE 10 2018 112 021 A1 discloses a guide device for a sliding door, in which a mounting part is inserted on the front side of a guide rail, on which several mounting elements are designed for fixing a stop or a self-closing mechanism in order to hold a running part and thus a sliding door in a predetermined position. The arrangement of such positioning means in a central area is complex, since the position of a central sliding door can vary depending on the design of the furniture. To mount a central positioning means, the position must first be calculated according to instructions and then the positioning means must be mounted exactly. Errors can occur in this regard, which affects the position of the sliding door in an open or closed position.

For the assembly of a self-closing damper fitting, the EP 3 358 115 B1 attaching a door marker to a door leaf and aligning a profile sheet to the door marker to specify the position of the door leaf. This assembly is also comparatively complex.

It is therefore the object of the present invention to create a guide device for a sliding door system which enables effective alignment and assembly of a positioning means in a central region of the guide rail.

This object is achieved with a guide device having the features of claim 1.

In the guide device according to the invention, at least one positioning means in the form of a latching element or a self-closing mechanism is provided in order to position one of the sliding doors in a predetermined position along the guide rail, with at least one marking being provided on the guide rail at a distance from the front ends of the guide rail and the at least a positioning means can be aligned via an identification on the marking and is fixed on the guide rail. As a result, the guide rail can be used during assembly to align the positioning means, which is fixed directly or indirectly to the guide rail. This reduces the susceptibility to errors during assembly and leads to a more precise positioning of the sliding doors by the at least one positioning means.

A mounting element is preferably fixed to the guide rail, on which the marking is arranged and on which at least one of the positioning means is fixed. The mounting element can thus be aligned via the marking and fixed to the guide rail, so that one or more positioning means can be fixed to the mounting element. Preferably two positioning means are fixed on opposite sides of the mounting element. The marking on the mounting element can be in the form of a projection, recess, embossing, color marking or other marking means in order to be able to align the mounting element relative to a marking on the guide rail.

The mounting element preferably comprises at least one web, in particular two aligned webs, on which a plurality of mounting points for fixing a positioning means are formed. Each assembly point can be designed as a receptacle on which a positioning means can be fixed via a clamping element. A different mechanical fixing of the positioning means at a mounting point is also possible, for example using pins, projections, latching elements or clamping devices. In addition, the positioning means can be pre-fixed to the mounting element by a projection formed thereon, which engages in a recess of the mounting element in a form-fitting manner, in order to facilitate handling. By fixing the mounting element, the positioning means can be easily mounted and aligned, with the provision of several mounting points on the web enabling different positioning of the positioning means on the mounting element and thus of the sliding doors, depending on the structure of the furniture. Thus, when using several assembly elements in planes parallel to one another, a spacing with a predetermined grid dimension or an exact flushness of sliding doors that can be moved parallel to one another can be produced, as desired.

The mounting element is preferably designed symmetrically to a central plane, so that errors caused by incorrect positioning of the mounting element are avoided.

For a compact construction, the guide rail preferably comprises at least one groove adjacent to a track into which the mounting element and/or the positioning means is inserted. As a result, the force can be transmitted from an activator coupled to a sliding door into the positioning means on the guide rail. The positioning means can be designed as a simple latching element on which an activator, for example a web or a projection, which is connected to the sliding door, is latched. Alternatively, the positioning means can also be embodied as a self-closing mechanism, in which a driver can be moved along a guideway and is prestressed in a direction of retraction by an energy accumulator, in particular a spring. The sliding door can then be moved into a predetermined closed or open position via the driver.

For easy assembly, the marking on the guide rail can be arranged in the middle in the longitudinal direction. The middle position can be easily calculated and marked, so that the mounting element can be fixed in this middle position, on which the positioning means are then fixed in the desired position. The marking on the guide rail can be in the form of a projection, recess, embossing, color marking or other identification means.

The guide device according to the invention is preferably used in a piece of furniture in which the guide rail is fixed to a top panel of the furniture body. Alternatively, the guide device can also be used for room dividers or other sliding door systems.

A piece of furniture 1 comprises a furniture body 2 and is designed as a cabinet. A guide rail 3 is fixed to a top panel of the furniture carcass 2 in order to keep sliding doors 5 and 7 movable. Two rear sliding doors 5 are provided, which can be moved along the guide rail 3 via running parts 4, and a front sliding door 7, which can be moved via running parts 6 in front of the plane of the rear sliding doors 5.

In the Figures 2A and 2 B a modified piece of furniture 1' is shown in which four sliding doors 5 and 7 are provided on a piece of furniture 2' instead of three sliding doors 5 and 7, with two rear sliding doors 5 and two front sliding doors 7 being provided. The rear sliding doors 5 are running parts 4 and the front sliding doors 7 can be moved via running parts 6 along the guide rail 3', which is slightly longer than in FIG figure 1 .

In order to be able to position or stop the sliding doors 5 and 7 in certain positions along the guide rail 3, positioning means are provided. These positioning means can be formed at the ends of the guide rail 3 as shown in FIG DE 10 2018 112 021 A1 is revealed.

In the Figures 3A and 3B the guide rail 3 is shown in a central area in which positioning means 10 are fixed in the form of a self-closing mechanism. Each positioning means 10 comprises a housing 11 on which a driver 12 is mounted so that it can move along a guide track 13 . The driver 12 is prestressed in a retraction direction by a spring and preferably braked by a damper, so that a sliding door coupled to the driver 12 can be braked in a retraction area and held and positioned in the end position. A housing 11 of the self-closing mechanism is not fixed directly to the guide rail 3, but via a mounting element 15. Furthermore, at least one pre-fixing projection 14 and at least one clamping element 21, in this exemplary embodiment two clamping elements 21, are formed on the underside of the positioning means 10.

The mounting element 15 comprises two webs at the end, on which mounting points 17, 18 and 19 are formed. Each of these assembly points 17, 18 and 19 serves as a receptacle for the at least one clamping element 21 on the positioning means 10, which is designed, for example, as a sliding block. The slot nut can be moved into the locked position from the top of the positioning means 10 by a tool, for example a wrench. Furthermore, a pre-fixing projection 14 embodied as a web is arranged on at least one end face of the positioning means 10 and can be inserted with a force fit and/or form-fit into one of several pre-fixing receptacles 22 embodied on the mounting element 15 . This enables the positioning means 10 to be pre-fixed to the mounting element 15 in order to ultimately be able to fix the complete structural unit to the guide rail 3 in an easy-to-mount manner. Here, the pre-fixation recording 22, like the Figures 9, 10 and 11 show particularly well, be formed by two webs extending upwards, which create a free space for receiving the pre-fixing projection 14 . After that at least If a positioning means 10 is pre-fixed to the mounting element 15, the structural unit consisting of the at least one positioning element 10 and mounting element 15 can be fastened to the guide rail 3 by the at least one sliding block arranged on the positioning means 10. In this exemplary embodiment, the positioning means 10 has two sliding blocks and two positioning means 10 are arranged on the mounting element 15 . Of course, the number of these components can be varied depending on the desired application. Because the pre-fixing projection 14 can be inserted at various positions on the mounting element 15 and the clamping element 21 can be fixed at the mounting point 17, 18 or 19, when using a plurality of mounting elements 15 in planes parallel to one another, a spacing with a predetermined grid dimension is possible as desired, but of course also to realize an exact flushness of sliding doors 5 and 7 that can be moved parallel to one another.

In Figure 3B the mounting element 15 is shown with two positioning means 10 in the mounted position, and it can be seen that these are essentially accommodated in a groove on the guide rail 3 and essentially only the driver 12 of the respective positioning means 10 protrudes upwards over the guide rail 3 .

In figure 4 the two positioning means 10 are shown with the mounting element 15 in a mounted position. The mounting member 15 includes an upwardly protruding marker 16 in the form of a protrusion located centrally, with the mounting member 15 being formed symmetrically on either side of the marker 16 . On both sides of the assembly element 15 a web protrudes, on which, as described above, a positioning means 10 is pre-fixed by inserting the pre-fixing projection 14 into one of the pre-fixing receptacles 22 .

In figure 5 a positioning means 10 is shown in engagement with an activator 20, which is coupled to the driver 12, so that the driver 12 can move the activator 20 into the end position by the force accumulator. The activator 20 is connected to the running part 6 on which the front sliding door 7 is held. The rear sliding doors 5 can also be coupled to a driver 12 by similar activators 20 .

A marking 32 is used to mount and align the positioning means 10 in a central area of the guide rail 3, as shown in figure 6 is shown. During assembly, the marking 32 is applied or drawn in, for example, centrally in the longitudinal direction of the guide rail 3, so that the two lengths x and y are of equal length. Optionally, the marking 32 can also be provided at a different point in a central area of the guide rail 3, depending on the design of the subsequent piece of furniture.

The guide rail 3 comprises two tracks 30, which are formed, for example, by webs in the shape of mushroom heads, but can also have a different shape. A groove 31 is provided adjacent to the raceways 30 in each case, into which the positioning means 10 is later inserted.

After the marking 32 has been attached to the guide rail 3, one or more assembly elements 15 are introduced or pushed into the guide rail 3, as is shown in figure 7 is shown. The marking 16 in the form of the projection serves to align the mounting element 15 so that the mounting element 15 with the marking 16 is fixed centrally in the guide rail 3 .

After one or more assembly elements 15 have been introduced into the guide rail 3, the positioning means 10 can be fixed, as shown in figure 8 is shown. Here, too, the position of the positioning means 10 can be varied, depending on how the subsequent piece of furniture should look, with the clamping element 21 designed as a sliding block on the positioning means 10 being selectively receivable in one of the assembly points 17, 18 or 19. The assembly points 17, 18, 19 are designed as receptacles in order to serve as clearance for the clamping element 21 after at least one pre-fixing projection 14 on the positioning means 10 has been inserted into the desired pre-fixing receptacle. In the exemplary embodiment shown, two mounting elements 15 are mounted on the guide rail 3 so that four positioning means 10 can be fixed on the guide rail 3 . The number of positioning means 10 can of course be varied depending on the design of the guide rail 3 and the furniture.

In figure 9 A modified mounting member 15 is shown in which an indicia 16' is in the form of a protrusion which is triangular in shape so that the apex of the triangle can be aligned along the mark 32 on the guide rail.

In figure 10 a modified marking 16" is used in the mounting element 15, which is designed as a color marking or embossing in order to align the mounting element 15 with the marking 32.

figure 11 shows the mounting element 15 with the identification 16, which is designed as a square cross-section projection.

The markings 16, 16′ and 16″ can be provided during the production of the mounting element 15. The marking 32 can optionally be attached by the manufacturer of the guide rail 3 or by the fitter in the guide rail 3, which is made, for example, from an extruded metal profile.
