Description

Technical Field

[0001] The present invention relates to a guide device for a sliding door system, the guide device comprising: a guide rail, at least three sliding doors being movably held on the guide rail via operating components, each sliding door being movable along a track on the guide rail via at least one operating component having a roller, and the guide rail having at least two parallel tracks; at least one positioning member in the form of a locking element or a self-closing device, which is arranged on the guide rail to position one of the sliding doors in a predetermined position along the guide rail, and the present invention relates to a furniture item. Background Art

[0002] DE 10 2018 112 021 A1 discloses a guide device for a sliding door, in which a mounting component is inserted into the front end of a guide rail. Multiple mounting elements are formed on the mounting component to secure stops or self-closing devices, thereby securing the operating components and, therefore, the sliding door, in a predetermined position. The arrangement of such a positioning component in the central area is complex, as the position of the central sliding door may vary depending on the design of the furniture. To install the central positioning component, the position must first be calculated according to the instructions, and then the positioning component must be accurately installed. This can lead to errors that affect the positioning of the sliding door in the open or closed position.

[0003] To assemble a retractable damper fitting, EP 3 358 115 B1 discloses the attachment of a door marker to the door leaf and the alignment of a profiled sheet on the door marker to specify the position of the door leaf. This assembly is also relatively complex. Summary of the Invention

[0004] It is therefore an object of the present invention to provide a guide device for a sliding door system which allows an effective alignment and mounting of a positioning member in the central region of a guide rail.

[0005] This object is achieved by a guide device having the features of claim 1 .

[0006] In the guide device according to the present invention, at least one positioning member in the form of a locking element or self-closing device is provided for positioning one of the sliding doors in a predetermined position along the guide rail. At least one marking is provided on the guide rail at a distance from the front end of the guide rail, and the at least one positioning member can be aligned with the marking via the marking and fixed to the guide rail. Thus, during assembly, the guide rail can be used to align the positioning member, which is directly or indirectly fixed to the guide rail. This reduces sensitivity to errors during assembly and results in more precise positioning of the sliding door by the at least one positioning member.

[0007] Preferably, a mounting element is fixed to the guide rail, the marking is arranged on the mounting element, and at least one of the positioning members is fixed to the mounting fixture. The mounting element can thus be aligned and fixed to the guide rail via the marking, so that one or more positioning members can be fixed to the mounting element. Preferably, two positioning members are fixed to opposite sides of the mounting element. The marking on the mounting element can be formed as a protrusion, a recess, an embossment, a color marking or other marking means to enable alignment of the mounting element relative to the marking on the guide rail.

[0008] The mounting element preferably comprises at least one web, in particular two aligned webs, on which a plurality of mounting points are formed for securing the positioning member. Each mounting point can be designed as a receptacle to which the positioning member can be secured via a clamping element. Other mechanical fixings of the positioning member at the mounting points are also possible, such as via pins, protrusions, locking elements, or clamping devices. Furthermore, the positioning member can be pre-secured to the mounting element by means of protrusions formed thereon, which precisely engage in recesses in the mounting element to facilitate handling. By securing the mounting element, simple assembly and alignment of the positioning member are achieved. The provision of multiple mounting points on the web enables the positioning member to be positioned differently on the mounting element and, therefore, the sliding door to be positioned differently depending on the furniture design. Thus, when using multiple mounting elements arranged in parallel planes, precise alignment of sliding doors with a predetermined grid size or movable parallel to one another can be achieved as required.

[0009] The mounting element is preferably symmetrical about a central plane, thereby avoiding errors due to improper positioning of the mounting element.

[0010] For compact design considerations, the guide rail preferably includes at least one groove adjacent to the track, into which the mounting element and / or the positioning member is inserted. This allows the force to be transferred from the activator connected to the sliding door to the positioning member on the guide rail. In this case, the positioning member can be designed as a simple locking element, to which the activator connected to the sliding door, such as a bar or a protrusion, is locked. Alternatively, the positioning member can also be designed as a self-closing device, in which the drive can be moved along the guide rail and preloaded in the closing direction by an accumulator, in particular a spring. The sliding door can then be moved to a predetermined closed or open position via the drive.

[0011] To facilitate installation, the marker on the guide rail can be centered in the longitudinal direction. The center position can be easily calculated and marked, allowing the mounting element to be secured in this center position, and the positioning member to be secured to the mounting element in the desired position. The marker on the guide rail can take the form of a protrusion, recess, embossing, color marking, or other marking means.

[0012] The guide device according to the present invention is preferably used for furniture articles, wherein the guide rail is fixed to the top panel of the furniture body. However, alternatively, the guide device can also be used for room dividers or other sliding door systems. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] A furniture item 1 includes a furniture body 2 and is designed as a cabinet-type furniture item. Guide rails 3 are fixed to the top panel of the furniture body 2 to hold sliding doors 5 and 7, allowing them to move. There are two rear sliding doors 5 that are movable along the guide rails 3 via running components 4, and a front sliding door 7 that is movable in front of the plane of the rear sliding doors 5 via running components 6.

[0024] Figure 2A and Figure 2B The figure shows a modified furniture item 1 ′, in which four sliding doors 5 and 7 are provided on the furniture body 2 ′ instead of three sliding doors 5 and 7, i.e., two rear sliding doors 5 and two front sliding doors 7 are provided. The rear sliding door 5 can be moved along a guide rail 3 ′ via a running member 4, and the front sliding door 7 can be moved along a guide rail 3 ′ via a running member 6, said guide rail being slightly longer than the guide rail in FIG. 1 .

[0025] In order to be able to position or stop the sliding doors 5 and 7 in certain positions along the guide rail 3, positioning members are provided. As disclosed in DE 10 2018 112 021 A1, these positioning members can be formed at the ends of the guide rail 3.

[0026] exist Figure 3A and Figure 3B , a guide rail 3 is shown in the central area, in which a positioning member 10 is fixed in the form of an automatic closing mechanism. Each positioning member 10 comprises a housing 11, on which a drive 12 is mounted so as to be able to move along a guide rail 13. The drive 12 is biased in the retraction direction via a spring and is preferably braked via a damper, so that the sliding door connected to the drive 12 can be braked in the retraction area and held and positioned in the final position. The housing 11 with the automatic closing member is not fixed to the guide rail 3 directly in this case, but via a mounting element 15. In addition, at least one pre-fixed protrusion 14 and at least one clamping element 21 (two clamping elements 21 as an example in this embodiment) are formed on the bottom side of the positioning member 10.

[0027] The mounting element 15 comprises two end webs forming mounting points 17, 18 and 19. Each of these mounting points 17, 18 and 19 serves as a receptacle for at least one clamping element 21 on the positioning member 10, which is formed as a slide, for example. The slide can thus be moved from the upper side of the positioning member 10 into a locking position with the aid of a tool, such as a spanner. In addition, a pre-fixed projection 14 designed as a web is arranged on at least one end face of the positioning member 10, which projection can be inserted in a force-fit and / or form-fit manner into one of a plurality of pre-fixed receptacles 22 formed on the mounting element 15. This enables the positioning member 10 to be pre-fixed to the mounting element 15, so that the entire component unit can ultimately be fixed to the guide rail 3 in an assembly-friendly manner. Here, as Figure 9 、 Figure 10 and Figure 11 As can be seen particularly well, the pre-attached receptacles 22 can be formed by two upwardly extending webs, which create a free space for receiving the pre-attached protrusions 14. After at least one positioning member 10 has been pre-attached to the mounting element 15, at least one slider arranged on the positioning member 10 can be used to secure the assembly unit comprising the at least one positioning member 10 and the mounting element 15 to the guide rail 3. In this embodiment, each positioning member 10 has two sliders, and both positioning members 10 are arranged on the mounting element 15. However, the number of these components can of course vary depending on the desired application. The fact that the pre-attached protrusions 14 can be inserted at various locations on the mounting element 15, and the clamping elements 21 can be fixed at the mounting points 17, 18, or 19, makes it possible to achieve desired spacing with a predetermined grid size when using multiple mounting elements 15 in parallel planes, and of course, to achieve precise flushness of the sliding doors 5 and 7, which can move parallel to each other.

[0028] exist Figure 3B In FIG, the mounting element 15 is shown with two positioning members 10 in the mounted position and it can be seen that these are essentially received in recesses on the guide rail 3 and that essentially only the driver 12 of the respective positioning member 10 protrudes upwards beyond the guide rail 3.

[0029] Figure 4 Two positioning members 10 are shown in an assembled position with mounting elements 15. The mounting element 15 comprises a centrally arranged upwardly projecting marker 16 in the form of a projection, with mounting elements 15 formed symmetrically on either side of the marker 16. On both sides of the mounting element 15, webs protrude, on which, as previously described, the respective positioning member 10 is pre-fixed in one of the pre-fixed receptacles 22 via insertion of the pre-fixed projection 14.

[0030] exist Figure 5 In the figure, the positioning member 10 is shown engaged with an activator 20 coupled to a driver 12, so that the driver 12 can move the activator 20 to a final position via a force accumulator. The activator 20 is coupled to the running part 6 that supports the front sliding door 7. The rear sliding door 5 can also be coupled to the driver 12 via a similar activator 20.

[0031] like Figure 6 As shown, a marker 32 is used to install and align the positioning member 10 in the central region of the guide rail 3. During assembly, for example, the marker 32 is arranged or drawn in the center in the longitudinal direction of the guide rail 3 so that the two lengths x and y are equal. Optionally, the marker 32 can also be provided at another position in the central region of the guide rail 3, depending on the design of the subsequent furniture.

[0032] The guide rail 3 comprises two rails 30 which are formed, for example, of webs with mushroom heads, but which may also have a different shape. Adjacent to each of the rails 30 is a groove 31 into which the positioning member 10 is later inserted.

[0033] After the marker 32 has been applied to the guide rail 3, as Figure 7 As shown, one or more mounting elements 15 are inserted or pushed into the guide rail 3. Here, a marker 16 in the form of a projection serves to align the mounting element 15 so that the mounting element 15 with the marker 16 is fixed centrally in the guide rail 3.

[0034] After one or more mounting elements 15 have been inserted into the guide rail 3, as shown Figure 8 As shown, the positioning member 10 can be fixed in place. Here too, the position of the positioning member 10 can vary, depending on how the furniture will look in the future, whereby the clamping element 21 designed as a slot block can be optionally accommodated in one of the mounting points 17, 18 or 19 according to the positioning member 10. The mounting points 17, 18, 19 are formed as receptacles to serve as clearances for the clamping element 21 after at least one pre-fixed protrusion 14 on the positioning member 10 has been inserted into the desired pre-fixed receptacle. In the embodiment shown, two mounting elements 15 are mounted on the guide rail 3, so that four positioning members 10 can be fixed to the guide rail 3. The number of positioning members 10 can of course vary, depending on the design of the guide rail 3 and the furniture.

[0035] Figure 9 A modified mounting element 15 is shown, in which the marker 16 ′ is formed in the form of a projection having a triangular shape, so that the vertices of the triangle can be aligned along the marker 32 on the guide rail.

[0036] exist Figure 10In the embodiment of the present invention, a modified marker 16 ″ is used with the mounting element 15 , which is a color marker or an imprint that aligns the mounting element 15 with the marker 32 .

[0037] Figure 11 A mounting element 15 is shown with a marker 16 formed as a protrusion with a square cross section.

[0038] The markers 16 , 16 ′ and 16 ″ can be provided during the manufacture of the mounting element 15 . The markers 32 , for example made of an extruded metal profile, can optionally be provided by the manufacturer of the guide rail 3 or by an assembler of the guide rail 3 .
