Description

The present invention relates to a rail for sliding door fittings, in particular, a piece of furniture, or a household appliance, or a dividing wall, having at least two running tracks for rollers, which are displaced to each other in the vertical direction.

From DE 2553175, a sliding door fitting is known in which the rail is fixed to the top panel, with the running tracks located one above the other. The result is a particularly compact design in which the profile is formed integrally in the form of a pressed profile. Such extruded profiles have high strength, but material consumption is high due to thick walls. This makes the production of extruded rail profiles expensive.

Therefore, the present invention is directed to the creation of a rail for sliding door fittings, which can be manufactured simply and at the lowest cost.

This problem is solved in the rail for the sliding door reinforcement, having the characteristics of paragraph 1 of the claims.

In accordance with the invention, the rail is made whole from a bent plate, which reduces the use of material in comparison with extruded profiles. Thus, the rail can be manufactured efficiently and at the lowest cost, and it is also possible to manufacture fewer parts.

In accordance with one preferred embodiment of the invention, the bent plate has a thickness of from 0.4 mm to 3 mm, in particular from 0.5 mm to 1.5 mm. The rail, therefore, can be made taking into account the weight load, and the rails for small and lighter sliding panels can be made thinner than for heavy sliding doors.

The first and / or second running track is preferably made in a curved or V-shaped cross section. Thus, the running track can provide good stability when acting as a guide in which, due to the weight load, the rollers move on the rail in a self-centering manner.

According to one preferred embodiment, the rail, at least locally, has adjoining bent sections or almost adjoining bent sections if, after the bending procedure, the spring divergence of the plates from each other cannot be completely avoided. These (almost) adjoining sections increase the stability of the rail, while optionally, it is possible to additionally connect the (almost) adjoining sections by means of fastening, for example, joining inseparably by welding or gluing, or other fastening means, for example, rivets, screws or molding, for example riveting or chasing. Thanks to the (almost) contiguous sections, which are additionally bonded to each other, rails with particularly stable dimensions are obtained. In this case, the arrangement of the running tracks displaced in the vertical direction with respect to each other provides sufficient balancing, so that great efforts can be perceived with a small thickness of the steel plate. The manufacture of such rails, even if additional fastening of the sections based on each other is carried out, can be effectively carried out industrially and with high quality.

In one preferred embodiment of the invention, the rail has a horizontal shoulder, which can be fixed on the base or on the top panel of a piece of furniture. For this purpose, the rail can be screwed to the upper side or the end side of the upper panel. The rail may also have an upper vertical shoulder, which is adjacent to the upper horizontal shoulder, while a horizontally protruding section may be provided on the lower shoulder to form the first running track. To obtain a particularly compact structure on the rail, a second lower vertical shoulder is additionally provided, which is located at least partially below the upper vertical shoulder and has a horizontally protruding section on the lower side to form a second running track. In such an embodiment, the upper vertical arm and the lower vertical arm can be located in the same plane so that both arms are pressed at least partially against the end face of the upper panel or base, which increases stability. Also, it is possible to provide for the displacement of the upper vertical shoulder and the lower vertical shoulder to each other in different planes, so as to provide a more stepwise formation of the rail, which makes it possible to use the structural space above the lower vertical shoulder.

In accordance with the invention, it is preferable if a recess is provided in the rail into which the drive of the damping device or closure enters. A door closer or damping device can thus be hidden behind the rail, which improves the appearance.

The rail in accordance with the invention may be contained in the fittings of the sliding door, moreover, several of these rails can be fixed closely to each other by means of butt connectors. To this end, the rail may have one or more hollow chambers into which corresponding connecting elements are inserted.

The invention is further described in more detail based on several exemplary embodiments, with reference to the accompanying drawings, where:

- in FIG. 1 is a perspective view of a piece of furniture having a rail in accordance with the present invention;

The furniture item 1 comprises a furniture case 2, which has a top panel 3 on which the rail 4 is fixed. In addition, an additional rail can be fixed on the basis of the furniture item 1, so that the front sliding door 5 and the rear sliding door 6 are guided as rail 4 on the upper panel, and on the lower rail. The following describes only the rail 4 on the top panel 3, however, an identical rail can be installed on the basis of item 1 of cabinet furniture. Alternatively, only a sliding guide may be provided on the base.

In FIG. 2 shows the suspension of the front sliding door 5, which overlaps with the rear sliding door 6, at least in the open position, through the U-shaped holder 7. At least one roller that can be moved in the upper rail 4 is guided on the holder 7. In FIG. 2, in addition, a casing 11 of a door closer, or damper, preferably a damped door closer, having a drive 10, which engages with an activator 9 connected to the holder 7, is shown. By means of the damped door closer, the sliding doors 5 and 6 can be braked or held both in the direction opening and closing direction. The drive 10 in this case is guided through a recess in the wall of the rail 4.

In FIG. 3 shows the suspension of the rear sliding door 6. The holder 8 is mounted on the rear side of the rear sliding door 6, which engages through the activator 9 with the drive 10 of the closer or damper. The drive 10 is movably held in this case on the casing 11 of the closer or damper, and the drive 10 is also engaged through a recess in the rail 4. In this case, the rear sliding door 6 is movably held by means of at least one roller in the lower track 21 of the rail 4 .

In FIG. 4, the rail 4 is shown in side view and it can be seen that the front sliding door 5 is movably held by the roller 12 on the upper track 20, and the rear sliding door 6 is movably held by the roller 12 on the lower track 21. The rollers 12 have a bearing surface V -shaped, the tracks 20 and 21 are also made with a V-shaped cross section. Of course, other geometric shapes are possible, for example, curved supporting surfaces of a concave or convex shape, as well as supporting surfaces of an inverted V-shaped.

In FIG. 5 shows a cross section of rail 4. Rail 4 consists of a bent steel plate having a thickness between 0.4 mm and 3 mm, in particular between 0.5 mm and 1.5 mm. In this case, the rail 4 comprises an upper arm 22, which can be superimposed on the upper panel 3 or the base. The first vertical shoulder 23 is in contact with the horizontal shoulder 22, on the lower side of which the protruding horizontal section forms the upper running track 20. For this purpose, ribs 24 and 25 are provided with a V-shape, and an outer vertical edge 26 is formed on the outer rib 25, which prevents popping forward of the roller 12. The transition section 27 is in contact at the bottom with the edge 26, to two V-shaped ribs 28 and 29, which extend parallel to the ribs 24 and 25 on the lower side. In the region of the upper track 20, the steel plate of the rail 4 is doubled so that the upper track has increased stability. The (almost) contiguous sections of the rail 4 can also be further fixed to one another, for example, by welding, gluing, profiling or other means of increasing the stability of the rail 4.

The second vertical shoulder 30 is in contact with the rib 29, which has a horizontally protruding section on the lower side to form the lower track 21. The vertical shoulders 23 and 30 are in this case located in the same plane and can, at least partially, press on the end side of the upper panels 3. The lower running track 21 is also formed by two ribs 31 and 32 arranged in a V-shape, and an upwardly protruding edge 33 is formed on the outer rib 32 for guiding the roller 12 to prevent the roller 12 from popping out.

The following figures 6-12 show modified examples of embodiments of the rails in accordance with the invention, where the same rail sections 4 of FIG. 5 are denoted by the same reference numerals and only modifications are explained.

In FIG. 6 shows a rail 4 ', in which the upper horizontal arm 22' has a slightly raised middle section and two underlying extreme sections. The horizontal arm 22 'thus rests only on the extreme sections on the top panel 3.

In addition, in the rail 4 ′ of FIG. 6, the region below rib 25 is changed since in this region the rail 4 'is not formed with a double wall. Instead, the rib 28 'is located at a distance from the rib 25. In contrast, the rib 24 is supported by the lower rib 29 of the rail 4', so that there is some stabilization due to the presence of double walls in at least this area. In general, the track 20 has mechanical stability due to the vertical transition section 27 ′ formed on the horizontal rib 28 ′, with support on the rib 25. An alternative embodiment corresponds to FIG. 5.

In FIG. 7 shows a modified rail 4 ″ in which the longer horizontal arm 22 ″ rests on the upper panel 3. The arm 22 ″ is formed linearly in this case and passes, after bending, into the vertical arm 23. The rib 25 is also formed with only one the wall on the track 20 in this embodiment is not supported by the additional rail section 4 ″, since the rib 28 ″ is located at a distance from the rib 25. The vertical section 27 ″, which significantly increases the bending stiffness of the track 20, is between the rib 28 '' and vertical the flanged edge 26. On the contrary, the rib 24 is supported by the lower rib 29.

In FIG. 7, in addition, the region of the lower running track 21 is slightly changed, since the edge 33 does not end with a vertical section, but is bent along a fold 34, so that a vertical section 35 and a section 36 oriented outwardly diagonally are obtained. One edge of section 36 is thus sufficiently hidden. In the case of particularly high weight forces, the track 21 can be supported by a section 36 tilted slightly upward. You can also connect the rib 32 in a completely one-piece way, for example, by gluing or welding, with section 36.

On the rail of FIG. 8, the region below the upper track 20 has been changed. The vertical shoulder 50 is adjacent to the edge 26, which goes into a horizontal rib 51, before a vertical shoulder 30 is formed on the rail, on the lower side of which a lower track 21 is provided. Upper track 20 Thus, it is completely formed from one wall and is located at a distance from the horizontal rib 51.

In FIG. 9, the rail 4 is substantially modified in the region of the lower running track 21, since a fold 34 and a downwardly oriented vertical section 35 are provided near the vertical edge 33.

In FIG. 10, the rail 4 is also modified in the region of the lower track 21, since, with respect to FIG. 9, the V-shaped ribs 37 and 38 also abut and support the ribs 31 and 32. Both the upper running track 20 and the lower running track 21 are formed with double walls, so that the running tracks 20 and 21 are particularly stable.

In FIG. 11 shows a slight modification with respect to FIG. 10, in which only the lower running track 21 is formed with double walls on one side of the rib 37.

In FIG. 12 shows an additional embodiment of a rail in which the upper vertical arm 23 ′ is laterally offset to the lower vertical arm 30 ′. The upper track 20 'is formed on the upper vertical shoulder 23', which is already not V-shaped, but curved upward. For this, the upper track 20 'is supported on two vertical ribs 60 and 61. The horizontal rib 62 is adjacent to the rib 61, which presses on the curved section opposite the vertical rib 60, while the rib 60 and rib 62 can be fixed to each other in the contact zone to increase stability. The lower vertical shoulder 30 'is located in the plane of the vertical rib 60, to the lower side of which lies the lower running track 21', which is formed, like the upper running track 20 ', from a substantially square profile, the upper side of which is curved.

An arrangement is also possible in which the arms 23 'and 30' are arranged vertically in the same plane.

In FIG. 13 shows the rail of FIG. 12 with sliding door fittings, in which the roller 12 'is on the holder 7, and the lower roller 12' is on the holder 8. The rollers 12 'are guided along the upper track 20' and along the lower track 21 ', while the rollers 12' form a curved or V-shaped in cross section support and are guided along the tracks 20 'and 21' in a self-centering manner. To this end, the rollers 12 'have lateral edges 70, which have a larger diameter than the running gears 71 of the rollers.

In FIG. 14 and 15 show the joint of two rails 4 '' end-to-end, i.e. at the end. Rail 4 ″ is similar in cross section to the rail of FIG. 7, in which, to connect two rails 4 ″, the connecting elements 40 are inserted into the hollow chambers 41, which are formed by a curved contour of the rail 4 ″. The connecting elements 40 are triangular in cross section and can be inserted into the hollow chamber below the outer rib 25 of the upper track 20 and the lower rib 32 of the lower track 21. On the lower track 21, the end section 36 is slightly widened with respect to FIG. 7, which gives a closed cavity.

In FIG. 16 shows an embodiment along the cross-sectional profile corresponding to FIG. 5, in which the rail 4 is fixed on the upper panel 3. For a stronger fixation on the lower side of the upper panel 3, in particular, an angular reinforcing element 80 is fixed, and the reinforcing element 80 can also be fixed on the rail 4 on a vertical contact surface, for example, with glue, screws or other fasteners.

In FIG. 17 shows a rail, with two running tracks 20 and 21, which are located one above the other, each formed by edge sections of a bent steel plate, while the middle section is angled with respect to the upper side of the upper panel. The section resting on the upper panel is thus made as a double-walled section.

In FIG. 18 shows a cross section of a rail in which two running tracks 20 and 21 are located one above the other, with a vertical section 23 above the running track 20 and a vertical section 30 of the running track 21 located on opposite sides of the running tracks 20 and 21.
