Description

Rail for a sliding door fitting

The present invention relates to a rail for a sliding door fitting, in particular a piece of furniture or household appliance or a partition, with at least two raceways for roles, which are arranged offset from one another in the vertical direction. DE 255 31 75 discloses a sliding door fitting in which a rail is fixed to an upper floor, in which the raceways are arranged one above the other. This results in a particularly compact design, wherein the profile is integrally formed as an extrusion profile. Although such extrusion profiles have a high stability, but also the material consumption by the thick wall thicknesses is large. This makes the production of the extruded rail profiles expensive.

It is therefore an object of the present invention to provide a rail for a sliding door fitting, which is simple and inexpensive to produce.

This object is achieved with a rail for a sliding door fitting with the features of claim 1.

According to the invention, the rail is produced in one piece from a bent sheet metal, so that the use of material is reduced compared with extruded extruded profiles. As a result, the rail can be produced effectively and inexpensively, whereby a production of smaller quantities is possible. According to a preferred embodiment of the invention, the bent sheet has a thickness between 0.4 mm and 3 mm, in particular 0.5 mm and 1, 5 mm. As a result, depending on the weight load, the rail can be produced, with rails for smaller and lighter sliding sash can be made thinner than for heavier sliding doors.

Preferably, the first and / or second track is curved in cross-section or V-shaped. This allows the track to provide good lateral stability in the track, with the wheels traversed by the weight load on the track in a self-centered manner. According to a preferred embodiment, the rail has at least partially touching bent portions or nearly touching bent portions, if a cracking of the sheets after the bending process can not be completely prevented. These (almost) touching portions increase the stability of the rail, optionally it is possible to connect the (almost) contacting portions additionally by fastening means, for example, materially by welding or gluing or by other fastening means, for example by rivets, screws or by means of forming technology, for example by clinching or embossing. The (almost) touching sections, which are optionally additionally fixed to each other, result in particularly dimensionally stable rails. The arrangement of the raceways, offset from each other in the vertical direction, ensures favorable leverage, so that high forces can be absorbed with a small thickness of the steel sheet. The production of such rails, even with additional attachment of adjacent sections, can be effectively produced industrially with high quality. In a preferred embodiment of the invention, the rail has a horizontal leg which can be fixed on a floor or top floor of a cupboard furniture. For this purpose, the rail can be screwed to the top or a front side of the topsoil. The rail may then have an upper vertical leg, which adjoins the upper horizontal leg, wherein on the lower side a horizontally projecting portion is provided for forming a first raceway. For a particularly compact design, a second lower vertical leg is additionally provided on the rail, which is arranged at least partially below the upper vertical leg and on the underside has a horizontally protruding portion for forming a second raceway. In such an embodiment, the upper vertical leg and the lower vertical leg can be arranged in a plane, so that both legs abut at least partially on the front side of an upper floor or a floor, which increases the stability. It is also possible to provide the upper vertical leg and the lower vertical leg offset from each other in different planes, so that a more gradual formation of the rail is given, which allows the use of space above the lower vertical leg. In the rail according to the invention preferably a recess is provided, which is penetrated by a driver of a damping device or a self-closing device. As a result, the self-closing device or the damping device can be arranged concealed behind the rail, which improves the appearance.

A sliding door fitting may have a rail according to the invention, it being possible to fix a plurality of such rails to each other via butt joints. For this purpose, the rail may have one or more hollow chambers, in which corresponding connecting elements are inserted.

The invention will be explained in more detail with reference to several embodiments with reference to the accompanying drawings. Show it:

Figures 16 to 18 further embodiments of a rail of a sliding door fitting. A cabinet 1 comprises a furniture body 2, which has a top 3, to which a rail 4 is fixed. Furthermore, a further rail can be fastened to the cabinet unit 1 on a floor, so that a front sliding door 5 and a rear sliding door 6 are guided both on the rail 4 on the upper floor and on the lower rail. Hereinafter, only the rail 4 is explained in more detail on the upper floor 3, wherein it is possible to fix a same rail at the bottom of the cabinet furniture 1. Instead, only a sliding guide can be provided on the ground. In Figure 2, the suspension of the front sliding door 5 is shown, which engages over a U-shaped holder 7, the rear sliding door 6, at least in an open position. On the holder 7, at least one roller is guided, which is movable in an upper guide rail of the rail 4. In Figure 2, a housing 1 1 of a Selbsteinzuges or a damper is also shown, preferably a damped self-feeder having a driver 10 which is in engagement with an activator 9, which is connected to the holder 7. The sliding doors 5 and 6 can be braked or held both in the opening direction and in the closing direction via damped self-closing. The driver 10 is performed by a recess in a wall of the rail 4.

In Figure 3, the suspension of the rear slider door 6 is shown. On the rear sliding door 6, a holder 8 is fixed on the rear, which is an activator 9 in engagement with a driver 10 of a self-closing or a damper. The driver 10 is held movably on a housing 1 1 of the self-closing or the damper, wherein the driver 10 passes through a recess in the rail 4. The rear sliding door 6 is held by at least one roller in a lower track 21 of the rail 4 movable. In Figure 4, the rail 4 is shown in a side view, and it can be seen that the front sliding door 5 is held by a roller 12 on an upper track 20 and the rear sliding door 6 via a roller 12 on a lower track 21 movable. The rollers 12 have a V-shaped bearing surface, and also the raceways 20 and 21 are formed in cross-section V-shaped. Of course, other geometries are also conceivable, for example, curved bearing surfaces in concave or convex shape and vice versa V-shaped bearing surfaces. In Figure 5, the rail 4 is shown in a cross-sectional view. The rail 4 consists of a bent steel sheet having a thickness between 0.4 mm and 3 mm, in particular 0.5 mm and 1, 5 mm. In this case, the rail 4 comprises an upper leg 22 which can be placed on the upper floor 3 or a floor. The horizontal leg 22 is adjoined by a first vertical leg 23, on the underside of which a protruding, horizontally lying section forms the upper raceway 20. For this purpose, two V-shaped webs 24 and 25 are provided, wherein on the outer web 25, an outer vertical edge 26 is formed, which prevents jumping out of the roller 12 to the front. At the edge 26, a transition section 27 shoots down before two V-shaped webs 28 and 29 are provided, which extend parallel to the webs 24 and 25 at the bottom. In the region of the upper track 20, the steel sheet of the rail 4 is doubled, so that the upper track 20 has an increased stability. The (almost) touching portions of the rail 4 may additionally be fixed to each other, for example, by welding, gluing, profiling or other measures to increase the stability of the rail 4.

The web 29 is adjoined by a second vertical leg 30, which has a horizontally protruding section on the lower side for forming the lower raceway 21. The vertical legs 23 and 30 are arranged in a plane and can rest at least partially on the front side of the topsoil 3. The lower raceway 21 is also formed by two V-shaped webs 31 and 32, wherein on the outer web 32 an upwardly projecting edge 33 is formed for guiding the roller 12 to prevent jumping out of the roller 12.

In the following figures 6 to 12 modified embodiments of rails according to the invention are shown, wherein the same portions of the rail 4 in Figure 5 are denoted by the same reference numerals and only the modifications will be explained.

FIG. 6 shows a rail 4 'in which an upper horizontal limb 22' has a slightly raised middle section and two lower edge sections. As a result, the horizontal leg 22 'rests only on the edge portions on the upper floor 3.

Furthermore, in the rail 4 'in FIG. 6, the area below the web 25 is changed, since the rail 4' is not double-walled in this area is, but a web 28 'spaced from the web 25 is arranged. The web 24, however, is supported by the lower web 29 of the rail 4 ', so that a certain stabilization is provided by a double-walled construction at least in this area. The raceway 20 is mechanically stabilized in total by the integrally formed on the horizontal web 28 'vertical transition section 27' by this is supported on the web 25. Incidentally, the embodiment corresponds to FIG. 5.

FIG. 7 shows a modified rail 4 "in which a longer horizontal leg 22" rests on the upper floor 3. The leg 22 "is straight in this case and, after bending, merges into the vertical leg 23. Also in this embodiment, the web 25 on the raceway 20 is formed only single-walled and not supported by a further portion of the rail 4", since the web 28 "spaced apart from the web 25. Between the web 28" and the vertical edge 26 there is provided a vertical section 27 "which significantly increases the flexural rigidity of the track 20. The web 24, on the other hand, is supported by the lower web 29 ,

In FIG. 7, furthermore, the region of the lower raceway 21 is slightly modified, since the edge 33 does not end with the vertical portion, but is bent over by a fold 34, so that a vertical portion 35 and an obliquely upwardly directed portion 36 are provided are. As a result, an edge of the section 36 is arranged rather concealed. For particularly high weight forces, the raceway 21 can be supported by the slightly obliquely upwardly facing portion 36. It is also possible to materially connect the web 32, for example by gluing or welding, to the section 36.

In FIG. 8, the region below the upper raceway 20 has been modified in the illustrated rail. The edge 26 is followed by a vertical leg 50, which merges into a horizontal web 51 before a vertical leg 30 is formed on the rail, on the underside of the lower raceway 21 is provided. The upper raceway 20 is therefore formed completely single-walled and spaced from the horizontal web 51 posi- tioned.

In Figure 9, the rail 4 is modified substantially in the region of the lower raceway 21, since in addition to the vertical edge 33 is still a fold 34 and a downwardly directed vertical portion 35 are provided. In Figure 10, the rail 4 is also modified in the region of the lower raceway 21, as compared to Figure 9 is followed by two V-shaped webs 37 and 38 which support the webs 31 and 32. Both the upper track 20 and the lower track 21 are double-walled, so that the raceways 20 and 21 are particularly stable.

In FIG. 11, a slight modification is shown with respect to FIG. 10, in which the lower raceway 21 is designed to be double-walled only on one side by the web 37.

FIG. 12 shows a further embodiment of a rail in which an upper vertical leg 23 'is arranged laterally offset from a lower vertical leg 30'. On the upper vertical leg 23 ', an upper raceway 20' is formed, which is no longer V-shaped, but curved upward. For this purpose, the upper raceway 20 'on two vertical webs 60 and 61 is supported. The web 61 is adjoined by a horizontal web 62, which abuts a curved section on the vertical web 60, wherein the webs 60 and the web 62 can be fixed to one another in the contact region in order to increase the stability. In the plane of the vertical web 60, the lower vertical leg 30 'is arranged, on the underside of which a lower raceway 21' adjoins, which, like the upper raceway 20 ', is formed from a substantially square profile whose upper side is curved.

Also conceivable is an arrangement in which the legs 23 'and 30' are arranged vertkal in a plane.

In Figure 13, the rail shown in Figure 12 is shown with a sliding door fitting, wherein on a holder 7, a roller 12 'and a holder 8, a lower roller 12' are provided. The rollers 12 'are guided on the upper track 20' and the lower track 21 ', wherein the rollers 12' in cross-section form an arcuate or V-shaped support and are self-centering on the raceways 20 'and 21' out. For this purpose, the rollers 12 'have side edges 70 with a larger diameter than the raceways 71.

The connection of two rails 4 "on the impact side, that is to say on the front side, is shown in Figures 14 and 15. The rail 4" is similar in cross section to the rail of Figure 7, wherein connecting elements 40 are inserted into hollow chambers 41 for connecting two rails 4, due to the curved contour of the The connecting elements 40 are triangular in cross-section and can be inserted into the hollow chamber below the outer web 25 of the upper track 20 and of the lower web 32 of the lower track 21. At the lower track 21 the end-side section 36 is opposite 7 slightly elongated, so that there is a closed cavity.

FIG. 16 shows an embodiment which corresponds in cross-sectional contour to FIG. 5, in which a rail 4 is fixed to a top floor 3. For more stable fixing an angular reinforcing element 80 is fixed to the underside of the topsoil 3, in particular screwed, and the reinforcing element 80 may also be fixed to the rail 4 on a vertical contact surface, for example by gluing, screws or other fastening means.

In Fig. 17, there is shown a rail in which two superposed raceways 20 and 21 are provided, each formed by edge portions of the bent steel sheet, while a center portion is angularly guided to the upper surface of the upper floor. As a result, the resting on the top floor section is double-walled.

FIG. 18 shows a cross-sectioned rail in which two raceways 20 and 21 are arranged one above the other, the vertical section 23 above the raceway 20 and the vertical section 30 of the raceway 21 being arranged on opposite sides of the raceways 20 and 21 ,
