Description

The present invention relates to a guide rail fitting, in particular for a sliding door cabinet, with an upper guide rail and a lower guide rail, on which at least one sliding element is slidably mounted.

There are sliding door cabinets with a guide rail fitting, in which a plurality of sliding elements are guided one behind the other and can be moved to open the cabinet in a substantially overlapping position. In such sliding door cabinets, it is also known to provide just above the sliding door elements protruding bar with individual bulbs in the upper area. The usually punctiform radiating bulbs can illuminate in the area in front of the sliding door elements, but are relatively bright and can dazzle. In addition, too intense exposure to light is usually perceived as disturbing.

The document DE 203 03 045 U1 describes a unit formed from at least two sliding elements, which is equipped with an upper and a lower stationary guide rail for the sliding elements. On the upper guide rail is one or more holders for one or more lamps Illuminant or surrounding the light source cover made of a translucent material.

It is therefore an object of the present invention to provide an improved guide rail fitting with an upper and a lower guide rail with at least one light bar, which allows a compact design, a reduced number of components, reduced-power lighting with pleasant lighting and easy installation.

This object is achieved with a guide rail fitting with the features of claim 1.

According to the invention, a light strip is provided for illumination on at least one guide rail of the guide rail fitting. As a result, the guide rail fitting can be used both for guiding the sliding elements and for lighting.

Preferably, the light bar is arranged behind the sliding elements and radiates substantially indirect light over the floor or the ceiling in front of the sliding element. Such an indirect light is perceived by the viewer as pleasant because it is not dazzled and the lighting creates a certain room illumination. However, when a sliding door member is opened, the user can well perceive the interior because the illumination in the area of the guide rail fitting in the interior provides brighter light.

The light strip preferably extends over more than 70%, or more than 80% of the length of the guide rail, so that illumination is possible substantially over the entire width of the guide rail fitting.

The light bar can include an LED bar, so that with low power consumption and low heat generation a good illumination is obtained. In this case, the light bar may comprise a hollow profile in which the LED strip is arranged, for example by inserting. It is also possible to attach the LED strip outside only on a profile, the arrangement also provides protection against contamination in a hollow profile. The hollow profile can be formed from translucent plastic or glass.

For easy installation, the light bar can be locked to a guide rail or a holding profile. In this case, the light bar with respect to a plane which is spanned by a sliding element, radiate obliquely. The blasting to the front or to the rear has the advantage that the lighting can be targeted, used, for example, as an indirect lighting for a room or as lighting for the interior of a sliding door cabinet. By locking the light bar, the direction of the radiation of the light can also be adjusted during assembly.

For a simple construction, the light strip is closed at the side with a cap with an energy store. Alternatively, the light bar can also be connected laterally with a connection to a power supply, for example via a transformer.

The guide rail fitting preferably comprises both an upper guide rail and a lower guide rail, on each of which a light strip is provided. This ensures a particularly good room illumination inside or outside. In this case, two grooves for guiding two sliding elements and a groove for fixing a light bar can be provided on the lower guide rail. To guide a third sliding element can also be supplemented another groove.

A sliding door cabinet 1 comprises a furniture body 2, on which two sliding elements 3 and 4 are mounted displaceably on a front side. For this purpose, a lower guide rail 5 is provided, which is arranged at a distance from the bottom 6. At the top, an upper guide rail 7 is provided, on which the sliding elements 3 and 4 are mounted, wherein the front sliding element 4 is held on bracket 8 on the guide rail 7.

How out FIG. 2 can be seen, the sliding element 4 is mounted in the lower region via further bracket 22 so that the sliding elements 3 and 4 can be moved to a position one behind the other to open the sliding door cabinet 1. At the upper guide rail 7, a light bar 10 is provided on the side of a cap 9 is provided with an energy storage or a connection for connection to a power grid.

In FIG. 3 the upper portion of the guide rail fitting is shown in detail, wherein the guide rail 7 is fixed to a ceiling of the furniture body 2. The guide rail 7 has a substantially C-shaped cross section, wherein the bracket 8 are guided over rollers on the lower leg and the light bar 10 is mounted in the region of the upper leg. The light strip 10 may be latched, glued or mechanically fixed to the guide rail 7.

In FIG. 4 the light bar 10 is shown enlarged. The light strip 10 comprises a holding profile 11, which is fixed with a web portion 12 on the guide rail 7. The retaining profile 11 also has a groove with locking means 13 in the form of inwardly directed projections on which a hollow section 14 is fixed. The hollow profile 14 is formed of translucent plastic and engaged with a foot portion 15 in the groove of the retaining profile 11. In the hollow section 14, an LED strip 16 is inserted with bulbs. In this case, the LED strip 16 is arranged so that it radiates obliquely with respect to a plane which is spanned by the sliding elements 3 and 4, ie obliquely forward and downwards.

As in FIG. 5 is shown, the hollow profile 14 can be latched to the support section 11 in a modified position in which the hollow section 14 is rotated by 180 °, so that the LED bar 16 instead down now radiates upwards. In any case, the light strip 10 is arranged behind the sliding door elements 3 and 4, so that a person standing in front of the sliding door elements 3 and 4 can not be dazzled by direct light. Rather, the light strip 10 radiates light so that it only indirectly reaches the person via the ceiling. If the sliding door elements 3 or 4 are opened, however, the light strip 10 can provide for an illumination of the interior.

In FIG. 6 the lower portion of the guide rail fitting is shown in detail. The guide rail 5 comprises a first groove 27, in which a slider 23 is arranged for guiding the sliding element 4 via a bracket 22, and a second groove 28, are provided in the sliders 25 which hold the sliding element 3 via one or more brackets 24 , On the guide rail 5, a third groove is further provided, in which a light bar 20 is arranged. The light strip 20 comprises a hollow profile, which is formed as in the upper light strip 10. The light bar 20 again has an LED strip 21 which is arranged in the hollow profile and radiates obliquely down the front, the light is reflected by the bottom 6 to the front.

As in the FIGS. 7 to 9 can be seen, the guide rail 5 has a protruding ridge on which a plurality of openings are provided with screws 26 for fixing to the furniture body 2. The grooves 27 and 28 are open at the bottom and are used for lateral guidance of the sliding elements 3 and 4.

The foremost groove is latched to the light bar 20, wherein a foot portion 29 engages in the groove. Laterally, the light bar 20 is closed by a cap 30, which is connected to a power supply in the form of batteries or a connection for connection to a power grid.

In FIG. 10 the guide rail fitting is shown in the upper area, with only the arrangement of the light bar is changed. The guide rail fitting comprises the guide rail 7, on which rollers 41 are mounted on the lower leg, which hold the front sliding element 4 via a bracket 8. The lower sliding element 3 is also mounted on rollers 40 on the lower leg of the guide rail 7. Furthermore, a stopper 42 is provided, which limits the maximum sliding path of the sliding elements 3 and 4 relative to each other as a stop.

In this embodiment, a light bar 44 is not at the top of the guide rail 7 but below arranged on the guide rail 7. The light strip 44 is mounted on a holding profile 43 which is arranged in the region of the guide rail 7. On the retaining profile 43, a groove is formed, into which a foot 45 of a hollow profile engages, in which an LED strip 46 is arranged. The hollow profile may be formed as in the previous embodiment. The light bar 44 radiates obliquely downward light and can thus illuminate the interior of the sliding door cabinet well.

In the FIGS. 12 and 13 a modified embodiment of the guide rail fitting is shown in the upper region, in which on the guide rail 7, a light bar 50 is provided. The light bar 50 is substantially in cross section square or rectangular and comprises a hollow profile 55 which is glued to a bottom 51 on a groove 52 of the guide rail 7 or fixed by other fastening means. In the hollow profile 55 in a central region inwardly projecting strips 54 are formed, which hold an LED strip 53. As a result, the LED strip is arranged at a distance from the surrounding hollow profile 55, as in the preceding exemplary embodiments.

In the illustrated embodiments, the light bar extends over almost the entire width of the sliding elements 3 and 4, but at least over more than 70%. It is of course possible to form the light bar interrupted for each sliding element and set in individual sections on the guide rail 5 and 7 respectively. The light strips can be coupled to each other via connectors, so that they can be easily adapted to different widths of guide rails. The light strips can be fixed both mechanically by latching, or other mechanical fastening means to the support profiles or guide rails. In addition, it is also possible to make the light strip to be attached or glued. As a result, the light strips can be retrofitted to already mounted guide rail fittings in a simple manner.
