Light sliding element

The invention relates to a light sliding element, in particular for furniture, with a sliding element consisting of a frame and at least one plate, with at least two light elements with different colors and with a control box, wherein the sliding element is arranged in a sliding-guided manner by means of bearing elements on at least one stationary guide rail in and/or on a piece of furniture of any length.

Sliding elements are generally known in the furniture sector as functional elements, such as doors that allow access to a cupboard or compartment and are intended to keep it closed. It is also known that when doors or flaps are opened, a light element within the previously closed space is automatically switched on or can be switched on manually. This light element is primarily used to illuminate the space or compartment for access.

Furthermore, transparent display cases are known which have corresponding lighting elements within their enclosed space.

DE 201 05 323 discloses a piece of furniture, preferably in the form of a cube, in which at least one light source is installed. This light source can, since it consists of light sources of different colors, be changed in its color tone by mixing the different colored light sources by controlling the individual light sources in such a way that they emit different light, whereby the user

can choose the color of his furniture individually. The disadvantage here is that the walls of this furniture must be transparent in order to achieve the desired effect. The furniture is firmly assembled and cannot be moved or moved.

DE 198 31 765 A1 discloses an automatic door or window system which has a drive motor and other electrical devices which are supplied with power by means of various busbar and current collector systems. This door version is intended for use in buildings and includes extensive and expensive designs which are uneconomical in the low-price range of furniture.

The object of the invention is to create a light sliding element which has both the function of a sliding door and the function of a design element with variable coloring by means of lighting, whereby the above-mentioned disadvantages no longer occur and enables a particularly advantageous use on numerous different types of furniture.

This object is achieved according to the invention in that the control box and the lighting elements are arranged on the sliding element and illuminate the sliding element in every position assumed by it.

Advantageous developments of the invention are contained in the subclaims.

In a preferred embodiment, the light sliding element according to the invention consists of a sliding element that comprises a frame and a plate held by the frame, which plate consists of wood or glass, for example. Of course, a one-piece design of a plate is also possible.

The sliding element is supported on guide rails at the top and bottom by means of bearing elements, which are designed as rollers in the usual way. The guide rails are fixed in place in a piece of furniture on which this sliding element is placed. It can be moved both horizontally and vertically.

A control box is attached to the frame of the sliding element, which in one version also contains the lighting elements. Of course, the lighting elements can also be arranged elsewhere on the frame or on the entire frame. The lighting elements comprise at least two light-emitting diodes, for example of different colors. It is also possible to provide the light sources in the control box, for example, and to use light guides to guide the light to certain places on the frame of the sliding element or to other optical light-influencing devices such as scattering prisms.

Due to the mobility of the sliding element, it is necessary to supply the lighting elements on the sliding part with electrical energy via busbars and current collectors. It is advantageous for the lighting elements to be connected to an electrical storage element, which prevents the lighting elements from flickering when the sliding element is pushed back and forth. It is also advantageous to provide not just one pair but several pairs of current collectors, as this also advantageously prevents contact problems and thus flickering of the lighting elements when pushed.

The electrical storage element, which in this case forms a so-called buffer, is, for example, an accumulator, a battery or a storage capacitor.

In a further embodiment, the lighting elements are provided with an electrically conductive layer: for example,

an accumulator. The accumulator can be charged via busbars and current collectors, via an induction loop or a trailing cable.

The guide rails, which are fixed to the furniture, have a raised bar, the dimensions and profile of which correspond to the rollers of the sliding element. It is advantageous if the busbars are also arranged on the guide rail. It is particularly advantageous to arrange the busbars on both sides of the bar. The bar provides additional protection to increase the creepage and clearance distances between the busbars. In addition, if the current collectors are defective and parts of the current collectors have come loose, it can prevent these parts from causing a short circuit between the busbars.

In another embodiment, the guide rail has a web which is intended as a carrier for a busbar or which itself forms a busbar. Several such webs are also possible on a guide rail. In this case, the roller itself can form a current collector, or the current collectors are arranged separately from the roller.

It is advantageous if the current collectors are arranged on brackets of bearing arms attached to the frame of the sliding element. In a further embodiment, these bearing arms have brackets for simultaneously holding rollers with support means. Current collectors can thus be arranged on four rollers of the sliding element, which thus reduces contact disturbances in a simple manner.

Furthermore, it is advantageous to arrange the current collectors on the control box, as this eliminates the need for additional installation of electrical cables from the current collectors to the control box.

In a further development, the current collectors are assigned brushes or similar, which on the one hand clean the busbars and on the other hand protect them from contamination.

Another embodiment provides that the power supply for the lighting elements and/or the control box is via a trailing cable. This is particularly advantageous for short displacement distances.

It is also conceivable that the overall supply of the control box and lighting elements is provided by an electrical storage unit located in the control box, which is charged via busbars and current collectors, one or more induction loops or trailing cables.

In another embodiment, additional switching means such as mechanically and/or contactless actuated limit switches are arranged either in the guide rails or on the frame, whereby these switching means form switching and/or control functions for the lighting elements. For example, a certain color tone can be assigned to a certain position or area, which can be called up again and again.

The preferred design uses multi-colored LED arrays as lighting elements, which can be used to create numerous color combinations that can be set by operating controls on the sliding element, on the control box and/or using a remote control. The control box has corresponding receivers for the operating signals and control means for the lighting elements. A so-called dimming function for brightness control is also provided.

The supply voltage is a low voltage and is preferably 24 volts, so that protective measures for mains voltage operation of the busbars are not necessary.

It is also possible to design the bearing elements as plain bearings instead of rollers.

This creates a sliding light element for furniture that can be advantageously attached to many different pieces of furniture, largely independent of the shape of the furniture, and at the same time enables the function of closing and opening compartments as well as individually adjustable light and color design.

The invention is explained in more detail using exemplary embodiments in the drawing. It shows:

Fig. 2 shows a bearing of the sliding element according to Figure 1;

Fig. 3 Current collector of the sliding element according to Figure 1;

Fig. 4 a combined bearing/current collector element;

Fig. 5 is a partial view of a central steering section through the sliding element according to Figure 1;

Fig. 6 another example of bearings and pantographs; and

Fig. 7 another example of bearings and pantographs.

Figure 1 shows a possible embodiment of a sliding element 1 in perspective view. The sliding element 1 is in a preferred embodiment a sliding door or a movable panel of a piece of furniture. It consists of a frame 2 that supports and encloses a panel 3. The panel 3 can be designed as a transparent glass panel. Other designs, such as a wooden panel, are of course conceivable.

The sliding element 1 is attached to a piece of furniture (not shown here) in a sliding manner by means of bearing elements 7. The bearing elements 7 are preferably rollers which are arranged to rotate on support means 17 in a known manner.

Furthermore, the sliding element 1 has a control box 9 which is attached to the frame 2. The attachment point of the control box 9 is preferably in the upper area of the frame 2. It can also be completely integrated into the frame 2. The control box 9 contains a control box 9 which is shown in the figure.

at least one power supply, lamps and suitable control components for the lamps.

Figure 2 shows the mounting of the frame 2 of the sliding element 1 on a piece of furniture (not shown). The mounting is carried out by means of a guide rail 12 which is attached to the furniture part. The guide rail 12 has a web 13 on which the bearing element 7, here preferably a roller, is mounted in a sliding-guided manner.

It is also conceivable that the bearing element 7 and the web 13 can be a sliding bearing, in which the bearing element 7 is rigidly attached to the support means on the frame 2. The materials of the web 13 and the bearing element 7 are designed as a sliding bearing in this case.

The power supply in the control box 9 is fed by current collectors 10 that can be moved on current rails. The current collectors 10 are located on brackets that are attached to the frame 2 of the sliding element 1 by a bearing arm 8, as shown in the perspective view in Figure 3. The current rails that carry the current that is led into the control box 9 through the current collectors 10 with suitable conductor and insulation means are preferably arranged on the guide rail 12, as shown in Figure 4.

The current collectors 10 can be arranged individually, together on the support arm 8, or in combination with the bearing element 7 on the frame 2 of the sliding element 1. Figure 4 shows such a combination. The support arm 8 has two brackets 11, which on the one hand serve to accommodate the current collectors 10 and on the other hand support or mount the support means 17. In this embodiment, it is particularly advantageous that the support means 17 is additionally reinforced by the bearing arm 8, thus enabling advantageous stability.

In a further embodiment, the bearing elements 7 are on the upper part:"unH!"am ^# unteireri part .'de^s· ftöhmehs ·2 · a'ijf guide rails

12, whereby the guide rails 12 have conductor rails 14 arranged both at the top and at the bottom of the furniture. With a design of two current collectors 10 per bearing element 7, as shown in Figure 4, an advantageous current transfer from the conductor rails 14 to the current collectors 10 is possible. This is particularly advantageous so that a particularly good current transfer between the conductor rails 10 and the current collectors 14 is achieved when the sliding element 1 is moved.

In the embodiments shown here in Figures 2 to 4, the busbars 14 are arranged on both sides of the web 13 on the guide rail 12. This is particularly advantageous because the arrangement of the web 13 between the busbars 14 separates and insulates the two busbars. This reduces the likelihood of possible short circuits caused by defective current collectors 10, the parts of which are prevented by the web 13 from causing an electrical bridge as a short circuit between the busbars 14.

Other shapes of the guide rail 12 and the arrangement of the web and the busbars 14 are conceivable. It is also possible to arrange only one busbar 14 or more than two busbars 14 on one guide rail.

Figure 5 shows a further embodiment in which the current collectors 10 are arranged directly on the control box 9. This is particularly advantageous because it eliminates the need to install electrical cables from the current collectors 10 along the frame 2 of the sliding element 1 to the control box.

The control box is attached to the upper part of the frame 2 as shown in Figure 5. In this embodiment, the frame 2 contains a plate 3 made of glass. A light element 6 is arranged between the control box 9 and the plate 3. The light element 6 can be a light-conducting material

light-conducting properties that transmit the light to the plate 3. In the glass version, the plate 3 also transmits the light or scatters it, thereby achieving certain lighting effects. The lighting element 6 can also be designed directly as an active lighting element, for example as a light-emitting diode array. It is also possible that in the case of a non-transparent plate 3, this is illuminated from the outside, with the lighting means being arranged on the outside and being supplied by the control box, for example via light guides or electrical connections.

Figure 6 shows a further embodiment of the arrangement of the bearing elements 7 and the busbars 14. Here, the busbars 14 are arranged on a lower furniture part 5 and designed such that the bearing elements 7 are arranged on them in the form of rollers. The rollers are electrically insulated from one another, which is easily possible using a plastic axle 16, for example, and at the same time have the function of current collectors. In this embodiment, the frame 2 of the sliding element 1 hangs on the bearing elements 7 in the upper area on an upper furniture part 4 within a guide rail which is designed as a profile 15. The lower part of the frame 2 of the sliding element 1 is guided by the bearing elements 7 so that it rests against the busbars, whereby no or only small bearing forces of the sliding element 1 are transmitted in this area. The dead weight of the sliding element 1 generates a torque around the upper suspension of the bearing elements 7 in the profile 15, by means of which a certain contact pressure force is caused in the lower bearing elements 7 on the busbars 14.

Figure 7 shows a variant of the embodiment according to Figure 6 in the lower area as a partial view. Here, the sliding element with the lower bearing elements 7 stands on the busbars 14. The contact pressure of the bearing elements 7 on the busbars 14 is greater in this case.

&ngr; "V: :

In this embodiment, the busbars 14 are also designed as guide rails for larger support forces.

In a further embodiment, the guide rail 12 has two webs 13, which is not shown, wherein the webs 13 are designed as busbars. The power transmission then takes place in a known manner either directly via the bearing elements 7, which are designed as twin rollers insulated from one another, or through additional current collectors.

Additional switching means, such as limit switches, cam switches and/or magnetically actuated switches, can be arranged within the guide rail, which can be used for additional control purposes of the lighting elements 6.

It is also conceivable that the power supply, which is located in the control box 9, consists of an accumulator which can be charged contactlessly via induction strips laid in the guide rails 12 or in the profile 15.

The control box 9 contains control elements (not shown) with which the light element(s) 6 can be switched on and off and with which color changes can be carried out.

These control means are influenced either via multiple arranged power rails 14, or by means of a remote control via an infrared or radio connection.

In another embodiment, instead of busbars 14 and current collectors 10, so-called trailing cables are arranged, which are installed and accommodated within the furniture and/or the frame 2 of the sliding element 1.

It is also advantageous to protect the current collectors from contamination by suitable means such as brushes. These brushes clean the current rails 14 in a known manner when the sliding element 1 is moved.
