Description

The invention relates to a piece of furniture with a furniture body, wherein the furniture body has a rear wall, an attachable to the rear wall of the furniture body of the furniture support member and a movable furniture part, in particular a drawer, wherein a power consumer is arranged in or on the furniture part movable in the furniture.

Carrier elements for such furniture or furniture parts are already known, wherein the supply of electricity consumers with electricity as a major problem in the manufacture and use of such furniture occurs. From the EP 1 260 158 A2 For this purpose, a furniture drawer is already known, which has a arranged on the drawer, rechargeable power storage, which is chargeable via a arranged on the furniture body transfer device. A similar arrangement is also from the US 3,506,325 and from the US 5,276,310 known. However, a problem is the attachment of the power supply unit on the furniture body, which must be planned in the furniture body according to the arrangement of the drawers fixed. In addition, the power supply units sometimes have complicated cables arranged along or in the furniture carcass.

The present invention has therefore set itself the task of specifying a simpler and improved power supply for electricity consumers in drawers.

This object is achieved in that at least one power supply unit for the power consumer is detachably arranged on the carrier element. Although it is known to mount such a support element on the furniture body, but this support member is only for the holder of the ejector for the drawer (see WO 2006/017865 ). On such a carrier element, the power supply unit can be attached or snapped on, for example, via a clamping bracket.

According to a preferred embodiment it can be provided that in or on the carrier element, an electrical line is arranged, which communicates with an external power source and is connectable to the power supply unit. In such a carrier element, the electrical lines can run, wherein the power supply unit can also be contacted with such a line. This can be provided in such a way that when the power supply unit is attached to the carrier element, an electrical contact to the line takes place automatically, wherein according to a further exemplary embodiment the power supply unit can contact the electrical line with piercing pins. Alternatively, it is also possible that the electrical line is guided in or on the furniture body, wherein when attaching the power supply unit on the support element, the automatic contact between the power supply unit and arranged in or on the furniture body electrical line - for example via a plug - can be produced.

Preferably, it can be provided that the power consumer is a lighting device, wherein the lighting device preferably illuminates the interior of the drawer in its entirety. For example, the illumination device can be arranged on the rear wall of the drawer. Also, the power supply of displays or other power consumers to any area of the drawer can be done by the present invention.

To be able to guarantee the constant power supply, it can preferably be provided that a rechargeable power store is arranged in or on the movable furniture part, wherein in the closed position of the movable furniture part, the power supply unit charges the power storage via contact points. It is advantageous if the power supply unit charges the power storage only in the closed position and the electrical connection between the power supply unit and power storage when opening the movable furniture part is disconnected. Preferably, the power storage is connected to the power consumer and supplies it in the open position of the movable furniture part with electricity.

As already indicated, a preferred embodiment can provide that the movable furniture part is movable by a spring-loaded and / or electrically driven ejection device which is attached to the carrier element. In this case, when attaching the ejection device on the carrier element automatically made an electrical contact to the line. Again, it can be advantageously provided. that when attaching the ejection device on the support element automatically electrical contact is made to the line, wherein the ejection device with Piercingstiften contacted the electrical line.

Preferably, it can further be provided that the carrier element carries at least one ejection device and a power supply unit, and the ejection device and the power supply unit are assigned to the same movable furniture part. Alternatively, it can also be provided that the carrier element carries at least one power supply unit and an ejection device, which correspond with different movable furniture parts.

The carrier element is preferably arranged in vertical alignment at the rear region of the furniture body inside. This is not to exclude that other orientations and attachment forms of the carrier element in the range of the furniture are possible. In addition, an adjustability of the support element may be provided from and to the furniture body.

The basic idea of the present invention is therefore to use an already known carrier element (also) for the power supply for a power consumer arranged in or on a drawer. The advantage here is especially the modular use of the support element for power supply unit, ejector, etc., which correspond to the respective desired drawers and tool-less in a current-conducting contact with an electrical line - which is preferably integrated in the support element - can be brought.
