Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a furniture drawer that can be supported in a furniture main body so as to be able to be drawn out, and furniture having at least one drawerable furniture drawer.

[0002]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a furniture drawer which avoids a permanent line in the form of an electric cable from the furniture body to the drawer.

[0003]

The furniture drawer according to the invention comprises at least one storage device arranged in or next to the drawer in order to avoid a permanent line in the form of an electric cable from the furniture body to the drawer. A device for transmitting electric energy to the body is provided.

Using the rechargeable power storage unit as described above,
Electrical equipment for or in the drawer,
Preferably, it is possible to automatically prepare the energy supply for household appliances, preferably the transfer of electrical energy for charging the chargeable electrical storage body only when the drawer is closed. Then, when the drawer is pulled out, the charged electrical storage supplies the electrical consumer, such as a lamp or a drive motor, or the household appliances that charge when the drawer in the drawer is closed. You can

In order to realize a device for transmitting electrical energy as described above, preferably a contactless relay, preferably an inductive coupler or a plug contact, is provided on the rear wall of the drawer, which is the drawer. When it is closed, it will automatically contact the body. The power supply is provided, for example, via a transformer which produces a low-voltage region, which is harmless to humans, preferably in the region of 25 V, in the region of the draw from the normally used AC power grid.

The above-mentioned electrical inductive repeaters are already known per se, for example in electric toothbrushes, and therefore need not be described in detail.

The rechargeable power storage unit can be built in or incorporated in the drawer wall portion or the drawer bottom portion in view of space.

However, it is also possible to use a conventional metal guide rail in the drawer for the current transmission, in which case the body-side guide rail connected to the power supply is advantageously used on the drawer side. Sliding contacts are provided to connect to the guide rails.

When using an electrical guide rail as described above, cables can be avoided. In this case, it is possible to continuously supply electric power into the drawer at each position, so that a rechargeable power storage unit is basically unnecessary in this modification of the present invention.

Rather, electrical consumers, such as lamps or motors, can always be supplied directly. Of course, it is also possible to charge household appliances inside the drawer with the storage battery via the electrified guide rails as described above.

A particularly preferred embodiment of the invention results from the fact that at least one light source is designed as a light emitting diode (LED). The light emitting diode combines a compact structure with low power consumption and good luminous efficiency.

In addition to being supplied from the usual power grid, it is also conceivable to provide the drawer or furniture body with solar cells according to another variant of the invention. Through the solar cell as described above, it is possible in a cost-effective manner, in particular, to supply power to the electrical consumer in or next to the drawer without the need to connect to a power grid, preferably corresponding to the solar cell. A rechargeable power storage unit is provided that is charged via the charge controller.

A particularly preferred embodiment of the invention results from the fact that at least one electrical storage body is a rechargeable battery. Since the rechargeable battery as described above is obtained in many different embodiments, the rechargeable battery can be appropriately selected depending on the expected power consumption and the space provided.

Another preferred embodiment of the invention results from the fact that at least one rechargeable battery is a capacitor. Even after long-term use, unlike the case of a storage battery, for example, the memory effect of decreasing the storage capacity does not occur, so that the storage capacity of the capacitor is hardly reduced.
