Abstract

In a guide device for guiding a furniture part, in particular a drawer, an extractable or the like, which can be moved relative to a furniture body, having at least one guide unit which comprises a body rail which can be fastened on the furniture body, a central rail mounted displaceable relative to the body rail by a lower rail guide, and an extraction rail mounted displaceable relative to the central rail by an upper rail guide and is connectable to an extractable, lower rail support for supporting the central rail on the body rail being provided in addition to the lower rail guide, and upper rail support for supporting the extraction rail on the central rail being provided in addition to the upper rail guide, the lower rail support and the upper rail support are actively connected to one another.

First claim

What is claimed is:

1 . A guide device for guiding an extractable furniture part that is moveable relative to a furniture body, comprising:
at least one guide unit comprising:
a body rail configured to be fastened on the furniture body;
an upper rail guide and a lower rail guide;
a central rail mounted displaceably relative to the body rail via the lower rail guide;
an extractable, lower rail support configured to support the central rail on the body rail;
an extraction rail mounted displaceably relative to the central rail via the upper rail guide, the extraction rail being connectable to the lower rail support; and
an upper rail support configured to support the extraction rail on the central rail, wherein the lower rail support and the upper rail support are actively connected to one another.

2 . The guide device according to claim 1 , wherein the lower rail support and the upper rail support interlock indirectly with one another.

3 . The guide device according to claim 1 , wherein the lower rail support comprises a lower rack/pinion combination comprising at least one lower rack and at least one lower pinion that, during insertion or extraction, can be brought into interlocking engagement with, or is in interlocking engagement with, the lower rack.

4 . The guide device according to claim 3 , wherein the lower pinion is mounted rotatably on the central rail, and the lower rack includes upwardly directed teeth on the lower rail guide.

5 . The guide device according to claim 1 , wherein the upper rail support comprises an upper rack/pinion combination comprising at least one upper rack and at least one upper pinion that, during insertion or extraction, can be brought into interlocking engagement with, or is in interlocking engagement with, the upper rack, the upper pinion being rotatably mounted on the central rail, and the upper rack being arranged with downwardly directed teeth on the upper rail guide.

6 . The guide device according to claim 5 , wherein the lower pinion and the upper pinion are actively connected to one another, the lower and upper pinions being arranged offset in height relative to one another.

7 . The guide device according to claim 6 , wherein the lower and upper pinions are driven and interlock directly or indirectly with one another, the lower and upper pinions being driven by the lower and upper racks.

8 . The guide device according to claim 7 , further comprising an odd number of further transmission pinions interconnected between the lower and upper pinions, wherein the odd number is at least one.

9 . The guide device according to claim 8 , wherein adjacent ones of the further transmission pinions are interlocking with one another and are arranged running counter to one another.

10 . The guide device according to claim 8 , wherein the further transmission pinions are not in direct engagement with the lower and upper racks.

11 . The guide device according to claim 6 , wherein the lower and upper pinions are arranged running in the same direction as one another.

12 . The guide device according to claim 6 , wherein the lower and upper pinions are configured in a synchronizing manner.

13 . The guide device according to claim 6 , wherein the lower and upper pinions are connected to one another via a chain or a toothed belt.

14 . The guide device according to claim 5 , wherein the lower and upper pinions are connected to one another via step-down or step-up gearing.

15 . An item of furniture, comprising:
the guide device according to claim 1 ; a furniture body; and a furniture part moveable relative to the furniture body and guided by the guide device.
