Abstract

A guide apparatus for guiding a furniture part, in particular a sliding door or folding-sliding-door, including a guide rail and a chassis which can be connected to the furniture part and which can travel on the guide rail. The chassis has a load-bearing roller, mounted about a first rotation axis, for supporting the weight of the furniture part and a supporting roller for laterally guiding the furniture part. The supporting roller is rotatably mounted about a second rotation axis which is oriented transverse to the first rotation axis, and a support apparatus is separate from the at least one supporting roller, and is designed to relieve the supporting roller in an end position of the at least one guide rail against a transverse force acting laterally, i.e. substantially parallel to the first rotation axis.

First claim

The invention claimed is:

1. A guide device for guiding a furniture part, comprising:
at least one guide rails; and
a chassis which can be connected to the furniture part, the chassis being connected to the at least one guide rail such that the chassis can travel on the at least one guide rail,
wherein the chassis includes
at least one carrying roller mounted about a first axis of rotation for supporting the weight of the furniture part, the at least one carrying roller being arranged to move on a first surface in the at least one guide rail,
at least one supporting roller for laterally guiding the furniture part, wherein the at least one supporting roller is mounted rotatably about a second axis of rotation aligned transverse to the first axis of rotation, the at least one supporting roller being arranged to move on a second surface in the at least one guide rail, and
at least one support device which is separate from the at least one supporting roller, the at least one support device being connected to the at least one guide rail and being configured to relieve a pressure of a transverse force acting substantially parallel to the first axis of rotation on the at least one supporting roller when the chassis is in at least one end position at an end of the at least one guide rail,

wherein
the chassis includes at least one carrier aligned substantially parallel to the second axis of rotation, and the furniture part can be connected to the at least one carrier of the chassis, or
the at least one guide rail includes at least two guide rails which are arranged substantially transverse to each other.

2. The guide device according to claim 1 , wherein the at least one support device has a first part and a second part, the first part being movable relative to the second part, and wherein the first part and the second part are coupled to each other in a first position in order to relieve the pressure of the transverse force on the at least one supporting roller, and are decoupled from each other at least in a second position.

3. The guide device according to claim 2 , wherein the first part of the at least one support device is connected to the chassis so as to move together with the chassis, or the second part of the at least one support device is fixed to the at least one guide rail.

4. The guide device according to claim 1 , wherein the at least one support device has at least one ramp.

5. The guide device according to claim 4 , wherein the at least one ramp is aligned substantially parallel to the second axis of rotation of the at least one supporting roller, or
the at least one ramp is aligned at an angle to a longitudinal direction of the at least one guide rail.

6. The guide device according to claim 1 , wherein the at least one support device has at least one rolling body.

7. The guide device according to claim 6 , wherein the at least one support device has a first part and a second part, the first part being movable relative to the second part, and wherein the first part and the second part are coupled to each other in a first position in order to relieve the pressure of the transverse force on the at least one supporting roller, and are decoupled from each other at least in a second position,
wherein the first part of the at least one support device includes the at least one rolling body, and the second part of the at least one support device has a U-shaped profile which can be detachably coupled to the at least one rolling body of the first part of the at least one support device.

8. The guide device according to claim 6 , further comprising at least one mounting device on which the at least one rolling body is rotatably mounted, wherein the mounting device has a base part and a bearing pin arranged thereon.

9. The guide device according to claim 8 , wherein
the base part has at least one extrusion, in which the bearing pin is arranged, or
the base part has at least one through-hole which is formed conical in a cross section, and the bearing pin has a corresponding mating shape, or
the bearing pin and the base part are connected to each other at a connection point and are pressed together at the connection point.

10. The guide device according to claim 8 , wherein the bearing pin has a first end region and a second end region, and wherein the at least one rolling body is rotatably mounted on aon the first end region and the at least one supporting roller is rotatably mounted the second end region.

11. The guide device according to claim 10 , wherein
the first and second end regions protrude in different directions from the base part, or
a spacer is provided which spaces the at least one supporting roller apart from the base part.

12. The guide device according to claim 1 , wherein the at least one support device has at least one sliding body.

13. The guide device according to claim 1 , wherein the at least one support device is configured to prevent contact between the at least one supporting roller and the at least one guide rail when the chassis is in the at least one end position.

14. The guide device according to claim 1 , wherein the at least one guide rail includes regions which consist of aluminum, or
a lateral surface of the at least one supporting roller consists of plastic, or
the at least one support device has at least one steel part which is fixed to the at least one guide rail.

15. The guide device according to claim 1 , wherein the at least one support device has at least one pin.

16. A piece of furniture comprising:
a furniture part;
a furniture carcass; and
the guide device according to claim 1 , wherein the at least one guide rail is mounted on the furniture carcass, and the chassis is connected to the furniture part.

17. The piece of furniture according to claim 16 , wherein
the piece of furniture has at least one interior which can be at least partially covered by the at least one furniture part, and in which kitchen furniture or kitchen appliances can be arranged, or
the piece of furniture has at least one cavity extending in a depth direction of the piece of furniture for at least partially receiving the at least one furniture part.

18. A method for guiding a furniture part relative to a furniture carcass by the guide device according to claim 1 , comprising:
supporting the weight of the furniture part by the at least one carrying roller of the chassis;
laterally guiding the furniture part by the at least one supporting roller during a movement of the furniture part along the at least one guide rail; and
relieving a pressure of a transverse force acting substantially parallel to the first axis of rotation on the at least one supporting roller is relieved by the at least one support device when the chassis is in the at least one end position.

19. The method according to claim 18 , wherein the at least one support device prevents contact between the at least one supporting roller and the at least one guide rail when the chassis is in the at least one end position.

20. The method according to claim 18 , wherein the furniture part is a sliding door or a folding sliding door.

21. The guide device according to claim 1 , wherein the furniture part is a sliding door or folding sliding door, and
the chassis includes the at least one carrier, and the furniture part can be connected to the at least one carrier of the chassis via at least one hinge.

22. A guide device for guiding a furniture part, comprising:
at least one g
