Abstract

An arrangement for guiding at least one movable furniture part includes a guide rail to be mounted on the fixed furniture part, a guide device to be coupled to the movable furniture part, and a preferably substantially cylindrical, load-transmitting rolling body. The guide rail has a guide track, on which the load-transmitting rolling body is mounted in a movable manner. The guide track has a parking position for the load-transmitting rolling body, and the parking position corresponds to an end position of the movable furniture part relative to the fixed furniture part. The load-transmitting rolling body and the guide track are designed such that the guide track can be deformed in this region, a depression being formed in the process, and the load-transmitting rolling body is substantially dimensionally stable.

First claim

The invention claimed is:

1. An arrangement comprising:
a stationary furniture part,
a movable furniture part movable relative to the stationary furniture part,
a guide rail to be mounted to the stationary furniture part, and
a guide device to be coupled to the moveable furniture part, the guide device having a load-transmitting rolling body,
wherein the guide rail has a track on which the load-transmitting rolling body is moveably mounted, the track having a parking position for the load-transmitting rolling body, and the parking position corresponds to an end position of the moveable furniture part relative to the stationary furniture part,
wherein the track of the guide rail has a plastic contact portion and a support structure supporting the plastic contact portion and non-integrated with the plastic contact portion,
wherein the load-transmitting rolling body and the track at least in a region of the parking position are configured such that the plastic contact portion of the track is deformable to form a depression and the load-transmitting rolling body is substantially stable in shape,
wherein a hardness of the load-transmitting rolling body is greater than a hardness of the plastic contact portion of the track at least in the region of the parking position.

2. The arrangement as set forth in claim 1 , wherein the contact portion is replaceable and/or has a thickness of 1 mm to 8 mm.

3. The arrangement as set forth in claim 1 , further comprising a securing element configured to fix the contact portion to the guide rail.

4. The arrangement as set forth in claim 3 , wherein the securing element is configured to at least one of:
(i) be substantially U-shaped and/or have a spring element and/or a friction element for increasing the friction at a contact contour formed as a groove of the guide rail,
(ii) have an actuating element by which the securing element and the contact portion connected thereto are moveable, and
(iii) be releasably fixed to the contact portion by a latching device having a latching recess and a latching projection.

5. The arrangement as set forth in claim 1 , wherein the load-transmitting rolling body has at least a portion formed from steel.

6. The arrangement as set forth in claim 1 , wherein the track is substantially irreversibly deformable thereby forming the depression at the parking position of the load-transmitting rolling body, and/or
wherein the load-transmitting rolling body is moveable with the application of a force out of the depression formed in the region of the parking position in the track.

7. The arrangement as set forth in claim 1 , wherein the track has at least two different material portions, wherein a first material portion is arranged in the region of the parking position and a second material portion is arranged in a dynamic region adjoining the region of the parking position.

8. The arrangement as set forth in claim 1 , wherein at least a portion of the track has a concave configuration in cross-section, and/or
wherein the load-transmitting rolling body has a peripheral surface having at least a portion with a convex configuration in cross-section.

9. The arrangement as set forth in claim 1 , further comprising a carrier on which the moveable furniture part is to be pivotably mounted, and to be coupled to the guide device.

10. The arrangement as set forth in claim 1 , further comprising a transverse rail to be arranged transversely to the guide rail and a carriage to be coupled to the moveable furniture part and to be mounted displaceably on the transverse rail.

11. The arrangement as set forth in claim 1 , wherein the moveable furniture part is a furniture door, and the stationary furniture part has an internal space and a side compartment having a shaft shape,
wherein the guide rail and the guide device are configured and arranged to guide the furniture door relative to the stationary furniture part between a closed position outwardly covering the internal space and an open position at least partially sunk in the side compartment and in which the internal space is freely accessible to a user.

12. The arrangement as set forth in claim 11 , wherein the guide rail extends at least partially in a depth direction of the side compartment, and the parking position of the load-transmitting rolling body corresponds to an end position of the furniture door of being substantially completely arranged in the side compartment.

13. The arrangement as set forth in claim 12 , wherein the stationary furniture part has a side surface which at least partially delimits the side compartment and at which the guide rail is at least partially arranged.

14. The arrangement as set forth in claim 12 , wherein the parking position is a first parking position, the track having a second parking position for a second load-transmitting rolling body to be parked at a position of the furniture door, wherein the furniture door is arranged substantially parallel to and substantially completely outside the side compartment of the stationary furniture part.

15. The arrangement as set forth in claim 1 , wherein the load-transmitting rolling body is cylindrical.

16. The arrangement as set forth in claim 1 , wherein the support structure is a steel support structure, and the plastic contact portion is formed of polyoxymethylene.

17. An arrangement comprising:
a stationary furniture part,
a movable furniture part movable relative to the stationary furniture part,
a guide rail to be mounted to the stationary furniture part, and
a guide device to be coupled to the moveable furniture part, the guide device having a load-transmitting rolling body,
wherein the guide rail has a track on which the load-transmitting rolling body is moveably mounted, the track having a parking position for the load-transmitting rolling body, and the parking position corresponds to an end position of the moveable furniture part relative to the stationary furniture part,
wherein the track of the guide rail has a plastic contact portion and a support structure supporting the plastic contact portion and non-integrated with the plastic contact portion,
wherein the load-transmitting rolling body and the track at least in a region of the parking position are configured such that the plastic contact portion of the track is deformable to form a depression and the load-transmitting rolling body is substantially stable in shape, and
wherein the depression is concave within the region of the parking position of the track.

18. An arrangement comprising:
a stationary furniture part,
a movable furniture part movable relative to the stationary furniture part,
a guide rail to be mounted to the stationary furniture part, and
a guide device to be coupled to the moveable furniture part, the guide device having a load-transmitting rolling body,
wherein the guide rail has a track on which the load-transmitting rolling body is moveably mounted, the track having a parking position for the load-transmitting rolling body, and the parking position corresponds to an end position of the moveable furniture part relative to the stationary furniture part,
wherein the track of the guide rail has a plastic contact portion and a support structure supporting the plastic contact portion and non-integrated with the plastic contact portion,
wherein the load-transmitting rolling body and the track at least in a region of the parking position are configured such that the plastic contact portion of the track is deformable to form a depression and the load-transmitting rolling body
