Abstract

A rail bar for a drawer includes an end to be connected to a wall element, in particular a front panel or a rear wall, of a drawer, and a length adjustment element which is movable relative to the rail bar in the longitudinal direction of the rail bar in order to cover a gap occurring between the end of the rail bar and the wall element in a connected state of the rail bar to the wall element. A spring element is supported on a stationary part of the rail bar and pushes the length adjustment element towards a maximum position, in which the length adjustment element lengthens the rail bar to a maximum extent.

First claim

The invention claimed is:

1. A rail bar for a drawer, comprising:
an end to be connected to a wall element;
at least one length adjustment element movable in a longitudinal direction of the rail bar relative to the rail bar in order to cover a gap occurring between the end of the rail bar and the wall element in a connected state of the rail bar to the wall element; and
at least one spring element which is supported on at least one stationary part of the rail bar and exerts a biasing force which pushes the at least one length adjustment element in a direction of a maximum position in which the at least one length adjustment element prolongs the rail bar to a maximum extent,
wherein the at least one length adjustment element is movable against the biasing force of the at least one spring element to a minimum position in which the at least one length adjustment element does not project from the end of the rail bar in the longitudinal direction.

2. The rail bar according to claim 1 , wherein the at least one length adjustment element projects region-wise beyond the end of the rail bar in the longitudinal direction in positions in which the at least one length adjustment element prolongs the rail bar.

3. The rail bar according to claim 1 , wherein the rail bar has at least one cavity and the at least one length adjustment element is arranged region-wise in the at least one cavity.

4. The rail bar according to claim 1 , wherein the at least one spring element is formed on the at least one length adjustment element.

5. The rail bar according to claim 1 , wherein the at least one stationary part is in the form of an insert arranged in an interior of the rail bar.

6. The rail bar according to claim 1 , wherein a spacing between the maximum position and the minimum position is between 1 mm and 3 mm.

7. The rail bar according to claim 6 , wherein the spacing between the maximum position and the minimum position is between 1.5 mm and 2 mm.

8. The rail bar according to claim 1 , further comprising at least one abutment for limiting the movement of the at least one length adjustment element relative to the rail bar.

9. The rail bar according to claim 1 , wherein the rail bar has a fixing device for a furniture fitment which is to be mounted to the wall element of the drawer.

10. The rail bar according to claim 9 , wherein the fixing device is configured to fix a furniture fitment at a predetermined position relative to the rail bar.

11. The rail bar according to claim 10 , wherein the fixing device is configured to releasably fix a furniture fitment at the predetermined position relative to the rail bar.

12. The rail bar according to claim 1 , further comprising at least one guide for guiding the at least one length adjustment element upon a movement relative to the rail bar.

13. The rail bar according to claim 1 , wherein the rail bar is of a substantially quadrangular configuration in cross-section.

14. An arrangement comprising:
the rail bar according to claim 1 ; and
at least one wall element, wherein the end of the rail bar is connected to the at least one wall element and defines a gap between the end of the rail bar and the at least one wall element, the gap being covered by the at least one length adjustment element.

15. The arrangement according to claim 14 , further comprising a furniture fitment which is separate from the at least one length adjustment element and which is fixed to the at least one wall element and to the rail bar.

16. The arrangement according to claim 15 , wherein the furniture fitment is fixed to the at least one wall element and to the rail bar at a predetermined position relative to the rail bar.

17. The arrangement according to claim 14 , further comprising a drawer side wall, wherein the rail bar is arranged above the drawer side wall.

18. The arrangement according to claim 17 , wherein the rail bar is arranged at a spacing above the drawer side wall.

19. A drawer including the arrangement according to claim 14 .

20. The arrangement according to claim 14 , wherein the at least one wall element includes a front panel or a rear wall of a drawer.

21. The rail bar according to claim 1 , wherein the end of the rail bar is configured to be connected to a front panel or a rear wall of a drawer.
