Abstract

A drawer pull-out guide includes a fastening portion having a vertical limb and a transverse limb protruding from the vertical limb. The transverse limb is connected to a limb of the carcass rail, an extension rail is displaceably supported relative to the carcass rail, and a rolling body is arranged between the carcass rail and the extension rail and is supported on a running limb of the carcass rail and/or the extension rail. The limb of the carcass rail has a first limb portion connected to the transverse limb. A second limb portion of the carcass rail, in an unloaded condition of the drawer pull-out guide, is spaced from the transverse limb by a gap, and can be tilted or bent towards the transverse limb. Therefore, a change of relative position between the running limb and the rolling body can be compensated for, and the gap can be reduced.

First claim

The invention claimed is:

1. A drawer pull-out guide, comprising:
a carcass rail to be fixed to a furniture carcass,
a fastening portion for fixing the carcass rail to the furniture carcass, the fastening portion has a vertical limb configured to rest against the furniture carcass and a transverse limb protruding from the vertical limb, wherein the transverse limb of the fastening portion is connected to a limb of the carcass rail, the limb of the carcass rail extending in a longitudinal direction of the carcass rail,
an extension rail displaceably supported relative to the carcass rail in the longitudinal direction,
a rolling body arranged between the carcass rail and the extension rail, the rolling body to be supported on a running limb of the carcass rail and/or a running limb of the extension rail,
wherein the limb of the carcass rail has a first limb portion and a second limb portion, the first limb portion of the carcass rail being connected to the transverse limb of the fastening portion, and the second limb portion of the carcass rail, in an unloaded condition of the drawer pull-out guide, being spaced from the transverse limb of the fastening portion by the formation of a gap, the second limb portion being configured, upon a load of the extension rail about an axis extending in the longitudinal direction, to be tilted or bent in a direction towards the transverse limb, so that a change of the relative position between the running limb and the rolling body, caused by a load of the extension rail in a direction transverse to the longitudinal direction, is at least partially compensated for, and the size of the gap located between the second limb portion of the carcass rail and the transverse limb of the fastening portion is reduced.

2. The drawer pull-out guide according to claim 1 , wherein (i) the first limb portion and the second limb portion, in a mounted condition, are spaced from each other in a height direction, or (ii) the second limb portion, in a mounted condition, protrudes transversely from the first limb portion.

3. The drawer pull-out guide according to claim 1 , wherein at least one of the first limb portion and the second limb portion extends substantially over an entire length of the carcass rail.

4. The drawer pull-out guide according to claim 1 , wherein the first limb portion of the carcass rail is connected to the transverse limb of the fastening portion by a fastening location.

5. The drawer pull-out guide according to claim 4 , wherein the first limb portion of the carcass rail is welded to the transverse limb.

6. The drawer pull-out guide according to claim 1 , wherein the second limb portion is arranged closer to the vertical limb than the first limb portion.

7. The drawer pull-out guide according to claim 1 , wherein a width of the second limb portion, measured in a direction transverse to the longitudinal direction, is at least twice a width of the first limb portion.

8. The drawer pull-out guide according to claim 1 , wherein the carcass rail is configured to be fixed to the furniture carcass by at least two fastening portions spaced from each other in the longitudinal direction.

9. The drawer pull-out guide according to claim 1 , wherein the drawer pull-out guide has a support portion for supporting a drawer bottom.

10. The drawer pull-out guide according to claim 1 , wherein the drawer pull-out guide has a central rail displaceably arranged between the carcass rail and the extension rail.

11. The drawer pull-out guide according to claim 10 , wherein the central rail has a side limb arranged laterally beside a support portion for supporting a drawer bottom, and a transverse limb connected to the side limb, and the transverse limb, in a mounted position, protrudes at least partially below the support portion for the drawer bottom.

12. The drawer pull-out guide according to claim 11 , wherein (i) the side limb, in a mounted position, extends substantially vertically and/or (ii) the transverse limb, in a mounted position, extends substantially horizontally.

13. A drawer comprising the drawer pull-out guide according to claim 1 .
