Abstract

A pull-out guide has a guide rail, a running rail, which is mounted in a displaceable manner on the guide rail, and a braking device disposed between the guide rail and the running rail for braking the movement of the running rail relative to the guide rail. The braking device has at least one friction element, which is arranged between the running rail and the guide rail and can be displaced along a sliding surface by way of a contact pressure. The pull-out guide can thus be braked with continuous forces over a long period of time.

First claim

What is claimed is:

1. A pull-out guide ( 1 ) comprising: a guide rail ( 2 ), a running rail ( 3 ) displaceably mounted on the guide rail ( 2 ), and a braking device disposed between the guide rail ( 2 ) and the running rail ( 3 ) for braking a movement of the running rail ( 3 ) relative to the guide rail ( 2 ),
wherein the braking device comprises at least one friction element ( 6 ) arranged between the running rail ( 3 ) and the guide rail ( 2 ), which friction element ( 6 ) is displaceable along a sliding surface with a contact pressure,
wherein the friction element ( 6 ) is configured to be fixed to the running rail ( 3 ) or the guide rail ( 2 ), while the sliding surface is integrally formed in one piece with the respective other rail and the friction element ( 6 ) is configured to be latched at at least one position on an embossment ( 23 ), profiling or recess ( 25 ) on the guide rail ( 2 ) or the running rail ( 3 ),
wherein the running rail ( 3 ) is configured to be latched relative to the guide rail ( 2 ) at opposite end positions, and
wherein the friction element ( 6 ) is held on a bent-over web ( 32 ) formed integrally in one piece with the guide rail ( 2 ) or the running rail ( 3 ).

2. The pull-out guide according to claim 1 , wherein the friction element ( 6 ) presses the guide rail ( 2 ) and the running rail ( 3 ) apart perpendicular to a longitudinal direction of the guide rail and the running rail.

3. The pull-out guide according to claim 1 , wherein the friction element ( 6 ) has at least one contact surface ( 8 ) on a U- or V-shaped section which rests against the sliding surface.

4. The pull-out guide according to claim 1 , wherein the bent-over web ( 32 ) is oriented at an angle between 5° and 40° with respect to the longitudinal direction of the guide rail ( 2 ) and the running rail ( 3 ).

5. The pull-out guide according to claim 1 , wherein the friction element ( 6 ) has two latching webs ( 9 ) which engage around the bent-over web ( 32 ) for fixing the friction element on the bent-over web.

6. The pull-out guide according to claim 1 , wherein the bent-over web ( 32 ) has a widening end section ( 33 ).

7. The pull-out guide according to claim 1 , wherein the bent-over web ( 32 ) can be bent to adjust a braking force.

8. The pull-out guide according to claim 1 , wherein the friction element ( 6 ) has a spring ( 40 ).

9. The pull-out guide according to claim 1 , wherein the friction element ( 6 ) has a plastic body.

10. The pull-out guide according to claim 9 , wherein a metallic spring ( 40 ) is embedded in the plastic body.

11. The pull-out guide according to claim 1 , wherein the running rail ( 3 ) and the guide rail ( 2 ) are designed to be C-shaped in cross-section with mutually facing limbs ( 21 , 31 ) on which rolling elements ( 4 ) are held in a displaceable manner.

12. A vehicle console having a cover which is held in a displaceable manner via at least one pull-out guide ( 1 ) according to claim 1 .

13. A furniture item or household appliance having at least one drawer element which is displaceably held in a carcass via at least one pull-out guide ( 1 ) according to claim 1 .
