Abstract

A sliding element works with a guide system having two guide parts that can be moved relative to one another. The sliding element can be fixed to one of the guide parts by an attachment face ( 3 ) and includes, on a face opposite the attachment face ( 3 ), a sliding surface ( 6 ) so as to be slidingly supported on the other guide part. The sliding element includes a first part (I) and a second part ( 2 ) which is mounted so as to be rotatable relative thereto, which parts include a contact surface ( 3 ) for mutual support. The contact surface ( 7 ) is axially inclined in a rotational direction of the second part ( 2 ) counter to the first part (I), and the two parts (I, 2 ) can be locked to one another in various angular positions and the locking can be released.

First claim

The invention claimed is:

1. A sliding element for a guide system having two guide portions which are movable relative to each other, wherein the sliding element can be fixed with a fixing side ( 3 ) to one of the guide portions and at a side opposite the fixing side ( 3 ) has a sliding surface ( 6 ) for slidingly bearing against the other guide portion, the sliding element comprising a first portion ( 1 ) and a second portion ( 2 ) which are mounted rotatably relative to each other about an axis of rotation (D) and have a contact surface ( 7 ) for the two portions ( 1 , 2 ) to bear against each other, and
wherein the contact surface ( 7 ) has an axial inclination in a direction of rotation of the second portion ( 2 ) relative to the first portion ( 1 ) about the axis of rotation (D) so that by rotation of the two portions ( 1 , 2 ) relative to each other the axial overall structural height of the two portions ( 1 , 2 ) which bear against each other at the contact surface ( 7 ) is variable and the two portions ( 1 , 2 ) upon relative rotation thereof about the axis of rotation (D) along their contact surface ( 7 ) can be arrested to each other over an adjustment angle in various angular positions and the arresting action is releasable,
wherein the fixing side ( 3 ) of the sliding element for fixing to one of the guide portions is arranged at a side of the first portion ( 1 ), that faces away from the second portion ( 2 ), and the sliding surface ( 6 ) of the sliding element is arranged at a side of the second portion ( 2 ), that faces away from the first portion ( 1 ), and
wherein the first portion ( 1 ) on a partial circle with respect to the axis of rotation (D) has depressions ( 10 ) or raised portions which co-operate with a projection ( 11 ) or a recess respectively on an elastic element arranged non-rotatably on the second portion ( 2 ) for releasably arresting the two portions ( 1 , 2 ) in the various angular positions by a positively locking engagement.

2. The sliding element as set forth in claim 1 , wherein adjacent angular positions are spaced from each other by equal angles.

3. The sliding element as set forth in claim 1 , wherein the contact surface ( 7 ) has a plurality of inclination regions ( 8 , 9 ) with the axial inclination.

4. The sliding element as set forth in claim 3 , wherein the inclination regions ( 8 , 9 ) are arranged symmetrically over a perimeter with respect to the axis of rotation (D).

5. The sliding element as set forth in claim 3 , wherein there are provided two inclination regions ( 8 , 9 ) which each extend in a direction of rotation about the axis of rotation (D) in mutually adjoining relationship through 180° and the contact of the two portions along each inclination region ( 8 , 9 ) in each angular position extends at least over 20°.

6. The sliding element as set forth in claim 3 , wherein there are provided two inclination regions ( 8 , 9 ) which each extend in a direction of rotation about the axis of rotation (D) in mutually adjoining relationship through 180° and the contact of the two portions along each inclination region ( 8 , 9 ) in each angular position extends at least over 60°.

7. The sliding element as set forth in claim 1 , wherein the depressions ( 10 ) or raised portions of the first portion ( 1 ) and the projection ( 11 ) or the recess on the elastic element ( 12 ) of the second portion are arranged axially and the elastic element is releasable from its engagement into one of the depressions ( 10 ) or raised portions on a partial circle of the first portion ( 1 ) by bending in the axial direction.

8. The sliding element as set forth in claim 7 , wherein the elastic element ( 12 ) in a bending state required for release of the engagement does not project beyond an outwardly facing end of the second portion ( 2 ).

9. The sliding element as set forth in claim 1 , wherein the second portion ( 2 ) has an opening and the elastic element ( 12 ) extends in or below the opening and at a free end has the projection ( 11 ) or the depression.

10. The sliding element as set forth in claim 9 , wherein the elastic element ( 12 ) arranged on the second portion ( 2 ) extends with a free end and the projection ( 11 ) provided thereon or the depression provided thereon into a recess ( 23 ) in an edge region of the opening ( 14 ) of the second portion ( 2 ).

11. The sliding element as set forth in claim 9 , wherein the opening of the second portion ( 12 ) is a through opening ( 14 ) and the first portion ( 1 ) has a through opening ( 15 ) aligning with the through opening ( 14 ) of the second portion ( 2 ).

12. The sliding element as set forth in claim 9 , wherein the elastic element ( 12 ) has an engagement opening ( 16 ) which is central with respect to the axis of rotation and into which a tool ( 13 ) can be inserted for axially pushing or pulling for the purposes of releasing the engagement and rotation for the purposes of adjustment of the angular position.

13. The sliding element as set forth in claim 1 , wherein the elastic element ( 12 ) is formed in one piece on the second portion ( 2 ).

14. The sliding element as set forth in claim 1 , wherein the two portions ( 1 , 2 ) are of a disk-shaped configuration and are mounted rotatably relative to each other by a cylindrical guide at their outer edge regions.

15. The sliding element as set forth in claim 1 , wherein the sliding element is formed by the two portions ( 1 , 2 ), wherein the one outwardly facing side of the portions which bear against each other at their contact surface ( 7 ) forms the sliding surface ( 6 ) of the sliding element and the outwardly facing side opposite thereto is designed for fixing on one of the guide portions.

16. The sliding element as set forth in claim 15 , wherein the sliding surface ( 6 ) is arranged on the second portion ( 2 ) and the side designed for fixing on one of the guide portions is arranged on the first portion ( 1 ).

17. A sliding element for a guide system having two guide portions which are moveable relative to each other, wherein the sliding element can be fixed with a fixing side ( 3 ) to one of the guide portions and at a side opposite the fixing side ( 3 ) has a sliding surface ( 6 ) for slidingly bearing against the other guide portion, the sliding element comprising a first portion ( 1 ) and a second portion ( 2 ) which are mounted rotatably relative to each other about an axis of rotation (D) and have a contact surface ( 7 ) for the two portions ( 1 , 2 ) to bear against each other, and
wherein the contact surface ( 7 ) has an axial inclination in a direction of rotation of the second portion ( 2 ) relative to the first portion ( 1 ) about the axis of rotation (D) so that by rotation of the two portions ( 1 , 2 ) relative to each other the axial overall structural height of the two portions ( 1 , 2 ) which bear against each other at the contact surface ( 7 ) is variable and the two portions ( 1 , 2 ) upon relative rotation thereof about the axis of rotation (D) along their contact surface ( 7 ) can be arrested to each other over an adjustment angle in various angular positions and the arresting action is releasable,
