Abstract

The invention relates to a device for compensating tolerances between a first component and a second component to be screwed to it by means of a connecting screw, comprising a base element and a compensation element that is in thread engagement with the base element, the thread engagement being non-self-locking in such a way that the compensation element moves out of the base element when the connecting screw exerts an axial force on the compensation element.

First claim

What is claimed is:

1. Device for compensating tolerances between a first component and a second component to be screwed to it by means of a connecting screw, the device comprising a base element and a compensation element that is in threaded engagement with the base element, the compensation element including at least two segments which are axially displaceable relative to one another and are connected to one another by connecting elements with a material fit, form fit, or force fit, the segments being held axially offset from one another by the connecting elements in an initial or idle state of the compensation element;
the threaded engagement between the base element and the compensation element being non-self-locking in such a way that the compensation element moves out of the base element in an insertion direction of the connecting screw when the connecting screw exerts an axial force acting in the insertion direction on the compensation element.

2. The device according to claim 1 ,
wherein the base element and the compensation element form a steep thread.

3. The device according to claim 1 ,
wherein the base element forms an internal thread and the compensation element forms an external thread.

4. The device according to claim 1 ,
wherein the base element forms two opposite thread sections.

5. The device according to claim 4 ,
wherein the base element forms two opposite thread sections with the same pitch.

6. The device according to claim 1 ,
wherein the compensation element forms a multi-start thread.

7. The device according to claim 6 ,
wherein the compensation element forms a multi-start thread which comprises a plurality of groups distributed in the circumferential direction with each of the thread sections being arranged in parallel to one another.

8. The device according to claim 1 ,
wherein the compensation element forms a contact surface for a head of the connecting screw.

9. The device according to claim 1 ,
wherein the compensation element is cup-shaped.

10. The device according to claim 1 ,
wherein the compensation element comprises a hollow cylindrical section which at its one end merges into a bottom section which has a passage for the connecting screw and defines a contact surface for a head of the connecting screw.

11. The device according to claim 10 ,
wherein the one end is its end facing the second component.

12. The device according to claim 1 ,
wherein at least two segments are at least approximately partially hollow cylindrical segments.

13. The device according to claim 1 ,
wherein the connecting elements comprise spring elements.

14. The device according to claim 13 ,
wherein the spring elements are spring elements formed in one piece with the segments.

15. The device according to claim 1 ,
wherein thread sections of the one segment and thread sections of the other segment are arranged such that they together form the thread of the compensation element when the compensation element is in its initial or idle state.

16. The device according to claim 1 ,
wherein the compensation element is formed from a plastic material and/or wherein the compensation element is formed from a plastic material and is an injection molded part; and/or
wherein the base element is formed from a plastic material and/or the base element is formed from a plastic material and is an injection molded part.

17. The device according to claim 1 ,
wherein the base element is formed by the first component or is firmly connected to the first component.
