Abstract

The invention relates to a holding device for adhesive fastening to a surface, comprising a holding element and an allocated fastening element, wherein the holding element has a base plate having a rear surface and a threaded bolt protruding over the base plate, wherein the fastening element can be attached to the threaded bolt of the holding element, wherein the fastening element has a continual opening and is elastic at least in the region of the opening, and wherein the opening has an inner diameter which, in relation to an outer diameter of the threaded bolt, is designed such that the fastening element can be both placed on and removed from and, by a rotating motion, screwed onto or off of the threaded bolt.

Claims

1. A holding device for adhesive fastening to a surface having a holding body and an associated fastening element, wherein the holding body has a base plate with a rear surface and a threaded bolt protruding above the base plate, wherein the fastening element can be attached to the threaded bolt of the holding body, wherein the fastening element has a through opening and is designed so that it is elastic at least in the region of the opening, wherein the opening has an internal diameter which is configured in relation to the external diameter of the threaded bolt in such a way that the fastening element can both be pushed onto the threaded bolt and pulled off it by a linear movement and be screwed onto it and unscrewed from it by a turning movement.

2. The holding device as claimed in claim 1, wherein the fastening element can be deformed, at least in the region of the opening, by a force in such a way that the fastening element can, in a deformed state, be pushed onto the threaded bolt and pulled off it and, in an undeformed state, can be screwed onto or unscrewed from the threaded bolt.

3. The holding device as claimed in claim 1, wherein the fastening element is made from an elastomer, optionally from a thermoplastic elastomer.

4. The holding device as claimed in claim 3, wherein the elastomer has a Shore A hardness of between 58 and 94.

5. The holding device as claimed in claim 1, wherein an inner surface, limiting the through opening, of the fastening element has a profile of a helical rib.

6. The holding device as claimed in claim 5, wherein the profile is designed on a helical curve with the pitch P and an angular range φ

of at least 270° and

no more than 360°

about an axis of the fastening element.

7. The holding device as claimed in claim 1, wherein the threaded bolt has an external thread with a pitch P less than 1.5 mm.

8. The holding device as claimed in claim 1, wherein the threaded bolt has a nominal diameter D of between 2 mm to 8 mm.

9. The holding device as claimed in claim 1, wherein the external thread of the threaded bolt has a thread profile depth which is reduced compared with a standard thread.

10. The holding device as claimed in claim 1, wherein a support plate of the holding body bears the threaded bolt and can be displaced relatively with respect to the base plate, optionally in the direction of the main load.

11. The holding device as claimed in claim 1, wherein an outer profile of the fastening element is designed with a sawtoothed, triangular or double-triangular shape.

12. The holding device as claimed in claim 1, comprising at least one double-sided self-adhesive strip.

13. The holding device as claimed in claim 12, wherein the fastening element can be pulled off with a tensile force F2 of between at least [2n×

B] N/cm and no more than [10n×

B] N/cm, wherein n is the number of the double-sided self-adhesive strips used and B the width of one of the double-sided self-adhesive strips.

14. The holding device as claimed in claim 12, wherein the double-sided self-adhesive strip has a width B and a length L, wherein the length L is greater than the width B, and an external thread of the threaded bolt has a pitch of no more than 0.01×

L.

15. The holding device as claimed in claim 14, wherein a torque required to screw on or unscrew the fastening element is no more than [100n×

B] N, wherein n is the number of double-sided self-adhesive strips and B is the width of one of the double-sided self-adhesive strips.
