Abstract

The invention relates to a retaining body for fastening on a surface, wherein the retaining body can be fixed on the surface by means of a double-sided adhesive strip with two opposite retaining surfaces, wherein the retaining body has a basic body with a flat rear surface and a front surface, which is located opposite the rear surface, wherein the front surface of the basic body has formed on it a carrying element which projects from a plane of the basic body, wherein the basic body has, on the front surface, a reinforcing structure with reinforcing elements, wherein the reinforcing elements subdivide the front surface of the basic body into at least two differently sized pressure-exerting surfaces.

Claims

1. A retaining body for fastening on a surface, wherein the retaining body is fixable on the surface by means of a double-sided adhesive strip with two oppositely situated adhesive surfaces, wherein the retaining body comprises a basic body with a flat rear surface and a front surface which is located opposite the rear surface, wherein a carrier element, which protrudes from a plane of the basic body, is realized on the front surface of the basic body, wherein the basic body comprises a reinforcing structure with reinforcing elements on the front surface, wherein the reinforcing elements are formed in one piece with and on the retaining body and divide the front surface of the basic body into at least two differently sized pressing surfaces, wherein, proceeding from a point of applied force, there is optionally provided at least one pressing surface which is arranged in the opposite direction to the main load direction and there is optionally provided at least one pressing surface which is arranged in the main load direction and which is greater than the pressing surface which is arranged in the opposite direction.

2. The retaining body as claimed in claim 1, wherein the reinforcing ribs divide the front surface into at least three pressing surfaces.

3. The retaining body as claimed in claim 1, wherein a first reinforcing element extends from the point of applied force of the carrier element counter to the main load direction.

4. The retaining body as claimed in claim 1, wherein a second reinforcing element and a third reinforcing element extend symmetrically to a symmetry plane through the retaining body, optionally in a mirror-symmetrical manner to a longitudinal axis parallel to the main load direction and through the carrier element.

5. The retaining body as claimed in claim 1, wherein in the view of the front surface of the retaining body, the surface areas of the reinforcing elements are smaller than the surface areas of the pressing surfaces.

6. The retaining body as claimed in claim 1, wherein a normal projection of the carrier element onto the rear surface of the retaining body lies outside the corresponding normal projections of the pressing surfaces.

7. The retaining body as claimed in claim 1, wherein the basic body is scarfed on one side.

8. The retaining body as claimed in claim 1, wherein the retaining body is produced from a fiber-reinforced plastics material.

9. The retaining body as claimed in claim 1, wherein the retaining body is produced on the basis of one of the following materials:

polystyrene (PS), optionally a syndiotactic polystyrene (PS-S), styrene acrylonitrile (SAN), acrylonitrile-styrene-acrylate (ASA), acrylonitrile-butadiene-styrene (ABS) and polyamide (PA).

10. The retaining body as claimed in claim 1, wherein the retaining body is produced on the basis of a polyether ether ketone (PEEK), wherein the retaining body is produced, optionally, by hot pressing.

11. The retaining body as claimed in claim 1, wherein reinforcing elements converge in a base which is arranged in the point of applied force, wherein the carrier element rises out the basic body from said base and the reinforcing elements preferably extend out of the base in a star-shaped or compartment-shaped manner.

12. The retaining body as claimed in claim 1, wherein the carrier element is realized in the form of a sloping elliptical truncated cone or in the form of a rose thorn with a tapering end.

13. The retaining body as claimed in claim 1, wherein the carrier element carries a support plate on its free end.

14. The retaining body as claimed in claim 1, wherein one smaller pressing surface comprises a surface area of between 0.6 cm² and 2.3 cm² and/or two smaller pressing surfaces of the at least three pressing surfaces each comprise a surface area of between 0.6 cm² and 2.3 cm² and/or one larger pressing surface comprises a surface area of at least 2.5 cm².

15. The retaining body as claimed in claim 1, wherein the retaining body is delimited by side edges, wherein positioning notches are realized on the side edges in each case at the same height, optionally at the height of the carrier element.

16. The retaining body as claimed in claim 1, wherein a vent duct which is realized with a V-shaped profile, is provided on the rear surface of the retaining body.

17. The retaining body as claimed in claim 16, wherein the vent duct runs at least in portions under one of the reinforcing elements under the first reinforcing element.

18. A retaining device with a retaining body as claimed in claim 1 and with an adhesive strip which is effective on two sides and is attached on the rear surface of the basic body of the retaining body or on said rear surface.

19. The retaining device as claimed in claim 18, wherein the adhesive strip, which is effective on two sides, comprises a non-adhesive part portion, wherein the non-adhesive part portion projects beyond at least one side of the rear surface of the basic body.

20. A method for installing a retaining device having a retaining body as claimed in claim 1 as well as an adhesive strip, which is effective on two sides and has two oppositely situated sticky adhesive surfaces which are each covered by a protective foil, said method comprising the following steps:

a) moving the first protective foil from the first sticky adhesive surface of the adhesive strip which is effective on two sides;

b) applying the first sticky adhesive surface of the adhesive strip onto a surface;

c) removing the second protective foil from the second sticky adhesive surface of the adhesive strip;

d) placing the rear surface of the retaining body onto the second sticky adhesive surface of the adhesive strip;

e) exerting pressure onto each of the pressing surfaces of the retaining body, wherein the surface moistened by one of the sticky adhesive surfaces of the adhesive strip increases with each exertion of pressure onto a pressing surface.
