Abstract

A fastening element consisting of a cage element with a nut arranged therein that is held by a fastening flange in the cage element. The cage element has a wall element which can be moved in an axial direction and shields the seat area of the cage element against the penetration of adhesive while mounting the fastening element on a component surface.

First claim

The invention claimed is:

1. A cage element for a fastening element having the following features:
a. a first and a second face arranged opposite each other which are connected to each other by a peripheral boundary wall in order to define a seat area for a connecting element,
a1. the first face at least partially forms an adhesive surface for fastening the cage element to a component,
a2. the second face has an installation opening for the connecting element, wherein

b. the connecting element can be seated in the seat area through the installation opening and held there floatingly in a form-fit manner,
c. a wall element is shiftably arranged in the seat area of the cage element, and at least partially radially adjacent to the boundary wall, in which
d. the wall element is movable perpendicular to the adhesive surface between a position that projects axially beyond the first face and a position seated in the seat area.

2. The cage element according to claim 1 in which the wall element in the projecting position forms a movable collar adjacent to the adhesive surface that prevents the penetration of adhesive into the seat area.

3. The cage element according to claim 2 , in which the seat area has at least one radial bulge by which the connecting element can be inserted through the installation opening.

4. The cage element according to claim 2 , in which the connecting element is a threaded sleeve with an asymmetrical, plate-like end face.

5. The cage element according to claim 2 , in which the cage element consists of transparent plastic.

6. The cage element according to claim 2 , in which the wall element consists of metal or plastic so that the boundary wall is stabilized.

7. The cage element according to claim 2 in which the wall element is held in a friction-locked fit adjacent to the boundary wall.

8. The cage element according to claim 2 , in which the adhesive surface has a plurality of projections which serve as spacers to a component surface.

9. The cage element according claim 1 , in which the seat area has at least one radial bulge by which the connecting element can be inserted through the installation opening.

10. The cage element according to claim 9 , in which the connecting element is a threaded sleeve with an asymmetrical, plate-like end face.

11. The cage element according to claim 9 , in which the cage element consists of transparent plastic.

12. The cage element according to claim 1 , in which the connecting element is a threaded sleeve with an asymmetrical, plate-like end face.

13. The cage element according to claim 1 , in which the cage element consists of transparent plastic.

14. The cage element according to claim 1 , in which the wall element consists of metal or plastic so that the boundary wall is stabilized.

15. The cage element according to claim 1 in which the wall element is held in a friction-locked fit adjacent to the boundary wall.

16. The cage element according to claim 1 , in which the adhesive surface has a plurality of projections which serve as spacers to a component surface.

17. A fastening element that has the following features:
a. a cage element according to claim 1 , and
b. the connecting element that can be seated in the seat area through the installation opening in the second face, or through an opening in the first face, and that is held floatingly in a form-fit manner in the seat area.

18. A component with a component opening on which an adjacent cage element is adhered to a component surface, wherein the cage element includes:
a. a first and a second face arranged opposite each other which are connected to each other by a peripheral boundary wall in order to define a seat area for a connecting element,
a1. the first face at least partially forms an adhesive surface for fastening the cage element to a component,
a2. the second face has an installation opening for the connecting element, wherein

b. the connecting element can be seated in the seat area through the installation opening and held there floatingly in a form-fit manner, and
c. a wall element is shiftably arranged in the seat area of the cage element, and at least partially radially adjacent to the boundary wall, in which
d. the wall element is movable perpendicular to the adhesive surface between a position that projects axially beyond the first face and a position seated in the seat area.

19. The component of claim 18 which also includes the connecting element seated in the seat area through the installation opening in the second face, or through an opening in the first face, and that is held floatingly in a form-fit manner in the seat area.
