Abstract

An adhesive aid and a method for adhering components by use of an adhesive are provided. The adhesive can be found in an adhesive gap between respective adhesive surfaces of the components. At least the first component has an opening which opens into the component adhesive surface. The adhesive aid has an insert portion, which is designed to be inserted into the opening and has an insert outer contour that correlates to an inner contour of the opening, and a displacement portion, which adjoins the insert portion in order to displace adhesive in the adhesive gap. The displacement portion has a protrusion which protrudes past the insert outer contour in the radial direction, and the displacement portion is designed to be flexible, in particular elastic, at least in the region of the protrusion.

First claim

What is claimed is:

1. An adhesive aid for use during adhesive joining of first and second components via an adhesive situated in an adhesive gap between respective adhesive surfaces of the first and second components, at least the first component having an opening that opens to the adhesive surface of the first component, the adhesive aid comprising:
an insert section configured to be inserted into the opening, the insert section having an insert outer contour that corresponds with an inner contour of the opening;
a displacement section adjoining the insert section, the displacement section being configured to displace the adhesive in the adhesives gap, wherein
the displacement section has a protrusion which protrudes past the insert outer contour in a radial direction, and
the displacement section is flexible at least in an area of the protrusion.

2. The adhesive aid according to claim 1 , wherein the displacement section is elastic at least in the area of the protrusion.

3. The adhesive aid according to claim 1 , wherein a length of the displacement section is adapted to a defined thickness of the adhesive gap.

4. The adhesive aid according to claim 1 , wherein the displacement section forms an axial end of the adhesive aid.

5. The adhesive aid according to claim 2 , wherein the displacement section forms an axial end of the adhesive aid.

6. The adhesive aid according to claim 1 , wherein the adhesive aid further comprises a second insert section adjoining the displacement section in the axial direction.

7. The adhesive aid according to claim 1 , wherein the adhesive aid further comprising two or more displacement sections, each of said two or more displacement sections being separated from one another by a respective insert section.

8. The adhesive aid according to claim 1 , wherein the adhesive aid further comprises:
a placing section adjoining the insert section, the placing section having a placing surface to be placed onto a free surface of the first component, the free surface of the first component facing away from the adhesive surface of the first component, and
the placing section being placed around the opening.

9. The adhesive aid according to claim 8 , wherein a length of the insert section corresponds to a thickness of the first component in the area of the opening.

10. The adhesive aid according to claim 1 , wherein the adhesive aid further comprises a handling section configured for handling of the adhesive aid.

11. The adhesive aid according to claim 10 , wherein the handling section adjoins the insert section.

12. The adhesive aid according to claim 1 , wherein the adhesive aid is made completely of an elastic material.

13. The adhesive aid according to claim 12 , wherein the elastic material is silicon or an elastomeric plastic.

14. The adhesive aid according to claim 12 , wherein the adhesive aid is made in one piece.

15. The adhesive aid according to claim 1 , wherein the insert section has an undercut at an end adjoining the displacement section.

16. The adhesive aid according to claim 8 , wherein the insert section has an undercut at an end adjoining the displacement section.

17. A method of joining adhesively a first component with a second component, at least the first component having an opening that opens to an adhesive surface of the first component, the method comprising the acts of:
placing an adhesive aid according to claim 1 in the opening of the first component;
applying a flowable adhesive to the adhesive surface of the first component and/or an adhesive surface of the second component;
placing the first component and the second component together with the respective adhesive surfaces thereof facing one another; and
removing the adhesive aid from the opening.

18. The method according to claim 17 , further comprising the act of exerting a predefined adhesion pressure upon the first and second components upon placing the components together.

19. The method according to claim 18 , wherein the act of inserting the adhesive aid and the act of removing the adhesive aid are carried out from a side of the first component that faces away from the adhesive gap.

20. The method according to claim 17 , wherein the act of inserting the adhesive aid and the act of removing the adhesive aid are carried out from a side of the first component that faces away from the adhesive gap.
