Abstract

A functional element of metal having a flange of larger diameter from an attachment surface and a centering section arranged inside the attachment surface and extending away from the flange, characterized in that an adhesive is arranged around the cylindrical section and adjacent to the attachment surface.

First claim

The invention claimed is:

1. A functional element ( 10 ) of metal having a flange ( 14 ) of larger diameter forming an attachment surface ( 12 ) and a centering section ( 16 ) arranged inside the attachment surface and extending away from the flange, an adhesive ( 30 ) is arranged around the centering section ( 16 ) and adjacent to the attachment surface ( 12 ) and at least one recess ( 38 ) is formed in at least one of the flange ( 14 ) and the centering section ( 16 ) to take up excess adhesive, the recess ( 38 ) being a ring recess which is arranged radially outside of the attachment surface ( 12 ) as an axial groove in the flange ( 14 ), the attachment surface ( 12 ) is arranged radially inside a contact surface ( 40 ) and is set back relative to the latter in an axial direction ( 64 ) of the centering section ( 16 ), the contact surface ( 40 ) forms an outer ring surface and the attachment surface ( 12 ) forms an inner ring surface, and wherein the ring recess ( 38 ) which accommodates excess adhesives is provided between the contact surface ( 40 ) and the attachment surface ( 12 ).

2. A functional element ( 10 ) in accordance with claim 1 , wherein the adhesive ( 30 ) has the shape of a ring ( 30 ), one side ( 35 ) of which is designed for attachment to the functional element ( 10 ) and the second side ( 33 ) of which is designed for attachment to a plastic component.

3. A functional element ( 10 ) in accordance with claim 2 , wherein the adhesive ring ( 30 ) is realized as one of a transfer adhesive and a two-sided adhesive element.

4. A functional element ( 10 ) in accordance with claim 1 , wherein the adhesive is an adhesive which hardens under pressure.

5. A functional element ( 10 ) in accordance with claim 1 , wherein the adhesive is present in the form of an adhesive ring ( 30 ) with a rectangular cross-section.

6. A functional element ( 10 ) in accordance with claim 1 , wherein the adhesive ( 30 ) has at least one component present in at least one of micro-capsules and nano-capsules and adheres to the functional element at at least one of the attachment surface ( 12 ) and the centering section ( 16 ) by means of a bonding agent which holds the capsules together and to the functional element prior to the attachment to a component and prior to bursting of the micro-capsules or nano-capsules containing at least one component of the adhesive.

7. A functional element ( 10 ) in accordance with claim 1 , wherein the centering section ( 16 ) has a shape in cross section which is one of:
a round circular shape,
a ring shaped,
a polygonal shape,
a grooved shape and
a ribbed shape.

8. A functional element ( 10 ) in accordance with claim 1 , wherein it is one of the following elements:
a nut element,
a bolt element,
a hollow element,
an element having a cylindrical projection for receiving one of a shaft clip and a bearing sleeve.

9. A functional element ( 10 ) in accordance with claim 1 , wherein it is provided in conjunction with a plurality of like functional elements ( 10 ), with the functional elements being arranged in one row or in a plurality of rows in a flexible carrier band ( 31 ; 102 ) and being capable of being buttoned out of the carrier band by bending over of the carrier band.

10. A functional element ( 10 ) in accordance with claim 9 , wherein the carrier band ( 31 ) is formed at its surface confronting the functional elements ( 10 ) as a protective film for the adhesive or adhesive ring ( 30 ).
