Abstract

A plastic component has a connecting element that includes an attachment portion protruding at least in part from the plastic component as well as an anchoring portion, by which the connecting element is releasably connected to the plastic component and which has a smaller cross-sectional diameter than the attachment portion.

First claim

What is claimed is:

1. A plastic component connection system, comprising:
a plastic component; and
a connecting element, the connecting element comprising:
an attachment portion which is of an at least partly spherical shape, where a portion of the at least partly spherical shape protrudes at least partly from the plastic component; and
an anchoring portion with which the connecting element is releasably joined to the plastic component, wherein

the anchoring portion includes a shaft, a clamping device, and a spherical bearing that is formed at an axial end of the shaft that faces the clamping device, wherein the clamping device is turned about the spherical bearing, and
the plastic component is a sandwich component with a core and at least one reinforcement layer, where the core is formed by foam material or wood.

2. The plastic component connection system according to claim 1 , wherein the clamping device is configured as a tensioner.

3. The plastic component connection system according to claim 2 , wherein the tensioner is a cam lever.

4. The plastic component connection system according to claim 1 , wherein:
the attachment portion protrudes from the plastic component on a first side of the plastic component and the anchoring portion protrudes at least partly on a second side of the plastic component, and
the first and the second side of the plastic component lie opposite each other.

5. The plastic component connection system according to claim 1 , wherein an opening is provided, which runs through the plastic component from a first side to a second side and into which at least the anchoring portion of the connecting element is inserted.

6. The plastic component connection system according to claim 5 , wherein:
the sandwich component comprises a core, with a first cover layer, forming the first side, and a second cover layer, forming the second side, and
the opening is configured as a round borehole, which has a first diameter in the area of the first cover layer and the core and a second diameter which is smaller than the first diameter in the area of the second cover layer, whereby the second cover layer forms an encircling collar in the axial direction of the opening, against which an insert abuts.

7. The plastic component connection system according to claim 1 , wherein the core is formed by polyurethane foam (PU foam), polyethylene foam (PET foam), polyvinyl chloride foam (PVC foam), polymethacrylimide foam (PMI foam), or polyether imide foam (PEI foam).

8. A plastic component connection system, comprising:
a plastic component; and
a connecting element, the connecting element comprising:
an attachment portion which is of an at least partly spherical shape, where a portion of the at least partly spherical shape protrudes at least partly from the plastic component; and
an anchoring portion with which the connecting element is releasably joined to the plastic component, wherein

the anchoring portion includes a shaft, a clamping device, and a spherical bearing that is formed at an axial end of the shaft that faces the clamping device, wherein the clamping device is turned about the spherical bearing, and
an insert resistant to compressive force is provided in an opening, by which a pretensioning force is transmittable between the attachment portion and the clamping device.

9. The plastic component connection system according to claim 8 , wherein:
the plastic component is a sandwich component which comprises a core, with a first cover layer, forming the first side, and a second cover layer, forming the second side, and
the opening is configured as a round borehole, which has a first diameter in the area of the first cover layer and the core and a second diameter which is smaller than the first diameter in the area of the second cover layer, whereby the second cover layer forms an encircling collar in the axial direction of the opening, against which the insert abuts.

10. The plastic component connection system according to claim 8 , wherein the insert is configured as a bushing with a flange.

11. The plastic component connection system according to claim 8 , wherein the clamping device is configured as a tensioner.

12. The plastic component connection system according to claim 11 , wherein the tensioner is a cam lever.
