Abstract

An elastic connecting block with which, by receiving a connecting pin, at least two components can be connected together via a respective component opening. The connecting block, which is formed as a single piece, comprises a central bearing block with two mutually opposing bearing surfaces for the components to be connected. A locking flange, which can be engaged in a component opening, is provided on the first bearing surface. On the other bearing surface, a widening flange is provided, which can be expanded by a spherical head of the connecting pin such that the widening flange is held via an axial undercut in the second component opening of the second component.

First claim

The invention claimed is:

1. An elastic connecting block with which, through a receiving of a connecting pin, at least two components are connectable with each other via one component opening each, and which includes the following features:
a. a central abutment block being formed as one piece, which includes a first and a second abutment surface being arranged opposite each other and running parallel with respect to each other, in which
b. the first abutment surface comprises a tube-shaped locking flange which extends perpendicularly with regard to the first abutment surface, includes a first central passage channel and includes a circumferential locking recess in combination with a locking web at a radial outside, and
c. the second abutment surface includes a tube-shaped widening flange without an outer locking structure which extends perpendicularly to the second abutment surface and includes a second central passage channel which tapers in the direction facing away from the second abutment surface, and
d. a central fastening channel completely passes through the abutment block, ends in the first and the second central passage channel and includes a radially widened damping space between the first and the second abutment surface, wherein the damping space opens radially beyond an inner diameter of the first and the second passage channel so that the damping space is spaced away from the first and the second abutment surface and is not integrated in the fastening channel but extends beyond the fastening channel in the radial direction with respect to a longitudinal axis of the fastening channel.

2. The elastic connecting block according to claim 1 , in which the damping space is configured spherically shaped, so that a spherical section of the connecting pin is releasably lockable in there.

3. The elastic connecting block according to claim 2 , in which the locking flange and the widening flange comprise lead-in chamfers which are arranged at a radial outside.

4. The elastic connecting block according to claim 2 , in which at the locking flange, the locking web is configured circumferentially all round and wavelike in the radial cross section in order to guarantee an elastic deforming of the locking flange in the radial direction and in the axial direction.

5. The elastic connecting block according to claim 2 , in which the abutment block has a cylindrical form in which the passage channel is arranged concentrically with respect to an axis of symmetry of the abutment block.

6. The elastic connecting block according to claim 1 , in which the locking flange and the widening flange comprise lead-in chamfers which are arranged at a radial outside.

7. The elastic connecting block according to claim 6 , in which at the locking flange, the locking web is configured circumferentially all round and wavelike in the radial cross section in order to guarantee an elastic deforming of the locking flange in the radial direction and in the axial direction.

8. The elastic connecting block according to claim 6 , in which the abutment block has a cylindrical form in which the passage channel is arranged concentrically with respect to an axis of symmetry of the abutment block.

9. The elastic connecting block according to claim 1 , in which at the locking flange, the locking web is configured circumferentially all round and wavelike in the radial cross section in order to guarantee an elastic deforming of the locking flange in the radial direction and in the axial direction.

10. The elastic connecting block according to claim 1 in which the abutment block has a cylindrical form in which the passage channel is arranged concentrically with respect to an axis of symmetry of the abutment block.

11. The elastic connecting block according to claim 10 , in which the abutment block has wavelike punctures at a radial outside which form a wave spring structure.

12. The elastic connecting block according to claim 10 , in which the abutment block has radially and/or axially extending openings and/or punctures at a radial outside.

13. The elastic connecting block according to claim 10 , in which the abutment block consists of a solid material or of a foamed material with air pockets.

14. A connecting pin with which a connection between at least a first component with a first component opening and a second component with a second component opening can be established with the help of a connecting block according to claim 1 arranged in between, and which includes the following features:
a. an end collar at a first axial end of the connecting pin,
b. a first cylinder section, directly following the end collar and running in axial direction, having a smaller outer diameter than the end collar,
c. a second cylinder section directly following the first cylinder section, having a smaller outer diameter than the first cylinder section, and
d. a thickened end section at a second axial end of the connecting pin extending radially beyond the first cylinder section, and
e. the thickened end section is connected with a third cylinder section, which faces the second cylinder section axially.

15. A connection between a first component with a first component opening and a second component with a second component opening via an elastic connecting block according to claim 1 and a connecting pin according to claim 14 arranged in there.

16. The connecting pin according to claim 14 , in which the first and the second cylinder section are directly connected with each other via a truncated cone section.

17. The connecting pin according to claim 16 , in which the thickened end section is spherically shaped or semi-spherically shaped or elliptic or in the form of an arrow tip.

18. The connecting pin according to claim 14 , in which the thickened end section is spherically shaped or semi-spherically shaped or elliptic or in the form of an arrow tip.
