Hollow-cylindrical base element of a connecting unit
A hollow-cylindrical base element of a connecting unit for connecting a first component to a second component with a distance therebetween has an outer side, a threadless inner side, adjacent to a first axial end has a first drive feature and a first inner diameter, and adjacent to a second axial end a pivoting element with a threadless passage opening having a second inner diameter smaller than the first inner diameter. A first outer thread is provided between the first and the second axial end, wherein the first outer thread, when used in the first component, is in engagement therewith. The pivoting element is at least partially in engagement with the inner side of the base element in such a form-fitting manner that it is immovable along a longitudinal axis of the base element and is pivotable relative to the base element.
1 . A hollow-cylindrical base element of a connecting unit for connecting a first component to a second component with a distance therebetween, comprising:
a. an outer side and a threadless inner side,
b. adjacent to a first axial end, a first drive feature and a first inner diameter,
c. between the first axial end and a second axial end arranged opposite to the first axial end and following a flange at the first axial end, a first outer thread which, when used in the first component, is in engagement therewith, wherein
d. a section with the first inner diameter transitions with a step into a connecting section terminating with the second axial end so that the connecting section is present between the step and the second axial end, and the hollow-cylindrical base element further comprises:
e. a pivoting element comprising a ball segment section as well as a cylindrical section and having a threadless passage opening which has a second inner diameter which is smaller than the first inner diameter, wherein the cylindrical section is arranged at the ball segment section facing away from the first axial end such that, when in use, the cylindrical section provides an abutment face for the second component, wherein,
f. the pivoting element is provided adjacent to the second axial and the connecting section is adapted to the ball segment section so that the pivoting element is in engagement at least partially with the threadless inner side of the hollow-cylindrical base element in the area of the connecting section and in such a form-fitting manner that it
f1. is immovable in either axial direction along a longitudinal axis of the base element so that the pivoting element cannot be released from the base element without destroying the base element,
f2. is non-detachably connected to the base element along the longitudinal axis, and
f3. is pivotable relative to the longitudinal axis of the base element, and
g1. the pivoting element is circumferentially completely surrounded by the base element or
g2. the base element comprises a radial cutout or clearance adjacent to the second axial end which is dimensioned such that the pivoting element can be clipped in laterally relative to the longitudinal axis of the base element.
2 . The hollow-cylindrical base element according to claim 1 in which the first outer thread is formed in a self-cutting or self-tapping manner.
3 . The hollow-cylindrical base element according to claim 1 , which comprises, adjacent to the second axial end, a circumferential groove for the fastening of a securing disc.
4 . The hollow-cylindrical base element according to claim 1 , wherein the base element is made of a first plastic and the pivoting element is made of a second plastic or metal.
5 . The hollow-cylindrical base element according to claim 1 , in which the pivoting element is pivotable by a solid angle of at least 2° relative to the longitudinal axis of the base element.
6 . The hollow-cylindrical base element according to claim 1 , wherein the pivoting element can be rotated by 360° relative to the base element.
7 . A connection of a first and a second component with a distance therebetween, wherein
a hollow-cylindrical base element according to claim 1 is screwed into the first component and
a second outer thread of a connecting screw is in engagement with a second inner thread at or adjacent to the second component, wherein
the connecting screw has a head and a shaft and the second outer thread is provided at the shaft, which is, in use, in engagement with the second inner thread at or adjacent to the second component, wherein the first inner diameter of the base element is larger than an outer diameter of the head of the connecting screw and the second inner diameter of the passage opening of the pivoting element is larger than an outer diameter of the shaft of the connecting screw, so that the head of the connecting screw is arrangeable in the base element and the shaft of the connecting screw extends through the passage opening.
