Abstract

A detachable connecting device for connecting first and second functional components to each other has a connecting element arranged in a connecting element receptacle of the first functional component so as to be force-transmitting. A bushing that is circumferentially closed is arranged on the connecting element. A bushing receptacle is provided on the second functional component. The bushing together with the connecting element is arranged in the bushing receptacle for realizing force transmission between connecting element and second functional component. The bushing receptacle has a circumferential side relative to the connecting axis that is provided with an insertion section with insertion opening to insert the bushing from outside of the circumferential side into the interior of the bushing receptacle or to remove the bushing from the interior of the bushing receptacle through the circumferential side.

First claim

What is claimed is:

1. A detachable connecting device for connecting a first functional component and a second functional component to each other, the connecting device comprising:
at least one connecting element adapted to be arranged by a rotary and/or plug-in movement relative to an imaginary connecting axis of the connecting device in at least one connecting element receptacle of the first functional component so as to be force-transmitting;
at least one bushing that, relative to the connecting axis, is circumferentially closed and adapted to be arranged on the at least one connecting element;
at least one bushing receptacle provided on the second functional component;
wherein the at least one bushing together with the at least one connecting element is adapted to be arranged in the at least one bushing receptacle for realizing a force transmission between the at least one connecting element and the second functional component;
wherein the at least one bushing receptacle comprises a circumferential side relative to the connecting axis, wherein the circumferential side comprises an insertion section with an insertion opening for insertion of the at least one bushing into the at least one bushing receptacle from outside of the circumferential side into an interior of the at least one bushing receptacle or for removal of the at least one bushing from the interior of the at least one bushing receptacle through the circumferential side;
wherein the at least one bushing receptacle comprises a radial inner circumferential side, relative to the connecting axis, and the radial inner circumferential side widens toward the connecting element receptacle, when viewed in axial direction;
wherein the radial inner circumferential side widens conically.

2. The connecting device according to claim 1 , wherein
at least the insertion section of the at least one bushing receptacle is at least partially elastic at least in a direction transverse to the connecting axis.

3. The connecting device according to claim 1 , wherein
at least the at least one bushing receptacle comprises plastic material.

4. The connecting device according to claim 1 , wherein
the at least one bushing comprises a radial outer circumferential side provided with at least one projection,
wherein the radial inner circumferential side comprises an end face rim, facing the at least one connecting element receptacle and provided with at least one widened section for receiving the at least one projection of the radial outer circumferential side of the at least one bushing.

5. A detachable connecting device for connecting a first functional component and a second functional component to each other, the connecting device comprising:
at least one connecting element adapted to be arranged by a rotary and/or plug-in movement relative to an imaginary connecting axis of the connecting device in at least one connecting element receptacle of the first functional component so as to be force-transmitting;
at least one bushing that, relative to the connecting axis, is circumferentially closed and adapted to be arranged on the at least one connecting element;
at least one bushing receptacle provided on the second functional component;
wherein the at least one bushing together with the at least one connecting element is adapted to be arranged in the at least one bushing receptacle for realizing a force transmission between the at least one connecting element and the second functional component;
wherein the at least one bushing receptacle comprises a circumferential side relative to the connecting axis, wherein the circumferential side comprises an insertion section with an insertion opening for insertion of the at least one bushing into the at least one bushing receptacle from outside of the circumferential side into an interior of the at least one bushing receptacle or for removal of the at least one bushing from the interior of the at least one bushing receptacle through the circumferential side;
wherein the at least one bushing receptacle comprises a radial inner circumferential side, relative to the connecting axis, and the radial inner circumferential side widens toward the connecting element receptacle, when viewed in axial direction;
wherein the at least one bushing comprises a radial outer circumferential side provided with at least one projection,
wherein the radial inner circumferential side comprises an end face rim, facing the at least one connecting element receptacle and provided with at least one widened section for receiving the at least one projection of the radial outer circumferential side of the at least one bushing.

6. The connecting device according to claim 5 , wherein
the at least one bushing receptacle comprises an approximately U-shaped inner profile in a radial cross-section relative to the connecting axis.

7. The connecting device according to claim 5 , wherein
the insertion opening has an inner width at least in a clamping area of the at least one bushing receptacle, viewed in a circumferential direction relative to the connecting axis,
wherein the inner width is smaller than an outer diameter of the at least one bushing at least in a section of the at least one bushing that, when the bushing is mounted in the at least one bushing receptacle, is located axially at a level of the clamping area relative to the connecting axis.

8. The connecting device according to claim 5 , wherein
the at least one bushing receptacle comprises a transition from the insertion section into a receiving section in the interior of the at least one bushing receptacle,
wherein the transition comprises an undercut.

9. The connecting device according to claim 8 , wherein
the receiving section is a clamping area of the bushing receptacle.

10. The connecting device according to claim 5 , wherein
at least the at least one bushing receptacle is comprised of plastic material.

11. The connecting device according to claim 5 , wherein
the radial inner circumferential side widens conically.

12. A functional component comprising:
at least one part of a detachable connecting device for connecting said functional component to at least one other functional component, wherein the connecting device comprises at least one connecting element that is adapted to be arranged by a rotary and/or plug-in movement relative to an imaginary connecting axis of the connecting device in at least one connecting element receptacle of the at least one other functional component so as to be force-transmitting;
wherein the at least one part of the detachable connecting device is a bushing receptacle adapted to receive a bushing of the connecting device for realizing a force transmission between the at least one connecting element and said functional component, wherein the bushing is circumferentially closed relative to the connecting axis and adapted to receive the at least one connecting element;
wherein the bushing receptacle comprises a circumferential side relative to the connecting axis and the circumferential side comprises an insertion section with an insertion opening for insertion of the bushing into an interior of the bushing receptacle from outside of the circumferential side or for removal of the bushing from the interior of the bushing receptacle through the circumferential side;
wherein the at least one bushing receptacle comprises a radial inner circumferential side, relative to the connecting axis, and the radial inner circumferential side widens toward the connecting element receptacle, when viewed in axial direction;
wherein the radial inner circumferential side widens conically.
