Abstract

An elastic holding organ for fastening a timepiece component on a support element, including a rigid portion provided with an inner face including at least three deformable arms provided with free ends defining an opening into which the support element can be inserted, the arms being configured to perform a coupling with the support element by an elastic clamping in compression of this support element in the opening.

First claim

The invention claimed is:

1. An elastic holding organ for fastening a timepiece component on a support element, comprising:
a rigid portion comprising an inner face comprising at least three deformable arms provided with free ends defining an opening into which said support element can be inserted, the arms being configured to perform a coupling with the support element by an elastic clamping in compression of said support element in the opening, wherein each deformable arm comprises a main part comprising a material volume which regularly decreases from a direction from said inner face towards a central axis of said organ.

2. The organ according to claim 1 , wherein the rigid portion comprises a material volume which is greater than the sum of the material volumes of the deformable arms of said holding organ.

3. The organ according to claim 1 , wherein each arm has an essentially trapezoidal shape.

4. The organ according to claim 1 , wherein the inner face defines a volume in said organ partially occupied by the deformable arms.

5. The organ according to claim 1 , comprising six deformable arms.

6. The organ according to claim 1 , wherein the organ is made of a fragile material.

7. The organ according to claim 1 , wherein the organ is a collet.

8. A set for a horological movement of a timepiece comprising:
the organ according to claim 1 , and
the timepiece component.

9. An assembly comprising:
the set according to claim 8 , and a support element, said set being coupled by an elastic clamping in compression with the support element.

10. The horological movement comprising at least one of the assembly according to claim 9 .

11. The timepiece comprising the horological movement according to claim 10 .

12. The organ according to claim 1 , wherein two of the arms join at the free end to form a common contact face.

13. The organ according to claim 12 , wherein an internal opening is positioned between the two of the arms that join at the free end to form the common contact face, and the internal opening does not extend to the opening.

14. The organ according to claim 1 , wherein the organ is made of a micromachinable material.

15. The organ according to claim 1 , wherein the organ comprises silicon, quartz, corundum, silicon and silicon dioxide, metallic glass, ceramic, or an at least partially amorphous material.
