Abstract

An elastic retaining member for fixing a timepiece component on a support element includes an opening into which the support element can be inserted, and rigid arms and elastic arms defined between connection areas of the member. The rigid arms and the elastic arms are configured to ensure elastic clamping of the support element in the opening, each of the rigid arms being provided with a single flat contact area and configured to cooperate with a corresponding convex contact portion of the support element.

First claim

The invention claimed is:

1. An elastic retaining member for fixing a timepiece component on a support element, comprising:
an opening configured to receive the support element; and
rigid arms and elastic arms defined between connection areas of the member, the rigid arms and the elastic arms being configured to ensure elastic clamping of the support element in the opening, and each of the rigid arms being provided with a single flat contact area and configured to cooperate with a corresponding convex contact portion of the support element, wherein
each of the elastic arms has a linear member with a first end connected to one of the rigid arms and a second end connected to another one of the rigid arms.

2. The elastic retaining member according to claim 1 , wherein the single flat contact area is distributed over an inner face of each of the rigid arms of the retaining member.

3. The elastic retaining member according to claim 1 , wherein the single flat contact area is defined on a convex inner face of each of the rigid arms of the retaining member, extending over all or part of a thickness of the retaining member.

4. The elastic retaining member according to claim 1 , wherein the single flat contact area is configured to cooperate with the corresponding contact portion of the support element and has a plano-convex-type contact configuration.

5. The elastic retaining member according to claim 1 , wherein the elastic retaining member comprises a contact area for each contact portion of the support element.

6. An elastic retaining member for fixing a timepiece component on a support element, comprising:
an opening configured to receive the support element; and
rigid arms and elastic arms defined between connection areas of the member, the rigid arms and the elastic arms being configured to ensure elastic clamping of the support element in the opening, and each of the rigid arms being provided with a single flat contact area and configured to cooperate with a corresponding convex contact portion of the support element,
wherein the elastic retaining member comprises a number of rigid arms equal to a number of elastic arms.

7. The elastic retaining member according to claim 1 , wherein the rigid arms and the elastic arms are arranged successively and alternately in the retaining member.

8. The elastic retaining member according to claim 1 , wherein each of the rigid arms has two opposing ends respectively connected to two different elastic arms.

9. The elastic retaining member according to claim 1 , wherein each of the rigid arms has a volume of material greater than a volume of material constituting each of the elastic arms.

10. The elastic retaining member according to claim 1 , wherein each of the elastic arms has a cross section which is smaller than a cross section of each of the rigid arms.

11. The elastic retaining member according to claim 1 , wherein each of the elastic arms has a body with a constant cross section.

12. The elastic retaining member according to claim 1 , wherein the elastic retaining member comprises a point of attachment with the timepiece component.

13. The elastic retaining member according to claim 1 , wherein the elastic retaining member is a collet for fixing the timepiece component to the support element.

14. The elastic retaining member according to claim 1 , wherein the elastic retaining member is made of a silicon-based material.

15. An elastic retaining member-timepiece component assembly for a horological movement of a timepiece comprising the retaining member according to claim 1 .

16. The assembly according to claim 15 , wherein the assembly is made in one piece.

17. An assemblage for horological movement of the timepiece comprising the elastic retaining member-timepiece component assembly according to claim 15 , wherein the assembly is fixed to the support element.

18. The horological movement comprising at least one assemblage according to claim 17 .

19. The timepiece comprising the horological movement according to claim 18 .

20. A method for assembling the elastic retaining member-timepiece component assembly with the support element according to claim 15 , comprising:
inserting the support element into the opening of the elastic retaining member of the assembly comprising elastically deforming the elastic retaining member provided with a phase of displacing the rigid arms of the elastic retaining member inducing a double elastic deformation of the elastic arms, and
fixing the retaining member on the support element comprising performing a radial elastic clamping of the retaining member on the support element.
