Abstract

A monolithic component for a timepiece, in particular for a mechanical timepiece, comprising at least one rigid portion and an elastically flexible portion and designed to transmit the movement of an actuator of the timepiece to a driven part of the timepiece. The monolithic component comprises a rigid frame, a first rigid driving member, and a first elastically flexible structure connecting said frame to said first driving member. The first elastically flexible structure is configured in a manner such as to provide a displacement of said first driving member with at least two degrees of freedom, said displacement being caused as a result of the actuator coming into contact with said first driving member.

Claims

1. A monolithic component for a mechanical timepiece, designed to transmit the movement of an actuator of the timepiece to a driven part of the timepiece, said monolithic component comprising:

a rigid frame,

a first rigid driving member, and

a first elastically flexible structure connecting said frame to said first driving member,

wherein said first elastically flexible structure is configured in a manner such as to provide a displacement of said first driving member with at least two degrees of freedom, said displacement being caused under the effect of the actuator.

2. The monolithic component according to claim 1, wherein the displacement is caused as a result of a contact of the first driving member with the driven part.

3. The monolithic component according to claim 1, wherein the displacement is caused as a result of a contact of the first driving member with a supplementary guide element.

4. The monolithic component according to claim 1, wherein said actuator is an independent part which is adapted to come into contact with said monolithic component in order to cause said displacement.

5. The monolithic component according to claim 1, wherein said actuator is integral with said monolithic component.

6. The monolithic component according to claim 1, wherein the components of said displacement with at least two degrees of freedom are selected from translations, rotations, movements according to a remote centre of compliance (RCC) and combinations thereof.

7. The monolithic component according to claim 1, wherein said first elastically flexible structure comprises two flexible strips each extending between said frame and said first driving member.

8. The monolithic component according to claim 7, wherein points of contact of the two flexible strips with the first driving member are arranged in different zones of said first driving member.

9. The monolithic component according to claim 7, wherein one of the two said flexible strips comprises an elbowed portion which is angled substantially at a right angle.

10. The monolithic component according to claim 1, wherein an intermediate rigid portion is arranged between two flexible portions of said first elastically flexible structure.

11. The monolithic component according to claim 1, wherein said first elastically flexible structure comprises one or more flexible necks arranged between two rigid elements of said monolithic component.

12. The monolithic component according to claim 1, further comprising a second functional member and a second elastically flexible structure connecting said frame to said second functional member, said second elastically flexible structure being configured in a manner such as to place said second functional member in contact with a driven part.

13. The monolithic component according to claim 1, wherein said driven part is a date disc or ring, the actuator is a control wheel equipped with a driving finger, said rigid first driving member is a yoke connected to the rigid frame via a first elastically flexible structure comprising flexible strips, and said second functional member is a jumper connected to the rigid frame via a second elastically flexible structure in a manner such that said monolithic component acts as a driving member and securing member of a date disc or ring of a date mechanism of the respective timepiece.

14. The monolithic component according to claim 1, wherein said driven part is an automatic winding wheel, the actuator is an oscillating mass integral with the monolithic component, and said rigid driving member comprises two driving fingers which are each connected to the rigid frame via a first elastically flexible structure comprising flexible strips as well as rigid intermediate portions and which both act in alternation as the driving mechanism which is adapted to drive said automatic winding wheel, in a manner such that said monolithic component acts as a driving member for a winding wheel of an automatic winding mechanism of the respective timepiece.

15. A mechanical timepiece, comprising the monolithic component according to claim 1.
