Abstract

Claims (29)

1. A timepiece mechanism for correcting a timepiece function, comprising:

a first lever comprising a first cam desmodromic connecting element,

a correcting mobile, and

a second lever,

the second lever comprising:

at least one first element for guiding the correcting mobile, wherein the at least one first element for guiding the correcting mobile comprises at least one guiding surface guiding the correcting mobile,

at least one first friction element in contact with the correcting mobile, wherein the at least one first friction element is located at the at least one guiding surface guiding the correcting mobile, and

a second cam desmodromic connecting element cooperating by contact with the first cam desmodromic connecting element.

2. The mechanism as claimed in claim 1 , wherein the first cam desmodromic connecting element is a stud and the second cam desmodromic connecting element is a cam profile, or wherein the first cam desmodromic connecting element is a cam profile and the second cam desmodromic connecting element is a stud.

3. The mechanism as claimed in claim 2 , wherein the cam profile is made up of a groove that is provided with at least two separate portions, or three separate portions.

4. The mechanism as claimed in claim 1 , wherein the second lever comprises at least one arm, and wherein the first friction element comprises at least one friction surface, the at least one arm being arranged so as to elastically return the at least one friction surface against the correcting mobile.

5. The mechanism as claimed in claim 1 , wherein the at least one first guiding element and the at least one first friction element are coincident or formed by one and the same element.

6. The mechanism as claimed in claim 1 , wherein the second lever is in one piece.

7. The mechanism as claimed in claim 1 , wherein the first lever and the second lever are configured and/or arranged so as to position the second lever in a first angular position and a second angular position about an axis of rotation of the second lever, the first angular position making it possible to activate a first corrective function, and the second angular position making it possible to deactivate the first corrective function.

8. The mechanism as claimed in claim 1 , wherein the first lever and the second lever are configured and/or arranged so as to allow the second lever to be positioned in a third angular position about its axis of rotation, making it possible to activate a second corrective function.

9. The mechanism as claimed in claim 8 , wherein the first lever and the second lever are configured and/or arranged so that, in the second angular position, the second corrective function is deactivated.

10. The mechanism as claimed in claim 1 , wherein the mechanism comprises a selection device comprising a setting lever device including a setting lever and a third lever, and wherein the first lever is controlled by the selection device, the setting lever device and the first lever being configured and/or arranged so that the first lever is positioned (i) by the setting lever or (ii) by a profile of a control mobile kinematically connected to the third lever.

11. The mechanism as claimed in claim 10 , wherein the mechanism comprises an interface element, and wherein the mechanism is arranged so that, when the selection device is configured in a first configuration corresponding to a first axial position of the interface element, the second lever is in the second angular position, in which the first and second corrective functions are deactivated.

12. The mechanism as claimed in claim 11 , wherein the mechanism comprises an interface element, and wherein the mechanism is arranged so that, when the selection device is configured in a second configuration, corresponding to a second axial position of the interface element, the second lever features the first angular position, in which the first corrective function is activated.

13. The mechanism as claimed in claim 10 , wherein the mechanism comprises an interface element, and wherein the mechanism is arranged so that, when the selection device is configured in a third configuration, corresponding to the second axial position of the interface element, the second lever is able to feature a third angular position, in which the second corrective function is activated.

14. The mechanism as claimed in claim 10 , wherein the mechanism comprises an interface element, and wherein the mechanism is arranged so that, when the selection device is configured in a fourth configuration, corresponding to a third axial position of the interface element, the second lever is in the second angular position, in which the first and second corrective functions are deactivated.

15. A timepiece movement comprising the timepiece mechanism as claimed in claim 1 .

16. A timepiece comprising the timepiece movement as claimed in claim 15 .

17. The timepiece mechanism as claimed in claim 1 , wherein the at least one first element for guiding the correcting mobile is for guiding the correcting mobile in rotation about an axis that is fixed regarding the second lever.

18. The mechanism as claimed in claim 1 , wherein the second lever has a thickness less than 200 μm.

19. The mechanism as claimed in claim 7 , wherein the first corrective function is a corrective function for the indication of the date.

20. The mechanism as claimed in claim 8 , wherein the second corrective function is a corrective function for the indication of the day.

21. The mechanism as claimed in claim 1 , wherein the correcting mobile is pivoted on the second lever.

22. The mechanism as claimed in claim 6 , wherein the correcting mobile is pivoted on the second lever.
