Abstract

A device ( 200; 200 ′) for selecting timepiece functions, including a setting lever device ( 150; 150 ′) and a frame ( 100; 100 ′), the setting lever device ( 150; 150 ′) comprising-including a setting lever ( 2; 2 ′) mounted movably on the frame ( 100; 100 ′) and a lever ( 3; 3 ′) mounted movably on the frame ( 100; 100 ′) or on the setting lever ( 2; 2 ′), the selection device ( 200; 200 ′) also including a first position indexing device ( 4; 4 ′) arranged so as to act on the setting lever ( 2; 2 ′), and a second position indexing device ( 5; 5 ′) arranged so as to act on the lever ( 3; 3 ″).

First claim

The invention claimed is:

1. A selection device for selecting timepiece functions, comprising:
a setting lever device, and
a frame,
the setting lever device comprising a setting lever mounted movably on the frame and a lever mounted movably on the frame or on the setting lever,
a first position indexing device arranged so as to act on the setting lever, and
a second position indexing device arranged so as to act on the lever,
wherein the selection device comprises a pawl member arranged so as to secure the setting lever and the lever.

2. The selection device as claimed in claim 1 , wherein the selection device comprises an interface element, and wherein the setting lever is engaged directly with the interface element.

3. The selection device as claimed in claim 2 , wherein the setting lever device, the first position indexing device, and the second position indexing device are arranged so that a stable position of the interface element is determined either by the first position indexing device or by the second position indexing device.

4. The selection device as claimed in claim 2 , wherein the interface element is a control stem, the setting lever being engaged directly with the control stem via a first setting lever stud fitted in a groove of the control stem.

5. The selection device as claimed in claim 1 , wherein the setting lever and the lever are pivoted about a same axis.

6. The selection device as claimed in claim 1 , wherein the pawl member is pivoted on the lever and arranged so as to cooperate with a second stud of the setting lever.

7. The selection device as claimed in claim 6 , wherein the selection device comprises an interface element, and wherein the setting lever is engaged directly with the interface element, and wherein the lever comprises an elongate cutout cooperating with the second stud of the setting lever, so as to kinematically connect the setting lever and the lever during a movement of the interface element.

8. The selection device as claimed claim 7 , wherein the pawl member is arranged so as to cooperate with the second stud through the elongate cutout formed in the lever.

9. The selection device as claimed in claim 1 , wherein the frame comprises a profile cooperating with the pawl member so as to at least partially control a position of the pawl member depending on a position of the setting lever, a position of the lever, or both a position of the setting lever and a position of the lever.

10. The selection device as claimed in claim 1 , wherein the first position indexing device comprises a first spring provided with a first functional surface and a third stud of the setting lever, the first functional surface and the setting lever cooperating by contact.

11. The selection device as claimed in claim 10 , wherein the first functional surface cooperates by contact with the third stud.

12. The selection device as claimed in claim 1 , wherein the second position indexing device comprises a second spring provided with a second functional surface and a mobile kinematically connected to the lever, the mobile comprising a third functional surface cooperating with the second functional surface.

13. The selection device as claimed in claim 12 , wherein the mobile is in meshing engagement with the lever.

14. The selection device as claimed in claim 1 , wherein the second position indexing device comprises a second spring provided with a second functional surface and a fourth stud of the lever, the second functional surface and the lever cooperating by contact.

15. The selection device as claimed in claim 14 , wherein the second functional surface and the lever cooperates by contact with the fourth stud.

16. A timepiece mechanism comprising a device for selecting timepiece functions as claimed in claim 1 .

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

18. A timepiece comprising the timepiece movement as claimed in claim 17 .

19. The selection device as claimed in claim 1 , wherein the setting lever device comprises the pawl member.

20. A selection device for selecting timepiece functions, comprising:
a setting lever device, and
a frame,
the setting lever device comprising a setting lever mounted movably on the frame and a lever mounted movably on the frame or on the setting lever,
a first position indexing device arranged so as to act on the setting lever, and
a second position indexing device arranged so as to act on the lever,
wherein the setting lever and the lever are pivoted about a same axis.

21. A selection device for selecting timepiece functions, comprising:
a setting lever device, and
a frame,
the setting lever device comprising a setting lever mounted movably on the frame and a lever mounted movably on the frame or on the setting lever,
a first position indexing device arranged so as to act on the setting lever, and
a second position indexing device arranged so as to act on the lever,
wherein the second position indexing device comprises a second spring provided with a second functional surface and a mobile kinematically connected to the lever, the mobile comprising a third functional surface cooperating with the second functional surface.

22. A selection device for selecting timepiece functions, comprising:
a setting lever device, and
a frame,
the setting lever device comprising a setting lever mounted movably on the frame and a lever mounted movably on the frame or on the setting lever,
a first position indexing device arranged so as to act on the setting lever, and
a second position indexing device arranged so as to act on the lever,
wherein the first position indexing device comprises a first spring provided with a first functional surface and a third stud of the setting lever, the first functional surface and the setting lever cooperating by contact, and
wherein the first functional surface cooperates by contact with the third stud.

23. A selection device for selecting timepiece functions, comprising:
a setting lever device, and
a frame,
the setting lever device comprising a setting lever mounted movably on the frame and a lever mounted movably on the frame or on the setting lever,
a first position indexing device arranged so as to act on the setting lever, and
a second position indexing device arranged so as to act on the lever,
