Abstract

A watch case having a locking system for at least one control element of a timepiece, the locking system including a manipulable element, a locking element for the at least one control element, and a kinematic link linking the manipulable element to the locking element, the locking system being arranged on the outside of a chamber ( 63 ), more particularly on the outside of a water-resistant chamber, defined by the case, the locking element being rotatably mounted, more particularly rotatably mounted about a second axis (A 1 ) of the at least one control element.

First claim

The invention claimed is:

1. A watch case comprising a locking system for at least one control element of a timepiece, the locking system comprising:
a manipulable element,
a locking element for the at least one control element, and
a kinematic link linking the manipulable element to the locking element,
wherein the locking system is arranged on the outside of a chamber defined by the case, and
wherein the locking element is rotatably mounted relative to the case middle about an axis of the at least one control element.

2. The watch case as claimed in claim 1 , wherein the locking system comprises an element for displaying the state of locking of the at least one control element.

3. The watch case as claimed in claim 2 , wherein the element for displaying the state of locking of the at least one control element is a display element formed on the locking element or in a kinematic link with the locking element.

4. The watch case as claimed in claim 1 , wherein the kinematic link comprises a toothing on the manipulable element and/or a toothing on the locking element.

5. The watch case as claimed in claim 1 , wherein the at least one control element comprises at least one push-button and/or at least one crown.

6. The watch case as claimed in claim 1 , wherein the manipulable element is rotatably mounted or is movably mounted in translation.

7. The watch case as claimed in claim 6 , wherein the manipulable element is rotatably mounted relative to a first axis perpendicular or substantially perpendicular to a second axis of the at least one control element.

8. The watch case as claimed in claim 6 , wherein the manipulable element is rotatably mounted relative to a first axis parallel or substantially parallel to a second axis of the at least one control element.

9. The watch case as claimed in claim 1 , wherein the manipulable element comprises a ring and/or a bezel.

10. The watch case as claimed in claim 1 , wherein the watch case comprises a bezel, and wherein the manipulable element comprises a ring movably mounted relative to the bezel.

11. The watch case as claimed in claim 10 , wherein the ring is movably mounted in rotation about the bezel.

12. The watch case as claimed in claim 1 , wherein the manipulable element is movably mounted in translation in a third axis perpendicular or substantially perpendicular to a second axis of the at least one control element.

13. The watch case as claimed in claim 1 , wherein the locking element comprises an abutment preventing or limiting the displacement of the at least one control element and/or confining the control element in a first locked position.

14. The watch case as claimed in claim 13 , wherein the abutment is arranged in such a way as to prevent or limit the displacement in translation of the at least one control element.

15. The watch case as claimed in claim 1 , wherein the manipulable element is mobile between a first locking position of the at least one control element and a second unlocking position of the at least one control element.

16. The watch case as claimed in claim 15 , wherein the manipulable element is adapted to be placed in a third position between the first locking and second unlocking positions, in which at least one control element is locked and at least one control element is unlocked.

17. A timepiece comprising a watch case as claimed in claim 1 .

18. The watch case as claimed in claim 1 , wherein the chamber is a water-resistant chamber.

19. The watch case as claimed in claim 18 , wherein the locking element is rotatably mounted about a second axis of the at least one control element.
