Abstract

A timepiece is equipped with a case that includes a case middle, a pusher, and a locking device for this pusher. The pusher is arranged movably in a translational manner in an actuation axis. The locking device contains a blocker that is movable in a translational manner along the actuation axis and with the ability to be displaced between a locking position and an unlocking position, in which positions the pusher is respectively to the locking and unlocking positions blocked and free in translation. The locking device contains in addition a control rotatably mounted in a general plane of the case between a first position and a second position corresponding respectively to the locking and unlocking positions for the blocker, this control containing structure for driving the blocker between its locking and unlocking positions.

First claim

What is claimed is:

1. A timepiece comprising:
a case;
a pusher mounted in a case middle of the case; and
a locking device adapted to lock the pusher,
the pusher being configured to undergo a translation along an axis of actuation of the pusher,
the locking device containing a blocking means and a control means arranged to control displacement of the blocking means between a locking position and an unlocking position, in which positions the pusher is respectively blocked and free in translation,
the control means extending in a general plane parallel to said actuation axis and being arranged movably in the general plane between a first position and a second position which correspond respectively to the locking and unlocking positions for the blocking means driven by the control means,
wherein said blocking means is arranged movably in a translational manner along the actuation axis and said blocking means is configured to be displaced by the control means along the actuation axis between said locking position, where the blocking means forms an axial abutment for the pusher, and said unlocking position set back from the locking position, the control means containing means for driving the blocking means in the actuation axis.

2. The timepiece according to claim 1 , wherein the driving means contains a cam for the radial positioning of the blocking means, the cam cooperating with a follower means that the blocking means contains.

3. The timepiece according to claim 2 , wherein the driving means contains an elastic return means configured to maintain the follower means in contact with the cam.

4. The timepiece according to claim 2 , wherein the cam exhibits a groove and the follower means is a pin inserted into the groove.

5. The timepiece according to claim 2 , wherein the cam is formed by a rib and the follower means is a slot.

6. The timepiece according to claim 1 , wherein the case contains or supports a bezel, wherein the control means is formed by a ring which is rotatably mounted between the case middle and the bezel about an axis that is perpendicular to said actuation axis.

7. The timepiece according to claim 1 , wherein the case contains or supports a bezel, wherein said control means is formed by the bezel which is rotatably arranged.

8. The timepiece according to claim 2 , wherein the blocking means is a cylindrical sleeve surrounding the pusher and configured to be displaced along said actuation axis of the pusher between said locking and unlocking positions.

9. The timepiece according to claim 2 , wherein the blocking means is a slider which is arranged slidably in said actuation axis of the pusher between said locking and unlocking positions.

10. The timepiece according to claim 1 , wherein the pusher contains a head and the blocking means is adapted to be positioned in order to lock the pusher bearing against the head.

11. The timepiece according to claim 1 , wherein the locking device contains a visual means facilitating the recognition of the position of the blocking means.

12. The timepiece according to claim 1 , wherein the locking device contains a means of positioning arranged in order to maintain the control means in one or other of the first and second positions.

13. The timepiece according to claim 1 , wherein, in the unlocked position, the blocking means is spaced apart from the pusher.

14. The timepiece according to claim 1 , wherein, in the locked position, the pusher extending outside of the case.

15. A timepiece comprising:
a case;
a pusher mounted in a case middle of the case; and
a locking device adapted to lock the pusher,
the pusher being configured to undergo a translation along an axis of actuation of the pusher by a user,
the locking device containing a cylindrical sleeve surrounding the pusher and a ring which is rotatably mounted between the case middle and the bezel,
the ring being arranged to control displacement of the cylindrical sleeve between a locking position and an unlocking position, in which positions the pusher is respectively blocked and free in translation,
the ring extending in a general plane parallel to said actuation axis and being arranged movably in the general plane between a first position and a second position which correspond respectively to the locking and unlocking positions for the cylindrical sleeve driven by the ring,
wherein said cylindrical sleeve is arranged movably in a translational manner along the actuation axis and said cylindrical sleeve is configured to be displaced by the ring along the actuation axis between said locking position, where the cylindrical sleeve forms an axial abutment for the pusher, and said unlocking position set back from the locking position, the ring containing a cam for driving the cylindrical sleeve in the actuation axis.

16. A timepiece comprising:
a case;
a pusher mounted in a case middle of the case; and
a locking device adapted to lock the pusher,
the pusher being configured to undergo a translation along an axis of actuation of the pusher by a user,
the locking device containing a slider surrounding the pusher and a bezel which is rotatably mounted,
the bezel being arranged to control displacement of the slider between a locking position and an unlocking position, in which positions the pusher is respectively blocked and free in translation,
the bezel extending in a general plane parallel to said actuation axis and being arranged movably in the general plane between a first position and a second position which correspond respectively to the locking and unlocking positions for the slider driven by the bezel,
wherein said slider is arranged movably in a translational manner along the actuation axis and said slider is configured to be displaced by the bezel along the actuation axis between said locking position, where the slider forms an axial abutment for the pusher, and said unlocking position set back from the locking position, the bezel containing a cam for driving the slider in the actuation axis.
