Abstract

A remote control device for a horological movement of a watch wherein the remote control device includes an input control member intended to be acted on by a user and kinematically connected, with a connecting member, to an output control member intended to act on the horological movement of the watch, the connecting member being intended to be arranged such that it can rotate about the horological movement, and being configured such that it is driven in rotation by the input control member when the latter is acted upon, and such that it causes the output control member to move during this rotation.

First claim

The invention claimed is:

1. A remote control device for a horological movement of a watch comprising:
an input control member intended to be acted on by a user and kinematically connected, with a connecting member, to an output control member intended to act on the horological movement of said watch, the connecting member being intended to be arranged such that the connecting member can rotate about the horological movement, and to cause the output control member to move during said rotation,
wherein the input control member includes an engagement profile configured to engage with a driven engagement element of the connecting member, so as to drive said connecting member such that said connecting member rotates when said input control member is acted upon, the engagement profile and the driven engagement element being respectively shaped as complementary bevels,
wherein the output control member comprises an engagement profile configured to engage with a driving engagement element of the connecting member, such that the rotation of said connecting member causes said output control member to move, and
wherein the driven engagement element is disposed on a first portion of the connecting member and the driving engagement element is disposed on a second portion of the connecting member different than the first portion of the connecting member such that the driven engagement element and the driving engagement element both move with the connecting member when the connecting member rotates.

2. The control device according to claim 1 , comprising a support structure with which the input control member and output control member are integral, said support structure forming an annular recess receiving the connecting member.

3. The control device according to claim 1 , wherein the connecting member forms a ring.

4. The control device according to claim 1 , wherein the input control member is formed by a lever extending between a first end by which said lever is attached to the support structure such that said lever can rotate, at a first end, said lever including, at a second end, the engagement profile.

5. The control device according to claim 1 , comprising a support structure with which the input control member and output control member are integral, said support structure forming an annular recess receiving the connecting member, and wherein the input control member is arranged such that said input control member can slide relative to the support structure and is configured to engage, via the engagement profile, with a transmission element attached to the support structure such that said transmission element can rotate and engaging with the connecting member, such that the sliding of said input control member causes the connecting member to rotate.

6. The control device according to claim 2 , wherein the output control member is formed by a lever attached to the support structure such that said lever can rotate, at a first end, said lever including a bevel at a second end, constituting the engagement profile, said output control member being intended to act on the horological movement via an internal flank opposite the engagement profile.

7. The control device according to claim 2 , wherein the output control member is connected by a pivot link to the connecting member, and wherein said output control member is further connected to the support structure, said output control member comprising a bearing arm intended to be arranged such that said bearing arm bears against a balance of the horological movement in order to perform a balance stop function when the input control member is acted upon.

8. The control device according to claim 2 , wherein the driving engagement element is constituted by a catch.

9. The control device according to claim 1 , comprising a spring connected to the connecting member and biased to move said connecting member into a rest position wherein said connecting member is capable of engaging with the input control member.

10. The control device according to claim 1 , comprising a second input control member and a second output control member kinematically connected to one another via the connecting member and respectively configured to engage with another driven engagement member and with another driving engagement member, the input control members being configured such that, depending on which one is acted upon, the connecting member is driven in a different direction of rotation and causes one or the other output control member respectively to move.

11. The control device according to claim 10 , wherein the connecting member comprises a locking element arranged to constitute a banking preventing one of the input control members from making any movement when the other is acted upon.

12. The control device according to claim 10 , wherein the connecting member comprises a locking element arranged to constitute a banking preventing one of the input control members from making any movement when the other is acted upon and wherein the locking element is formed by a tooth extending between two bevelled radial flanks each constituting one of the driven engagement elements, the tooth further comprising an outer flank connecting the radial flanks together and being arranged so as to constitute the banking preventing one of the input control members from making any movement, when the other is acted upon.

13. A watch comprising:
a horological movement; and
the remote control device according to claim 1 .
