Movement for timepiece and timepiece
The present invention relates to a watch-movement comprising a counting assembly comprising a first energy source and a gear train kinematically connected to at least one time indicator; and a regulating assembly comprising a regulating organ. This watch-movement is characterised in that it further comprises a locking member for the gear train; a mobile assembly carrying the regulating assembly; a guiding assembly for the mobile assembly comprising at least one rail; a drive mechanism for the mobile assembly arranged to move this mobile assembly along the guiding assembly; and a release mechanism for the locking member. The invention also relates to a watch comprising such a watch-movement.
1 . Watch movement comprising:
a counting assembly comprising a first energy source and a gear train kinematically connected to at least one time indicator, this counting assembly forming part of a first kinematic chain; and
a regulating assembly comprising a regulating organ and forming part of a second kinematic chain different from the first kinematic chain;
said watch movement further comprises
a locking member for said gear train, said locking member forming part of said first kinematic chain and being arranged to connect or disconnect said first kinematic chain and said second kinematic chain when said locking member is actuated;
a mobile assembly carrying said regulating assembly;
a guiding assembly for the mobile assembly, comprising at least one rail;
a drive mechanism for the mobile assembly arranged to move this mobile assembly along the guide assembly; and
a release mechanism for releasing the locking member.
2 . Watch-movement according to claim 1 , wherein the guiding assembly comprises at least one driving rail provided with a rack.
3 . Watch movement according to claim 2 , wherein the mobile assembly comprises at least one carriage holding said mobile assembly between said driving rail and at least one guide rail.
4 . Watch movement according to claim 2 , wherein the drive mechanism of the mobile assembly comprises a driving wheel meshing with the rack of the driving rail, this driving wheel being kinematically linked to the regulating organ.
5 . Watch movement according to claim 1 , wherein the guiding assembly comprises at least one guide rail.
6 . Watch movement according to claim 1 , wherein the release mechanism comprises a mobile part carried by the mobile assembly and a pivoting part carried by a plate of the watch movement.
7 . Watch movement according to claim 6 , wherein the pivoting part of the release mechanism comprises a whip pivoting about a whip axis integral with a plate, and a clearance arm.
8 . Watch movement according to claim 7 , wherein the whip comprises a ramp arranged to cause the whip to pivot about the whip axis when the mobile part of the release mechanism acts on the ramp.
9 . Watch movement according to claim 8 , wherein the mobile part of the release mechanism comprises a release arm arranged to actuate the ramp of the pivoting part of the release mechanism during the displacement of the mobile assembly along the guiding assembly.
10 . Watch movement according to claim 6 , wherein the locking part of the release mechanism comprises a lever acting on a transfer gear and actuated by a clearance arm.
11 . Watch movement according to claim 1 , wherein the counting assembly comprises at least one transmission gear kinematically connected to the first energy source and in that the locking member acts on the transmission gear.
12 . Watch movement according to claim 1 , wherein the regulating assembly comprises a second energy source.
13 . Watch movement according to claim 12 , wherein the second energy source comprises a spiral spring kinematically connected to a paddle wheel.
14 . Watch movement according to claim 12 , wherein the watch movement comprises at least two energy transmission mechanisms arranged to transmit energy from the first energy source to the second energy source.
15 . Watch comprising a watch-movement according to claim 1 .
