Abstract
Watch comprising a movement with an axially and rotationally movable main stem, and a control mechanism for the remote control of the main stem which comprises a secondary stem operable by a user and guided in rotation by guide means of a plate, and axial stop means for a secondary pinion integral in rotation with the secondary stem, and a transmission train meshed with the secondary pinion to transmit any rotation of the secondary pinion to the main stem, and further comprises an articulated connection, arranged to transmit any axial motion of the secondary stem to the main stem.
Claims11
A timepiece control mechanism for the remote control of an axially and rotationally movable main stem for operating a timepiece movement, said control mechanism comprising a secondary stem arranged to be operated by a user to control the motion of said main stem, and said control mechanism comprising a plate arranged to be secured to a said movement or to form a structural element of a said movement, which plate comprises means for guiding rotation of said secondary stem, and axial stop means for a secondary pinion with respect to which said secondary stem is free in translation and integral in rotation, said control mechanism comprising a transmission train meshed with said secondary pinion and arranged to transmit any rotation of said secondary pinion to said main stem, and further comprising an articulated connection, arranged to transmit any axial motion of said secondary stem to said main stem, wherein said articulated connection comprises at least, at a first end, a first lever pivoted on said plate and articulated to a second lever, also pivoted on said plate at a second end of said articulated connection, by an intermediate articulation or by other levers articulated to each other, said first lever being articulated at said first end with said main stem, and said second lever being articulated at said second end with said secondary stem.
A timepiece control mechanism for the remote control of an axially and rotationally movable main operating stem of a timepiece movement, said control mechanism comprising a secondary stem arranged to be operated by a user to control the motion of said main stem, said control mechanism comprising a plate arranged to be secured to a said movement or to form a structural element of a said movement, which plate comprises means for guiding rotation of said secondary stem, and axial stop means for a secondary pinion with respect to which said secondary stem is free in translation and integral in rotation, said control mechanism comprising a transmission train meshed with said secondary pinion and arranged to transmit any rotation of said secondary pinion to said main stem, and further comprising an articulated connection, arranged to transmit any axial motion of said secondary stem to said main stem, and said control mechanism comprising a main pinion arranged to be mounted freely in translation on said main stem and integral in rotation therewith, said transmission train being meshed with said main pinion, wherein said transmission train comprises at least one third intermediate wheel interposed between a first intermediate wheel arranged to cooperate with said main pinion and a second intermediate wheel arranged to cooperate with said secondary pinion.
