Patent ID: 8439558

Claim:
A winding and time-setting control device for a timepiece movement, wherein the timepiece movement includes (i) a movement stem that rotates about an axis in a movement plate; (ii) a sliding pinion, wherein the movement stem is secured in rotation to the sliding pinion; and (iii) a sliding pinion lever, wherein the sliding pinion is axially movable via an action of the sliding pinion lever along the axis in the movement plate, wherein the sliding pinion lever is movable between a winding position and a time-setting position, wherein while in the winding position, the sliding pinion is arranged so as to cooperate with a winding mechanism to set the winding mechanism in rotation, wherein while in the time-setting position, the sliding pinion is arranged so as to cooperate with a time-setting mechanism to set the time-setting mechanism in rotation, the winding and time-setting control device comprising: (a) a control stem, wherein the control stem is connected in rotation to the movement stem by a transmission means and shifted relative to the movement stem, wherein the control stem rotates about a longitudinal axis and is axially slidable at least between a winding control position and a time-setting control position; (b) a manual control crown, wherein the control stem is arranged for cooperating with the manual control crown; and (c) a first pull-out mechanism, wherein the sliding pinion lever is part of the first pull-out mechanism, and wherein the first pull-out mechanism is actuated by sliding the control stem between the winding control position and the time-setting control position, wherein the sliding pinion meshes with the winding mechanism in the winding position when the control stem is in the winding control position, or with the time-setting mechanism when the control stem is in the time-setting control position, wherein the first pull-out mechanism includes (i) a first lever, wherein the first lever is formed by a first pull-out piece that has a first pull-out piece arm and a first pivot; (ii) a first pivoting axis, wherein the first pivoting axis has a first side and a second side, and wherein the first pull-out piece arm moves in translation via the effect of a translation of the control stem, and wherein the first pull-out piece arm moves either on the first side of the second side of the first pivoting axis; (iii) a second lever, wherein the second lever is formed by a second pull-out piece that has a second pull-out piece arm and a second pivot, wherein the second pull-out arm is movable inside a housing that includes the movement stem, and wherein the second pull-out piece drives the sliding pinion lever to move the sliding pinion; (iv) a second pivoting axis; and (v) a third pivoting axis, wherein the first pivot cooperates, along the third pivoting axis, with the second pivot.
