摘要:
The invention concerns a winding and time-setting control device (100) for a timepiece movement including, connected in rotation, a movement stem (2) secured in rotation to a sliding pinion (8) driven in translation by a lever (52) between winding and time-setting positions, and a control stem (1) sliding between winding and time-setting control positions, actuating a pull-out mechanism (6). It is characterized in that the mechanism (6) includes a first pull-out piece (40) including, about a first axis (A1), an arm (40A) movable with the control stem (1), and a pivot (40B) cooperating with a complementary pivot (60B) of a second pull-out piece (60) driving the lever (52) and including an arm (60A) movable inside a housing (61) in the movement stem (2). The invention also concerns a timepiece incorporating a device (100) of this type.

The musical or striking watch includes a watch case, which is formed of a middle part and a back cover, provided with side apertures and removably secured in a sealed manner to the middle part. A crystal closes the case in a sealed manner. A timepiece movement is held inside the watch case and provided with a striking mechanism that can be actuated at determined times to produce notes or music. The watch further includes at least one removable acoustic radiating membrane, which is arranged in the watch case. The removable membrane includes, in a central position, a retaining member. This retaining member is arranged with play in a housing in an inner stop member of the back cover. Owing to the cooperation between the retaining member and the stop member, the bending of the membrane is limited following excess pressure or vacuum pressure according to environmental conditions.

The control stem device for a watch includes a first stem (1) rotating about its longitudinal axis and provided with means (32) for securing it to a manual control crown on the exterior of the watch, and a second stem (2), substantially parallel and shifted in relation to said first stem and secured to an axially mobile sliding pinion (8) for selectively driving in rotation a mechanism for a first function (20) and a mechanism for a second function (242), the first and second stems being connected in rotation by a transmission device (5). The first stem is mounted to be axially mobile at least between an operating position associated with said first function and an operating position associated with said second function, so as to activate, by sliding between said positions, a pull-out mechanism (6) which cooperates with said sliding pinion (8) to make said pinion pass from one axial position to another, said sliding pinion (8) being meshed with the mechanism for the first function in one of its positions and with the mechanism for the second function in the other position. The first stem (1) slides in the first pinion (35) of the gear and can be removed. This device allows the control crown to be placed half way up the watchcase, in particular in the case of a watch with complications having a very thick movement.
摘要:
A timepiece wheel governor for regulating the pivoting speed (ω) of a wheel set, about a pivot axis, including a pivoting inertia-block. It includes a spring to return this block towards this axis, and, when the wheel set pivots at a lower speed than a reference speed (ωc), this block remains confined within a first volume of revolution, and, when the wheel set pivots at a higher speed than the reference speed (ωc), this block is engaged, in one peripheral portion thereof, in a second volume contiguous with and external to the first one, this peripheral portion cooperating in this second volume with a regulator arranged to brake the wheel set and return the pivoting speed (ω) thereof to the reference speed (ωc), and to dissipate the surplus energy.

Timepiece wheel governor (1) for regulating the pivoting speed (ω) of a wheel set (3), about a pivot axis (D1), including a pivoting inertia-block (4).It includes a means (7) of returning said block (4) towards said axis (D1), and, when said wheel set (3) pivots at a lower speed than a reference speed (ωc), said block (4) remains confined within a first volume of revolution (VI), and, when said wheel set (3) pivots at a higher speed than said reference speed (ωc), said block (4) is engaged, in one peripheral portion (30) thereof, in a second volume (VE) contiguous with and external to said first one (VI), said peripheral portion (30) cooperating in said second volume (VE) with a regulating means arranged to brake said wheel set (3) and return the pivoting speed (ω) thereof to said reference speed (ωc), and to dissipate the surplus energy.

The timepiece movement (1) includes a karussel (4) whose platform carries an escape wheel that cooperates with a balance (7). The platform is driven from the time display mechanism associated with a time-setting mechanism (32). The escape wheel is driven directly from the gear train. In addition to compensating for differences in rate due to gravity, the karussel of the invention proposes a new, complementary role: that of time indicator.
