  • Publication number: 20220206435
    Abstract: A timepiece incudes a crown (4) housed in a cavity (10) provided in the case and open towards the outside, such as a cavity (10) in the side wall of the case (1) of a wristwatch, in the rest position of the crown (4). To bring the crown out of its rest position, the user rotates a rotary knurling-roller (5). The knurling-roller (5) is coupled to a tube (15) wherein is inserted a crown body (18) integral with the crown. The rotation of the knurling-roller actuates rotation as well as translation of the tube, which is linked only in translation to said cylinder (18). The tube displaces the crown in an axial direction without rotating the crown around its central axis (6). At least one control position of the crown and the rod can be reached, by rotating the knurling-roller (5) without having to manually pull the crown outwards.

  • Publication number: 20220163921
    Abstract: The present invention relates to a crown-push-button (3) provided with a spring (10) disposed within a cage (11) integral in rotation with the movement of the head (4) of the crown-push-button (3), the spring (10) being arranged within the cage (11) so as to be rotated with the cage. The base (13c) of the spring cage is provided with cells (18) cooperating with protuberances (17) formed in a washer (14) disposed on the seat (6a) of the tube (6) of the crown-push-button, the rotation of the crown-push-button being then accompanied by a click as the protuberances (17) pass in the cells (18), which allows the user to ensure that the desired functions have been activated.

  • Patent number: 7384190
    Abstract: The present invention concerns a crown for a timepiece comprising a disconnecting gear device for preventing damage to the components of the movement of the timepiece in which it is implemented. For this purpose, the crown is provided with a housing which houses a pipe, to which one end of a winding stem is connected, carrying at least one spring and a rigid ring secured to the crown and comprising notches adapted to cooperate with the spring. In common use, a rotation of the crown causes a rotation of the pipe and thus of the winding stem, via the rigid ring and the spring. Owing to the device according to the present invention, when the mechanical resistance to the rotation opposed by the winding stem, via the pipe, exceeds a predefined threshold, the spring is deformed and is no longer driven in rotation by the rigid ring. Consequently, the winding stem is no longer driven in rotation in such conditions.
