  • Publication number: 20110228646
    Abstract: Winding crown for a timepiece, said crown (40) including a bottom (42) and a skirt (44), which delimits an inner volume housing at least one elastically deformable element, the crown (40) being characterized in that a stop member is inserted between the elastically deformable element (50) and the bottom (42) of the crown (40) to prevent any surface contact between said elastically deformable element (50) and said bottom (42).

  • Publication number: 20110176394
    Abstract: Winding crown for a timepiece, said crown (32) including an uncoupling mechanism (1) comprising a rigid drive ring (4, 400) secured to the crown (32) and cooperating with at least one elastically deformable element (2; 200) secured to a pipe (12) to one end of which a winding stem is secured, the rigid ring (4; 400) driving the deformable elastic element (2; 200) in at least one rotational direction until the resistant torque opposed by said elastic element (2; 200) exceeds a threshold value beyond which said elastic element (2; 200) is deformed so as to interrupt the drive connection thereof with the rigid ring (4; 400), the elastically deformable element (2; 200) therefore having means for temporary coupling said element to said rigid drive ring (4; 400), the crown (32)) being characterized in that the elastically deformable element (2; 200) includes means for centring said element relative to the rigid drive ring (4; 400).

  • Publication number: 20100061194
    Abstract: The invention relates to a mechanism for the positioning of wristwatch control elements, whereas such control element may be implemented as a crown intended for the adjustment of the watch—as well as winding up the energy storage spring, for mechanical watches—or a pushbutton, and it is embedded in a hole in the watch case in an axially movable manner. The position mechanism contains a seat for the control element, as well as an actuating element linked to the control element from the side through at least one drive element designed to move the control element in its normal position countersunk in the seat, or one or more elevated operating positions.

  • Patent number: 7563020
    Abstract: 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).

  • Patent number: 7357569
    Abstract: A crown lock structure for a timepiece has a crown having an inner surface provided with a threaded section and a connecting assembly for removably connecting the crown to a case of the timepiece. The connecting assembly comprises a tubular member for integral connection to the timepiece case and a tubular insert removably connected to the tubular member. The tubular member has a first tubular portion for insertion into a through-hole of the timepiece case and a second tubular portion integral with the first tubular portion and removably connected to the tubular insert so as to prevent relative rotation between the tubular member and the tubular insert. The tubular insert has a threaded section for threaded engagement with the threaded section of the crown to removably connect the crown to the timepiece case.

  • Patent number: 7001064
    Abstract: The invention concerns a push-piece control device for a watch comprising a case (10) provided with a middle (12), an arbor (16) integral with a crown (20) and mounted pivoting in the middle (12) and a push-piece (18) mounted sliding and coaxial to the arbor (16). The invention is characterized in that it further comprises a lever (32) mounted pivoting on said case (10) by one of its ends (32a), mobile in a plane substantially parallel to the watch plane, including, in its median part (32b), a contact point designed to co-operate with said push-piece (18) and, at its other end (32c), a concave control portion.

  • Patent number: 6939034
    Abstract: The mechanism for transmission of axial and rotative movements between two portions of a stem with offset axes, includes a movable assembly movable axially. The section portion of the stem carries a second pinion and is pivoted on said movable assembly but it is axially secured to, this movable assembly. The first portion of the stem is pivoted on the movable assembly but axially secured to this latter and is secured to a first pinion, one or an uneven number of reverser(s), pivoted on the movable assembly kinematically connects the first pinion to the second pinion.

  • Patent number: 6679624
    Abstract: When using wristwatches for diving or action sports, it is desirable to be able to prevent the winding button from being pulled out inadvertently and the time unintentionally altered. To avoid this, the button (3) has the overall shape of an H and a lever (2) engages in the groove (10) in said button (3) to prevent this button from being pulled out in error.

  • Publication number: 20030128632
    Abstract: A fascia wash luminaire has a housing, a lamp socket and a refractor lens. The lamp socket mounts within the housing and is designed to hold a lamp in place within the housing. The refractor lens is trough shaped and is also held by the housing positioned under the light generation region for focusing the light from the light generation region to the fascia more broadly beneath the luminaire and more narrowly to the sides of the luminaire. The lens is shaped such that the distance between the lens and light generation region is smaller directly under the light generation region than it is on either side of the light generation region. The luminaire may also have a reflector for boosting the light directed downward and diagonal to the luminaire.
