    The invention relates to a pusher crown comprising a crown (4) provided with a central extension (10) adapted to be connected to a winding stem of a clockwork movement and a pusher (5) which is axially displaceable with respect to The crown (4) against an elastic action. This pusher crown further comprises a tube (8) able to pass through the wall of a watch case and to be fixed thereto on which the crown (4) is pivoted. The pusher ring includes a locking device (12, 19, 20) preventing actuation of the pusher (5) so long as the crown (4) is not placed in at least one predetermined angular position with respect to the tube ). The invention also relates to a timepiece comprising such a crown.

    Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to pusher crowns for timepieces. A pusher crown is a crown which can be used for winding, setting and adjusting the date which includes a central pusher which enables a mechanism of the timepiece movement to be actuated, for example a chronograph, a counter Or any other complication.
    A disadvantage of these pusher crowns is that the pusher can be actuated at any time and thus can be actuated inadvertently during an impact of the timepiece, which is not desirable.
    The object of the present invention is to obviate this disadvantage by providing a safety device preventing any actuation of the pusher when the crown is not in a determined angular position causing the safety device of the pusher to be released. Thus, in order to actuate the pusher and thus the corresponding complication, it is first necessary for the user to place the ring in a predetermined angular position.
    SUMMARY OF THE INVENTION The present invention relates to a pusher ring, in particular for a timepiece, comprising a safety device having the characteristics set forth in claim 1.
    The subject of the present invention is also a timepiece provided with a pusher ring including the safety device.
    BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawing illustrates schematically and by way of example an embodiment of the pusher ring provided with the safety device according to the invention.
    FIG. 1 is a top view of a watch with a pusher crown.
    FIG. 2 is a detail view on a larger scale in perspective of the pusher crown.
    FIG. 3 is a plan view on a larger scale of the pusher crown.
    FIG. 4 is an exploded view of the pusher crown and its safety device.
    FIG. 5 is a cross-section along the line AA in FIG. 1.
    FIG. 6 is a cross-section along the line CC in FIG. 5.
    FIG. 7 is a section on the line B - B of FIG. 6, the safety device being in the unlocked position and the pusher in the inactive position.
    FIG. 8 is a cross-section along the line CC in FIG. 5, the safety device being in the unlocked position and the pusher in the active position.
    The present invention relates to a pusher ring provided with a safety device preventing the actuation of the pusher as long as the crown is not positioned in a predetermined angular position thus preventing accidental, unintentional actuation of the pusher . The subject of the invention is also a watch equipped with such a pusher ring.
    The embodiment of the invention illustrated in the drawing is a wristwatch 1 comprising the pusher ring including the safety device.
    [0009] FIG. 1 illustrates in top plan a wristwatch 1 comprising a box 2 provided with a push-rod crown 3. This crown with push-button comprises a crown 4 comprising a notched periphery and a pusher 5 housed in a first external recess 6 which comprises the face This crown 4 also has a second recess 7 receiving a first end 8a of a tube 8 passing through the watch case 2 and fixed to it by driving and / or welding. In the mounted operating position, the ring 4 receives the first end 8a of the tube 8 and is pivoted on this end of the tube.
    The first recess 6 of the ring 4 is separated from the second recess 7 of this ring by a central wall 9 of the crown 4. The first end 8a or the head of the tube 8 is circular and serves as a pivot to the crown 4. The central wall 9 of the crown 4 has a central extension 10 coaxial with the crown 4 and extending coaxially inside the tube 8 and its head 8a. The free end of this central extension 10 is adapted to be connected to a winding and setting stem 11. In the example illustrated, the free end of the central extension 10 comprises a tapping 10a in which Screw the outer end of the winding and setting stem 11.
    The head 8a of the tube 8 comprises at least one blind or through hole 12 with an axis parallel to the axis of the tube 8.
    Slidably mounted and rotating in the tube 8 is a pusher pin 13 whose inner end is capable of cooperating with an actuating member 0 of a mechanism of movement contained in the box 2. The outer end Of this pusher shaft 13 comprises two coupling members 14 passing through the wall 9 of the ring through openings 15 in this wall 9. The end of these coupling members 14 includes a rim 16. These ends of the members
