    Technical area
    The present invention relates to a control device for activating and / or deactivating one or more features of a watch movement mounted in a sealed housing.
    State of the art
    A pusher is often used to activate and / or deactivate one or more features of a watch, such as start, stop and reset functions of a chronograph or a counter, likewise than the stop of the pendulum on certain watches. It can also be used to adjust / correct different functions of the watch (time / date for example). This pusher, generally placed on the middle of the case of the watch or on its bottom, typically comprises a button secured to a rod whose end comes into contact with one of the levers controlling the function. The pusher is returned to its initial position by a small coil spring placed generally between the button and the middle part, or between the button and the bottom.
    The sealing of such a pusher is difficult to achieve. One or more seals are generally interposed between the rod and the driven guide tube.
    FR 1 560 396 discloses a conventional pusher operating with a series of superimposable joints with a sliding sheath. The tightness of this system is achieved by means of very flexible plastic washers stacked on the rod of the pusher to have a greater stroke, while keeping compression at rest.
    The document CH 165 205 discloses a control device comprising a flexible partition that can flex to form a control member of the mechanism through a cone that carries in its center and is intended to act on a lever.
    JP 57 003 070 discloses a control button placed on the bottom of the watch case and consisting of a rigid disk comprising a flexible peripheral portion. The disk and the peripheral portion may be overmolded on the bottom so as to seal the housing. This solution has the advantage of providing a compact control button but this to the detriment of the strength of the bottom of the housing that includes the flexible peripheral parts.
    None of the proposed solutions can achieve a push or control device whose manufacture and integration in the watch are simple and compact, while not altering the sealing qualities of the housing.
    Brief summary of the invention
    The present invention relates to a control device for activating and / or deactivating one or more features of a watch movement mounted in a case of a waterproof watch comprising a middle part and a bottom; the device comprising a flexible membrane extending into the housing, between the bottom and the movement; the membrane being fixed on a circumferential portion between the middle and the bottom so that a free portion of the membrane can move relative to the movement; the membrane comprising an insert mounted integrally on the free portion of the membrane; the insert being movable between an actuated position in which the insert cooperates with the movement to activate and / or deactivate said one or more functionalities and a rest position where the insert does not cooperate with the movement. Preferred embodiments are indicated in the dependent claims.
    The manufacture and integration of the control device in the watch are simple and economical. The control device has a small footprint and its operation does not affect the sealing qualities of the housing.
    Brief description of the figures
    Examples of implementation of the invention are indicated in the description illustrated by the appended figures in which:<tb> Fig. 1 <SEP> is a perspective view in section of a watch case in which is housed a movement and comprising a control device, according to one embodiment;<tb> fig. 2 <SEP> shows a sectional view of the membrane, according to one embodiment; and<tb> fig. 3 <SEP> is a sectional view of a portion of the housing, with the movement and the control device.
    Example (s) of embodiment of the invention
    FIG. 1 illustrates a perspective view in section of a casing 1 of a sealed watch in which is housed a watch movement, for example mechanical, electronic, electromechanical, or other. The housing 1 comprises a middle part 3 and a bottom 4 fixed to the middle part, for example by means of screws 11. FIG. 1 also shows an ice cream 6 sealingly secured with a gasket 7 on the housing 1. A control device 20 for acting on a movement 5. The control device 20 is intended to activate and / or deactivate one or more functions of the movement 5 of the watch from the outside of the case 1. FIG. 3 shows a sectional view of a portion of the housing, the movement 5 and the control device 20.
    According to one embodiment, the control device 20 comprises a flexible membrane 10 extending in the housing 1, between the bottom 4 and the movement 5. A circumferential portion 8 of the membrane 10 (the entire circumference of the membrane is a part of this circumference) is fixed on the housing 1, between the middle part 3 and the bottom 4, so that a free portion 16 of the membrane 10 can move relative to the movement 5.
    In the example illustrated in FIGS. 1 and 3, the membrane 10 extends radially, that is to say, substantially parallel to the plane of the movement 5, represented by the axis 30 in FIG. 3. A spacing 21 is provided between the movement 5 and the bottom 4 so that the free portion 16 of the membrane 10 can move axially between the bottom 4 and the movement 5, that is to say, substantially perpendicular to the plane of the movement 5, represented by the axis 31 in FIG. 3.
    In a preferred embodiment, the membrane comprises an insert 9 mounted integrally on the free portion 16 of the membrane 10. FIG. 2 shows a sectional view of the membrane 10 alone with the insert 9. The insert 9 is typically made of a material that is more rigid than the material in which the membrane 10 is made. The insert 9 thus serves as a functional organ actuator to be actuated by a user. When actuated, by a pressure directed towards the movement 5, the insert 9 moves axially so as to cooperate with the movement 5 and activate and / or deactivate said one or more functionalities of the movement 5. The elasticity of the membrane 10 enables the insert 9 to return to the rest position when no longer actuated. In other words, the insert 9 is configured to move between a rest position, corresponding to a position where the insert 9 does not act on the movement 5, to an actuated position, where the insert 9 acts on the movement . The axial displacement of the insert 9 is illustrated by the arrow 22 in FIG. 3.
    In an advantageous configuration, the insert 9 comprises an anchor 15 extending from the membrane 10 in the direction of the bottom 4. The insert 9 can also be fixed on the membrane 10 with the aid of a clearance 17 provided in the insert 9. The seal between the insert 9 and the membrane 10 is then ensured by overmolding the material of the membrane 10 in the clearance 17 (FIG 2).
    Still in one embodiment, an opening 14 is formed in the bottom 4 so as to allow access to the insert 9 from the outside of the housing 1. In particular, and as illustrated in FIGS. 1 and 3, the opening 14 can be arranged concentrically with the insert 9. In this configuration, at least a portion of the pin 15 is housed in the opening 14 and slides therein when the insert 9 is moved between the rest position and the actuated position. This arrangement allows a user to actuate the insert 9 from the outside of the case 1. In addition, the wall of the opening 14 serves as a guide member for the ankle 15.
    The insert 9 can be actuated by a pressure supplied directly by the user or by means of a corrector tool (not shown). Particularly in the case where a corrective tool is used, the pin 15 may comprise a groove 18 facilitating the insertion and maintenance of the corrector tool in the pin 15 during actuation.
    In another variant not shown, at least a portion of the bottom 4 is flexible. The insert 9 can then be actuated by pressure on said flexible bottom portion. The flexible bottom portion may comprise a thinned portion of the bottom 4, sufficiently flexible so as to provide axial displacement for actuating the insert 9. The flexible bottom portion may also comprise a flexible portion actuating a more rigid portion cooperating with the insert 9. For example, the flexible portion may take the form of a corrugated portion and the more rigid portion of a disk so as to form a push button.
    The control device 20 of the invention therefore serves to fulfill the function of a push button so as to activate and / or deactivate one or more functions of the movement 5, such as setting the time, the launching a stopwatch function, etc. The control device 20 also makes it possible to seal the housing 1.
    The seal can, in fact, be provided by the fixing of the membrane 10 by compression on its circumferential portion 8, between the middle part 3 and the bottom 4.
    Preferably, the circumferential portion 8 of the membrane 10 comprises an extra thickness 12 which, when the membrane 10 is fixed between the middle part 3 and the bottom 4, plays the role of an O-ring.
    In one embodiment, the membrane 10 is made of elastomer. Preferably, the elastomer comprises a butadiene-acrylonitrile copolymer (nitrile butadiene rubber, NBR).
    In a variant, the ankle 15 and / or the insert 9 are made of a precious metal or alloy, such as gold or a gold alloy. This is advantageous when the peg 15 is visible from outside the housing 1, for example through the opening 14.
    The manufacture and integration of the control device 20 in the watch are simple and economical. The controller 20 also has a small footprint. The actuation of the control device 20 does not alter the sealing qualities of the housing 1.
