    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0008] The invention relates to a timepiece 20, in particular a watch.
    This box 20 comprises at least one housing 26, in which is guided a pusher 1, including and not limited to the reassembly or rearming of a mechanism, or for the supply of energy to a storage means or a mechanism or a user circuit.
    This pusher 1 is movable, in a single curvilinear path, against elastic return means 15, and it comprises a control member 2, such as a ring or the like, which is arranged to be operated at least according to the curvilinear trajectory by pressure of a user against elastic return means 15.
    In non-illustrated variants, the control member 2 may be pivotally operated, or comprise a coaxial secondary member controlled in translation or / and pivoting.
    This control member 2 is integral with drive means 30, for the supply of movement and / or energy to the consumer function of the timepiece.
    According to the invention, the pusher 1, or respectively the box 20, comprises a cam track 18 closed and flat. And the box 20, or respectively the pusher 1, comprises, at the end of a pivoting arm 17 around a pivot 19 fixed to the box 20 or to the pusher 1, a guide pin 16, which is arranged to follow the profile of the cam track 18.
    This pivoting arm 17 is arranged to pivot in a plane parallel to that of the cam track 18.
    The cam track 18 comprises at least two bends pointed towards the pivot 19 and defining stable positions 23, 24, of the guide pin 16, which correspond to stable positions of the control member 2.
    The invention is illustrated in a nonlimiting manner, in the figures, with two such bends, and two stable positions.
    The profile of the cam track 18 comprises ramps, which are arranged so that any pressure on the control member 2, when it is off, each stop position corresponding to a stable position 23,24, causes the output of the guide pin 16 of this stable position 23, 24, and allows its travel, under the action of the elastic return means 15, to another stable position 24, 23.
    More particularly, the profile of the cam track 18 is arranged to impose a one-way path of the guide pin 16 in the cam track 18.
    Advantageously, to facilitate changes in position of the guide pin 16 relative to the cam track 18 during relative movements from one to the other, these at least two elbows are shifted transversely relative to at the pivot 19 along the path, as shown in FIG. 7.
    This fig. 7 illustrates a particular non-limiting embodiment, where the cam track 18 comprises: between a first stable position 23 corresponding to an axial end of the stroke of the pusher 1, and a first unstable position 21, a first branch C to be traversed by the guide pin 16 under the action of a pressure of the user on the control member 2; - Between the first unstable position 21 and a second stable position 24 a second branch D to travel through the guide pin 16 under the action of the elastic return means 15; - Between the second stable position 24 and a second unstable position 22 a third leg A to go through the guide pin 16 under the action of a pressure of the user on the control member 2; - And between the second unstable position 22 and the first stable position 23 a fourth branch B to go through the guide pin 16 under the action of elastic return means 15.
    The black arrows in the figure corresponding to the paths C and A relate to the phases of movement under the action of a pressure of the user on the control member 2, while the white arrows corresponding to the paths D and B relate to the phases of movement performed under the action of the elastic return means 15. It is the same with fig. 3 to 6, which illustrate respectively from the stop position of FIG. 2, the different paths A, B, C and D. The two stable positions of the pusher 1 correspond to elongations L1 and L3 of the end of the control member 2 with respect to a reference surface of the box 20, while the unstable transient positions of figs. 3 and 5 correspond to an elongation L2 (which could take different values between one and the other depending on the shape of the profile of the cam track 18, which, in the example of FIG. longitudinal gap between the first stable position 23 and the first unstable position 21 on the one hand, and between the first stable position 23 and the second unstable position 22 on the other hand, but these differences could also be different. , the branch C has two ramps of opposite direction, with an inflection position 26, and the branch B has a straight part followed by a ramp after the passage by an inflection position 25.
    More particularly, the pivoting arm 17 is free to pivot, its pivoting results from the relative positioning between the cam track 18 and the pivot 19 during the relative stroke of one relative to the other.
    More particularly, the curvilinear trajectory is flat, as in the case of the figures.
    More particularly, the curvilinear trajectory follows a linear direction DL.
    More particularly, the drive means 30 comprises at least one rack arranged to cooperate with an input mobile 31 that includes the box 20.
    In other variants not shown, this drive means may be a single finger actuating a rocker or the like, a friction, a spring, or other.
    More particularly, for an economical embodiment illustrated by the figures, the elastic return means 15 comprise at least one helical spring housed in a chamber or in a tube 12 housed in a bore of the box 20 and in frontal support on a stop 13 comprising an axial guide of the spring. In the variant illustrated, FIG. 1 shows such a tube 12 in a bore of the box 20, this tube 12 is secured to a bracket fixed by screws 11 to a structural member of the pusher 1; the tube 12 preferably comprises a bore or the like for the evacuation of air. The abutment 13 illustrated by the figures consists, in a non-limiting manner, in a plug housed in the bore of the box, and which comprises an axial inner guide of the spring. Another variant is to accommodate the spring in a front groove in the box 20. In the variant where the trajectory of the pusher is linear, it is important to ensure proper alignment between the control member 2 and the tube 12 .
    More particularly, the pusher 1 comprises a plate 9 substantially flat in which is formed the cam track 18, and which constitutes such a structural element, and which is fixed by another screw 10 to the control member 2 [0029] More particularly, the pusher 1 comprises, at this control member 2, a cylindrical portion 6 which comprises at least one groove 7 for housing at least one seal 8 in contact, on the whole the stroke of the pusher 1, with a cylindrical bore that comprises the housing 26 of the box 20.
    Figs. 9 to 20 illustrate another construction variant with a few more components as it is designed for easier assembly and disassembly.
    This non-limiting variant comprises, to improve the stability of the pivoting lever 17, a bistable spring, which is a jumper 43, which acts on a rear profile 56 of the pivoting lever 17, which rear profile 56 is substantially Vee male.
    Other alternative solutions may also be suitable to improve the stability of the pivoting lever 17: friction by a polymer seal or the like on the axis, lanternage, interposition of a foil, lateral friction spring, bistable spring. The drive means 30 here also includes a rack. A single component in the form of a substantially flat plate 9 includes this rack 30, the cam track 18, and a first pin 47 for guiding the elastic return means 15, which again include at least one coil spring. . The latter is guided at its other end by a second pin 130, housed in a bore 58 of the box 20. The plate 9 further comprises a pin 44, which extends on either side of a flat portion of the 9, and which is perpendicular to the first pin 47, which extends in the plane of the box 20. An implantation 55 is intended to receive a pin or a screw 46 for fixing a connecting plate 41, through of an orifice 53 that it comprises, on the plate 9, positioned by the pin 44 in a bore 54 of the connecting plate 41.
    This connecting plate 41 has an opening 51 of profile complementary to that of a boss 52, which here comprises the end of the cylindrical portion 6 of the control member 2. The opening 51 and the boss 52 are here substantially square, so as to ensure the parallelism of the rod 2 of the pusher 1 and the rack. The immobilization is then made by a screw 45 fixed in a tapping that includes the boss 52. The cylindrical portion 2 can be, thus, very short, and the assembly is greatly facilitated.
    The lower part of the pin 44 cooperates advantageously with a first oblong groove 48, which comprises the box 20. At the opposite, another pin 59 integral with the plate 9 slides in a second oblong groove 49 of the box 20 Naturally reverse guidance is also possible, but consumes more space.
    A cover cover 42, or an armoring bridge, limits the movement of the various components, and in particular prevents any buckling of the spring 15.
    The invention also relates to a timepiece, including a watch 100, comprising such a box 20, and an input mobile 31 cooperates with a mechanism or a means of transformation or / and energy storage.
    In a variant, the watch 100 includes a minute repetition mechanism controlled by a pusher 1, which is an advantageous alternative to the usual targets.
    In another variant, the watch 100 comprises at least one energy storage barrel and at least one pawl between an input mobile 31 and the at least one barrel.
    In another variant, the watch 100 comprises a plurality of pushers 1.
    The possibilities of the invention are very wide.
    In its application to a winding function, the invention provides great maneuverability for ladies watches, small watches, watches and flat, and the like.
    The invention allows, again, the reduction of space in the movement, in particular through the use of a substantially flat control mechanism.
