    Description of an embodiment
    Figures 1 and 2 show in detail the main components of a watch module 1 according to the present invention in a preferred embodiment. This watch module 1 is advantageously designed to provide, in association with a mechanical or electronic watch movement M (FIG. 3A), a tracer or physical activity counter function complementary to the counting and display of the current time and/or dates or usual periodic events in the field of watchmaking. This clock module 1 has the advantage and the advantage of being entirely mechanical and requiring no specific power supply.
    [0011] It comprises for this purpose means 2, 3, for generating a motor torque in response to a movement of said watch module 1 in the three dimensions of space carried on a member of a user, typically but not exclusively one arm of the user. These motor torque generation means then transmit via a motor train 4, 5, 6 said torque to a motor energy accumulation mechanism arranged in kinematic connection with a display device. The torque generation means 2, 3, the motor train 4 5, 6 and the energy accumulation mechanism are advantageously configured so that the information displayed by the display device is representative of the physical activity of the user. In particular, the dimensioning, the masses and the gear ratios of the mobiles forming the torque generating means 2, 3 and the motor cog 4, 5, 6 can be chosen according to the user and his average physical activity. without having to calibrate or adjust the display device according to the user.
    [0012] More specifically, the watch module 1 firstly comprises a plate P, commonly machined and counterbored to receive the components and mobiles of the module 1 as described below, from the input of the kinematic chain of the module established by the means for generating the engine torque until the output of said kinematic chain at the level of the display device.
    [0013] Referring to Figures 1 and 2, the input of the kinematic chain of the inventive module 1 is formed by means for generating a motor torque in response to a movement of said watch module in space. These torque generation means comprise an oscillating mass 2, the shape, dimensions and mass of which can be chosen individually by the user. This oscillating mass 2 is secured to a driving pinion 3, this mass-driving pinion assembly being pivotally mounted on the plate P via a one-way bearing, in a conventional manner per se. Thus, the oscillating weight 2 is the source of a driving torque during its rotational movements, driving torque which is transmitted directly in a single direction of rotation, in this case counterclockwise in FIG. 1, by the driving pinion 3. The latter meshes by its external teeth with a first mobile 1 of a gear train for transmitting torque to a drive energy accumulation mechanism. This first mobile 4 is formed of a toothed wheel 41 secured to a coaxial pinion 42 (fig. 2), pivotally mounted on the plate P by driving in or screwing. The first wheel set 4 meshes via the pinion 42 with a second wheel set 5 of the transmission gear train, also composed of a toothed wheel 51 carrying a pinion 52, both of which also pivot on the plate. This second wheel set 5 meshes via its pinion 52 with a last wheel set wheel 6, in this case identical to the second wheel set 5 and composed of a toothed wheel 61 and coaxial pinion 62.
    [0014] The toothed wheels 51, 61 have on their radial branches orifices advantageously provided for adjusting ballast and/or balancing masses or even for the wheel 61 more particularly, to fix one or more finger(s) 7 of increment intended to drive in rotation a starwheel of increment 8 pivoting on the plate P and forming the input wheel set of the energy accumulation mechanism of the module 1, which also comprises a ratchet wheel 9, a spiral spring 10, and a pawl rocker 16.
    The increment star 8 comprises six branches 81 regularly distributed and diametrically oriented in pairs around the central axis of rotation of the star 8. Said branches 81 of the increment star 8 intersect the trajectory circular described by the end of the finger(s) of increment 7 carried by the mobile 6 in such a way that the latter(s) necessarily engage and push(es) during its rotation on the branches of the star 8 so as to cause the latter to pivot on itself counterclockwise. In addition, the branches 81 of the star 8 also intersect the peripheral path described by the wolf teeth 91 of a ratchet wheel 9, pivotally mounted by a rotation shaft 92 on the plate P and cooperating with the ratchet rocker 16 pivoted on the plate P and elastically returned by a leaf spring 17 against the ratchet wheel 9.
    [0016] Thus, the rotation of the increment star 8 under the action of the increment finger 7 and the transmission cog causes a clockwise rotation of the ratchet wheel 9. This rotation is possible by the form triangular wolf teeth 91 of the ratchet wheel whose inclined plane is advantageously oriented to slide on the inclined plane of the beak 161 of the pawl rocker 16, pushing the latter so as to take a step in the clockwise direction only. The ratchet wheel 9 is integral in rotation via its shaft 92 with a spiral spring 10 arranged to accumulate an elastic return energy at each step of the ratchet wheel 9 and hence to return the latter counterclockwise. The counterclockwise return of the ratchet wheel 9 is however prevented by the ratchet rocker 16 by the combined effect of the beak 161 resting flat on the right field of the wolf teeth 91 and of the spring 17 opposing the rotation of the pawl rocker 16 during such flat support.
    The ratchet wheel 9 is also integral with a toothed wheel 11 for driving the display device. The toothed wheel 11 meshes by its peripheral toothing with a toothed mobile 12 for display driven on the plate and whose rotation shaft is integral with a needle 20 for displaying the physical activity of the user, according to terms described below.
    [0018] During the step-by-step rotation of the ratchet wheel 9, the toothed wheel 11 also drives the display mobile 12 in rotation and thus the display needle. The advancement of the ratchet wheel 9 being dependent on the torque transmitted by the gear train 4, 5, 6 from the oscillating mass 2 set in rotation by the movements of the user's arm, the hand 20 therefore provides a direct indication, where appropriate in cooperation with a scale formed or printed on a dial C (FIG. 2) of the effective level of activity of the user over a given period of time, typically preferably 24 hours. Alternatively, the mobile display 12 can itself carry a numerical or colored index or scale indicating the accumulated mechanical energy and therefore the physical activity of the wearer, which can be visible through an aperture of the dial. vs.
    [0019] The energy accumulation mechanism is for safety designed to accumulate only a finite quantity of energy, capable of being stored by the spring over a complete revolution of the ratchet wheel 9. Also the toothing of the ratchet wheel 9 comprises for safety a zone 92 of recess free of teeth 91 of length at least equal to the pitch separating two branches 81 of the increment star 8. Thus, the increment star 8 does not can no longer, once one of its branches have fallen into this zone 92, transmit torque to the ratchet wheel 9 because it will no longer turn except freely under the action of the cog, without being able to engage a wolf tooth 91 of the ratchet wheel 9.
    Advantageously, the module 1 is configured such that the star 8 falls into the recess area 92 of the ratchet wheel 9 when the display hand 20 reaches a position corresponding to a maximum display of activity. This maximum position, and the antagonistic position of minimum activity can be advantageously determined by a pin 22 driven on the plate into a corresponding orifice and also extending into a slider or groove 23 machined in the plate of the toothed wheel set. display 12.
    [0021] Moreover, in order to provide a useful display for the user to evaluate his daily activity, it is necessary for the latter to be able to perform a reset of the activity display, and therefore of the needle 20, at the least once a day, whether or not the aforementioned maximum display position has been reached. The module 1 comprises for this purpose a manual reset lever 19 arranged on the ratchet rocker 16, and intended to cooperate with a slider or sliding lock arranged on the middle of a watch case receiving the watch module 1 of the invention associated with the movement M. Pressure on the lever 19 tends to cause the ratchet rocker 16 to pivot in a clockwise direction, then disengaging the beak 161 from the teeth 91 of the ratchet wheel 9, which is then free to rotate on its shaft and therefore driven by the spiral spring 10 in an anti-clockwise direction, thus bringing the display hand back to the "zero" position. By this means, the user can easily, at his convenience, perform the reset of the display device.
    The watch module 1 of the invention, however, also includes an automatic release mechanism for the ratchet wheel 9 and for resetting the display device, substantially on passing midnight. This mechanism consists of a toothed wheel set 13 adapted to be coupled to the barrel or hour wheel set of the movement M. This toothed wheel set 13 meshes with a zero-reset toothed wheel 14 to which an elastic trigger finger 15 is attached. This reset wheel 14 is configured to make one revolution in 24 hours and the elastic finger 15 positioned on it to engage a release lever 18 of the ratchet rocker 16 between 11:55 p.m. and 12:00 a.m. Upon contact between the trigger finger 15 and the release lever 18 the finger 15 deforms elastically by spring effect up to a stop 151. Once this stop has been reached, approximately at 24 o'clock, the finger 15 pushes the lever 18 and rocks the ratchet rocker 16 on its axis, in a clockwise direction, then disengaging the beak 161 from the teeth 91 of the ratchet wheel 9, which is then free to rotate on its shaft and therefore driven by the spiral spring 10 in a clockwise direction. anti-clockwise, then bringing the display hand 20 back to the "zero" position. By this means, the automatic reset of the display device of the module of the invention is obtained every day at 24 hours.
    [0023] In an alternative embodiment of the automatic reset mechanism, the toothed wheel set 14 may instead of the finger 15 include at least one pin arranged to engage the release lever 18 of the pawl rocker 16 so as to pivoting said pawl rocker when switching to 24 o'clock.
