    TECHNICAL FIELD [0001] The present invention relates to the field of watchmaking, particularly mechanical watchmaking. It concerns watches, pocket or wrist.
    STATE OF THE ART [0002] Various types of display or play systems are known in the field of watchmaking. The present invention aims to propose a new, and a playful and original mechanism for creating an energy sensor or activity sensor. In other words, the proposed system makes it possible to account for the movements (and therefore the activity and / or the energy level) of the wearer.
    Disclosure of the invention [0003] More specifically, the invention relates to a watch comprising a differential equipped with: a first input intended to be driven by a rotation R1 by a flyweight mounted freely movable in rotation on an axis , without the interposition of a barrel between the flyweight and the differential, - a second input intended to be driven by a rotation R2 by a time base, - an output transmitting a rotation corresponding to aR1-bR2.
    Thus, the output of the differential reflects the movements of the wearer of the watch over a period of time. The coefficients a and b can be adapted, in particular by adjusting the gear ratios of the differential. The output rotation is said positive for rotations of the flyweight generated by the movements of the wearer, this output rotation being reduced by a rotation related to the time that passes, taken on the basis of time.
    BRIEF DESCRIPTION OF THE DRAWINGS Further details of the invention will appear more clearly on reading the description which follows, given with reference to the appended drawing in which FIG. 1 is a schematic representation of the mechanism of a watch according to the invention.
    Embodiment of the invention [0006]
    Fig. 1 represents in the form of a block diagram, the main elements of a watch according to the invention. This comprises a differential equipped with: a first input intended to be driven by a rotation R1 by at least one flyweight freely movable in rotation on an axis, without the interposition of a cylinder between the flyweight and the differential, a second input intended to be driven by a rotation R2 by a time base; an output transmitting a rotation corresponding to aR1-bR2.
    The flyweight can be of the type of oscillating masses generally used in automatic winding mechanisms. By free rotation, it is meant that the weight moves under the influence of the user's movements and weight. It will be possible to use a rotor mounted to move on an axis of rotation located in the center of the movement or one or more micro-rotors, possibly eccentric with respect to the center of the movement. For the freest possible rotation, it is preferable to mount the counterweight on a ball bearing. It is integral and coaxial with a pinion, by which it is kinematically connected to the first input of the differential. Preferably, it is possible to integrate between the flyweight and the first input of the differential, an inverter system so that rotations of the flyweight performed in both directions lead to the first input of the differential in the same direction. Alternatively, it is also possible to integrate between the flyweight and the first input, a unidirectional drive system, so that only the rotations made in one direction are transmitted to the first input of the differential. The flyweight can perform full or partial rotations.
    The second input is kinematically connected to a mobile linked to the time base, for example to a mobile of the work train. This mobile is rotated when the watch is in operation.
    For the differential, the skilled person is well aware of this type of mechanism and we do not need to describe a particular example. The differential is arranged in such a way that it outputs, information corresponding to the rotation R1 transmitted to the first input from which is subtracted the rotation R2 transmitted to the second input. If necessary, we can still intervene, at the differential or upstream kinematic chains, coefficients a and b, in order to adapt the transmission ratios rotations R1 and R2.

    Claims (11)
    [1]
    Thus, in the event that the watch is not in function, it is obtained at the output of the differential, a rotation in one direction, defined arbitrarily as positive, when the watch is agitated and that the weight is driven in. rotation according to the movements of the wearer. Rotation in one direction, defined arbitrarily as negative, is obtained when the watch is not agitated and the movement is in operation. In practice, in practice, the output of the differential provides the difference R1-R2, with the ratios a and b near. We can define a and b, depending on the speed at which we want to see evolve the information provided at the output of the differential. The output of the differential can be kinematically connected to a display member, for example a board having a display sector, intended to be visible through a window, or a needle. The display member reaches a maximum level when the user has moved his watch sufficiently for a short period of time, insufficient for the rotations brought to the second input prevents it from reaching said maximum level. Note that this system is not an indication of power reserve since there is no cylinder kinematically connected between the flyweight and the input of the differential. No input of the differential is kinematically connected with the winding of a barrel, to receive information that would come from said cylinder. When the display member has reached said maximum level, it can be provided that it remains blocked at said level as it receives a positive rotation, or it returns to the minimum level. This can be achieved by positioning the display member by means of a cam, driven by the output of the differential and a feeler. If the cam is not limited in rotation, we can have a return to the minimum level. If the cam is limited in rotation by a stop, the display member may remain at the maximum level. It is also possible to kinematically connect the output of the differential to an energy storage member, the output of the differential being arranged to provide energy. Typically, it is thus possible to provide a spring, for example integrated in a barrel, intended to be armed by the output of the differential, when the latter is driven in the direction of rotation previously defined as positive. In an advantageous variant, the watch comprises an additional mechanism, intended to be supplied with energy by said energy storage member. A trigger system is then arranged to release said energy storage member when it has been armed in a predefined stroke. Thus, when the barrel has been armed with a certain amount of energy since its previous release, so that it has been driven in a predefined stroke, resulting from the different between the rotations R1 and R2, the system of trigger releases it, for a defined period, during which the additional mechanism is in operation. This additional mechanism may be a mechanism generating a vibration, including sound. It may be a ring, possibly a vibrator, already described for mechanisms of "discreet ringing". The additional mechanism then has its own control gear, which can be kept locked at rest, and released by the trigger system. The additional mechanism may be an animation mechanism, for example having a partially transparent or perforated disc capable of being rotated and which, depending on its angular position, may alternatively show a pattern, possibly made of a luminescent material. Thus, when the disc rotates under the action of the energy storage member, the intermittent appearance of the pattern gives a blinking effect. It can be provided that the additional mechanism operates for a limited time and is then blocked automatically. Alternatively, the additional mechanism may have its own source of energy, that is to say that it is not supplied with energy by the output of the differential. The additional mechanism can therefore be armed by a pusher or a crown, and be triggered by the triggering system, for example when the display member has reached its maximum level. The display member may also be a counter, incremented each time the output of the differential has been driven by a certain positive rotation. It can also be decremented when the differential output is negatively driven. If need be, a reset system can be provided with a pusher and a hammer / heart device. The counter may, for example, be coupled to a needle or a disc, as proposed above, and be incremented each time the display returns to its minimum position (after a positive rotation of the output). Even in the case where there is an energy storage member connected to the output of the differential, the present invention can not be considered a power reserve display because there is no one-to-one correspondence between a position of the display member, when there is one, and the arming level of the energy storage member. claims
