    Technical area
    The present invention relates to the field of watchmaking and more specifically to a display of the power reserve on demand for timepiece.
    State of the art
    There are already in the state of the art many devices for displaying the power reserve of a mechanical or automatic watch. In general, these devices make it possible to display the power reserve continuously. For this purpose, the indicator member of the power reserve is secured to a wheel meshing with a gear wheel in engagement with the barrel and the ratchet of the watch movement.
    [0003] WO 2011/151717 describes a device indicating the power reserve on demand which produces an acoustic signal to indicate the amplitude of the power reserve.
    A power reserve display for producing an animation effect is however not known.
    Brief summary of the invention
    The present invention relates to a display device for a timepiece including a drive mechanism characterized in particular by the fact that it comprises at least one mobile animation that moves at the request of the user and which, at a time or successively, is able to move above the dial, and possibly cooperate with indications on the dial, to give an animation effect. The drive mechanism is also arranged to cooperate with an index on the dial to indicate the power reserve in an instantaneous manner. In other words, the race of at least one mobile varies depending on the power reserve while the same mobile or a second mobile also gives an animation effect unrelated to the indication of the power reserve.
    The present invention also relates to a display device comprising a drive mechanism configured to drive a mobile display so that the mobile display can move over a dial of the room clock; the drive mechanism comprising a user operable control for operating the drive mechanism and driving the display mobile on demand; the display mobile having a function of indicating the instantaneous power reserve of the timepiece and producing an animation effect unrelated to the indication of the power reserve.
    In an exemplary embodiment, the display mobile comprises a mobile power reserve indicator and an animation mobile.
    For example, the mobile animation can take the form of a tennis racket that moves from an initial position to near a tennis ball, shown on a dial of the timepiece when the control is operated. The mobile power reserve indicator may take the form of an arrow that moves from an initial position to a position to indicate the power reserve according to a mark on the dial.
    This solution has the advantage over the prior art that the power reserve display allows, on demand, to also produce an animation effect.

    Example (s) of embodiment of the invention
    A display device for a timepiece is shown in FIGS. 1 to 4, according to one embodiment. In particular, FIG. 1 illustrates a drive mechanism of the display device and FIGS. 2 to 4 shows details of a display mobile 40, 41 of the display device, according to one embodiment. With reference to FIG. 1, the drive mechanism comprises a control 12, operable by a user, for actuating the drive mechanism and drive, on demand, the display mobile 40, 41. The display mobile 40 , 41 is characterized in that it has a function of indicating the instantaneous power reserve of the timepiece and producing an animation effect unrelated to the indication of the power reserve. As illustrated in FIGS. 2 to 4, the drive mechanism can be configured to drive the display unit 40, 41 over a dial 50 of the timepiece.
    According to one embodiment, the drive mechanism comprises a peripheral ring 15 pivotable at the periphery of a movement of the timepiece. The drive mechanism is arranged such that actuation of the control 12 causes the peripheral ring 15 to pivot from an initial position, when the control 12 is not actuated, to a given pivot angle, when the control 12 is actuated.
    In the embodiment shown in FIG. 1, the control 12 includes a probe 13 arranged to move laterally when the control is actuated. A rake 16 is pivotally mounted about a pivot 16a. The rake 16 comprises an oblong hole 16b in which is housed a pin 13a integral with the feeler 13 so as to pivot the rake 16 when the probe is moved laterally following the actuation of the control 12. The rake 16 has a toothing 16c configured to engage a gear train 23a, 23b to drive the peripheral ring 15 in rotation when the rake 16 is rotated. The angle of rotation of the peripheral ring 15 up to the given pivot angle is thus determined by the amplitude of the displacement of the probe 13. In the example of FIG. 1, the rake 16 drives the peripheral ring 15 through a first wheel of the gear train 23a and a second gear wheel 23b, so that when the probe is moved towards the center of the movement, the peripheral ring 15 is rotated clockwise.
    The drive mechanism comprises a power reserve snail 22 rotated by the barrel 20 of the movement. Following the actuation of the control 12, the probe 13 comes into abutment against the reserve power reserve 22. The snail 22 is configured to pivot according to the power reserve so that, when the barrel is armed, the The probe 13 abuts against the lower sector of the snail 22. In this case, the movement of the probe 13 towards the center of the movement, as well as the pivoting of the peripheral ring 15 with a given pivot angle, is maximal.
    FIG. 2 shows the display 40, 41 when the control 12 is operated and for a maximum power reserve. In particular, in this example, the mobile display includes a power reserve indicator 40 mounted integral with the peripheral ring 15. In the case where the barrel is armed, the actuation of the control 12 pivots the indicator 40 maximum swing angle, corresponding to the position of the maximum power reserve.
    The snorkel 22 pivots as the barrel disarms. When the barrel is disarmed, the snail 22 is in a position such that, when the control is actuated, the probe 13 comes into abutment against the highest sector of the snail 22. In this configuration, the displacement of the probe 13 towards the center of the movement is smaller than when the barrel is armed and, consequently, the rotation of the peripheral ring is less. Fig. 3 shows the display 40, 41 when the control 12 is operated and for a minimum power reserve. In particular, the power reserve indicator wheel 40 is displaced vis-à-vis a second index 52 of the dial 50 indicating a minimum power reserve.
    The control 12 can be operated by means of a winding crown (pusher crown) 70 or a pusher (not shown).
    The peripheral ring 15 is subjected to the action of a return spring 14 which pushes on the control 12. When the control 12 is no longer actuated, the return spring 14 pulls the probe 13 in its position initial, which causes the peripheral ring 15 in its initial position. Fig. 4 shows the display 40, 41 in the initial position and, in particular, the mobile power reserve indicator 40 located opposite a first index 51 of the dial 50 which represents a rest position indicating no value of power reserve.
    Preferably, the drive mechanism comprises a speed control mechanism for regulating the speed at which the peripheral ring 15 is rotated in the initial position. In one embodiment shown in FIG. 1, the cruise control mechanism is composed of an eccentric mobile type "cat's eye" 18 having a toothing engaging, on the one hand with a second toothing 32 of the peripheral ring 15 and secondly with a flywheel including a first flywheel 19 and a second flywheel 19. The wheel of inertia drives an inertia mobile 26 in oscillation. The eccentric mobile 18 is configured to pivot only when the peripheral ring 15 is rotated to the initial position. The unbalance, or inertia, determined by the geometry and the mass of the inertia wheel 26 makes it possible to regulate the speed of rotation of the gear trains 19, 19 and therefore the speed at which the peripheral ring 15 is pivoted in the position initial.
    In one embodiment, the display mobile also includes an animation mobile 41, independent of the mobile power reserve indicator 40. The animation mobile 41 can cooperate with indications on the dial to give an animation effect, as in the examples of FIGS. 2 to 4, where the animation mobile 41 is represented in the form of a tennis racket 41 approaching or away from a tennis ball 41 shown on the dial 50. It is clear that the animation mobile 41 may take another form than that illustrated here. Alternatively, the mobile power reserve indicator 40 can also serve as an animation mobile.
    Referring again to FIG. 1, the animation mobile 41 is driven by means of an animation drive enabling it to move independently of the mobile indicating the power reserve 41.
    In the variant illustrated in FIG. 1, the animation drive comprises a finger 33 drivable to pivot by the second toothing of the peripheral ring 15. A mobile malta cross type 35 is configured to rotate on a fraction of a turn, for example a quarter turn, when the finger 33 engages with a recess 350 of the mobile maltese cross 35. The mobile maltese cross 35 in turn drives a carriage 37 carrying the animation mobile 41, through a toothing of the carriage.
    When the control 12 is actuated and the peripheral ring 15 is rotated clockwise, the carriage 37 moves in a circular arc concentric with the center of the movement, also in the clockwise direction. When the command 12 is no longer actuated, the peripheral ring 15 returns to its initial position, causing the carriage 37 and the moving object 41 to move to their initial position. Fig. 2 illustrates the animation mobile 41 in the form of the tennis racket 41 moved close to the tennis ball 41 when the control 12 is actuated. Fig. 4 shows the tennis racket 41 away from the tennis ball 41 when the control 12 is no longer actuated. In the example of FIG. 3 where the indicator 40 is displaced vis-à-vis a second index 52 indicating a minimum power reserve when actuating the control 12, the racket 41 is always moved to its position close to the tennis ball 41. Indeed, the movement of the carriage 37, and therefore of the mobile animation 41, following the actuation of the control is independent of the power reserve to the extent that the finger 33 can rotate the mobile maltese cross 35 the lower pivoting of the peripheral ring 15 in the case where the probe is limited in its movement by the snail 22 in the low power reserve position.
    In one embodiment, when the control 12 is actuated, the carriage moves at an angle which is about twice the maximum pivoting angle of the peripheral ring 15 (in the case where the power reserve is maximum). The drive mechanism may be configured such that the maximum pivot angle of the peripheral ring 15 is between 15 ° and 30 ° and preferably about 20 °.
    FIG. 5 shows a partial view of a movement of a timepiece in which the drive mechanism can be assembled. In fig. 5, the movement is shown comprising two motor barrels 20, however the drive mechanism could just as well work in a movement with only one barrel, where even more than two barrels. In the illustrated example, a sun gear 10 is driven by the barrel or barrels 20. The sun gear 10 in turn drives the power reserve limb 22.
    Figs. 6a and 6b show a view of a portion of the sun gear 10 and FIG. 6c a view of the complete sun gear 10. In particular, FIG. 6a shows a first input disk 101 of the sun gear 10, the disk 101 being rotatably mounted on a sun gear shaft 105. The first input disk 101 is intended to engage a board 21 of one of the barrels 20 so as to be driven by this board 21. An intermediate wheel 106 is mounted integrally on the first input disk 101 and rotates with the latter. In fig. 6b, an output disk 103 is shown concentrically on the first input disk 101 so as to be rotatable about the shaft 105, independent of the first input disk 101. The output disk 103 is arranged to engage with an output mobile 11 of the sun gear which drives the snail 22 (see Figs 1 and 5). Two planet wheels 104a and 104b are rotatably mounted in openings 108a and 108b formed in the output disk 103. In FIG. 6c, a second input disk 102 of the sun gear 10 is mounted on the output disk 103 and is arranged to engage a ratchet 30 of the other of the barrels 20.
    Figs. 7 and 8 show the complete sun gear 10 viewed in perspective on the side of the first input disk 101 (Fig. 7) and the side of the second input disk 102 (Fig. 8). Satellite gears 107a and 107b (visible by transparency in Fig. 7) are concentrically mounted and integral with the planet wheels 104a and 104b, respectively (also visible by transparency in Fig. 8). The planet gears 107a, 107b engage the intermediate wheel 106 to drive the planet wheels 104a, 104b upon rotation of the first input disk 101.
    Fig. 9 shows a sectional view of the sun gear 10 and FIG. 10 shows a view of one of the satellites 104a, 104b with its planet gear 107a, 107b. Each of the satellites 104a, 104b comprises a guide 109 in the form of a plate 110 whose periphery has a substantially smooth surface and adapted to come into mechanical contact with the periphery of the openings 108a and 108b.
    In operation, when the first input disk 101 by the board 21 of one of the barrels 20, the intermediate wheel 106 rotates the pinons of satellites 107a, 107b and satellites 104a, 104b in the opposite direction Similarly, when the second input disk 102 is rotated by the ratchet 30, an internal toothing 111 of the second input disk 102 (see FIG. 104a, 104b satellites in the same direction as the direction of rotation of the second input disk 102. The satellites 104a, 104b then drives, through the guide 109, the output disk 103 in rotation, in the same direction as the satellites 104a, 104b. The output disc 103 in turn drives the power reserve lima 22.
    The sun gear 10, according to the configuration described, may have a lower thickness than that of a conventional sun gear.
