    Description
    Technical Field [0001] The present invention relates to the field of watchmaking. It relates, more particularly, a timepiece comprising an animation device.
    STATE OF THE ART [0002] Several prior art pieces are known from the prior art, exhibiting various systems for displaying an animation. By way of example, the document EP 2 527 930 discloses a mechanical watch comprising an animation disk subjected to a jerky rotation so as to show, through a wicket made in the dial, an animation formed by a sequence of images. that presents the disc.
    JP 61-239190 discloses a watch similar to that of EP 2,527,930 mentioned above, wherein the disc is moved by means of a stepper motor.
    US 2 891 378 also discloses a mechanical watch similar to that of EP 2 527 930 mentioned above, in which the animation is formed by sequences of images that carry two disks arranged tangentially, each complete image being formed by the meeting of one of the images of each disc.
    However, all systems mentioned above, although relatively thin and compact, have one or more disks subjected to jerky rotation, which is necessary to let the animation appear through a window. Such jerky movements cause wear of the drive mechanism components, energy losses, and unpleasant noise during the animation.
    The object of the invention is therefore to provide a modular timepiece in which the aforementioned defects are at least partially overcome.
    Disclosure of the invention [0007] More specifically, the invention relates to an animated timepiece comprising a watch movement, a time display device arranged to be driven by the watch movement, and an animation device. According to the invention, the animation device comprises a praxinoscope system comprising a rotor, the latter being arranged to be rotated by a power source.
    [0008] In general terms, a praxinoscope is an animation device comprising a central portion having a plurality of mirrors, typically flat, arranged to form a generally angular and faceted wall. In front of and at a distance from these mirrors is a plurality of sequential images arranged on a substantially cylindrical wall, faceted or not, each of the images being in front of a corresponding mirror. During a rotation of the praxinoscope, the sequential images are animated, reflected in the mirrors.
    A praxinoscope rotating continuously, that is to say in a non-jerky manner, its drive mechanism can be substantially simpler than that of the prior art systems, generates comparatively less noise, and loses comparatively less energy.
    Advantageously, the rotor comprises a central portion having a plurality of mirrors arranged in a circle and inclined relative to an axis of rotation of the rotor, a peripheral portion having a plurality of images, each image being in front of a corresponding mirror, and a bridge connecting the central portion to the peripheral portion such that the central portion and the peripheral portion are mutually integral in rotation. Preferably, the bridge is transparent, the time display device being located such that it is at least partially visible through the bridge. Therefore, a compact construction can be proposed, for example with the rotational axis of the rotor coaxial with the display device.
    Advantageously, said source of energy is independent of that of the watch movement. The animation device is thus independent of the basic movement, and can not affect its function. In addition, an independent power source allows a modular construction that can be integrated into any existing movement.
    Advantageously, the praxinoscope system comprises a jumper for cooperating with a positioning cam disposed on the rotor and arranged to position the rotor in one of a plurality of predetermined angular positions when the rotor is not in rotation. Therefore, unwanted rotation of the rotor can be avoided.
    Advantageously, the energy source is a mainspring in kinematic connection with a peripheral toothing that includes the rotor, preferably via a multiplier gear.
    Advantageously, the rotor is adapted to be driven by the energy source following an action of a user on a manual actuator, for example a lever having a rack actuated by means of a button. pusher, zipper, or the like.
    Advantageously, the praxinoscope system comprises an actuating device comprising: a trigger rocker adapted to block the rotation of the rotor in a locking position of said rocker and to release the rotation of the rotor in a position of triggering said latch; an actuating wheel adapted to be pivoted by a predetermined angle in response to said action of the user, the actuating wheel being adapted to store a predetermined amount of energy in the energy source; actuation comprising an actuating cam adapted to pivot the trigger rocker between said lock position and said trip position when said predetermined amount of energy has been stored in the power source. Therefore, the animation is triggered only after said predetermined amount of energy has been stored in the power source, to ensure that there will be enough energy to perform the animation.
    Advantageously, the trigger rocker is adapted to lift said jumper when said trigger flip-flop is in said trigger position. Therefore, the jumper can position the rotor in the rest position, and release it from the trigger, thus avoiding the jumper harms the rotor rotation.
    Advantageously, the jumper is adapted to exert a restoring force on the trigger rocker tending to push the trigger rocker to said blocking position. No additional spring for the trigger rocker is required.
    Advantageously, the actuating device further comprises a locking cam in kinematic connection with the energy source and the rotor and arranged to block, at least indirectly, the rotation of the rotor, the locking cam being adapted to be locked in rotation in a predetermined position by the trigger rocker when the trigger rocker is in said blocking position. Preferably, the locking cam is adapted to be re-locked by the trip lever when said predetermined amount of energy has been consumed, which can be achieved by selecting appropriate gear ratios.
    Advantageously, the actuating mobile comprises a flexible safety cam, the safety cam being adapted not to prevent the trigger rocker from passing between the locking position and the trigger position, and to prevent the trigger flip to return to the lock position before the lock cam has rotated by a predetermined angle. Therefore, if the user releases the manual actuator too fast, immediate re-locking of the locking cam is avoided.
    Advantageously, the rotor is pivoted on a ball bearing, to reduce friction.
    The timepiece may advantageously be a wristwatch or a pocket watch.

    Embodiments of the Invention [0023] FIG. 1 schematically illustrates, and in general, a timepiece 1 according to the invention. This timepiece is, for example, a wristwatch, a pocket watch, a clock, or the like. The timepiece 1 comprises, as standard, a clockwork movement 3 provided with its own energy source, which drives a display device 5 of any type.
    The timepiece 1 further comprises an animation device 7. According to the invention, the animation device comprises a praxinoscope system 9, which comprises a rotor 11 driven by a power source, as shown in FIG. this will be described in more detail below.
    According to the most general form of the invention, the watch movement can be of any kind, for example mechanical, electromechanical, or digital, and the rotor 11 of the praxinoscope system 9 can share a source of energy with the watch movement 3, or alternatively the watch movement 3 and the praxinoscope system 9 may each have its own independent source of energy. Furthermore, it should be noted that, in general, the source (s) of energy may be electrical (s) or mechanical (s), or a combination of a source of mechanical energy with a source of energy. 'electric energy.
    Figs. 2 and 3 illustrate a particular embodiment of a praxinoscope system 9 for a timepiece according to the invention, seen from above in FIG. 2, that is to say on the side where the animation is visible, and seen from below in FIG. 3, that is to say on the bottom side, in the rest position. This embodiment of the praxinoscope system 9 is presented in fully mechanical form, which has its own source of mechanical energy, that is to say its own motor spring. The praxinoscope system 9 is constructed in a modular manner, independently of the clockwork movement. It is therefore likely to be integrated into any timepiece.
    The praxinoscope system 9 comprises a rotor 11, intended to be pivoted on an element of the frame of the timepiece 1 by means of a ball bearing (not shown), to minimize friction during the rotation of the rotor 11. The rotor 11 comprises a central portion 13 having a plurality of mirrors 15 arranged in a circle and slightly inclined with respect to the axis of rotation of the rotor 11. In this case, the central portion 13 has twelve mirrors 15, but the number of mirrors can be chosen according to the needs of the watchmaker. The rotor 11 further comprises a peripheral portion 17 having an inner wall 19 provided with a plurality of images (not shown), each image being positioned in front of a corresponding mirror 15. The peripheral portion 17 is connected to the central portion 13 by a bridge 16, which is advantageously transparent (for example sapphire, glass, transparent plastic, etc.) in order to reveal display means (see FIGS. 12), such as needles 5a, 5b, located under the rotor 11. The principle of animation of a praxinoscope is well known, and need not be described in more detail.
    The central portion 13 has a housing 14 in which can be housed for example a decorative element such as a jewel, any display, a mirror assembly comprising two opposite concave mirrors defining a cavity within which is finds an object, one of the concave mirrors being pierced with an opening revealing said object (see below), or the like.
    The rotor 11 comprises a peripheral toothing 21 which serves to drive the rotor 11 by an actuating device 23. The peripheral toothing 21 is also kinematically connected, via an intermediate mobile 24, with a speed regulator 25. , the latter comprising an inertia flywheel 27. The speed regulator 25 can be of any type, and could alternatively be arranged as a sub-element of the actuating device 23.
    When the rotor 11 does not rotate, it is positioned by a jumper 29 provided with a jumper spring 29a and a roller 31 on one of its ends. The jumper 29 is movable between a stop position, in which the roller 31 cooperates with a positioning cam 33 arranged peripherally around the rotor 11, and which has a plurality of notches 35. These notches 35 are arranged in such a way that the rotor 11 is stopped in one of a plurality of predetermined angular positions, for example with one of the mirrors parallel to the axis 9 h-3 h of the timepiece.
    When actuating the praxinoscope mechanism, the jumper 29 is raised by a trigger rocker 30 against the effect of the jumper spring 29a, so that the roller 31 is moved away from the positioning cam 33, and that the rotor 11 can rotate freely, as will be described in more detail later. The jumper spring 29a therefore also serves to push the trigger rocker 30, but it is also possible to use an additional spring for the same purpose.
    FIG. 4 illustrates a portion of the actuating device 23 in exploded view. The actuating device comprises a manual actuating member 37, here represented as a push lever pivoted at 39 on an element of the frame of the timepiece 1 (not shown) and comprising a rack 41 at its free end. The manual actuating member 37 is pushed towards its rest position by means of a spring 43, and its trajectory is limited by a stud 45 integral with an element of the frame, located inside a slot 47 operated in manual actuator 37. Alternatively, the manual actuator 37 could be constituted for example by a pull.
    The manual actuating member 37 interacts with an actuating wheel 49 to start the operation of the praxinoscope device 9.
    The actuating mobile 49 comprises a pinion 51 meshing with the rack 41, an actuating cam 55, a drive wheel 54, and a retractable safety cam 57 sandwiched between the drive wheel 54 and the actuating cam 55. The retractable safety cam 57 is connected to the actuating cam 55 via a spring 56. The actuating cam 55 and the retractable safety cam 57 interact with a first spout 32 that includes the tripping lever 30, as will be described in more detail below. The drive wheel 54 has in the illustrated case a partial toothing, but it is also possible that the drive wheel 54 has a complete toothing.
    The drive wheel 54 meshes with a wheel 61 of a motor assembly 59. The motor assembly 59 comprises a cylinder 65 in which is housed a motor spring 67, the outer end of which is in connection with a drum 69, conventionally. The drum 69 is provided with a burr gear 70 which interacts with a drum pawl 72, which prevents the drum 69 from disarming.
    The inner end of the motor spring 67 is connected to a barrel axis 63, which is integral in rotation with the wheel 61.
    The barrel axis 63 is integral in rotation with a ratchet wheel 71, which is positioned by a pawl 73, the latter being secured in rotation with a barrel wheel (see below). At each full activation of the manual actuator 37, a predetermined amount of energy is stored in the motor spring 67 by pivoting the barrel axis 63 at a predetermined angle. This predetermined amount of energy represents the energy required to perform once the course of the animation, which could represent one or more turns of the rotor 11. For example, if a half-turn of the mainspring 67 is used to perform animation, the barrel axis turns a half turn when the animation is activated.
    In the illustrated embodiment, if the user actuates the manual actuator 37 incompletely, the ratchet wheel 71 has not been rotated sufficiently to store said predetermined amount of energy in the spring motor 67, the animation is not triggered (see below) and the manual actuator 37 remains in its partially actuated position. Therefore, an overload of the mainspring spring 67 by successive pressures on the manual actuator 37 is avoided.
    The pawl of the ratchet wheel 71 is rotatably connected to a wheel 75. This wheel 75 is kinematically connected to a multiplier wheel 77 (see FIGS 2 and 3), and meshes via an intermediate wheel 76 with a first mobile 79 of the multiplier wheel 77.
    The first mobile 79 of the multiplier wheel 77 comprises a locking cam 81 which has a notch 83 which interacts with a locking nose 85 that includes the tripping lever 30. When the locking nose 85 is in the notch 83, the first mobile 79 is blocked and can not rotate. By raising the tripping lever 30, the locking nose 85 exits the notch 83, and the first mobile 79 is free to rotate under the effect of the motor spring 67, thus driving the rotor 11 in rotation through the multiplier wheel 77.
    The operating sequence of the praxinoscope system 9 will now be described with reference to FIGS. 5 to 10. In order to avoid overloading these figures, only the reference signs of the described and visible components have been shown here.
    FIG. 5 illustrates the praxinoscope system 9 in its rest position. In this position, the manual actuating member 37 is in its rest position, and the actuating cam 55 is in its angular position of rest, turned completely clockwise. The first nose 32 of the actuating lever 30 is in contact with a portion of the lower radius 55a of the actuating cam 55, and the actuating lever 30 is in its rest position. Therefore, the jumper 29 interacts with a notch 35 (not visible in Fig. 5) to position the rotor 11, and the lock nose 85 of the operation rocker 30 is in the notch 83 of the cam blocking 81. The multiplier gear wheel 77 is thus blocked. Note that the end of the retractable safety cam 57 is visible in protrusion towards the end of the portion of the lower radius 55a of the actuating cam 55, considered clockwise.
    FIG. 6 illustrates the praxinoscope system 9 at an incomplete pressure on the manual actuator 37, not yet sufficient to store said predetermined amount of energy in the mainspring 67. In response to the application of a force F on the manual actuator 37, the actuator 49 is rotated anti-clockwise (with reference to the view of Fig. 6). The first spout 32 of the actuating lever 30 slides along the portion of the lower radius 55a of the actuating cam 55, while the wheel 61 of the motor assembly 59 is rotated clockwise by the spur wheel. drive 54 of the actuator 49, thus winding the motor spring 67. In doing so, the actuating lever 30 remains in its rest position. Note also that the first spout 32 pushes the end of the retractable safety cam 57 to pivot and retract under the actuating cam 55.
    FIG. 7 illustrates the praxinoscope system 9 when the manual actuator 37 has been fully pushed. The transition between the portion of the lower radius radius 55a and a portion of the upper radius 55b of the actuating cam 55 causes the actuating lever 30 to rotate counterclockwise, while the predetermined amount of energy has been stored. in the mainspring 67. The retractable safety cam 57 is released, and returns to its rest position.
    Simultaneously, the locking nose 85 leaves the notch 83 that includes the locking cam 81, thus releasing the multiplier wheel 77, which is free to rotate under the effect of the motor spring 67 via the In addition, the actuating lever 30 lifts the jumper 29, which releases the rotor 11. In doing so, the multiplier wheel 77 is released exclusively when said predetermined amount of energy has been stored in the motor spring 67, avoiding and the motor spring 67 is gradually overloaded or insufficiently loaded after several activations of the praxinoscope system 9.
    Following the release of the multiplier gear 77, the rotor 11 rotates anti-clockwise, and displays the animation. The speed of the rotor 11 is regulated by the speed controller 25 in a known manner.
    FIG. 8 illustrates the praxinoscope system 9 a few moments after the activation of the animation, the manual actuator 37 having been released.
    The first mobile 79 of the multiplier wheel 77 has rotated slightly in the clockwise direction, angularly moving the notch 83 of the locking nose 85. To prevent the locking nose 85 from falling immediately into the notch 83, the first nose 32 of the tripping lever 30 comes into contact with the retractable safety cam 57, which protrudes from the actuating cam 55 adjacent to the portion of the upper radius 55b to a radius intermediate the portion of the lower radius 55a and the portion of the upper radius 55b. This prevents the locking nose 85 from coming into contact with the locking cam 81 before the notch 83 has been moved by a sufficient angle to prevent the locking nose 81 from reengaging there, which would have to block the triggering of the animation while the mainspring 67 has been wound.
    FIG. 9 illustrates the praxinoscope system 9 during the animation. The rotor 11 continues to rotate under the effect of the mainspring 67. The manual actuating member 37 returns to its rest position under the effect of its spring 43 in combination with the effect of the wheel 61, which is driven in the anti-clockwise direction (relative to the view of FIG 9) by the rotation of the barrel axis driven by the interaction of the pawl 73 with the ratchet wheel 71, the latter being rotationally secured in this direction of rotation with the wheel 75 which is turning in the same direction. The first nose 32 of the actuating lever 30 is in front of the lower radius portion 55a of the actuating cam 55, but can not come into contact with the latter by means of the locking nose 85 of the rocking lever. 30, which is in contact with the surface of the locking cam 81 under the effect of the jumper spring 29a (see Fig. 3), while the locking cam 81 continues to rotate.
    When the locking cam 81 has performed a complete revolution, the locking nose 85 of the actuating lever 30 falls into the notch 83, thus blocking the multiplier wheel 77. Therefore, the actuating lever 30 rotates clockwise until its first protrusion 32 comes into contact with the portion of the lower radius 55a of the actuating cam 55. Simultaneously, the actuating lever 30 returns the jumper 29 to its off position thus positioning the rotor 11 as described above. Following these actions, the praxinoscope system 9 is found in its rest position as illustrated in FIG. 5. The gear ratios are arranged such that the locking cam 81 has made a full revolution when said predetermined amount of energy has been discharged from the mainspring 67. If for example the mainspring 67 is wound by a when the mechanism is actuated, the locking cam 81 has made a complete revolution when the mainspring 67 has taken a half turn. Therefore, the mainspring 67 can not be raised too much, and can not unroll too much, without the need for a torque limiting device or the like. Naturally, a different number of notches 83 could be provided on the locking cam 81, the locking cam rotating from one notch to the next for each activation of the animation.
    Note that, although the blocking multiplier gear 77 by the interaction of the locking nose 85 and the notch 83 is sufficient to stop the rotor 11, the gear wheel 77 has a relatively high clearance, which in turn As a result, stable positioning of the rotor is difficult to achieve by this blocking alone. For this reason, jumper 29 is useful for precisely stopping and positioning rotor 11. If such positioning is not imperative, jumper 29 can be omitted.
    Other simplifications of the actuating device 23 are conceivable for less demanding applications. For example, the manual actuating member 37 could be in direct kinematic connection with the rotor 11, so that pressure on the manual actuating member drives the rotor 11 in rotation, the inertia of the rotor 11 and the speed controller 25 ensuring that the rotor 11 continues to rotate for a time. This extremely simple solution would advantageously have a unidirectional coupling mechanism, so that the rotor 11 can continue to rotate once the manual actuator 37 has been released. As a result, all other components of the actuator 23, and possibly also the speed controller 25, can be omitted. In this case, the energy source is the user who actuates the manual actuating member 37.
    Again alternatively, the rotor 11 may be driven by an electric motor, the manual actuating member 37 being an electrical switch adapted to activate said motor for a predetermined period of time.
    In another variant, the driving force for the rotor rotation 11 can come from the motor spring of the watch movement, for example by means of a differential gear acting as a torque distributor. An example of the application of this concept to a bell watch is disclosed in EP 1 925 995. The necessary modifications to the actuating device 23 driven by this variant are obvious to those skilled in the art. Figs. 10 to 12 illustrate a particular variant of a timepiece 1 incorporating a watch movement 3, a display device 5 driven by the watch movement 3, and a praxinoscope mechanism 9 corresponding to that disclosed. in figs. 2 to 9. For reasons of clarity, the housing elements have not been shown here.
    In the present case, the watch movement 3 comprises a recess which houses the praxinoscope mechanism 9. The display device 5 is arranged coaxially with the axis of rotation of the rotor 11, the needles 5a, 5b that the display device 5 is arranged under, and being visible through, the transparent bridge 16 of the rotor 11.
    In the embodiment shown, the housing 14 that includes the central portion 13 of the rotor 11 receives an optical device 90 comprising an assembly of concave mirrors mounted face to face, similar to that described in the document JP 59-075 182 Inside this optical device is a decorative object 91, such as a jewel, integral with the optical device 90, which appears "floating" above a central opening 92 in the upper mirror, which reveals the said object 91. As an alternative, the decorative object 91 could be a display of any type, kinematically related to the watch movement 3.
