Description

Technical area

The present invention relates to an animated part for the field of jewelery or jewelery comprising a frame housing a source of mechanical energy, capable of storing mechanical energy intended to supply an animation device, an external control device arranged to supply mechanical energy to the mechanical energy source in response to its actuation by a user following a first predefined rotational movement, and a locking mechanism arranged to be able to present a first state, in which it locks the source of mechanical energy, to store mechanical energy for an indefinite period, and a second state in which it releases the source of mechanical energy to enable it to supply mechanical energy to the animation device.

[0002] According to a preferred embodiment of the present invention, the animated piece is a ring.

State of the art

[0003] Various ornamental objects comprising an animation device have been known for a long time.

By way of illustration, US Patent 3,247,683 describes such an object comprising a box housing a mechanical energy source arranged to control the rotation of a cam acting on a horse-shaped figurine to simulate a galloping movement. A crown rod is arranged under the case to allow a user to charge the mechanical energy source, while a movable locking rod is arranged on the side of the case to allow the user to activate the animation on demand.

[0005] Some prior embodiments relate to pieces of jewelery or jewelery for which the overall size of the object is a critical parameter to be taken into account.

[0006] US Pat. No. 1,025,447 presents a piece of jewelry or jewelry comprising a case housing an animation device driven from the mechanical energy stored in a mainspring. The barrel comprises a shaft extending outside the case and carrying a gripping member to allow the barrel spring to be loaded by rotation of the shaft. The mechanical energy is transmitted from the barrel spring to an animated member, a portion of which is located outside the case, via a gear train and a lever escapement allowing the unwinding speed to be regulated. of the barrel spring. The anchor escapement also fulfills the role of a locking mechanism, to some extent, sufficient shock to start the movements of the anchor to activate the animation. Such a solution makes it possible to limit the number of gripping members extending outside the case, which is more favorable from the point of view of the decorative appearance of the object, especially since the latter is intended to be concealed in a garment or accessory to reveal only the animated organ. However, the planned mode of actuation is not necessarily satisfactory due to a certain lack of predictability and the fact that it may seem strange, even not very reassuring, for a user to have to apply a shock to a piece of jewelery or jewelry, probably expensive, to run its animation. In addition, the regulation and locking mechanism as described has a not insignificant bulk, which is not desirable in the production of a piece of jewelry or portable jewelry.

[0007] Patent CH 332246 describes a compact construction suitable for producing a brooch or a ring comprising an animation device. A decorative component of the object discreetly fulfills the function of an external control device making it possible to recharge a source of mechanical energy, prior to the activation of the animation, by driving a pinion arranged to roll on a toothing fixed. This construction has no locking mechanism of the animation device which is therefore actuated as soon as the source of mechanical energy is sufficiently charged.

Disclosure of Invention

[0008] A main object of the present invention is to propose a construction of an animated part for the field of jewelry or jewelery comprising a source of mechanical energy, intended to supply an animation device, as well as a a locking mechanism for storing mechanical energy in the mechanical energy source indefinitely until a user voluntarily activates the animation device.

[0009] To this end, the present invention relates more particularly to an animation part of the type mentioned above, characterized in that the external control member is also arranged to act on the locking mechanism and cause it to pass from its first state to its second state in response to an actuation of the external control member by the user following a second predefined rotational movement different from the first rotational movement.

[0010]Preferably, the present invention relates to a wearable animation part on the body, such as a ring, a bracelet, a necklace, or on a piece of clothing or an accessory, such as a brooch for example, which can be worn directly on a piece of clothing, such as a dress or a scarf, or else on a bag, and which fulfills the function of an ornamental accessory.

[0011] Thanks to these characteristics, it is possible to produce an animated piece for the field of jewelery or jewelry that meets high aesthetic criteria while implementing a simple and practical animation device. to actuate. Indeed, the fact of using one and the same external control device to carry out two different operations makes it possible to maintain mystery and a high level of discretion as to the technical function of the piece of jewelry or jewelry according to the present invention, without sacrificing ergonomics. In addition, the fact of having concentrated two functions on the same control member makes it possible to maintain good compactness of the construction, which makes it particularly suitable for preferred implementation in the form of a ring.

[0012] According to a preferred embodiment, the external control member is rotatable between a rest position and, on the one hand, a winding position that it is likely to reach following the implementation of the first rotational movement and, on the other hand, an actuation position that it is likely to reach following the implementation of the second rotational movement. In addition, in this case, the animated part advantageously comprises an elastic return member arranged to act on the external control member and tend to bring it back to its rest position.

[0013] Furthermore, it can be provided that the mechanical energy source comprises a spring having a free end capable of being moved with reference to the frame, to allow a variation of the mechanical energy stored by the spring, the free end being capable of having a kinematic connection with the animation device, and that the external control member is arranged to actuate a spring-loading member in response to the implementation of the first rotational movement.

[0014] In this case, the locking mechanism preferably comprises a locking rocker arranged to at least indirectly lock the free end of the spring, in a locking position, when the external control member is pivoted into its winding position, and an elastic return member arranged to act on the locking rocker and tend to position it in its locking position.

[0015] One can then advantageously further provide that the locking rocker is capable of cooperating with the load member to ensure the locking of the free end of the spring by means of the load member.

[0016] According to a preferred embodiment variant, provision may be made for the free end of the spring to be able to be connected to the driving device via the load member.

[0017] In this case, provision can also be made for the load member to comprise a set of teeth arranged in engagement with a unidirectional transmission wheel set intended to transmit at least part of the mechanical energy stored in the spring to the device for animation when the external actuator is rotated into its actuating position.

[0018] In general, provision can be made for the external control member to be arranged in such a way that the first and second rotational movements have a common axis of rotation X but opposite directions of movement.

[0019] In this case, provision can be made for the external control member to be arranged, when it is pivoted into its actuating position, to actuate a control lever acting on the locking lever, when there is has one, to move it away from its locking position and release the free end of the spring.

[0020] According to a variant embodiment, provision may be made for the external control member to be arranged in such a way that the first and second rotational movements have separate axes of rotation X and Y, preferably perpendicular.

[0021] In this case, it is conceivable to also provide for the external control member to be integral with a first X-axis ring having a mechanical connection with a second X-axis ring, integral with the frame, such as that the first ring is capable of pivoting along the X axis with reference to the second ring to pass from the rest position to the winding position, and the first ring is capable of pivoting along the Y axis with reference to the second ring to pass from the rest position to the actuation position.

[0022] It is also possible to provide then that the first ring be arranged to act on a tenon, so as to move it in a direction substantially parallel to the axis X, when it pivots along the axis of rotation Y , the tenon being arranged to move the locking rocker away from its locking position and release the free end of the spring when the external control member is pivoted into its actuating position.

[0023] In general, provision can be made for the part according to the invention to comprise a speed regulator arranged to regulate the speed of the animation device.

Embodiment(s) of the Invention

[0025] Figure 1 shows a schematic view exposing the general principle of implementation of an animation part for the field of jewelry or jewelry according to a preferred embodiment of the invention, that is to -say being in the form of a ring 1, according to two preferred embodiments. Indeed, as will emerge from the remainder of the description, the advantageous properties of the construction according to the present invention make it particularly suitable for implementation in the form of a ring but, of course, other parts of jewelry or portable jewelry, in particular more cumbersome, can be made without departing from the scope of the invention.

More precisely, FIG. 1 comprises an illustration of small dimensions, at the top left, of the assembled ring 1 as well as an illustration in exploded perspective, in the center, of two preferred embodiment variants likely to be implemented. artwork in ring 1.

[0027] Initially, the general structure of the ring 1 will be presented in relation to Figure 1.

The ring 1 comprises a main body 2 having an annular opening 4 through which the ring 1 is intended to be worn on a finger of a user, in a conventional manner.

[0029] The main body 2 comprises a housing 6 having a shape of revolution of axis X, perpendicular here to the axis of the annular opening 4, in a non-limiting manner. The housing 6 comprises an annular rim 8 and defines a frame for the other components of the ring, which will now be described and which can be divided into two groups: components of a motor module 100 or 200, depending on the variant embodiment , and components of a module or animation device 1000, all these components being enclosed on the frame by a covering element 10, here presenting the shape of a flower corolla and acting as a cover in cooperation with housing 6.

The animation module or device 1000 will be briefly described here by way of non-limiting illustration, it being understood that it may have a very large number of different possible embodiments without departing from the scope of the invention.

The animation device 1000 comprises a plate 1002 intended to be secured to the main body 2, by any known suitable means, with the interposition of a motor module 100 or 200.

The plate 1002 is surmounted by an auxiliary plate 1004 to allow the assembly between stones of the constituents of a drive mechanism of different organs whose movements define an animation.

More specifically here, the animation device 1000 comprises a cam 1006, non-circular and / or eccentric, intended to be carried by a shaft of the motor module 100 or 200 to play the role of input member and arranged to cooperate with a feeler 1008. The latter is carried by a rocker 1010 also carrying a rack 1012 arranged in engagement with a first mobile display 1014, itself in engagement with an adjacent second mobile display 1016, in such a way that the two display mobiles rotate simultaneously but in opposite directions. The shape of the cam 1006 makes it possible to give an impression of random movement to the whole.

[0034] Each of the display mobiles 1014 and 1016 comprises an axis, which passes through the auxiliary plate 1004 as well as a dial 1018, and carries a butterfly wing 1020, which can advantageously be made of a precious stone. The dial 1018 carries an additional element 1022 representing the body of the butterfly in reference to which the wings flap when the animation is activated.

The trim element 10 is then engaged around the motor modules 100 or 200 and animation 1000 to enclose and protect them. This comprises a central cylinder 12 provided with four holes 14 making it possible to make the covering element 10 integral with the main body 2 by means of screws 16.

A protective glass (not shown) can advantageously be provided to close the free face of the cylinder 12 and protect the components of the animation device 1000.

The two preferred embodiments of the motor module 100 (FIGS. 2 and 3a to 3d) and 200 (FIGS. 4 and 5a to 5d) will now be described in detail.

[0038] Figure 2 shows an exploded perspective view of the motor module 100 according to the first preferred embodiment, some components of which are more clearly visible in the exploded view of Figure 1, also useful for understanding since it corresponds to an angle of view opposite to that of figure 2.

In this first preferred embodiment variant, provision is made for the external control member, here the covering element 10, to be able to be actuated according to a first predefined rotational movement to charge a source of mechanical energy. of the ring 1, then following a second predefined rotational movement, different from the first, to actuate the animation device. More specifically, this first preferred embodiment provides that the two predefined rotational movements are performed along one and the same axis of rotation X, but in opposite directions of rotation.

[0040] To this end, the ring 1 comprises a control ring 102 intended to be integral with the covering element 10 and assembled at least indirectly to the main body 2 so as to be able to pivot with reference to the latter according to the X axis between a rest position and, on the one hand, a winding position and, on the other hand, an actuation position.

[0041] Abutment members can advantageously be provided to define the winding and actuation positions. By way of example, the control ring 102 here comprises a pad 104 intended to cooperate with an abutment surface (not visible) integral with the main body 2 of the ring 1, in the winding position and/or in the position actuation.

[0042] It will be noted that the control ring 102 is advantageously subjected to the action of at least one elastic return member (not shown) arranged so as to oppose the actions of the user on the element of trim 10 to return the control ring 102 to its rest position. Such an elastic return member could for example be adapted to be able to work both in elongation and in compression, preferably in a direction close to a direction tangent to the control ring 102. Alternatively, provision could be made for placing at least one substantially radial elastic strip, one end of which would be secured to the control ring 102, while the other end would be secured to the main body 2. A person skilled in the art will not encounter any particular difficulty in putting implements one or more suitable return members, according to its own needs and without departing from the scope of the present invention.

The control ring 102 working in both directions of rotation, according to this first preferred embodiment of the invention, its rest position corresponds to an intermediate position between the two directions of rotation, respectively the winding direction and the direction of release or actuation, this intermediate position being able to be defined either by zero winding of an elastic return member (spring at rest between compression and elongation) or by a configuration of equilibrium between two antagonistic elastic return, either by a physical indexing device, such as a ball or cylinder pawl, a jumper or any other device cooperating with an indexing position 105 on the control ring, such as an index, for example, a hollow, etc.

The control ring 102 has an internal cutout 106, arranged to cooperate with a control sensor 108 so as to make it pivot according to the angular orientation of the control ring 102.

The control sensor 108 is integral with a control lever 110 comprising a beak 112 arranged to act on a rake 114 and rotate it clockwise in the view of Figure 2.

The rake 114 has a lug 116 positioned bearing against a free end of a spring 118 in such a way that the rotation of the rake 114 in the clockwise direction of rotation causes a load on the spring 118 which can thus store mechanical energy to be restored later.

[0047] The ring 1 further comprises a locking mechanism intended to allow storage of mechanical energy in the spring 118 for an indefinite period, until the user performs a predefined action to release it and activate the 'animation. The locking mechanism comprises a locking rocker 120 made here in one piece with an elastic return member 122 exerting on it a force tending to push it back in the direction of the rake 114, in a locking position. A notch 124 of the rake 114 is in fact intended to cooperate with a notch 126 of the locking rocker 120 in the locking position, in such a way that the rake 114 cannot rotate in the direction of counter-clockwise rotation on the view. of Figure 2.

Furthermore, the toothing of the rake 114 is arranged in permanent engagement with a pinion 128 forming part of a unidirectional transmission mobile, the latter also comprising a spring 130 and a wheel 132. The pinion 128 has a barrel 134 of non-circular section and engaged in a hole of complementary shape of the spring 130, so that these two elements are integral in rotation. The free end of the spring 130 is intended to cooperate with notches 136 made in the wheel 132 to drive the latter in rotation when the pinion 128 rotates in the clockwise direction of rotation in the view of FIG. 2. When the pinion 128 rotates in the anti-clockwise direction of rotation in the view of FIG. 2, the free end of the spring 130 slides on the notches 136 of the wheel 132 which is therefore not driven.

It appears from the above explanations that the wheel 132 is not rotated when the spring 118 is loaded, while it is rotated when the spring 118 discharges.

The wheel 132 is in kinematic connection with an output wheel set 140 via a connecting wheel set 142 preferably shaped in such a way that the speed of rotation of the wheel 132 is multiplied and the output wheel set 140 spins much faster than wheel 132.

[0051] Furthermore, the output mobile 140 also has a kinematic connection, via a gear train 144, with an inertial brake 146 to regulate its speed of rotation, and therefore that of the cam 1006 of the animation module that is meant to wear.

[0052] The operation of the ring 1 according to the first preferred embodiment will now be described on the basis of the above elements as well as Figures 3a to 3d which represent perspective views of the motor module 100, at different times of a complete sequence, comprising an illustration of the configuration at rest (FIG. 3a), of the configuration in the winding position of the spring 118 (FIGS. 3b and 3c, illustrating two views from opposite viewing angles), followed by the configuration during actuation of an animation (FIG. 3d), the covering element 10 and the animation module 1000 not being shown for greater clarity.

[0053] Figure 3a shows the motor module 100 while the spring 118 is disarmed.

[0054] Starting from this configuration, a user can drive the covering element 10 in rotation in the clockwise direction, in the view of FIG. 3a, to drive the control ring 102 in the same direction, and therefore also the control sensor 108 via cutout 106.

The control lever 110 is then driven in the same direction of rotation and acts on the rake 114 by its beak 112 to rotate it clockwise and load the spring 118.

When the amplitude of rotation of the trim element 10 is sufficient, the motor module 100 goes into the winding position, as illustrated in Figures 3b and 3c.

In this position, the notches 124 of the rake 114 and 126 of the locking rocker 120 are positioned opposite each other and are engaged, the rake 114 thus being locked in the winding position.

The spring 118 is then charged with a predefined quantity of mechanical energy, which it can store as long as the user does not take any other action on the covering element 10.

When the corolla is released by the user, the control ring 102 resumes its rest position under the effect of the action of its elastic return member. The control ring 102, the control sensor 108 and the control lever 110 thus return to their position as illustrated in FIG. 3a.

[0060] Starting from the rest position, a rotation of the corolla 10 and therefore of the control ring 102 in the direction of counter-clockwise rotation in the view of FIG. 3d has the effect of bringing into contact a steep wall 150 of the cutout 106 with the control probe 108. A further rotation of the control ring 102 has the effect of causing the control probe 108 to pivot in the direction of counter-clockwise rotation as illustrated in the view of FIG. 3d.

The control lever 110 then rotates in the same direction of rotation and has an unlocking surface 152 facing an unlocking feeler 154 located at the free end of the locking rocker 120.

[0062] This movement causes rotation of the locking rocker 120 which deviates from its locking position, thus releasing the rake 114 which begins to pivot in the direction of counter-clockwise rotation under the effect of the action of the spring 118 which can release the previously stored mechanical energy.

The rake 114 then drives the pinion 128 in rotation in the direction making it possible to simultaneously drive the wheel 132 and therefore to drive the animation device via the output mobile 140, until the rake 114 reaches its rest position, in abutment against the control lever 110, as shown in Figure 3a.

[0064] The control ring 102 also resumes its rest position as illustrated in Figure 3a, as well as the control sensor 108 and the control lever 110, when the user releases the corolla 10 and that the corresponding elastic return member can fulfill its role.

[0065] Thus, the corolla 10 plays the role of an external control member capable of being actuated by a user, following a first predefined rotational movement, to load the spring 118 with mechanical energy. The corolla 10 can also be actuated later by the user, following a second predefined rotational movement, to act on the locking mechanism and release the spring 118 to enable it to supply its mechanical energy to the animation device 1000.

[0066] Figure 4 shows an exploded perspective view of the motor module 200 according to the second preferred embodiment, some components of which are more clearly visible in the exploded view of Figure 1, also useful for understanding since it corresponds to an angle of view opposite to that of figure 4.

In this second preferred embodiment variant, provision is made for the external control member, here the covering element 10, to be able to be actuated according to a first predefined rotational movement to charge a source of mechanical energy. of the ring 1, then following a second predefined rotational movement, different from the first, to actuate the animation device. More specifically, this second preferred embodiment provides that the two predefined rotational movements are carried out along separate axes of rotation X and Y, preferably perpendicular.

[0068] To this end, the ring 1 comprises a control ring 202 (illustrated in Figures 5a to 5d) intended to be secured to the covering element 10 and assembled indirectly to the main body 2 so as to be able to pivot in reference to the latter, on the one hand, along the X axis between a rest position and a winding position and, on the other hand, along the Y axis between the rest position and an actuation position.

[0069] Abutment members can advantageously be provided to define the winding and actuation positions. By way of example, the control ring 202 here comprises a pad 204 intended to cooperate with an abutment surface (not visible) integral with the main body 2 of the ring 1, in the winding position and/or in the position actuation.

[0070] As in the first preferred embodiment, the control ring 202 is advantageously subjected to the action of at least one elastic return member (not shown) arranged to oppose the actions of the user on the trim element 10 to return the control ring 202 to its rest position.

The control ring 202 has an internal cutout 206, arranged to cooperate with a control sensor 208 so as to make it pivot according to the angular orientation of the control ring 202.

[0072] The control sensor 208 is integral with a control lever 210 comprising a beak 212 arranged to act on a rake 214 and cause it to rotate clockwise in the view of Figure 4.

The rake 214 has a lug 216 positioned in abutment against a free end of a spring 218 in such a way that the rotation of the rake 214 in the clockwise direction of rotation causes a load on the spring 218 which can thus store mechanical energy to be restored later.

[0074] The ring 1 further comprises a locking mechanism intended to allow storage of mechanical energy in the spring 218 for an indefinite period, until the user performs a predefined action to release it and activate the 'animation. The locking mechanism comprises a locking rocker 220 made here in one piece with an elastic return member 222 exerting on it a force tending to push it back in the direction of the rake 214, in a locking position. A notch 224 of the rake 214 is in fact intended to cooperate with a notch 226 of the locking rocker 220 in the locking position, in such a way that the rake 214 cannot turn in the direction of counter-clockwise rotation on the view. of Figure 4.

Furthermore, the toothing of the rake 214 is arranged in permanent engagement with a pinion 128 forming part of a unidirectional transmission wheel set, as in the first preferred embodiment variant.

The components located between the pinion 118 and the animation module 1000 can be repeated identically with respect to those described in relation to the first preferred embodiment variant, they will therefore not be described again for the sake of of conciseness.

In general, a particular construction can be provided to ensure a connection of the control ring 202 to the main body in such a way that it can pivot along the perpendicular axes of rotation X and Y.

More specifically, provision can be made for the control ring 202 to be secured to a first ring 230 of axis X assembled with a second ring 232, also of axis X, by means of a mechanical connection. particular allowing: that the first ring 230 can pivot along the axis of rotation X with reference to the second ring 232, between a rest position and a winding position, and that the first ring 230 can pivot along the axis of rotation Y with reference to the second ring 232, between the rest position and an actuation position.

A part of the first ring 230 has been masked in FIG. 4 to make visible the nature of the mechanical connection implemented between the two rings 230 and 232, according to this preferred, non-limiting embodiment.

The first ring 230 carries four radial fingers 234 engaged in an outer peripheral groove 236 of the second ring 232, to define a guide for the first ring 230 when it pivots with reference to the second ring 232 along the axis of X rotation.

Furthermore, two channels 238 are formed in the second ring 232 in a direction parallel to the axis of rotation X, being diametrically opposed. These two channels 238 make it possible to mount the first ring 230 on the second ring 232, by first inserting two opposite fingers 234 into the channels 238 then, after a rotation of a quarter turn, by inserting the other two 234 fingers in 238 channels.

When the control ring 202 is in its rest position, as shown in Figure 4, two fingers 234 of the first ring 230 are positioned in the channels 238, which allows to define a guide of the first ring 230 when it pivots with reference to the second ring 232 along the axis of rotation Y. Thus, the channels 238 only allow triggering of the mechanism when the control ring 102 is in its rest position, thus mitigating the risk of release following an unsuitable angle of rotation. This security is therefore achieved by the relative positions of the rings 230 and 232 between them.

To ensure the return of the control ring 202 to its rest position between two actions by a user, at least one elastic return member (not shown) could for example be arranged between the first and second rings 230, 232 to be able to work both in elongation and in compression, preferably in a direction close to a direction tangent to the control ring 202. Alternatively, provision could be made for the placement of at least one elastic finger, preferably in the least two, substantially radial and of which a first end would be integral with the first ring 230, while the other end would be integral with the second ring 232. Such an elastic finger would make it possible to apply a return force to the first ring 230 which whatever the nature of its rotation, along the X axis or along the Y axis. A person skilled in the art will not encounter any particular difficulty in implementing one or more suitable return members, according to its own needs and without departing from the scope of the present invention. Finally, to use an indexing of the rest position along the Y axis, the person skilled in the art will have no difficulty in using an appropriate indexing member such as a jumper, a ball pawl or cylinder, etc. mounted on one or the other of the rings 230, 232 and cooperating with an appropriate indexing geometry (index, hollow, etc.) made on the other of the two rings 230, 232.

[0084] The operation of the ring 1 according to the second preferred embodiment will now be described on the basis of the above elements as well as Figures 5a to 5d which represent perspective views of the motor module 200, at different times of a complete sequence, comprising an illustration of the configuration at rest (FIG. 5a), of the configuration in the winding position of the spring 218 (FIG. 5b, corolla 10 under stress, and FIG. 5c, corolla 10 released), followed by the configuration during actuation of an animation (FIG. 5d), the covering element 10 and the animation module 1000 not being represented for greater clarity.

[0085] Figure 5a shows the motor module 200 while the spring 218 is disarmed.

[0086] Starting from this configuration, a user can drive the covering element 10 in rotation in the clockwise direction, in the view of FIG. 5a, to drive the control ring 202 in the same direction, and therefore also the control probe 208 via cutout 206.

The control lever 210 is then driven in the same direction of rotation and acts on the rake 214 by its beak 212 to make it pivot clockwise and load the spring 218.

[0088] When the amplitude of rotation of the cover element 10 is sufficient, the motor module 200 switches to the winding position, as illustrated in FIGS. 5b and 5c.

In this position, the notches 224 of the rake 214 and 226 of the locking rocker 220 are positioned opposite each other and are engaged, the rake 214 thus being locked in the winding position.

The spring 218 is then charged with a maximum of mechanical energy, which it can store as long as the user does not take any other action on the covering element 10.

When the corolla is released by the user, the control ring 202 returns to its rest position under the effect of the action of its elastic return member. The control ring 202, the control sensor 208 and the control lever 210 thus return to their position as illustrated by the passage from FIG. 5b to FIG. 5c.

[0092] Starting from the rest position, a new rotation of the corolla 10 and therefore of the control ring 202, this time along the axis of rotation Y to move it into the actuating position, should make it possible to release the mechanical energy stored in the spring 218.

To this end, the motor module 200 comprises an unlocking pin 252 arranged so as to be able to move substantially in translation in a direction substantially parallel to the axis X with reference to the main body 2. The pin 252 can for example be housed in a cylindrical bore made in the second ring 232. The tenon 252 has a recess 254 in which is positioned a rim 256 made on the first ring 230 in such a way that a rotation of the first ring 230 along the Y axis causes a translational movement of the tenon 252.

The unlocking pin 252 also has a groove 258 intended to permanently house a portion of the locking rocker 220.

Thus, the movement exhibited by the pin 252 during the rotation of the corolla 10 along the Y axis causes a deformation of the locking rocker 220 which deviates from its locking position, thus releasing the rake 214 which begins to pivot in the anti-clockwise direction of rotation, in the view of FIG. 5d, under the effect of the action of the spring 218 which can release the mechanical energy stored previously.

The locking rocker 220 can be repositioned by elasticity in the plane of the rake 214 or, alternatively, it is possible to provide a specific elastic return member which could be arranged to act either on the locking rocker 220, or directly on the tenon 252. Various alternative embodiments can be provided to ensure that the locking rocker 220 can indeed resume its locking position, by resuming a flat shape, once the rake 214 is positioned again in the position of arming. Thus, for example, it is possible to provide that the shaft of the rake 214 comprises a portion adjacent to the rake 214, defining a range, the radius of which corresponds to the radius of the rake 214 at the level of its notch 224 for locking. Alternatively, it is possible to provide that the tenon 252 is positioned so as to itself define an abutment for the locking rocker 220, so that its notch 226 cannot approach at a distance from the shaft of the rake. 214 less than the radius associated with the notch 224 of the rake. According to another alternative, it is possible to extend the locking rocker 220 by a feeler (in a manner similar to the first preferred embodiment variant) intended to cooperate with a stop such that its notch 226 cannot approach at a distance of the shaft of the rake 214 less than the radius associated with the notch 224 of the rake. Such a stop could in particular be provided on the control lever 210. A person skilled in the art will not encounter any particular difficulty in implementing a solution adapted to his own needs without departing from the scope of the present invention.

The rake 214 then drives the pinion 128 in rotation in the direction making it possible to simultaneously drive the wheel 132 and therefore to drive the animation device via the output mobile 140, until the rake 214 reaches its rest position, in abutment against the control lever 210, as illustrated in FIG. 5a.

[0098] The control ring 202 also resumes its rest position as illustrated in Figure 5a, as well as the control sensor 208 and the control lever 210, when the user releases the corolla 10 and that the corresponding elastic return member can fulfill its role.

[0099] Thus, the corolla 10 plays the role of an external control member capable of being actuated by a user, following a first predefined rotational movement, to load the spring 218 with mechanical energy. The corolla 10 can also be actuated later by the user, following a second predefined rotational movement, with a distinct axis of rotation, to act on the locking mechanism and release the spring 218 to enable it to supply its mechanical energy to the animation device 1000.

[0100] Thanks to the characteristics which have just been described, it is possible to produce an animated piece for the field of jewelery or jewelery capable of meeting a very high level of aesthetic requirement while presenting excellent ergonomics. .

The foregoing description sets out to describe a particular embodiment by way of non-limiting illustration and, the invention is not limited to the implementation of certain particular characteristics which have just been described, such as, for example, the nature and construction of the animation device or the shape illustrated and described for the various trim elements or for the spring. In particular, as has already been mentioned above, the animation module 1000 may have different constructions without departing from the scope of the invention. Those skilled in the art will in fact encounter no particular difficulty in implementing any known animation device suitable for implementing the present invention, in particular any device making it possible to exploit the rotational movement of the shaft of the mobile output in another rotation, in a translation, possibly circular, or even in several movements of several distinct components, etc...

[0102] Other variations are possible with respect to the preferred embodiment which has been described in detail, such as for example the production of a double and symmetrical cutout 206 in the control ring 202, in such a way that the corolla 10 can be turned along the axis of rotation X in one direction or the other to ensure the load of the spring 218.

[0103] Those skilled in the art will not encounter any particular difficulty in adapting the content of the present disclosure to their own needs and implementing a piece of jewelry or jewelry with animation comprising the same external control device to ensure the supply of mechanical energy necessary for the operation of the animation, by the implementation of a first rotational movement, and to trigger this animation on demand after an indefinite period following the last load in mechanical energy, by the implementation of a second rotational movement different from the first.
