Etat de la techniqueState of the art

Différents objets ornementaux comportant un dispositif d'animation sont connus depuis longtemps.Various ornamental objects comprising an animation device have been known for a long time.

A titre illustratif, le brevet US 3,247,683 décrit un tel objet comportant un boitier logeant une source d'énergie mécanique agencée pour commander la rotation d'une came agissant sur une figurine en forme de cheval pour simuler un mouvement de galop. Une tige-couronne est disposée sous le boitier pour permettre à un utilisateur de charger la source d'énergie mécanique, tandis qu'une tige de verrouillage mobile est agencée sur le côté du boitier pour permettre à l'utilisateur d'activer l'animation à la demande.By way of illustration, the patent US 3,247,683 describes such an object comprising a box housing a source of mechanical energy arranged to control the rotation of a cam acting on a figurine in the form of a horse to simulate a galloping movement. A stem-crown is arranged under the case to allow a user to charge the source of mechanical energy, while a movable locking pin is arranged on the side of the case to allow the user to activate the animation. on demand.

Certaines réalisations antérieures concernent des pièces de bijouterie ou de joaillerie pour lesquelles l'encombrement global de l'objet est un paramètre critique à prendre en compte.Certain previous embodiments relate to pieces of jewelry or jewelry for which the overall size of the object is a critical parameter to be taken into account.

Le brevet US 1,025,447 présente une pièce de bijouterie ou de joaillerie comportant un boitier logeant un dispositif d'animation entraîné à partir de l'énergie mécanique stockée dans un ressort de barillet. Le barillet comprend un arbre s'étendant hors du boitier et portant un organe de préhension pour permettre la charge du ressort de barillet par rotation de l'arbre. L'énergie mécanique est transmise du ressort de barillet à un organe animé, dont une portion est située en dehors du boitier, par l'intermédiaire d'un train d'engrenages et d'un échappement à ancre permettant de réguler la vitesse de dévidage du ressort de barillet. L'échappement à ancre remplit également le rôle d'un mécanisme de verrouillage, dans une certaine mesure, un choc suffisant à démarrer les mouvements de l'ancre pour activer l'animation. Une telle solution permet de limiter le nombre d'organes de préhension s'étendant hors du boitier, ce qui est plus favorable d'un point de vue de l'apparence décorative de l'objet, d'autant plus que ce dernier est destiné à être dissimulé dans un vêtement ou accessoire pour ne laisser apparaître que l'organe animé. Toutefois, le mode d'actionnement prévu n'est pas forcément satisfaisant du fait d'un certain manque de prévisibilité et du fait qu'il peut sembler étrange, voire peu rassurant, pour un utilisateur de devoir appliquer un choc à une pièce de bijouterie ou de joaillerie, probablement coûteuse, pour faire fonctionner son animation. En outre, le mécanisme de régulation et de verrouillage tel que décrit présente un encombrement non négligeable, ce qui n'est pas souhaitable dans la réalisation d'une pièce de bijouterie ou de joaillerie portable.The patent US 1,025,447 presents a piece of jewelry or jewelry comprising a case housing an animation device driven from mechanical energy stored in a barrel spring. The barrel comprises a shaft extending out of the housing and carrying a gripping member to allow the loading of the barrel spring 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, by means of a gear train and an anchor escapement making it possible to regulate the unwinding speed. of the barrel spring. The anchor escapement also fulfills the role of a locking mechanism, to a certain extent, enough 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 so as to reveal only the animated organ. However, the intended mode of actuation is not necessarily satisfactory due to a certain lack of predictability and the fact that it may seem strange, or even not very reassuring, for a user to have to apply a shock to a piece of jewelry. or jewelry, probably expensive, to make its animation work. In addition, the regulating 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.

Le brevet CH 332246 décrit une construction compacte adaptée pour la réalisation d'une broche ou d'une bague comportant un dispositif d'animation. Un composant décoratif de l'objet remplit discrètement la fonction d'un organe de commande externe permettant de recharger une source d'énergie mécanique, préalablement à l'activation de l'animation, par entraînement d'un pignon agencé pour rouler sur une denture fixe. Cette construction ne comporte aucun mécanisme de verrouillage du dispositif d'animation qui est par conséquent actionné aussitôt que la source d'énergie mécanique est suffisamment chargée.The patent CH 332246 describes a compact construction suitable for producing a spindle or a ring comprising an animation device. A decorative component of the object discreetly fulfills the function of an external control member making it possible to recharge a source of mechanical energy, prior to the activation of the animation, by driving a pinion arranged to run on a set of teeth. fixed. This construction does not include any mechanism for locking the animation device which is therefore actuated as soon as the source of mechanical energy is sufficiently charged.

Dans un domaine technique voisin, la demande de brevet WO 2015/124509 A1 décrit une pièce d'horlogerie comportant un mécanisme de sonnerie comprenant deux organes de commande qui peuvent éventuellement être imbriqués l'un dans l'autre et destinés à agir sur un même dispositif, à savoir un barillet de sonnerie. Une tige de remontoir est destinée à recharger le ressort de ce barillet lorsqu'elle est actionnée en rotation par un utilisateur, tandis qu'un tube-poussoir, agencé de manière coaxiale en référence à la tige de remontoir, est destiné à permettre au ressort de barillet de libérer son énergie vers le mécanisme de sonnerie en réponse à une pression exercée sur lui par l'utilisateur.In a related technical field, the patent application WO 2015/124509 A1 describes a timepiece comprising a striking mechanism comprising two control members which may optionally be nested one within the other and intended to act on the same device, namely a striking barrel. A winding stem is intended to recharge the spring of this barrel when it is actuated in rotation by a user, while a push tube, arranged coaxially with reference to the winding stem, is intended to allow the spring barrel to release its energy to the striking mechanism in response to pressure exerted on it by the user.

Grâce à ces caractéristiques, il est possible de réaliser une pièce de bijouterie ou de joaillerie à animation répondant à des critères élevés en matière d'esthétique tout en mettant en œuvre un dispositif d'animation simple et pratique à actionner. En effet, le fait d'utiliser un seul et même organe de commande externe pour effectuer deux opérations différentes permet de maintenir le mystère et un haut niveau de discrétion quant à la fonction technique de la pièce de bijouterie ou de joaillerie selon la présente invention, sans pour autant en sacrifier l'ergonomie. De plus, le fait d'avoir concentré deux fonctions sur un même organe de commande permet de maintenir une bonne compacité de la construction, ce qui la rend notamment adaptée à une mise en œuvre préférée sous la forme d'une bague.Thanks to these characteristics, it is possible to produce a piece of jewelry or jewelry with animation meeting high criteria in terms of aesthetics while implementing an animation device. simple and practical to operate. Indeed, the fact of using one and the same external control member to perform two different operations makes it possible to maintain the 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 a preferred implementation in the form of a ring.

Selon un mode de réalisation préféré, l'élément d'habillage est agencé de manière à pouvoir pivoter et se déplacer en translation en référence au bâti, la première action prédéfinie étant une rotation, la deuxième action prédéfinie étant une translation.According to a preferred embodiment, the covering element is arranged so as to be able to pivot and move in translation with reference to the frame, the first predefined action being a rotation, the second predefined action being a translation.

En outre, l'élément d'habillage peut avantageusement être agencé de telle manière que ses mouvements de rotation et de translation aient sensiblement pour référence un même axe X.In addition, the covering element can advantageously be arranged in such a way that its rotational and translational movements have substantially the same X axis as reference.

Grâce à ces caractéristiques, l'élément d'habillage est actionnable de manière simple et intuitive pour un utilisateur.Thanks to these characteristics, the covering element can be operated in a simple and intuitive manner for a user.

Suivant une variante de réalisation, on peut prévoir

  • que l'élément d'habillage soit mobile en translation entre une position de repos et une position tirée pour faire passer le mécanisme de verrouillage de son premier état vers son deuxième état, et
  • que la pièce de bijouterie ou de joaillerie comporte un organe de rappel élastique agencé pour agir sur l'élément d'habillage et tendre à le ramener vers sa position de repos.

  • that the piece of jewelry or jewelry comprises an elastic return member arranged to act on the covering element and tend to bring it back to its rest position.

Dans ce cas, il est avantageux de prévoir que l'élément d'habillage soit agencé pour fournir de l'énergie mécanique à la source d'énergie mécanique en réponse à une rotation dans un premier sens de rotation, tandis que l'organe de rappel élastique est également agencé pour pouvoir assurer un verrouillage en rotation de l'élément d'habillage dans le deuxième sens de rotation, opposé.In this case, it is advantageous to provide that the covering element is arranged to supply mechanical energy to the source of mechanical energy in response to a rotation in a first direction of rotation, while the control member elastic return is also arranged to be able to ensure a rotational locking of the covering element in the second direction of rotation, opposite.

Plus précisément, on peut en outre prévoir

  • que la source d'énergie mécanique comporte un ressort présentant une extrémité libre susceptible d'être déplacée en référence au bâti pour permettre une variation de l'énergie mécanique stockée par le ressort, l'extrémité libre étant susceptible de présenter une liaison cinématique avec le dispositif d'animation, et
  • que l'élément d'habillage soit solidaire d'un organe de charge et de verrouillage du ressort présentant sensiblement la forme d'un anneau et portant n ergots, n étant un entier égal ou supérieur à 1, agencés pour pouvoir entraîner à tour de rôle l'extrémité libre du ressort en rotation suivant le premier sens de rotation de l'élément d'habillage et pour pouvoir la verrouiller après une rotation d'un angle de 360°/n, l'organe de charge et de verrouillage étant par ailleurs agencé de manière à pouvoir libérer l'extrémité libre du ressort lorsque l'élément d'habillage est déplacé en translation depuis sa position de repos vers sa position tirée.
More precisely, it is also possible to provide

Selon des caractéristiques préférées supplémentaires de la présente invention, on peut également prévoir que l'organe de rappel élastique comporte alors au moins une butée escamotable agencée pour pouvoir se positionner en regard de surfaces d'arrêt ménagées sur l'organe de charge et de verrouillage, lorsque ce dernier verrouille l'extrémité libre du ressort, pour assurer le verrouillage en rotation de l'élément d'habillage dans le deuxième sens de rotation.According to additional preferred features of the present invention, provision can also be made for the resilient return member then to include at least one retractable stopper arranged to be able to be positioned opposite stop surfaces provided on the load and locking member. , when the latter locks the free end of the spring, to ensure the rotation locking of the covering element in the second direction of rotation.

Par ailleurs, on peut également prévoir que la pièce selon l'invention comporte un couvercle solidaire du bâti, pour assurer le positionnement et le maintien du ressort sur le bâti, le couvercle présentant une fente périphérique s'étendant sensiblement sur un angle de 360°/n et définissant une plage de déplacement dans laquelle est agencée l'extrémité libre du ressort.Furthermore, provision can also be made for the part according to the invention to include a cover integral with the frame, to ensure the positioning and retention of the spring on the frame, the cover having a peripheral slot extending substantially over an angle of 360 °. / n and defining a displacement range in which the free end of the spring is arranged.

Le couvercle peut alors avantageusement définir un support pour une platine du dispositif d'animation.The cover can then advantageously define a support for a plate of the animation device.

De plus, il est envisageable de prévoir que le ressort soit associé à un organe de sortie denté et rotatif, présentant la forme d'une couronne portant n rampes successives dont le point le plus haut de l'une est relié au point le plus bas de la suivante par une jonction abrupte définissant une surface d'actionnement pour l'extrémité libre du ressort, contre laquelle cette dernière est positionnée lorsque l'organe de charge et de verrouillage assure son verrouillage, de telle manière que l'extrémité libre du ressort puisse entraîner l'organe de sortie en rotation suivant le deuxième sens de rotation lorsque l'élément d'habillage est déplacé en translation depuis sa position de repos vers sa position tirée.In addition, it is conceivable to provide that the spring is associated with a toothed and rotating output member, having the shape of a ring carrying n successive ramps, the highest point of one of which is connected to the lowest point. of the next by a steep junction defining an actuating surface for the free end of the spring, against which this last is positioned when the load and locking member ensures its locking, so that the free end of the spring can drive the output member in rotation in the second direction of rotation when the covering element is moved in translation from its rest position to its pulled position.

De manière générale, on peut prévoir, lorsque la source d'énergie mécanique est associée à un organe de sortie denté et rotatif,

Mode(s) de réalisation de l'inventionMode (s) for carrying out the invention

La figure 1 représente une vue en perspective éclatée d'une pièce de bijouterie ou de joaillerie selon un mode de réalisation préféré de l'invention, c'est-à-dire se présentant sous la forme d'une bague 1. En effet, comme cela va ressortir de la suite de la description, les propriétés avantageuses de la construction selon la présente invention la rendent particulièrement adaptée pour une mise en œuvre sous la forme d'une bague mais, bien entendu, d'autres pièces de bijouterie ou de joaillerie portables, notamment plus encombrantes, pourront être réalisées sans pour autant sortir du cadre de l'invention.The figure 1 shows an exploded perspective view of a piece of jewelry or jewelry according to a preferred embodiment of the invention, that is to say in the form of a ring 1. Indeed, as This 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 pieces of jewelry or jewelry portable, in particular more bulky, can be produced without departing from the scope of the invention.

Dans un premier temps, la construction de la bague 1 va être présentée en relation avec la figure 1, ainsi que sur la base de la figure 2 qui représente une vue en coupe transversale partielle de la bague 1.First, the construction of the ring 1 will be presented in relation to the figure 1 , as well as on the basis of figure 2 which shows a partial cross-sectional view of the ring 1.

La bague 1 comporte un corps principal 2 présentant une ouverture annulaire 4 par laquelle la bague 1 est destinée à être portée sur un doigt d'un utilisateur, de manière conventionnelle.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.

Le corps principal 2 comporte un logement 6 présentant une forme de révolution d'axe X, perpendiculaire ici à l'axe de l'ouverture annulaire 4, de manière non limitative. Le logement 6 comporte un rebord annulaire 8 et définit un bâti pour les autres composants de la bague, qui vont maintenant être décrits et qui peuvent être répartis en deux groupes: des composants d'un module moteur 100 et des composants d'un module ou dispositif d'animation 200, tous ces composants étant enfermés sur le bâti par un élément d'habillage 10, présentant ici la forme d'une corolle de fleur et jouant le rôle de couvercle en coopération avec le logement 6.The main body 2 comprises a housing 6 having a shape of revolution of axis X, here perpendicular to the axis of the annular opening 4, in a nonlimiting 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 and components of a module or animation device 200, all these components being enclosed on the frame by a covering element 10, here having the shape of a flower corolla and playing the role of cover in cooperation with the housing 6.

Le module moteur 100 comporte une source d'énergie mécanique destinée à alimenter le dispositif d'animation 200, comprenant un ressort 102 agencé à l'intérieur d'un couvercle 104.The motor module 100 comprises a source of mechanical energy intended to supply the animation device 200, comprising a spring 102 arranged inside a cover 104.

Le couvercle 104 est solidaire du bâti en étant engagé à force, préférablement clipsé, à l'intérieur du logement 6. Une première extrémité 106 du ressort 102 est agencée en appui contre une surface d'appui (non visible) ménagée à l'intérieur du couvercle 104, de telle manière qu'elle présente une position fixe en référence au bâti de la bague 1. La deuxième extrémité 108 du ressort 102 est libre et destinée à être déplacée pour faire varier la quantité d'énergie mécanique stockée par le ressort 102. A cet effet, la deuxième extrémité 108 est disposée au travers d'une fente périphérique 110 ménagée dans la paroi latérale du couvercle 104.The cover 104 is integral with the frame by being forcibly engaged, preferably clipped, inside the housing 6. A first end 106 of the spring 102 is arranged to bear against a bearing surface (not visible) provided inside. of the cover 104, such that it has a fixed position with reference to the frame of the ring 1. The second end 108 of the spring 102 is free and intended to be moved to vary the amount of mechanical energy stored by the spring 102. For this purpose, the second end 108 is disposed through a peripheral slot 110 formed in the side wall of the cover 104.

Un organe de charge et de verrouillage 112, de forme générale annulaire, repose sur le couvercle 104 en étant libre de tourner en référence au bâti de la bague 1. L'organe de charge et de verrouillage 112 présente trois ergots 114 situés à 120° les uns des autres et orientés en direction du corps principal 2 de la bague 1, de telle manière qu'ils soient situés en regard de la paroi latérale du couvercle 104 et donc de la fente périphérique 110.A load and locking member 112, of generally annular shape, rests on the cover 104 while being free to rotate with reference to the frame of the ring 1. The load and locking member 112 has three lugs 114 located at 120 °. from each other and oriented in the direction of the main body 2 of the ring 1, such that they are located opposite the side wall of the cover 104 and therefore the peripheral slot 110.

Ainsi, l'organe de charge et de verrouillage 112 est susceptible de coopérer avec l'extrémité libre 108 du ressort 102, par l'intermédiaire de ses ergots 114, d'une manière qui sera exposée plus loin.Thus, the load and locking member 112 is able to cooperate with the free end 108 of the spring 102, by means of its lugs 114, in a manner which will be explained below.

L'organe de charge et de verrouillage 112 est surmonté d'un organe de rappel élastique 116 comprenant une plaque centrale plane 118 présentant trois évidements périphériques 120 situés à 120° les uns des autres et dans lesquels sont ménagés trois bras 122, inclinés de manière à s'étendre hors du plan de la plaque centrale 118, en direction de l'organe de charge et de verrouillage 112. Chaque bras 122 est plus court que l'évidement 120 dans lequel il est situé pour ménager trois espaces vides dont la fonction ressortira de la suite de la description. L'organe de rappel élastique 116 est rendu solidaire du couvercle 104, ici par vissage, et présente par conséquent une orientation fixe en référence au bâti de la bague 1.The load and locking member 112 is surmounted by an elastic return member 116 comprising a flat central plate 118 having three peripheral recesses 120 located at 120 ° to each other and in which are formed three arms 122, inclined so to extend out of the plane of the central plate 118, in the direction of the load and locking member 112. Each arm 122 is shorter than the recess 120 in which it is located to provide three empty spaces whose function will emerge from the remainder of the description. The elastic return member 116 is made integral with the cover 104, here by screwing, and consequently has a fixed orientation with reference to the frame of the ring 1.

Il ressort de la figure 1 que l'organe de charge et de verrouillage 112 porte trois protubérances 124 situés à 120° les unes des autres et agencées en regard des bras 122. Chaque protubérance 124 présente un chanfrein 126 optionnel à une extrémité. On comprend ainsi que lorsque l'organe de charge et de verrouillage 112 se déplace en rotation dans le sens de rotation anti-horaire sur la vue de la figure 1, chaque protubérance 124 entre en contact avec l'un des bras 122 de l'organe de rappel élastique 116 par son chanfrein 126, ce qui a pour effet de déformer les bras 122 pour les repousser en direction du plan de la plaque centrale 118. En continuant de tourner, chaque bras 122 quitte sa protubérance 124 et reprend son état déformé par défaut, comme illustré sur la figure 1. Chaque protubérance 124 se trouve alors située en regard de l'un des espaces vides mentionnés plus haut. On comprend que, dans cette configuration, l'extrémité arrière 128 de chaque protubérance 124 joue le rôle d'une surface d'arrêt coopérant avec l'extrémité libre du bras 122 correspondant pour empêcher une rotation de l'organe de charge et de verrouillage 112 en sens inverse. Ainsi, les extrémités libres des bras 122 jouent le rôle de butées escamotables pour assurer le verrouillage en rotation de l'organe de charge et de verrouillage 112, dans un sens de rotation prédéfini et dans une certaine configuration de la bague 1.It emerges from the figure 1 that the load and locking member 112 carries three protuberances 124 located at 120 ° from each other and arranged opposite the arms 122. Each protuberance 124 has an optional chamfer 126 at one end. It will thus be understood that when the load and locking member 112 rotates in the anti-clockwise direction of rotation in the view of the figure 1 , each protuberance 124 comes into contact with one of the arms 122 of the elastic return member 116 via its chamfer 126, which has the effect of deforming the arms 122 to push them back in the direction of the plane of the central plate 118. As you continue to rotate, each arm 122 leaves its protuberance 124 and returns to its default deformed state, as shown in figure figure 1 . Each protuberance 124 is then located opposite one of the empty spaces mentioned above. It will be understood that, in this configuration, the rear end 128 of each protuberance 124 acts as a stop surface cooperating with the free end of the corresponding arm 122 to prevent rotation of the load and locking member 112 in the opposite direction. Thus, the free ends of the arms 122 act as retractable stops to ensure the rotation locking of the load and locking member 112, in a predefined direction of rotation and in a certain configuration of the ring 1.

Par ailleurs, lorsqu'un ergot 114 de l'organe de charge et de verrouillage 112 entraîne l'extrémité libre 108 du ressort 102 dans le sens de rotation anti-horaire, le ressort 102 est chargé pour stocker de l'énergie mécanique. Or, le ressort 102 coopère également avec un organe de sortie, présentant ici la forme d'une couronne 130 à denture interne, pour transmettre l'énergie mécanique libérée au dispositif d'animation 200.Furthermore, when a lug 114 of the load and locking member 112 drives the free end 108 of the spring 102 in the anti-clockwise direction of rotation, the spring 102 is loaded to store mechanical energy. However, the spring 102 also cooperates with an output member, here having the shape of a ring 130 with internal teeth, to transmit the mechanical energy released to the animation device 200.

La couronne 130 porte trois rampes successives, ménagées en surépaisseur sur sa face située du côté du ressort 102, dont chacune s'étend sur un angle de 120° et dont le point le plus haut de l'une est relié au point le plus bas de la suivante par une jonction abrupte définissant une surface d'actionnement 132. Ces dernières sont destinées à coopérer à tour de rôle avec l'extrémité libre 108 du ressort 102 lorsque cette dernière se déplace dans le sens de rotation horaire sur la vue de la figure 1. Ainsi, lorsque le ressort 102 libère son énergie mécanique, son extrémité libre 108 est susceptible d'entraîner la couronne 130 en rotation dans le sens de rotation horaire sur la vue de la figure 1.The crown 130 carries three successive ramps, formed in extra thickness on its face located on the side of the spring 102, each of which extends over an angle of 120 ° and the highest point of one of which is connected to the lowest point. of the following by an abrupt junction defining an actuating surface 132. The latter are intended to cooperate in turn with the free end 108 of the spring 102 when the latter moves in the direction of clockwise rotation in the view of the figure 1 . Thus, when the spring 102 releases its mechanical energy, its free end 108 is capable of driving the ring 130 in rotation in the direction of clockwise rotation in the view of the figure 1 .

La couronne 130 constitue par conséquent le point de départ d'une chaine cinématique reliant le ressort 102 au dispositif d'animation 200. La couronne 130 joue, à cet effet, le rôle d'une première roue solaire d'un engrenage planétaire en étant agencée en prise permanente avec un premier pignon 134 d'un satellite dont le deuxième pignon 136, solidaire du premier en rotation, est agencé en prise permanente avec une deuxième roue solaire 138. Cette dernière est disposée au fond du logement 6 de la bague 1 en étant maintenue fixe par rapport au bâti de la bague 1, notamment par une goupille 140.The crown 130 therefore constitutes the starting point of a kinematic chain connecting the spring 102 to the animation device 200. The crown 130 plays, for this purpose, the role of a first sun wheel of a planetary gear by being arranged in permanent engagement with a first pinion 134 of a satellite whose second pinion 136, integral with the first in rotation, is arranged in permanent engagement with a second sun wheel 138. The latter is disposed at the bottom of the housing 6 of the ring 1 while being kept fixed relative to the frame of the ring 1, in particular by a pin 140.

De ce fait, toute rotation de la couronne 130 dans le sens de rotation horaire sur la vue de la figure 1 fait tourner le satellite dont le deuxième pignon 136 roule sur la deuxième roue solaire 138, entraînant une rotation du porte-satellite 142 dans le sens de rotation anti-horaire sur la vue de la figure 1.Therefore, any rotation of the crown 130 in the clockwise direction of rotation in the view of the figure 1 rotates the satellite whose second pinion 136 rolls on the second sun wheel 138, causing the planet carrier 142 to rotate in the anti-clockwise direction of rotation in the view of the figure 1 .

Le porte-satellite 142 comprend un arbre 144 s'étendant jusqu'au dispositif d'animation 200 pour transmettre à ce dernier l'énergie mécanique libérée par le ressort 102, avec une vitesse de rotation plus élevée que celle de la couronne 130 du fait de la mise en œuvre de l'engrenage planétaire.The planet carrier 142 comprises a shaft 144 extending to the animation device 200 for transmitting to the latter the mechanical energy released by the spring 102, with a speed of rotation higher than that of the ring 130 because of the implementation of the planetary gear.

On note qu'un frein inertiel 146 est porté par le porte-satellite 142 pour réguler sa vitesse de rotation et donc celle de l'arbre 144.Note that an inertial brake 146 is carried by the planet carrier 142 to regulate its speed of rotation and therefore that of the shaft 144.

En ce qui concerne le module ou dispositif d'animation 200, il n'est sommairement décrit ici qu'à titre illustratif non limitatif, étant entendu qu'il peut présenter un nombre très élevé de réalisations possibles différentes sans pour autant sortir du cadre de l'invention.With regard to the animation module or device 200, it is only briefly described here by way of non-limiting illustration, it being understood that it can present a very high number of different possible embodiments without departing from the scope of invention.

Le dispositif d'animation 200 comporte une platine 202 vissée sur le couvercle 104, avec interposition de l'organe de rappel élastique 116.The animation device 200 comprises a plate 202 screwed onto the cover 104, with the interposition of the elastic return member 116.

La platine 202 est surmontée d'une platine auxiliaire 204 pour permettre l'assemblage entre pierres des constituants d'un mécanisme d'entraînement de différents organes dont les déplacements définissent une animation.The plate 202 is surmounted by an auxiliary plate 204 to allow the assembly between stones of the constituents of a drive mechanism of different members whose movements define an animation.

Plus précisément ici, le dispositif d'animation 200 comporte une came 206, non circulaire et/ou excentrée, chassée sur l'arbre 144 pour jouer le rôle d'organe d'entrée et agencée pour coopérer avec un palpeur 208. Ce dernier est porté par une bascule 210 portant également un râteau 212 agencé en prise avec un premier mobile d'affichage 214, lui-même en prise avec un deuxième mobile d'affichage 216 adjacent, de telle manière que les deux mobiles d'affichage tournent de manière simultanée mais en sens inverses. La forme de la came 206 permet de donner une impression de mouvement aléatoire à l'ensemble.More precisely here, the animation device 200 comprises a cam 206, which is not circular and / or eccentric, driven onto the shaft 144 to act as an input member and arranged to cooperate with a probe 208. The latter is carried by a rocker 210 also carrying a rake 212 arranged in engagement with a first display mobile 214, itself in engagement with an adjacent second display mobile 216, such that the two display mobile units rotate in such a way simultaneous but in opposite directions. The shape of the cam 206 makes it possible to give an impression of random movement to the assembly.

Chacun des mobiles d'affichage 214 et 216 comprend un axe, qui traverse la platine auxiliaire 204 ainsi qu'un cadran 218, et porte une aile de papillon 220, qui pourra avantageusement être réalisée en une pierre précieuse. Le cadran 218 porte un élément additionnel 222 figurant le corps du papillon en référence auquel battent les ailes lorsque l'animation est actionnée.Each of the display mobiles 214 and 216 comprises an axis, which passes through the auxiliary plate 204 as well as a dial 218, and carries a butterfly wing 220, which may advantageously be made of a precious stone. The dial 218 carries an additional element 222 representing the body of the butterfly with reference to which the wings flap when the animation is activated.

L'élément d'habillage 10 est ensuite engagé autour des modules moteur 100 et d'animation 200 pour les enfermer et les protéger. Celui-ci comporte un cylindre central 12 muni de quatre trous 14 permettant de rendre l'élément d'habillage 10 solidaire de l'organe de charge et de verrouillage 112 au moyen de vis 16.The covering element 10 is then engaged around the motor 100 and animation 200 modules 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 loading and locking member 112 by means of screws 16.

Une glace de protection (non représentée) peut avantageusement être prévue pour fermer la face libre du cylindre 12 et protéger les composants du dispositif d'animation 200.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 200.

Le fonctionnement de la bague 1 va être décrit à présent sur la base des éléments ci-dessus ainsi que des figures 3a à 3d qui représentent des vues en perspective de la bague 1 à différents instants d'une séquence complète, comprenant une opération de charge du ressort 102 suivie de l'actionnement d'une animation, la bague 1 ayant été représentée sans l'élément d'habillage 10 et sans le module d'animation 200 pour plus de clarté.The operation of the ring 1 will now be described on the basis of the above elements as well as the figures 3a to 3d which represent perspective views of the ring 1 at different times of a complete sequence, comprising an operation of loading the spring 102 followed by the actuation of an animation, the ring 1 having been shown without the covering element 10 and without the animation module 200 for clarity.

La figure 3a représente la bague 1 alors que le ressort 102 est désarmé. Son extrémité libre 108 est alors agencée contre une première extrémité de la fente périphérique 110 du couvercle 104, en appui également contre un ergot 114 de l'organe de charge et de verrouillage 112.The figure 3a represents the ring 1 while the spring 102 is disarmed. Its free end 108 is then arranged against a first end of the peripheral slot 110 of the cover 104, also resting against a lug 114 of the loading and locking member 112.

Partant de cette configuration, un utilisateur ne peut pas faire tourner l'organe de charge et de verrouillage 112 dans le sens de rotation horaire, sur la vue de la figure 3a, du fait de la coopération entre les protubérances 124 et les bras 122.Starting from this configuration, a user cannot turn the load and locking member 112 in the clockwise direction of rotation, in the view of the figure 3a , due to the cooperation between the protuberances 124 and the arms 122.

Seule une rotation dans le sens de rotation anti-horaire est possible, par action sur l'élément d'habillage 10 jouant avantageusement et mystérieusement le rôle d'un organe de commande externe, ce qui est illustré sur la figure 3b. L'organe de charge et de verrouillage 112 tourne en référence au bâti de la bague 1, donc également en référence à l'organe de rappel élastique 116 et au couvercle 104. Lors de ce déplacement, l'ergot 114 entraîne l'extrémité libre 108 du ressort 102 en direction de l'autre extrémité de la fente périphérique 110. Dans le même temps, l'extrémité libre 108 du ressort 102 monte progressivement sur l'une des rampes de la couronne 130.Only a rotation in the anti-clockwise direction of rotation is possible, by acting on the covering element 10 advantageously and mysteriously playing the role of an external control member, which is illustrated in the figure. figure 3b . The load and locking member 112 rotates with reference to the frame of the ring 1, therefore also with reference to the elastic return member 116 and to the cover 104. During this movement, the lug 114 drives the free end. 108 of the spring 102 towards the other end of the peripheral slot 110. At the same time, the free end 108 of the spring 102 gradually rises on one of the ramps of the crown 130.

La figure 3c illustre la configuration en fin de course, lorsque l'extrémité libre 108 du ressort 102 est parvenue en butée contre l'autre extrémité de la fente périphérique 110 et est tombée sur la rampe suivante en étant située immédiatement à côté d'une surface d'actionnement 132 de la couronne 130. Dans cette configuration, l'organe de charge et de verrouillage 112 est lui-même immobilisé, d'une part, par la résistance que lui oppose l'extrémité libre 108 du ressort 102 et, d'autre part, par la coopération entre les protubérances 124 et les bras 122.The figure 3c illustrates the configuration at the end of the stroke, when the free end 108 of the spring 102 has come into abutment against the other end of the peripheral slot 110 and has fallen onto the next ramp being located immediately next to a surface of actuation 132 of the crown 130. In this configuration, the load and locking member 112 is itself immobilized, on the one hand, by the resistance opposed to it by the free end 108 of the spring 102 and, on the other hand hand, by the cooperation between the protuberances 124 and the arms 122.

Le ressort 102 est alors chargé avec un maximum d'énergie mécanique, qu'il peut stocker aussi longtemps que l'utilisateur n'entreprend aucune autre action sur l'élément d'habillage 10. La combinaison des effets de l'organe élastique de rappel 116 et de l'organe de charge et de verrouillage 112 donne lieu à la fonction d'un mécanisme de verrouillage du ressort 102.The spring 102 is then loaded 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. The combination of the effects of the elastic member of return 116 and the load and locking member 112 gives rise to the function of a locking mechanism for the spring 102.

Si l'organe de rappel élastique 116 est susceptible d'exercer une force sur l'organe de charge et de verrouillage 112 tendant à plaquer ce dernier contre le couvercle 104, cette force peut être surmontée par un utilisateur, en exerçant une force de traction sur l'élément d'habillage 10 (tendant donc à l'éloigner du corps principal 2 de la bague 1).If the elastic return member 116 is capable of exerting a force on the load and locking member 112 tending to press the latter against the cover 104, this force can be overcome by a user, by exerting a tensile force on the covering element 10 (therefore tending to move it away from the main body 2 of the ring 1).

Une telle action est illustrée sur la figure 3d. En réponse à une traction exercée sur la corolle, visant à la faire passer d'une première position axiale de repos à une position tirée, l'organe de charge et de verrouillage 112 est écarté du couvercle 104, en déformant les bras 122, de telle manière que l'extrémité libre 108 du ressort 102 puisse être libérée.Such an action is illustrated on the 3d figure . In response to a pull exerted on the corolla, aiming to make it pass from a first axial position of rest to a pulled position, the load and locking member 112 is moved away from the cover 104, by deforming the arms 122, of such that the free end 108 of the spring 102 can be released.

Le ressort 102 peut alors se détendre en libérant son énergie mécanique par déplacement de son extrémité libre 108 dans le sens de rotation horaire sur la vue de la figure 3d, provoquant une rotation de la couronne 130 dans le même sens comme décrit plus haut.The spring 102 can then relax by releasing its mechanical energy by moving its free end 108 in the direction of clockwise rotation as seen from the 3d figure , causing the crown 130 to rotate in the same direction as described above.

L'utilisateur peut relâcher presque immédiatement la corolle, après avoir actionné l'animation, pour permettre à l'organe de charge et de verrouillage 112 de se repositionner en appui contre le couvercle 104 aussitôt que l'extrémité libre 108 du ressort 102 a franchi l'ergot 114 qui la verrouillait jusque-là.The user can almost immediately release the corolla, after having actuated the animation, to allow the load and locking member 112 to reposition itself in abutment against the cover 104 as soon as the free end 108 of the spring 102 has passed. the lug 114 which locked it until then.

Ainsi, la corolle joue le rôle d'un organe de commande externe susceptible d'être actionné par un utilisateur, suivant une première action prédéfinie, pour charger le ressort 102 en énergie mécanique. L'ensemble comportant l'organe de charge et de verrouillage 112 et l'organe élastique de rappel 116 remplit quant à lui le rôle d'un mécanisme de verrouillage présentant un premier état dans lequel il verrouille le ressort 102, pour lui permettre de stocker l'énergie mécanique emmagasinée pour une durée indéfinie, comme illustré sur la figure 3c et décrit plus haut. La corolle peut alors être actionnée par l'utilisateur, suivant une deuxième action prédéfinie illustrée ici à titre non limitatif sous la forme d'une traction, pour agir sur le mécanisme de verrouillage et le faire passer dans un deuxième état dans lequel il libère le ressort 102 pour lui permettre de fournir son énergie mécanique au dispositif d'animation 200. Dans le deuxième état du mécanisme de verrouillage, l'organe de charge et de verrouillage 112 est rapproché de l'organe élastique de rappel 116, ses protubérances 124 étant engagées dans les évidements 120 tandis que les bras 122 sont déformés. Dans cette position, l'ergot 114 qui assurait le verrouillage de l'extrémité libre 108 du ressort 102 la libère comme décrit plus haut en relation avec l'illustration de la figure 3d.Thus, the corolla plays the role of an external control member capable of being actuated by a user, according to a first predefined action, to charge the spring 102 with mechanical energy. The assembly comprising the load and locking member 112 and the elastic return member 116 fulfills the role of a locking mechanism having a first state in which it locks the spring 102, to allow it to store the mechanical energy stored for an indefinite period, as illustrated in the figure 3c and described above. The corolla can then be actuated by the user, following a second predefined action illustrated here without limitation in the form of a pull, to act on the locking mechanism and make it go into a second state in which it releases the spring 102 to allow it to supply its mechanical energy to the animation device 200. In the second state of the locking mechanism, the load and locking member 112 is brought closer to the elastic return member 116, its protuberances 124 being engaged in the recesses 120 while the arms 122 are deformed. In this position, the lug 114 which ensures the locking of the free end 108 of the spring 102 releases it as described above in relation to the illustration of the 3d figure .

Grâce aux caractéristiques qui viennent d'être décrites, il est possible de réaliser une pièce de bijouterie ou de joaillerie à animation susceptible de répondre à un niveau d'exigence esthétique très élevé tout en présentant une excellente ergonomie.Thanks to the characteristics which have just been described, it is possible to produce an animated piece of jewelry or jewelry capable of meeting a very high level of aesthetic requirement while exhibiting excellent ergonomics.

La description qui précède s'attache à décrire un mode de réalisation particulier à titre d'illustration non limitative et, l'invention n'est pas limitée à la mise en œuvre de certaines caractéristiques particulières qui viennent d'être décrites, comme par exemple la nature et la construction du dispositif d'animation ou encore la forme illustrée et décrite pour les différents éléments d'habillage ou pour le ressort. En particulier, comme cela a déjà été mentionné plus haut, le module d'animation 200 pourra présenter différentes constructions sans pour autant sortir du cadre de l'invention. L'homme du métier ne rencontrera en effet aucune difficulté particulière pour mettre en œuvre tout dispositif d'animation connu adapté à la mise en œuvre de la présente invention, notamment tout dispositif permettant d'exploiter le mouvement de rotation de l'arbre d'entrée en une autre rotation, en une translation, éventuellement circulaire, voire en plusieurs mouvements de plusieurs composants distincts, etc...The foregoing description attempts to describe a particular embodiment by way of nonlimiting 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 form illustrated and described for the various trim elements or for the spring. In particular, as has already been mentioned above, the animation module 200 can 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 implementation of the present invention, in particular any device making it possible to use the rotational movement of the input shaft in another rotation, in a translation, possibly circular, or even in several movements of several distinct components, etc ...

Si la mise en œuvre d'un engrenage planétaire est préférée, elle n'est pas absolument nécessaire pour profiter des avantages de la présente invention. De manière générale, on notera que l'invention n'est pas non plus limitée au nombre d'actionnements n, tel que décrit et illustré, qui sont nécessaires pour faire un tour complet avec la corolle. En effet, une réalisation préférée selon laquelle n vaut 3 a été illustrée ici à titre non limitatif, mais l'homme du métier ne rencontrera pas de difficulté particulière pour adapter le présent enseignement en fonction de ses propres besoins sans pour autant sortir du cadre de la présente invention. On remarque bien entendu que le nombre n, entier égal ou supérieur à 1, est déterminant pour définir la plage angulaire d'actionnement de la corolle pour charger le ressort, en fonction du nombre d'ergots de l'organe de charge et de verrouillage, du nombre de ses protubérances et du nombre de rampes ménagées en surépaisseur sur la couronne de sortie. Par ailleurs, la fonction de rappel de l'organe de rappel élastique pourrait être mise en œuvre indépendamment de sa fonction de verrouillage en rotation de l'organe de charge et de verrouillage. Ainsi, une seule butée pourrait suffire pour assurer ce verrouillage en coopérant à tour de rôle avec différentes protubérances de l'organe de charge et de verrouillage. De manière similaire, on notera que la corolle pourrait être actionnée dans le sens de rotation inverse à celui décrit pour charger le ressort sans pour autant sortir du cadre de l'invention. En outre, la deuxième action prédéfinie à effectuer pour libérer le ressort a été décrite comme une traction exercée sur la corolle, mais l'homme du métier pourra mettre en œuvre une autre action similaire sans sortir du cadre de l'invention, notamment une pression. Dans ce cas, l'organe élastique de rappel 116 serait avantageusement intercalé entre l'organe de charge et de verrouillage 112 et le couvercle 104.While the implementation of a planetary gear is preferred, it is not absolutely necessary to take advantage of the advantages of the present invention. In general, it will be noted that the invention is not limited either to the number of actuations n, as described and illustrated, which are necessary to make a complete revolution with the corolla. Indeed, a preferred embodiment according to which n is 3 has been illustrated here in a non-limiting way, but the person skilled in the art will not encounter any particular difficulty in adapting the present teaching according to his own needs without departing from the scope of the present invention. It will of course be noted that the number n, an integer equal to or greater than 1, is decisive in defining the angular range of actuation of the corolla to load the spring, as a function of the number of lugs of the loading and locking member. , the number of its protuberances and the number of ramps provided with extra thickness on the output ring. Furthermore, the return function of the elastic return member could be implemented independently of its function of locking the load member in rotation and locking it. Thus, a single stop could suffice to ensure this locking by cooperating in turn with different protuberances of the load and locking member. Similarly, it will be noted that the corolla could be actuated in the direction of rotation opposite to that described in order to load the spring without however departing from the scope of the invention. In addition, the second predefined action to be performed to release the spring has been described as a traction exerted on the corolla, but a person skilled in the art will be able to implement another similar action without departing from the scope of the invention, in particular pressure. . In this case, the elastic return member 116 would advantageously be interposed between the load and locking member 112 and the cover 104.

L'homme du métier ne rencontrera pas de difficulté particulière pour adapter le contenu de la présente divulgation à ses propres besoins et mettre en œuvre une pièce de bijouterie ou de joaillerie à animation comportant un même organe de commande externe pour assurer l'apport en énergie mécanique nécessaire au fonctionnement de l'animation et pour enclencher cette animation à la demande après une durée indéfinie suivant la dernière charge en énergie mécanique.Those skilled in the art will not encounter any particular difficulty in adapting the content of the present disclosure to their own needs and in implementing implements a piece of jewelry or animated jewelry comprising the same external control member to ensure the supply of mechanical energy necessary for the operation of the animation and to trigger this animation on demand after an indefinite period following the last energy charge mechanical.
