Description

La présente invention a pour objet un mécanisme d'animation permettant d'animer un objet (personnage, figurine, animal, fleur...). Le mécanisme d'animation selon l'invention est notamment destiné à équiper une pièce d'horlogerie.The subject of the present invention is an animation mechanism making it possible to animate an object (character, figurine, animal, flower, etc.). The animation mechanism according to the invention is intended in particular to equip a timepiece.

De nombreux mécanismes d'animation sont connus et permettent de mettre en mouvement un personnage, une figurine, un animal ou encore une fleur pour obtenir un effet divertissant. Ce mouvement est en général un mouvement cyclique : partant d'une position initiale, l'objet se déplace dans une séquence déterminée de positions avant de revenir à sa position initiale. Ces mécanismes sont particulièrement utilisés en joaillerie ou en horlogerie. En général, lorsqu'ils sont intégrés à un mouvement d'une pièce d'horlogerie, ils sont agencés pour déclencher l'animation à des moments déterminés (passage de l'heure par exemple) ou à la demande via un organe de commande actionnable par l'utilisateur.Many animation mechanisms are known and make it possible to set a character, a figurine, an animal or even a flower in motion to obtain an entertaining effect. This movement is generally a cyclical movement: starting from an initial position, the object moves through a determined sequence of positions before returning to its initial position. These mechanisms are particularly used in jewelry or watchmaking. In general, when they are integrated into a movement of a timepiece, they are arranged to trigger the animation at determined times (passing of the hour for example) or on demand via an operable control device by the user.

Un mécanisme d'animation comprend souvent un organe moteur qui transmet au mécanisme d'animation l'énergie nécessaire à la mise en mouvement de l'objet. Dans le cas où le mécanisme d'animation est associé à un mouvement de pièce d'horlogerie, l'organe moteur du mécanisme d'animation peut être soit l'organe moteur du mouvement ou un organe moteur distinct dédié uniquement au mécanisme d'animation.An animation mechanism often includes a motor member which transmits to the animation mechanism the energy necessary to set the object in motion. In the case where the animation mechanism is associated with a timepiece movement, the motor member of the animation mechanism can be either the motor member of the movement or a separate motor member dedicated solely to the animation mechanism .

Le document D1 décrit un dispositif de mesure de couple pour un mécanisme de sonnerie permettant de surveiller la réserve de marche et de bloquer le déclenchement de la sonnerie si cette réserve de marche n'est pas suffisante pour un fonctionnement correct. Le dispositif de mesure de couple détermine deux états de la réserve de marche et dans un de ces états, la sonnerie n'est donc pas déclenchée et ses éléments (levée, marteaux..) restent immobiles.Document D1 describes a torque measurement device for a striking mechanism making it possible to monitor the power reserve and to block the triggering of the striking if this power reserve is not sufficient for correct operation. The torque measuring device determines two states of the power reserve and in one of these states, the chime is therefore not triggered and its elements (lift, hammers, etc.) remain stationary.

Le but de la présente invention est de réaliser un nouveau mécanisme d'animation permettant d'animer un objet (personnage, figurine, animal...), notamment pour une pièce d'horlogerie, et dans lequel les mouvements de l'objet à animer et notamment le rythme de ces mouvements dépendent de la réserve de marche de l'organe moteur transmettant l'énergie au mécanisme d'animation.The object of the present invention is to produce a new animation mechanism making it possible to animate an object (character, figurine, animal, etc.), in particular for a timepiece, and in which the movements of the object to animating and in particular the rhythm of these movements depend on the power reserve of the motor component transmitting the energy to the animation mechanism.

As a variant, the animation mechanism according to the invention could also equip a jewel or any other appropriate object.

Dans la forme d'exécution illustrée, le mécanisme d'animation équipe une pièce d'horlogerie comprenant un mouvement mécanique. L'organe moteur du mécanisme d'animation est un barillet d'animation (non illustré). De préférence, le barillet d'animation est distinct du barillet principal du mouvement de la pièce d'horlogerie et est destiné exclusivement au mécanisme d'animation. En variante, l'organe moteur pourrait être le barillet du mouvement de la pièce d'horlogerie ou tout autre organe moteur approprié qu'il soit dédié exclusivement ou non au mécanisme d'animation. Le remontage du barillet d'animation peut être soit manuel soit automatique via un mécanisme de remontage automatique et une masse oscillante par exemple.In the illustrated embodiment, the animation mechanism equips a timepiece comprising a mechanical movement. The driving member of the animation mechanism is an animation barrel (not shown). Preferably, the animation barrel is separate from the main barrel of the movement of the timepiece and is intended exclusively for the animation mechanism. As a variant, the driving member could be the barrel of the movement of the timepiece or any other suitable driving member whether or not it is exclusively dedicated to the animation mechanism. Winding of the animation barrel can be either manual or automatic via an automatic winding mechanism and an oscillating weight, for example.

Le mécanisme d'animation comprend un mobile de commande destiné à commander un dispositif de déclenchement de l'animation. Dans la forme d'exécution illustrée, le mobile de commande est une came de commande 1 ayant la forme d'une étoile à dix-neuf dents et le dispositif de déclenchement comprend un levier ou bascule de déclenchement 2, un doigt de déclenchement 3, un levier 4 et un râteau 9. La came de commande 1 est reliée cinématiquement au barillet d'animation pour son entraînement.The animation mechanism includes a control mobile intended to control an animation triggering device. In the illustrated embodiment, the control wheel set is a control cam 1 having the shape of a star with nineteen teeth and the trigger device comprises a trigger lever or rocker 2, a trigger finger 3, a lever 4 and a rake 9. The control cam 1 is kinematically connected to the animation barrel for its drive.

La bascule de déclenchement 2 est agencée pour pivoter en un point fixe P et est soumise à l'action d'un sautoir (non illustré) qui tend à la maintenir en contact avec la came de commande 1. Le doigt de déclenchement 3 est pivoté sur la bascule de déclenchement 2.The trigger rocker 2 is arranged to pivot at a fixed point P and is subjected to the action of a jumper (not shown) which tends to keep it in contact with the control cam 1. The trigger finger 3 is pivoted on trigger rocker 2.

Le doigt de déclenchement 3 comprend une extrémité active 3.1 destinée à coopérer avec une palette de déclenchement 9.1 située à l'extrémité d'un premier bras du râteau 9. Le râteau 9 comprend un second bras portant une denture 9.2 et est pivoté en un second point fixe A. Le râteau 9 est relié cinématiquement via sa denture 9.2 avec l'objet à animer du mécanisme d'animation selon l'invention pour son animation. En particulier, selon la forme d'exécution illustrée, le mécanisme d'animation est agencé pour que l'amplitude de la rotation du râteau 9 détermine le rythme ou la fréquence de l'animation.The trigger finger 3 includes an active end 3.1 intended to cooperate with a trigger blade 9.1 located at the end of a first arm of the rake 9. The rake 9 includes a second arm carrying a set of teeth 9.2 and is pivoted in a second fixed point A. The rake 9 is kinematically connected via its toothing 9.2 with the object to be animated by the animation mechanism according to the invention for its animation. In particular, according to the illustrated embodiment, the animation mechanism is arranged so that the amplitude of the rotation of the rake 9 determines the rhythm or the frequency of the animation.

Le levier 4 est pivoté au même point fixe P que la bascule de déclenchement 2 et destiné à coopérer avec une came de réserve de marche 5. La position de la came de réserve de marche 5 est indexée à la réserve de marche du barillet d'animation. Dans la présente forme d'exécution, la came de réserve de marche 5 est reliée cinématiquement à la sortie du différentiel de réserve de marche d'un mécanisme indicateur de réserve de marche du barillet d'animation. Ce type de mécanisme est bien connu et ne sera pas décrit plus en détail ici.Lever 4 is pivoted at the same fixed point P as trigger rocker 2 and intended to cooperate with a power reserve cam 5. The position of the power reserve cam 5 is indexed to the power reserve of the barrel of animation. In the present embodiment, the power reserve cam 5 is kinematically connected to the output of the power reserve differential of a power reserve indicator mechanism of the animation barrel. This type of mechanism is well known and will not be described in more detail here.

La came de réserve de marche 5 est agencée pour définir au moins deux états de la réserve de marche du barillet d'animation (par exemple supérieure ou égale à quarante heures et inférieure à quarante heures). Dans la forme d'exécution illustrée, la came de réserve de marche 5 comprend cinq faces a, b, c, d, e de rayon différent et définissant donc cinq états de la réserve de marche du barillet d'animation. Pour chacun de ces états, le rythme ou la fréquence de l'animation est alors diffèrent du rythme ou de la fréquence de l'animation dans les autres états.The power reserve cam 5 is arranged to define at least two states of the power reserve of the animation barrel (for example greater than or equal to forty hours and less than forty hours). In the illustrated embodiment, the power reserve cam 5 comprises five faces a, b, c, d, e of different radius and therefore defining five states of the power reserve of the animation barrel. For each of these states, the rhythm or the frequency of the animation is then different from the rhythm or the frequency of the animation in the other states.

Le levier 4 porte une goupille de déclenchement 6 destinée à coopérer avec le doigt de déclenchement 3 et traversant une lumière 7 dudit doigt de déclenchement 3. La lumière 7 et la goupille de déclenchement 6 sont agencées pour déterminer deux positions du doigt de déclenchement 3 sur la bascule de déclenchement 2, une première position dite inactive lorsque la goupille de déclenchement 6 se trouve dans une première portion 7.1 de la lumière 7 et une seconde position dite active lorsque la goupille de déclenchement 6 se trouve dans une seconde portion 7.2 de la lumière 7. Dans la position active du doigt de déclenchement 3, l'extrémité active 3.1 dudit doigt se trouve dans le chemin de la palette de déclenchement 9.1 du râteau 9 tandis que dans la position inactive du doigt de déclenchement 3, son extrémité active 3.1 ne se trouve pas dans le chemin de la palette de déclenchement 9.1 du râteau 9 et ne peut donc pas entraîner ledit râteau.The lever 4 carries a trigger pin 6 intended to cooperate with the trigger finger 3 and passing through a slot 7 of said trigger finger 3. The slot 7 and the trigger pin 6 are arranged to determine two positions of the trigger finger 3 on the trigger rocker 2, a first so-called inactive position when the trigger pin 6 is located in a first portion 7.1 of the light 7 and a second so-called active position when the trigger pin 6 is located in a second portion 7.2 of the light 7. In the active position of the trigger finger 3, the active end 3.1 of said finger is in the path of the trigger paddle 9.1 of the rake 9 while in the inactive position of the trigger finger 3, its active end 3.1 does not is not in the path of the release pallet 9.1 of the rake 9 and therefore cannot drive said rake.

La figure 1 illustre le mécanisme d'animation au repos. Dans cette position de repos, la came de commande 1 est immobile et l'extrémité active 2.1 de la bascule de déclenchement 2 est en appui contre la came de commande 1, plus précisément en appui entre deux dents de la came de commande 1. Le levier 4 est quant à lui en appui contre une face (a dans la forme d'exécution illustrée aux figures) de la came de réserve de marche 5. La goupille de déclenchement 6 se trouve dans la première portion 7.1 de la lumière 7 du doigt de déclenchement 3, première portion 7.1 qui définit la position inactive dudit doigt de déclenchement 3. Dans cette position inactive du doigt de déclenchement 3, son extrémité active 3.1 n'est pas dans le chemin de la palette de déclenchement 9.1 du râteau 9.The figure 1 illustrates the idle animation mechanism. In this rest position, the control cam 1 is stationary and the active end 2.1 of the trigger rocker 2 bears against the control cam 1, more precisely bears between two teeth of the control cam 1. The lever 4 is for its part bearing against a face (a in the embodiment illustrated in the figures) of the power reserve cam 5. The trigger pin 6 is located in the first portion 7.1 of the slot 7 of the finger trigger 3, first portion 7.1 which defines the inactive position of said trigger finger 3. In this inactive position of the trigger finger 3, its active end 3.1 is not in the path of the trigger paddle 9.1 of the rake 9.

Dans cette position de repos, la came de réserve de marche 5 est entraînée par le mécanisme indicateur de réserve de marche et pivote donc en fonction de la réserve de marche du barillet d'animation. En pivotant, la came de réserve de marche 5 entraîne le levier 4 et la goupille de déclenchement 6. La lumière 7 est en particulier conformée pour que, dans cette position de repos du mécanisme, la goupille de déclenchement 6 puisse se déplacer dans la première portion 7.1 de la lumière 7 sans faire pivoter le doigt de déclenchement 3 dans sa position active.In this rest position, the power reserve cam 5 is driven by the power reserve indicator mechanism and therefore pivots according to the power reserve of the animation barrel. By pivoting, the power reserve cam 5 drives the lever 4 and the release pin 6. The aperture 7 is shaped in particular so that, in this rest position of the mechanism, the release pin 6 can move in the first portion 7.1 of light 7 without rotating trigger finger 3 into its active position.

Le déclenchement du mécanisme d'animation selon l'invention peut être commandé soit à la demande, soit au passage (de l'heure, de la minute...) ou encore aléatoirement. Lors d'une première phase (figure 2) marquant le début du déclenchement, la came de commande 1 pivote (dans le sens horaire sur les figures) entraînée par le barillet d'animation. La came de commande 1 entraîne elle-même la bascule de déclenchement 2 qui pivote en P dans un premier sens contre l'action de son sautoir. De par la forme de la came de commande 1 et de sa denture, l'extrémité active 2.1 de la bascule de déclenchement 2 se lève et sort de l'espace entre deux dents de la came de commande 1. Le doigt de déclenchement 3 reste en position inactive et se déplace par rapport à la goupille de déclenchement 6 du levier 4 qui reste immobile. Cette première phase se poursuit jusqu'à ce qu'une extrémité de la première portion 7.1 de la lumière 7 vienne en butée contre la goupille de déclenchement 6 comme illustré à la figure 2.The triggering of the animation mechanism according to the invention can be controlled either on demand, or on passage (of the hour, of the minute, etc.) or even randomly. During a first phase ( picture 2 ) marking the start of triggering, the control cam 1 pivots (clockwise in the figures) driven by the animation barrel. The control cam 1 itself drives the trigger rocker 2 which pivots in P in a first direction against the action of its jumper. Due to the shape of the control cam 1 and its teeth, the active end 2.1 of the trigger rocker 2 rises and leaves the space between two teeth of the control cam 1. The finger trigger 3 remains in the inactive position and moves relative to trigger pin 6 of lever 4 which remains stationary. This first phase continues until one end of the first portion 7.1 of the light 7 comes into abutment against the trigger pin 6 as illustrated in figure 2 .

Une seconde phase du déclenchement commence alors durant laquelle la came de commande 1 poursuit sa rotation entraînant toujours la bascule de déclenchement 2 dans un premier sens contre l'action de son sautoir pour finir sa montée. Comme la première portion 7.1 de la lumière 7 du doigt de déclenchement 3 est en butée contre la goupille de déclenchement 6, le pivotement de la bascule de déclenchement 2 entraîne le levier 4 qui pivote également en P. L'extrémité active 4.1 du levier 4 s'éloigne alors de la came de réserve de marche 5.A second phase of triggering then begins during which the control cam 1 continues its rotation still driving the trigger rocker 2 in a first direction against the action of its jumper to finish its ascent. As the first portion 7.1 of the opening 7 of the trigger finger 3 is in abutment against the trigger pin 6, the pivoting of the trigger rocker 2 drives the lever 4 which also pivots in P. The active end 4.1 of the lever 4 then moves away from the power reserve cam 5.

Une goupille de blocage 8 fixe est située de sorte que lors de la rotation de la bascule de déclenchement 2 dans le premier sens contre l'action de son sautoir, le doigt de déclenchement 3 vient en butée contre ladite goupille de blocage 8. La poursuite de la rotation de la bascule de déclenchement 2 dans le premier sens contre l'action de son sautoir force alors le doigt de déclenchement 3 à se déplacer dans sa position active. C'est-à-dire que sous l'effet de la rotation de la bascule de déclenchement 2 et du blocage par la goupille de blocage 8, le doigt de déclenchement 3 pivote jusqu'à ce que la goupille de déclenchement 6 rejoigne la seconde portion 7.2 de la lumière 7 qui détermine la seconde position active dudit doigt de déclenchement 3. Cette position est illustrée à la figure 3. Dans la forme d'exécution illustrée, le doigt de déclenchement 3 vient en butée contre la goupille de blocage 8 un peu avant la fin de la montée de la bascule de déclenchement 2.A fixed locking pin 8 is located so that when the trigger rocker 2 rotates in the first direction against the action of its jumper, the trigger finger 3 comes into abutment against said locking pin 8. The pursuit the rotation of the trigger rocker 2 in the first direction against the action of its jumper then forces the trigger finger 3 to move into its active position. That is to say that under the effect of the rotation of the trigger rocker 2 and the blocking by the blocking pin 8, the trigger finger 3 pivots until the trigger pin 6 joins the second portion 7.2 of slot 7 which determines the second active position of said trigger finger 3. This position is illustrated in picture 3 . In the illustrated embodiment, the trigger finger 3 comes into abutment against the locking pin 8 a little before the end of the rise of the trigger rocker 2.

La troisième phase du déclenchement du mécanisme d'animation selon l'invention débute avec la chute de la bascule de déclenchement 2. A la fin de la seconde phase du déclenchement, la bascule de déclenchement 2 a terminé sa montée et rejoint une position dans laquelle elle n'est plus ni retenue ni entraînée par la came de commande 1. Sous l'action de son sautoir, la bascule de déclenchement 2 pivote alors en P dans un second sens opposé au premier. Le doigt de déclenchement 3 est dans sa position active et dans cette position, se trouve dans le chemin de la palette de déclenchement 9.1 du râteau 9. La chute de la bascule de déclenchement 2 entraîne le doigt de déclenchement 3 qui, dans sa position active, va alors entraîner à son tour le râteau 9 qui pivote en A. Le râteau 9 déclenche alors l'animation via sa denture 9.2 reliée cinématiquement à l'objet à animer.The third phase of the triggering of the animation mechanism according to the invention begins with the fall of the trigger rocker 2. At the end of the second phase of the triggering, the trigger rocker 2 has completed its mounted and reaches a position in which it is no longer retained or driven by the control cam 1. Under the action of its jumper, the trigger rocker 2 then pivots in P in a second direction opposite to the first. The trigger finger 3 is in its active position and in this position is in the path of the trigger pallet 9.1 of the rake 9. The fall of the trigger rocker 2 drives the trigger finger 3 which, in its active position , will then in turn drive the rake 9 which pivots at A. The rake 9 then triggers the animation via its toothing 9.2 kinematically connected to the object to be animated.

La lumière 7 et la goupille de déclenchement 6 sont en outre conformées pour que, en pivotant dans le second sens (chute) et avec le doigt de déclenchement 3 dans sa position active (goupille de déclenchement 6 dans la seconde portion 7.2 de la lumière 7), la bascule de déclenchement 2 entraîne également le levier 4 qui pivote en P jusqu'à ce que son extrémité active 4.1 vienne en appui contre la came de réserve de marche 5. Une fois en appui contre la came de réserve de marche 5, le levier 4 et sa goupille de déclenchement 6 sont immobilisés. Cette position est illustrée à la figure 4.The light 7 and the trigger pin 6 are also shaped so that, by pivoting in the second direction (fall) and with the trigger finger 3 in its active position (trigger pin 6 in the second portion 7.2 of the light 7 ), the trigger rocker 2 also drives the lever 4 which pivots in P until its active end 4.1 bears against the power reserve cam 5. Once it bears against the power reserve cam 5, lever 4 and its trigger pin 6 are immobilized. This position is illustrated in figure 4 .

Alors commence la dernière phase du déclenchement. Comme illustré sur la figure 4, la bascule de déclenchement 2 n'a pas fini sa chute et n'est pas encore revenue au contact de la came de commande 1. Elle continue donc de pivoter dans le second sens sous l'action de son sautoir, entraînant avec elle le doigt de déclenchement 3 qui est dans sa position active. Cependant, la goupille de déclenchement 6 est immobile. De par la forme de la lumière 7, la goupille de déclenchement 6 va alors contraindre le doigt de déclenchement 3 à pivoter pour rejoindre sa première position inactive (figure 5) dans laquelle la goupille de déclenchement 6 se trouve dans la première portion 7.1 de la lumière 7. Ce faisant, l'extrémité active 3.1 du doigt de déclenchement 3 sort du chemin de la palette de déclenchement 9.1 du râteau 9 et n'entraîne alors plus le râteau 9. La bascule de déclenchement 2 termine sa chute sous l'action de son sautoir jusqu'à retrouver sa position en appui contre la came de commande 1. Le mécanisme a retrouvé sa position de repos illustrée à la figure 1.Then begins the last phase of triggering. As illustrated on the figure 4 , the trigger rocker 2 has not finished its fall and has not yet come back into contact with the control cam 1. It therefore continues to pivot in the second direction under the action of its jumper, carrying with it the trigger finger 3 which is in its active position. However, the trigger pin 6 is stationary. Due to the shape of slot 7, trigger pin 6 will then force trigger finger 3 to pivot to reach its first inactive position ( figure 5 ) in which the trigger pin 6 is located in the first portion 7.1 of the light 7. In doing so, the active end 3.1 of the trigger finger 3 leaves the path of the trigger pallet 9.1 of the rake 9 and does not then cause plus the rake 9. The trigger rocker 2 completes its fall under the action of its jumper until return to its resting position against control cam 1. The mechanism has returned to its rest position illustrated in figure 1 .

Ainsi, dans cette forme d'exécution, la course de déclenchement durant laquelle le doigt de déclenchement 3 est dans sa position active et entraîne le râteau 9 via sa palette de déclenchement 9.1 est déterminée par le levier 4 qui vient prendre l'information concernant la réserve de marche du barillet d'animation sur la came de réserve de marche 5. L'amplitude de la rotation du râteau 9 et donc les mouvements de l'objet à animer ou l'animation dépendent donc de la réserve de marche du barillet d'animation.Thus, in this embodiment, the trigger stroke during which the trigger finger 3 is in its active position and drives the rake 9 via its trigger paddle 9.1 is determined by the lever 4 which takes the information concerning the power reserve of the animation barrel on the power reserve cam 5. The amplitude of the rotation of the rake 9 and therefore the movements of the object to be animated or the animation therefore depend on the power reserve of the barrel d 'animation.

Ainsi, dans la forme d'exécution illustrée, chaque face a, b, c , d, e de la came de réserve de marche 5 détermine une amplitude de rotation du râteau 9 différente et par conséquent, dans chacun des cinq états de la réserve de marche déterminés par lesdites faces a, b, c, d, e, l'animation de l'objet est déclenchée à un rythme ou à une fréquence diffèrent.Thus, in the embodiment illustrated, each face a, b, c, d, e of the power reserve cam 5 determines a different amplitude of rotation of the rake 9 and consequently, in each of the five states of the power reserve walking determined by said faces a, b, c, d, e, the animation of the object is triggered at a different rate or frequency.

La came de réserve de marche 5 pourrait également être agencée pour définir un état de la réserve de marche dans lequel le râteau 9 n'est pas pivoté (amplitude du mouvement nulle) et l'animation n'a pas lieu, par exemple si la réserve de marche est trop faible.The power reserve cam 5 could also be arranged to define a state of the power reserve in which the rake 9 is not pivoted (zero amplitude of movement) and the animation does not take place, for example if the power reserve is too low.

La présente forme d'exécution a été décrite à titre d'exemple. De manière générale, le mécanisme d'animation selon l'invention est agencé pour faire varier le rythme ou la fréquence de l'animation, c'est-à-dire de son déclenchement, en fonction de la réserve de marche de l'organe moteur du mécanisme. Ainsi, les moments de déclenchement de l'animation de l'objet vont dépendre de la réserve de marche de l'organe moteur du mécanisme d'animation. Le mécanisme d'animation comprend notamment :

  • un organe moteur pour fournir l'énergie destinée à l'animation de l'objet ;
  • une came de réserve de marche indexée à la réserve de marche de l'organe moteur et déterminant au moins deux positions ou états de ladite réserve de marche ;
  • un mobile de commande relié cinématiquement à l'organe moteur et destiné à commander le déclenchement de l'animation ;
  • un dispositif de déclenchement commandé par le mobile de commande et relié cinématiquement à la came de réserve de marche.
This embodiment has been described by way of example. In general, the animation mechanism according to the invention is arranged to vary the rhythm or the frequency of the animation, that is to say of its triggering, as a function of the power reserve of the organ mechanism motor. Thus, the instants of triggering of the animation of the object will depend on the power reserve of the driving member of the animation mechanism. The animation mechanism includes:
  • a motor member to supply the energy intended for the animation of the object;
  • a power reserve cam indexed to the power reserve of the driving member and determining at least two positions or states of said power reserve;
  • a control mobile connected kinematically to the motor member and intended to control the triggering of the animation;
  • a trigger device controlled by the mobile control and kinematically connected to the power reserve cam.

Le mécanisme d'animation et ses composants sont de préférence agencés pour qu'à chaque déclenchement de l'animation, le mobile de commande entraîne le dispositif de déclenchement et que la position d'un organe du dispositif de déclenchement soit influencée par la came de réserve de marche, ladite position influençant à son tour le rythme ou la fréquence de l'animation de l'objet.The animation mechanism and its components are preferably arranged so that each time the animation is triggered, the control wheel drives the trigger device and the position of a component of the trigger device is influenced by the power reserve, said position in turn influencing the rhythm or frequency of the animation of the object.

A titre d'exemple, le mécanisme d'animation peut être agencé pour que quand la réserve de marche du barillet d'animation est au-dessus d'un seuil prédéterminé, l'objet d'animation est commandé en un mouvement cyclique N fois (où N ≥ 2), et quand la réserve de marche du barillet d'animation est en dessous de ce seuil, l'objet d'animation est commandé en ce mouvement cyclique une seule fois.By way of example, the animation mechanism can be arranged so that when the power reserve of the animation barrel is above a predetermined threshold, the animation object is controlled in a cyclic movement N times (where N≥2), and when the power reserve of the animation barrel is below this threshold, the animation object is controlled in this cyclic movement only once.
