Description

La présente invention se rapporte aux mouvements de montre du type comportant un organe mobile visible et assurant une animation de l'affichage.The present invention relates to watch movements of the type comprising a visible movable member and providing an animation of the display.

De manière plus précise, la présente invention concerne un mouvement de montre de type mécanique, comportant un bâti et, portés par le bâti :

  • un rouage de finissage comprenant une pluralité de roues et entraîné périodiquement en rotation par un organe moteur,
  • un mobile animé d'un mouvement pulsé,
  • une pièce d'animation destinée à être visible et agencée de manière à être animée d'un mouvement périodique,
  • un organe de commande de la pièce d'animation, et
  • un rouage d'animation en prise avec un mobile du rouage de finissage et entraînant l'organe de commande.
More specifically, the present invention relates to a watch movement of the mechanical type, comprising a frame and, carried by the frame:
  • a work train comprising a plurality of wheels and periodically driven in rotation by a motor member,
  • a mobile animated with a pulsating movement,
  • an animation piece intended to be visible and arranged so as to be animated with a periodic movement,
  • a control member of the animation piece, and
  • an animation wheel in engagement with a mobile of the work train and driving the control member.

Un mouvement de montre de ce type est, par exemple, décrit dans le brevet CH 30.220, qui propose d'animer une figurine au moyen d'une roue reliée au rouage de finissage comportant des dents de loups. Ces dernières entraînent périodiquement une tige partie de l'automate. Une telle solution a pour inconvénient que le mouvement de l'automate est saccadé, à cause des sauts sur les dents de loups.A watch movement of this type is, for example, described in the patent CH 30.220, which proposes to animate a figurine by means of a wheel connected to the work train comprising wolf teeth. These last periodically cause a rod part of the automaton. Such a solution has the disadvantage that the movement of the automaton is jerky, because of jumps on the teeth of wolves.

On connaît, par ailleurs, des montres telles que celle décrite dans le document FR 630.190, dans lesquelles une image de pendule est fixée sur l'ancre de l'échappement. De la sorte, à chaque alternance, cette image se déplace brusquement. Ici aussi, le mouvement est saccadé et donc plus énervant qu'apaisant.Also known are watches such as that described in FR 630.190, in which a pendulum image is fixed on the anchor of the exhaust. In this way, at each alternation, this image moves abruptly. Here too, the movement is jerky and therefore more annoying than appeasing.

Le but de la présente invention est de réaliser une animation dans laquelle les saccades dues au mouvement pulsé de l'échappement ou du moteur pas à pas sont amorties pour que le mouvement de l'automate soit uniforme et sans à coup. A cet effet, le mouvement de montre selon l'invention est caractérisé en ce que le rouage d'animation, l'organe de commande et la pièce d'animation sont agencés de manière à ce que le mouvement périodique présente un mouvement d'oscillation sinusoïdal.The object of the present invention is to provide an animation in which the saccades due to the pulsed movement of the escapement or stepping motor are damped so that the movement of the automaton is uniform and smooth. For this purpose, the watch movement according to the invention is characterized in that the work train, the control member and the workpiece are arranged so that the periodic movement exhibits a sinusoidal oscillation movement.

Afin d'obtenir une qualité de la simulation aussi bonne que possible, un organe élastique est intercalé entre le mobile du rouage de finissage avec lequel le rouage d'animation est en prise et la pièce d'animation, formant ainsi un filtre mécanique, par la combinaison de l'organe élastique avec l'inertie des mobiles du rouage d'animation, de l'organe de commande et de la pièce d'animation.In order to obtain a simulation quality that is as good as possible, an elastic member is interposed between the mobile of the finishing gear train with which the animation wheel is engaged and the animation piece, thus forming a mechanical filter, by the combination of the elastic member with the inertia of the mobiles of the animation wheel, the control member and the animation piece.

Du point de vue de la disposition des différents composants, il apparaît comme avantageux que le rouage d'animation soit relié au rouage de finissage par son mobile de secondes. Dans ce cas, le rouage d'animation est agencé de manière à accélérer la vitesse de rotation du mobile de secondes vers le mobile coopérant avec la pièce d'animation.From the point of view of the arrangement of the various components, it appears advantageous that the animation wheel is connected to the work train by its mobile seconds. In this case, the animation wheel is arranged to accelerate the speed of rotation of the second mobile to the mobile cooperating with the animation part.

De manière avantageuse, la pièce d'animation oscille à une fréquence comprise entre 0,2 et 2 Hz.Advantageously, the animation piece oscillates at a frequency of between 0.2 and 2 Hz.

Dans un mode particulier de réalisation le mouvement comporte, en outre, un levier. Le dernier mobile du rouage d'animation est muni d'une planche. De plus, la pièce d'animation et la planche sont munies de moyens de liaison disposés excentriquement et agencés pour être reliés chacun à l'une des extrémités du levier, pour former ensemble une bielle reliant le rouage d'animation à la pièce d'animation.In a particular embodiment, the movement comprises, in addition, a lever. The last mobile of the animation wheel is equipped with a board. In addition, the animation piece and the board are provided with connecting means arranged eccentrically and arranged to be each connected to one end of the lever, to form together a connecting rod connecting the animation train to the workpiece. animation.

Dans une première variante, le levier présente, sur une part au moins de sa longueur, une structure déformable élastiquement, agencée de manière à constituer ledit organe élastique.In a first variant, the lever has, on at least part of its length, an elastically deformable structure, arranged so as to constitute said elastic member.

Dans une deuxième variante, l'organe élastique relie élastiquement deux mobiles coaxiaux du rouage d'animation.In a second variant, the elastic member elastically connects two coaxial mobiles of the animation train.

De manière avantageuse, l'organe élastique forme, avec la pièce d'animation et le/les mobiles du rouage interposés entre celui coopérant avec la pièce d'animation et celui relié à l'organe élastique, un système oscillant dont la période est comprise entre celle définie par la périodicité de l'avancement du rouage de finissage et celle du mouvement alternatif de ladite pièce.Advantageously, the elastic member forms, with the piece of animation and the mobile of the gear train interposed between that cooperating with the animation piece and that connected to the elastic member, an oscillating system whose period is between that defined by the periodicity of the advancement of the gear train and that of the reciprocating movement of said workpiece.

Afin que la pièce d'animation soit aussi insensible que possible aux chocs, elle est montée pivotante sur le bâti et son centre de gravité se trouve sensiblement sur son axe de pivotement.So that the animation piece is as insensitive as possible to shocks, it is pivotally mounted on the frame and its center of gravity is substantially on its pivot axis.

Pour permettre l'utilisation d'un calibre de montre déjà existant, le bâti du mouvement selon l'invention comporte :

  • une première platine et un premier pont entre lesquels pivotent les mobiles du rouage de finissage, et
  • une deuxième platine sur laquelle pivotent les mobiles du rouage d'animation et la pièce d'animation, la platine, le rouage d'animation et la pièce d'animation formant ensemble un module indépendant pouvant être fixé par la deuxième platine sur la première platine.
To allow the use of an already existing watch gauge, the frame of the movement according to the invention comprises:
  • a first plate and a first bridge between which rotate the wheels of the finishing gear, and
  • a second stage on which the mobiles of the animation wheel and the animation piece pivot, the plate, the animation wheel and the animation piece together forming an independent module that can be fixed by the second plate on the first plate .

Il est bien évident que tout ou partie du rouage d'animation peut pivoter également dans un pont, lequel est fixé sur la deuxième platine.It is obvious that all or part of the animation wheel can also pivot in a bridge, which is fixed on the second plate.

D'autres avantages et caractéristiques de l'invention ressortiront de la description qui va suivre, faite en regard du dessin annexé, dans lequel :

La montre représentée sur la figure 1 comporte une boîte 10 définissant un logement dans lequel est disposé un mouvement de montre qui sera décrit en référence aux figures 2 à 5, lequel comporte un rouage de finissage et un rouage de minuterie qui portent respectivement des aiguilles de secondes 12, de minutes 14 et d'heures 16. Un cadran 18 est intercalé entre le mouvement et les aiguilles. Il est percé d'une fenêtre 20 au travers de laquelle apparaît une pièce d'animation 22 agencée de manière à simuler le mouvement d'un pendule, comme cela sera expliqué ci-dessous.The watch shown in FIG. 1 comprises a box 10 defining a housing in which a watch movement is arranged, which will be described with reference to FIGS. 2 to 5, which comprises a finishing train and a timer train carrying respectively 12 seconds, 14 minutes and 16 hours. A dial 18 is interposed between the movement and the hands. It is pierced by a window 20 through which appears an animation piece 22 arranged to simulate the movement of a pendulum, as will be explained below.

La figure 2 montre, vu de dessus, un mouvement de montre 24 selon l'invention, tel que celui logé dans la boîte 10. Le cadran a été retiré. Les aiguilles 12, 14 et 16 sont visibles en transparence. La pièce d'animation 22 est également apparente. Ses positions extrêmes sont représentées en pointillé.Figure 2 shows, seen from above, a watch movement 24 according to the invention, such as that housed in the box 10. The dial has been removed. The needles 12, 14 and 16 are visible in transparency. The animation piece 22 is also apparent. Its extreme positions are represented in dashed lines.

Le mouvement 24 comporte un calibre de base 26, représenté schématiquement vu de côté sur la figure 3, assurant les fonctions essentielles d'une pièce d'horlogerie, soit la fourniture d'énergie, la génération d'une fréquence de base, la division mécanique au moyen de rouages ainsi que les fonctions de correction. Sa base de temps peut aussi bien être un quartz qu'un balancier-spiral.The movement 24 comprises a base gauge 26, shown diagrammatically in side view in FIG. 3, providing the essential functions of a timepiece, namely the supply of energy, the generation of a basic frequency, the division mechanics by means of cogs as well as correction functions. His time base can be both a quartz and a sprung balance.

Le calibre 26 est notamment muni d'une platine et d'un pont non référencés et d'un rouage de finissage comportant des mobiles qui sont montés pivotants entre la platine et le pont, seule l'extrémité du mobile des secondes 30 étant visible sur la figure 3. Un rouage de minuterie, qui n'est pas non plus représenté, porte et assure l'entraînement des aiguilles des minutes 14 et des heures 16.The caliber 26 is in particular provided with a plate and a bridge not referenced and a finishing gear comprising mobiles which are pivotally mounted between the plate and the bridge, only the end of the mobile of the seconds 30 being visible on Figure 3. A timer wheel, which is not shown either, carries and ensures the training of minute hands 14 and hours 16.

Le calibre de base 26 porte un module 32 comportant une platine 34 et un pont 36 qui, ensemble, servent de support à un rouage d'animation 38. Ce dernier comporte trois mobiles 40, 42 et 44, chacun formé d'un pignon identifié par la lettre a, et d'une roue identifiée par la lettre b, à l'exception du mobile 44 qui comporte un pignon 44a et une planche 44c, mais pas de roue.The base gauge 26 carries a module 32 comprising a plate 34 and a bridge 36 which, together, serve as support for an animation wheel 38. The latter comprises three mobiles 40, 42 and 44, each formed of a pinion identified by the letter a , and a wheel identified by the letter b , with the exception of the mobile 44 which comprises a pinion 44a and a board 44c, but no wheel.

Le mobile 40 est coaxial à la roue de secondes 30. Son pignon 40a est muni d'un trou engagé dans l'extrémité du mobile des secondes 30, le trou et l'extrémité étant agencés de manière à ce que les mobiles 30 et 40 soient solidaires en rotation, par exemple grâce à un lanternage pratiqué sur le pignon 40a, le mobile 40 étant alors chassé sur l'extrémité du mobile 30.The mobile 40 is coaxial with the seconds wheel 30. Its pinion 40a is provided with a hole engaged in the end of the mobile seconds 30, the hole and the end being arranged so that the mobile 30 and 40 are integral in rotation, for example by means of a lanterning made on the pinion 40a, the mobile 40 being then driven on the end of the mobile 30.

La roue 40b entraîne le pignon 42a et, avec lui, la roue 42b, laquelle engrène avec le pignon 44a du mobile 44.The wheel 40b drives the pinion 42a and, with it, the wheel 42b, which meshes with the pinion 44a of the mobile 44.

Les mobiles 40, 42 et 44 sont nombrés de manière à ce que la vitesse de rotation du mobile 44 soit de l'ordre de 1 tour par seconde, typiquement compris entre 0,2 et 2 tours par secondes.The mobiles 40, 42 and 44 are numbered so that the rotational speed of the mobile 44 is of the order of 1 turn per second, typically between 0.2 and 2 revolutions per second.

Les mobiles 40 et 42, ainsi que le pignon 44a, sont disposés et pivotent entre la platine 34 et le pont 36. Ainsi qu'on peut le voir sur la figure 5, le pignon 44a est muni d'un pivot 44d dépassant du pont 36 et sur lequel est chassée la planche 44c. Cette dernière porte une tige 44e, dont la fonction sera précisée plus loin.The mobiles 40 and 42, as well as the pinion 44a, are arranged and pivoted between the plate 34 and the bridge 36. As can be seen in FIG. 5, the pinion 44a is provided with a pivot 44d protruding from the bridge 36 and on which the board 44c is driven. The latter carries a stem 44e, whose function will be specified later.

La pièce d'animation 22 comporte une portion centrale 22a (fig. 2) munie d'un trou dans lequel est chassé un arbre 22b monté pivotant entre la platine 34 et le pont 36, au voisinage du centre du mouvement. Deux bras 22c et 22d s'étendent de part et d'autre de la portion centrale 22a. L'extrémité libre du bras 22c porte une lentille 22d apparente au travers de la fenêtre 20 et simulant la lentille d'un pendule. L'extrémité de l'autre bras 22d est munie d'une tige 22e, mieux visible sur la figure 5 et destinée à assurer une liaison avec la planche 44c, par un levier 46 monté pivotant sur les tiges 44e et 22e. Ainsi, le mobile 44 et le levier 46 forment ensemble un organe de commande de la pièce d'animation 22.The animation piece 22 comprises a central portion 22a (FIG 2) provided with a hole in which is driven a shaft 22b pivotally mounted between the plate 34 and the bridge 36, near the center of the movement. Two arms 22c and 22d extend on either side of the central portion 22a. The free end of the arm 22c carries a lens 22d apparent through the window 20 and simulating the lens of a pendulum. The end of the other arm 22d is provided with a rod 22e, better visible in Figure 5 and intended to provide a connection with the board 44c, by a lever 46 pivotally mounted on the rods 44e and 22e. Thus, the mobile 44 and the lever 46 together form a control member of the animation piece 22.

Le levier 46 porte deux pierres d'horlogerie 46a et 46b, chassées respectivement à l'une et l'autre de ses extrémités et coopérant l'une avec la tige 22e, l'autre avec la tige 44e. Il présente, dans sa partie médiane 46c, une structure en méandres lui conférant une plus grande élasticité que celle d'un barreau droit.The lever 46 carries two clockwork stones 46a and 46b, respectively driven at one and the other of its ends and cooperating one with the rod 22e, the other with the rod 44e. It has, in its middle part 46c, a meandering structure giving it greater elasticity than that of a straight bar.

Le levier 46 est maintenu sur les tiges 22e et 44e par des manchons 48 chassés sur les tiges 22e et 44e, laissant un espace suffisant avec les pierres 46a et 46b pour que celles-ci ne soient pas entravées dans leur mouvement.The lever 46 is held on the rods 22e and 44e by sleeves 48 driven on the rods 22e and 44e, leaving sufficient space with the stones 46a and 46b so that they are not impeded in their movement.

Le mobile 44 et le levier 46 forment ainsi ensemble un système à bielle entraînant la pièce d'animation 22.The mobile 44 and the lever 46 together form a rod system driving the animation part 22.

Dans la montre telle qu'elle vient d'être décrite, lorsqu'elle est de type à balancier-spiral, la roue de secondes effectue un léger saut chaque fois que l'échappement donne une impulsion au balancier. Cela se produit à chaque demi-oscillation, soit de 5 à 10 fois par seconde. Cette fréquence est trop basse pour simuler un mouvement continu. Dans la pratique, la durée de l'impulsion est de l'ordre de 1% du temps de la demi-période. Pour que le pendule donne l'illusion d'avoir un mouvement continu et sinusoïdal, il est nécessaire d'introduire un organe amortissant le mouvement. C'est la fonction de la structure en méandres 46c, qui confère une plus grande élasticité au levier 46.In the watch as just described, when it is sprung-balance type, the seconds wheel makes a slight jump each time the escapement gives an impulse to the balance. This occurs at each half oscillation, 5 to 10 times per second. This frequency is too low to simulate a continuous movement. In practice, the duration of the pulse is of the order of 1% of the time of the half-period. For the pendulum to give the illusion of having a continuous sinusoidal movement, it is necessary to introduce an organ damping the movement. This is the function of the meandering structure 46c, which gives the lever 46 greater elasticity.

En variante, la structure élastique 46c du levier 46 pourrait être remplacée en montant libre en rotation la roue 42b sur le pignon 42a et en les reliant par un ressort-spiral. Cette variante n'a pas été représentée au dessin, car facilement réalisable par un homme du métier.Alternatively, the elastic structure 46c of the lever 46 could be replaced by freely rotating the wheel 42b on the pinion 42a and connecting them by a spiral spring. This variant has not been shown in the drawing, as easily achievable by a person skilled in the art.

Afin d'obtenir une simulation aussi bonne que possible, la période de l'ensemble formé par la pièce d'animation 22 et l'organe élastique 46b est comprise entre celle définie par la périodicité de l'avancement du rouage de finissage et celle du mouvement oscillant de la pièce d'animation 22.In order to obtain a simulation as good as possible, the period of the assembly formed by the animation piece 22 and the elastic member 46b is between that defined by the periodicity of the progress of the finishing gear and that of the oscillating motion of the animation piece 22.

De manière avantageuse, et pour que le mouvement d'oscillation de la pièce d'animation 22 subisse un minimum de perturbations, l'ensemble formé par le levier 46 et la pièce d'animation 22 est équilibré, c'est à dire que son centre de gravité se trouve sensiblement sur l'axe de pivotement de la pièce 22.Advantageously, and for the oscillation movement of the animation piece 22 to undergo a minimum of disturbances, the assembly formed by the lever 46 and the animation piece 22 is balanced, that is to say that its center of gravity is substantially on the pivot axis of the piece 22.

La façon d'assurer la liaison de la pièce d'animation 22 avec le rouage d'animation 38 pourrait être faite par d'autres moyens que ceux représentés et décrits. Il est ainsi possible de réaliser une pièce d'animation dont le bras 22d serait considérablement raccourci et porterait un plot. Le levier 46 serait remplacé par un ressort fin, fixé sur le plot du levier 22d. L'autre extrémité du ressort serait munie d'une protubérance dans laquelle serait chassée une pierre similaire à celle portant la référence 46b. De la sorte, il serait possible d'avoir un organe élastique plus souple.The way to ensure the connection of the animation part 22 with the animation wheel 38 could be made by other means than those shown and described. It is thus possible to produce an animation piece whose arm 22d would be considerably shortened and carry a stud. The lever 46 would be replaced by a thin spring, fixed on the stud of the lever 22d. The other end of the spring would be provided with a protuberance in which would be driven a stone similar to that bearing the reference 46b. In this way, it would be possible to have a more flexible elastic member.

Il va de soi que la pièce d'animation pourrait également présenter une autre forme que celle d'un pendule, avec sa verge et sa lentille, sans pour autant sortir du cadre de l'invention. La pièce d'animation pourrait ainsi avoir la forme d'un bateau, le mouvement oscillant simulant le mouvement des vagues, ou de tout autre objet effectuant un mouvement pendulaire lent.It goes without saying that the animation piece could also have a shape other than that of a pendulum, with its rod and its lens, without departing from the scope of the invention. The animation piece could thus have the shape of a boat, the oscillating movement simulating the movement of waves, or any other object performing a slow pendulum movement.

Il est, bien sûr, aussi possible d'intégrer les composants assurant l'entraînement de la pièce d'animation directement sur la platine du calibre de base.It is, of course, also possible to integrate the components for driving the animation part directly on the plate of the basic template.

Le mode de réalisation représenté sur la figure 6 permet d'améliorer encore le lissage du mouvement de l'automate. Sur cette figure, seuls les mobiles ont été représentés. Il va de soi qu'ils pivotent dans le bâti du mouvement, généralement entre un pont et la platine. Dans ce mode de réalisation, l'organe moteur, qui fournit l'énergie au rouage de finissage, est formé d'un ressort de barillet, logé dans un barillet 50, constituant le premier mobile du rouage de finissage, ce dernier entraînant un échappement et un balancier-spiral, qui forment ensemble un organe à mouvement pulsé. Le rouage d'animation comporte cinq mobiles 52, 54, 56, 58 et 60.The embodiment shown in FIG. 6 makes it possible to further improve the smoothing of the movement of the automaton. In this figure, only the mobiles have been represented. It goes without saying that they rotate in the frame of the movement, generally between a bridge and the plate. In this embodiment, the drive member, which supplies the energy to the finishing gear train, is formed of a mainspring, housed in a cylinder 50, constituting the first mobile of the work train, the latter driving an exhaust and a balance-spring, which together form a pulsed movement member. The animation wheel comprises five mobiles 52, 54, 56, 58 and 60.

Le mobile 52 comprend un pignon 52a, en prise avec la denture du barillet 50, et une roue 52b qui entraîne le mobile 54 par son pignon 54a. Ce dernier est solidaire d'une virole 54b, fixée par chassage et qui porte un spiral 54c. Une roue 54d est montée folle sur le pignon 54a, tenue en place axialement par une bague 54e chassée sur l'arbre du pignon 54a. Elle est munie d'un piton 54f fixé à l'extrémité du spiral 54c. La fixation du spiral 54c sur la virole 54b et sur le piton 54f se fait de manière classique, par exemple par collage ou soudage. De la sorte, le pignon 54a et la roue 54d sont solidaires en rotation, mais reliées élastiquement l'une à l'autre, amortissant les à-coups dus aux mouvements saccadés du balancier. Il est aussi possible de réaliser le spiral 54c et ses moyens de fixation soit la virole 54b et le piton 54f en une seule pièce, chassée sur le pignon 54a et sur un piton que comporterait la roue 54d.The mobile 52 comprises a pinion 52a, in engagement with the toothing of the barrel 50, and a wheel 52b which drives the mobile 54 by its pinion 54a. The latter is secured to a ring 54b, fixed by driving and carrying a hairspring 54c. A wheel 54d is mounted idle on the pinion 54a, held in place axially by a ring 54e driven on the pinion shaft 54a. It is equipped with a piton 54f attached to the end of the hairspring 54c. Fixing the hairspring 54c on the shell 54b and on the pinon 54f is done conventionally, for example by gluing or welding. In this way, the pinion 54a and the wheel 54d are integral in rotation, but elastically connected to one another, damping jolts due to jerky movements of the balance. It is also possible to produce the hairspring 54c and its fastening means is the ferrule 54b and the pinon 54f in one piece, driven on the pinion 54a and a pin that would include the wheel 54d.

La roue 54d engrène avec le mobile 56 et plus particulièrement avec son pignon 56a, alors que sa roue 56b entraîne le mobile 58 par son pignon 58a. La roue 58b engrène avec le pignon 60a du mobile 60. Ce dernier comporte une planche 60b portant une tige 60c, similaire à la tige 44e, et sur laquelle pivote le levier 46.The wheel 54d meshes with the mobile 56 and more particularly with its pinion 56a, while its wheel 56b drives the mobile 58 by its pinion 58a. The wheel 58b meshes with the pinion 60a of the mobile 60. The latter comprises a board 60b carrying a rod 60c, similar to the rod 44e, and on which the lever 46 pivots.

La planche 60b sera dimensionnée de manière à ce qu'elle forme une masse d'inertie suffisante pour que le spiral 54c reste légèrement armé, de telle sorte que le pendule continue à se mouvoir entre deux alternances du balancier. Le dimensionnement du spiral et de la masse d'inertie sera d'autant plus délicat que l'énergie sera prélevée sur un mobile rapide du train d'engrenages de finissage.The board 60b will be dimensioned so that it forms a sufficient mass of inertia so that the hairspring 54c remains slightly armed, so that the pendulum continues to move between two alternations of the balance. The sizing of the hairspring and the mass of inertia will be all the more difficult as the energy will be taken from a fast mobile of the finishing gear train.

Le prélèvement pourrait être fait également sur la roue de grand-moyenne ou sur la roue de moyenne. Toutefois, en prélevant l'énergie au niveau du barillet, le nombre de mobiles compris entre l'organe animé d'un mouvement pulsé, soit l'échappement, et l'organe simulant un mouvement sinusoïdal, soit le pendule, est tel que leur élasticité est suffisante pour rendre invisible les impulsions du balancier. Il n'est donc pas indispensable d'ajouter un organe élastique supplémentaire, même si la pièce d'animation oscille à une fréquence relativement élevée, par exemple de 2 Hz.Sampling could be done also on the medium-sized wheel or on the average wheel. However, by taking the energy at the barrel, the number of mobiles between the organ animated by a pulsed movement, the escapement, and the organ simulating a sinusoidal movement, or the pendulum, is such that their elasticity is sufficient to make invisible the pulses of the pendulum. It is therefore not essential to add an additional elastic member, even if the animation piece oscillates at a relatively high frequency, for example 2 Hz.

La figure 7 montre un autre mode de réalisation de l'invention, dans lequel le rouage d'animation 38 se limite à une roue 62 disposée sur l'arbre de la roue des secondes du rouage de finissage et le dernier mobile 44 dont le pignon 44a engrène avec la roue 62. La planche 44c entraîne, comme expliqué plus haut, la pièce d'animation 22.FIG. 7 shows another embodiment of the invention, in which the animation wheel 38 is limited to a wheel 62 disposed on the shaft of the second wheel of the finishing gear and the last wheel 44 whose pinion 44a meshes with the wheel 62. The board 44c causes, as explained above, the animation part 22.

Le rapport d'engrenages entre la roue 62 et le pignon 44a est avantageusement de 1/12, de telle sorte que la période de la pièce d'animation est de 5 secondes. Dans ce cas, le mouvement pulsé du rouage de finissage est fortement atténué d'une part à cause du moment d'inertie élevé de la roue 62, d'autre part à cause du très faible déplacement de la pièce d'animation à chaque alternance du balancier.The ratio of gears between the wheel 62 and the gear 44a is advantageously 1/12, so that the period of the animation piece is 5 seconds. In this case, the pulsed movement of the work train is strongly attenuated on the one hand because of the high moment of inertia of the wheel 62, on the other hand because of the very small displacement of the animation part at each alternation of the pendulum.

Afin d'éviter que les ébats d'engrenages du rouage d'animation n'engendrent des mouvements aléatoires de la pièce d'animation, il est possible de munir cette dernière d'un frein travaillant sur l'extrémité d'un pivot de son arbre.In order to prevent the gears of gear of the animation train from causing random movements of the animation piece, it is possible to provide the latter with a brake working on the end of a pivot of its animation. tree.

Dans les exemples décrits ci-dessus, l'organe de commande de la pièce d'animation est de type à manivelle. Le même effet pourrait être obtenu au moyen d'une came et d'un levier en appui contre la came.In the examples described above, the control member of the animation part is of the crank type. The same effect could be obtained by means of a cam and a lever resting against the cam.

Ainsi, grâce aux caractéristiques particulières que présente le mouvement selon l'invention, il est possible de réaliser une montre munie d'une animation lente tendant à apporter une touche de sérénité et de calme, faisant contraste avec les conditions habituelles de la vie de tous les jours, et offrant ainsi au porteur un peu de calme, même lorsqu'il lit l'heure. De plus, la présence d'un rouage permet de mettre le point de pivotement de la pièce d'animation presque n'importe où, et notamment au voisinage immédiat du centre du mouvement, ce qui confère à la montre un aspect esthétique original.Thus, thanks to the particular characteristics of the movement according to the invention, it is possible to make a watch with a slow animation tending to bring a touch of serenity and calm, in contrast with the usual conditions of life of all the days, and thus offering the wearer a little calm, even when reading the time. In addition, the presence of a gear train makes it possible to put the pivot point of the animation piece almost anywhere, and in particular in the immediate vicinity of the center of the movement, which gives the watch an original aesthetic appearance.
