Description

Domaine techniqueTechnical area

La présente invention se rapporte au domaine de l'horlogerie. Elle concerne, plus particulièrement, une pièce d'horlogerie comprenant une représentation d'un objet non rectiligne, cette représentation étant généralement disposée sur un cadran, de manière à être visible par un utilisateur. La représentation est formée notamment d'un élément mobile relié cinématiquement à un mécanisme d'entraînement susceptible d'être entraîné par une source d'énergie.The present invention relates to the field of watchmaking. It relates more particularly to a timepiece comprising a representation of a non-rectilinear object, this representation being generally arranged on a dial, so as to be visible by a user. The representation is formed in particular of a movable element kinematically connected to a drive mechanism capable of being driven by a power source.

Etat de la techniqueState of the art

On sait que l'horlogerie et le monde des automates partagent un certain nombre de points communs techniques. On connaît ainsi dans des pièces nommées « Jaquemart », dans lesquelles un personnage comporte un bras mobile entraîné par un mécanisme d'entraînement lorsque, au passage de l'heure, un système de sonnerie est enclenché. Le bras mobile est alors actionné pour donner l'impression que les sons produits par le système de sonnerie résultent de coups frappés par le personnage, frappant une cloche avec son bras mobile.We know that watchmaking and the world of automata share a certain number of common technical points. Thus known in parts called "Jaquemart", in which a character has a movable arm driven by a drive mechanism when, at the passage of time, a ringing system is engaged. The moving arm is then actuated to give the impression that the sounds produced by the ringing system result from blows struck by the character, striking a bell with his movable arm.

On connaît également des pièces d'horlogerie beaucoup plus simples, dans lesquelles la représentation d'un objet est simplement fixée sur une aiguille des secondes, par exemple, pour être entraîner en continu autour du mouvement.There are also simpler timepieces in which the representation of an object is simply attached to a second hand, for example, to be continuously driven around the movement.

Dans un ordre d'idée similaire, le document US 4,712,924 propose une pièce d'horlogerie comprenant deux bras entraînés conventionnellement comme des aiguilles. Ces bras sont reliés par une ligne pour donner une indication horaire. Les documents CH319646 , DE4124775 , EP1491974 , EP1184748 et CH339107 décrivent des affichages de montre comprenant des animations de différentes sortes.In a similar vein, the document US 4,712,924 proposes a timepiece comprising two arms driven conventionally as needles. These arms are connected by a line to give a time indication. The documents CH319646 , DE4124775 , EP1491974 , EP1184748 and CH339107 describe watch displays including animations of different kinds.

La présente invention a pour but de proposer un nouveau type d'animation, particulièrement original. L'invention propose de représenter un objet non-rectiligne, c'est-à-dire de représenter de manière graphique un symbole ou un objet réel dans deux dimensions. Un segment de droite n'est pas considéré comme une représentation d'un tel objet.The present invention aims to propose a new type of animation, particularly original. The invention proposes to represent a non-rectilinear object, that is to say to graphically represent a symbol or a real object in two dimensions. A line segment is not considered a representation of such an object.

Divulgation de l'inventionDisclosure of the invention

De façon plus précise, l'invention concerne une pièce d'horlogerie telle que mentionnée au premier paragraphe de la présente demande, caractérisée en ce que ladite représentation est également formée par au moins un deuxième élément mobile. En outre, le mécanisme d'entraînement est agencé de manière à ce que les éléments mobiles se déplacent chacun et en synchronisme l'un en référence à l'autre, entre une première et une deuxième positions extrêmes. Ces éléments mobiles forment ladite représentation selon une première taille et une deuxième taille plus grande que la première, respectivement lorsqu'ils sont dans leur première et leur deuxième positions extrêmes. La représentation obtenue selon la deuxième taille est une similitude d'un facteur k de la représentation obtenue selon la première taille.More specifically, the invention relates to a timepiece as mentioned in the first paragraph of the present application, characterized in that said representation is also formed by at least one second movable element. In addition, the drive mechanism is arranged so that the movable elements move each in synchronism with each other, between a first and a second extreme positions. These movable elements form said representation in a first size and a second size greater than the first, respectively when they are in their first and second extreme positions. The representation obtained according to the second size is a similarity of a factor k of the representation obtained according to the first size.

Brève description des dessinsBrief description of the drawings

D'autres détails de l'invention apparaîtront plus clairement à la lecture de la description qui suit, faite en référence au dessin annexé dans lequel les figures 1, 2 et 3 proposent des vues chronologiques du fonctionnement d'une pièce d'horlogerie selon un mode préféré de l'invention. La figure 4 propose un autre mode de réalisation de l'invention.Other details of the invention will appear more clearly on reading the description which follows, made with reference to the appended drawing in which the figures 1 , 2 and 3 provide chronological views of the operation of a timepiece according to a preferred embodiment of the invention. The figure 4 proposes another embodiment of the invention.

Mode(s) de réalisation de l'inventionMode (s) of realization of the invention

La description qui va suivre se rapporte à un mode de réalisation préféré, mais qui n'est donné qu'à titre d'exemple non limitatif.The description which follows relates to a preferred embodiment, but which is given by way of non-limiting example.

On peut voir sur les figures une représentation schématique d'une pièce d'horlogerie selon l'invention. Celle-ci comporte un mouvement horloger, non visible au dessin, comprenant une source d'énergie et un système de régulation, pour afficher une information horaire, par exemple au moyen d'aiguilles 10, se déplaçant par-dessus un cadran, qui cache le mouvement.We can see in the figures a schematic representation of a timepiece according to the invention. This includes a watch movement, not visible in the drawing, including a source of energy and a system of regulation, to display a time information, for example by means of needles 10, moving over a dial, which hides the movement.

La pièce d'horlogerie comprend une représentation d'un objet non rectiligne. Dans cet exemple préféré, l'objet est un coeur 12. Ce coeur est formé d'un premier et d'un deuxième éléments mobiles 14a et 14b, reliés cinématiquement à un mécanisme d'entraînement 16 susceptible d'être entraîné par la source d'énergie du mouvement. De préférence, les éléments mobiles 14a et 14b sont distincts et indépendants, c'est-à-dire qu'ils ne sont pas reliés entre eux par un système d'articulation, de type charnière. Comme on le verra ci-après, ils peuvent toutefois être reliés cinématiquement.The timepiece comprises a representation of a non-rectilinear object. In this preferred example, the object is a core 12. This core is formed of a first and a second movable element 14a and 14b, kinematically connected to a drive mechanism 16 that can be driven by the source. energy of the movement. Preferably, the movable elements 14a and 14b are separate and independent, that is to say that they are not interconnected by a hinge type hinge system. As will be seen below, however, they can be kinematically connected.

Selon l'exemple illustré, le mécanisme d'entraînement 16 comprend une came 17, entraînée en rotation par le mouvement. Typiquement, le mécanisme d'entraînement 16 et la représentation sont agencés sur un module indépendant, c'est-à-dire sur un bâti indépendant, monté sur un mouvement de base. La came 17 peut alors être fixée sur un mobile du mouvement de base dont l'axe de pivotement aura été prolongé de manière à s'étendre au niveau du module. De manière avantageuse, on peut également prévoir un train de rouage au niveau du module, de manière à adapter la fréquence des pas de la came 17 et sa vitesse de rotation. La présence éventuelle d'un train de rouage permet également de disposer la came 17 en un endroit choisi par le constructeur, sans être contraint par la position des axes des mobiles du mouvement de base.According to the illustrated example, the drive mechanism 16 comprises a cam 17, driven in rotation by the movement. Typically, the drive mechanism 16 and the representation are arranged on an independent module, that is to say on an independent frame, mounted on a base movement. The cam 17 can then be fixed on a mobile base movement whose pivot axis has been extended so as to extend at the module. Advantageously, it is also possible to provide a gear train at the module, so as to adapt the pitch frequency of the cam 17 and its rotational speed. The possible presence of a gear train also makes it possible to arrange the cam 17 in a place chosen by the manufacturer, without being constrained by the position of the axes of the mobiles of the basic movement.

Dans l'exemple proposé, la came 17 prend la forme d'une roue dentée, munie d'une denture de type asymétrique, à dent de loup ou de scie. Comme on le comprendra ci-après, selon les déplacements que l'on veut obtenir pour les éléments mobiles 14a et 14b, la came 17 peut avoir une autre forme. Notamment, le profil des dents peut être adapté, mais l'homme du métier pourra également envisager des protubérances de toute sorte.In the example proposed, the cam 17 takes the form of a toothed wheel, provided with an asymmetric type tooth, wolf tooth or saw. As will be understood below, depending on the movements that one wants to obtain for the movable elements 14a and 14b, the cam 17 may have another shape. In particular, the profile of the teeth may be adapted, but the skilled person may also consider protuberances of any kind.

Le mécanisme d'entraînement 16 comprend encore deux bascules 18a et 18b, pivotant respectivement autour d'axes A et B. Pour améliorer le pivotement de ces bascules 18a et 18b, tant en matière de guidage que de frottement, elles pourront être montées sur des roulements à billes 19. Chacune des bascules 18a et 18b est montée solidaire d'un des éléments mobiles 14a et 14b. Par exemple, une goupille peut être fixée sur chacune des bascules de manière à relier rigidement la bascule 18a ou 18b et l'élément mobile 14a ou 14b. Les éléments mobiles pourront recevoir un canon et être assemblés sur les bascules à la manière des aiguilles d'une pièce d'horlogerie. Etant donné que tout le mécanisme d'entraînement est destiné à être disposé sous le cadran et que les éléments mobiles 14a et 14b sont destinés à être disposés sur le cadran, les goupilles traversent le cadran au travers de fenêtres ad-hoc ménagées dans celui-ci. Les fenêtres peuvent avantageusement être cachées derrière les éléments mobiles 14a et 14b, quelle que soit leur position.The drive mechanism 16 further comprises two latches 18a and 18b, respectively pivoting about axes A and B. To improve the pivoting of these latches 18a and 18b, both in terms of guiding and friction, they can be mounted on ball bearings 19. Each of the latches 18a and 18b is mounted integral with one of the movable elements 14a and 14b. For example, a pin can be fixed on each of the latches so as to rigidly connect the latch 18a or 18b and the movable member 14a or 14b. The moving elements can receive a barrel and be assembled on the latches in the manner of the needles of a timepiece. Since all the drive mechanism is intended to be arranged under the dial and the movable elements 14a and 14b are intended to be arranged on the dial, the pins pass through the dial through ad-hoc windows formed in the dial. this. The windows can advantageously be hidden behind the movable elements 14a and 14b, whatever their position.

La première bascule 18a comporte un premier palpeur 20a, maintenu appuyé contre la came 17 par un premier ressort 22a. La deuxième bascule 18b comporte un deuxième palpeur 20b qui est maintenu appuyé contre une butée 24a située sur la première bascule 18a, par un deuxième ressort 22b. Ainsi, tandis que la première bascule 18a est entraînée en rotation directement au gré des déplacements de la came 17, la deuxième bascule 18b elle, est entraînée en rotation indirectement, via la première bascule 18a. Ainsi, les déplacements des deux bascules sont parfaitement synchronisés, sans que des différences de réglage au niveau des ressorts 22a et 22b ou au niveau de la coopération entre les palpeurs et la came 17, ne perturbent le synchronisme du déplacement des deux bascules 18a et 18b. On notera que la synchronisation des déplacements des bascules 18a et 18b peut aussi être obtenu avec un appui des deux bascules directement sur la came 17, bien que cela nécessite un réglage fin de la fonction. Pour réduire les frottements, on pourra réaliser les palpeurs en rubis ou les revêtir d'un matériau présentant un faible coefficient de frottement avec le métal de la came ou de la bascule.The first latch 18a comprises a first probe 20a, held pressed against the cam 17 by a first spring 22a. The second flip-flop 18b has a second probe 20b which is held against a stop 24a located on the first flip-flop 18a by a second spring 22b. Thus, while the first latch 18a is rotated directly at the discretion of the movements of the cam 17, the second latch 18b it is driven indirectly indirectly via the first latch 18a. Thus, the movements of the two flip-flops are perfectly synchronized, without differences in the setting of the springs 22a and 22b or at the level of the cooperation between the feelers and the cam 17, disturbing the synchronism of the displacement of the two flip-flops 18a and 18b . Note that the synchronization of the movements of the latches 18a and 18b can also be obtained with a support of the two flip-flops directly on the cam 17, although this requires a fine adjustment of the function. To reduce friction, ruby probes can be made or coated with a material having a low coefficient of friction with the metal of the cam or the rocker.

Les éléments mobiles 14a et 14b se déplacent donc selon des rotations définies en référence aux axes A et B, respectivement, ces axes étant avantageusement distincts. Grâce au fait que les éléments mobiles 14a et 14b sont reliés rigidement aux bascules 18a et 18b, le premier et le deuxième éléments mobiles se déplacent chacun, simultanément et en synchronisme l'un en référence à l'autre, entre une première et une deuxième positions extrêmes et vice-versa, c'est-à-dire selon un déplacement rétrograde. La première position extrême est visible sur la figure 1, tandis que la deuxième position extrême est visible sur la figure 3, la figure 2 montrant une position intermédiaire.The movable elements 14a and 14b therefore move according to rotations defined with reference to the axes A and B, respectively, these axes being advantageously distinct. Due to the fact that the movable elements 14a and 14b are rigidly connected to the latches 18a and 18b, the first and the second second movable elements each move, simultaneously and in synchronism with each other, between a first and a second extreme positions and vice versa, that is to say according to a retrograde movement. The first extreme position is visible on the figure 1 , while the second extreme position is visible on the figure 3 , the figure 2 showing an intermediate position.

Dans la première position extrême, les éléments mobiles 14a et 14b forment la représentation de l'objet non rectiligne, c'est-à-dire le coeur 12, selon une première taille. Dans la deuxième position extrême, les éléments mobiles 14a et 14b forment le coeur 12 selon une deuxième taille, plus grande que la première. La représentation obtenue selon la deuxième taille est une similitude d'un facteur k de la représentation obtenue selon la première taille, k étant déterminé par le design et la construction de la pièce d'horlogerie. Dans les deux tailles respectives de la représentation de l'objet, les dimensions de la représentation varient avantageusement selon au moins deux directions. L'invention ne consiste donc pas à représenter un simple segment de droite plus ou moins grand, un tel segment n'étant en outre pas considéré comme une représentation d'un objet non rectiligne, au sens de la présente invention.In the first extreme position, the movable elements 14a and 14b form the representation of the non-rectilinear object, that is to say the core 12, according to a first size. In the second extreme position, the movable elements 14a and 14b form the core 12 in a second size, larger than the first. The representation obtained according to the second size is a similarity of a factor k of the representation obtained according to the first size, k being determined by the design and construction of the timepiece. In the two respective sizes of the representation of the object, the dimensions of the representation advantageously vary in at least two directions. The invention does not therefore consist in representing a simple segment of a line of greater or lesser size, such a segment being furthermore not considered as a representation of a non-rectilinear object, within the meaning of the present invention.

On pourrait également envisager de synchroniser les déplacements des premier et deuxième éléments mobiles 14a et 14b, en les reliant par engrènement, à la place d'une liaison par l'appui du deuxième palpeur. On pourrait également les relier par une fourchette disposée à l'extrémité de l'un des éléments mobiles, l'autre comportant une cheville coopérant avec la fourchette, les deux éléments étant maintenus en coopération par un petit ressort qui limite également le jeu entre les éléments mobiles. On peut ainsi se passer du deuxième ressort 22b et réduire les chocs entre les éléments mobiles 14a et 14b.One could also consider synchronizing the movements of the first and second movable elements 14a and 14b, connecting them by meshing, instead of a connection by the support of the second probe. They could also be connected by a fork disposed at the end of one of the movable elements, the other having a peg cooperating with the fork, the two elements being held in cooperation by a small spring which also limits the clearance between the moving parts. It is thus possible to dispense with the second spring 22b and reduce shocks between the movable elements 14a and 14b.

De manière particulièrement avantageuse, le mécanisme d'entraînement 16 est agencé, grâce à la forme de la came 17, pour donner l'illusion d'un coeur qui bat. En effet, les bascules 18a et 18b pivotent progressivement tandis que le premier palpeur 20a glisse sur une portion inclinée de la came 17, la première bascule 18a entraînant la deuxième bascule 18b. Puis, les bascules 18a et 18b reviennent brusquement à leur position initiale lorsque le palpeur 20a chute après le passage de la pointe de la dent. En d'autres termes, le coeur 12 passe progressivement de sa première à sa deuxième tailles et revient soudainement à sa première taille.Particularly advantageously, the drive mechanism 16 is arranged, thanks to the shape of the cam 17, to give the illusion of a beating heart. Indeed, the latches 18a and 18b pivot gradually while the first probe 20a slides on an inclined portion of the cam 17, the first flip-flop 18a driving the second flip-flop 18b. Then, the latches 18a and 18b return abruptly to their initial position when the probe 20a falls after the passage of the tip of the tooth. In other words, the heart 12 progressively moves from its first to its second sizes and suddenly returns to its first size.

Pour que l'illusion soit encore meilleure, les éléments du coeur ont une forme particulière. Pour chacun des éléments, chacune des extrémités de l'élément présente une portion concentrique à l'axe de rotation autour duquel la bascule pivote. C'est le cas même pour la partie centrale du coeur.For the illusion to be even better, the elements of the heart have a particular form. For each of the elements, each end of the element has a portion concentric with the axis of rotation around which the rocker pivots. This is the case even for the central part of the heart.

En outre, on peut prévoir que, lorsque le coeur 12 est représenté dans sa première taille, les extrémités des éléments mobiles 14a et 14b sont dimensionnées et conformées de manière à se chevaucher en s'imbriquant. Ceci peut être obtenu soit en adaptant les épaisseurs des extrémités des éléments mobiles, soit en en déformant au moins une de manière à obtenir un recouvrement.In addition, it can be expected that when the core 12 is shown in its first size, the ends of the movable members 14a and 14b are dimensioned and shaped so as to overlap by interlocking. This can be achieved either by adapting the thicknesses of the ends of the movable elements, or by deforming at least one so as to obtain a covering.

De plus, le cadran est muni de portions 26 ayant une apparence similaire en termes de matière et de couleur, à celle des éléments mobiles 14a et 14b. Les portions 26 sont cachées par les éléments mobiles 14a et 14b lorsqu'ils sont dans leur première position extrême. Lorsque ceux-ci passent dans leur deuxième position extrême, les portions 26 sont alors visibles. Grâce à la forme concentrique aux axes A et B, respectivement, des extrémités des éléments mobiles 14a et 14b, les portions 26 peuvent avoir la même dimension, c'est-à-dire la même largeur, que les éléments mobiles 14a et 14b et, lorsqu'ils sont visibles, former avec les éléments mobiles 14a et 14, le coeur 12 dans sa deuxième taille. Dans ce cas, comme on peut le voir sur la figure 3, les portions 26 « prolongent », même si elles sont dans un plan différent, les éléments mobiles 14a et 14b.In addition, the dial is provided with portions 26 having a similar appearance in terms of material and color, that of the movable elements 14a and 14b. The portions 26 are hidden by the movable members 14a and 14b when in their first extreme position. When they pass in their second extreme position, the portions 26 are then visible. Thanks to the shape concentric to the axes A and B, respectively, of the ends of the movable elements 14a and 14b, the portions 26 may have the same dimension, that is to say the same width, as the movable elements 14a and 14b and when they are visible, form with the movable elements 14a and 14, the core 12 in its second size. In this case, as can be seen on the figure 3 , the portions 26 "extend", even if they are in a different plane, the movable elements 14a and 14b.

Dans un mode de réalisation préféré, la combinaison de la forme spécifique du coeur 12, d'une forme adaptée de la came 17, d'un rythme d'entraînement convenable, permettent de donner l'illusion d'un battement de coeur, tel qu'on le représente parfois de manière stylisée.In a preferred embodiment, the combination of the specific shape of the heart 12, a suitable shape of the cam 17, a suitable driving rhythm, allow to give the illusion of a heartbeat, such as it is sometimes represented in a stylized way.

Dans l'invention qui vient d'être décrite, la représentation choisie est celle d'un coeur, mais d'autres objets non rectilignes pourraient également être choisis. On pourrait ainsi représenter une étoile, une bouche, ou diverses formes qui pourraient être représentées par un nombre relativement limité d'éléments mobiles. On peut en effet envisager d'utiliser jusqu'à quatre, voir six éléments mobiles. Par ailleurs, les éléments mobiles peuvent être combinés à des éléments statiques, visibles en permanence, pour représenter l'objet choisi. On notera que, de préférence, les éléments mobiles sont destinés à se déplacer en rotation autour d'axes respectifs distincts, au moins autour d'une pluralité d'axes.In the invention which has just been described, the representation chosen is that of a heart, but other non-rectilinear objects could also be chosen. One could thus represent a star, a mouth, or various forms that could be represented by a relatively limited number of moving elements. One can indeed consider using up to four, see six moving elements. Furthermore, the movable elements can be combined with static elements, permanently visible, to represent the chosen object. It should be noted that, preferably, the movable elements are intended to move in rotation about respective distinct axes, at least around a plurality of axes.

Le mécanisme décrit ci-dessus est compatible avec un système de régulation mécanique ou à quartz. Un mécanisme d'entraînement 16 tel que proposé ci-dessus peut être adapté dans une réalisation électromécanique. On pourrait également prévoir, le cas échéant, un mécanisme d'entraînement indépendant pour chacun des éléments mobiles, les systèmes d'entraînement étant synchronisés par un circuit électronique contrôlé.The mechanism described above is compatible with a mechanical or quartz control system. A drive mechanism 16 as proposed above can be adapted in an electromechanical embodiment. One could also provide, if necessary, an independent drive mechanism for each of the movable elements, the drive systems being synchronized by a controlled electronic circuit.

L'homme du métier pourrait également prévoir un système de commande, pour enclencher ou arrêter le mécanisme d'entraînement 16 et les mouvements de la représentation. Dans une pièce d'horlogerie mécanique ou électromécanique, le système de commande peut agir sur un mécanisme d'embrayage, tel que ceux utilisés dans les mécanismes de chronographe, intercalé dans la chaîne cinématique reliant le mouvement à la came 17. Le débrayage du système d'embrayage stoppe la rotation de la came 17. Dans une pièce d'horlogerie électronique, le système de commande peut agir directement sur le circuit électronique de commande.Those skilled in the art could also provide a control system, to engage or stop the drive mechanism 16 and the movements of the representation. In a mechanical or electromechanical timepiece, the control system can act on a clutch mechanism, such as those used in the chronograph mechanisms, inserted in the kinematic chain connecting the movement to the cam 17. The disengagement of the system clutch stops the rotation of the cam 17. In an electronic timepiece, the control system can act directly on the electronic control circuit.

Le système de commande peut être un système de commande manuel, tel qu'un poussoir. Mais on peut également prévoir un système de commande automatique, tel que proposé dans des alarmes ou des réveils. A une heure programmée, le système de commande enclenche alors automatiquement le mécanisme d'entraînement 16 et le coeur ou la représentation choisie se meut d'une taille à l'autre. Dans une telle réalisation de type mécanique, on pourra alors prévoir que le mécanisme d'entraînement soit associé à sa propre source d'énergie, éventuellement située dans le module. Toutefois, en s'inspirant d'une grande sonnerie, on peut également envisager de prélever l'énergie pour l'entraînement de la représentation, dans le barillet du mouvement. L'arrêt de l'entraînement se produit soit après un temps déterminé, soit lorsque le barillet spécifique est déchargé. L'homme du métier saura utiliser ses connaissances générales en matière de mécanismes de sonnerie pour mettre en oeuvre cette variante de l'invention. Pour une telle réalisation de type électronique ou électromécanique, le circuit électronique peut être programmé de manière à réagir à un actionnement d'un organe de commande manuel ou pour définir la durée et le moment auquel la représentation est mue.The control system may be a manual control system, such as a pusher. But we can also provide an automatic control system, as proposed in alarms or alarm clocks. At a programmed time, the control system then automatically engages the drive mechanism 16 and the heart or the chosen representation moves from one size to another. In such an embodiment of the mechanical type, can then provide that the drive mechanism is associated with its own power source, possibly located in the module. However, inspired by a great ring, we can also consider taking the energy for the training of the representation in the barrel of the movement. The stopping of the training occurs either after a certain time or when the specific barrel is unloaded. Those skilled in the art will know how to use their general knowledge of striking mechanisms to implement this variant of the invention. For such an embodiment of electronic or electromechanical type, the electronic circuit can be programmed to react to an actuation of a manual control member or to define the duration and the moment at which the representation is moved.

On pourra éventuellement prévoir que les éléments mobiles soient directement entraînés par les déplacements d'une masse oscillante, du type de celles utilisées dans les mécanismes de remontage automatique, la masse oscillante étant solidaire en rotation ou liée cinématiquement à la came, pour entraîner les éléments mobiles au gré des mouvements du porteur de la pièce d'horlogerie.It may be possible to provide that the moving elements are directly driven by the movements of an oscillating mass, of the type used in the automatic winding mechanisms, the oscillating mass being integral in rotation or kinematically connected to the cam, to drive the elements. moving according to the movements of the wearer of the timepiece.

Une pièce d'horlogerie selon l'invention trouve à s'appliquer dans une montre bracelet. Elle peut également trouver à s'appliquer dans un objet de parure quelconque, de type bijou (fig. 4), tel qu'un collier ou autre pendentif, ou encore tel qu'une broche. Bien que dans cette application, le mécanisme puisse ne pas donner l'heure et être dépourvu, notamment, de moyens d'affichage d'une information horaire, il peut néanmoins être légitimement compris dans la portée des termes « pièce d'horlogerie » utilisés dans les revendications, étant donné qu'il reprend des systèmes utilisés dans l'horlogerie.A timepiece according to the invention is applicable in a wristwatch. It can also find application in an object of adornment of some kind, jewel ( Fig. 4 ), such as a necklace or other pendant, or like a brooch. Although in this application, the mechanism may not give the time and be lacking, in particular, means of displaying a time information, it may nevertheless be legitimately included in the scope of the terms "timepiece" used in the claims, since it includes systems used in the watch industry.
