Description

La présente invention concerne un organe régulateur, notamment un organe régulateur destiné à être intégré dans une montre mécanique, comportant un premier balancier et un premier spiral, ainsi qu'un mouvement de montre mécanique voire une pièce d'horlogerie comportant un tel organe régulateur.The present invention relates to a regulating member, in particular a regulating member intended to be integrated in a mechanical watch, comprising a first balance wheel and a first balance spring, as well as a mechanical watch movement or even a timepiece comprising such a regulating member.

L'organe régulateur d'une pièce d'horlogerie mécanique est normalement composé d'un balancier et d'un spiral et forme la partie oscillante du mouvement de la pièce d'horlogerie. D'une part, déterminant par sa période d'oscillation la précision de la pièce d'horlogerie mécanique et, d'autre part, étant perçu comme le coeur vivant d'un objet inanimé du fait de son « battement », cette partie centrale que constitue l'organe régulateur a depuis l'invention des montres mécaniques constamment été l'objet d'améliorations et de développements.The regulating member of a mechanical timepiece is normally composed of a balance and a spiral and forms the oscillating part of the movement of the timepiece. On the one hand, determining by its period of oscillation the precision of the mechanical timepiece and, on the other hand, being perceived as the living heart of an inanimate object because of its "beat", this central part What constitutes the regulating organ has since the invention of mechanical watches constantly been the subject of improvements and developments.

Par exemple, dans le souci d'améliorer la précision des montres mécaniques, c'est-à-dire d'améliorer la précision de la période d'oscillation de l'organe régulateur, il a été proposé par le passé d'intégrer dans l'organe régulateur un deuxième spiral, ceci selon plusieurs variantes en modifiant notamment la position du deuxième spiral. Dans le même contexte s'inscrivent également les dispositifs réalisés par le passé dans lesquels l'organe régulateur est composé de deux voir plusieurs balanciers spiraux agencés sur des axes parallèles. Ces derniers dispositifs sont relativement complexes et volumineux, par conséquent assez difficiles et coûteux à produire.For example, in order to improve the accuracy of mechanical watches, that is to say to improve the accuracy of the oscillation period of the regulating organ, it has been proposed in the past to integrate in the regulating member a second hairspring, this according to several variants by modifying in particular the position of the second hairspring. In the same context also include devices made in the past in which the regulating member is composed of two or more spiral balances arranged on parallel axes. These devices are relatively complex and bulky, therefore quite difficult and expensive to produce.

A part les développements techniques mentionnés ci-dessus ainsi que d'autres efforts non mentionnés dans cette description pour des raisons de volume et qui ciblent principalement la précision de marche de la pièce d'horlogerie mécanique correspondante, d'autres développements techniques ont été réalisés qui visent notamment à augmenter l'attractivité esthétique des montres correspondantes. En particulier, l'organe régulateur est utilisé depuis déjà un bon nombre d'années de manière à augmenter l'esthétique des montres mécaniques, par exemple en équipant les boîtes de montres d'un fond transparent en saphir de façon à ce que l'on puisse observer le mouvement de la montre, notamment les battements de l'organe régulateur de la montre. Cette solution présente un désavantage, à savoir que, pour pouvoir observer toute l'élégance de cette partie du mouvement, il est nécessaire d'ôter la montre du poignet du porteur et de la retourner, sauf dans les montres squelettes ou tourbillon qui ont une ouverture dans le cadran et dans lesquelles l'observation de l'organe régulateur se fait normalement par ce côté de la montre.Apart from the technical developments mentioned above as well as other efforts not mentioned in this description for reasons of volume and which mainly target the running accuracy of the timepiece corresponding mechanical, other technical developments have been made which aim in particular to increase the aesthetic attractiveness of the corresponding watches. In particular, the regulating member has been used for a number of years already in order to increase the aesthetics of mechanical watches, for example by equipping the watch cases with a transparent sapphire back so that the we can observe the movement of the watch, including the beats of the regulating organ of the watch. This solution has the disadvantage that, in order to be able to observe all the elegance of this part of the movement, it is necessary to remove the watch from the wearer's wrist and turn it over, except in skeleton or tourbillon watches which have a opening in the dial and in which the observation of the regulating organ is normally done by this side of the watch.

Considérant alors les dispositifs de l'art antérieur passé brièvement en revue ci-dessus, il est à constater qu'il serait souhaitable de disposer d'un organe régulateur pour pièces d'horlogerie mécanique qui réponde encore mieux aux exigences actuelles en ce qui concerne sa précision de marche ainsi que son aptitude à être utilisé de manière à mettre en valeur visuellement le mouvement et notamment le balancier.Considering then the devices of the prior art briefly reviewed above, it should be noted that it would be desirable to have a regulating organ for mechanical timepieces which still better meets the current requirements with regard to its accuracy and its ability to be used to visually enhance the movement and especially the pendulum.

Le but de la présente invention est donc de remédier aux inconvénients des organes régulateurs connus actuellement et de réaliser les avantages susmentionnés, notamment de permettre la réalisation d'un organe régulateur pour pièces d'horlogerie mécanique dont la précision de marche est améliorée sans pour autant trop augmenter la complexité, le volume occupé, voire le coût de production, et qui est adapté à être mis en valeur visuellement dans la montre mécanique correspondante, ceci autant quand la montre est portée, c'est-à-dire à-travers la glace de la montre, que quand la montre est enlevée du poignet et retournée, c'est-à-dire à travers un fond en saphir de la boîte de montre.The object of the present invention is therefore to overcome the drawbacks of the currently known regulating members and to achieve the above-mentioned advantages, in particular to enable the production of a regulating organ for mechanical timepieces whose accuracy of operation is improved without however To increase the complexity, the volume occupied or the cost of production, and which is adapted to be highlighted visually in the corresponding mechanical watch, this as much when the watch is worn, that is to say through the ice of the watch, only when the watch is removed from the wrist and returned, ie through a sapphire caseback caseback.

A cet effet, la présente invention propose un organe régulateur, notamment un organe régulateur d'une montre mécanique, qui se distingue par les caractéristiques énoncées à la revendication 1, voire un mouvement de montre respectivement une pièce d'horlogerie correspondants. En particulier, un organe régulateur selon la présente invention comprend au moins un deuxième balancier fixé sur l'axe dudit premier balancier. De préférence, il comprend également au moins un deuxième spiral arrangé sur ledit au moins deuxième balancier.For this purpose, the present invention provides a regulating member, in particular a regulating member of a mechanical watch, which is distinguished by the features set forth in claim 1, or a watch movement respectively a corresponding timepiece. In particular, a regulating member according to the present invention comprises at least one second rocker fixed on the axis of said first rocker. Preferably, it also comprises at least one second hairspring arranged on said at least one second beam.

Par ces mesures, on obtient un organe régulateur pour des pièces d'horlogerie mécanique qui offre une précision de marche très élevée du fait de sa grande inertie obtenue sans augmentation du diamètre du dispositif et, le cas échéant, du fait d'être équipé de deux ressorts spiraux. Par rapport au dispositif de l'art antérieur utilisant deux spiraux, l'organe régulateur selon la présente invention a aussi l'avantage de faciliter la mise en marche des deux spiraux, car la présence d'un deuxième balancier sur le même axe enlève majoritairement la difficulté de vision pour distinguer entre les deux spiraux qui se posait pour le régleur de la montre dans les dispositifs de l'art antérieur. De plus, l'organe régulateur selon la présente invention, en étant équipé de deux balanciers sur un axe, est évidement idéalement adapté à être mis en valeur visuellement à-travers des fenêtres transparentes se trouvant des deux côtés d'une montre mécanique.By these measurements, a regulating organ for mechanical timepieces is obtained which offers a very high running accuracy because of its great inertia obtained without increasing the diameter of the device and, if necessary, being equipped with two spiral springs. Compared to the device of the prior art using two spirals, the regulating member according to the present invention also has the advantage of facilitating the start of the two spirals, because the presence of a second beam on the same axis removes the majority. the difficulty of vision to distinguish between the two spirals which arose for the adjuster of the watch in the devices of the prior art. In addition, the regulator member according to the present invention, being equipped with two rockers on one axis, is obviously ideally suited to be highlighted visually through the transparent windows on both sides of a mechanical watch.

D'autres caractéristiques, ainsi que les avantages correspondants, ressortiront des revendications dépendantes, ainsi que de la description exposant ci après l'invention plus en détail.Other features, as well as the corresponding advantages, will emerge from the dependent claims, as well as from the description which follows, in more detail.

L'invention va maintenant être décrite en détail en référence aux dessins annexés illustrant à titre d'exemple une forme d'exécution de l'invention.The invention will now be described in detail with reference to the accompanying drawings illustrating by way of example an embodiment of the invention.

Un organe régulateur selon la présente invention est destiné à être intégré dans un mouvement d'une pièce d'horlogerie mécanique, notamment dans une montre mécanique dont la boîte de montre permet d'apercevoir le mouvement de la montre et en particulier l'oscillation du balancier de l'organe régulateur, ceci de préférence des deux côtés de la montre. Comme cela ressort de la figure 1, un tel organe régulateur 1 comprend un premier balancier 2.1 et un premier spiral 3.1, ce balancier 2.1 et le spiral 3.1 étant montés proches d'une première extrémité 4.1 de l'axe 4 du balancier. L'organe régulateur selon la présente invention se distingue des dispositifs de l'art antérieur du fait qu'il comprend au moins un deuxième balancier 2.2 fixé sur le même axe 4 que le premier balancier 2.1 et de manière rigide par rapport à ce dernier. De préférence, le deuxième balancier 2.2 est monté proche de l'autre extrémité 4.2 de l'axe 4, tel que cela est illustré schématiquement à la coupe verticale de la figure 2.A regulating member according to the present invention is intended to be integrated into a movement of a mechanical timepiece, in particular in a mechanical watch whose watch case makes it possible to see the movement of the watch and in particular the oscillation of the watch. balance of the regulating organ, this preferably on both sides of the watch. As is apparent from the figure 1 such a regulating member 1 comprises a first rocker 2.1 and a first hairspring 3.1, this rocker 2.1 and the hairspring 3.1 being mounted close to a first end 4.1 of the axis 4 of the beam. The regulating member according to the present invention differs from the devices of the prior art in that it comprises at least one second rocker 2.2 fixed on the same axis 4 as the first rocker 2.1 and rigidly relative thereto. Preferably, the second rocker 2.2 is mounted close to the other end 4.2 of the axis 4, as shown schematically in the vertical section of the figure 2 .

Il ressort également des figures 1 et 2 que l'organe régulateur 1 selon la présente invention comprend de manière avantageuse également au moins un deuxième spiral 3.2 qui est arrangé sur le deuxième balancier 2.2. Dans une forme d'exécution préférée de la présente invention et tel qu'illustré notamment à la figure 2, ledit premier spiral 3.1 ainsi que ledit deuxième spiral 3.2 sont chacun arrangés sur le côté orienté vers l'extérieur dudit premier balancier 2.1 respectivement dudit deuxième balancier 2.2. Cette disposition est également illustrée aux figures 3a et 3b qui montrent respectivement une vue de dessus de l'organe régulateur selon la présente invention et une vue de dessus de la partie inférieure de l'organe régulateur le long de la ligne IIIb-IIIb indiquée dans la figure 2.It is also apparent Figures 1 and 2 that the regulating member 1 according to the present invention advantageously also comprises at least one second balance spring 3.2 which is arranged on the second balance beam 2.2. In a preferred embodiment of the present invention and as illustrated in particular in the figure 2 , said first hairspring 3.1 and said second hairspring 3.2 are each arranged on the outwardly facing side of said first rocker 2.1 respectively said second rocker 2.2. This provision is also illustrated in Figures 3a and 3b which respectively show a view from above of the regulator member according to the present invention and a view from above of the lower part of the regulator member along the line IIIb-IIIb indicated in FIG. figure 2 .

Un organe régulateur comportant les caractéristiques mentionnées ci-dessus selon la présente invention présente ainsi les avantages suivants.A regulating member having the characteristics mentioned above according to the present invention thus has the following advantages.

D'une part, la précision de marche d'un mouvement mécanique intégrant un tel organe régulateur est améliorée du fait que l'inertie du balancier a été approximativement doublée sans pour autant augmenter le diamètre du dispositif. De même, la précision de la période d'oscillation du balancier peut sensiblement être améliorée en cas d'utilisation de deux spiraux, notamment en cas d'utilisation des spiraux plats. Ces derniers pourraient être remplacés par des spiraux de type Breguet ou tout autre type de spiraux connus par l'homme du métier, mais il est préférable d'utiliser, dans la forme d'exécution préférée de l'organe régulateur selon la présente invention, deux voire en général un nombre pair de spiraux plats simples, ceci du fait que ceux-ci permettent d'obtenir quasiment le même résultat de performance en termes de précision de marche du mouvement que l'utilisation de spiraux de type Breguet, voire un meilleur résultat si la courbe Breguet du spiral n'est pas parfaitement maîtrisée. L'organe régulateur selon la présente invention utilisant deux balanciers et deux spiraux permet alors d'optimiser la précision de l'oscillation du balancier sans pour autant nécessiter une complexité ou un volume trop élevé du dispositif, ce qui permet de réaliser la présente invention à des coûts de production relativement modérés.On the one hand, the accuracy of a mechanical movement incorporating such a regulating member is improved because the inertia of the balance has been approximately doubled without increasing the diameter of the device. Similarly, the accuracy of the pendulum swing period can be substantially improved when using two spirals, especially when using flat spirals. These could be replaced by spirals Breguet type or any other type of spiral known to those skilled in the art, but it is preferable to use, in the preferred embodiment of the regulating member according to the present invention, two or even in general an even number of simple flat spirals, this because they allow to obtain almost the same performance result in terms of accuracy of movement of the movement as the use of spirals Breguet type or a better result if the Breguet curve of the spiral is not perfectly controlled. The regulating member according to the present invention using two rockers and two spirals then makes it possible to optimize the accuracy of the pendulum oscillation without requiring a complexity or too high volume of the device, which allows the realization of the present invention at relatively low production costs.

D'autre part, grâce notamment à la présence de deux balanciers 2.1, 2.2 montés sur les extrémités respectives de l'axe 4 du dispositif, un tel organe régulateur est idéalement adapté à mettre en valeur techniquement et esthétiquement le mouvement d'une montre mécanique. En effet, la montre mécanique peut-être équipée d'une boîte de montre comportant, sur ses deux côtés, c'est-à-dire côté cadran ainsi que côté fond de la montre, des fenêtres transparentes à travers lesquelles le mouvement mécanique et en particulier l'oscillation du balancier peut-être observé. L'organe régulateur selon la présente invention disposant de deux balanciers aux extrémités 4.1, 4.2 respectives de l'axe 4, l'oscillation d'au moins un des balanciers 2.1, 2.2 battant en synchrone peut alors être observée de manière optimale à travers une des fenêtres correspondantes côté cadran ou côté fond de la boîte de montre, sans pour autant que le balancier que l'observateur a décidé d'admirer soit caché par d'autres pièces du mouvement mécanique.On the other hand, thanks in particular to the presence of two rockers 2.1, 2.2 mounted on the respective ends of the axis 4 of the device, such a regulating member is ideally suited to enhance technically and aesthetically the movement of a mechanical watch . Indeed, the mechanical watch may be equipped with a watch case having, on its two sides, that is to say on the dial side and the bottom side of the watch, transparent windows through which the mechanical movement and in particular the oscillation of the pendulum can be observed. Since the regulating member according to the present invention has two rockers at the respective ends 4.1, 4.2 of the axis 4, the oscillation of at least one of the synchronously oscillating gimbals 2.1, 2.2 can then be observed optimally through a corresponding windows on the dial or bottom side of the watch case, without the pendulum that the observer has decided to admire is hidden by other parts of the mechanical movement.

De plus, en cas d'utilisation de deux spiraux correspondant aux deux balanciers et agencés respectivement sur ces derniers, les opérations de contrôle ou de réglages lors de la production voire du service client sont grandement facilités pour un organe régulateur selon la présente invention par rapport aux dispositifs de l'art antérieur. En effet, dans les dispositifs connus utilisant deux spiraux, ces derniers étaient souvent superposés l'un au-dessus de l'autre, ce qui engendre une difficulté de vision ne permettant, pour le régleur de la montre, que très difficilement de distinguer entre les deux spiraux et ainsi de réaliser leur mise en marche que dans des conditions assez désavantageuses. A l'encontre, la présente invention propose, grâce à l'utilisation de deux balanciers 2.1, 2.2, de séparer par une distance axiale relativement importante les deux spiraux 3.1, 3.2, ce qui permet au régleur de la montre de décemment réaliser les opérations de contrôle ou de réglage voire la mise en marche, ceci de manière quasiment traditionnelle du fait que les deux spiraux peuvent ainsi être considérés comme étant indépendants, le premier spiral 3.1 ne perturbant pas par superposition la mise en marche du deuxième spiral 3.2.In addition, when using two spirals corresponding to the two balances and arranged respectively on the latter, the control operations or adjustments during production or customer service are greatly facilitated for a regulating member according to the present invention compared to to the devices of the prior art. Indeed, in known devices using two spirals, the latter were often superimposed one above the other, which causes a difficulty of vision not allowing, for the adjuster of the watch, very difficult to distinguish between the two spirals and so realize their start that under rather unfavorable conditions. In contrast, the present invention proposes, thanks to the use of two rockers 2.1, 2.2, of to separate by a relatively large axial distance the two spirals 3.1, 3.2, which allows the adjuster of the watch to decently carry out control or adjustment operations or even start-up, this in an almost traditional manner because the two spirals can thus be considered as independent, the first hairspring 3.1 not disturbing by superposition the start of the second hairspring 3.2.

Il reste à constater qu'un organe régulateur 1 selon la présente invention pourrait également, dans une constellation non illustrée aux figures, comprendre plus de deux balanciers fixés sur le même axe 4, par exemple un troisième balancier fixé sur l'axe 4 desdits premier balancier 2.1 et deuxième balancier 2.2 et arrangé entre ces derniers. Par ailleurs, un tel organe régulateur 1 comprend également, de manière générale, un nombre pair de spiraux montés chacun sur un balancier correspondant, par exemple un spiral fixé sur le premier respectivement deuxième balancier et deux spiraux montés de chaque côté dudit troisième balancier, ou quatre balanciers avec chacun un spiral correspondant. Les balanciers, qu'il y en ait deux ou plusieurs, peuvent aussi avoir un diamètre, une hauteur, et/ou une forme différents, ceci dans la limite de l'espace disponible voire d'autres contraintes techniques et selon l'esthétique souhaitée. Il est encore à noter que le spiral voire les spiraux de l'organe régulateur selon la présente invention sont montés de manière conventionnelle au balancier et aux ponts de balancier correspondants par l'intermédiaire d'une virole et d'un piton.It remains to be noted that a regulating member 1 according to the present invention could also, in a constellation not illustrated in the figures, comprise more than two rockers fixed on the same axis 4, for example a third rocker fixed on the axis 4 of said first balance 2.1 and second balance 2.2 and arranged between them. Moreover, such a regulating member 1 also comprises, in general, an even number of spirals each mounted on a corresponding balance, for example a spiral fixed on the first respectively second balance and two spirals mounted on each side of said third balance, or four pendulums each with a corresponding hairspring. The pendulums, whether there are two or more, may also have a different diameter, height, and / or shape, this within the limits of available space or even other technical constraints and according to the desired aesthetic . It should also be noted that the spiral or spirals of the regulating member according to the present invention are conventionally mounted to the balance and the corresponding balance bridges via a ferrule and a stud.

Un organe régulateur selon la présente invention peut coopérer de manière conventionnelle avec les autres parties du mouvement mécanique de la montre, à savoir avec le moteur, le rouage et l'échappement du mouvement. De préférence, l'échappement d'un mouvement de montre incorporant un organe régulateur 1 selon la présente invention est arrangé au moins partiellement entre lesdits premier balancier 2.1 et deuxième balancier 2.2 de l'organe régulateur 1. Ainsi, un mouvement de montre équipé d'un tel organe régulateur voire une pièce d'horlogerie équipée d'un tel mouvement mécanique forment également l'objet de la présente invention, notamment en cas d'une telle disposition spécifique de l'échappement.A regulating member according to the present invention can cooperate in a conventional manner with the other parts of the mechanical movement of the watch, namely with the motor, the wheel and the escapement of the movement. Preferably, the escapement of a watch movement incorporating a regulating member 1 according to the present invention is arranged at least partially between said first rocker 2.1 and second rocker arm 2.2 of the regulating member 1. Thus, a watch movement equipped with such a regulating member or even a timepiece equipped with such a mechanical movement also form the subject of the present invention, particularly in the case of such a specific provision of the exhaust.

Au vu de la description détaillée figurant ci-dessus, il est clair que la présente invention propose un organe régulateur pour une pièce d'horlogerie mécanique dont la précision de marche se trouve améliorée sans trop augmenter la complexité technique ou les coûts de production et qui est idéalement adapté à être mis en valeur visuellement à travers des fenêtres se trouvant des deux côtés de la boîte de montre, contribuant ainsi de manière importante à l'esthétique de la pièce d'horlogerie.In view of the detailed description above, it is clear that the present invention proposes a regulating member for a mechanical timepiece whose operating accuracy is improved without increasing too much the technical complexity or the production costs and which is ideally suited to be highlighted visually through windows on both sides of the watch case, thus contributing significantly to the aesthetics of the timepiece.
