Description

Mouvement horloger à régulateur à résonance tridimensionnelle magnétique Introduction  Watch movement with magnetic three-dimensional resonance controller Introduction
La présente invention concerne un régulateur oscillant pour pièce d'horlogerie, et un assemblage horloger intégrant un tel régulateur. Elle concerne donc aussi un mouvement d'horlogerie et une pièce d'horlogerie en tant que tels intégrant un tel régulateur, et particulièrement une montre, comme une montre bracelet, en tant que telle intégrant un tel régulateur. The present invention relates to an oscillating regulator for a timepiece, and a watch assembly incorporating such a regulator. It therefore also concerns a watch movement and a timepiece as such incorporating such a regulator, and particularly a watch, such as a wristwatch, as such incorporating such a regulator.
Etat de l'Art La précision d'une montre mécanique conventionnelle repose en grande partie sur le fonctionnement de son régulateur. Ce dernier se présente généralement sous la forme d'un système oscillant, comprenant la plupart du temps un ensemble balancier-spiral ou un pendule. Ce système oscillant présente une fréquence de fonctionnement propre et stable, qui est exploitée pour imposer une mesure de temps maîtrisée à la montre. Il est lié à un accumulateur d'énergie, comme un barillet, qui dispense une énergie à un échappement par un rouage. L'échappement transmet ensuite de manière périodique des pulsations au système oscillant pour entretenir ses oscillations de manière durable. Le système de distribution d'énergie au système oscillant est conçu pour entretenir les mouvements d'oscillation sans les perturber. STATE OF THE ART The accuracy of a conventional mechanical watch rests largely on the operation of its regulator. The latter is generally in the form of an oscillating system, most often comprising a pendulum-balance or a pendulum. This oscillating system has a clean and stable operating frequency, which is exploited to impose a measure of time controlled watch. It is linked to an energy accumulator, like a cylinder, which dispenses energy to an escapement by a cog. The escapement then periodically transmits pulses to the oscillating system to sustain its oscillations in a sustainable manner. The oscillating system power distribution system is designed to maintain oscillation movements without disturbing them.
Le fonctionnement d'un tel régulateur de l'état de la technique reste toutefois imparfait, du fait des imperfections intrinsèques du système oscillant et/ou du système de distribution d'énergie qui lui est associé, qui vont décaler son fonctionnement d'un fonctionnement idéal et théorique. De plus, le régulateur est aussi soumis à l'influence de la force de gravitation qui peut varier si l'orientation du régulateur change, ce qui est le cas dans une montre bracelet. Ces différents phénomènes conduisent à une perte de précision de la mesure du temps d'une pièce d'horlogerie. The operation of such a regulator of the state of the art remains imperfect, however, because of intrinsic imperfections of the oscillating system and / or the energy distribution system associated therewith, which will shift its operation of an operation. ideal and theoretical. In addition, The regulator is also subject to the influence of the gravitational force which can vary if the orientation of the regulator changes, which is the case in a wristwatch. These different phenomena lead to a loss of precision of the time measurement of a timepiece.
Pour pallier certains de ces inconvénients, certaines solutions reposent sur des systèmes mécaniques complexes. S'agissant par exemple de réduire l'influence de la gravitation, il existe en particulier des solutions à base de tourbillon, dont le principe est la mise en mouvement du régulateur autour d'un ou plusieurs axes de rotation pour rendre finalement son fonctionnement global moins dépendant de son orientation. Ces solutions complexes sont très coûteuses et l'amélioration de la précision du régulateur à base de système oscillant n'est atteinte qu'au prix d'une mise au point d'un système mécanique complexe, ce qui n'est pas aisé. To overcome some of these disadvantages, some solutions rely on complex mechanical systems. For example, to reduce the influence of gravitation, there are in particular vortex-based solutions, whose principle is the setting in motion of the regulator around one or more axes of rotation to finally make its overall operation less dependent on its orientation. These complex solutions are very expensive and the improvement of the accuracy of the oscillating system-based regulator is only achieved at the cost of a development of a complex mechanical system, which is not easy.
D'autres solutions pour améliorer la précision de la mesure du temps par un régulateur à base de système oscillant ont été proposées, comme celle décrite à titre d'exemple par le document EP1 640821 . Ce document décrit un mouvement d'horlogerie utilisant une pluralité de balanciers fonctionnant en résonance. Ce principe permet théoriquement de s'affranchir des défauts d'un seul balancier et d'obtenir une mesure de temps globalement améliorée, puisque les éventuels différents défauts de chaque balancier sont censés être compensés par les autres balanciers qui ne présenteront probablement pas les mêmes défauts au même instant. Le régulateur global formé par la réunion des balanciers en résonance présenterait ainsi un fonctionnement en moyenne plus précis et fiable que celui de chaque balancier indépendant le constituant. Cette solution est basée sur une approche théorique. Toutefois, sa mise en pratique pose des problèmes techniques qui n'ont pas été surmontés. En effet, pour obtenir le fonctionnement stable en résonance de différents balanciers, il faut que ces balanciers soient dotés des mêmes propriétés oscillatoires, soient de préférence identiques en poids, géométrie, réglage de fonctionnement, et subissent à tout instant exactement les mêmes influences extérieures. Ces conditions étant rarement atteintes, le principe de la résonance n'a ainsi pas pu apporter les résultats espérés pour la mesure du temps dans l'état de la technique. Other solutions for improving the accuracy of time measurement by an oscillating system-based regulator have been proposed, such as that described by way of example in EP1 640821. This document describes a clockwork movement using a plurality of resonance-operated pendulums. This principle theoretically makes it possible to overcome the defects of a single pendulum and to obtain a time measurement that is globally improved, since the possible different defects of each pendulum are supposed to be offset by the other pendulums which will probably not have the same defects. at the same time. The global regulator formed by the meeting resonance balances and present an operation on average more accurate and reliable than that of each independent balance constituting it. This solution is based on a theoretical approach. However, putting it into practice poses technical problems that have not been overcome. Indeed, to obtain the stable operation in resonance of different rockers, it is necessary that these rockers are equipped with the same oscillatory properties, either preferably identical in weight, geometry, adjustment of operation, and undergo at all times exactly the same external influences. Since these conditions are rarely achieved, the principle of resonance has not been able to provide the expected results for the measurement of time in the state of the art.
Le document WO2014180767 propose ainsi une solution simplifiée et plus performante, reposant sur plusieurs balanciers fonctionnant en résonance. Il reste toutefois toujours complexe en pratique d'atteindre une résonance entre des balanciers et d'atteindre les avantages théoriques qu'une telle solution pourrait apporter. Document WO2014180767 thus proposes a simplified and more efficient solution, based on several resonance-operated balances. However, it remains difficult in practice to reach a resonance between rockers and achieve the theoretical benefits that such a solution could provide.
Ainsi, l'invention a pour objet général de proposer une solution de mesure du temps pour une pièce d'horlogerie qui ne comprend pas tout ou partie des inconvénients des solutions de l'état de la technique. Thus, the general object of the invention is to propose a solution for measuring time for a timepiece that does not include all or part of the disadvantages of the solutions of the state of the art.
Plus précisément, un premier objet de l'invention est de proposer une solution de mesure du temps permettant d'atteindre une grande précision, notamment pour une utilisation au sein d'une montre-bracelet, notamment permettant de fortement réduire, voire annuler, l'effet néfaste de la pesanteur sur l'isochronisme de la montre. More specifically, a first object of the invention is to provide a solution for measuring time to achieve high accuracy, especially for use within a wristwatch, in particular to greatly reduce or even cancel the the detrimental effect of gravity on the isochronism of the watch.
Un second objet de l'invention est de proposer une solution de mesure du temps peu encombrante, compatible avec une utilisation au sein d'une montre, notamment une montre-bracelet. A second object of the invention is to provide a solution for measuring space-saving time, compatible with use within a watch, in particular a wristwatch.

Ces objets, caractéristiques et avantages de la présente invention seront exposés en détail dans la description suivante d'un mode de réalisation particulier fait à titre non-limitatif en relation avec les figures jointes parmi lesquelles : La figure 1 représente une vue en perspective simplifiée d'un régulateur oscillant selon un mode de réalisation de l'invention. These objects, features and advantages of the present invention will be set forth in detail in the following description of a particular embodiment made in a non-limiting manner in relation to the appended figures among which: FIG. 1 represents a simplified perspective view of an oscillating regulator according to one embodiment of the invention.
La figure 2 représente une vue de dessous du régulateur oscillant selon le mode de réalisation de l'invention. FIG. 2 represents a view from below of the oscillating regulator according to the embodiment of the invention.
La figure 3 représente une vue de côté du régulateur oscillant selon le mode de réalisation de l'invention. Le principe implémenté dans le mode de réalisation qui va être décrit ci- après repose d'une part sur le fait d'utiliser plusieurs balanciers fonctionnant en résonance par un échange d'énergie magnétique entre eux et d'autre part sur le fait d'utiliser au moins deux balanciers d'orientation différente, pour atteindre une solution de régulateur qui sera simplement qualifié de régulateur à résonance tridimensionnelle. Figure 3 shows a side view of the oscillating regulator according to the embodiment of the invention. The principle implemented in the embodiment which will be described below rests on the one hand on the fact of using several balances operating in resonance by a magnetic energy exchange between them and on the other hand on the fact of use at least two differently oriented rockers, to achieve a regulator solution that will simply be called a three-dimensional resonance regulator.
La figure 1 représente ainsi un régulateur oscillant, à résonance tridimensionnelle, selon un mode de réalisation, qui comprend une plateforme 1 formant une pyramide, sur laquelle sont agencés trois systèmes oscillants 20, 30, 40 fonctionnant en résonance, de type balancier- spiral dans ce mode de réalisation. La plateforme 1 est fixe par rapport à la platine supportant les autres composants du mouvement horloger. FIG. 1 thus represents a three-dimensional resonance oscillating regulator, according to one embodiment, which comprises a platform 1 forming a pyramid, on which are arranged three oscillating systems 20, 30, 40 operating in resonance, of the spiral-balance type in this embodiment. The platform 1 is fixed relative to the plate supporting the other components of the watch movement.
La plateforme 1 se présente comme un cube ou une partie de cube, dont trois faces adjacentes, perpendiculaires les unes aux autres, forment des surfaces 2, 3, 4 de support de respectivement chacun des trois systèmes oscillants identiques. The platform 1 is in the form of a cube or part of a cube, three adjacent faces perpendicular to each other forming support surfaces 2, 3, 4 of each of the three identical oscillating systems respectively.
Dans ce mode de réalisation, chaque système oscillant 20, 30, 40 est de type balancier spiral. Le premier balancier spiral est agencé autour d'un axe de rotation 22, monté perpendiculairement à la surface 2. Ce système oscillant comprend de plus de manière connue un balancier, comprenant une serge 23 remplissant la fonction de volant d'inertie, monté mobile en rotation autour de l'axe de rotation 22, par l'intermédiaire d'un ressort en spirale appelé simplement spiral 24. Le balancier-spiral est couramment utilisé dans le domaine de l'horlogerie et ne sera pas plus détaillé ici. De manière similaire, deux autres ensembles de type balancier-spiral sont agencés autour d'axes de rotation 32, 42 agencés respectivement sur les surfaces 3, 4 de la plateforme 1 , et formant deux autres systèmes oscillants du régulateur. In this embodiment, each oscillating system 20, 30, 40 is of the spiral balance type. The first balance spring is arranged around an axis of rotation 22, mounted perpendicular to the surface 2. This system oscillator further comprises in a known manner a balance, comprising a serge 23 fulfilling the function of flywheel, rotatably mounted around the axis of rotation 22, via a spiral spring called simply spiral 24 The sprung balance is commonly used in the field of watchmaking and will not be further detailed here. Similarly, two other sets of sprung-balance type are arranged around axes of rotation 32, 42 respectively arranged on the surfaces 3, 4 of the platform 1, and forming two other oscillating systems of the regulator.
Ainsi, dans ce mode de réalisation, le régulateur oscillant est composé de trois systèmes oscillants complémentaires, qui présentent tous les trois des orientations différentes. Dans le mode de réalisation proposé, ces orientations sont perpendiculaires les unes aux autres. Thus, in this embodiment, the oscillating regulator is composed of three complementary oscillating systems, all of which have different orientations. In the proposed embodiment, these orientations are perpendicular to each other.
En variante, les systèmes oscillants peuvent être montés sur trois faces d'une pyramide non cubique, présentant des faces non perpendiculaires. Cette pyramide peut présenter un axe central et les trois systèmes oscillants peuvent être disposés sur trois plans de la pyramide répartis de manière homogène autour de cet axe central. Selon la variante avantageuse décrite ci-dessus, les trois systèmes oscillants sont agencés sur trois faces contigues d'un cube, c'est-à-dire que les surfaces 2, 3, 4 sont perpendiculaires entre elles et coïncident avec les trois faces d'un cubes. En variante encore, ces surfaces pourraient coïncider avec certaines surfaces d'un polyèdre régulier, non nécessairement cubique. Alternatively, the oscillating systems can be mounted on three sides of a non-cubic pyramid, having non-perpendicular faces. This pyramid may have a central axis and the three oscillating systems may be arranged on three planes of the pyramid evenly distributed around this central axis. According to the advantageous variant described above, the three oscillating systems are arranged on three contiguous faces of a cube, that is to say that the surfaces 2, 3, 4 are perpendicular to each other and coincide with the three faces of the cube. a cubes. In another variant, these surfaces could coincide with certain surfaces of a regular polyhedron, not necessarily cubic.
En remarque, un problème technique d'une telle configuration de régulateur oscillant à résonance tridimensionnelle provient de l'encombrement qu'il nécessite du fait de l'utilisation de plusieurs systèmes oscillants et de leur agencement selon trois dimensions de l'espace. A cet effet, une solution technique consiste à minimiser la hauteur globale du régulateur. Pour cela, les surfaces 2, 3, 4 peuvent être peu inclinées les unes par rapport aux autres, c'est-à-dire que les axes de rotation 22, 32, 42 des systèmes oscillants présenteraient des angles de préférence inférieurs ou égaux à 60 degrés, voire inférieurs ou égaux à 50 degrés. As a remark, a technical problem of such a three-dimensional resonance oscillating controller configuration comes from the size it requires due to the use of several oscillating systems and their arrangement in three dimensions of space. For this purpose, a technical solution consists in minimizing the overall height of the regulator. For that, the surfaces 2, 3, 4 may be slightly inclined relative to each other, that is to say that the axes of rotation 22, 32, 42 of the oscillating systems have angles preferably equal to or less than 60 degrees, even less than or equal to 50 degrees.
Le régulateur selon le mode de réalisation comprend un système oscillant 30 particulier, appelé système oscillant primaire, associé, dans un mouvement d'horlogerie non représenté, à un système de distribution d'énergie conventionnel, qui permet par exemple à une unique roue d'échappement 7 de lui transmettre des impulsions d'énergie maintenant ses oscillations, par l'intermédiaire d'une ancre par exemple, de manière connue. The regulator according to the embodiment comprises a particular oscillating system, called primary oscillating system, associated, in a not shown clockwork movement, with a conventional energy distribution system, which allows for example a single wheel of exhaust 7 to transmit pulses of energy to his oscillations, through an anchor for example, in a known manner.
Ce système oscillant 30 primaire est équipé de composants magnétiques 35, plus particulièrement visibles sur la figure 2. Dans le mode de réalisation représenté, deux petites masselottes magnétiques sont fixées sur la serge 33, à 180 degrés autour de l'axe 32 pour garantir un équilibre dynamique de la serge. De manière similaire, les deux autres systèmes oscillants, appelés systèmes oscillants secondaires, sont aussi équipés de composants magnétiques 25, 45. Dans ce mode de réalisation, ces composants magnétiques sont de même deux masselottes magnétiques équiréparties sur la serge 23, 43 de leurs balanciers. Ainsi, les trois systèmes oscillants, primaire et secondaires, présentent la même structure, incluant des composants magnétiques adaptés pour s'échanger une énergie magnétique. This primary oscillating system is equipped with magnetic components 35, more particularly visible in FIG. 2. In the embodiment shown, two small magnetic weights are fixed on the serge 33, 180 degrees about the axis 32 to guarantee a dynamic balance of the serge. Similarly, the other two oscillating systems, called secondary oscillating systems, are also equipped with magnetic components 25, 45. In this embodiment, these magnetic components are likewise two magnetic flyweights equidistributed on the serge 23, 43 of their rockers. . Thus, the three oscillating systems, primary and secondary, have the same structure, including magnetic components adapted to exchange magnetic energy.
Le fonctionnement de ce régulateur va maintenant être explicité, en référence avec la figure 3 représentant un schéma de principe. Le système oscillant 30 primaire est entraîné par le moteur du mouvement d'horlogerie, par exemple un ressort de barillet, de manière classique. En remarque, ce moteur forme une source d'énergie 5. Le mouvement d'horlogerie comprend avantageusement une seule source d'énergie, et comprend par exemple un seul barillet. Dans le mouvement d'oscillation du le système oscillant primaire, ses composants magnétiques 35 parcourent un chemin répétitif. Sur ce chemin, ils exercent des forces tangentielles de répulsion sur les composants magnétiques 25, 45 de respectivement les deux systèmes oscillants 20, 40 secondaires. Cette force magnétique exercée a pour effet la transmission d'impulsions périodiques transmises à ces systèmes oscillants secondaires, qui sont ainsi entraînés en oscillation de manière stable, grâce à l'énergie magnétique transmise par le système oscillant 30 primaire, et indirectement par la source d'énergie 5 unique du mouvement d'horlogerie. La figure 3 résume ce fonctionnement, et décrit de même un procédé de fonctionnement d'un régulateur de mouvement d'horlogerie : The operation of this regulator will now be explained, with reference to FIG. 3 representing a schematic diagram. The primary oscillating system is driven by the motor of the watch movement, for example a mainspring, in a conventional manner. As a remark, this motor forms a source of energy 5. The watch movement comprises advantageously a single source of energy, and comprises for example a single barrel. In the oscillation motion of the primary oscillating system, its magnetic components travel in a repetitive path. On this path, they exert tangential forces of repulsion on the magnetic components 25, 45 respectively of the two oscillating systems 20, 40 secondary. This magnetic force exerted has the effect of transmitting periodic pulses transmitted to these secondary oscillating systems, which are thus stably driven in oscillation, thanks to the magnetic energy transmitted by the primary oscillating system, and indirectly by the power source. unique energy of the watch movement. FIG. 3 summarizes this operation, and likewise describes a method of operating a watch movement regulator:
- dans une première étape E1 , une source d'énergie 5 transmet des impulsions à un système oscillant 30 primaire, et  in a first step E1, a power source 5 transmits pulses to a primary oscillating system, and
- dans une seconde étape E2, le système oscillant 30 primaire transmet de l'énergie magnétique à deux systèmes oscillants 20, 40 secondaires.  in a second step E2, the primary oscillating system transmits magnetic energy to two secondary oscillating systems 20, 40.
Il en résulte qu'une seule source d'énergie met en mouvement direct et indirect les trois systèmes oscillants orientés selon les trois axes de l'espace.  It follows that a single source of energy puts in direct and indirect motion the three oscillating systems oriented along the three axes of space.
En remarque, les deux systèmes oscillants 20, 40 secondaires sont indépendants l'un de l'autre. Notamment, leurs composants magnétiques 25, 45 n'exercent aucune force (ou une force négligeable) les uns sur les autres. Pour cela, les composants magnétiques 35 du système oscillant 30 primaire sont des aimants permanents, appelés plus simplement aimants, alors que les composants magnétiques 25, 45 des systèmes oscillants 20, 40 secondaires sont de simples éléments magnétisables, qui sont sensibles au champ magnétique exercé par les aimants du système oscillant primaire mais n'exercent quasiment aucune force les uns sur les autres. En variante, les composants magnétiques 25, 45 des systèmes oscillants secondaires sont disposés de manière décalée à 90 degrés sur leur serge 23, 43 respective, de sorte que lors de leurs oscillations, qui sont en phase du fait du phénomène de résonance qui sera précisé ci-après, lorsque l'un d'entre eux se trouve dans sa position la plus proche possible de la serge de l'autre oscillateur secondaire, les composants magnétiques de cette autre serge se trouvent dans une position éloignée de ce composant magnétique, de préférence la position la plus éloignée, de l'ordre de 90 degrés de cette position. As a remark, the two oscillating systems 20, 40 secondary are independent of one another. In particular, their magnetic components 25, 45 exert no force (or negligible force) on each other. For this, the magnetic components 35 of the primary oscillating system are permanent magnets, more simply called magnets, while the magnetic components 25, 45 of the secondary oscillating systems 20, 40 are simple magnetizable elements, which are sensitive to the magnetic field exerted by the magnets of the primary oscillating system but exert almost no force on each other. As a variant, the magnetic components 25, 45 of the secondary oscillating systems are arranged in a 90 degree offset on their respective serge 23, 43, so that during their oscillations, which are in phase because of the resonance phenomenon which will be specified hereinafter, when one of them is in its position as close as possible to the serge of the other secondary oscillator, the magnetic components of this other serge are in a position remote from this magnetic component, from preferably the furthest position, of the order of 90 degrees from this position.
Naturellement, le mode de réalisation a été décrit à titre d'exemple non limitatif, et il existe de nombreuses variantes possibles pour les composants magnétiques de chaque système oscillant. Notamment, il pourrait en variante n'y avoir qu'une seule masselotte magnétique par serge, ou selon une autre variante au moins trois masselottes magnétiques. De préférence, ces masselottes sont réparties de manière homogène sur le système oscillant. Naturally, the embodiment has been described by way of non-limiting example, and there are many possible variants for the magnetic components of each oscillating system. In particular, it could alternatively be only one magnetic weight by serge, or in another variant at least three magnetic flyweights. Preferably, these flyweights are evenly distributed over the oscillating system.
Chaque composant magnétique d'un système oscillant secondaire peut se présenter dans un matériau magnétisable de type ferromagnétique, par exemple une pastille de fer doux revêtue d'une couche d'anticorrosion, par exemple de nickel. Each magnetic component of a secondary oscillating system may be in a magnetizable material of ferromagnetic type, for example a soft iron pellet coated with an anticorrosion layer, for example nickel.
Chaque composant magnétique peut se présenter sous la forme d'un cylindre magnétique, fixé dans un trou pratiqué dans la serge d'un système oscillant. En variante, le composant magnétique peut présenter une autre forme. Each magnetic component can be in the form of a magnetic cylinder, fixed in a hole made in the serge of an oscillating system. Alternatively, the magnetic component may have another shape.
Cette fixation sur le système oscillant peut se faire par chassage, collage, soudage, ou rivetage dans une douille. Cette dernière peut être montée mobile sur le système oscillant, notamment par vissage grâce à un filetage réalisé dans son pourtour. En variante, le composant magnétique peut comprendre une zone filetée pour sa fixation par vissage dans une ouverture filetée correspondante du système oscillant. En remarque, dans les cas d'une fixation par vissage, il est possible de réaliser un réglage fin du système oscillant, en modifiant les tours de vissage. This attachment to the oscillating system can be done by driving, gluing, welding, or riveting in a socket. The latter can be mounted mobile on the oscillating system, in particular by screwing with a thread realized in its periphery. In a variant, the magnetic component may comprise a threaded zone for its fastening by screwing into a corresponding threaded opening of the oscillating system. As a remark, in the case of a fastening by screwing, it is possible to perform a fine adjustment of the oscillating system, by modifying the tightening turns.
Dans le mode de réalisation représenté, chaque composant magnétique, de forme cylindrique, s'étend dans une direction perpendiculaire à l'axe de rotation du système oscillant. En variante, le composant magnétique pourrait être fixé selon une autre orientation, par exemple parallèle à cet axe de rotation. In the embodiment shown, each magnetic component, of cylindrical shape, extends in a direction perpendicular to the axis of rotation of the oscillating system. Alternatively, the magnetic component could be fixed in another orientation, for example parallel to this axis of rotation.
En variante, tout ou partie du système oscillant est directement formé dans un matériau magnétisé, de sorte qu'il n'est plus nécessaire d'ajouter des aimants supplémentaires comme les masselottes décrites précédemment. Ainsi, un composant magnétique peut être formé directement par un composant du système oscillant lui-même, par exemple une partie ou la totalité de la serge. Dans le mode de réalisation décrit, les composants magnétiques exercent des forces de répulsion l'un sur l'autre pour le transfert d'énergie magnétique d'un système oscillant primaire vers un autre secondaire. En variante non représentée, cette force pourrait être une force magnétique d'attraction. As a variant, all or part of the oscillating system is directly formed in a magnetized material, so that it is no longer necessary to add additional magnets such as the weights described above. Thus, a magnetic component can be formed directly by a component of the oscillating system itself, for example a part or the whole of the serge. In the embodiment described, the magnetic components exert repulsive forces on one another for the transfer of magnetic energy from one primary oscillating system to another secondary. As a variant not shown, this force could be a magnetic attraction force.
Les trois systèmes oscillants 20, 30, 40 de ce mode de réalisation sont de même nature, possèdent les mêmes géométries oscillantes. Ils vont tendre naturellement vers des oscillations cohérentes, en phase, par le phénomène appelé résonance dans l'état de la technique. Le système oscillant 30 primaire va partager une partie de son énergie reçue avec deux systèmes oscillants 20, 40 secondaires, par une transmission d'énergie magnétique, tel qu'explicité ci-dessus, et cette architecture va automatiquement induire les oscillations en phase des trois oscillateurs 20, 30, 40, par le phénomène de résonance. Pour optimiser cette résonance et son efficacité, il est choisi volontairement d'avoir au moins deux systèmes oscillants en résonance orientés différemment, ce qui leur donne plus de chance de résister aux influences néfastes extérieures. Notamment, cette configuration permet au régulateur d'être moins dépendant de l'effet de la force de gravitation, d'avoir un fonctionnement moins dépendant de son orientation, ce qui est particulièrement intéressant dans une implémentation au sein d'un boîtier de montre bracelet. En effet, lorsqu'un premier système oscillant du régulateur aura son axe orienté dans une direction défavorable, augmentant les frottements et les résistances à son oscillation naturelle, notamment par exemple lorsque son balancier se trouve dans une direction perpendiculaire (c'est-à-dire que son axe de rotation est horizontal), au moins un autre système oscillant ne sera pas dans cette direction défavorable. L'influence de cet autre système oscillant sur le premier système oscillant va s'opposer à l'influence néfaste de la force de gravitation et le résultat obtenu en sortie du régulateur sera d'une part plus précis que s'il n'y avait que le premier système oscillant, et d'autre part plus stable, puisque moins dépendant de l'orientation du régulateur. Par exemple, dans le mode de réalisation choisi, lorsqu'un balancier sera en position verticale, dans laquelle la pesanteur bouleverse généralement son fonctionnement idéal, au moins un autre balancier sera en position non verticale, et de préférence proche de l'horizontal, de sorte à bénéficier d'un fonctionnement moins, voire pas du tout, perturbé par la pesanteur. Dans tous les cas, lorsque la pesanteur modifie le fonctionnement d'un des balanciers, elle ne modifiera pas celui des autres balanciers de la même manière : le résultat moyen résultant de la résonance entre les différents balanciers restera ainsi peu sensible à la pesanteur. Ainsi, le régulateur utilisé met en œuvre une solution de résonance tridimensionnelle, par le choix d'au moins deux systèmes oscillants fonctionnant en résonance et orientés différemment. Cette résonance tridimensionnelle permet d'obtenir un résultat étonnement plus précis que toutes les solutions de résonance précédemment essayées dans l'état de la technique. The three oscillating systems 20, 30, 40 of this embodiment are of the same nature, have the same oscillating geometries. They will naturally tend towards coherent oscillations, in phase, by the phenomenon called resonance in the state of the art. The primary oscillating system will share part of its energy received with two secondary oscillating systems 20, 40, by a magnetic energy transmission, as explained above, and this architecture will automatically induce the oscillations in phase of the three oscillators 20, 30, 40, by the resonance phenomenon. To optimize this resonance and its efficiency, it is deliberately chosen to have at least two oscillating systems in resonance oriented differently, which gives them more chance of resisting external harmful influences. In particular, this configuration allows the controller to be less dependent on the effect of the gravitational force, to have a less dependent operation of its orientation, which is particularly interesting in an implementation within a wristwatch case . Indeed, when a first oscillating system of the regulator will have its axis oriented in an unfavorable direction, increasing the friction and the resistances to its natural oscillation, in particular for example when its balance is in a perpendicular direction (i.e. say that its axis of rotation is horizontal), at least one other oscillating system will not be in this unfavorable direction. The influence of this other system oscillating on the first oscillating system will oppose the harmful influence of the gravitational force and the result obtained at the output of the regulator will be on the one hand more precise than if there were that the first oscillating system, and secondly more stable, since less dependent on the orientation of the regulator. For example, in the embodiment chosen, when a rocker is in a vertical position, in which gravity generally upsets its ideal operation, at least one other rocker will be in a non-vertical position, and preferably close to the horizontal, of so to benefit from a functioning less, if at all, disturbed by the gravity. In any case, when gravity modifies the operation of one of the pendulums, it will not modify that of the other pendulums in the same way: the average result resulting from the resonance between the different pendulums will thus remain insensitive to gravity. Thus, the regulator used implements a solution of three-dimensional resonance, by the choice of at least two oscillating systems operating in resonance and oriented differently. This three-dimensional resonance makes it possible to obtain an astonishingly more accurate result than all the resonance solutions previously tested in the state of the art.
Dans le mode de réalisation représenté, le régulateur comprend trois systèmes oscillants. D'autres modes de réalisation peuvent être obtenus en choisissant tout autre nombre de systèmes oscillants, au moins deux comme cela a été évoqué ci-dessus. D'autre part, comme cela a été vu, deux systèmes oscillants au moins ne présentent pas la même orientation. De préférence, tous les systèmes oscillants présenteront une orientation différente, et seront répartis de manière homogène dans l'espace pour optimiser leur non-dépendance envers l'orientation du régulateur. Par exemple, leurs axes de rotation peuvent être équirépartis autour d'un certain axe. De manière complémentaire, les composants principaux des systèmes oscillants, comme un balancier, un spiral, un pendule, etc., peuvent aussi être répartis de manière homogène autour de ce même axe. D'autre part, il sera aussi avantageux de prévoir un nombre impair de systèmes oscillants, trois, voire cinq, représentant le meilleur compromis entre la performance et la simplicité. Quel que soit le nombre de systèmes oscillants, il y aura un seul système primaire, tous les autres étant secondaires, recevant de l'énergie magnétique du premier et étant indépendants entre eux. En variante de réalisation, il pourrait y avoir plus d'un seul système primaire, par exemple deux, ou plus. In the embodiment shown, the controller comprises three oscillating systems. Other embodiments can be obtained by choosing any other number of oscillating systems, at least two as mentioned above. On the other hand, as has been seen, at least two oscillating systems do not have the same orientation. Preferably, all the oscillating systems will have a different orientation, and will be distributed homogeneously in space to optimize their non-dependence on the orientation of the regulator. For example, their axes of rotation can be equidistributed around a certain axis. In a complementary manner, the main components of the oscillating systems, such as a balance wheel, a balance spring, a pendulum, etc., can also be distributed homogeneously around this same axis. On the other hand, it will also be advantageous to provide an odd number of oscillating systems, three or even five, representing the best compromise between performance and simplicity. Whatever the number of oscillating systems, there will be only one primary system, all the others being secondary, receiving magnetic energy from the first and being independent of each other. As an alternative embodiment, there could be more than one primary system, for example two or more.
Les systèmes oscillants retenus dans le mode de réalisation décrit sont de type balancier-spiral. Naturellement, n'importe quel autre système oscillant peut en variante être utilisé, comme des systèmes oscillants à base de pendule. Chaque système oscillant est réglable, afin de déterminer le réglage idéal pour leur fonctionnement en résonance. The oscillating systems selected in the embodiment described are of the balance sprung type. Of course, any other oscillating system can alternatively be used, such as oscillating systems based on pendulum. Each oscillating system is adjustable to determine the ideal setting for their resonance operation.
D'autre part, les systèmes oscillants sont reliés entre eux par l'intermédiaire d'une ou en variante de deux plateformes, sur lesquelles une ou des extrémités de leurs axes sont montées. Dans le mode de réalisation, tous les balanciers sont coiffés par un pont de balancier (coque) équipé d'un système de raquetterie permettant le réglage de chacun des spiraux de façon indépendante. Ces plateformes et les systèmes oscillants peuvent aussi former alors un ensemble compact et solidaire, mécaniquement lié, et permettant une transmission d'énergie mécanique entre les systèmes oscillants, complémentaire à la transmission d'énergie magnétique décrite, et favorisant la mise en résonance de ces différents systèmes. L'ensemble du régulateur présente une propriété oscillante propre, une fréquence d'oscillation propre, appelée fréquence de résonance. On the other hand, the oscillating systems are interconnected via one or alternatively two platforms, on which one or more ends of their axes are mounted. In the embodiment, all the rockers are capped by a pendulum bridge (shell) equipped with a racking system for adjusting each spiral independently. These platforms and the oscillating systems can also form a compact and integral assembly, mechanically linked, and allowing a mechanical energy transmission between the oscillating systems, complementary to the magnetic energy transmission described, and promoting the resonance of these different systems. The entire controller has its own oscillating property, a proper oscillation frequency, called the resonance frequency.
Il est ainsi avantageux d'utiliser une plateforme se présentant en une seule pièce, monolithique, et offrant un agencement avec une distance peu importante entre les différents systèmes oscillants. D'autre part, la plateforme sera avantageusement dans un matériau aux propriétés vibratoires favorables, comme du laiton, un métal noble, ou etc. En variante, une plateforme pourrait être composée de parties distinctes fixées entre elles. Certaines extrémités de systèmes oscillants pourraient être liées à une plateforme et d'autres extrémités pourraient rester libres. Tous les systèmes oscillants du régulateur ne sont pas obligatoirement liés à une même plateforme. Enfin, une plateforme spécifique, dédiée, a été prévue dans le mode de réalisation. Toutefois, en variante, la fonction de plateforme peut être remplie par un composant de la pièce d'horlogerie comme une platine, un cadran, un pont, etc. Naturellement, les systèmes oscillants peuvent être disposés sur des plateformes distinctes et indépendantes, ou montés de manière quelconque à proximité les uns des autres, les composants magnétiques suffisant à leur mise en résonance. Il suffit que dans leurs oscillations, des composants magnétiques parcourent une trajectoire telle qu'ils passent à proximité pour exercer une impulsion l'un sur l'autre nécessaire et suffisante au mouvement d'oscillation des systèmes oscillants secondaires. It is thus advantageous to use a platform in one piece, monolithic, and providing an arrangement with a small distance between the various oscillating systems. On the other hand, the platform will advantageously be in a material with favorable vibratory properties, such as brass, a noble metal, and so on. Alternatively, a platform could be composed of separate parts fixed together. Some ends of oscillating systems could be linked to a platform and other ends could remain free. All oscillating systems of the regulator are not necessarily linked to the same platform. Finally, a specific, dedicated platform has been provided in the embodiment. However, as a variant, the platform function can be filled by a component of the timepiece such as a plate, a dial, a bridge, etc. Naturally, the oscillating systems can be arranged on separate and independent platforms, or mounted in any manner close to each other, the components magnetic enough to make them resonate. It suffices that in their oscillations, magnetic components travel in a path such that they pass close to exert an impulse on each other necessary and sufficient oscillation movement secondary oscillating systems.
Avantageusement, hormis les composants magnétiques, une partie, voire la totalité des autres éléments formant le mouvement horloger sont réalisés dans des matériaux peu sensibles aux champs magnétiques. Advantageously, apart from the magnetic components, some or all of the other elements forming the watch movement are made of materials that are not very sensitive to magnetic fields.
Il apparaît que la solution retenue est très simple, notamment en comparaison avec les systèmes complexes de type tourbillon. Dans les modes de réalisation décrits, chaque système oscillant est uniquement mobile en rotation autour de son axe de rotation par rapport au reste de la montre, notamment par rapport à une ou plusieurs plateformes de la montre à laquelle / auxquelles il est lié. Ainsi, l'axe de rotation de chaque système oscillant est fixe par rapport au mouvement d'horlogerie ou la montre. It appears that the solution adopted is very simple, especially in comparison with complex systems of tourbillon type. In the embodiments described, each oscillating system is only rotatable about its axis of rotation relative to the rest of the watch, particularly with respect to one or more platforms of the watch to which it is linked. Thus, the axis of rotation of each oscillating system is fixed with respect to the watch movement or the watch.
D'autre part, la géométrie de la plateforme 1 a été décrite à titre d'exemple non limitatif. Elle pourrait naturellement occuper toute autre forme, être formée de plusieurs surfaces non nécessairement planes, mais courbes, voire d'une seule surface courbée, dès lors qu'elle permet l'assemblage selon des orientations différentes d'au moins deux systèmes oscillants. Les plans perpendiculaires aux axes des différents systèmes oscillants peuvent ainsi former une partie d'un polyèdre irrégulier, c'est-à-dire que certaines surfaces d'un polyèdre irrégulier pourraient être perpendiculaires aux axes de rotation des systèmes oscillants du régulateur. On the other hand, the geometry of the platform 1 has been described by way of non-limiting example. It could naturally occupy any other form, be formed of several surfaces not necessarily planar, but curved, or even a single curved surface, since it allows the assembly in different orientations of at least two oscillating systems. The planes perpendicular to the axes of the different oscillating systems can thus form part of an irregular polyhedron, that is to say that some surfaces of an irregular polyhedron could be perpendicular to the axes of rotation of the oscillating systems of the regulator.
Le régulateur décrit précédemment est particulièrement performant au sein d'une montre bracelet. Naturellement, il reste aussi utile pour toute implémentation plus largement au sein de tout mouvement horloger, pour toute pièce d'horlogerie. The regulator described above is particularly powerful within a wristwatch. Naturally, it also remains useful for any implementation more broadly within any watch movement, for any timepiece.
De plus l'absence de liaison mécanique entre les systèmes oscillants facilite le réglage et améliore donc la précision du régulateur. In addition, the lack of mechanical connection between the oscillating systems facilitates the adjustment and thus improves the accuracy of the regulator.
D'autre part, le principe du régulateur à résonance tridimensionnelle reste compatible avec d'autres approches permettant d'améliorer la précision du régulateur. Ainsi, il peut par exemple être combiné avec une solution de type tourbillon. Finalement, le régulateur à résonance tridimensionnelle permet de fortement réduire, voire annuler, l'effet néfaste de la pesanteur et plus généralement des différents défauts des systèmes oscillants sur l'isochronisme de la montre. On the other hand, the principle of the three-dimensional resonance controller remains compatible with other approaches to improve the accuracy of the regulator. Thus, it can for example be combined with a vortex type solution. Finally, the three-dimensional resonance regulator makes it possible to greatly reduce, or even cancel, the harmful effect of gravity and more generally the various defects of the oscillating systems on the isochronism of the watch.
