Domaine techniqueTechnical area

La présente invention concerne un oscillateur, pour mouvement horloger, comportant un arbre destiné à être monté pivotant sur un élément de bâti du mouvement horloger et solidaire d'un balancier portant au moins un premier aimant bipolaire, agencé à distance de l'arbre et susceptible, en fonction de la position angulaire du balancier, d'être positionné à portée d'un champ magnétique produit par au moins un aimant bipolaire fixe, solidaire d'un support destiné à être assemblé au bâti du mouvement horloger.The present invention relates to an oscillator, for a watch movement, comprising a shaft intended to be pivotally mounted on a frame member of the watch movement and secured to a balance bearing at least a first bipolar magnet, arranged at a distance from the shaft and capable of , depending on the angular position of the balance, to be positioned within range of a magnetic field produced by at least one fixed bipolar magnet, integral with a support intended to be assembled to the frame of the watch movement.

Etat de la techniqueState of the art

Des oscillateurs de ce type sont déjà connus dans le domaine de l'horlogerie. En effet, la fabrication des oscillateurs de type balancier-spiral est délicate à maîtriser, en particulier la réalisation des ressorts-spiraux nécessite un savoir-faire très pointu et peu répandu, ce qui justifie la recherche de solutions alternatives.Oscillators of this type are already known in the field of watchmaking. Indeed, the manufacture of balance-type oscillators spiral is difficult to master, in particular the realization of spiral springs requires a very sharp and uncommon know-how, which justifies the search for alternative solutions.

A titre d'exemple, le brevet EP 1805565 B1 décrit un oscillateur présentant l'ensemble des caractéristiques mentionnées ci-dessus. Plus précisément, ce document décrit la construction d'un oscillateur comportant un balancier portant des aimants bipolaires associés à des aimants bipolaires fixes pour générer des forces de rappel sur le balancier, destinées à reproduire le mouvement typique d'un balancier associé à un ressort-spiral. Ce balancier peut être associé à un échappement à ancre suisse conventionnel pour assurer l'entretien des oscillations à partir d'une source d'énergie mécanique. Les aimants fixes sont agencés autour du balancier, soit dans le même plan que ce dernier, soit dans un plan parallèle.For example, the patent EP 1805565 B1 describes an oscillator having all the characteristics mentioned above. More specifically, this document describes the construction of an oscillator comprising a beam carrying bipolar magnets associated with fixed bipolar magnets for generating restoring forces on the balance, intended to reproduce the typical movement of a balance associated with a spring. spiral. This balance can be associated with a conventional Swiss lever escapement to ensure the maintenance of oscillations from a source of mechanical energy. The fixed magnets are arranged around the balance, either in the same plane as the latter, or in a parallel plane.

Toutefois, les constructions de ce type sont complexes à mettre en oeuvre, notamment pour calibrer correctement les aimants utilisés. En outre, on relèvera que les propriétés magnétiques des aimants courants sont fortement variables avec la température ambiante, ce qui rend difficile la réalisation d'un tel oscillateur présentant de bonnes propriétés chronométriques dans une plage courante d'utilisation en températures. Enfin, on notera également que ce brevet mentionne la nécessité de prévoir des butées mécaniques spécifiques pour empêcher un emballement du balancier, qui pourrait par exemple survenir en cas de choc.However, constructions of this type are complex to implement, in particular to correctly calibrate the magnets used. In addition, it will be noted that the magnetic properties of current magnets are highly variable with ambient temperature, which makes it difficult to achieve such an oscillator having good chronometric properties in a current range of use in temperatures. Finally, it will also be noted that this patent mentions the need to provide specific mechanical stops to prevent runaway of the balance, which could for example occur in case of impact.

D'autres solutions similaires ont été présentées, notamment pour répondre à la problématique des variations de température ambiante, mais elles sont généralement encore plus complexes que celle qui vient d'être discutée. Ainsi, par exemple, la demande de brevet WO 2011/051497 A1 décrit une amélioration de l'oscillateur mentionné précédemment, consistant à agencer une culasse ferromagnétique autour du balancier pour canaliser les flux magnétiques impliqués.Other similar solutions have been presented, particularly to address the problem of ambient temperature variations, but they are generally even more complex than the one just discussed. Thus, for example, the patent application WO 2011/051497 A1 describes an improvement of the aforementioned oscillator, consisting of arranging a ferromagnetic cylinder head around the balance to channel the magnetic flux involved.

Divulgation de l'inventionDisclosure of the invention

Un but principal de la présente invention est de proposer une construction permettant de réaliser un oscillateur pour mouvement horloger, tel que décrit plus haut, ne comportant pas de ressort-spiral, et offrant de bons résultats chronométriques tout en présentant une structure simple, robuste et peu sensible aux variations de la température ambiante ou aux chocs.A main object of the present invention is to propose a construction making it possible to produce an oscillator for a watch movement, as described above, having no spring-coil, and offering good chronometric results while presenting a simple, robust and not very sensitive to changes in ambient temperature or shocks.

A cet effet, la présente invention concerne plus particulièrement un oscillateur du type mentionné plus haut, caractérisé par le fait que l'aimant bipolaire fixe est situé sur la trajectoire du premier aimant bipolaire, telle qu'elle est définie par le pivotement du balancier, en étant agencé sur le support de telle manière que, lorsque le premier aimant bipolaire se rapproche de l'aimant bipolaire fixe, des polarités identiques soient situées en regard l'une de l'autre pour donner lieu à une force de répulsion. En outre, l'oscillateur selon l'invention comporte un dispositif de liaison, destiné à établir une liaison cinématique entre une source d'énergie du mouvement horloger et l'arbre du balancier, agencé de telle manière que le balancier soit susceptible de présenter un mouvement oscillant périodique entretenu.To this end, the present invention relates more particularly to an oscillator of the type mentioned above, characterized in that the fixed bipolar magnet is located on the path of the first bipolar magnet, as defined by the pivoting of the balance, by being arranged on the support such that when the first bipolar magnet approaches the fixed bipolar magnet, identical polarities are located facing each other to give rise to a repulsive force. In addition, the oscillator according to the invention comprises a connecting device, intended to establish a kinematic connection between a power source of the watch movement and the balance shaft, arranged in such a way that the balance is likely to present a periodic oscillating motion maintained.

Grâce à ces caractéristiques, et contre toute attente, le principe de base de la répulsion survenant entre deux aimants approchés l'un de l'autre, avec des polarités identiques en regard l'une de l'autre, permet de générer une force de rappel adaptée à la mise en oeuvre d'un oscillateur pour mouvement horloger. En outre, l'aimant fixe remplit directement la fonction de butée mécanique supprimant tout risque d'emballement du balancier en cas de choc.Thanks to these characteristics, and against all odds, the basic principle of the repulsion occurring between two magnets approaching one another, with identical polarities facing each other, makes it possible to generate a force of recall adapted to the implementation of an oscillator for watch movement. In addition, the fixed magnet directly fulfills the function of mechanical stop eliminating any risk of runaway of the balance in case of impact.

Selon un mode de réalisation préféré non limitatif, on peut prévoir que le dispositif de liaison comporte une cheville solidaire de l'arbre de balancier et agencée pour coopérer avec un échappement, destiné à présenter une liaison cinématique avec la source d'énergie du mouvement horloger, pour entretenir les oscillations du balancier. Grâce à ces caractéristiques, l'oscillateur selon la présente invention peut être facilement mis en oeuvre en relation avec un calibre horloger existant, sans nécessiter de modifications trop importantes.According to a preferred non-limiting embodiment, it can be provided that the connecting device comprises a peg secured to the rocker shaft and arranged to cooperate with an escapement, intended to present a kinematic connection with the energy source of the watch movement. , to maintain oscillations of the pendulum. Thanks to these characteristics, the oscillator according to the present invention can be easily implemented in relation to an existing clock caliber, without requiring too much changes.

De manière générale, on peut prévoir que le balancier porte un deuxième aimant bipolaire similaire - et agencé de manière similaire - au premier aimant bipolaire pour coopérer avec l'aimant bipolaire fixe en alternance avec le premier aimant bipolaire, les premier et deuxième aimants bipolaires présentant entre eux un écart angulaire compris entre 20 et 180 degrés. Dans ce cas, il peut être avantageux de prévoir que l'un au moins des premier et deuxième aimants bipolaires est assemblé au balancier de telle manière qu'il peut être déplacé pour ajuster la valeur de l'écart angulaire.Generally speaking, it is possible for the rocker arm to carry a second bipolar magnet similar - and similarly arranged - to the first bipolar magnet to cooperate with the fixed bipolar magnet alternating with the first bipolar magnet, the first and second bipolar magnets having between them an angular difference between 20 and 180 degrees. In this case, it may be advantageous to provide that at least one of the first and second bipolar magnets is assembled to the balance so that it can be moved to adjust the value of the angular difference.

La présente invention concerne également un mouvement horloger comportant un oscillateur répondant aux caractéristiques ci-dessus, ainsi qu'une pièce d'horlogerie munie d'un tel mouvement horloger.The present invention also relates to a watch movement comprising an oscillator meeting the above characteristics, as well as a timepiece equipped with such a watch movement.

La représentation du mouvement horloger est simplifiée sur les figures pour faciliter la compréhension des caractéristiques de l'oscillateur selon l'invention.The representation of the watch movement is simplified in the figures to facilitate understanding of the characteristics of the oscillator according to the invention.

Le mouvement horloger peut être un calibre existant qui serait légèrement modifié pour y implanter l'oscillateur selon l'invention ou, en alternative, il peut être un nouveau calibre développé spécifiquement, sans sortir du cadre de l'invention.The watch movement may be an existing caliber that would be slightly modified to implant the oscillator according to the invention or, alternatively, it may be a new caliber developed specifically, without departing from the scope of the invention.

Le mouvement horloger comporte un bâti, notamment ici une platine 2 usinée de manière conventionnelle pour supporter tout ou partie des mobiles du mouvement. En particulier, la platine supporte typiquement une source d'énergie, comme un ressort logé dans un barillet (non illustré), destinée à entretenir les oscillations de l'oscillateur 1 par l'intermédiaire d'un rouage de finissage (non illustré).The watch movement comprises a frame, in particular here a plate 2 machined in a conventional manner to support all or part of the motions of the movement. In particular, the board typically supports a power source, such as a spring housed in a barrel (not shown), for maintaining the oscillations of the oscillator 1 through a finishing train (not shown).

L'oscillateur 1 comporte un balancier 4 de forme générale sensiblement conventionnelle, c'est-à-dire qu'il comprend un moyeu 6 à partir duquel s'étend au moins un bras 8 permettant de relier une serge 10 au moyeu.The oscillator 1 comprises a rocker 4 of substantially conventional general shape, that is to say that it comprises a hub 6 from which extends at least one arm 8 for connecting a serge 10 to the hub.

Le balancier 4 est solidaire d'un arbre 12 par lequel il est monté pivotant sur le bâti du mouvement horloger.The rocker 4 is secured to a shaft 12 by which it is pivotally mounted on the frame of the watch movement.

Une première extrémité 14 de l'arbre 12 est ici pivotée dans un premier palier ménagé dans la platine 2, tandis que l'autre extrémité 16 de l'arbre est pivotée dans un deuxième palier ménagé sur un pont 18 de balancier, lui-même assemblé à la platine 2.A first end 14 of the shaft 12 is here pivoted in a first bearing formed in the plate 2, while the other end 16 of the shaft is pivoted in a second bearing formed on a balance bridge 18, itself assembled to the stage 2.

Selon la présente invention, le balancier 4 porte au moins un premier aimant bipolaire 20, agencé à distance de l'arbre 12. Plus précisément, l'aimant 20 est ici logé dans une extension 21 ménagée en surépaisseur sur la serge 10 du balancier 4. L'aimant 20 présente une orientation magnétique sensiblement tangentielle en référence au balancier 4, autrement dit, ses première et seconde faces 22 et 24 présentent des polarités opposées. Par exemple, la première face 22 peut être associée au pôle Nord de l'aimant 20 tandis que la seconde face 24 peut être associée à son pôle Sud.According to the present invention, the rocker 4 carries at least a first bipolar magnet 20, arranged at a distance from the shaft 12. More precisely, the magnet 20 is here housed in an extension 21 formed in thickened on the strut 10 of the balance 4 The magnet 20 has an orientation Magnetically substantially tangential with reference to the balance 4, in other words, its first and second faces 22 and 24 have opposite polarities. For example, the first face 22 may be associated with the north pole of the magnet 20 while the second face 24 may be associated with its south pole.

Par ailleurs, le pont 18 de balancier porte un support 26 agencé sur le pont de telle manière que son orientation angulaire par rapport à ce dernier peut être ajustée dans un but qui sera exposé plus loin. Le support 26 porte un aimant bipolaire fixe 28 agencée de telle manière qu'il est situé à proximité de la serge 10 du balancier 4.Furthermore, the balance bridge 18 carries a support 26 arranged on the bridge so that its angular orientation relative to the latter can be adjusted for a purpose to be explained later. The support 26 carries a fixed bipolar magnet 28 arranged in such a manner that it is located near the serge 10 of the balance 4.

Ainsi, le premier aimant bipolaire 20 est susceptible, en fonction de la position angulaire du balancier 4, d'être positionné à portée du champ magnétique produit par l'aimant bipolaire fixe 28.Thus, the first bipolar magnet 20 is capable, depending on the angular position of the rocker 4, to be positioned within range of the magnetic field produced by the fixed bipolar magnet 28.

En effet, l'agencement du support 26 sur le pont 18 de balancier est réalisé de telle manière que l'aimant bipolaire fixe 28 soit situé sur la trajectoire du premier aimant bipolaire 20, telle qu'elle est définie par le pivotement du balancier 4. Cette trajectoire présente sensiblement la forme d'une portion de tore adjacente à la serge 10 du balancier 4 et située dans un plan parallèle à ce dernier.Indeed, the arrangement of the support 26 on the balance bridge 18 is made such that the fixed bipolar magnet 28 is located on the path of the first bipolar magnet 20, as defined by the pivoting of the balance 4 This trajectory has substantially the shape of a portion of torus adjacent to the serge 10 of the balance 4 and located in a plane parallel to the latter.

En outre, l'aimant bipolaire fixe 28 est agencé sur le support 26 de telle manière que, lorsque le premier aimant bipolaire 20 s'approche de lui, des polarités identiques soient situées en regard l'une de l'autre pour donner lieu à une force de répulsion. Cet agencement permet de générer des forces de rappel sur le balancier, lorsqu'il pivote, destinées à reproduire le mouvement typique d'un balancier associé à un ressort-spiral.In addition, the fixed bipolar magnet 28 is arranged on the support 26 in such a way that, when the first bipolar magnet 20 approaches it, identical polarities are located opposite one another to give rise to a repulsive force. This arrangement makes it possible to generate restoring forces on the balance, when it pivots, intended to reproduce the typical movement of a balance associated with a spiral spring.

On notera que l'extension 21 peut, en alternative, être disposée radialement sur la serge 10 plutôt que suivant une direction axiale, sans sortir du cadre de l'invention. Une telle alternative permet de réduire l'encombrement du balancier dans la direction de son épaisseur mais augmente son diamètre global. La forme et les dimensions du support 26 devront bien entendu être adaptées à l'implantation de l'extension 21 sur le balancier 4 et l'homme du métier ne rencontrera pas de difficulté particulière pour adapter ces éléments en fonction de ses propres besoins.Note that the extension 21 may, alternatively, be arranged radially on the serge 10 rather than in an axial direction, without departing from the scope of the invention. Such an alternative reduces the size of the balance in the direction of its thickness but increases its overall diameter. The shape and dimensions of the support 26 must of course be adapted to the implantation of the extension 21 on the balance 4 and the skilled person will not encounter any difficulty particular to adapt these elements according to their own needs.

Par ailleurs, l'oscillateur 1 selon la présente invention comporte un dispositif de liaison, destiné à établir une liaison cinématique entre la source d'énergie du mouvement horloger et l'arbre 12 de balancier, agencé de telle manière que le balancier soit susceptible de présenter un mouvement oscillant périodique entretenu.Furthermore, the oscillator 1 according to the present invention comprises a connecting device, intended to establish a kinematic connection between the energy source of the watch movement and the balance shaft 12, arranged in such a way that the pendulum is capable of present a periodic oscillating motion maintained.

Comme mentionné plus haut, le mouvement horloger comporte typiquement un rouage de finissage assurant la liaison entre la source d'énergie et l'oscillateur.As mentioned above, the watch movement typically comprises a finishing gear train ensuring the connection between the power source and the oscillator.

Seule une roue d'échappement 30, entraînée par le rouage de finissage, a été représentée sur les figures. La roue d'échappement 30 reçoit en permanence un couple par son pignon (non visible), sous l'effet de l'énergie libérée par la source d'énergie du mouvement horloger, tendant toujours à la faire tourner dans un même sens de rotation prédéfini.Only an escape wheel 30, driven by the work train, has been shown in the figures. The escape wheel 30 constantly receives a torque by its pinion (not visible), under the effect of the energy released by the energy source of the watch movement, always tending to rotate in the same direction of rotation predefined.

La roue d'échappement coopère de manière conventionnelle avec une ancre 32 pivotée sur le bâti du mouvement horloger. L'ancre 32 présente typiquement une fourchette 34 agencée pour coopérer avec la roue d'échappement 30 et un dard 36 agencé pour coopérer avec une cheville de plateau (non visible) solidaire du balancier 4.The escape wheel cooperates conventionally with an anchor 32 pivoted on the frame of the watch movement. The anchor 32 typically has a fork 34 arranged to cooperate with the escape wheel 30 and a dart 36 arranged to cooperate with a plateau pin (not visible) integral with the balance 4.

Ainsi, le balancier 4 actionne périodiquement l'ancre 32 pour la faire pivoter et libérer la roue d'échappement 30, tandis que cette dernière fournit de petites impulsions en retour à l'ancre pour entretenir les oscillations du balancier.Thus, the rocker 4 periodically actuates the anchor 32 to rotate it and release the escape wheel 30, while the latter provides small impulses back to the anchor to maintain oscillations of the balance.

Bien entendu, d'autres réalisations sont envisageables en ce qui concerne le dispositif de liaison, sans sortir du cadre de l'invention.Of course, other embodiments are possible with regard to the connecting device, without departing from the scope of the invention.

A titre d'exemple, on peut prévoir un mécanisme du type de ceux utilisés dans les mécanismes de remontage automatique à double sens mettant en oeuvre un inverseur simple fonctionnant avec un renvoi monté sur une bascule pour engrener alternativement avec des première et seconde roues dentées, directement pour l'une et via un renvoi pour l'autre. Un tel mécanisme est par exemple décrit dans l'ouvrage intitulé " Théorie d'horlogerie", de C.-A. Reymondin et al., édité par la Fédération des Ecoles Techniques (Suisse), ISBN 2-940025-10-X" à la page 178 (fig. 8-30 et 8-31 ), dont l'enseignement est incorporé par référence dans la présente divulgation. Le renvoi monté sur bascule change de roue dentée à chaque changement de sens de rotation du balancier pour permettre une transmission d'énergie au balancier toutes les alternances.By way of example, it is possible to provide a mechanism of the type of those used in the two-way automatic winding mechanisms using a simple inverter operating with a gear mounted on a rocker to mesh alternately with first and second gears, directly for one and via a referral for the other. Such a mechanism is for example described in the book entitled " Theorie d'horlogerie ", by AC Reymondin et al., Published by the Federation of Technical Schools (Switzerland), ISBN 2-940025-10-X "on page 178 (Figs 8-30 and 8-31 ), the teaching of which is incorporated by reference in the present disclosure. The rocker mounted gear change gear wheel at each change of direction of rotation of the balance to allow a transmission of energy to the balance all alternations.

L'homme du métier pourra mettre en oeuvre des variantes de réalisation du dispositif de liaison sans difficulté et sans sortir du cadre de l'invention.Those skilled in the art can implement alternative embodiments of the connecting device without difficulty and without departing from the scope of the invention.

De manière générale, il est possible de prévoir des variantes de réalisation pour l'oscillateur 1.In general, it is possible to provide variant embodiments for the oscillator 1.

Ainsi, par exemple, il est possible de prévoir que le balancier 4 porte un deuxième aimant bipolaire 40 logé dans une deuxième extension 41 similaire à l'extension 21. Le deuxième aimant 40 présente alors la même orientation que le premier aimant 20 de telle manière que les aimants 20 et 40 coopèrent en alternance avec l'aimant bipolaire fixe 28 pour donner lieu, chacun son tour, à une force de répulsion permettant d'inverser le sens de rotation du balancier 4. En outre, le fait de prévoir deux aimants sur le balancier permet d'ajuster l'amplitude des oscillations du balancier, en modifiant l'écart angulaire entre les deux aimants.Thus, for example, it is possible to provide that the balance 4 carries a second bipolar magnet 40 housed in a second extension 41 similar to the extension 21. The second magnet 40 then has the same orientation as the first magnet 20 in such a way that the magnets 20 and 40 cooperate alternately with the fixed bipolar magnet 28 to give rise, in turn, to a repulsive force for reversing the direction of rotation of the balance 4. In addition, the provision of two magnets on the pendulum makes it possible to adjust the amplitude of the oscillations of the balance, by modifying the angular difference between the two magnets.

De manière préférée, on peut prévoir un écart angulaire de l'ordre de 20 à 180 degrés, pour que l'amplitude des oscillations du balancier 4 soit comprise sensiblement entre 180 et 340 degrés. Encore plus préférablement, l'écart angulaire peut être compris entre 40 et 160 degrés.Preferably, an angular difference of the order of 20 to 180 degrees can be provided so that the amplitude of the oscillations of the balance 4 is substantially between 180 and 340 degrees. Even more preferably, the angular difference can be between 40 and 160 degrees.

Par ailleurs, il ressort des figures que le balancier 4 comprend ici un bras unique 8 présentant une étendue angulaire importante pour assurer un équilibrage du balancier du point de vue des masses, notamment pour équilibrer la masse des extensions 21 et 41. Bien entendu, d'autres formes et/ou solutions pourront être retenues pour assurer l'équilibrage du balancier, sans sortir du cadre de la présente invention.Furthermore, it is apparent from the figures that the balance 4 here comprises a single arm 8 having a large angular extent to balance the balance from the point of view of the masses, in particular to balance the mass of the extensions 21 and 41. Of course, d Other shapes and / or solutions may be retained to balance the balance, without departing from the scope of the present invention.

En ce qui concerne le support 26, il peut comporter une base 50, munie d'un trou 52 pour assurer son assemblage au pont 18, à partir de laquelle s'étendent des premier et deuxième bras 54, 56 destinés à être positionnés avec une orientation angulaire adaptée en référence au balancier 4, lui-même orienté angulairement par rapport à l'ancre 32 (en tout cas, la cheville de plateau est positionnée pour présenter des oscillations sensiblement symétriques en référence à la droite passant par l'arbre de balancier et l'axe de rotation de l'ancre).As regards the support 26, it may comprise a base 50, provided with a hole 52 to ensure its assembly to the bridge 18, from which extend first and second arms 54, 56 intended to be positioned with a angular orientation adapted with reference to the balance 4, itself oriented angularly with respect to the anchor 32 (in in any case, the plateau pin is positioned to present substantially symmetrical oscillations with reference to the line passing through the balance shaft and the axis of rotation of the anchor).

Le premier bras 54 permet de faciliter la préhension du support 26 pour en modifier l'orientation angulaire sur le pont 18, de manière similaire aux raquettes d'échappement conventionnelles.The first arm 54 facilitates the gripping of the support 26 to change the angular orientation on the bridge 18, similar to the conventional exhaust rackets.

Le deuxième bras 56 présente un logement, pour l'aimant bipolaire fixe 28, disposé ici perpendiculairement à la direction principale du deuxième bras 56 de telle manière que l'aimant fixe 28 est finalement orienté sensiblement tangentiellement en référence à la serge 10 du balancier 4.The second arm 56 has a housing, for the fixed bipolar magnet 28, disposed here perpendicularly to the main direction of the second arm 56 so that the fixed magnet 28 is finally oriented substantially tangentially with reference to the beam 10 of the balance 4 .

Grâce à ces caractéristiques et aux possibilités d'ajustement de l'orientation du support 26, non seulement l'aimant fixe 28 peut être positionné précisément sur la trajectoire des aimants portés par le balancier, mais il permet en outre de définir une butée mécanique offrant une sécurité contre l'emballement du balancier en cas de choc.Thanks to these characteristics and to the possibilities of adjusting the orientation of the support 26, not only the fixed magnet 28 can be positioned precisely on the trajectory of the magnets carried by the balance, but it also makes it possible to define a mechanical stop offering a safety against the runaway of the balance in case of shock.

On notera que les aimants bipolaires utilisés pour la mise en oeuvre de la présente invention peuvent être réalisés à partir d'aimants de type standard, disponible dans le commerce, et l'homme du métier ne rencontrera pas de difficulté particulière pour choisir des aimants adaptés à ses besoins.It should be noted that the bipolar magnets used for the implementation of the present invention can be made from magnets of standard type, commercially available, and those skilled in the art will not encounter any particular difficulty in choosing suitable magnets. to his needs.

On notera également que la construction selon l'invention permet de simplifier la conception de l'oscillateur en référence aux solutions connues et rend en outre l'oscillateur moins sensible aux variations de la température ambiante.Note also that the construction according to the invention simplifies the design of the oscillator with reference to known solutions and also makes the oscillator less sensitive to changes in ambient temperature.

La description qui précède s'attache à décrire un mode de réalisation particulier à titre d'illustration non limitative et, l'invention n'est pas limitée à la mise en oeuvre de certaines caractéristiques particulières qui viennent d'être décrites, comme par exemple les formes illustrées et décrites pour le balancier ou les différents supports décrits en relation avec les différents aimants. On notera également que l'homme du métier pourra également adapter le présent enseignement pour réaliser un dispositif de liaison entre le balancier et la source d'énergie du mouvement horloger répondant à ses propres besoins sans sortir du cadre de l'invention.The foregoing description attempts to describe a particular embodiment by way of non-limiting illustration and the invention is not limited to the implementation of certain particular features which have just been described, for example the shapes illustrated and described for the pendulum or the various supports described in relation to the different magnets. Note also that the skilled person can also adapt the present teaching to achieve a connecting device between the balance and the energy source of the watch movement responding to its own needs without departing from the scope of the invention.

De manière générale, l'homme du métier ne rencontrera pas de difficulté particulière pour adapter le contenu de la présente divulgation à ses propres besoins et mettre en oeuvre un oscillateur pour mouvement horloger comportant un balancier portant au moins un premier aimant associé à un aimant fixe agencé sur la trajectoire de l'aimant porté par le balancier pour générer une répulsion jouant le rôle de force de rappel lors de la rotation du balancier, sans sortir du cadre de la présente invention.In general, the person skilled in the art will not encounter any particular difficulty in adapting the content of the present disclosure to his own needs and implementing an oscillator for a watch movement comprising a balance bearing at least a first magnet associated with a fixed magnet. arranged on the trajectory of the magnet carried by the balance to generate a repulsion acting as a restoring force during the rotation of the balance, without departing from the scope of the present invention.
