Description

Domaine techniqueTechnical area

La présente invention concerne un mouvement horloger du type à remontage automatique comportant un bâti portant un organe moteur, relié cinématiquement à un oscillateur mécanique pour entretenir ses oscillations notamment par l'intermédiaire d'une roue d'échappement, et un mécanisme de remontage automatique comprenant une masse oscillante agencée pour alimenter l'organe moteur en énergie.The present invention relates to a watch movement of the self-winding type comprising a frame carrying a driving member, kinematically connected to a mechanical oscillator to maintain its oscillations, in particular via an escape wheel, and an automatic winding mechanism comprising an oscillating mass arranged to supply the motor member with energy.

Etat de la techniqueState of the art

La plupart des mouvements horlogers du type à remontage automatique connus de l'art antérieur répondent à la définition ci-dessus.Most self-winding type watch movements known from the prior art meet the above definition.

Un certain nombre de ces mouvements horlogers connus ont été conçus pour limiter l'influence de la gravité sur le fonctionnement de l'oscillateur mécanique.A number of these known watch movements have been designed to limit the influence of gravity on the operation of the mechanical oscillator.

C'est ainsi que, par exemple, l'échappement à tourbillon a été inventé au XVIIIème siècle par A.-L. Breguet, cette invention étant toujours d'actualité aujourd'hui.Thus, for example, the tourbillon escapement was invented in the 18th century by A.-L. Breguet, this invention is still relevant today.

Plus récemment, la société portant le nom de l'illustre inventeur mentionné ci-dessus a commercialisé un mouvement comportant un double tourbillon monté sur une platine secondaire effectuant un tour sur elle-même en référence à la platine principale du mouvement.More recently, the company bearing the name of the illustrious inventor mentioned above has marketed a movement comprising a double tourbillon mounted on a secondary plate performing a turn on itself with reference to the main plate of the movement.

La manufacture Zénith International S.A. a par ailleurs proposé une solution alternative pour tenter d'améliorer la marche des mouvements de montre, en montant l'oscillateur mécanique sur un bâti secondaire relié au bâti principal du mouvement par un joint à cardans. Grâce à cette construction, l'oscillateur mécanique, composé d'un balancier associé à un ressort spiral, est maintenu dans un plan horizontal en permanence.The Zénith International S.A. factory has also proposed an alternative solution to try to improve the movement of watch movements, by mounting the mechanical oscillator on a secondary frame connected to the main frame of the movement by a cardan joint. Thanks to this construction, the mechanical oscillator, composed of a balance associated with a spiral spring, is maintained in a horizontal plane permanently.

La demande de brevet EP1615085A1 décrit un mouvement horloger à remontage automatique comportant un oscillateur mécanique et une roue d'échappement montés pivotants dans la masse oscillante de remontage du mouvement. Ce système emploie cependant deux différentiels de construction complexe avec des satellites à engrenages coniques. Il existe un besoin pour réaliser un système plus simple.The patent application EP1615085A1 discloses a self-winding watch movement comprising a mechanical oscillator and an escape wheel pivotally mounted in the oscillating winding mass of the movement. This system, however, employs two complex construction differentials with bevel gear satellites. There is a need to achieve a simpler system.

La demande de brevet EP1826633 A1 décrit une montre à remontage automatique comportant un indicateur de la réserve de marche monté sur la masse oscillante.The patent application EP1826633 A1 describes a self-winding watch having an indicator of the power reserve mounted on the oscillating weight.

Divulgation de l'inventionDisclosure of the invention

Un but principal de la présente invention est de proposer une alternative aux constructions connues de l'art antérieur, en proposant un mouvement horloger présentant une construction originale, notamment pour le montage de l'oscillateur mécanique, permettant de limiter l'influence de la gravité sur le fonctionnement de ce dernier. L'invention est définie par la revendication 1 annexée.A main object of the present invention is to propose an alternative to the known constructions of the prior art, by proposing a watch movement having an original construction, particularly for the mounting the mechanical oscillator, to limit the influence of gravity on the operation of the latter. The invention is defined by appended claim 1.

A cet effet, la présente invention concerne plus particulièrement un mouvement horloger du type mentionné plus haut, caractérisé par le fait que l'oscillateur mécanique et la roue d'échappement sont montés pivotants sur la masse oscillante.For this purpose, the present invention relates more particularly to a watch movement of the type mentioned above, characterized in that the mechanical oscillator and the escape wheel are pivotally mounted on the oscillating mass.

Grâce à ces caractéristiques, l'oscillateur mécanique présente un grand nombre de positions différentes en fonction du temps lorsque le mouvement horloger est monté dans une pièce d'horlogerie portée, ce qui permet de limiter l'influence de la gravité sur son fonctionnement.Thanks to these characteristics, the mechanical oscillator has a large number of different positions as a function of time when the watch movement is mounted in a worn timepiece, which limits the influence of gravity on its operation.

De manière préférée, le mouvement horloger selon l'invention comporte un engrenage différentiel présentant une première entrée, reliée cinématiquement à l'organe moteur, une seconde entrée, reliée cinématiquement à la masse oscillante, et une sortie, reliée cinématiquement à la roue d'échappement pour, d'une part, lui transmettre de l'énergie à partir de l'organe moteur et, d'autre part, compenser les mouvements de la masse oscillante en référence au bâti.Preferably, the watch movement according to the invention comprises a differential gear having a first input, kinematically connected to the drive member, a second input, kinematically connected to the oscillating weight, and an output, kinematically connected to the gear wheel. exhaust to, on the one hand, transmit energy from the drive member and, on the other hand, compensate for the movements of the oscillating mass with reference to the frame.

Selon un mode de réalisation préféré, l'engrenage différentiel comporte un porte-satellite monté rotatif sur le bâti, un satellite monté rotatif sur le porte-satellite formant la première entrée, le porte-satellite portant une denture reliée cinématiquement à la masse oscillante pour former la seconde entrée et, une roue de sortie libre en rotation par rapport au porte-satellite, reliée cinématiquement à la roue d'échappement pour former la sortie de l'engrenage différentiel.According to a preferred embodiment, the differential gear comprises a carrier rotatably mounted on the frame, a satellite rotatably mounted on the planet carrier forming the first input, the carrier having a toothing kinematically connected to the oscillating weight for forming the second input and, a free output wheel rotating relative to the carrier, kinematically connected to the escape wheel to form the output of the differential gear.

La roue de sortie peut engrener avec la roue d'échappement, soit directement, soit via une roue intermédiaire qui peut, éventuellement, être solidaire d'une cage de tourbillon portant la roue d'échappement et l'oscillateur mécanique.The output wheel may mesh with the escape wheel, either directly or via an intermediate wheel which may optionally be integral with a vortex cage carrying the escape wheel and the mechanical oscillator.

En outre, de manière préféré, le mouvement comporte un premier renvoi monté rotatif sur le bâti et agencé, d'une part, en prise avec un pignon solidaire de la masse oscillante et, d'autre part, en prise avec la denture du porte-satellite.In addition, preferably, the movement comprises a first return rotatably mounted on the frame and arranged, on the one hand, in engagement with a pinion integral with the oscillating mass and, on the other hand, in engagement with the toothing of the door -satellite.

De manière avantageuse, le rapport d'engrenage entre le pignon solidaire de la masse oscillante et la denture du porte-satellite est avantageusement choisi de telle manière que, lorsque la roue d'échappement est fixe, le porte-satellite présente à chaque instant un déplacement angulaire identique à celui de la masse oscillante.Advantageously, the gear ratio between the pinion integral with the oscillating mass and the toothing of the planet carrier is advantageously chosen in such a way that, when the escape wheel is stationary, the planet carrier presents at every moment a angular displacement identical to that of the oscillating mass.

Il peut être de plus prévu que le satellite comporte une première roue reliée cinématiquement à l'organe moteur, par l'intermédiaire d'un second renvoi, et une seconde roue reliée cinématiquement à un pignon libre sur le porte-satellite, éventuellement par l'intermédiaire d'un renvoi inverseur.It can be further provided that the satellite comprises a first wheel kinematically connected to the drive member, via a second reference, and a second wheel kinematically connected to a free pinion on the planet carrier, possibly by intermediate of an inverting reference.

Dans ce cas, il est avantageux de prévoir un tube creux solidaire du bâti, à l'intérieur duquel est logé le second renvoi et sur lequel est monté pivotant le porte-satellite. La masse oscillante peut également être préférablement montée pivotante sur le tube creux.In this case, it is advantageous to provide a hollow tube integral with the frame, inside which is housed the second reference and on which is pivotally mounted the carrier. The oscillating mass may also preferably be pivotally mounted on the hollow tube.

Grâce à ces caractéristiques, le mouvement présente une construction à la fois originale, compacte, et permettant de garantir une bonne marche de l'oscillateur mécanique.Thanks to these characteristics, the movement presents a construction that is both original and compact, and that guarantees a smooth running of the mechanical oscillator.

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

La figure 1 représente une vue de face simplifiée, d'un mouvement horloger selon un mode de réalisation préféré de la présente invention.The figure 1 represents a simplified front view of a watch movement according to a preferred embodiment of the present invention.

Seuls les éléments contribuant à l'invention ont été représentés pour plus de clarté.Only the elements contributing to the invention have been represented for clarity.

Le mouvement horloger, du type à remontage automatique, comporte un mécanisme de remontage automatique agencé pour alimenter en énergie un organe moteur, tel un ressort de barillet (non représenté). Le mécanisme de remontage automatique comprend notamment une masse oscillante 1 montée rotative au centre du mouvement, suivant un axe X1.The watch movement, of the self-winding type, comprises an automatic winding mechanism arranged to supply power to a motor member, such as a mainspring (not shown). The automatic winding mechanism comprises in particular an oscillating mass 1 rotatably mounted at the center of the movement along an axis X1.

La masse oscillante 1 comporte un bâti 2 par lequel elle est reliée au bâti principal du mouvement, à savoir ici à la platine 4. Le bâti 2 de la masse oscillante présente une section en forme de J, tel que cela ressort mieux de la figure 2, à l'intérieur duquel est logé un tourbillon 5.The oscillating mass 1 comprises a frame 2 by which it is connected to the main frame of the movement, namely here to the plate 4. The frame 2 of the oscillating mass has a J-shaped section, as it is more clearly apparent from the figure 2 , inside which is housed a tourbillon 5.

Le tourbillon 5 comprend une cage 6 portant notamment une roue d'échappement 8, un balancier 9 et un spiral 10, ces deux derniers éléments constituant un oscillateur mécanique. Le pignon de la roue d'échappement engrène avec une couronne dentée 11 solidaire de la masse oscillante.The vortex 5 comprises a cage 6 including an escape wheel 8, a balance 9 and a spiral 10, the latter two elements constituting a mechanical oscillator. The pinion of the escape wheel meshes with a ring gear 11 integral with the oscillating mass.

Une roue dentée intermédiaire 12, ou couronne, est solidaire de la cage du tourbillon, de manière conventionnelle, celle-ci étant destinée à être reliée à un rouage de finissage pour transmettre de l'énergie depuis l'organe moteur jusqu'à l'oscillateur mécanique, par l'intermédiaire de la roue d'échappement.An intermediate gearwheel 12, or ring gear, is integral with the vortex casing in a conventional manner, the latter being intended to be connected to a finishing gear train for transmitting energy from the motor unit to the gearbox. mechanical oscillator, via the escape wheel.

Le mouvement horloger selon la présente invention comporte en outre un engrenage différentiel 14 d'axe X1 comprenant un porte-satellite 15, monté rotatif en référence à la platine 4 et, comprenant un pont 16 portant un satellite 17, définissant une première entrée de l'engrenage différentiel. Le porte-satellite comprend également une denture 18, définissant une seconde entrée, ainsi qu'une roue de sortie 19, montée sur le porte-satellite de manière à en être libre, pour définir une sortie de l'engrenage différentiel. La roue de sortie 19 engrène avec la roue intermédiaire 12 du tourbillon 5.The watch movement according to the present invention further comprises a differential gear 14 of axis X1 comprising a planet carrier 15 rotatably mounted with reference to plate 4 and comprising a bridge 16 carrying a satellite 17 defining a first input of the planet. differential gear. The carrier also comprises a toothing 18, defining a second input, and an output wheel 19, mounted on the carrier free so as to define an output of the differential gear. The output wheel 19 meshes with the intermediate wheel 12 of the vortex 5.

Une roue 21 reliée cinématiquement à l'organe moteur est agencée en prise avec le satellite 17 pour lui en transmettre la force.A wheel 21 kinematically connected to the drive member is arranged in engagement with the satellite 17 to transmit the force thereto.

On notera qu'un renvoi inverseur 22 a été prévu sur le mode de réalisation de la figure 1, à titre illustratif non limitatif, entre le satellite 17 et le pignon 33 solidaire fixé à la roue de sortie 19, pour que cette dernière transmette la force de l'organe moteur à la roue d'échappement 8 avec le bon sens de rotation. Bien entendu, l'homme du métier ne rencontrera pas de difficulté particulière pour prévoir un tel inverseur en tout autre endroit adapté du mouvement, sans sortir du cadre de la présente invention.Note that an inverting reference 22 has been provided on the embodiment of the figure 1 , by way of nonlimiting illustration, between the satellite 17 and the pinion 33 secured to the output wheel 19, so that the latter transmits the force of the drive member to the escape wheel 8 with the correct direction of rotation. Of course, those skilled in the art will not encounter any particular difficulty in providing such an inverter anywhere else suitable for the movement, without departing from the scope of the present invention.

La figure 2, qui représente une vue en coupe simplifiée d'une variante de réalisation selon la ligne II-II de la figure 1, permet de mieux apprécier le fonctionnement de l'engrenage différentiel 14.The figure 2 , which represents a simplified sectional view of an alternative embodiment along line II-II of FIG. figure 1 , makes it possible to better appreciate the operation of the differential gearing 14.

Il apparaît de la figure 2 qu'un tube creux 24 est logé fixe dans la platine 4 du mouvement, suivant l'axe X1.It appears from the figure 2 a hollow tube 24 is fixedly housed in the plate 4 of the movement along the axis X1.

Un renvoi 25 est logé à l'intérieur du tube creux 24 en étant libre de tourner par rapport au tube. Celui-ci comporte une première roue 26, proche de la platine, reliée cinématiquement à l'organe moteur et la roue 21, côté ponts, agencée en prise avec une première roue 30 du satellite 17. Le satellite comprend une seconde roue 32 agencée en prise avec un pignon 33 libre sur le porte-satellite 15, donc de la roue de sortie 19.A return 25 is housed inside the hollow tube 24 being free to rotate relative to the tube. This comprises a first wheel 26, close to the plate, kinematically connected to the drive member and the wheel 21, bridge side, arranged in engagement with a first wheel 30 of the satellite 17. The satellite comprises a second wheel 32 arranged in taken with a free pinion 33 on the planet carrier 15, thus of the output wheel 19.

De ce fait, le satellite 17 constitue une première entrée de l'engrenage différentiel permettant de retransmettre la force de l'organe moteur à la roue d'échappement 8 via la roue intermédiaire 12.As a result, the satellite 17 constitutes a first input of the differential gear for retransmitting the force of the drive member to the escape wheel 8 via the intermediate wheel 12.

On notera que la variante de la figure 2 prévoit de relier directement le satellite 17 au pignon 33, contrairement au mode de réalisation de la figure 1 selon lequel la seconde roue 32 du satellite 17 est agencée en prise avec une première roue d'un renvoi inverseur 22 dont la seconde roue est en prise avec le pignon 33, pour inverser le sens de rotation de ce dernier. Dans le cas de la figure 2, un renvoi inverseur (non illustré) produisant le même effet est disposé dans la chaîne cinématique entre la roue 26 et l'organe moteur. Bien entendu, l'utilisation d'un renvoi simple, c'est-à-dire ne comportant qu'une seule roue, est également possible sans sortir du cadre de la présente invention.It will be noted that the variant of figure 2 plans to directly connect the satellite 17 to the pinion 33, contrary to the embodiment of the figure 1 wherein the second wheel 32 of the satellite 17 is arranged in engagement with a first wheel of an inverting gear 22 whose second wheel is in engagement with the pinion 33, to reverse the direction of rotation of the latter. In the case of figure 2 , an inverting gear (not shown) producing the same effect is disposed in the drive train between the wheel 26 and the drive member. Of course, the use of a simple return, that is to say having only one wheel, is also possible without departing from the scope of the present invention.

Du côté de la platine 4, un mobile 35 est monté libre en rotation sur l'arbre creux 24 tout en étant fixé rigidement au bâti 2 de la masse oscillante, dans le but de réaliser le montage de cette dernière en rotation en référence à la platine 4.On the side of the plate 4, a mobile 35 is rotatably mounted on the hollow shaft 24 while being fixed rigidly to the frame 2 of the oscillating mass, for the purpose of carrying out the mounting of the latter in rotation with reference to the platinum 4.

Le mobile 35 présente un premier pignon 36 permettant de transmettre l'énergie générée par les mouvements de la masse oscillante à l'organe moteur, tel un ressort de barillet, par l'intermédiaire d'un train de remontage conventionnel (non représenté).The mobile 35 has a first pinion 36 for transmitting the energy generated by the movements of the oscillating mass to the drive member, such as a mainspring, via a conventional winding train (not shown).

Le mobile 35 présente un second pignon 38 agencé en prise avec une première roue 40 d'un renvoi 41 monté rotatif sur un pont 42 solidaire du tube creux 24. Le renvoi 41 comporte une seconde roue 43 engrenant avec la denture 18 du porte-satellite 15 qui constitue, comme mentionné plus haut, la seconde entrée de l'engrenage différentiel.The mobile 35 has a second gear 38 arranged in engagement with a first wheel 40 of a gear 41 rotatably mounted on a bridge 42 integral with the hollow tube 24. The gear 41 comprises a second wheel 43 meshing with the toothing 18 of the carrier Which is, as mentioned above, the second input of the differential gear.

Le rapport d'engrenage entre le second pignon 38 et la denture 18 du porte-satellite est avantageusement choisi de telle manière que, lorsque la roue d'échappement est fixe, le porte-satellite présente à chaque instant un déplacement angulaire identique à celui de ladite masse oscillante. Dans le même temps, le satellite 17 est entraîné en rotation par la rotation du pont 16 du porte-satellite ce qui fait rouler sa première roue 30 sur la roue 21 et sa seconde roue 32 sur le pignon 33 sans qu'aucune transmission de force n'intervienne.The gear ratio between the second pinion 38 and the toothing 18 of the planet carrier is advantageously chosen in such a way that, when the escape wheel is stationary, the planet carrier has at each moment an angular displacement identical to that of said oscillating weight. At the same time, the satellite 17 is rotated by the rotation of the bridge 16 of the planet carrier which rolls its first wheel 30 on the wheel 21 and its second wheel 32 on the pinion 33 without any transmission of force. intervenes.

Grâce à ces caractéristiques, le seul déplacement de la masse oscillante ne transmet aucun couple à la roue d'échappement qui ne peut, par conséquent, fournir des impulsions à l'oscillateur mécanique qu'à partir de la force qui lui est transmise depuis la première entrée de l'engrenage différentiel, soit le satellite 17.Thanks to these characteristics, the only movement of the oscillating mass does not transmit any torque to the escape wheel, which can not, therefore, provide pulses to the mechanical oscillator that from the force transmitted to it since the first input of the differential gear, the satellite 17.

Le tourbillon ne sera pas décrit plus en détail dans le présent exposé dans la mesure où il ne contribue pas directement à l'invention. Il est en effet possible de mettre en oeuvre le mouvement horloger à remontage automatique selon la présente invention, sans difficulté particulière, avec tout autre type d'échappement connu.The vortex will not be described in more detail in this disclosure as it does not contribute directly to the invention. It is indeed possible to implement the self-winding watch movement according to the present invention, without particular difficulty, with any other known type of escapement.

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 la structure spécifiquement illustrée et décrite pour l'engrenage différentiel plan. On notera par exemple qu'un engrenage différentiel sphérique pourra être mis en oeuvre sans difficulté particulière sur la base de l'enseignement ci-dessus.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 characteristics which have just been described, such as, for example, the structure specifically illustrated and described for the planar differential gearing. It will be noted for example that a spherical differential gearing can be implemented without particular difficulty on the basis of the teaching above.

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 mouvement horloger à remontage automatique dont la masse oscillante porte l'échappement, sans sortir du cadre de la présente invention. On notera par exemple que l'homme du métier pourra adapter ce qui vient d'être décrit pour disposer un nombre de mobiles constitutifs du rouage de finissage adapté à ses propres besoins, ou pour disposer, par exemple une indication de la seconde sur la masse oscillante.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 a self-winding watch movement whose oscillating mass carries the escapement without departing from the scope of the present invention. . It will be noted, for example, that the person skilled in the art will be able to adapt the above described to have a number of mobiles constituting the finishing gear train adapted to his own needs, or to have, for example, an indication of the second on the mass. oscillating.
