Description

Domaine techniqueTechnical area

La présente invention concerne une roue, pour dispositif inverseur destiné à équiper un mouvement horloger, comportant une planche présentant un premier rayon R1 et munie d'une denture périphérique.The present invention relates to a wheel for an inverter device intended to equip a watch movement, comprising a board having a first radius R1 and provided with a peripheral toothing.

La présente invention concerne également un procédé de fabrication d'une telle roue, ainsi que des dispositifs inverseurs mettant en oeuvre de telles roues et destinés à équiper un mouvement horloger, préférablement du type à remontage automatique.The present invention also relates to a method of manufacturing such a wheel, as well as inverter devices using such wheels and intended to equip a watch movement, preferably self-winding type.

Etat de la techniqueState of the art

Des roues de ce type sont déjà couramment utilisées dans des mouvements horlogers à remontage automatique, notamment dans des dispositifs inverseurs disposés dans le train de remontage automatique du ressort de barillet. A titre d'exemple, 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 , décrit et illustre différentes réalisations de telles roues, aux pages 180 et suivantes, ainsi que le fonctionnement des dispositifs inverseurs correspondants.Wheels of this type are already commonly used in self-winding watch movements, especially in reversing devices arranged in the winding automatic winding of the mainspring. For example, the book entitled " Clockwork Theory ", by C.-A.Reymondin et al., Edited by the Federation of Technical Schools (Switzerland), ISBN 2-940025-10-X , describes and illustrates different embodiments of such wheels, on pages 180 and following, as well as the operation of the corresponding inverter devices.

On distingue principalement deux types de roues, à savoir certaines destinées à coopérer avec un organe inverseur suivant une direction axiale, et d'autres destinées à coopérer avec un organe inverseur dans le plan général de la roue. Dans le premier cas, les roues présentent des structures généralement plus simples que dans le second cas, mais les dispositifs correspondant présentent un encombrement supérieur. Cependant, lorsque la coopération entre la roue et l'organe inverseur intervient dans le plan général de la roue, il est nécessaire d'usiner des crans ou des becs dans la roue, notamment par fraisage, ce qui peut s'avérer complexe et coûteux. Cet inconvénient est d'autant plus gênant lorsque deux roues sont nécessaires pour réaliser un dispositif inverseur double dans un même mouvement horloger.There are mainly two types of wheels, namely some intended to cooperate with an inverter member in an axial direction, and others intended to cooperate with an inverter member in the general plane of the wheel. In the first case, the wheels have generally simpler structures than in the second case, but the corresponding devices have a larger footprint. However, when the cooperation between the wheel and the inverter member occurs in the general plane of the wheel, it is necessary to machine notches or beaks in the wheel, especially by milling, which can be complex and expensive . This disadvantage is even more troublesome when two wheels are needed to make a double inverter device in the same watch movement.

Par ailleurs, on notera que ces dispositifs ne sont généralement pas mis en oeuvre dans le train de remontage manuel dans lequel est généralement utilisé un mécanisme de débrayage, pour éviter la rotation de la tige de remontoir lorsque le barillet est entraîné à partir du mécanisme de remontage automatique.Moreover, it should be noted that these devices are generally not used in the manual winding gear in which a disengaging mechanism is generally used, to avoid the rotation of the winding stem when the barrel is driven from the mechanism of automatic winding.

Divulgation de l'inventionDisclosure of the invention

Un but principal de la présente invention est de pallier les inconvénients des dispositifs inverseurs connus de l'art antérieur, en proposant une roue pour dispositif inverseur dont la fabrication est simplifiée par rapport aux roues connues de l'art antérieur et permettant la réalisation de dispositifs inverseurs de structure simple et peu encombrante.A main object of the present invention is to overcome the disadvantages of reversing devices known from the prior art, by proposing a wheel for an inverter device whose manufacture is simplified with respect to the known wheels of the prior art and allowing the production of devices inverters of simple and compact structure.

A cet effet, la présente invention concerne plus particulièrement une roue du type mentionné plus haut, caractérisée par le fait qu'elle comporte une noyure centrale dont la périphérie présente n becs périphériques destinés à coopérer avec un organe inverseur et dont chacun est défini par l'intersection d'un trou circulaire avec la périphérie de la noyure centrale, n étant égal ou supérieur à un.For this purpose, the present invention relates more particularly to a wheel of the type mentioned above, characterized in that it comprises a central core whose periphery has n peripheral nozzles intended to cooperate with an inverter member and each of which is defined by the intersection of a circular hole with the periphery of the central core, n being equal to or greater than one.

Grâce à ces caractéristiques, la roue selon la présente invention permet une coopération avec l'organe inverseur dans son plan général, sans toutefois nécessiter la mise en oeuvre d'opérations de fraisage complexes et coûteuses pour sa réalisation.Thanks to these characteristics, the wheel according to the present invention allows a cooperation with the inverter member in its general plan, without however requiring the implementation of complex and expensive milling operations for its realization.

De manière préférée, la roue est en outre caractérisée par le fait que la noyure centrale présente une forme résultant de la combinaison d'un premier trou principal, sensiblement circulaire, central et présentant un second rayon R2, avec n trous circulaires secondaires, présentant un troisième rayon R3 inférieur au second rayon R2 et dont les centres C3 sont situés à une distance du centre C1 de la roue supérieure à R2-R3. En outre, la roue comporte alors n trous circulaires supplémentaires, présentant un quatrième rayon R4, inférieur au troisième rayon R3, chacun des n trous supplémentaires étant sécant à une portion de la périphérie de la noyure centrale définie par un seul des trous circulaires secondaires et, chacun des n trous supplémentaires ayant son centre C4 situé sur un rayon différent du rayon passant par le centre C3 du trou secondaire correspondant, à une distance de C1 supérieure au second rayon R2, de manière à définir les becs.Preferably, the wheel is further characterized in that the central core has a shape resulting from the combination of a first, substantially circular, central, first hole having a second radius R2, with n secondary circular holes, having a third radius R3 less than the second radius R2 and whose centers C3 are located at a distance from the center C1 of the upper wheel R2-R3. In addition, the wheel then has n additional circular holes, having a fourth radius R4, smaller than the third radius R3, each of the n additional holes being secant to a portion of the periphery of the central core defined by only one of the secondary circular holes and , each of the n additional holes having its center C4 located on a radius different from the radius passing through the center C3 of the hole corresponding secondary, at a distance of C1 greater than the second radius R2, so as to define the nozzles.

Ainsi, l'intégralité de l'usinage de la partie de la roue qui est destinée à coopérer avec l'organe inverseur peut être réalisée par des opérations de perçage, bien plus simples que des fraisages. Dans le cadre de la présente divulgation, il faut comprendre par perçage l'opération consistant à effectuer un trou circulaire, qui peut être borgne ou traversant, par la mise en oeuvre d'un outil de perçage exerçant une action sur le matériau à usiner dans la direction de son axe de rotation.Thus, the entire machining of the portion of the wheel which is intended to cooperate with the inverter member can be achieved by drilling operations, much simpler than milling. In the context of the present disclosure, it is necessary to understand by drilling the operation of making a circular hole, which can be blind or through, by the implementation of a drilling tool exerting an action on the material to be machined in the direction of its axis of rotation.

La présente invention concerne également un procédé de fabrication d'une telle roue comprenant les étapes consistant à se munir d'une planche présentant un premier rayon R1 et ménager une denture périphérique sur la planche, caractérisé par le fait qu'il comporte les étapes supplémentaires consistant à:

  • former une noyure centrale, dans la planche,
  • réaliser n becs, à la périphérie de la noyure centrale, destinés à coopérer avec un organe inverseur et dont chacun est défini par l'intersection d'un trou circulaire avec la périphérie de la noyure centrale, n étant égal ou supérieur à un.
The present invention also relates to a method of manufacturing such a wheel comprising the steps of providing a board having a first radius R1 and providing a peripheral toothing on the board, characterized in that it comprises the additional steps consists in:
  • form a central core, in the board,
  • producing n beaks, at the periphery of the central core, intended to cooperate with an inverter member and each of which is defined by the intersection of a circular hole with the periphery of the central core, n being equal to or greater than one.

De manière avantageuse, la noyure centrale est formée par le perçage d'un premier trou principal, sensiblement circulaire, central et présentant un second rayon R2, combiné au perçage préalable de n trous circulaires secondaires, présentant un troisième rayon R3 inférieur au second rayon R2 et dont les centres C3 sont situés à une distance du centre C1 de la roue supérieure à R2-R3. Le procédé comporte une étape supplémentaire consistant à percer n trous circulaires supplémentaires, présentant un quatrième rayon R4, inférieur au troisième rayon R3, chacun des n trous supplémentaires étant sécant à une portion de la périphérie de la noyure centrale définie par un seul des trous circulaires secondaires et, chacun des n trous supplémentaires ayant son centre C4 situé sur un rayon différent du rayon passant par le centre C3 du trou secondaire correspondant, à une distance de C1 supérieure au second rayon R2, de manière à définir les becs. De manière avantageuse, les trous supplémentaires peuvent être percés avant les autres trous.Advantageously, the central core is formed by drilling a first, substantially circular, central, first hole having a second radius R2, combined with the prior drilling of n secondary circular holes, having a third radius R3 smaller than the second radius R2. and whose centers C3 are located at a distance from the center C1 of the upper wheel to R2-R3. The method comprises an additional step of drilling n additional circular holes, having a fourth radius R4, less than the third radius R3, each of the n additional holes being secant to a portion of the periphery of the central core defined by only one of the circular holes and each of the n additional holes having its center C4 located on a radius different from the radius passing through the center C3 of the corresponding secondary hole, at a distance of C1 greater than the second radius R2, of way to define the beaks. Advantageously, the additional holes can be drilled before the other holes.

Par ailleurs, l'invention concerne également un dispositif inverseur simple, destiné à équiper un mouvement horloger, comportant des première et seconde roues dentées destinées à être respectivement agencées en prise avec des premier et second mobiles du mouvement horloger, les première et seconde roues étant coaxiales et reliées entre elles par un organe inverseur agencé pour transmettre une rotation de la première roue à la seconde roue dans un sens de rotation prédéfini et empêcher la transmission d'une rotation de la seconde roue, dans le sens de rotation prédéfini, à la première roue. Le dispositif est caractérisé par le fait que l'organe inverseur comporte deux dents, sensiblement diamétralement opposées et de formes asymétriques, et est relié mécaniquement à la première roue de manière à en être solidaire en rotation tout en étant susceptible de se déplacer entre des première et seconde positions extrêmes suivant une direction radiale, en référence à la première roue. En outre, la seconde roue répond aux caractéristiques énoncées plus haut, et comporte une planche, présentant un premier rayon R1 et munie d'une denture périphérique, ainsi qu'une noyure centrale définissant un logement pour l'organe inverseur et dont la périphérie présente n becs périphériques, destinés à coopérer avec les dents de l'organe inverseur dans le sens de rotation prédéfini, et dont chacun est défini par l'intersection de deux trous circulaires, n étant égal ou supérieur à un.Furthermore, the invention also relates to a simple inverter device, intended to equip a watch movement, comprising first and second gears intended to be respectively engaged with first and second mobiles of the watch movement, the first and second wheels being coaxial and interconnected by an inverter member arranged to transmit a rotation of the first wheel to the second wheel in a predefined direction of rotation and prevent the transmission of a rotation of the second wheel, in the predefined direction of rotation, to the first wheel. The device is characterized in that the reversing member comprises two teeth, substantially diametrically opposed and of asymmetric shapes, and is mechanically connected to the first wheel so as to be integral in rotation while being able to move between first and second extreme positions in a radial direction, with reference to the first wheel. In addition, the second wheel meets the characteristics stated above, and comprises a board, having a first radius R1 and provided with a peripheral toothing, and a central core defining a housing for the inverter member and whose periphery has n peripheral nozzles, intended to cooperate with the teeth of the inverter member in the predefined direction of rotation, and each of which is defined by the intersection of two circular holes, n being equal to or greater than one.

L'invention concerne également un dispositif inverseur double, destiné à équiper un mouvement horloger, comportant des première et seconde roues dentées destinées à être entraînées simultanément dans des sens de rotation opposés par un mécanisme du mouvement horloger, les première et seconde roues étant toutes deux coaxiales à un organe denté de sortie, destiné à être relié cinématiquement à un premier mobile du mouvement horloger, et reliées mécaniquement à l'organe de sortie par des premier et second organes inverseurs respectifs, agencés pour transmettre à l'organe de sortie une rotation de l'une ou l'autre roue dans un seul et même sens de rotation prédéfini et empêcher la transmission d'une rotation de l'organe de sortie, dans le sens de rotation prédéfini, à l'une ou l'autre des roues. Ce dispositif est caractérisé par le fait que chacun des organes inverseurs comporte deux dents, sensiblement diamétralement opposées et de formes asymétriques, et est relié mécaniquement à l'organe de sortie de manière à en être solidaire en rotation tout en étant susceptible de se déplacer entre des première et seconde positions extrêmes suivant une direction radiale. Le dispositif est en outre caractérisé par le fait que chacune des première et seconde roues comporte une planche, présentant un premier rayon R10, respectivement R100, et munie d'une denture périphérique, ainsi qu'une noyure centrale définissant un logement pour l'organe inverseur correspondant et dont la périphérie présente n becs périphériques, destinés à coopérer avec les dents de l'organe inverseur correspondant dans le sens de rotation prédéfini, et dont chacun est défini par l'intersection d'un trou circulaire avec la périphérie de la noyure centrale, n étant égal ou supérieur à un.The invention also relates to a dual inverter device, intended to equip a watch movement, comprising first and second gears intended to be driven simultaneously in opposite directions of rotation by a mechanism of the watch movement, the first and second wheels being both coaxial with a toothed output member, intended to be kinematically connected to a first mobile of the watch movement, and mechanically connected to the output member by first and second respective inverter members, arranged to transmit to the output member a rotation one or the other wheel in one and the same direction of rotation and prevent the transmission a rotation of the output member, in the predefined direction of rotation, to one or other of the wheels. This device is characterized in that each of the inverter members comprises two teeth, substantially diametrically opposed and of asymmetric shapes, and is mechanically connected to the output member so as to be integral in rotation while being able to move between first and second extreme positions in a radial direction. The device is further characterized in that each of the first and second wheels comprises a board, having a first radius R10, respectively R100, and provided with a peripheral toothing, and a central core defining a housing for the body corresponding inverter and whose periphery has n peripheral nozzles, intended to cooperate with the teeth of the corresponding inverter member in the predefined direction of rotation, and each of which is defined by the intersection of a circular hole with the periphery of the core central, n being equal to or greater than one.

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

La figure 1 illustre, de manière schématique, le procédé de fabrication d'une roue 1 selon un mode de réalisation préféré de la présente invention, une telle roue étant destinée à équiper un dispositif inverseur, notamment pour être intégrée dans un train de remontage d'un mouvement horloger du type à remontage automatique.The figure 1 illustrates, schematically, the method of manufacturing a wheel 1 according to a preferred embodiment of the present invention, such a wheel being intended to equip an inverter device, in particular to be integrated into a winding train of a movement watchmaker of the self-winding type.

Le procédé de fabrication comprend les étapes qui suivent, après s'être muni d'une planche de roue 2, de centre C1, présentant un premier rayon R1 et dans laquelle est ménagée une denture périphérique 3.The manufacturing method comprises the following steps, after being equipped with a wheel board 2, C1 center, having a first radius R1 and in which is formed a peripheral toothing 3.

Une noyure centrale 5 est réalisée, préférablement par un perçage d'un second rayon R2. Une pluralité de trous circulaires secondaires 6 est réalisée par des opérations de perçage, avec un troisième rayon R3, inférieur au second rayon R2. De manière avantageuse, les centres C3 des trous secondaires 6 sont situés à une distance du centre C1 de la planche 2 supérieure à R2-R3. Ainsi, les trous secondaires coupent la périphérie de la noyure centrale 5.A central core 5 is made, preferably by drilling a second radius R2. A plurality of secondary circular holes 6 is made by drilling operations, with a third radius R3, smaller than the second radius R2. Advantageously, the centers C3 of the secondary holes 6 are situated at a distance from the center C1 of the plate 2 greater than R2-R3. Thus, the secondary holes intersect the periphery of the central core 5.

On peut prévoir que n trous secondaires sont percés, n étant supérieur ou égal à un.It can be expected that n secondary holes are drilled, n being greater than or equal to one.

Une opération supplémentaire consiste à percer n trous circulaires supplémentaires 8 présentant un quatrième rayon R4, inférieur au troisième rayon R3. Chacun des trous supplémentaires 8 est sécant à une portion de la périphérie de la noyure centrale 5 définie par un seul des trous secondaires 6, en ayant son centre C4 situé sur un rayon différent du rayon passant par le centre C3 du trou secondaire 6 correspondant, à une distance de C1 supérieure au second rayon R2.An additional operation is to drill n additional circular holes 8 having a fourth radius R4, less than the third radius R3. Each of the additional holes 8 is secant to a portion of the periphery of the central core 5 defined by only one of secondary holes 6, having its center C4 located on a radius different from the radius passing through the center C3 of the corresponding secondary hole 6 at a distance of C1 greater than the second radius R2.

L'intersection de chaque trou secondaire 8 avec le trou supplémentaire 6 correspondant définit un bec 10 destiné à coopérer avec un organe inverseur, comme cela ressortira de la description détaillée des figures suivantes.The intersection of each secondary hole 8 with the corresponding additional hole 6 defines a spout 10 intended to cooperate with an inverter member, as will be apparent from the detailed description of the following figures.

Les trous secondaires et supplémentaires peuvent indifféremment être borgnes ou traversants, sans sortir du cadre de la présente invention.The secondary and additional holes can indifferently be blind or through, without departing from the scope of the present invention.

On notera que la chronologie de mise en oeuvre des étapes qui viennent d'être décrites est susceptible de varier en fonction des emplacements et rayons des différents trous à percer. II est en effet plus aisé de percer un trou lorsque l'emplacement de son centre n'est pas vide de matière.It will be noted that the chronology of implementation of the steps which have just been described may vary according to the locations and radii of the various holes to be drilled. It is indeed easier to drill a hole when the location of its center is not empty of material.

II ressort de la description du procédé ci-dessus qu'il n'est pas nécessaire, comme c'est le cas selon l'art antérieur, de mettre en oeuvre des opérations d'usinage complexes et coûteuses. En effet, de simples opérations de perçage conventionnel sont suffisantes pour fabriquer la roue selon la présente invention.It follows from the description of the above method that it is not necessary, as is the case in the prior art, to implement complex and expensive machining operations. Indeed, simple conventional drilling operations are sufficient to manufacture the wheel according to the present invention.

Les figures 2, 3 et 4 illustrent tout ou partie d'un dispositif inverseur simple selon un premier mode de réalisation préféré de la présente invention.The Figures 2, 3 and 4 illustrate all or part of a simple inverter device according to a first preferred embodiment of the present invention.

La figure 2 représente, dans une vue en perspective simplifiée, des constituants du dispositif inverseur simple selon ce premier mode de réalisation.The figure 2 represents, in a simplified perspective view, constituents of the simple inverter device according to this first embodiment.

Le dispositif inverseur comporte une première roue dentée 20 présentant une ouverture centrale (non visible) dans laquelle est logé, solidaire, un organe central de liaison 21.The reversing device comprises a first gear wheel 20 having a central opening (not visible) in which is housed, secured, a central connecting member 21.

Ce dernier comprend un canon 22, de forme générale cylindrique et, dans lequel sont ménagés deux méplats 24 parallèles.The latter comprises a barrel 22, of cylindrical general shape and in which are formed two flats 24 parallel.

Un organe inverseur 25, comprenant deux dents 26 de forme asymétrique, est engagé sur le canon 22 par l'intermédiaire d'une ouverture centrale 27. Chaque dent présente un côté avant (dans le sens de rotation efficace) sensiblement radial et un côté arrière présentant une portion courte sensiblement tangentielle et suivie d'une pente douce, elle-même suivie d'une portion longue assurant la jonction jusqu'à la dent suivante, de forme sensiblement circulaire.An inverter member 25, comprising two teeth 26 of asymmetrical shape, is engaged on the barrel 22 via a central opening 27. Each tooth has a front side (in the direction of rotation effective) substantially radial and a rear side having a substantially tangential short portion and followed by a gentle slope, itself followed a long portion ensuring the junction until the next tooth, of substantially circular shape.

L'ouverture centrale présente une forme sensiblement oblongue avec une largeur légèrement supérieure à la distance séparant les deux méplats 24 et une longueur supérieure au diamètre du canon 22.The central opening has a substantially oblong shape with a width slightly greater than the distance separating the two flats 24 and a length greater than the diameter of the barrel 22.

II ressort de la figure 2 que l'organe inverseur est relié à l'organe de liaison 21, donc à la première roue 20, de telle manière qu'il est solidaire en rotation de la première roue, tandis qu'il est susceptible de se déplacer suivant une direction sensiblement radiale par rapport à l'axe de celle-ci.It appears from figure 2 that the reversing member is connected to the connecting member 21, thus to the first wheel 20, so that it is integral in rotation with the first wheel, while it is capable of moving in a direction substantially radial with respect to the axis thereof.

La figure 3 représente une vue en coupe du dispositif inverseur alors que les constituants décrits en relation avec la figure 2 sont assemblés à un arbre central 30 destiné au montage du dispositif sur le bâti (non représenté) d'un mouvement horloger.The figure 3 represents a sectional view of the inverter device while the constituents described in connection with the figure 2 are assembled to a central shaft 30 for mounting the device on the frame (not shown) of a watch movement.

En outre, une seconde roue 32 est assemblée aux autres constituants, en étant coaxiale à la première roue 20 et à l'arbre 30.In addition, a second wheel 32 is assembled to the other components, being coaxial with the first wheel 20 and the shaft 30.

La seconde roue 32 est obtenue par le procédé de fabrication décrit plus haut, en relation avec la figure 1.The second wheel 32 is obtained by the manufacturing method described above, in connection with the figure 1 .

La figure 4 illustre, dans une vue en perspective simplifiée, comment la seconde roue 32, qui comprend ici sept becs 10, coopère avec l'organe inverseur 25 et comment le dispositif inverseur peut avantageusement être mis en oeuvre dans un mouvement horloger.The figure 4 illustrates, in a simplified perspective view, how the second wheel 32, which here comprises seven nozzles 10, cooperates with the inverter member 25 and how the inverter device can advantageously be implemented in a watch movement.

On constate, sur la figure 4, que l'organe inverseur 25 est logé dans la noyure centrale 5 de la seconde roue et présente des dimensions telles que ses dents 26 sont susceptibles de coopérer avec les becs 10 de cette dernière.On the figure 4 , that the inverter member 25 is housed in the central core 5 of the second wheel and has dimensions such that its teeth 26 are capable of cooperating with the nozzles 10 of the latter.

Plus précisément, il ressort que la forme asymétrique des dents 26 a pour conséquence qu'une dent peut coopérer avec un bec dans un seul sens de rotation relatif entre l'organe inverseur et la seconde roue, à savoir lorsque l'organe inverseur est entraîné en rotation dans le sens anti-horaire sur la représentation de la figure 4. On note en outre que la coopération entre l'organe inverseur et la seconde roue ne fait intervenir qu'une seule dent à la fois.More specifically, it appears that the asymmetrical shape of the teeth 26 has the consequence that a tooth can cooperate with a nose in a single direction of relative rotation between the inverter member and the second wheel, namely when the inverter member is driven. in counter-clockwise rotation on the representation of the figure 4 . Note also that the cooperation between the inverter member and the second wheel involves only one tooth at a time.

Dans le mode de réalisation représenté sur la figure 4, le dispositif inverseur simple est mis en oeuvre dans un train de remontage manuel d'un mouvement horloger du type à remontage automatique, c'est-à-dire entre la tige de remontoir (non représentée) et le barillet 40.In the embodiment shown on the figure 4 , the simple inverter device is implemented in a manual winding train of a watch movement of the self-winding type, that is to say between the winding stem (not shown) and the barrel 40.

La tige de remontoir est agencée de manière conventionnelle pour entraîner un pignon coulant (non représenté) destiné à entraîner en rotation un pignon de remontoir 42, par l'intermédiaire de dentures Breguet 43.The winding stem is conventionally arranged to drive a sliding pinion (not shown) intended to rotate a winding pinion 42 by means of Breguet teeth 43.

Le pignon de remontoir engrène avec la première roue 20 du dispositif inverseur par une denture supplémentaire 44. Le pignon de remontoir 42 est uniquement entraîné en rotation lorsque la tige de remontoir est tournée dans le sens de rotation horaire (en l'observant depuis l'extérieur vers l'intérieur), du fait de l'orientation conventionnelle des dentures Breguet.The winding pinion meshes with the first wheel 20 of the reversing device by an additional toothing 44. The winding pinion 42 is only rotated when the winding stem is rotated in the clockwise direction (observing it from the outside inwards), because of the conventional orientation of the Breguet teeth.

La première roue 20 est alors entraînée dans le sens de rotation anti-horaire et induit de ce fait une rotation de l'organe inverseur 25 dans le même sens de rotation.The first wheel 20 is then driven in the counterclockwise direction of rotation and thereby causes rotation of the inverter member 25 in the same direction of rotation.

On se trouve alors dans la configuration de la figure 4, dans laquelle une dent 26 coopère avec un bec 10 de la seconde roue 32 pour entraîner cette dernière en rotation, dans le même sens.We are then in the configuration of the figure 4 , in which a tooth 26 cooperates with a spout 10 of the second wheel 32 to drive the latter in rotation, in the same direction.

Le tambour du barillet 40 est ainsi entraîné en rotation dans le sens horaire pour recharger son ressort (non visible).The barrel of the barrel 40 is thus rotated in the clockwise direction to reload its spring (not visible).

On notera, par ailleurs, qu'un cliquet 45 a été prévu pour coopérer avec la première roue 20. Le cliquet 45 comporte une planche 46 munie d'une dent périphérique 47 unique agencée en prise avec la denture de la première roue 20. La planche 46 présente un méplat 48 sur une portion de sa périphérie, contre lequel un ressort 49 est disposé en appui, de manière à maintenir la planche 46 dans sa position angulaire telle que représentée sur la figure 4. Ainsi, à chaque pas de la première roue 20 dans le sens anti-horaire, la planche 46 tourne d'un pas dans le sens horaire et reprend immédiatement sa position initiale sous l'effet de l'action du ressort 49. On obtient par conséquent, lorsque la tige de remontoir est tournée dans le sens horaire, un effet de cliquet similaire à celui produit par un cliquet de rochet conventionnel.Note, moreover, that a pawl 45 has been provided to cooperate with the first wheel 20. The pawl 45 comprises a plate 46 provided with a single peripheral tooth 47 arranged in engagement with the toothing of the first wheel 20. The board 46 has a flat portion 48 on a portion of its periphery, against which a spring 49 is disposed in abutment, so as to maintain the board 46 in its angular position as shown in FIG. figure 4 . Thus, at each step of the first wheel 20 in the counterclockwise direction, the board 46 rotates one step clockwise and immediately resumes its initial position under the effect of the action of the spring 49. It is obtained by therefore, when the winding stem is turned clockwise, a ratcheting effect similar to that produced by a conventional ratchet pawl.

A l'inverse, lorsque la tige de remontoir est tournée dans le sens anti-horaire, le glissement des dentures Breguet produit un effet de cliquet similaire qui n'est présent que sur certains calibres horlogers connus, soit du type à remontage manuel, soit du type à remontage automatique mais dans lesquels un dispositif de débrayage n'est pas prévu dans le train de remontage, comme c'est le cas par exemple du calibre 7750 commercialisé par la société suisse ETA S.A. Manufacture Horlogère Suisse. Cet effet de cliquet, lorsqu'il est présent dans les deux sens de rotation de la tige de remontoir, procure une impression de qualité au porteur de la montre correspondante lorsqu'il la remonte manuellement.Conversely, when the winding stem is rotated counter-clockwise, the sliding of the Breguet teeth produces a similar ratchet effect which is present only on certain known watch calibers, either of the manual winding type or the self-winding type but in which a disengagement device is not provided in the winding train, as is the case for example caliber 7750 marketed by the Swiss company ETA SA Manufacture Horlogère Switzerland. This ratchet effect, when present in both directions of rotation of the winding stem, provides an impression of quality to the wearer of the corresponding watch when it goes back manually.

De plus, le cliquet 45 assure avantageusement la fonction supplémentaire de cliquet anti-retour pour le tambour de barillet. En effet, le diamètre de la planche 46 de l'un des côtés de la dent unique 47 est égal au diamètre qu'elle présente au niveau de la dent, empêchant ainsi toute rotation de la première roue 20 dans le sens de rotation horaire. Une telle caractéristique, combinée notamment avec l'emplacement du cliquet 45, permet d'améliorer le rendement du remontage automatique étant donné que le mécanisme de remontage automatique n'a pas besoin de surmonter la force du cliquet 45 pour remonter le ressort de barillet, contrairement aux mécanismes de l'art antérieur, grâce à l'agencement du dispositif inverseur.In addition, the pawl 45 advantageously provides the additional function of non-return pawl for the barrel drum. Indeed, the diameter of the board 46 of one side of the single tooth 47 is equal to the diameter it has at the tooth, thus preventing any rotation of the first wheel 20 in the clockwise direction of rotation. Such a characteristic, combined in particular with the location of the pawl 45, improves the efficiency of the automatic winding since the automatic winding mechanism does not need to overcome the force of the pawl 45 to raise the mainspring, unlike the mechanisms of the prior art, thanks to the arrangement of the inverter device.

En effet, lorsque le remontage manuel n'est pas utilisé, le ressort de barillet peut être rechargé à partir du mécanisme de remontage automatique. Dans ce cas, le tambour du barillet 40 est entraîné par ce dernier dans le sens de rotation horaire.Indeed, when manual winding is not used, the barrel spring can be recharged from the automatic winding mechanism. In this case, the barrel of the barrel 40 is driven by the latter in the direction of clockwise rotation.

Ce mouvement de rotation du tambour de barillet entraîne la rotation de la seconde roue 32 du dispositif inverseur dans le sens anti-horaire. Dans ce cas, toutefois, les becs 10 entrent au contact des dents 26 de l'organe inverseur par leur côté qui n'est pas efficace, avec le côté incliné des dents. Ainsi, non seulement la seconde roue 32 n'entraîne pas l'organe inverseur 25 en rotation, mais le repousse de telle manière qu'il se déplace sur le canon 22. Si la seconde roue 32 tourne pendant un certain temps, l'organe inverseur effectue des mouvements de va-et-vient entre ses deux positions extrêmes, ses dents étant alternativement repoussées par les côtés arrières des becs 10.This rotational movement of the barrel drum causes rotation of the second wheel 32 of the reversing device in the counter-clockwise direction. In this case, however, the nozzles 10 come into contact with the teeth 26 of the inverter member by their side which is not effective, with the inclined side of the teeth. Thus, not only the second wheel 32 does not cause the inverter member 25 to rotate, but the push back so that it is moves on the barrel 22. If the second wheel 32 rotates for a certain time, the reversing organ moves back and forth between its two extreme positions, its teeth being alternately pushed back by the rear sides of the spouts 10.

Ainsi, le mouvement de rotation de la seconde roue 32 dans le sens de rotation anti-horaire n'est pas transmis à la première roue 20 qui reste immobile.Thus, the rotational movement of the second wheel 32 in the anti-clockwise direction of rotation is not transmitted to the first wheel 20 which remains stationary.

On constate donc que le dispositif inverseur selon la présente invention remplit la même fonction que les dispositifs de débrayage de l'art antérieur, de manière plus efficace puisque l'effet d'inversion est instantané contrairement au débrayage.It is therefore found that the inverter device according to the present invention performs the same function as the disengagement devices of the prior art, more effectively since the inversion effect is instantaneous unlike the clutch.

Les figures 5 à 7 illustrent un dispositif inverseur double selon un second mode de réalisation préféré de la présente invention, mettant en oeuvre deux roues du type dont le procédé de fabrication a été décrit plus haut, en relation avec la figure 1.The Figures 5 to 7 illustrate a dual inverter device according to a second preferred embodiment of the present invention, implementing two wheels of the type whose manufacturing method has been described above, in connection with the figure 1 .

La figure 5 représente une vue en perspective simplifiée, partiellement en transparence, de cet inverseur double.The figure 5 represents a simplified perspective view, partially in transparency, of this double inverter.

Celui-ci comporte un arbre central 50 sur lequel sont montées, libres en rotation, deux roues 51 et 52 du type dont le procédé de fabrication a été décrit plus haut, en relation avec la figure 1, c'est-à-dire comprenant chacune une noyure centrale dans la périphérie de laquelle sont ménagés des becs 53, 54This comprises a central shaft 50 on which are mounted, free in rotation, two wheels 51 and 52 of the type whose manufacturing process has been described above, in connection with the figure 1 , that is to say each comprising a central core in the periphery of which are formed beaks 53, 54

Les roues 51, 52 sont superposées et adjacentes, des premier et second organes inverseurs 56, 57 étant logés dans leurs noyures centrales respectives. Chacun des organes inverseurs est similaire à celui décrit précédemment, en relation avec la figure 2, c'est-à-dire qu'il comporte deux dents 58, 59 destinées à coopérer avec les becs 53 ou 54 de la roue à laquelle il est associé.The wheels 51, 52 are superposed and adjacent, first and second inverter members 56, 57 being housed in their respective central openings. Each of the reversing members is similar to that described above, in connection with the figure 2 , that is to say it has two teeth 58, 59 for cooperating with the nozzles 53 or 54 of the wheel with which it is associated.

L'arbre central 50 présente une section munie de deux méplats 60 sensiblement parallèles entre eux et destinés à définir des surfaces de guidage pour des ouvertures centrales 62 ménagées dans les organes inverseurs. Ainsi, ces derniers sont susceptibles de se déplacer suivant une direction radiale en référence à l'arbre central 50, de même que décrit plus haut, en relation avec le premier mode de réalisation.The central shaft 50 has a section provided with two flats 60 substantially parallel to each other and intended to define guide surfaces for central openings 62 formed in the inverter members. Thus, they are likely to move next a radial direction with reference to the central shaft 50, as described above, in connection with the first embodiment.

Il ressort de la figure 5 que les deux organes inverseurs 56, 57 et les roues 51, 52 sont agencés de telle manière que chaque roue entraîne son organe inverseur uniquement lorsqu'elle tourne dans le sens de rotation anti-horaire.It appears from figure 5 that the two inverter members 56, 57 and the wheels 51, 52 are arranged in such a way that each wheel drives its reversing member only when it rotates in the counterclockwise direction of rotation.

A l'inverse, lorsque les roues 51 et 52 sont entraînées dans le sens de rotation horaire, les becs 53, 54 glissent sur les dents 58, 59 sans entraîner les organes inverseurs en rotation, mais en les forçant à effectuer un va-et-vient entre leurs deux positions extrêmes le long des méplats 60.Conversely, when the wheels 51 and 52 are driven in the clockwise direction, the nozzles 53, 54 slide on the teeth 58, 59 without causing the rotating inverter members, but forcing them to perform a va-and -between their two extreme positions along flats 60.

On notera en relation avec la figure 5 que les deux ensembles roue - organe inverseur sont disposés dans le même sens.We will note in relation to the figure 5 that the two sets of wheel-inverter members are arranged in the same direction.

La figure 6 représente une vue en coupe simplifiée du dispositif inverseur de la figure 5, selon la ligne de coupe VI-VI de la figure 5, de laquelle il ressort que l'arbre central 50 comprend deux éléments constitutifs, à savoir un arbre principal 64 et un organe de guidage 65 dans lequel sont ménagés les méplats 60.The figure 6 represents a simplified sectional view of the inverter device of the figure 5 , according to the section line VI-VI of the figure 5 from which it emerges that the central shaft 50 comprises two constituent elements, namely a main shaft 64 and a guide member 65 in which are formed the flats 60.

L'arbre principal est destiné à rendre le dispositif inverseur solidaire d'un élément de bâti du mouvement horloger auquel il est destiné au moyen d'un alésage central 66. De plus, il comporte un pignon 67 destiné à former un organe de sortie du dispositif inverseur comme cela ressortira plus clairement de la description détaillée de la figure 7.The main shaft is intended to make the inverter device integral with a frame member of the watch movement to which it is intended by means of a central bore 66. In addition, it comprises a pinion 67 intended to form an output member of the reversing device as will become clearer from the detailed description of the figure 7 .

Bien entendu, il est possible de prévoir que l'arbre principal porte directement des pivots pour le montage sur le bâti du mouvement horloger en lieu et place de l'alésage central 66 sans sortir du cadre de l'invention.Of course, it is possible to provide that the main shaft directly carries pivots for mounting on the frame of the watch movement in place of the central bore 66 without departing from the scope of the invention.

On notera que l'assemblage du dispositif inverseur selon la présente invention est très simple. En effet, il suffit de mettre en place la première roue 51 sur l'organe de guidage 65, puis les deux organes inverseurs 56 et 57, puis la seconde roue 52, avant d'insérer l'arbre principal 64 dans un trou 68 adapté de l'organe de guidage, pour rendre ces deux éléments solidaires l'un de l'autre.Note that the assembly of the inverter device according to the present invention is very simple. Indeed, it is sufficient to set up the first wheel 51 on the guide member 65, then the two inverter members 56 and 57, then the second wheel 52, before inserting the main shaft 64 in a hole 68 adapted of the guide member, to make these two elements integral with one another.

Le fonctionnement de ce dispositif inverseur double va être exposé à présent, en relation avec la figure 7 qui représente une vue de face simplifiée, partiellement en transparence, d'un exemple de mise en oeuvre de l'inverseur double de la figure 5 dans un mouvement horloger.The operation of this dual inverter device will now be exposed, in connection with the figure 7 which represents a simplified front view, partially in transparency, of an example of implementation of the double inverter of the figure 5 in a watch movement.

Les roues 51, 52 sont destinées à être reliées à un dispositif de remontage automatique, pour être entraînées en rotation à partir des mouvements d'une masse oscillante (non visible pour plus de clarté).The wheels 51, 52 are intended to be connected to an automatic winding device, to be rotated from the movements of an oscillating mass (not visible for clarity).

Plus précisément, la première roue 51 engrène directement avec une roue de remontage automatique 70, elle-même reliée directement ou indirectement à une masse oscillante.More precisely, the first wheel 51 meshes directly with an automatic winding wheel 70, itself connected directly or indirectly to an oscillating mass.

La seconde roue 52 engrène avec la roue 70 par l'intermédiaire d'un renvoi 71, pour tourner dans le sens de rotation opposé à celui de la première roue à chaque instant.The second wheel 52 meshes with the wheel 70 via a return 71, to rotate in the direction of rotation opposite that of the first wheel at each moment.

L'organe de sortie du dispositif inverseur double, soit le pignon 67 de l'arbre principal 64, engrène avec un premier mobile 72 d'un train de remontage automatique, le premier mobile engrenant avec un second mobile 73, lui-même en prise avec le tambour du barillet 40.The output member of the double inverter device, namely the pinion 67 of the main shaft 64, meshes with a first mobile 72 of an automatic winding train, the first mobile meshing with a second mobile 73, itself engaged. with the barrel drum 40.

Comme on l'a relevé plus haut, une rotation de l'une ou l'autre des roues 51 , 52 dans le sens anti-horaire entraîne une rotation de l'organe inverseur correspondant dans le même sens de rotation, tandis qu'une rotation de roue dans le sens horaire n'entraîne pas l'organe inverseur.As noted above, a rotation of one or the other of the wheels 51, 52 in the counterclockwise direction causes rotation of the corresponding inverter member in the same direction of rotation, while wheel rotation in the clockwise direction does not cause the reversing member.

Lorsque l'un des organes inverseurs est entraîné en rotation (donc forcément dans le sens anti-horaire dans le mode de réalisation représenté) il induit un mouvement identique de l'organe de sortie du dispositif, à savoir le pignon 67.When one of the inverter members is rotated (thus necessarily in the counterclockwise direction in the embodiment shown) it induces an identical movement of the output member of the device, namely the pinion 67.

Ainsi, lorsque la roue 70 est entraînée dans le sens de rotation horaire, par la masse oscillante, elle induit une rotation dans le même sens de la seconde roue 52 et une rotation anti-horaire de la première roue 51. Dans ce cas, les becs 54 de la seconde roue glissent sur les dents 59 de l'organe inverseur 57 correspondant, tandis que l'un des becs 53 de la première roue accroche l'une des dents 58 de l'organe inverseur 56 correspondant pour l'entraîner en rotation.Thus, when the wheel 70 is driven in the direction of clockwise rotation, by the oscillating mass, it induces a rotation in the same direction of the second wheel 52 and a counter-clockwise rotation of the first wheel 51. In this case, the nibs 54 of the second wheel slide on the teeth 59 of the corresponding inverter member 57, while one of the nozzles 53 of the first wheel hooks one of the teeth 58 of the corresponding inverter member 56 to drive it into position. rotation.

Par conséquent, une rotation horaire de la roue 70 entraîne une rotation anti-horaire du pignon 67 de sortie du dispositif inverseur double selon la présente invention, par l'intermédiaire de la première roue 51.Therefore, a clockwise rotation of the wheel 70 causes a counter-clockwise rotation of the output pinion 67 of the dual inverter device according to the present invention, through the first wheel 51.

A l'inverse, lorsque la roue 70 est entraînée dans le sens de rotation anti-horaire, par la masse oscillante, elle induit une rotation dans le même sens de la seconde roue 52 et une rotation horaire de la première roue 51. Dans ce cas, l'un des becs 54 de la seconde roue accroche l'une des dents 59 de l'organe inverseur 57 correspondant pour l'entraîner en rotation, tandis que les becs 53 de la première roue glissent sur les dents 58 de l'organe inverseur 56 correspondant.Conversely, when the wheel 70 is driven in the anti-clockwise direction by the oscillating mass, it induces a rotation in the same direction of the second wheel 52 and a clockwise rotation of the first wheel 51. in this case, one of the nozzles 54 of the second wheel hooks one of the teeth 59 of the corresponding inverter member 57 to drive it in rotation, while the nozzles 53 of the first wheel slide on the teeth 58 of the corresponding inverter member 56.

Par conséquent, une rotation anti-horaire de la roue 70 entraîne également une rotation anti-horaire du pignon 67 de sortie du dispositif inverseur double selon la présente invention, par l'intermédiaire de la seconde roue 52.Therefore, a counter-clockwise rotation of the wheel 70 also causes a counterclockwise rotation of the output gearwheel 67 of the dual inverter device according to the present invention, via the second wheel 52.

Par conséquent, le dispositif inverseur double selon la présente invention permet d'exploiter les rotations de la masse oscillante, quel que soit son sens de rotation, pour recharger le ressort de barillet.Therefore, the dual inverter device according to the present invention allows to exploit the rotations of the oscillating mass, whatever its direction of rotation, to reload the mainspring.

On notera en outre que le dispositif inverseur double selon la présente invention permet également d'empêcher toute rotation du tambour de barillet dans le sens d'une décharge du ressort de barillet. En effet, dans ce cas, les deux roues 51 et 52 sont entraînées dans le même sens de rotation et tendent à entraîner la roue 70 dans des sens de rotation opposés du fait de la présence du renvoi 71, ce qui a pour conséquence de les bloquer. Ainsi, il n'est pas nécessaire de prévoir un cliquet pour le tambour de barillet.It will be further noted that the dual inverter device according to the present invention also makes it possible to prevent any rotation of the barrel drum in the direction of a discharge of the mainspring. Indeed, in this case, the two wheels 51 and 52 are driven in the same direction of rotation and tend to drive the wheel 70 in opposite directions of rotation due to the presence of the return 71, which has the consequence of the block. Thus, it is not necessary to provide a ratchet for the barrel drum.

On notera que la structure très simple de ce dispositif permet avantageusement d'en limiter l'encombrement en référence aux dispositifs de ce type connus de l'art antérieur. En outre, le nombre réduit de ses constituants rend également sa fabrication avantageuse par rapport aux dispositifs connus, permettant d'en réduire les coûts de fabrication de manière importante.It will be noted that the very simple structure of this device advantageously makes it possible to limit its bulk with reference to devices of this type known from the prior art. In addition, the reduced number of its constituents also makes its manufacturing advantageous compared to known devices, to reduce the manufacturing costs significantly.

La description qui précède s'attache à décrire des modes de réalisation particuliers 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 le nombre de trous prévus dans les roues illustrées et décrites, le nombre de dents des organes inverseurs, ou encore les sens de rotation mentionnés.The foregoing description attempts to describe particular embodiments 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 number of holes provided in the wheels illustrated and described, the number of teeth of the inverter members, or the directions of rotation mentioned.

On notera que la roue selon la présente invention peut simplement être réalisée en ménageant la noyure centrale, sensiblement circulaire, puis en perçant une seule série de trous supplémentaires, à sa périphérie, pour définir les becs destinés à coopérer avec un organe inverseur. Même si une telle solution est moins efficace que celle du mode de réalisation préféré, elle peut s'avérer suffisante.It should be noted that the wheel according to the present invention can simply be made by providing the central, substantially circular core, then by drilling a single series of additional holes, at its periphery, to define the nozzles intended to cooperate with an inverter member. Even if such a solution is less effective than that of the preferred embodiment, it may be sufficient.

On notera que les deux dispositifs inverseurs décrits, un simple et un double, peuvent être utilisés indépendamment l'un de l'autre ou en combinaison dans un même mouvement horloger, voire en relation avec un autre mécanisme horloger que le remontage, notamment une complication faisant appel à un seul sens de rotation d'une roue.Those skilled in the art will not encounter any particular difficulty in adapting the content of the present disclosure to their own needs and implementing a wheel, an inverter device or a watch movement that is different from the embodiments described here, but in which the wheel has a central core whose periphery has n peripheral nozzles intended to cooperate with an inverter member and each of which is defined by the intersection of two circular holes, n being equal to or greater than two, without departing from the scope of the present invention. Note that the two reversing devices described, a single and a double, can be used independently of one another or in combination in the same watch movement, or in connection with another watch mechanism that reassembly, including a complication using only one direction of rotation of a wheel.
