Description

Domaine techniqueTechnical area

La présente invention concerne un mécanisme horloger de conversion permettant la conversion d'un mouvement rotatif d'amplitude et de sens quelconque en un mouvement rotatif unidirectionnel.The present invention relates to a conversion clock mechanism for converting a rotary motion of any amplitude and direction into a unidirectional rotary motion.

Etat de la techniqueState of the art

Dans un mouvement d'horlogerie à remontage automatique, le remontage du ressort moteur ou ressort de barillet s'effectue au moyen d'une masse qui oscille sous l'effet des mouvements du porteur de la montre. La force générée par les oscillations de la masse est communiquée au rochet de remontage du ressort moteur par un rouage réducteur. Certains mécanismes de remontage automatique, dits « bidirectionnels », comprennent, entre la masse oscillante et le rouage réducteur, un dispositif appelé « inverseur » permettant au rouage réducteur de tourner dans le sens entraînant le remontage du ressort moteur quel que soit le sens de rotation de la masse oscillante. Un type particulièrement avantageux de ce dispositif inverseur, en termes de simplicité, d'efficacité et d'encombrement, est connu sous le nom de « système Pellaton » et décrit dans le brevet DE882227 . Le système Pellaton comprend une came solidaire de la masse oscillante, une bascule coopérant avec la came par l'intermédiaire de deux galets, et deux cliquets montés sur la bascule. Les becs respectifs des cliquets sont maintenus en contact, par un ressort agissant entre les cliquets, avec la denture d'une roue à dents de loup reliée au rochet de remontage par l'intermédiaire du rouage réducteur. Sous l'effet des mouvements oscillants de la bascule, causés par les rotations de la came, ces deux cliquets font alternativement avancer la roue à dents de loup. Des variantes de ce mécanisme ont été décrites dans le brevet US3846973 et dans les demandes de brevet JP 2003130967 et JP 2003279666 In a self-winding watch movement, the winding of the mainspring or mainspring is effected by means of a mass which oscillates under the effect of the movements of the wearer of the watch. The force generated by the oscillations of the mass is communicated to the winding ratchet of the mainspring by a gear reducer. Some automatic winding mechanisms, called "bidirectional", comprise, between the oscillating weight and the gear train, a device called "inverter" allowing the gear train to rotate in the direction causing the winding of the mainspring irrespective of the direction of rotation. of the oscillating mass. A particularly advantageous type of this inverter device, in terms of simplicity, efficiency and bulk, is known as the "Pellaton system" and described in US Pat. DE882227 . The Pellaton system comprises a cam secured to the oscillating mass, a rocker cooperating with the cam via two rollers, and two pawls mounted on the rocker. The respective beaks of the pawls are held in contact, by a spring acting between the pawls, with the toothing of a wolf-tooth wheel connected to the winding ratchet by means of the gear wheel. Under the effect of oscillating movements of the rocker, caused by the rotations of the cam, these two pawls alternately advance the wolf wheel. Variations of this mechanism have been described in the patent US3846973 and in patent applications JP 2003130967 and JP 2003279666

Cette solution présente notamment l'avantage par rapport à l'art antérieur d'offrir de meilleures performances, notamment un rendement accru ainsi qu'un angle dit de freinage et angle dit mort, autrement appelé chemin perdu, réduits, le tout contribuant à une meilleure efficacité du mécanisme. D'autre part, une réduction des forces et couples à l'entrée pour les mêmes paramètres à la sortie conduit à une réduction des contraintes et un accroissement de la longévité du système et du mouvement horloger qui en est équipé.This solution has the particular advantage over the prior art of offering better performance, in particular efficiency increased and a so-called braking angle and angle called dead, otherwise called lost path, reduced, all contributing to a better efficiency of the mechanism. On the other hand, a reduction in the input forces and torques for the same parameters at the output leads to a reduction of the stresses and an increase in the longevity of the system and the watch movement which is equipped with it.

Exemple(s) de mode de réalisation de l'inventionExample (s) of embodiment of the invention

La figure 1 représente un mécanisme de conversion destiné à une application horlogère, selon un mode de réalisation. En particulier, le mécanisme comprend un premier mobile 3 entraînable selon un mouvement rotatif quelconque (par exemple bidirectionnel), un second mobile 5, et un organe de transmission 4 coopérant avec le premier et le second mobile 3, 5. Le premier mobile 3 comprend une planche 31 pivotant autour d'un axe de rotation 33 et un organe de guidage 32. L'organe de guidage 32 est configuré pour entraîner l'organe de transmission 4 de manière excentrée par rapport à l'axe 33. Le second mobile 5 comporte une planche 52, ou roue dentée, entraînant un organe d'embrayage 51. Remarquons que le mouvement rotatif du premier mobile 3 peut être unidirectionnel ou bidirectionnel.The figure 1 represents a conversion mechanism for a watch application, according to one embodiment. In particular, the mechanism comprises a first mobile 3 drivable according to any rotary movement (for example bidirectional), a second mobile 5, and a transmission member 4 cooperating with the first and the second mobile 3, 5. The first mobile 3 comprises a board 31 pivoting about an axis of rotation 33 and a guide member 32. The guide member 32 is configured to drive the transmission member 4 eccentrically relative to the axis 33. The second mobile 5 comprises a board 52, or toothed wheel, driving a clutch member 51. Note that the rotary movement of the first mobile 3 can be unidirectional or bidirectional.

Le premier mobile 3, la planche 31 et l'organe de guidage 32 peuvent être constitués d'une seule pièce.The first mobile 3, the board 31 and the guide member 32 may consist of a single piece.

Dans l'exemple de la figure 1, le mécanisme de conversion est compris dans un mécanisme de remontage automatique d'une montre comprenant une masse oscillante. Dans la figure, seule une suspension 1 à roulement à billes est représentée. Un mobile intermédiaire menant 2 est en prise avec un pignon (pas représenté) solidaire de la suspension 1. Le mobile intermédiaire menant 2 est également en prise avec la planche 31 du premier mobile 3 (ou mobile menant) de sorte que le mouvement de rotation de la masse oscillante est transmis au premier mobile 3 par le biais du mobile intermédiaire menant 2. Le mécanisme de remontage automatique comprend également un mobile intermédiaire mené 6 en prise avec la planche 52 du second mobile 5 (ou mobile mené) et avec un rochet de barillet 7. Alternativement, le premier mobile 3 peut être monté coaxial avec l'axe de pivotement de la masse oscillante, dans quel cas le mobile intermédiaire menant 2 n'est pas requis.In the example of the figure 1 , the conversion mechanism is included in an automatic winding mechanism of a watch comprising an oscillating weight. In the figure, only a ball bearing suspension 1 is shown. An intermediate mobile leading 2 is engaged with a pinion (not shown) integral with the suspension 1. The intermediate driving mobile 2 is also engaged with the board 31 of the first mobile 3 (or moving mobile) so that the rotational movement of the oscillating mass is transmitted to the first mobile 3 through the intermediate mobile leading 2. The automatic winding mechanism also comprises an intermediate mobile led 6 engaged with the board 52 of the second mobile 5 (or driven mobile) and with a barrel ratchet 7. Alternatively, the first mobile 3 can be mounted coaxial with the pivot axis of the oscillating mass, in which case the intermediate driving mobile 2 is not required.

Dans cette configuration, l'organe de transmission 4 coopère avec le second mobile 5 par le biais de l'organe d'embrayage 51 de façon intermittente, de manière à entraîner le second mobile 5 selon un mouvement rotatif unidirectionnel. En particulier, la masse oscillante entraîne, par le biais du mobile intermédiaire menant 2, le premier mobile 3 en rotation dans les deux sens selon la rotation de la masse oscillante.In this configuration, the transmission member 4 cooperates with the second mobile 5 through the clutch member 51 intermittently, so as to drive the second mobile 5 in a unidirectional rotary motion. In particular, the oscillating mass drives, through the intermediate driving mobile 2, the first mobile 3 in rotation in both directions according to the rotation of the oscillating mass.

De la sorte, la masse oscillante pivotant librement dans les deux sens entraîne le rochet de barillet 7, par le biais du second mobile 5 et du mobile intermédiaire mené 6, dans un seul sens afin d'armer le ressort de barillet (non représenté).In this way, the oscillating mass pivoting freely in both directions drives the barrel ratchet 7, via the second mobile 5 and the driven intermediate wheel 6, in a single direction to arm the barrel spring (not shown). .

Selon une forme d'exécution, l'organe de transmission 4 comprend deux leviers 42 s'étendant depuis organe de guidage 32 et est terminé par un organe de blocage 40. Lorsque l'organe de transmission 4 est entraîné par le premier mobile 3, l'organe de blocage 40 de chacun des leviers 42 coopère alternativement avec l'organe d'embrayage 51 lorsque l'organe de transmission 4 coopère avec le second mobile 5.According to one embodiment, the transmission member 4 comprises two levers 42 extending from the guiding member 32 and is terminated by a locking member 40. When the transmission member 4 is driven by the first mobile 3, the locking member 40 of each of the levers 42 cooperates alternately with the clutch member 51 when the transmission member 4 cooperates with the second mobile unit 5.

Dans un mode de réalisation, l'organe de blocage 40 comprend un élément mobile 44 coopérant par coincement, blocage ou friction avec l'organe d'embrayage 51 lorsque l'organe de transmission 4 coopère avec le second mobile 5.In one embodiment, the locking member 40 comprises a mobile element 44 cooperating by jamming, locking or friction with the clutch member 51 when the transmission member 4 cooperates with the second mobile 5.

La figure 2 montre une vue isolée de l'organe de transmission 4 et l'organe d'embrayage 51.The figure 2 shows an isolated view of the transmission member 4 and the clutch member 51.

Selon une forme d'exécution, l'organe d'embrayage 51 comporte une bague de roulement 53 pourvue d'un chemin de roulement 54. L'organe de blocage 40 prend la forme d'une portion d'un roulement à bille comportant deux logements 45, chaque logement étant configuré comme une portion de cage. L'élément mobile comprend une bille 44 maintenue dans le logement 45. Le logement 45 possède un plan incliné 401 de sorte que, lorsque l'organe de blocage 40 coopère avec le chemin de roulement 54, la bille 44 se coince entre le chemin de roulement 54 et le plan incliné 401 du logement 45. Le plan incliné 401 peut être rectiligne ou curviligne. L'organe de blocage 40 peut ainsi entraîner le second mobile 5. Dans les figures 1 et 2, un des organes de blocage 40 est représenté "fermé", c'est-à-dire avec une cage de support 43 enfermant les logements 45 et les billes 44. L'autre organe de blocage 40 est montré "ouvert", c'est-à-dire sans la cage de support 43 permettant de voit les logements 45 et les billes 44.According to one embodiment, the clutch member 51 comprises a bearing ring 53 provided with a raceway 54. The locking member 40 takes the form of a portion of a ball bearing comprising two housings 45, each housing being configured as a cage portion. The movable element comprises a ball 44 held in the housing 45. The housing 45 has an inclined plane 401 so that, when the locking member 40 cooperates with the raceway 54, the ball 44 gets stuck between the path bearing 54 and the inclined plane 401 of the housing 45. The inclined plane 401 may be rectilinear or curvilinear. The locking member 40 can thus drive the second mobile 5. In the figures 1 and 2 , one of the locking members 40 is shown "closed", that is to say with a support cage 43 enclosing the housings 45 and the balls 44. The other locking member 40 is shown "open", c ' that is to say without the support cage 43 allowing to see the housings 45 and the balls 44.

On admettra d'autres arrangements de l'organe de blocage 40 dans le cadre de l'invention. Par exemple, l'organe de blocage 40 peut comprendre un nombre différent de logements 45 et de billes 44. L'élément mobile 44 peut également comprendre des rouleaux ou tout autre élément approprié au lieu de billes. On notera également qu'une seule bille 44 ou un seul cylindre de friction (ou rouleau) par organe de blocage 40 peut suffire si l'élément mobile 44 est complété par un rochet à friction (par exemple monté sur un bâti de montre) qui retient le second mobile 5 dans le sens de dégrènement.Other arrangements of the locking member 40 will be allowed within the scope of the invention. For example, the locking member 40 may comprise a different number of housings 45 and balls 44. The movable member 44 may also include rollers or other suitable element instead of balls. Note also that a single ball 44 or a single friction cylinder (or roll) by locking member 40 may be sufficient if the movable member 44 is completed by a friction ratchet (for example mounted on a watch frame) which retains the second mobile 5 in the direction of disengagement.

L'organe de transmission 4 et de l'organe de guidage 32 sont configurés de sorte que l'organe de blocage 40 de chacun des leviers 42 coopère avec l'organe d'embrayage 51 de manière intermittente et alternée entraînant le second mobile 5 dans un seul sens et d'évitant une rotation du second mobile 5 dans le sens contraire.The transmission member 4 and the guide member 32 are configured so that the locking member 40 of each of the levers 42 cooperates with the clutch member 51 intermittently and alternately driving the second mobile 5 in one direction and avoiding a rotation of the second mobile 5 in the opposite direction.

La planche 52 de second mobile 5 peut être en prise avec un pignon (non représenté) coaxial avec la bague de roulement 53 (tel qu'illustré à la figure 1) ou être montée pivotante sur le même axe 55 que celui de la bague de roulement 53.The plate 52 of the second mobile 5 may be engaged with a pinion (not shown) coaxial with the bearing ring 53 (as illustrated in FIG. figure 1 ) or be pivotally mounted on the same axis 55 as that of the bearing ring 53.

Selon mode d'exécution, l'organe de guidage comprend un élément d'articulation 32 solidaire de la planche 31 de premier mobile 3 et excentré par rapport l'axe de rotation 33. L'élément d'articulation 32 permet de guider une bascule 41 sur laquelle sont fixés les leviers 42. Par exemple, l'élément d'articulation peut comprendre une portée (ou un pivot) 32 solidaire au premier mobile 3 et excentré par rapport à l'axe de rotation 33 du premier mobile. La bascule 41 peut comprendre un alésage 46 s'engageant librement autour du pivot 32. Dans cette configuration, chacun des leviers fonctionnent de façon semblable à une bielle articulée à partir du pivot 32.According to embodiment, the guide member comprises a hinge member 32 integral with the board 31 of the first moving part 3 and eccentric with respect to the axis of rotation 33. The hinge member 32 serves to guide a rocker 41 on which are fixed the levers 42. For example, the hinge member may comprise a bearing (or pivot) 32 secured to the first mobile 3 and eccentric with respect to the axis of rotation 33 of the first mobile. The latch 41 may comprise a bore 46 freely engaging around the pivot 32. In this configuration, each of the levers operate in a manner similar to a rod articulated from the pivot 32.

Un palier 47 peut être inséré entre le pivot 32 et l'alésage circulaire 46 de manière à diminuer les frottements entre la bascule 41 et le pivot 32.A bearing 47 can be inserted between the pivot 32 and the circular bore 46 so as to reduce the friction between the latch 41 and the pivot 32.

Dans une variante, les leviers 42 comprennent une portion flexible 409 (voir figure 2) pouvant jouer un rôle de pivot virtuel reliant la bascule 41 à l'organe d'embrayage 40.In a variant, the levers 42 comprise a flexible portion 409 (see FIG. figure 2 ) can play a role of virtual pivot connecting the latch 41 to the clutch member 40.

Selon une variante non représentée, l'élément d'articulation comprend une came montée concentrique avec l'axe 33 et dont le rayon est variable par rapport à l'axe 33. La bascule 41 peut être guidée par la came. Par came à rayon variable, on entend une came quelconque de n'importe quelle géométrie, comme par exemple un excentrique, un coeur à spirale d'Archimède, une came de Reuleux, un polygone, etc.According to a variant not shown, the hinge member comprises a cam mounted concentrically with the axis 33 and whose radius is variable relative to the axis 33. The latch 41 may be guided by the cam. Variable-radius cam means any cam of any geometry, such as for example an eccentric, an Archimedes spiral core, a Reuleux cam, a polygon, etc.

La figure 3 illustre le mécanisme de conversion selon une variante, dans laquelle l'organe de transmission 4 comprend un seul levier 42 s'étendant depuis la bascule 41 et est terminé par l'organe de blocage 40. Lorsque l'organe de transmission 4 est entraîné par le premier mobile 3, l'unique organe de blocage 40 coopère de façon intermittente avec l'organe d'embrayage 51 et entraîne le second mobile 5. Un élément fixe de blocage 60 permet d'éviter que le second mobile 5 pivote dans le sens opposé à celui dans lequel il est entraîné par l'organe de transmission 4 lorsque l'organe de blocage 40 n'est pas en coopération avec l'organe d'embrayage 51. Dans l'exemple de la figure 3, l'élément fixe de blocage 60 comporte deux logements 45, chacun comprenant une bille 45, comme illustré dans les figures 1 et 2. L'élément fixe de blocage 60 peut être fixé à un bâti de la montre ou peut être monté sur une seconde bascule qui est fixe pendant que la première bascule est mobile.The figure 3 illustrates the conversion mechanism according to a variant, wherein the transmission member 4 comprises a single lever 42 extending from the latch 41 and is terminated by the locking member 40. When the transmission member 4 is driven by the first mobile 3, the single locking member 40 cooperates intermittently with the clutch member 51 and drives the second mobile 5. A fixed locking member 60 prevents the second mobile 5 pivots in the opposite direction to that in which it is driven by the transmission member 4 when the locking member 40 is not in cooperation with the clutch member 51. In the example of the figure 3 , the fixed locking member 60 comprises two housings 45, each comprising a ball 45, as illustrated in FIGS. figures 1 and 2 . The fixed locking member 60 may be attached to a frame of the watch or may be mounted on a second latch which is stationary while the first latch is movable.

La figure 4 montre le mécanisme de conversion encore selon un autre mode de réalisation. La figure 5 montre une vue en perspective et la figure 6 montre une vue du dessus de l'organe de transmission 4 et du second mobile 5 selon la configuration de la figure 4. L'organe de transmission 4 comprend deux bascules 41 comportant chacune un levier 42. Les deux bascules 41 sont montées coaxiales sur un élément d'articulation 32 (pivot) commun excentré par rapport à l'axe 33 de rotation du premier mobile 3. L'élément d'articulation 32 guide les deux bascules et leur levier 42 respectif selon un mouvement semblable à celui d'une bielle de sorte que l'organe de blocage 40 de chacun des leviers 42 coopère alternativement avec l'organe d'embrayage 51 lorsque l'organe de transmission 4 est entraîné par le premier mobile 3. Les deux bascules peuvent être rendues solidaires l'une de l'autre, par exemple à l'aide des doigts entraineurs 34.The figure 4 shows the conversion mechanism again according to another embodiment. The figure 5 shows a perspective view and the figure 6 shows a view from above of the transmission member 4 and the second mobile 5 according to the configuration of the figure 4 . The transmission member 4 comprises two latches 41 each having a lever 42. The two latches 41 are mounted coaxially on a joint member 32 (pivot) common eccentric with respect to the axis 33 of rotation of the first mobile 3. L hinge member 32 guides the two latches and their respective lever 42 in a movement similar to that of a connecting rod so that the locking member 40 of each of the levers 42 cooperates alternately with the clutch member 51 when the transmission member 4 is driven by the first mobile 3. The two latches can be made integral with each other, for example with the help of the fingers 34.

Dans la configuration des figures 4 et 5, l'organe de blocage 40 comprend une bascule 403 elle-même montée pivotante sur un pivot 402 à l'extrémité de chaque levier 42 et sur l'axe 55 de la bague de roulement 53. Dans cette configuration, le mouvement des leviers 42 entrainés par le premier mobile 3 fait pivoter l'organe de blocage 40 de sorte à ce que chacun des deux organes de blocage 40 coopère alternativement et entraîne le second mobile 5.In the configuration of Figures 4 and 5 , the locking member 40 comprises a latch 403 itself pivotally mounted on a pivot 402 at the end of each lever 42 and on the axis 55 of the bearing ring 53. In this configuration, the movement of the levers 42 driven by the first mobile 3 rotates the locking member 40 so that each of the two locking members 40 cooperates alternately and drives the second mobile 5.

La figure 7 illustre une variante du mécanisme de conversion des figures 4 et 5 comprenant une seule bascule 41 comportant un levier 42. Le mécanisme de conversion comporte également un élément fixe de blocage 60 configuré comme dans l'exemple de la figure 3.The figure 7 illustrates a variant of the conversion mechanism of Figures 4 and 5 comprising a single latch 41 having a lever 42. The conversion mechanism also comprises a fixed locking element 60 configured as in the example of FIG. figure 3 .

Les figures 8 à 10 montrent le fonctionnement du mécanisme de conversion selon la configuration des figures 4 à 6. En particulier, la figure 8 montre le mécanisme de conversion dans une position initiale. La figure 9 montre le mécanisme de conversion dans une position initiale. La figure 9 montre le mécanisme de conversion lorsque l'élément d'articulation 32, guidé par l'axe 33, est pivoté à 90° dans le sens antihoraire par rapport à la position initiale. Dans ce cas, les leviers 42 pivote une bascule 403 dans le sens antihoraire forçant les billes 44 à se loger dans la partie étroite du logement 45 et se coincer entre le plan incliné du logement 401, de sorte que l'organe de blocage 40 coopère avec l'organe d'embrayage 51 par arc-boutement et l'entraînant selon un mouvement rotatif antihoraire. L'autre bascule 403' pivote dans le sens horaire de sorte que les billes 44 se trouvent dans la partie large du logement 45 et peuvent librement rouler dans le logement 45. Dans les figures 8 à 10, le sens de rotation des organes entraînants (l'axe 33 et les organes de blocage 40) est indiqué par les flèches pleines et le sens de rotation des organes entraînés (l'élément d'articulation 32 et l'organe d'embrayage 51) est indiqué par les flèches en pointillés.The Figures 8 to 10 show the operation of the conversion mechanism according to the configuration of Figures 4 to 6 . In particular, figure 8 shows the conversion mechanism in an initial position. The figure 9 shows the conversion mechanism in an initial position. The figure 9 shows the conversion mechanism when the hinge member 32, guided by the axis 33, is rotated 90 ° counterclockwise with respect to the initial position. In this case, the levers 42 pivots a latch 403 counterclockwise forcing the balls 44 to be housed in the narrow part of the housing 45 and jam between the inclined plane of the housing 401, so that the locking member 40 cooperates with the clutch member 51 by bracing and driving in a counterclockwise rotational movement. The other latch 403 'pivots clockwise so that the balls 44 are in the wide part of the housing 45 and can freely roll in the housing 45. Figures 8 to 10 , the direction of rotation of the driving members (the axis 33 and the locking members 40) is indicated by the solid arrows and the direction of rotation of the driven members (the hinge member 32 and the clutch member 51 ) is indicated by the dashed arrows.

La figure 10 montre le mécanisme de conversion lorsque l'élément d'articulation 32 est pivoté à 270° dans le sens antihoraire par rapport à la position initiale. Dans cette configuration, la bascule 403 pivote dans le sens horaire et les billes 44 roulent librement dans la partie large du logement 45. La bascule 403' pivote dans le sens antihoraire forçant les billes 44 à se loger dans la partie étroite du logement 45 de sorte que l'organe de blocage 40 entraîne l'organe d'embrayage 51 selon un mouvement rotatif antihoraire.The figure 10 shows the conversion mechanism when the hinge member 32 is rotated 270 ° counterclockwise from the initial position. In this configuration, the latch 403 pivots clockwise and the balls 44 roll freely in the wide part of the housing 45. The latch 403 'pivots counterclockwise forcing the balls 44 to be housed in the narrow part of the housing 45 of so that the locking member 40 drives the clutch member 51 in a counterclockwise rotational movement.

La figure 11 représente le mécanisme de conversion selon un autre mode de réalisation et la figure 12 montre une vue en perspective et la figure 13 montre une vue du dessus de l'organe de transmission 4 et du second mobile 5 selon la configuration de la figure 11. L'organe de transmission 4 comprend une bascule 41 comportant deux leviers 42. La bascule 41 est guidée par un pivot 32 solidaire au premier mobile 3 et excentré par rapport à l'axe de rotation 33 du premier mobile 3, comme dans la configuration de la figure 1.The figure 11 represents the conversion mechanism according to another embodiment and the figure 12 shows a perspective view and the figure 13 shows a view from above of the transmission member 4 and the second mobile 5 according to the configuration of the figure 11 . The transmission member 4 comprises a latch 41 comprising two levers 42. The latch 41 is guided by a pivot 32 integral with the first mobile 3 and eccentric with respect to the axis of rotation 33 of the first mobile 3, as in the configuration of FIG. the figure 1 .

L'organe de blocage 40 comprend deux roulements à billes unidirectionnels 43, 43', chacun des roulements étant guidé en pivotement sur un pivot 402 à l'extrémité d'un levier 42. Chacun des roulements 43, 43' comprend une bague extérieure coaxiale avec une bague intérieure et une cage. La cage comportant des logements possédant un plan incliné (les bagues, la cage et les logements ne sont pas visible sur les figures 11 à 13). L'accouplement entre les bagues extérieure et intérieure du roulement est réalisé dans un seul sens de rotation du roulement, lorsque les billes se bloquent par coincement entre la bague extérieure et les parois des logements. Dans le cas où le second mobile 5 est solidaire du second mobile 5, par exemple par l'intermédiaire de l'axe 55 de second mobile, le second mobile 5 sera entraîné en rotation par l'un des deux roulements 43, 43' tournant dans un sens (par exemple dans le sens antihoraire, tel qu'indiqué par les flèches dans les figures 11 à 13) et sera en roulement libre avec l'autre roulements 43, 43' tournant dans le sens inverse.The locking member 40 comprises two unidirectional ball bearings 43, 43 ', each of the bearings being pivotally guided on a pivot 402 at the end of a lever 42. Each of the bearings 43, 43' comprises a coaxial outer ring with an inner ring and a cage. The cage having dwellings having an inclined plane (the rings, the cage and the housings are not visible on the Figures 11 to 13 ). The coupling between the outer and inner rings of the bearing is made in a single direction of rotation of the bearing, when the balls are jammed by wedging between the outer ring and the housing walls. In the case where the second mobile 5 is secured to the second mobile 5, for example via the axis 55 of the second mobile, the second mobile 5 will be rotated by one of the two bearings 43, 43 'rotating in one direction (for example, counterclockwise, as indicated by the arrows in the Figures 11 to 13 ) and will be in free rotation with the other bearings 43, 43 'rotating in the opposite direction.

La figure 14 représente le mécanisme de conversion selon un autre mode de réalisation dans lequel l'organe d'embrayage 51 comprend un disque 57 pivotant concentriquement avec l'axe 55 d'un pignon 52' de second mobile 5, le pignon 52' étant destiné à engrener avec la planche 52 de second mobile 5. L'organe de transmission 4 comprend deux bascules 41, chacune comportant un levier 42. Les deux bascules 41 sont montées chacune sur un pivot 32excentré par rapport à l'axe 33 de rotation du premier mobile (pas représenté sur la figure 14). Chacun des leviers 42 est terminé par un support d'élément de blocage 404 comportant un élément de blocage (excentriques de blocage) 406 ayant un rayon variable. L'excentrique de blocage est guidé par une cheville 407. La configuration de l'organe de transmission 4 est telle que les supports d'élément de blocage 404 sont arrangés de chaque côté du disque 57. Lors de l'entraînement de l'organe de transmission 4 par le premier mobile 3, les excentriques de blocage 406 viennent en contact avec la tranche 57' du disque 57 alternativement avec la tranche 57' du disque 57 de sorte que, selon le sens d'entraînement des leviers 42, chacun des excentriques de blocage 406 pivote et se coince contre le disque 57 par arc-boutement. Le second mobile 5 est ainsi entraîné dans une seule direction. Les cames 33 des bascules sont idéalement excentrées entre elles, avec un déphasage entre leurs centres respectifs par rapport au centre du pivot 32 allant de 0° à 180°.The figure 14 represents the conversion mechanism according to another embodiment in which the clutch member 51 comprises a disc 57 pivotally concentric with the axis 55 of a pinion 52 'of second mobile 5, the pinion 52' being intended to mesh with the plate 52 of second mobile 5. The transmission member 4 comprises two latches 41, each having a lever 42. The two latches 41 are each mounted on a pivot 32excentré relative to the axis 33 of rotation of the first mobile ( not represented on the figure 14 ). Each of the levers 42 is terminated by a blocking member support 404 having a locking member (eccentric blocking) 406 having a variable radius. The locking eccentric is guided by a pin 407. The configuration of the transmission member 4 is such that the element supports of block 404 are arranged on each side of the disk 57. During the driving of the transmission member 4 by the first mobile 3, the locking eccentric 406 come into contact with the wafer 57 'of the disk 57 alternatively with the wafer 57 57 of the disk 57 so that, in the direction of driving of the levers 42, each of the locking eccentric 406 pivots and jams against the disk 57 by bracing. The second mobile 5 is thus driven in a single direction. The cams 33 of the latches are ideally eccentric to each other, with a phase shift between their respective centers relative to the center of the pivot 32 from 0 ° to 180 °.

Dans la configuration illustrée à la figure 14, chaque levier 42 possède un coude 405 flexible, autrement dit un pivot virtuel, permettant de guider les support d'élément de blocage 404 de sorte à maintenir les excentriques de blocage 406 en contact avec la tranche 57' du disque 57 quand l'organe de blocage 40 coopère avec le second mobile 5. L'excentrique de blocage 406 peut être maintenu en contact contre la tranche 57' lorsque l'organe de blocage 40 coopère avec l'organe d'embrayage 51 à l'aide d'un ressort de rappel 408, intégré à l'excentrique de blocage 406 dans cette configuration.In the configuration illustrated in figure 14 each lever 42 has a flexible bend 405, ie a virtual pivot, for guiding the blocking member supports 404 so as to maintain the locking eccentric members 406 in contact with the wafer 57 'of the disk 57 when the blocking member 40 cooperates with the second mobile 5. The locking eccentric 406 can be kept in contact against the wafer 57 'when the locking member 40 cooperates with the clutch member 51 by means of a spring 408, integrated in the locking eccentric 406 in this configuration.

La figure 15 illustre le mécanisme de conversion de la figure 11, selon une autre variante dans laquelle l'excentrique de blocage 406 est séparé du ressort de rappel 408. L'excentrique de blocage comprend une came 406 montée pivotante sur un pivot 407 .The figure 15 illustrates the conversion mechanism of the figure 11 according to another variant in which the locking eccentric 406 is separated from the return spring 408. The locking eccentric comprises a cam 406 pivotally mounted on a pivot 407.

La figure 16 montre une variante du mécanisme de conversion de la figure 15, dans laquelle l'organe de transmission 4 comprend une seule bascule 41 et un seul levier 42 comportant un excentrique de blocage 406 avec son ressort de rappel 408. Un élément fixe de blocage 60 permet d'éviter que le second mobile 5 ne pivote dans le sens opposé à celui dans lequel il est entraîné par l'organe de transmission 4 lorsque l'organe de blocage 40 n'est pas en coopération avec l'organe d'embrayage 51. Dans la configuration de la figure 16, l'élément fixe de blocage 60 comporte une came 606 pivotant autour d'un pivot 607 et maintenue en contact avec la tranche 57' du disque 57 à l'aide d'un ressort de rappel 608. La came 606 peut être montée sur un bâti d'un mouvement horloger.The figure 16 shows a variant of the conversion mechanism of the figure 15 , in which the transmission member 4 comprises a single latch 41 and a single lever 42 having a locking eccentric 406 with its return spring 408. A fixed locking member 60 prevents the second mobile 5 from pivoting in the direction opposite to that in which it is driven by the transmission member 4 when the locking member 40 is not in cooperation with the clutch member 51. In the configuration of the figure 16 the fixed locking element 60 comprises a cam 606 pivoting about a pivot 607 and kept in contact with the slice 57 'of the disk 57 by means of a return spring 608. The cam 606 can be mounted on a frame of a watch movement.

La figure 17 montre une variante du mécanisme de conversion dans laquelle ce dernier est réalisé avec un nombre réduit de pièces, notamment par la combinaison des fonctions guidage excentrique d'entrée, transmission du mouvement par un bras, fonction pivot de ce bras par élément flexible et arc-boutement contre le disque de réception dans une seule et même pièce. L'ensemble proposé pourrait toutefois comme dans certaines versions précédentes être réalisé sur deux niveaux pour séparer deux bras de bielle. L'arc-boutement est toujours réalisé sur un élément mobile en rotation autour d'un pivot virtuel, ce pivot étant de préférence un pivot fixe par rapport à un référentiel du bras le supportant. Afin d'assurer le guidage précis des deux coinceurs autour du disque d'embrayage, ceux-ci peuvent-être guidées par un bras mobile en rotation autour de l'axe du mobile de sortie.The figure 17 shows a variant of the conversion mechanism in which the latter is produced with a reduced number of parts, in particular by the combination of eccentric guide functions input, transmission of movement by an arm, pivot function of this arm by flexible element and arc- stop against the receiving disc in one and the same room. The proposed assembly could, however, as in some previous versions be made on two levels to separate two rods. The bracing is always carried out on a member movable in rotation about a virtual pivot, this pivot being preferably a fixed pivot relative to a reference frame of the arm supporting it. In order to ensure the precise guidance of the two clutches around the clutch disc, they can be guided by an arm mobile in rotation about the axis of the output mobile.

En particulier, dans la figure 17, l'organe de transmission 4 comprend deux leviers 42, chacun s'étendant depuis une bascule 41 montée pivotante sur l'organe de guidage 32, et terminée par un organe de blocage 40. L'organe d'embrayage 51 comprend un disque 57 (seulement une moitié du disque est représentée dans la figure 17) pivotant concentriquement avec l'axe 55 d'un pignon 52' de second mobile 5. Chacun des organes de blocage 40 comprend un élément flexible 410 apte à venir en appui contre la tranche 57' du disque 57 en relation d'arc-boutement. L'élément flexible 410 est formé d'une seule pièce avec le levier 42 et la bascule 41. L'arc-boutement est obtenu par le fait que chacun des leviers 42 est monté pivotants sur un élément mobile 501 en rotation autour de l'axe 55 commun du pignon 52' et du disque 57, par l'intermédiaire d'un pivot 402.In particular, in the figure 17 , the transmission member 4 comprises two levers 42, each extending from a rocker 41 pivotally mounted on the guide member 32, and terminated by a locking member 40. The clutch member 51 comprises a disc 57 (only half of the disc is represented in the figure 17 ) pivoting concentrically with the axis 55 of a pinion 52 'of the second mobile 5. Each of the locking members 40 comprises a flexible element 410 adapted to bear against the wafer 57' of the disk 57 in a bracing relationship . The flexible element 410 is formed in one piece with the lever 42 and the latch 41. The bracing is obtained by the fact that each of the levers 42 is pivotally mounted on a mobile element 501 in rotation around the common axis 55 of the pinion 52 'and the disc 57, via a pivot 402.

L'excentricité de l'organe de transmission 4 est définie par la distance entre l'axe de rotation 33 du premier mobile 3 et le centre 35 de l'organe de guidage 32 (voir par exemple la figure 8). Dans un mode de réalisation représenté schématiquement aux figures 18a à 18d, l'organe de guidage 32 comprend un second élément excentrique 36 pouvant se déplacer par rapport à l'organe de guidage 32. Dans l'exemple illustré, le second élément excentrique 36 peut être orienté en rotation autour du centre 37 de l'ouverture de l'organe de guidage 32. En particulier, la figure 18a montre le second élément excentrique 36 disposé de manière à maximiser l'excentricité, c'est-à-dire une distance maximale entre l'axe de rotation 33 (A) du premier mobile 3 et le centre 35 (B) de l'organe de guidage 32. Dans la figure 18c, cette distance A-B est nulle et la distance maximale entre l'axe de rotation 33 du premier mobile 3 et le centre 35 de l'organe de guidage 32 est nulle. Dans la figure 18b, le pivotement du second élément excentrique 36 résulte dans une excentricité (distance A-B) intermédiaire. La frontière entre le second élément excentrique 36 et l'organe de guidage 32 peut être continue comme illustré dans les figures 18a à 18c, permettant un réglage continu du degré d'excentricité. La frontière entre le second élément excentrique 36 et l'organe de guidage 32 peut également avoir une interface non continue, par exemple cannelée ou facettée, comme l'illustre la figure 18d, permettant un réglage du degré d'excentricité par pas, ou encore avoir toute autre forme appropriée.The eccentricity of the transmission member 4 is defined by the distance between the axis of rotation 33 of the first mobile 3 and the center 35 of the guide member 32 (see, for example, FIG. figure 8 ). In an embodiment shown diagrammatically in Figures 18a to 18d , the organ of guide 32 includes a second eccentric member 36 movable relative to the guide member 32. In the illustrated example, the second eccentric member 36 can be rotated about the center 37 of the opening of the 32. In particular, the figure 18a shows the second eccentric element 36 arranged to maximize the eccentricity, that is to say a maximum distance between the axis of rotation 33 (A) of the first mobile 3 and the center 35 (B) of the organ 32. In the figure 18c this distance AB is zero and the maximum distance between the axis of rotation 33 of the first mobile 3 and the center 35 of the guide member 32 is zero. In the figure 18b , the pivoting of the second eccentric element 36 results in an eccentricity (distance AB) intermediate. The boundary between the second eccentric member 36 and the guide member 32 may be continuous as illustrated in FIGS. Figures 18a to 18c , allowing a continuous adjustment of the degree of eccentricity. The boundary between the second eccentric member 36 and the guide member 32 may also have a non-continuous interface, for example fluted or faceted, as illustrated by FIG. figure 18d , allowing an adjustment of the degree of eccentricity in steps, or have any other suitable form.

La variation du degré d'excentricité de l'organe de transmission 4 permet de faire varier les paramètres vitesse/couple de transmission du mécanisme de conversion. Dans le cas où le mécanisme de conversion de l'invention est utilisé dans un mécanisme de remontage automatique d'une montre, la variation du degré d'excentricité de l'organe de transmission 4 permet d'adapter le mécanisme de conversion de l'invention à des calibres de montres ayant des caractéristiques différentes (vitesse de remontage, couple du ressort de barillet, etc.). Il permet également d'adapter le mécanisme de conversion à des conditions extrêmes de remontage de la montre, par exemple dans le cas d'un porter trop dynamique ou, au contraire, trop statique, donc aux conditions de remontage définies par leur porteur. Il permet également d'adapter le mécanisme de conversion aux paramètres de remontage à toute autre situation propre à en requérir l'application.The variation of the degree of eccentricity of the transmission member 4 makes it possible to vary the transmission speed / torque parameters of the conversion mechanism. In the case where the conversion mechanism of the invention is used in an automatic winding mechanism of a watch, the variation of the degree of eccentricity of the transmission member 4 makes it possible to adapt the conversion mechanism of the invention to calibres of watches with different characteristics (winding speed, torque of the mainspring, etc.). It also makes it possible to adapt the conversion mechanism to extreme winding conditions of the watch, for example in the case of wearing too dynamically or, on the contrary, too static, and therefore to the winding conditions defined by their wearer. It also makes it possible to adapt the conversion mechanism to the winding parameters to any other situation that may require its application.

L'homme du métier saura toutefois recourir à tout autre moyen connu pour permettre de procéder à ce réglage (déplacement linéaire le long de l'axe A-B par micro-vis ou tout autre moyen alternatif, etc.)Those skilled in the art will, however, use any other known means to allow this adjustment (linear movement along the axis A-B by micro-screw or other alternative means, etc.)

Dans un mode de réalisation représenté aux figures 19 et 20, l'organe d'embrayage 51 est arrangé de manière à pivoter de façon légèrement excentrée par rapport à l'axe de rotation 55 du second mobile 5. La figure 19 montre un exemple où l'organe de blocage 40 prend la forme d'une portion d'un roulement à billes, où la bille 44 est coincée entre la bague de roulement 53 et la pente de la cage 45, cette pente pouvant être linéaire ou curviligne. La figure 20 montre un exemple où l'organe de blocage 40 comprend un excentrique de blocage 406.In an embodiment shown in Figures 19 and 20 , the clutch member 51 is arranged to pivot slightly eccentrically with respect to the axis of rotation 55 of the second mobile 5. The figure 19 shows an example where the locking member 40 takes the form of a portion of a ball bearing, where the ball 44 is wedged between the bearing ring 53 and the slope of the cage 45, this slope can be linear or curvilinear. The figure 20 shows an example where the locking member 40 comprises a locking eccentric 406.

L'excentricité est illustrée par le tracé en pointillés sur les figures. L'excentricité a pour effet que le blocage / friction de l'élément mobile 44 (excentrique de blocage 406, etc.) se répartit sur une plus grande portion de la surface de l'élément de cage 45. L'occurrence de contacts répétés de blocage / friction aux mêmes endroits de la surface peuvent être ainsi réduite significativement par rapport à une configuration où l'organe d'embrayage 53, 57 pivote de façon concentrique par rapport à l'axe de rotation 55. Les effets de matage ou d'usure dus aux pressions sur l'élément de cage 45 sont minimisés. Un tel arrangement peut être réalisé sans pour autant perturber les paramètres de remontage de manière sensible (dans le cas où le mécanisme de conversion est utilisé dans un mécanisme de remontage automatique d'une montre). Une autre manière de répartir les contraintes et l'usure sur des portions différentes de l'excentrique de blocage 406 ou de l'élément de cage 45, consiste à recourir à un disque d'embrayage 53 concentrique à son centre de rotation 55, en donnant audit disque d'embrayage 53 une forme légèrement ovalisée, par exemple de type ellipsoïdale, ou tout autre géométrie faisant varier légèrement la distance définie entre le point de contact avec l'élément de blocage 406, 44 et le centre de rotation 55.The eccentricity is illustrated by the dotted line in the figures. The eccentricity has the effect that the locking / friction of the movable member 44 (locking eccentric 406, etc.) is distributed over a larger portion of the surface of the cage member 45. The occurrence of repeated contacts In this case, the blocking / frictional engagement at the same points on the surface can be significantly reduced compared with a configuration where the clutch member 53, 57 pivots concentrically with respect to the axis of rotation 55. wear due to the pressures on the cage member 45 are minimized. Such an arrangement can be achieved without disturbing the winding parameters significantly (in the case where the conversion mechanism is used in a mechanism for automatic winding a watch). Another way of distributing the stresses and the wear on different portions of the locking eccentric 406 or of the cage element 45 consists in using a clutch disc 53 concentric with its center of rotation 55, giving to said clutch disk 53 a slightly oval shape, for example of ellipsoidal type, or any other geometry slightly varying the distance defined between the point of contact with the locking element 406, 44 and the center of rotation 55.

Si le mécanisme de conversion a été illustré principalement dans le contexte d'une utilisation dans un mécanisme de remontage automatique d'une montre, le mécanisme de conversion peut également être également être utilisé dans tout autre dispositif de transmission qui requiert la conversion d'un mouvement bidirectionnel en un mouvement unidirectionnel.If the conversion mechanism has been illustrated primarily in the context of use in a winding mechanism The automatic conversion mechanism can also be used in any other transmission device that requires the conversion of bidirectional motion into unidirectional motion.
