A pull-out piece (60) drives the lever to move the pinion.

Description

L'invention concerne un dispositif de commande de remontage et de mise à l'heure pour un mouvement d'horlogerie du type comportant une tige de mouvement rotative autour d'un axe dans une platine de mouvement et solidaire en rotation d'un pignon coulant mobile axialement sous l'action d'une bascule de pignon coulant selon ledit axe en translation entre d'une part une position de remontage dans laquelle ledit pignon coulant est agencé apte à coopérer avec un mécanisme de remontage pour la mise en rotation de ce dernier, et d'autre part une position de mise à l'heure dans laquelle ledit pignon coulant est agencé apte à coopérer avec un mécanisme de mise à l'heure pour la mise en rotation de ce dernier, ledit dispositif comportant, reliée en rotation à ladite tige de mouvement par des moyens de transmission et décalée par rapport à ladite tige de mouvement, une tige de commande rotative autour d'un axe longitudinal et coulissant axialement au moins entre une position de commande de remontage et une position de commande de mise à l'heure et agencée pour coopérer avec une couronne de commande manuelle, ladite bascule de pignon coulant faisant partie d'un mécanisme à tirettes actionné par le coulissement de ladite première tige entre ladite position de commande de remontage et ladite position de commande de mise à l'heure, ledit pignon coulant étant en prise avec ledit mécanisme de remontage dans ladite position de remontage quand ladite tige de commande est en position de commande de remontage, ou avec ledit mécanisme de mise à l'heure quand ladite tige de commande est en position de commande de mise à l'heure.The invention relates to a winding and setting control device for a watch movement of the type comprising a rotary movement rod about an axis in a movement plate and rotatably connected to a sliding pinion axially movable under the action of a sliding pinion according to said translational axis between firstly a winding position in which said sliding pinion is arranged adapted to cooperate with a winding mechanism for the rotation of the latter and on the other hand a setting position in which said sliding pinion is arranged able to cooperate with a time setting mechanism for the rotation of the latter, said device comprising, connected in rotation to said motion rod by transmission means and offset with respect to said motion rod, a rotary control rod about a longitudinal axis and axially slidable at least between a com position winding mechanism and a time setting control position and arranged to cooperate with a manual control ring, said sliding pinion latch forming part of a pull mechanism actuated by the sliding of said first rod between said position of winding control and said time setting control position, said sliding pinion being engaged with said winding mechanism in said winding position when said control rod is in the winding control position, or with said setting mechanism at the time when said control rod is in the time setting control position.

L'invention concerne le domaine des mécanismes de remontage et de mise à l'heure de mouvements d'horlogerie.The invention relates to the field of winding mechanisms and time setting watch movements.

L'utilisation de deux tiges mutuellement décalées en hauteur et liées cinématiquement, à la place de l'habituelle tige de remontoir en une seule pièce ou en deux pièces alignées, peut être avantageuse dans une pièce d'horlogerie mécanique à complications, lorsque les éléments des complications doivent prendre place entre le cadran et le mouvement de base et conduisent donc à placer ce dernier plus bas que le plan médian de la boîte de la pièce d'horlogerie. La couronne extérieure d'une tige de remontoir habituelle se trouverait alors nettement plus près du fond de la boîte que de la lunette, ce qui serait à la fois malcommode et inesthétique. Le dispositif à deux tiges permet de maintenir la couronne à sa place traditionnelle et commode, à mi-hauteur de la boîte.The use of two rods mutually offset in height and kinematically linked, instead of the usual winding stem in one piece or in two aligned pieces, can be advantageous in a mechanical timepiece with complications, when the elements complications must take place between the dial and the base movement and lead to placing the latter lower than the median plane of the timepiece box. The outer crown of a usual winding stem would then be much closer to the bottom of the box than the bezel, which would be both awkward and unsightly. The device with two rods keeps the crown in its traditional and convenient place, halfway up the box.

Dans les dispositifs connus de ce genre, par exemple ceux décrits dans le brevet CH 691 632 au nom de Chopard International SA et dans le brevet EP 1 134 628 au nom de Dubois & Depraz SA, les deux tiges sont reliées en rotation par une transmission à engrenage et sont en outre solidarisées en translation, de sorte que la seconde tige suit la première lorsque l'utilisateur tire la couronne de commande. Il en résulte que la seconde tige, à savoir celle qui s'étend à l'intérieur du mouvement, remplit là toutes les fonctions d'une tige classique et doit être équipée des mêmes organes (tirette, pignon coulant, pignon de remontage) qu'une tige classique. A cause de la place occupée par l'engrenage reliant les deux tiges, le constructeur est obligé de décaler quelque peu ces organes vers l'intérieur du mouvement. En outre, la liaison pour solidariser en translation les deux tiges nécessite un bâti mobile contenant l'engrenage et augmentant l'encombrement du dispositif. Les jeux en direction axiale existant inévitablement dans ce bâti entraînent des imprécisions dans les positions axiales de la première tige, étant donné que l'indexage de la position axiale se fait en principe sur la seconde tige.In the known devices of this kind, for example those described in the patent CH 691 632 in the name of Chopard International SA and in the patent EP 1 134 628 in the name of Dubois & Depraz SA, the two rods are connected in rotation by a gear transmission and are further secured in translation, so that the second rod follows the first when the user pulls the control ring. It follows that the second rod, namely that which extends inside the movement, fulfills all the functions of a conventional rod and must be equipped with the same bodies (zipper, sliding pinion, winding pinion) that a classic stem. Because of the place occupied by the gear connecting the two rods, the manufacturer is obliged to shift some of these organs towards the inside of the movement. In addition, the link for securing in translation the two rods requires a mobile frame containing the gear and increasing the size of the device. Axially axial play inevitably existing in this frame cause inaccuracies in the axial positions of the first rod, since the indexing of the axial position is in principle on the second rod.

Les deux tiges du dispositif de remontage et de mise à l'heure décrit dans le document de brevet DE 593 654 au nom de Wilhelm Koehler sont également reliées en rotation par une transmission à engrenage et solidarisées en translation. Le dispositif décrit dans ce dernier document diffère des précédents en ce qu'il ne comporte ni pignon coulant, ni mécanisme à tirette. La commutation en position mise à l'heure se fait en pressant sur la couronne de remontoir. Selon ce document, la seconde tige porte une roue à couronne qui vient engrener avec le mécanisme de mise à l'heure lorsque les tiges se déplacent en translation en réaction à la pression exercée par l'utilisateur sur la couronne de remontoir.The two rods of the winding and setting device described in the patent document DE 593 654 in the name of Wilhelm Koehler are also connected in rotation by a gear transmission and secured in translation. The device described in the latter document differs from the previous ones in that it comprises neither sliding pinion nor pull mechanism. Switching to the time setting position is done by pressing the winding crown. According to this document, the second rod carries a crown wheel which meshes with the time setting mechanism when the rods move in translation in response to the pressure exerted by the user on the winding crown.

On connaît une bonne solution au problème de maintien de la couronne de remontage et de mise à l'heure dans le plan médian du la boîte de pièce d'horlogerie, par le document de brevet EP 1 748 330 au nom de MONTRES BREGUET SA, qui décrit un dispositif avec une première tige rotative coulissante axialement entre une position de remontage et une position de mise à l'heure, fixée à la couronne de la pièce d'horlogerie, et une seconde tige parallèle et décalée par rapport à la première et pourvue de moyens pour entraîner en rotation sélectivement un mécanisme de remontage et un mécanisme de mise à l'heure. Ces deux tiges sont reliées en rotation par une transmission. La seconde tige est solidaire en rotation d'un pignon coulant, mobile axialement entre deux positions sous l'action d'une bascule. Une extrémité de cette bascule est engagée dans une rainure périphérique du pignon coulant. La bascule fait partie d'un mécanisme à tirette actionné par le coulissement de la première tige entre ses positions respectives de remontage et de mise à l'heure, où le pignon coulant est en prise respectivement avec le mécanisme de remontage et avec le mécanisme de mise à l'heure.There is a good solution to the problem of maintaining the winding crown and setting the time in the median plane of the timepiece box by the patent document. EP 1 748 330 in the name of WATCHES BREGUET SA, which describes a device with a first rotating shaft axially sliding between a winding position and a time setting position, fixed to the crown of the timepiece, and a second rod parallel and offset from the first and provided with means for selectively rotating a winding mechanism and a time setting mechanism. These two rods are connected in rotation by a transmission. The second rod is integral in rotation with a sliding pinion, axially movable between two positions under the action of a rocker. One end of this rocker is engaged in a peripheral groove of the sliding pinion. The rocker is part of a pull mechanism actuated by the sliding of the first rod between its respective positions of winding and setting time, where the sliding pinion is respectively engaged with the winding mechanism and with the mechanism of setting the time.

L'invention vise à créer un dispositif perfectionné par rapport à l'état de la technique, dans le sens d'une plus grande simplicité et d'un moindre encombrement, et avec une facilité d'intégration sur un mouvement existant.The object of the invention is to create an improved device with respect to the state of the art, in the sense of greater simplicity and less space, and with ease of integration with an existing movement.

A cet effet, l'invention concerne un dispositif de commande de remontage et de mise à l'heure pour un mouvement d'horlogerie du type comportant une tige de mouvement rotative autour d'un axe dans une platine de mouvement et solidaire en rotation d'un pignon coulant mobile axialement sous l'action d'une bascule de pignon coulant selon ledit axe en translation entre d'une part une position de remontage dans laquelle ledit pignon coulant est agencé apte à coopérer avec un mécanisme de remontage pour la mise en rotation de ce dernier, et d'autre part une position de mise à l'heure dans laquelle ledit pignon coulant est agencé apte à coopérer avec un mécanisme de mise à l'heure pour la mise en rotation de ce dernier, ledit dispositif comportant, reliée en rotation à ladite tige de mouvement par des moyens de transmission et décalée par rapport à ladite tige de mouvement, une tige de commande rotative autour d'un axe longitudinal et coulissant axialement au moins entre une position de commande de remontage et une position de commande de mise à l'heure et agencée pour coopérer avec une couronne de commande manuelle, ladite bascule de pignon coulant faisant partie d'un mécanisme à tirettes actionné par le coulissement de ladite première tige entre ladite position de commande de remontage et ladite position de commande de mise à l'heure, ledit pignon coulant étant en prise avec ledit mécanisme de remontage dans ladite position de remontage quand ladite tige de commande est en position de commande de remontage, ou avec ledit mécanisme de mise à l'heure quand ladite tige de commande est en position de commande de mise à l'heure, caractérisé en ce que ledit mécanisme à tirettes comporte une première tirette faisant levier et comportant, de part et d'autre d'un premier axe de pivotement, un bras de première tirette mobile en translation sous l'effet d'une translation de ladite tige de commande, et un pivot, lequel coopère, selon un troisième axe de pivotement, avec un pivot complémentaire que comporte une seconde tirette faisant levier et comportant, de part et d'autre d'un second axe de pivotement, d'une part un bras de seconde tirette mobile dans un logement que comporte ladite tige de mouvement, et d'autre part ledit pivot complémentaire, ladite seconde tirette entraînant ladite bascule de pignon coulant pour déplacer ledit pignon coulant.For this purpose, the invention relates to a winding and setting control device for a watch movement of the type comprising a rotary movement rod about an axis in a platinum movement and integral in rotation with a sliding pinion axially movable under the action of a pinion pinion flowing along said axis in translation between on the one hand a winding position in which said pinion is arranged able to cooperate with a winding mechanism for the rotation of the latter, and secondly a setting position in which said sliding pinion is arranged adapted to cooperate with a time setting mechanism for rotating of the latter, said device comprising, connected in rotation with said movement rod by transmission means and offset relative to said movement rod, a rotary control rod about a longitudinal axis and sliding axially at least between a position winding control and a time setting control position and arranged to cooperate with a manual control ring, said sliding pinion latch being part of a pull-rod mechanism actuated by the sliding of said first rod between said winding control position and said time setting control position, said sliding pinion being engaged with said winding mechanism in said winding position when said rod of control is in the winding control position, or with said time setting mechanism when said control rod is in the time setting control position, characterized in that said pull mechanism comprises a first lever lever and comprising, on either side of a first pivot axis, a first movable tongue movable in translation under the effect of a translation of said control rod, and a pivot, which cooperates along a third axis pivoting, with a complementary pivot that comprises a second lever lever and having, on either side of a second axis of pivoting, on the one hand an arm of second drawbar m obile in a housing that includes said movement rod, and secondly said complementary pivot, said second pulling said sliding pinion to move said sliding pinion.

Selon une caractéristique de l'invention, ledit second axe de pivotement est aligné avec ledit premier axe de pivotement, de façon à assurer des débattements angulaires identiques desdites première tirette et seconde tirette lors d'une action sur ladite tige de commande.According to a characteristic of the invention, said second pivot axis is aligned with said first pivot axis, so as to ensure identical angular movements of said first pull and second pull when acting on said control rod.

Selon une autre caractéristique de l'invention, ledit axe longitudinal de ladite tige de commande est parallèle audit axe de ladite tige de mouvement, et lesdits moyens de transmission comportent un nombre impair supérieur ou égal à un de pignons de renvoi, et l'axe d'au moins un desdits pignons de renvoi est décalé par rapport au plan constitué par ledit axe longitudinal de ladite tige de commande et ledit axe de ladite tige de mouvement.According to another characteristic of the invention, said longitudinal axis of said control rod is parallel to said axis of said motion rod, and said transmission means comprise an odd number greater than or equal to one of idler pinions, and the axle at least one of said idler gears is offset with respect to the plane constituted by said longitudinal axis of said control rod and said axis of said movement rod.

Ainsi, la commutation entre le remontage et la mise à l'heure grâce au déplacement axial de la première tige est effectuée sur la seconde tige au moyen d'un mécanisme à tirette amélioré, de faible encombrement et particulièrement rigide, qui évite les inconvénients susmentionnés d'un bâti mobile en translation. Le dispositif à tirette a l'avantage d'être éprouvé et de faible hauteur. La position du pignon de renvoi intermédiaire décalé autorise toute valeur d'entraxe désirée entre la tige de commande et la tige de mouvement.Thus, switching between reassembly and time setting by axial displacement of the first rod is performed on the second rod by means of an improved pull mechanism, compact and particularly rigid, which avoids the aforementioned disadvantages a mobile frame in translation.

L'invention concerne le domaine des mécanismes de remontage et de mise à l'heure de mouvements d'horlogerie.The invention relates to the field of winding mechanisms and time setting watch movements.

L'invention concerne un dispositif 100 de commande de remontage et de mise à l'heure pour un mouvement d'horlogerie.The invention relates to a device 100 for winding and setting control for a watch movement.

Le dispositif représenté dans les dessins comprend deux tiges de remontoir et de mise à l'heure, à savoir une tige de commande 1 et une tige de mouvement 2, dont les axes de rotation respectifs 3 et 4 sont parallèles, mais décalés mutuellement en hauteur, dans une direction perpendiculaire ou oblique par rapport au plan général du mouvement de la pièce d'horlogerie. Ces tiges 1 et 2 sont reliées par deux liaisons cinématiques, à savoir une transmission à engrenage 5, qui est en prise permanente et transmet la rotation d'une tige à l'autre, et un mécanisme à tirette 6, qui transmet des mouvements axiaux de la première tige 1 à un pignon coulant 8. L'ensemble du dispositif est supporté, à partir d'une platine du mouvement 11 de la pièce d'horlogerie, par des éléments fixes ou ponts. Sur ces éléments fixes sont montés également un mécanisme de remontage 20, dont on voit dans les dessins un pignon de remontoir 21, et un mécanisme de mise à l'heure 24, dont on voit dans les dessins un renvoi de minuterie 25.The device shown in the drawings comprises two winding and setting rods, namely a control rod 1 and a movement rod 2, the respective axes of rotation 3 and 4 are parallel, but mutually offset in height , in a perpendicular or oblique direction relative to the general plane of the movement of the timepiece. These rods 1 and 2 are connected by two kinematic links, namely a gear transmission 5, which is in permanent engagement and transmits rotation from one rod to the other, and a pull mechanism 6, which transmits axial movements. from the first rod 1 to a sliding pinion 8. The entire device is supported, from a platen of the movement 11 of the timepiece, by fixed elements or bridges. On these fixed elements are also mounted a winding mechanism 20, which can be seen in the drawings a winding pinion 21, and a time setting mechanism 24, which can be seen in the drawings a timer reference 25.

Le mouvement d'horlogerie auquel il est ici fait référence est du type classique, comportant une tige de mouvement 2 rotative autour d'un axe 4 longitudinal, et guidée, au moins sur une portée 2A, dans une platine de mouvement 11. La tige de mouvement 2 est solidaire en rotation d'un pignon coulant 8, qui est mobile axialement, sous l'action d'une bascule de pignon coulant 52, selon cet axe 4. Ce pignon coulant 8 est mobile en translation entre d'une part une position de remontage dans laquelle il est agencé apte à coopérer avec un mécanisme de remontage 20 pour la mise en rotation de ce dernier, et d'autre part une position de mise à l'heure dans laquelle ce pignon coulant 8 est agencé apte à coopérer avec un mécanisme de mise à l'heure 24 pour la mise en rotation de ce dernier. Le pignon coulant 8 est monté de manière coulissante sur une section carrée 9 de la tige de mouvement 2, dont il est solidaire en rotation grâce à son orifice central carré. Dans le mode de réalisation représenté sur les figures, la tige de mouvement 2 n'est pas coulissante, c'est-à-dire que sa position axiale est fixe. Les deux extrémités de la tige de mouvement 2 sont de préférence pourvues de pivots cylindriques. Un palier ou une pierre 42 montée dans un flasque 15 et un alésage 43 de la platine de mouvement 11 forment des paliers de rotation qui supportent la tige 2 et la maintiennent axialement. Sur cette tige est fixé un pignon 44 qui s'engrène en permanence sur un pignon intermédiaire 45 et constitue ainsi le dernier pignon de la transmission à engrenage.The watch movement to which reference is made here is of the conventional type, comprising a movement rod 2 rotatable about a longitudinal axis 4, and guided, at least on a bearing surface 2A, in a movement plate 11. The rod movement 2 is integral in rotation with a sliding pinion 8, which is axially movable, under the action of a sliding pinion rocker 52, along this axis 4. This sliding pinion 8 is movable in translation between on the one hand a winding position in which it is arranged able to cooperate with a winding mechanism 20 for the rotation of the latter, and secondly a position of setting time in which this sliding pinion 8 is arranged adapted to cooperate with a time setting mechanism 24 for the rotation of the latter. The sliding pinion 8 is slidably mounted on a square section 9 of the movement rod 2, which it is secured in rotation by means of its square central opening. In the embodiment shown in the figures, the movement rod 2 is not sliding, that is to say that its axial position is fixed. Both ends of the movement rod 2 are preferably provided with cylindrical pivots. A bearing or a rock 42 mounted in a flange 15 and a bore 43 of the movement plate 11 form rotational bearings which support the rod 2 and hold it axially. On this rod is fixed a pinion 44 which meshes permanently on an intermediate gear 45 and thus constitutes the last gear of the gear transmission.

La tige de mouvement 2 comporte un arrêt, sous forme d'un épaulement droit ou conique, sur lequel peut s'appuyer un pignon de remontoir 21, qui est monté fou sur une portée cylindrique 46 de la tige de mouvement 2. Le pignon 21 est de construction classique, comportant de préférence une denture de chant 47 de type Breguet, capable de coopérer avec une denture de chant correspondante 48 du pignon coulant 8 quand celui-ci est en position de remontage, et une denture droite 49 engrenée en permanence avec un renvoi non représenté sur les figures. L'autre extrémité du pignon coulant 8 est pourvue d'une denture de chant 50 conçue pour engrener avec le renvoi de minuterie 25, quand le pignon coulant 8 est en position de mise à l'heure. Le pignon coulant 8 a en outre une rainure périphérique 51 dans laquelle est engagée une bascule de pignon coulant 52.The movement rod 2 comprises a stop, in the form of a straight or conical shoulder, on which can rest a winding pinion 21, which is mounted loosely on a cylindrical surface 46 of the movement rod 2. The pinion 21 is of conventional construction, preferably having a Breguet type edge toothing 47, capable of cooperating with a corresponding edge toothing 48 of the sliding pinion 8 when the latter is in the winding position, and a straight toothing 49 permanently engaged with a reference not shown in the figures. The other end of the sliding pinion 8 is provided with an edge toothing 50 designed to mesh with the timer gear 25, when the sliding pinion 8 is in the setting position. The sliding pinion 8 furthermore has a peripheral groove 51 in which a sliding pinion 52 is engaged.

Le dispositif 100 comporte, reliée en rotation à la tige de mouvement 2 par des moyens de transmission 5, et décalée par rapport à la tige de mouvement 2, c'est-à-dire non alignée avec elle, une tige de commande 1. Cette tige de commande 1 est rotative autour d'un axe longitudinal 3, et coulisse axialement au moins entre une position de commande de remontage et une position de commande de mise à l'heure. De préférence, la tige de commande 1 est agencée pour coopérer avec une couronne de commande manuelle, non représentée sur les figures. De façon préférée, l'axe 3 de la tige de commande 1 est parallèle à l'axe 4 de la tige de mouvement 2, tel que représenté sur les figures 1 et 2. La tige 1 de commande comporte de préférence une première partie cylindrique 30 et une seconde partie cylindrique 31, de diamètre plus petit que celui de la première, et celles-ci sont montées de manière coulissante dans des alésages des éléments fixes 14 et 13 d'une platine 16 servant de paliers, de sorte que la tige de commande 1 peut coulisser entre la position de remontage et la position de mise à l'heure. Dans d'autres modes de réalisation, une troisième position de la tige 1 pourrait être prévue, par exemple pour la mise à la date. Comme une tige de remontoir classique, la tige 1 comporte une extrémité filetée 32 destinée à traverser la carrure de la boîte de pièce d'horlogerie et à porter une couronne manuelle de commande à l'extérieur de cette boîte.The device 100 comprises, connected in rotation to the movement rod 2 by transmission means 5, and offset with respect to the movement rod 2, that is to say non-aligned with it, a control rod 1. This control rod 1 is rotatable about a longitudinal axis 3, and slides axially at least between a position of winding command and a time setting command position. Preferably, the control rod 1 is arranged to cooperate with a manual control ring, not shown in the figures. Preferably, the axis 3 of the control rod 1 is parallel to the axis 4 of the movement rod 2, as shown in FIGS. figures 1 and 2 . The control rod 1 preferably comprises a first cylindrical portion 30 and a second cylindrical portion 31, of smaller diameter than that of the first, and these are slidably mounted in bores of the fixed elements 14 and 13 of FIGS. a plate 16 serving as bearings, so that the control rod 1 can slide between the winding position and the time setting position. In other embodiments, a third position of the rod 1 could be provided, for example for setting the date. Like a conventional winding stem, the rod 1 has a threaded end 32 intended to pass through the middle of the timepiece box and to carry a manual control ring outside this box.

Une partie à section carrée 34 de la tige 1 est engagée dans un orifice de section correspondante d'un premier pignon 35 qui est retenu axialement entre les éléments fixes 13 et 14. L'orifice central du pignon 35 peut comporter en outre un tronçon à section circulaire emboîtable sur une partie cylindrique de l'élément 13, cette partie servant de palier pour supporter radialement le pignon 35 lorsque la tige 1 est enlevée, par exemple pour l'emboîtage du mouvement. Dans la partie cylindrique 30 de la tige 1, il est prévu une rainure annulaire 41 dans laquelle est engagé un tenon ou bras 40A d'une première tirette 40. Celle-ci peut être abaissée pour dégager ce tenon de la rainure lorsqu'un horloger veut retirer la tige 1.A square section portion 34 of the rod 1 is engaged in a correspondingly sectioned hole of a first pinion 35 which is retained axially between the fixed elements 13 and 14. The central hole of the pinion 35 may further comprise a section to circular section engageable on a cylindrical portion of the element 13, this portion serving as a bearing for radially supporting the pinion 35 when the rod 1 is removed, for example for the casing of the movement. In the cylindrical portion 30 of the rod 1, there is provided an annular groove 41 in which is engaged a tenon or arm 40A of a first pull tab 40. This can be lowered to release this pin from the groove when a watchmaker wants to remove the rod 1.

La bascule de pignon coulant 52 fait partie d'un mécanisme à tirettes 6, lequel est actionné par le coulissement de la première tige 1 entre la position de commande de remontage et la position de commande de mise à l'heure. Le pignon coulant 8 est en prise avec le mécanisme de remontage 20 dans la position de remontage quand la tige de commande 1 est en position de commande de remontage. Ou bien le pignon coulant 8 est en prise avec le mécanisme de mise à l'heure 24, quand la tige de commande 1 est en position de commande de mise à l'heure.The sliding pinion 52 is part of a pull mechanism 6, which is actuated by the sliding of the first rod 1 between the winding control position and the time setting control position. The sliding pinion 8 is engaged with the winding mechanism 20 in the winding position when the control rod 1 is in the winding control position. Or the sliding pinion 8 is engaged with the time setting mechanism 24, when the control rod 1 is in the time setting control position.

Selon l'invention, le mécanisme à tirettes 6 comporte une première tirette 40, coopérant avec la tige de commande 1. Cette première tirette 40 fait levier et comporte, de part et d'autre d'un premier axe de pivotement A1, d'une part un bras de première tirette 40A mobile en translation sous l'effet d'une translation de la tige de commande 1, et d'autre part un pivot 40B. Ce pivot 40B coopère, selon un troisième axe de pivotement A3, avec un pivot complémentaire 60B que comporte une seconde tirette 60. De façon similaire à la première tirette 40, cette seconde tirette 60 fait levier, et comporte, de part et d'autre d'un second axe de pivotement A2, d'une part un bras de seconde tirette 60A mobile, notamment en translation, dans un logement 61 que comporte la tige de mouvement 2, et d'autre part ce pivot complémentaire 60B. La seconde tirette 60 entraîne la bascule de pignon coulant 52 pour déplacer le pignon coulant 8.According to the invention, the drawbar mechanism 6 comprises a first pull tab 40, cooperating with the control rod 1. This first pull tab 40 is lever and comprises, on either side of a first pivot axis A1, of firstly a first pull arm 40A movable in translation under the effect of a translation of the control rod 1, and secondly a pivot 40B. This pivot 40B cooperates, along a third pivot axis A3, with a complementary pivot 60B that includes a second pull tab 60. Similar to the first pull tab 40, this second pull tab 60 lever, and comprises, on both sides a second pivot axis A2, on the one hand a second movable second arm 60A, in particular in translation, in a housing 61 that includes the movement rod 2, and on the other hand the complementary pivot 60B. The second puller 60 drives the sliding pinion 52 to move the sliding pinion 8.

Naturellement, le mécanisme à tirettes, décrit ici dans une réalisation simple et avantageuse à deux tirettes, peut comporter davantage de tirettes, coopérant entre elles de la même façon pivotée, sans s'éloigner de l'esprit de l'invention.Naturally, the drawbar mechanism, described here in a simple and advantageous embodiment with two drawbars, may comprise more drawbars, cooperating with each other in the same rotated manner, without departing from the spirit of the invention.

De façon préférée, tel que visible sur la figure 2, le bras de première tirette 40A est engagé dans une première gorge 41 que comporte la première tige 1. la largeur de cette première gorge 41 autorise tout juste le pivotement de bras 40A, un mouvement longitudinal de la tige de commande 1 est ainsi répercuté avec un jeu minimal à l'embiellage formé de la première tirette 40 et de la seconde tirette 60.Preferably, as visible on the figure 2 , the first pull arm 40A is engaged in a first groove 41 that includes the first rod 1. the width of this first groove 41 just allows the pivoting arm 40A, a longitudinal movement of the control rod 1 is thus echoed with a minimum game with the linkage formed of the first zipper 40 and the second zipper 60.

Le bras de seconde tirette 60A est préférablement engagé dans une seconde gorge 61 que comporte la tige de mouvement 2. De préférence, la tige de mouvement 2 est immobile en translation, et de ce fait la gorge 61 est de largeur supérieure à celle du bras de seconde tirette 60A, de façon à autoriser son débattement complet.The second puller arm 60A is preferably engaged in a second groove 61 that includes the movement rod 2. Preferably, the movement rod 2 is immobile in translation, and thus the groove 61 is wider than that of the second pull arm 60A, so as to allow its complete movement.

La bascule de pignon coulant 52 comporte un bras 53 solidaire en translation avec le pignon coulant 8, de préférence par coopération avec une gorge 51 de ce dernier, dans laquelle il est engagé, avec un jeu fonctionnel minimal de façon similaire à la coopération entre le bras de première tirette 40A et la première gorge 41.The sliding pinion rocker 52 comprises an arm 53 integral in translation with the sliding pinion 8, preferably by cooperation with a groove 51 of the latter, in which it is engaged, with a minimum functional clearance in a manner similar to the cooperation between the 40A first pull arm and the first groove 41.

De façon préférée, tel que visible sur les figures 2 à 5, le second axe de pivotement A2 est parallèle audit premier axe de pivotement A1. Et, de façon avantageuse, le second axe de pivotement A2 est aligné avec le premier axe de pivotement A1, de façon à assurer des débattements angulaires identiques de la première tirette 40 et de la seconde tirette 60 lors d'une action sur la tige de commande 1.Preferably, as visible on the Figures 2 to 5 the second pivot axis A2 is parallel to said first pivot axis A1. And, advantageously, the second pivot axis A2 is aligned with the first pivot axis A1, so as to ensure identical angular displacements of the first pull tab 40 and the second pull tab 60 during an action on the rod. order 1.

On comprend que la seconde tirette 60, qui est située au niveau du mouvement, ou qui y est intégrée, est utilisée pour actionner la bascule de pignon coulant 52, en reproduisant à l'identique le mouvement déporté imprimé à première tirette 40 par la tige de commande 1. Dans un mode particulier de réalisation, tel que visible sur la figure 3, la seconde tirette 60 comporte une liaison articulée avec la bascule de pignon coulant 52 par une liaison pivotée autour d'un axe de pivotement A4.It will be understood that the second pull tab 60, which is situated at the level of the movement, or which is integrated therein, is used to actuate the sliding pinion rocker 52, reproducing identically the offset movement printed at first pull rod 40 by the rod. 1. In a particular embodiment, as visible on the figure 3 , the second pull tab 60 comprises an articulated connection with the sliding pinion rocker 52 by a connection pivoted about a pivot axis A4.

En ce qui concerne les moyens de transmission 5, ils comportent de préférence un nombre impair de pignons de renvoi 45, de façon à ce que la tige de mouvement 2 soit entraînée dans le même sens de rotation que la tige de commande 1. Ce nombre de pignons 45 est supérieur ou égal à un. De façon avantageuse pour une réalisation économique, chacun des pignons de renvoi 45 est d'axe parallèle à l'axe 4 de la tige de mouvement 2.As regards the transmission means 5, they preferably comprise an odd number of pinion gears 45, so that the movement rod 2 is driven in the same direction of rotation as the control rod 1. This number pinion 45 is greater than or equal to one. Advantageously for an economical embodiment, each of the pinion gears 45 is of axis parallel to the axis 4 of the movement rod 2.

De préférence, l'axe d'au moins un de ces pignons de renvoi 45 est décalé par rapport au plan constitué par l'axe longitudinal 3 de la tige de commande 1 et par l'axe 4de la tige de mouvement 2, quand ces deux axes sont coplanaires, de préférence parallèles. Une telle position du pignon de renvoi intermédiaire 45 décalé autorise l'adaptation du dispositif 100 à toute valeur d'entraxe désirée entre la tige de commande 1 et la tige de mouvement 2.Preferably, the axis of at least one of these pinion gears 45 is offset with respect to the plane constituted by the longitudinal axis 3 of the control rod 1 and the axis 4 of the movement rod 2, when these two axes are coplanar, preferably parallel. Such a position of the intermediate shift gear 45 allows the adaptation of the device 100 to any desired value between the control rod 1 and the movement rod 2.

De façon préférée, tel que visible sur les figures 1 et 2, le dispositif 100 comporte une planche additionnelle 16 agencée pour être fixée sur la platine de mouvement 11, et qui comporte des moyens de guidage en rotation 17 de la tige de commande 1.Preferably, as visible on the figures 1 and 2 , the device 100 comprises an additional plate 16 arranged to be fixed on the movement plate 11, and which comprises means for guiding in rotation 17 of the control rod 1.

Le dispositif 100 comporte encore un carter 70, qui est agencé pour être fixé sur la plaque additionnelle 16 et contenir les moyens de transmission 5, en coopération avec un flasque de fermeture 15 agencé pour fermer ce carter 70, et pour constituer des moyens de guidage en pivotement des moyens de transmission 5. Tel que visible sur la figure 1, ces moyens de guidage en pivotement peuvent en particulier consister en un palier 75 ménagé au niveau du flasque 15, et en un palier 76 au niveau du carter 70. Naturellement, si les moyens de transmission 5 comportent plusieurs pignons intermédiaires de type du pignon 45, autant de paliers similaires sont agencés au niveau du carter 70 et de son flasque de fermeture 15.The device 100 also comprises a casing 70, which is arranged to be fixed on the additional plate 16 and to contain the transmission means 5, in cooperation with a closing flange 15 arranged to close this casing 70, and to constitute guide means pivoting of the transmission means 5. As visible on the figure 1 these pivoting guide means may in particular consist of a bearing 75 formed at the flange 15, and a bearing 76 at the housing 70. Naturally, if the transmission means 5 comprise a plurality of pinion-type intermediate gears 45 , as many similar bearings are arranged at the housing 70 and its closure flange 15.

De façon avantageuse, tel que visible sur la figure 2, la planche additionnelle 16 comporte au moins un palier 73 agencé pour la réception d'un pivot 71 que comporte la première tirette 40, et qui constitue le premier axe de pivotement A1.Advantageously, as visible on the figure 2 , the additional board 16 comprises at least one bearing 73 arranged for the reception of a pivot 71 that includes the first pull tab 40, and which constitutes the first pivot axis A1.

Face à ce palier 73, la platine de mouvement 11 comporte au moins un palier 74 pour la réception d'un pivot 72, que comporte la seconde tirette 60, et qui constitue le second axe de pivotement A2.Faced with this bearing 73, the movement plate 11 comprises at least one bearing 74 for the reception of a pivot 72, which comprises the second pull tab 60, and which constitutes the second pivot axis A2.

L'invention concerne encore une pièce d'horlogerie comportant au moins un mouvement d'horlogerie du type précédemment décrit comportant une tige de mouvement 2 rotative autour d'un axe 4 dans une platine de mouvement 11 et solidaire en rotation d'un pignon coulant 8 mobile axialement sous l'action d'une bascule de pignon coulant 52 selon cet axe 4 en translation entre d'une part une position de remontage dans laquelle le pignon coulant 8 est agencé apte à coopérer avec un mécanisme de remontage 20 pour la mise en rotation de ce dernier, et d'autre part une position de mise à l'heure dans laquelle ce pignon coulant 8 est agencé apte à coopérer avec un mécanisme de mise à l'heure 24 pour la mise en rotation de ce dernier. Selon l'invention, cette pièce d'horlogerie comporte au moins un tel dispositif 100, associé à un de ces mouvements.The invention also relates to a timepiece comprising at least one watch movement of the type previously described comprising a rotating movement rod 2 about an axis 4 in a movement plate 11 and integral in rotation with a sliding pinion 8 mobile axially under the action of a sliding pinion rocker 52 along said axis 4 in translation between on the one hand a winding position in which the sliding pinion 8 is arranged adapted to cooperate with a winding mechanism 20 for rotating of the latter, and secondly a setting time position in which the sliding pinion 8 is arranged able to cooperate with a setting mechanism 24 for the rotation of the latter. According to the invention, this timepiece comprises at least one such device 100, associated with one of these movements.

De façon préférée, la tige de mouvement 2 de cette pièce d'horlogerie est immobilisée en translation. Selon une variante non représentée, la tige de mouvement 2 pourrait être coulissante et solidaire du pignon coulant 8. Le pignon 44 devrait alors être plus long afin de rester engrené avec le pignon intermédiaire 45 pendant ce coulissement. En outre, le pignon de remontoir 21 devrait être maintenu axialement pour ne pas coulisser avec la tige de mouvement 2, c'est-à-dire que la longueur de la construction serait un peu plus grande que celle qui apparaît dans la figure 1.Preferably, the movement rod 2 of this timepiece is immobilized in translation. According to a variant not shown, the movement rod 2 could be sliding and secured to the sliding pinion 8. The pinion 44 should then be longer to stay in mesh with the intermediate pinion 45 during this sliding. In addition, the winding pinion 21 should be held axially so as not to slide with the movement rod 2, that is to say that the length of the construction would be a little larger than that which appears in the figure 1 .
