MÉCANISME D'ENTRAÎNEMENT INSTANTANÉ POUR  INSTANT TRAINING MECHANISM FOR
MOUVEMENT HORLOGER  WATCHMAKING MOVEMENT
Domaine technique  Technical area
[0001 ] La présente invention concerne un mécanisme d'entraînement instantané pour mouvement horloger comportant un mobile et un levier destinés à être montés pivotants sur au moins un élément de bâti du mouvement horloger. Plus précisément, le levier est agencé pour coopérer, d'une part, avec le mobile pour être déplacé et, d'autre part, avec un compteur du mouvement horloger, dans le but de l'incrémenter au moyen d'impulsions instantanées. Par ailleurs, le mobile comprend une première roue, destinée à être entraînée à partir d'un organe d'entraînement du mouvement horloger et, agencée pour entraîner en rotation une première came du mobile, coaxiale à la première roue et, présentant une périphérie de rayon variable. Cette dernière est agencée pour coopérer avec un bec porté par un premier bras du levier et l'éloigner progressivement du centre du mobile lorsque ce dernier tourne dans un premier sens de rotation, avant de le laisser chuter, sous l'effet de l'action de moyens élastiques, lorsque le bec se déplace d'un point de la périphérie correspondant au rayon le plus grand vers un point de la périphérie correspondant au rayon le plus faible. The present invention relates to an instant drive mechanism for a watch movement comprising a mobile and a lever intended to be pivotally mounted on at least one frame member of the watch movement. More specifically, the lever is arranged to cooperate, on the one hand, with the mobile to be moved and, on the other hand, with a counter of the watch movement, with the aim of incrementing it by means of instantaneous pulses. Furthermore, the mobile comprises a first wheel, intended to be driven from a drive member of the watch movement and arranged to drive in rotation a first cam of the mobile, coaxial with the first wheel and, having a periphery of variable radius. The latter is arranged to cooperate with a spout carried by a first arm of the lever and away from the center of the mobile when the latter rotates in a first direction of rotation, before letting it fall, under the effect of the action elastic means, when the spout moves from a point of the periphery corresponding to the largest radius to a point of the periphery corresponding to the smallest radius.
Etat de la technique State of the art
[0002] Des dispositifs de ce type ont déjà été divulgués, comme par exemple dans la demande de brevet EP 1406131 A1 , qui décrit un mécanisme horloger agencé pour entraîner, par sauts instantanés successifs, des disques d'affichage des heures et des minutes courantes.  Devices of this type have already been disclosed, as for example in the patent application EP 1406131 A1, which describes a clock mechanism arranged to drive, by successive instantaneous jumps, display disks hours and minutes minutes .
[0003] A cet effet, ce mécanisme comporte, pour chacune de ces deux unités de temps à afficher, un mobile comprenant une roue d'entraînement et une came coaxiale à cette roue et présentant une périphérie de rayon variable, plus précisément en dents de scie. La came est solidaire en rotation de la roue d'entraînement, cette dernière étant entraînée à partir d'un rouage de finissage. Un levier pivotant est agencé pour coopérer d'une part avec la came, par l'intermédiaire d'un bec, et, d'autre part, avec un compteur de l'unité de temps correspondante, par l'intermédiaire d'une bascule portant un cliquet et avec laquelle il engrène. For this purpose, this mechanism comprises, for each of these two time units to be displayed, a mobile comprising a drive wheel and a cam coaxial with this wheel and having a periphery of variable radius, more precisely in teeth of saw. The cam is integral in rotation with the drive wheel, the latter being driven from a finishing train. A pivoting lever is arranged to cooperate on the one hand with the cam, via a spout, and, on the other hand, with a counter of the corresponding unit of time, via a rocker carrying a ratchet and with which it meshes.
[0004] Des moyens élastiques sont prévus pour appliquer le bec en permanence contre la périphérie de la came, ainsi le levier pivote tandis que le bec suit le profil montant d'une dent de scie de la came, avant de chuter lorsque le bec se trouve en regard de la face radiale de cette même dent. La chute du bec, et donc le retour du levier dans sa position la plus proche de la came, entraîne une incrémentation instantanée du compteur de l'unité de temps correspondante.  [0004] Elastic means are provided for applying the spout permanently against the periphery of the cam, thus the lever pivots while the spout follows the rising profile of a sawtooth of the cam, before falling when the spout is found next to the radial face of this same tooth. The falling of the nose, and therefore the return of the lever in its position closest to the cam, causes an instantaneous incrementation of the counter of the corresponding unit of time.
[0005] Cependant, la Demanderesse expose elle-même, dans la description de la demande, un inconvénient de ce type de mécanisme, à savoir le fait que la came ne peut être entraînée que dans un seul sens de rotation, étant donné l'orientation de ses dents. Ainsi, ce document prévoit un dispositif de correction de l'heure courante agencé de manière à prévenir toute rotation de la came dans le mauvais sens de rotation. Plus précisément, ce dispositif de correction permet de modifier l'heure courante sans faire intervenir les leviers.  However, the Applicant discloses itself, in the description of the application, a disadvantage of this type of mechanism, namely the fact that the cam can be driven in only one direction of rotation, given the orientation of his teeth. Thus, this document provides a device for correcting the current time arranged so as to prevent any rotation of the cam in the wrong direction of rotation. More precisely, this correction device makes it possible to modify the current time without involving the levers.
[0006] Toutefois, la mise en œuvre d'un tel dispositif de correction n'est pas toujours souhaitable, en particulier lorsque l'information à afficher présente un nombre plus important de valeurs possibles, comme par exemple le quantième. On notera également que l'affichage de certaines informations, comme le quantième par exemple, est généralement commandé à partir des mêmes moyens qui commandent l'affichage de l'heure courante. Dans ce cas, une correction manuelle de l'heure courante peut donner lieu à des dommages au niveau du mécanisme d'entraînement instantané de cette information.  However, the implementation of such a correction device is not always desirable, especially when the information to be displayed has a larger number of possible values, such as the date. Note also that the display of certain information, such as the calendar for example, is generally controlled from the same means that control the display of the current time. In this case, manual correction of the current time may result in damage to the instant drive mechanism of this information.
[0007] Le brevet EP 1918792 B1 divulgue un mécanisme correcteur associé à un mécanisme d'entraînement similaire et, permettant de corriger la valeur d'une indication temporelle aussi bien en avant qu'en arrière. Dans ce but, ce mécanisme correcteur comporte une bascule de rappel, agencée à proximité du levier coopérant avec la came pour commander l'affichage de l'indication temporelle, dans le même plan, pour soulever le levier par l'intermédiaire d'un renvoi et placer son bec hors de portée de la périphérie de la came, lorsqu'une correction en arrière est opérée. EP 1918792 B1 discloses a correction mechanism associated with a similar drive mechanism and, to correct the value of a time indication both forward and backward. For this purpose, this correction mechanism comprises a return lever, arranged near the lever cooperating with the cam to control the display of the time indication, in the same plane, to lift the lever by through a return and place its spout out of range of the periphery of the cam, when a correction back is operated.
Divulgation de l'invention Disclosure of the invention
[0008] Un but principal de la présente invention est de proposer une alternative a ux mouvements horlogers connus présentant un mécanisme de commande d'un affichage sautant instantané, en proposant un tel mécanisme dans lequel à la fois la came avec laquelle coopère le levier peut être entraînée dans les deux sens de rotation, pour prévenir tout dommage lors de corrections manuelles, et présentant un encombrement limité dans le plan du mouvement horloger correspondant.  [0008] A main object of the present invention is to propose an alternative to known watch movements having a mechanism for controlling an instantaneous jumping display, by proposing such a mechanism in which both the cam with which the lever cooperates can be driven in both directions of rotation, to prevent damage during manual corrections, and having a limited footprint in the plane of the corresponding watch movement.
[0009] A cet effet, la présente invention concerne plus particulièrement un mécanisme d'entraînement instantané du type mentionné plus haut, caractérisé par le fait que le mobile comprend un organe de sécurité, coaxial à la roue d'entraînement et, agencé pour coopérer avec le levier pour éloigner le premier bras du centre du mobile lorsque ce dernier tourne dans le second sens de rotation et permettre au bec de passer du point correspondant au rayon le plus faible vers le point correspondant au plus grand rayon.  For this purpose, the present invention relates more particularly to an instantaneous drive mechanism of the type mentioned above, characterized in that the mobile comprises a safety member, coaxial with the drive wheel and arranged to cooperate. with the lever to move the first arm from the center of the mobile when the latter rotates in the second direction of rotation and allow the nozzle to pass from the point corresponding to the smallest radius to the point corresponding to the largest radius.
[0010] Grâce à ces caractéristiques, le mécanisme d'entraînement selon l'invention permet d'effectuer des corrections rapides de l'information à afficher ou d'une autre information qui lui est liée, notamment en permettant une rotation dans les deux sens de la came commandant les impulsions transmises par le levier au premier compteur.  Thanks to these features, the drive mechanism according to the invention makes it possible to make rapid corrections of the information to be displayed or other information related thereto, in particular by allowing rotation in both directions. the cam controlling the pulses transmitted by the lever to the first counter.
[001 1] De manière préférée, l'organe de sécurité présente une liaison cinématique avec la première came telle qu'ils sont mobiles angulairement l'un par rapport à l'autre entre des prem ière et seconde positions angulaires relatives. Une première de ces positions angulaires relatives est associée au premier sens de rotation tandis que le bec coopère avec la came pour définir la position du levier. Au moins une autre position est associée au second sens de rotation tandis que l'organe de sécurité coopère avec le levier pour définir la position de ce dernier.  [001 1] Preferably, the safety member has a kinematic connection with the first cam as they are angularly movable relative to each other between first and second relative angular positions. A first of these relative angular positions is associated with the first direction of rotation while the spout cooperates with the cam to define the position of the lever. At least one other position is associated with the second direction of rotation while the safety member cooperates with the lever to define the position of the latter.
[0012] Plus précisément, l'organe de sécurité peut comporter une planche, coaxiale à la première came et, présentant une pente à sa périphérie, inclinée par rapport à la direction radiale et s'étendant entre des points correspondant respectivement au rayon le plus faible et au rayon le plus grand de la planche. Dans ce cas, la planche et la première came sont avantageusement rendues solidaires l'une de l'autre en rotation par l'intermédiaire d'un organe élastique agencé de manière à permettre leur mobilité angulaire relative entre les première et seconde positions. More specifically, the safety member may comprise a board, coaxial with the first cam and, having a slope at its periphery, inclined relative to the radial direction and extending between points respectively corresponding to the smallest radius and the largest radius of the board. In this case, the board and the first cam are advantageously made integral with each other in rotation by means of an elastic member arranged to allow their relative angular mobility between the first and second positions.
[0013] On peut alors avantageusement prévoir que le mobile comporte une goupille solidaire de l'un des éléments parmi la première came et l'organe de sécurité, et dont une portion est agencée dans une fente, de longueur prédéfinie, ménagée dans l'autre des éléments pour définir les deux positions angulaires relatives. Le mobile peut en outre comporter un organe élastique présentant une base solidaire en rotation de celui des éléments comportant la fente et un doigt agencé pour coopérer avec la goupille pour tendre à positionner la première came et l'organe de sécurité en direction de la première position angulaire relative. It can then be advantageously provided that the mobile has a pin integral with one of the first cam and the safety member, and a portion of which is arranged in a slot, of predefined length, formed in the other elements to define the two relative angular positions. The mobile may further comprise an elastic member having a base integral in rotation with that of the elements comprising the slot and a finger arranged to cooperate with the pin to tend to position the first cam and the safety member in the direction of the first position relative angular.
[0014] Grâce aux caractéristiques qui précèdent, la came et l'organe de sécurité sont commandés l'un relativement à l'autre, en fonction du sens de rotation du mobile, de telle manière que celui de ces deux éléments capable d'écarter le levier agit sur ce dernier si nécessaire.  With the above characteristics, the cam and the safety member are controlled relative to each other, depending on the direction of rotation of the mobile, such that the one of these two elements capable of spreading the lever acts on the latter if necessary.
[0015] Selon un premier m ode de réalisation préféré, le levier comporte un premier doigt rétractable agencé pour agir au moins indirectement sur le premier compteur et lui transmettre les impulsions, le levier comportant en outre un dispositif de rétractation commandé par le mobile et agencé pour agir sur le premier doigt rétractable et, d'une part, le déplacer de telle manière qu'il est situé hors de portée du premier compteur pendant la phase au cours de laquelle le premier bras du levier est éloigné du centre du mobile et, d'autre part, le libérer préalablement à la chute du levier de telle manière qu'il peut transmettre une impulsion au premier compteur. [0015] According to a first preferred embodiment, the lever comprises a first retractable finger arranged to act at least indirectly on the first counter and transmit the pulses thereto, the lever further comprising a retraction device controlled by the mobile and arranged to act on the first retractable finger and, on the one hand, to move it so that it is located out of reach of the first counter during the phase during which the first arm of the lever is remote from the center of the mobile and, on the other hand, to release it before the fall of the lever so that it can transmit a pulse to the first counter.
[0016] De manière avantageuse, le dispositif de rétractation peut comporter un palpeur monté pivotant sur le levier et agencé pour coopérer, d'une part, avec la périphérie de la planche de l'organe de sécurité, cel le-ci présentant un rayon croissant depuis le point de rayon le plus faible jusqu'au point de rayon le plus grand, et, d'autre part, au moins indirectement avec le doigt rétractable. Advantageously, the retraction device may comprise a feeler pivotally mounted on the lever and arranged to cooperate, on the one hand, with the periphery of the board of the safety member, the latter having a radius growing from the lowest radius point to the point of greatest radius, and, secondly, at least indirectly with the retractable finger.
[0017] Grâce à ces caractéristiques, le doigt actionnant le compteur n'entre pas au contact de ce dernier lors de la phase au cours de laquelle il se positionne en amont par rapport à celui-ci, préservant ainsi la bonne marche du mouvement horloger correspondant. With these features, the finger actuating the counter does not come into contact with the latter during the phase during which it is positioned upstream with respect thereto, thus preserving the smooth running of the watch movement. corresponding.
[0018] Selon un second mode de réalisation préféré, le doigt rétractable peut être solidaire d'un organe de guidage agencé pour coopérer avec une goupille fixe, en particulier logée dans un élément de bâti du mouvement horloger correspondant. Dans ce cas, la coopération de l'organe de guidage avec la goupille présente un chemin prédéfini en fonction des déplacements du levier. Ce dernier comporte en outre un organe élastique agencé pour définir une position au repos de l'organe de guidage en référence au levier et, exerçant sur lui une force contribuant à définir le chemin prédéfini. According to a second preferred embodiment, the retractable finger can be integral with a guide member arranged to cooperate with a fixed pin, in particular housed in a frame member of the corresponding clock movement. In this case, the cooperation of the guiding member with the pin has a predefined path as a function of the movements of the lever. The latter further comprises an elastic member arranged to define a position at rest of the guide member with reference to the lever and exerting on it a force contributing to define the predefined path.
[0019] Le mécanisme selon l'invention peut avantageusement être mis en œuvre pour incrémenter, de manière instantanée, un second compteur du mouvement horloger. Ainsi, on peut prévoir que le levier comporte un second bras agencé pour coopérer avec le second compteur du mouvement horloger, dans le but de l'incrémenter au moyen d'impulsions instantanées sensiblement simultanées à celles agissant sur le premier compteur. The mechanism according to the invention may advantageously be implemented to increment, instantaneously, a second counter of the watch movement. Thus, it can be provided that the lever comprises a second arm arranged to cooperate with the second counter of the watch movement, in order to increment it by means of instantaneous pulses substantially simultaneous with those acting on the first counter.
[0020] Dans ce cas, le levier peut comporter un second doigt rétractable agencé pour agir au moins indirectement sur le second compteur et lui transmettre les impulsions, le dispositif de rétractation étant agencé pour agir également sur le second doigt et, d'une part, le déplacer de telle manière qu'il est situé hors de portée du second compteur pendant la phase au cours de laquelle le premier bras du levier est éloigné du centre du mobile et, d'autre part, le libérer préalablement à la chute du levier de telle manière qu'il peut transmettre une impulsion au second compteur.  In this case, the lever may comprise a second retractable finger arranged to act at least indirectly on the second counter and transmit the pulses thereto, the retraction device being arranged to act also on the second finger and, on the one hand , moving it such that it is located out of range of the second counter during the phase during which the first arm of the lever is away from the center of the mobile and, secondly, release it before the fall of the lever in such a way that it can transmit a pulse to the second counter.
[0021 ] Le dispositif de rétractation peut également comporter une bascule montée pivotante sur le levier et, présentant des première et seconde extrémités agencées pour coopérer respectivement avec les premier et second doigts rétractables. Ainsi, la rétractation de l'un des doigts entraîne celle de l'autre. The retraction device may also comprise a pivotally mounted rocker on the lever and, having first and second ends arranged to cooperate respectively with the first and second second retractable fingers. Thus, the retraction of one of the fingers causes that of the other.
[0022] On pourra par exemple mettre en œuvre le mécanisme selon la présente invention pour commander simultanément des affichages par sauts instantanés du quantième et du jour de la semaine.  For example, it is possible to implement the mechanism according to the present invention to simultaneously control instantaneous jump displays of the date and the day of the week.

Mode(s) de réalisation de l'invention Mode (s) of realization of the invention
[0037] La figure 1 représente une vue de face simplifiée d'un mécanisme d'entraînement instantané pour mouvement horloger selon un premier mode de réalisation préféré de la présente invention. Plus précisément, le mécanisme représenté est destiné à commander l'affichage du quantième, sous forme de grande date, ainsi que du jour de la semaine.  FIG. 1 represents a simplified front view of an instantaneous drive mechanism for a watch movement according to a first preferred embodiment of the present invention. More precisely, the mechanism represented is intended to control the display of the date, in the form of a big date, as well as the day of the week.
[0038] A cet effet, le mécanisme comporte un rouage de finissage, reliant une base de temps à un organe moteur conventionnels (non représentés) et, entraînant une roue des heures 1 en rotation, à raison d'un tour complet toutes les 12 heures, à titre indicatif non limitatif.  For this purpose, the mechanism comprises a finishing gear, connecting a time base to a conventional motor (not shown) and driving a wheel 1 hours in rotation, due to a complete turn every 12 hours, as a non-restrictive indicative.
[0039] La roue des heures 1 est reliée cinématiquement à un mobile 2 du mécanisme d'entraînement selon l'invention par l'intermédiaire d'un jeu de renvois 3, agencé en prise avec une première roue dentée 4 du mobile 2, de telle manière que cette dernière effectue un tour complet sur elle-même en 24 heures. The hour wheel 1 is kinematically connected to a mobile 2 of the drive mechanism according to the invention via a set of references 3, arranged in engagement with a first gear 4 of the mobile 2, of so that it performs a complete turn on itself in 24 hours.
[0040] Le mobile 2 coopère avec un levier 6, d'une manière qui sera décrite en détail plus loin, pour incrémenter, instantanément et de manière sensiblement simultanée, les compteurs du quantième et du jour de la semaine toutes les 24 heures. [0041] Le levier 6 comporte un premier bras 7 destiné à incrémenter un premier compteur des jours de la semaine 8 en transmettant des impulsions à un pignon 9, à sept dents, solidaire d'un disque 10 d'affichage des jours de la semaine. The mobile 2 cooperates with a lever 6, in a manner to be described in detail later, to increment, instantly and substantially simultaneously, the date and weekday meters every 24 hours. The lever 6 comprises a first arm 7 for incrementing a first counter days of the week 8 by transmitting pulses to a pinion 9, seven teeth, secured to a display disk 10 days of the week .
[0042] Le levier 6 comporte par ailleurs un second bras 12 destiné à incrémenter un second compteur de quantième 13 en transmettant des impulsions à une roue 14 de commande à deux étages, destinée à commander les déplacements de deux pignons 15 et 16, respectivement solidaires de disques des unités et des dizaines de quantième, pour réaliser un affichage de type grande date conventionnel.  The lever 6 further comprises a second arm 12 for incrementing a second date counter 13 by transmitting pulses to a two-stage control wheel 14 for controlling the movements of two pinions 15 and 16, respectively integral. of units and dozens of date disks, to achieve a conventional large date type display.
[0043] Des ressorts sautoirs 18, 19, 20 et 21 sont prévus, de manière connue, pour assurer un bon positionnement angulaire des disques et de la roue de commande.  Jumper springs 18, 19, 20 and 21 are provided, in known manner, to ensure good angular positioning of the discs and the control wheel.
[0044] On notera également qu'un ressort 22 est formé intégralement avec le levier 6 pour assurer sa bonne coopération avec le mobile 2. Ce ressort 22 est disposé en appui contre une came 24, maintenue sur un élément de bâti du mouvement horloger au moyen d'une vis 25. La périphérie de la came 24 présente une succession de segments plus ou moins distants du centre de la came. La précontrainte que présente le ressort 22 peut ainsi être ajustée en fonction du segment contre lequel il est disposé en appui.  Note also that a spring 22 is formed integrally with the lever 6 to ensure good cooperation with the mobile 2. This spring 22 is disposed in abutment against a cam 24, held on a frame member of the watch movement at by means of a screw 25. The periphery of the cam 24 has a succession of segments more or less distant from the center of the cam. The prestressing of the spring 22 can thus be adjusted according to the segment against which it is placed in support.
[0045] La figure 2 représente une vue en perspective éclatée du mobile 2 selon un premier mode de réalisation préféré de la présente invention.  [0045] Figure 2 shows an exploded perspective view of the mobile 2 according to a first preferred embodiment of the present invention.
[0046] La première roue dentée 4 est solidaire d'un canon 27 sur lequel sont engagés une came 28, un organe élastique 29 et une planche de retenue 30. L'axe central creux du canon est destiné à être engagé sur un tenon porté par un élément de bâti du mouvement horloger pour y monter le mobile à pivot.  The first toothed wheel 4 is secured to a barrel 27 on which are engaged a cam 28, an elastic member 29 and a retaining board 30. The hollow central axis of the barrel is intended to be engaged on a post carried by a frame member of the watch movement to mount the pivotal mobile.
[0047] Le canon 27 présente un méplat 32 avec lequel coopèrent des ouvertures 33, 34 de forme complémentaire ménagées dans l'organe élastique 29 et la planche de retenue 30. Par cette coopération, le canon 27, l'organe élastique 29 et la planche de retenue 30 sont solidaires en rotation. [0048] Par ailleurs, le canon 27 présente un épaulement 36 définissant une surface de guidage radial pour la came 28, montée sur le canon en étant libre de tourner par rapport à ce dernier. The barrel 27 has a flat 32 with which cooperate openings 33, 34 of complementary shape formed in the elastic member 29 and the retaining plate 30. By this cooperation, the barrel 27, the elastic member 29 and the retaining board 30 are integral in rotation. In addition, the barrel 27 has a shoulder 36 defining a radial guide surface for the cam 28, mounted on the barrel being free to rotate relative to the latter.
[0049] Le canon 27 porte également un organe de sécurité 38 dont le fonctionnement sera exposé plus loin. L'organe de sécurité est solidaire du canon, et donc de la roue dentée 4, en rotation.  The barrel 27 also carries a safety member 38 whose operation will be explained later. The safety member is secured to the barrel, and therefore the toothed wheel 4, in rotation.
[0050] L'organe de sécurité comporte une planche dont la périphérie présente un rayon variable, plus précisément ici, dont le rayon croît sensiblement continûment entre un rayon le plus faible et un rayon le plus grand. Une pente inclinée 39 par rapport à la direction radiale définit la jonction entre les points de rayon le plus faible et le plus grand. L'organe de sécurité comprend par ailleurs une fente 40 s'étend sensiblement suivant une trajectoire circulaire.  The safety member comprises a board whose periphery has a variable radius, more precisely here, whose radius increases substantially continuously between a smallest radius and a largest radius. An inclined slope 39 relative to the radial direction defines the junction between the points of the smallest radius and the largest. The safety member further comprises a slot 40 extending substantially in a circular path.
[0051] La came 28 vient se positionner sur le canon 27 en étant adjacente à l'organe de sécurité 38. Elle présente également une périphérie de rayon variable, plus précisément ici, en ayant son rayon qui croît sensiblement continûment entre un rayon le plus faible et un rayon le plus grand. La jonction 42 entre les points de rayon le plus grand et de rayon le plus faible présente une courbure située entre la région de la périphérie correspondant aux rayons les plus importants et le centre de la came, de manière à définir une interruption brutale de la périphérie après le point de rayon le plus grand en direction du point de rayon le plus faible.  The cam 28 is positioned on the barrel 27 being adjacent to the safety member 38. It also has a periphery of variable radius, more precisely here, having its radius which increases substantially continuously between a radius most weak and a radius largest. The junction 42 between the points of largest radius and the smallest radius has a curvature located between the region of the periphery corresponding to the largest radii and the center of the cam, so as to define a sudden interruption of the periphery after the point of greatest radius towards the point of the weakest radius.
[0052] En outre, la came 28 porte une goupille 44 destinée à coopérer avec la fente 40 de l'organe de sécurité, comme cela sera exposé plus loin en détail.  In addition, the cam 28 carries a pin 44 for cooperating with the slot 40 of the safety member, as will be discussed further in detail.
[0053] L'organe élastique 29 comprend une base 45 permettant d'assurer sa tenue sur le canon 27 et à partir de laquelle s'étendent un anneau périphérique 46 et un bras élastique 47, de forme générale sensiblement circulaire. Ce dernier présente deux doigts en formes de griffes 48, 49 orientées en regard l'une de l'autre, à son extrémité libre destinée à coopérer avec la goupille 44 portée par la came 28, pour tendre à la déplacer dans un sens ou dans l'autre à l'intérieur de la fente 40. Lorsque le mobile 2 est assemblé et ne subit pas de contrainte externe, la goupille 44 est libre de se positionner entre les deux griffes 48 et 49. The elastic member 29 comprises a base 45 to ensure its holding on the barrel 27 and from which extend a peripheral ring 46 and an elastic arm 47, of generally circular shape. The latter has two fingers in the form of claws 48, 49 oriented facing each other, at its free end intended to cooperate with the pin 44 carried by the cam 28, to tend to move in one direction or in the other inside the slot 40. When the mobile 2 is assembled and does not undergo external stress, the pin 44 is free to position between the two claws 48 and 49.
[0054] La planche de retenue 30 présente la forme générale d'un anneau et comporte deux fenêtres 51 , 52 dont la présence est purement illustrative, leur fonction étant de permettre la visualisation d'un détail du mécanisme selon l'invention en cours de fonctionnement. La fonction principale de la planche de retenue est d'assurer que le bras élastique 47 ne se déforme pas en dehors de son plan de travail.  The retaining board 30 has the general shape of a ring and comprises two windows 51, 52 whose presence is purely illustrative, their function being to allow the visualization of a detail of the mechanism according to the invention in progress. operation. The main function of the retaining board is to ensure that the elastic arm 47 does not deform outside its worktop.
[0055] Les figures 3a et 3b représentent des vues en perspective des première et seconde faces du levier 6 destiné à coopérer avec le mobile 2 qui vient d'être décrit.  Figures 3a and 3b show perspective views of the first and second faces of the lever 6 for cooperating with the mobile 2 which has just been described.
[0056] Le levier 6 comporte un alésage 60 destiné à permettre sa fixation à pivot sur un élément de bâti du mouvement horloger.  The lever 6 comprises a bore 60 intended to allow its attachment to pivot on a frame member of the watch movement.
[0057] Le premier bras 7 comprend, à proximité de son extrémité libre, un premier bec 61 destiné à coopérer avec la périphérie de la came 28, suivi d'un second bec 62 définissant une première surface de butée pour un premier doigt rétractable 63, monté pivotant sur le premier bras 7 et agencé pour transmettre des impulsions au pignon 9 du compteur des jours de la semaine 8. Une seconde surface de butée 64 est ménagée pour définir une plage de débattement du premier doigt rétractable. Un ressort 65, formé ici d'une pièce avec le levier 6 est prévu pour appliquer une force sur le premier doigt rétractable, par l'intermédiaire d'une extension 66, tendant à le maintenir en butée contre la seconde surface de butée 64.  The first arm 7 comprises, near its free end, a first spout 61 intended to cooperate with the periphery of the cam 28, followed by a second spout 62 defining a first abutment surface for a first retractable finger 63 , pivotally mounted on the first arm 7 and arranged to transmit pulses to the pinion 9 of the day of the week counter 8. A second stop surface 64 is provided to define a range of movement of the first retractable finger. A spring 65, here formed in one piece with the lever 6 is provided for applying a force on the first retractable finger, via an extension 66, tending to hold it against the second abutment surface 64.
[0058] Par ailleurs, le premier bras 7 porte également un palpeur 68 destiné à coopérer avec la périphérie de l'organe de sécurité 38 et, monté pivotant sur le premier bras.  Furthermore, the first arm 7 also carries a probe 68 for cooperating with the periphery of the safety member 38 and pivotally mounted on the first arm.
[0059] Le levier 6 porte une bascule 70, montée en rotation sur le levier, avec un axe de rotation coaxial à l'alésage 60 et, présentant des premier et second bras 71 , 72 respectivement superposés aux premier et second bras du levier 7, 12.  The lever 6 carries a latch 70 mounted in rotation on the lever, with an axis of rotation coaxial with the bore 60 and having first and second arms 71, 72 respectively superimposed on the first and second arms of the lever 7 , 12.
[0060] L'extrémité libre du premier bras 71 de la bascule est agencée à proximité du palpeur 68 et présente une portion pliée 69 agencée en butée contre l'arrière du palpeur 68, de telle manière que ce dernier entraîne un pivotement de la bascule, simultanément à un pivotement du premier doigt rétractable 63, lorsqu'il pivote. En effet, la portion pliée est agencée de telle manière qu'elle peut exercer sur l'extension 66 une force antagoniste à celle du ressort 65, pour écarter le premier doigt rétractable de la seconde surface de butée 64. L'extrémité libre du second bras 72 de la bascule coopère avec un second doigt rétractable 74 pour le faire pivoter sensiblement simultanément au premier doigt rétractable 63. Des première et seconde surfaces de butée 75, 76 sont ménagées dans le second bras 12 pour limiter la course du second doigt rétractable 74 dans les deux sens de rotation. The free end of the first arm 71 of the rocker is arranged near the sensor 68 and has a folded portion 69 arranged in abutment against the back of the probe 68, so that the latter causes a pivoting of the rocker, simultaneously with a pivoting of the first retractable finger 63 when it pivots. Indeed, the folded portion is arranged in such a way that it can exert on the extension 66 a force that is antagonistic to that of the spring 65, to separate the first retractable finger from the second abutment surface 64. The free end of the second arm 72 of the rocker cooperates with a second retractable finger 74 to pivot substantially simultaneously to the first retractable finger 63. First and second abutment surfaces 75, 76 are formed in the second arm 12 to limit the stroke of the second retractable finger 74 in both directions of rotation.
[0061] On notera également qu'une surface de butée supplémentaire 77 est ménagée sur le premier bras 7 du levier pour limiter la course du palpeur 68. It will also be noted that an additional abutment surface 77 is provided on the first arm 7 of the lever to limit the stroke of the probe 68.
[0062] Les figures 4a à 4d représentent la cinématique de fonctionnement du mécanisme d'entraînement instantané selon le premier mode de réalisation de la présente invention, dans un premier sens de rotation, dans une même vue de face simplifiée, similaire à celle de la figure 1. Plus précisément, le premier sens de rotation est ici le sens de fonctionnement normal du mécanisme, c'est-à-dire notamment lorsqu'il est entraîné par le rouage de finissage. Dans un tel mode de fonctionnement, la roue des heures 1 tourne dans le sens de rotation horaire sur les figures 4a à 4d, ce qui correspond à une rotation du mobile 2 dans le sens de rotation antihoraire.  FIGS. 4a to 4d show the operating kinematics of the instantaneous driving mechanism according to the first embodiment of the present invention, in a first direction of rotation, in the same simplified front view, similar to that of the Figure 1. More specifically, the first direction of rotation is here the normal operating direction of the mechanism, that is to say, especially when it is driven by the gear train. In such an operating mode, the hours wheel 1 rotates in the clockwise rotation direction in FIGS. 4a to 4d, which corresponds to a rotation of the mobile 2 in the anticlockwise rotation direction.
[0063] Partant du rayon le plus faible de la périphérie de la came 28, associé à une heure située immédiatement après minuit d'un jour donné (figure 4d), le bec 61 suit, pendant près de 24 heures, la périphérie de la came 28 jusqu'à la position illustrée sur la figure 4a, qui correspond à une heure juste après minuit, le jour suivant. En effet, la roue 4 étant entraînée dans le sens de rotation anti-horaire, elle entraîne la came 28 dans le même sens par coopération de sa fente 40 avec la goupille 44 portée par la came 28. [0064] Le rayon de la périphérie de la came 28 augmentant progressivement, le levier pivote lentement dans le sens horaire dans le même temps, de telle manière que son premier bras 7 s'éloigne progressivement du centre de la came 28. Starting from the smallest radius of the periphery of the cam 28, associated with a time immediately after midnight of a given day (FIG. 4d), the spout 61 follows, for nearly 24 hours, the periphery of the cam 28 to the position shown in Figure 4a, which corresponds to one hour just after midnight, the next day. Indeed, the wheel 4 being driven in the direction of rotation anti-clockwise, it drives the cam 28 in the same direction by cooperation of its slot 40 with the pin 44 carried by the cam 28. The radius of the periphery of the cam 28 increasing gradually, the lever slowly pivots in the clockwise direction at the same time, so that its first arm 7 moves progressively away from the center of the cam 28.
[0065] Encore dans le même temps, le palpeur 68 suit la périphérie de l'organe de sécurité 38 dont le rayon, partant de sa valeur sensiblement la plus faible augmente progressivement jusqu'à sa valeur la plus grande, tel qu'illustré sur la figure 4a. At the same time, the feeler 68 follows the periphery of the safety member 38 whose radius, starting from its substantially lower value, progressively increases to its largest value, as illustrated on FIG. Figure 4a.
[0066] Le ressort 22 agissant sur le premier bras 7 du levier pour maintenir le bec 61 contre la périphérie de la came 28, l'augmentation du rayon de la périphérie de l'organe de sécurité entraîne le pivotement progressif du palpeur 68. En effet, les forces relatives des ressorts 22 et 65 sont avantageusement choisies de telle manière que l'action du ressort 22 prédomine sur celle du ressort 65. The spring 22 acting on the first arm 7 of the lever to maintain the spout 61 against the periphery of the cam 28, the increase of the radius of the periphery of the safety member causes the progressive pivoting of the probe 68. Indeed, the relative forces of the springs 22 and 65 are advantageously chosen in such a way that the action of the spring 22 predominates over that of the spring 65.
[0067] Ainsi, lors de la rotation du mobile 2 qui l'a conduit dans sa position de la figure 4a, le pivotement du palpeur 68 a entraîné une rétractation des premier et second doigts rétractables 63 et 74. La pente de croissance du rayon de l'organe de sécurité est choisie de telle manière que les deux doigts rétractables sont suffisamment rétractés pour être hors de portée des compteurs 8 et 13 lorsqu'ils passent devant les dents respectives auxquelles ils vont transmettre la prochaine impulsion. Grâce à une telle précaution, la bonne marche du mouvement horloger n'est pas perturbée par un éventuel contact qui aurait pu intervenir autrement entre chaque doigt rétractable et une dent du mobile avec lequel il coopère. Thus, during the rotation of the mobile 2 which led to its position in Figure 4a, the pivoting of the probe 68 has resulted in a retraction of the first and second retractable fingers 63 and 74. The slope of growth of the radius of the safety member is chosen such that the two retractable fingers are sufficiently retracted to be out of range of the counters 8 and 13 as they pass in front of the respective teeth to which they will transmit the next pulse. With such a precaution, the smooth running of the watch movement is not disturbed by a possible contact that could have occurred otherwise between each retractable finger and a tooth of the mobile with which it cooperates.
[0068] Da ns l a co nfi g u rati o n d e l a fi g u re 4a , l es d o i gts 63 et 74 so nt complètement rétractés, le palpeur étant en appui contre le point de la périphérie de l'organe de sécurité présentant le rayon le plus grand. In the case of FIG. 4a, the fingers 63 and 74 are completely retracted, the probe being in abutment against the point of the periphery of the safety member having the largest radius. great.
[0069] Passant à la configuration de la figure 4b, tandis que le bec 61 poursuit sa course le long de la périphérie de la came 28, le palpeur 68 dépasse le point de rayon le plus grand de l'organe de sécurité et atteint la pente 39 de ce dernier. A cet instant, le palpeur 68 ne subit plus de contrainte hormis celle du ressort 65 qui le fait pivoter contre sa surface de butée 77. [0070] Dans le même temps, les deux doigts rétractables 63 et 74 quittent leur position rétractée en tournant dans le sens horaire sur la figure 4b, pour se préparer à transmettre chacun une impulsion au compteur correspondant. Moving to the configuration of Figure 4b, while the spout 61 continues its stroke along the periphery of the cam 28, the probe 68 exceeds the largest radius point of the safety member and reaches the slope 39 of the latter. At this moment, the probe 68 is no longer constrained except that of the spring 65 which pivots it against its abutment surface 77. At the same time, the two retractable fingers 63 and 74 leave their retracted position by turning clockwise in Figure 4b, to prepare to transmit each pulse to the corresponding counter.
[0071 ] Lorsqu'un peu plus tard, sensiblement à minuit, le bec 61 franchit le point de rayon le plus grand de la périphérie de la came 28, le levier 6 pivote rapidement dans le sens de rotation anti-horaire, sous l'effet de l'action du ressort 22, ce qui est illustré sur la figure 4c. Dans le même temps, chacun des deux doigts rétractables 63 et 74 entre en contact avec une dent du mobile de compteur correspondant pour le faire tourner d'un pas et incrémenter le compteur. When a little later, substantially at midnight, the spout 61 crosses the largest radius point of the periphery of the cam 28, the lever 6 pivots rapidly in the direction of rotation anti-clockwise, under the effect of the action of the spring 22, which is illustrated in Figure 4c. At the same time, each of the two retractable fingers 63 and 74 comes into contact with a tooth of the corresponding counter mobile to rotate it one step and increment the counter.
[0072] La figure 4d illustre la configuration du mécanisme d'entraînement instantané selon la présente invention immédiatement après minuit, soit immédiatement après la chute du levier 6 au niveau de la jonction 42 de la périphérie de la came 28. A cet instant, chacun des compteurs de quantième et des jours de la semaine a été incrémenté. FIG. 4d illustrates the configuration of the instantaneous drive mechanism according to the present invention immediately after midnight, ie immediately after the fall of the lever 6 at the junction 42 of the periphery of the cam 28. At this instant, each date counters and days of the week have been incremented.
[0073] Considérant maintenant le cas de figure selon lequel l'utilisateur d'une pièce d'horlogerie incorporant le mécanisme d'entraînement selon la présente invention souhaiterait procéder à une correction des informations affichées. Dans le cas d'une correction du quantième ou du jour de la semaine, un mécanisme de correction rapide spécifique est prévu et sera décrit plus loin. Dans le cas d'une correction de l'heure courante, on notera que toute rotation manuelle, par l'utilisateur, de la roue des heures 1 entraîne également celle du mobile 2, par l'intermédiaire du jeu de renvois 3. Considering now the case in which the user of a timepiece incorporating the drive mechanism according to the present invention would make a correction of the information displayed. In the case of a correction of the date or the day of the week, a specific fast correction mechanism is provided and will be described later. In the case of a correction of the current time, it will be noted that any manual rotation by the user of the hour wheel 1 also causes that of the mobile 2, via the set of references 3.
[0074] Ainsi, l'opération de mise à l'heure peut potentiellement donner lieu à des dommages, si aucune mesure de sécurité n'est prise, lorsque la roue des heures 1 est entraînée dans le sens de rotation anti-horaire, du fait des formes respectives du bec 61 et de la came 28.  Thus, the time setting operation can potentially give rise to damage, if no safety measure is taken, when the hour wheel 1 is driven in the anti-clockwise direction of the rotation. makes respective shapes of the spout 61 and the cam 28.
[0075] Une telle situation ressort de la configuration illustrée sur la figure 4d. Si la roue des heures est entraînée dans le sens de rotation anti-horaire à partir de la position illustrée sur cette figure, impliquant une rotation dans le sens horaire du mobile 2, la jonction 42 de la came 28 vient se positionner en butée contre le bec 61 du levier 6. L'orientation de l'interface de contact entre la jonction 42 et le bec 61 est telle que ce dernier ne peut s'écarter de la came pour permettre à la came de poursuivre sa rotation. Such a situation is apparent from the configuration illustrated in Figure 4d. If the hour wheel is driven in the anti-clockwise direction from the position illustrated in this figure, involving a rotation in the clockwise direction of the mobile 2, the junction 42 of the cam 28 is positioned in position. stop against the spout 61 of the lever 6. The orientation of the contact interface between the junction 42 and the spout 61 is such that the latter can not deviate from the cam to allow the cam to continue its rotation.
[0076] Les figures 5a à 5e illustrent le fonctionnement de l'organe de sécurité 38 en relation avec le levier 6 pour éviter que des dommages ne soient causés au mécanisme d'entraînement instantané dans un tel cas de figure. Figures 5a to 5e illustrate the operation of the safety member 38 in relation to the lever 6 to prevent damage to the instantaneous drive mechanism in such a case.
[0077] Lorsque, partant de la configuration de la figure 4d, la roue dentée 4 tourne dans le sens de rotation horaire, la jonction 42 de la came 28 bute contre le bec 61 qui bloque donc la came.  When, starting from the configuration of Figure 4d, the toothed wheel 4 rotates in the clockwise direction, the junction 42 of the cam 28 abuts against the nose 61 which therefore blocks the cam.
[0078] Toutefois, la roue dentée 4 peut continuer sa course par déplacement de la goupille 44 à l'intérieur de la fente 40 ménagée dans l'organe de sécurité 38, ce qui est visible sur la figure 5a, la came 28 restant immobile.  However, the toothed wheel 4 can continue its travel by moving the pin 44 inside the slot 40 formed in the safety member 38, which is visible in Figure 5a, the cam 28 remaining stationary .
[0079] Dans le même temps, le palpeur 68 entre en contact avec la pente 39 de l'organe de sécurité, dans une position verrouillée contre sa surface de butée 77. La rotation de l'organe de sécurité 38 entraîne ainsi un glissement du palpeur 68 le long de la pente 39, provoquant un soulèvement du premier bras 7 du levier 6 par rapport au mobile 2.  At the same time, the probe 68 comes into contact with the slope 39 of the safety member, in a locked position against its abutment surface 77. The rotation of the safety member 38 thus causes a sliding of the feeler 68 along the slope 39, causing a lifting of the first arm 7 of the lever 6 relative to the mobile 2.
[0080] A un certain stade, la pointe du bec 61 franchit l'arête définie entre la jonction 42 et le point de rayon le plus grand de la périphérie de la came 28 pour parvenir à la configuration illustrée sur la figure 5b.  At a certain stage, the tip of the spout 61 crosses the edge defined between the junction 42 and the largest radius point of the periphery of the cam 28 to achieve the configuration shown in Figure 5b.
[0081] Le palpeur 68 poursuivant sa course le long de la pente 39, il éloigne davantage le premier bras 7 du centre de la came 28 permettant ainsi au bec 61 de franchir l'arête susmentionnée pour présenter la configuration illustrée sur la figure 5c. On constate en comparant les configurations des figures 5b et 5c que la came a légèrement pivoté dans le sens horaire, sous l'effet de l'action du bras élastique 47 sur la goupille 44.  The probe 68 continues its course along the slope 39, it further moves the first arm 7 of the center of the cam 28 and the spout 61 to cross the aforementioned edge to present the configuration shown in Figure 5c. It can be seen by comparing the configurations of FIGS. 5b and 5c that the cam has slightly rotated clockwise, under the effect of the action of the elastic arm 47 on the pin 44.
[0082] De manière avantageuse, on peut prévoir que lorsque le palpeur 68 atteint le point de plus grand rayon de l'organe de sécurité 38, le bec 61 est hors de portée de la came 28, notamment dans le but de ménager une marge de sécurité, tel que cela ressort de la configuration illustrée sur la figure 5d. [0083] En outre, lorsque le palpeur dépasse ce point de plus grand rayon, la direction de la force qu'il subit par son contact avec la périphérie de l'organe de sécurité change d'orientation et provoque son pivotement, tel que cela apparaît sur la figure 5e. Ce pivotement permet au premier bras 7 du levier 6 de se rapprocher de la came 28 et de replacer le bec 61 en butée contre la périphérie de cette dernière. Advantageously, it can be provided that when the probe 68 reaches the point of greatest radius of the safety member 38, the spout 61 is out of reach of the cam 28, particularly in order to provide a margin as evidenced by the configuration illustrated in Figure 5d. In addition, when the probe exceeds this point of greater radius, the direction of the force that it undergoes by its contact with the periphery of the safety member changes orientation and causes its pivoting, such as that appears in Figure 5e. This pivoting allows the first arm 7 of the lever 6 to approach the cam 28 and to replace the spout 61 abutting against the periphery of the latter.
[0084] Au cours de cette opération, l'affichage de l'heure courante est passé d'une position indiquant une heure située peu après minuit à une heure située quelques heures avant minuit. During this operation, the display of the current time has changed from a position indicating a time located shortly after midnight to an hour located a few hours before midnight.
[0085] Ainsi, dès que le mécanisme d'entraînement se trouve dans la configuration de la figure 5e, l'utilisateur peut se mettre à tourner la roue des heures dans le sens normal, c'est-à-dire le sens de rotation horaire, pour faire repasser l'affichage de l'heure courante à une heure située après minuit. Dans ce cas, la première roue dentée 4 se remet à tourner dans le sens de rotation anti-horaire. Dans un premier temps, la came 28 reste sensiblement immobile, jusqu'à ce que la fente 40 vienne se repositionner en butée contre la goupille 44. Dans ce même temps, le palpeur 68 revient se positionner en regard de la pente 39 et pivote à nouveau dans le sens de rotation anti-horaire sur la figure 5e, de manière à replacer les doigts rétractables 63 et 74 à portée des dentures associées (dans une configuration proche de celle de la figure 4b, mis à part le positionnement relatif de la fente 40 et de la goupille 44). Thus, as soon as the drive mechanism is in the configuration of Figure 5e, the user can start turning the hour wheel in the normal direction, that is to say the direction of rotation time, to return the display of the current time to a time after midnight. In this case, the first gearwheel 4 is rotated in the anticlockwise rotation direction. In a first step, the cam 28 remains substantially stationary, until the slot 40 comes to reposition itself in abutment against the pin 44. At the same time, the feeler 68 returns to position itself facing the slope 39 and pivots to again in the anti-clockwise rotation direction in FIG. 5e, so as to replace the retractable fingers 63 and 74 within reach of the associated teeth (in a configuration similar to that of FIG. 4b, apart from the relative positioning of the slot 40 and pin 44).
[0086] Lorsque la fente 40 parvient en butée contre la goupille 44, la came 28 est à nouveau entraînée dans le sens de rotation anti-horaire à partir de la roue 4. Le bec 61 franchit alors rapidement le point de rayon le plus grand de la périphérie de la came 28 pour permettre la chute du levier, sous l'effet de l'action du ressort 22, et l'incrémentation des compteurs de quantième et du jour de la semaine, tel que précédemment décrit en relation avec les figures 4c et 4d. When the slot 40 abuts against the pin 44, the cam 28 is again driven in the direction of rotation anti-clockwise from the wheel 4. The spout 61 then quickly passes the point of greatest radius the periphery of the cam 28 to allow the fall of the lever, under the effect of the action of the spring 22, and the incrementation of the date and date of the week meters, as previously described in connection with the figures 4c and 4d.
[0087] Il ressort de ce qui précède que lors du fonctionnement courant du mécanisme d'entraînement selon la présente invention, la position du levier 6 relativement à la came 28 est définie par l'interaction entre le bec 61 et la périphérie de la came. Le mécanisme d'entraînement se comporte de manière similaire lorsque la roue des heures 1 est entraînée manuellement suivant le sens de rotation horaire. Toutefois, lorsque la roue des heures est entraînée manuellement dans le sens de rotation antihoraire, la came et le bec peuvent se retrouver en butée l'un contre l'autre conduisant au blocage de la came et, dans ce cas, l'interaction entre le palpeur 68 et la pente 39 de l'organe de sécurité 38 permet au bec 61 de surmonter la jonction 42, pour passer du point de rayon le plus faible de la périphérie de la came 28 à son point de rayon le plus grand, sans causer de dommage au mécanisme. It follows from the above that during the current operation of the drive mechanism according to the present invention, the position of the lever 6 relative to the cam 28 is defined by the interaction between the spout 61 and the periphery of the cam . The drive mechanism behaves similarly when the hour wheel 1 is driven manually in the clockwise direction. However, when the hour wheel is driven manually in the anticlockwise rotation direction, the cam and the nose may be in abutment with each other leading to cam locking and, in this case, the interaction between the feeler 68 and the slope 39 of the safety member 38 allows the spout 61 to overcome the junction 42, to move from the point of the smallest radius of the periphery of the cam 28 to its largest radius point, without cause damage to the mechanism.
[0088] On notera que le fonctionnement du mécanisme selon la présente invention permet de faciliter la mise en place des aiguilles pour un horloger chargé de l'assemblage d'une pièce d'horlogerie correspondante. En effet, la mise en place des aiguilles des heures et des minutes courantes est généralement effectuée lorsque la roue des heures et la chaussée sont disposées dans leur position correspondant à minuit, cette position étant repérable par le saut du compteur de quantième. Ainsi, avec un mécanisme tel que celui qui vient d'être décrit, l'horloger peut chercher grossièrement la position minuit en repérant le saut du levier 6 et mettre en place les aiguilles sans les chasser complètement, dans un premier temps. Il peut alors revenir en arrière en corrigeant manuellement l'heure courante puis changer de sens pour entraîner à nouveau le mécanisme dans le sens normal, de manière plus lente, pour détecter de manière plus précise la position minuit et chasser entièrement les aiguilles. Une telle procédure n'est pas envisageable avec les mécanismes de l'art antérieur qui exigent par conséquent plus de concentration et d'essais de la part de l'horloger en cours de mise en place des aiguilles, ce qui se traduit évidemment par des coûts d'assemblage supérieurs. En effet, pour repositionner le mouvement horloger dans sa configuration correspondant à minuit, l'horloger doit faire faire deux nouveaux tours complets à l'aiguille des heures courantes, avec les mécanismes de l'art antérieur, pour parvenir au même résultat.  Note that the operation of the mechanism according to the present invention facilitates the introduction of needles for a watchmaker responsible for assembling a corresponding timepiece. In fact, the setting of the current hour and minute hands is generally performed when the hour wheel and the roadway are arranged in their corresponding position at midnight, this position being detectable by the jump of the date counter. Thus, with a mechanism such as that just described, the watchmaker can roughly search the midnight position by identifying the leap of the lever 6 and set up the needles without completely chasing them, at first. He can then go back by manually correcting the current time and then changing direction to train the mechanism in the normal direction, more slowly, to more accurately detect the midnight position and completely chase the needles. Such a procedure can not be envisaged with the mechanisms of the prior art which consequently require more concentration and testing on the part of the watchmaker during the setting up of the needles, which obviously results in higher assembly costs. Indeed, to reposition the watch movement in its configuration corresponding to midnight, the watchmaker must make two new complete turns to the current hours hand, with the mechanisms of the prior art, to achieve the same result.
[0089] Les figures 6 et 7 représentent, dans des vues de face similaires et simplifiées, le fonctionnement d'un mécanisme de correction rapide du quantième et du jour de la semaine qui peut avantageusement être mis en œuvre en complément au mécanisme d'entraînement qui vient d'être décrit. Figures 6 and 7 show, in similar and simplified front views, the operation of a fast correction mechanism of the date and the day of the week which can advantageously be implemented in addition to the drive mechanism which has just been described.
[0090] Ce mécanisme de correction rapide comporte une bascule de correction 80 montée pivotante sur un élément de bâti du mouvement horloger, entre au moins une première position neutre (celle illustrée notamment sur la figure 4a), une seconde position de correction du quantième (figure 6) et une troisième position de correction du jour de la semaine (figure 7).  This fast correction mechanism comprises a correction flip-flop 80 pivotally mounted on a frame element of the watch movement, between at least one first neutral position (that illustrated in particular in FIG. 4a), a second date correction position ( Figure 6) and a third correction position of the day of the week (Figure 7).
[0091 ] Le mécanisme de correction rapide comporte également un mobile de commande 81 agencé pour définir la position de la bascule à un instant donné, en relation avec l'action d'un ressort 82 agissant sur la bascule 80. The rapid correction mechanism also comprises a control mobile 81 arranged to define the position of the latch at a given instant, in relation with the action of a spring 82 acting on the latch 80.
[0092] Le mobile de commande 81 comporte des première et seconde roues dentées, solidaires en rotation et dont seulement une est visible sur les figures, à savoir la première roue d'entraînement 84. La seconde roue, de commande, présente une denture similaire à celle de la première roue à la différence près que son pas est le triple de celui de la première roue, c'est- à-dire qu'elle ne comporte qu'une dent sur trois. On notera que de manière avantageuse, les deux roues peuvent être formées d'une seule pièce, c'est-à-dire sous la forme d'une seule roue dont deux dents sur trois sont tronquées dans la direction de l'épaisseur de la roue. The control wheel 81 comprises first and second toothed wheels, integral in rotation and only one of which is visible in the figures, namely the first drive wheel 84. The second wheel, control, has a similar toothing to that of the first wheel with the difference that its pitch is three times that of the first wheel, that is to say that it has only one tooth out of three. Note that advantageously, the two wheels can be formed in one piece, that is to say in the form of a single wheel whose two teeth in three are truncated in the direction of the thickness of the wheel.
[0093] La première roue 84 est agencée pour être entraînée en rotation à partir de mouvements de rotation appliqués à une tige de mise à l'heure, de manière conventionnelle. La liaison cinématique entre la tige de mise à l'heure et la roue d'entraînement 84 est conventionnelle, du type comportant notamment un pignon coulant, et ne sera pas décrite plus en détail dans la mesure où l'homme du métier ne rencontrera pas de difficulté particulière pour la mettre en œuvre en fonction de ses besoins.  The first wheel 84 is arranged to be rotated from rotational movements applied to a time setting rod in a conventional manner. The kinematic connection between the time-setting rod and the drive wheel 84 is conventional, of the type comprising in particular a sliding pinion, and will not be described in more detail to the extent that the person skilled in the art will not encounter of particular difficulty to implement it according to its needs.
[0094] La roue de commande est agencée pour coopérer avec un premier bec 86 de la bascule 80 dans le but d'en commander le pivotement. Cette dernière comporte par ailleurs des second et troisième becs 88, 89 agencés pour transmettre des impulsions, respectivement, aux compteurs de quantième et des jours de la semaine. [0095] Lorsque la tige de mise à l'heure est tournée dans un premier sens de rotation prédéfini entraînant une rotation du mobile de commande 81 dans le sens de rotation anti-horaire, la roue de commande agit sur le premier bec de la bascule de manière à faire pivoter cette dernière dans le sens de rotation anti-horaire. Le second bec de la bascule transmet alors une impulsion à la roue de commande 14 du compteur de quantième 13 pour incrémenter ce dernier. Une telle situation est illustrée sur la figure 6. The control wheel is arranged to cooperate with a first nozzle 86 of the latch 80 for the purpose of controlling the pivoting. The latter also comprises second and third nozzles 88, 89 arranged to transmit pulses, respectively, to the date counters and days of the week. When the time setting rod is rotated in a predefined first direction of rotation causing a rotation of the control wheel 81 in the anti-clockwise direction of rotation, the control wheel acts on the first tip of the rocker so as to rotate the latter in the anti-clockwise direction of rotation. The second flip of the flip-flop then transmits a pulse to the control wheel 14 of the date counter 13 to increment the latter. Such a situation is illustrated in Figure 6.
[0096] Lorsque la roue de commande effectue un pas en rotation, sa dent qui a permis le pivotement de la bascule passe au-delà du premier bec de cette dernière et le libère. Du fait que les deux dents suivantes de la roue de commande sont tronquées, le premier bec dispose alors d'un espace suffisant pour permettre un retour immédiat de la bascule dans sa position de repos, sous l'effet de l'action du ressort 82.  When the control wheel takes a step in rotation, the tooth that allowed the pivoting of the rocker passes beyond the first tip of the latter and releases it. Because the two following teeth of the control wheel are truncated, the first nose then has sufficient space to allow an immediate return of the latch in its rest position, under the effect of the action of the spring 82 .
[0097] Si la tige de mise à l'heure est encore pivotée dans le même sens, le compteur de quantième subit d'autres incrémentations successives, à raison d'une incrémentation tous les trois pas en rotation de la roue de commande.  If the time setting rod is again rotated in the same direction, the date counter undergoes further incrementations, one incrementation every three steps in rotation of the control wheel.
[0098] Lorsque la tige de mise à l'heure est tournée dans l'autre sens de rotation entraînant une rotation du mobile de commande 81 dans le sens de rotation horaire, la roue de commande agit sur le premier bec de la bascule de manière à faire pivoter cette dernière dans le sens de rotation horaire. Le troisième bec de la bascule transmet alors une impulsion au pignon 9 du compteur des jours de la semaine 8 pour incrémenter ce dernier. Une telle situation est illustrée sur la figure 7.  When the time setting rod is turned in the other direction of rotation causing a rotation of the control wheel 81 in the clockwise direction, the control wheel acts on the first mouth of the rocker so that to rotate the latter in the direction of clockwise rotation. The third spout of the latch then transmits a pulse to the pinion 9 of the counter days of the week 8 to increment the latter. Such a situation is illustrated in Figure 7.
[0099] Lorsque la roue de commande effectue un pas en rotation, sa dent qui a permis le pivotement de la bascule passe au-delà du premier bec de cette dernière et le libère. Du fait que les deux dents suivantes de la roue de commande sont tronquées, le premier bec dispose alors d'un espace suffisant pour permettre un retour immédiat de la bascule dans sa position de repos, sous l'effet de l'action du ressort 82.  When the control wheel takes a step in rotation, the tooth that allowed the pivoting of the rocker passes beyond the first tip of the latter and releases it. Because the two following teeth of the control wheel are truncated, the first nose then has sufficient space to allow an immediate return of the latch in its rest position, under the effect of the action of the spring 82 .
[00100] Si la tige de mise à l'heure est encore pivotée dans le même sens, le compteur des jours de la semaine subit d'autres incrémentations successives, à raison d'une incrémentation tous les trois pas en rotation de la roue de commande. If the time setting rod is still rotated in the same direction, the counter of the days of the week undergoes further increments successive increments every three steps in rotation of the control wheel.
[00101 ] On notera ainsi que le mécanisme d'entraînement selon la présente invention offre la possibilité d'ajuster le quantième à n'importe quelle heure sans risque de causer des dommages au mécanisme d'entraînement selon l'invention, contrairement à beaucoup de pièces d'horlogerie connues dans lesquelles un réglage du quantième entre 21 h et 3h du matin est à éviter car il peut créer des dommages au mouvement horloger.  [00101] It will be noted that the drive mechanism according to the present invention offers the possibility of adjusting the date at any time without risk of causing damage to the drive mechanism according to the invention, unlike many of timepieces known in which a date adjustment between 21 pm and 3 am is to be avoided because it can create damage to the watch movement.
[00102] La figure 8 représente une vue en perspective éclatée d'un mobile 102, équivalent au mobile 2 illustré sur la figure 2, selon un second mode de réalisation de la présente invention.  [00102] Figure 8 shows an exploded perspective view of a mobile 102, equivalent to the mobile 2 illustrated in Figure 2, according to a second embodiment of the present invention.
[00103] Le principe général de fonctionnement du mobile 102 est similaire à celui du mobile 2. En effet, le mobile 102 comprend une première roue dentée 104 solidaire d'un canon 127 sur lequel sont engagés une came 128 et un organe élastique 129 similaires à ceux du premier mode de réalisation. The general principle of operation of the mobile 102 is similar to that of the mobile 2. In fact, the mobile 102 comprises a first gear 104 secured to a barrel 127 on which are engaged a cam 128 and a resilient member 129 similar to those of the first embodiment.
L'axe central creux du canon est destiné à être engagé sur un tenon porté par un élément de bâti du mouvement horloger pour y monter le mobile à pivot. The hollow central axis of the barrel is intended to be engaged on a tenon carried by a frame member of the watch movement to mount the pivotal mobile.
[00104] Le canon 127 présente un méplat 132 avec lequel coopère une ouverture 133, de forme complémentaire, ménagée dans la base 145 de l'organe élastique 129, ainsi qu'un épaulement 136 définissant une surface de guidage radial pour la came 128, montée sur le canon en étant libre de tourner par rapport à ce dernier.  The barrel 127 has a flat portion 132 with which cooperates an opening 133, of complementary shape, formed in the base 145 of the elastic member 129, and a shoulder 136 defining a radial guide surface for the cam 128, mounted on the barrel being free to turn relative to the latter.
[00105] Le canon 127 porte également un organe de sécurité 138 dont le fonctionnement est similaire à celui de l'organe de sécurité 38 décrit en relation avec le premier mode de réalisation. The barrel 127 also carries a safety member 138 whose operation is similar to that of the safety member 38 described in connection with the first embodiment.
[00106] En effet, l'organe de sécurité 138 comporte une planche dont la périphérie présente un rayon variable. Plus précisément ici, l'organe de sécurité 138 comprend une première portion 201 présentant un premier rayon constant et s'étendant sur un peu plus d'un demi-tour, ainsi qu'une seconde portionIndeed, the safety member 138 comprises a board whose periphery has a variable radius. More specifically here, the safety member 138 comprises a first portion 201 having a first constant radius and extending over a little more than half a turn, and a second portion
202 présentant un second rayon constant et s'étendant sur un peu moins d'un quart de tour. Tandis que la première portion 201 est destinée à être positionnée en regard d'une portion de la came 128 de faible rayon, son premier rayon est en tout point inférieur (ou égal) à celui de la came. La seconde portion 202 est quant à elle destinée à être positionnée en regard de la portion de la came 128 présentant le rayon le plus important et son second rayon est sensiblement supérieur à celui de la came dans cette région. Une pente inclinée 139 par rapport à la direction radiale définit la jonction entre les points de rayon le plus faible et le plus grand. L'organe de sécurité comprend par ailleurs une fente 140 s'étendant sensiblement suivant une trajectoire circulaire et destinée à recevoir une goupille 144 de la came 128. 202 having a second constant radius and extending over a little less than a quarter turn. While the first portion 201 is intended to be positioned opposite a portion of the cam 128 of small radius, its first ray is in all points inferior (or equal) to that of the cam. The second portion 202 is intended to be positioned facing the portion of the cam 128 having the largest radius and its second radius is substantially greater than that of the cam in this region. An inclined slope 139 relative to the radial direction defines the junction between the points of the smallest radius and the largest. The safety member further comprises a slot 140 extending substantially in a circular path and intended to receive a pin 144 of the cam 128.
[00107] L'organe élastique 129 comprend un bras élastique 147 portant deux doigts en formes de griffes 148, 149 orientées en regard l'une de l'autre, à son extrémité libre destinée à coopérer avec la goupille 144. Lorsque le mobile 102 est assemblé et ne subit pas de contrainte externe, la goupille 144 est libre de se positionner entre les deux griffes 148 et 149. The elastic member 129 comprises an elastic arm 147 carrying two fingers in the form of claws 148, 149 facing each other at its free end intended to cooperate with the pin 144. When the mobile 102 is assembled and does not undergo external stress, the pin 144 is free to position between the two claws 148 and 149.
[00108] Les figures 9a et 9b représentent des vues en perspective des première et seconde faces d'un levier 106 destiné à coopérer avec le mobile 102 qui vient d'être décrit. [00108] Figures 9a and 9b show perspective views of the first and second faces of a lever 106 for cooperating with the mobile 102 which has just been described.
[00109] Le levier 106 comporte un alésage 160 destiné à permettre sa fixation à pivot sur un élément de bâti du mouvement horloger et depuis lequel s'étendent des premier et second bras 107 et 1 12, ainsi qu'un ressort 122.  The lever 106 comprises a bore 160 intended to allow its attachment to pivot on a frame member of the watch movement and from which extend first and second arms 107 and 1 12, and a spring 122.
[001 10] Le premier bras 107 comprend, à proximité de son extrémité libre, un bec 161 , assemblé au bras de manière à présenter un léger jeu en pivotement, ainsi qu'un premier doigt rétractable 163, monté pivotant sur le premier bras 107 et agencé pour transmettre des impulsions au pignon 9 du compteur des jours de la semaine 8.  The first arm 107 comprises, near its free end, a spout 161, assembled to the arm so as to have a slight play in pivoting, and a first retractable finger 163 pivotally mounted on the first arm 107 and arranged to transmit pulses to pinion 9 of the day of week counter 8.
[001 1 1 ] Le premier bras 107 présente également un palpeur 168 destiné à coopérer avec la périphérie de l'organe de sécurité 138.  [001 1 1] The first arm 107 also has a feeler 168 intended to cooperate with the periphery of the safety member 138.
[001 12] Par ailleurs, le levier 106 porte une bascule 170, montée en rotation sur le levier, avec un axe de rotation coaxial à l'alésage 160 et, présentant des premier et second bras 171 , 172 respectivement superposés aux premier et second bras du levier 107, 1 12.  [001 12] Furthermore, the lever 106 carries a rocker 170, rotatably mounted on the lever, with an axis of rotation coaxial with the bore 160 and, having first and second arms 171, 172 respectively superimposed on the first and second lever arm 107, 1 12.
[001 13] L'extrémité libre du premier bras 17 1 d e l a b as c u l e, conformée sensiblement en forme de rotule coopère avec le premier doigt rétractable 163. L'extrémité libre du second bras 172 de la bascule, également conformée sensiblement en forme de rotule, coopère avec un second doigt rétractable 174, situé sur l'extrémité libre du second bras 172, pour le faire pivoter sensiblement simultanément au premier doigt rétractable 163. [001 13] The free end of the first arm 17 1 delab as cule shaped substantially substantially ball joint cooperates with the first retractable finger 163. The free end of the second arm 172 of the rocker, also substantially shaped in the form of a ball joint, cooperates with a second retractable finger 174, located on the free end of the second arm 172, to rotate substantially simultaneously to the first finger retractable 163.
[001 14] On notera que la bascule 170 et le bec 161 présentent des surfaces antagonistes de formes sensiblement complémentaires, de telle manière que le premier bec assure un guidage de la bascule et limite l'amplitude de ses déplacements.  [001 14] It will be noted that the rocker 170 and the spout 161 have antagonist surfaces of substantially complementary shapes, such that the first nozzle provides a guide of the rocker and limits the amplitude of its movements.
[001 15] Un ressort 165, formé ici d'une pièce avec le levier 106, est prévu pour appliquer une force sur le second doigt rétractable 174 pour en définir une position de repos. Dans le même temps, le ressort 165 définit la position de repos du premier doigt 163 par l'intermédiaire du second doigt 174 et de la bascule 170. On notera que, de manière avantageuse, une patte 204 est ménagée sur la bascule 170 pour définir un guidage du ressort 165. [001] A spring 165, formed here in one piece with the lever 106, is provided to apply a force on the second retractable finger 174 to define a rest position. At the same time, the spring 165 defines the rest position of the first finger 163 via the second finger 174 and the rocker 170. It will be noted that, advantageously, a tab 204 is provided on the rocker 170 to define a guide of the spring 165.
[001 16] Par ailleurs, il ressort de la figure 9b que le second doigt 1 74 est muni d'une extension 206 présentant une première portion 208 coudée suivie d'un troisième doigt 210 définissant un organe de guidage, comme cela sera exposé plus loin en relation avec les figures suivantes. La première portion 208 présente une épaisseur réduite en référence au second doigt [001 16] Moreover, it appears from Figure 9b that the second finger 1 74 is provided with an extension 206 having a first portion 208 bent followed by a third finger 210 defining a guide member, as will be exposed more far in relation to the following figures. The first portion 208 has a reduced thickness with reference to the second finger
174, tandis que le troisième doigt 210 présente une épaisseur plus importante que celle du second doigt. 174, while the third finger 210 has a greater thickness than that of the second finger.
[001 17] Les figures 10a à 10i représentent la cinématique de fonctionnement du mécanisme d'entraînement instantané selon le second mode de réalisation de la présente invention, dans un premier sens de rotation, dans une même vue de face simplifiée, similaire à celle des figures 4a à 4d. Plus précisément, le premier sens de rotation est ici le sens de fonctionnement normal du mécanisme, c'est-à-dire notamment lorsqu'il est entraîné par le rouage de finissage. Dans un tel mode de fonctionnement, la roue des heures 1 tourne dans le sens de rotation horaire sur les figures[001 17] FIGS. 10a to 10i show the operating kinematics of the instantaneous driving mechanism according to the second embodiment of the present invention, in a first direction of rotation, in the same simplified front view, similar to that of the Figures 4a to 4d. More specifically, the first direction of rotation is here the normal operating direction of the mechanism, that is to say, especially when it is driven by the gear train. In such a mode of operation, the hour wheel 1 rotates in the clockwise direction in the figures
10a à 10i, ce qui correspond à une rotation du mobile 102 dans le sens de rotation anti-horaire. [001 18] Partant du rayon le plus faible de la périphérie de la came 128, associé à une heure située immédiatement après minuit d'un jour donné (figure 10a), le bec 161 suit, pendant près de 24 heures, la périphérie de la came 128 jusqu'à la position illustrée sur la figure 10d, qui correspond à une heure proche de minuit du jour suivant. En effet, la roue 104 étant entraînée dans le sens de rotation anti-horaire, elle entraîne la came 128 dans le même sens par coopération de sa fente 140 avec la goupille 144 portée par la came 128. 10a to 10i, which corresponds to a rotation of the mobile 102 in the anti-clockwise direction of rotation. [001 18] Starting from the smallest radius of the periphery of the cam 128, associated with a time immediately after midnight of a given day (FIG. 10a), the spout 161 follows, for nearly 24 hours, the periphery of the cam 128 to the position shown in Figure 10d, which corresponds to a time close to midnight of the following day. Indeed, the wheel 104 being driven in the direction of rotation anti-clockwise, it drives the cam 128 in the same direction by cooperation of its slot 140 with the pin 144 carried by the cam 128.
[001 19] Le rayon de la périphérie de la came 128 situé en regard du bec 161 augmentant progressivement, le levier 106 pivote lentement dans le sens horaire, dans le même temps, de telle manière que son premier bras 107 s'éloigne progressivement du centre de la came 128.  [001 19] The radius of the periphery of the cam 128 located facing the spout 161 increasing gradually, the lever 106 pivots slowly in the clockwise direction, at the same time, so that its first arm 107 moves progressively away from the center of the cam 128.
[00120] Il ressort des figures 10a à 10i qu'une goupille fixe 212 est agencée sur le bâti du mouvement horloger, de manière à coopérer avec l'extension 206 solidaire du second doigt 174.  It is apparent from Figures 10a to 10i that a fixed pin 212 is arranged on the frame of the watch movement, so as to cooperate with the extension 206 secured to the second finger 174.
[00121 ] Plus précisément, pendant les heures qui précèdent minuit, le troisième doigt 210 repose sur la goupille 212 par une première face incurvée 214.  More specifically, during the hours preceding midnight, the third finger 210 rests on the pin 212 by a first curved surface 214.
[00122] Au fur et à mesure que le levier 106 pivote dans le sens de rotation horaire, en passant de la configuration de la figure 10a à celle de la figure 10d, le troisième doigt 210 est retenu par la goupille 212, ce qui force la planche portant le second doigt 174 à pivoter progressivement dans le sens de rotation anti-horaire pour contourner la goupille par le haut sur la représentation des figures.  As the lever 106 pivots in the clockwise direction, from the configuration of Figure 10a to that of Figure 10d, the third finger 210 is retained by the pin 212, which forces the board carrying the second finger 174 to pivot gradually in the anti-clockwise direction to circumvent the pin from above on the representation of the figures.
[00123] Ce mouvement de rotation du second doigt 174 entraîne une rotation de la bascule 170 dans le sens horaire en référence au levier 106, entraînant de ce fait un pivotement du premier doigt 163 dans le sens de rotation antihoraire. Ainsi, plus le levier tourne et plus les premier et second doigts 163 et 174 sont rétractés et peuvent passer en regard des dentures avec lesquelles ils sont destinés à coopérer sans être à leur portée.  This rotational movement of the second finger 174 causes a rotation of the latch 170 in the clockwise direction with reference to the lever 106, thereby causing a pivoting of the first finger 163 in the counterclockwise direction of rotation. Thus, the more the lever rotates and the first and second fingers 163 and 174 are retracted and can pass next to the teeth with which they are intended to cooperate without being within their reach.
[00124] Juste avant le changement de quantième et de jour, le troisième doigt 210 franchit la goupille, tel que cela apparaît sur la figure 10d et peut reprendre sa position de repos sous l'effet de l'action du ressort 165. Les premier et second doigts 163 et 174 pivotent alors en sens inverse pour se rapprocher des dentures avec lesquelles ils sont destinés à coopérer. Just before the change of date and day, the third finger 210 passes the pin, as it appears in Figure 10d and can resume its rest position under the effect of the action of the spring 165. The first and second fingers 163 and 174 then pivot in the opposite direction to approach the teeth with which they are intended to cooperate.
[00125] Sur les figures 10e et 1 0f, la came 128 poursuit sa rotation et entraîne toujours le levier 106, aussi le troisième doigt 210 se trouve à nouveau en butée contre la goupille 212, cette fois par une seconde face 216 opposée à la première face 214. La planche portant l'extension 206 et le second doigt 174 pivote alors dans le sens de rotation horaire, entraînant le premier doigt 163 dans le même sens, par l'intermédiaire de la bascule 170. In FIGS. 10e and 10f, the cam 128 continues its rotation and always drives the lever 106, so the third finger 210 is again in abutment against the pin 212, this time by a second face 216 opposite to the first face 214. The board carrying the extension 206 and the second finger 174 then pivots in the direction of clockwise rotation, driving the first finger 163 in the same direction, via the lever 170.
[00126] Sur la figure 10f, alors que le bec 161 quitte le point de la périphérie de la came 128 de plus grand rayon pour faire chuter le levier 106, suivant le sens de rotation anti-horaire, on constate que les premier et second doigts 163 et 174 sont agencés à portée des dentures avec lesquelles ils coopèrent. In Figure 10f, while the spout 161 leaves the point of the periphery of the cam 128 of greater radius to drop the lever 106, in the direction of rotation anti-clockwise, we see that the first and second fingers 163 and 174 are arranged close to the teeth with which they cooperate.
[00127] Pendant la chute du levier 106, tel que cela ressort de la figure 10g, la face 216 du troisième doigt 210 glisse le long de la goupille 212 jusqu'à ce que cette dernière se trouve en regard de la première portion 208 coudée de l'extension 206. During the fall of the lever 106, as shown in Figure 10g, the face 216 of the third finger 210 slides along the pin 212 until the latter is facing the first portion 208 cranked of the extension 206.
[00128] L'épaisseur de la première portion 208 est choisie de telle manière que la goupille 212 peut traverser l'extension 206 en passant à son niveau, tel que représenté sur la figure 10h, tandis que le levier 106 poursuit sa chute.  The thickness of the first portion 208 is chosen such that the pin 212 can cross the extension 206 by passing at its level, as shown in Figure 10h, while the lever 106 continues its fall.
[00129] A cet instant, chacun des doigts 163 et 174 transmet une impulsion à la roue qu'il commande, sous l'effet de l'action de la chute du levier 106, tel que représenté sur la figure 10i.  At this moment, each of the fingers 163 and 174 transmits a pulse to the wheel that it controls, under the effect of the action of the fall of the lever 106, as shown in Figure 10i.
[00130] Le mécanisme se replace alors dans la position illustrée sur la figure 10a.  The mechanism then returns to the position shown in Figure 10a.
[00131 ] Lorsqu'un utilisateur effectue une correction de l'heure en arrière, le mécanisme selon le présent mode de réalisation réagit de manière similaire à ce qui a été décrit en relation avec le premier mode de réalisation.  When a user makes a correction of the time back, the mechanism according to the present embodiment reacts similarly to what has been described in connection with the first embodiment.
[00132] L'organe de sécurité 138 agit sur le levier 106, par l'intermédiaire du palpeur 168, pour le faire pivoter dans le sens de rotation horaire. [00133] Au cours de la montée du levier 106, le troisième doigt 210 reproduit le chemin prédéfini par sa coopération avec la goupille 212, tel qu'il vient d'être décrit en relation avec les figures 10a à 10d. The safety member 138 acts on the lever 106, via the feeler 168, to rotate in the clockwise direction of rotation. During the rise of the lever 106, the third finger 210 reproduces the predefined path by its cooperation with the pin 212, as just described in connection with Figures 10a to 10d.
[00134] A ce stade, que la roue 104 soit entraînée dans un sens ou dans l'autre, le troisième doigt 210 se comporte comme décrit plus haut en relation avec les figures 10e à 10i et chacun des premier et second doigts 163, 174 transmet une impulsion à la roue correspondante.  At this stage, whether the wheel 104 is driven in one direction or the other, the third finger 210 behaves as described above in relation to FIGS. 10e to 10i and each of the first and second fingers 163, 174 transmits a pulse to the corresponding wheel.
[00135] Il ressort de la description qui précède du mécanisme selon le second mode de réalisation que celui-ci offre une sécurité supplémentaire, en référence au premier mode de réalisation, permettant d'éviter des sauts multiples des roues 9 et 14 lors du fonctionnement normal du mécanisme, voire même des sauts intempestifs en cas de chocs par exemple.  It follows from the foregoing description of the mechanism according to the second embodiment that it provides additional security, with reference to the first embodiment, to avoid multiple jumps wheels 9 and 14 during operation. normal mechanism, or even accidental jumps in case of shocks for example.
[00136] La figure 1 1 représente une vue de face d'un détail de construction selon une variante de réalisation de la présente invention, plus précisément d'un levier 306, similaire au levier 106 de la figure 9a mais, dont l'extrémité du premier bras 307, qui interagit avec le pignon 9 à sept dents, présente une extension 308 supplémentaire destinée à augmenter le niveau de sécurité du dispositif, en relation avec le risque de sauts doubles de l'organe d'affichage des jours de la semaine.  FIG. 11 represents a front view of a construction detail according to an alternative embodiment of the present invention, more specifically of a lever 306, similar to the lever 106 of FIG. 9a, but whose end of the first arm 307, which interacts with the seven toothed pinion 9, has an additional extension 308 intended to increase the level of security of the device, in connection with the risk of double jumps of the display member days of the week .
[00137] En effet, l'extension 308 présente sensiblement la forme d'un bec agencé à portée de la denture du pignon 9, de telle manière qu'une paroi 310 du bec définit une butée pour cette denture dans le sens de rotation horaire. Ainsi, lorsque le levier 306 pivote, de la manière exposée en relation avec le levier 106 et les illustrations des figures 10h et 10i, pour incrémenter l'affichage des jours de la semaine, l'extension 308 se positionne entre deux dents du pignon 9 pour supprimer tout risque de saut double. Indeed, the extension 308 has substantially the shape of a spout arranged within the range of the toothing of the pinion 9, such that a wall 310 of the spout defines a stop for this toothing in the direction of clockwise rotation. . Thus, when the lever 306 pivots, in the manner disclosed in relation to the lever 106 and the illustrations of Figures 10h and 10i, to increment the display days of the week, the extension 308 is positioned between two teeth of the pinion 9 to eliminate any risk of double jump.
[00138] On notera que l'inclinaison de la paroi 310 en référence aux dents du pignon 9 permet avantageusement à ces dernières d'exercer une force sur l'extension 308 pour soulever le levier 306 lors d'opérations de correction d u jour de la semaine faisant intervenir la bascule de correction 80, comme illustré sur la figure 7.  It will be noted that the inclination of the wall 310 with reference to the teeth of the pinion 9 advantageously allows the latter to exert a force on the extension 308 to lift the lever 306 during correction operations of the day of the week involving the correction flip-flop 80, as shown in Figure 7.
[00139] La description qui précède s'attache à décrire un mode de réalisation particulier à titre d'illustration non limitative et, l'invention n'est pas limitée à la mise en œuvre de certaines caractéristiques particulières qui viennent d'être décrites, comme par exemple la nature des informations affichées ou encore le fait que le levier 6, 106 comprend deux bras pour actionner simultanément deux compteurs. De même, les formes représentées pour les différents constituants du mécanisme d'entraînement selon la présente invention ne sont pas limitatives. The foregoing description attempts to describe a particular embodiment by way of non-limiting illustration and the invention is not limited. to the implementation of certain particular characteristics that have just been described, such as the nature of the information displayed or the fact that the lever 6, 106 comprises two arms for simultaneously operating two counters. Similarly, the shapes shown for the various components of the drive mechanism according to the present invention are not limiting.
[00140] L'homme du métier ne rencontrera pas de difficulté particulière pour adapter le contenu de la présente divulgation à ses propres besoins et mettre en œuvre un mécanisme d'entraînement instantané comportant un mobile agencé pour tourner dans un sens prédéfini, en mode de fonctionnement normal, et pour commander les déplacements d'un levier dans le but de transmettre des impulsions instantanées à au moins un compteur d'un mouvement horloger, le mécanisme comportant en outre un organe de sécurité coaxial au mobile et agencé pour permettre une rotation du mobile dans le sens contraire sans risque de dommage, sans sortir du cadre de la présente invention.  The skilled person will not encounter any particular difficulty to adapt the content of the present disclosure to his own needs and implement an instant drive mechanism comprising a mobile arranged to rotate in a predefined direction, in operating mode. normal operation, and to control the movements of a lever for the purpose of transmitting instantaneous pulses to at least one counter of a watch movement, the mechanism further comprising a security member coaxial with the mobile and arranged to allow a rotation of the mobile in the opposite direction without risk of damage, without departing from the scope of the present invention.
[00141] A titre d'exemple, en ce qui concerne le second mode de réalisation, il est possible d'inverser les positions du troisième doigt 210 et de la goupille fixe 212 sans sortir du cadre de l'invention, c'est-à-dire de prévoir que la came définie par le troisième doigt est fixée sur le bâti du mouvement horloger tandis que la goupille est portée par l'extension 206 du second doigt 174. En outre, l'invention n'est pas non plus limitée à la mise en œuvre d'un seul ensemble troisième doigt - goupille. En effet, il est possible de prévoir un ensemble similaire pour commander les impulsions transmises au compteur des jours de la semaine, par exemple ou de toute autre information affichée dans le cadre d'autres applications. La bascule 170 n'est plus nécessaire dans ce cas. Il est alors possible de régler indépendamment l'une de l'autre les pénétrations des premier et second doigts 163, 174 dans les dentures qui leur sont associées.  By way of example, as regards the second embodiment, it is possible to invert the positions of the third finger 210 and the fixed pin 212 without departing from the scope of the invention, that is, that is to say that the cam defined by the third finger is fixed on the watch movement of the frame while the pin is carried by the extension 206 of the second finger 174. In addition, the invention is also not limited to the implementation of a single set third finger - pin. Indeed, it is possible to provide a similar set to control the pulses transmitted to the counter days of the week, for example or any other information displayed in the context of other applications. The flip-flop 170 is no longer necessary in this case. It is then possible to adjust independently of one another the penetrations of the first and second fingers 163, 174 in the teeth associated with them.
[00142] Par ailleurs, on notera que, de manière avantageuse, la périphérie de la came présente une courbe étudiée en fonction de la force du ressort 22, 122 telle qu'elle tourne à couple sensiblement constant.  Furthermore, it will be noted that, advantageously, the periphery of the cam has a curve studied as a function of the force of the spring 22, 122 as it rotates at substantially constant torque.
