[0001 ] La présente invention concerne un mécanisme d'actionnement pour mouvement horloger comportant The present invention relates to an actuating mechanism for a watch movement comprising
un premier mobile destiné à être entraîné par un mobile entraîneur du mouvement horloger,  a first mobile intended to be driven by a mobile trainer of the watch movement,

le premier mobile comportant des première et seconde dentures, solidaires en rotation et, définissant respectivement des premier et second niveaux suscepti bles de coopérer respectivement avec le m obile entraîneur et le second mobile.  the first movable having first and second sets of teeth rotatably secured and respectively defining first and second levels capable of cooperating respectively with the driving arm and the second movable respectively.
[0002] Selon un mode de réalisation préféré, le premier mobile présente la forme d'une roue munie de la denture à sa périphérie. According to a preferred embodiment, the first mobile has the shape of a wheel provided with the toothing at its periphery.
[0003] L'invention concerne également un mouvement horloger muni d'un tel mécanisme ainsi qu'une pièce d'horlogerie comportant un tel mouvement horloger. The invention also relates to a watch movement provided with such a mechanism and a timepiece comprising such a watch movement.
Etat de la technique State of the art
[0004] Des mécanismes de ce type ont déjà été divulgués, notamment en relation avec l'indication du quantième perpétuel.  Mechanisms of this type have already been disclosed, in particular in connection with the indication of the perpetual calendar.
[0005] A titre d'exemple, la demande de brevet EP 1351 104A1 et le brevet CH 680630A3, auquel la demande européenne se réfère, présentent un mobile dont toutes les dents sauf une sont tronquées suivant la direction radiale. Toutes les dents coopèrent avec un premier mobile, entraîneur, tandis que seule la dent pleine coopère avec un second mobile, entraîné. By way of example, the patent application EP 1351 104A1 and the patent CH 680630A3, to which the European application refers, have a mobile, all but one of the teeth are truncated in the radial direction. All the teeth cooperate with a first mobile, coach, while only the full tooth cooperates with a second mobile, driven.
[0006] Ce type de mobile est relativement fréquent dans les mécanismes d'affichage du quantième mais se rencontre peu dans d'autres applications. Divulgation de l'invention This type of mobile is relatively common in the display mechanisms of the date but meets little in other applications. Disclosure of the invention
[0007] Un but principal de la présente invention est de proposer une alternative aux applications mettant en œuvre des mobiles à plusieurs niveaux de dentures connues de l'art antérieur, en proposant un mécanisme co m p re n a nt u n te l m o b i l e et présentant une cinématique de fonctionnement différente, visant notamment à actionner un mécanisme supplémentaire du mouvement horloger correspondant.  [0007] A main object of the present invention is to propose an alternative to applications using mobile devices with several teeth levels known from the prior art, by proposing a mechanism that is compatible with a mobile phone and having kinematics. of different operation, aimed in particular to actuate an additional mechanism of the corresponding watch movement.
[0008] A cet effet, la présente invention concerne plus particulièrement un mécanisme d'actionnement du type mentionné plus haut, caractérisé par le fait qu'il comporte en outre un organe élastique agencé pour agir sur le second mobile et définir une position de repos de ce dernier, dans laquelle il est situé à portée de la seconde denture mais hors de portée de la première denture. Ce mécanisme est également caractérisé par le fait que la seconde denture présente un pas prédéfini tel que le second mobile est susceptible d'être pivoté en réponse à un déplacement du premier mobile avant de reprendre sa position de repos entre deux dents de la seconde denture.  For this purpose, the present invention relates more particularly to an actuating mechanism of the type mentioned above, characterized in that it further comprises an elastic member arranged to act on the second mobile and define a rest position of the latter, in which it is located within range of the second toothing but out of reach of the first toothing. This mechanism is also characterized in that the second toothing has a predefined pitch such that the second mobile is pivotable in response to a displacement of the first mobile before returning to its rest position between two teeth of the second toothing.
[0009] De manière préférée, les première et seconde dentures du mobile sont agencées suivant la direction de l'épaisseur du premier mobile définissant des premier et second étages de dentures.  Preferably, the first and second teeth of the mobile are arranged in the direction of the thickness of the first mobile defining first and second stages of teeth.
[0010] Grâce à ces caractéristiques, le premier mobile peut être agencé dans un mouvement horloger pour être entraîné par un mobile entraîneur, coopérant avec un premier étage de denture, pour commander les déplacements du second mobile par l'intermédiaire du second étage de denture, le second mobile présentant un mouvement alternatif entre au moins une position pivotée et une position de repos.  With these features, the first mobile can be arranged in a watch movement to be driven by a driving mobile, cooperating with a first gear stage, to control the movement of the second mobile via the second gear stage , the second mobile having an alternating movement between at least one pivoted position and a rest position.
[001 1] En particulier, on peut prévoir que le second mobile peut être une bascule comportant avantageusement un bec agencé pour coopérer avec la seconde denture du premier mobile.  [001 1] In particular, it can be provided that the second mobile can be a rocker advantageously comprising a nozzle arranged to cooperate with the second toothing of the first mobile.
[0012] Par ailleurs, l'organe élastique peut comporter une surface de butée agencée pour coopérer avec une surface d'appui adaptée ménagée sur la bascule pour en définir la position de repos. [0013] Selon un mode de réalisation préféré, la bascule est susceptible de pivoter suivant des premier et second sens de rotation respectifs selon que le premier mobile est entraîné, respectivement, dans un premier et dans un second sens de rotation. Furthermore, the elastic member may comprise an abutment surface arranged to cooperate with a suitable bearing surface provided on the rocker to define the rest position. According to a preferred embodiment, the rocker is pivotable in respective first and second directions of rotation as the first mobile is driven, respectively, in a first and a second direction of rotation.
[0014] Grâce à ces caractéristiques, la bascule peut soit actionner un mécanisme supplémentaire du mouvement horloger correspondant, dans des premier et second sens opposés, soit actionner deux mécanismes supplémentaires distincts, en fonction du sens dans lequel elle est elle- même entraînée par le premier mobile.  With these characteristics, the rocker can either actuate an additional mechanism of the corresponding watch movement, in first and second opposite directions, or actuate two separate additional mechanisms, depending on the direction in which it is itself driven by the first mobile.
[0015] A cet effet, la bascule comprend avantageusement un second bec susceptible d'agir sur un premier mobile entraîné du mouvement horloger lorsque la bascule pivote suivant le premier sens de rotation et, un troisième bec susceptible d'agir sur un second mobile entraîné du mouvement horloger lorsque la bascule pivote suivant le second sens de rotation.  For this purpose, the latch advantageously comprises a second nose capable of acting on a first driven mobile watch movement when the rocker pivots in the first direction of rotation and a third nozzle capable of acting on a second mobile driven the watch movement when the rocker pivots in the second direction of rotation.
[0016] En particulier, on peut prévoir que le mécanisme d'actionnement selon l'invention est un mécanisme de correction d'une ou deux indications d'un mouvement horloger, comme par exemple le quantième et le jour de la semaine. Dans ce cas, un premier sens de pivotement de la bascule est associé à la correction du quantième, tandis que le second sens de pivotement de la bascule est associé à la correction du jour de la semaine.  In particular, it can be provided that the actuating mechanism according to the invention is a correction mechanism of one or two indications of a watch movement, such as the date and the day of the week. In this case, a first pivoting direction of the rocker is associated with the correction of the date, while the second direction of pivoting of the rocker is associated with the correction of the day of the week.
[0017] Par ailleurs, la présente invention concerne également un mouvement horloger muni d'un mécanisme d'actionnement du type qui vient d'être décrit, associé à un premier mécanisme supplémentaire agencé pour commander les déplacements du premier mobile et, au moins un second mécanisme supplémentaire agencé pour être actionné à partir des mouvements de la bascule.  Furthermore, the present invention also relates to a watch movement provided with an actuating mechanism of the type just described, associated with a first additional mechanism arranged to control the movements of the first mobile and, at least one second additional mechanism arranged to be operated from the movements of the rocker.
[0018] Le premier mobile peut être réalisé comme deux organes dentés rapportés et solidaires suivant la direction générale des déplacements du mobile. De manière avantageuse, le premier mobile peut être réalisé sous la forme d'un organe denté dont certaines dents sont tronquées.  The first mobile can be realized as two toothed members reported and secured in the general direction of movement of the mobile. Advantageously, the first mobile can be made in the form of a toothed body of which some teeth are truncated.
[0019] Suivant un mode de réalisation préféré, le premier mobile est une roue dentée dont certaines dents sont tronquées suivant la direction de l'épaisseur du mobile de manière à définir deux dentures réparties sur deux étages. According to a preferred embodiment, the first mobile is a toothed wheel whose teeth are truncated in the direction of the thickness of the mobile so as to define two sets of teeth distributed over two floors.

[0026] Plus précisément, la figure 1 représente un premier mobile 1 , selon un mode de réalisation préféré de la présente invention, destiné à être entraîné par un mobile entraîneur 2 pour actionner un second mobile 3.More specifically, FIG. 1 represents a first mobile 1, according to a preferred embodiment of the present invention, intended to be driven by a driving mobile 2 to actuate a second mobile 3.

[0027] Le premier mobile 1 présente ici la forme d'une roue, ou d'une couronne, présentant une denture à sa périphérie comprenant 30 dents ici, de manière illustrative non limitative. [0028] Il apparaît de la figure 1 que certaines dents 6 de la denture sont tronquées dans le sens de l'épaisseur du premier mobile 1. Plus précisément, deux dents sur trois sont tronquées, sensiblement à mi- hauteur, de telle manière qu'une dent 8 sur trois est pleine.

It appears from Figure 1 that some teeth 6 of the toothing are truncated in the direction of the thickness of the first mobile 1. More specifically, two teeth out of three are truncated, substantially at half height, so that one tooth out of three is full.
[0029] Ainsi, la denture présente une première denture, ou un premier étage, 10 comportant à la fois les dents tronquées 6 et les dents pleines 8 et une seconde denture, ou un second étage, 12 comprenant une alternance entre dents pleines 8 et des vides dus au fait que deux dents sur trois sont tronquées. Dans le cas de figure illustré ici, à titre illustratif, le pas du second étage est le triple de celui du premier étage.  Thus, the toothing has a first toothing, or a first stage, comprising both the truncated teeth 6 and the solid teeth 8 and a second toothing, or a second stage, 12 comprising an alternation between solid teeth 8 and voids due to the fact that two teeth out of three are truncated. In the case illustrated here, for illustrative purposes, the pitch of the second floor is triple that of the first floor.
[0030] Bien entendu, il est possible de prévoir, en alternative, que le premier mobile 1 est formé de deux planches superposées et solidaires en rotation, dont chacune porterait l'une des dentures 10, 12, sans sortir du cadre de la présente invention.  Of course, it is possible to provide, alternatively, that the first mobile 1 is formed of two superimposed and rotationally fixed boards, each of which would carry one of the teeth 10, 12, without departing from the scope of this invention.
[0031] Le premier étage 10 de la denture est destiné à coopérer avec le mobile entraîneur pour assurer l'entraînement en rotation du premier mobile 1.  The first stage 10 of the toothing is intended to cooperate with the driving mobile to ensure the rotational drive of the first mobile 1.
[0032] Le second étage 12 de la denture est agencé pour coopérer avec le second mobile 3, présentant ici la forme d'une bascule apte à être montée rotative sur le bâti du mouvement horloger, au moyen d'un trou 14 destiné à recevoir une vis (non représentée). Le trou 14 définit l'axe de rotation de la bascule 3 en référence au bâti.  The second stage 12 of the toothing is arranged to cooperate with the second mobile 3, here having the shape of a rocker adapted to be rotatably mounted on the frame of the watch movement, by means of a hole 14 for receiving a screw (not shown). The hole 14 defines the axis of rotation of the rocker 3 with reference to the frame.
[0033] La bascule 3 présente deux bras principaux 16, 18, s'étendant de part et d'autre du trou 14 suivant des directions générales sensiblement alignées.  The latch 3 has two main arms 16, 18, extending on either side of the hole 14 in substantially aligned general directions.
[0034] Le premier bras 16 s'étend initialement suivant une direction légèrement incurvée avant de se séparer en deux branches 20, 22, portant respectivement des premier et second becs 24, 26 à leur extrémité libre.  The first arm 16 initially extends in a slightly curved direction before separating into two branches 20, 22, respectively carrying first and second spouts 24, 26 at their free end.
[0035] Le second bras 18 présente un décrochement 28, en forme générale de C et, destiné à éviter une collision de la bascule avec un autre mobile du mouvement horloger, tel que cela ressortira des figures 2 et 3, avant de se terminer par un troisième bec 30, dont la fonction sera exposée plus loin en relation avec ces mêmes figures.  The second arm 18 has a recess 28 in the general shape of C and intended to avoid a collision of the latch with another mobile watch movement, as will be apparent from Figures 2 and 3, before ending with a third nozzle 30, whose function will be explained later in relation to these same figures.
[0036] Le premier bec 24 est destiné à coopérer avec la denture du premier mobile 1 , tel que cela ressort de la figure 1 , tandis que le second bec 26 est destiné à coopérer avec un mobile entraîné (non visible sur la figure 1). The first nozzle 24 is intended to cooperate with the toothing of the first mobile 1, as shown in Figure 1, while the second nozzle 26 is intended to cooperate with a driven mobile (not visible in Figure 1).
[0037] Plus particulièrement, le premier bec 24 est disposé dans le plan général du second étage 12 de la denture de manière à coopérer uniquement avec les dents pleines 8, la première denture 10 étant située dans un autre plan, soit hors de portée du premier bec 24.  More particularly, the first nozzle 24 is disposed in the general plane of the second stage 12 of the toothing so as to cooperate only with the solid teeth 8, the first toothing 10 being located in another plane, or out of range of the first beak 24.
[0038] Par ailleurs, la bascule 3 présente deux niveaux d'épaisseur suivant la direction de sa longueur pour définir une surface d'appui 31 , adjacente au trou 14 et, destinée à coopérer avec une surface de butée 32 d'un organe élastique 34 monté fixe sur un élément de bâti du mouvement horloger. Les surfaces d'appui 31 et de butée 32 sont ici sensiblement planes.  Furthermore, the rocker 3 has two thickness levels along the direction of its length to define a bearing surface 31, adjacent to the hole 14 and intended to cooperate with an abutment surface 32 of an elastic member 34 mounted fixed on a frame member of the watch movement. The bearing surfaces 31 and abutment 32 are here substantially planar.
[0039] L'organe élastique 34 est agencé pour exercer sur la bascule 3 une force tendant à la positionner dans une position de repos illustrée sur la figure 1 , dans laquelle le premier bec 24 est disposé à portée de la seconde denture 12 du premier mobile.  The elastic member 34 is arranged to exert on the rocker 3 a force tending to position it in a rest position shown in Figure 1, wherein the first nozzle 24 is disposed within range of the second toothing 12 of the first mobile.
[0040] Il ressort de la figure 1 que si le premier mobile 1 est entraîné en rotation dans le sens horaire, la dent pleine 8 située immédiatement à côté du premier bec 24 va entrer en contact avec ce dernier et exercer sur lui une force tendant à s'opposer à la force de l'organe élastique 34 et à faire pivoter la bascule 3 dans le sens horaire.  It is apparent from Figure 1 that if the first mobile 1 is rotated in the clockwise direction, the full tooth 8 located immediately next to the first nozzle 24 will come into contact with the latter and exert on it a force tending to oppose the force of the elastic member 34 and to pivot the rocker 3 in the clockwise direction.
[0041] A l'inverse, si le premier mobile 1 est entraîné en rotation dans le sens anti-horaire, la première dent pleine 8 située à gauche du premier bec 24 sur la figure 1 va entrer en contact avec ce dernier et exercer sur lui une force tendant à s'opposer à la force de l'organe élastique 34 et à faire pivoter la bascule 3 dans le sens anti-horaire.  Conversely, if the first mobile 1 is rotated in the counterclockwise direction, the first full tooth 8 located to the left of the first nose 24 in Figure 1 will come into contact with the latter and exercise on it a force tending to oppose the force of the elastic member 34 and to pivot the rocker 3 in the counterclockwise direction.
[0042] On comprend de ce qui précède que, selon que la bascule pivote dans un sens ou dans l'autre, les second et troisième becs sont susceptibles d'agir sur des mécanismes supplémentaires du mouvement horloger correspondant, comme cela va ressortir de la description qui suit, faite en relation avec un mode de réalisation préféré illustré sur les figures 2 à 4.  It is understood from the above that, depending on whether the rocker pivots in one direction or the other, the second and third nozzles are likely to act on additional mechanisms of the corresponding watch movement, as will emerge from the description which follows, made in connection with a preferred embodiment illustrated in Figures 2 to 4.
[0043] Les figures 2 à 4 représentent, à titre non limitatif, une application préférée du mécanisme d'actionnement qui vient d'être décrit en relation avec la figure 1 , dans trois configurations différentes de ce mécanisme permettant d'en saisir le mode de fonctionnement. Figures 2 to 4 show, without limitation, a preferred application of the actuating mechanism which has just been described in connection with the Figure 1, in three different configurations of this mechanism to enter the mode of operation.
[0044] Plus précisément, les figures 2 à 4 illustrent, de manière simplifiée, une partie d'un mouvement horloger destiné à permettre l'affichage du jour de la semaine et du quantième sous la forme de grande date. More specifically, Figures 2 to 4 illustrate, in a simplified manner, a part of a watch movement intended to allow the display of the day of the week and the date in the form of large date.
[0045] A cet effet, le mouvement horloger comporte des mobiles ou étoiles des jours 40, des unités de quantième 41 et des dizaines de quantième 42, destinées à être solidaires, respectivement, de disques indicateurs des jours, des unités de quantième et des dizaines de quantième (non représentés). Le positionnement angulaire de chacune des étoiles est assuré par un sautoir 44, de manière connue.  For this purpose, the watch movement comprises mobiles or stars of the days 40, date units 41 and date dozens 42, intended to be secured, respectively, of the day indicator discs, date units and dozens of days (not shown). The angular positioning of each of the stars is provided by a jumper 44, in a known manner.
[0046] Pour assurer l'entraînement des étoiles 40 à 42, le mouvement horloger comporte une chaussée 46 et une roue des heures 48, reliées cinématiquement par un mobile de minuterie 50. Ce dernier entraîne un mobile de commande 52, par l'intermédiaire d'un mobile de réduction 54, dimensionné pour que le mobile de commande fasse un tour sur lui-même en vingt quatre heures, de manière connue. To ensure the training of stars 40 to 42, the watch movement comprises a roadway 46 and a hour wheel 48, kinematically connected by a timer mobile 50. The latter drives a control mobile 52, via a reduction mobile 54, dimensioned so that the control mobile makes a turn on itself in twenty four hours, in a known manner.
[0047] Le mobile de commande 52 comprend une came 56 en colimaçon agencée pour coopérer avec un bec 58 d'une bascule de commande 60 montée pivotante sur un élément de bâti du mouvement horloger (en principe une platine, non représentée). The control mobile 52 comprises a cam 56 in spiral arranged to cooperate with a spout 58 of a control lever 60 pivotally mounted on a frame member of the watch movement (in principle a plate, not shown).
[0048] La bascule de commande 60 comporte deux doigts 61 , 62 agencés pour agir respectivement sur l'étoile des jours 40 et une roue programmée 64.The control rocker 60 comprises two fingers 61, 62 arranged to act respectively on the star of days 40 and a programmed wheel 64.
Plus précisément, lorsque le mobile de commande 52 tourne sur lui- même, dans le sens de rotation anti-horaire sur la figure 2 et à partir de sa position illustrée, la came 56 soulève progressivement le bec 58 jusqu'à ce qu'une portion de forte pente de la périphérie de la came 56, définissant la jonction entre sa portion de plus grand rayon et sa portion de rayon le plus faible, arrive en regard du bec 58. A cet instant, le bec 58 tombe sur la portion de la came 56 présentant le rayon le plus faible, entraînant un pivotement brutal de la bascule de commande 60 dans le sens de rotation anti-horaire. [0049] Ce mouvement de la bascule de commande 60 induit des actions respectives du doigt 61 sur l'étoile des jours 40 et du doigt 62 sur la roue programmée 64 pour les faire avancer d'un pas chacune, dans le sens de rotation horaire. More specifically, when the control wheel 52 rotates on itself, in the counterclockwise direction of rotation in FIG. 2 and from its illustrated position, the cam 56 progressively raises the nose 58 until a steep portion of the periphery of the cam 56, defining the junction between its largest radius portion and its weakest radius portion, arrives opposite the nozzle 58. At this time, the nozzle 58 falls on the portion of the cam 56 having the smallest radius, causing a sudden pivoting of the control rocker 60 in the anti-clockwise direction of rotation. This movement of the control rocker 60 induces respective actions of the finger 61 on the star of the days 40 and the finger 62 on the programmed wheel 64 to advance one step each, in the direction of clockwise rotation. .
[0050] La stabilité de la position angulaire de la roue programmée 64 est également assurée par un sautoir 66 supplémentaire. The stability of the angular position of the programmed wheel 64 is also provided by an additional jumper 66.
[0051 ] De manière connue, la roue programmée 64 comporte deux dentures 68, de trente-et-une dents, et 69, de quatre dents, agencées pour agir respectivement sur les étoile des unités de quantième 41 et des dizaines de quantième 42.  In known manner, the programmed wheel 64 comprises two teeth 68, of thirty-one teeth, and 69, of four teeth, arranged to act respectively on the star of date units 41 and dozens of date 42.
[0052] Ainsi, lors du fonctionnement normal du mouvement horloger, l'étoile des jours 40 et la roue programmée 64 sont entraînées d'un pas par jour pour modifier le jour et le quantième affichés.  Thus, during normal operation of the watch movement, the day star 40 and the programmed wheel 64 are driven one step per day to change the day and the date displayed.
[0053] Le mécanisme d'actionnement décrit en relation avec la figure 1 est intégré au mouvement horloger représenté sur les figures 2 à 4 pour remplir la fonction d'un mécanisme de correction de l'indication du jour de la semaine et du quantième.  The actuating mechanism described in connection with Figure 1 is integrated with the watch movement shown in Figures 2 to 4 to fulfill the function of a correction mechanism of the indication of the day of the week and the date.
[0054] On notera que le mécanisme d'actionnement est visible, sur les figures 2 à 4, par son côté opposé à celui qui était apparent sur la figure 1 .  Note that the actuating mechanism is visible in Figures 2 to 4, by its opposite side to that which was apparent in Figure 1.
[0055] Le premier mobile 1 et la bascule 3 sont disposés dans la région centrale du mouvement horloger de telle manière que le second bec 26 de la bascule 3 soit situé à portée de la denture de l'étoile des jours 40 et, que le troisième bec 30 soit situé à portée de la dentu re 68 de la roue programmée 64. The first mobile 1 and the latch 3 are arranged in the central region of the watch movement so that the second spout 26 of the latch 3 is located within the range of the teeth of the star of the days 40 and that the third spout 30 is located within reach of the teeth 68 of the programmed wheel 64.
[0056] Partant de la configuration de la figure 1 , les figures 2 et 3 illustrent la cinématique de fonctionnement du mécanisme d'actionnement selon la présente invention lorsqu'il est mis en œuvre pour effectuer la correction du quantième. Starting from the configuration of FIG. 1, FIGS. 2 and 3 illustrate the operating kinematics of the actuating mechanism according to the present invention when it is implemented to effect the correction of the date.
[0057] Dans ce but, le premier mobile 1 est entraîné dans le sens de rotation anti- horaire et entraîne la bascule 3 dans le même sens.  For this purpose, the first mobile 1 is driven in the anticlockwise direction and causes the latch 3 in the same direction.
[0058] Le troisième bec 30 entre alors en contact avec la denture 68 de la roue programmé pour induire une rotation de cette dernière dans le sens de rotation horaire, soit pour incrémenter la valeur du quantième affiché. [0059] Dans la configuration illustrée sur la figure 2, le saut du quantième est en cours, le troisième bec 30 étant en appui contre une dent de la denture 68 pour s'opposer à la force exercée par le sautoir 66. The third spout 30 then comes into contact with the toothing 68 of the programmed wheel to induce a rotation of the latter in the clockwise direction of rotation, or to increment the displayed date value. In the configuration illustrated in FIG. 2, the jump of the date is in progress, the third spout 30 bearing against a tooth of the toothing 68 to oppose the force exerted by the jumper 66.
[0060] On notera que le décrochement 28 de la bascule 3 permet d'éviter une collision de cette dernière avec le mobile de minuterie, lors de la correction du quantième. Note that the recess 28 of the flip-flop 3 avoids a collision of the latter with the mobile timer, during the correction of the date.
[0061] La figure 3 illustre la configuration en fin de saut, lorsque le sautoir 66 a repris une position stable entre deux dents de la denture 68, tandis que la dent 8 agissant sur le premier bec 24 est sur le point de libérer ce dernier pour permettre à la bascule 3 de reprendre sa position de repos, sous l'effet de l'action de l'organe élastique 34. Le retour de la bascule à sa position de repos (telle qu'illustrée sur la figure 1) est possible du fait que la seconde denture 12 du premier mobile présente un pas suffisamment grand, ici le triple de celui de la première denture 10 à titre illustratif non limitatif, pour que le premier bec 24 de la bascule puisse se loger entre deux dents 8 consécutives.  Figure 3 illustrates the configuration at the end of the jump, when the jumper 66 has resumed a stable position between two teeth of the toothing 68, while the tooth 8 acting on the first spout 24 is about to release the latter to allow the rocker 3 to resume its rest position, under the effect of the action of the elastic member 34. The return of the rocker to its rest position (as shown in Figure 1) is possible because the second toothing 12 of the first mobile has a sufficiently large pitch, here three times that of the first toothing 10 for illustrative non-limiting, so that the first spout 24 of the rocker can be housed between two consecutive teeth 8.
[0062] Partant de la configuration de la figure 1 , la figure 4 illustre la cinématique de fonctionnement du mécanisme d'actionnement selon la présente invention lorsqu'il est mis en œuvre pour effectuer la correction du jour de la semaine.  Starting from the configuration of FIG. 1, FIG. 4 illustrates the operating kinematics of the actuating mechanism according to the present invention when it is implemented to effect the correction of the day of the week.
[0063] Dans ce but, le premier mobile 1 est entraîné dans le sens de rotation horaire et entraîne la bascule 3 dans le même sens, par pression d'une dent 8 sur le premier bec 24.  For this purpose, the first mobile 1 is driven in the clockwise direction and drives the lever 3 in the same direction, by pressing a tooth 8 on the first nozzle 24.
[0064] Il apparaît de la figure 4 que le second bec 26 de la bascule est alors déplacé pour agir sur une dent de l'étoile des jours 40 et faire tourner cette dernière dans le sens de rotation horaire, pour incrémenter l'indication du jour de la semaine d'un jour.  It appears from Figure 4 that the second spout 26 of the rocker is then moved to act on a tooth of the star of days 40 and rotate the latter in the clockwise direction, to increment the indication of the day of the week a day.
[0065] De manière similaire à ce qui a été décrit plus haut, lorsque la dent 8 passe au-delà du premier bec 24, la bascule 3 reprend sa position de repos, entre deux dents 8, sous l'effet de l'action de l'organe élastique 34.  Similarly to what has been described above, when the tooth 8 passes beyond the first nozzle 24, the rocker 3 resumes its rest position, between two teeth 8, under the effect of the action. of the elastic member 34.
[0066] Il est évident que, dans un sens de rotation ou l'autre, lorsque le premier mobile est entraîné de manière prolongée, la bascule 3 présente un mouvement oscillant entre sa position de repos et l'une des positions de correction, pour incrémenter soit le quantième soit le jour de la semaine de plusieurs pas. It is obvious that, in one direction of rotation or the other, when the first mobile is driven in a prolonged manner, the rocker 3 has an oscillating movement between its rest position and one of the positions of correction, to increment either the date or the day of the week by several steps.
[0067] L'homme du métier ne rencontrera pas de difficulté particulière pour mettre en œuvre un mécanisme supplémentaire destiné à assurer l'entraînement en rotation du premier mobile 1 . Selon un mode de réalisation préféré, la pièce d'horlogerie correspondante comporte un organe de commande externe, avantageusement une couronne rotative de remontage et/ou de mise à l'heure susceptible d'occuper une pluralité de positions axiales, de manière connue. Ainsi, l'une de ces positions axiales peut être prévue de sorte à établir une liaison cinématique, notamment au moyen d'un pignon coulant, entre une tige solidaire en rotation de la couronne de remontage et le premier mobile 1 . De ce fait, chaque sens de rotation de la couronne est associé à un sens de rotation particulier du premier mobile 1 , dans le but de corriger soit le quantième soit le jour de la semaine.  The skilled person will not encounter any particular difficulty to implement an additional mechanism for ensuring the rotational drive of the first mobile 1. According to a preferred embodiment, the corresponding timepiece comprises an external control member, advantageously a rotating winding and / or time-setting ring capable of occupying a plurality of axial positions, in a known manner. Thus, one of these axial positions may be provided so as to establish a kinematic connection, in particular by means of a sliding pinion, between a rod integral in rotation with the winding crown and the first mobile 1. Therefore, each direction of rotation of the ring is associated with a particular direction of rotation of the first mobile 1, in order to correct either the date or the day of the week.
[0068] On notera que l'homme du métier pourra également adapter le rapport de démultiplication de cette liaison cinématique en fonction de ses propres besoins, de même que le pas de la seconde denture 12 du premier mobile 1 . Le nombre de dents tronquées 6 prévu entre deux dents pleines 8 consécutives doit être suffisant pour permettre à la bascule 3 de reprendre sa position de repos entre deux actionnements successifs. Outre la forme et les dimensions du premier bec 24, ce nombre dépend notamment du diamètre du premier mobile 1 . On notera toutefois que dans le cas illustré, à titre d'exemple non limitatif, ce nombre de dents tronquées 6 situées entre deux dents pleines 8 successives pourrait être égal ou supérieur à un, de manière générale, sans sortir du cadre de la présente invention. De manière alternative ou complémentaire, le nombre de dents pleines peut être égale ou supérieur à un. Dans le cas d'un nombre plus faible de dents pleines, il est simplement nécessaire de tourner davantage la couronne de remontage pour effectuer des incréments de correction.  Note that the skilled person can also adapt the gear ratio of this kinematic link according to its own needs, as well as the pitch of the second toothing 12 of the first mobile 1. The number of truncated teeth 6 provided between two consecutive solid teeth 8 must be sufficient to allow the latch 3 to resume its rest position between two successive actuations. In addition to the shape and dimensions of the first nozzle 24, this number depends in particular on the diameter of the first mobile 1. Note however that in the illustrated case, by way of non-limiting example, this number of truncated teeth 6 located between two successive solid teeth 8 could be equal to or greater than one, in general, without departing from the scope of the present invention. . Alternatively or additionally, the number of full teeth may be equal to or greater than one. In the case of a smaller number of full teeth, it is simply necessary to further turn the winding crown to perform correction increments.
[0069] 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 le nombre ou la nature des informations affichées. De même, les formes représentées pour les différents constituants du mécanisme d'actionnement selon la présente invention ne sont pas limitatives, notamment celle de la bascule 3. The foregoing description seeks 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 come to be described, such as the number or nature of information displayed. Similarly, the shapes shown for the various constituents of the actuating mechanism according to the present invention are not limiting, in particular that of the lever 3.
[0070] 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'actionnement comportant un premier mobile comprenant deux dentures, l'une pour permettre son entraînement et l'autre pour entraîner un second mobile agencé pour pivoter, sous l'effet de l'action d'un organe élastique, entre une position de repos et au moins une position d'actionnement, dans laquelle il est susceptible d'agir sur un mécanisme supplémentaire, 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 actuating mechanism comprising a first mobile comprising two sets of teeth, one to allow training and the other for driving a second mobile arranged to pivot, under the effect of the action of an elastic member, between a rest position and at least one actuating position, in which it is likely to act on an additional mechanism, without departing from the scope of the present invention.
[0071 ] A titre d'exemple illustratif non limitatif, on rappellera q ue les deux dentures du premier mobile peuvent être alternativement réalisées par l'assemblage de deux roues superposées rendues solidaires en rotation l'une de l'autre. En outre, il est également possible que les deux niveaux définis par ces dentures soient des niveaux pris suivant la direction radiale des dentures, autrement dit que les dents de l'une des deux dentures soient plus longues que celles de l'autre. Par exemple, on peut prévoir que le premier mobile comporte une seule denture dont certaines dents sont tronquées. Ces deux dentures peuvent ainsi être indifféremment situées dans des plans différents ou dans un même plan pour mettre en œuvre le mécanisme selon la présente invention. By way of nonlimiting illustrative example, it will be recalled that the two teeth of the first mobile can be alternately made by the assembly of two superimposed wheels made integral in rotation with one another. In addition, it is also possible that the two levels defined by these teeth are levels taken in the radial direction of the teeth, that is to say that the teeth of one of the two teeth are longer than those of the other. For example, it can be provided that the first mobile has a single toothing, some teeth are truncated. These two teeth can thus be indifferently located in different planes or in the same plane to implement the mechanism according to the present invention.
[0072] Tel que cela a été mentionné plus haut, il est également possible de prévoir que la bascule 3 n'est agencée pour actionner qu'un seul mécanisme supplémentaire, soit dans un seul sens avec un seul bec, soit dans deux sens opposés, la bascule présentant dans ce cas deux becs agencés pour agir dans deux sens opposés sur le même mécanisme. As mentioned above, it is also possible to provide that the flip-flop 3 is arranged to actuate only one additional mechanism, either in one direction with a single spout, or in two opposite directions. , the rocker having in this case two beaks arranged to act in two opposite directions on the same mechanism.
[0073] Par ailleurs, on notera que la présente invention n'est pas limitée à un premier mobile présentant la forme d'une roue. En effet, il est possible de mettre en œuvre les caractéristiques qui viennent d'être décrites sur une crémaillère ou sur un râteau sans sortir du cadre de l'invention, par exemple. De manière similaire, les mobiles entraînés 40 et 64 pourraient aussi présenter des déplacements linéaires sans sortir du cadre de la présente invention. Furthermore, it should be noted that the present invention is not limited to a first mobile having the shape of a wheel. Indeed, it is possible to implement the features that have just been described on a rack or on a rake without departing from the scope of the invention, for example. Similarly, the driven mobiles 40 and 64 could also present linear displacements without departing from the scope of the present invention.
