Description

La présente invention se rapporte aux mécanismes de quantième pour pièces d'horlogerie. Elle concerne plus particulièrement les quantièmes de type annuel ou perpétuel. On appelle quantième perpétuel ou annuel un mécanisme corrigeant automatiquement la date lorsque le mois a moins de trente et un jours, selon qu'il effectue ou non la correction correcte au mois de février durant les années bissextiles.The present invention relates to calendar mechanisms for timepieces. It relates more particularly to the annual or perpetual calendar. A perpetual or annual calendar is called a mechanism that automatically corrects the date when the month is less than thirty-one days, depending on whether or not it performs the correct correction in February during leap years.

On connaît de nombreux mécanismes de ce type. Pour la plupart d'entre eux, les sauts de l'indicateur de quantième sont assurés par des cames et des leviers. De telles solutions sont peu sûres et gourmandes en énergie.Many mechanisms of this type are known. For most of them, the jumps of the date indicator are provided by cams and levers. Such solutions are unsafe and energy hungry.

Dans le document CH 680'630, l'entraînement se fait sans qu'interviennent des leviers ou autres ressorts. Dans ce cas, toutefois, la source d'énergie de la pièce d'horlogerie est fortement sollicitée à la fin des mois de moins de trente et un jours, et tout particulièrement en février, puisque le dispositif d'affichage doit effectuer jusqu'à quatre pas le même jour. Le but de la présente invention est de réduire la consommation ponctuelle d'énergie, en la répartissant au cours du mois.In the document CH 680'630, the drive is done without the intervention of levers or other springs. In this case, however, the energy source of the timepiece is strongly solicited at the end of the months of less than thirty-one days, and particularly in February, since the display device must perform up to four steps on the same day. The object of the present invention is to reduce the point consumption of energy, by distributing it during the month.

De manière plus précise, la pièce d'horlogerie est munie d'un mécanisme de quantième, comportant :

  • un rouage de minuterie,
  • un dispositif d'affichage muni d'un mobile dont la position est fonction du quantième du mois,
  • un organe de correction coopérant avec ledit dispositif d'affichage et assurant son entraînement à la fin des mois de moins de trente et un jours.
More precisely, the timepiece is provided with a date mechanism, comprising:
  • a clockwork,
  • a display device provided with a mobile whose position is a function of the calendar of the month,
  • a correction member cooperating with said display device and ensuring its training at the end of the months of less than thirty-one days.

Selon l'invention, le mécanisme de quantième que comporte cette pièce d'horlogerie comprend, en outre :

  • un organe des mois ayant une période de une année et comportant une came avançant par pas, à raison de un pas par mois,
  • un organe de programmation, entraîné par le rouage de minuterie et coopérant avec l'organe des mois, et muni d'un mobile coopérant avec l'organe de correction pour le faire avancer, en cours de mois, d'autant de pas que le mois compte de jour en moins de trente et un.
According to the invention, the date mechanism of this timepiece comprises, in addition:
  • an organ of the months having a period of one year and comprising a cam advancing in steps, at the rate of one step per month,
  • a programming device, driven by the timer train and cooperating with the body months, and provided with a mobile cooperating with the correction device to advance it, during the month, as many steps as the month count of day in less than thirty-one.

Dans ce mécanisme, l'organe de correction comporte un dispositif d'actionnement relié au dispositif d'affichage pour lui permettre d'avancer, en fin de mois, du nombre de pas dont l'organe de correction a été avancé durant le mois qui se termine. De la sorte, ce mécanisme permet de corriger automatiquement le quantième durant les mois de moins de trente et un jours, sans toutefois nécessairement pouvoir prendre en compte les années bissextiles.In this mechanism, the correction element comprises an actuating device connected to the display device to enable it to advance, at the end of the month, the number of steps the correction device has been advanced during the month that end. In this way, this mechanism makes it possible to automatically correct the date during the months of less than thirty-one days, without necessarily being able to take into account the leap years.

De manière avantageuse, le mécanisme comprend, en outre, un organe des années bissextiles coopérant avec l'organe de programmation durant les mois de février, de manière telle que, même durant les années bissextiles, la date est automatiquement corrigée, également en février.Advantageously, the mechanism further comprises a leap year organ cooperating with the programming organ during the months of February, so that even during leap years, the date is automatically corrected, also in February.

Afin d'assurer la mise en phase de l'organe de correction, celui-ci comporte un mobile et un organe élastique reliant ce mobile au dispositif d'affichage.To ensure the phasing of the correction member, it comprises a mobile and a resilient member connecting the mobile to the display device.

L'organe de programmation comprend avantageusement :

  • une première roue reliée cinématiquement au dispositif d'affichage,
  • une roue satellite portée par la première roue,
  • des deuxième et troisième roues solidaires en rotation et engrenant respectivement avec ladite roue satellite et le mobile de l'organe de correction, et
  • au moins un organe de retenue commandé par l'organe de programmation, agencé de manière à pouvoir être engagé ou non sur le chemin parcouru par la roue satellite, pour décaler ainsi les première et troisième roues et, avec elles, le mobile de programmation et le dispositif d'affichage.
The programming unit advantageously comprises:
  • a first wheel kinematically connected to the display device,
  • a satellite wheel carried by the first wheel,
  • second and third wheels integral in rotation and meshing respectively with said satellite wheel and the mobile of the correction element, and
  • at least one retaining member controlled by the programming member, arranged so as to be able to be engaged or not on the path traveled by the satellite wheel, to thereby shift the first and third wheels and, with them, the programming mobile and the display device.

L'organe de retenue est avantageusement formé de couronnes disposées concentriquement aux première, deuxième et troisième roues de l'organe de programmation, et de sautoirs commandés au moins par l'organe des mois.The retaining member is advantageously formed of rings arranged concentrically at the first, second and third wheels of the programming member, and jumpers controlled at least by the month member.

Afin d'assurer une correction correcte du quantième même durant les mois de février des années bissextiles, les sautoirs sont commandés d'une part par l'organe des mois, d'autre part par l'organe des années bissextiles.In order to ensure a correct correction of the date even during the months of February leap years, the jumpers are ordered on the one hand by the organ of the months, on the other hand by the organ of leap years.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée à titre d'exemple et faite en référence au dessin dans lequel:

  • Les figures 1 et 2 représentent une vue d'ensemble, respectivement en perspective et de dessus, d'un mécanisme selon l'invention ; et
  • Les figures 3 et 4 sont des vues respectivement en perspective et de dessus d'une partie de ce mécanisme.
The invention will be better understood on reading the description which follows, given by way of example and with reference to the drawing in which:
  • Figures 1 and 2 show an overview, respectively in perspective and from above, of a mechanism according to the invention; and
  • Figures 3 and 4 are views respectively in perspective and from above of a part of this mechanism.

Le mécanisme représenté aux figures 1 et 2 est commandé par un rouage de minuterie de pièce d'horlogerie qui n'est pas représenté au dessin. Ce rouage entraîne une roue vingt-quatre heures 10, qui effectue un tour par jour. La roue 10 porte des index 12, 13 et 14, l'index 13 étant masqué sur la figure 1. Une roue en étoile 16, destinée à porter un indicateur des jours de la semaine, est actionnée par l'index 12. Les index 13 et 14 sont destinés à mouvoir le mécanisme de quantième perpétuel, comme cela sera expliqué ci-dessous. Ce dernier comprend essentiellement quatre modules.The mechanism shown in FIGS. 1 and 2 is controlled by a timepiece timer train which is not shown in the drawing. This wheel drives a wheel twenty-four hours 10, which performs one turn per day. The wheel 10 carries indexes 12, 13 and 14, the index 13 being masked in FIG. 1. A star wheel 16, intended to bear an indicator of the days of the week, is actuated by the index 12. The indexes 13 and 14 are intended to move the perpetual calendar mechanism, as will be explained below. The latter essentially comprises four modules.

Un premier module 18, de périodicité mensuelle, comprend deux roues superposées 18a et 18b, comportant chacune trente et une dents, trois d'entre elles étant tronquées dans leur épaisseur, comme on peut le voir plus particulièrement sur la figure 1, et entraînées successivement et respectivement par les index 13 et 14. La roue inférieure 18b occupe une position correspondant au quantième du mois. L'affichage de cette fonction peut se faire soit au moyen d'une aiguille 19 que porte son arbre, soit en entraînant un anneau de quantième, non représenté au dessin.A first module 18, of monthly periodicity, comprises two superimposed wheels 18a and 18b, each having thirty-one teeth, three of them being truncated in their thickness, as can be seen more particularly in FIG. 1, and driven successively. and respectively by the indexes 13 and 14. The lower wheel 18b occupies a position corresponding to the day of the month. The display of this function can be done either by means of a needle 19 that carries his shaft, or by driving a date ring, not shown in the drawing.

La roue supérieure 18a est rigidement associée à un index 18c dont la fonction sera précisée plus loin. Un ressort 18dschématiquement représenté sur la figure 2, relie élastiquement les roues 18a et 18b l'une à l'autre. Ce ressort est destiné à accumuler de l'énergie au cours des mois de moins de trente et un jours, pour assurer des sauts supplémentaires de la roue 18b à la fin du mois, comme cela sera expliqué plus loin.The upper wheel 18a is rigidly associated with an index 18c whose function will be specified later. A spring 18schematically shown in Figure 2, elastically connects the wheels 18a and 18b to each other. This spring is intended to accumulate energy during months of less than thirty-one days, to ensure additional jumps of the wheel 18b at the end of the month, as will be explained below.

Les roues 18a et 18b sont respectivement positionnées par des sautoirs 20 et 22, maintenus en appui dans les dentures de ces roues sous l'effet de ressorts non représentés au dessin. Le sautoir 22 est muni d'un bras 22a dont la fonction sera précisée plus loin.The wheels 18a and 18b are respectively positioned by jumpers 20 and 22, maintained in support in the teeth of these wheels under the effect of springs not shown in the drawing. The jumper 22 is provided with an arm 22a whose function will be specified later.

Un deuxième module 24, de périodicité annuelle, entraîné de un pas chaque mois par l'index 18c, comporte, superposés et rigidement solidaires les uns des autres :

  • une étoile des mois de trente jours 24a, comportant quatre branches disposer de manière à ce qu'elles soient actives en fin de mois d'avril, juin, septembre et novembre,
  • un index de février 24b comportant deux branches,
  • une came des mois de moins de trente et un jours 24c, destinée à coopérer avec le bras 22a du cliquet 22 pour le dégager de la roue 18b,
  • une étoile des mois 24d de douze branches, coopérant avec l'index 18c, et
  • un index 24e dont la fonction sera précisée plus loin.
A second module 24, of annual periodicity, driven by a step each month by the index 18c, comprises, superimposed and rigidly secured to each other:
  • a star of months of thirty days 24a, comprising four branches to be arranged so that they are active at the end of April, June, September and November,
  • a February 24b index with two branches,
  • a cam of months less than thirty-one days 24c, intended to cooperate with the arm 22a of the pawl 22 to disengage it from the wheel 18b,
  • a star of months 24d of twelve branches, cooperating with the index 18c, and
  • a 24th index whose function will be specified later.

Ce deuxième module 24 est positionné par un ressort sautoir non représenté coopérant, de manière classique, avec l'étoile 24d. Il peut avantageusement porter une aiguille 25 affichant le mois.This second module 24 is positioned by a not shown jumper spring cooperating, in a conventional manner, with the star 24d. It can advantageously carry a needle 25 displaying the month.

Un troisième module 26, de périodicité quadriennale, est commandé par l'index 24b. Il a pour fonction d'assurer la gestion des sauts associés aux mois de février, prenant en compte le fait que l'année soit ou non bissextile, comme cela sera expliqué plus loin. Il comprend, solidaires en rotation, une étoile à huit branches 26a destinée à coopérer avec l'index à deux branches 24b, un index bissextile 26b, une étoile tronquée des années non bissextiles 26c, comportant trois branches, deux étant dans le prolongement l'une de l'autre, la troisième étant perpendiculaire, ainsi qu'une étoile 26d à quatre branches. Cette dernière, qui pivote librement sur l'arbre portant les autres composants de ce module 26, tourne sous l'effet de l'index 24e. Elle est positionnée par un sautoir non représenté au dessin. Une aiguille 27, indiquant le cycle des années bissextiles, est portée par l'étoile 26d.A third module 26, of quadrennial periodicity, is controlled by the index 24b. Its function is to manage the jumps associated with the month of February, taking into account the fact that the year is leap year or not, as will be explained later. It includes, solidary in rotation, a star to eight branches 26a intended to cooperate with the index with two branches 24b, a leap-index 26b, a truncated star of non-leap years 26c, having three branches, two being in the extension of one another, the third being perpendicular , as well as a star 26d with four branches. The latter, which pivots freely on the shaft carrying the other components of this module 26, rotates under the effect of the index 24e. It is positioned by a jumper not shown in the drawing. A needle 27, indicating the cycle of leap years, is carried by the star 26d.

Enfin, un quatrième module 28, de correction, représenté plus en détail aux figures 3 et 4, est formé d'un différentiel comportant :

  • une première roue 28a de vingt-huit dents, engrenant avec la roue 18a,
  • une deuxième roue 28b, de même diamètre et ayant le même nombre de dents que la roue 28a, engrenant avec la roue 18b,
  • une troisième roue 28c de vingt huit dents, interposée entre les roues 28a et 28b, de plus petit diamètre et solidaire de la roue 28a,
  • une roue satellite 28d de douze dents, montée mobile en rotation sur la roue 28b et engrenant avec la roue 28c par son pignon 28d', lequel comporte également douze dents.
Finally, a fourth correction module 28, shown in more detail in FIGS. 3 and 4, is formed of a differential comprising:
  • a first wheel 28a of twenty-eight teeth, meshing with the wheel 18a,
  • a second wheel 28b, of the same diameter and having the same number of teeth as the wheel 28a, meshing with the wheel 18b,
  • a third wheel 28c of twenty-eight teeth, interposed between the wheels 28a and 28b, of smaller diameter and integral with the wheel 28a,
  • a satellite wheel 28d of twelve teeth, rotatably mounted on the wheel 28b and meshing with the wheel 28c by its pinion 28d ', which also comprises twelve teeth.

On notera que, sur la figure 3, la roue 28b a été tronquée, pour rendre visible la partie du module qui se trouve en dessous d'elle.Note that in Figure 3, the wheel 28b has been truncated to make visible the portion of the module below it.

La roue 28b porte, en outre, concentriquement, montées mobiles en rotation, trois couronnes 28e, 28f et 28g, munies d'une denture extérieure 28h, 28i et 28j et de respectivement une, deux ou trois dents intérieures 28k, 281 et 28m, destinées à coopérer avec la roue satellite 28d. Les couronnes 28f et 28g sont interposées entre les roues 28a et 28b, alors que la couronne 28e se trouve sur l'autre face de la roue 28b. En outre, la roue satellite 28d présente une première planche, dont l'épaisseur est suffisante pour qu'elle se trouve au niveau des deux dentures intérieures 281 et 28m des couronnes 28f et 28g, et une deuxième planche coopérant avec la denture intérieure de la couronne 28e.The wheel 28b bears, in addition, concentrically rotatably mounted, three rings 28e, 28f and 28g, provided with an external toothing 28h, 28i and 28j and respectively one, two or three inner teeth 28k, 281 and 28m, intended to cooperate with the satellite wheel 28d. The rings 28f and 28g are interposed between the wheels 28a and 28b, while the ring 28e is on the other side of the wheel 28b. In addition, the satellite wheel 28d has a first board, whose thickness is sufficient for it to be at the two inner teeth 281 and 28m of the rings 28f and 28g, and a second board cooperating with the internal toothing of the 28th crown.

Comme on peut le voir sur la figure 3, la couronne 28g est munie d'une gorge 28n et la roue 28a de doigts 28o engagés dans cette gorge, assurant un positionnement relatif de la couronne 28g et de la roue 28a. Les couronnes 28e et 28f sont positionnées de la même manière, en référence à la roue 28b.As can be seen in Figure 3, the ring 28g is provided with a groove 28n and the wheel 28a 28o fingers engaged in this groove, ensuring a relative positioning of the ring 28g and the wheel 28a. The rings 28e and 28f are positioned in the same manner, with reference to the wheel 28b.

Trois sautoirs 30, 32 et 34 sont disposés de manière à pouvoir être engagés respectivement dans les dentures 28h, 28i et 28j des couronnes 28e, 28f et 28g et à coopérer respectivement avec l'étoile des mois de trente jours 24a, l'index bissextile 26b et avec l'étoile tronquée 26c.Three jumpers 30, 32 and 34 are arranged so as to be engaged respectively in the teeth 28h, 28i and 28j of the crowns 28e, 28f and 28g and to cooperate respectively with the star of the thirty-day month 24a, the leap-index 26b and with the truncated star 26c.

On relèvera que les roues 28a et 28b sont disposées de manière à ce que, durant trois jours par mois, leur denture n'engrène pas respectivement avec les roues 18a et 18b, du fait que les dents des roues 18a et 18b sont tronquées dans leur épaisseur.It will be noted that the wheels 28a and 28b are arranged so that, for three days per month, their teeth do not mesh respectively with the wheels 18a and 18b, because the teeth of the wheels 18a and 18b are truncated in their teeth. thickness.

Le dispositif tel qu'il vient d'être décrit est agencé de manière à ce que, durant les mois de moins de trente et un jours, la roue 18a soit déphasée par rapport à la roue 18b de un, deux ou trois pas, en autant de jours, selon que le mois en cours compte trente, vingt-neuf ou vingt-huit jours. Son fonctionnement est le suivant.The device as just described is arranged so that during the months of less than thirty-one days, the wheel 18a is out of phase with the wheel 18b by one, two or three steps, as many days, depending on whether the current month is thirty, twenty-nine or twenty-eight days. Its operation is as follows.

A chaque jour, aux environs de minuit, l'index 12 fait avancer de un pas la roue en étoile 16 de l'indicateur de jours de la semaine. Cet entraînement se fait de manière systématique et indépendamment du reste du dispositif. Cette fonction pourrait même être supprimée sans rien changer au fonctionnement du dispositif.Every day, around midnight, the index 12 advances the star wheel 16 of the weekday indicator by one step. This training is done systematically and independently of the rest of the device. This function could even be deleted without changing the operation of the device.

En outre, les index 13 et 14 font respectivement tourner de un pas les roues 18a et 18b. Celles-ci entraînent respectivement les roues 28a et 28b, sauf durant les trois jours durant lesquels les dents tronquées se trouvent en regard des roues 28a et 28b. L'aiguille 19 saute de un pas avec la roue 18b à laquelle elle est associée. Ce processus se déroule tous les jours.In addition, the indexes 13 and 14 rotate the wheels 18a and 18b respectively. These drive the wheels 28a and 28b, respectively, except during the three days during which the truncated teeth are opposite the wheels 28a and 28b. The needle 19 jumps one step with the wheel 18b with which it is associated. This process takes place every day.

Plus précisément, l'index 13 commence par entraîner la roue 18a dans le sens horaire, laquelle fait tourner la roue 28a et avec elle la roue 28c, dans le sens anti-horaire. Comme la roue 28b est fixe à ce moment-là, le mouvement de la roue 28c fait tourner le pignon 28d' et la roue satellite 28d dans le sens horaire, de un douzième de tour. Ensuite, l'index 14 entraîne la roue 18b et, par cette dernière, la roue 28b, laquelle entraîne la roue satellite 28d dans le sens anti-horaire, qui retrouve sa position antérieure sur la roue 28b. Lorsque la denture de la roue satellite 28d rencontre les dents de l'une des dentures intérieures des couronnes 28e, 28f ou 28g, elle coopère avec elles.More specifically, the index 13 begins by driving the wheel 18a clockwise, which rotates the wheel 28a and with it the wheel 28c, in the counterclockwise direction. Since the wheel 28b is fixed at this time, the movement of the wheel 28c rotates the pinion 28d 'and the satellite wheel 28d clockwise one twelfth of a turn. Then, the index 14 drives the wheel 18b and, by the latter, the wheel 28b, which drives the satellite wheel 28d in the counterclockwise direction, which returns to its previous position on the wheel 28b. When the toothing of the satellite wheel 28d meets the teeth of one of the internal teeth of the rings 28e, 28f or 28g, it cooperates with them.

Si aucune des couronnes n'est retenue par un sautoir, ces dernières tournent, sans autre, avec la roue 28b. De la sorte, durant les mois de trente et un jour, la roue satellite 28d entraîne, avec elle, les trois couronnes 28e, 28f et 28g.If none of the crowns is held by a jumper, the latter turn, without further, with the wheel 28b. In this way, during the thirty-one day period, the satellite wheel 28d carries with it the three crowns 28e, 28f and 28g.

Pendant les mois de moins de trente et un jour, un sautoir retient l'une des couronnes. Ainsi, durant les mois de février des années non bissextiles, le sautoir 34 bloque la couronne 28g, qui comporte trois dents 28m. Comme la roue satellite 28d tourne dans le sens horaire lorsque la roue 28a avance de un pas dans le sens anti-horaire, sa denture se met à cheval sur une dent de la couronne 28g. Lorsque, ensuite, la roue 28b tourne de un pas dans le sens anti-horaire, la roue satellite 28d tourne dans le sens horaire tout en engrenant avec la denture de la couronne 28g, faisant ainsi avancer la roue 28a de un pas supplémentaire. La même situation se retrouve les deux jours suivants. De la sorte, la roue 28a aura avancé de trois pas supplémentaires. Ensuite, la roue satellite 28d n'est plus en prise avec la denture intérieure de la couronne 28g.During the months of less than thirty-one days, a saltire holds one of the crowns. Thus, during February non-leap years, the jumper 34 blocks the 28g crown, which has three teeth 28m. As the satellite wheel 28d rotates clockwise when the wheel 28a advances a step in the counter-clockwise direction, its toothing straddles a tooth of the crown 28g. When, then, the wheel 28b rotates a step in the counterclockwise direction, the satellite wheel 28d rotates clockwise while meshing with the toothing of the ring 28g, thereby advancing the wheel 28a by one additional step. The same situation is found the next two days. In this way, the wheel 28a will have advanced three additional steps. Then, the satellite wheel 28d is no longer in engagement with the internal toothing of the ring 28g.

Pour les mois de vingt neuf et de trente jours, le fonctionnement est le même, la roue satellite 28d coopérant respectivement avec les couronnes 28f et 28e, lesquelles sont respectivement retenues par les sautoirs 32 et 30.For the months of twenty-nine and thirty days, the operation is the same, the satellite wheel 28d cooperating respectively with the rings 28f and 28e, which are respectively retained by the jumpers 32 and 30.

Afin de permettre une meilleure compréhension du fonctionnement du dispositif, celui-ci sera décrit en fonction de ce qui se passe tout au long de l'année.In order to allow a better understanding of the functioning of the device, it will be described according to what happens throughout the year.

Durant le mois de décembre, qui est un mois de trente et un jours, les modules 24 et 26 sont dans des positions telles que les sautoirs 30, 32 et 34 ne sont pas sollicités. De la sorte, tout au long du mois, les roues 18a et 18b tournent régulièrement, entraînant avec elles les roues 28a et 28b et les couronnes 28e, 28f et 28g, aucune de ces dernières n'étant retenue. Par ailleurs, à cause des dents tronquées, les roues 28a et 28b restent immobiles durant trois jours en cours de mois. Ainsi, les pièces constitutives du module 28 font un tour durant le mois.During the month of December, which is a month of thirty-one days, the modules 24 and 26 are in positions such that the jumpers 30, 32 and 34 are not solicited. In this way, throughout the month, the wheels 18a and 18b rotate regularly, driving with them the wheels 28a and 28b and the crowns 28e, 28f and 28g, none of the latter being retained. Moreover, because of the truncated teeth, the wheels 28a and 28b remain motionless for three days during the month. Thus, the component parts of the module 28 make a turn during the month.

Le dernier jour du mois, l'index 18c coopère avec la roue en étoile 24d, de sorte que les composants du module 24 tournent de un pas de 30°, amenant l'aiguille 25 dans la position correspondant au mois de janvier. En outre, l'index 24e entraîne la roue en étoile 26d et, avec elle, l'aiguille 27 indiquant où se situe l'année qui commence dans le cycle des années bissextiles.On the last day of the month, the index 18c cooperates with the star wheel 24d, so that the components of the module 24 rotate by a 30 ° pitch, bringing the needle 25 in the position corresponding to the month of January. In addition, the index 24e drives the starwheel 26d and with it the needle 27 indicating where the year beginning in the leap year cycle is.

Le mois de janvier comporte, lui aussi, trente et un jours. Aussi, les roues 18a et 18b effectuent chacune librement un tour complet, entraînant avec elles les roues 28a et 28b et les couronnes 28e, 28f et 28g, aucune de ces dernières n'étant retenue. Ainsi, les pièces constitutives du module 28 font une fois encore un tour au cours du mois.January also has thirty-one days. Also, the wheels 18a and 18b each perform a complete turn freely, driving with them the wheels 28a and 28b and the rings 28e, 28f and 28g, none of the latter being retained. Thus, the component parts of module 28 are once again a turn during the month.

Au changement de mois, le module 24 passe de la position correspondant à janvier à celle correspondant à février, la première branche de l'index 24b entraînant de un pas le module 26, à l'exception de l'étoile 26d. Ce dernier module est alors positionné de manière à ce que le sautoir 34 soit engagé et retenu dans la denture extérieure 28j.At the change of months, the module 24 moves from the position corresponding to January to that corresponding to February, the first branch of the index 24b causing step one module 26, with the exception of the star 26d. This latter module is then positioned so that the jumper 34 is engaged and retained in the outer toothing 28j.

Comme, au cours du mois de janvier, les trois couronnes 28e, 28f et 28g ont été entraînées par la roue satellite 28d, cette dernière est prête à entrer en relation avec la couronne 28g, les autres couronnes 28e et 28f étant encore entraînées en rotation. Durant les trois premiers jours, les roues 18a et 18b ne sont pas en prise avec les roues 28a et 28b. Au quatrième jour, et comme la couronne 28g est bloquée, la roue satellite 28d engrène avec l'une des dents intérieures 28m. Comme expliqué plus haut, la roue satellite 28d tourne, entraînant la roue 28c et, avec elle, les roues 28a et 18a. Durant trois jours, la roue 18a avance donc, à chaque jour, de deux pas, armant le ressort 18d.As, during the month of January, the three crowns 28e, 28f and 28g were driven by the satellite wheel 28d, the latter is ready to come into contact with the ring 28g, the other rings 28e and 28f being further rotated. . During the first three days, the wheels 18a and 18b are not engaged with the wheels 28a and 28b. At the fourth day, and as the ring 28g is blocked, the satellite wheel 28d meshes with one of the inner teeth 28m. As explained above, the satellite wheel 28d rotates, driving the wheel 28c and with it the wheels 28a and 18a. For three days, the wheel 18a therefore advances, every day, two steps, arming the spring 18d.

Lorsque vingt-huit jours se sont écoulés, l'index 18c se trouve dans une position telle qu'il entraîne la roue 24d, marquant ainsi le changement de mois. La deuxième branche de l'index 24b fait tourner de un pas le module 26, à l'exception de l'étoile 26d. Le sautoir 34 est alors libéré. En outre, le sautoir 22 est soulevé par la came 24c ce qui permet à la roue 18b de s'aligner sur la roue 18a en faisant un saut équivalent à quatre jours, passant ainsi du vingt-huit février au premier mars. A ce moment-là, les dentures tronquées des roues 18a et 18b sont superposées, et la première dent se trouve en regard respectivement des dents des roues 28a et 28b. En conséquence, durant les trois premiers jours du mois de mars, les roues 28a et 28b sont immobiles.When twenty-eight days have elapsed, the index 18c is in a position such that it drives the wheel 24d, thus marking the change of months. The second branch of the index 24b rotates the module 26 with the exception of the star 26d. The jumper 34 is then released. In addition, the jumper 22 is lifted by the cam 24c which allows the wheel 18b to align with the wheel 18a by making a jump equivalent to four days, thus passing from February 28 to March 1. At this time, the truncated toothings of the wheels 18a and 18b are superimposed, and the first tooth is respectively facing the teeth of the wheels 28a and 28b. As a result, during the first three days of March, the wheels 28a and 28b are stationary.

Au cours du mois de mars, dans un premier temps passent les trois dents tronquées. Ensuite, la roue satellite 28d prend appui sur les dents intérieures 28h, 28i et 28j et fait tourner les couronnes 28e, 28f et 28g, jusqu'à la fin du mois. Lors du passage au mois d'avril, le module 24 est alors entraîné en rotation par l'index 18c, de telle sorte qu'il occupe une position dans laquelle la couronne 28e est bloquée par le sautoir 30.During the month of March, initially, the three truncated teeth pass. Then, the satellite wheel 28d bears on the inner teeth 28h, 28i and 28j and rotates the crowns 28e, 28f and 28g, until the end of the month. During the passage in April, the module 24 is then rotated by the index 18c, so that it occupies a position in which the ring 28 is blocked by the jumper 30.

Comme expliqué plus haut, au début du mois d'avril, les roues 18a et 18b parcourent à nouveau trois pas sans coopérer avec les roues 28a et 28b, à cause des dents tronquées. Ensuite, comme les couronnes 28e, 28f et 28g ont été poussées par la roue satellite 28d en appui contre les dents intérieures 28k, 28l et 28m, et que la couronne 28e est bloquée par le sautoir 30, la roue satellite 28d engrène avec la dent unique 28k, ce qui fait avancer la roue 28a, laquelle entraîne la roue 18a de un pas supplémentaire. De la sorte, l'index 18c, solidaire de la roue 18a, coopère avec le module 24 le trente du mois, le faisant sauter de un pas. Simultanément, le sautoir 22 est soulevé, la roue 18b s'alignant sur la roue 18a, l'aiguille 19 et passant directement du trente au premier.As explained above, at the beginning of April, the wheels 18a and 18b travel three steps again without cooperating with the wheels 28a and 28b, because of the truncated teeth. Then, as the rings 28e, 28f and 28g were pushed by the satellite wheel 28d bearing against the inner teeth 28k, 28l and 28m, and the ring 28e is blocked by the jumper 30, the satellite wheel 28d meshes with the tooth 28k, which advances the wheel 28a, which drives the wheel 18a a step further. In this way, the index 18c, secured to the wheel 18a, cooperates with the module 24 on the thirty of the month, making it jump one step. Simultaneously, the jumper 22 is raised, the wheel 18b aligning with the wheel 18a, the needle 19 and passing directly from the thirty to the first.

Le module 24 occupe alors une position correspondant au mois de mai. Dans cette position, aucun des sautoirs 30, 32 et 34 n'est sollicité. La roue de satellite 28d entraîne ainsi les couronnes 28e, 28f et 28g en rotation. Arrivé au trente et un, l'index 18c fait sauter le module 24 de un pas, de telle sorte qu'il occupe une position correspondant au mois de juin. On retrouve alors une situation correspondant à celle rencontrée en avril. En d'autres termes, le sautoir 30 bloque la couronne 28e, provoquant un saut supplémentaire de un pas des roues 28a et 18a. L'index 18c fait alors sauter le module 24 le trente du mois, le faisant passer de juin à juillet.Module 24 then occupies a position corresponding to the month of May. In this position, none of the jumpers 30, 32 and 34 is solicited. The satellite wheel 28d thus drives the rings 28e, 28f and 28g in rotation. Arrived at thirty-one, the index 18c jumps the module 24 one step, so that it occupies a position corresponding to the month of June. We then find a situation corresponding to that encountered in April. In other words, the jumper 30 blocks the crown 28e, causing an additional jump of a pitch of the wheels 28a and 18a. The index 18c then skips module 24 on the thirty of the month, making it go from June to July.

Le mois de juillet se déroule comme le mois de mai avec, au trente et un, un saut du module 24, qui passe au mois d'août. Au cours de ce mois suivant, aucun sautoir n'est sollicité. La roue de satellite 28d continue donc à faire tourner les trois couronnes 28e, 28f et 28g. Au trente et un, l'index 18c fait sauter le module 24 de un pas, de telle sorte qu'il se trouve en position correspondant au mois de septembre. Dans ce mois encore, c'est le sautoir 30 qui bloque la couronne 28e,. C'est pourquoi, après que les roues 18a et 18b ont fait trois pas sans engrener, elles entraînent ensuite respectivement les roues 28a et 28b, engendrant un saut supplémentaire de la roue 18a, comme cela a été expliqué en rapport avec la situation du mois d'avril.The month of July is like the month of May with, at thirty-one, a jump from module 24, which passes in August. During this next month, no jumper is requested. The satellite wheel 28d therefore continues to rotate the three rings 28e, 28f and 28g. In thirty-one, the index 18c jumps the module 24 one step, so that it is in the position corresponding to the month of September. In this month again, it is the jumper 30 which blocks the 28th crown. This is why, after the wheels 18a and 18b have made three steps without meshing, they then respectively drive the wheels 28a and 28b, generating an additional jump of the wheel 18a, as has been explained in connection with the situation of the month. April.

En octobre, le fonctionnement est le même qu'en juillet, et en novembre le même qu'en avril.In October, the operation is the same as in July, and in November the same as in April.

La situation diffère en février des années bissextiles, le sautoir 32 bloquant alors la couronne 28f, qui ne comporte que deux dents. Cela signifie donc que, la roue 18b sera entraînée de deux pas supplémentaires et non de trois lors des années bissextiles.The situation differs in February leap years, the jumper 32 then blocking the ring 28f, which has only two teeth. This means that wheel 18b will be driven two extra steps and not three during leap years.

On relèvera que le mécanisme tel qu'il vient d'être décrit présente un caractère schématique. Il est évident pour l'homme du métier de le développer de manière à l'adapter aux autres caractéristiques que présente le mouvement auquel il est intégré. De nombreuses variantes peuvent, en outre, être envisagées.It will be noted that the mechanism as just described is schematic. It is obvious to those skilled in the art to develop it so as to adapt it to the other characteristics of the movement in which it is integrated. Numerous variants can, moreover, be envisaged.

Par exemple, le déphasage de la roue 18a en cours de mois pourrait se faire en plus de jours. Ainsi, en munissant les couronnes 28e, 28f et 28g respectivement de deux, quatre et six dents, et les roues 18a et 28a de respectivement soixante deux et cinquante six dents, l'armage du ressort 18d se ferait respectivement en deux, quatre et six jours.For example, the phase shift of the wheel 18a during the month could be done in more days. Thus, by providing the crowns 28e, 28f and 28g respectively with two, four and six teeth, and the wheels 18a and 28a of respectively sixty two and fifty six teeth, the arming of the spring 18d would be respectively in two, four and six days.

La couronne 28g, qui comporte trois dents, pourrait être supprimée, en permettant le blocage des deux couronnes 28e et 28f, tout en garantissant un déphasage de ces dernières lors de l'engagement de leurs sautoirs respectifs.The ring 28g, which has three teeth, could be removed, allowing the locking of the two rings 28e and 28f, while ensuring a phase shift of the latter when engaging their respective jumpers.

Les roues 28a et 28b pourraient également comporter un nombre de dents plus restreint. Il suffit que le module 18 soit entraîné en rotation durant le nombre de jours nécessaire pour assurer la correction au mois de février d'une année bissextile. Dans l'exemple décrit en détail, l'entraînement peut se faire en trois jours. Les roues 28a et 28b pourraient alors être remplacées par des mobiles entraînés à raison de quatre pas par mois, les roues 18a et 18b étant munies de doigts d'entraînement pour assurer cette fonction.The wheels 28a and 28b could also have a smaller number of teeth. It suffices that the module 18 is rotated during the number of days necessary to ensure the correction in February of a leap year. In the example described in detail, the training can be done in three days. The wheels 28a and 28b could then be replaced by driven mobiles at a rate of four steps per month, the wheels 18a and 18b being provided with driving fingers to perform this function.

Le mécanisme tel qu'il vient d'être décrit prend en compte les années bissextiles. Le même principe peut être appliqué à un mécanisme simplifié, appelé annuel. Dans ce cas, le module 26 est supprimé. Le sautoir 34 serait alors commandé par une came de février associée au module 24. Un système de correction pourrait être associé, permettant de commander un recul de un pas de la roue 18a en cours de mois, et assurant ainsi l'ajustement de la date en février des années bissextiles.The mechanism as just described takes into account leap years. The same principle can be applied to a simplified mechanism called annual. In this case, the module 26 is deleted. The jumper 34 would then be controlled by a feeder cam associated with the module 24. A correction system could be associated, making it possible to control a setback of one step of the wheel 18a during the month, and thus ensuring the adjustment of the date in February leap years.

Dans le mécanisme tel que décrit, la roue satellite 28d coopère avec des couronnes montées concentriquement aux roues 28a et 28b. Cette fonction pourrait également être assurée par des sautoirs commandés par les modules 24 et/ou 26, amené ou non dans le chemin de la roue de sautoir 28d et la faisant tourner d'autant de pas que nécessaire pour déphaser les roues 28a et 28b et, avec elles, les roues 18a et 18b.In the mechanism as described, the satellite wheel 28d cooperates with rings concentrically mounted to the wheels 28a and 28b. This function could also be provided by jumpers controlled by the modules 24 and / or 26, brought or not into the path of the jumping wheel 28d and rotating it by as many steps as necessary to phase shift the wheels 28a and 28b and with them, the wheels 18a and 18b.

Ainsi, grâce aux caractéristiques que présente la pièce d'horlogerie selon l'invention, la correction la correction automatique du quantième se fait à raison d'au maximum un pas supplémentaire par mois, ce qui permet de réguler le prélèvement d'énergie.Thus, thanks to the characteristics of the timepiece according to the invention, the correction of the automatic correction of the date is made at a rate of at most one additional step per month, which allows to regulate the energy withdrawal.
