Description

La présente invention se rapporte à un mécanisme de quantième annuel pour mouvement d'horlogerie comprenant un mobile indicateur de quantièmes à trente et une positions en prise une fois par jour avec un mobile d'entraînement en liaison cinématique avec le rouage dudit mouvement d'horlogerie, une came annuelle dont le contour est conformé pour distinguer les mois de 31 jours des autres mois, des moyens pour entraîner cette came à raison d'un tour par année et un mécanisme de correction relié à ladite came annuelle pour faire avancer ledit mobile indicateur d'une position supplémentaire à la fin de chaque mois de moins de 31 jours, ce mécanisme de correction comportant une came de correction en liaison cinématique avec ledit mobile indicateur de quantièmes.The present invention relates to an annual calendar mechanism for a watch movement comprising a date indicator mobile with thirty-one positions engaged once a day with a drive wheel in kinematic connection with the wheelwork of said watch movement. , an annual cam whose contour is shaped to distinguish 31-day months from other months, means for driving this cam at a rate of one turn per year and a correction mechanism connected to said annual cam to advance said mobile indicator an additional position at the end of each month of less than 31 days, this correction mechanism comprising a correction cam in kinematic connection with said mobile date indicator.

On a proposé depuis longtemps ce type de mécanisme de quantième qui constitue un compromis entre le quantième simple et le quantième perpétuel ou semi-perpétuel nécessitant un mécanisme relativement complexe et par conséquent délicat et composé d'un nombre de pièces assez grand, occupant de la place aussi bien en plan qu'en hauteur. Le quantième simple nécessite la remise à la date cinq fois par année, à la fin des mois de moins de 31 jours. Le quantième annuel ne nécessite plus qu'une correction à la fin du mois de février.This type of date mechanism has long been proposed as a compromise between the simple calendar and the perpetual or semi-perpetual calendar requiring a relatively complex and therefore delicate mechanism and composed of a large number of pieces, occupying the place as well in plan as in height. The single date requires the delivery to the date five times a year, at the end of the months of less than 31 days. The annual calendar only needs a correction at the end of February.

Parmi les quantièmes de ce type, on peut citer le CH 583'932 , le CH 684'815 , le CH 685'585 , le EP 756'217 , le CH 581'341 et le EP 987'609 . Tous ces mécanismes ont un changement de quantième traînant, en outre, le passage entre le "30" et le "1" se fait par un saut en deux phases, faisant ainsi apparaître plus ou moins longtemps le "31" entre le "30" et le "1" à la fin des mois de moins de 31 jours. Par ailleurs, certains des mécanismes susmentionnés sont relativement compliqués. On connaît également des mécanismes de quantièmes à saut instantané, mais ceux-ci sont des quantièmes simples.Among the calendars of this type, mention may be made of CH 583'932 , the CH 684'815 , the CH 685'585 , the EP 756,217 , the CH 581'341 and the EP 987'609 . All these mechanisms have a change of trailing date, in addition, the passage between the "30" and the "1" is by a jump in two phases, thus making appear more or less long the "31" between the "30" and the "1" at the end of the months of less than 31 days. In addition, some of the mechanisms mentioned above are relatively complicated. Also known are instant jump date mechanisms, but these are simple dates.

On a encore proposé dans le DE 205445 un mécanisme de calendrier dont l'organe d'entraînement du mobile indicateur des quantièmes est solidaire d'une part, d'un levier de correction en prise avec une came de correction en liaison cinématique avec le mobile indicateur des quantièmes et d'autre part d'un doigt palpeur en prise avec une came annuelle. Dans cette solution l'organe d'entraînement est solidaire du levier de correction, en sorte qu'à chaque entraînement du mobile indicateur des quantièmes, le mécanisme de calendrier doit armer le ressort qui sert à maintenir en prise le doigt palpeur avec la came annuelle. Alors que la correction du mobile des quantièmes n'intervient qu'une fois par mois, le ressort est armé et désarmé chaque jour.It was further proposed in the DE 205445 a calendar mechanism whose date indicator mobile drive member is integral on the one hand, a correction lever engaged with a correction cam in kinematic connection with the date indicator mobile and on the other hand a probe finger engaged with an annual cam. In this solution the drive member is integral with the correction lever, so that each drive of the date indicator mobile, the calendar mechanism must arm the spring which serves to maintain the probe finger in engagement with the annual cam . While correction of the calendar mobile only occurs once a month, the spring is armed and disarmed each day.

Le but de la présente invention est de rendre annuel un mécanisme de quantième simple, de préférence instantané, à l'aide d'une solution ajoutant aussi peu de pièces supplémentaires que possible, garant d'un fonctionnement sûr et d'un faible encombrement.The object of the present invention is to make annual a simple date mechanism, preferably instantaneous, using a solution adding as few additional parts as possible, ensuring a safe operation and a small footprint.

A cet effet, la présente invention a pour objet un mécanisme de quantième du type susmentionné, tel que défini par la revendication 1.For this purpose, the subject of the present invention is a date mechanism of the aforementioned type, as defined by claim 1.

Les avantages principaux de ce mécanisme résident dans sa simplicité et dans son efficacité et sa fiabilité. En dissociant la fonction de correction de celle de l'entraînement quotidien, le ressort utilisé pour la seule correction en fin de mois n'est armé qu'une fois par mois. Avantageusement, ce mécanisme peut être associé à un quantième à saut instantané et permet la correction automatique à la fin des mois de moins de 31 jours de façon également instantanée.The main advantages of this mechanism are its simplicity and its efficiency and reliability. By separating the correction function from that of the daily training, the spring used for the only correction at the end of the month is armed only once a month. Advantageously, this mechanism can be associated with a jump calendar instantaneous and allows the automatic correction at the end of the months of less than 31 days so also instantaneous.

Des particularités et des avantages spécifiques apparaîtront au cours de la description qui va suivre, ainsi qu'à l'aide des dessins annexés qui l'accompagnent, illustrant, schématiquement et à titre d'exemple, une forme d'exécution ainsi qu'une variante du mécanisme de quantième objet de la présente invention.

Le mécanisme de quantième illustré par les figures 1 à 5 comporte un mobile annulaire 1 portant les quantièmes de 1 à 31. Ce mobile annulaire 1, plus généralement appelé disque des quantièmes comporte une denture interne habituelle 1b et est solidaire d'une came de correction annulaire 1a.The date mechanism illustrated by the Figures 1 to 5 comprises an annular mobile 1 carrying the dates of 1 to 31. This annular mobile 1, more generally called date disc has a usual internal toothing 1b and is integral with an annular correction cam 1a.

La denture 1b est en prise d'une part avec un sautoir de positionnement 2 (figure 6) et d'autre part avec un doigt d'entraînement 3 solidaire d'une came de saut instantané 4 concentrique à une roue d'entraînement 5. Une ouverture en arc de cercle 5a solidaire de la roue d'entraînement 5 et une cheville 4a solidaire de la came de saut instantané 4 servent à rendre cette came solidaire de la roue d'entraînement, mais avec un certain jeu angulaire dont le rôle sera expliqué par la suite. Un galet 6a d'une bascule 6 pour le changement instantané des quantièmes, est pressé contre le pourtour de la came de saut instantané 4 par un ressort 7.The toothing 1b is engaged on the one hand with a positioning jumper 2 ( figure 6 ) and on the other hand with a drive finger 3 integral with an instantaneous jump cam 4 concentric with a drive wheel 5. An opening in a circular arc 5a integral with the drive wheel 5 and a pin 4a integral with the instantaneous jump cam 4 serve to make this cam integral with the drive wheel, but with a certain angular clearance whose role will be explained later. A roller 6a of a rocker 6 for the instantaneous change of dates, is pressed against the periphery of the instantaneous jump cam 4 by a spring 7.

Dans cette forme d'exécution, un second doigt 3a est destiné à entraîner une étoile des jours de la semaine 17 à sept bras, une fois par jour en même temps que le disque des quantièmes 1. L'invention n'est cependant pas limitée à la présence de cette étoile des jours 17, le mécanisme selon l'invention ne pouvant comporter que l'indication des quantièmes.In this embodiment, a second finger 3a is intended to drive a star of the weekdays 17 to seven arms, once a day at the same time as the date disc 1. The invention is however not limited at the presence of this day star 17, the mechanism according to the invention can only include the indication of the dates.

Le mécanisme qui vient d'être décrit est celui d'un quantième instantané simple. Nous allons maintenant décrire la partie du mécanisme qui permet de passer d'un quantième simple à un quantième annuel, tout en restant instantané, au moins pour l'essentiel, c'est-à-dire du 1er au 30 du mois. Comme indiqué précédemment, le disque des quantièmes est solidaire d'une came de correction annulaire 1a contre laquelle une bascule de correction 8 munie d'un galet 8a est appliquée par un ressort 9. Cette came de correction 1a comporte une longue rampe circulaire 1a' destinée à armer le ressort 9 de la bascule de correction. Cette rampe annulaire 1a' s'étend sur un angle d'à peu près 348° (30/31ème), en s'éloignant progressivement du centre de rotation du disque de quantième et se termine par une courbe concave 1a* reliant la fin au début de la longue rampe circulaire et qui s'étend sur à peu près 12°. Cette courbe concave 1a* permet à la bascule 8 pressée par le ressort 9 de faire avancer le disque des quantièmes d'un pas grâce à l'énergie emmagasinée par le ressort 9. A noter que la forme de courbe concave 1a* reliant les deux extrémités de la rampe circulaire 1a' n'est pas indispensable au fonctionnement du mécanisme de correction automatique et pourrait être remplacée par une simple rampe rectiligne.The mechanism that has just been described is that of a simple instantaneous calendar. We now describe the part of the mechanism to move from a simple calendar with an annual calendar, while remaining instantaneous, at least in essence, that is to say from 1 to 30 of this month. As indicated above, the date disk is integral with an annular correction cam 1a against which a correction lever 8 provided with a roller 8a is applied. by a spring 9. This correction cam 1a comprises a long circular ramp 1a 'for arming the spring 9 of the correction lever. This annular ramp 1a 'extends over an angle of approximately 348 ° (30/31 th), gradually away from the rotational center of the date-disc and terminates in a concave curve connecting the end 1a * at the beginning of the long circular ramp, which extends for about 12 °. This concave curve 1a * allows the rocker 8 pressed by the spring 9 to advance the date disc by a step thanks to the energy stored by the spring 9. Note that the concave curve shape 1a * connecting the two ends of the circular ramp 1a 'is not essential to the operation of the automatic correction mechanism and could be replaced by a simple straight ramp.

En face de la jonction entre la courbe concave 1a* et le début de la rampe circulaire 1a', le bord interne de la came de correction 1a porte une dent, un doigt, ou une saillie 10, destinée à venir en prise à chaque rotation du disque des quantièmes 1 avec une étoile de correction 11 en prise avec un sautoir de positionnement 12 pressé par un ressort 13.Opposite the junction between the concave curve 1a * and the beginning of the circular ramp 1a ', the inner edge of the correction cam 1a carries a tooth, a finger, or a projection 10, intended to come into engagement with each rotation of the date disc 1 with a correction star 11 in engagement with a positioning jumper 12 pressed by a spring 13.

Cette étoile de correction 11 est solidaire d'un renvoi 14 engrenant avec un renvoi 15, lui-même en prise avec un mobile indicateur des mois 16, concentrique à l'étoile des jours 17. Une came annuelle circulaire 18 est concentrique au renvoi 15. Elle comporte une cheville 18a en prise avec une ouverture en arc de cercle 15a du renvoi 15. Un ressort 19 dont une extrémité est solidaire du renvoi 15 et dont l'autre est solidaire de la came annuelle circulaire 18 tend à maintenir la cheville 18a contre l'extrémité gauche de l'ouverture 15a. La came annuelle circulaire 18 est divisée angulairement en douze secteurs égaux, chaque secteur correspondant à un mois de l'année. Les mois de 31 jours correspondent aux parties de grand diamètre 18' de la came 18, alors que les cinq mois de moins de 30 jours correspondent aux parties de petit diamètre 18* formant ainsi cinq creux dans la partie de grand diamètre 18' de la came annuelle 18.This correction star 11 is integral with a reference 14 meshing with a reference 15, itself in engagement with a moving indicator month 16, concentric with the star of the days 17. A circular annual cam 18 is concentric with the reference 15 It comprises a pin 18a engaged with an opening 15 in the arc 15a of the reference 15. A spring 19 whose one end is integral with the reference 15 and the other is integral with the circular annual cam 18 tends to maintain the pin 18a against the left end of the opening 15a. The circular annual cam 18 is divided angularly into twelve equal sectors, each corresponding sector at one month of the year. The 31-day months correspond to the large diameter portions 18 'of the cam 18, while the five months of less than 30 days correspond to the small diameter portions 18 * thereby forming five depressions in the large diameter portion 18' of the annual cam 18.

La bascule de correction 8 présente un doigt 8b qui est destiné à coopérer avec la came annuelle 18 à la fin de chaque mois comme on va l'expliquer maintenant. Comme on le voit sur la figure 1 correspondant au 30 août, le galet 8a de la bascule de correction 8 arrive vers l'extrémité de la rampe circulaire 1a' de la came 1a. Le doigt 8b de la bascule de correction 8 se trouve en face d'une partie de grand diamètre 18' de la came annuelle 18. En passant du 30 au 31 (figure 2), on peut remarquer que le galet 8a de la bascule de correction 8 a dépassé l'extrémité de la rampe circulaire 1a' de la came de correction 1a, mais la partie de grand diamètre 18' de la came annuelle 18 qui se trouve en face du doigt 8b empêche la bascule 8 de descendre le long de la courbe concave 1a* de la came de correction 1a. De ce fait, le passage du 31 août au 1er septembre s'effectue normalement à l'aide du doigt d'entraînement 3 solidaire de la came de saut instantané 4, comme on le voit sur la figure 3.The correction flip-flop 8 has a finger 8b which is intended to cooperate with the annual cam 18 at the end of each month as will be explained now. As we see on the figure 1 corresponding to August 30, the roller 8a of the correction lever 8 arrives towards the end of the circular ramp 1a 'of the cam 1a. The finger 8b of the correction lever 8 is in front of a large-diameter portion 18 'of the annual cam 18. By changing from 30 to 31 ( figure 2 ), it may be noted that the roller 8a of the correction lever 8 has passed the end of the circular ramp 1a 'of the correction cam 1a, but the large diameter portion 18' of the annual cam 18 which is in position. finger face 8b prevents the rocker 8 from going down along the concave curve 1a * of the correction cam 1a. Therefore, the transition from August 31 to September 1, is normally carried out using the driving pin 3 integral with the cam instantaneous jump 4, as seen on the figure 3 .

Au cours de ce passage du 31 au 1er du mois suivant, le galet 8a de la came de correction 8 est passé de la fin au début de la rampe circulaire 1a' de la came de correction 1a. Simultanément, le doigt 10 de cette came de correction 1a entraîne l'étoile de correction 11 d'un pas. Etant donné que le renvoi 14 est solidaire de l'étoile de correction 11, le renvoi 15 et le mobile indicateur des mois 16 sont entraînés simultanément à l'étoile de correction 11. Cette rotation permet au doigt 8b de la bascule de correction 8 de pénétrer entre deux parties de grand diamètre 18' de la came de correction 18, correspondant à un mois de moins de 31 jours, ici le mois de septembre. Comme à chaque changement de quantième, le doigt 3a fait tourner l'étoile des jours 17.During this passage from the 31st to the 1st of the following month, the roller 8a of the correction cam 8 has passed from the end to the beginning of the circular ramp 1a 'of the correction cam 1a. Simultaneously, the finger 10 of this correction cam 1a drives the correction star 11 by one step. Since the reference 14 is secured to the correction star 11, the reference 15 and the indicator mobile of the months 16 are simultaneously driven to the correction star 11. This rotation allows the finger 8b of the correction lever 8 to penetrate between two large diameter portions 18 'of the correction cam 18, corresponding to one month less than 31 days, here the month of September. As with each change of date, the finger 3a rotates the star of days 17.

Les figures 4 et 5 montrent le passage du 30 septembre au 1er octobre. Sur la figure 4, la bascule de correction 8 et la came de correction occupent la même position que sur la figure 1, mais la came annuelle 18 est disposée en sorte qu'un creux situé entre deux parties de grand diamètre 18' se trouve vis-à-vis du doigt 8b de la bascule de correction. Par conséquent, lors du prochain entraînement du disque des quantièmes 1, le 30 septembre à minuit, le doigt 3 déplace normalement le disque des quantièmes d'un pas, amenant ainsi le galet 8a de la bascule de correction dans la position illustrée par la figure 2, mais étant donné que le doigt 8b de la bascule de correction 8 se trouve en face d'une partie de petit diamètre 18* de la came annuelle 18, le ressort 9 pousse cette bascule de correction 8 et son doigt 8b dans le creux de la came annuelle 18, en sorte qu'au cours de ce basculement effectué sous la pression du ressort 9, le galet 8a glisse le long de la courbe concave 1a* de la came de correction 1a qui déplace le disque de quantième 1 d'un second pas pour l'amener à afficher le 1er octobre.The figures 4 and 5 show the passage from 30 September to 1 October. On the figure 4 , the correction lever 8 and the correction cam occupy the same position as on the figure 1 , but the annual cam 18 is arranged so that a recess located between two large diameter portions 18 'is vis-à-vis the finger 8b of the correction flip-flop. Consequently, during the next drive of the date disk 1, September 30 at midnight, the finger 3 normally moves the date disk by one step, thus bringing the roller 8a of the correction lever into the position illustrated by FIG. figure 2 , but since the finger 8b of the correction lever 8 is opposite a small diameter portion 18 * of the annual cam 18, the spring 9 pushes this correction lever 8 and its finger 8b into the hollow of the annual cam 18, so that during this tilting performed under the pressure of the spring 9, the roller 8a slides along the concave curve 1a * of the correction cam 1a which moves the date disk 1 of a second step to get it to show on October 1 st .

Au cours de ce second pas, immédiatement consécutif au premier pas du disque des quantièmes 1, l'étoile de correction 11 est déplacée d'un pas en même temps que les renvois 14 et 15 et le mobile des mois 16. Etant donné que le doigt 8b de la bascule de correction 8 est engagé dans un creux de la came annuelle 18, celle-ci ne peut pas tourner. C'est la raison pour laquelle la came annuelle 18 reste immobile et l'ouverture en arc de cercle 15a ménagée dans le renvoi 15 permet un déplacement angulaire relatif entre ce renvoi 15 et la came annuelle 18. Au cours du mois suivant, la bascule de correction 8 est progressivement soulevée par la rampe circulaire 1a' de la came de correction 1a. Une fois que le doigt 8b de cette bascule est complètement sorti du creux de la came annuelle 18, le ressort 19 ramène la cheville 18a de la came annuelle 18 en butée contre l'autre extrémité de l'ouverture en arc de cercle 15a du renvoi 15, en sorte que l'extrémité du doigt 8b de la bascule 8 se retrouve alors en face d'une partie de grand diamètre 18' de la came annuelle 18, la mettant hors d'action le 31 octobre comme on l'a expliqué ci-dessus lors du passage du 30 au 31 août.During this second step, immediately following the first step of the date disk 1, the correction star 11 is moved by one step at the same time as the referrals 14 and 15 and the mobile of the months 16. Since the finger 8b of the correction lever 8 is engaged in a hollow of the annual cam 18, it can not turn. This is the reason why the annual cam 18 remains stationary and the opening in an arc 15a formed in the reference 15 allows a relative angular displacement between this reference 15 and the annual cam 18. During the following month, the rocker correction 8 is gradually raised by the ramp circular 1a 'of the correction cam 1a. Once the finger 8b of this rocker is completely out of the hollow of the annual cam 18, the spring 19 brings back the pin 18a of the annual cam 18 abuts against the other end of the arcuate opening 15a of the return 15, so that the end of the finger 8b of the latch 8 is then found in front of a large diameter portion 18 'of the annual cam 18, putting it out of action October 31 as explained above during the transition from August 30 to 31.

Dans l'exemple décrit ci-dessus, lors du passage du disque des quantièmes du 31 au 1er du mois suivant, le doigt 8b de la bascule 8 tombe dans un creux 18* de la came annuelle 18. Suivant la pression exercée par le ressort 9 de la bascule de correction 8, le frottement entre le doigt 8b de la bascule 8 et la partie 18' de la came annuelle peut être supérieur au couple développé par le ressort 19, en sorte qu'au lieu de tomber tout de suite dans le creux 18* de la came annuelle 18, le doigt 8b restera sur la partie de grand diamètre 18' de la came 18 pendant que le renvoi 15 est entraîné par le doigt 10, l'étoile 11 et le renvoi 14, armant ainsi le ressort 19. Dès que la rampe 1a' de la came de correction 1a aura soulevé suffisamment la bascule 8 au cours du mois suivant, la came annuelle 18 sera déplacée angulairement d'un pas dans le sens des aiguilles de la montre par la détente du ressort 19, en sorte que le doigt 8b de la bascule 8 tombera alors dans un creux 18* de la came annuelle 18, correspondant à un mois de moins de 31 jours.In the example described above, during the passage of the date disc 31 to the 1st of the following month, the finger 8b of the latch 8 falls into a recess 18 * of the annual cam 18. According to the pressure exerted by the spring 9 of the correction lever 8, the friction between the finger 8b of the flip-flop 8 and the portion 18 'of the annual cam may be greater than the torque developed by the spring 19, so that instead of falling right away in the hollow 18 * of the annual cam 18, the finger 8b will remain on the large-diameter portion 18 'of the cam 18 while the return 15 is driven by the finger 10, the star 11 and the reference 14, thus arming the spring 19. As soon as the ramp 1a 'of the correction cam 1a has sufficiently raised the rocker 8 during the following month, the annual cam 18 will be moved angularly by one step in the direction of the clockwise by the trigger of the spring 19, so that the finger 8b of the rocker 8 will then fall into a hollow 18 * d e the annual cam 18, corresponding to a month of less than 31 days.

Dans la forme d'exécution du quantième instantané décrit ci-dessus, l'ouverture 5a ménagée dans la roue d'entraînement 5 du quantième, dans laquelle la cheville 4a de la came de saut instantané 4 est engagée, permet un déplacement angulaire relatif d'un pas entre cette came 4 et la roue d'entraînement 5, en liaison cinématique avec le rouage indicateur de la pièce d'horlogerie, afin de permettre le saut instantané du disque de quantième 1. Après le saut de ce disque de quantième, le doigt d'entraînement 3 solidaire de la came de saut instantané 4 se trouve entre deux dents de la denture 1b et puisque la cheville 4a de la came 4 s'est déplacée durant le saut à l'autre extrémité de l'ouverture en arc de cercle 5a de la roue d'entraînement 5, elle garantit que le disque de quantième 1 ne peut pas sauter de plus d'un pas, le doigt d'entraînement 3 jouant alors le rôle d'organe de verrouillage.In the embodiment of the instantaneous calendar described above, the opening 5a formed in the drive wheel 5 of the date, in which the pin 4a of the instantaneous jump cam 4 is engaged, allows a relative angular displacement of a step between this cam 4 and the drive wheel 5, in kinematic connection with the gear train indicator of the timepiece, to allow the instantaneous jump of the date disc 1. After the jump of this date disc, the drive finger 3 integral with the instantaneous jump cam 4 is between two teeth of the date disk. 1b teeth and since the pin 4a of the cam 4 has moved during the jump at the other end of the arcuate opening 5a of the drive wheel 5, it ensures that the date disc 1 can not not jump more than one step, the drive finger 3 then playing the role of locking member.

Le mécanisme de quantième annuel, dans cette version sera instantané, mais le passage du 30 au 1er, dans le cas d'un mois de 30 jours, se fera en deux temps, le 31 étant affiché durant un certain temps, jusqu'à ce que la roue d'entraînement avance et fasse sortir le doigt 3 de la denture 1b du disque des quantièmes 1.The annual calendar mechanism, in this version will be instantaneous, but the passage of 30 to 1, in the case of a 30-day month, will be in two stages, 31 being displayed for a time, until the drive wheel advances and causes the finger 3 to come out of the toothing 1b of the date disk 1.

La figure 6 illustre une variante qui permet d'éviter ce passage du 30 au 1er en deux temps. A cet effet, le disque des quantièmes 1 est monté pivotant sur trois galets de guidage 20a, 20b, 20c montés pivotants sur la platine P portant le mécanisme calendrier, de part et d'autre de l'extrémité du sautoir de positionnement 2 du disque de quantièmes 1 qui est en contact avec la denture 1b de ce disque 1, en sorte que ce sautoir 2 pressé par un ressort 2a formé par un bras élastique venu d'une pièce avec lui, applique ce disque de quantième 1 contre ces galets de guidage 20 en le guidant autour d'un axe virtuel coïncidant avec le centre de ce disque de quantième 1. On a montré par une flèche F1 le moment de force résultant de la pression du cliquet 2 sur une dent 1b du disque de quantième 1 par rapport au galet de guidage 20a. On a montré par ailleurs par la flèche F2 le moment de force résultant de la bascule de correction 8 pressée par le ressort 9 contre la courbe concave 1a* de la came de correction 1a par rapport à ce même galet de guidage 20a. On voit que ce moment de force F2 dont le bras de levier est sensiblement supérieur à celui du moment de force F1 développe un couple plus élevé et de sens opposé à celui du moment de force F1, en sorte qu'il est apte à faire basculer le disque des quantième 1 par rapport au galet 20a comme illustré en traits mixtes sur la figure 6.The figure 6 illustrates an alternative that avoids the passage of 30 to 1 in two steps. For this purpose, the date disk 1 is pivotally mounted on three guide rollers 20a, 20b, 20c pivotally mounted on the plate P carrying the calendar mechanism, on either side of the end of the positioning pin 2 of the disk of date 1 which is in contact with the toothing 1b of this disc 1, so that this jumper 2 pressed by a spring 2a formed by an elastic arm from a piece with him, applies this date disc 1 against these rollers of guide 20 guiding it around a virtual axis coinciding with the center of the date disc 1. It has been shown by an arrow F 1 the moment of force resulting from the pressure of the pawl 2 on a tooth 1b of the date disc 1 relative to the guide roller 20a. F 2 has also shown the moment of force resulting from the correction lever 8 pressed by the spring 9 against the concave curve 1a * of the correction cam 1a relative to the same guide roller 20a. It can be seen that this moment of force F 2 whose lever arm is substantially greater than that of the moment of force F 1 develops a higher torque in the opposite direction to that of the moment of force F 1 , so that it is suitable to tilt the disk of the date 1 relative to the roller 20a as shown in phantom on the figure 6 .

Un quatrième galet 20d situé à une certaine distance du bord du disque des quantièmes 1 sert de butée pour limiter le basculement du disque des quantièmes 1. Ce basculement permet à la denture 1b du disque des quantièmes 1 de s'écarter du doigt 3 après le saut du 30 au 31 lors du passage du 30 au 1er, en sorte que ce saut de deux pas du disque de quantièmes devient alors instantané tout en maintenant le verrouillage destiné à empêcher le saut de deux quantièmes dans les autres cas.A fourth roller 20d located at a distance from the edge of the date disk 1 serves as a stop to limit the tilting of the date disk 1. This tilting allows the teeth 1b of the date disk 1 to deviate from the finger 3 after the jump from 30 to 31 during the passage of 30 to 1, so that the jump of two steps of the date ring becomes instant while maintaining the latch for preventing the jumping of two dates in the other cases.

On peut encore constater sur la figure 5 que le ressort 9 pressant la bascule contre les cames de correction 1a et annuelle 18 est un ressort à deux bras dont l'un appuie sur la bascule de correction 8, tandis que l'autre appuie sur une tirette 21 de mise à l'heure et de mise à la date du mécanisme de remontage et de mise à l'heure. Normalement, cette tirette 21 est dans la position illustrée en traits mixtes sur la figure 5, position dans laquelle la tige de remontoir 22 occupe une position axiale poussée vers le centre du mouvement d'horlogerie. Lorsque l'on tire cette tirette vers l'extérieur pour l'amener dans la position dessinée en trait continu sur la figure 5, correspondant à la position de mise à la date et de mise à l'heure, on peut constater que le bras du ressort 9 qui appuie sur la tirette se déplace d'un angle substantiel par rapport au bras de ce même ressort 9 qui appuie sur la bascule de correction 8, diminuant sensiblement la pression du ressort sur cette bascule de correction 8, facilitant les opérations de correction de la date et de mise à l'heure et améliorant la sécurité du fonctionnement pendant cette opération, en réduisant la pression de la bascule 8 sur la came de correction 1a du disque des quantièmes 1.We can still see on the figure 5 that the spring 9 pressing the rocker against the correction cams 1a and annual 18 is a spring with two arms, one presses the correction lever 8, while the other presses a zipper 21 for setting the time and setting the date of the winding and setting mechanism. Normally, this pull tab 21 is in the position shown in phantom on the figure 5 position in which the winding stem 22 occupies an axial position pushed towards the center of the watch movement. When pulling this pull outward to bring it into the position drawn in solid lines on the figure 5 , corresponding to the setting position on the date and time setting, it can be seen that the arm of the spring 9 which presses on the pull tab moves at a substantial angle with respect to the arm of the same spring 9 which supports on the correction lever 8, substantially decreasing the spring pressure on this correction flip-flop 8, facilitating the date correction and time-setting operations and improving the safety of operation during this operation, by reducing the pressure of the flip-flop 8 on the correction cam 1a of the date disc 1.

Comme on a pu le constater à la lecture de la description qui précède, le mécanisme de calendrier annuel selon la présente invention est extrêmement simple, puisqu'il ne comporte qu'une came de correction 1a, une bascule de correction 8, une came annuelle 18 qui neutralise ou non l'action de la came de correction 1a et une étoile d'entraînement 11 de cette came annuelle 18. Cette simplicité est garante de la fiabilité du mécanisme, tous les organes étant constitués par des organes dentés à l'exception de la bascule de correction 8 nécessaire pour effectuer le pas supplémentaire à la fin des mois de moins de 31 jours et qui permet de rendre cette correction instantanée.As can be seen from reading the foregoing description, the annual calendar mechanism according to the present invention is extremely simple, since it comprises only a correction cam 1a, a correction flip-flop 8, an annual cam 18 which neutralizes or not the action of the correction cam 1a and a drive star 11 of the annual cam 18. This simplicity guarantees the reliability of the mechanism, all members being constituted by toothed members with the exception the correction flip-flop 8 required to perform the additional step at the end of the months of less than 31 days and which makes this correction instantaneous.

Ce mécanisme occupe peu de place aussi bien en plan qu'en hauteur. Bien que l'on ait décrit un quantième annuel associé à un mécanisme à saut instantané, cette invention est évidemment applicable à d'autres mécanisme de quantièmes à saut semi-instantané ou à changement de quantième traînant. De même comme on a pu le constater, cette invention s'applique aussi à un calendrier indiquant le quantième, le jour et le mois, comme à un quantième seul ou à un calendrier indiquant le quantième et le jour.This mechanism occupies little space both in plan and height. Although we have described an annual calendar associated with an instantaneous jump mechanism, this invention is obviously applicable to other semi-instantaneous date or trailing calendar change date mechanism mechanisms. Similarly, as we have seen, this invention also applies to a calendar indicating the date, the day and the month, as a single calendar or a calendar indicating the date and the day.
