Abstract

The annual date mechanism for a clock movement includes a correction cam (1a) which is linked to the indicator. This includes a portion comprising a correction balance, which is designed to advance the date by one step from 31 to 1 at the end of the month. The correction balance is spring biased. The annual date display mechanism includes a correction cam (1a) in mechanical linkage with a mobile date indicator (1). The correction cam is annular in shape, and is concentric with the mobile date indicator. A correction balance (8) is in contact on the one hand with the correction cam (1a), and on the other hand with an annual cam (18). A spring (9) presses the correction balance (8) against the cams (1a, 18). The correction cam (1a) comprises a portion (1a) to arm the spring (9), followed by a portion (1aasterisk) of a size to cause the displacement of the date wheel indicator (1) by one step between the 31 and the 1 under the pressure of the spring (9).

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'entraínement 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 entraíner 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.The present invention relates to a mechanism for annual calendar for watch movement including a mobile date indicator at thirty-one positions in taken once a day with a training mobile in kinematic link with the train of said clockwork movement, an annual cam whose contour is shaped to distinguish the 31-day months from other months, means to train this cam at the rate of one turn per year and one correction mechanism connected to said annual cam for advancing said mobile indicator by an additional position at the end of each month less than 31 days.

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 mechanism has been proposed for a long time calendar which is 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 fairly large number of parts, occupying the place both in plan and in height. The simple calendar requires resetting to the date five times a year, at the end months less than 31 days. The annual calendar does not require more than 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 traínant, en outre, le passage entre le "30" et le "1" se fait par un saut en deux phases, faisant ainsi apparaítre 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 connaít également des mécanismes de quantièmes à saut instantané, mais ceux-ci sont des quantièmes simples. Among the calendars of this type, there may be mentioned the CH 583'932, CH 684'815, CH 685'585, EP 756'217, CH 581,341 and EP 987,609. All of these mechanisms have changed trailing calendar, in addition, the passage between the "30" and the "1" is made by a jump in two phases, making thus appear more or less long the "31" between the "30" and the "1" at the end of months of less than 31 days. Through elsewhere, some of the aforementioned mechanisms are relatively complicated. We also know the mechanisms of instantaneous jump dates, but these are dates Simple.

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 purpose of the present invention is to make an annual simple date mechanism, preferably instantaneous, with using a solution adding as few extra pieces as possible, ensuring safe operation and 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.To this end, 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. 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 lie in its simplicity and in its efficiency and reliability. advantageously, this mechanism can be associated with a date at instant jump and allows automatic correction at the end months of less than 31 days also instantly.

    • 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 in Figures 1 to 5 comprises an annular mobile 1 carrying the date of 1 to 31. This annular mobile 1, more generally called disc of the dates 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'entraínement 3 solidaire d'une came de saut instantané 4 concentrique à une roue d'entraínement 5. Une ouverture en arc de cercle 5a solidaire de la roue d'entraínement 5 et une cheville 4a solidaire de la came de saut instantané 4 servent à rendre cette came solidaire de la roue d'entraínement, 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.Tooth 1b is engaged on the one hand with a jumper positioning 2 (Figure 6) and secondly with a finger drive 3 secured to an instantaneous jump cam 4 concentric with a drive wheel 5. An opening in circular arc 5a integral with the drive wheel 5 and a pin 4a secured to the instantaneous jump cam 4 are used to make this cam integral with the drive wheel, but with a certain angular play whose role will be explained later. A roller 6a of a rocker 6 for the instantaneous change of dates, is pressed against the around the instantaneous jump cam 4 by a spring 7.

    Dans cette forme d'exécution, un second doigt 3a est destiné à entraíner 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 train a star on weekdays 17 through seven arms, once a day at the same time as the disc of 1. The invention is not however limited to the presence of this 17 day star, the mechanism according to the invention can only include the indication of 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 which has just been described is that of a simple instantaneous calendar. We will now describe the part of the mechanism which makes it possible to pass from a simple calendar to an annual calendar, while remaining instantaneous, at least for the most part, that is to say from the 1st to the 30th of the month. As indicated above, the date disc 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 has a long circular ramp 1a ' intended to arm the spring 9 of the correction lever. This annular ramp 1a 'extends over an angle of approximately 348 ° (30/31 th ), gradually moving away from the center of rotation of the date disc and ends with a concave curve 1a * connecting the end at the beginning of the long circular ramp which extends over approximately 12 °. This concave curve 1a * allows the rocker 8 pressed by the spring 9 to advance the disc by the date by one step thanks to the energy stored by the spring 9. Note that the shape of the concave curve 1a * connecting the two ends of the circular ramp 1a 'is not essential for 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 internal 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 taken 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 engaged with a mobile month indicator 16, concentric with the star of days 17. A circular annual cam 18 is concentric to reference 15. It includes an ankle 18a engaged with an opening in an arc 15a of the reference 15. A spring 19 one end of which is integral with the reference 15 and whose the other is integral with the circular annual cam 18 tends to hold the ankle 18a against the left end of opening 15a. The circular annual cam 18 is divided angularly in twelve equal sectors, each corresponding sector to a month of the year. The 31-day months correspond to the large diameter parts 18 ′ of the cam 18, whereas the five months of less than 30 days correspond to small diameter parts 18 * thus forming five hollows 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'entraínement 3 solidaire de la came de saut instantané 4, comme on le voit sur la figure 3.The correction lever 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 seen in 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 scale 8 is located opposite a large diameter portion 18 ′ of the annual cam 18. Going from 30 to 31 (FIG. 2), it can be noted that the roller 8a of the scale of correction 8 has exceeded 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 opposite the finger 8b prevents the rocker 8 from descending along the concave curve 1a * of the correction cam 1a. Therefore, the transition from August 31 to September 1, is normally carried out with the drive finger 3 secured to the cam instantaneous jump 4, as seen in 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 entraíne 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 entraínés 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 start 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 integral with the correction star 11, the reference 15 and the month indicator mobile 16 are driven simultaneously with the correction star 11. This rotation allows the finger 8b of the correction lever 8 to penetrate between two large diameter parts 18 ′ of the correction cam 18, corresponding to a month of less than 31 days, here the month of September. As with each change of date, finger 3a rotates the day star 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 entraínement 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 le 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.Figures 4 and 5 show the transition from 30 September to 1 October. In FIG. 4, the correction lever 8 and the correction cam occupy the same position as in FIG. 1, but the annual cam 18 is arranged so that a recess situated between two large diameter parts 18 ′ is located -with finger 8b of the correction rocker. Consequently, during the next training of the date disc 1, on September 30 at midnight, finger 3 normally moves the date disc by one step, thus bringing the roller 8a of the correction lever in the position illustrated in the figure. 2, but since the finger 8b of the correction lever 8 is located 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 effected under the pressure of the spring 9, the roller 8a slides along the concave curve 1a * of the correction cam 1a which displaces the date disc 1 by a second step to bring it to display on October 1.

    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 disc 1, the correction star 11 is moved one step at the same time as the references 14 and 15 and the mobile for months 16. Since the finger 8b of the correction lever 8 is engaged in a hollow of the annual cam 18, this cannot rotate. It's here reason why the annual cam 18 remains stationary and the opening in a circular arc 15a formed in the reference 15 allows relative angular displacement between this reference 15 and the annual cam 18. During the following month, the scale 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 in abutment against the other end of the opening in a circular arc 15a of the reference 15, so that the end of the finger 8b of the rocker 8 is then found in face of a large diameter portion 18 'of the annual cam 18, putting it out of action on October 31 as explained above during the passage 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 entraíné 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 from the 31st to the 1st of the following month, the finger 8b of the rocker 8 falls into a recess 18 * of the annual cam 18. Depending on the pressure exerted by the spring 9 of the correction lever 8, the friction between the finger 8b of the lever 8 and the part 18 'of the annual cam can be greater than the torque developed by the spring 19, so that instead of falling straight 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 reference 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 raised the rocker 8 sufficiently during the following month, the annual cam 18 will be angularly moved one step clockwise by the trigger 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'entraínement 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'entraínement 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'entraínement 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'entraínement 5, elle garantit que le disque de quantième 1 ne peut pas sauter de plus d'un pas, le doigt d'entraínement 3 jouant alors le rôle d'organe de verrouillage.In the embodiment of the snapshot date 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 movement relative angularity of a step between this cam 4 and the drive wheel 5, in kinematic connection with the train indicator of the timepiece, to allow the instantaneous jump to the date disc 1. After the jump to this date disc, the drive finger 3 secured of the instantaneous jump cam 4 is between two teeth of the teeth 1b and since the pin 4a of the cam 4 moved during the jump to the other end of the opening in an arc 5a of the drive wheel 5, it guarantees that the date disc 1 cannot jump more than one step, the training finger 3 then playing the role of locking device.

    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'entraínement 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 from 30 to 1 st , in the case of a month of 30 days, will be done in two stages, the 31 being displayed for a certain time, until that the drive wheel advances and brings out the finger 3 of the teeth 1b of the date disc 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.FIG. 6 illustrates a variant which makes it possible to avoid this transition from 30 to 1 st in two stages. To this end, the date disc 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 jumper 2 of the disc of dates 1 which is in contact with the teeth 1b of this disc 1, so that this jumper 2 pressed by a spring 2a formed by an elastic arm come in one piece with it, applies this date disc 1 against these rollers guide 20 by guiding it around a virtual axis coinciding with the center of this date disc 1. We have 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. The arrow 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 with respect to this same guide roller 20a. It can be seen that this moment of force F 2 , the lever arm of which is substantially greater than that of the moment of force F 1 develops a higher torque and in the opposite direction to that of the moment of force F 1 , so that it is suitable to tilt the date disc 1 relative to the roller 20a as illustrated in dashed lines in FIG. 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 certain distance from the edge of the date disc 1 serves as a stop to limit the tilting of the date disc 1. This tilting allows the teeth 1b of the date disc 1 to move away from the finger 3 after the jump from 30 to 31 during the transition from 30 to 1 st , so that this jump of two steps of the date disc then becomes instantaneous while maintaining the locking intended to prevent the jump 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 in Figure 5 that the spring 9 pressing the rocker against the correction cams 1a and annual 18 is a spring with two arms, one of which presses correction flip-flop 8, while the other presses a zipper 21 for setting the time and setting the date of winding and time setting mechanism. Normally, this zipper 21 is in the position illustrated in lines mixed in Figure 5, position in which the rod winder 22 occupies an axial position pushed towards the center of the watch movement. When we pull this pull outwards to bring it into the drawn position in solid lines in FIG. 5, corresponding to the date and time setting position, you can note that the spring 9 arm which presses on the pull tab moves at a substantial angle to the arm of this same spring 9 which presses on the correction lever 8, significantly reducing the spring pressure on this correction scale 8, facilitating correction operations date and time setting and improving security of operation during this operation, reducing the pressure of rocker 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'entraínement 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 we saw on reading the description above, the annual calendar mechanism according to the present invention is extremely simple, since it does not include that a correction cam 1a, a correction rocker 8, an annual cam 18 which neutralizes or not the action of the correction cam 1a and a drive star 11 of this annual cam 18. This simplicity guarantees the reliability of the mechanism, all the organs being made up by toothed organs with the exception of the correction scale 8 necessary to take the additional step to the end of the months of less than 31 days and which makes it possible to return this instant fix.

    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 traínant. 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 as well in plan that in height. Although we have described an annual calendar associated with an instantaneous jump mechanism, this invention is obviously applicable to other date mechanisms semi-instantaneous jump or trailing change of date. Likewise, as we have seen, this invention also applies to a calendar indicating the date, the day and month, like a single calendar or a calendar indicating the date and the day.
