Definitions
- 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.
- 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.
- 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.
- the subject of the present invention is a date mechanism of the aforementioned type, as defined by claim 1.
- this mechanism has 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.
- 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.
- 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.
- 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.
- 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.
- the mechanism that has just been described is that of a simple instantaneous calendar.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- the figures 4 and 5 show the passage from 30 September to 1 October.
- 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.
- 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.
- the finger 8b of the latch 8 falls into a recess 18 * of the annual cam 18.
- 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.
- 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.
- 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.
- 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.
- 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.
- the figure 6 illustrates an alternative that avoids the passage of 30 to 1 in two steps.
- 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.
- 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.
- 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.
- 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.
- 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.
- This mechanism occupies little space both in plan and height.
- this invention is obviously applicable to other semi-instantaneous date or trailing calendar change date mechanism mechanisms.
- 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.

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.

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
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.

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
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
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
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
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
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
Les
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
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
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
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
La
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
On peut encore constater sur la
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
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.

- Annual date mechanism for a clock movement comprising a date indicating runner (1) with thirty-one positions engaged once a day with a drive runner (5) in kinematic connection with the geartrain of said clock movement, an annual cam (18), the contour of which is shaped to distinguish the thirty-one-day months from the other months, means (1, 10-15) for driving this annual cam (18) by one revolution per year and a correction mechanism (1a, 8, 9) connected to said annual cam (18) to advance said indicating runner by one additional position at the end of each month of less than 31 days, this correction mechanism (1a, 8, 9) comprising a correction cam (1a) in kinematic connection with said date indicating runner (1), a correction rocker (8) engaged, on the one hand, with said correction cam (1a) and, on the other hand, with said annual cam (18), and a spring (9) for pressing said correction rocker (8) against said cams (1a, 18), characterized in that said correction cam (1a) comprises a portion (1a'), extending over an angle of approximately 30/31sts of the total travel thereof, for arming said spring (9), the end and the beginning of this cam being connected by a portion (1a*) that extends over approximately 1/31st of the total travel thereof and that is sized to cause said date runner (1) to move by one step between the "31" and the "1" under the pressure of said spring (9).
- Annual date mechanism as claimed in claim 1, in which said correction cam (1a) is of annular shape and is concentric and secured to said date runner (1) and bears a projection (10) intended to engage, on each revolution of said date runner (1), with a runner (11) for the driving of said annual cam (18) for driving said runner (11) by one step.
- Annual date mechanism as claimed in claim 1, in which said annual cam (18) is circular and divided into twelve equal sectors having two different respective diameters (18', 18*), a larger diameter for the 31-day months than for the other months, thus forming five recessed parts of smaller diameter (18*) corresponding to the months of under 31 days, which recessed parts can be entered by a finger (8b) secured to said correction rocker (8) under the pressure of said spring (9) when said correction cam (1a) frees said correction rocker (8) to the pressure of said spring (9), this annual cam (18) being concentric with a driving wheel (15), a spring (19) and relative displacement angular limiting means connecting said annual cam (18) to said driving wheel (15).
- Annual date mechanism as claimed in claim 1, in which said spring (9) has two arms, one pressing against said correction rocker (8) and the other against a pull-out time and date setting lever (21) of the winding and setting mechanism of said clock movement, so that when said pull-out setting lever (21) is moved into the time-setting or date-setting position, it simultaneously relaxes said spring (9).
- Annual date mechanism as claimed in claim 1, in which said driving runner (5) is connected to a set of teeth (1b) of said date indicating runner (1) by an instantaneous jump mechanism comprising a driving finger (3) secured to an instantaneous jump cam (4) concentric with said driving runner (5) and having, with respect to the latter, a degree of angular freedom equal to one step of said driving finger (3), so that immediately after said instantaneous jump, said driving finger (3) remains engaged with said set of teeth (1b) of the date indicating runner (1) and is held in this set of teeth by said driving runner for a sufficient length of time to prevent any additional movement of said date indicating runner (1).
- Annual date mechanism as claimed in claim 5, in which said date indicating runner (1) has an annular shape and is mounted to pivot via two rollers (20a, 20b) against which the edge of said date indicating runner (1) is held by the pressure exerted by a positioning jumper (2) of this indicating runner (1), the moment of the force (F1) with respect to one of said rollers (20a, 20b) exerted on this indicating runner (1) by said jumper (2) being appreciably lower than and developing a couple in the opposite direction to the moment of the force (F2) developed by said correction rocker (8) when it is in engagement with said portion (1*) sized to cause said date runner (1) to move by one step so as to move said date runner (1) with respect to said roller (20a) about which said couple exerted by said correction rocker (8) is exerted, said driving finger (3) being situated between this roller (20a) and the end of said rocker (8) in engagement with said portion (1a*) sized to cause said date runner (1) to move by one step so as to disengage the set of teeth (1b) of said date indicating runner (1) from said driving finger (3) when this runner is driven by said correction rocker(8)
