Abstract

The time piece has a timepiece movement and a Chinese calendar display including lunar date and month indicators (12, 14). A date runner (50) has a date wheel (51) moved forward one step at each day and a drive finger (52) to move a month star wheel (60) forward to one step at the end of each revolution of the runner. A lunar month length selector (27) defines two stop positions for a month of thirty days and twenty-nine days, respectively. A bissextile month selector has a finger to move back the star wheel to one step when the month selector passes from normal to a bissextile position.

Description

Arrière-plan de l'inventionBackground of the invention

La présente invention a pour objet une pièce d'horlogerie pourvue d'un mécanisme de calendrier actionné chaque jour par le mouvement d'horlogerie et capable d'afficher la date selon le calendrier traditionnel chinois.The present invention relates to a timepiece provided with a calendar mechanism operated daily by the watch movement and capable of displaying the date according to the traditional Chinese calendar.

Le calendrier chinois est encore utilisé de nos jours pour fixer la date de certaines fêtes et pour l'astrologie chinoise. Il est du type luni-solaire, en ce sens qu'il se base sur des mois lunaires qui commencent chacun le jour de la nouvelle lune, tandis que les années chinoises ont une durée variable afin de se rapprocher des années tropiques dans la mesure du possible.The Chinese calendar is still used today to set the date of certain festivals and for Chinese astrology. It is of the luni-solar type, in that it is based on lunar months that start each day of the new moon, while the Chinese years have a variable duration in order to get closer to the tropical years in the measure of possible.

L'année chinoise commence à la deuxième nouvelle lune qui suit le solstice d'hiver, sauf de rares exceptions. Etant donné que la durée des lunaisons n'est pas constante et que sa valeur moyenne (29,53088 jours) n'est pas égale à un nombre entier de jours, le calendrier chinois comporte des mois longs de 30 jours et des mois courts de 29 jours. Aucun cycle des mois longs et courts n'a pu être défini.The Chinese year begins with the second new moon following the winter solstice, with rare exceptions. Since the duration of lunations is not constant and its average value (29.53088 days) is not equal to a whole number of days, the Chinese calendar has months of 30 days and short months of 29 days. No cycles of long and short months could be defined.

En outre, pour que la durée moyenne des années chinoises corresponde à celle d'une année tropique, il est prévu des années normales à douze mois et des années bissextiles à treize mois, dans lesquelles le mois supplémentaire, dit mois bissextile, est inséré dans une position ― c'est-à-dire un rang - qui varie d'une année bissextile à une autre en fonction des données astronomiques. Ce mois reprend le numéro du mois précédent, de sorte que le dernier mois d'une année porte toujours le numéro 12. Un fait gênant pour un affichage mécanique de calendrier chinois est qu'aucun cycle de la position du mois bissextile dans l'année n'a pu être défini.In addition, for the average duration of the Chinese years to correspond to that of a tropical year, normal years are expected at twelve months and leap years at thirteen months, in which the additional month, called the leap month, is inserted in a position - that is, a rank - that varies from leap year to another depending on the astronomical data. This month picks up the number from the previous month, so the last month of a year still carries the number 12. An annoying fact for a Chinese calendar mechanical display is that no cycle of the leap month position in the year could not be defined.

Les années normales peuvent comporter 353, 354 ou 355 jours, tandis que les années bissextiles peuvent comporter 383, 384 ou 385 jours. Les années normales et bissextiles se succèdent pratiquement selon un cycle de dix-neuf ans, qui correspond au cycle de Méton du calendrier grec et comporte à peu de chose près des nombres entiers de jours, de lunaisons et d'années chinoises, avec douze années normales et sept années bissextiles. Toutefois ce cycle n'est pas exact à long terme.Normal years can be 353, 354, or 355 days, while leap years can be 383, 384, or 385 days. The normal and leap years follow each other in almost a nineteen-year cycle, which corresponds to the cycle of the Meton of the Greek calendar, and roughly comprises whole numbers of days, lunates, and Chinese years, with twelve years normal and seven leap years. However, this cycle is not accurate in the long run.

REINGOLD, Calendrical Calculations, Cambridge University Press, 1997 , ainsi qu'aux publications de Helmer ASLAKSEN : The Mathematics of the Chinese Calendar, 13 May 2004, et LeapMonths.nb, Mathematica package, 1999, disponibles sur le site www.math.nus.edu.sg/aslaksen/.

A cause des particularités résumées ci-dessus du calendrier chinois, on ne peut actuellement pas réaliser un mécanisme d'affichage des dates de ce calendrier qui puisse être entraîné par un mouvement d'horlogerie et fonctionner à long terme avec exactitude et sans intervention manuelle, comme le font les mécanismes connus de calendrier perpétuel julien ou grégorien, par exemple selon le brevet CH 660 440 , ou comme le prévoit le brevet EP 606 576 pour un affichage de calendrier musulman.Because of the peculiarities summarized above of the Chinese calendar, one can not at present realize a mechanism of display of the dates of this calendar which can be driven by a clockwork movement and to work in the long term with exactitude and without manual intervention, as do known mechanisms of Julian or Gregorian perpetual calendar, for example according to the patent CH 660 440 , or as provided in the patent EP 606,576 for a Muslim calendar display.

Résumé de l'inventionSummary of the invention

La présente invention vise à créer un mécanisme de calendrier entraîné quotidiennement par le mouvement d'une pièce d'horlogerie et capable d'afficher des dates du calendrier traditionnel chinois au moins sous la forme du quantième lunaire et du mois lunaire, en tenant compte des mois bissextiles, et qui soit réalisable en pratique et de préférence sous une forme assez réduite pour être incorporé à une montre. Une idée de base de l'invention consiste à réaliser un mécanisme non perpétuel, dans lequel le porteur de la montre peut introduire manuellement des informations nécessaires pour obtenir un affichage correct des dates, et cela d'une manière peu contraignante.The present invention aims to create a calendar mechanism driven daily by the movement of a timepiece and capable of displaying dates of the traditional Chinese calendar at least in the form of the lunar calendar and the lunar month, taking into account the leap month, and that is practically feasible and preferably in a form reduced enough to be incorporated in a watch. A basic idea of the invention consists in producing a non-perpetual mechanism, in which the wearer of the watch can manually introduce information necessary to obtain a correct display of the dates, and this in a non-restrictive manner.

  • un sélecteur de durée de mois lunaire, ayant au moins deux positions et des surfaces de came servant d'appui pour la bascule de commande, pour définir alternativement deux positions différentes d'arrêt de ladite bascule correspondant respectivement à un mois de trente jours et à un mois de vingt-neuf jours, la bascule de commande étant munie d'un cliquet coopérant avec le mobile de quantième pour l'avancer d'un pas supplémentaire par le mouvement de ladite bascule à la fin d'un mois de vingt-neuf jours ;
  • un premier organe manuel de commande agencé pour changer la position du sélecteur de durée de mois lunaire ;
  • un sélecteur de mois bissextile, ayant une position normale et une position bissextile et pourvu d'un doigt agencé pour faire reculer d'un pas l'étoile des mois quand ledit sélecteur passe de la position normale à la position bissextile ;
  • et un second organe manuel de commande agencé pour faire passer le sélecteur de mois bissextile de la position normale à la position bissextile.
For this purpose, there is provided a timepiece comprising a clockwork movement and a Chinese calendar display device, characterized in that the Chinese calendar display device comprises:
  • a calendar mechanism comprising a control rocker actuated daily by a driving wheel of the watch movement;
  • an indicator of lunar month associated with a star of twelve-toothed months;
  • a lunar calendar indicator associated with a date mobile comprising a thirty-tooth calendar wheel which is advanced by one step each day by a nose of the control lever, the date mobile further comprising a driver finger arranged to move forward the star of the months of a step at the end of each turn of the mobile of date;
  • a lunar month duration selector, having at least two positions and cam surfaces serving as a support for the control rocker, for alternately defining two different stopping positions of said latch respectively corresponding to a month of thirty days and to a month of twenty-nine days, the control rocker being provided with a pawl cooperating with the date mobile to advance a step further by the movement of said latch at the end of a month of twenty-nine days ;
  • a first manual control member arranged to change the position of the lunar month duration selector;
  • a leap month selector, having a normal position and a leap position and provided with a finger arranged to step back the star of the months when said selector switches from the normal position to the leap position;
  • and a second manual control member arranged to move the leap month selector from the normal position to the leap position.

Le sélecteur de durée de mois lunaire, qui n'a que deux positions différentes quant à leur effet, peut avantageusement être couplé à un indicateur de durée de mois, visible sur le cadran. De même, le sélecteur de mois bissextile n'a que deux positions différentes quant à leur effet et peut avantageusement être couplé à un indicateur de genre de mois, visible sur le cadran.The lunar month duration selector, which has only two different positions as to their effect, can advantageously be coupled to a month duration indicator, visible on the dial. Similarly, the leap month selector has only two different positions as to their effect and may advantageously be coupled to a month-type indicator, visible on the dial.

Ainsi, si l'indicateur de durée de mois indique la durée correcte du mois en cours, l'utilisateur de la pièce d'horlogerie n'a rien à faire pour que l'affichage du quantième et du mois lunaire change correctement à la fin du dernier jour du mois. Si l'utilisateur coristate que l'indication de durée du mois en cours n'est pas correcte, il la corrige par une action sur le premier organe manuel de commande pour mettre le sélecteur de durée de mois dans l'autre position à n'importe quel moment, pourvu que ce soit avant l'action du doigt entraîneur du mobile de quantième à la fin de ce mois.Thus, if the month duration indicator indicates the correct duration of the current month, the user of the timepiece has nothing to do so that the display of the calendar and the lunar month changes correctly at the end. the last day of the month. If the user coristates that the indication of duration of the current month is not correct, it corrects it by an action on the first manual control organ to put the selector of duration of month in the other position to n ' any time, provided that it is before the action of the trainer finger of the mobile of date at the end of this month.

Quand un mois bissextile commence, le numéro de mois affiché par l'indicateur de mois lunaire augmente d'une unité comme dans un mois normal et il devra donc être diminué d'une unité pour reprendre le numéro du mois précédent. L'utilisateur le fait lui-même en actionnant le second organe manuel de commande, ce qui change la position du sélecteur de mois bissextile et fait ainsi reculer l'étoile des mois et l'indicateur associé. On verra plus loin que ce sélecteur peut revenir automatiquement à sa position normale à la fin du mois bissextile, si bien que l'utilisateur ne doit actionner le second organe de commande qu'une seule fois pour chaque mois bissextile, donc seulement sept fois au cours d'un cycle de dix-neuf années chinoises.When a leap month starts, the month number displayed by the lunar month indicator increases by one unit as in a normal month, so it will need to be decreased by one to take the number from the previous month. The user does this himself by operating the second manual control device, which changes the position of the leap month selector and thus moves back the month star and the associated indicator. It will be seen later that this selector can automatically return to its normal position at the end of the leap month, so that the user must actuate the second control member only once for each leap month, so only seven times at the end of the leap month. during a cycle of nineteen Chinese years.

Description détaillée d'un mode de réalisationDetailed description of an embodiment

La montre représentée sans son habillement dans la figure 1 comporte de manière classique une boîte contenant un mouvement 3 d'horlogerie mécanique ou électromécanique qui actionne un affichage analogique de l'heure. Celui-ci comprend ici une aiguille des minutes 4 et une aiguille des heures 5 qui tournent devant un cadran 6 muni d'un tour d'heures 7. La montre peut aussi comporter un affichage de calendrier usuel, par exemple de type julien, qui est entraîné une fois par jour par le mouvement d'horlogerie et n'est pas représenté dans le dessin. Une couronne 8 liée à une tige de commande classique 9 permet le réglage manuel de l'heure et de la date, ainsi que lé remontage si le mouvement est mécanique. D'autres moyens de commande manuels sont formés par des poussoirs 10 et 11 dont la fonction apparaîtra plus loin.The watch represented without his clothing in the figure 1 conventionally comprises a box containing a mechanical or electromechanical watch movement 3 which actuates an analog time display. This includes here a minute hand 4 and a hand of the hours 5 which turn in front of a dial 6 provided with a clock tower 7. The watch may also include a usual calendar display, for example of Julian type, which is driven once a day by the watch movement and is not shown in the drawing. A ring 8 linked to a conventional control rod 9 allows the manual adjustment of the time and date, and the reassembly if the movement is mechanical. Other manual control means are formed by pushers 10 and 11 whose function will appear below.

La montre comporte en outre un affichage de calendrier chinois comprenant quatre indicateurs associés au cadran 6, à savoir : un indicateur de quantième lunaire 12 formé par un disque dont une portion est visible dans un guichet 13 du cadran ; un indicateur de mois lunaire 14 formé par un disque dont une portion est visible dans un autre guichet 15 du cadran ; un indicateur de longueur du mois 16 formé par une aiguille ayant deux positions en face de deux repères C et L sur le cadran ; et enfin un indicateur de genre du mois 18 formé par une aiguille ayant deux positions en face de deux repères N et B sur le cadran. Les repères C et L représentent respectivement un mois lunaire court de vingt-neuf jours et un mois lunaire long de trente jours. Les repères B et N représentent respectivement un mois lunaire bissextile et un mois lunaire non bissextile, qu'on appellera mois normal. Un mois normal peut être court ou long, de même qu'un mois bissextile. Les indicateurs 12, 14, 16 et 18 sont commandés par un mécanisme de calendrier chinois illustré par les figures 2 à 13.The watch further comprises a Chinese calendar display comprising four indicators associated with the dial 6, namely: a lunar calendar indicator 12 formed by a disk, a portion of which is visible in a window 13 of the dial; an indicator of lunar month 14 formed by a disk, a portion of which is visible in another window 15 of the dial; a length indicator of the month 16 formed by a needle having two positions opposite two C and L marks on the dial; and finally a gender indicator of the month 18 formed by a needle having two positions in front of two N and B marks on the dial. C and L represent respectively a short lunar month of twenty-nine days and a lunar month thirty days long. The B and N markings respectively represent a lunar lunar month and a month non-leap lunar, which will be called normal month. A normal month can be short or long, as well as a leap month. Indicators 12, 14, 16 and 18 are controlled by a Chinese calendar mechanism illustrated by the Figures 2 to 13 .

Le mécanisme de calendrier 20 représenté partiellement dans les figures 2 à 5 est actionné une fois par jour par une roue entraîneuse 21 qui est entraînée par la roue des heures du mouvement d'horlogerie pour faire un tour en vingt-quatre heures. La roue 21 porte une goupille d'entraînement 22 qui agit sur une bascule de commande 23 pivotant autour du point 24, la goupille 22 étant montée de manière élastique sur la roue 21 pour ne pas interférer avec des mouvements de correction du mécanisme 20. Un ressort 25 tend à appuyer une saillie 26a d'un bras 26 de la bascule 23 contre un sélecteur 27 formé ici par une roue à colonnes, dont les six colonnes 28 sont semblables et séparées par des intervalles égaux 32. Le pourtour de la roue à colonnes forme une sorte de came qui détermine alternativement deux positions d'arrêt différentes de la bascule 23. Le sélecteur 27 comporte en outre une denture extérieure 33 dont le nombre de dents est le double du nombre de colonnes, cette denture étant maintenue en position par un ressort-sautoir 34. La denture 33 permet en outre de faire avancer manuellement pas à pas le sélecteur 27 dans le sens anti-horaire au moyen d'une bascule de sélection 35 pivotée en 36, pourvue d'un ressort de rappel et d'une dent 37 au bout d'un bras flexible. Cette bascule est actionnée par le poussoir 10 représenté dans la figure 1.The calendar mechanism 20 partially represented in the Figures 2 to 5 is operated once a day by a driving wheel 21 which is driven by the hour wheel of the watch movement to make a turn in twenty-four hours. The wheel 21 carries a driving pin 22 which acts on a control rocker 23 pivoting about the point 24, the pin 22 being resiliently mounted on the wheel 21 so as not to interfere with the correction movements of the mechanism 20. spring 25 tends to support a projection 26a of an arm 26 of the rocker 23 against a selector 27 formed here by a column wheel, the six columns 28 are similar and separated by equal intervals 32. The periphery of the wheel to The columns form a kind of cam that alternately determines two different stop positions of the rocker 23. The selector 27 further comprises an external toothing 33 whose number of teeth is twice the number of columns, this toothing being held in position by A spring 34. The toothing 33 further makes it possible to manually advance the selector 27 in the anti-clockwise direction by means of a selector lever 35 rotated at 36, provided with a return spring and a tooth 37 at the end of a flexible arm. This flip-flop is actuated by the pusher 10 represented in FIG. figure 1 .

Un second bras 38 de la bascule 23 est pourvu d'un bec 40 et d'un cliquet 41, lequel est pivoté en 42 sur la bascule et poussé dans le sens horaire par un ressort 43 s'appuyant contre une goupille 44 du cliquet.A second arm 38 of the rocker 23 is provided with a spout 40 and a pawl 41, which is pivoted at 42 on the rocker and pushed in the clockwise direction by a spring 43 resting against a pin 44 of the pawl.

Le disque indicateur de quantième 12 (qui n'est représenté que très partiellement dans les figures 2 à 5 pour la clarté du dessin) fait partie d'un mobile de quantième 50 comprenant en outre une roue de quantième 51 à trente dents, un doigt entraîneur des mois 52 et une came 53 en forme de spirale, présentant un décrochement 54. Le cliquet 41 de la bascule 23 s'appuie en glissant sur cette came et peut buter contre le décrochement 54. Un sautoir 56 sollicité par un ressort 57 s'appuie sur les dents de la roue 51 pour la maintenir dans trente positions successives.The date indicator disc 12 (which is only partially represented in the Figures 2 to 5 for the clarity of the drawing) is part of a date mobile 50 further comprising a date wheel 51 with thirty teeth, a driving finger months 52 and a cam 53 in the form of a spiral, having a recess 54. The pawl 41 of the rocker 23 rests by sliding on this cam and can abut against the recess 54. A jumper 56 biased by a spring 57 rests on the teeth of the wheel 51 to maintain it in thirty successive positions.

Comme le disque 12, le disque indicateur de mois 14 n'est représenté que très partiellement dans les figures 2 à 5. Il est solidaire d'une roue des mois 60 à douze dents, maintenue en position par un sautoir 61 sollicité par un ressort 62. Le doigt 52 du mobile de quantième 50 fait avancer d'un pas la roue 60 et le disque 14 à la fin de chaque tour du mobile 50.Like the disc 12, the month indicator disc 14 is only partially represented in the Figures 2 to 5 . It is secured to a wheel 60 to twelve teeth, maintained in position by a jumper 61 biased by a spring 62. The finger 52 of the date mobile 50 advances a step 60 wheel and the disc 14 at the end of each turn of the mobile 50.

Lorsque le mois lunaire courant est un mois long, c'est-à-dire comportant trente jours, le sélecteur 27 doit se trouver dans la position représentée aux figures 2 et 3, de sorte que le bras 26 de la bascule 23 s'appuie contre l'une des colonnes 28 et que l'autre extrémité 64 de la bascule 23 se trouve dans une position légèrement décalée vers la droite par rapport à l'axe de la roue entraîneuse 21. Chaque soir vers minuit, comme on le voit dans la figure 3, la goupille 22 pousse cette extrémité pour faire pivoter la bascule 23 dans le sens de la flèche B, de sorte que le bec 40 de la bascule entre en contact avec les dents de la roue de quantième 51 et fait ainsi avancer d'un pas le module de quantième 50, incrémentant d'une unité le quantième affiché dans le guichet 13. Au soir du trentième jour du mois, l'indication de quantième passe ainsi à 30 à 01 comme le montre la figure 3. En même temps, le doigt 52 du mobile 50 fait avancer d'un pas la roue des mois 60 et le disque 14, incrémentant d'une unité le numéro du mois dans le guichet 15. En même temps aussi, le cliquet 41 de la bascule 23 tombe dans le décrochement 54 de la came 53 sans produire d'effet particulier.When the current lunar month is a long month, that is to say, having thirty days, the selector 27 must be in the position represented at figures 2 and 3 so that the arm 26 of the rocker 23 rests against one of the columns 28 and the other end 64 of the rocker 23 is in a position slightly shifted to the right with respect to the axis of the coaching wheel 21. Every evening around midnight, as seen in the figure 3 the pin 22 pushes this end to pivot the rocker 23 in the direction of the arrow B, so that the tip 40 of the rocker comes into contact with the teeth of the date wheel 51 and thus advances a step the date module 50, incrementing by one unit the date displayed in the window 13. At the evening of the thirtieth day of the month, the date indication thus passes to 30 to 01 as shown in FIG. figure 3 . At the same time, the finger 52 of the mobile 50 advances by one step the wheel of the months 60 and the disk 14, incrementing by one unit the number of the month in the window 15. At the same time also, the pawl 41 of the flip-flop 23 falls into the recess 54 of the cam 53 without producing any particular effect.

Les figures 4 et 5 représentent le cas où le mois lunaire courant est un mois court, c'est à dire comportant seulement vingt-neuf jours. La position du sélecteur 27 est alors pivotée d'un douzième de tour par rapport à celle des figures 2 et 3, de sorte que la saillie 26a du bras 26 de la bascule 23 pénètre dans l'un des intervalles 32 en s'appuyant contre les deux colonnes 28 voisines et que l'autre extrémité 64 de la bascule se trouve plus à gauche que dans le cas précédent. Le passage d'une position à l'autre du sélecteur 27 est commandé manuellement, au moyen du poussoir 10 symbolisé ici par une flèche et produisant un pivotement en va-et-vient de la bascule de sélection 35 pour faire avancer d'un pas la roue dentée 33 au moyen de la dent 37.The figures 4 and 5 represent the case where the current lunar month is a short month, ie comprising only twenty-nine days. The position of the selector 27 is then rotated one twelfth of a turn relative to that of the figures 2 and 3 , so that the projection 26a of the arm 26 of the rocker 23 enters one of the intervals 32 bearing against the two adjacent columns 28 and that the other end 64 of the rocker is more left than in the previous case. The passage from one position to another of the selector 27 is controlled manually, by means of the pusher 10 symbolized here by an arrow and producing a pivoting back and forth of the selection rocker 35 to advance a step the toothed wheel 33 by means of the tooth 37.

Jusqu'au soir du vingt-huitième jour, l'incrémentation quotidienne du quantième dans le guichet 13 par rotation d'un pas du mobile de quantième 50 s'effectue comme dans l'exemple précédent, sauf que la course initiale à vide de la bascule 23 et de son bec 40 est plus grande. Le cliquet 41 glisse sur la came 53 sans produire d'effet.Until the evening of the twenty-eighth day, the daily incrementation of the date in the aperture 13 by rotation of a step of the date mobile 50 is carried out as in the preceding example, except that the initial empty stroke of the flip-flop 23 and its spout 40 is larger. The pawl 41 slides on the cam 53 without producing any effect.

Le vingt-neuvième jour, le cliquet 41 de la bascule se trouve dans le décrochement 54 de la came 53, comme le montre la figure 4. Le soir, la goupille 22 de la roue d'entraînement 21 produit le mouvement indiqué par des flèches dans la figure 5. Le pivotement de la bascule a d'abord pour effet que le cliquet 41 fait avancer d'un pas le mobile 50, de sorte que le disque de quantième 12 va afficher la valeur 30 dans le guichet 13. Quelques minutes plus tard, le bec 40 de la bascule entre en contact avec la roue 51 et fait avancer d'un autre pas le mobile 50, amenant l'indication du quantième 01 dans le guichet 13 et faisant simultanément avancer d'un pas, par le doigt entraîneur 52, la roue des mois 60 et le disque 14 pour incrémenter d'une unité le numéro du mois dans le guichet 15.On the twenty-ninth day, the latch 41 of the latch is in the recess 54 of the cam 53, as shown in FIG. figure 4 . In the evening, the pin 22 of the drive wheel 21 produces the movement indicated by arrows in the figure 5 . The pivoting of the rocker first has the effect that the pawl 41 advances the mobile 50 by one step, so that the date disc 12 will display the value 30 in the aperture 13. A few minutes later, the beak 40 of the rocker contacts the wheel 51 and advances another step the mobile 50, bringing the indication of the date 01 in the aperture 13 and simultaneously advancing, by the driving finger 52, the wheel of the months 60 and the disk 14 to increment by one unit the number of the month in the window 15.

Les figures 6 et 7 représentent une partie du mécanisme 20 qui n'est pas représentée dans les figures 2 à 5 pour des raisons de clarté. Il s'agit de la partie formant l'indicateur de longueur des mois, en particulier avec l'aiguille 16 représentée dans la figure 1. Cette aiguille est solidaire d'une bascule 66 pivotée en 67 et sollicitée par un ressort 68 de façon que son bec 69 soit maintenu appuyé contre les colonnes 28 du sélecteur 27. Lorsque la position du sélecteur correspond à un mois long, comme le montre la figure 6, le bec 69 et la bascule 66 pénètrent dans l'un des intervalles 32 en s'appuyant contre deux colonnes 28, si bien que l'aiguille 16 pointe sur le symbole L représentant un mois long. Par contre, lorsque l'utilisateur fait tourner manuellement le sélecteur 27 d'un douzième de tour dans le sens indiqué par la flèche dans la figure 7, le bec 69 est repoussé par la colonne 28 voisine et la bascule 66 pivote de sorte que l'aiguille 16 pointe sur le symbole C représentant un mois court. La prochaine avance d'un pas du sélecteur 27 ramènera le mécanisme dans la position de la figure 6.The Figures 6 and 7 represent a part of the mechanism 20 that is not represented in the Figures 2 to 5 for the sake of clarity. This is the part forming the month length indicator, in particular with the needle 16 shown in FIG. figure 1 . This needle is integral with a rocker 66 pivoted at 67 and biased by a spring 68 so that its spout 69 is held pressed against the columns 28 of the selector 27. When the position of the selector corresponds to a long month, as shown in FIG. figure 6 , the spout 69 and the rocker 66 penetrate one of the intervals 32 against two columns 28, so that the needle 16 points to the symbol L representing a long month. On the other hand, when the user manually turns the selector 27 one twelfth of a turn in the direction indicated by the arrow in the figure 7 , the spout 69 is pushed by the adjacent column 28 and the rocker 66 pivots so that the needle 16 points to the symbol C representing a short month. The next step advance of the selector 27 will return the mechanism to the position of the figure 6 .

A titre de variante remplaçant l'indication par l'aiguille 16, les figures 6 et 7 montrent qu'on peut aussi appliquer sur la bascule 66 les symboles respectifs L et C des mois longs et courts de façon qu'ils apparaissent à tour de rôle dans un guichet 71 du cadran.As a variant replacing the indication by the needle 16, the Figures 6 and 7 show that one can also apply on the latch 66 the respective symbols L and C of long and short months so that they appear in turn in a window 71 of the dial.

Les figures 8 à 11 représentent une partie du mécanisme de calendrier 20 décrit plus haut, où l'on a ajouté un sélecteur de mois bissextile 75, formé par un levier pivotant qui est couplé à l'aiguille 18 représentée dans la figure 1. Le levier 75 pivote en 76 et présente deux encoches 77 permettant de l'arrêter dans deux positions au moyen d'un sautoir 78 épaulé par un ressort 79. Ce levier est muni d'un doigt 80 qui coopère avec la denture de la roue des mois 60. Le doigt 80 est dégagé de cette denture tant que le sélecteur 75 occupe sa position normale représentée dans la figure 8, où l'aiguille 18 pointe sur le symbole N indiquant que le mois courant est un mois normal. Selon cette figure, il s'agit du deuxième mois de l'année, d'où l'indication 02 donnée par le disque des mois 14 dans le guichet 15.The Figures 8 to 11 represent a part of the timing mechanism 20 described above, where a leap month selector 75, formed by a pivoting lever which is coupled to the needle 18 shown in FIG. figure 1 . The lever 75 pivots at 76 and has two notches 77 to stop in two positions by means of a jumper 78 shouldered by a spring 79. This lever is provided with a finger 80 which cooperates with the toothing of the wheel of 60. The finger 80 is disengaged from this toothing as long as the selector 75 occupies its normal position represented in FIG. figure 8 , where the needle 18 points to the symbol N indicating that the current month is a normal month. According to this figure, it is the second month of the year, hence the indication 02 given by the month 14 disk in the window 15.

Cependant, on prend ici comme hypothèse que ce mois est un mois bissextile, un fait dont le porteur de la montre est informé par un calendrier imprimé, par la presse ou par tout autre moyen. L'utilisateur va alors corriger l'indication du calendrier de la manière suivante. Dans la figure 9, le poussoir manuel 11 représenté par une flèche agit sur le levier 75 pour le mettre dans sa seconde position, de sorte que l'aiguille 18 passe du symbole N au symbole B représentant un mois bissextile et que le doigt 80 du levier fait tourner la roue des mois 60 d'un pas dans le sens horaire, reculant ainsi d'une unité le numéro du mois affiché dans le guichet 15. Le mois courant bissextile reprend ainsi le numéro du mois précédent. On notera que cette opération n'a aucun effet sur le mobile de quantième 50 et l'affichage du quantième dans le guichet 13.However, it is assumed here that this month is a leap month, a fact of which the wearer of the watch is informed by a printed calendar, by the press or by any other means. The user will then correct the calendar indication as follows. In the figure 9 , the manual pushbutton 11 represented by an arrow acts on the lever 75 to put it in its second position, so that the needle 18 passes from the symbol N to the symbol B representing a leap month and that the finger 80 of the lever rotates the wheel of the month 60 by one step clockwise, thus reducing by one unit the number of the month displayed in the window 15. The leap month thus repeating the number of the previous month. Note that this operation has no effect on the calendar mobile 50 and the date display in the window 13.

Les flèches de la figure 10 montrent les mouvements qui se passent à la fin du mois bissextile, quand le doigt entraîneur des mois 52 va faire avancer la roue des mois 60 et le disque 14 d'un pas dans le sens anti-horaire. Cette rotation va ramener le sélecteur de mois bissextile 75 à sa position normale représentée dans la figure 11, en même temps qu'elle fera apparaître le numéro 02 du nouveau mois qui commence. Grâce à la position normale du sélecteur 75, toutes les fins de mois suivantes feront incrémenter normalement l'indicateur de mois, tant qu'on n'aura pas actionné de nouveau le poussoir 11.The arrows of the figure 10 show the movements that occur at the end of the leap month, when the month 52 trainer finger will advance the 60-month wheel and the 14-wheel counter-clockwise. This rotation will return the leap month selector 75 to its normal position represented in FIG. figure 11 , at the same time it will show the number 02 of the new month that begins. With the normal position of the selector 75, all the following month ends will normally increment the month indicator, as long as the button 11 has not been pressed again.

Au vu de la description qui précède, on comprend que la montre selon l'invention indique correctement le quantième et le numéro du mois dans le calendrier chinois dans la mesure où les actions suivantes sont faites :

  1. 1. Au cours de chaque mois, l'utilisateur doit vérifier si l'indication de mois long ou court par l'aiguille de l'indicateur 16 est correcte. Si elle est incorrecte, il doit la changer par une pression sur le poussoir 10.
  2. 2. Au début d'un mois bissextile, l'utilisateur doit introduire cette information dans le mécanisme de calendrier par une pression sur le poussoir 11, de sorte que l'indicateur de mois bissextile 18 passera de la position N à la position B, puis reviendra automatiquement à la position N à la fin du mois.
In view of the foregoing description, it is understood that the watch according to the invention correctly indicates the date and the number of the month in the Chinese calendar insofar as the following actions are made:
  1. 1. During each month, the user must check whether the indication of long or short month by the pointer of indicator 16 is correct. If it is incorrect, it must be changed by pressing the pushbutton 10.
  2. 2. At the beginning of a leap month, the user must enter this information into the calendar mechanism by pressing the push-button 11, so that the leap month indicator 18 will change from position N to position B, then automatically return to the N position at the end of the month.

Grâce à ces opérations manuelles simples, il est devenu possible de réaliser un mécanisme d'affichage de calendrier chinois qui n'est pas très compliqué, de sorte qu'on peut l'incorporer dans une montre-bracelet, et qui donne des indications justes tout au long de l'année malgré le caractère non cyclique du calendrier chinois.Thanks to these simple manual operations, it has become possible to make a Chinese calendar display mechanism which is not very complicated, so that it can be incorporated into a wristwatch, and which gives correct indications. throughout the year despite the non-cyclical nature of the Chinese calendar.

Les figures 12 et 13 représentent une variante d'une partie du mécanisme de calendrier 20 décrit plus haut, à savoir un sélecteur de durée des mois qui remplace le sélecteur rotatif 27 et la bascule 66 représentés dans les figures 2 à 7. Dans ce cas, l'aiguille de l'indicateur de longueur de mois 16 est solidaire d'un sélecteur 82 pivotant en va-et-vient, ayant deux surfaces de came 83 et 84 contre lesquelles peut s'appuyer la bascule 23 représentée aux figures 2 à 5. La surface de came 83 a un plus grand rayon que la surface de came 84 par rapport à l'axe de pivotement 85, pour maintenir la bascule 23 dans une position correspondant à un mois long comme le faisait une colonne 28 de la roue à colonnes dans l'exemple précédent. La surface de came 84 constitue le point d'appui de la bascule dans le cas d'un mois court. Ces deux positions du sélecteur 82 sont stabilisées par un ressort-sautoir 86 s'engageant alternativement dans deux encoches 87 du sélecteur.The Figures 12 and 13 represent a variant of a part of the calendar mechanism 20 described above, namely a selector of duration of months which replaces the rotary selector 27 and the latch 66 represented in the Figures 2 to 7 . In this case, the hand of the indicator of length of month 16 is integral with a selector 82 pivoting back and forth, having two cam surfaces 83 and 84 against which can press the rocker 23 shown in FIGS. Figures 2 to 5 . The cam surface 83 has a greater radius than the cam surface 84 relative to the pivot axis 85, to keep the latch 23 in a position corresponding to a long month as did a column 28 of the column wheel in the previous example. The cam surface 84 constitutes the fulcrum of the rocker in the case of a short month. These two selector positions 82 are stabilized by a jumper spring 86 engaging alternately in two notches 87 of the selector.

La commutation d'une position à l'autre du sélecteur 82 au moyen du poussoir 10 mentionné dans l'exemple précédent s'effectue au moyen d'une transmission à navette de type connu, comprenant une navette 90 et un coulisseau 91. Une goupille 92 de la navette 90 est guidée linéairement dans une rainure 93 de la platine du mouvement et elle est repoussée par un ressort 94 pour qu'une extrémité 95 de la navette s'appuie dans un creux de l'extrémité correspondante du coulisseau 91. Ce dernier est également guidé linéairement sur deux goupilles fixes 96. L'extrémité avant de la navette 90 a une forme rectangulaire et s'appuie alternativement sur l'un ou l'autre de deux angles saillants 97 et 98 disposés de part et autre d'un creux 99 du sélecteur 82. Au repos, le ressort 94 repousse la navette 90 à distance du sélecteur 82. A chaque pression sur le poussoir 11, la navette 90 pousse celui des angles 97 et 98 qui se trouve devant elle, ce qui fait pivoter le sélecteur 82 et l'aiguille 16 vers l'autre position et amène l'autre angle devant la navette. La prochaine pression sur le poussoir 11 produit ainsi l'effet inverse, c'est-à-dire que le sélecteur 82 a un mouvement de va-et-vient.Switching from one position to another of the selector 82 by means of the pusher 10 mentioned in the preceding example is effected by means of a known type of shuttle transmission, comprising a shuttle 90 and a slider 91. A pin 92 of the shuttle 90 is linearly guided in a groove 93 of the platen of the movement and is pushed by a spring 94 so that an end 95 of the shuttle rests in a hollow of the corresponding end of the slide 91. The last is also guided linearly on two fixed pins 96. The front end of the shuttle 90 has a rectangular shape and is supported alternately on one or the other of two projecting angles 97 and 98 arranged on either side of a depression 99 of the selector 82. At rest, the spring 94 pushes the shuttle 90 away from the selector 82. With each pressure on the pusher 11, the shuttle 90 pushes that of the angles 97 and 98 which is in front of it, which makes rotate the selector 82 e t the needle 16 to the other position and brings the other angle in front of the shuttle. The next press on the pusher 11 thus produces the opposite effect, that is to say that the selector 82 is reciprocated.

Ainsi, le mécanisme des figures 12 et 13 remplace à la fois le sélecteur 27 représenté dans les figures 2 à 5 et l'indicateur à bascule 66 représenté dans les figures 6 et 7.Thus, the mechanism of Figures 12 and 13 replaces both the selector 27 shown in the Figures 2 to 5 and the rocker indicator 66 shown in Figures 6 and 7 .

La figure 14 représente un autre mode de réalisation d'une montre selon l'invention, ayant à la fois un affichage de calendrier chinois et un affichage de calendrier perpétuel julien sur le même cadran 101. La date dans le calendrier julien est indiquée par une aiguille de quantième 102, une aiguille de jour de la semaine 103, une aiguille du mois 104 et un indicateur d'année bissextile 105. La date dans le calendrier chinois est indiquée par une aiguille 112 indiquant le quantième sur une échelle circulaire des quantièmes lunaires 111 et par une aiguille 114 indiquant le mois lunaire sur une échelle circulaire 113. On notera que des symboles 115 des phases de la lune peuvent être associés à l'échelle 111 des quantièmes lunaires. Comme dans l'exemple précédent, l'affichage de calendrier chinois comporte en outre un indicateur 16 de longueur du mois et un indicateur 18 de genre du mois. Les indicateurs de calendrier chinois peuvent être actionnés par le même mécanisme que dans l'exemple précédent, dont les deux disques indicateurs 12 et 14 sont simplement remplacés par les aiguilles 112 et 114.The figure 14 represents another embodiment of a watch according to the invention, having both a Chinese calendar display and a Julian perpetual calendar display on the same dial 101. The date in the Julian calendar is indicated by a date hand. 102, a day hand of the week 103, a hand of the month 104 and a leap year indicator 105. The date in the Chinese calendar is indicated by a hand 112 indicating the date on a circular scale of the lunar calendar 111 and by a needle 114 indicating the lunar month on a circular scale 113. It will be noted that symbols 115 of the phases of the moon can be associated with the scale 111 of the lunar calendar. As in the previous example, the Chinese calendar display further includes a month length indicator 16 and a month gender indicator 18. The Chinese calendar indicators can be operated by the same mechanism as in the previous example, the two indicator discs 12 and 14 are simply replaced by the needles 112 and 114.
