After the point 34B has passed through the roller 351 ,. the spring 352 suddenly pushes the roller 351 which falls into the next hollow 34A of the stop wheel 34, and this impulse controls the pivoting of the month display mobile 2 by one forty-eighth of a turn, to display the new month in window 1C. Thus the stop wheel 34 is constantly in contact with the pins 22 of the mobile month display 2.
- This stop wheel 34 rests on the pawl 35 all month, and this is only during the mobile monthly movement.
- the pawl 35 also rests for the whole month on a hollow 34A of the stop wheel 34, and is only moved along the latter during the monthly maneuver printed by the input mobile 31.

L'invention concerne le domaine des complications horlogères comportant un calendrier.The invention relates to the field of horological complications comprising a calendar.
Les mécanismes de calendriers font partie des complications horlogères classiques. Certains mécanismes complexes sont à même de gérer la durée des mois ou des années. Des afficheurs ou indicateurs d'année bissextile permettent à l'utilisateur de déterminer si l'année en cours est une année bissextile ou non, et, selon le niveau de complexité de la montre, peuvent gérer l'affichage du dernier jour du mois de février, et le passage correct au premier mars.Calendar mechanisms are one of the classic horological complications. Certain complex mechanisms are able to manage the duration of months or years. Leap year displays or indicators allow the user to determine whether the current year is a leap year or not, and, depending on the level of complexity of the watch, can manage the display of the last day of the month of February, and the correct transition to March 1.
Dans le cas des mécanismes de calendrier les plus simples, la simple connaissance du caractère bissextile ou non de l'année en cours permet à l'utilisateur d'effectuer correctement la correction d'affichage des derniers jours du mois en cours, en général par l'intermédiaire de la tige de commande. Les mécanismes diffèrent selon qu'il s'agit d'un quantième simple, d'un quantième annuel, ou d'un quantième perpétuel. Dans ces derniers cas, le mécanisme de gestion d'année bissextile nécessite des composants coûteux, par exemple une came en croix de Malte, et consomment un certain volume à l'intérieur de la boîte de montre, ou de la boîte de la pièce d'horlogerie si elle est statique comme une horloge.In the case of the simplest calendar mechanisms, the simple knowledge of the leap character or not of the current year allows the user to correctly correct the display of the last days of the current month, generally by through the control rod. The mechanisms differ depending on whether it is a simple calendar, an annual calendar, or a perpetual calendar. In the latter cases, the leap year management mechanism requires expensive components, for example a Maltese cross cam, and consumes a certain volume inside the watch case, or the part case. clockwork if it is static like a clock.

La correction est décrite ci-dessus pour le cas du calendrier grégorien. Un mécanisme de correction analogue, commandé par le mouvement ou par l'utilisateur, peut être effectué pour les autres types de calendrier, notamment de type lunaire, qui nécessitent des rattrapages à certaines périodes.The correction is described above for the case of the Gregorian calendar. A similar correction mechanism, controlled by the movement or by the user, can be performed for other types of calendar, in particular of the lunar type, which require adjustments at certain periods.
L'invention concerne encore une pièce d'horlogerie 1000 comportant au moins un mouvement d'horlogerie 100 agencé pour entraîner au moins tel un mécanisme d'affichage 10, ou/et pour entraîner au moins un tel mécanisme de calendrier 300.The invention also relates to a
Plus particulièrement, cette pièce d'horlogerie 1000 est une montre.More particularly, this
Naturellement, le principe de l'invention peut être étendu à d'autres types de pièces d'horlogerie à calendrier, notamment des montres astronomiques ou des horloges astronomiques, pour lesquelles il est en particulier possible de gérer, selon le principe de l'invention, l'affichage des années en plus de l'affichage des mois, en distinguant, sur un mobile d'affichage des années, les années ordinaires, les années bissextiles, les années séculaires non divisibles par 400 et non bissextiles qui ont un mois de février de 28 jours, et les années séculaires divisibles par 400 et bissextiles dites années quadriséculaires, qui ont des mois de février de 29 jours, ou encore les années quadrimillénaires, qui, quoique théoriquement bissextiles, ont un mois de février de 28 jours.Naturally, the principle of the invention can be extended to other types of calendar timepieces, in particular astronomical watches or astronomical clocks, for which it is in particular possible to manage, according to the principle of the invention. , the display of years in addition to the display of months, distinguishing, on a mobile display of years, ordinary years, years leap years, secular years not divisible by 400 and not leap years which have a 28-day month of February, and secular years divisible by 400 and leap years known as quadrisecular years, which have February months of 29 days, or even quadrimillennial years , which, although theoretically leap, have a 28-day February month.
En somme, grâce à la présente invention, il est possible d'intégrer facilement dans toute pièce d'horlogerie un affichage qui donne à l'utilisateur des renseignements sur le fait de savoir s'il se trouve dans une année bissextile, et/ou, selon l'organisation des index d'affichage, combien d'années sont à décompter jusqu'à la prochaine année bissextile, ou depuis la dernière. On a ainsi connaissance de la durée théorique de mois de février, et du nombre de jours de l'année en cours. L'invention permet un réglage correct des mécanismes de type calendrier perpétuel.In short, thanks to the present invention, it is possible to easily integrate into any timepiece a display which gives the user information on whether he is in a leap year, and / or , depending on the organization of the display indexes, how many years are to be counted down to the next leap year, or since the last. We thus know the theoretical duration of the month of February, and the number of days in the current year. The invention allows correct adjustment of perpetual calendar type mechanisms.
L'invention permet une grande économie de volume dans la boîte de la pièce d'horlogerie concernée. En outre, aucune zone indicatrice supplémentaire n'est nécessaire sur le cadran de la pièce d'horlogerie. Les affichages classiques et essentiels pour un montre-bracelet, comme l'heure et la date, restent parfaitement clairs et lisibles, et dans le premier plan.The invention allows a great saving in volume in the case of the timepiece concerned. In addition, no additional indicator area is required on the dial of the timepiece. Classic and essential displays for a wristwatch, like the time and date, stay perfectly clear and legible, and in the foreground.
L'affichage est conçu selon le principe du calendrier grégorien ou du calendrier julien, est adaptable à tout autre type de calendrier, notamment lunaire. De plus, cet affichage n'est pas temporellement limité, et ne perd pas sa fonction à échéance.The display is designed according to the principle of the Gregorian calendar or the Julian calendar, is adaptable to any other type of calendar, in particular lunar. In addition, this display is not limited in time, and does not lose its function when it expires.
Le mécanisme d'affichage selon l'invention est économique, ainsi que son mécanisme de correction.The display mechanism according to the invention is economical, as is its correction mechanism.
