Description

La présente invention se rapporte à une pièce d'horlogerie comprenant un mécanisme d'affichage annuel ou perpétuel des quantièmes.The present invention relates to a timepiece including an annual or perpetual display mechanism dates.

Les mécanismes connus d'affichage annuel ou perpétuel des quantièmes comportent généralement, outre l'indication des quantièmes, celle du mois en cours d'affichage et des jours de la semaine. A ces indications relatives à la division du temps, basée sur la durée de rotation de la Terre autour du Soleil, sont parfois adjointes des indications relatives à la position d'autres astres par rapport à la Terre, notamment celle de la Lune.Known mechanisms of annual or perpetual display calendars generally include, besides the indication dates, the month of the month being displayed and the days of the week. To these indications relating to the division of time, based on the rotation time of the Earth around the Sun, are sometimes accompanied by indications concerning at the position of other stars in relation to the Earth, especially that of the Moon.

Bien que tout mécanisme annuel ou perpétuel de quantièmes comporte nécessairement une came des mois pour définir le nombre de jours du mois en cours d'affichage, aucun de ces mécanismes ne propose toutefois un dispositif d'affichage pour indiquer combien il y a de jours dans le mois en cours d'affichage. Or, il s'agit là d'une indication extrêmement utile dans la vie de tous les jours.Although any annual or perpetual mechanism of calendars necessarily has a cam of months to define the number of days of the month being displayed, none of these mechanisms does however propose a display device to indicate how many days ago in the month in display course. This is an extremely important indication useful in everyday life.

Le but de la présente invention est de permettre l'utilisation de ce potentiel d'affichage non exploité jusqu'ici.The purpose of the present invention is to enable the use of this display potential not exploited so far.

A cet effet, cette invention a pour objet une pièce d'horlogerie comprenant un mécanisme d'affichage annuel ou perpétuel des quantièmes selon la revendication 1.For this purpose, this invention relates to a part including an annual display mechanism or perpetual calendar according to claim 1.

L'avantage essentiel de cette invention est d'offrir l'affichage d'une indication supplémentaire qui n'était pas encore disponible jusqu'ici pour les mécanismes d'affichage annuel ou perpétuel des quantièmes.The essential advantage of this invention is to offer displaying an additional indication that was not still available so far for display mechanisms annual or perpetual calendars.

De préférence, les moyens pour l'actionnement du dispositif d'affichage de cette pièce d'horlogerie comportent une bascule d'entraínement d'un indicateur de ce dispositif d'affichage, une came des mois du mécanisme des quantièmes, un ressort pour presser la bascule d'entraínement contre la came des mois et une liaison cinématique entre l'élément indicateur et la bascule d'entraínement.Preferably, the means for actuating the device display of this timepiece include a flip-flop of an indicator of this device display, a cam of the months of the date mechanism, a spring to squeeze the drive rocker against the cam of months and a kinematic link between the indicator element and the rocker training.

Ce dispositif comporte très peu de pièces, il est donc simple et fiable.This device has very few parts, so it is simple and reliable.

D'autres particularités de cette invention apparaítront à la lumière de la description qui va suivre et qui sera faite à l'aide du dessin annexé qui illustre, schématiquement et à titre d'exemple, une forme d'exécution de la pièce d'horlogerie objet de la présente invention.Other features of this invention will appear in the light of the following description, which will be made with the aid of the attached drawing which illustrates, schematically and as an example, an embodiment of the piece of horology object of the present invention.

La figure 1 est une vue en plan du mécanisme de calendrier perpétuel de cette pièce d'horlogerie;Figure 1 is a plan view of the calendar mechanism perpetual of this timepiece;

Les figures 2 à 5 sont des vues de dessus partielles du mécanisme de la figure 1 montrant les moyens pour l'actionnement d'un dispositif d'affichage du nombre de jours du mois en cours d'affichage, dans ses quatre positions d'affichage possibles.Figures 2 to 5 are partial top views of the mechanism of Figure 1 showing the means for actuation a device for displaying the number of days of the month being displayed, in its four display positions possible.

Le mécanisme de calendrier de la pièce d'horlogerie objet de la présente invention comporte une roue d'actionnement 1, entraínée à raison de 1 tour par 24 heures dans le sens de la flèche F, par la roue à canon 1b du rouage de minuterie de la pièce d'horlogerie. Cette roue d'actionnement 1 porte une cheville 1a qui sert à entraíner un doigt 2 monté pivotant sur le même axe que la roue d'actionnement 1.The timing mechanism of the timepiece object of the present invention comprises an actuating wheel 1, driven at the rate of 1 turn per 24 hours in the direction of the arrow F, by the clock wheel 1b of the clockwork of the timepiece. This actuating wheel 1 carries a peg 1a which serves to drive a finger 2 mounted pivoting on the same axis as the actuating wheel 1.

Une grande bascule 3 est montée pivotante autour d'un axe 4 et est pressée contre une came des mois 5 par un ressort 6 qui tend à faire tourner cette grande bascule 3 autour de cet axe 4 dans le sens des aiguilles d'une montre. Cette grande bascule 3 sert à commander les principales fonctions du calendrier. A cet effet, elle comporte un bec d'actionnement 3a des jours de la semaine, un premier cliquet d'entraínement 3b d'une roue de quantièmes 7 positionnée par un sautoir 15 qui comporte 31 dents, ainsi qu'un grand cliquet 3c qui coopère avec une came de correction 7a en colimaçon, solidaire de la roue de quantièmes 7.A large rocker 3 is pivotally mounted around a axis 4 and is pressed against a cam of the months 5 by a spring 6 which tends to rotate this large rocker around of this axis 4 in the direction of clockwise. This large rocker 3 serves to control the main calendar functions. For this purpose, it has a beak of actuation 3a days of the week, a first ratchet 3b drive a date wheel 7 positioned by a jumper 15 which has 31 teeth, as well as a large pawl 3c which cooperates with a correction cam 7a spiral, integral with the date wheel 7.

Cette roue de quantièmes 7 porte encore une seconde came 7b en colimaçon contre laquelle appuie une bascule 8, sous la pression d'un ressort 9. Cette bascule 8 porte un cliquet 8a pour entraíner une roue annuelle 10, positionnée par un sautoir 16 solidaire de la came des mois 5. Cette roue annuelle 10 présente douze dents et est entraínée d'un pas à chaque révolution de la roue de quantièmes 7, en sorte qu'elle effectue elle-même une révolution par année.This date wheel 7 still carries a second cam 7b spiral against which presses a rocker 8, under the pressure of a spring 9. This latch 8 carries a ratchet 8a for driving an annual wheel 10, positioned by a jumper 16 integral with the cam of the months 5. This annual wheel 10 has twelve teeth and is driven by a not every revolution of the date wheel 7, so that she herself makes a revolution every year.

Une seconde bascule 11 est pressée par un ressort 12 contre la came des mois 5. Cette seconde bascule 11 présente un secteur denté 11a en prise avec un pignon 13a coaxial à un élément indicateur 13 du dispositif d'affichage du nombre de jours du mois en cours d'affichage, monté pivotant sur un axe 18.A second rocker 11 is pressed by a spring 12 against the cam of the months 5. This second rocker 11 presents a toothed sector 11a engaged with a pinion 13a coaxial with an indicator element 13 of the number display device of days of the month being displayed, pivoted on a axis 18.

La came des mois 5, comme pratiquement toutes les cames des mois des mécanismes perpétuels de quantièmes comporte neuf portions angulaires formées d'une alternance de segments de cercle 5a centrés sur l'axe de la roue annuelle 10 et de portions droites 5b tangentes à un cercle de plus petit diamètre, de sorte que ces segments de cercle 5a et ces portions de droites 5b définissent alternativement deux positions respectives de la seconde bascule 11 et donc également deux positions angulaires respectives de l'élément indicateur 13, selon que le mois en cours d'affichage a 30 ou 31 jours.The cam of the months 5, like almost all the cams months of perpetual mechanisms of date nine angular portions formed of alternating segments of circle 5a centered on the axis of the annual wheel 10 and straight portions 5b tangent to a circle of more small diameter, so these 5a circle segments and these portions of straight lines 5b alternatively define two respective positions of the second latch 11 and therefore also two respective angular positions of the element indicator 13, depending on whether the month being displayed has 30 or 31 days.

En ce qui concerne le mois de février, la came 5 est remplacée par une came 14 qui est solidaire d'un pignon satellite situé sous la roue annuelle 10 et qui engrène avec un pignon fixe coaxial à cette roue annuelle 10. Cette came 14 comporte deux segments, l'un de grand diamètre pour l'affichage du mois de février de 29 jours, qui s'étend sur 90° et l'autre de plus petit diamètre pour l'affichages des mois de février de 28 jours, qui s'étend sur 270°. Cette came 14 est calée sur l'axe de son pignon satellite pour que la portion de petit diamètre vienne en contact avec les extrémités 3e, 11b des bascules 3, respectivement 11 toutes les années où le mois de février a 28 jours, tandis que la portion de grand diamètre de cette came 14 vient en contact avec ces mêmes extrémités des bascules 3 et 11 seulement lors d'années bissextiles, lorsque le mois de février à 29 jours.As for the month of February, the cam 5 is replaced by a cam 14 which is secured to a satellite pinion located under the annual wheel 10 and which meshes with a fixed gear coaxial with this annual wheel 10. This cam 14 has two segments, one of large diameter for display of the month of February of 29 days, which extends over 90 ° and the other of smaller diameter for the month displays February 28 day, which extends over 270 °. This cam 14 is wedged on the axis of its satellite gear so that the small diameter portion comes into contact with the ends 3rd, 11b flip-flops 3, respectively 11 all years when the month of February has 28 days, while the portion large diameter of this cam 14 comes into contact with these same ends of the flip-flops 3 and 11 only in leap years, when the month of February at 29 days.

Les figures 2 à 5 illustrent les quatre positions que peut occuper l'élément indicateur 13 du dispositif d'affichage du nombre de jours du mois en cours d'affichage. Chacune de ces positions angulaires correspond à un chiffre correspondant au nombre de jours du mois en cours d'affichage.Figures 2 to 5 illustrate the four positions that can occupy the indicator element 13 of the display device the number of days in the current month. Each of these angular positions corresponds to a figure corresponding to the number of days in the month being displayed.

A chaque rotation de la roue d'actionnement 1, le doigt 2 entraíne un ergot 3f de la grande bascule 3. La position de cet ergot 3f varie en fonction de la position initiale de cette grande bascule 3 en appui contre la came annuelle 5 ou contre la came de février 14. L'amplitude de la grande bascule 3 est d'autant plus grande que le nombre de jours du mois est faible. De ce fait, à la fin d'un mois de moins de 31 jours, au trentième jour, le grand cliquet 3c vient dans le décrochement de la came de correction 7a, en sorte que lorsque la bascule 3 est entraínée par le doigt 2 de la roue d'actionnement 1, l'indicateur de quantième passe directement du 30 au 1 du mois suivant. Si le mois a 29 jours, l'amplitude de la bascule 3 est encore plus grande et le grand cliquet vient dans le décrochement de la came de correction 7a le 29 déjà et entraíne directement l'indicateur des quantièmes du 29 au 1. Il en est encore de même lorsque le mois a 28 jours. Quel que soit le nombre de jours dans le mois, le grand cliquet 3 remet l'indicateur de quantièmes sur le chiffre 1 pour le début du mois suivant en entraínant la roue de quantièmes d'un, deux, trois ou quatre pas en une fois suivant que le mois a 31, 30, 29 ou 28 jours.With each rotation of the actuating wheel 1, the finger 2 causes a pin 3f of the big rocker 3. The position this ergot 3f varies according to the initial position of this large rocker 3 bearing against the annual cam 5 or against the cam of February 14. The amplitude of the big rocker 3 is even greater than the number of days of the month is low. As a result, at the end of a month less than 31 days, on the thirtieth day, the big ratchet 3c comes in the recess of the correction cam 7a, so that when the rocker 3 is driven by the finger 2 of the wheel 1, the date indicator goes directly from the 30th to the 1st of the following month. If the month is 29 days old, the amplitude of the flip-flop 3 is even greater and the big ratchet comes in the recess of the correction cam 7a the 29 already and drives directly the indicator dates from 29 to 1. It is still the same when the month is 28 days old. Whatever the number of days in the month, the large ratchet 3 sets the date indicator on the number 1 for the beginning of the following month by coaching the date wheel of one, two, three or four steps in one once the month is 31, 30, 29 or 28 days.

A la fin de chaque entraínement de la roue de quantièmes par le grand cliquet 3c à la fin de chaque mois, la bascule 8 tombe dans le décrochement de la came 7b, entraínant d'un pas la roue annuelle 10. La bascule 3 prend une autre position si le nombre de jours du mois suivant change et il en est de même pour la seconde bascule 11 du dispositif indicateur du nombre de jours du mois, provoquant le positionnement de l'élément indicateur 13 vis-à-vis du chiffre correspondant au nombre de jours du mois en cours d'affichage.At the end of each drive of the date wheel by the big ratchet 3c at the end of each month the rocker 8 falls into the recess of the cam 7b, training the annual wheel by 10. The rocker 3 takes a other position if the number of days of the following month changes and it is the same for the second flip-flop 11 of the device indicator of the number of days of the month, causing the positioning of the indicator element 13 vis-à-vis the number corresponding to the number of days in the month being displayed.
