Abstract

The date has a last wheel (13) effectuating a turn for 400 years and carrying a cam (13`) that comprises step pins co-operating with a lever (9). A wheel (6) carrying a planet gear (7`) is pivoted on the lever, and a February month cam (7) is fixed on the gear. The cam (13`) effectuates a quarter turn for each century and presents three low step pins. The low step pins permit the lever to be moved back so that the cam (7) is found in same position for a February month of 28 days for years 2100, 2200 and 2300. The cam (13`) presents a high step pin to restore the 29 February for the year 2400.

Description

L'invention a pour objet un quantième perpétuel séculaire pour pièce d'horlogerie, notamment pour montre-bracelet.
Une recherche effectuée par la titulaire a permis de relever les deux antériorités suivantes :

  • le brevet suisse n° 653 841 ainsi que le brevet allemand DE-31294 . ces deux brevets décrivent des quantièmes perpétuels séculaires et représentent l'état de la technique.
The subject of the invention is a perpetual perpetual calendar for a timepiece, particularly for a wristwatch.
A search conducted by the licensee revealed two prior art references:
  • the patent Swiss Art No 653 841 as well as the German patent DE-31294 . these two patents describe secular perpetual calendars and represent the state of the art.

Le mécanisme décrit dans le brevet allemand n° 31294 est plutôt destiné à être utilisé dans une pendule et son utilisation dans une montre-bracelet est peu réaliste. Par contre le brevet suisse n° 653 841 au nom de Pateck Philips SA décrit un mécanisme plus sophistiqué. Dans ce mécanisme, le rouage qui coopère avec la came séculaire est entraîné en rotation par la came du mois à raison d'un tour en cent ans. Sur ce rouage effectuant un tour en cent ans est monté un satellite à quatre branches qui fait un quart de tour chaque cent ans. Ce satellite se présente sous la forme d'une croix de malte, ce qui peut occasionner quelques problèmes lors du fonctionnement.The mechanism described in the patent Germanic No. 31294 is rather intended to be used in a pendulum and its use in a wristwatch is unrealistic. On the other hand, the patent Swiss Art No 653 841 in the name of Pateck Philips SA describes a more sophisticated mechanism. In this mechanism, the gear that cooperates with the secular cam is rotated by the cam of the month at a rate of one turn in one hundred years. On this cog, making a turn in one hundred years is mounted a four-spoke satellite that makes a quarter turn every hundred years. This satellite is in the form of a Maltese cross, which can cause some problems during operation.

Le but de la présente invention est de proposer un quantième perpétuel séculaire dont le rouage séculaire portant la came est agencé pour effectuer un tour tous les quatre cents ans.The object of the present invention is to provide a secular perpetual calendar whose age-old gear carrying the cam is arranged to perform a turn every four hundred years.

Le quantième perpétuel séculaire pour pièce d'horlogerie, notamment pour montre-bracelet selon l'invention, comprenant un mécanisme de quantième perpétuel rétrograde classique est caractérisé en ce qu'un mécanisme additionnel est relié au mécanisme de quantième perpétuel classique et comprend une dernière roue effectuant un tour en quatre cents ans, cette roue portant une came dont les échelons coopèrent avec une bascule sur laquelle pivote une roue qui porte un satellite sur lequel est fixé la came des mois de février, la came qui effectue un quart de tour chaque siècle présentant trois échelons bas permettant à la bascule de reculer de manière à ce que la came sur laquelle va venir s'appuyer le levier multiple se trouve dans la même position que pour un mois de février de 28 jours classique trois fois de suite pour les années 2100, 2200, 2300, puis un échelon haut de manière à rétablir le 29 février de l'année 2400. Lorsque 1 montre-bracelet comprenant le quantième perpétuel séculaire sera mise sur le marché prochainement, le mécanisme de quantième séculaire effectuera par conséquent sa première correction en 2400.The perpetual perpetual calendar for a timepiece, particularly for a wristwatch according to the invention, comprising a conventional retrograde perpetual calendar mechanism is characterized in that an additional mechanism is connected to the classic perpetual calendar mechanism and includes a last wheel making a turn in four hundred years, this wheel carrying a cam whose steps cooperate with a rocker on which pivots a wheel which carries a satellite on which is fixed the cam of the months of February, the cam which makes a quarter turn every century with three low steps allowing the rocker to move back so that the cam on which will come to rest the multiple lever is in the same position as for a month of February of 28 days classic three times in a row for the years 2100, 2200, 2300, then a step high so as to restore the 29 February of the year 2400. When a wristwatch including the perpetual calendar perpetual will be placed on the market soon, the secular calendar mechanism will therefore perform its first correction in 2400.

Selon un mode d'exécution préféré, une roue engrenant avec la roue effectuant un tour tous les quatre cents ans porte un double doigt dont la fonction est de rétablir après le mois de février de l'année centenaire, le rythme normal du calendrier pendant les 99 années suivantes en faisant avancer la roue de quatre cents ans, et donc la came fixée sur cette roue de 1/8ème de tour.According to a preferred embodiment, a wheel meshing with the wheel making a turn every four hundred years carries a double finger whose function is to restore after the month of February of the centenary year, the normal rhythm of the calendar during the next 99 years by advancing the wheel of four hundred years, and thus the cam fixed on this wheel of 1/8 th of a turn.

Un palpeur d'une bascule vient s'appuyer sur la came reliée à la roue de quatre cents ans de manière à modifier sa position angulaire et, par conséquent, durant chaque mois de février, corrigé ou non, selon que l'année séculaire ou pas, le nombre de jours du mois en fonction de la position de la came solidaire de la roue 13.A probe of a rocker comes to rest on the cam connected to the wheel of four hundred years so as to modify its angular position and, consequently, during each month of February, corrected or not, according to whether the year secular or not, the number of days of the month depending on the position of the cam secured to the wheel 13.

La correction effectuée tous les quatre ans par un quantième perpétuel conventionnel est trop importante selon le calendrier grégorien et le quantième perpétuel séculaire selon le dessin est agencé pour maintenir l'année bissextile tous les quatre cents ans, c'est-à-dire chaque siècle dont les deux premiers en chiffre sont divisibles par quatre, en d'autres mots l'année 2000, 2400, 2800, etc...The correction made every four years by a conventional perpetual calendar is too important according to the Gregorian calendar and the perpetual perpetual calendar according to the drawing is arranged to maintain the leap year every four hundred years, that is to say each century whose the first two in number are divisible by four, in other words the year 2000, 2400, 2800, etc ...

Ainsi, à chaque siècle intermédiaire 2100, 2200, 2300 et 2500, 2600, 2700, etc.... l'année bissextile est supprimée.Thus, in each intermediate century 2100, 2200, 2300 and 2500, 2600, 2700, etc .... the leap year is removed.

Le quantième perpétuel séculaire représenté dans le dessin comprend une série de rouage et de cames 4, 5, 6, 7, 7', 8, 9, 10, 11, 11', 12, 12', 13, 13', 14, un palpeur 2 pivotant autour de l'axe 16 et commandé par la roue de la date 3 et sa came 3' et la roue de 24 heures 1 et sa came 1'.The perpetual perpetual calendar represented in the drawing comprises a series of wheels and cams 4, 5, 6, 7, 7 ', 8, 9, 10, 11, 11', 12, 12 ', 13, 13', 14, a probe 2 pivoting about the axis 16 and controlled by the wheel of the date 3 and its cam 3 'and the wheel 24 hours 1 and its cam 1'.

Partant d'un quantième perpétuel conventionnel dans lequel on tient compte dans un cycle de 4 ans, de 3 ans consécutifs avec un mois de février de 28 jours et 1 fois tous les 4 ans, d'un mois de février de 29 jours.
Partant de cette base, nous avons un rouage dont la dernière roue 13 de 8 dents tourne en quatre cents ans. Cette dernière roue 13 porte une came circulaire 13' avec 3 encoches ayant chacune une valeur de 1/8ème de tour (voir fig.8).Starting from a conventional perpetual calendar in which one takes into account in a cycle of 4 years, of 3 consecutive years with a month of February of 28 days and 1 time every 4 years, of a month of February of 29 days.
From this base, we have a wheel whose last wheel 13 of 8 teeth turns in four hundred years. This last wheel 13 carries a cam circular 13 'with 3 notches each having a value of 1/8 th of a turn (see fig.8).

Position 2 février séculaire (figure 4) Secular 2 February Position (Figure 4)

Le palpeur 15 du levier multiple 2 vient en appui sur l'échelon bissextile de la came satellite 7'. Pour modifier le 29 février en 28 jours (2100, 2200 et 2300 etc...) la came 13' est positionnée pour que le palpeur 14 vienne en appui sur une encoche obligeant la bascule 9 à reculer de la valeur d'un échelon 29 - 28.The probe 15 of the multiple lever 2 abuts on the leap step of the satellite cam 7 '. To modify the February 29 in 28 days (2100, 2200 and 2300 etc ...) the cam 13 'is positioned so that the probe 14 comes to bear on a notch forcing the rocker 9 to move back the value of a step 29 - 28.

Il est important que la came 13' reprenne avant le mois de février suivant, une position présentant le plus grand diamètre pour afficher le 29 février dans le cycle normal de quatre ans.It is important that the cam 13 'resume before the following February, a position with the largest diameter to display February 29 in the normal cycle of four years.

En résumé, les petits échelons de la came 13' ne se présenteront au palpeur 14 que 28 jours ou plus, mais moins de 11 mois par siècle trois fois de suite.In summary, the small steps of the cam 13 'will only occur at the probe 14 28 days or more, but less than 11 months per century three times in a row.

Explication des rouages bissextilesExplanation of leap gear

La roue 4, qui est la roue des mois, tourne avec la came 4' et l'étoile 4'' en un an. La came 4' présente un échelon février très profond ( plus que sa valeur utile). Cette étoile 4" est solidaire de la roue 4 destinée à entraîner le renvoi 5.The wheel 4, which is the wheel of the months, rotates with the cam 4 'and the star 4' 'in one year. Cam 4 'has a very deep step February (more than its useful value). This star 4 "is secured to the wheel 4 intended to cause the return 5.

Ce dernier entraîne la roue 6 qui a le même nombre de dents que la roue 4 et fait donc un tour en an.The latter drives the wheel 6 which has the same number of teeth as the wheel 4 and thus makes a turn in a year.

Sur l'axe de cette roue, le pignon fixe 8 est solidaire de la bascule 9 qui pivote en 16.On the axis of this wheel, the fixed gear 8 is integral with the rocker 9 which pivots at 16.

Le pignon 7 est ajusté librement sur un bras de la roue 6 est ainsi satellisé autour du pignon 8 avec un rapport d'engrenage qui lui fait faire 1 tour ¼ par année.The pinion 7 is freely adjusted on an arm of the wheel 6 is thus orbited around the pinion 8 with a gear ratio that makes him make 1 turn ¼ per year.

Sur ce dernier est fixée une came satellite 7' dont ¼ de la circonférence a un diamètre plus grand pour les mois de 29 jours. Chaque année, la came présente un écart de 90° par rapport à un point déterminé sur lequel viendra s'appuyer le levier multiple 2 pendant toute la durée du mois de février. Le système du réglage des fins de mois est classique. Un cliquet pour la date et un cliquet auxiliaire de fin des mois.On the latter is fixed a satellite cam 7 'of which ¼ of the circumference has a larger diameter for the months of 29 days. Each year, the cam has a 90 ° deviation from a given point on which will support the multiple lever 2 throughout the duration of February. The month-end adjustment system is classic. A ratchet for the date and an auxiliary ratchet at the end of the month.

Rouage séculaire :Secular gear:

L'étoile 4" est l'étoile des mois, elle avance de 1/12ème de tour chaque mois, donc 1 tour en 1 an. Sur cette roue est fixée la came des mois 4' à 12 échelons de profondeurs différentes pour régler la longueur irrégulière des fins de mois (système classique).
Sur l'étoile 4'' est fixé un disque portant un doigt 17. Au passage du 31 janvier au 1er février, ce doigt entraîne une dent de la roue 10. Il reste engagé entre 2 dents (sur la ligne du centre).
Le 28 et 29 février, à minuit, en avançant d'une dent, le doigt 17 entraîne une 2ème dent de la roue 10 et sort de son périmètre et le cycle recommence le 31 janvier suivant. La roue 10 qui a 20 dents va donc faire un tour en 10 ans.
L'entraînement de la roue 11 est dans son principe identique. C'est-à-dire qu'elle a 20 dents et tous les 10 ans avance de 2 dents, entraînées par un doigt fixé sur la roue 10. Elle va donc faire un tour en 100 ans.
La roue 12 a 12 dents. Elle est entraînée par un secteur 11' de 11 dents, fixé sur la roue 11 qui va entraîner 2 dents 6 fois de suite, donc 1 tour complet en 60 ans et rester immobile pendant 40 ans, jusqu'à ce qu'une nouvelle dent du secteur se présente. Elle va donc faire un tour en 100 ans.The Star 4 "is the star of the month, she lead 1/12 th lap each month, thus 1 revolution in 1 year. On this wheel is fixed cam 4 months to 12 levels of different depths to adjust the irregular length of the end of the month (classic system).
The star 4 '' set a disc carrying a finger 17. In passing from January 31 to February 1, this finger leads to a tooth of the wheel 10. It remains engaged between two teeth (the center line).
On 28 and 29 February, at midnight, advancing a tooth, the finger 17 drives a 2nd tooth of the wheel 10 and leaves its perimeter and the cycle repeats the following 31 January. The wheel 10 which has 20 teeth will therefore make a turn in 10 years.
The drive of the wheel 11 is in principle identical. That is to say that it has 20 teeth and every 10 years advances of 2 teeth, driven by a finger fixed on the wheel 10. It will therefore take a turn in 100 years.
The wheel 12 has 12 teeth. It is driven by a sector 11 'of 11 teeth, fixed on the wheel 11 which will lead 2 teeth 6 times in succession, so 1 complete turn in 60 years and remain motionless for 40 years, until a new tooth the sector presents itself. She will go for a ride in 100 years.

Sur la roue 12 est fixé un double doigt 12' qui va entraîner 2 fois consécutives, à un mois d'intervalle, chaque 100 ans la roue 13 qui a 8 dents et fait donc 1 tour en 400 ans (voir fig. 1). Cette dernière porte la came 13' (voir fig. 4, explication planche position 28 février séculaire) qui coopère avec le bec 14 de la bascule 9.On the wheel 12 is fixed a double finger 12 'which will cause 2 consecutive times, one month apart, every 100 years the wheel 13 which has 8 teeth and thus makes 1 turn in 400 years (see Fig. 1). The latter carries the cam 13 '(see Fig. 4, explanation plate position February 28 secular) which cooperates with the spout 14 of the rocker 9.

A l'exception des années séculaires, le bec 14 de la bascule 9 est toujours en appui sur l'échelon haut de la came 13'. Lors des années séculaires, la came au 1er février présente 3 fois de suite un échelon bas au bec 14, obligeant la bascule 9 à reculer de manière à transformer le 29 février en 28 pour les années 2100, 2200, 2300. La 4ème fois, soit pour l'année 2400, la came présente un échelon haut de manière à rétablir l'année bissextile (voir fig.1).With the exception of secular years, the spout 14 of the rocker 9 is still resting on the top rung of the cam 13 '. During the secular years, the cam 1 February this 3 times a low level to the spout 14, forcing the flip-flop 9 to back so as to convert February 29 in 28 for the years 2100, 2200, 2300. The 4 th times, for the year 2400, the cam has a step up to restore the leap year (see fig.1).
