Description

La présente invention se rapporte aux pièces d'horlogerie à affichage du quantième. Elle concerne, plus particulièrement, un mécanisme indicateur de quantième instantané pour un mouvement de montre.The present invention relates to timepieces with display of calendar. It relates, more particularly, to a mechanism indicating instantaneous date for a watch movement.

On rappellera qu'un tel mécanisme permet d'effectuer, à minuit, le passage instantané du quantième. Chaque soir, l'énergie d'un ressort, armé depuis quelques heures par une roue 24 heures, est restituée brusquement pour faire avancer d'un pas l'indicateur de quantième, à couronne ou à aiguille.It will be recalled that such a mechanism makes it possible, at midnight, to pass through snapshot of the date. Each evening, the energy of a spring, armed since a few hours by a 24-hour wheel, is suddenly returned to make advance the date indicator, crown or hand, one step.

Bien que le positionnement de l'indicateur de quantième soit assuré par un sautoir, il peut arriver que la gifle reçue à minuit lui fasse faire un double saut, ce qui, évidemment, réduit fortement l'intérêt d'un mécanisme instantané.Although the positioning of the date indicator is ensured by a long necklace, it may happen that the slap received at midnight makes him make a double jump, which, of course, greatly reduces the value of an instant mechanism.

Il est donc impératif, pour une montre de qualité, que le mécanisme soit totalement exempt du risque de double saut de l'indicateur de quantième. De plus, ce mécanisme doit, non seulement, permettre d'effectuer une correction rapide de la date mais aussi, cela va de soi, être de construction aussi fiable, robuste et peu coûteuse que possible.It is therefore imperative, for a quality watch, that the mechanism be completely free from the risk of double jump of the date indicator. Of more, this mechanism must, not only, allow to carry out a correction fast of the date but also, it goes without saying, to be of construction as reliable, robust and inexpensive as possible.

La présente invention a pour but, justement, de fournir un mécanisme de quantième instantané répondant aux exigences énoncées ci-dessus.The present invention aims, precisely, to provide a mechanism for instantaneous calendar meeting the requirements set out above.

De façon plus précise, l'invention concerne un mécanisme instantané pour la commande de l'indicateur de quantième d'un mouvement de pièce d'horlogerie, caractérisé en ce qu'il comporte :

  • une roue 24 heures entraínée par le mouvement à raison d'un tour par jour et percée d'une première découpe,
  • une roue entraíneuse de quantième montée libre en rotation sur la roue 24 heures, coaxialement à elle, ladite roue possédant une goupille qui prend place dans la découpe et une dent qui coopère avec l'indicateur pour le faire progresser pas à pas chaque jour vers minuit, et
  • une bascule ressort coopérant avec la goupille.
More specifically, the invention relates to an instantaneous mechanism for controlling the date indicator of a timepiece movement, characterized in that it comprises:
  • a 24-hour wheel driven by the movement at the rate of one revolution per day and pierced with a first cut,
  • a driving date wheel mounted free in rotation on the 24-hour wheel, coaxially with it, said wheel having a pin which takes place in the cutout and a tooth which cooperates with the indicator to make it progress step by step every day around midnight , and
  • a spring lever cooperating with the pin.

Selon l'invention, ces organes sont conformés, dimensionnés et disposés de manière à effectuer le cycle des opérations suivantes :

  • quelques heures avant minuit, la goupille commence à agir sur la bascule, alors dans sa position de repos, en armant son ressort ;
  • vers minuit, la bascule échappe à la goupille et revient brusquement à sa position de repos en lançant vers l'avant la goupille et la roue entraíneuse dont la dent vient gifler l'indicateur de quantième pour le faire avancer d'un pas; et
  • quelques heures après minuit, la goupille est rattrapée par la découpe de la roue 24 heures et poussée jusqu'à revenir, quelques heures avant minuit, au contact de la bascule.
According to the invention, these members are shaped, dimensioned and arranged so as to carry out the cycle of the following operations:
  • a few hours before midnight, the pin begins to act on the rocker, then in its rest position, by arming its spring;
  • around midnight, the rocker escapes the pin and suddenly returns to its rest position by throwing the pin and the driving wheel forward, the tooth of which slaps the date indicator to advance it by one step; and
  • a few hours after midnight, the pin is caught by cutting the wheel 24 hours and pushed until returning, a few hours before midnight, in contact with the scale.

Selon un mode de réalisation particulièrement avantageux, la première découpe est en arc de cercle concentrique à la roue 24 heures. Cette découpe est, par ailleurs, le prolongement d'une deuxième découpe libérant un doigt ressort et débouche sur le bout de ce doigt.According to a particularly advantageous embodiment, the first cutout is in an arc concentric with the wheel 24 hours. This cutting is, moreover, the extension of a second cutting releasing a finger comes out and opens on the tip of this finger.

D'autres caractéristiques de l'invention ressortiront de la description qui va suivre, faite en regard du dessin annexé dans lequel :

  • les figures 1, 2, 3 et 4 représentent le mécanisme dans les positions qu'il occupe respectivement à 20 H, juste avant le saut de minuit, juste après le saut de minuit et à 6 H ; et
  • la figure 5 est une vue de la roue 24 heures du mécanisme.
Other characteristics of the invention will emerge from the description which follows, given with reference to the appended drawing in which:
  • Figures 1, 2, 3 and 4 show the mechanism in the positions it occupies respectively at 8 p.m., just before midnight jump, just after midnight jump and at 6 a.m .; and
  • Figure 5 is a view of the 24 hour wheel of the mechanism.

De manière classique, le mécanisme selon l'invention est monté sur une platine servant aussi de base aux composants du mouvement de la montre. La platine n'est pas représentée au dessin car ce type de construction est bien connu de l'homme de métier.Conventionally, the mechanism according to the invention is mounted on a plate also serving as a base for the components of the watch movement. The plate is not shown in the drawing because this type of construction is well known to those skilled in the art.

Sur les figures, on a représenté en 10 une roue 24 heures entraínée dans le sens des aiguilles d'une montre (flèche F) à raison d'un tour par jour à partir de la roue des heures du mouvement. Comme le montre mieux la figure 5, cette roue est percée d'une découpe 12 en deux portions communicantes. La portion 12a sert à libérer un doigt ressort 14 en épingle à cheveux, tandis que la portion 12b prolonge la portion 12a à partir du bout 14a du doigt 14 et forme un arc de cercle concentrique à la roue 10. Son extrémité porte la référence 12c. Dans l'exemple représenté, l'écart angulaire entre l'extrémité 12c de la découpe et l'extrémité 14a du doigt est de l'ordre de 90°.In the figures, there is shown at 10 a 24-hour wheel driven in the clockwise (arrow F) one revolution per day from of the hour wheel of the movement. As best shown in Figure 5, this wheel is pierced with a cutout 12 into two communicating portions. The portion 12a serves to release a hairpin spring finger 14, while the portion 12b extends the portion 12a from the tip 14a of the finger 14 and forms an arc of a circle concentric with the wheel 10. Its end bears the reference 12c. In the example shown, the angular difference between the end 12c of the cutting and the end 14a of the finger is of the order of 90 °.

Une deuxième roue 16, appelée roue entraíneuse de quantième, est montée, libre en rotation, sur la roue 24 heures 10, coaxialement à elle. Cette roue porte, à sa périphérie, une goupille 18 dimensionnée pour prendre place et se déplacer dans la portion 12b de la découpe 12. Elle possède également, à l'arrière de la goupille 18, une dent extérieure 20 conformée pour coopérer avec les trente-et-une dents 22 d'une couronne de quantième 24. Dans l'exemple représenté, l'écart angulaire entre la goupille 18 et la dent 20 est de l'ordre de 45°.A second wheel 16, called the date driving wheel, is mounted, free to rotate, on the 24 hour wheel 10, coaxially with it. This wheel carries, at its periphery, a pin 18 sized to take place and is move in the portion 12b of the blank 12. It also has, at the rear of the pin 18, an outer tooth 20 shaped to cooperate with the thirty-one teeth 22 of a date crown 24. In the example shown, the angular difference between the pin 18 and the tooth 20 is around 45 °.

Le mécanisme selon l'invention comporte encore une bascule 26 sous la forme d'un levier monté pivotant autour d'un axe 28 et présentant un coude 30 qui forme, typiquement, un angle d'environ 135° et contre le flanc amont 30a duquel la goupille 18 de la roue 16 vient s'appliquer et glisser de manière à faire pivoter la bascule dans le sens inverse des aiguilles d'une montre (flèche Le levier 26 se prolonge, au delà de son axe 28, par un ressort 32 recourbé en épingle à cheveux et dont l'extrémité est en appui contre un plot 34.The mechanism according to the invention also comprises a rocker 26 under the form of a lever mounted pivoting about an axis 28 and having a bend 30 which typically forms an angle of about 135 ° and against the upstream flank 30a which the pin 18 of the wheel 16 comes to apply and slide so as to rotate the scale counterclockwise (arrow The lever 26 is extended, beyond its axis 28, by a curved spring 32 hairpin and the end of which bears against a stud 34.

Le flanc aval 30b du coude sert, au contraire, à propulser la goupille vers l'avant, comme cela sera mieux décrit plus bas.On the contrary, the downstream side 30b of the elbow serves to propel the pin towards the front, as will be better described below.

Enfin, le mécanisme comporte, de manière classique, un sautoir et son ressort (non représentés) assurant le positionnement de la couronne de quantième 24.Finally, the mechanism comprises, in a conventional manner, a jumper and its spring (not shown) ensuring the positioning of the crown date 24.

Le fonctionnement du mécanisme selon l'invention va être maintenant décrit en se référant successivement aux figures 1, 2, 3 et 4. The operation of the mechanism according to the invention will now be described referring successively to Figures 1, 2, 3 and 4.

Vers 20H, comme représenté sur la figure 1, la goupille 18, entraínée par l'extrémité 12c de la découpe de la roue 10, arrive au contact du flanc amont 30a du coude 30 qu'il commence à pousser. Le levier 26, qui était dans sa position de repos, se met donc à pivoter selon f en armant le ressort 32, alors que la goupille glisse sur le flanc 30a en direction du sommet du coude.Around 8 p.m., as shown in Figure 1, the pin 18, driven by the end 12c of the cutout of the wheel 10, comes into contact with the upstream side 30a of the elbow 30 that it starts to push. Lever 26, which was in its rest position, therefore starts to pivot along f by arming the spring 32, then that the pin slides on the side 30a in the direction of the top of the elbow.

A minuit, comme le montre la figure 2, la goupille 18 passe sur le flanc aval 30b du coude. C'est alors le levier 26 qui prend le dessus et, sous l'effet de son ressort 32, armé au maximum, retombe brusquement dans sa position de repos, illustrée par la figure 3. Le flanc aval 30b lance ainsi vers l'avant la goupille 18 et la roue entraíneuse 16 dont la dent 20 vient gifler une dent 22 de la couronne de quantième 24 et fait donc avancer celle-ci d'un pas.At midnight, as shown in Figure 2, the pin 18 passes on the downstream side 30b of the elbow. It is then the lever 26 which takes over and, under the effect of its spring 32, fully armed, suddenly drops back into its position rest, illustrated by FIG. 3. The downstream flank 30b thus launches forward the pin 18 and driving wheel 16, the tooth 20 of which slaps a tooth 22 of the date crown 24 and therefore advances it by one step.

Il est important de remarquer que la goupille 18 vient buter sur l'extrémité 14a du doigt ressort 14, empêchant ainsi que, dans son élan, la dent 20 de la roue 16 fasse effectuer un deuxième saut à la couronne de quantième 24.It is important to note that the pin 18 abuts on the end 14a of the spring finger 14, thus preventing the tooth 20 of the wheel in its tracks 16 causes the calendar crown 24 to jump a second time.

Enfin, vers 6H, comme illustré par la figure 4, la goupille 18 - qui n'a pas bougé depuis minuit car elle n'était plus poussée par la roue 10 - est rattrapée par l'extrémité 12c de la découpe 12. Elle va ainsi être entraínée, avec sa roue 16, jusqu'à, vers 20H, venir buter sur le flanc amont 30a du coude 30 pour se retrouver dans la configuration de la figure 1.Finally, around 6H, as illustrated in Figure 4, the pin 18 - which has not moved since midnight because it was no longer pushed by the wheel 10 - is caught by the end 12c of the cutout 12. It will thus be driven, with its wheel 16, until, around 8 p.m., come up against the upstream side 30a of the elbow 30 to find yourself in the configuration of Figure 1.

Un nouveau cycle, identique à celui qui vient d'être décrit, commence alors.A new cycle, identical to that which has just been described, then begins.

Tout au long de la journée, rien ne s'opposera à une correction rapide du quantième, effectuée, de manière classique, en agissant directement sur les dents 22 de la couronne 24. En effet, la rotation de la roue 16, poussée par les dents 22, n'est pas interdite puisque, au moment où la goupille 18 bute sur l'extrémité14a du doigt ressort 14, celui-ci s'escamote.Throughout the day, nothing will stand in the way of a rapid correction of the date, carried out, in a conventional manner, by acting directly on the teeth 22 of the crown 24. Indeed, the rotation of the wheel 16, pushed by teeth 22 is not prohibited since, when the pin 18 abuts on the end 14a of the spring finger 14, the latter retracts.

Ainsi est proposé un mécanisme indicateur de quantième instantané qui est pleinement protégé contre le risque de double saut et permet d'effectuer une correction rapide de la date. On notera aussi que ce mécanisme est essentiellement constitué de trois organes seulement: une roue 24 heures découpée, une roue entraíneuse et une bascule. Il s'agit de pièces à la fois simples à réaliser, donc peu coûteuses, et susceptibles d'assurer un fonctionnement très fiable du mécanisme.Thus is proposed an instantaneous date indicator mechanism which is fully protected against the risk of double jump and allows rapid date correction. Note also that this mechanism is essentially consisting of only three components: a 24-hour wheel cut, a driving wheel and a rocker. These are parts at a time simple to make, therefore inexpensive, and capable of ensuring very reliable operation of the mechanism.
