Description

MECANISME DE COMMANDE DES FONCTIONS D'UN MOUVEMENT DE MONTRE MECHANISM FOR CONTROLLING THE FUNCTIONS OF A WATCH MOVEMENT
La présente invention se rapporte aux mouvements de pièces d'horlogerie mécaniques ou électromécaniques. Elle concerne, plus particulièrement, un mécanisme de commande des fonctions de telles pièces.The present invention relates to movements of mechanical or electromechanical timepieces. It relates, more particularly, to a mechanism for controlling the functions of such parts.
Les constructeurs horlogers souhaitent disposer de mouvements de base leur offrant la possibilité d'afficher, au choix et de manière originale, les diverses fonctions du temps (heure, minute, quantième, jour, .... ), sans qu'il soit nécessaire de procéder à de lourdes adaptations du mouvement.Watch manufacturers want basic movements that allow them to display, as desired and in an original way, the various time functions (hours, minutes, calendar, day, etc.), without it being necessary. to make heavy adjustments to the movement.
La présente invention a pour but de répondre à un tel souhait.The present invention aims to respond to such a wish.
Pour atteindre ce but, l'invention propose un mécanisme de commande des fonctions d'une pièce d'horlogerie, qui comporte : - une roue entraîneuse actionnée par le mouvement de la pièce, - une came circulaire couplée à un organe de fonction, - une première bascule portant une roue et capable d'occuper des première et deuxième positions pour lesquelles une liaison cinématique est respectivement réalisée ou non réalisée entre la roue entraîneuse, cette roue de bascule et la came , et - des moyens de déclenchement capables de mettre cycliquement ladite bascule dans ses première et deuxième positions.To achieve this object, the invention provides a mechanism for controlling the functions of a timepiece, which comprises: - a driving wheel actuated by the movement of the piece, - a circular cam coupled to a function member, - a first rocker carrying a wheel and capable of occupying first and second positions for which a kinematic connection is respectively made or not made between the driving wheel, this rocker wheel and the cam, and - trigger means capable of cyclically setting said rocker in its first and second positions.
De façon particulièrement avantageuse, les moyens de déclenchement comportent une deuxième bascule actionnant la première bascule et un déclencheur actionné cycliquement par le mouvement et actionnant la deuxième bascule.In a particularly advantageous manner, the triggering means comprise a second rocker actuating the first rocker and a trigger actuated cyclically by the movement and actuating the second rocker.
D'autres caractéristiques de l'invention ressortiront de la description qui va suivre, faite en regard du dessin annexé, dans lequel : - les figures 1 à 5 représentent le mécanisme à différents instants de son fonctionnement ; et - la figure 6 illustre diverses réalisations de la came de ce mécanisme.Other characteristics of the invention will emerge from the description which follows, given with reference to the appended drawing, in which: - Figures 1 to 5 show the mechanism at different times of its operation; and - Figure 6 illustrates various embodiments of the cam of this mechanism.
Sur les figures, on a montré en 10 une roue entraîneuse, elle-même entraînée dans le sens horaire à partir d'un barillet (non représenté), typiquement à raison d'un tour par heureIn the figures, there is shown at 10 a driving wheel, itself driven clockwise from a barrel (not shown), typically at the rate of one revolution per hour.
Une première bascule 11 , en forme de faucille, est montée pivotante sur un axe 12. Sa portion en demi-cercle 13 porte une dent 14 et, à son extrémité opposée à l'axe 12, une roue de bascule 15.A first rocker 11, in the form of a sickle, is pivotally mounted on an axis 12. Its semicircular portion 13 carries a tooth 14 and, at its end opposite the axis 12, a rocker wheel 15.
La dent 14 est positionnée et conformée de manière à pouvoir engrener avec la denture d'une came circulaire 16 concentrique à la portion en demi-cercle 13. Dans le mode de réalisation représenté au dessin, la came 16 comporte trente-et-une dents.The tooth 14 is positioned and shaped so as to be able to mesh with the teeth of a circular cam 16 concentric with the semicircular portion 13. In the embodiment shown in the drawing, the cam 16 has thirty-one teeth .
La roue de bascule 15 est positionnée et conformée de manière à pouvoir engrener avec la roue 10. On notera que l'axe 12 de la bascule 11 , l'axe de la came 16 et l'axe de la roue de bascule 15 sont sensiblement alignés.The rocker wheel 15 is positioned and shaped so as to be able to mesh with the wheel 10. It will be noted that the axis 12 of the rocker 11, the axis of the cam 16 and the axis of the rocker wheel 15 are substantially aligned.
La came circulaire 16 est liée, au-dessous d'elle, à une roue de même axe 17 engrenant en permanence avec la roue de bascule 15 et portant une aiguille 18 se déplaçant sur un cadran (non représenté) pour y désigner les trente-et- un quantièmes du mois.The circular cam 16 is linked, below it, to a wheel of the same axis 17 permanently meshing with the rocking wheel 15 and carrying a needle 18 moving on a dial (not shown) to designate the thirty- and- a calendar of the month.
La bascule en faucille 11 est associée à un ressort 19 qui, avec l'aide d'un plot 20, travaille de manière à rapprocher de la came 16 sa portion en demi- cercle 13.The sickle rocker 11 is associated with a spring 19 which, with the help of a stud 20, works so as to bring the semi-circle portion 13 closer to the cam 16.
Une deuxième bascule 21 , montée pivotante sur la première bascule 11 autour d'un axe 22, est dotée de trois bras 23, 24 et 25.A second lever 21, pivotally mounted on the first lever 11 around an axis 22, is provided with three arms 23, 24 and 25.
Le premier bras 23 se termine par une dent 26 positionnée et conformée de manière à coopérer avec le pourtour de la came 16, avec un décalage tel que cette dent et la dent 14 de la première bascule 11 ne soient jamais toutes les deux en prise avec la came. Les deuxième et troisième bras 24 et 25 forment une sorte de fourche à l'opposé du premier bras 23.The first arm 23 ends with a tooth 26 positioned and shaped so as to cooperate with the periphery of the cam 16, with an offset such that this tooth and the tooth 14 of the first rocker 11 are never both engaged with drug. The second and third arms 24 and 25 form a sort of fork opposite the first arm 23.
Le deuxième bras 24 est disposé de manière à coopérer avec un doigt 27 entraîné dans le sens horaire par un mobile déclencheur 28 qui, dans le mode de réalisation représenté, est lui-même entraîné, à partir du barillet, à raison d'un tour !par jour.The second arm 24 is arranged so as to cooperate with a finger 27 driven clockwise by a trigger mobile 28 which, in the embodiment shown, is itself driven, from the barrel, at the rate of one revolution ! per day.
Le troisième bras 25 est positionné et conformé de manière à limiter les déplacements de la bascule 21 en venant en butée contre la came 16.The third arm 25 is positioned and shaped so as to limit the movements of the rocker 21 coming into abutment against the cam 16.
Pour décrire la manière dont fonctionne le mécanisme selon l'invention, on se référera successivement aux figures 1 , 2, 3, 4 et 5.To describe the way in which the mechanism according to the invention operates, reference will be made successively to FIGS. 1, 2, 3, 4 and 5.
1. Figure 11. Figure 1
Le mécanisme est au repos, car le doigt 27 du déclencheur 28 n'a pas encore attaqué le bras 24 de la deuxième bascule 21. Dans cet état, la dent 14 de la première bascule 11 immobilise la came 16 et la roue de bascule 15 est tenue éloignée de la roue 10. La dent 26 de la deuxième bascule 21 n'est pas en prise avec la came 16. L'aiguille 18 indique le quantième du jour.The mechanism is at rest, because the finger 27 of the trigger 28 has not yet attacked the arm 24 of the second rocker 21. In this state, the tooth 14 of the first rocker 11 immobilizes the cam 16 and the rocker wheel 15 is kept away from the wheel 10. The tooth 26 of the second lever 21 is not engaged with the cam 16. The hand 18 indicates the date of the day.
2. Figure 22. Figure 2
Quelques instants avant minuit, le doigt 27 attaque le bras 24 de la deuxième bascule 21. Celle-ci se met alors à pivoter dans le sens anti-horaire, entraînant la première bascule 11 dont la dent 14 libère la came 16 et dont la roue 15 est mise en relation avec la roue 10.A few moments before midnight, the finger 27 attacks the arm 24 of the second rocker 21. The latter then begins to pivot counterclockwise, causing the first rocker 11 whose tooth 14 releases the cam 16 and whose wheel 15 is connected with the wheel 10.
La roue 15 commence donc à tourner dans le sens anti-horaire, entraînant dans le sens horaire la roue 17, la came 16 et l'aiguille indicatrice de quantième 18 qui quitte la position qu'elle occupait depuis 24 heures. 3. Figure 3The wheel 15 therefore begins to rotate anti-clockwise, driving the wheel 17, the cam 16 and the date indicator hand 18 clockwise, which leaves the position it has occupied for 24 hours. 3. Figure 3
Quelques instants plus tard, le doigt 27 est sur l'extrémité du bras 24. La deuxième bascule 21 atteint ainsi son point le plus haut en même temps que sa dent 26 se met très momentanément en prise avec la came 16 qui a très légèrement tourné. Le déclencheur 28 ayant poursuivi sa rotation, la bascule 21 se trouve ainsi libérée et son bras 24 échappe au doigt 27. L'aiguille 18 continue donc sa rotation.A few moments later, the finger 27 is on the end of the arm 24. The second rocker 21 thus reaches its highest point at the same time as its tooth 26 very momentarily engages the cam 16 which has very slightly turned . The trigger 28 having continued its rotation, the rocker 21 is thus released and its arm 24 escapes the finger 27. The needle 18 therefore continues its rotation.
4. Figure 44. Figure 4
Le mouvement se poursuit ainsi car la dent 14 n'est pas engagée avec la came 16, alors que la dent 26 flotte.The movement thus continues because the tooth 14 is not engaged with the cam 16, while the tooth 26 floats.
5. Figure 55. Figure 5
La progression de la came 16 et de l'aiguille 18 se poursuit, sous l'action de la roue de bascule 15, jusqu'au moment où la première bascule 11 pivote sous l'action de son ressort 19 dans le sens horaire car sa dent 14 engrène de nouveau avec la came.The progression of the cam 16 and the needle 18 continues, under the action of the rocker wheel 15, until the first rocker 11 pivots under the action of its spring 19 clockwise because its tooth 14 meshes again with the cam.
Ce pivotement a pour effet simultané de bloquer la came 16 et de désengager la roue de bascule 15 de la roue entraîneuse 10. L'aiguille 18 s'immobilise ainsi dans sa nouvelle position où elle indique le quantième du jour qui commence. Le mécanisme se retrouve dans sa position initiale correspondant à la figure 1. Un nouveau cycle reprendra, environ 24 heures plus tard, lorsque le doigt entraîneur 27 attaquera de nouveau la deuxième bascule 21.This pivoting has the simultaneous effect of blocking the cam 16 and disengaging the rocking wheel 15 from the driving wheel 10. The needle 18 thus comes to a stop in its new position where it indicates the date of the day which begins. The mechanism returns to its initial position corresponding to FIG. 1. A new cycle will resume, approximately 24 hours later, when the driving finger 27 again attacks the second lever 21.
Le mécanisme qui vient d'être décrit permet ainsi l'affichage du quantième.The mechanism which has just been described thus allows the display of the date.
On remarquera cependant - et il s'agit là de l'avantage essentiel de la présente invention - qu'il suffit, par exemple, de remplacer la came 16 par une came à sept dents 29, bien entendu de même diamètre, telle que représentée à la figure 6. Le mécanisme permet alors d'afficher les sept jours de la semaine.It will be noted however - and this is the essential advantage of the present invention - that it suffices, for example, to replace the cam 16 by a cam with seven teeth 29, of course of the same diameter, as shown in Figure 6. The mechanism then displays the seven days of the week.
Diverses autres cames, montrées sur la figure 6, peuvent être utilisées, comme, par exemple, une came à douze dents 30 qui permet de réaliser un affichage à heures sautantes. Dans ce cas, bien entendu, le mobile déclencheur 28 devra être entraîné à raison d'un tour par heure. Rien n'empêche alors, pour réaliser des effets d'affichage, que les dents de la came soient espacées de manière irrégulière, comme cela est illustré par les cames 31 et 32.Various other cams, shown in FIG. 6, can be used, such as, for example, a twelve-tooth cam 30 which makes it possible to produce a jumping hour display. In this case, of course, the trigger mobile 28 will have to be driven at the rate of one revolution per hour. Nothing prevents then, to achieve display effects, that the teeth of the cam are spaced irregularly, as illustrated by cams 31 and 32.
Enfin, et sans que l'énumération des possibilités offertes par l'invention soit limitative, une came à soixante dents 33, associée à un mobile déclencheur 28 faisant un tour par heure, fournit un affichage à minutes sautantes.Finally, and without the list of possibilities offered by the invention being limiting, a sixty-tooth cam 33, associated with a trigger mobile 28 making one revolution per hour, provides a display with jumping minutes.
Bien entendu, la présente invention n'est pas limitée au cas d'un affichage par aiguille. Il est, en effet, aisé d'imaginer que la roue 17, au lieu de porter l'aiguille 18, pourrait aussi entraîner, grâce à un engrenage approprié, tout autre organe de fonction ou d'affichage, tel qu'un disque indicateur de quantième.Of course, the present invention is not limited to the case of a needle display. It is, in fact, easy to imagine that the wheel 17, instead of carrying the needle 18, could also cause, by means of an appropriate gear, any other function or display member, such as an indicator disc. date.
La présente description a été faite en se référant à une roue entraîneuse 10 tournant en permanence sous l'action d'un barillet. Il va de soi, cependant, que cette roue pourrait est entraînée de manière discontinue, juste pendant le temps nécessaire pour réaliser la fonction d'affichage demandée. Il va de soi, également, que cette roue pourrait être entraînée par un moteur électrique.The present description has been made with reference to a driving wheel 10 rotating continuously under the action of a barrel. It goes without saying, however, that this wheel could be driven discontinuously, just for the time necessary to perform the requested display function. It goes without saying, also, that this wheel could be driven by an electric motor.
Ainsi est proposé un mécanisme offrant au constructeur horloger un large spectre de possibilités d'affichage des fonctions du temps, sans qu'il soit nécessaire de procéder à de lourdes adaptations. Thus, a mechanism is proposed offering the watchmaker a wide spectrum of possibilities for displaying time functions, without the need for heavy adaptations.
