Description
Dispositif d'entraînement d'un organe indicateur dans un mécanisme d'horlogerie
Las montres calendrier ,possèdent généralement outre
l'indication du quantième, celle des jours de la semaine.
Le mécanisme indiquant les jours de la semaine est genéralement composé d'un disque imprimé, monté sur
une roue à étoile à sept branches qui est mise en mouvement de rotation par une goupille chassée perpendiculairement dans une roue située dans un plan inférieur et faisant un tour en vingt-quatre heures, ladite goupille venant agir entre dleux branches consécutives de la roue à étoile pour lui faire effectuer un septième de tour.
D'autre part, afin de rendre plus instantané le passage d'un jour à l'autre et aussi afin de maintenir le disque en position correcte malgré des secousses éventuelles, un sautoir agit entre deux branches consécutives de la roue à étoile.
L'implantation sur la platine du côté du cadran de tous les organes nécessaires au fonctionnement de la montre calendrier, tels que remontoir, mise à l'heure, minuterie, quantième, etc., empêche souvent de position- ner l'axe de la roue de commande de l'étoile des jours aussi près que voulu de ladite roue en étoile. On est ainsi amené à avoir une roue de commande plus grande en diamètre de façon que la goupille chassée perpendl- culairement puisse venir coopérer avec les branches de la roue en étoile.
D'autre part, afin de permettre le passage de la roue de commande portant la goupille, il s'avère souvent né cessailre d'augmenter la hauteur finale du mouvntent, ce qui nuit à l'esthétique de la montre.
Pour remédier à ces inconvénients, on se propose de fournir un dispositif permettant d'entraîner un indicateur quelconque dans un mécanisme d'horlogerie, par exemple un indicateur dites jours, tout en facilitant l'implantation des diverses pièces et en apportant la possibilité d'une esthétique améliorée par la diminution de l'épais- seur finale de la montre.
A cet effet, l'invention concerne un dispositif d'en traînement d'un organe indicateur à denture circulaire
extérieure dans un mécanisme d'horlogerie, comprenant un organe de commande allongé et denté, dont une extrémité est guidée par un chemin de guidage coulissant, et qui est susceptible d'engrener périodiquement avec ladite denture sous l'action d'un organe excentrique d'une roue de commande, caractérisé par le fait que ledit organe excentrique entrains l'extrémlté opposée au guidage dudit organe dle commande, et par le fait que l'organe de comnaande est disposé d'une façon approximativement tangentielle à ladite denture.
On se réfère à la description suivante faite à titre d'exemple non limitatif et au dessin annexé dans leq,uel:
La fig. unique est une vue en plan du dispositif selon l'invention.
Le disque 1 sur lequel sont imprimés les jours de la semaine 2 est solidaire d'une roue à étoile 3 à sept bran- ches, respectivement, 4, 5, 6, 7, 8, 9, 10, qui pivote autour de l'axe 11.
La roue à étoile est maintenue en position par l'inter- médiailre d'un sautoir 12 pivotant autour de l'axe 13 et agissant entre les branches 9 et 10 par un ressort 14.
La mise en rotation de la roue 3 est réalisée par l'in termédiaire d'un rouage dem'uitiplioeÉeur comprenant la roue des heures 15, d'axe 11, le renvoi double 16 d'axe 17, la roue de commande 18 d'axe 19, laquelle porte un plot excentré 20. L'organe exoentrique constitué par ce plot 20 coopère avec un trou d'un organe de oom- mande constitué par une plaquette 21 pour animer celle-ci par rapport à un plot 22 agissant dans un chemin de guidage constitué par une ouverture allongée 23, d'un mouvement combiné de translation et de rotation, afin de permettre aux dents 24 et 25 de ladite plaquette 21 d'agir sur les branches respectivement 5 et 6 de la roue en étole et la faire tourner d'un septième de tour.
Le dispositif décrit permet de faire tourner le disque des jours 1 dans les deux sens. Dans des variantes de réalisation de l'invention, la plaquette 21 peut être mo difiée comme suit:
- L'ouverture 23 pourrait. être ouverte à une de ses extrémités, la plaqueue 21 se présentant sous la forme d'une fourchette;
- la plaquette 21 pourrait posséder, à la place de l'ouverture 23, une languette qui glisserait entre deux butées;
- la plaquette 21 pourrait être en deux ou plusieurs parties articulées, avec ou sans ressort.
Device for driving an indicator member in a clockwork mechanism
The calendar watches generally have in addition
the date indication, that of the days of the week.
The mechanism indicating the days of the week is generally composed of a printed disc, mounted on
a star wheel with seven branches which is set in a rotational movement by a pin driven perpendicularly in a wheel located in a lower plane and making one revolution in twenty-four hours, said pin acting between two consecutive branches of the star wheel to make him do a seventh turn.
On the other hand, in order to make the change from one day to another more instantaneous and also in order to keep the disc in the correct position despite any jerks, a jumper acts between two consecutive branches of the star wheel.
The implantation on the plate on the dial side of all the components necessary for the operation of the calendar watch, such as the winder, time setting, minute minder, date, etc., often prevents positioning of the axis of the watch. day star control wheel as close to said star wheel as desired. It is thus necessary to have a control wheel larger in diameter so that the pin driven out perpendicularly can cooperate with the branches of the star wheel.
On the other hand, in order to allow the passage of the control wheel carrying the pin, it often turns out to be necessary to increase the final height of the movement, which is detrimental to the aesthetics of the watch.
To remedy these drawbacks, it is proposed to provide a device making it possible to drive any indicator in a clockwork mechanism, for example a so-called day indicator, while facilitating the installation of the various parts and providing the possibility of aesthetics improved by reducing the final thickness of the watch.
To this end, the invention relates to a device for dragging an indicator member with circular teeth.
external in a clockwork mechanism, comprising an elongated and toothed control member, one end of which is guided by a sliding guide path, and which is capable of periodically meshing with said toothing under the action of an eccentric member d 'a control wheel, characterized in that said eccentric member drives the end opposite to the guiding of said control member, and in that the control member is disposed approximately tangentially to said toothing.
Reference is made to the following description given by way of non-limiting example and to the appended drawing in leq, uel:
Fig. single is a plan view of the device according to the invention.
The disc 1 on which the days of week 2 are printed is attached to a star wheel 3 with seven branches, respectively, 4, 5, 6, 7, 8, 9, 10, which pivots around the axis 11.
The star wheel is held in position by the intermediary of a jumper 12 pivoting about the axis 13 and acting between the branches 9 and 10 by a spring 14.
The rotation of the wheel 3 is carried out by means of a dem'uitiplioeeur gear comprising the hour wheel 15, of axis 11, the double return 16 of axis 17, the control wheel 18 of axis 19, which carries an eccentric stud 20. The exoentric member constituted by this stud 20 cooperates with a hole of a control member constituted by a plate 21 to animate the latter with respect to a stud 22 acting in a guide path formed by an elongated opening 23, of a combined translational and rotational movement, in order to allow the teeth 24 and 25 of said plate 21 to act on the branches 5 and 6 respectively of the stole wheel and the rotate a seventh of a turn.
The device described makes it possible to rotate the day disc 1 in both directions. In variant embodiments of the invention, the wafer 21 can be modified as follows:
- Opening 23 could. be open at one of its ends, the plaqueue 21 being in the form of a fork;
- The plate 21 could have, instead of the opening 23, a tab which would slide between two stops;
- The plate 21 could be in two or more articulated parts, with or without a spring.
