Description

La présente invention se rapporte aux mécanismes de quantièmes du type à grand guichet facilitant la lecture de la date.The present invention relates to date mechanisms of the type with a large window facilitating the reading of the date.

Un tel mécanisme est décrit dans le document WO98/50829 . Il comporte un mobile de commande annulaire effectuant un tour par mois, à raison de trente et un pas et muni de deux dentures entraînant respectivement un mobile d'affichage des unités et un mobile d'affichage des dizaines du quantième. Les mobiles d'affichage sont coplanaires et disposés côte à côte à l'intérieur de l'anneau formé par le mobile de commande. Le fait que les mobiles d'affichage soient coplanaire limite leur diamètre, pour un diamètre donné du calibre équipé du mécanisme de quantième, ce qui entraîne une diminution de la grandeur des chiffres portés par ces mobiles d'affichage et réduit donc la lisibilité de l'affichage du quantième. De plus, la réalisation du mobile de commande est délicate et compliquée du fait de ses trois dentures différentes.Such a mechanism is described in the document WO98 / 50829 . It comprises an annular control wheel performing one turn per month, thirty-one steps and provided with two sets of teeth respectively driving a mobile display units and a display mobile dozens of the date. The display mobiles are coplanar and arranged side by side inside the ring formed by the control mobile. The fact that the display mobiles are coplanar limits their diameter, for a given diameter of the caliber equipped with the date mechanism, which causes a decrease in the size of the figures carried by these display mobiles and therefore reduces the readability of the display. display of the date. In addition, the realization of the control wheel is delicate and complicated because of its three different teeth.

La demande de brevet européen publiée EP 1555585 décrit également un tel mécanisme comportant un mobile de commande sous forme d'une couronne effectuant un tour en un mois en trente et un pas journalier et comportant deux dentures. Une de ces dentures entraîne un mobile d'affichage des unités par un premier train d'engrenages et l'autre entraîne un mobile d'affichage des dizaines par un second train d'engrenages, les deux mobiles d'affichage étant concentriques. Ce mécanisme est complexe, couronne de commande à trois dentures, deux trains d'engrenages distincts et deux disques d'affichage superposés et concentriques. Un tel mécanisme est très encombrant et complexe.The published European patent application EP 1555585 also discloses such a mechanism comprising a control mobile in the form of a crown performing a lathe in one month in thirty-one steps daily and having two teeth. One of these teeth drives a mobile display of the units by a first gear and the other drives a display mobile dozens by a second gear, the two display mobiles being concentric. This mechanism is complex, three-toothed control crown, two separate gear trains and two superimposed and concentric display disks. Such a mechanism is very cumbersome and complex.

La demande de brevet publiée US 2006/0002237 décrit également un tel mécanisme comprenant une couronne motrice effectuant un tour en trente et un pas journalier munie de trois dentures différentes, un mobile d'affichage des unités comprenant une étoile de dix coopérant avec une denture de la couronne et portant un disque d'affichage des unités. Un mobile d'affichage des dizaines comporte une étoile des dizaines engrenant avec l'étoile des unités, et un disque des dizaines. Cette étoile de dizaine est en plus entraînée par une seconde denture de la couronne motrice par l'intermédiaire d'un pignon. Les deux disques d'affichage sont coplanaires et tangents l'un à l'autre. Ici également le diamètre des disques d'affichage est réduit, diminuant la dimension des chiffres qu'ils portent et donc la lisibilité. La couronne motrice comporte trois dentures et est donc complexe à réaliser.The published patent application US 2006/0002237 also discloses such a mechanism comprising a drive crown performing a lap in thirty-one daily steps provided with three different teeth, a mobile display units comprising a star of ten cooperating with a toothing of the crown and carrying a display disc units. A display mobile tens has a star tens meshing with the star of the units, and a tens disk. This star of ten is in addition driven by a second toothing of the driving ring by means of a pinion. The two display disks are coplanar and tangent to each other. Here also the diameter of the display disks is reduced, decreasing the size of the numbers they carry and therefore readability. The driving ring has three teeth and is therefore complex to achieve.

Le brevet CH 310559 décrit également un tel mécanisme de quantième comportant un mobile intermédiaire à trois planches entraîné à raison de trente et un pas par tour. La première planche de ce mobile intermédiaire comporte trente et une dents et sert à son entraînement; la seconde planche comporte trente dents et un espace vide et coopère avec l'étoile d'un mobile d'affichage des unités; la troisième planche comporte une denture de quatre dents et coopère avec l'étoile d'un mobile d'affichage des dizaines. Les deux mobiles d'affichage comportent des disques d'affichage coplanaires et tangents. Le diamètre de ces disques est donc limité et donc également la grandeur des chiffres qu'ils portent.The patent CH 310559 also describes such a date mechanism comprising an intermediate mobile three boards driven at a rate of thirty-one steps per turn. The first board of this intermediate mobile has thirty-one teeth and serves for its training; the second board has thirty teeth and an empty space and cooperates with the star of a mobile unit display; the third board has a toothing of four teeth and cooperates with the star of a tens display mobile. Both display mobiles have coplanar and tangent display disks. The diameter of these discs is therefore limited and therefore also the size of the numbers they carry.

La présente invention a pour but de réaliser un mécanisme de quantième du type à grand guichet facilitant la lecture de la date tendant à obvier aux inconvénients précités des réalisations antérieures. Notamment, un but est de faire en sorte que la couronne de quantième d'un mouvement existant puisse être utilisée comme organe moteur sans grande modifications, que la liaison cinématique entre cette couronne de quantième et les mobiles d'affichage se fasse aussi directement que possible et avec des mobiles à deux planches au maximum. Enfin, un autre but est encore de permettre un plus grand affichage de la date en faisant en sorte que le diamètre des disques d'affichage ne soit pas limité à 0,5 fois le diamètre du calibre équipé de ce mécanisme.The object of the present invention is to provide a date mechanism of the type with a large window facilitating the reading of the date tending to obviate the aforementioned drawbacks of the previous embodiments. In particular, one goal is to ensure that the date crown of an existing movement can be used as a motor without much modifications, that the kinematic connection between the calendar crown and the display mobiles is done as directly as possible and with mobiles to two boards maximum. Finally, another goal is to allow a larger display of the date by ensuring that the diameter of the display disks is not limited to 0.5 times the diameter of the caliber equipped with this mechanism.

La présente invention a pour objet un mécanisme de quantième caractérisé par le fait qu'il comporte en combinaison une couronne entraîneuse ou de quantième entraînée pas à pas et effectuant un tour complet en trente et un pas journaliers, cette couronne de quantième comportant uniformément réparties sur sa périphérie, trente goupilles et un espace vide, l'une desdites goupilles étant plus longue que les autres; un mobile d'affichage des unités du quantième comportant un disque des unités munis des chiffres 0 à 9 des unités du quantième et une étoile des unités de dix dents coopérant avec toutes les goupilles de la couronne de quantième; un mobile d'affichage des dizaines du quantième comportant un disque des dizaines munis des chiffres 0 à 3 des dizaines du quantième et une étoile des dizaines coopérant avec la seule goupille longue de la couronne de quantième; un mobile intermédiaire comprenant d'une part une roue de trente dents en prise avec l'étoile des unités et d'autre part une étoile intermédiaire de trois dents coopérant avec l'étoile des dizaines et par le fait que le disque des unités chevauche partiellement le disque des dizaines de sorte que pour chaque position stable de ces disques un chiffre du disque des dizaines soit aligné sur et jouxte un chiffre du disque des unités affichant ainsi le nombre de 1 à 31 représentant un quantième donné.The present invention relates to a date mechanism characterized in that it comprises in combination a driving crown or date driven step by step and performing a complete turn in thirty-one steps daily, this date crown having uniformly distributed on its periphery, thirty pins and an empty space, one of said pins being longer than the others; a display unit of the date units comprising a disk units with numbers 0 to 9 of the date units and a star of the units of ten teeth cooperating with all the pins of the date ring; a mobile display tens of the date having a tens disk equipped with digits 0 to 3 tens of the date and a star of the tens co-operating with the single long pin of the date ring; an intermediate mobile comprising on the one hand a wheel of thirty teeth in engagement with the star of the units and on the other hand an intermediate star of three teeth cooperating with the star of tens and in that the disk of the units partially overlaps the tens disk so that for each stable position of these disks a digit of the tens disk is aligned on and adjoins a disk number of the units thus displaying the number from 1 to 31 representing a given date.

Les figures 1 et 2 du dessin annexé illustrent un mouvement horloger de base ou calibre équipé d'un quantième à grand guichet selon l'invention. Le mécanisme de quantième à grand guichet utilise comme organe moteur la couronne de quantième 1 du mouvement horloger entraînée par sa denture interne comportant trente et une dents 2 uniformément réparties sur sa périphérie interne à raison d'un pas par jour. Cette couronne de quantième 1 effectue donc un tour complet en trente et un jours. L'entraînement de cette couronne de quantième 1 par le mouvement horloger s'effectue de manière classique.The Figures 1 and 2 of the appended drawing illustrate a basic watch movement or caliber equipped with a calendar with a large window according to the invention. The date mechanism with a large aperture uses as a driving member the date ring 1 of the watch movement driven by its teeth. internal having thirty-one teeth 2 uniformly distributed on its inner periphery at a rate of one step per day. This crown of date 1 thus performs a complete turn in thirty-one days. The drive of this date ring 1 by the watch movement is carried out in a conventional manner.

Cette couronne de quantième 1 est munie à sa périphérie de trente goupilles 3 et d'un espace vide 4 répartis uniformément le long de cette périphérie, l'une 3a des trente goupilles 3 est plus longue que les autres. Ces trente goupilles 3, 3a sont disposées sur une même circonférence.This date ring 1 is provided at its periphery with thirty pins 3 and with a vacuum space 4 distributed uniformly along this periphery, one of the three pins 30a 3 is longer than the others. These thirty pins 3, 3a are arranged on the same circumference.

Cette couronne de quantième est très facile à réaliser car elle ne comporte qu'une denture interne 2 pour son entraînement et une seule rangée de goupilles chassées dans sa périphérie. L'espace vide 4 correspond à deux fois la distance séparant deux goupilles 3 voisines et donc à deux pas de la couronne de quantième 1. Cette couronne de quantième est pivotée sur le calibre de base de façon habituelle.This calendar crown is very easy to achieve because it has only internal teeth 2 for its drive and a single row of pins driven in its periphery. The empty space 4 corresponds to twice the distance separating two adjacent pins 3 and thus two steps from the date ring 1. This date ring is pivoted on the base gauge in the usual way.

Le mécanisme de quantième comporte encore un mobile des unités et un mobile des dizaines.The date mechanism also comprises a mobile units and a tens mobile.

Le mobile des unités comporte une étoile des unités 5 de dix dents et un disque des unités 6 portant sur sa surface supérieure les chiffres de 0 à 9 des unités du quantième uniformément répartis sur sa périphérie. Ces chiffres sont orientés sensiblement perpendiculairement à un rayon du disque des unités tangent à la partie supérieure du chiffre considéré. La circonférence du disque des unités présente des facettes 7 sensiblement parallèles à chacun des chiffres portés par ce disque des unités.The units mobile comprises a star of the units of ten teeth and a disk of the units 6 bearing on its upper surface the numbers from 0 to 9 of the calendar units uniformly distributed on its periphery. These figures are oriented substantially perpendicularly to a radius of the disk units tangent to the upper part of the figure. The circumference of the disk of the units has facets 7 substantially parallel to each of the figures carried by this disk of the units.

L'étoile de dix des unités 5 est située de telle façon que ses dents soient sur le chemin des goupilles 3, 3a lors de la rotation de la couronne de quantième 1. Ainsi, chaque jour du premier au trente et un d'un mois donné, l'étoile des unités 5 est entraînée d'un pas par une des goupilles 3, 3a. Lors du trente et unième pas de la couronne de quantième, l'espace vide 4 passe devant l'étoile des unités 5 et celle-ci n'est pas entraînée, le chiffre 1 reste dans le guichet 7 du cadran pendant deux pas successifs de la couronne de quantième 1. Un sautoir 8 coopérant avec la denture de l'étoile des unités 5 maintien le mobile des unités 5,6 dans une position angulaire stable entre deux actionnements par la couronne de quantième.The star of ten of the units 5 is located in such a way that its teeth are on the path of the pins 3, 3a during the rotation of the date ring 1. Thus, every day from the first to the thirty-one of a month given, the star of the units 5 is driven one step by one of the pins 3, 3a. During the thirty-first step of the date crown, the empty space 4 passes in front of the star of the units 5 and it is not driven, the number 1 remains in the window 7 of the dial during two successive steps of the date ring 1. A jumper 8 cooperating with the toothing of the star of the units 5 keeps the mobile units 5,6 in a stable angular position between two actuations by the date ring.

Le mobile des dizaines comporte une étoile des dizaines 9 de huit dents et un disque des dizaines 10 portant deux séries de chiffres de 0 à 3 répartis uniformément sur sa périphérie correspondant aux chiffres des dizaines de quantième. Dans l'exemple illustré, ces chiffres sont disposés suivant des directions parallèles à des diamètres du disque des dizaines 9. L'étoile des dizaines 9 comporte huit dents situées sur le chemin de la goupille 3a de plus grande longueur de la couronne de quantième 1. Ainsi, l'étoile des dizaines n'est entraînée par la couronne de quantième 1 qu'une fois par mois entre le trente et un et le premier du mois suivant, c'est-à-dire pendant le pas de la couronne de quantième 1 où l'étoile des unités 5 n'est pas entraînée. Il faut donc que l'angle compris entre deux droites passant par le centre de rotation de la couronne de quantième et les centres de rotation de l'étoile des unités 5 et l'étoile des dizaines 9 soit égal à l'angle entre deux rayons de la couronne de quantième passant l'un par la goupille 3a de grande longueur et l'autre par le centre de l'espace vide 4. Un sautoir 11 coopérant avec les dents de l'étoile des dizaines 9 maintien la position angulaire du mobile des dizaines 9,10 stable entre deux actionnements de celle-ci.The mobile tens comprises a star of tens 9 of eight teeth and a tens disk 10 carrying two sets of numbers from 0 to 3 distributed uniformly on its periphery corresponding to the numbers of tens of date. In the illustrated example, these figures are arranged in directions parallel to the diameters of the tens disk 9. The star of the tens 9 has eight teeth located on the path of the pin 3a of greater length of the date ring 1 Thus, the star of the tens is driven by the crown of date 1 only once a month between the thirty-first and the first of the following month, that is to say during the step of the crown of date 1 where the star of the units 5 is not driven. It is therefore necessary that the angle between two lines passing through the center of rotation of the date ring and the centers of rotation of the star of the units 5 and the star of the tens 9 be equal to the angle between two radii of the date ring passing one by the pin 3a of great length and the other by the center of the empty space 4. A jumper 11 cooperating with the teeth of the tens star 9 maintaining the angular position of the mobile tens 9.10 stable between two actuations thereof.

Le mécanisme de quantième comporte enfin un mobile intermédiaire comportant une première planche 12 de trente dents engrenant avec l'étoile des unités 5 et une seconde planche 13 de trois dents coopérant avec l'étoile des dizaines 9. De cette façon l'étoile des dizaines 9 du mobile des dizaines 9,10 est entraînée quatre fois par mois, trois fois par le mobile intermédiaire 12, 13 entre le neuf et le dix, le dix-neuf et le vingt et le vingt-neuf et le trente de chaque mois et une fois par la couronne de quantième entre le trente et un d'un mois et le premier du mois suivant.The date mechanism finally comprises an intermediate mobile having a first board 12 of thirty teeth meshing with the star of the units 5 and a second board 13 of three teeth cooperating with the star of the tens 9. In this way the star dozens 9 of the mobile tens 9,10 is driven four times a month, three times by the intermediate mobile 12, 13 between the nine and ten, the nineteen and twenty and twenty-nine and thirty of each month and once by the date crown between the thirty-one of a month and the first of the following month.

Ainsi, le principe du présent mécanisme de quantième est que la couronne entraîneuse ou couronne de quantième comportant trente goupilles entraîne seulement les unités du premier au trente et unième jours du mois. Les dizaines sont, elles, entraînées par un mobile intermédiaire comportant trente dents sur une première planche entraînée par l'étoile des unités et trois dents sur une seconde planche entraînant l'étoile des dizaines. Du trente et unième jour d'un mois au premier du mois suivant la couronne de quantième entraîne avec son unique goupille longue l'étoile des dizaines seulement.Thus, the principle of the present date mechanism is that the driving ring or crown date with thirty pins leads only units from the first to the thirty-first days of the month. The tens are, they, driven by an intermediate mobile with thirty teeth on a first board driven by the star of the units and three teeth on a second board driving the star tens. From the thirty-first day of a month to the first of the month following the date crown brings with it its single long pin the star of tens only.

Ce mécanisme de quantième présente beaucoup d'avantages. Le nombre de mobiles le composant, quatre mobiles dont trois de deux planches seulement. La couronne entraîneuse ou couronne de quantième 1 est simple puisqu'elle ne comporte qu'une denture intérieure classique pour son entraînement et une seule rangée de goupilles formant l'équivalent de deux dentures distinctes nécessaires dans les dispositifs antérieurs.This date mechanism has many advantages. The number of mobiles composing it, four mobiles of which three of two boards only. The driving ring or crown of date 1 is simple since it has a conventional internal toothing for its drive and a single row of pins forming the equivalent of two separate teeth necessary in the previous devices.

Le mobile intermédiaire ne comporte que deux planches et non pas trois comme souvent dans l'art antérieur.The intermediate mobile has only two boards and not three as often in the prior art.

De plus, du fait que les disques des unités et des dizaines se chevauchent partiellement, leur diamètre peut être plus grand et donc les chiffres qu'ils portent peuvent être plus grand et donc plus lisibles pour un diamètre donné du calibre.In addition, because the disks of the units and tens overlap partially, their diameter may be larger and therefore the numbers they carry may be larger and therefore more readable for a given diameter of the caliber.

Enfin, si le calibre de base le permet, la mise à l'heure ou au jour peut se faire dans un sens ou dans l'autre indifféremment, le fonctionnement du mécanisme de quantième décrit étant réversible.Finally, if the basic caliber allows it, setting the time or day can be done in one direction or the other indifferently, the operation of the date mechanism described being reversible.

Dans l'exemple illustré, le guichet 7 du cadran est situé entre 10H et 11 H mais ceci n'est pas limitatif. D'autres emplacements pour l'affichage du quantième peuvent être choisis ce qui peut entraîner une modification du positionnement des chiffres sur les disques d'affichage et de la distance d'arc séparant la goupille longue 3a de l'espace vide 4 de la couronne de quantième 1 de même que la distance d'arc entre les axes des mobiles d'affichage, ainsi que le diamètre des planches du mobile intermédiaire 12, 13.In the example illustrated, the window 7 of the dial is located between 10H and 11H but this is not limiting. Other locations for the display of the date can be chosen which can cause a change in the positioning of the numbers on the display discs and the arc distance between the long pin 3a of the empty space 4 of the crown of date 1 as well as the arc distance between the axes of the display mobiles, as well as the diameter of the boards of the intermediate mobile 12, 13.

Dans une variante, le disque des dizaines pourrait être situé partiellement au-dessus du disque des unités, mais toujours ces deux disques se chevauchant partiellement permettant d'avoir des disques d'un diamètre supérieur à 0,5 fois le diamètre du calibre, ménageant ainsi plus de place pour les chiffres portés par ce disque.In one variant, the tens disk could be located partially above the disk of the units, but still these two disks overlap partially allowing to have disks with a diameter greater than 0.5 times the diameter of the caliber, thus saving more space for the figures carried by this disk.
