B. Etat de la techniqueB. State of the art
Les mécanismes d'affichage du quantième de grand format réalisés jusqu'à aujourd'hui sont très complexes, volumineux, par conséquent très difficiles à réaliser en raison de ladite complexité et du grand nombre de pièces utiles, de sorte que les coûts de production de tels mécanismes sont extrêmement lourds.The large format date display mechanisms produced to date are very complex, bulky, and therefore very difficult to produce due to the said complexity and the large number of useful parts, so that the production costs of such mechanisms are extremely cumbersome.
Les conséquences directes de ce qui précède sont les difficultés de montage sur des mouvements existants ainsi que l'augmentation de volume consécutive desdits mouvements ce qui nuit souvent à l'aspect esthétique des montres et empêche la commercialisation de ces montres à des coûts abordables.The direct consequences of the above are the difficulties of mounting on existing movements as well as the consecutive increase in volume of said movements which often harms the aesthetic appearance of watches and prevents the marketing of these watches at affordable costs.
La plupart des systèmes existants sont limités par la taille réduite des chiffres d'indication de la date et doivent être équipés de loupes permettant une lecture plus aisée. C. Description techniqueMost of the existing systems are limited by the reduced size of the date indication digits and must be equipped with magnifiers for easier reading. C. Technical description
Le dessin annexé illustre schematiquement en une vue éclatée le mécanisme d'affichage grand format du quantième qui compte trois mobiles.The appended drawing schematically illustrates in an exploded view the large format date display mechanism which has three mobiles.

- Plan E : cadran de la montre percé de deux guichets de grand format- Plan E: watch face pierced by two large format windows
1 . Description du plan A :1. Description of plan A:
Il s'agit d'un mouvement de montre ordinaire comportant une indication de quantième traditionnelle par couronne qui ne nécessite pas de remarques particulières.It is an ordinary watch movement with a traditional date indication by crown which does not require any particular remarks.
2. Description du plan B :2. Description of plan B:
Le mécanisme comporte tout d'abord une couronne programmée 1 destinée soit à remplacer la couronne d'origine du quantième, soit à être fixée sur cette couronne d'origine 2.The mechanism firstly comprises a programmed crown 1 intended either to replace the original date crown, or to be fixed to this original crown 2.
Cette couronne programmée comporte deux dentures représentant chacune un chemin et composés toutes deux de 31 dents, de longueur, de hauteur et de taille variables.This programmed crown has two teeth each representing a path and both composed of 31 teeth, of variable length, height and size.
Une chaîne cinématique entraîne cette couronne à raison d'un pas par jour à partir de la roue des heures du mouvement de la montre (plan A) pour effectuer une rotation complète en 31 jours.A kinematic chain drives this crown at the rate of one step per day from the hour wheel of the watch movement (plane A) to complete a rotation in 31 days.
Cet entraînement est discontinu et le pas s'effectue aux alentours de minuit chaque jour.This training is discontinuous and the step takes place around midnight each day.
Cette couronne programmée 1 pourrait également être entraînée par un moteur pas à pas (mouvement quartz) et un engrenage entraîné par ce moteur, moteur piloté par un garde temps électronique du mouvement. La couronne dentée programmée comporte une denture interne 3 de 31 dents formant le chemin d'entraînement des unités et une denture interne 4 de 31 dents également formant le chemin d'entraînement des dizaines de l'affichage du quantième.This programmed crown 1 could also be driven by a stepping motor (quartz movement) and a gear driven by this motor, motor controlled by an electronic movement timepiece. The programmed toothed crown has an internal toothing 3 of 31 teeth forming the drive path of the units and an internal toothing 4 of 31 teeth also forming the drive path of the tens of the date display.
Seules 30 des 31 dents de la denture interne 3 sont actives sur le chemin des unités, le système restant ainsi bloqué pendant deux jours lors de l'affichage des jours 31 d'un mois et 1 er du mois suivant, ceci en raison de l'inactivité de la 31 ème dent.Only 30 of the 31 teeth of internal teeth 3 are active on the way to the units, the system thus remaining blocked for two days when displaying days 31 of a month and 1 st of the following month, this due to the of the 31st tooth.
Sur les 31 dents de la denture 4, seuls 4 dents sont actives afin de programmer le chemin des dizaines lesquelles seront bloquées pendant 10 jours consécutifs (première dizaine, deuxième dizaine, troisième dizaine).Out of the 31 teeth of toothing 4, only 4 teeth are active in order to program the tens path which will be blocked for 10 consecutive days (first ten, second ten, third ten).
Les dentures 3 et 4 peuvent se présenter dans un même plan auquel cas les dents formant le chemin des dizaines seront plus longues que celles de la denture formant le chemin des unités.The teeth 3 and 4 can be in the same plane in which case the teeth forming the tens path will be longer than those of the teeth forming the units path.
Les dentures 3 et 4 peuvent tout autant être décalées en hauteur de sorte que la denture formant le chemin des unités se trouve dans un plan plus élevé que la denture formant le chemin des dizaines.The teeth 3 and 4 can equally be offset in height so that the teeth forming the path of the units lie in a higher plane than the teeth forming the path of the tens.
3. Description du Plan C :3. Description of Plan C:
Le plan C est constitué d'une platine 5 entourant la couronne programmée et destinée à être fixée sur le mouvement de la montre (plan A).The plane C consists of a plate 5 surrounding the programmed crown and intended to be fixed to the movement of the watch (plane A).

Ce mécanisme comporte encore un mobile des unités ainsi qu'un mobile des dizaines.This mechanism also includes a mobile unit and a mobile tens.
Le mobile des unités est composé d'une étoile des unités 7 de 10 dents solidaires, d'un disque d'affichage des unités 8 présentant sur sa surface supérieure des chiffres de 0 à 9 disposés tangentiellement et répartis uniformément le long de la périphérie de ce disque des unités 8.The unit mobile consists of a unit star 7 of 10 integral teeth, a unit display disc 8 having on its upper surface numbers from 0 to 9 tangentially arranged and distributed uniformly along the periphery of this drive units 8.
Ce mobile des unités 7, 8 pivote sur la platine 5 et reste maintenu par une vis 9; il est positionné de telle sorte que les dents de l'étoile des unités 7 se trouvent au même niveau que le chemin formé par la denture interne 3 de la couronne programmée. Le mobile des dizaines est composé d'une étoile des dizaines 10 de 4, 8 ou 1 2 dents solidaires, d'un disque d'affichage des dizaines 1 1 présentant sur sa surface supérieure des chiffres de 0 à 3 ( une, deux ou trois séries de chiffres) disposés tangentiellement et répartis uniformément le long de la périphérie de ce disque des dizaines 1 1 .This mobile unit 7, 8 pivots on the plate 5 and remains held by a screw 9; it is positioned so that the teeth of the star of the units 7 are at the same level as the path formed by the internal toothing 3 of the programmed crown. The tens mobile is made up of a tens star 10 of 4, 8 or 1 2 integral teeth, a tens display disc 1 1 having on its upper surface numbers from 0 to 3 (one, two or three sets of numbers) arranged tangentially and evenly distributed along the periphery of this tens tens 1 1 disc.
Ce mobile des dizaines 1 1 pivote sur la platine 5 et est maintenu par une vis axiale 1 2; il est positionné de telle sorte que les dents de l'étoile des dizaines 10 se trouvent au même niveau que le chemin formé par la denture interne 4 de la couronne programmée.This tens 1 1 mobile pivots on the plate 5 and is held by an axial screw 1 2; it is positioned so that the teeth of the tens star 10 are at the same level as the path formed by the internal toothing 4 of the programmed crown.
Un ressort à deux branches 1 3 est fixé sur la platine 5 par une vis axiale 14 et chacune des ces branches constitue un sautoir entrant en contact avec les étoiles 7 et 10 pour bloquer leurs parties angulaires entre deux actionnements successifs.A spring with two branches 1 3 is fixed on the plate 5 by an axial screw 14 and each of these branches constitutes a jumper coming into contact with the stars 7 and 10 to block their angular parts between two successive actuations.
Les deux mobiles constitués respectivement des étoile crantée 7, du disque d'affichage 8 ainsi que de la vis axiale 9, pour l'un, et des étoile crantée 10, du disque d'affichage 1 1 ainsi que de la vis axiale 1 2, pour l'autre, sont totalement indépendants l' un de l'autre.The two mobiles respectively made up of star teeth 7, of the display disc 8 as well as of the axial screw 9, for one, and of star teeth 10, of the display disc 1 1 as well as of the axial screw 1 2 , for the other, are completely independent of each other.
5. Description du plan E :5. Description of plan E:
Le mécanisme est muni d'un cadrant 1 5 percé d'un grand guichet 1 6 à 2 fenêtres d'une dimension, en principe minimum de 2 x 4 mm, cadran qui recouvre tout le mécanisme et se fixe à l'aide de pieds 1 7 (au nombre de 4) sur la platine 5.The mechanism is provided with a dial 1 5 pierced with a large window 1 6 with 2 windows of a dimension, in principle a minimum of 2 × 4 mm, dial which covers the entire mechanism and is fixed using feet. 1 7 (4 in number) on deck 5.
D. FonctionnementD. Operation
Par l'engrainement de l'étoile des unités 7 avec les 30 dents actives de la denture des unités 3 de la couronne de quantième 1 , le disque d'affichage des unités avance d'un pas par jour et effectue un tour complet en 10 jours annotant ainsi pour chaque jour le chiffre des unités correspondant au quantième dans le guichet 1 6 du cadran 1 5 sauf s'il s'agit de la troisième révolution qui s'effectue en 1 1 jours, le chemin programmé par la denture 3 laissant inactive une dent lorsque l'unité 1 passe du 31 ème jour d'un mois au premier jour du mois suivant.By training the star of the units 7 with the 30 active teeth of the teeth of the units 3 of the date crown 1, the display disc of the units advances one step per day and performs a complete revolution in 10 days thus annotating for each day the number of units corresponding to the date in the window 1 6 of the dial 1 5 unless it is the third revolution which takes place in 1 1 days, the path programmed by the toothing 3 leaving inactivates a tooth when unit 1 goes from the 31st day of a month to the first day of the following month.
Par l'engrainement de l'étoile des dizaines 10 avec la denture des dizaines 4 de la couronne programmée, le disque des dizaines 1 1 avance d'un, de deux ou de trois pas tous les dix jours de manière à ce que le chiffre correspondant aux dizaines du quantième apparaisse dans le guichet 1 6 du cadran 1 5. En fonction du nombre de dents de l'étoile 10 et de la denture des dizaines 4, le disque des dizaines 1 1 effectue une révolution en 1 , 2 ou 3 mois.By training the tens 10 star with the teeth of the tens 4 of the programmed crown, the tens 1 1 disc advances by one, two or three steps every ten days so that the number corresponding to the tens of the date appears in the window 1 6 of the dial 1 5. Depending on the number of teeth of the star 10 and the teeth of the tens 4, the tens disc 1 1 performs a revolution in 1, 2 or 3 months.
E. Disposition des disques d'affichageE. Arrangement of display discs
Ce mécanisme permet de disposer le grand guichet 16 du cadran 1 5 en de nombreux points de la surface de cadran 15 pour autant que les deux disques d'affichage soient fixées symétriquement de chaque côté d'un axe de sorte que les dizaines et les unités se rejoignent et soient affichées respectivement à gauche et à droite du point de tangente.This mechanism makes it possible to have the large window 16 of the dial 1 5 at numerous points on the dial surface 15 provided that the two display discs are fixed symmetrically on each side of an axis so that the tens and the units meet and are displayed respectively to the left and to the right of the tangent point.
La possibilité d'implantation topologique du mécanisme, objet de cette invention, permet une variation de disposition du guichet allant sur un angle ouvert entre 1 1 H et 1 H sur le haut du cadran et sur un angle ouvert entre 5H et 7H sur le bas du cadran.The possibility of topological implantation of the mechanism, object of this invention, allows a variation of arrangement of the window going on an open angle between 1 1 H and 1 H on the top of the dial and on an open angle between 5H and 7H on the bottom of the dial.
F. Avantage du mécanismeF. Advantage of the mechanism
Le mécanisme comporte un nombre très restreint de pièces et seulement trois mobiles (deux mobiles sur le plan D et un mobile sur le plan B). Il peut être entièrement assemblé et prémontré sur la platine 5 à l'exception de la couronne programmée 1 qui, elle, se place sur le mouvement.The mechanism has a very limited number of parts and only three mobiles (two mobiles on the D plane and one mobile on the B plane). It can be fully assembled and pre-shown on the plate 5 with the exception of the programmed crown 1 which is placed on the movement.
Une fois fixée sur le mouvement, la platine est ensuite équipée du cadran qui permettra l'affichage du quantième grand format.Once fixed to the movement, the plate is then equipped with the dial which will allow the display of the large date calendar.
Le guichet 16 est d'une dimension 2 fois supérieure à celle d'un guichet habituel.The window 16 is twice as large as that of a conventional window.
En outre, le volume du mécanisme est très faible ce qui permet une adaptation sur tous les mouvements actuellement existants prévoyant l'affichage du quantième.In addition, the volume of the mechanism is very low, which allows adaptation to all currently existing movements providing for the display of the date.
Ce mécanisme est remarquable par sa simplicité, son nombre restreint de pièces, sa fiabilité, et le faible coût de sa fabrication.This mechanism is remarkable for its simplicity, its limited number of parts, its reliability, and the low cost of its manufacture.
En outre, il est évident que cette invention a pour but de fabriquer et de produire un mouvement de montres ou de pendulettes muni d'un mécanisme d'affichage du quantième grand format tel que décrit ci-dessus. In addition, it is obvious that this invention aims to manufacture and produce a movement of watches or clocks provided with a large format date display mechanism as described above.
