I. DESCRIPTIONI. DESCRIPTION
A. IntroductionA. Introduction
La présente invention a pour but la réalisation d'un mécanisme d'affichage du quantième de grand format pour tous mouvements d'horlogerie, en particulier de montres et de pendulettes, permettant une lecture aisée de la date, dont la construction est simple puisqu'elle nécessite et combine un nombre réduit de pièces et de mobiles.The object of the present invention is to provide a large format date display mechanism for all watch movements, in particular watches and clocks, allowing easy reading of the date, the construction of which is simple since it requires and combines a reduced number of parts and mobiles.
Cette invention a également pour but de diminuer le volume (notamment par réduction de la hauteur) du mécanisme sus-décrit et le rendre, une fois les mobiles préassemblés aisément adaptable à tous les mouvements de montres existants comportant une indication de quantième traditionnelle par couronne, dès lors que ce mécanisme peut être entraîné par la couronne de quantième du mouvement de la montre concernée qui sera modifiée en conséquence.This invention also aims to reduce the volume (in particular by reducing the height) of the above-described mechanism and make it, once the preassembled mobiles easily adaptable to all existing watch movements comprising a traditional date indication by crown, since this mechanism can be driven by the date crown of the movement of the watch concerned which will be modified accordingly.
Cette invention a pour objet un mécanisme d'affichage grand format du quantième pour tous mouvements de montres et de pendulettes permettant d'atteindre le but sus-décrit et comportant les caractéristiques définies à la revendication 1 .The subject of this invention is a large format date display mechanism for all movements of watches and clocks making it possible to achieve the above-described aim and comprising the characteristics defined in claim 1.
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

4. Description du Plan D :4. Description of Plan D:
Ce mécanisme comporte un mobile des dizaines.This mechanism includes a dozen mobile.
Le mobile des dizaines est composé d'une étoile 8 à quatre branches ou dents , d'un disque échancré d'affichage des dizaines 9 présentant sur sa surface supérieure des chiffres de 0 à 3 disposés tangentiellement et répartis uniformément.The tens mobile is made up of a star 8 with four branches or teeth, a notched disc displaying the tens 9 having on its upper surface numbers from 0 to 3 arranged tangentially and uniformly distributed.
Ce mobile des dizaines 8/9 pivote sur la platine 5 et est maintenu par une vis axiale 10; il est positionné de telle sorte que les dents de l'étoile des dizaines 8 se trouvent au même niveau que le chemin formé par la denture 4 de la couronne programmée 1 , soit 1 /2.This tens 8/9 mobile pivots on the plate 5 and is held by an axial screw 10; it is positioned so that the teeth of the tens star 8 are at the same level as the path formed by the teeth 4 of the programmed crown 1, that is 1/2.
Un sautoir 1 1 est fixé sur la platine 5 par une vis axiale 12 et entre en contact avec les branches de l'étoile 8 situées au même niveau pour maintenir bloquées les parties angulaires entre deux actionnement successifs.A jumper 1 1 is fixed to the plate 5 by an axial screw 12 and comes into contact with the branches of the star 8 located at the same level to keep the angular parts locked between two successive actuations.

Le mobile des dizaines 8/9 est entièrement dépendant de la couronne programmée 1 , ou 1 /2. 5. Description du plan E :The tens 8/9 mobile is entirely dependent on the programmed crown 1, or 1/2. 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 dizaines 8 avec la denture 4 de la couronne programmée 1 , soit 1 /2, le disque des dizaines 9 avance d'un 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 à côté des chiffres des unités 3 disposés sur la couronne programmée 1 , soit 1 /2.By entraining the tens star 8 with the teeth 4 of the programmed crown 1, that is 1/2, the tens disc 9 advances by one step 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 next to the numbers of the units 3 arranged on the programmed crown 1, that is 1/2.
Le disque des dizaines effectue une rotation complète en un mois.The tens disc rotates completely in one month.
E. Disposition du disque d'affichageE. Display disc layout
Ce mécanisme permet de disposer le grand guichet 1 6 du cadran 1 5 en de nombreux points de la surface de cadran 1 5 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 arrange the large aperture 1 6 of the dial 1 5 at numerous points on the dial surface 1 5 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. 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.The window 16 is twice as large as that of a conventional window. 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.
