Description
Pièce d'horlogerie à calendrier0
La présente invention a pour objet une pièce d'horlogerie à calendrier.
On connait des pièces d'horlogerie dans lesquelles la lecture de l'heure s'effectue à l'aide d'un miroir ou d'un prisme; la présente invention constitue une application de ce principe.
La pièce d'horlogerie suivant la présente in vention est caractérisée par le fait qu'au moins un indicateur du calendrier, notamment celui des quantièmes, comprend des indications portées a l'envers sur une surface péripherique tronconique, ces indications apparaissant, par reflexion, sur une surface annulaire formant miroir, également tronconique, coaxiale à la première.
Le dessin représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention.
La fig. 1 est une vue en plan d'une montrebracelet, avec partie arrachée, et,
La fig. 2 est une coupe d'un détail, à échelle agrandie, suivant la ligne Il-Il de la fig. 1.
La montre-bracelet représentée comprend un mouvement 1 logé à l'intérieur d'une boîte formée d'une carrure-lunette 2, d'une glace j et d'un fond 4. Le mouvement comprend une couronne rotative 5 présentant une surface périphérique tronconique 6 sur laquelle est inscrite l'indication des quantièmes. Un mécanisme entraînant pas à pas la couronne 5, à raison d'un pas par vingt-quatre heures, n'a pas été représenté, étant étranger à la présente invention.
Le cadran, désigné par 7, présente une partie périphérique bombée 7a, recouvrant la surface tronconique 6 de la couronne 5. Une encoche 8, formant guicllet, est ménagée daiis ladite partie périphérique 7a du cadran.
La carrure-lunette 2 presente une surface intérieure 9, tronconique, polie de manière a former un miroir dans lequel les indications des quantièmes sont visibles a travers le guichet 8; is quantièmes, désignés par 10, dont un petit nombre seulement a ét représenté, sont portes à l'envers sur la surface 6 de nianière à apparaître, par réflexion, à l'endroit sur la surface 9.
Les génératrices des deux surfaces 6 et 9, dans un plan radial correspondallt, par exemple, au plan de la coupe
II-II, forment entre elles un angle α de 900.
Le porteur de la montre n'observant celle-ci que rarement tout à fait en plan, l'encoche 8 a été ménagée dans le cadran > à 12 heures, de orte que ladite encoche est peu apparente. Le chiffre des quantièmes est caché, sur la couronne j, par la partie 7b du cadran, tandis qu'au contraire il apparatt parfaitement dans le miroir 9.
En variante, le miroir 9 pourra être ménagé sur une bague forcée dans le corps de bofte, comme repré- senté en 11, en traits mixtes, dans la fig. 2. I1 pourra également entre ménagé sur un épaississement périphérique du cadran, ce dernier étant alors réalisé, de préférence, en matière plastique.
Le cadran pourra également être muni d'une loupe occupant l'espace laissé libre par l'encoche 8.

Calendar timepiece0
The present invention relates to a timepiece with a calendar.
We know of timepieces in which the time is read using a mirror or a prism; the present invention constitutes an application of this principle.
The timepiece according to the present invention is characterized by the fact that at least one calendar indicator, in particular that of the dates, comprises indications carried upside down on a frustoconical peripheral surface, these indications appearing, by reflection, on an annular surface forming a mirror, also frustoconical, coaxial with the first.
The drawing represents, by way of example, an embodiment of the object of the invention.
Fig. 1 is a plan view of a wristwatch, with part broken away, and,
Fig. 2 is a section of a detail, on an enlarged scale, along the line II-II of FIG. 1.
The wristwatch shown comprises a movement 1 housed inside a case formed by a caseband-bezel 2, a crystal j and a back 4. The movement comprises a rotating crown 5 having a peripheral surface. frustoconical 6 on which is written the indication of the dates. A mechanism driving crown 5 step by step, at a rate of one step per twenty-four hours, has not been shown, being foreign to the present invention.
The dial, designated by 7, has a curved peripheral part 7a, covering the frustoconical surface 6 of the crown 5. A notch 8, forming a guicllet, is made in said peripheral part 7a of the dial.
The middle-bezel 2 has an inner surface 9, frustoconical, polished so as to form a mirror in which the date indications are visible through the aperture 8; is dates, designated by 10, of which only a small number has been shown, are worn upside down on the nianière surface 6 to appear, by reflection, upside down on the surface 9.
The generatrices of the two surfaces 6 and 9, in a radial plane correspond, for example, to the plane of the section
II-II, form between them an angle α from 900.
As the wearer of the watch rarely observes it completely in plane, the notch 8 has been made in the dial> at 12 o'clock, so that said notch is not very visible. The date number is hidden, on crown j, by part 7b of the dial, while on the contrary it appears perfectly in mirror 9.
As a variant, the mirror 9 could be provided on a forced ring in the box body, as shown at 11, in phantom lines, in FIG. 2. It may also be formed on a peripheral thickening of the dial, the latter then being preferably made of plastic.
The dial may also be fitted with a magnifying glass occupying the space left free by notch 8.
R E V E N I) I C A T I O N
calendar timepiece, characterized by the fact that at least one calendar indicator, in particular that of the dates, comprises indications carried backwards on a frustoconical peripheral surface, these indications appearing, by reflection, on an annular surface forming mirror, also tronconi que, coaxial with the first.
