Description
Pièce d'horlogerie La présente invention a pour objet une pièce d'horlogerie. Cette pièce d'horlogerie est caractérisée par le fait que son cadran est main tenu en place, en son centre, sur le bâti du mouvement, par une pièce de fixation à pas de vis, cette pièce étant percée d'un trou cen tral pour le passage des organes indicateurs de l'heure.
Dans certaines pièces d'horlogerie munies de plusieurs cadrans, dont certains sont rota tifs, il est très difficile de fixer le cadran cen tral au moyen des pieds habituels.
Le but de la présente invention est de per mettre la fixation aisée du cadran, dans de telles pièces d'horlogerie.
Le dessin annexé représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention et une variante.
La fig. 1 est une coupe axiale d'une partie d'une pièce d'horlogerie ; et la fig. 2 est une coupe axiale d'un détail de la variante.
La montre représentée dans la fig. 1 com prend une couronne de quantièmes 1, entraî née par une roue de quantièmes non représen tée. La platine 2 du mouvement porte un pont supplémentaire 3 servant au pivotement d'un train d'engrenages 4, 5, 6 et 7, entraînant un cadran rotatif 8 qui tourne sur un épaulement 2a de la platine et porte un tour de 24 heures indiquant l'heure universelle. La roue 4 est entraînée par une roue 9 qui est forcée sur la roue à canon des heures 10.
Le pont supplémentaire 3 est surmonté d'un cadran fixe 11 percé d'un guichet 12 ren dant visible la couronne 1 des quantièmes. Ce cadran est maintenu en place en son centre par une vis 13 ,engagée dans un canon 14 chassé à la fois dans le pont 3 et partiellement dans le trou central du cadran 11. La tête 13a de la vis<B>13</B> recouvre l'extrémité du canon 14 et prend appui sur le cadran 11. Elle présente deux fentes 15 permettant de la faire tourner au moyen d'un tournevis. La vis 13 est percée d'un trou central 16 pour le passage des orga nes indicateurs de l'heure. Le cadran 11 est enfin empêché de tourner par des pieds lla s'engageant dans des trous du pont 3.
Dans la variante de la fig. 2, le cadran 17 est maintenu en place en son centre par un écrou 18 se vissant sur un canon 19 fixé à la platine 20.
Timepiece The present invention relates to a timepiece. This timepiece is characterized by the fact that its dial is hand held in place, at its center, on the frame of the movement, by a fixing part with a screw thread, this part being pierced with a central hole for the passage of the time indicating organs.
In certain timepieces fitted with several dials, some of which are rotating, it is very difficult to fix the central dial by means of the usual feet.
The aim of the present invention is to make it possible to easily fix the dial in such timepieces.
The appended drawing represents, by way of example, an embodiment of the object of the invention and a variant.
Fig. 1 is an axial section of part of a timepiece; and fig. 2 is an axial section of a detail of the variant.
The watch shown in FIG. 1 com takes a date crown 1, driven by a date wheel not shown. The plate 2 of the movement carries an additional bridge 3 serving for the pivoting of a gear train 4, 5, 6 and 7, driving a rotary dial 8 which turns on a shoulder 2a of the plate and carries a 24 hour turn indicating universal time. Wheel 4 is driven by a wheel 9 which is forced onto the 10 hour cannon wheel.
The additional bridge 3 is surmounted by a fixed dial 11 pierced with a window 12 making visible the crown 1 of the dates. This dial is held in place in its center by a screw 13, engaged in a barrel 14 driven both in the bridge 3 and partially in the central hole of the dial 11. The head 13a of the screw <B> 13 </ B > covers the end of the barrel 14 and rests on the dial 11. It has two slots 15 allowing it to be turned by means of a screwdriver. The screw 13 is pierced with a central hole 16 for the passage of the hour indicators. The dial 11 is finally prevented from turning by feet 11a engaging in holes in the bridge 3.
In the variant of FIG. 2, the dial 17 is held in place at its center by a nut 18 screwing onto a barrel 19 fixed to the plate 20.
