La présente invention a pour objet une montre-bracelet à lunette tournante, dans laquelle ladite lunette tournante est maintenue en place sur le corps de boîte par la lunette de glace qui présente une partie périphérique débordant sur ladite lunette tournante, et dans laquelle l'un des éléments - lunet- te tournante et corps de boîte - porte au moins un organe d'arrêt mobile, soumis à l'action d'un ressort de rappel, et qui forme sautoir, cet organe d'arrêt coopérant avec une denture que présente l'autre élément - corps de boîte et lunette tournante - de manière à assurer la stabilité des différentes positions angulaires de la lunette. The subject of the present invention is a wristwatch with rotating bezel, in which said rotating bezel is held in place on the body of the case by the glass bezel which has a peripheral part extending beyond said rotating bezel, and in which one elements - rotating bezel and case body - carries at least one movable stop member, subjected to the action of a return spring, and which forms jumper, this stop member cooperating with a toothing that has the other element - box body and rotating bezel - so as to ensure the stability of the different angular positions of the bezel.

De telles montres-bracelets sont connues en soi comme cela ressort, par exemple, de la demande de brevet suisse (mémoire exposé) No 1.954/69. Such wristwatches are known per se as is apparent, for example, from the Swiss patent application (brief) No. 1.954 / 69.

Le but de la présente invention est de fournir une construction particulièrement simple et facile à monter pour ce qui est du dispositif d'arrêt mobile, en l'occurrence le dispositif à sautoir déterminant la stabilité des différentes positions angulaires de la lunette tournante. Le problème posé consiste donc à réaliser un tel dispositif qui soit à la fois compact et apte à être assemblé à part pour être ensuite monté comme un tout sur la boîte de la montre. The object of the present invention is to provide a particularly simple and easy-to-assemble construction with regard to the mobile stop device, in this case the jumper device determining the stability of the different angular positions of the rotating bezel. The problem posed therefore consists in producing such a device which is both compact and able to be assembled separately in order to then be mounted as a whole on the watch case.

De surcroît, il s'agissait de réaliser une telle montre sans qu'elle présente, spécialement en raison de l'existence du dispositif d'arrêt, de surépaisseur par rapport à une boîte ordinaire. In addition, it was a question of making such a watch without it having, especially due to the existence of the stop device, an excess thickness compared to an ordinary case.

Ces buts sont atteints grâce aux moyens définis dans la revendication 1. These aims are achieved by the means defined in claim 1.

Le dessin représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention. The drawing represents, by way of example, an embodiment of the subject of the invention.

La fig. 1 est une coupe d'un détail d'une montre-bracelet à lunette tournante. Fig. 1 is a section of a detail of a wristwatch with rotating bezel.

La fig. 2 est une coupe suivant la ligne Il - Il de la fig. 1, et La fig. 3 est une vue en plan. avec coupe partielle. d'un détail. Fig. 2 is a section along the line Il - Il of FIG. 1, and Fig. 3 is a plan view. with partial cut. of a detail.

La boîte de la montre représentée comprend un corps de boîte I présentant une manchette la sur laquelle est engagée à cran une lunette de glace 2. Une garniture d'étanchéité 3 est interposée entre la lunette 2 et le corps de boîte 1. La glace, désignée par 4. est constituée par un verre minéral trempé engagé dans une feuillure 5 de la lunette 2. avec interposition d'une garniture d'étanchéité 6. The watch case shown comprises a box body I having a cuff on which is engaged a notch of glass 2. A sealing gasket 3 is interposed between the bezel 2 and the box body 1. The glass, designated by 4. is constituted by a toughened mineral glass engaged in a rebate 5 of the bezel 2. with the interposition of a seal 6.

La montre représentée comprend une lunette tournante 7 présentant, sur sa face supérieure. une noyure 8 dans laquelle est logée une couronne 9 portant une graduation. Cette lunette tournante pourra servir à différents usages. en particulier à calculer des durées dans le cas où la montre serait une montre de plongée sous-marine. par exemple. The watch shown comprises a rotating bezel 7 having, on its upper face. a recess 8 in which is housed a crown 9 carrying a graduation. This rotating bezel can be used for different purposes. in particular to calculate durations in the case where the watch is a scuba diving watch. for example.

La lunette tournante 7 est maintenue en place sur la fttce supérieure 10 du corps de boîte 1 par une partie périphél ique 2a de la lunette de glace 2 qui déborde sur elle. The rotating bezel 7 is held in place on the upper fttce 10 of the box body 1 by a peripheral part 2a of the lens 2 which projects beyond it.

La lunette tournante 7 est percée d'un passage radial 1 1 (fig. 2), ouvert en 12. de façon que sa paroi présente une certaine élasticité, dans lequel est engagée à force une douille 13 enfermant la jupe tubulaire 14a d'un doigt d'arrêt 14. Ce dernier est soumis à l'action d'un ressort de rappel 15. à boudin, logé dans la douille 13, et engagé dans la jupe 14a. celleci étant maintenue en place dans la douille 13 par un sertissage 1 3a de celle-ci. The rotating bezel 7 is pierced with a radial passage 1 1 (fig. 2), opened at 12. so that its wall has a certain elasticity, in which is engaged by force a socket 13 enclosing the tubular skirt 14a of a stop finger 14. The latter is subjected to the action of a return spring 15. with coil, housed in the sleeve 13, and engaged in the skirt 14a. this being held in place in the socket 13 by a crimping 1 3a thereof.

Il est à remarquer que le dispositif d'arrêt susmentionné constitue un tout, formé de la douille 13, du doigt d'arrêt 14 et du ressort 15, se montant sur la lunette 7 une fois assemblé. It should be noted that the abovementioned stop device constitutes a whole, formed by the sleeve 13, the stop finger 14 and the spring 15, being mounted on the bezel 7 once assembled.

Le corps de boîte 1 présente une denture à dent-de-loup lb avec laquelle coopère le doigt d'arrêt 14, sous l'effet du ressort 15, de telle sorte que la lunette 7 ne peut tourner que dans le sens de la flèche 16 (fig. 3). le doigt 14 fonctionnant alors à l'instar d'un cliquet et assurant en outre la stabilité des différentes positions angulaires de la lunette tournante 7. The box body 1 has a serration toothed wolf lb with which cooperates the stop finger 14, under the effect of the spring 15, so that the bezel 7 can only rotate in the direction of the arrow 16 (fig. 3). the finger 14 then operating like a ratchet and also ensuring the stability of the different angular positions of the rotating bezel 7.

En variante, la denture lb pourrait être symétrique. auquel cas la lunette 7 pourrait tourner dans les deux sens. le doigt 14 fonctionnant alors à l'instar d'un sautoir et assurant la stabilité des différentes positions de la lunette. Alternatively, the teeth lb could be symmetrical. in which case the telescope 7 could rotate in both directions. the finger 14 then operating like a jumper and ensuring the stability of the different positions of the telescope.

En variante également, on pourrait prévoir que la lunette tournante soit soumise à l'action de plusieurs dispositifs d'arrêt 13 - 14- 15 au lieu d'un seul, par exemple deux, trois ou quatre, répartis angulairement de façon égale autour de la montre. Alternatively also, it could be provided that the rotating bezel is subjected to the action of several stop devices 13 - 14 - 15 instead of just one, for example two, three or four, angularly distributed equally around the watch.

Il est à remarquer que les positions du dispositif d'arrêt et de la denture avec laquelle il coopère pourraient être interverties, le dispositif d'arrêt étant porté par le corps de boîte et la denture présentée par la lunette tournante. It should be noted that the positions of the stop device and the toothing with which it cooperates could be reversed, the stop device being carried by the box body and the toothing presented by the rotating bezel.

Enfin, il est également à remarquer que la lunette de glace 1 déborde à l'intérieur de l'ouverture centrale. désignée par 17, du corps de boîte dans laquelle est logé un cadre d'encageage 18 pour le mouvement de la montre, non représenté, le cadran ayant été indiqué en 19. Grâce à cette disposition, lorsque le mouvement, le cadre d'encageage 18 et le cadran 19 sont désemboîtés, par le fond de la boîte, il est possible d'introduire dans le corps de boîte un mandrin agissant sur la partie intérieure débordante de la lunette de glace 1 pour dégager celle-ci de la manchette la du corps de boîte. Finally, it should also be noted that the window 1 extends beyond the interior of the central opening. designated by 17, of the box body in which is housed a casing frame 18 for the movement of the watch, not shown, the dial having been indicated at 19. Thanks to this arrangement, when the movement, the casing frame 18 and the dial 19 are disengaged, by the bottom of the box, it is possible to introduce into the body of the box a mandrel acting on the projecting inner part of the glass window 1 to release it from the cuff of the box body.

En effet, la présence de la lunette tournante 7 ne permet pas de prévoir, à la périphérie de la lunette de glace. un onglet de démontage de celle-ci. Indeed, the presence of the rotating bezel 7 does not make it possible to foresee, at the periphery of the ice telescope. a disassembly tab of it.

Grâce au fait que la lunette tournante 7 est maintenue en place sur le corps de boîte par la lunette de glace 2 et grâce au fait que le dispositif d'arrêt 13 - 14 - 15 agit radialement. By virtue of the fact that the rotating bezel 7 is held in place on the case body by the glass bezel 2 and by the fact that the stop device 13 - 14 - 15 acts radially.

I'ensemble n'occasionne aucun accroissement de la hauteur de la boîte. The assembly does not cause any increase in the height of the box.
