This ring-shaped part (8a) is fitted into an indentation (7) in the rim (3) and its toothed part meshes with a pinion (16) with an axial aperture of square cross-section fitting onto a segment (15a) of complementary cross-section on the winding stem (15). The pinion (16) is located in a case (14) open laterally on the external surface of the rim (3) and maintained in this case (14) by a shutting device (17). The winding stem (15) can be axially moved between at least two positions while remaining constantly meshed with the rotating bezel (8) by means of the pinion (16) allowing the rewinding or setting of the watch by rotating the bezel (8).

Description

MONTRE WATCH
La présente invention se rapporte à une montre compre- nant un boîtier muni d'une lunette tournante dont une partie annulaire est dentée, une tige de remontoir présentant un tronçon de section polygonale situé à l'extérieur du mouve¬ ment de la montre, un pignon muni d'une ouverture de section complémentaire à celle dudit tronçon, engagé sur celui-ci, la denture du pignon étant en prise avec celle de ladite partie annulaire dentée, formant une liaison cinématique en¬ tre la lunette tournante et la tige de remontoir.The present invention relates to a watch comprising a case provided with a rotating bezel, an annular part of which is toothed, a winding stem having a section of polygonal section located outside the movement of the watch, a pinion provided with an opening of complementary section to that of said section, engaged thereon, the toothing of the pinion being engaged with that of said annular toothed part, forming a kinematic connection between the rotating bezel and the winding stem .
De telles montres ont déjà été décrites dans le CH 1825 et le CH 72852. Dans chacune des solutions proposées, la lu- nette tournante vient en prise avec une roue dentée associée à une bascule destinée à relier sélectivement la lunette tournante au mécanisme de remontage du ressort de barillet ou à l'engrenage de mise à l'heure.Such watches have already been described in CH 1825 and CH 72852. In each of the solutions proposed, the rotating bezel engages with a toothed wheel associated with a rocker intended to selectively connect the rotating bezel to the winding mechanism of the barrel spring or time setting gear.
Ces solutions nécessitent une transformation complète du mouvement de la montre, de sorte que seules des montres équipées de tels mouvements peuvent être remontées par la lunette tournante.These solutions require a complete transformation of the watch movement, so that only watches equipped with such movements can be wound by the rotating bezel.
On a proposé une autre solution dans le CH 662235 dans laquelle la lunette tournante est munie d'une denture qui vient en prise, d'une part, avec un pignon solidaire de la tige de remontoir, d'autre part, avec une roue d'un mécanis¬ me de mise à l'heure monté sur une platine auxiliaire. Le but de cette solution est de permettre d'associer un méca¬ nisme de remontage et de mise à l'heure par la lunette tour- nante sans transformer le mouvement, mais en lui ajoutant un module supplémentaire monté sur la platine auxiliaire.Another solution has been proposed in CH 662235 in which the rotating bezel is provided with a toothing which engages, on the one hand, with a pinion secured to the winding stem, on the other hand, with a wheel d 'a time setting mechanism mounted on an auxiliary plate. The aim of this solution is to allow a winding mechanism and time-setting mechanism to be associated by the rotating bezel without transforming the movement, but by adding an additional module mounted on the auxiliary plate.
Une telle montre présente cependant plusieurs incon¬ vénients. Elle nécessite un mécanisme supplémentaire et la platine auxiliaire qui le porte augmente sensiblement la hauteur du mouvement. En outre, si l'on veut remonter la montre, en même temps, on entraîne la bascule de mise à l'heure qui, au bout d'un certain angle de rotation met en prise un renvoi porté par la bascule avec un pignon de mise à l'heure, de sorte que si l'on ne fait pas attention de ne pas dépasser cet angle de rotation de la lunette, on change l'heure, alors qu'on désire seulement remonter la montre.However, such a watch has several drawbacks. It requires an additional mechanism and the auxiliary plate which carries it significantly increases the height of the movement. In addition, if we want to wind the watch, at the same time, we cause the the hour which, at the end of a certain angle of rotation engages a reference carried by the rocker with a time-setting pinion, so that if one is not careful not to exceed this angle of rotation of the bezel, we change the time, when we only want to wind the watch.
D'autres systèmes de remontage et de mise à l'heure par la lunette ont été décrits dans le CH-A-316 834, ainsi que dans le CH-A-65 378. Dans les deux cas, le pignon qui engrè¬ ne avec la couronne dentée de la lunette tournante est tota- lement solidaire de la tige de remontoir en rotation et en translation. Dans le premier de ces deux documents, le dé¬ placement de la tige de remontoir fait partiellement sortir la denture du pignon de la couronne dentée de la lunette, risquant ainsi d'endommager ces dentures. Le second de ces documents ne présente pas cet inconvénient, étant donné que la largeur de la couronne dentée a été augmentée en consé¬ quence pour engrener avec le pignon de la tige de remontoir dans les deux positions axiales de celle-ci. Cette solution, destinée à une montre de bord de voiture, ne conviendrait pas à une montre bracelet, étant donné qu'elle augmenterait la largeur de la carrure, nuisant à l'esthétique de la boî¬ te.Other winding and time-setting systems by the bezel have been described in CH-A-316 834, as well as in CH-A-65 378. In both cases, the pinion which engages with the ring gear of the rotating bezel is completely secured to the winding stem in rotation and in translation. In the first of these two documents, the movement of the winding stem partially causes the teeth of the pinion to come out of the ring gear of the bezel, thereby risking damage to these teeth. The second of these documents does not have this drawback, given that the width of the ring gear has been increased accordingly to mesh with the pinion of the winding stem in the two axial positions thereof. This solution, intended for a car dashboard watch, would not be suitable for a wristwatch, since it would increase the width of the middle, detracting from the aesthetics of the box.
Bien que le fait de ménager un tronçon de tige de re¬ montoir de section carrée, permettant d'entraîner le pignon coulant dans toutes ses position axiales, de remontage et de mise à l'heure, est bien connu de tous les mécanismes de re¬ montoirs depuis bientôt un siècle, il ne s'agit cependant pas dans ce cas, de maintenir ce pignon coulant fixe axiale¬ ment. Au contraire, ce pignon coulant est déplacé axialement en sens inverse de la tige de remontoir, par l'intermédiaire de la tirette et de la bascule de mise à l'heure, pour le mettre en prise avec le renvoi de mise à l'heure.Although the fact of providing a section of re¬ stem of square section, allowing to drive the sliding pinion in all its axial position, winding and setting the time, is well known to all re mechanisms ¬ mounts for almost a century, it is not, however, in this case, to keep this sliding pinion axially fixed axially. On the contrary, this sliding pinion is moved axially in the opposite direction of the winding stem, by means of the zipper and the time-setting rocker, to put it in engagement with the time-setting reference. .
Le but de la présente invention est de remédier, au moins en partie, aux inconvénients susmentionnés et de faire en sorte que le remontage de la montre qui était perçu jus¬ qu'ici comme une opération négative, et qui a été supprimé dans les montre automatiques et électriques, devienne quel¬ que chose de plaisant et d'amusant et qui, contrairement à une montre à remontage par la tige de remontoir, se remonte plus aisément en la gardant au poignet. Comme on le verra dans la description qui va suivre, outre la conception pure¬ ment mécanique du dispositif de remontage, des dispositions ont été prises pour le protéger de la poussière et pour as¬ surer une longue durée de vie de la lunette tournante et des joints de protection. A cet effet, cette invention a pour objet une montre du type susmentionné, caractérisée par le fait que ledit pignon est positionné axialement entre deux butées solidaires du boîtier, ledit tronçon de section polygonale de la tige de remontoir présentant une longueur choisie pour permettre de déplacer axialement ladite tige de remontoir entre au moins deux positions, l'une de remontage et l'autre de mise à l'heure, tout en maintenant la liaison cinématique entre la lunette et la tige de remontoir par l'intermédiaire dudit pignon. Selon d'autres particularités de cette invention, on mentionnera que, de préférence, le ressort normal d'une mon¬ tre à remontage manuel est remplacé par un ressort à bride glissante tel que ceux utilisés dans les montres à remontage automatique. En effet, la lunette tournante permet d'exercer sur le ressort un couple sensiblement plus élevé que celui exercé par l'intermédiaire de la tige de remontoir. Par conséquent, il est extrêmement avantageux qu'une fois le ressort moteur complètement armé, il puisse glisser dans le barillet, de sorte que l'on peut continuer indéfiniment à tourner la lunette, bien que le ressort soit complètement armé, sans risque de détérioration du ressort.The object of the present invention is to remedy, at least in part, the abovementioned drawbacks and to ensure that the winding of the watch which has been perceived hitherto as a negative operation, and which has been eliminated in automatic and electric watches, it becomes something pleasant and fun and which, unlike a watch wound by the winding stem, is more easily wound by keeping it on the wrist. As will be seen in the following description, in addition to the purely mechanical design of the winding device, arrangements have been made to protect it from dust and to ensure a long service life of the rotating bezel and protective seals. To this end, the subject of this invention is a watch of the aforementioned type, characterized in that said pinion is positioned axially between two abutments integral with the case, said polygonal section of the winding stem having a length chosen to allow movement axially said winding rod between at least two positions, one for winding and the other for setting the time, while maintaining the kinematic connection between the bezel and the winding rod via said pinion. According to other particularities of this invention, it will be mentioned that, preferably, the normal spring of a manual winding watch is replaced by a sliding strap spring such as those used in watches with automatic winding. Indeed, the rotating bezel allows to exert on the spring a torque significantly higher than that exerted via the winding stem. Therefore, it is extremely advantageous that once the mainspring is fully cocked, it can slide into the barrel, so that the bezel can be continued indefinitely, although the spring is fully cocked, without risk of damage. spring.
Puisque dans ce cas, le remontage est sans fin, l'uti¬ lisateur ne sait pas si le ressort est ou non armé. Il peut donc être avantageux d'ajouter un indicateur du degré d'ar- mage du ressort moteur, qui est un dispositif connu en soi. La montre selon l'invention ne nécessite aucune modifi¬ cation en ce qui concerne le mouvement proprement dit, la seule modification nécessaire est celle de la tige de re¬ montoir. Il est donc possible, grâce à la présente inven- tion, d'adapter le système de remontage à n'importe quelle montre en changeant seulement la tige de remontoir.Since in this case the winding is endless, the user does not know if the spring is armed or not. It may therefore be advantageous to add an indicator of the degree of arming of the mainspring, which is a device known per se. The watch according to the invention does not require any modification as regards the actual movement, the only modification necessary is that of the re¬ mount rod. It is therefore possible, thanks to the present invention, to adapt the winding system to any watch by only changing the winding stem.
Le dessin annexé illustre, schématiquement et à titre d'exemple, une forme d'exécution de la montre objet de la présente invention. La figure 1 est une vue partielle en coupe axiale de cette montre.The appended drawing illustrates, schematically and by way of example, an embodiment of the watch which is the subject of the present invention. Figure 1 is a partial view in axial section of this watch.
La figure 2 est une vue agrandie d'un détail de la figure 1.Figure 2 is an enlarged view of a detail of Figure 1.
La montre illustrée par cette figure comporte un mouvement 1 recouvert d'un cadran indicateur 2, logé dans un boîtier comprenant une carrure 3, un fond 4 et une glace 5.The watch illustrated by this figure comprises a movement 1 covered with an indicator dial 2, housed in a case comprising a middle part 3, a base 4 and a crystal 5.
La partie supérieure de la carrure 3 présente un évidement annulaire 6 dans le fond duquel est ménagée une rainure annulaire 7. Une lunette tournante 8 est disposée dans l'évidement annulaire 6 et est retenue axialement par des chevilles 9a ménagées dans le prolongement de l'ex¬ trémité de vis 9, traversant radialement la lunette tournan¬ te 8 et réparties angulairement autour d'elle. Ces chevilles 9a sont engagées dans une rainure annulaire 10 de la face latérale de l'évidement annulaire 6. Une rainure annulaire 11 parallèle à la rainure annulaire 10 sert à recevoir un joint 0-ring 12. Un second joint 13 est logé dans une rainu¬ re annulaire 23, ménagée dans la face inférieure de la lu¬ nette tournante 8. Comme on peut le voir sur la figure 2, de préférence, ce joint 13 a une section semi-circulaire, sa face plane étant collée dans le fond de la rainure 23. La forme du joint 13 et le collage de celui-ci permettent d'augmenter sa durée de vie et facilitent la rotation de la lunette tournante 8 dans les deux sens. Le joint 12, quant à lui, est de préférence un joint O-ring. La face inférieure de cette lunette tournante 8 pré¬ sente encore une partie annulaire saillante 8a à l'extrémité de laquelle une denture de chant 8b est ménagée, cette par¬ tie annulaire 8a étant logée dans la rainure annulaire 7. Cette rainure 7 communique avec un logement cylindrique 14, dont l'axe de révolution coïncide avec l'axe de la tige de remontoir 15. Cette tige de remontoir 15 comporte un tronçon de section carrée 15a qui traverse une ouverture de même section, centrée sur l'axe d'un pignon 16 engrenant avec la denture 8b. Un organe de fermeture 17, porteur d'un tube 18 muni d'un joint 0-ring 19 destiné à coopérer avec une couronne de remontoir 20 est emboîté dans le logement cylindrique 14 par deux vis (non représentées), fixées dans la carrure 3 de part et d'autre de la tige de remontoir 15. De ce fait, le pignon 16 est fixé axialement entre deux bu¬ tées constituées par le fond du logement cylindrique 14 d'une part, et la face interne de l'organe de fermeture 17. La face latérale de ce dernier présente une rainure 17a dans laquelle est logé un joint 0-ring 24. Des entretoises, 21, 22, par exemple en nylon, peuvent être disposées de part et d'autre de ce pignon 16 pour éviter son grippage. Grâce à cette disposition, le tronçon de section carrée 15a de la tige de remontoir 15 peut coulisser librement à travers l'ouverture du pignon 16 et celui-ci reste en prise avec la denture 8b de la lunette tournante. De ce fait, la tige de remontoir 15 peut occuper différentes positions, deux ou trois pour le remontage, la mise à l'heure, voire la mise à la date, comme une tige de remontoir normale, la liaison cinématique restant constamment établie entre la lunette tournante 8 et la tige de remontoir 15, par l'intermédiaire du pignon 16 solidaire en rotation de cette tige 15 grâce au tronçon 15a de section carrée.The upper part of the middle part 3 has an annular recess 6 in the bottom of which is formed an annular groove 7. A rotating bezel 8 is arranged in the annular recess 6 and is held axially by pins 9a formed in the extension of the ex¬ screw end 9, passing radially through the rotating bezel 8 and distributed angularly around it. These pins 9a are engaged in an annular groove 10 on the side face of the annular recess 6. An annular groove 11 parallel to the annular groove 10 serves to receive a 0-ring seal 12. A second seal 13 is housed in a groove ¬ annular re 23, formed in the underside of the rotating lu¬ net 8. As can be seen in Figure 2, preferably, this seal 13 has a semi-circular section, its flat face being glued in the bottom of the groove 23. The shape of the seal 13 and the bonding thereof make it possible to increase its service life and facilitate rotation of the rotating bezel 8 in both directions. The seal 12, meanwhile, is preferably an O-ring seal. The underside of this rotating bezel 8 also has a projecting annular portion 8a at the end of which an edge toothing 8b is provided, this annular portion 8a being housed in the annular groove 7. This groove 7 communicates with a cylindrical housing 14, whose axis of revolution coincides with the axis of the winding rod 15. This winding rod 15 comprises a section of square section 15a which passes through an opening of the same section, centered on the axis of a pinion 16 meshing with the teeth 8b. A closing member 17, carrying a tube 18 provided with a 0-ring seal 19 intended to cooperate with a winding crown 20 is fitted into the cylindrical housing 14 by two screws (not shown), fixed in the middle part 3 on either side of the winding stem 15. As a result, the pinion 16 is fixed axially between two bu¬ tees constituted by the bottom of the cylindrical housing 14 on the one hand, and the internal face of the member closure 17. The lateral face of the latter has a groove 17a in which is housed a 0-ring seal 24. Spacers, 21, 22, for example made of nylon, can be placed on either side of this pinion 16 to avoid seizing. Thanks to this arrangement, the square section 15a of the winding stem 15 can slide freely through the opening of the pinion 16 and the latter remains in engagement with the teeth 8b of the rotating bezel. As a result, the winding stem 15 can occupy different positions, two or three for winding, setting the time, even setting the date, like a normal winding stem, the kinematic link remaining constantly established between the rotating bezel 8 and the winding stem 15, via the pinion 16 integral in rotation with this stem 15 by virtue of the section 15a of square section.
On constate donc bien qu'aucune modification ni adjonc¬ tion n'est nécessaire en ce qui concerne le mécanisme d'hor- logerie proprement dit. Les modifications interviennent seu¬ lement au niveau du boîtier et de la partie de la tige de remontoir extérieure au mouvement. Avantageusement et afin de permettre de tourner indéfiniment la lunette tournante 8, ce qui peut présenter un certain côté ludique pour l'utili¬ sateur, on peut utiliser un ressort de barillet à bride glissante comme dans une montre automatique. Ceci permet d'éviter tout risque de détérioration du ressort moteur.It can therefore be seen that no modification or addition is necessary with regard to the clock mechanism itself. The modifications take place only at the level of the housing and of the part of the rod. external winding movement. Advantageously and in order to allow the rotating bezel 8 to be rotated indefinitely, which may have a certain playful side for the user, it is possible to use a barrel spring with sliding strap as in an automatic watch. This avoids any risk of damage to the mainspring.
On peut aussi remarquer que le mécanisme de remontage et de mise à l'heure est entièrement protégé contre les in¬ filtrations d'eau et de poussière par des joints d'étanchéi- té, mettant ainsi ce mécanisme à l'abri d'une détérioration ou d'un grippage des pièces mobiles lunette tournante 8 et pignon 16.We can also note that the winding and time-setting mechanism is fully protected against water and dust infiltration by gaskets, thus protecting this mechanism from deterioration or seizure of the moving parts rotating bezel 8 and pinion 16.
L'emboîtage de la montre n'est que très peu modifié par rapport à une boîte normale. Une fois le mouvement mis dans la boîte, avant de fixer le fond 4, on met en place comme d'habitude la tige de remontoir 15 que l'on fixe, comme dans toutes les montres, en vissant la vis de tirette (non représentée). Ensuite, il suffit d'introduire axialement le pignon 16 et de l'engager sur le tronçon de section carrée 15a de cette tige, après quoi on met en place l'organe de fermeture 17 et on le fixe à la carrure 3 par deux vis (non représentées) disposées de part et d'autre de la tige de remontoir 15. Ensuite, il reste à mettre la lunette tour¬ nante 8 en place et à visser les vis de fixation 9 pour retenir la lunette tournante 8 sur la carrure 3, tout en lui permettant de tourner pour entraîner le pignon 16 et la tige de remontoir 15 pour remonter ou mettre la montre à l'heure, suivant la position axiale de cette tige 15. The casing of the watch is only slightly modified compared to a normal case. Once the movement has been placed in the case, before fixing the case back 4, the winding stem 15 is put in place as usual, which is fixed, as in all watches, by screwing the zipper screw (not shown) ). Then, it suffices to introduce the pinion 16 axially and to engage it on the square section section 15a of this rod, after which the closure member 17 is put in place and it is fixed to the middle part 3 by two screws (not shown) arranged on either side of the winding stem 15. Then, it remains to put the rotating bezel 8 in place and to screw the fixing screws 9 to retain the rotating bezel 8 on the middle part 3 , while allowing it to turn to drive the pinion 16 and the winding rod 15 to wind or set the watch on time, according to the axial position of this rod 15.
