Description

La présente invention concerne une montre à lunette tournante avec un système d'indexage comportant une couronne à denture et au moins un cliquet qui s'engage dans ladite denture.The present invention relates to a watch with a rotating bezel with an indexing system comprising a crown with toothing and at least one pawl which engages in said toothing.

Les montres connues de ce type et en particulier leur système d'indexage pour le positionnement de la lunette ne sont pas satisfaisants parce que leur fabrication est relativement onéreuse et/ou le montage est également trop compliqué et coûteux, et/ou le choix des matériaux est limité.Known watches of this type and in particular their indexing system for positioning the bezel are not satisfactory because their manufacture is relatively expensive and / or the assembly is also too complicated and expensive, and / or the choice of materials. is limited.

EP-0 216 420 divulgue un dispositif de lunette tournante pourvue d'une denture venue d'une pièce ou fixée solidairement avec celle-ci, coopérant avec une bague comportant des cliquets, ceux-ci (bague et cliquets) et la denture de la lunette étant obligatoirement en matière synthétique. Une bague de tension est chassée sur la bague porte-cliquets. La liaison axiale de l'ensemble formé la lunette tournante, le porte-cliquets et la bague de tension, ensemble fiché sur une portée cylindrique de la carrure apparaît incertaine, si ce n'est la liaison de la lunette seule. De plus, en cas de désordres, tout l'ensemble précité devra être changé.EP-0 216 420 discloses a rotating bezel device provided with a toothing coming from one piece or fixed integrally with it, cooperating with a ring comprising pawls, these (ring and pawls) and the toothing of the glasses must be made of synthetic material. A tension ring is driven out on the pawl ring. The axial connection of the assembly formed by the rotating bezel, the pawl-holder and the tension ring, all fitted onto a cylindrical surface of the middle part appears uncertain, if it is not the connection of the bezel alone. In addition, in the event of disorders, all of the aforementioned assembly must be changed.

La conception de la lunette tournante décrite dans CH-214 225, en dehors du fait d'impliquer la mise en place d'une lunette de glace, est telle que le démontage et le remplacement de pièces deviennent des opérations délicates impliquant un outillage spécial; il est quasiment exclu que l'utilisateur les fassent lui-même, les risques de provoquer d'autres dommages étant trop grands.The design of the rotating bezel described in CH-214 225, apart from the fact of involving the installation of a window, is such that the dismantling and replacement of parts becomes delicate operations involving special tools; it is almost impossible for the user to do them himself, the risks of causing other damage being too great.

Ainsi, le but de la présente invention est de prévoir une montre à lunette tournante avec un système d'indexage particulièrement simple à fabriquer et à assembler, système qui peut aussi être démonté très facilement pour réparer ou remplacer des parties défectueuses ou trop usées. Cette facilité de montage et de démontage permet l'utilisation d'éléments relativement simples venus d'un matériel notamment métallique ou synthétique qui peut être peu résistant à l'usure, étant donné que ces éléments peuvent facilement être remplacés. Ce but est atteint en ce que le système d'indexage et la lunette sont montés amovibles à l'aide d'éléments élastiques agissant axialement et appuyés sur des parties de la carrure. Les différents organes mis en oeuvre sont des pièces indépendantes qui coopèrent entre elles en étant retenues par les seules actions de forces d'organes de rappel, si bien que toute fixation devient inutile, ce qui permet l'utilisation d'éléments simples et un montage également simple.Thus, the aim of the present invention is to provide a watch with a rotating bezel with an indexing system which is particularly simple to manufacture and assemble, a system which can also be very easily dismantled to repair or replace defective parts or too worn. This ease of assembly and disassembly allows the use of relatively simple elements coming from a material in particular metallic or synthetic which can be not very resistant to wear, given that these elements can easily be replaced. This object is achieved in that the indexing system and the bezel are mounted removable by means of elastic elements acting axially and supported on parts of the middle. The various organs used are independent parts which cooperate with each other while being retained by the sole actions of forces of return members, so that any fixing becomes unnecessary, which allows the use of simple elements and mounting. also simple.

De préférence le ou les cliquet(s) qui coopèrent avec ladite couronne à denture font également partie d'un élément distinct de la lunette et de la carrure, c'est-à-dire d'un élément librement monté entre la carrure et la lunette.Preferably the pawl (s) which cooperate with said ring gear are also part of a separate element of the bezel and the middle part, that is to say of an element freely mounted between the middle part and the glasses.

L'invention sera expliquée en détail à l'aide du dessin qui représente deux exemples d'exécution de la montre selon l'invention.

  • La fig. 1 est une section radiale, et
  • la fig. 2 est une section circonférentielle du premier exemple d'exécution,
  • la fig. 3 est une section radiale, et
  • la fig. 4 est une section circonférentielle du deuxième exemple d'exécution.
The invention will be explained in detail using the drawing which represents two examples of execution of the watch according to the invention.
  • Fig. 1 is a radial section, and
  • fig. 2 is a circumferential section of the first embodiment example,
  • fig. 3 is a radial section, and
  • fig. 4 is a circumferential section of the second exemplary embodiment.

La montre représentée partiellement sur les figures 1 et 2 présente une carrure 1 dans laquelle est montée le mouvement de montre non représenté. La carrure présente deux gorges annulaires 2 et 3 destinées au montage de la lunette 4. Sur le fond 5 d'une gorge annulaire de la lunette 4 se trouvent les repères, par exemple des chiffres et des divisions. La lunette 4 est montée sur la carrure 1 à l'aide d'un ressort fil multipan 6 légerement incliné et s'engageant dans la gorge 2 de la carrure 1 ainsi que dans une gorge 7 de la lunette 4. Par ce ressort 6 la lunette 4 est pressée vers le bas contre un épaulement de la carrure. Une couronne 8 à denture est librement disposée entre la lunette et la carrure. La position angulaire de cette couronne 8 par rapport à la lunette 4 est determinée par des goupilles ou ergots 9 de la couronne 8 qui s'engagent dans des encoches ou des trous 10 de la lunette. Dans la gorge 3 de la carrure 1 se trouve un ressort plat 11 avec quelques ergots ou lames élastiques 12 qui font cliquets et qui s'engagent dans la denture de la couronne 8. Les cliquets 12 sont uniformément répartis autour de la circonférence. En outre, le ressort 11 présente des ergots 13 qui s'engagent dans des encoches 14 de la carrure 1 pour determiner la position angulaire du ressort plat 11 respectivement des cliquets 12 par rapport à la carrure.The watch partially shown in Figures 1 and 2 has a middle part 1 in which is mounted the watch movement not shown. The middle part has two annular grooves 2 and 3 intended for mounting the bezel 4. On the bottom 5 of an annular groove in the bezel 4 are the marks, for example numbers and divisions. The bezel 4 is mounted on the middle part 1 using a slightly inclined multipan wire spring 6 and engaging in the groove 2 of the middle part 1 as well as in a groove 7 of the bezel 4. By this spring 6 the bezel 4 is pressed down against a shoulder of the middle part. A crown 8 with teeth is freely placed between the bezel and the middle part. The angular position of this crown 8 relative to the bezel 4 is determined by pins or lugs 9 of the crown 8 which engage in notches or holes 10 in the bezel. In the groove 3 of the middle part 1 is a flat spring 11 with some lugs or elastic blades 12 which make pawls and which engage in the teeth of the crown 8. The pawls 12 are uniformly distributed around the circumference. In addition, the spring 11 has lugs 13 which engage in notches 14 of the middle part 1 to determine the angular position of the flat spring 11 respectively of the pawls 12 relative to the middle part.

La couronne 8 et le ressort plat 11 constituent ainsi un système d'indexage pour la lunette, système qui est librement maintenu entre la carrure 1 et la lunette 4 simplement sous l'action des ressorts 6 et 11. D'une part, la lunette 4 est maintenue dans sa position représentée par le ressort 6 tandis que la couronne 8 est maintenue dans sa position en contact avec la lunette et avec ses goupilles 9 s'engageant dans les trous 10 par l'élasticité des cliquets 12 venus d'une pièce avec le ressort plat 11. Il est ainsi évident que le système d'indexage est composé d'éléments extrêmement simples et bon marché et que le montage de ce système respectivement de la lunette avec son système d'indexage est également extrêmement simple. Par traction sur la lunette vers le haut on peut l'enlever sous une legère compression du ressort 6 pour remplacer la couronne 8 ou le ressort 11 défectueux. Il est ainsi possible de prévoir une couronne en plastique et ainsi bon marché qui peut facilement être remplacée. Le système se prête au montage avec n'importe quel type de montre et de lunette soit en métal soit en plastique.The crown 8 and the flat spring 11 thus constitute a indexing system for the bezel, a system which is freely maintained between the middle part 1 and the bezel 4 simply under the action of the springs 6 and 11. On the one hand, the bezel 4 is maintained in its position represented by the spring 6 while the crown 8 is held in its position in contact with the bezel and with its pins 9 engaging in the holes 10 by the elasticity of the pawls 12 coming in one piece with the flat spring 11. It is thus obvious that the indexing system is composed of extremely simple and inexpensive elements and that the assembly of this system respectively of the telescope with its indexing system is also extremely simple. By pulling up on the bezel, it can be removed under a slight compression of the spring 6 to replace the defective crown 8 or the spring 11. It is thus possible to provide a plastic crown and thus inexpensive which can easily be replaced. The system is suitable for mounting with any type of watch and bezel either in metal or in plastic.

Dans les figures 3 et 4 des éléments correspondants sont désignés par les mêmes chiffres de référence que dans les figures 1 et 2. L'exemple d'exécution selon les figures 3 et 4 se distingue essentiellement de l'exemple selon les figures 1 et 2 par le fait que la couronne à denture 8 est placée du côté de la carrure 1 tandis que le ressort plat 11 est placé du côté de la lunette 4. Les ergots ou goupilles 9 de la couronne 8 s'engagent dans des trous 15 de la carrure tandis que les lames 13 du ressort 11 s'engagent dans des trous 16 de la lunette 4.In FIGS. 3 and 4, corresponding elements are designated by the same reference numbers as in FIGS. 1 and 2. The example of execution according to FIGS. 3 and 4 differs essentially from the example according to FIGS. 1 and 2 by the fact that the crown gear 8 is placed on the side of the middle part 1 while the flat spring 11 is placed on the side of the bezel 4. The pins or pins 9 of the crown 8 engage in holes 15 of the middle while the blades 13 of the spring 11 engage in holes 16 in the bezel 4.
