Description

La présente invention a pour objet une montre à lunette tournante métallique dans laquelle la lunette tournante est munie d'un anneau intérieur en matière synthétique glissant sur la carrure de la montre et comprenant au moins une deuxième pièce en matière synthétique, fixe, l'une des deux pièces en matière synthétique, anneau ou deuxième pièce, étant munie d'une denture et l'autre pièce d'au moins un cliquet coopérant avec la denture pour le positionnement de la lunette tournante.The present invention relates to a watch with a metallic rotating bezel in which the rotating bezel is provided with an inner ring of synthetic material sliding on the middle of the watch and comprising at least one second piece of synthetic material, fixed, one two plastic parts, ring or second part, being provided with a toothing and the other part with at least one pawl cooperating with the toothing for positioning the rotating bezel.

Une montre présentant une telle construction, est décrite dans le brevet CH 662 030. L'anneau intérieur en matière synthétique et muni d'une denture présente un profil en L et il est collé dans un logement cylindrique de la lunette métallique. Les cliquets sont solidaires d'une bague porte-cliquets fixée sur une portée cylindrique de la carrure, autour de la lunette fixe, au moyen d'une bague de tension métallique. Cette bague sert également à la retenue axiale de la lunette tournante par son anneau en matière synthétique. Avec cette construction, la bague porte-cliquets doit être assemblée à la lunette tournante avant le montage de cette bague porte-cliquets sur la boîte de montre. Inversement, si l'on doit enlever l'un des éléments de la lunette tournante, c'est l'ensemble avec la bague porte-cliquets, qui doit être enlevé. Si l'une des pièces de l'ensemble vient à se casser, c'est l'ensemble qui est remplacé. Dans tous les cas le remplacement de l'anneau denté ne peut se faire sans remplacer également la lunette métallique.A watch having such a construction is described in patent CH 662 030. The inner ring of synthetic material and provided with teeth has an L-shaped profile and it is glued in a cylindrical housing of the metal bezel. The pawls are secured to a pawl ring fixed to a cylindrical seat of the middle, around the fixed bezel, by means of a metal tension ring. This ring is also used for the axial retention of the rotating bezel by its synthetic ring. With this construction, the pawl ring must be assembled with the rotating bezel before mounting this pawl ring on the watch case. Conversely, if one of the elements of the rotating bezel has to be removed, the assembly with the ratchet ring must be removed. If one of the parts of the assembly breaks, the assembly is replaced. In all cases, the replacement of the toothed ring cannot be done without also replacing the metal bezel.

La présente invention a pour objet une conception différente. Elle a pour but de permettre le montage successif et sans outil particulier de la bague porte-cliquets sur la carrure, puis de la lunette tournante. En outre, la partie synthétique de la lunette tournante doit pouvoir être remplacée facilement.The subject of the present invention is a different conception. Its purpose is to allow the successive assembly and without any special tool, the pawl ring on the middle, then the rotating bezel. In addition, the synthetic part of the rotating bezel must be able to be replaced easily.

La montre à lunette tournante selon l'invention est caractérisée par le fait que l'anneau intérieur en matière synthétique est fixé à cran à la lunette tournante et que l'autre pièce en matière synthétique est maintenue en place d'une part par au moins un pied engagé dans un trou prévu dans la carrure et d'autre part par la lunette tournante.The rotating bezel watch according to the invention is characterized in that the inner ring of synthetic material is fixed to the rotating bezel and that the other piece of synthetic material is held in place on the one hand by at least one foot engaged in a hole provided in the middle and on the other hand by the rotating bezel.

L'anneau intérieur est donc fixé sans collage à la lunette tournante, ce qui permet de l'enlever en cas de défectuosité et de le remplacer par une nouvelle pièce. L'assemblage est très simple : on place tout d'abord la bague porte-cliquets dont les pieds viennent s'introduire dans les trous prévus à cet effet dans la carrure, puis on met en place la lunette tournante avec son anneau en matière synthétique. La lunette tournante peut être retenue axialement, soit directement par son anneau synthétique présentant à cet effet un profil approprié, soit par une bague fendue d'assemblage. Dans les deux cas c'est la lunette tournante qui vient retenir axialement la bague porte-cliquets.The inner ring is therefore fixed without gluing to the rotating bezel, which makes it possible to remove it in the event of a defect and to replace it with a new part. Assembly is very simple: first place the pawl ring, the feet of which are introduced into the holes provided for this purpose in the middle, then the rotating bezel is put in place with its synthetic ring . The rotating bezel can be retained axially, either directly by its synthetic ring having for this purpose an appropriate profile, or by a split assembly ring. In both cases it is the rotating bezel which axially retains the pawl ring.

Si une réparation est nécessaire, il est possible d'enlever la lunette tournante sans enlever la bague porte-cliquets ou les cliquets individuels. Cette bague porte-cliquets, respectivement l'un ou l'autre des cliquets individuels peuvent être enlevés et remplacés sans outil spécial. Les fonctions peuvent être inversées, c'est-à-dire que la lunette tournante peut être munie d'une bague porte-cliquets, tandis qu'un anneau denté muni de pieds est retenu en rotation sur la carrure. Le service après vente est donc grandement simplifié. Il est en outre important de pouvoir changer l'anneau denté et/ou les cliquets sans changer la lunette tournante métallique qui est une pièce sensiblement plus coûteuse que les pièces en matière synthétique.If repair is necessary, it is possible to remove the rotating bezel without removing the pawl ring or the individual pawls. This pawl ring, respectively one or the other of the individual pawls can be removed and replaced without special tools. The functions can be reversed, i.e. the rotating bezel can be fitted with a ratchet ring, while a ring toothed with feet is retained in rotation on the middle. After-sales service is therefore greatly simplified. It is also important to be able to change the toothed ring and / or the pawls without changing the metallic rotating bezel which is a part which is significantly more expensive than the parts made of synthetic material.

En plus de ces avantages, la montre selon l'invention présente également les avantages de l'exécution antérieure, à savoir possibilité d'utiliser n'importe quelle matière pour la lunette tournante et la boîte en ayant une rotation aisée de cette lunette tournante sur la boîte, régularité de la friction, absence totale de corrosion au niveau de l'encliquetage, précision du cliquetage et résistance physique de celui-ci.In addition to these advantages, the watch according to the invention also has the advantages of the previous embodiment, namely the possibility of using any material for the rotating bezel and the case by easily rotating this rotating bezel on the box, regularity of the friction, total absence of corrosion at the level of the snap, precision of the snap and physical resistance of this one.

La montre à lunette tournante représentée à la figure 1 comprend une carrure 1 présentant une lunette 2 dans laquelle est fixée une glace 3 au moyen d'une garniture 4. On a également représenté le passage 5 pour la tige de mise à l'heure. Autour de la lunette fixe 2, la carrure 1 présente une portée plane 6 dans laquelle sont ménagées trois gorges 7 équidistantes, en arc de cercle. Près de l'une des extrémités de ces gorges 7, le fond de la gorge présente un trou borgne 8. Dans chacune des gorges 7 est logé un cliquet 9 tel que représenté aux figures 3 et 4. Chacun de ces cliquets 9 en matière synthétique présente un socle 10 de forme générale rectangulaire et muni d'un pied cylindrique 11 venant se loger librement dans le trou borgne 8 de la carrure. A partir du socle 10 s'étend un bras élastique 12 terminé par un bec de cliquet 13. Le bras élastique 12 est bien entendu plus mince que le socle 10 de telle sorte que par la flexion du bras 12, le bec de cliquet 13 peut s'escamoter complètement dans la gorge 7. De manière à assurer une meilleure tenue circonférencielle du cliquet, le socle 10 est muni de bourrelets verticaux 14, 15, 16 et 17 à ses angles. Ces bourrelets viennent s'engager dans des gorges verticales telles que 18 prévues dans les parois de la gorge 7.The rotating bezel watch shown in FIG. 1 comprises a middle part 1 having a bezel 2 in which a crystal 3 is fixed by means of a trim 4. The passage 5 is also shown for the time-setting rod. Around the fixed bezel 2, the middle part 1 has a flat surface 6 in which three equidistant grooves 7 are formed, in an arc of a circle. Near one end of these grooves 7, the bottom of the groove has a blind hole 8. In each of the grooves 7 is housed a pawl 9 as shown in Figures 3 and 4. Each of these pawls 9 made of synthetic material has a base 10 of generally rectangular shape and provided with a cylindrical foot 11 which is freely housed in the blind hole 8 of the middle part. From the base 10 extends an elastic arm 12 terminated by a ratchet beak 13. The elastic arm 12 is of course thinner than the base 10 so that by bending the arm 12, the ratchet beak 13 can retract completely into the groove 7. In order to ensure better circumferential strength of the pawl, the base 10 is provided with vertical beads 14, 15, 16 and 17 at its angles. These beads come to engage in vertical grooves such as 18 provided in the walls of the groove 7.

La montre est munie d'une lunette tournante en métal 19 présentant une portée 19a venant recouvrir la lunette fixe 2. Sous la portée 19a, la lunette tournante 19 présente une gorge radiale annulaire 20 et en dessous de cette gorge 20 une portée plane 21 s'étendant jusque dans une seconde gorge radiale annulaire 22. Les gorges 20 et 22 forment deux crans dans lesquels vient se fixer à cran un anneau en matière synthétique 23 présentant un profil correspondant au profil intérieur de la lunette tournante en métal 19. Au niveau des deux crans, le pourtour de l'anneau synthétique 23 présente deux biseaux 23a et 23b permettant la fixation de l'anneau 23 par simple pression. L'anneau 23 est en outre bloqué en rotation par au moins un bossage venant s'engager dans une gorge 25 de la lunette tournante en métal 19. Les bossages de l'anneau 23 peuvent avoir la forme du bossage apparaissant à la figure 6. L'anneau en matière synthétique 23 présente intérieurement une saillie annulaire 26 par laquelle elle est retenue axialement sur un cran 27 de la carrure 1. L'anneau 23 présente une denture en dents de loup 28 coopérant axialement avec les cliquets 9. Dans ce cas la lunette tournante 19 ne peut donc tourner que dans une seule direction. Il serait toutefois possible de former une denture telle que la lunette tournante puisse tourner dans les deux directions.The watch is provided with a metal rotating bezel 19 having a scope 19a covering the fixed bezel 2. Under the scope 19a, the rotating bezel 19 has an annular radial groove 20 and below this groove 20 a flat surface 21 extending as far as a second annular radial groove 22. The grooves 20 and 22 form two notches in which a plastic ring 23 is fixed to the notch having a profile corresponding to the internal profile of the rotating metal bezel 19. At the two notches, the periphery of the synthetic ring 23 has two bevels 23a and 23b allowing the fixing of the ring 23 by simple pressure. The ring 23 is also locked in rotation by at least one boss coming into engagement in a groove 25 of the rotating metal bezel 19. The bosses of the ring 23 can have the shape of the boss appearing in FIG. 6. The ring made of synthetic material 23 has internally an annular projection 26 by which it is retained axially on a notch 27 of the middle part. The ring 23 has a toothed serration 28 cooperating axially with the pawls 9. In this case the rotating bezel 19 can therefore only rotate in one direction. It would however be possible to form a toothing such that the rotating bezel can rotate in both directions.

Pour monter cette lunette tournante, on met tout d'abord en place les cliquets 9, puis on fixe la lunette tournante 19, munie de son anneau 23, par une simple pression. Les biseaux prévus sur le bord extérieur de la lunette fixe 2 et à la base de la saillie 26 et l'élasticité de la matière synthétique de l'anneau 23 permettent d'exécuter facilement ce montage.To mount this rotating bezel, first put the pawls 9 in place, then fix the rotating bezel 19, provided with its ring 23, by a simple pressure. The bevels provided on the outer edge of the fixed bezel 2 and at the base of the projection 26 and the elasticity of the synthetic material of the ring 23 allow this assembly to be easily carried out.

Au lieu de cliquets segmentés, il est possible d'utiliser une bague munie d'un ou plusieurs cliquets, telle que représentée aux figures 5 et 6. Cette bague 29 en matière synthétique est également muni d'un pied cylindrique 30 et d'un bossage latéral 31. La bague 29 est munie d'un ou plusieurs cliquets 32 présentant un bec de cliquet 33 faisant saillie au-dessus de la bague. Dans ce cas, la gorge 7 prévue dans la carrure 1 s'étend sur tout le pourtour de cette carrure pour recevoir la bague 29. Le pied 30 de la bague 29 vient se loger dans un trou identique au trou 8. Quant au bossage 31, il vient se loger dans une gorge analogue à la gorge 25 pour fixer la bague 29 en rotation.Instead of segmented pawls, it is possible to use a ring provided with one or more pawls, as shown in FIGS. 5 and 6. This ring 29 in synthetic material is also provided with a cylindrical foot 30 and a lateral boss 31. The ring 29 is provided with one or more pawls 32 having a pawl beak 33 projecting above the ring. In this case, the groove 7 provided in the middle part 1 extends over the entire periphery of this middle part to receive the ring 29. The foot 30 of the ring 29 is housed in a hole identical to the hole 8. As for the boss 31 , it is housed in a groove similar to the groove 25 to fix the ring 29 in rotation.

Il est possible d'inverser la position des fonctions denture et cliquet. La figure 7 montre, à titre d'exemple, la même lunette 19 équipée d'un anneau 34 en matière synthétique dans lequel est formé au moins un cliquet 35 destiné à coopérer avec un anneau denté logé à la place de la bague porte-cliquets 29. Pour le reste, l'anneau 34 est identique à l'anneau 23.It is possible to reverse the position of the toothing and ratchet functions. FIG. 7 shows, by way of example, the same bezel 19 fitted with a ring 34 made of synthetic material in which at least one pawl 35 is formed intended to cooperate with a toothed ring housed in place of the pawl ring 29. For the rest, the ring 34 is identical to the ring 23.

En conservant la plupart des avantages de la première forme d'exécution, il est possible de monter la lunette tournante sur la carrure au moyen d'une bague auxiliaire. La figure 8 représente un exemple d'exécution. La carrure 1 est la même que celle de la première forme d'exécution. Par contre, la lunette tournante métallique 36 est plus basse que la lunette 19 elle est munie intérieurement d'une gorge 37. L'assemblage est réalisé au moyen d'une bague fendue en métal 38 de profil rectangulaire munie de deux biseaux diagonalement opposés. La bague fendue est tout d'abord fixée dans une gorge 39 de la carrure 1 avec un certain jeu radial. La lunette 36 est ensuite engagée avec une pression sur la bague d'assemblage 38. Celle-ci s'escamote tout d'abord dans la gorge 39, puis se détend dans la gorge 37 de la lunette tournante. Ce mode de fixation est bien connu.While retaining most of the advantages of the first embodiment, it is possible to mount the rotating bezel on the middle by means of an auxiliary ring. Figure 8 shows an example of execution. The middle part 1 is the same as that of the first embodiment. By cons, the metallic rotating bezel 36 is lower than the bezel 19 it is provided internally with a groove 37. The assembly is carried out by means of a split metal ring 38 of rectangular profile provided with two diagonally opposite bevels. The split ring is firstly fixed in a groove 39 of the middle part 1 with a certain radial clearance. The bezel 36 is then engaged with pressure on the assembly ring 38. This first retracts into the groove 39, then relaxes in the groove 37 of the rotating bezel. This method of attachment is well known.

La lunette tournante 36 est munie d'un anneau denté 40 sensiblement plus petit que dans la première forme d'exécution, mais également fixé à cran dans une rainure 41. Cet anneau 40 est également verrouillé en rotation par au moins un bossage engagé dans une gorge 42 de la lunette tournante. L'anneau denté 40 travaille avec une bague porte-cliquets 29 tel que représenté aux figures 5 et 6.The rotating bezel 36 is provided with a toothed ring 40 substantially smaller than in the first embodiment, but also fixed to the notch in a groove 41. This ring 40 is also locked in rotation by at least one boss engaged in a groove 42 of the rotating bezel. The toothed ring 40 works with a pawl ring 29 as shown in FIGS. 5 and 6.

Le montage pourrait aussi se faire au moyen d'une bague non fendue.The assembly could also be done by means of an unsplit ring.
