Description

La présente invention a pour objet une pièce d'horlogerie comportant une lunette tournante et plus particulièrement le montage et l'encliquetage de la lunette tournante sur la boîte de la pièce d'horlogerie.The present invention relates to a timepiece comprising a rotating bezel and more particularly the mounting and snapping of the rotating bezel on the timepiece box.

Les systèmes actuels de montage et d'encliquetage d'une lunette tournante sur une boîte de montre comportent généralement une crémaillère disposée entre la lunette et la carrure de la boîte, les dents de cette crémaillère s'étendant suivant une direction parallèle à l'axe de symétrie de la boîte de montre et coopérant avec un cliquet. Ces systèmes ne donnent pas entière satisfaction car ils engendrent un jeu radial entre la lunette et la carrure de la boîte de montre. De plus, la fiabilité du couple de rotation n'est pas optimale.Current systems for mounting and latching a rotating bezel on a watch case generally comprise a rack arranged between the bezel and the middle of the box, the teeth of this rack extending in a direction parallel to the axis of symmetry of the watch case and cooperating with a ratchet. These systems are not entirely satisfactory because they generate a radial clearance between the bezel and the middle part of the watch case. In addition, the reliability of the torque is not optimal.

La présente invention a pour but la réalisation d'une pièce d'horlogerie comportant une lunette tournante dans laquelle le montage et l'encliquetage de la lunette tournante sur la boîte de montre permettent une rotation de la lunette avec un jeu minimum sur la boîte et un encliquetage qui permettent de maîtriser le couple de rotation de la lunette.The object of the present invention is to produce a timepiece comprising a rotating bezel in which the mounting and snapping of the rotating bezel on the watch case allows rotation of the bezel with a minimum clearance on the case and a snap that allows to control the torque of rotation of the bezel.

La présente invention a pour objet une pièce d'horlogerie, notamment une montre bracelet ou de poche, comportant une lunette tournante qui se distingue par les caractéristiques énumérées à la revendication 1.The present invention relates to a timepiece, in particular a wristwatch or pocket watch, comprising a rotating bezel which is distinguished by the features listed in claim 1.

La pièce d'horlogerie, selon la présente invention, et dont une forme d'exécution est illustrée au dessin comporte une boîte de montre formée d'une carrure 1 sur laquelle sont fixés un fond 2 et une lunette de fixation 3 d'une glace 4. Cette pièce d'horlogerie comporte encore une lunette tournante 5 montée et encliquetée sur la carrure 1 de la boîte de montre comme décrit dans ce qui suit.The timepiece, according to the present invention, and an embodiment of which is illustrated in the drawing comprises a watch case formed of a middle part 1 on which are fixed a bottom 2 and an attachment window 3 of an ice cream 4. This timepiece further comprises a rotating bezel 5 mounted and snapped on the middle part 1 of the watch case as described below.

La carrure 1 comporte une extension annulaire supérieure 1 a comportant un filetage intérieur coopérant avec un filetage extérieur que comporte la lunette de fixation 3 de la glace 4. Cette carrure 1 comporte une face annulaire extérieure 1 b entourant cette extension annulaire supérieure 1 a dans laquelle est pratiquée une gorge annulaire 6. La paroi annulaire extérieure de cette gorge annulaire 6 comporte au moins une, trois dans l'exemple illustré, creusures 7.The caseband 1 comprises an upper annular extension 1a having an internal thread cooperating with an external threading that comprises the attachment window 3 of the window 4. This middle part 1 comprises an outer annular face 1b surrounding this upper annular extension 1a in which is formed an annular groove 6. The outer annular wall of this annular groove 6 comprises at least one, three in the illustrated example, recesses 7.

Une bague dentée 8 comporte une denture intérieure 9 et sa paroi périphérique externe est munie de formations en saillie 10 dont la forme et la position correspondent à la forme et à l'emplacement des creusures 7 de la paroi périphérique interne de la gorge annulaire 6. Le diamètre extérieur de la bague dentée 8 correspond au diamètre extérieur de la gorge 6 de la carrure 1.A toothed ring 8 has an internal toothing 9 and its outer peripheral wall is provided with protruding formations 10 whose shape and position correspond to the shape and location of the recesses 7 of the inner peripheral wall of the annular groove 6. The outer diameter of the toothed ring 8 corresponds to the outside diameter of the groove 6 of the caseband 1.

Ainsi, en position de service la bague dentée 8 est placée dans la gorge annulaire 6 de la carrure 1, contre sa paroi périphérique extérieure et est positionnée angulairement par rapport à la carrure 1 par les formations en saillie 10 venant se loger dans les creusures 7 de la carrure 1. L'épaisseur radiale de la bague dentée 8 est inférieure à la largeur radiale de la gorge 6 de la carrure 1.Thus, in the service position the toothed ring 8 is placed in the annular groove 6 of the middle part 1, against its outer peripheral wall and is positioned angularly with respect to the middle part 1 by the projecting formations 10 which are housed in the recesses 7 1. The radial thickness of the toothed ring 8 is less than the radial width of the groove 6 of the caseband 1.

La lunette tournante 5 comporte dans sa face inférieure un logement annulaire 11 dans lequel est fixé par encliquetage une bague à cliquet 12. Cette bague à cliquet 12 est retenue dans le logement annulaire 11 de la lunette tournante 5 par l'interaction des rebords d'encliquetage 11 a, 12a que comportent respectivement le logement 11 et la bague à cliquet 12.The rotating bezel 5 has in its underside an annular housing 11 in which is snapped a ratchet ring 12. This ratchet ring 12 is retained in the annular housing 11 of the bezel 5 by the interaction of the ratching flanges 11a, 12a which respectively comprise the housing 11 and the ratchet ring 12.

Cette bague à cliquet comporte une jupe inférieure 13 dont le diamètre interne correspond au diamètre de la paroi interne de la gorge 6 de la carrure et une extension supérieure 14. Cette bague à cliquet 12 comporte encore sur sa périphérie un bossage 17 destiné à coopérer lorsque cette bague à cliquet est encliquetée en position de service sur la lunette tournante, avec une rainure que comporte la paroi annulaire interne de la lunette tournante 5. Ainsi, en position encliquetée sur la lunette tournante 5, la bague à cliquet 12 est solidaire en rotation de la lunette tournante 5.This ratchet ring comprises a lower skirt 13 whose inner diameter corresponds to the diameter of the inner wall of the groove 6 of the middle part and an upper extension 14. This ratchet ring 12 further comprises on its periphery a boss 17 intended to cooperate when this ratchet ring is snapped into the service position on the rotating bezel, with a groove that includes the inner annular wall of the rotating bezel 5. Thus, in the latched position on the rotating bezel 5, the ratchet ring 12 is rotationally secured to of the rotating bezel 5.

Une fois la bague à cliquet 12 encliquetée sur la lunette tournante 5, on place la lunette tournante au-dessus de la carrure 1, introduit la jupe 13 de la bague à cliquet 12 dans la gorge 6 de la carrure 1 et fixe cet ensemble sur la carrure 1 par encliquetage de l'extension supérieure 14 de la bague à cliquet 12 sur l'extension supérieure annulaire 1 a fixant ainsi axialement l'ensemble lunette tournante 5 - bague à cliquet 12 sur la carrure 1 de la boîte de montre.Once the ratchet ring 12 is snapped onto the rotating bezel 5, the rotating bezel is placed above the middle part 1, the skirt 13 of the ratchet ring 12 is introduced into the groove 6 of the caseband 1 and this set is fixed on the caseband 1 by snapping the upper extension 14 of the ratchet ring 12 on the upper annular extension 1 thus axially fixing the rotating bezel assembly 5 - ratchet ring 12 on the middle part 1 of the watch case.

La bague à cliquet 12 comporte plusieurs, dans l'ensemble illustré trois lamelles élastiques 15. Ces lamelles élastiques sont coulées, moulées dans la masse de la bague à cliquet 12 et leurs extrémités libres s'étendent dans des évidements 16 que comporte la jupe 13 de la bague à cliquet. L'extrémité libre de chaque lamelle élastique 15 présente une forme adaptée à coopérer avec les dents de la denture 9 de la bague dentée 8 permettant ainsi d'indexer la lunette tournante 5 sur la carrure 1.The ratchet ring 12 has several, in all illustrated three elastic strips 15. These elastic strips are cast, molded in the mass of the ratchet ring 12 and their free ends extend in recesses 16 that includes the skirt 13 of the ratchet ring. The free end of each resilient blade 15 has a shape adapted to cooperate with the teeth of the toothing 9 of the toothed ring 8 thus making it possible to index the rotating bezel 5 on the middle part 1.

Grâce à la conception de l'assemblage de la lunette tournante 5 sur la carrure 1 on limite au maximum les jeux radiaux des lamelles 15 au nombre de trois ou plus agissant radialement par leur élasticité contre les dents 9 de la bague dentée 8 ce qui réduit encore les jeux radiaux et permet de contrôler très précisément le couple nécessaire à la rotation de la lunette tournante. Le nombre de pièces est limité et le montage de la lunette tournante sur la carrure est très aisé.Thanks to the design of the assembly of the rotating bezel 5 on the caseband 1 is limited to the maximum radial clearances of the blades 15 to the number of three or more acting radially by their elasticity against the teeth 9 of the toothed ring 8 which reduces still the radial clearances and allows to control very precisely the torque necessary for the rotation of the rotating bezel. The number parts is limited and the mounting of the rotating bezel on the middle is very easy.
