L'invention concerne également un système de lunette tournante annulaire comprenant la bague de maintien.The invention also relates to an annular rotating bezel system comprising the retaining ring.

L'invention concerne également une boîte de montre comprenant une carrure et le système de lunette tournante annulaire monté à rotation sur la carrure.The invention also relates to a watch case comprising a middle part and the ring rotating bezel system rotatably mounted on the middle part.

L'invention concerne en outre une montre comportant la boîte de montre. La montre est par exemple une montre de plongée, sans que cela ne soit limitatif dans le cadre de la présente inventionThe invention further relates to a watch comprising the watch case. The watch is for example a diving watch, without this being limiting in the context of the present invention

ETAT DE LA TECHNIQUESTATE OF THE ART

Des systèmes de lunettes tournantes annulaires connus sont munis d'une bague annulaire de maintien du système, destinée à coopérer avec une surface extérieure cylindrique d'une carrure de boîte de montre pour permettre la rotation de la lunette tournante sur la carrure. Une telle bague annulaire de maintien d'un système de lunette tournante est par exemple décrite dans le document brevet EP 2 672 333 A1 . La bague annulaire est une bague plate munie d'un rebord interne comprenant une saillie périphérique. La saillie périphérique coopère avec une excroissance annulaire d'une paroi extérieure de la carrure pour maintenir verticalement le système de lunette tournante sur la carrure, et sert de moyen de guidage en rotation de la lunette tournante autour de la carrure. Toutefois, dans un tel système de lunette tournante, la bague annulaire n'assure pas un bon couple de freinage entre la lunette tournante et la paroi extérieure de la carrure. En outre, lors de la rotation de la lunette tournante autour de la carrure, l'engrènement des différents éléments du système produit un bruit désagréable pour un utilisateur, préjudiciable au ressenti qualitatif de la qualité de la montre équipée que l'utilisateur peut avoir.Known annular rotating eyewear systems are provided with an annular system holding ring, intended to cooperate with a cylindrical outer surface of a watch case middle to allow rotation of the rotating bezel on the middle part. Such an annular ring for maintaining a rotating bezel system is for example described in the patent document EP 2 672 333 A1 . The annular ring is a flat ring provided with an internal rim including a peripheral projection. The peripheral projection cooperates with an annular protrusion of an outer wall of the middle part to maintain vertically the rotating bezel system on the middle part, and serves as a guide means for rotating the rotating bezel around the middle part. However, in such a rotating bezel system, the annular ring does not provide a good braking torque between the rotating bezel and the outer wall of the caseband. In addition, when rotating the rotating bezel around the middle, the meshing of the various elements of the system produces an unpleasant noise for a user, detrimental to the quality felt the quality of the equipped watch that the user can have.

RESUMÉ DE L'INVENTIONSUMMARY OF THE INVENTION

L'invention a donc pour but de fournir une bague annulaire de maintien d'une lunette tournante permettant de garantir un bon couple de freinage entre la lunette tournante et la paroi extérieure de la carrure et de contrôler le bruit produit lors de la rotation de la lunette, tout en conservant un bon guidage en rotation de la lunette tournante autour de la carrure.The invention therefore aims to provide an annular ring for maintaining a rotating bezel to ensure a good braking torque between the rotating bezel and the outer wall of the middle and to control the noise produced during the rotation of the bezel, while maintaining a good guidance in rotation of the rotating bezel around the caseband.

A cet effet, l'invention concerne une bague annulaire de maintien d'un système de lunette tournante qui comprend les caractéristiques mentionnées dans la revendication indépendante 1.To this end, the invention relates to an annular ring for maintaining a rotating bezel system which comprises the features mentioned in the independent claim 1.

Des formes particulières de la bague sont définies dans les revendications dépendantes 2 à 13.Particular shapes of the ring are defined in the dependent claims 2 to 13.

Un premier avantage de la présente invention est d'assurer un bon couple de freinage entre la lunette tournante et la paroi extérieure de la carrure. En effet, grâce à la présence des moyens configurés pour freiner la rotation de la lunette tournante autour de la carrure et pour amortir le son, les différents jeux à l'intérieur du système de lunette tournante sont lissés, de sorte que l'utilisateur de la lunette ne les ressente pas. Le couple de rotation de la lunette est également maîtrisé, en le rendant plus doux et la lunette plus agréable à manipuler. En outre, le bruit produit par la rotation de la lunette est amorti et donne à l'utilisateur une impression de qualité du système de lunette et plus généralement de la montre équipée de ce système.A first advantage of the present invention is to ensure a good braking torque between the rotating bezel and the outer wall of the middle part. Indeed, thanks to the presence of means configured to brake the rotation of the rotating bezel around the middle and to dampen the sound, the various games inside the rotating bezel system are smoothed, so that the user of the glasses do not feel them. The rotating torque of the bezel is also controlled, making it softer and the bezel more comfortable to handle. In addition, the noise produced by the rotation of the bezel is cushioned and gives the user an impression of the quality of the bezel system and more generally of the watch equipped with this system.

De plus, la bague annulaire permet de maintenir les moyens ressort et l'anneau denté dans la lunette tournante, favorisant ainsi le montage de la lunette tournante sur la carrure.In addition, the annular ring keeps the spring means and the toothed ring in the rotating bezel, thereby promoting the mounting of the rotating bezel on the middle part.

Selon un premier mode de réalisation de l'invention, la bague annulaire comprend sur un pourtour une alternance entre des languettes d'un premier groupe de languettes et des languettes d'un second groupe de languettes, les languettes du premier groupe et les languettes du second groupe présentant des dimensions, selon la direction radiale, différenciées, les languettes d'un des premier et second groupes de languettes formant lesdits moyens de guidage en rotation, les languettes de l'autre des premier et second groupes de languettes formant lesdits moyens de freinage et d'amortissement du son. Un avantage de ce premier mode de réalisation est qu'il limite le passage de salissures à l'intérieur du système de lunette tournante, grâce à la présence des différentes languettes qui bloquent de telles salissures.According to a first embodiment of the invention, the annular ring comprises on one periphery an alternation between tongues of a first group of tongues and tongues of a second group of tongues, the tongues of the first group and the tongues of the second group having dimensions, in the radial direction, differentiated, the tongues of one of the first and second groups of tongues forming said rotational guiding means, the tongues of the other of the first and second groups of tongues forming said means for braking and damping sound. An advantage of this first embodiment is that it limits the passage of dirt inside the rotating bezel system, thanks to the presence of the different tabs that block such fouling.

Avantageusement, selon ce premier mode de réalisation, les languettes du premier groupe présentent des dimensions selon la direction radiales inférieures à celles des languettes du second groupe, les languettes du premier groupe formant lesdits moyens de guidage en rotation, les languettes du second groupe étant constituées de segments plus souples que les languettes du premier groupe, lesdits segments étant aptes à fléchir axialement et formant lesdits moyens de freinage et d'amortissement du son. Grâce à la flexibilité axiale des languettes du second groupe, celles-ci peuvent assurer un freinage de la rotation de la lunette tournante autour de la carrure par frottement contre la surface extérieure cylindrique, ainsi qu'un amortissement du son produit.Advantageously, according to this first embodiment, the tongues of the first group have dimensions in the radial direction lower than those of the tongues of the second group, the tongues of the first group forming said rotational guiding means, the tongues of the second group consisting of segments more flexible than the tabs of the first group, said segments being able to flex axially and forming said braking and damping means of sound. Thanks to the axial flexibility of the tongues of the second group, they can provide a braking of the rotation of the rotating bezel around the middle by friction against the cylindrical outer surface, and a damping of the sound produced.

Avantageusement encore, selon ce premier mode de réalisation, les languettes des premier et second groupes sont séparées les unes des autres par des échancrures. Ceci permet notamment d'améliorer la flexibilité des languettes du second groupe de languettes.Advantageously, according to this first embodiment, the tabs of the first and second groups are separated from each other by notches. This notably makes it possible to improve the flexibility of the tongues of the second group of tongues.

Avantageusement encore, selon ce premier mode de réalisation, les premier et second groupes de languettes comprennent chacun six languettes, les languettes des premier et second groupes étant réparties sur 360°, les languettes d'un même groupe de languettes étant espacées deux à deux de 60°. Ceci permet d'améliorer encore le freinage et l'amortissement du bruit, notamment en réduisant encore les jeux à l'intérieur du système et en rendant le couple de rotation encore plus doux.Advantageously, according to this first embodiment, the first and second groups of tongues each comprise six tongues, the tongues of the first and second groups being distributed over 360 °, the tongues of one and the same group of tongues being spaced apart. two by two of 60 °. This further improves the braking and damping of the noise, including further reducing the play inside the system and making the torque even softer.

Selon un deuxième mode de réalisation de l'invention, la bague annulaire comprend sur un pourtour intérieur ou extérieur un ensemble de bossages, lesdits bossages formant lesdits moyens de freinage et d'amortissement du son. Un avantage de ce deuxième mode de réalisation est que les bossages agissent radialement dans un plan dans lequel s'étend la bague, et non perpendiculairement à ce plan comme les languettes du premier mode de réalisation. Grâce à la flexibilité radiale des bossages, ceux-ci peuvent assurer un freinage de la rotation de la lunette tournante autour de la carrure par frottement contre la carrure ou la lunette, ainsi qu'un amortissement du son produit. Dans une première variante de ce deuxième mode de réalisation, les bossages sont agencés sur un pourtour intérieur de la bague pour coopérer avec une surface extérieure cylindrique de la carrure, la bague annulaire étant destinée à être solidarisée à la lunette tournante. Dans une seconde variante de ce deuxième mode de réalisation, les bossages sont agencés sur un pourtour extérieur de la bague pour coopérer avec une surface intérieure de la lunette tournante, la bague annulaire étant destinée à être solidarisée à la carrure.According to a second embodiment of the invention, the annular ring comprises on an inner or outer periphery a set of bosses, said bosses forming said braking and sound damping means. An advantage of this second embodiment is that the bosses act radially in a plane in which the ring extends, and not perpendicularly to this plane as the tabs of the first embodiment. Thanks to the radial flexibility of the bosses, they can provide a braking of the rotation of the rotating bezel around the middle by friction against the middle part or the bezel, and a damping of the sound produced. In a first variant of this second embodiment, the bosses are arranged on an inner periphery of the ring to cooperate with a cylindrical outer surface of the middle part, the annular ring being intended to be secured to the rotating bezel. In a second variant of this second embodiment, the bosses are arranged on an outer periphery of the ring to cooperate with an inner surface of the rotating bezel, the annular ring being intended to be secured to the middle part.

Avantageusement, selon ce deuxième mode de réalisation, la bague annulaire comprend un ensemble de fentes oblongues, chaque fente oblongue étant ménagée dans l'épaisseur de la bague annulaire en regard d'un desdits bossages, l'épaisseur étant mesurée selon une direction axiale perpendiculaire à un plan dans lequel s'étend la bague. Ceci permet de conférer à chaque bossage une flexibilité radiale dans le plan dans lequel s'étend la bague.Advantageously, according to this second embodiment, the annular ring comprises a set of oblong slots, each oblong slot being formed in the thickness of the annular ring facing one of said bosses, the thickness being measured in a perpendicular axial direction. to a plane in which the ring extends. This makes it possible to confer on each boss a radial flexibility in the plane in which the ring extends.

Avantageusement encore, selon ce deuxième mode de réalisation, la bague annulaire comprend six bossages répartis sur 360°, les bossages étant espacés deux à deux de 60°. Ceci permet d'améliorer encore le freinage et l'amortissement du bruit, notamment en réduisant encore les jeux à l'intérieur du système et en rendant le couple de rotation encore plus doux.Advantageously, according to this second embodiment, the annular ring comprises six bosses distributed over 360 °, the bosses being spaced two by two by 60 °. This allows to further improve the braking and damping noise, especially by further reducing the games inside the system and making the torque even softer.

Avantageusement, la bague annulaire est formée d'une seule pièce de matière constituée d'un matériau plastique, notamment du PTFE, d'ethylene-tetrafluoroethylene (Tefzel®), et polyoxyméthylène (Delrin ®) le cas échéant revêtue d'une couche visant à améliorer le coefficient de frottement. Ce matériau a l'avantage de présenter un bon compromis souplesse / rigidité, permettant aux languettes du premier groupe de languettes et aux languettes du second groupe de languettes de présenter les propriétés élastiques et mécaniques recherchées.Advantageously, the annular ring is formed of a single piece of material made of a plastic material, in particular PTFE, ethylene-tetrafluoroethylene (Tefzel®), and polyoxymethylene (Delrin®), where appropriate coated with a protective layer. to improve the coefficient of friction. This material has the advantage of having a good compromise flexibility / rigidity, allowing the tabs of the first group of tongues and the tabs of the second group of tongues to present the desired elastic and mechanical properties.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

La figure 1 représente une montre 1 munie d'une boîte de montre 2. La boîte de montre 2 comprend typiquement une carrure 4. La boîte de montre 2 comprend également un système de lunette tournante annulaire 6 ainsi qu'un mouvement horloger qui s'étend dans un plan, le mouvement horloger n'étant pas représenté sur les figures pour des raisons de clarté. Le système de lunette tournante annulaire 6 est monté à rotation sur la carrure 4. De préférence, comme illustré sur les figures 1 à 3, le système de lunette tournante annulaire 6 est formé d'un module indépendant. Le système de lunette tournante annulaire 6 est par exemple clippé sur la carrure 4, comme cela sera détaillé par la suite.The figure 1 represents a watch 1 provided with a watch case 2. The watch case 2 typically comprises a caseband 4. The watch case 2 also comprises an annular rotating bezel system 6 as well as a watch movement which extends into a case. plan, the watch movement is not shown in the figures for the sake of clarity. The annular rotating bezel system 6 is rotatably mounted on the middle part 4. Preferably, as illustrated in FIGS. Figures 1 to 3 , the annular rotating bezel system 6 is formed of an independent module. The annular rotating bezel system 6 is for example clipped to the caseband 4, as will be detailed later.

Comme illustré sur la figure 1, la carrure 4 est de forme annulaire. La carrure 4 comprend une surface extérieure cylindrique 8. Comme visible sur la figure 3, la surface extérieure cylindrique 8 est munie d'un épaulement périphérique défini par une paroi latérale 12a et une base 12b. Cet épaulement périphérique sert de logement pour le système de lunette tournante 6. La paroi latérale 12a comprend une excroissance ou bourrelet annulaire 13 s'étendant sur l'intégralité du périmètre de la paroi latérale 12a et permettant le crochement du système de lunette tournante 6 sur la carrure 4, par clippage. Le système de lunette tournante annulaire 6 s'appuie sur la base 12b. Le système de lunette tournante 6 est ainsi monté sur la carrure 4, depuis le dessus de cette dernière, permettant un blocage du système 6 selon une direction axiale perpendiculaire au plan du mouvement horloger, tout en autorisant une rotation de la lunette autour de la carrure 4. Dans la boîte de montre 2 prise en exemple aux figures 1 à 3, la configuration de la boîte de montre est sensiblement circulaire. Toutefois, l'invention n'est nullement limitée à une telle configuration de la boîte de montre, ni aux autres dispositions décrites ci-dessus pour la carrure 4. La carrure peut être réalisée en métal, typiquement en acier, en titane, en or, en platine ou en céramique typiquement à base d'alumine, de zircone ou de nitrure de silicium.As illustrated on the figure 1 , the middle part 4 is of annular shape. The middle part 4 comprises a cylindrical outer surface 8. As visible on the figure 3 , the cylindrical outer surface 8 is provided with a peripheral shoulder defined by a side wall 12a and a base 12b. This peripheral shoulder serves as a housing for the rotating bezel system 6. The sidewall 12a comprises an annular protuberance or bead 13 extending over the entire perimeter of the sidewall 12a and allowing the rotating bezel system 6 to middle 4, by clipping. The annular rotating bezel system 6 is supported on the base 12b. The rotating bezel system 6 is thus mounted on the middle part 4, from above the latter, allowing the system 6 to be locked in an axial direction perpendicular to the plane of the watch movement, while allowing rotation of the bezel around the middle part 4. In the watch case 2 taken as an example to Figures 1 to 3 , the configuration of the watch case is substantially circular. However, the invention is not limited to such a configuration of the watch case, nor to the other arrangements described above for the middle 4. The middle part can be made of metal, typically steel, titanium, gold , platinum or ceramic typically based on alumina, zirconia or silicon nitride.

Le système de lunette tournante annulaire 6 comprend une lunette tournante 14, une bague annulaire de maintien 16, un anneau denté 18 et des moyens ressorts 20. De préférence, le système 6 comprend en outre un anneau de décor 22 engagé à force sur la lunette tournante 14. L'anneau de décor 22 porte par exemple des graduations, typiquement des graduations de plongée dans le cas d'une montre 1 de plongée. L'anneau de décor 22 est par exemple en céramique.The annular rotating bezel system 6 comprises a rotating bezel 14, an annular retaining ring 16, a toothed ring 18 and spring means 20. Preferably, the system 6 further comprises a decorative ring 22 forcibly engaged on the bezel 14. The decorative ring 22 carries for example graduations, typically dive graduations in the case of a dive watch 1. The decorative ring 22 is for example ceramic.

La lunette tournante 14 est de forme annulaire et comprend une face supérieure 23a visible par l'utilisateur et une face inférieure 23b. Comme illustré sur les figures 1 et 3, la lunette tournante 14 est par exemple munie sur un pourtour intérieur d'un rebord annulaire 24. Le rebord annulaire 24 coopère par clippage avec l'excroissance 13 de la carrure 4, et forme avec cette dernière un système de crochement libre. La lunette tournante 14 est par exemple en métal mais pourrait être réalisée en tout autre matériau par exemple en céramique.The rotating bezel 14 is annular in shape and comprises an upper face 23a visible by the user and a lower face 23b. As illustrated on figures 1 and 3 , the rotating bezel 14 is for example provided on an inner periphery of an annular flange 24. The annular flange 24 cooperates by clipping with the protrusion 13 of the middle part 4, and forms with the latter a free hooking system. The rotating bezel 14 is for example metal but could be made of any other material for example ceramic.

La bague annulaire 16 maintient l'anneau denté 18 et les moyens ressorts 20 dans la lunette 14, selon une direction axiale perpendiculaire au plan du mouvement horloger. Ceci permet de faciliter le montage de la lunette tournante 14 sur la carrure 4. De préférence, et comme visible à la figure 3, la bague annulaire 16 est chassée dans la lunette tournante 14, la solidarisant à cette dernière. Dans une variante de réalisation non représentée sur les figures, la bague annulaire 16 est solidarisée à la carrure 4.The annular ring 16 maintains the toothed ring 18 and the spring means 20 in the bezel 14, in an axial direction perpendicular to the plane of the watch movement. This facilitates the mounting of the rotating bezel 14 on the middle part 4. Preferably, and as visible in FIG. figure 3 , the annular ring 16 is driven into the rotating bezel 14, the solidarisant to the latter. In an alternative embodiment not shown in the figures, the annular ring 16 is secured to the middle part 4.

La bague annulaire 16 repose sur la base 12b de la carrure 4, et entoure ainsi la surface extérieure cylindrique 8 de la carrure 4. La bague annulaire 16 est configurée pour coopérer avec la surface extérieure cylindrique 8 pour permettre la rotation de la lunette tournante 14 sur la carrure 4.The annular ring 16 rests on the base 12b of the caseband 4, and thus surrounds the cylindrical outer surface 8 of the caseband 4. The annular ring 16 is configured to cooperate with the cylindrical outer surface 8 to allow rotation of the rotating bezel 14 on the middle 4.

Comme illustrée sur les figures 1, 4 et 5a, la bague annulaire 16 selon l'invention comprend des moyens 26 de guidage en rotation de la lunette tournante 14 autour de la carrure 4, et des moyens 28 configurés pour freiner la rotation de la lunette tournante 14 autour de la carrure 4 et pour amortir le son. La bague annulaire 16 est par exemple formée d'une seule pièce de matière constituée d'un matériau plastique, notamment du PTFE, de l'ethylene-tetrafluoroethylene (Tefzel®), ou polyoxyméthylène (Delrin ®) le cas échéant revêtue d'une couche visant à améliorer le coefficient de frottement. La bague annulaire 16 est par exemple de section générale rectangulaire.As illustrated on figures 1 , 4 and 5a , the annular ring 16 according to the invention comprises means 26 for guiding rotation of the rotating bezel 14 around the middle part 4, and means 28 configured to brake the rotation of the rotating bezel 14 around the middle part 4 and to dampen the sound. The annular ring 16 is for example formed of a single piece of material consisting of a plastic material, in particular PTFE, ethylene-tetrafluoroethylene (Tefzel®), or polyoxymethylene (Delrin®) optionally coated with a layer to improve the coefficient of friction. The annular ring 16 is for example of rectangular general section.

Dans un premier mode de réalisation représenté sur les figures 1 et 4, la bague annulaire 16 comprend sur un pourtour intérieur une alternance entre des languettes 30a d'un premier groupe de languettes, et des languettes 30b d'un second groupe de languettes. Les languettes 30a du premier groupe et les languettes 30b du second groupe sont en contact avec la surface extérieure cylindrique 8 de la carrure 4. De telles languettes 30a, 30b limitent le passage de salissures à l'intérieur du système de lunette tournante 6. Dans la variante non représentée sur les figures selon laquelle la bague annulaire 16 est solidarisée à la carrure 4, les languettes 30a du premier groupe et les languettes 30b du second groupe sont agencées sur un pourtour extérieur de la bague annulaire 16 et sont en contact avec une surface intérieure de la lunette tournante 14.In a first embodiment shown on the figures 1 and 4 , the annular ring 16 comprises on an inner periphery an alternation between tabs 30a of a first group of tongues, and tongues 30b of a second group of tongues. The tongues 30a of the first group and the tongues 30b of the second group are in contact with the cylindrical outer surface 8 of the middle part 4. Such tongues 30a, 30b limit the passage of dirt inside the rotating bezel system 6. In the variant not shown in the figures according to which the annular ring 16 is secured to the middle part 4, the tongues 30a of the first group and the tongues 30b of the second group are arranged on an outer periphery of the annular ring 16 and are in contact with an inner surface of the rotating bezel 14.

Dans l'exemple de réalisation des figures 1 et 4, les premier et second groupes de languettes comprennent chacun six languettes 30a, 30b, réparties sur le pourtour intérieur de la bague 16 sur 360°. Les languettes d'un même groupe de languettes sont ainsi espacées deux à deux de 60°, les languettes 30a, 30b des premier et second groupes de languettes étant alternées.In the exemplary embodiment of figures 1 and 4 , the first and second groups of tabs each comprise six tabs 30a, 30b distributed over the inner periphery of the ring 16 over 360 °. The tongues of the same group of tongues are thus spaced two by two by 60 °, the tongues 30a, 30b of the first and second groups of tongues being alternated.

Les languettes 30a du premier groupe et les languettes 30b du second groupe présentent des dimensions, selon la direction radiale, différenciées. Dans l'exemple de réalisation des figures 1 et 4, les languettes 30a du premier groupe de languettes présentent des dimensions selon la direction radiale inférieures à celles des languettes 30b du second groupe de languettes, et forment les moyens de guidage en rotation 26. Ainsi, comme représenté sur la figure 4, la distance radiale D1 séparant les languettes 30a du premier groupe de languettes du centre de la bague 16 est supérieure à la distance radiale D2 séparant les languettes 30b du second groupe de languettes du centre de la bague 16.The tongues 30a of the first group and the tongues 30b of the second group have dimensions, in the radial direction, differentiated. In the exemplary embodiment of figures 1 and 4 , the tongues 30a of the first group of tongues have dimensions in the radial direction less than those of the tongues 30b of the second group of tongues, and form the rotation guiding means 26. Thus, as shown in FIG. figure 4 , the radial distance D1 separating the tabs 30a of the first group of tongues from the center of the ring 16 is greater than the radial distance D2 separating the tabs 30b of the second group of tongues from the center of the ring 16.

Les languettes 30b du second groupe de languettes forment les moyens de freinage et d'amortissement du son 28. Plus précisément, les languettes 30b du second groupe de languettes sont constituées de segments plus souples que les languettes 30a du premier groupe. De tels segments sont aptes à fléchir selon une direction axiale perpendiculaire au plan du mouvement horloger. Pour ce faire, un exemple de réalisation particulier représenté aux figures 1 et 4 consiste en ce que les languettes 30a du premier groupe et les languettes 30b du second groupe présentent des épaisseurs différenciées, l'épaisseur étant mesurée selon la direction axiale perpendiculaire au plan du mouvement horloger. Typiquement, les languettes 30b du second groupe présentent une épaisseur inférieure à celle des languettes 30a du premier groupe, leur conférant ainsi une plus grande souplesse. Grâce à la flexibilité axiale des languettes 30b du second groupe, celles-ci peuvent assurer un freinage de la rotation de la lunette tournante 14 autour de la carrure 4 par frottement contre la surface extérieure cylindrique 8, ainsi qu'un amortissement du son produit.The tongues 30b of the second group of tongues form the means for braking and damping the sound 28. More specifically, the tongues 30b of the second group of tongues consist of segments that are more flexible than the tongues 30a of the first group. Such segments are able to flex in an axial direction perpendicular to the plane of the watch movement. To do this, a particular example of embodiment represented in figures 1 and 4 consists in that the tabs 30a of the first group and the tongues 30b of the second group have differentiated thicknesses, the thickness being measured in the axial direction perpendicular to the plane of the watch movement. Typically, the tongues 30b of the second group have a thickness less than that of the tongues 30a of the first group, thus giving them greater flexibility. Thanks to the axial flexibility of the tabs 30b of the second group, they can provide a braking of the rotation of the rotating bezel 14 around the middle part 4 by friction against the cylindrical outer surface 8, and a damping of the sound produced.

De préférence, les languettes 30a, 30b des premier et second groupes sont séparées les unes des autres par des échancrures 32. Ceci permet notamment d'améliorer la flexibilité des languettes 30b du second groupe de languettes.Preferably, the tabs 30a, 30b of the first and second groups are separated from each other by notches 32. This allows in particular to improve the flexibility of the tabs 30b of the second group of tongues.

De préférence encore, comme visible sur la figure 4, les languettes 30a, 30b des premier et second groupes de languettes s'étendent angulairement sur un secteur angulaire S1 sensiblement égal.More preferably, as visible on the figure 4 , the tabs 30a, 30b of the first and second groups of tongues extend angularly on a substantially equal angular sector S1.

Dans un deuxième mode de réalisation représenté sur les figures 5a et 5b, la bague annulaire 16 ne comprend plus de languettes mais comprend, sur un pourtour intérieur, un ensemble de bossages 33. Les bossages 33 sont en contact avec la surface extérieure cylindrique 8 de la carrure 4 et forment les moyens de freinage et d'amortissement du son 28. De tels bossages 33 agissent radialement dans un plan dans lequel s'étend la bague 16, et non perpendiculairement à ce plan comme les languettes 30a, 30b du premier mode de réalisation. Dans la variante non représentée sur les figures selon laquelle la bague annulaire 16 est solidarisée à la carrure 4, les bossages 33 sont agencés sur un pourtour extérieur de la bague annulaire 16 et sont en contact avec une surface intérieure de la lunette tournante 14. Dans l'exemple de réalisation illustré sur les figures 5a et 5b, les moyens de guidage en rotation 26 sont constitués du reste du pourtour intérieur de la bague 16, entre les bossages 33.In a second embodiment shown on the Figures 5a and 5b , the annular ring 16 no longer includes tabs but comprises, on an inner periphery, a set of bosses 33. The bosses 33 are in contact with the cylindrical outer surface 8 of the middle part 4 and form the braking and damping means sound 28. Such bosses 33 act radially in a plane in which the ring 16 extends, and not perpendicular to this plane as the tabs 30a, 30b of the first embodiment. In the variant not shown in the figures according to which the annular ring 16 is secured to the middle part 4, the bosses 33 are arranged on an outer periphery of the annular ring 16 and are in contact with an inner surface of the rotating bezel 14. In the exemplary embodiment illustrated on the Figures 5a and 5b , the rotation guiding means 26 consist of the rest of the inner periphery of the ring 16, between the bosses 33.

Dans l'exemple de réalisation des figures 5a et 5b, la bague 16 comprend six bossages 33, répartis sur le pourtour intérieur de la bague 16 sur 360°. Les bossages 33 sont ainsi espacés deux à deux de 60°.In the exemplary embodiment of Figures 5a and 5b , the ring 16 comprises six bosses 33, distributed around the inner periphery of the ring 16 over 360 °. The bosses 33 are thus spaced two by two by 60 °.

Afin de conférer aux bossages 33 une flexibilité radiale dans le plan dans lequel s'étend la bague 16, la bague 16 comprend de préférence un ensemble de fentes oblongues 35. Comme illustré sur les figures 5a et 5b, chaque fente oblongue 35 est ménagée dans l'épaisseur de la bague annulaire 16 en regard d'un des bossages 33. Dans l'exemple de réalisation des figures 5a et 5b, la bague 16 comprend ainsi six fentes oblongues 35, réparties sur 360°. Les fentes oblongues 35 sont ainsi espacées deux à deux de 60°.In order to give the bosses 33 radial flexibility in the plane in which the ring 16 extends, the ring 16 preferably comprises a set of oblong slots 35. As illustrated in FIGS. Figures 5a and 5b each oblong slot 35 is formed in the thickness of the annular ring 16 facing one of the bosses 33. In the example of realization of Figures 5a and 5b , the ring 16 thus comprises six oblong slots 35, distributed over 360 °. The oblong slots 35 are thus spaced two by two by 60 °.

Grâce à la flexibilité radiale des bossages 33 dans le plan dans lequel s'étend la bague 16, ceux-ci peuvent assurer un freinage de la rotation de la lunette tournante 14 autour de la carrure 4 par frottement contre la surface extérieure cylindrique 8, ainsi qu'un amortissement du son produit.Thanks to the radial flexibility of the bosses 33 in the plane in which the ring 16 extends, these can provide a braking of the rotation of the rotating bezel 14 around the middle part 4 by friction against the cylindrical outer surface 8, and that a damping of the sound produced.

Le freinage de la rotation de la lunette 14 par les moyens 28 présente l'avantage de lisser les différents jeux à l'intérieur du système de sorte que l'utilisateur de la lunette ne les ressente pas, ainsi que de maîtriser le couple de rotation de la lunette en le rendant plus doux. En outre, les moyens de freinage et d'amortissement du son 28 permettent de réduire le bruit produit par la rotation de la lunette et donc d'améliorer le ressenti utilisateur.The braking of the rotation of the telescope 14 by the means 28 has the advantage of smoothing the different games inside the system so that the user of the telescope does not feel them, as well as to control the rotation torque of the bezel by making it softer. In addition, the braking and sound damping means 28 reduce the noise produced by the rotation of the telescope and thus improve the user feeling.

L'anneau denté 18 comprend plusieurs dents, par exemple 120 dents, également réparties sur son pourtour extérieur sur 360°. De préférence, l'anneau denté 18 présente en outre, sur son pourtour intérieur, au moins un ergot 34 reçu dans une échancrure 36 prévue dans la surface extérieure cylindrique 8 de la carrure 4. Dans l'exemple de réalisation illustré sur la figure 1, l'anneau denté 18 comprend trois ergots 34 répartis sur 360° et espacés deux à deux de 120°. La surface extérieure cylindrique 8 de la carrure 4 comprend trois échancrures 36 correspondantes. Ce système ergots 34 / échancrures 36 permet une solidarisation angulaire aisée de l'anneau denté 18 à la carrure 4, tout en facilitant le positionnement de l'anneau denté 18 sur la carrure 4. Ce système permet également de guider le système de lunette tournante 6 pour son montage sur la carrure 4. Ainsi, en pressant depuis le dessus du système 6, on engage les ergots 34 dans les échancrures 36, permettant d'encliqueter les éléments à l'intérieur du système 6 et de clipper le système 6 sur la carrure 4.The toothed ring 18 comprises several teeth, for example 120 teeth, equally distributed on its outer circumference 360 °. Preferably, the toothed ring 18 further has, on its inner periphery, at least one lug 34 received in a notch 36 provided in the cylindrical outer surface 8 of the caseband 4.

L'anneau denté 18 est formé d'une seule pièce de matière. L'anneau denté 18 est par exemple constitué d'un alliage métallique, notamment un alliage à base de cobalt (40%Co, 20%Cr, 16%Ni et. 7%Mo) dénommé commercialement phynox ou de l'acier typiquement un acier inoxydable par exemple 316L. En variante, l'anneau denté 18 peut être constitué d'un matériau thermoplastique, notamment un matériau thermoplastique semi-cristallin thermostable tel que par exemple du polyarylamide (Ixef®), polyétheréthercétone (PEEK) ou encore d'un matériau céramique (zircone ou alumine).The toothed ring 18 is formed of a single piece of material. The toothed ring 18 is for example made of a metal alloy, in particular an alloy based on cobalt (40% Co, 20% Cr, 16% Ni and 7% Mo), known commercially as phynox, or steel, which is typically one. stainless steel for example 316L. As a variant, the toothed ring 18 may consist of a thermoplastic material, in particular a thermostable semi-crystalline thermoplastic material such as, for example, polyarylamide (Ixef®), polyetheretherketone (PEEK) or a ceramic material (zirconia or alumina).

Les moyens ressorts 20 coopèrent élastiquement avec l'anneau denté 18. Selon un exemple de réalisation illustré sur les figures 1 à 3, les moyens ressorts 20 sont constitués d'un anneau ressort. Comme visible à la figure 3, l'anneau denté 18 est agencé pour s'insérer dans l'anneau ressort 20, c'est-à-dire que l'anneau denté 18 est dimensionné pour pouvoir être placé dans l'anneau ressort 20. L'anneau denté 18 et l'anneau ressort 20 sont concentriques et coplanaires, et sont maintenus entre la face inférieure 23b de la lunette 14 et une face supérieure de la bague de maintien 16.The spring means 20 cooperate elastically with the toothed ring 18. According to an exemplary embodiment illustrated in FIGS. Figures 1 to 3 , the spring means 20 consist of a spring ring. As visible at figure 3 , the toothed ring 18 is arranged to fit into the spring ring 20, that is to say that the toothed ring 18 is sized to be placed in the spring ring 20. The toothed ring 18 and the spring ring 20 are concentric and coplanar, and are held between the underside 23b of the bezel 14 and an upper face of the retaining ring 16.

L'anneau ressort 20 comprend au moins une portion amincie 38 présentant au moins une dent 40 élastiquement et radialement en prise avec l'anneau denté 18. Dans l'exemple de réalisation illustré sur la figure 1, l'anneau ressort 20 comprend trois portions amincies 38 réparties sur 360°, chaque portion amincie 38 présentant une dent 40 agencée dans une partie médiane de la portion amincie 38. Les trois portions amincies 38 sont espacées deux à deux de 120°. L'anneau ressort 20 s'étend dans un plan dans lequel il est susceptible de se déformer élastiquement selon un rayon. Les portions amincies 38 sont agencées pour augmenter la flexibilité de l'anneau ressort 20 dans son plan. Cette configuration permet, lorsque l'anneau denté 18 est inséré à l'intérieur de l'anneau ressort 20, que les dents 40 coopèrent avec les dents de l'anneau denté 18. Dans cette configuration, chaque dent 40 est en contact avec l'anneau denté 18 de sorte qu'il existe une position de repos dans laquelle chaque dent 40 se trouve dans un creux entre deux dents de l'anneau denté 18. Quand l'utilisateur se saisit de la lunette 14 et la tourne, du fait de la flexibilité de l'anneau ressort 20 conférée par les portions amincies 38, l'anneau ressort 20 se déforme élastiquement dans son plan, permettant aux dents 40 de se dégager des creux de l'anneau denté 18 et de se ré-engrener dans une dent adjacente de l'anneau denté 18. La lunette 14 tourne alors effectivement d'un secteur angulaire correspondant, vers une nouvelle position.The spring ring 20 comprises at least one thinned portion 38 having at least one tooth 40 elastically and radially in engagement with the toothed ring 18. In the embodiment illustrated in FIG. figure 1 , the spring ring 20 comprises three thinned portions 38 distributed over 360 °, each thinned portion 38 having a tooth 40 arranged in a middle portion of the thinned portion 38. The three thinned portions 38 are spaced two by two by 120 °. The spring ring 20 extends in a plane in which it is capable of elastically deforming along a radius. The thinned portions 38 are arranged to increase the flexibility of the spring ring 20 in its plane. This configuration allows, when the toothed ring 18 is inserted inside the spring ring 20, that the teeth 40 cooperate with the teeth of the toothed ring 18. In this configuration, each tooth 40 is in contact with the toothed ring 18. toothed ring 18 so that there is a rest position in which each tooth 40 is located in a hollow between two teeth of the toothed ring 18. When the user grasps the bezel 14 and rotates it, because of the flexibility of the spring ring 20 conferred by the thinned portions 38, the spring ring 20 deforms elastically in its plane, allowing the teeth 40 to disengage from the hollows of the toothed ring 18 and to re-engage in an adjacent tooth of the toothed ring 18. The bezel 14 then turns effectively from a sector corresponding angle, to a new position.

De préférence, comme illustré sur la figure 1, les portions amincies 38 sont amincies radialement.Preferably, as illustrated on the figure 1 the thinned portions 38 are thinned radially.

De préférence encore, l'anneau ressort 20 présente, sur son pourtour extérieur, au moins une échancrure 42 dans laquelle un ergot de la lunette 14 est engagé. Dans l'exemple de réalisation illustré sur la figure 1, l'anneau ressort 20 comprend trois échancrures 42 réparties sur 360° et espacées deux à deux de 120°, et la lunette tournante 14 comprend sur une face latérale interne trois ergots correspondants. Les échancrures 42 sont ménagées dans des portions 46 de l'anneau ressort 20 plus épaisses que les portions amincies 38, dans des parties médianes de ces portions 46. Ainsi, les dents 40 et les échancrures 42 forment une alternance sur l'anneau ressort 20, régulièrement réparties sur 360°. Ce système ergots / échancrures 42 permet de lier facilement en rotation l'anneau ressort 20 à la lunette tournante 14, tout en facilitant le positionnement de l'anneau ressort 20 dans la lunette 14.More preferably, the spring ring 20 has, on its outer periphery, at least one notch 42 in which a lug of the bezel 14 is engaged. In the exemplary embodiment illustrated on the figure 1 , the spring ring 20 comprises three indentations 42 distributed over 360 ° and spaced two by two by 120 °, and the rotating bezel 14 comprises on an internal lateral face three corresponding lugs. The notches 42 are formed in portions 46 of the spring ring 20 thicker than the thinned portions 38, in the middle portions of these portions 46. Thus, the teeth 40 and notches 42 form an alternation on the spring ring 20 regularly distributed over 360 °. This system lugs / notches 42 makes it easy to rotate the spring ring 20 to the rotating bezel 14, while facilitating the positioning of the spring ring 20 in the bezel 14.

L'anneau ressort 20 est formé d'une seule pièce de matière. L'anneau ressort 20 est par exemple constitué d'un alliage métallique, ayant de bonnes propriétés ressort c'est-à-dire qui se déforme facilement de manière élastique tout en pouvant se déformer de manière importante sans subir de déformation plastique, notamment du phynox® ou encore d'alliages métalliques amorphes. Bien entendu, l'anneau ressort 20 peut aussi, en variante, être réalisé dans un matériau synthétique.The spring ring 20 is formed of a single piece of material.
