Description

Le domaine technique de l'invention est celui des boîtiers de montres, en particulier pour des montres prévues pour être portées au poignet ou des montres de gousset.The technical field of the invention is that of watch cases, in particular for watches intended to be worn on the wrist or pocket watches.

Les montres portées au poignet comportent généralement un boîtier plat qui est étanche, de forme le plus souvent globalement circulaire, présentant un corps recevant sur une face supérieure un verre recouvrant le cadran avec ses aiguilles, et sur la face inférieure un fond.Wristwatches generally have a flat case that is waterproof, most often generally circular in shape, with a body receiving on an upper face a glass covering the dial with its hands, and on the lower face a back.

Le boîtier comporte de chaque côté deux bras recevant entre eux une aiguille transversale, qui est engagée dans une boucle d'une partie de bracelet disposée de ce côté. Une ou plusieurs couronnes disposées sur les côtés présentent un axe radial rentrant dans le mécanisme afin de réaliser les réglages et les commandes de la montre.The case has on each side two arms receiving between them a transverse needle, which is engaged in a loop of a part of the bracelet arranged on this side. One or more crowns arranged on the sides have a radial axis entering into the mechanism in order to carry out the settings and controls of the watch.

Un type de montre connu comporte un boîtier en deux parties comprenant une capsule étanche globalement circulaire présentant un axe principal, contenant le mécanisme de la montre, comprenant sur sa face supérieure le cadran avec son verre, et une carrure formant un contour extérieur recevant la capsule, comportant de chaque côté les bras de fixation du bracelet.A known type of watch comprises a two-part case comprising a generally circular waterproof capsule having a main axis, containing the mechanism of the watch, comprising on its upper face the dial with its glass, and a caseband forming an external contour receiving the capsule, comprising on each side the arms for fixing the bracelet.

En complément la carrure peut comporter des fonctions annexes. On peut de cette manière en particulier changer la carrure en gardant la même capsule, afin d'obtenir pour un coût réduit des montres présentant des esthétiques différentes.In addition, the case middle can include additional functions. In this way, the case middle can be changed while keeping the same capsule, in order to obtain watches with different aesthetics at a reduced cost.

Suivant un mode de réalisation connu de ce type de montre, la capsule est introduite par l'avant dans un logement de la carrure, un rebord circulaire extérieur de la capsule venant en appui sur la face avant de cette carrure.According to a known embodiment of this type of watch, the capsule is introduced from the front into a housing in the caseband, an external circular rim of the capsule coming to bear on the front face of this caseband.

Une lunette formant un anneau circulaire présentant un filetage intérieur, est ensuite vissée sur un filetage correspondant formé à l'arrière de la capsule, afin de réaliser un serrage axial de la carrure qui est prise entre le rebord extérieur avant et la lunette.A bezel forming a circular ring with an internal thread is then screwed onto a corresponding thread formed at the rear of the capsule, in order to achieve axial tightening of the caseband which is taken between the front external rim and the bezel.

Ce système de montage est simple et économique à réaliser, en présentant une fixation solide. Toutefois il pose des problèmes. En particulier la lunette vissée sur la capsule doit être circulaire pour permettre le vissage, ce qui limite la créativité de formes différentes. De plus la lunette peut se dévisser, et tomber sans que l'utilisateur ne s'en aperçoive. Par ailleurs la lunette représente un composant mince qui peut facilement se voiler ou se visser de travers sur le filetage de la capsule, ce qui fausse le pas-de-vis de cette capsule représentant l'élément le plus cher.This mounting system is simple and economical to make, with a solid attachment. However, it poses problems. In particular, the bezel screwed onto the capsule must be circular to allow screwing, which limits the creativity of different shapes. In addition, the bezel can unscrew and fall without the user noticing. In addition, the bezel represents a thin component that can easily warp or screw crooked onto the capsule thread, which distorts the thread of this capsule representing the most expensive element.

Suivant un autre mode de réalisation connu de ce type de montre la capsule comprenant à l'avant un rebord extérieur, est introduite par l'avant dans la carrure qui présente un couvercle fixé à cette carrure par un pivot latéral, formant un anneau venant recouvrir le contour de la capsule pour la maintenir en place.According to another known embodiment of this type of watch, the capsule comprising an external rim at the front is introduced from the front into the caseband which has a cover fixed to this caseband by a lateral pivot, forming a ring covering the outline of the capsule to hold it in place.

Le verrouillage du couvercle sur la carrure en pressant sur le contour de la capsule, se fait ensuite par un système de crochets poussés par un ressort, qui viennent s'accrocher automatiquement quand ce couvercle est fermé sur la carrure.The cover is then locked onto the case by pressing on the contour of the capsule, using a system of hooks pushed by a spring, which automatically engage when the cover is closed on the case.

On obtient une carrure présentant un aspect technique et inventif, qui peut correspondre à l'image donnée par certaines marques de montres.The result is a case with a technical and inventive appearance, which can correspond to the image given by certain watch brands.

Toutefois ce système de montage est relativement fragile à cause du nombre de pièces nécessaire pour le verrouillage du couvercle, la tenue dans le temps est incertaine. En particulier la fiabilité dans le cas d'un usage sportif présentant des contraintes mécaniques qui peuvent être fortes, risque d'être limitée.However, this assembly system is relatively fragile because of the number of parts required to lock the cover, and its durability is uncertain. In particular, reliability in the case of sports use with potentially high mechanical constraints may be limited.

Suivant un autre mode de réalisation connu de ce type de montre, la capsule est insérée dans le logement de la carrure par l'avant, et bloquée par des billes poussées par des ressorts qui s'ajustent dans des creux correspondants formés sur le contour de la capsule afin d'assurer son maintien axial.According to another known embodiment of this type of watch, the capsule is inserted into the housing of the caseband from the front, and blocked by balls pushed by springs which fit into corresponding hollows formed on the contour of the capsule in order to ensure its axial support.

Une couronne supplémentaire disposée latéralement, traverse la carrure pour se visser dans la capsule afin d'assurer un verrouillage complet de cette capsule.An additional crown arranged laterally, crosses the caseband to screw into the capsule in order to ensure complete locking of this capsule.

Ce type de verrouillage est simple à réaliser, toutefois la fiabilité à long terme n'est pas assurée. En particulier les ressorts pressant les billes peuvent s'oxyder, ce qui limiterait la durée de vie de la carrure. De plus il faut prévoir un volume pour loger le moyen de blocage à billes, qui impose des contraintes esthétiques sur la carrure.This type of locking is simple to achieve, however long-term reliability is not guaranteed. In particular, the springs pressing the balls can oxidize, which would limit the service life of the caseband. In addition, a volume must be provided to house the ball locking means, which imposes aesthetic constraints on the caseband.

Le document EP2874022B1 divulgue une boîte de montre comportant une carrure, dont la paroi interne comporte des ergots, ainsi qu'un fond comportant des languettes configurées pour coopérer avec les ergots pour la réalisation d'une liaison à baïonnette.The document EP2874022B1 discloses a watch case comprising a caseband, the internal wall of which comprises lugs, as well as a back comprising tabs configured to cooperate with the lugs to produce a bayonet connection.

La présente invention a notamment pour but d'éviter ces inconvénients de la technique antérieure.The present invention aims in particular to avoid these drawbacks of the prior art.

Elle propose à cet effet un boîtier de montre tel que défini dans la revendication indépendante 1 annexée.For this purpose, it provides a watch case as defined in the attached independent claim 1.

Un avantage de ce boîtier de montre est qu'après avoir introduit la capsule avec la lunette mise en place sur la face arrière dans la carrure, les languettes étant insérées entre la capsule et le logement de la carrure, on peut notamment par une rotation de la lunette déplacer les languettes sur des pentes réalisées sur le contour extérieur de la capsule, et de manière simple écarter radialement ces languettes pour les introduire dans une ou plusieurs gorges présentant une orientation circulaire du logement de la carrure.An advantage of this watch case is that after having inserted the capsule with the bezel placed on the rear face into the caseband, the tabs being inserted between the capsule and the housing of the caseband, it is possible in particular by rotating the bezel to move the tabs on slopes made on the external contour of the capsule, and in a simple manner to spread these tabs radially to introduce them into one or more grooves having a circular orientation of the housing of the caseband.

Les languettes bloquées axialement dans la ou les gorges à orientation circulaire, ne pouvant coulisser vers l'arrière, on obtient de manière économique un maintien efficace et solide de la lunette et de la capsule dans la carrure. De plus les languettes insérées dans l'interstice entre la capsule et la carrure ne sont pas visibles, ce qui donne un aspect esthétique soigné.The tabs are axially locked in the circularly oriented groove(s), and cannot slide backwards, thus providing an efficient and solid hold for the bezel and capsule in the caseband. In addition, the tabs inserted in the gap between the capsule and the caseband are not visible, which gives a neat aesthetic appearance.

Le boîtier de montre selon l'invention peut comporter de plus une ou plusieurs des caractéristiques suivantes, qui peuvent être combinées entre elles.The watch case according to the invention may further comprise one or more of the following features, which may be combined with each other.

Avantageusement le boîtier de montre comporte par rapport à l'axe une position angulaire d'assemblage de la capsule et de la lunette par un coulissement axial dans le logement de la carrure, et une position angulaire différente de blocage de la lunette dans laquelle les languettes sont en partie insérées dans la ou les gorges circulaires.Advantageously, the watch case comprises, relative to the axis, an angular position for assembling the capsule and the bezel by axial sliding in the housing of the caseband, and a different angular position for blocking the bezel in which the tabs are partly inserted into the circular groove(s).

Avantageusement, le contour extérieur de la capsule comporte des rainures recevant les languettes, présentant un fond en pente dans la direction circonférentielle. On réalise de manière simple par la rotation de la lunette, une insertion des languettes dans la ou les gorges de la carrure par leur glissement sur la pente.Advantageously, the outer contour of the capsule comprises grooves receiving the tabs, having a sloping bottom in the circumferential direction. The tabs are simply inserted into the groove(s) of the caseband by sliding them on the slope by rotating the bezel.

Avantageusement, la lunette présente sur son contour des marquages indiquant les positions angulaires d'assemblage et de blocage. On peut de cette manière assurer la bonne position de blocage de la lunette.Advantageously, the bezel has markings on its outline indicating the angular assembly and locking positions. In this way, the correct locking position of the bezel can be ensured.

En particulier, les languettes peuvent présenter en partant du contour circulaire de la lunette, une partie axiale, puis une partie circonférentielle prévue pour s'insérer dans une gorge circulaire. De cette manière on donne une élasticité radiale à la partie circonférentielle.In particular, the tabs may have, starting from the circular contour of the bezel, an axial part, then a circumferential part intended to fit into a circular groove. In this way, radial elasticity is given to the circumferential part.

En particulier, la lunette peut comporter vers l'arrière un contour circulaire qui est intégré dans une marche réalisée autour de la face arrière de la capsule. Le contour circulaire est alors intégré dans l'épaisseur de la capsule.In particular, the bezel may have a circular contour towards the rear which is integrated into a step made around the rear face of the capsule. The circular contour is then integrated into the thickness of the capsule.

Dans ce cas, le contour circulaire de la lunette peut présenter une forme conique qui s'ajuste sur une forme correspondante au fond de la marche de la face arrière de la capsule.In this case, the circular outline of the bezel may have a conical shape that fits onto a corresponding shape at the bottom of the step of the rear face of the capsule.

Avantageusement, la lunette présente sur son contour des formes en relief.Advantageously, the bezel has raised shapes on its outline.

Avantageusement, la carrure comporte une forme de blocage en rotation de la capsule. On peut de cette manière tourner facilement la lunette sans risquer d'entraîner la capsule en rotation.Advantageously, the case includes a form of rotation lock for the capsule. In this way, the bezel can be easily turned without risking the capsule rotating.

Dans ce cas, la forme de blocage en rotation est avantageusement une fente radiale recevant un tube entourant l'axe d'une couronne de réglage la capsule.In this case, the rotational locking form is advantageously a radial slot receiving a tube surrounding the axis of a capsule adjustment crown.

Pour plus de clarté, les éléments identiques ou similaires sont repérés par des signes de référence identiques sur l'ensemble des figures.For clarity, identical or similar elements are identified by identical reference symbols throughout the figures.

Les figures 1 et 2 présentent un boitier de montre selon un premier mode de réalisation, et en particulier une carrure 2 comprenant un logement cylindrique 4 ouvert vers le côté arrière, indiqué par la flèche « AR », recevant de manière ajustée le contour extérieur cylindrique 22 d'une capsule 20. Ce contour extérieur 22 de la capsule 20 peut alternativement prendre une autre forme que celle cylindrique ici illustrée.THE figures 1 And 2 present a watch case according to a first embodiment, and in particular a caseband 2 comprising a cylindrical housing 4 open towards the rear side, indicated by the arrow “AR”, receiving in a fitted manner the cylindrical outer contour 22 of a capsule 20. This outer contour 22 of the capsule 20 can alternatively take a shape other than the cylindrical one illustrated here.

Le logement 4 de la carrure 2 se termine vers l'avant par un rebord circulaire 6 dépassant légèrement vers l'intérieur de ce logement, formant un appui du contour avant de la capsule 20.The housing 4 of the middle 2 ends towards the front with a circular rim 6 projecting slightly towards the inside of this housing, forming a support for the front contour of the capsule 20.

La carrure 2 comporte de chaque côté deux cornes 8 sensiblement parallèles, présentant chacun un perçage 10 en regard l'un de l'autre, recevant une aiguille non représentée, aussi appelée pompe, venant se loger dans une boucle d'une partie de bracelet.The middle 2 has on each side two substantially parallel horns 8, each having a hole 10 facing one another, receiving a needle not shown, also called a pump, which is housed in a buckle of part of the bracelet.

Un côté de la carrure 2 comporte une fente orientée radialement 12, qui débouche vers l'arrière, recevant de manière ajustée un tube 24 entourant la tige d'une couronne 26 de la capsule 20, qui est vissé ou chassé dans cette capsule. L'ensemble formé par le tube 24 et la couronne 26 constitue une molette de réglage du mécanisme d'horlogerie intégré dans la capsule 20.One side of the case 2 has a radially oriented slot 12, which opens towards the rear, receiving in a fitted manner a tube 24 surrounding the stem of a crown 26 of the capsule 20, which is screwed or driven into this capsule. The assembly formed by the tube 24 and the crown 26 constitutes a wheel for adjusting the clockwork mechanism integrated in the capsule 20.

La carrure 2 comporte sur le contour de son logement 4 une gorge intérieure circulaire continue 14 décalée de l'extrémité arrière de ce logement. En variante la gorge 14 peut être discontinue, présentant seulement des parties circulaires distinctes.The case 2 has on the outline of its housing 4 a continuous circular internal groove 14 offset from the rear end of this housing. Alternatively, the groove 14 may be discontinuous, having only distinct circular parts.

La capsule 20 présente une face arrière plate 28, comportant un contour légèrement conique qui est décalé vers l'avant de manière à former une petite marche autour de cette face arrière plate.The capsule 20 has a flat rear face 28, comprising a slightly conical contour which is offset forward so as to form a small step around this flat rear face.

Une lunette 30 comporte un contour circulaire légèrement conique s'ajustant sur le contour conique de la capsule 20, de manière à s'intégrer dans la marche autour de la face arrière plate 28, en s'ajustant au niveau de cette face arrière. La lunette 30 peut être réalisée dans une tôle découpée, ou dans tout autre matériau, comme un matériau composite par exemple.A bezel 30 has a slightly conical circular contour fitting over the conical contour of the capsule 20, so as to fit into the step around the flat rear face 28, fitting at the level of this rear face. The bezel 30 may be made of a cut sheet metal, or of any other material, such as a composite material for example.

Le contour de la lunette 30 comporte une série de reliefs 32 disposés radialement, répartis angulairement, qui constituent des moyens d'accrochage permettant avec la main d'entraîner en rotation cette lunette.The outline of the bezel 30 includes a series of reliefs 32 arranged radially, distributed angularly, which constitute attachment means allowing this bezel to be rotated by hand.

La face arrière de la carrure 2 présente un repère radial 60 qui peut être disposé en face d'un bossage entre deux creux 32 de la lunette 30, présentant un marquage indiquant la position « OPEN » de déverrouillage 62 ou « CLOSE » de verrouillage 64. Bien entenu, ce marquage peut être différent de ce mode de réalisation et n'est pas limité à la gravure des positions. Par exemple une telle gravure peut être remplacée par un ou plusieurs symbole(s) ou tout autre marquage convenant à une telle utilisation, à savoire pour indiquer le statut du verouillage.The rear face of the caseband 2 has a radial mark 60 which can be arranged opposite a boss between two recesses 32 of the bezel 30, having a marking indicating the unlocking “OPEN” position 62 or the locking “CLOSE” position 64. Of course, this marking can be different from this embodiment and is not limited to the engraving of the positions. For example, such an engraving can be replaced by one or more symbols or any other marking suitable for such use, namely to indicate the locking status.

La figure 3 présente la lunette 30 comportant sur l'extérieur de son contour plusieurs languettes 34 réparties angulairement, tournées vers l'avant, de forme globalement cylindrique, comprenant pour chacune successivement en partant de ce contour une partie axiale, et une partie circonférentielle 38 comprenant à son extrémité un petit bossage 40 tourné vers l'axe. Les languettes 34 sont prévues pour s'ajuster dans le logement cylindrique 4 de la carrure 2, en coulissant axialement à partir du côté arrière.There figure 3 presents the bezel 30 comprising on the outside of its contour several tongues 34 distributed angularly, facing forward, of generally cylindrical shape, comprising for each successively starting from this contour an axial part, and a circumferential part 38 comprising at its end a small boss 40 facing the axis. The tongues 34 are provided to fit into the cylindrical housing 4 of the caseband 2, by sliding axially from the rear side.

Les figures 4 et 5 présentent la capsule 20 comportant sur son contour extérieur cylindrique 22 plusieurs rainures extérieures 50, au nombre de trois dans ce mode de réalisation, réparties angulairement, comprenant chacune une première partie axiale 52 débouchant vers l'arrière. En variante on peut prévoir un nombre différent de rainures extérieures 50 et de languettes 34.THE figures 4 And 5 present the capsule 20 comprising on its cylindrical outer contour 22 several outer grooves 50, three in number in this embodiment, distributed angularly, each comprising a first axial part 52 opening towards the rear. As a variant, a different number of outer grooves 50 and tabs 34 can be provided.

La première partie 52 de chaque rainure extérieure 50 peut recevoir entièrement dans l'épaisseur une languette 34, qui se trouve dans une position d'assemblage comme présenté figures 4 et 6.The first part 52 of each external groove 50 can receive entirely in the thickness a tab 34, which is in an assembly position as shown. figures 4 And 6 .

Pour chaque rainure 50 la première partie axiale 52 se prolonge par une deuxième partie circonférentielle 54 éloignée de la face arrière de la capsule 20, qui présente un fond remontant progressivement radialement vers l'extérieur en formant une pente. Ce fond dispose d'un creux 41, par exemple formé par de rainures et/ou de stries, afin de pouvoir y loger le bossage 40 en position assemblée de la lunette 30, après sa rotation de verrouillage. De cette manière un tel bossage 40 en combinaison avec un tel creux 41 forme un moyen de sécurisation en rotation permettant de verrouiller la position assemblée de la lunette 30 par rapport à la capsule 20 de sorte que, pour effectuer le mouvement inverse, à savoir une rotation de déverrouillage de la lunette 30 par rapport à la capsule 20, il est nécessaire de passer un cran d'arrêt nécessitant un effort prédéterminé, ceci par mesure de sécurité pour s'assurer que la lunette 30 ne peux pas pivoter par simples frottements et/ou vibrations, lorsque la montre est maintenue sur le poignet d'un utilisateur.For each groove 50, the first axial portion 52 is extended by a second circumferential portion 54 remote from the rear face of the capsule 20, which has a bottom gradually rising radially outwards, forming a slope. This bottom has a hollow 41, for example formed by grooves and/or grooves, in order to be able to house the boss 40 in the assembled position of the bezel 30, after its locking rotation. In this way, such a boss 40 in combination with such a hollow 41 forms a rotation securing means for locking the assembled position of the bezel 30 relative to the capsule 20 so that, to perform the reverse movement, namely an unlocking rotation of the bezel 30 relative to the capsule 20, it is necessary to pass a stop notch requiring a predetermined effort, this as a safety measure to ensure that the bezel 30 cannot pivot by simple friction and/or vibrations, when the watch is held on a user's wrist.

L'assemblage du boîtier de montre est réalisé de la manière suivante. Dans une première étape la lunette 30 est mise en place en l'ajustant sur l'arrière de la capsule 20, chaque languette 34 rentrant entièrement dans la première partie 52 axiale d'une rainure 50.The assembly of the watch case is carried out in the following manner. In a first step, the bezel 30 is put in place by adjusting it on the rear of the capsule 20, each tab 34 entering entirely into the first axial part 52 of a groove 50.

La capsule 20 avec sa lunette 30 est ensuite insérée dans le logement 4 de la carrure 2. Le tube 24 de la couronne 26 est placé en face de la fente 12 de la carrure 2, pour rentrer dans cette fente. Le marquage « OPEN » 62 se trouve en face du repère radial 60.The capsule 20 with its bezel 30 is then inserted into the housing 4 of the caseband 2. The tube 24 of the crown 26 is placed opposite the slot 12 of the caseband 2, to fit into this slot. The “OPEN” marking 62 is opposite the radial mark 60.

On réalise dans une étape suivante à la main en s'aidant des reliefs 32 de la lunette 30, une rotation de cette lunette dans le sens horaire afin de disposer le marquage « CLOSE » 64 en face du repère radial 60, comme présenté figures 5 et 7.In a following step, we carry out by hand, using the reliefs 32 of the bezel 30, a rotation of this bezel in the clockwise direction in order to place the “CLOSE” marking 64 opposite the radial mark 60, as shown Figures 5 and 7 .

On obtient pour chaque languette 34 un engagement de sa partie circulaire 38 dans la deuxième partie 54 de la rainure correspondante 50, ainsi qu'un soulèvement vers l'extérieur de cette partie circonférentielle à cause du bossage 40 prenant appui sur la pente du fond de cette deuxième partie qui remonte. Le bossage 40 constitue un appui sur la pente de la rainure 50 présentant une surface réduite, ce qui diminue les frottements lors de la rotation de la lunette 30.For each tab 34, an engagement of its circular part 38 in the second part 54 of the corresponding groove 50 is obtained, as well as an outward lifting of this circumferential part because of the boss 40 bearing on the slope of the bottom of this second part which rises. The boss 40 constitutes a support on the slope of the groove 50 having a reduced surface, which reduces the friction during the rotation of the bezel 30.

La partie circonférentielle 38 de chaque languette 34 rentre dans la gorge circulaire 14 du logement 4 de la carrure 2 par un mouvement radial vers l'extérieur, en venant à la fin de la rotation se bloquer au fond de cette gorge. La rotation suffisante de la lunette 30 est assurée par le marquage « CLOSE » 64 venant en face du trait radial 60, garantissant le blocage des languettes 34 qui sont serrées entre le fond de la rainure 50 et celui de la gorge circulaire 14.The circumferential part 38 of each tab 34 enters the circular groove 14 of the housing 4 of the caseband 2 by a radial movement towards the outside, coming at the end of the rotation to block at the bottom of this groove. The sufficient rotation of the bezel 30 is ensured by the marking “CLOSE” 64 coming opposite the radial line 60, guaranteeing the blocking of the tabs 34 which are clamped between the bottom of the groove 50 and that of the circular groove 14.

Durant ce mouvement de rotation de la lunette 30 la capsule 20 est maintenue fixe par rapport à la carrure 2, notamment grâce au tube 24 de la couronne 26 solidaire de la capsule 20, qui est ajusté dans la fente 12 de cette carrure. Cela facilite le pivotement de la lunette 30 par rapport à la capsule 20, et donc le déplacement des languettes 34 dans les rainures 50.During this rotational movement of the bezel 30, the capsule 20 is kept fixed relative to the caseband 2, in particular thanks to the tube 24 of the crown 26 secured to the capsule 20, which is adjusted in the slot 12 of this caseband. This facilitates the pivoting of the bezel 30 relative to the capsule 20, and therefore the movement of the tabs 34 in the grooves 50.

La lunette 30 ainsi que la capsule 20 sont de cette manière efficacement bloquées dans la carrure 2, avec peu de risque de démontage, d'usure ou de défaillance dans le temps.The bezel 30 as well as the capsule 20 are in this way effectively blocked in the case 2, with little risk of disassembly, wear or failure over time.

D'une manière générale le blocage de la capsule 20 en rotation autour de son axe par rapport à la carrure 2, est assuré par le tube 24 de la molette de réglage solidaire de la capsule 20, engagé de manière ajustée dans la fente 12 de cette carrure. Le blocage en translation de la capsule 20 suivant l'axe, est assuré par l'engagement des languettes 34 dans la gorge circulaire 14 de la carrure 2. La lunette 30 est quant à elle maintenue en appui sur l'arrière de la capsule 20, la bloquant ainsi dans le logement 4 de la carrure 2.In general, the blocking of the capsule 20 in rotation about its axis relative to the caseband 2 is ensured by the tube 24 of the adjustment wheel integral with the capsule 20, engaged in a fitted manner in the slot 12 of this caseband. The blocking in translation of the capsule 20 along the axis is ensured by the engagement of the tabs 34 in the circular groove 14 of the caseband 2. The bezel 30 is for its part held in abutment on the rear of the capsule 20, thus blocking it in the housing 4 of the caseband 2.

Les figures 8 à 14 illustrent un boitier de montre selon un second mode de réalisation. En particulier, ce second mode de réalisation diffère du premier essentiellement en ce que le moyen de sécurisation en rotation est formé non plus par le bossage 40 venant se loger en position assemblée après sa rotation de verrouillage dans un creux 41 correspondant, mais par une échancrure 40' disposée sur la partie circonférentielle 38 de chaque languette 34 et dans laquelle vient se loger, en position assemblée après sa rotation de verrouillage, une saillie 41' correspondante.THE Figures 8 to 14 illustrate a watch case according to a second embodiment. In particular, this second embodiment differs from the first essentially in that the rotation securing means is no longer formed by the boss 40 which is housed in the assembled position after its locking rotation in a corresponding hollow 41, but by a notch 40' arranged on the circumferential part 38 of each tab 34 and in which is housed, in the assembled position after its locking rotation, a corresponding projection 41'.

Un tel dispositif de sécurisation en rotation permet de verrouiller la position assemblée de la lunette 30 par rapport à la capsule 20 de sorte que, pour effectuer le mouvement inverse, à savoir le pivotement de la lunette 30 par rapport à la capsule 20 dans le sens d'un déverrouillage pour ouvrir le boitier, il est nécessaire de passer un cran d'arrêt assurant la sécurité de l'assemblage et évitant toute rotation inopinée de la lunette 30.On notera que dans le cas de l'échancrure 40', le cran d'arrêt est disposé selon un axe sensiblement parallèle à l'axe de la capsule 20 tandis que dans le cas du bossage 40, ce cran d'arrêt est sensiblement radial à cedit axe du fait que l'échancrure est orientée sensiblement axialement par rapport à l'axe principal.Such a rotation securing device makes it possible to lock the assembled position of the bezel 30 relative to the capsule 20 so that, to perform the reverse movement, namely the pivoting of the bezel 30 relative to the capsule 20 in the direction of unlocking to open the case, it is necessary to pass a stop notch ensuring the safety of the assembly and preventing any unexpected rotation of the bezel 30. It will be noted that in the case of the notch 40', the stop notch is arranged along an axis substantially parallel to the axis of the capsule 20 while in the case of the boss 40, this stop notch is substantially radial to said axis because the notch is oriented substantially axially relative to the main axis.

L'invention est décrite dans ce qui précède à titre d'exemple. Il est entendu que l'homme du métier est à même de réaliser différentes variantes de réalisation de l'invention sans pour autant sortir du cadre de l'invention telle que définie dans les revendications annexées.The invention is described in the foregoing by way of example. It is understood that a person skilled in the art is able to carry out different variant embodiments of the invention without departing from the scope of the invention as defined in the appended claims.
