Description

BOITIER DE MONTRE COMPORTANT UNE CAPSULE MAINTENUE DANS UNE CARRURE CASE FOR WATCH COMPRISING A CAPSULE HELD IN A CARRIDE

PAR UNE LUNETTE ARRIERE BY AN REAR WINDOW

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.  The watches worn on the wrist generally comprise a flat casing which is waterproof, usually of generally circular shape, having a body receiving on an upper face a glass covering the dial with its hands, and on the underside a bottom.

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 housing comprises on each side two arms receiving between them a transverse needle, which is engaged in a loop of a bracelet portion disposed on this side. One or more crowns arranged on the sides have a radial axis entering the mechanism to make adjustments 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 housing comprising a generally circular sealed capsule having a main axis, containing the mechanism of the watch, comprising on its upper face the dial with its glass, and a middle part forming an outer contour receiving the capsule , comprising on each side the attachment arms of 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 middle part can include additional functions. In this way, it is possible in particular to change the middle part keeping the same capsule, in order to obtain for a reduced cost watches with different aesthetics.

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 an embodiment known from this type of watch, the capsule is introduced from the front into a housing of the middle part, an outer circular rim of the capsule bearing on the front face of this middle part.

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 having an internal thread, is then screwed on a corresponding thread formed at the rear of the capsule, to achieve an axial clamping of the middle part which is taken between the outer outer edge 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 achieve, having a solid attachment. However it poses problems. In particular the bezel screwed to the capsule must be circular to allow screwing, which limits the creativity of different shapes. In addition the bezel can unscrew itself, and fall without that the user does not notice. Furthermore the bezel is a thin component that can easily be veiled or screwed sideways on the thread of the capsule, which distorts the not-vis 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 outer rim at the front, is introduced from the front into the middle part which has a lid attached to this middle part by a lateral pivot, forming a ring to cover 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 locking of the lid on the middle part by pressing on the contour of the capsule, is then by a system of hooks pushed by a spring, which are hooked automatically when the lid is closed on the middle part.

On obtient une carrure présentant un aspect technique et inventif, qui peut correspondre à l'image donnée par certaines marques de montres.  We obtain a middle part presenting a technical and inventive aspect, which can correspond to the image given by certain brands of watches.

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 mounting system is relatively fragile because of the number of parts required for locking the cover, the behavior in time is uncertain. In particular the reliability in the case of a sporting use with mechanical stresses that can be strong, 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 recesses formed on the contour of the case. the capsule to ensure its axial retention.

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 disposed laterally through the middle to screw into the capsule to ensure complete locking of the 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 perform, however long-term reliability is not assured. In particular the springs pressing balls can oxidize, which would limit the life of the middle part. In addition it is necessary to provide a volume to accommodate the ball lock means, which imposes aesthetic constraints on the middle part.

La présente invention a notamment pour but d'éviter ces inconvénients de la technique antérieure.  The present invention is intended to avoid these disadvantages of the prior art.

Elle propose à cet effet un boîtier de montre comportant une capsule recevant le mécanisme de la montre, disposée suivant un axe principal comprenant un côté avant présentant le cadran de la montre, et comportant une carrure entourant cette capsule disposant d'un logement globalement cylindrique ouvert vers l'arrière recevant de ce côté la capsule, ce boîtier étant remarquable en ce qu'il comporte une lunette venant en appui sur l'arrière de la capsule, comprenant des languettes disposées sur le contour extérieur de la capsule, qui sont dans une position de blocage en partie insérées à l'intérieur d'au moins une gorge présentant une orientation circulaire, réalisée dans la partie cylindrique du logement de la carrure. It proposes for this purpose a watch case comprising a capsule receiving the mechanism of the watch, arranged along a main axis comprising a front side having the dial of the watch, and having a middle part surrounding the capsule having a generally cylindrical housing open rearward receiving on this side the capsule, this housing being remarkable in that it comprises a telescope bearing on the back of the capsule, comprising tabs disposed on the outer contour of the capsule, which are in a blocking position partially inserted inside at least one groove having a circular orientation, made in the cylindrical portion of the housing of the middle part.

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 introduced the capsule with the bezel placed on the rear face in the middle part, the tabs being inserted between the capsule and the housing of the middle part, it is possible in particular by a rotation of the bezel moving the tongues on slopes made on the outer contour of the capsule, and in a simple manner radially spreading these tongues to introduce them into one or more grooves having a circular orientation of the housing of the middle part.

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 tongues locked axially in the groove or grooves with a circular orientation, which can not slide backwards, economically obtain an effective and solid support of the bezel and the capsule in the caseband. In addition the tabs inserted into the gap between the capsule and the middle part 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 one another.

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, with respect to the axis, an angular position of assembly of the capsule and the bezel by axial sliding in the housing of the middle part, and a different angular position of locking of the bezel in which the tongues are partly inserted in 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 tongues, having a bottom slope in the circumferential direction. It is simple to achieve by the rotation of the telescope, an insertion of the tongues in the groove or grooves of the middle by their sliding on the slope.

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 on its contour markings indicating the angular positions of assembly and locking. In this way it is possible to ensure the correct locking position of the telescope.

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 tongues may have, starting from the circular contour of the bezel, an axial portion and then a circumferential portion intended to fit into a circular groove. In this way a 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. 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 particular, the telescope may comprise a circular outline that is integrated in a step made around the rear face of the capsule. The circular contour is then integrated in the thickness of the capsule. In this case, the circular contour of the bezel may have a conical shape that fits on 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 on its contour forms in relief.

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 middle part comprises a form of locking in rotation of the capsule. In this way it is possible to turn the bezel easily without running the risk of driving the capsule in rotation.

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 crown of adjustment the capsule.

L'invention a aussi pour objet une carrure de montre adaptée pour recevoir dans un logement globalement cylindrique ouvert vers l'arrière une capsule contenant le mécanisme de la montre, maintenue par une lunette venant en appui sur l'arrière de la capsule, comprenant des languettes disposées sur le contour extérieur de cette capsule, cette carrure comportant dans la partie cylindrique de son logement au moins une gorge présentant une orientation circulaire, prévue pour dans une position de blocage, recevoir en partie les languettes.  The subject of the invention is also a watch middle adapted to receive in a generally cylindrical housing open towards the rear a capsule containing the mechanism of the watch, held by a telescope bearing on the rear of the capsule, comprising tongues arranged on the outer contour of the capsule, this case having in the cylindrical portion of its housing at least one groove having a circular orientation, provided for a locking position, partially receive the tabs.

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

Les figures 1 et 2 présentent un boîtier 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.  FIGS. 1 and 2 show a watch case according to a first embodiment, and in particular a middle part 2 comprising a cylindrical housing 4 open towards the rear side, indicated by the arrow "AR", receiving in an adjusted manner the cylindrical outer contour 22 of a capsule 20. This outer contour 22 of the capsule 20 may alternatively take a shape other than that cylindrical 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 caseband 2 terminates forwards by a circular rim 6 projecting slightly inwardly of this housing, forming a support of 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 caseband 2 comprises on each side two horns 8 substantially parallel, each having a bore 10 opposite one another, receiving a needle not shown, also called pump, housed in a loop of a bracelet part .

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 middle part 2 has a radially oriented slot 12, which opens out towards the rear, fittingly receiving a tube 24 surrounding the stem of a ring 26 of the capsule 20, which is screwed or driven into this capsule. The assembly formed by the tube 24 and the ring 26 constitutes a control wheel of 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 middle part 2 has on the contour of its housing 4 a continuous circular inner groove 14 offset from the rear end of this housing. Alternatively the groove 14 may be discontinuous, having only separate 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, having a slightly conical contour which is shifted 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 on the conical contour of the capsule 20, so as to integrate into the walk around the flat rear face 28, adjusting at this rear face. The bezel 30 may be made in a cut sheet, or in 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 contour of the telescope 30 comprises a series of radially arranged reliefs 32, angularly distributed, which constitute hooking means allowing the hand to rotate this bezel.

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 in front of a boss between two recesses 32 of the telescope 30, having a marking indicating the "OPEN" unlocking position 62 or the "CLOSE" locking position. Of course, this marking may be different from this embodiment and is not limited to etching the positions. For example such an engraving can be replaced by one or more symbol (s) or any other marking suitable for such use, savoire to indicate the status of the lock.

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.  3 shows the telescope 30 having on the outside of its outline a plurality of tongues 34 distributed angularly, facing forward, of generally cylindrical shape, each comprising successively starting from this contour an axial portion, and a circumferential portion 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 middle part 2, 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.  Figures 4 and 5 show the capsule 20 having on its cylindrical outer contour 22 a plurality of outer grooves 50, three in number in this embodiment, angularly distributed, each comprising a first axial portion 52 opening towards the rear. Alternatively a different number of outer grooves 50 and tongues 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 portion 52 of each outer groove 50 can receive fully in the thickness a tongue 34, which is in an assembly position as shown in 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 progressively rising radially outwardly forming a slope. This bottom has a hollow 41, for example formed by grooves and / or ridges, in order to accommodate 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 telescope 30 relative to the capsule 20 so that that, to perform the reverse movement, namely an unlocking rotation of the telescope 30 relative to the capsule 20, it is necessary to pass a detent requiring a predetermined effort, this as a safety measure to ensure that the bezel 30 can not rotate by simple friction and / or vibration, when the watch is held on the wrist of a user.

L'assemblage du boîtier de montre est réalisé de la manière suivante. The assembly of the watch case is carried out as follows.

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. In a first step, the telescope 30 is put in place by fitting it on the back of the capsule 20, each tongue 34 entirely falling into the first axial portion 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 telescope 30 is then inserted into the housing 4 of the caseband 2. The tube 24 of the ring 26 is placed opposite the slot 12 of the caseband 2, to enter this slot. The marking "OPEN" 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, the hand is made with the aid of the reliefs 32 of the telescope 30, a rotation of this telescope clockwise in order to have the marking "CLOSE" 64 opposite the radial mark 60, as shown in FIGS. 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 For each tongue 34 is obtained an engagement of its circular portion 38 in the second portion 54 of the corresponding groove 50, and an upward lifting of this circumferential portion because of the boss 40 bearing on the slope of the bottom of the this second part goes back up. The boss

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. 40 is a support on the slope of the groove 50 having a reduced surface, which reduces the friction during the rotation of the telescope 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 portion 38 of each tongue 34 enters the circular groove 14 of the housing 4 of the middle part 2 by a radial outward movement, coming at the end of the rotation to lock at the bottom of this groove. The sufficient rotation of the telescope 30 is ensured by the marking "CLOSE" 64 coming in front of the radial line 60, guaranteeing the locking of the tongues 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. During this movement of rotation of the telescope 30 the capsule 20 is held fixed relative to the middle part 2, in particular thanks to the tube 24 of the ring 26 integral with the capsule 20, which is fitted in the slot 12 of this middle part.

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. This facilitates the pivoting of the telescope 30 relative to the capsule 20, and thus the displacement of the tongues 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. 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. The telescope 30 and the capsule 20 are effectively locked in the middle part 2, with little risk of disassembly, wear or failure over time. In a general manner the blocking of the capsule 20 in rotation about its axis relative to the middle part 2, is ensured by the tube 24 of the adjustment wheel integral with the capsule 20, firmly engaged in the slot 12 of this build. The locking in translation of the capsule 20 along the axis, is ensured by the engagement of the tongues 34 in the circular groove 14 of the middle part 2. The bezel 30 is in turn held in abutment on the back of the capsule 20 , thus blocking it in the housing 4 of the middle part 2.

Les figures 8 à 14 illustrent un boîtier 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 4 correspondante.  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 securing means in rotation is formed either by the boss 40 coming to be housed in the assembled position after its locking rotation in a corresponding recess 41, but by a notch 40 'disposed on the circumferential portion 38 of each tongue 34 and wherein is housed, in the assembled position after its locking rotation, a corresponding projection 4.

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 boîtier, 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 device for securing in rotation makes it possible to lock the assembled position of the telescope 30 with respect to the capsule 20 so that, to perform the reverse movement, namely the pivoting of the telescope 30 with respect to the capsule 20 in the direction an unlocking to open the housing, it is necessary to pass a notch ensuring the safety of the assembly and avoiding any unexpected rotation of the telescope 30. Note that in the case of the notch 40 ', the notch is disposed along an axis substantially parallel to the axis of the capsule 20 while in the case of the boss 40, this stop is substantially radial to said axis because the notch is oriented substantially axially by compared 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.  The invention is described in the foregoing by way of example. It is understood that the skilled person is able to achieve different embodiments of the invention without departing from the scope of the invention.
