Description

Boîte de montre incluant un fermoir de bracelet Watch case including a bracelet clasp

La présente invention concerne une boîte de montre incluant un fermoir de bracelet, en particulier un fermoir déployant pour bracelet souple. Les montres-bracelets comportent généralement une boîte de montre contenant notamment le mouvement, un bracelet et un fermoir de bracelet permettant d'ouvrir et de fermer le bracelet pour enfiler ou retirer la montre. Le fermoir est le plus souvent disposé à 180° de la boîte le long du bracelet. Il existe de nombreux types de fermoirs pour bracelets souples ou rigides ; on admet cependant que les fermoirs à boucle déployante, qui permettent de varier la longueur du bracelet sans dissocier les deux brins, apportent une sécurité plus importante.The present invention relates to a watch case including a bracelet clasp, in particular a folding clasp for flexible bracelet. Wristwatches generally include a watch case containing in particular the movement, a bracelet and a bracelet clasp allowing to open and close the bracelet to put on or take off the watch. The clasp is most often placed 180 ° from the box along the bracelet. There are many types of clasps for flexible or rigid bracelets; however, it is accepted that the clasps with folding clasp, which allow the length of the bracelet to be varied without dissociating the two strands, provide greater security.

Les fermoirs à boucle déployante comportent généralement plusieurs lames métalliques superposées en position repliée. Si la courbure des lames ne correspond pas au diamètre du poignet, ces fermoirs peuvent être inconfortables. D'autre part, le contact avec du métal aussi bien sur la face supérieure du poignet que sur la face inférieure augmente le risque d'allergies au nickel, par exemple.Folding clasps generally have several metal blades superimposed in the folded position. If the curvature of the blades does not match the diameter of the wrist, these clasps can be uncomfortable. On the other hand, contact with metal on both the upper side of the wrist and the lower side increases the risk of allergies to nickel, for example.

On connaît aussi des montres dans lesquelles le fermoir est intégré à la boîte. La boîte comporte dans ce cas plusieurs lames déployantes qui se superposent sur ou sous le boîtier en position repliée. US4748604, US2429950 et le modèle d'utilité DE-U-752757 décrivent des exemples d'un tel fermoir.Watches are also known in which the clasp is integrated into the case. In this case, the box has several folding blades which are superimposed on or under the case in the folded position. US4748604, US2429950 and the utility model DE-U-752757 describe examples of such a clasp.

CH156174 décrit une autre montre-bracelet combinée avec un fermoir à trois lames. La carrure est montée sur la lame intermédiaire du fermoir tandis que la lame supérieure est conformée en cadre se repliant par-dessus cette carrure. Cette construction est complexe et élargit la montre. Les trois parties du fermoir sont clairement visibles lorsque le fermoir est replié. Lorsque le fermoir est entièrement déplié, le cadran est retourné contre le bas, ce qui risque de rayer la glace contre la surface de la table. Par ailleurs, le cadran est lu à travers une première glace fermant la carrure et une deuxième carrure liée au cadre ; ces deux glaces superposées rendent la lecture peu lisible, augmentent l'épaisseur de la montre et son coût. La longueur du bracelet peut être ajustée et adopter plusieurs positions discrètes définies par des trous pour engager la barrette du bracelet ; un réglage plus fin, en continu, n'est pas possible. a carrure est fermée par une première glace tandis que la cadre supérieureCH156174 describes another wristwatch combined with a three-blade clasp. The middle is mounted on the intermediate blade of the clasp while the upper blade is shaped as a frame that folds over this middle. This construction is complex and expands the watch. The three parts of the clasp are clearly visible when the clasp is folded. When the clasp is fully unfolded, the dial is turned upside down, which could scratch the glass against the surface of the table. Furthermore, the dial is read through a first crystal closing the middle part and a second middle part linked to the frame; these two superimposed glasses make the reading difficult to read, increase the thickness of the watch and its cost. The length of the bracelet can be adjusted and adopt several discrete positions defined by holes to engage the bar of the bracelet; finer, continuous adjustment is not possible. the middle is closed by a first crystal while the upper frame

La présente invention concerne une amélioration aux boîtes de montre incluant un fermoir déployant.The present invention relates to an improvement to watch cases including a folding clasp.

La présente invention vise en particulier à améliorer les possibilités de réglage personnalisé de la longueur du bracelet souple avec un fermoir.The present invention aims in particular to improve the possibilities of personalized adjustment of the length of the flexible bracelet with a clasp.

La présente invention vise également à offrir une construction alternative de boîte de montre incorporant un fermoir.The present invention also aims to offer an alternative construction of a watch case incorporating a clasp.

La présente invention propose donc une boîte de montre comprenant un fermoir déployant pour bracelet souple avantageuse grâce aux caractéristiques suivantes : une carrure liée à un premier brin du bracelet, un socle comprenant une première extrémité liée de manière articulée au second brin du bracelet, une rallonge reliée de manière articulée à la carrure et au socle, les articulations étant agencées de manière à permettre la superposition de la carrure, de la rallonge et du socle en position repliée, et la juxtaposition de la carrure, de la rallonge et du socle en position déployée, une came ou un élément de réglage pour maintenir par compression et/ou friction le bracelet contre le socle, cet élément pouvant être basculé, déplacé ou pivoté pour augmenter ou réduire de manière réversible la longueur en position repliée du bracelet. L'invention part notamment de la constatation nouvelle que les boîtes de montre combinées avec un fermoir de type connu ne permettent pas de régler la longueur du bracelet de manière entièrement satisfaisante. Les moyens de réglage de longueur de bracelet sont souvent peu pratiques, ou nécessitent un bracelet formé avec un profil particulier, coûteux à injecter et impossible à réaliser avec certains matériaux. Souvent, la longueur du bracelet peut uniquement être ajustée en coupant le bracelet, ce qui est irréversible, impossible à effectuer sans outil supplémentaire, et peu approprié à des bracelets textiles ou cuirs par exemple dont l'extrémité tend à s'effilocher s'ils sont coupés. D'autres bracelets peuvent uniquement être ajustés à l'aide d'un outil supplémentaire nécessaire pour retirer une goupille par exemple. Enfin, on connaît aussi des montres avec une boucle déployante près de la carrure et un fermoir séparé, permettant un réglage de longueur, entre les deux extrémités des brins du bracelet opposés à la carrure. Ces montres réduisent considérablement les avantages qui peuvent être attendus des boîtes-fermoirs.The present invention therefore provides a watch case comprising a folding clasp for an advantageous flexible bracelet thanks to the following characteristics: a middle part linked to a first strand of the bracelet, a base comprising a first end linked in an articulated manner to the second strand of the bracelet, an extension hingedly connected to the middle part and the base, the articulations being arranged so as to allow the superposition of the middle part, of the extension and of the base in the folded position, and the juxtaposition of the middle part, of the extension and of the base in position deployed, a cam or an adjustment element to hold the bracelet by compression and / or friction against the base, this element being able to be tilted, moved or pivoted to increase or reduce in a reversible way the length in the folded position of the bracelet. The invention starts in particular from the new observation that watch cases combined with a clasp of known type do not make it possible to adjust the length of the bracelet entirely satisfactorily. The bracelet length adjustment means are often impractical, or require a bracelet formed with a particular profile, costly to inject and impossible to produce with certain materials. Often, the length of the bracelet can only be adjusted by cutting the bracelet, which is irreversible, impossible to perform without an additional tool, and unsuitable for textile or leather bracelets for example, the end of which tends to unravel if are cut. Other straps can only be adjusted using an additional tool needed to remove a pin, for example. Finally, watches are also known with a folding clasp near the middle and a separate clasp, allowing a length adjustment, between the two ends of the strands of the bracelet opposite the middle. These watches greatly reduce the benefits that can be expected from clasp boxes.

Suivant une variante préférée de la présente invention, le bracelet est constitué d'un seul brin présentant deux extrémités, ayant classiquement la forme d'une bande. Il peut être fabriqué dans un matériau habituellement utilisé pour les bracelets de montre, tel que le cuir, un textile ou encore, de préférence, un matériau extensible, en particulier un élastomère. Selon cette variante préférée, l'une des deux extrémités du bracelet est liée à la carrure de la boîte de montre, tandis que la seconde extrémité est liée au socle. Avantageusement, l'élément de réglage précité comprend un élément de verrouillage agissant en bloquant ou appuyant sur une portion sélectionnable du bracelet. Il peut ainsi être mis en œuvre avec n'importe quel type de bracelet, sans exiger un profil particulier du bracelet. Pour autant, ceci n'exclut pas la présence d'un tel profil particulier pour renforcer l'effet de verrouillage, tel qu'un relief en forme de stries, en fonction notamment de la nature du matériau utilisé pour le bracelet, avantageusement dans le cas d'un élastomère. La gamme de réglage de longueur du bracelet est de préférence importante, par exemple de l'ordre de la longueur de la boîte de montre.According to a preferred variant of the present invention, the bracelet consists of a single strand having two ends, conventionally having the shape of a band. It can be made from a material usually used for watch straps, such as leather, textile or, preferably, an extensible material, in particular an elastomer. According to this preferred variant, one of the two ends of the bracelet is linked to the middle part of the watch case, while the second end is linked to the base. Advantageously, the aforementioned adjustment element comprises a locking element acting by blocking or pressing on a selectable portion of the bracelet. It can thus be implemented with any type of bracelet, without requiring a particular profile of the bracelet. However, this does not exclude the presence of such a particular profile to reinforce the locking effect, such as a relief in the form of streaks, depending in particular on the nature of the material used for the bracelet, advantageously in the case of an elastomer. The range for adjusting the length of the strap is preferably large, for example of the order of the length of the watch case.

La construction particulière proposée constitue donc une alternative avantageuse aux constructions de l'art antérieur. La présente invention sera mieux comprise à l'aide des figures annexées qui montrent :The particular construction proposed therefore constitutes an advantageous alternative to the constructions of the prior art. The present invention will be better understood with the aid of the appended figures which show:

La figure 7 correspond à la vue de la figure 6, l'élément de réglage apparaissant en position de fermeture. La montre-bracelet de l'invention comporte une carrure 1 dans laquelle est logé un mouvement de montre. Une couronne 10 est liée à une tige de couronne non représentée et permet de mettre le mouvement de montre à l'heure et/ou de régler d'autres fonctions. Le bracelet 4 de la montre est constitué d'un seul brin dont les deux extrémités 40 et 41 sont fixées à la boîte de montre. L'extrémité 41 est ainsi fixée, par exemple au moyen d'une goupille ressort ou d'autres moyens, à la face supérieure à 6 heures de la carrure 1. L'autre extrémité 40 est fixée à 12 heures sur un socle 3 de fermoir décrit plus bas. Le bracelet est avantageusement moulé ou injecté dans un matériau souple et extensible, par exemple dans un matériau à base de silicone, afin de s'adapter parfaitement au diamètre du poignet du porteur. Un profilage 45 est de préférence prévu sur la face interne du bracelet pour améliorer la respiration de la peau et réduire le glissement. La boîte de montre comporte en outre une rallonge de fermoir 2.Figure 7 corresponds to the view of Figure 6, the adjusting element appearing in the closed position. The wristwatch of the invention comprises a middle part 1 in which is housed a watch movement. A crown 10 is linked to a crown rod, not shown, and allows the watch movement to be set on time and / or to adjust other functions. The strap 4 of the watch is made up of a single strand, the two ends 40 and 41 of which are fixed to the watch case. The end 41 is thus fixed, for example by means of a spring pin or other means, to the upper face at 6 o'clock in the middle 1. The other end 40 is fixed at 12 o'clock on a base 3 of clasp described below. The bracelet is advantageously molded or injected in a flexible and extensible material, for example in a silicone-based material, in order to adapt perfectly to the diameter of the wearer's wrist. A profiling 45 is preferably provided on the internal face of the bracelet to improve the respiration of the skin and reduce slippage. The watch case also has a clasp extension 2.

Une extrémité de la rallonge est liée par une première charnière 20 (figure 4) à la face inférieure de la carrure, à 12 heures, tandis que l'autre extrémité de la rallonge est articulée au moyen d'une seconde charnière 21 avec le socle de fermoir 3 à 6 heures. Suivant une variante avantageuse, l'articulation pivotante 20 est une charnière conçue pour être facilement démontée, afin de pouvoir aisément isoler la carrure des autres parties de la montre bracelet. Ceci est particulièrement utile pour pratiquer différentes opérations, notamment pour l'emboîtage du mouvement, du cadran et des aiguilles, ou pour effectuer différents tests, tels que des tests d'étanchéité, ou encore pour faciliter diverses interventions de réparation, le cas échéant. A cet effet, la charnière 20 comporte une barrette amovible 22, visible sur la figure 4.One end of the extension is linked by a first hinge 20 (FIG. 4) to the underside of the middle part, at 12 o'clock, while the other end of the extension is articulated by means of a second hinge 21 with the base. clasp 3 to 6 hours. According to an advantageous variant, the pivoting articulation 20 is a hinge designed to be easily disassembled, in order to be able to easily isolate the middle of the other parts of the wristwatch. This is particularly useful for practicing different operations, in particular for fitting the movement, the dial and the hands, or for carrying out different tests, such as leak tests, or even to facilitate various repair operations, if necessary. To this end, the hinge 20 includes a removable bar 22, visible in FIG. 4.

Dans l'exemple préférentiel illustré, la rallonge est formée d'un cadre (étrier) métallique creux, ce qui permet notamment de réduire le poids de la boîte de montre et de loger le fond de la carrure 1 si ce fond est proéminent. De préférence, comme cela est bien visible en particulier sur la figure 2, la rallonge 2 présente la forme d'un étrier ouvert, dont la base est articulée avec le socle 3 par l'intermédiaire de la charnière 21. Ainsi, cette forme particulière de rallonge facilite de plus le logement de l'extrémité 40 du bracelet sous la carrure 1. Toutefois, une rallonge de fermoir en forme de lame pleine ou formée elle-même d'un matériau élastique peut aussi 5 être envisagée dans le cadre de l'invention. Par ailleurs, il est aussi possible dans le cadre de l'invention d'utiliser des rallonges de fermoir en plusieurs éléments pour augmenter encore l'élongation du fermoir lors de l'ouverture du fermoir, ou pour améliorer le confort d'ouverture. Des fermoirs intégrés à la boîte de type papillon peuvent ainsi être utilisés. 0 Le socle 3 est destiné à venir en appui contre le poignet lorsque la montre est portée. Le bloc carrure 1 - socle 3 forme de préférence un ensemble d'aspect monolithique lorsque le fermoir est fermé. Dans ce but, le socle 3 et la carrure 1 s'emboîtent l'un contre l'autre sans seuil à la jonction. 5 Le socle 3 comporte un évidement 30 suffisamment large et profond pour y loger la totalité de la rallonge 2 en position repliée. LaIn the preferred example illustrated, the extension is formed by a hollow metal frame (stirrup), which in particular makes it possible to reduce the weight of the watch case and to accommodate the base of the middle part 1 if this base is prominent. Preferably, as is clearly visible in particular in Figure 2, the extension 2 has the shape of an open stirrup, the base of which is articulated with the base 3 via the hinge 21. Thus, this particular form of extension further facilitates the housing of the end 40 of the bracelet under the middle 1. However, a clasp extension in the form of a solid blade or itself formed of an elastic material can also be envisaged in the context of the invention. Furthermore, it is also possible within the framework of the invention to use clasp extensions in several elements to further increase the elongation of the clasp when the clasp is opened, or to improve the opening comfort. Clasps integrated into the butterfly-type box can thus be used. 0 The base 3 is intended to bear against the wrist when the watch is worn. The middle part 1 - base 3 preferably forms a set of monolithic appearance when the clasp is closed. To this end, the base 3 and the middle part fit together without any threshold at the junction. 5 The base 3 has a recess 30 wide and deep enough to accommodate the entire extension 2 in the folded position. The

- "' rallonge 2 est donc dissimulée entre le socle et la carrure lorsque la montre est portée.- "'extension 2 is therefore hidden between the base and the middle when the watch is worn.

Comme on le voit en particulier sur la figure 3, l'évidement 30 0 permet également de loger l'extrémité 40 du bracelet 4. La profondeur d'engagement du brin 40 dans l'évidement 30 peut être ajustée pour régler la longueur utile du bracelet en fonction de la taille du poignet. Dans le mode d'exécution illustré, le bracelet 4 est maintenu dans le socle 3 par une came excentrique 34 à deux positions, qui peut pivoter parallèlement à 5 l'axe 3 heures - 9 heures entre une position dans laquelle le bracelet est coincé entre la came 34 et le socle 3, et une position de réglage non illustrée dans laquelle l'interstice entre la came 34 et le socle 3 est suffisant pour faire coulisser le bracelet 4. Le bracelet est ainsi maintenu par compression d'une portion arbitraire d'une de ses faces supérieure ou 0 inférieure, et/ou par friction contre les éléments 3 et 34. Comme déjà mentionné, le bracelet est de préférence fait d'un matériau élastique, en sorte qu'il reprend sa forme lorsque la pression de la came 34 est relâchée. La came 34 peut de préférence être libérée uniquement lorsque le fermoir 1, 2, 3 est ouvert ; lorsque la montre est fermée, la boîte 1 bloque la rotation de la came, empêchant ainsi un dérèglement accidentel de la longueur du bracelet. La came 34 est de préférence agencée de manière à ne pas être dégagée par pivotement sans une certaine résistance, même quand le fermoir est ouvert, de manière à permettre l'ouverture du fermoir sans risque de dérégler accidentellement la longueur du bracelet. La résistance au pivotement de la came 34 peut par exemple être provoquée par une compression augmentée du bracelet lors de la rotation de la came. Dans une variante non illustrée, la came 34 ne peut être libérée qu'en agissant sur un organe de commande supplémentaire, par exemple un bouton poussoir, ou en soulevant une des portions du bracelet. La cameAs can be seen in particular in FIG. 3, the recess 30 0 also makes it possible to accommodate the end 40 of the bracelet 4. The depth of engagement of the strand 40 in the recess 30 can be adjusted to adjust the useful length of the bracelet depending on the size of the wrist. In the illustrated embodiment, the bracelet 4 is held in the base 3 by an eccentric cam 34 with two positions, which can pivot parallel to the axis 3 o'clock - 9 o'clock between a position in which the bracelet is wedged between the cam 34 and the base 3, and an adjustment position not illustrated in which the gap between the cam 34 and the base 3 is sufficient to make the bracelet 4 slide. The bracelet is thus held by compression of an arbitrary portion d 'one of its upper or lower faces 0, and / or by friction against the elements 3 and 34. As already mentioned, the bracelet is preferably made of an elastic material, so that it resumes its shape when the pressure of the cam 34 is released. The cam 34 can preferably be released only when the clasp 1, 2, 3 is open; when the watch is closed, the box 1 blocks the rotation of the cam, thus preventing an accidental disruption of the length of the bracelet. The cam 34 is preferably arranged so as not to be released by pivoting without a certain resistance, even when the clasp is open, so as to allow the clasp to be opened without risk of accidentally disrupting the length of the bracelet. The resistance to pivoting of the cam 34 can for example be caused by increased compression of the bracelet during rotation of the cam. In a variant not illustrated, the cam 34 can only be released by acting on an additional control member, for example a push button, or by lifting one of the portions of the bracelet. Drug

34 peut aussi être constituée de plusieurs éléments. La portion visible de la came 34 a de préférence la même forme et le même aspect visuel que l'extrémité 400 du bracelet lié à l'autre face de la boîte, et vient ainsi s'engager entre deux cornes 13 de la carrure.34 can also consist of several elements. The visible portion of the cam 34 preferably has the same shape and the same visual appearance as the end 400 of the bracelet linked to the other face of the case, and thus engages between two horns 13 of the middle part.

Suivant une variante préférée, au moins une butée 35 coopère avec la came 34 afin de limiter la rotation de celle-ci autour de son axe. De préférence, l'angle de rotation de la came sera limité à une valeur inférieure à 90°. A titre d'exemple visible sur les figures 6 et 7, au moins une butée 35 est portée par la came 34, faisant saillie à au moins l'une de ses extrémités. Comme on le voit sur la figure 6, lorsque la came 34 est en position d'ouverture, la butée 35, venant en contact avec la portion 37 de la corne 37 du socle, bloque la rotation de la came.Dans cette position, l'extrémité 40 du bracelet peut librement coulisser sous la came. Dans la position de fermeture de la came 34, représentée sur la figure 7, la butéeAccording to a preferred variant, at least one stop 35 cooperates with the cam 34 in order to limit the rotation of the latter around its axis. Preferably, the angle of rotation of the cam will be limited to a value less than 90 °. As an example visible in Figures 6 and 7, at least one stop 35 is carried by the cam 34, projecting at at least one of its ends. As seen in Figure 6, when the cam 34 is in the open position, the stop 35, coming into contact with the portion 37 of the horn 37 of the base, blocks the rotation of the cam. In this position, the the end 40 of the bracelet can slide freely under the cam. In the closed position of the cam 34, shown in FIG. 7, the stop

35 vient en contact avec le rebord extérieur 38 du socle 3, tandis que la came 34 immobilise par compression l'extrémité 40 du bracelet. On notera que l'ouverture maximale de l'angle de rotation de la came peut être ajustée en jouant sur les dimensions de la butée.35 comes into contact with the outer rim 38 of the base 3, while the cam 34 immobilizes by compression the end 40 of the bracelet. It will be noted that the maximum opening of the angle of rotation of the cam can be adjusted by varying the dimensions of the stop.

La longueur de l'évidement 30 est de préférence maximale, c'est- à-dire qu'elle est égale à la longueur du socle 3 moins une épaisseur du bord de l'évidement. La came 34 est disposée de manière à venir en appui le plus loin possible de l'extrémité de l'évidement la plus proche de l'articulation 21. Cette disposition particulière permet d'augmenter la distance entre la came 34 et le fond de l'évidement près de la charnière 21, et donc de maximiser la gamme de réglage de longueur du bracelet. Le bracelet 4 est engagé sous la rallonge 2 dans le socle 3 ; il est donc éloigné du fond de la carrure 1, qui peut être proéminent selon l'épaisseur du mouvement employé. Ainsi, le fond de la montre/mouvement ne gêne pas pour l'engagement du bracelet. Par ailleurs, la came 34 est agencée pour exercer une pression assez importante sur toute la largeur du bracelet. De cette manière, le risque de glissement du bracelet hors de l'évidement lorsque seule une faible longueur de bracelet est engagée dans le fermoir peut être minimisé. En répartissant la force de maintien de la came 34 sur toute la largeur du bracelet, on réduit par ailleurs la pression locale et donc le risque de marquer durablement la surface du bracelet. La surface d'appui du socle 3 sur la face inférieure du bracelet est de préférence inférieure à la surface de contact entre la came 34 et la face supérieure du bracelet. Cette* disposition particulière permet de maintenir fermement le bracelet grâce à la pression importante sur la face inférieure, tout en minimisant le risque de marquer la face supérieure du bracelet.The length of the recess 30 is preferably maximum, that is to say that it is equal to the length of the base 3 minus a thickness of the edge of the recess. The cam 34 is arranged so as to come to bear as far as possible from the end of the recess closest to the articulation 21. This particular arrangement makes it possible to increase the distance between the cam 34 and the bottom of the 'recess near the hinge 21, and therefore to maximize the range of length adjustment of the bracelet. The bracelet 4 is engaged under the extension 2 in the base 3; it is therefore distant from the bottom of the middle part 1, which can be prominent depending on the thickness of the movement employed. Thus, the back of the watch / movement does not interfere with the engagement of the bracelet. Furthermore, the cam 34 is arranged to exert a fairly significant pressure over the entire width of the bracelet. In this way, the risk of the bracelet sliding out of the recess when only a short length of bracelet is engaged in the clasp can be minimized. By distributing the holding force of the cam 34 over the entire width of the bracelet, it also reduces the local pressure and therefore the risk of lastingly marking the surface of the bracelet. The bearing surface of the base 3 on the underside of the bracelet is preferably less than the contact surface between the cam 34 and the upper face of the bracelet. This particular arrangement allows the bracelet to be held firmly in place by the high pressure on the underside, while minimizing the risk of marking the upper face of the bracelet.

Le maintien du bracelet par friction et/ou compression permet d'utiliser la boîte de montre de l'invention avec n'importe quel type de bracelet souple, y compris des bracelets en cuir ou textile dans lesquels il serait difficile de prévoir des rainures ou des nervures de fixation. Des moyens de butée, par exemple des butées coopérant sur la boîte et sur le bracelet, ou un ardillon engagé dans un trou à travers le bracelet, peuvent cependant aussi être employés.Maintaining the strap by friction and / or compression allows the watch case of the invention to be used with any type of flexible strap, including leather or textile straps in which it would be difficult to provide grooves or fixing ribs. Stop means, for example stops cooperating on the case and on the bracelet, or a pin engaged in a hole through the bracelet, can however also be used.

L'extrémité 40 du bracelet 4 est liée au socle de la boîte de montre. La traction de cette extrémité s'exerce donc suivant une droite sensiblement comprise dans le plan principal du socle. Ainsi, le couple de basculement sur la boîte est minimal, et la face inférieure à 12 heures de celle-ci ne risque pas de se soulever même si le bracelet est porté très tendu. L'extrémité 41 du bracelet liée à la boîte est de préférence coudée avec une marche 400, de manière à ce que la force de traction de cette extrémité s'exerce également selon une droite proche du poignet et sensiblement contenue dans le plan principal du socle 3. La face inférieure du bracelet 4 est ainsi la plus proche possible de la peau du poignet sur toute sa longueur, ce qui est plus esthétique, plus confortable et améliore le maintien de la montre même lors de mouvements brusques.The end 40 of the strap 4 is linked to the base of the watch case. The traction of this end is therefore exerted along a straight line substantially included in the main plane of the base. Thus, the tilting torque on the box is minimal, and the face less than 12 hours of there is no risk of it lifting up even if the bracelet is worn very tight. The end 41 of the bracelet linked to the box is preferably bent with a step 400, so that the pulling force of this end is also exerted along a straight line close to the wrist and substantially contained in the main plane of the base. 3. The underside of bracelet 4 is thus as close as possible to the skin of the wrist over its entire length, which is more aesthetic, more comfortable and improves the maintenance of the watch even during sudden movements.

La boîte de montre 1 comporte un dispositif de verrouillage mécanique permettant de verrouiller le fermoir en position repliée. Ledit dispositif de verrouillage mécanique peut, comme dans l'exemple représenté à la figure 4, comprendre deux boutons-poussoirs 11 et 12 capables d'agir sur des éléments déformables élastiquement. Comme on peut le voir sur la figure 4, les boutons-poussoirs 11 et 12 sont placés sur les deux faces latérales de la carrure 1. On voit que le bouton-poussoir 12 permet d'actionner un crochet 120 mobile lié à la carrure 1 et coopérant avec une butée 33 sur le socle (figure 5). Le bouton-poussoir 12 peut être appuyé contre l'action d'un ressort ou d(une lame, non représentés, pour dégager le crochet 120 de la butée et ouvrir ainsi le fermoir. Une disposition similaire mais symétrique se retrouve de l'autre côté de la boîte. Le fermoir peut de préférence uniquement être ouvert en appuyant simultanément sur les deux boutons-poussoirs 11,12 puis en soulevant la carrure 1 par rapport au socle 3. Le crochet mobile 120 comporte avantageusement une face biseautée 121, visible sur la figure 4, permettant de refermer la boîte-fermoir et d'enfoncer le crochet 120 sans devoir appuyer sur le bouton-poussoir 12. Une face biseautée symétrique, non représentée, se retrouve également sur le crochet 11.The watch case 1 includes a mechanical locking device making it possible to lock the clasp in the folded position. Said mechanical locking device can, as in the example shown in FIG. 4, comprise two push buttons 11 and 12 capable of acting on elastically deformable elements. As can be seen in FIG. 4, the push buttons 11 and 12 are placed on the two lateral faces of the middle part 1. It can be seen that the push button 12 makes it possible to actuate a movable hook 120 linked to the middle part 1 and cooperating with a stop 33 on the base (Figure 5). The push button 12 can be pressed against the action of a spring or a blade ( not shown) to release the hook 120 from the stop and thus open the clasp. A similar but symmetrical arrangement is found on the other side of the box The clasp can preferably only be opened by simultaneously pressing the two push buttons 11,12 and then lifting the middle part relative to the base 3. The movable hook 120 advantageously has a bevelled face 121, visible on FIG. 4, enabling the clasp box to be closed and the hook 120 to be pushed in without having to press the push button 12. A symmetrical bevelled face, not shown, is also found on the hook 11.

La disposition des boutons-poussoirs sur la carrure 1 , plutôt que sur le socle 3, permet de les éloigner du poignet et donc de réduire le risque de blessure du porteur. La couronne 10 est accessible même lorsque le fermoir est replié, en sorte qu'il n'est pas nécessaire de l'ouvrir pour régler l'heure. Suivant une variante préférée de l'invention, la couronne 10 est disposée à 9 heures afin qu'en aucune façon elle ne puisse entrer en contact avec le dos de la main de l'utilisateur.The arrangement of the push buttons on the middle part 1, rather than on the base 3, makes it possible to move them away from the wrist and therefore to reduce the risk of injury to the wearer. The crown 10 is accessible even when the clasp is folded, so that it is not necessary to open it to set the time. According to a preferred variant of the invention, the crown 10 is set at 9 o'clock so that it cannot in any way come into contact with the back of the user's hand.

Un verrouillage de la carrure 1 sur la rallonge 2, ou du socle 3 sur la rallonge, est aussi envisageable dans le cadre de l'invention. Le verrouillage du socle sur la carrure illustré a toutefois l'avantage de maintenir l'ensemble de la boîte 1, 2, 3 fermement en position repliée.Locking the middle part 1 on the extension 2, or the base 3 on the extension, is also conceivable in the context of the invention. Locking the base on the middle part illustrated, however, has the advantage of keeping the entire box 1, 2, 3 firmly in the folded position.

Le socle 3 comporte une encoche semi-circulaire 32 placée en regard de la couronne 10 en position repliée. De la même manière, les boutons-poussoirs 11 et 12 reposent de préférence dans des encoches 31 respectivement 36 du socle. Cette disposition particulière permet de disposer la couronne et les boutons-poussoirs 11 et 12 près de la ligne de jonction entre le socle et la carrure, et ainsi de dissimuler partiellement cette ligne, ou en tout cas de la rendre moins visible.The base 3 includes a semi-circular notch 32 placed opposite the crown 10 in the folded position. In the same way, the push buttons 11 and 12 preferably rest in notches 31 respectively 36 of the base. This particular arrangement makes it possible to place the crown and the push buttons 11 and 12 near the junction line between the base and the middle part, and thus partially conceal this line, or in any case make it less visible.

La boîte de montre objet de la présente invention conviendra particulièrement bien aux personnes pratiquant certains sports, tels que le golf en particulier. The watch case which is the subject of the present invention will be particularly suitable for people practicing certain sports, such as golf in particular.
