The strips have an interaction element for interaction between the strips. The element acts on one of the strips when a third strip is actuated in the closing and/or opening phase of the clasp. The third strip includes a finger (15), which contacts on the strips when the third strip is actuated to cause locking/unlocking and/or setting of motion of the strips. An independent claim is also included for a bracelet.

Description

IntroductionIntroduction

La présente invention concerne un fermoir pour montre-bracelet, ainsi qu'un bracelet et une montre-bracelet en tant que tels comprenant un tel fermoir.The present invention relates to a clasp for a wristwatch, and a bracelet and a wristwatch as such comprising such a clasp.

Etat de l'ArtState of the art

II existe plusieurs solutions pour accrocher les deux brins d'un bracelet de montre autour du poignet de son porteur. La première solution est simple et consiste à doter les extrémités de chaque brin de moyens de coopération, sous la forme par exemple d'une simple boucle et d'un ardillon d'une part coopérant avec des trous d'autre part. Une telle solution présente l'inconvénient que lors de l'ouverture des moyens de coopération, les deux brins du bracelet sont immédiatement désolidarisés et entraînent un risque de chute de la montre-bracelet.There are several solutions for hanging the two strands of a watch strap around the wrist of its wearer. The first solution is simple and consists in providing the ends of each strand with cooperation means, in the form for example of a simple loop and a barb on the one hand cooperating with holes on the other hand. Such a solution has the disadvantage that when opening the cooperation means, the two strands of the bracelet are immediately disengaged and lead to a risk of falling of the wristwatch.

Pour pallier à cet inconvénient, une autre solution consiste à prévoir un élément intermédiaire de type fermoir, disposé entre les deux brins de bracelet, qui reste toujours solidaire des extrémités de ces deux brins. Un tel fermoir occupe deux positions : une position fermée, prévue pour le port de la montre, dans laquelle le bracelet et le fermoir s'étendent sur le pourtour du poignet en présentant une longueur totale permettant le maintien de la montre-bracelet, et une position ouverte qui permet d'augmenter la longueur du bracelet et du fermoir, en écartant les deux extrémités des deux brins du bracelet, sans les détacher du fermoir, pour permettre le passage de la main et le retrait de la montre. Dans cette configuration ouverte du fermoir, les deux brins du bracelet ne sont pas désolidarisés, ce qui minimise le risque de chute de la montre.To overcome this drawback, another solution is to provide an intermediate clasp type element disposed between the two bracelet strands, which remains always integral with the ends of these two strands. Such a clasp occupies two positions: a closed position, intended for the wearing of the watch, in which the bracelet and the clasp extend around the circumference of the wrist with a total length allowing the wristwatch to be held, and a open position that increases the length of the bracelet and the clasp, by separating the two ends of the two strands of the bracelet, without detaching the clasp, to allow the passage of the hand and the removal of the watch. In this open configuration of the clasp, the two strands of the bracelet are not disconnected, which minimizes the risk of falling of the watch.

Un fermoir de l'état de la technique, appelé « fermoir double déployant », comprend deux lames montées mobiles en rotation respectivement aux deux extrémités d'une lame centrale, et repliables sur cette lame centrale. Ces trois lames dépliantes permettent d'augmenter sensiblement la longueur du bracelet en position d'ouverture du fermoir.A clasp of the state of the art, called "double folding clasp", comprises two mounted blades rotatably respectively at the two ends of a central blade, and foldable on the central blade. These three folding blades can significantly increase the length of the bracelet in the open position of the clasp.

Le document CH649205 illustre un exemple de réalisation d'un fermoir double déployant. Cette solution présente un premier inconvénient de dépendre des matériaux utilisés car elle dépend en partie de l'élasticité des lames du fermoir. Un tel fermoir présente alors des caractéristiques variables en fonction des matériaux utilisés, par exemple l'or ou l'acier, ce qui n'est pas idéal. Un second inconvénient de cette solution provient du fait qu'elle nécessite deux opérations distinctes pour sa fermeture et son ouverture, car les deux lames mobiles sont manoeuvrées de manière indépendantes l'une de l'autre. Enfin, l'accrochage de ces deux lames mobiles n'est pas très performant, peu sécurisé et entraîne une usure rapide des éléments de crantage utilisés.The document CH649205 illustrates an embodiment of a double clasp deploying. This solution has a first disadvantage of depending on the materials used because it depends in part on the elasticity of the clasp blades. Such a clasp then has variable characteristics depending on the materials used, for example gold or steel, which is not ideal. A second disadvantage of this solution comes from the fact that it requires two separate operations for its closure and its opening, because the two movable blades are operated independently of one another. Finally, the attachment of these two mobile blades is not very powerful, not very secure and causes rapid wear of the notches used.

Le document CH699044 décrit une autre solution dans laquelle le mécanisme d'accrochage est plus performant. Toutefois, cette solution reste peu conviviale car elle nécessite toujours un nombre de manipulations trop important pour son actionnement.The document CH699044 describes another solution in which the attachment mechanism is more efficient. However, this solution is not very user-friendly because it always requires a number of manipulations too important for its actuation.

Le document EP1925227 propose l'ajout d'un bouton d'actionnement, relié à un mécanisme de verrouillage/déverrouillage des lames. Même si cette solution permet l'ouverture du fermoir par la seule opération d'actionnement du bouton, elle n'est pas acceptable car ce bouton et le mécanisme associé ont un impact trop important et négatif sur l'aspect esthétique du fermoir.The document EP1925227 proposes the addition of an actuation button, connected to a mechanism of locking / unlocking the blades. Even if this solution allows the opening of the clasp by the single actuation operation of the button, it is not acceptable because this button and the associated mechanism have a too important and negative impact on the aesthetic appearance of the clasp.

Le document CH689931 décrit une autre solution de fermoir double déployant dans laquelle une première lame permet le maintien d'une seconde en position fermée. L'actionnement des deux lames mobiles doit donc se réaliser dans un ordre bien défini en position de fermeture, ce qui n'est pas acceptable.The document CH689931 describes another solution of double clasp deploying wherein a first blade allows the maintenance of a second in the closed position. The actuation of the two movable blades must therefore be carried out in a well-defined order in the closed position, which is not acceptable.

Il existe donc un besoin d'une solution permettant de porter une montre-bracelet, qui permette de conserver les avantages de l'état de la technique tout en réduisant ses inconvénients.There is therefore a need for a solution for wearing a wristwatch, which allows to retain the advantages of the state of the art while reducing its disadvantages.

C'est pourquoi l'invention cherche à atteindre tout ou partie des objets suivants.This is why the invention seeks to achieve all or part of the following objects.

Un premier objet de l'invention consiste à proposer une solution de fermeture d'un bracelet à l'aide d'un fermoir dont la manipulation est très conviviale.A first object of the invention is to provide a closing solution of a bracelet with a clasp whose handling is very user-friendly.

Un second objet de l'invention consiste à proposer une solution de fermeture d'un bracelet pour montre à l'aide d'un fermoir dont l'accrochage en position fermée est sécurisé.A second object of the invention is to provide a closing solution of a wristwatch for a watch with a clasp whose attachment in the closed position is secured.

Un troisième objet de l'invention consiste à proposer une solution de fermeture d'un bracelet pour montre à l'aide d'un fermoir dont la manipulation n'entraîne pas une usure trop rapide et reste indépendante des matériaux utilisés.A third object of the invention is to provide a closing solution of a wristwatch with a clasp whose handling does not lead to wear too fast and remains independent of the materials used.

Brève description de l'inventionBrief description of the invention

A cet effet, l'invention repose sur un fermoir pour bracelet, caractérisé en ce que deux lames mobiles comprennent au moins un élément de coopération entre elles qui agit sur au moins l'une d'entre elles lorsque l'une d'entre elles est actionnée, en phase de fermeture et/ou d'ouverture du fermoir. ....For this purpose, the invention is based on a clasp for a bracelet, characterized in that two movable blades comprise at least one element of cooperation between them which acts on at least one of them when one of them is actuated, during closing and / or opening of the clasp. ....

L'invention est précisément définie par les revendications.The invention is precisely defined by the claims.

Un mode de réalisation particulier d'un fermoir double déployant va maintenant être décrit de manière détaillée à titre non limitatif.A particular embodiment of a double folding clasp will now be described in detail without limitation.

Comme représenté sur la figure 1, le fermoir double déployant comprend une lame centrale 3 aux extrémités de laquelle sont respectivement montées mobile en pivotement une première lame mobile 10 repliable et une seconde lame mobile 20 repliable, autour de respectivement un premier axe 1 et un second axe 2. Des gorges 9 sont réalisées sur la lame centrale 3 pour faciliter le logement des lames mobiles 10, 20 en position repliée et minimiser l'épaisseur globale du fermoir. Chacune des deux lames mobiles 10, 20 comprend à son extrémité libre 11, 21, opposée à son axe de liaison 1, 2 avec la lame centrale 3, un moyen de liaison avec un brin de bracelet. Notamment, elle comprend au moins une première maille 14, 24 montée mobile en rotation sur cette extrémité libre. Elle comprend aussi un dispositif de verrouillage et/ou de déverrouillage prévu pour mettre en oeuvre son verrouillage et déverrouillage sur la lame centrale pour obtenir les configurations fermée, représentée en vue de dessus sur la figure 2, et/ou ouverte, représentée sur la figure 1, du fermoir, comme cela va être illustré par la suite.As shown on the figure 1 , the double folding clasp comprises a central blade 3 at the ends of which are respectively movably pivoted a first foldable movable blade 10 and a second foldable movable blade 20, about respectively a first axis 1 and a second axis 2. Gorges 9 are made on the central blade 3 to facilitate the housing of the movable blades 10, 20 in the folded position and minimize the overall thickness of the clasp. Each of the two movable blades 10, 20 comprises at its free end 11, 21, opposite its connecting axis 1, 2 with the central blade 3, a connecting means with a bracelet strand. In particular, it comprises at least one first mesh 14, 24 rotatably mounted on this free end. It also comprises a locking and / or unlocking device provided to implement its locking and unlocking on the central blade to obtain the closed configurations, represented in plan view on the figure 2 , and / or open, represented on the figure 1 clasp, as will be illustrated later.

L'invention ne porte pas spécifiquement sur le dispositif de verrouillage et/ou de déverrouillage des lames mobiles 10, 20. Elle est avantageusement compatible avec un dispositif de verrouillage convivial et sûr qui est particulièrement performant. Ainsi, elle utilise, par exemple, la solution visible sur la figure 3 qui est décrite dans le document EP1654950 . Pour cela, chacune des deux lames mobiles 10, 20 comprend vers son extrémité libre un levier 12, 22 solidaire d'un élément d'accrochage 13, 23 en forme de crochet, apte à coopérer avec un plot d'accrochage 4, 5 agencé dans une zone prédéfinie à la surface de la lame centrale 3, par exemple une zone centrale à la surface de la lame centrale 3, solidaire de cette dernière. Ce levier 12, 22 est plus précisément monté en rotation autour d'un axe 31, 32 sur la maille 14, 24 liée à l'extrémité libre 11, 22 de la lame mobile 10, 20.The invention does not specifically relate to the locking device and / or unlocking movable blades 10, 20. It is advantageously compatible with a user friendly and secure locking device that is particularly effective. So, she uses, for example, the visible solution on the figure 3 which is described in the document EP1654950 . For this, each of the two movable blades 10, 20 comprises towards its free end a lever 12, 22 secured to a hooking element 13, 23 in the form of a hook, adapted to cooperate with a latching stud 4, 5 arranged in a predefined area on the surface of the central blade 3, for example a central zone on the surface of the central blade 3, integral with the latter. This lever 12, 22 is more precisely mounted in rotation about an axis 31, 32 on the mesh 14, 24 connected to the free end 11, 22 of the movable blade 10, 20.

Selon ce mode de réalisation, la première lame mobile 10 est solidaire d'un doigt 15 pour coopérer avec la seconde lame mobile 20, visible sur la figure 4 qui représente une coupe au niveau de ce doigt du fermoir en configuration fermée. Comme cela apparaît, le doigt 15 dépasse de l'extrémité du levier 12 et vient se loger sous le levier 22 de la seconde lame mobile 20. Cette solution permet à un porteur du fermoir de déverrouiller et libérer simultanément les deux lames mobiles 10, 20 en actionnant le seul levier 12 de la première lame. En effet, comme cela ressort de la figure 5 qui illustre le début d'une phase d'ouverture du fermoir, le déverrouillage du levier 12 et le déploiement de la première lame mobile 10 entraîne dans son mouvement le déploiement de la seconde lame mobile 20, sous l'effet de son contact avec le doigt 15 qui vient en contact avec la surface du levier 22 associé à cette seconde lame mobile 20.According to this embodiment, the first movable blade 10 is secured to a finger 15 to cooperate with the second movable blade 20, visible on the figure 4 which represents a section at this finger of the clasp in closed configuration. As it appears, the finger 15 protrudes from the end of the lever 12 and is housed under the lever 22 of the second movable blade 20. This solution allows a holder of the clasp to simultaneously unlock and release the two movable blades 10, 20 by operating the single lever 12 of the first blade. Indeed, as is apparent from the figure 5 which illustrates the beginning of an opening phase of the clasp, the unlocking of the lever 12 and the deployment of the first movable blade 10 causes in its movement the deployment of the second movable blade 20, under the effect of its contact with the finger 15 which comes into contact with the surface of the lever 22 associated with this second movable blade 20.

Comme cela est particulièrement visible sur la figure 6, le doigt 15 est disposé dans un évidement 16 de la maille 14. II coopère avec un élément élastique 17, comme un ressort hélicoïdal au sein de ce mode de réalisation, qui le maintient dans une position qui déborde de la maille, comme cela a été vu ci-dessus par exemple en référence à la figure 4. Une bague 18, disposée vers l'extrémité extérieure de l'évidement 16, forme une butée pour le doigt 15. L'élément élastique 17 agit préférentiellement en compression, et agit de préférence toujours en tension, de sorte à exercer en permanence une force sur le doigt 15 qui tend à le plaquer à l'encontre de cette bague 18. En variante, l'élément élastique peut être au repos ou proche de sa position de repos lorsque le doigt 15 est en contact avec la bague 18. L'évidement 16 est dimensionné pour permettre au doigt 15 de s'escamoter en se déplaçant en son sein, à l'encontre de l'élément élastique 17.As is particularly visible on the figure 6 the finger 15 is disposed in a recess 16 of the mesh 14. It cooperates with an elastic element 17, such as a coil spring within this embodiment, which holds it in a position which protrudes beyond the mesh, as has been been seen above for example with reference to the figure 4 . A ring 18, disposed towards the outer end of the recess 16, forms a stop for the finger 15. The elastic element 17 preferably acts in compression, and preferably always acts in tension, so as to permanently exert a force on the finger 15 which tends to press against this ring 18. Alternatively, the elastic member may be at rest or close to its rest position when the finger 15 is in contact with the ring 18. The recess 16 is dimensioned to allow the finger 15 to retract by moving within it, against the elastic element 17.

Cette solution a pour effet complémentaire de permettre la fermeture des deux lames mobiles 10, 20 dans un ordre quelconque. En effet, la première lame mobile 10 qui comprend le doigt 15 peut naturellement être fermée la première. En revanche, si la seconde lame mobile 20 est fermée la première, comme cela est illustré sur la figure 7, alors le doigt 15 débordant du levier 12 qui est lié à la première lame mobile 10 vient en contact avec l'extrémité de la seconde lame mobile 20 lors de sa fermeture, plus précisément de l'extrémité de son levier 22 dans ce mode de réalisation. Lors de ce contact, le doigt 15 s'escamote totalement entièrement ou en partie à l'intérieur de l'évidement 16, comme illustré par la figure 8, jusqu'à ce que la première lame mobile 10 atteigne sa position fermée, illustrée par la figure 9, dans laquelle le doigt retrouve sa position non escamotée dans un espace prévu sous le levier 22 de la seconde lame mobile 20.This solution has the complementary effect of allowing the closing of the two movable blades 10, 20 in any order. Indeed, the first movable blade 10 which comprises the finger 15 can naturally be closed first. On the other hand, if the second movable blade 20 is closed first, as illustrated in FIG. figure 7 , then the finger 15 protruding from the lever 12 which is connected to the first movable blade 10 comes into contact with the end of the second movable blade 20 when it is closed, more precisely from the end of its lever 22 in this mode of production. During this contact, the finger 15 retracts totally or partially inside the recess 16, as illustrated by the figure 8 , until the first movable blade 10 reaches its closed position, illustrated by the figure 9 , in which the finger finds its non-retracted position in a space provided under the lever 22 of the second movable blade 20.

En remarque, les extrémités du doigt 15, des leviers 12, 22 et éventuel organe de préhension des leviers présentent une forme telle que leur interaction dans toutes les phases d'ouverture et fermeture de lames mobiles ne provoque aucun blocage de leurs mouvements respectifs, mais exerce le cas échéant une force orientée de telle manière qu'elle induit l'escamotage du doigt.Note that the ends of the finger 15, levers 12, 22 and any levers lever member have a shape such that their interaction in all phases of opening and closing blades movable does not cause any blocking of their respective movements, but if necessary exerts a force oriented so that it induces the retraction of the finger.

La première lame mobile 10, plus précisément son levier 12, comprend un organe de préhension 19 pour faciliter sa manipulation, notamment son ouverture, puisqu'elle est destinée à être ouverte la première, avant d'entraîner automatiquement l'ouverture de la seconde lame mobile 20. Avantageusement, cet organe de préhension 19 est disposé dans la partie supérieure du levier 12, partiellement noyé dans la surface supérieure du levier 12 pour minimiser l'épaisseur totale du fermoir et s'inscrire dans la continuité du bracelet, comme cela apparaît sur les figures 2 et 10. Une découpe 29 est aménagée sur la face supérieure du levier 22 de la seconde lame mobile 20, en vis-à-vis de l'organe de préhension 19, pour faciliter sa préhension. Ainsi, l'actionnement de cet organe de préhension entraîne le déverrouillage de la première lame mobile 10, puis son ouverture, qui induit l'actionnement du levier 22 de la seconde lame mobile 20 et son déverrouillage.The first movable blade 10, more precisely its lever 12, comprises a gripping member 19 to facilitate its handling, especially its opening, since it is intended to be opened first, before automatically driving the opening of the second blade 20. Advantageously, this gripping member 19 is disposed in the upper part of the lever 12, partially embedded in the upper surface of the lever 12 to minimize the total thickness of the clasp and fit into the continuity of the bracelet, as appears on the figures 2 and 10 . A cutout 29 is arranged on the upper face of the lever 22 of the second movable blade 20, vis-à-vis the gripping member 19, to facilitate its gripping. Thus, the actuation of this gripping member causes the unlocking of the first movable blade 10, and then its opening, which induces the actuation of the lever 22 of the second movable blade 20 and its unlocking.

Dans cette solution, chaque lame mobile 10, 20 est donc dotée de son propre dispositif de verrouillage/déverrouillage qui lui permet d'être maintenue en position repliée sur la lame centrale 3. Comme cela a été vu et illustré précédemment, ce dispositif de verrouillage/déverrouillage peut être du type de celui décrit dans le document EP1654950 . Pour cela, chaque lame mobile 10, 20 comprend donc vers son extrémité libre un levier 12, 22 solidaire d'un organe d'accrochage, comme cela a été vu. Ce levier est associé à un organe élastique 27, 37 qui exerce un couple sur lui, tendant à sa rotation dans le sens permettant le verrouillage de son organe d'accrochage. Cet élément élastique 27 de la première lame mobile 10 est visible sur la figure 11 d'une coupe selon un second plan décalé III-III du fermoir en configuration légèrement ouverte. L'élément élastique 27 peut consister en un ressort agencé autour d'un axe 28, dont une extrémité prend appui sur une partie solidaire de la lame mobile 10, la maille 14 notamment, distincte du levier 12, et dont une seconde extrémité prend appui sur le levier 12. Ce dernier comprend de plus une butée 12a qui limite ce mouvement de rotation à une inclinaison correspondant à la position verrouillée.In this solution, each movable blade 10, 20 is thus provided with its own locking / unlocking device which allows it to be held in the folded position on the central blade 3. As has been seen and illustrated above, this locking device / Unlocking can be of the type described in the document EP1654950 . For this, each movable blade 10, 20 thus comprises towards its free end a lever 12, 22 integral with a fastening member, as has been seen. This lever is associated with an elastic member 27, 37 which exerts a torque on it, tending to its rotation in the direction allowing the locking of its fastening member. This elastic element 27 of the first movable blade 10 is visible on the figure 11 a section according to a second shifted plane III-III of the clasp in slightly open configuration. The elastic element 27 can consist of a spring arranged around an axis 28, one end of which bears on a part integral with the movable blade 10, the mesh 14 in particular, distinct from the lever 12, and whose second end bears on the lever 12. the latter further comprises a stop 12a which limits this rotational movement to an inclination corresponding to the locked position.

L'élément élastique 37 de la deuxième lame mobile 20 est visible sur les coupes des figures 4, 5, 7, et 8 réalisées selon un plan décalé II-II du fermoir. L'élément élastique 37 peut consister en un ressort agencé autour d'un axe 38, dont une extrémité prend appui sur une partie solidaire de la lame mobile 20, la maille 24 notamment, distincte du levier 22, et dont une seconde extrémité prend appui sur le levier 22. Ce dernier comprend de plus une butée 22a qui limite ce mouvement de rotation à une inclinaison correspondant à la position verrouillée.The elastic element 37 of the second movable blade 20 is visible on the sections of the Figures 4, 5 , 7, and 8 carried out according to an offset plane II-II of the clasp. The elastic element 37 may consist of a spring arranged around an axis 38, one end of which bears on a part integral with the movable blade 20, the mesh 24 in particular, distinct from the lever 22, and of which a second end bears on the lever 22. The latter further comprises a stop 22a which limits this rotational movement to an inclination corresponding to the locked position.

Finalement, comme cela a été explicité, le fermoir selon le mode de réalisation de l'invention présente les avantages suivants :

  • II permet le déverrouillage et/ou le déploiement, au moins partiel, des deux lames mobiles en n'actionnant qu'une seule des deux lames mobiles, ou son dispositif de verrouillage/déverrouillage, ce qui entraîne automatiquement le déverrouillage et/ou l'ouverture de la seconde lame mobile ;
  • Les deux lames mobiles peuvent être fermées dans un ordre quelconque. Si la lame (10) est fermée avant la lame (20), le doigt (15) n'intervient pas dans la phase de fermeture de ces deux lames. Si la lame (10) est fermée après la lame (20), le doigt (15) est escamoté ;
  • Le verrouillage des deux lames mobiles peut être fiable et sécurisé, puisque la solution est compatible avec l'implémentation de dispositifs de verrouillage/déverrouillage très performants, indépendants des matériaux utilisés.
Finally, as has been explained, the clasp according to the embodiment of the invention has the following advantages:
  • It allows the unlocking and / or the deployment, at least partially, of the two mobile blades by actuating only one of the two movable blades, or its locking / unlocking device, which automatically causes the unlocking and / or the opening the second movable blade;
  • The two movable blades can be closed in any order. If the blade (10) is closed before the blade (20), the finger (15) does not intervene in the closing phase of these two blades. If the blade (10) is closed after the blade (20), the finger (15) is retracted;
  • The locking of both mobile blades can be reliable and secure, since the solution is compatible with the implementation high-performance locking / unlocking devices, independent of the materials used.

Naturellement, un grand nombre des composants de ce fermoir double déployant pourraient se présenter différemment.Naturally, many of the components of this double folding clasp could be different.

Par exemple, le doigt 15 de coopération pourrait prendre toute autre forme, pourrait être tout élément de coopération. Il pourrait y avoir deux ou plus de deux doigts, pour stabiliser la coopération. Cet élément de coopération pourrait n'avoir qu'une action limitée sur la seconde lame mobile, comme son seul déverrouillage ou entraînement, sur une course plus ou moins longue. Il pourrait, dans une variante simplifiée, ne pas être escamotable. Selon une autre variante, il pourrait être escamoté par un autre mouvement qu'une course linéaire, comme par une rotation. Naturellement, il peut être disposé sur l'une ou l'autre des deux lames mobiles, voire être réparti partiellement sur les deux lames mobiles. En variante encore, les deux lames mobiles peuvent être équipées d'un élément de coopération, pour permettre par exemple l'ouverture du fermoir par l'actionnement de l'une ou l'autre des deux lames mobiles.For example, the cooperation finger could take any other form, could be any element of cooperation. There could be two or more fingers, to stabilize the cooperation. This element of cooperation may have only limited action on the second movable blade, as its only unlocking or training, on a longer or shorter stroke. It could, in a simplified variant, not be retractable. According to another variant, it could be retracted by a movement other than a linear stroke, as by a rotation. Naturally, it can be arranged on one or the other of the two movable blades, or even be partially distributed on the two movable blades. In another variant, the two movable blades may be equipped with a cooperation element, to allow for example the opening of the clasp by the actuation of one or the other of the two movable blades.

De plus, les lames mobiles pourraient prendre d'autres formes, être ou ne pas être symétriques, comprendre tout type de dispositif de verrouillage et/ou déverrouillage. D'une manière générale, l'architecture du fermoir lui-même peut être différente.In addition, the movable blades could take other forms, be or not be symmetrical, include any type of locking device and / or unlocking. In general, the architecture of the clasp itself may be different.

L'invention a été illustrée à partir d'un bracelet associé à une montre-bracelet, qui est d'ailleurs aussi concernée en tant que telle par cette invention. En variante, le fermoir peut être associé à tout autre bracelet, pour tout objet à fixer sur un poignet ou toute autre partie. Cet objet peut être un accessoire de plongée sous-marine tel un profondimètre ou un ordinateur de plongée sous-marine par exemple, ou encore un composant de joaillerie.The invention has been illustrated from a bracelet associated with a wristwatch, which is also concerned as such by this invention. Alternatively, the clasp can be associated with any other bracelet, for any object to be fixed on a wrist or any other part. This object can be a scuba diving accessory such as a depth gauge or a scuba diving computer, for example, or a jewelery component.
