Abstract

Clasp is made of a central part (1) with two arms (2,3) hinged at each end and the bracelet being hinged in turn at each free end of the arms. Bolts (23) are going out of the arm side face when the clasp is opened and cooperate with a bore (24) in the central part in order to lock the bracelet. A pushbutton (8) in the opposite side of the central part is integral with two rods sliding within the bore receiving the bolts and when actuated, it pushes the bolts out of the recess and free the arms from the central part of the clasp.

Description

La présente invention se rapporte à un fermoir permettant de relier les deux brins d'un bracelet, notamment d'un bracelet de montre ou d'une gourmette, métallique ou en un autre matériau.The present invention relates to a clasp for connecting the two strands of a bracelet, in particular a watch bracelet or a curb chain, metallic or other material.

On connaít des fermoirs de ce type généralement désignés sous l'appellation de fermoirs déployants. Ces fermoirs présentent des inconvénients qui sont l'élasticité de leurs lames dont la variation influe directement sur la force de clipsage et donc sur la sécurité de la fermeture. De plus ces fermoirs déployants à lames sont relativement fragiles, les lames étant susceptibles de se déformer ou de se tordre altérant ainsi le fonctionnement du fermoir.We know clasps of this type generally referred to the name of folding clasps. These clasps have drawbacks which are the elasticity of their blades whose variation directly influences the force and therefore on the security of the closure. In addition, these clasps deployants with blades are relatively fragile, the blades being susceptible to deforming or twisting thus altering the functioning of the clasp.

Le but de la présente invention est de palier aux inconvénients des fermoirs déployants existants, de renforcer la rigidité du fermoir, de faire en sorte que le verrouillage des lames du fermoir soit indépendant de la forme et de l'élasticité des lames tout en permettant une fabrication aisée et une manipulation simple du fermoir.The object of the present invention is to overcome the drawbacks of clasps existing deployants, to reinforce the rigidity of the clasp, to ensure that the locking of the clasp blades is independent of shape and elasticity blades while allowing easy manufacture and simple handling of the clasp.

Ces buts et d'autres qui seront apparents au vu de la description qui suit sont obtenus par le fermoir selon la présente invention qui se distingue par les caractéristiques énumérées à la revendication 1.These goals and others which will be apparent from the following description are obtained by the clasp according to the present invention which is distinguished by the Features listed in claim 1.

Le dessin annexé illustre schématiquement et à titre d'exemple une forme d'exécution du fermoir déployant pour bracelet selon l'invention.The attached drawing illustrates schematically and by way of example a shape of execution of the folding clasp for bracelet according to the invention.

La figure 1 est une vue en perspective de dessus du fermoir partiellement ouvert.Figure 1 is a perspective view from above of the clasp partially open.

La figure 2 est une vue en perspective de dessous du fermoir partiellement ouvert.Figure 2 is a perspective view from below of the clasp partially open.

La figure 3 est une vue en perspective du fermoir seul (sans les brins du bracelet) partiellement fermé. Figure 3 is a perspective view of the clasp alone (without the strands of the bracelet) partially closed.

Les figures 4 et 5 sont des vues partielles en coupe du fermoir fermé en position verrouillée respectivement déverrouillée.Figures 4 and 5 are partial sectional views of the clasp closed at locked position respectively unlocked.

La forme d'exécution du fermoir déployant selon l'invention comporte une partie centrale 1 et deux bras latéraux 2,3. Chacun de ces bras latéraux est pivoté par l'une de ses extrémités sur une des extrémités de la partie centrale 1 à l'aide d'axes 4 soudés ou rivés, c'est-à-dire montés de façon rigide et durable. Généralement cette partie centrale 1 et ces bras sont incurvés pour épouser la forme arrondie du poignet de l'utilisateur. En position fermée, les bras 2,3 repliés parallèlement à la partie centrale, ces trois pièces sont parallèles et situées dans une même surface ou plan, les bras 2,3 étant situés l'un dans le prolongement de l'autre et côte à côte avec la partie centrale 1.The embodiment of the folding clasp according to the invention comprises a central part 1 and two lateral arms 2,3. Each of these side arms is pivoted by one of its ends on one of the ends of the central part 1 using welded or riveted axes 4, that is to say mounted rigidly and durably. Generally this central part 1 and these arms are curved to marry the rounded shape of the user's wrist. In the closed position, the arms 2,3 folded parallel to the central part, these three parts are parallel and located in the same surface or plane, the arms 2,3 being located one in the extension of the other and side by side with the central part 1.

Les extrémités libres des bras 2,3 sont articulées de façon conventionnelle sur les derniers maillons 5 d'un bracelet 6 à l'aide de goupilles ou vis 7. Il faut noter que ces bras 2,3 sont situés dans le plan de symétrie du bracelet tandis que la partie centrale du fermoir est décalée latéralement par rapport à ce plan de symétrie du bracelet, cette partie centrale 1 étant bien entendu cachée, en position fermée du fermoir, sous le bord du bracelet. Ce fermoir occupe donc une position asymétrique par rapport au bracelet.The free ends of the arms 2,3 are articulated in a conventional manner on the last links 5 of a bracelet 6 using pins or screws 7. It is necessary note that these arms 2,3 are located in the plane of symmetry of the bracelet while the central part of the clasp is offset laterally with respect to this plane of symmetry of the bracelet, this central part 1 being of course hidden, in closed position of the clasp, under the edge of the bracelet. This clasp therefore occupies a asymmetrical position in relation to the bracelet.

Dans cette construction la partie centrale 1 du fermoir et ses bras 2,3 sont rigides, solides et résistants ce qui confère une grande robustesse au fermoir.In this construction, the central part 1 of the clasp and its arms 2, 3 are rigid, solid and resistant which gives great strength to the clasp.

La portion centrale ou médiane de la partie centrale 1 du fermoir comporte un dispositif de verrouillage des bras 2,3 en position fermée. Ce dispositif de verrouillage, illustré à plus grande échelle aux figures 4 et 5, comporte un poussoir 8 de forme trapézoïdale logé dans un évidement 9 que comporte la partie centrale 1.The central or middle portion of the central part 1 of the clasp comprises an arm locking device 2,3 in the closed position. This device locking device, illustrated on a larger scale in FIGS. 4 and 5, comprises a pusher 8 of trapezoidal shape housed in a recess 9 which comprises the central part 1.

Le poussoir 8 est maintenu en place à l'aide de vis 14 traversant la partie centrale 1 du fermoir et dont les têtes sont logées dans des évidements 15 pratiqués dans la tranche de la partie centrale 1 située du côté des branches 2 et 3. Ce poussoir peut se déplacer sur une distance X entre sa position de verrouillage illustrée à la figure 4 et sa position de déverrouillage des bras 2,3 illustrée en figure 5.The pusher 8 is held in place with screws 14 passing through the part central 1 of the clasp and whose heads are housed in recesses 15 practiced in the edge of the central part 1 located on the side of the branches 2 and 3. This pusher can move over a distance X between its position locking illustrated in FIG. 4 and its position for unlocking the arms 2,3 illustrated in figure 5.

En position de verrouillage (figure 4) le poussoir 8 est retenu dans le logement 9 par ses surfaces inclinées et, généralement, la tête des vis 14 est située au fond des évidements 15.In the locking position (Figure 4) the pusher 8 is retained in the housing 9 by its inclined surfaces and, generally, the head of the screws 14 is located at the bottom of the recesses 15.

Le dispositif de verrouillage comporte encore des verrous logés dans des perçages borgnes 20 pratiqués dans les extrémités reliées au bracelet des bras 2 et 3 et débouchant sur la tranche de ceux-ci dirigé vers la partie centrale 1 du fermoir. Ces verrous comportent une douille 21 chassée dans les perçages 20 renfermant un ressort 22 agissant sur la tête d'un organe de verrouillage 23 comportant un doigt pouvant émerger hors de la douille 21 et donc du bras 2 ou 3 sous l'action du ressort 22.The locking device also includes locks housed in blind holes 20 made in the ends connected to the bracelet of the arms 2 and 3 and leading to the edge of these directed towards the central part 1 of the clasp. These locks include a socket 21 driven into the holes 20 containing a spring 22 acting on the head of a locking member 23 comprising a finger which can emerge from the socket 21 and therefore from the arm 2 or 3 under the action of spring 22.

En position verrouillée, (figure 4) les doigts des organes de verrouillage 23 s'étendent à l'intérieur des évidements 15 de la partie centrale 1 du fermoir. On obtient ainsi un verrouillage positif, sûr, indépendant de la forme ou des dimensions des bras 2,3 et surtout extrêmement résistant. La force de fermeture est pratiquement infinie et le fermoir ne peut pas s'ouvrir intempestivement.In the locked position, (figure 4) the fingers of the locking members 23 extend inside the recesses 15 of the central part 1 of the clasp. We thus obtains a positive, secure locking, independent of the form or arm dimensions 2,3 and above all extremely resistant. Closing force is practically infinite and the clasp cannot open unexpectedly.

La partie centrale ou médiane de la partie centrale 1 du fermoir comporte encore un dispositif de guidage et de maintien des bras 2,3 en position fermée.The central or middle part of the central part 1 of the clasp comprises another device for guiding and holding the arms 2,3 in the closed position.

Ce dispositif de guidage et de maintien est constitué par une tige 10 solidaire de la partie centrale 1 et s'étendant perpendiculairement à celle-ci hors de sa face opposée au poussoir 8. Cette tige 10 se termine par une formation de maintien 11 comportant deux pans inclinés 12.This guiding and holding device is constituted by a rod 10 integral with the central part 1 and extending perpendicular thereto outside from its face opposite to the pusher 8. This rod 10 ends in a formation of support 11 comprising two inclined faces 12.

Lorsque les bras 2,3 sont en position de fermeture les pans inclinés 12 de la formation de maintien 11 de la tige 10 sont plaqués contre des pans inclinés 16 que comportent les bras 2,3 à leurs extrémités fixées au bracelet, la tige 10 de la partie centrale 1 venant se loger entre les faces terminales 17 de ces extrémités des bras 2,3. When the arms 2,3 are in the closed position the inclined faces 12 of the retaining formation 11 of the rod 10 are pressed against inclined faces 16 that comprise the arms 2,3 at their ends fixed to the bracelet, the rod 10 of the central part 1 which is housed between the end faces 17 of these ends arms 2.3.

Lorsque les bras 2,3 sont en position fermée et verrouillée, ces bras sont de plus maintenus par les pans inclinés 12 de la tige 10 venant au contact des pans inclinés 16 des deux bras 2,3 et ceux-ci ne peuvent pas s'écarter de la partie centrale du fermoir 1.When the arms 2, 3 are in the closed and locked position, these arms are more held by the inclined faces 12 of the rod 10 coming into contact with the sides inclined 16 of the two arms 2,3 and these cannot deviate from the part clasp center 1.

Pour ouvrir le fermoir il faut d'abord le déverrouiller en déplaçant le poussoir 8 contre l'action du ressort 22 des verrous. Lorsque le poussoir bute contre le fond du logement 9, la tête des vis 14 se situe dans le plan de la face latérale des bras 2,3 faisant face à la partie centrale 1 du fermoir et les organes de verrouillage 23 sont alors rétractés dans les bras 2, 3. Dans cette position déverrouillée les bras 2,3 peuvent être librement pivotés sur leur axe 4 provoquant l'ouverture du fermoir.To open the clasp, you must first unlock it by moving the pusher 8 against the action of the spring 22 of the latches. When the pusher abuts against the bottom of the housing 9, the head of the screws 14 is located in the plane of the lateral face of the arms 2,3 facing the central part 1 of the clasp and the locking members 23 are then retracted into the arms 2, 3. In this unlocked position the arms 2.3 can be freely pivoted on their axis 4 causing the opening of the clasp.

La face latérale de la partie centrale 1 sur laquelle débouchent les évidements 15 comporte encore des creusures 24 dont le fond incliné provoque lors de la fermeture du fermoir, soit du rabat des bras 2,3 vers la partie centrale 1 du fermoir, la rétraction des organes de verrouillage 23 dans les douilles 21 jusqu'à la fermeture complète du fermoir où ces organes de verrouillage pénètrent dans les évidements 15 en repoussant les vis 14 et donc le poussoir 8, et verrouillent le fermoir en position fermée.The lateral face of the central part 1 on which the recesses 15 also have recesses 24 whose inclined bottom causes when the clasp is closed, i.e. from the flap of the arms 2,3 towards the central part 1 of the clasp, the retraction of the locking members 23 in the sockets 21 until the clasp is completely closed where these locking members penetrate in the recesses 15 by pushing the screws 14 and therefore the pusher 8, and lock the clasp in the closed position.

Dans une variante le fermoir pourrait ne comporter qu'un bras d'une longueur correspondant à celle de la partie centrale. Le bracelet serait fixé à l'extrémité libre de la partie centrale et à l'extrémité libre du bras unique. Les organes de verrouillage seraient montés tous deux dans la partie centrale du bras unique, où il n'y aurait qu'un seul organe de verrouillage.In a variant, the clasp could have only one arm of a length corresponding to that of the central part. The bracelet would be attached to the free end of the central part and the free end of the single arm. The locking devices would both be mounted in the central part of the arm single, where there would be only one locking member.

De nombreuses variantes du fermoir peuvent être prévues. La forme extérieure du fermoir peut être quelconque, la longueur des bras peut également varier. De même, la forme du poussoir peut être différente ainsi que celle des organes de retenue. Les bras peuvent être assemblés à la partie centrale du bracelet de toutes façons désirées. Many variations of the clasp can be provided. The form external of the clasp can be any, the length of the arms can also vary. Similarly, the shape of the pusher can be different as well as that of the retainers. The arms can be assembled at the central part of the bracelet anyway desired.

Le nombre d'organes de verrouillage par bras peut également varier. La retenue du poussoir n'est pas forcément en forme de queue d'aronde mais peut présenter la forme d'un T ou une autre forme. Le fermoir peut être plat ou incurvé ou encore présenter une autre forme.The number of locking members per arm can also vary. The pusher retainer is not necessarily dovetail-shaped but can present the shape of a T or another shape. The clasp can be flat or curved or present another form.

Ce fermoir présente de très nombreux avantages par rapport aux fermoirs existant dont les principaux sont énumérés ci-après.This clasp has many advantages over clasps the main ones of which are listed below.

Le fermoir est simple tant pour sa fabrication que pour sa manipulation par l'usager.The clasp is simple both for its manufacture and for its handling by the user.

De par sa conception, la section de la partie centrale et du ou des bras du fermoir peut être augmentée par rapport à un fermoir déployant existant tout en restant dans un même encombrement. Ceci augmente la robustesse et la durabilité du fermoir.By design, the section of the central part and of the arm (s) of the clasp can be increased compared to an existing folding clasp while remaining in the same space. This increases the robustness and the durability of the clasp.

Pour l'usager, l'accès au poussoir est facilité, il ne déborde plus du bracelet puisque la partie centrale du fermoir est décalée latéralement.For the user, access to the pusher is facilitated, it no longer overflows the bracelet since the central part of the clasp is offset laterally.

L'action de fermeture du fermoir est dissociée de l'action de verrouillage. En fait ce verrouillage intervient uniquement lorsque les bras atteignent leur position de fermeture parallèle à la partie centrale du fermoir.The closing action of the clasp is dissociated from the locking action. In does this locking only occurs when the arms reach their position closure parallel to the central part of the clasp.

Le verrouillage s'effectue par des organes de verrouillage indépendants de la forme, de la longueur et de l'élasticité des bras du fermoir et de sa partie centrale. La force de fermeture est très grande, elle est indépendante de la force de rappel des ressorts des verrous. La position verrouillée est indépendante de la fermeture.Locking is effected by locking members independent of the shape, length and elasticity of the clasp arms and its part central. The closing force is very large, it is independent of the force of the lock springs. The locked position is independent of the closing.

L'ouverture du fermoir se fait à l'aide d'un seul poussoir simple, ne comportant pas de ressorts, poussoir qui rétracte les verrous. Le retour du poussoir en position de verrouillage se fait automatiquement à l'aide des ressorts des verrous lors de la fermeture du fermoir. Le verrouillage est assuré automatiquement. The clasp is opened using a single simple button, do not with no springs, push button which retracts the locks. The return of push in the locking position is done automatically using the springs locks when closing the clasp. Locking is assured automatically.

En position fermée, les bras sont guidés et maintenus de façon précise dans leurs positions par un organe de maintien solidaire de la partie centrale du fermoir.In the closed position, the arms are precisely guided and held in their positions by a holding member secured to the central part of the clasp.

Les bras sont de préférence assemblés uniquement par un axe lisse qui a une tête à une extrémité et dont l'autre extrémité est soudée sur le bras ou la partie centrale par exemple par un soudage au laser. Une telle construction est très robuste et fiable. Elle ne comporte pas de vis pouvant se dévisser à la longue.The arms are preferably assembled only by a smooth axis which has a head at one end and the other end of which is welded to the arm or the central part for example by laser welding. Such a construction is very robust and reliable. It does not have screws that can be unscrewed in the long run.

La longueur des bras n'a plus d'importance dans la fonction de verrouillage mais dépend uniquement du déployement désiré pour le tour de poignet. Par l'utilisation de verrous on exclut l'utilisation de l'élasticité des bras et peut donc les rendre plus robustes.Arm length no longer matters in the locking function but depends only on the desired deployment for the wrist circumference. Through the use of bolts excludes the use of the elasticity of the arms and can therefore make it more robust.

La force nécessaire à la fermeture du fermoir dépend uniquement de la force des ressorts des verrous et de la pente des creusures inclinées provoquant le rétractement des verrous. Cette force peut être faible. La force d'ouverture est donnée uniquement par la force des ressorts de verrous. Cette force de fermeture et d'ouverture est indépendante de la force de verrouillage qui est beaucoup plus grande et déterminée uniquement par le cisaillement entre les verrous et la partie centrale du fermoir.The force required to close the clasp depends solely on the strength of the lock springs and the slope of the inclined recesses causing the retraction of the locks. This force may be weak. The opening force is given only by the force of the lock springs. This closing force and opening is independent of the locking force which is much more large and determined only by the shear between the latches and the part central clasp.

La force de verrouillage ne nécessite aucun réglage, elle peut être aussi grande que l'on veut et n'intervient pas dans le maniement du fermoir. Il n'y a donc pas besoin de régler cette force de verrouillage.The locking force does not require any adjustment, it can also be as large as you want and does not interfere with the handling of the clasp. So there is no need to adjust this locking force.

Le poussoir est situé dans un logement en forme de queue d'aronde évitant que celui-ci puisse être arraché et définissant sa course.The pusher is located in a dovetail-shaped housing avoiding that it can be torn off and defining its course.

Ce fermoir est donc facile à utiliser, simple à fabriquer et à monter, évite toute ouverture intempestive et est particulièrement robuste.This clasp is therefore easy to use, simple to manufacture and assemble, avoids any untimely opening and is particularly robust.
