Description

La présente invention est relative à un fermoir à double sécurité pour relier les deux brins d'un bracelet, notamment d'un bracelet-montre.The present invention relates to a double safety clasp for connecting the two strands of a bracelet, in particular a watch bracelet.

Un fermoir dit de sécurité, en plus qu'il doit pouvoir être actionné avec facilité, doit répondre à au moins deux conditions fondamentales. D'abord, il doit permettre un premier accrochage aisé du bracelet sur le poignet de telle façon que tout danger de chute soit écarté pendant cette opération. Ensuite, une fois le bracelet définitivement fermé, tout mouvement du poignet, de la main, de l'action des vêtements recouvrant le poignet ne doit en aucun cas conduire à une ouverture intempestive du fermoir.A so-called safety clasp, in addition to being able to be actuated with ease, must meet at least two fundamental conditions. First, it must allow a first easy hanging of the bracelet on the wrist so that any danger of falling is avoided during this operation. Then, once the bracelet is finally closed, any movement of the wrist, of the hand, of the action of the clothing covering the wrist must in no case lead to an untimely opening of the clasp.

La première de ces conditions est réalisée au moyen d'un fermoir dit à portefeuille où chacun des brins du bracelet sont liés ensemble par deux segments articulés et rabattables l'un sur l'autre. La seconde de ces conditions est généralement remplie en utilisant diverses formes de fermetures à déclic.The first of these conditions is achieved by means of a so-called wallet clasp where each of the strands of the bracelet are linked together by two articulated segments which can be folded one over the other. The second of these conditions is usually met using various forms of snap closures.

Une telle construction répondant aux conditions précitées est décrite dans la demande de certificat d'utilité FR-A-2 478 970. On trouve ici deux segments articulés l'un à l'autre et repliables l'un sur l'autre, les extrémités libres de chacun des segments étant attachés à chacun des brins du bracelet respectivement. Après avoir amené en superposition les deux segments, on force un crochet solidaire d'une des extrémités libres à pénétrer dans un dispositif de blocage solidaire de l'autre extrémité libre. Ce dispositif comprend une détente actionnable manuellement et coulissant dans un logement contre la force de rappel d'un ressort. Le logement et la détente comportent chacun un trou qui sont légèrement désaxés l'un par rapport à l'autre. Quand le crochet pénètre dans ces trous, il déplace la détente jusqu'à ce que la tranche de cette dernière se trouve en face de l'échancrure du crochet. A ce moment, la détente est rappelée en position où elle verrouille le crochet. Pour libérer le crochet seule une action du doigt sur la détente peut entraîner l'ouverture du fermoir. En cela, le dispositif décrit répond à la sécurité qu'on s'est donné d'atteindre car tout mouvement intempestif ne parviendra pas à ouvrir le fermoir. Il présente cependant l'inconvénient d'utiliser deux segments plus ou moins rigides, ce qui est peu confortable au poignet, peu esthétique en même temps que mal adapté à un bracelet aux lignes raffinées et souvent réalisé en métal précieux.Such a construction meeting the aforementioned conditions is described in the application for a certificate of utility FR-A-2 478 970. Here there are two segments articulated to one another and foldable one over the other, the ends free of each of the segments being attached to each of the strands of the bracelet respectively. After having brought the two segments into superposition, a hook secured to one of the free ends is forced into a blocking device secured to the other free end. This device includes a manually actuated trigger sliding in a housing against the return force of a spring. The housing and the trigger each have a hole which are slightly offset from one another. When the hook enters these holes, it moves the trigger until the edge of the latter is opposite the notch of the hook. At this time, the trigger is returned to the position where it locks the hook. To release the hook, only a finger action on the trigger can open the clasp. In this, the device described responds to the security that we have given ourselves to achieve because any untimely movement does not will fail to open the clasp. However, it has the disadvantage of using two more or less rigid segments, which is uncomfortable on the wrist, unattractive at the same time as ill-suited to a bracelet with refined lines and often made of precious metal.

Pour remédier à ces inconvénients, le fermoir selon la présente invention évite l'utilisation des deux segments cités tout en présentant une excellente sécurité. Pour ce faire, il est caractérisé en ce que l'extrémité du premier brin du bracelet comporte un premier élément de fermeture articulé autour d'un premier axe perpendiculaire à la direction longitudinale du bracelet pour emprisonner l'extrémité du second brin et un second élément de fermeture articulé autour d'un second axe s'étendant dans la direction longitudinale du bracelet, ledit second élément étant arrangé pour couvrir, une fois rabattu, ledit premier élément.To overcome these drawbacks, the clasp according to the present invention avoids the use of the two segments mentioned while having excellent safety. To do this, it is characterized in that the end of the first strand of the bracelet comprises a first closure element articulated around a first axis perpendicular to the longitudinal direction of the bracelet to trap the end of the second strand and a second element closure articulated around a second axis extending in the longitudinal direction of the bracelet, said second element being arranged to cover, once folded, said first element.

On connaît déjà du brevet CH 623 466 un fermoir muni d'un élément de fermeture ayant une articulation parallèle à la longueur du bracelet. Il s'agit cependant là d'un fermoir pour lien souple, où le brin libre du bracelet doit être accroché sur un téton avant de rabattre ledit élément de fermeture. Cette façon de faire ne garantit pas toutefois un accrochage sûr du bracelet avant que soit rabattu l'élément de fermeture de sorte que le bracelet risque de tomber.Already known from patent CH 623 466 a clasp provided with a closure element having an articulation parallel to the length of the bracelet. However, this is a clasp for flexible link, where the free end of the bracelet must be hung on a stud before folding said closure element. However, this does not guarantee secure attachment of the bracelet before the closure element is folded down so that the bracelet may fall.

L'invention sera comprise maintenant à l'aide de la description qui suit et des dessins qui l'illustrent à titre d'exemple.

  • La figure montre une vue en perspective du fermoir ouvert selon l'invention auquel est attaché un bracelet métallique à maillons.
  • La figure 2 est une vue en coupe du dispositif de blocage selon la ligne II-II de la figure 1.
  • La figure 3 est une vue en coupe de l'élément de fermeture selon la ligne III-III de la figure 1.
The invention will now be understood with the aid of the description which follows and of the drawings which illustrate it by way of example.
  • The figure shows a perspective view of the open clasp according to the invention to which a metallic link bracelet is attached.
  • FIG. 2 is a sectional view of the locking device according to line II-II of FIG. 1.
  • FIG. 3 is a sectional view of the closure element along the line III-III of FIG. 1.

La figure 1 est une vue en perspective du fermoir selon l'invention. Le bracelet comprend deux brins 1 et 2 formés chacun d'une succession de maillons articulés l'un à l'autre. L'extrémité 5 du premier brin 1 porte un système 3 comportant un premier élément de fermeture 10 articulé autour d'un premier axe 7 qui est perpendiculaire à la direction longitudinale du bracelet. Cet élément est arrangé pour emprisonner l'extrémité 4 du second brin 2. Le système 3 comporte encore un second élément de fermeture 20 articulé autour d'un second axe 8 s'étendant dans la direction longitudinale du bracelet.Figure 1 is a perspective view of the clasp according to the invention. The bracelet includes two strands 1 and 2 each formed of a succession of links hinged to each other. The end 5 of the first strand 1 carries a system 3 comprising a first closure element 10 articulated around a first axis 7 which is perpendicular the longitudinal direction of the bracelet. This element is arranged to trap the end 4 of the second strand 2. The system 3 also comprises a second closing element 20 articulated around a second axis 8 extending in the longitudinal direction of the bracelet.

On va décrire maintenant une construction préférée de l'invention basée sur le principe énoncé ci-dessus.We will now describe a preferred construction of the invention based on the principle stated above.

Le premier élément de fermeture consiste en une languette 10 articulée autour d'une charnière 7 disposée perpendiculairement à la direction longitudinale du bracelet. Languette et charnière sont réalisées de telle sorte que la languette ne puisse pas se renverser vers l'arrière, sa position angulaire ouverte étant à peu près celle qui est représentée en figure 1. La charnière 7 est solidaire de l'extrémité 5 du brin 1 du bracelet. La languette 10 présente à son extrémité libre 11 un loqueteau 12. Ce loqueteau, après avoir rabattu la languette dans la direction du brin 1, coopère avec une nervure 13 portée par l'extrémité du bracelet pour cranter ainsi la languette en position fermée. La languette porte encore un rebord 15 qui servira à la débloquer, au moyen d'un ongle par exemple.The first closure element consists of a tongue 10 articulated around a hinge 7 arranged perpendicular to the longitudinal direction of the bracelet. Tongue and hinge are produced in such a way that the tongue cannot tip backwards, its open angular position being roughly that shown in FIG. 1. The hinge 7 is integral with the end 5 of the strand 1 of the bracelet. The tongue 10 has at its free end 11 a latch 12. This latch, after having folded the tongue in the direction of the strand 1, cooperates with a rib 13 carried by the end of the bracelet to thus notch the tongue in the closed position. The tongue also carries a rim 15 which will serve to unlock it, by means of a nail for example.

Comme cela apparaît sur la figure 1, l'extrémité 4 du second brin 2 est pourvue d'une ouverture rectangulaire 17 destinée à être enfilée sur la languette 10. On choisira pour l'ouverture 17 des longueurs 18 et largeurs 16 telles que l'extrémité 4 se centre parfaitement autour de la charnière 7. Une fois l'extrémité 4 en place, on rabat la languette, ce qui maintient le premier brin en liaison avec le second et constitue la première fermeture de sécurité présentée par le fermoir. Comme la languette ne peut pas se renverser en arrière et que d'autre part elle porte le loqueteau 12 dont on a parlé, on comprendra qu'une fois introduite l'ouverture 17 sur la languette 10, il ne sera plus possible à ladite ouverture de glisser hors de son siège.As shown in FIG. 1, the end 4 of the second strand 2 is provided with a rectangular opening 17 intended to be threaded on the tongue 10. For the opening 17, lengths 18 and widths 16 such that the end 4 is centered perfectly around the hinge 7. Once the end 4 in place, the tongue is folded down, which keeps the first strand in connection with the second and constitutes the first safety closure presented by the clasp. As the tongue cannot overturn back and on the other hand it carries the catch 12 which we have mentioned, it will be understood that once the opening 17 has been introduced on the tongue 10, it will no longer be possible at said opening to slide out of his seat.

Le second élément de fermeture comporte une plaque 20 articulée autour d'une charnière 8 disposée dans la direction longitudinale du bracelet ou, si l'on préfère, disposée perpendiculairement à la charnière 7. Lorsqu'on a rabattu la languette 10, on peut alors rabattre la plaque 20 par dessus la languette 10.The second closure element comprises a plate 20 articulated around a hinge 8 disposed in the longitudinal direction of the bracelet or, if preferred, disposed perpendicular to the hinge 7. When the tongue 10 has been folded down, it is then possible to fold the plate 20 over the tab 10.

La figure 1 montre que la plaque 20 est pourvue d'une excavation 21 dans laquelle vient se loger la languette 10, ceci dans le but de réduire au minimum la hauteur du fermoir. La plaque 20 porte en outre à son extrémité libre un crochet 22 apte à venir se cranter sur un dispositif de blocage 6.Figure 1 shows that the plate 20 is provided with an excava tion 21 in which is housed the tongue 10, this in order to minimize the height of the clasp. The plate 20 further carries at its free end a hook 22 capable of coming into contact with a locking device 6.

Le dispostif de blocage peut être réalisé de différentes façons. Une variante préférée est montrée dans les figures 1, 2 et 3. Ici, le dispositif de blocage 6 comprend une détente 25 actionnable manuellement et soumise à l'action d'un ressort 26. Le dispositif 6 et la détente 25 sont pourvus chacun d'un trou 23 et 24 respectivement. Au repos, les trous sont légèrement désaxés selon les axes désignés par a et a1. Le crochet 22 pénètre d'abord dans le trou 23 sur lequel il est centré. Quand il aborde le trou 24 de la détente 25, son nez 27 fait glisser la détente vers la droite jusqu'à ce que la tranche de ladite détente se trouve en face de l'échancrure 28 du crochet 22. A ce moment, la détente pénètre dans ladite échancrure rappelée qu'elle est par le ressort 26. La fermeture se trouve alors bloquée. Dès cet instant seule une manoeuvre exercée avec le doigt peut réouvrir le fermoir. Il s'agit là de la seconde fermeture de sécurité présentée par le fermoir.The blocking device can be achieved in different ways. A preferred variant is shown in FIGS. 1, 2 and 3. Here, the locking device 6 comprises a trigger 25 which can be actuated manually and subjected to the action of a spring 26. The device 6 and the trigger 25 are each provided with: 'a hole 23 and 24 respectively. At rest, the holes are slightly offset along the axes designated by a and a 1 . The hook 22 first enters the hole 23 on which it is centered. When it approaches the hole 24 of the trigger 25, its nose 27 slides the trigger to the right until the edge of said trigger is opposite the notch 28 of the hook 22. At this moment, the trigger penetrates into said recess recalled that it is by the spring 26. The closure is then blocked. From this moment only a maneuver exerted with the finger can reopen the clasp. This is the second safety closure presented by the clasp.

On notera que lors de la réouverture du fermoir, la première opération - qui pourrait être faite avec inadvertance - ne fait courir aucun danger de chute au bracelet puisqu'il faut encore débloquer la languette 10 pour séparer les brins 1 et 2. On a donc proposé un fermoir présentant une garantie maximum de sécurité tout en s'affranchissant de l'utilisation des segments rigides dont on a dit qu'ils sont peu agréables et inesthétiques.Note that when the clasp reopens, the first operation - which could be done inadvertently - poses no danger of the bracelet falling, since the tongue 10 must still be released to separate the strands 1 and 2. We therefore have proposed a clasp with a maximum guarantee of security while eliminating the use of rigid segments which have been said to be unpleasant and unsightly.

On mentionnera également que la face supérieure 29 de la plaque 20 peut porter des motifs décoratifs comme un monogramme ou des pierres précieuses et ceci dans le but de personnaliser et d'embellir le, bracelet.It will also be mentioned that the upper face 29 of the plate 20 can carry decorative patterns such as a monogram or precious stones, with the aim of personalizing and embellishing the bracelet.
