Description

La présente invention concerne un fermoir pour chaines constitué d'un fourreau et d'un élément d'accrochage susceptible de coulisser dans ce fourreau entre une position d'ouverture et une position de fermeture.The present invention relates to a chain clasp consisting of a sheath and a hooking element capable of sliding in this sheath between an open position and a closed position.

Dans le type le plus courant des fermoirs actuellement utilisés, le fourreau est constitué d'un anneau creux, partiellement ouvert, dans lequel coulisse une tige courbe poussée par un ressort. Cette tige est manoeuvrable par un téton qui lui est solidaire et qui permet, en la ramenant et en la maintenant à l'arrière, d'ouvrir l'anneau.In the most common type of clasps currently used, the sheath consists of a hollow ring, partially open, in which slides a curved rod pushed by a spring. This rod is operable by a stud which is integral with it and which allows, by bringing it back and holding it at the rear, to open the ring.

Ce fermoir, assez ancien, dit "anneau à ressort", présente divers inconvénients.This quite old clasp, called "spring ring", has various drawbacks.

En premier lieu, sa forme arrondie rend difficile son maintien sur la tranche, entre le pouce et l'index, comme l'exige le fonctionnement de son mécanisme ; en effet, pendant que, dans cette position, l'ongle du pouce ramène et maintient le téton en arrière, il arrive très souvent que l'anneau glisse entre les doigts, se remette à plat et se referme. En second lieu, un anneau creux non fermé ne peut pas être d'une grande robustesse, et comme l'anneau d'emmaillement ne peut être soudé sur la chaîne sous peine de détremper le ressort, il est simplement refermé à la pince. L'habitude qu'ont certaines personnes de mordiller leur chaîne, produit un écrasement suffisant pour rendre l'anneau inutilisable. A cela s'ajoute que l'encrassement occasionné par le savon et les poussières contribue à détériorer un système que l'on ne peut pratiquement pas nettoyer. Enfin, esthétiquement, la forme de ce fermoir ne ne s'intègre pas du tout dans le profil d'une chaîne, en particulier quand elle est fine.Firstly, its rounded shape makes it difficult to hold it on the edge, between the thumb and forefinger, as required by the functioning of its mechanism; indeed, while, in this position, the thumbnail brings back and maintains the nipple behind, it very often happens that the ring slides between the fingers, returns to flat and closes. Secondly, an unclosed hollow ring cannot be very robust, and since the covering ring cannot be welded to the chain, otherwise the spring will become soaked, it is simply closed with pliers. The habit that some people have of biting their chain produces enough crushing to make the ring unusable. In addition, the fouling caused by soap and dust contributes to the deterioration of a system that can hardly be cleaned. Finally, aesthetically, the shape of this clasp does not fit at all into the profile of a chain, especially when it is fine.

L'invention à pour but d'éliminer ces inconvénients, but qui est atteint en ce sens qu'elle apporte un fermoir dans lequel l'élément d'accrochage comporte, d'une part, une tête d'accrochage formée d'une première et d'une seconde mâchoires et, d'autre part, au moins une lame de ressort qui est réunie à la première machoîre et tend a l'écarter de la seconde pour ouvrir la tête d'accrochage, le fourreau permettant ou s'opposant à cette ouverture selon la position de l'élément d'accrochage par rapport au fourreau.The invention aims to eliminate these drawbacks, which goal is achieved in that it provides a clasp in which the fastening element comprises, on the one hand, a fastening head formed of a first and a second jaw and, on the other hand, at least one leaf spring which is joined to the first jaw and tends to move it away from the second to open the hooking head, the sheath allowing or opposing at this opening according to the position of the hooking element relative to the sheath.

Cette structure élimine les difficultés de préhension et de manoeuvre du fermoir puisqu'il suffit de faire coulisser le fourreau et l'élément d'accrochage l'un par rapport à l'autre pour amener cet élément en position d'ouverture et ouvrir les machoires de la tête d'accrochage. A la différence de l'anneau à ressort, ces mâchoires ne se referment pas d'elles-mêmes si le fermoir glisse des doigts mais restent béantes tant que l'on ne fait pas coulisser l'élément d'accrochage dans le fourreau pour l'amener en position de fermeture.This structure eliminates the difficulties of gripping and maneuvering the clasp since it suffices to slide the sleeve and the attachment element relative to each other to bring this element into the open position and open the jaws of the attachment head. Unlike the spring ring, these jaws do not close by themselves if the clasp slides with your fingers but remain open until you slide the hooking element into the sheath for the 'bring it to the closed position.

Dans une forme d'exécution de l'invention, la lame de ressort réunie à la première mâchoire et une.languette réunie à la seconde machôire sont reliées, à leur extrémité opposée à la tête d'accrochage, par un pont susceptible d'être enfilé dans un anneau de bout de chaîne.In one embodiment of the invention, the spring leaf joined to the first jaw and a . tongue joined to the second jaw are connected, at their end opposite to the attachment head, by a bridge capable of being threaded in a ring at the end of the chain.

Ainsi l'élément d'accrochage coulissant dans le fourreau peut servir à "l'ancrage" des deux anneaux de bout de chaîne, l'un étant énfilé à demeure sur le pont et l'autre étant retenu, de manière amovible, dans la tête d'accrochage.Thus the hooking element sliding in the sheath can be used for "anchoring" the two chain end rings, one being permanently threaded on the bridge and the other being detachably retained in the hanging head.

De préférence, le fermoir selon l'invention comprend deux lames de ressort réunies respectivement aux deux machoîres et qui tendent à les écarter, auquel cas la languette précitée est une lame de ressort.Preferably, the clasp according to the invention comprises two leaf springs joined respectively to the two jaws and which tend to separate them, in which case the aforementioned tongue is a leaf spring.

Pour empêcher la désolidarisation du fourreau et de l'élément d'accrochage, il est prévu un organe d'arrêt constitué, éventuellement, d'une goupille disposée entre la lame de ressort et la languette, et rivée sur les faces opposées du fourreau.To prevent separation of the sheath and the attachment element, a stop member is provided, possibly consisting of a pin disposed between the spring leaf and the tongue, and riveted on the opposite faces of the sheath.

A des fins de blocage, l'élément d'accrochage comporte un logement susceptible de venir en prise avec la goupille, en position de fermeture.For locking purposes, the hooking element includes a housing capable of coming into engagement with the pin, in the closed position.

Avantangeusement, l'une au moins des mâchoires de la tête d'accrochage comporte au voisinage de sa zone de jonction avec la lame du ressort, ou de la languette, une projection profilée de manière à définir, en position de fermeture, avec l'autre mâchoire, une'pièce susceptible d'encercler la partie d'un anneau de bout de chaîne retenu par les mâchoires.Advantageously, at least one of the jaws of the attachment head comprises, in the vicinity of its junction zone with the leaf of the spring, or of the tongue, a profiled projection so as to define, in the closed position, with the another jaw, a piece capable of encircling the part of a chain end ring retained by the jaws.

Le logement susceptible de venir en prise avec la goupille peut alors être prévu au niveau de la jonction entre la projection et la lame\de ressort, ou la languette.The housing capable of coming into engagement with the pin can then be provided at the junction between the projection and the leaf / spring, or the tongue.

L'invention est décrite en détail ci-après en référence au dessin annexé dans lequel :

  • - la figure 1 est une vue de dessus d'une forme d'exécution du fermoir selon l'invention,
  • - la figure 2 est une vue de côté de ce même fermoir,
  • - les figures 3 et 4 sont des coupes transversales du fermoir respectivement en position fermée et en position ouverte,
  • - la figure 5 est une vue en bout du fermoir, montrant la tête d'accrochage, et
  • - les figures 6 et 7 illustrent respectivement le mode d'ouverture et de fermeture du fermoir.
The invention is described in detail below with reference to the accompanying drawing in which:
  • - Figure 1 is a top view of an embodiment of the clasp according to the invention,
  • FIG. 2 is a side view of this same clasp,
  • FIGS. 3 and 4 are cross sections of the clasp respectively in the closed position and in the open position,
  • FIG. 5 is an end view of the clasp, showing the hooking head, and
  • - Figures 6 and 7 respectively illustrate the opening and closing mode of the clasp.

Si l'on se réfère aux figures 1 à 5, on voit que le fermoir selon l'invention comprend un fourreau 1 et un élément d'accrochage 2 susceptibles de coulisser l'un par rapport à l'autre, leur désolidarisation étant toutefois empêchée par une goupille 3 rivée sur les faces opposées du fourreau 1.If we refer to Figures 1 to 5, we see that the clasp according to the invention comprises a sheath 1 and a fastening element 2 capable of sliding relative to each other, their separation being however prevented by a pin 3 riveted on the opposite faces of the sleeve 1.

Il ressort des figures 3 et 4 que l'élément d'accrochage 2 est composé de deux lames de ressort 4a et 4b réunies, à une de leurs extrémités, à une machoîre, respectivement 5a et 5b, et, à leur autre extrémité, à un pont 6. Les deux mâchoires 5a et 5b forment une tête d'accrochage 7 dimensionnée de telle sorte que les surfaces 7a et 7b coulissent avec un frottement doux sur les faces internes du fourreau 1. La machoîre 5a comporte une projection 8 profilée, d'une part, de manière à définir, en position de fermeture, une zone sensiblement circulaire avec la face interne de la mâchoire 5b et, d'autre part, un logement 9 à la jonction avec la lame de ressort 4a, lequel logement 9 est adapté à venir en prise avec la goupille 3, en position de fermeture. Le fourreau 1 comporte, quant à lui, deux encoches 10 et 11 dégageant l'espace nécessaire aux anneaux de bout de chaîne auxquels est réuni le fermoir.It appears from FIGS. 3 and 4 that the fastening element 2 is composed of two spring leaves 4a and 4b joined, at one of their ends, to a jaw, respectively 5a and 5b, and, at their other end, to a bridge 6. The two jaws 5a and 5b form a hooking head 7 dimensioned so that the surfaces 7a and 7b slide with gentle friction on the internal faces of the sleeve 1. The jaw 5a comprises a profiled projection 8, d on the one hand, so as to define, in the closed position, a substantially circular area with the internal face of the jaw 5b and, on the other hand, a housing 9 at the junction with the spring leaf 4a, which housing 9 is suitable for engaging with pin 3, in the closed position. The sheath 1 comprises, meanwhile, two notches 10 and 11 freeing the space necessary for the chain end rings to which the clasp is joined.

Le dispositif est utilisé comme suit :

  • Pour permettre l'ancrage à demeure d'un des anneaux de bout de chaîne 12 (figures 6 et 7), le fermoir est fourni assemblé mais sans que la goupille 3 soit rivée. Il est ainsi possible au monteur d'enlever cette goupille 3 et de faire coulisser l'élément d'accrochage 2 hors du fourreau 1 pour pouvoir enfiler sur la machoîre 5b, la lame de ressort 4b, puis le pont 6, l'anneau 12 préalablement fermé et soudé (un tel soudage n'étant pas possible dans le cas de l'anneau à ressort, comme on l'a vu plus haut). L'élément d'accrochage 2 est ensuite remis en place dans le fourreau 1. Une fois la goupille 3 réintroduite dans les trous prévus à cet effet et non représentés, le monteur.la rive, empêchant ainsi la désolidarisation du fourreau et de l'élément d'accrochage.
The device is used as follows:
  • To allow permanent anchoring of one of the chain end rings 12 (FIGS. 6 and 7), the clasp is supplied assembled but without the pin 3 being riveted. It is thus possible for the fitter to remove this pin 3 and to slide the fastening element 2 out of the sheath 1 so as to be able to thread on the jaw 5b, the spring leaf 4b, then the bridge 6, the ring 12 previously closed and welded (such welding is not possible in the case of the spring ring, as seen above). The fastening element 2 is then replaced in the sleeve 1. Once the pin 3 is reintroduced into the holes provided for this purpose and not shown, the monteur.la rive, preventing the separation of the sleeve and the fastening element.

Pour réunir le second anneau de bout de chaîne 13 au fermoir, il suffit de faire coulisser suffisammert l'élément d'accrochage 2 hors du fourreau 1 pour en dégager les surfaces 7a et 7b de la tête d'accrochage 7. La force exercée par les lames de ressort 4a et 4b ne se trouvant plus contrariée par le fourreau 1, les machoîres 5a et 5b peuvent alors s'écarter en ouvrant la tête d'accrochage 7 (figures 4 et 6). Le coulissement de l'élément d'accrochage 2 est limité, dans cette direction, par la présence de l'anneau 12 qui vient buter sur le fond de l'encoche 10.To join the second chain end ring 13 to the clasp, it suffices to slide the hooking element 2 sufficiently out of the sheath 1 to release the surfaces 7a and 7b from the hooking head 7. The force exerted by the spring leaves 4a and 4b no longer being thwarted by the sheath 1, the jaws 5a and 5b can then move aside by opening the hooking head 7 (FIGS. 4 and 6). The sliding of the fastening element 2 is limited, in this direction, by the presence of the ring 12 which abuts on the bottom of the notch 10.

Le porteur du bijou introduit alors l'anneau de bout de chaîne 13 entre les mâchoires 5a et 5b, dans l'espace défini par la face interne de ces mâchoires et par la projection 8, puis réintroduit l'élément d'accrochage 2 dans le fourreau 1, ramenant ainsi les surfaces 7a et 7b de la tête d'accrochage 7, refermée, en contact avec les parois internes du fourreau 1 (figure 3).The wearer of the jewel then introduces the chain end ring 13 between the jaws 5a and 5b, in the space defined by the internal face of these jaws and by the projection 8, then reintroduces the attachment element 2 in the sheath 1, thus bringing back the surfaces 7a and 7b of the hooking head 7, closed, in contact with the internal walls of the sheath 1 (FIG. 3).

Comme on le voit, la projection 8 définit en position de fermeture et avec les machoires 5a et 5b un espace circulaire entourant la partie de l'anneau de bout de chaîne 13 emprisonné dans le fermoir. Le coulissement vers la position de fermeture de l'élément d'accrochage 2 est obtenu soit en poussant avec l'anneau de bout de chaîne 13 sur la projection 8 suivant la flèche Fl, soit, en maintenant la chaîne dans la paume de la main, en poussant sur le fourreau 1 avec le pouce et l'index comme l'indiquent les flèches F2 (figure 6). Le coulissement est limitée par la goupille 3 qui vient en prise avec le logement 9 prévu à la jonction entre la projection 9 et la lame de ressort 4a. Pour ouvrir le fermoir, il suffit de maintenir le fourreau 1 entre le pouce et l'index et de tirer sur la partie de chaîne reliée à l'anneau 13, comme le montre les flèches F3 de la figure 7.As can be seen, the projection 8 defines in the closed position and with the jaws 5a and 5b a circular space surrounding the part of the chain end ring 13 trapped in the clasp. The sliding towards the closed position of the hooking element 2 is obtained either by pushing with the chain end ring 13 on the projection 8 in the direction of arrow Fl, or, by keeping the chain in the palm of the hand , pushing on the sheath 1 with the thumb and forefinger as indicated by the arrows F2 (FIG. 6). The sliding is limited by the pin 3 which engages with the housing 9 provided at the junction between the projection 9 and the leaf spring 4a. To open the clasp, just hold the sheath 1 between your thumb and forefinger and pull on the part of the chain connected to the ring 13, as shown by the arrows F3 in FIG. 7.

Comme on le voit, la forme du fermoir selon l'invention permet une manipulation très aisée tout en s'harmonisant parfaitement avec le profil des chaînes, mêmes les plus fines.Il n'y a pas, pour l'utilisation de ce fermoir, de position particulière à observer puisque l'on pousse sur le fourreau dans un sens pour le fermer et dans l'autre sens pour l'ouvrir.As we can see, the shape of the clasp according to the invention allows very easy handling while harmonizing perfectly with the profile of the chains, even the finest. There is not, for the use of this clasp, of particular position to observe since one pushes on the sheath in one direction to close it and in the other direction to open it.

L'élément d'accrochage 2, qui est l'élément soumis aux efforts de traction ne comporte aucun point de rupture plus faible que la chaîne à laquelle il est destiné. La conception de ce dispositif en fait un système compact très robuste qui, de plus, se démonte aisément afin de le remonter sur un autre bijou ou de le nettoyer s'il en était besoin. Il-suffit, en effet, de retirer la goupille 3 pour libérer l'élément 2 et de remonter l'ensemble comme décrit ci-dessus.The attachment element 2, which is the element subjected to the tensile forces, has no weaker breaking point than the chain for which it is intended. The design of this device makes it a very robust compact system which, moreover, is easily disassembled in order to reassemble it on another piece of jewelry or to clean it if necessary. It suffices, in fact, to remove the pin 3 to release the element 2 and reassemble the assembly as described above.

Il est bien entendu que l'invention n'est pas limitée au fermoir décrit et représenté. Celui-ci peut, en effet, varier dans ses dimensions et dans sa . forme Par exemple, au lieu d'être réalisé à partir d'un tube de section rectangulaire, le fourreau pourrait l'être à partir d'un tube de section circulaire ou carrée. Il est également clair que le fermoir peut aussi bien être réuni à des anneaux de bout de chaîne circulaires que polygonaux.It is understood that the invention is not limited to the clasp described and shown. This can, indeed, vary in its dimensions and in its. shape For example, instead of being made from a tube of rectangular section, the sheath could be made from a tube of circular or square section.
