Abstract

Device connecting the two ends of a chain, necklace, bracelet or earring (pierced ears) serving as a clasp. It comprises three parts: a hollow tube 1, having a notch 4 in which is lodged a pin 3 of the second cylindrical part 2, which while penetrating into the part 1 will be rotated in the direction of the arrow. This allows the spring 6 to lock the pin 3 in its housing. The rings 5 are the (optional) attachments to the necklaces, bracelets, earrings. The invention should be used as a clasp for necklaces, bracelets, chains and earrings made of gold, silver, or for a string of pearls or precious stones, or for jewellery.

Description

La présente invention concerne tous les bijoux n8cessitant un fermoir.The present invention relates to all jewelry n8cessitant a clasp.

Actuellement, le fermoir le plus utilisé est l'anneau ressort qui est disgracieux, important, lourd et qui nécessite souvent une chaine de sécurité supplémentaire, pour certains colliers et bracelets.Currently, the most used clasp is the spring ring which is unsightly, important, heavy and which often requires an additional safety chain, for certain necklaces and bracelets.

Ce fermoir permet, à lui seul, une sXcurité parfaite, et une dimension, une fois réalisé, faible, tràs important pour l'esthétique. De plus, son faible volume, permet la réalisation de bélières plus réduites, sur des pendentifs avec des pierres, par exemple, et quelquefois l'on peut supprimer la dite bXlière et la remplacer par un anneau fixe, sur le pendentif, ce qui allège considérablement l'aspect de l'ensemble; sur certains pendentifs et m8dailles, les b8li8res sont anormalement hautes pour le passage d'un anneau ressort actuel. D'autre part, il est d'une manipulation, aisée, plus facile que pour les modéles actuellement connus.Ce fermoir, rXalisX en or, pèse pour le plus petit modèle : 0,20 gramme et mesure 7mm de long et 12mm de diamètre ce qui permet une esthétique parfaite.This clasp allows, by itself, perfect safety, and a dimension, once made, low, very important for aesthetics. In addition, its small volume, allows the realization of smaller rings, on pendants with stones, for example, and sometimes we can remove the said bXlière and replace it with a fixed ring, on the pendant, which lightens considerably the appearance of the whole; on some pendants and medals, the b8li8res are abnormally high for the passage of a current spring ring. On the other hand, it is easy to handle, easier than for currently known models. This clasp, rXalisX in gold, weighs for the smallest model: 0.20 gram and measures 7mm long and 12mm in diameter which allows a perfect aesthetic.

Actuellement, ceux en circulation pèsnt, pour le plus petit modèle, de 0,40 à 0,50 gramme; au cours actuel de l'or, celà est très important. Il existe un verrouillage similaire dans la douille d'Edison mais il est double et pour un contact dlec- trique.Currently, those in circulation weigh, for the smallest model, from 0.40 to 0.50 grams; at the current price of gold, this is very important. There is a similar lock in the Edison socket but it is double and for electrical contact.

L'objet de l'invention comporte : une pince cylindrique pos séant un ergot, qui va se verrouiller dans l'encoche du tube creux, et qui sera maintenue par le ressort en pression. Plusieurs exemplaires de l'invention, à titre de prototype sont proposés et ont donné entière satisfaction tant à l'emploi qu'd l'aspect. Les dessins annexés, illustrent à titre d'exemple, un mode de réalisation du dispositif à la présente invention, dans lesquels la figure 1 représente la pièce creuse, la figure 2 la pièce malte, la figure 3 une vue en perspective.The object of the invention comprises: a cylindrical clamp pos seing a lug, which will lock in the notch of the hollow tube, and which will be maintained by the spring under pressure. Several copies of the invention, as a prototype are offered and have given complete satisfaction both in use and appearance. The accompanying drawings illustrate by way of example an embodiment of the device according to the present invention, in which FIG. 1 represents the hollow part, FIG. 2 the malt part, and FIG. 3 a perspective view.

Lorsque l'on manipule la pièce cylindrique (2) dans le tube creux (1) l'on procède à un verrouillage de l'ergot (3) dans l'encoche (4) un ressort (6) permet un pression destinée à retenir l'ergot (3) dans le fond de l'encoche (4).When handling the cylindrical part (2) in the hollow tube (1), the lug (3) is locked in the notch (4) a spring (6) allows a pressure intended to retain the lug (3) in the bottom of the notch (4).

Le fermoir, objet de l'invention, peut trie utilisé pour tous les bijoux or, demandant une fermeture jolie et pratique, d'un coût peu élevé; il peut s'appliquer aussi aux bijoux en argent en plaqué et à la bijouterie fantaisie. The clasp, object of the invention, can be used for all gold jewelry, requiring a pretty and practical closure, at a low cost; it can also be applied to silver plated jewelry and costume jewelry.
