Description

Fermoir. 11 existe dejä des fermoirs pour montres- bracelets, bijoux, etc., dann lesquels sout fixees, par exemple par une operation de couture, les extremites d'un cordon simple ou multiple servant de lieh. Clasp. There are already clasps for wristwatches, jewelry, etc., in which are fixed, for example by a sewing operation, the ends of a single or multiple cord serving as a binder.

Le but de la presente invention est un perfectionnement qui simplifie la fixation des extremites du cordon lors dun remplace- ment et permet de rattraper aussi 1'allonge- ment qui se manifeste e, 1'usage, en liberant )es extremites de fixation du cordon, en les coupant dune longueur convenable et en les remettant en place. The object of the present invention is an improvement which simplifies the fixing of the ends of the cord during a replacement and also makes it possible to compensate for the elongation which manifests itself during use, by releasing the fixing ends of the cord. , cutting them to a suitable length and putting them back in place.

Lobjet de la presente invention est un fermoir pour cordon de fixation de pike de bijouterie, caracterise en ce qu'il comporte deux paires de mächoires douees d'elasticite servant ä saisir les extremites du cordon dont 1e mors principal de chaque paire de mä- choires, qui fait Partie du corps du fermoir. est articule avec 1e mors conjugue, 1'elasticite des mAchoires kant utilisee pour leur blo- cage mutuel. The object of the present invention is a clasp for a jewelry pike attachment cord, characterized in that it comprises two pairs of elastic jaws serving to grip the ends of the cord, the main jaw of each pair of jaws , which is part of the body of the clasp. is articulated with the joint jaw, the elasticity of the jaws kant used for their mutual blocking.

Le dessin annexe represente, ä eitre d'exemple, une forme d'execution du fermoir selon 1'invention. The appended drawing shows, by way of example, one embodiment of the clasp according to the invention.

La fig. 1 est une coupe longitudinale me- diane du fermoir auquel sont fixees les extre- mit6s 9 du cordon. fig. 1 is a median longitudinal section of the clasp to which the ends 9 of the cord are fixed.

La fig. 2 est une coupe transversale sui- vant la ligne 1I-II de la fig. 1. fig. 2 is a cross section along line II-II of FIG. 1.

La fig. 3 est une perspective montrant ]es deux paires de mächoires, ainsi que (en traits mixtes) les extremites du cordon en Prise dans une mächoire. La fig. 1 montre les mors principaux 1 et 2: 1e mors 1 est entaille dune encoche recta,ngulaire 12 dans laquelle vient buter la patte 13 correspondante du mors 2, les empechant ainsi de glisser 1'un sur 1'autre sous 1'effet de la traction longitudinale des extremites 9 du cordon. Le mors. 2 dont an voit 1e dkail ä. la fig. 3 s'ajuste sur 1e mors conjugue 6, gräte aux asperites 10 qui p6ne- trent par Pression dans les cuvettes 11, et aux becs 5 contre lesquels viennent buter les encoches 7. Le mors 1 differe encore du mors 2 par 1'orifice 4 dont il est perce. La. lan- guette 8 (fig. 1, 2 et 3) decoupee selon un triangle dans 1e dos du mors 6 et pliee ä angle droit, assujettit les extremites du cor- don, alors que 1e crochet 3 sert de butee au bord de 1'orifice 4 (fig. 1) dann lequel il penetre. Le second mors conjugue que Fon voit en coupe dans la Partie drohe de la fig. 1 est different du Premier, ca,r il ne pos sAde pas de crochet 3 et sa languette est tour- n@e vers 1e haut. fig. 3 is a perspective showing the two pairs of jaws, as well as (in phantom) the ends of the cord engaged in a jaw. fig. 1 shows the main jaws 1 and 2: the first jaw 1 is notched with a recta, ngular notch 12 in which abuts the corresponding lug 13 of the jaw 2, thus preventing them from sliding one on the other under the effect of the longitudinal traction of the ends 9 of the cord. The bit. 2 of which an sees 1e dkail ä. fig. 3 fits on the combined jaw 6, thanks to the asperities 10 which penetrate by pressure into the cups 11, and to the beaks 5 against which the notches 7 abut. The jaw 1 still differs from the jaw 2 by the orifice 4 of which he is bored. The tongue 8 (figs. 1, 2 and 3) cut in the shape of a triangle in the back of the bit 6 and bent at a right angle, secures the ends of the cord, while the hook 3 serves as a stop at the edge of the jaw. 1'orifice 4 (Fig. 1) in which it enters. The second jaw conjugate that Fon sees in section in the right part of fig. 1 is different from the First, because it does not have a hook 3 and its tongue is turned upwards.

RTI ID="0001.0272" WI="8" HE="4" LX="1105" LY="1710"> Dans la fig. 2. an a represente deux asperites 10 engagees dans deux cuvettes 11 comme Parties mäles et femelles situees res- pectivement sur un mors principal et un mors conjugue. Il faut remarquer, en outre, que 1e mors prineipal 1 est ajuste ä frottement leger sur les cötes du mors conjugue 6. RTI ID="0001.0272" WI="8" HE="4" LX="1105" LY="1710"> In fig. 2. an has represented two asperities 10 engaged in two bowls 11 as male and female parts located respectively on a main jaw and a combined jaw. It should also be noted that the main jaw 1 is adjusted with light friction on the sides of the combined jaw 6.

La fig. 3 ne fait pas apparaitre d'ele- ments nouveaux, mais elle precise les den-, autres figures. fig. 3 does not reveal any new elements, but it specifies the den-, other figures.

Pour monter 1e cordon d'un töte, an enga- gera d'abord une de ses extremites dans un mors conjugué que l'on présentera ainsi garni de manière à engager les encoches dans les becs correspondants; on procédera à un pivo tement jusqu'à ce que les aspérités viennent occuper les cuvettes, grâce à l'élasticité d'an semble des différents mors. To mount the cord of a head, one will first engage one of its extremities in a conjugate jaw which will be presented thus furnished in such a way as to engage the notches in the corresponding jaws; one will proceed to a pivoting until the asperities come to occupy the basins, thanks to the elasticity of an seems of the various jaws.

Le fermoir s'ouvre facilement en introdui sant l'ongle entre le mors 6 et le mors 1 (fig. 2). The clasp opens easily by inserting the nail between jaw 6 and jaw 1 (fig. 2).

La construction des mors pourrait être réalisée plus ou moins différemment que dé crit sans sortir de l'invention, par exemple, on pourrait remplacer les aspérités et leurs cuvettes venues par coups de pointeaux par des arranzements équivalents. The construction of the jaws could be carried out more or less differently than described without departing from the invention, for example, one could replace the asperities and their cups coming by punching by equivalent arrangements.

CLAIM Clasp for cord for fastening a piece of jewelry, characterized in that it comprises two pairs of jaws endowed with elasticity serving to grip the ends of the cord, the main jaw of each pair of jaws, which is part of the body of the clasp. is articulated with the joint bit, the elasticity of the jaws being used for their mutual blocking. SUB-CLAIMS 1. Clasp according to claim, charac terized in that each main jaw is provided with a pair of beaks cooperating with a pair of notches of the joint jaw so as to form a common pivot axis.

2. Clasp according to claim, characterized in that each pair of jaws has two protrusions engaged in two corresponding cups to block said pair of jaws. d. Clasp according to claim, charac terized in that each conjugate jaw carries a tab cut out in the back. of the bit and bent at a right angle which is inserted like a wedge into the end of the cord, making it integral with the clasp.
