La présente invention a pour objet un porte-clés. On connaît déjà sur le marché une grande quantité de porte-clés, dont le mécanisme ou la forme se ressemblent trés souvent; on retiendra cependant une forme d'exécution connue se rapportant en particulier à un porte-clés qui comprend une boucle ouverte, dont les deux extrémités viennent se verrouiller dans une ouverture pratiquée dans un support, le verrouillage pouvant être ouvert au moyen d'une goupille ou d'un téton coulissant librement dans un alésage. The present invention relates to a key ring. We already know on the market a large quantity of key rings, whose mechanism or shape very often resemble each other; however, there is a known embodiment relating in particular to a key ring which includes an open loop, the two ends of which come to lock in an opening made in a support, the locking being able to be opened by means of a pin. or a nipple sliding freely in a bore.

Le principal désavantage de cette exécution réside dans le fait qu'il est nécessaire de sortir les deux extrémités de la boucle pour mettre ou enlever une clé avec, en plus, un mécanisme de verrouillage se remplissant d'impuretés contenues dans les poches et provoquant souvent un grippage lors de l'ouverture du porte-clés. The main disadvantage of this execution resides in the fact that it is necessary to take out the two ends of the loop to put or remove a key with, in addition, a locking mechanism filling with impurities contained in the pockets and often causing seizure when opening the keychain.

Dans une autre exécution présentement connue de porte-clés, on utilise une boucle qui est simplement munie d'un fermoir, dont l'inconvénient majeur réside au niveau de la construction qui est faite pour une durée relativement courte. In another presently known embodiment of a keychain, a buckle is used which is simply provided with a clasp, the major drawback of which lies in the construction which is made for a relatively short duration.

Le porte-clés objet de la présente invention remédie totalement aux défauts mentionnés ci-dessus et présente, en plus, I'avantage d'avoir un mecanisme qui pivote à l'une des extrémités de la boucle pour la mise en place d'une ou plusieurs clés, ce qui permet une plus grande sécurité de fonctionnement et, en plus, permet d'avoir un blocage construit de façon à donner au porte-clés, sur le plan esthétique, un aspect et une forme attrayants. The key ring object of the present invention completely remedies the above mentioned defects and has, in addition, the advantage of having a mechanism which pivots at one end of the loop for the establishment of a or more keys, which allows greater operational safety and, in addition, allows a blocking constructed so as to give the key ring, aesthetically, an attractive appearance and shape.

Le porte-clés selon l'invention est caractérisé en ce que la boucle est munie, à ses deux extrémités, d'une partie de révolution encastrée dans au moins un chambrage verrouillé, en position de fermeture de la boucle, au moyen d'un mobile coulissant librement dans une rainure. The keychain according to the invention is characterized in that the loop is provided, at its two ends, with a part of revolution embedded in at least one locked recess, in the closed position of the loop, by means of a mobile sliding freely in a groove.

Le dessin annexé représente, à titre d'exemple non limitatif, des formes d'exécution du porte-clés objet de l'invention; dans ce dessin: la fig. 1 montre une vue agrandie de face du porte-clés; la fig. 2 montre une vue agrandie de profil conforme à la fig. 1; la fig. 3 montre une variante d'exécution partielle du dispositif d'usinage; la fig. 4 montre une variante d'exécution de face partielle du mobile de blocage; la fig. 5 montre une vue de profil partielle conforme à la fig. 4; la fig. 6 montre une autre variante d'exécution de face partielle du mobile de blocage; la fig. 7 montre une vue de profil partielle conforme à la fig. 6. The appended drawing represents, by way of nonlimiting example, embodiments of the key-ring object of the invention; in this drawing: fig. 1 shows an enlarged front view of the key holder; fig. 2 shows an enlarged profile view in accordance with FIG. 1; fig. 3 shows a variant embodiment of the machining device; fig. 4 shows an alternative embodiment of the partial face of the locking mobile; fig. 5 shows a partial profile view in accordance with FIG. 4; fig. 6 shows another alternative embodiment of the partial face of the locking mobile; fig. 7 shows a partial profile view in accordance with FIG. 6.

On va maintenant décrire, en regard des fig. 1 et 2, le porte-clés objet de l'invention, qui comprend: un profilé 1 muni d'une boucle 2, dont l'une des extrémités 3 est pourvue d'une partie cylindrique 5 terminée par un épaulement 6 venant s'encastrer dans un chambrage 7 qui est fraisé dans le profilé 1; l'autre extrémité 8 est identique quant à la forme et à la fonction décrites pour l'extrémité 3 de la boucle 2. We will now describe, with reference to FIGS. 1 and 2, the key ring object of the invention, which comprises: a profile 1 provided with a loop 2, one of the ends 3 of which is provided with a cylindrical part 5 terminated by a shoulder 6 coming from embed in a recess 7 which is countersunk in the profile 1; the other end 8 is identical as regards the shape and the function described for the end 3 of the loop 2.

Le profilé 1 est encore pourvu d'un mobile 10, qui coulisse transversalement par des moyens connus et par conséquent non décrits, dans une rainure 12 du profilé 1. La surface inférieure 13 de la rainure 12 présente des trous 14, 15, 16 servant au positionnement de la bille 17, pour le maintien du mobile 10 dans une position déterminée. The profile 1 is also provided with a mobile 10, which slides transversely by known means and therefore not described, in a groove 12 of the profile 1. The lower surface 13 of the groove 12 has holes 14, 15, 16 serving in positioning the ball 17, for maintaining the mobile 10 in a determined position.

Le principe de fonctionnement est le suivant: lorsqu'on veut mettre une clé dans la boucle 2, on procède au glissement du mobile 10 dans la direction de la flèche A (fig. 1), ce qui permet le déblocage du chambrage 7, respectivement l'ouverture de la boucle 2 qui pivote, en direction de la tléche (fig. 2), sur l'extrémité 8, le mobile 10 étant ensuite replacé de façon que la bille 17 vienne s'encastrer dans le trou 15 fermant le chambrage 7. The operating principle is as follows: when one wants to put a key in the loop 2, one proceeds to the sliding of the mobile 10 in the direction of the arrow A (fig. 1), which allows the recess of the recess 7, respectively the opening of the loop 2 which pivots, in the direction of the tlèche (fig. 2), on the end 8, the mobile 10 then being replaced so that the ball 17 comes to be embedded in the hole 15 closing the recess 7.

Comme le montre explicitement la fig. 1, le mobile 10 peut également glisser de façon à libérer l'extrémité 8 et à faire pivoter la boucle 2 sut l'extrémité 3. Dans une variante d'exécution se rapportant à la fig. 3, une partie conique 20 vient s'encastrer dans un chambrage 21 qui est verrouillé au moyen d'un mobile 22 coulissant dans une rainure 23. As shown in fig. 1, the mobile 10 can also slide so as to release the end 8 and to rotate the loop 2 on the end 3. In an alternative embodiment referring to FIG. 3, a conical part 20 is fitted into a recess 21 which is locked by means of a mobile 22 sliding in a groove 23.

Dans une autre variante d'execution (fig. 4 et 5), un mobile 25 coulisse sur une queue d'aigle 26 qui est rapportée directement au niveau d'une partie conique 27 se logeant dans un chambrage 28. In another alternative embodiment (FIGS. 4 and 5), a mobile 25 slides on an eagle tail 26 which is brought directly to the level of a conical part 27 being housed in a recess 28.

Les fig. 6 et 7 montrent une autre variante d'exécution qui comprend un mobile 30 qui coulisse dans une rainure 31 usinée dans l'extrémité 32 d'une boucle et sur le devant de la paroi de guidage 33, permettant ainsi due faire, d'une part, le blocage de la boucle et, d'autre part, le coulissage du mobile 30. Figs. 6 and 7 show another alternative embodiment which comprises a mobile 30 which slides in a groove 31 machined in the end 32 of a loop and on the front of the guide wall 33, thus allowing due on the one hand, the blocking of the loop and, on the other hand, the sliding of the mobile 30.
