Abstract

PCT No. PCT/IB95/00194 Sec. 371 Date Sep. 17, 1996 Sec. 102(e) Date Sep. 17, 1996 PCT Filed Mar. 21, 1995 PCT Pub. No. WO95/25447 PCT Pub. Date Sep. 28, 1995A clasp with a locking flap (8) hingedly mounted between the arms (3a, 3b) of a yoke-shaped member (3) by means of a pin (9) extending through one portion (8a) of said flap (8). Said portion (8a) is shorter than the distance between the two arms (3a, 3b) so that the flap (8) is transversely translatable. The pin (9) has a straight portion (9c) partially inserted into a correspondingly shaped recess (13) in one arm (3b). The pin (9) is thus prevented from rotating about its own axis. The passage (14) in said portion (8a) of the flap which receives the pin (9) has an inlet (14a) shaped to fit said portion (9c) of the pin (9). A coil spring (15) on the pin (9) biases the flap (8) towards said portion (9c) of the pin (9). When the flap (8) is in the folded down or locking position, said portion (9c) of the pin (9) is inserted into the inlet (14a) of the passage (14), thereby locking the flap (8).

Description

La présente invention a pour objet un fermoir pour lien muni d'un dispositif de verrouillage comprenant un organe de verrouillage articulé sur le corps du fermoir autour d'un axe transversal, et qui est susceptible d'occuper deux positions, l'une, relevée, dans laquelle le fermoir est déverrouillé et l'autre, rabattue, dans laquelle le fermoir est verrouillé.The subject of the present invention is a clasp for link provided with a locking device comprising a locking member articulated on the body of the clasp around a transverse axis, and which is likely to occupy two positions, one raised, in which the the clasp is unlocked and the other, folded down, in which the clasp is locked.

Des fermoirs tels que ci-dessus sont connus en soi. Ils servent à diverses applications, en particulier à la fermeture des bracelets de montres.Clasps as above are known in oneself. They are used for various applications, in particular when closing watch straps.

Dans ces fermoirs connus, l'organe de verrouillage articulé est le plus souvent constitué par un volet maintenu dans sa position rabattue de verrouillage à l'aide d'une saillie déformable élastiquement que présente le volet et qui s'accroche à cran à un autre élément du fermoir. Une telle disposition n'exclut pas le risque d'un déverrouillage intempestif du fermoir. In these known clasps, the locking member articulated is most often made up of a flap held in its folded-down locking position using of an elastically deformable projection which the flap and which hooks notch to another element of the clasp. Such a provision does not exclude the risk of a inadvertent unlocking of the clasp.

On connaít également (voir brevet français No 54.478) des fermoirs pour bracelets munis d'un verrou coulissant qui peut occuper une position de travail dans laquelle il est poussé par un ressort de rappel, et dans laquelle il empêche l'ouverture du fermoir, et une position éclipsée, dans laquelle l'utilisateur l'amène à l'encontre de l'action dudit ressort de rappel, dans laquelle le fermoir est libéré dudit verrou et peut donc s'ouvrir.We also know (see French patent No. 54.478) clasps for bracelets fitted with a lock sliding which can occupy a working position in which it is pushed by a return spring, and in which prevents opening of the clasp, and a position eclipsed, in which the user brings it up against of the action of said return spring, in which the clasp is released from said lock and can therefore open.

Le but de la présente invention est d'améliorer les fermoirs connus tels que ceux décrits ci-dessus en munissant le fermoir d'un double dispositif de verrouillage, l'organe de verrouillage empêchant l'ouverture du fermoir étant lui-même verrouillé en position de travail de telle manière que, pour ouvrir le fermoir, il faille tout d'abord libérer le verrou puis amener celui-ci dans sa position dans laquelle il est inopérant, ce qui libère le fermoir. The aim of the present invention is to improve known clasps such as those described above by providing the clasp of a double locking device, the organ locking preventing opening of the clasp being itself locked in the working position in such a way that, to open the clasp, you must first release the lock and then bring it into its position in which it is inoperative, which releases the clasp.

Ce but est atteint grâce aux moyens définis dans la revendication 1.This goal is achieved thanks to the defined means in claim 1.

    • Le fermoir représenté est désigné, d'une façon générale, par 1. Il comprend deux pièces en forme d'étriers 2 et 3 entre les branches 2a et 2b, respectivement 3a et 3b,desquelles sont articulées les extrémités des deux brins 4 d'un bracelet. La pièce en forme d'étrier 3 porte, fixée à sa partie transversale, désignée par 3c, par soudage par exemple, une plaquette longitudinale 5 dont l'extrémité est repliée en 5a en forme de gouttière. Cette partie repliée 5a forme un crochet destiné à s'accrocher, lorsque le fermoir est fermé, à une barrette transversale 6 disposée entre les branches 2a et 2b de la pièce en forme d'étrier 2.The clasp shown is generally designated by 1. It comprises two pieces in the shape of stirrups 2 and 3 between the branches 2 a and 2 b , respectively 3 a and 3 b , of which the ends of the two are articulated strands 4 of a bracelet. The stirrup-shaped part 3 carries, fixed to its transverse part, designated by 3 c , by welding for example, a longitudinal plate 5, the end of which is folded back in 5 a in the form of a gutter. This folded part 5 has a hook intended to hang, when the clasp is closed, on a transverse bar 6 disposed between the branches 2 a and 2 b of the stirrup-shaped part 2.

    La pièce en forme d'étrier 3 porte, articulé sur elle en 7 (fig. 1), un volet de verrouillage 8 destiné à occuper une position soulevée, représentée à la fig. 1, dans laquelle le fermoir est déverrouillé, et une position rabattue dans laquelle il vient fermer le crochet 5a, empêchant celui-ci de se dégager de la barrette transversale 6. The stirrup-shaped part 3 carries, articulated on it at 7 (FIG. 1), a locking flap 8 intended to occupy a raised position, represented in FIG. 1, in which the clasp is unlocked, and a folded position in which it closes the hook 5 a , preventing the latter from being released from the transverse bar 6.

    Le volet de verrouillage 8 est articulé entre les branches 3a de la pièce en forme d'étrier 3 à l'aide d'un arbre 9 représenté en perspective à la fig. 5. Cet arbre présente un tronçon 9a percé d'un trou borgne 10, dans lequel s'engage l'extrémité d'une vis 11 se vissant dans la branche 3a de la pièce 3. Cette vis 11 est elle-même bloquée par une vis 12 vissée dans la branche 3a. L'arbre 9 se prolonge par un tronçon 9b, de plus petite section, suivie d'une partie 9c, de section droite de forme, c'est-à-dire non circulaire (figs. 4 et 5), cette partie 9c étant elle-même suivie d'une partie terminale 9d s'engageant dans la seconde branche, 3b, de la pièce 3.The locking flap 8 is articulated between the branches 3 a of the stirrup-shaped part 3 by means of a shaft 9 shown in perspective in FIG. 5. This shaft has a portion 9 pierced with a blind hole 10, into which the end of a screw 11 screwed into the branch 3a of the workpiece 3. This screw 11 is itself blocked by a screw 12 screwed into the branch 3 a . The shaft 9 is extended by a section 9 b , of smaller section, followed by a part 9 c , of cross section of shape, that is to say non-circular (figs. 4 and 5), this part 9 c being itself followed by a terminal part 9 d engaging in the second branch, 3 b , of part 3.

    Cette seconde branche 3b présente, sur sa face interne faisant face à la partie 9c de l'arbre 9, un fraisage 13 dont la largeur correspond à celle de la partie 9c, dans lequel est engagée l'extrémité de cette partie 9c sous l'effet de la poussée axiale exercée par la vis 11 sur l'arbre 9. Il résulte de l'engagement de la partie 9c de l'arbre 9 dans le fraisage 13 que l'arbre 9 est empêché de tourner sur lui-même. This second branch 3 b has, on its internal face facing part 9 c of the shaft 9, a milling 13 whose width corresponds to that of part 9 c , in which the end of this part 9 is engaged c under the effect of the axial thrust exerted by the screw 11 on the shaft 9. It results from the engagement of the part 9 c of the shaft 9 in the milling 13 that the shaft 9 is prevented from turning on himself.

    Le volet de verrouillage 8 présente, le long de son bord postérieur, une partie transversale 8a, plus épaisse (fig. 4), formant un canon percé d'un passage 14 traversé par l'arbre 9. La longueur de cette partie 8a est inférieure à la distance séparant les deux branches 3a et 3b de la pièce en forme d'étrier 3 de sorte que le volet 8 peut effectuer, outre son mouvement rotatif de basculement autour de l'arbre 9, un mouvement de translation le long de cet arbre. L'extrémité du passage 14 située du côté de la branche 3b de la pièce 3 présente, vue en bout, en 14a, une entrée de forme correspondant à la forme de la partie 9c de l'arbre 9. Enfin, un ressort à boudin 15, engagé sur l'extrémité du tronçon 9a de l'arbre 9, prend appui d'une part sur la branche 3a de la pièce 3 et d'autre part sur l'extrémité du canon 8a du volet 8. Ce ressort à boudin tend à déplacer le volet 8 vers la droite des figs. 2, 3 et 6.The locking flap 8 has, along its rear edge, a transverse part 8 a , thicker (fig. 4), forming a barrel pierced with a passage 14 crossed by the shaft 9. The length of this part 8 a is less than the distance separating the two branches 3 a and 3 b from the stirrup-shaped part 3 so that the flap 8 can perform, in addition to its rotary tilting movement around the shaft 9, a translational movement along this tree. The end of the passage 14 on the side of the branch 3b of the part 3 has, in end view, in 14a, a form entry corresponding to the shape of the portion 9 c of the shaft 9. Finally, a coil spring 15, engaged on the end of the section 9 a of the shaft 9, bears on the one hand on the branch 3 a of the part 3 and on the other hand on the end of the barrel 8 a of the flap 8. This coil spring tends to move the flap 8 to the right of Figs. 2, 3 and 6.

    Lorsque le volet occupe sa position rabattue, dans laquelle il ferme le crochet 5a, l'entrée 14a du passage 14 est orientée, par rapport à l'arbre 9, de telle manière que la partie 9c puisse s'engager dans le logement que constitue l'entrée 14a, ce qui bloque le volet 8 en position de verrouillage, l'arbre 9 ne pouvant pas tourner sur lui-même. When the flap occupies its folded position, in which it closes the hook 5 a , the inlet 14 a of the passage 14 is oriented, relative to the shaft 9, in such a way that the part 9 c can engage in the housing that constitutes the inlet 14 a , which blocks the flap 8 in the locked position, the shaft 9 not being able to rotate on itself.

    Lorsque l'utilisateur du fermoir agit sur une cheville 16 (fig. 1) que porte le volet 8, par exemple au moyen d'un ongle, il peut déplacer le volet le long de l'arbre 9, dans la direction de la flèche 17 de la fig. 6, à l'encontre de l'action du ressort de rappel 15, dégageant ainsi la partie 9c de l'arbre 9 du logement 14a. Le volet 8 peut alors être soulevé et amené dans la position représentée à la fig. 1, dans laquelle le fermoir est déverrouillé.When the user of the clasp acts on a pin 16 (fig. 1) which the flap 8 carries, for example by means of a nail, he can move the flap along the shaft 9, in the direction of the arrow 17 of fig. 6, against the action of the return spring 15, thus releasing the part 9 c of the shaft 9 from the housing 14 a . The flap 8 can then be lifted and brought into the position shown in FIG. 1, in which the clasp is unlocked.

    Grâce à la disposition décrite et représentée, le volet 8 est parfaitement bloqué dans sa position rabattue de verrouillage, sans risque d'un déverrouillage intempestif.Thanks to the arrangement described and shown, the flap 8 is perfectly locked in its folded position locking, without risk of unlocking untimely.

    En variante, l'organe de verrouillage articulé pourrait présenter une forme différente de celle d'un volet.Alternatively, the articulated locking member could have a different shape from that of a shutter.

    En variante également, on pourrait prévoir le cas où la partie 8a du volet présenterait une saillie ou une creusure de forme coopérant avec une creusure ou une saillie de forme correspondante présentée par la face interne de la branche 3b de la pièce en forme d'étrier. Also as a variant, could be provided if the portion 8a of the shutter present a protrusion or a recess of shape cooperating with a recess or a correspondingly shaped projection presented by the inner face of the branch 3b of the workpiece shaped 'stirrup.

    Il est à remarquer que dans l'exemple décrit et représenté l'arbre d'articulation 9 du volet 8 est maintenu en place par une vis 11. On pourrait cependant prévoir le cas où cet arbre serait maintenu en place sur la pièce en forme d'étrier 3 par tout autre dispositif connu.It should be noted that in the example described and shown the hinge shaft 9 of the flap 8 is held in place by a screw 11. One could however provide for the case where this tree is kept in place on the stirrup-shaped part 3 by any other device known.

    Enfin, l'invention n'est pas limitée à son application aux bracelets de montres, tel que décrit et représenté, mais pourra s'appliquer à tout lien, notamment aux ceintures, ceinturons, sangles et autres.Finally, the invention is not limited to its application watch straps, as described and shown, but may apply to any link, in particular to belts, belts, straps and others.
