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

Fermoir pour lien Clasp for link
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'oc¬ cuper deux positions, l'une, relevée, dans laquelle le fermoir est déverrouillé et l'autre, rabattue, dans laquelle le fermoir est verrouillé.The present invention relates to a link clasp provided with a locking device comprising a locking member articulated on the body of the clasp around a transverse axis, and which is capable of oc¬ cup two positions, one , raised, in which the clasp is unlocked and the other, folded, 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 per se. They are used for various applications, in particular for closing watch straps.
Dans ces fermoirs connus, l'organe de verrouil¬ lage 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 fer¬ moir. Une telle disposition n'exclut pas le risque d'un déverrouillage intempestif du fermoir. Le but de la présente invention est de fournir un moyen de maintien de l'organe articulé de verrouillage en position de verrouillage qui réduise les risques d'un déverrouillage intempestif.In these known clasps, the articulated locking device is most often constituted by a flap held in its folded locking position by means of an elastically deformable projection which the flap has and which hooks to the notch. another element of the closet. Such an arrangement does not exclude the risk of inadvertent unlocking of the clasp. The object of the present invention is to provide a means for holding the articulated locking member in the locking position which reduces the risks of inadvertent unlocking.
Ce but est atteint grâce aux moyens définis dans la revendication 1.This object is achieved by the means defined in claim 1.
Le dessin représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention.The drawing represents, by way of example, an embodiment of the subject of the invention.
La fig. 1 est une vue en perspective d'un fermoir pour bracelet de montre en position ouverte.Fig. 1 is a perspective view of a clasp for a watch strap in the open position.
La fig. 2 est une coupe de ce fermoir, à plus grande échelle, passant par l'axe d'articulation de l'or¬ gane de verrouillage, ce dernier étant en position rabattue, de verrouillage.Fig. 2 is a section of this clasp, on a larger scale, passing through the hinge axis of the locking or¬ gane, the latter being in the folded position, locking.
La fig. 3 est une coupe suivant la ligne III-III de la fig. 2.Fig. 3 is a section along line III-III of FIG. 2.
La fig. 4 est une coupe suivant la ligne IV-IV de la fig. 3. La fig. 5 est une vue en perspective d'un détail de ce fermoir, etFig. 4 is a section along the line IV-IV of FIG. 3. Fig. 5 is a perspective view of a detail of this clasp, and
La fig. 6 est une coupe analogue à celle de la fig. 2, l'organe de verrouillage du fermoir occu¬ pant sa position relevée, de déverrouillage.Fig. 6 is a section similar to that of FIG. 2, the locking member of the clasp occu¬ pant its raised position, unlocking.
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, respecti¬ vement 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 3ç_, 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'accro¬ cher, lorsque le fermoir est fermé, à une barrette trans¬ versale 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 form of stirrups 2 and 3 between the branches 2a and 2b, respecti¬ vely 3a ^ and 3b, of which the ends of the two strands are articulated 4 of a bracelet. The stirrup-shaped part 3 carries, fixed to its transverse part, designated by 3ç_, by welding for example, a longitudinal plate 5, the end of which is folded over at 5a. shaped like a gutter. This folded part 5a. forms a hook intended to hook, when the clasp is closed, to a transverse bar 6 disposed between the branches 2a. and 2b 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 5 _ empê¬ chant celui-ci de se dégager de la barrette transversale 6. Le volet de verrouillage 8 est articulé entre les branches 3ει 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 3ja 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 9ç_, de section droite de forme, c'est- à-dire non circulaire (figs. 4 et 5), cette partie 9£ étant elle-même suivie d'une partie terminale 9d s'engageant dans la seconde branche, 3b_, de la pièce 3.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 _ song preventing it from being released from the transverse bar 6. The locking flap 8 is articulated between the branches 3ει of the stirrup-shaped part 3 using a shaft 9 shown in perspective in FIG. 5. This shaft has a section 9a_ pierced with a blind hole 10, in which engages the end of a screw 11 which is screwed into the branch 3ja of the part 3. This screw 11 is itself blocked by a screw 12 screwed into the branch 3a .. The shaft 9 is extended by a section 9b_, of smaller section, followed by a part 9ç_, of straight section of shape, that is to say non-circular (figs. 4 and 5), this part 9 £ being itself followed by an end part 9d engaging in the second branch, 3b_, of part 3.
Cette seconde branche 3b présente, sur sa face interne faisant face à la partie 9£ de l'arbre 9, un frai¬ sage 13 dont la largeur correspond à celle de la partie 9ç_, dans lequel est engagée l'extrémité de cette partie 9£ sous l'effet de la poussée axiale exercée par la vis 11 sur l'arbre 9. Il résulte de l'engagement de la partie 9£ de l'arbre 9 dans le fraisage 13 que l'arbre 9 est empêché de tourner sur lui-même. 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 correspondante la forme de la par¬ tie 9£ 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.This second branch 3b has, on its internal face facing the part 9 £ of the shaft 9, a frai¬ sage 13 whose width corresponds to that of the part 9ç_, in which is engaged the end of this part 9 £ 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 £ of the shaft 9 in the milling 13 that the shaft 9 is prevented from turning on himself. The locking flap 8 has, along its rear edge, a transverse part 8a_, thicker (fig.4), forming a barrel pierced with a passage 14 crossed by the shaft 9. The length of this part 8a. is less than the distance separating the two branches 3a ^ and 3b_ from the stirrup-shaped part 3 so that the flap 8 can carry out, in addition to its rotary tilting movement around the shaft 9, a translational movement along of this tree. The end of the passage 14 located on the side of the branch 3b of the part 3 has, seen at the end, at 14a_, an entry of corresponding shape the shape of the part 9 £ of the shaft 9. Finally, a spring with flange 15, engaged on the end of the section 9a ^ of the shaft 9, bears on the one hand on the branch 3a_ of the part 3 and on the other hand on the end of the barrel 8a ^ 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 9£ 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. 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 9£ 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 flap occupies its folded position, in which it closes the hook 5a_, the inlet 14a_ of the passage 14 is oriented, relative to the shaft 9, in such a way that the part 9 £ can engage in the housing that constitutes the inlet 14a_, which blocks the flap 8 in the locked position, the shaft 9 not being able to rotate on itself. 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 £ from the shaft 9 of the housing 14a. 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 rabat¬ tue de verrouillage, sans risque d'un déverrouillage intempestif.Thanks to the arrangement described and shown, the flap 8 is perfectly locked in its rabat¬ kills locking position, without risk of inadvertent unlocking.
En variante, l'organe de verrouillage articulé pourrait présenter une forme différente de celle d'un volet,As a variant, the articulated locking member could have a shape different from that of a flap,
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. 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 un dis¬ positif tel que celui faisant l'objet du brevet suisse No 674.759 et du brevet européen correspondant No 0.373.184, tous deux aux noms des mêmes titulaires.Alternatively also, one could provide the case where the part 8a_ of the flap would have a projection or a shaped recess cooperating with a recess or a projection of corresponding shape presented by the internal face of the branch 3b of the stirrup-shaped part . It should be noted that in the example described and shown, the articulation shaft 9 of the flap 8 is held in place by a screw 11. However, one could foresee the case where this shaft is held in place on the d-shaped part 'caliper 3 by a device such as that which is the subject of Swiss patent No 674.759 and the corresponding European patent No 0.373.184, both in the names of the same owners.
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 to watch straps, as described and shown, but may be applied to any link, in particular to belts, belts, straps and the like.
