FERMOIR DE BRACELET A BOUCLE GLISSANTEBRACELET CLOSURE WITH SLIDING LOOP
Domaine techniqueTechnical area
[0001] La présente invention concerne un fermoir à boucle glissante destiné à équiper un bracelet de type fermé utilisable aussi bien en horlogerie qu'en bijouterie mais aussi, plus généralement, en tant que tout type de collier destiné à être placé autour d'un corps, de manière amovible.The present invention relates to a sliding buckle clasp for fitting a closed type of strap used both in watchmaking and jewelry but also, more generally, as any type of collar to be placed around a body, removably.
Etat de la techniqueState of the art
[0002] Les bracelets sont soit de type ouvert, lorsque leurs deux brins peuvent être complètement séparés, soit de type fermé, lorsque les brins restent solidaires et sont reliés l'un à l'autre par une boucle permettant d'augmenter leur diamètre afin de pouvoir y passer la main.The bracelets are either open type, when their two strands can be completely separated or closed type, when the strands remain attached and are connected to one another by a loop to increase their diameter so to be able to pass the hand.
[0003] Les bracelets de ce deuxième type, auxquels l'invention s'applique, utilisent le plus souvent une boucle, dite déployante, qui comporte généralement un fermoir à deux lames articulées en papillon. En position fermée, les lames sont maintenues repliées l'une sur l'autre. L'actionnement du fermoir autorise leur déploiement et donc l'élargissement du bracelet.The bracelets of this second type, to which the invention is applicable, most often use a so-called folding buckle, which generally comprises a clasp with two blades articulated butterfly. In the closed position, the blades are kept folded over one another. The operation of the clasp allows their deployment and thus the enlargement of the bracelet.
[0004] Certaines réalisations de bracelets de type fermé, moins fréquentes, utilisent une boucle, dite glissante, comme proposé dans le documentSome embodiments of closed type bracelets, less frequent use a so-called sliding loop, as proposed in the document
GB 680 368. La boucle comporte alors une lame flexible montée fixe dans l'un des deux brins par sa première extrémité, et coulissante dans l'autre brin par sa deuxième extrémité. Une telle structure, quelque peu rudimentaire, évite, certes, la complication d'une boucle déployante, mais elle ne garantit pas que les deux brins resteront réunis en cas d'importante sollicitation du bracelet dont une ouverture intempestive est donc possible.GB 680 368. The loop then comprises a flexible blade fixedly mounted in one of the two strands by its first end, and sliding in the other strand by its second end. Such a structure, somewhat rudimentary, avoids, admittedly, the complication of a folding clasp, but it does not guarantee that the two strands will remain together in case of significant stress on the bracelet which untimely opening is possible.
[0005] Le document GB1 261 027 propose un bracelet à boucle glissante dont la lame flexible ne coulisse également que dans un brin du bracelet par l'une de ses extrémités. Toutefois, ce dispositif est exempt de l'inconvénient susmentionné du fait que cette extrémité est munie de deux doigts formant un Y, ces doigts empêchant que la lame sorte totalement du brin dans lequel elle est logée.GB1 261 027 proposes a sliding loop bracelet whose flexible blade also slides in a strand of the bracelet by one of its ends. However, this device is free from the aforementioned disadvantage of the fact that this end is provided with two fingers forming a Y, these fingers preventing the blade completely out of the strand in which it is housed.
[0006] Cependant, la lame ne coulissant que dans un brin, il est difficilement envisageable que les conditions de glissement à l'intérieur du brin puissent se faire dans de bonnes conditions sur une longueur importante, d'autant que la flexion que subit la lame entraîne des frottements importants entre elle et le bracelet. De plus, le bracelet étant nécessairement creux et rigide pour permettre le coulissement de la lame, il est peu confortable pour le porteur. De fait, un tel dispositif ne peut s'adapter à des bracelets souples, en cuir, en caoutchouc ou même métallique à maillons articulés.However, the blade sliding only in a strand, it is difficult to envisage that the sliding conditions inside the strand can be done in good conditions over a significant length, especially as the bending experienced by the blade causes significant friction between her and the bracelet. In addition, the bracelet is necessarily hollow and rigid to allow the sliding of the blade, it is uncomfortable for the wearer. In fact, such a device can not adapt to soft bracelets, leather, rubber or even metal articulated links.
[0007] La présente invention a donc pour but de proposer une version améliorée d'un fermoir de bracelet à boucle glissante, exempt des inconvénients susmentionnés et s'adaptant à tout type de bracelet. Divulgation de l'inventionThe present invention therefore aims to provide an improved version of a sliding loop clasp, free of the aforementioned drawbacks and adapting to any type of bracelet.

[0011] En variante, la lame est réalisée en deux parties conformées de manière à s'emboîter télescopiquement l'une dans l'autre, chacune étant solidaire de l'un des éléments de fermeture mais capable de coulisser dans l'autre.Alternatively, the blade is made in two parts shaped so as to telescopically engage one into the other, each being secured to one of the closure elements but capable of sliding in the other.
[0012] Dans un autre mode de réalisation, la lame est munie d'une première coulisse. Les éléments de fermeture comportent chacun un patin coopérant avec cette première coulisse pour permettre le déplacement relatif des éléments et de la lame.In another embodiment, the blade is provided with a first slide. The closing elements each comprise a shoe cooperating with this first slide to allow relative movement of the elements and the blade.
[0013] Dans une autre variante particulièrement avantageuse, la lame est munie d'une première coulisse, le fermoir comporte un premier et un deuxième coulisseaux se déplaçant dans cette première coulisse de part et d'autre de l'organe pour limiter la course de la lame en position fermée. Les premier et deuxième coulisseaux forment chacun une deuxième coulisse. Les éléments de fermeture comportent chacun un patin coopérant respectivement avec la deuxième coulisse des premier et deuxième coulisseaux, pour permettre le déplacement relatif des éléments et de la lame.In another particularly advantageous variant, the blade is provided with a first slide, the clasp comprises a first and a second slide moving in this first slide on either side of the member to limit the stroke of the blade in the closed position. The first and second slides each form a second slide. The closing elements each comprise a pad cooperating respectively with the second slide of the first and second slides, to allow relative movement of the elements and the blade.
[0014] L'invention concerne aussi un bracelet souple ou à maillons articulés doté d'un fermoir tel que défini ci-dessus.The invention also relates to a flexible bracelet or articulated links with a clasp as defined above.

Its front portion 18a has a thin rectangular channel 22 in which can move freely a blade 24, flexible or rigid, preferably made of steel, carbon, Kevlar, plastic, gold or platinum and described later in detail. The rear portion 18b constitutes a housing in which a end of the bracelet can be fixed by screw, by bar or by any other means available to the skilled person.
[0021] L'élément 20 constitue la moitié passive du fermoir. Sa partie avant 20a possède un mince canal 26, identique au canal 22, dans lequel peut également se mouvoir librement la lame 24. La partie arrière 20b constitue un logement dans lequel l'autre extrémité du bracelet peut être fixée de la même manière que mentionnée ci-dessus.The element 20 constitutes the passive half of the clasp. Its front portion 20a has a thin channel 26, identical to the channel 22, in which the blade 24 can also move freely. The rear portion 20b constitutes a housing in which the other end of the bracelet can be fixed in the same manner as mentioned. above.
[0022] La lame 24 pénètre ensuite, par ses extrémités, dans les deux brins 10 et 12 du bracelet qui doivent donc être aménagés pour la recevoir et la laisser coulisser librement.The blade 24 then enters, by its ends, in the two strands 10 and 12 of the bracelet which must be arranged to receive it and let it slide freely.
[0023] Pour permettre l'accouplement des deux éléments du fermoir, l'élément actif 18 reçoit, dans sa partie avant 18a, deux poussoirs 28 alignés face à face selon un axe transversal XX perpendiculaire à l'axe longitudinal YY du bracelet et logés dans des ouvertures ménagées dans les faces latérales du corps 18. Un joint torique 30 sert à éviter l'accumulation de salissures dans l'élément 18.To allow the coupling of the two elements of the clasp, the active element 18 receives, in its front portion 18a, two pushers 28 aligned face to face along a transverse axis XX perpendicular to the longitudinal axis YY of the bracelet and housed in openings in the side faces of the body 18. An O-ring 30 serves to prevent the accumulation of dirt in the element 18.
[0024] Comme le montre aussi la figure 3, les poussoirs 28 servent à actionner chacun une griffe 32 formée d'un corps semi-tubulaire 34 capable de se déplacer selon l'axe XX dans un logement cylindrique 36 d'axe parallèle à YY. Le poussoir 28 agit sur le milieu de la face externe du corps 34.As also shown in Figure 3, the pushers 28 serve to actuate each a claw 32 formed of a semi-tubular body 34 capable of moving along the axis XX in a cylindrical housing 36 of axis parallel to YY . The pusher 28 acts on the middle of the external face of the body 34.
Celui-ci sert de berceau à une lamelle ressort circulaire 38 ouverte du côté opposé au poussoir et se prolonge, hors du logement 36, par un crochet 40 sortant de la face avant de l'élément 18.This serves as a cradle for a circular spring blade 38 open on the opposite side to the pusher and extends, out of the housing 36, by a hook 40 coming out of the front face of the element 18.
[0025] De son côté, l'élément passif 20 du fermoir possède, dans sa face avant, deux logements 42 conformés et dimensionnés pour recevoir les crochets 40 de l'élément actif 18.For its part, the passive element 20 of the clasp has, in its front face, two housings 42 shaped and dimensioned to receive the hooks 40 of the active element 18.
[0026] Afin de faciliter l'accouplement des deux moitiés du fermoir, l'élément 18 possède, sur sa face avant, deux goupilles de guidage 44 prenant place dans des logements ménagés dans le face avant de l'élément 20. [0027] Ainsi, pour accoupler les deux moitiés du fermoir, il suffit de les amener face à face, en s'aidant des goupilles de guidage 44. L'actionnement simultané des deux poussoirs 28 permet alors de comprimer les lames ressorts 38 contre la paroi des logements 36 et de déplacer ainsi les griffes 32 vers l'intérieur, de manière à laisser leurs crochets 40 pénétrer dans les logements 42. Le relâchement des poussoirs 28 fait revenir les ressorts 38 à leur position de repos en déplaçant les griffes 32 vers l'extérieur, de sorte que les crochets 40 s'arriment à l'élément 20 dans les logements 42. Le bracelet est ainsi fermé et verrouillé.To facilitate the coupling of the two halves of the clasp, the element 18 has, on its front face, two guide pins 44 taking place in housings formed in the front face of the element 20. [0027] Thus, to couple the two halves of the clasp, simply bring them face to face, with the help of the guide pins 44. The actuation simultaneous two pushers 28 then allows to compress the leaf springs 38 against the wall of the housing 36 and thus move the claws 32 inwardly, so as to let their hooks 40 enter the housing 42. The release of the pushers 28 is return the springs 38 to their rest position by moving the claws 32 outwardly, so that the hooks 40 are attached to the element 20 in the housing 42. The bracelet is thus closed and locked.
[0028] A l'inverse, pour ouvrir le bracelet, il suffit d'enfoncer à nouveau les deux poussoirs 28 qui, en comprimant les ressorts 38, permettent de dégager les crochets 40 de leurs logements 42. Les deux moitiés du fermoir peuvent alors être séparées.Conversely, to open the bracelet, simply push the two pushers 28 which, by compressing the springs 38, allow to release the hooks 40 of their housing 42. The two halves of the clasp can then to be separated.
[0029] On se référera maintenant à la figure 4 qui représente une première forme de réalisation possible du fermoir selon l'invention, les brins du bracelet n'étant pas montrés. Sur cette figure, comme pour les figures suivantes, on retrouvera les éléments déjà décrits, affectés des mêmes numéros de référence.Referring now to Figure 4 which shows a first possible embodiment of the clasp according to the invention, the strands of the bracelet are not shown. In this figure, as for the following figures, we find the elements already described, assigned the same reference numbers.
[0030] La lame 24, qui est maintenant montrée sur toute sa longueur, est plate et se termine, à ses deux extrémités, par une portion recourbée 46 qui vient en butée contre l'entrée du canal 22 ou 26 respectivement de l'élément 18 ou 20, et ne peut y pénétrer, limitant ainsi la course des deux moitiés du fermoir (c'est-à-dire l'ouverture du bracelet) et évitant que celles-ci se désolidarisent de la lame. Celle-ci possède, en son milieu, un rivet 48 (aussi visible sur les figures 1 et 2) qui, comme les portions d'extrémité recourbées 46, ne peut pénétrer dans les canaux 22 et 26, assurant ainsi la même course à chaque moitié du fermoir.The blade 24, which is now shown over its entire length, is flat and ends at both ends by a curved portion 46 which abuts against the inlet of the channel 22 or 26 respectively of the element. 18 or 20, and can not enter, limiting the stroke of the two halves of the clasp (that is to say the opening of the bracelet) and preventing them from disengaging the blade. It has, in the middle, a rivet 48 (also visible in Figures 1 and 2) which, like the curved end portions 46, can not enter the channels 22 and 26, thus ensuring the same race at each half of the clasp.
[0031] Les portions recourbées 46 et le rivet 48 ne sont que des exemples de moyens pour limiter la course des deux moitiés du fermoir par rapport à la lame 24. Tout autre système ayant le même effet est, bien entendu, utilisable dans le cadre de l'invention. [0032] La lame 24 montrée sur les figures précédemment décrites est plate, mais elle pourrait aussi, comme le montre la figure 5, être profilée, en longueur et en largeur, de toute manière qui la rendrait plus ou moins rigide et/ou plus ou moins allégée, notamment au moyen de découpes 50 et de nervures latérales 52.The curved portions 46 and the rivet 48 are only examples of ways to limit the stroke of the two halves of the clasp relative to the blade 24. Any other system having the same effect is, of course, usable in the context of the invention. The blade 24 shown in the previously described figures is flat, but it could also, as shown in Figure 5, be profiled, in length and width, in any way that would make it more or less rigid and / or more or less lightened, in particular by means of cutouts 50 and lateral ribs 52.
[0033] Enfin, dans le fermoir de la figure 6, la lame 24 est réalisée en deux parties 24a et 24b conformées de manière à s'emboîter télescopiquement l'une dans l'autre. Dans ce cas, la demi-lame 24a est rendue solidaire de l'élément 18 mais peut coulisser dans l'élément 20 pour occuper, en fin de course, lorsque le bracelet est complètement fermé, la position représentée en pointillés. De manière symétrique, la demi-lame 24b est rendue solidaire de l'élément 20 mais peut coulisser dans l'élément 18 pour occuper, en fin de course, la position représentée en pointillés.Finally, in the clasp of Figure 6, the blade 24 is formed in two parts 24a and 24b shaped so as to telescopically fit one into the other. In this case, the half-blade 24a is made integral with the element 18 but can slide in the element 20 to occupy, at the end of the race, when the bracelet is completely closed, the position shown in dotted lines. In a symmetrical manner, the half-blade 24b is made integral with the element 20 but can slide in the element 18 to occupy, at the end of the race, the position shown in dashed lines.
[0034] Un mode de réalisation présenté aux figures 7 à 10 reprend le principe d'une lame formée d'éléments télescopiques. Ce fermoir à boucle glissante présente, non seulement, les avantages des modes de réalisation décrits ci-dessus mais permet, en outre, de manière très avantageuse, de s'adapter à tout type de bracelets souples, en cuir, en caoutchouc ou même métallique à maillons articulés. En effet, comme on le comprendra mieux ci-après, il n'est pas nécessaire que le bracelet soit aménagé particulièrement pour recevoir la lame flexible. [0035] Ainsi, de manière plus détaillée, la lame du fermoir selon ce mode de réalisation particulier présente la forme d'une plaque centrale 60 dont les bords longitudinaux, c'est-à-dire parallèles à l'axe Y-Y, forment une première coulisse 62.An embodiment shown in Figures 7 to 10 shows the principle of a blade formed of telescopic elements. This sliding buckle clasp has not only the advantages of the embodiments described above but also makes it very advantageous to adapt to any type of flexible bracelets, leather, rubber or even metal with articulated links. Indeed, as will be better understood below, it is not necessary that the bracelet is arranged particularly to receive the flexible blade. Thus, in more detail, the blade clasp according to this particular embodiment has the shape of a central plate 60 whose longitudinal edges, that is to say parallel to the axis YY, form a first slide 62.
[0036] Dans cette version également, le dispositif est muni d'organes pour limiter la course de la lame, permettant de définir, soit la position fermée, soit la position ouverte du fermoir. Un premier rivet 64 pour limiter la course de la lame en position fermée est disposé dans la portion centrale de la plaque 62, avantageusement en son milieu en référence à la longueur de celle-ci. Un deuxième rivet 65 pour limiter la course de la lame en position ouverte, est disposé à une première extrémité de la plaque. Ce rivet est visible sur les figures 8 à 10. [0037] Un premier coulisseau 66 est formé d'un élément profilé semblable à la lame 24 telle que décrite ci-dessus à propos du mode de réalisation de la figure 5. Ce coulisseau 66 présente la forme d'un cadre dont les bords longitudinaux 66a sont adaptés et dimensionnés pour coulisser sans jeu dans la première coulisse 62.In this version also, the device is provided with members to limit the stroke of the blade, to define either the closed position or the open position of the clasp. A first rivet 64 to limit the stroke of the blade in the closed position is disposed in the central portion of the plate 62, preferably in its middle with reference to the length thereof. A second rivet 65 to limit the stroke of the blade in the open position, is disposed at a first end of the plate. This rivet is visible in Figures 8 to 10. A first slider 66 is formed of a profiled element similar to the blade 24 as described above with respect to the embodiment of FIG. 5. This slider 66 has the shape of a frame whose longitudinal edges 66a are adapted and dimensioned to slide without play in the first slide 62.
[0038] La hauteur du premier rivet 64 est ajustée de manière à ce qu'il coopère avec la paroi externe du bord transversal 66b du cadre, située du côté du rivet 64. Cette paroi est munie d'un logement 68de forme semi- circulaire, capable de recevoir la moitié environ du rivet 64. [0039] Le rivet 65 est situé à l'intérieur du cadre 66. En pratique, le rivet est serti après que le cadre ait été positionné correctement. Sa hauteur est également ajustée de manière à ce qu'il coopère avec la paroi interne du bord transversal 66b du cadre 66.The height of the first rivet 64 is adjusted so that it cooperates with the outer wall of the transverse edge 66b of the frame, located on the side of the rivet 64. This wall is provided with a housing 68 of semi-circular shape , capable of receiving about half of the rivet 64. The rivet 65 is located inside the frame 66. In practice, the rivet is crimped after the frame has been positioned correctly. Its height is also adjusted so that it cooperates with the inner wall of the transverse edge 66b of the frame 66.
[0040] En outre, les bords longitudinaux 66a du cadre sont dimensionnés pour former une deuxième coulisse.In addition, the longitudinal edges 66a of the frame are sized to form a second slide.
[0041] Enfin, comme ci-dessus, le fermoir comprend un premier élément 18 et un deuxième élément 20 constituant le fermoir proprement dit. L'élément 18 est de forme globale parallélépipédique et comporte des poussoirs 28 permettant d'actionner des crochets de verrouillage 40. De plus, à sa base, l'élément 18 est doté d'un patin 70, mieux visible sur les figures 9 et 10, dimensionné et conformé pour coulisser sans jeu dans la deuxième coulisse. Le patin 70 est doté, sous lui, d'une goupille 72, visible sur la figure 10, dimensionnée pour coopérer avec la paroi interne du côté transversal 66b du cadre, sans gêner le coulissement de patin.Finally, as above, the clasp comprises a first element 18 and a second element 20 constituting the clasp itself. The element 18 is of parallelepipedal overall shape and comprises pushers 28 for actuating locking hooks 40. In addition, at its base, the element 18 is provided with a pad 70, better visible in FIGS. 10, dimensioned and shaped to slide without play in the second slide. The pad 70 is provided beneath it with a pin 72, visible in FIG. 10, dimensioned to cooperate with the internal wall of the transverse side 66b of the frame, without hindering the sliding of the pad.
[0042] La hauteur du rivet 64 est ajustée de manière à ce qu'il coopère également avec l'élément 18 pour limiter sa course dans la position fermée. Ainsi, le patin 70 présente un logement situé du côté du rivet 64, dans lequel ce dernier prend place et vient buter, lorsque le fermoir est en position fermée. [0043] Les goupilles 65 et 72 étant toutes deux destinées à coopérer avec la paroi 66b, elles sont donc situées dans un même plan X-Y. Toutefois, elles sont décalées selon l'axe transversal X-X pour qu'elles ne puissent se heurter lors de mouvements relatifs du coulisseau 66 et de l'élément 18.The height of the rivet 64 is adjusted so that it also cooperates with the element 18 to limit its stroke in the closed position. Thus, the shoe 70 has a housing located on the side of the rivet 64, in which the latter takes place and abuts, when the clasp is in the closed position. The pins 65 and 72 are both intended to cooperate with the wall 66b, they are therefore located in the same plane XY. However, they are offset along the transverse axis XX so that they can not collide during relative movements of the slider 66 and the element 18.
[0044] Symétriquement par rapport au milieu de la plaque 60 et au rivet 64, le fermoir comporte un autre coulisseau 80 semblable à celui décrit ci- dessus et portant la référence 66. L'élément 20 possédant des logements 42 pour recevoir les crochets 40 de l'élément 18, coulisse dans ce coulisseau 80 grâce à un patin 82 dont il est doté, semblable au patin 70. Le rivet 64 sert également de limitateur de course en position fermée et est susceptible de prendre place dans un logement dont est muni la paroi externe du bord transversal 66b du cadre formant le coulisseau 80. [0045] Les éléments disposés symétriquement sont également munis d'organes pour limiter la course de la lame, semblables à ceux référencés ci-dessus.Symmetrically relative to the middle of the plate 60 and the rivet 64, the clasp comprises another slide 80 similar to that described above and bearing the reference 66. The element 20 having housing 42 to receive the hooks 40 of the element 18, slides in this slider 80 through a shoe 82 which it is equipped, similar to the shoe 70. The rivet 64 also serves as a stroke limiter in the closed position and is likely to take place in a housing which is provided with the outer wall of the transverse edge 66b of the frame forming the slide 80. The elements arranged symmetrically are also provided with members to limit the stroke of the blade, similar to those referenced above.
[0046] Ainsi, en position fermée, les éléments 18 et 20 sont appuyés sur le rivet 64 et sont au contact l'un de l'autre, les crochets 40 coopérant avec les logements 42. Les parois externes des bords transversaux des coulisseaux 66 et 80 sont aussi en appui sur le rivet 64, la goupille 72 des patins 70 et 82 des éléments 18 et 20 s'appuyant sur les parois internes des bords transversaux des coulisseaux 66 et 80 .Thus, in the closed position, the elements 18 and 20 are supported on the rivet 64 and are in contact with one another, the hooks 40 cooperating with the housing 42. The outer walls of the transverse edges of the slides 66 and 80 are also resting on the rivet 64, the pin 72 of the pads 70 and 82 of the elements 18 and 20 resting on the inner walls of the transverse edges of the slides 66 and 80.
[0047] En position ouverte, les coulisseaux 66 et 80 sont appuyés par la paroi interne de leur bord transversal 66b et 80b sur la goupille 65. Les éléments 18 et 20 sont, eux, appuyés par la goupille 72 de leur patin sur les parois internes des bords transversaux respectivement opposés aux bords 66 et 80b.In the open position, the slides 66 and 80 are supported by the inner wall of their transverse edge 66b and 80b on the pin 65. The elements 18 and 20 are, themselves, supported by the pin 72 of their pad on the walls internal transverse edges respectively opposite the edges 66 and 80b.
[0048] Ainsi qu'illustré sur la figure 7, le fermoir qui vient d'être décrit peut recevoir un bracelet souple, en cuir ou en caoutchouc, par exemple. Un premier brin 10 du bracelet est fixé, par une première de ses extrémités, à l'élément 18 au moyen de vis 84 ou par une barrette. [0049] L'élément 20 est muni, pour recevoir et fixer le deuxième brin du bracelet, d'une boucle 86 définissant un cadre et montée pivotante sur l'élément 20 par deux vis 88. La boucle est dimensionnée pour laisser passer le bracelet à plat à l'intérieur du cadre. [0050] Ce cadre est doté d'un clou 89 destiné à se loger dans l'un des trous dont est normalement muni le bracelet, afin de permettre, de manière tout à fait classique, l'ajustement de sa longueur. La boucle 86 est agencée de manière à ce que, une fois que le clou 89 est positionné dans le trou adéquat du bracelet, une traction sur ce bracelet ne fasse pas pivoter la boucle.As illustrated in Figure 7, the clasp just described can receive a flexible bracelet, leather or rubber, for example. A first strand 10 of the bracelet is fixed, by a first of its ends, to the element 18 by means of screws 84 or by a bar. The element 20 is provided, for receiving and securing the second strand of the bracelet, a loop 86 defining a frame and pivotally mounted on the element 20 by two screws 88. The loop is sized to let the bracelet flat inside the frame. This frame is provided with a nail 89 intended to be housed in one of the holes which is normally provided with the bracelet, to allow, in a very conventional way, the adjustment of its length. The loop 86 is arranged so that, once the nail 89 is positioned in the appropriate hole of the bracelet, pulling on this bracelet does not rotate the loop.
[0051] La figure 9 représente le fermoir selon ce mode de réalisation adapté à un bracelet métallique à maillons articulés, dont les extrémités sont directement montées, de manière classique, sur les éléments 18 et 20. L'ensemble des éléments télescopiques du fermoir prenant place sous le bracelet, il n'est donc pas nécessaire que celui-ci soit particulièrement aménagé pour recevoir une partie glissante du fermoir.FIG. 9 represents the clasp according to this embodiment adapted to a metal bracelet with articulated links, the ends of which are directly mounted, in a conventional manner, on the elements 18 and 20. The set of telescopic elements of the clasp taking place under the bracelet, it is not necessary that it is particularly arranged to receive a slippery portion of the clasp.
[0052] Dans une variante simplifiée, l'homme du métier pourra mettre en œuvre un fermoir ne comportant, pour chacun des éléments 18 et 20, qu'un élément coulissant, c'est-à-dire que les coulisseaux 66 et 80 peuvent être supprimés. Dans ce cas, les patins 70 et 82 coulissent directement dans la coulisse 62 de la plaque 60. Celle-ci peut se terminer, à ses extrémités, par des rebords formant butées et limitant la course des éléments 18 et 20 en position ouverte.In a simplified variant, the skilled person can implement a clasp having, for each of the elements 18 and 20, a sliding element, that is to say that the slides 66 and 80 can to be deleted. In this case, the pads 70 and 82 slide directly into the slide 62 of the plate 60. This can be terminated at its ends by rims forming stops and limiting the stroke of the elements 18 and 20 in the open position.
[0053] Ainsi est proposé un fermoir de bracelet à boucle glissante qui ne souffre pas de la complexité des fermoirs à boucle déployante. Le fermoir selon l'invention est, à la fois, de construction simple et doté d'une boucle totalement invisible.Thus is proposed a sliding loop clasp that does not suffer from the complexity of clasps folding clasp. The clasp according to the invention is both of simple construction and has a totally invisible loop.
[0054] Les rivets 64 ou 48 servent de limitateurs de course en position fermée et permettent de répartir d'un côté et de l'autre par rapport aux éléments 18 et 20, la longueur des éléments coulissants. Il est donc possible que ces rivets ne soient pas exactement au centre du fermoir, si, toutefois, la répartition des éléments coulissants est satisfaisante en position fermée. The rivets 64 or 48 serve as limiters in the closed position and allow to distribute on one side and the other with respect to the elements 18 and 20, the length of the sliding elements. It is therefore possible that these rivets are not exactly in the center of the clasp, if, however, the distribution of the sliding elements is satisfactory in the closed position.
