FERMOIR POUR BRACELET DE PIECE D'HORLOGERIE Domaine technique  CLAMP FOR BRACELET OF HORLOGERIE PIECE Technical field
[0001] La présente invention concerne un fermoir, pour bracelet de pièce d'horlogerie du type comportant des premier et second brins comprenant des première et seconde extrémités libres correspondantes, le fermoir comportant une boucle destinée à être rendue solidaire de la première extrémité libre du bracelet et définissant un passage pour la seconde extrémité libre du bracelet, ainsi qu'un organe de verrouillage destiné à coopérer avec le second brin du bracelet pour assurer son verrouillage suivant la direction longitudinale du bracelet.  The present invention relates to a clasp for a timepiece bracelet of the type comprising first and second strands comprising corresponding first and second free ends, the clasp comprising a loop intended to be secured to the first free end of the bracelet and defining a passage for the second free end of the bracelet, and a locking member for cooperating with the second strand of the bracelet to ensure its locking in the longitudinal direction of the bracelet.
Etat de la technique State of the art
[0002] La plupart des fermoirs de bracelet, du type comportant des première et seconde extrémités libres, comprend une boucle assemblée à une première extrémité libre du bracelet au moyen d'une tige, éventuellement vissée, dont les deux extrémités sont engagées dans des trous adaptés de montants latéraux de la boucle. Un trou est ménagé dans la première extrémité libre du bracelet pour définir un passage pour un ardillon, monté pivotant sur la tige de fixation de la boucle. L'ardillon est ainsi destiné à coopérer avec un trou ménagé dans le second brin du bracelet pour en assurer le verrouillage suivant la direction longitudinale du bracelet.  Most bracelet clasps, of the type comprising first and second free ends, comprises a loop assembled at a first free end of the bracelet by means of a rod, optionally screwed, whose two ends are engaged in holes adapted from side jambs of the buckle. A hole is provided in the first free end of the bracelet to define a passage for a barb, pivotally mounted on the fastening rod of the buckle. The pin is thus intended to cooperate with a hole in the second strand of the bracelet to ensure locking in the longitudinal direction of the bracelet.
[0003] Toutefois, ces fermoirs présentent le principal inconvénient d'imposer l'utilisation d'outils pour effectuer un remplacement de la boucle, de la tige de fixation, ou encore de l'ardillon. However, these clasps have the main disadvantage of requiring the use of tools to perform a replacement of the loop, the fixing rod, or the barb.
[0004] En outre, la fabrication des bracelets correspondants est complexe lorsqu'il s'agit notamment de bracelets en cuirs ou en textiles, puisqu'il convient de replier une portion de l'une de leurs extrémités libres pour définir un logement pour la tige de fixation de la boucle, suivant la largeur du bracelet. En ce qui concerne le domaine plus particulier des bracelets haut de gamme, souvent en cuirs, cette portion repliée peut être inesthétique et nécessite la réalisation d'un bordage du bracelet pour en permettre la dissimulation. En outre, des coutures sont souvent réalisées sur ces bracelets pour garantir la solidité et la tenue dans le temps de la portion repliée. In addition, the manufacture of the corresponding bracelets is complex when it comes in particular bracelets leathers or textiles, since it is convenient to fold a portion of one of their free ends to define a housing for the Buckle fastening rod, depending on the width of the bracelet. Regarding the more particular field of high-end bracelets, often in leather, this folded portion can be unsightly and requires the realization of a pleating of the bracelet to allow concealment. In addition, seams are often made on these bracelets to ensure the strength and the holding over time of the folded portion.
[0005] Aussi, de manière plus précise, la présente invention concerne un fermoir du type mentionné plus haut dont la boucle comporte un premier montant transversal définissant au moins une paroi d'un logement, destiné à recevoir la première extrémité libre du bracelet et, comprenant au moins un organe de fixation destiné à coopérer avec cette dernière pour la rendre solidaire du premier montant transversal. La boucle comporte également des montants latéraux.  Also, more specifically, the present invention relates to a clasp of the type mentioned above, the loop comprises a first transverse amount defining at least one wall of a housing for receiving the first free end of the bracelet and, comprising at least one fixing member intended to cooperate with the latter to make it integral with the first transverse amount. The buckle also has lateral uprights.
[0006] Des structures de ce type sont connues dans le domaine des ceintures. Structures of this type are known in the field of belts.
Ainsi, à titre d'exemple, on notera que la demande de brevet WO 2010/012847 A1 décrit une ceinture dont le fermoir répond aux caractéristiques qui ont été énoncées ci-dessus.  Thus, by way of example, it will be noted that the patent application WO 2010/012847 A1 describes a belt whose clasp meets the characteristics which have been stated above.
[0007] Toutefois, les contraintes appliquées aux bandes utilisées dans le domaine des ceintures ne sont pas les mêmes que celles appliquées à des bracelets de montre, notamment du fait des différences de matériaux utilisés ainsi que des différences de dimensions entre une bande de ceinture et un bracelet de montre. However, the stresses applied to the bands used in the field of belts are not the same as those applied to watch straps, in particular because of the differences in materials used and the differences in size between a belt band and a watch bracelet.
Divulgation de l'invention Disclosure of the invention
[0008] Un but principal de la présente invention est de proposer un fermoir, pour bracelet de pièce d'horlogerie, interchangeable, de structure simple, susceptible d'être changé sans outil, et permettant par ailleurs de simplifier la fabrication des bracelets correspondants. A main object of the present invention is to provide a clasp for a timepiece bracelet, interchangeable, simple structure, can be changed without tools, and also to simplify the manufacture of the corresponding bracelets.
[0009] A cet effet, la présente invention concerne plus particulièrement un fermoir du type mentionné plus haut, caractérisé par le fait que le premier montant transversal est relié aux montants latéraux de manière à pouvoir pivoter en référence à ces derniers. For this purpose, the present invention relates more particularly to a clasp of the type mentioned above, characterized in that the first transverse amount is connected to the lateral uprights so as to pivot with reference to these.
[0010] Grâce à ces caractéristiques, le fermoir comprend un mode de fixation du bracelet différent, plus précisément simplifié, de celui décrit plus haut en relation avec l'état de la technique. En outre, un logement étant prévu dans le fermoir pour loger l'extrémité libre du bracelet, il n'est plus nécessaire de réaliser le logement complexe de la tige de fixation conventionnelle dans le bracelet, tel que décrit précédemment. [001 1] On notera en particulier que la seconde extrémité libre du bracelet peut plus facilement être insérée au travers de la boucle et le confort au porter est amélioré puisque le bracelet peut mieux suivre la courbure du poignet du porteur. With these features, the clasp includes a different mode of attachment of the bracelet, more specifically simplified, of that described above in connection with the state of the art. In addition, a housing being provided in the clasp to house the free end of the bracelet, it is no longer necessary to achieve the complex housing of the conventional fastening rod in the bracelet, as described above. [001 1] Note in particular that the second free end of the bracelet can be more easily inserted through the loop and the wearing comfort is improved since the bracelet can better follow the curvature of the wrist of the wearer.
[0012] Plus particulièrement, on peut prévoir que le premier montant transversal comporte au moins un doigt agencé pour coopérer avec des première et seconde butées ménagées sur au moins l'un des montants latéraux et définir une plage angulaire de pivotement du premier montant transversal en référence aux montants latéraux. More particularly, it can be provided that the first transverse upright comprises at least one finger arranged to cooperate with first and second stops arranged on at least one of the lateral uprights and define an angular range of pivoting of the first transverse upright. reference to lateral amounts.
[0013] Ainsi, la manipulation du bracelet par un utilisateur, lorsque ce dernier le met sur son poignet, est simplifiée puisque la boucle rencontre une butée lors de son mouvement de rotation, visant à la maintenir dans une orientation adaptée. Thus, the manipulation of the bracelet by a user, when the latter puts on his wrist, is simplified since the loop meets a stop during its rotational movement, to maintain it in a suitable orientation.
[0014] Suivant une variante de réalisation avantageuse, on peut prévoir en outre que le premier montant transversal comprend une barre principale, agencée suivant une direction transversale en référence à la direction longitudinale du bracelet et, se terminant à chaque extrémité par une portion pliée définissant un rebord, assemblé au montant latéral correspondant de manière à pouvoir pivoter.  According to an advantageous variant of embodiment, it can further be provided that the first transverse upright comprises a main bar, arranged in a transverse direction with reference to the longitudinal direction of the bracelet and ending at each end with a folded portion defining a rim, assembled to the corresponding lateral amount so as to pivot.
[0015] Dans ce cas, l'assemblage entre chacun des rebords et le montant latéral correspondant peut avantageusement être réalisé au moyen d'une vis vissée dans le rebord et libre de pivoter dans le montant latéral. In this case, the assembly between each of the flanges and the corresponding lateral amount can advantageously be achieved by means of a screw screwed into the flange and free to pivot in the lateral upright.
[0016] Selon un mode de réalisation préféré, l'organe de fixation comporte au moins un plot, préférablement au moins deux, présentant une première portion principale, sensiblement cylindrique, s'étendant suivant une direction sensiblement perpendiculaire depu is le prem ier mo nta nt transversal, destinée à coopérer avec un trou adapté de la première extrémité libre du bracelet. La première portion est surmontée d'une seconde portion, de dimensions transversales supérieures à celles de la première portion, pour assurer une retenue de la première extrémité libre du bracelet sur la première portion. [0017] De telles caractéristiques permettent non seulement de garantir une bonne fixation de la première extrémité libre du bracelet au fermoir, mais également de l'en retirer aisément. According to a preferred embodiment, the fixing member comprises at least one stud, preferably at least two, having a first main portion, substantially cylindrical, extending in a substantially perpendicular direction from the first mo nta transversely, intended to cooperate with a hole adapted to the first free end of the bracelet. The first portion is surmounted by a second portion of transverse dimensions greater than those of the first portion, to ensure retention of the first free end of the bracelet on the first portion. Such features not only make it possible to ensure that the first free end of the bracelet is securely fastened to the clasp, but also to remove it easily.
[0018] Par ailleurs, l'organe de verrouillage est préférablement porté par la boucle, à distance du premier montant transversal. En particulier, on peut prévoir qu'il est porté par un second montant transversal de la boucle.  Furthermore, the locking member is preferably carried by the loop, away from the first transverse amount. In particular, it can be expected that it is carried by a second transverse amount of the loop.
[0019] De plus, l'organe de verrouillage peut comprendre au moins un plot, présentant une première portion principale, sensiblement cylindrique, s'étendant suivant une direction sensiblement perpendiculaire depuis le second montant transversal, destinée à coopérer avec un trou adapté du second brin du bracelet, et surmontée d'une seconde portion, de dimensions transversales supérieures à celles de la première portion, pour assurer une retenue du second brin du bracelet sur la première portion.  In addition, the locking member may comprise at least one stud, having a first substantially cylindrical main portion extending in a substantially perpendicular direction from the second transverse post, intended to cooperate with a suitable hole of the second strand of the bracelet, and surmounted by a second portion of transverse dimensions greater than those of the first portion, to ensure retention of the second strand of the bracelet on the first portion.
[0020] De manière avantageuse, le ou les plots de l'organe de fixation, d'une part, et le plot de l'organe de verrouillage, d'autre part, s'étendent respectivement de part et d'autre d'un plan médian passant par les premier et second montants transversaux.  Advantageously, the one or more studs of the fastener, on the one hand, and the stud of the locking member, on the other hand, respectively extend on either side of a median plane passing through the first and second transverse uprights.
[0021] Le maintien du bracelet dans le fermoir est ainsi amélioré.  The maintenance of the bracelet in the clasp is thus improved.
[0022] Par ailleurs, l'invention concerne également un bracelet pour pièce d'horlogerie comportant une extrémité libre, destinée à coopérer avec un fermoir répondant aux caractéristiques ci-dessus et, présentant au moins un trou traversant suivant la direction de son épaisseur adapté pour coopérer avec l'organe de fixation du fermoir.  Furthermore, the invention also relates to a bracelet for a timepiece having a free end, intended to cooperate with a clasp satisfying the above characteristics and having at least one through hole in the direction of its adapted thickness. to cooperate with the fastener of the clasp.
[0023] Tel que mentionné précédemment, la fabrication d'un tel bracelet est grandement simplifiée en référence à celle des bracelets de l'état de la technique.  As mentioned above, the manufacture of such a bracelet is greatly simplified with reference to that of the bracelets of the state of the art.

[0027] Les figures 1 a et 1 b représentent des vues en perspective d'un fermoir 1 selon un mode de réalisation préféré de la présente invention, illustré respectivement depuis des premier et second côtés.  Figures 1a and 1b show perspective views of a clasp 1 according to a preferred embodiment of the present invention, respectively illustrated from first and second sides.
[0028] Le fermoir 1 est du type à boucle 2 destinée à être rendue solidaire d'une première extrémité libre d'un bracelet (non illustré), portée par un premier brin, par un premier montant transversal 4. The clasp 1 is of the loop type 2 intended to be secured to a first free end of a bracelet (not shown), carried by a first strand, by a first transverse amount 4.
[0029] Le prem ier montant transversal 4 com prend u ne barre principale 6 allongée et orientée suivant une direction transversale en référence à la direction longitudinale du bracelet. La barre principale 6 se termine à chaque extrémité par une portion pliée définissant un rebord 8. The first transverse upright 4 comprises a main bar 6 which is elongated and oriented in a transverse direction with reference to the longitudinal direction of the bracelet. The main bar 6 ends at each end by a folded portion defining a flange 8.
[0030] La boucle 2 comprend par ailleurs un second montant transversal 10 et deux montants latéraux 1 1 , 12, ces trois montants étant formés d'une seule pièce ici, à titre illustratif non limitatif, et conformés en U. The loop 2 further comprises a second transverse amount 10 and two lateral uprights 1 1, 12, these three amounts being formed in one piece here, by way of non-limiting illustration, and shaped in U.
[0031] Chacun des montants latéraux 1 1 , 12 présente un trou traversant (référence numérique 14 sur la figure 2) dans lequel est engagée une vis 16 de fixation du premier montant transversal 4. De manière avantageuse non limitative, chaque vis 16 peut être montée sur le fermoir de manière à pouvoir pivoter librement en référence au montant latéral correspondant, son pied étant vissé dans le rebord 8 correspondant. Bien entendu, l'inverse est également possible, c'est-à-dire que les vis soient libres de pivoter dans les rebords 8 en étant fixes dans les montants latéraux. Each of the lateral uprights 1 1, 12 has a through hole (numeral 14 in Figure 2) in which is engaged a screw 16 for fixing the first transverse amount 4. Advantageously but not limited to, each screw 16 may be mounted on the clasp so as to be able to freely rotate with reference to the corresponding lateral upright, its foot being screwed into the corresponding rim 8. Of course, the opposite is also possible, that is to say that the screws are free to pivot in the flanges 8 being fixed in the lateral uprights.
[0032] La boucle 2 présente une ouverture centrale 18 pour définir un passage pour la seconde extrémité libre du bracelet, portée par un second brin. The loop 2 has a central opening 18 to define a passage for the second free end of the bracelet, carried by a second strand.
[0033] Pour assurer la fermeture et le verrouillage du bracelet au moyen du fermoir selon la présente invention, ce dernier comporte, d'une part, un organe de fixation destiné à assurer la liaison du premier montant transversal à la première extrémité libre du bracelet et, d'autre part, un organe de verrouillage destiné à coopérer avec la seconde extrémité libre du bracelet pour assurer son verrouillage suivant la direction longitudinale du bracelet. To ensure the closure and locking of the bracelet by means of the clasp according to the present invention, the latter comprises, on the one hand, a fastener for connecting the first transverse amount to the first free end of the wristband and, on the other hand, a locking member intended to cooperate with the second free end of the bracelet to ensure its locking in the longitudinal direction of the bracelet.
[0034] Plus précisément, la forme du premier montant transversal 4 définit un logement pour la première extrémité libre du bracelet, la barre principale 6 en définissant une première paroi, constituant un fond, et les rebords 8 des parois latérales.  More specifically, the shape of the first transverse upright 4 defines a housing for the first free end of the bracelet, the main bar 6 defining a first wall, constituting a bottom, and the flanges 8 of the side walls.
[0035] Ce logement comporte un organe de fixation de la première extrémité libre du bracelet, réalisé ici sous la forme de deux plots 20, sensiblement en formes générales de champignons. Plus précisément, chaque plot 20 présente une première portion 22 s'étendant suivant une direction sensiblement perpendiculaire depuis la barre principale 6 et de forme cylindrique. La première portion 22 est surmontée d'une seconde portion 24, de dimensions transversales supérieures à celles de la première portion 22, pour assurer une retenue de la première extrémité libre du bracelet lorsqu'elle est engagée sur la première portion 22.  This housing comprises a fastener of the first free end of the bracelet, made here in the form of two studs 20, substantially in general shapes of mushrooms. More specifically, each stud 20 has a first portion 22 extending in a substantially perpendicular direction from the main bar 6 and cylindrical. The first portion 22 is surmounted by a second portion 24 of transverse dimensions greater than those of the first portion 22, to ensure retention of the first free end of the bracelet when engaged on the first portion 22.
[0036] Grâce à une telle structure de l'organe de fixation, la fabrication du bracelet est simplifiée. Il suffit de ménager deux trous traversants, suivant la direction de l'épaisseur du bracelet, dans l'une de ses extrémités libres, destinés à coopérer avec les deux plots 20. Ainsi, dans le cas d'un bracelet en cuir, par exemple, il n'est pas nécessaire de replier une portion du bracelet, ni de procéder à un bordage ou à une couture.  With such a structure of the fastener, the manufacture of the bracelet is simplified. Just make two holes through, in the direction of the thickness of the bracelet, in one of its free ends, intended to cooperate with the two studs 20. Thus, in the case of a leather bracelet, for example it is not necessary to fold a portion of the bracelet, or to make a pleating or sewing.
[0037] L'organe de verrouillage du second brin du bracelet présente une structure similaire à celle de l'organe de fixation de la première extrémité. Celui-ci comprend un plot 26 porté par le second montant transversal 10, de forme et dimensions similaires à celles des plots 20.  The locking member of the second strand of the bracelet has a similar structure to that of the fastener of the first end. This comprises a stud 26 carried by the second transverse upright 10, of shape and dimensions similar to those of the studs 20.
[0038] Ainsi, le plot 26 est destiné à coopérer avec un trou (non visible) parmi une série de trous ménagés dans le brin de bracelet correspondant, de manière similaire au mode de coopération entre un ardillon conventionnel et un bracelet, pour assurer le verrouillage de ce brin de bracelet suivant la direction longitudinale du bracelet.  Thus, the stud 26 is intended to cooperate with a hole (not visible) among a series of holes in the corresponding bracelet strand, similar to the mode of cooperation between a conventional barb and a bracelet, to ensure the locking of this bracelet strand in the longitudinal direction of the bracelet.
[0039] De ce fait, le brin de bracelet correspondant peut être conventionnel en référence aux bracelets connus de l'état de la technique. [0040] On notera que les plots 20, d'une part, et le plot 26, d'autre part, sont agencés de part et d'autre d'un plan médian (référence P sur la figure 2) passant par les deux montants transversaux 4 et 10, pour coopérer dans les deux cas avec le brin de bracelet correspondant. Therefore, the corresponding bracelet strand may be conventional with reference to bracelets known from the state of the art. Note that the pads 20, on the one hand, and the pad 26, on the other hand, are arranged on either side of a median plane (reference P in Figure 2) passing through both transverse uprights 4 and 10, to cooperate in both cases with the corresponding bracelet strand.
[0041] La figure 2 représente une vue latérale d'un détail du fermoir des figures 1 a et 1 b, illustrant un détail de construction. Plus précisément, seuls le second montant transversal 10 et les montants latéraux 1 1 , 12 ont été représentés, le premier montant transversal 4 ayant été omis sur cette figure. [0041] Figure 2 shows a side view of a detail of the clasp of Figures 1a and 1b, illustrating a construction detail. More precisely, only the second transverse upright 10 and the lateral uprights 11, 12 have been represented, the first transverse upright 4 having been omitted from this figure.
[0042] Il apparaît de la figure 2 que le second montant transversal 10 est incliné en référence à la direction des montants latéraux 1 1 , 12, pour faciliter l'insertion du second brin de bracelet dans le passage 18 de la boucle 2, c'est-à-dire sans qu'il soit nécessaire de le plier fortement. It appears from Figure 2 that the second transverse upright 10 is inclined with reference to the direction of the lateral uprights 1 1, 12, to facilitate the insertion of the second strap strand in the passage 18 of the loop 2, c that is, without having to bend it strongly.
[0043] Par ailleurs, un détail de construction est particulièrement visible sur la figure 2. In addition, a construction detail is particularly visible in FIG. 2.
[0044] Chaque montant latéral 1 1 , 12 présente une découpe 30, à proximité de son trou 14, définissant deux butées 32 et 34.  Each lateral upright 1 1, 12 has a cutout 30, near its hole 14, defining two stops 32 and 34.
[0045] Chacune de ces butées 32, 34 est destinée à coopérer avec un doigt (référence numérique 36 sur la figure 1 b) solidaire du premier montant transversal 4, dans le but de définir une plage angulaire pour le pivotement du premier montant transversal 4 en référence aux montants latéraux 1 1 , 12. Each of these stops 32, 34 is intended to cooperate with a finger (reference numeral 36 in Figure 1 b) integral with the first transverse amount 4, in order to define an angular range for the pivoting of the first transverse amount 4 with reference to lateral amounts 1 1, 12.
[0046] Une telle caractéristique permet de limiter la rotation relative entre les montants latéraux et le premier montant transversal qui, si elle devait être trop importante, rendrait plus difficile la mise en place du bracelet sur le poignet du porteur.  Such a feature allows to limit the relative rotation between the lateral uprights and the first transverse amount which, if it were to be too important, would make it more difficult to place the bracelet on the wrist of the wearer.
[0047] Bien entendu, il est possible de définir une telle plage angulaire de pivotement par la mise en œuvre d'une seule découpe 30, en relation avec un seul doigt 36 sans sortir du cadre de l'invention.  Of course, it is possible to define such an angular range of pivoting by the implementation of a single cutout 30, in relation with a single finger 36 without departing from the scope of the invention.
[0048] On notera que la plage angulaire pourra notamment aller d'environ 15 à 60 degrés, préférablement de 30 à 45 degrés. It will be noted that the angular range may especially range from about 15 to 60 degrees, preferably from 30 to 45 degrees.
[0049] La description qui précède s'attache à décrire un mode de réalisation particulier à titre d'illustration non limitative et, l'invention n'est pas limitée à la mise en œuvre de certaines caractéristiques particulières qui viennent d'être décrites, comme par exemple la forme spécifiquement illustrée et décrite de la boucle 2. En effet, il est par exemple envisageable d'avoir une telle boucle ne comportant pas de second montant transversal, les deux montants latéraux se rejoignant pour définir une forme générale triangulaire ou sensiblement semi-circulaire de la boucle dans ce cas. Le plot 26 serait alors préférablement agencé dans la région de la jonction entre les deux montants latéraux. The foregoing description seeks to describe a particular embodiment by way of non-limiting illustration and the invention is not limited. to the implementation of certain particular characteristics which have just been described, for example the specifically illustrated and described form of the loop 2. Indeed, it is for example conceivable to have such a loop having no second amount. transversely, the two lateral uprights joining to define a general triangular or substantially semicircular shape of the loop in this case. The pad 26 would then preferably be arranged in the region of the junction between the two lateral uprights.
[0050] L'homme du métier ne rencontrera pas de difficulté particulière pour adapter le contenu de la présente divulgation à ses propres besoins et mettre en œuvre un fermoir pour bracelet de pièce d'horlogerie répondant en partie aux caractéristiques qui viennent d'être présentées, sans sortir du cadre de la présente invention. The skilled person will not encounter any particular difficulty to adapt the content of the present disclosure to his own needs and implement a clasp for a timepiece bracelet in part to meet the characteristics that have just been presented without departing from the scope of the present invention.
[0051] On notera par exemple que la provision des découpes 30 n'est pas indispensable à la mise en œuvre de la présente invention. Elle permet toutefois d'améliorer l'utilisation du fermoir et correspond ainsi à un mode de réalisation préféré. It will be noted, for example, that the provision of blanks 30 is not essential for the implementation of the present invention. However, it improves the use of the clasp and thus corresponds to a preferred embodiment.
[0052] Par ailleurs, on notera que le fermoir selon la présente invention n'est pas limité à la mise en œuvre d'un organe de verrouillage tel que celui décrit et illustré, à savoir le plot 26. En effet, il est également possible de prévoir qu'un ardillon similaire aux ardillons de l'état de la technique est rendu solidaire du premier montant transversal pour coopérer avec les trous du second brin de bracelet. Dans ce cas, bien entendu, il conviendrait de prévoir une découpe dans la première extrémité libre du bracelet correspondant pour définir un passage pour l'ardillon. Furthermore, it will be noted that the clasp according to the present invention is not limited to the implementation of a locking member such as that described and illustrated, namely the stud 26. Indeed, it is also possible to provide a barb similar to the barbs of the state of the art is secured to the first transverse amount to cooperate with the holes of the second bracelet strand. In this case, of course, it should be provided a cut in the first free end of the corresponding bracelet to define a passage for the barb.
[0053] On notera également que l'orientation du plot 26, en référence au second montant transversal, est susceptible d'être différente de ce qui a été décrit, sans sortir du cadre de l'invention, notamment en fonction de l'inclinaison que présente le second montant transversal par rapport aux montants latéraux. En effet, dans tous les cas, il est avantageux de prévoir que le plot 26 est sensiblement perpendiculaire au second brin de bracelet lorsque celui-ci est en place dans le fermoir.  Note also that the orientation of the stud 26, with reference to the second transverse amount, is likely to be different from what has been described, without departing from the scope of the invention, in particular depending on the inclination that presents the second transverse amount relative to the lateral amounts. Indeed, in all cases, it is advantageous to provide that the stud 26 is substantially perpendicular to the second strand bracelet when it is in place in the clasp.
