Description

Domaine techniqueTechnical area

La présente invention se rapporte au domaine des fermoirs dits de sécurité pour des articles de bijouterie et plus particulièrement pour des bracelets de montre. On entend par fermoir de sécurité un fermoir présentant des garanties contre une ouverture inopinée qui pourrait entraîner la perte de l'article de bijouterie sur lequel il est monté.The present invention relates to the field of so-called security clasps for jewelery articles and more particularly for watch straps. A safety clasp means a clasp with guarantees against an unexpected opening that could lead to the loss of the jewelry item on which it is mounted.

Etat de la techniqueState of the art

Dans le domaine des articles de bijouterie, et celui bracelets de montre, il est bien connu des fermoirs dits de sécurité comprenant une partie mâle constituée d'un tenon en forme générale de T et une partie femelle comportant un logement de forme correspondante ou une fente apte à recevoir ledit tenon.In the field of jewelery articles, and that of watch straps, it is well known security clasps comprising a male part consisting of a tenon generally T-shaped and a female part comprising a housing of corresponding shape or a slot adapted to receive said tenon.

De tels fermoirs sont notamment décrits dans les documents US 5,774,957 , CH 35922 et CH 645 003 .Such clasps are described in particular in the documents US 5,774,957 , CH 35922 and CH 645 003 .

Le document US 5,774,957 décrit un fermoir conçu pour fixer deux éléments l'un à l'autre, en particulier, des pièces de bijouterie, et permettant d'effectuer une fermeture de sûreté. Ce fermoir comprend un élément récepteur possédant une surface définissant une fente et un élément d'accouplement possédant une tige en forme générale de T pouvant être placée amovible dans la fente, de manière à accoupler de façon détachable l'élément d'accouplement à l'élément récepteur. L'élément d'accouplement est mobile depuis une position verticale dans laquelle on peut l'introduire dans l'élément récepteur et l'en retirer, jusqu'à une deuxième position, ou position horizontale, dans laquelle il est retenu de façon élastique par l'élément récepteur.The document US 5,774,957 describes a clasp designed to attach two elements to one another, in particular, jewelry pieces, and to perform a safety closure. The clasp includes a receiver member having a slot defining surface and a coupling member having a generally T-shaped shank that can be releasably disposed in the slot to releasably couple the coupling member to the shank. receiving element. The coupling element is movable from a vertical position in which it can be introduced into and removed from the receiving element to a second position, or horizontal position, in which it is resiliently retained by the receiving element.

Bien que l'interaction entre l'élément d'accouplement et l'élément récepteur permette d'obtenir une fermeture plus difficile à ouvrir involontairement, la tige est quand même susceptible de sortir de la fente lors de certains mouvements du poignet de la personne portant la pièce de bijouterie.Although the interaction between the coupling element and the receiving element makes it possible to obtain a closure that is more difficult to open involuntarily, the rod is nevertheless capable of coming out of the slot during certain movements of the wrist of the person carrying the piece of jewelry.

Le document CH 35922 décrit un fermoir comprenant une partie mâle solidaire d'un premier brin d'un bracelet et constituée d'un tenon en forme de T et une partie femelle solidaire d'un second brin d'un bracelet, constituée d'une pièce sensiblement parallélépipédique comportant un évidement pratiqué depuis la face supérieure de ladite pièce, ledit évidement présentant une forme correspondante de T.The document CH 35922 discloses a clasp comprising a male portion integral with a first strand of a bracelet and consisting of a T-shaped tenon and a female part secured to a second strand of a bracelet, consisting of a substantially parallelepipedal piece comprising a recess made from the upper face of said workpiece, said recess having a corresponding shape of T.

Ce type de fermoir présente l'inconvénient de ne pas être efficace lors que la tension sur les brins du bracelet est insuffisante. En effet, lorsque les brins du bracelet ne sont plus sous tension, le tenon en forme de T de la partie mâle est susceptible de se désengager du logement de la partie femelle rendant le fermoir inopérant.This type of clasp has the disadvantage of not being effective when the tension on the strands of the bracelet is insufficient. Indeed, when the strands of the bracelet are no longer under tension, the T-shaped post of the male part is likely to disengage from the housing of the female part making the clasp inoperative.

Le document CH 645 003 décrit un fermoir pour bracelet de montre. Une des branches du bracelet est munie d'une monture dans laquelle la branche peut coulisser pour ajuster la longueur, avant d'être fixée, cette monture présentant une ouverture supérieure en forme de T, avec une battue en retrait inférieur sous les parties de bord rétrécissant l'ouverture. Une pièce de fermeture est fixée à l'extrémité de l'autre branche de bracelet, et elle comprend une langue en forme de T, s'engageant dans l'ouverture et se crochant dans la battue. Un couvercle se rabat sur le dispositif de fermoir lorsque la langue est ainsi crochée, et une projection disposée sous ce couvercle verrouille alors la fermeture en empêchant la langue de se dégager de la battue.The document CH 645 003 describes a clasp for a watch strap. One of the branches of the bracelet is provided with a frame in which the branch can slide to adjust the length, before being fixed, this mount having an upper opening in the shape of a T, with a batten recessed lower under the edge parts narrowing the opening. A closure piece is attached to the end of the other wristband branch, and includes a T-shaped tongue, engaging in the opening and notching in the thimble. A lid is folded over the clasp device when the tongue is thus hooked, and a projection disposed under this cover then locks the closure by preventing the tongue from disengaging the batter.

Ce type de fermoir présente l'inconvénient de ne pas pouvoir éviter une ouverture inopinée. En effet, en cas d'ouverture du couvercle, lorsqu'il s'accroche à un vêtement par exemple, la langue est susceptible de se dégager de l'ouverture en T de la monture par un simple mouvement de translation, ledit mouvement de translation pouvant être induit par une diminution de la tension entre les branches du bracelet.This type of clasp has the disadvantage of not being able to avoid an unexpected opening. Indeed, in case of opening of the lid, when it clings to a garment for example, the tongue is likely to disengage from the opening T of the frame by a simple translational movement, said translational movement can be induced by a decrease in tension between the branches of the bracelet.

La présente invention a donc pour but de proposer un fermoir de sécurité pour des articles de joaillerie permettant d'éviter une séparation intempestive des parties mâle et femelle lorsque les banches du bracelet, ou similaire, ne sont plus sous tension notamment.The present invention therefore aims to provide a safety clasp for jewelery articles to avoid inadvertent separation of the male and female parts when the strap of the bracelet, or the like, are no longer under tension in particular.

Divulguation de l'inventionDisclosure of the invention

De façon plus précise, et selon un premier aspect, l'invention concerne un fermoir pour articles de bijouterie en vue d'obtenir la jonction de deux branches dudit article de bijouterie comprenant au moins une partie mâle constituée d'un tenon en forme générale de T et une partie femelle comportant un logement apte à recevoir ledit tenon ; ledit fermoir est remarquable en ce que la partie femelle est constituée d'une première pièce sensiblement parallélépipédique dont l'une des extrémités comporte, sur sa face inférieure, un évidement débouchant sur l'extrémité distale de ladite pièce et, sur sa face supérieure, une rainure en communication, dans sa partie centrale avec ledit évidement formant à l'extrémité distale de la pièce une entretoise reliant les deux bords inférieurs de la rainure, la paroi supérieure de l'évidement comportant un ergot transversal s'étendant perpendiculairement à la rainure et de part et d'autre de ladite rainure, et en ce que la partie mâle est constituée d'une seconde pièce sensiblement parallélépipédique munie d'un tenon en forme générale de T dont la tige est issue de la face supérieure de la pièce et dont la tête s'étend à l'extrémité libre de ladite tige, perpendiculairement et en dessous de cette dernière, ladite tige comportant sur sa face inférieure un ergot s'étendant transversalement de telle sorte que, après l'introduction du tenon dans le logement de la partie femelle, à travers la rainure, la tige du tenon s'étende dans la rainure de la partie femelle, la tête du tenon prenne appui sur l'ergot de la partie femelle et l'ergot du tenon prenne appui sur la paroi proximale de l'entretoise de partie femelle afin d'éviter une séparation intempestive des parties mâle et femelle notamment par basculement.More specifically, and according to a first aspect, the invention relates to a clasp for jeweler's articles in order to obtain the junction of two branches of said jewelery article comprising at least one male part consisting of a tenon in the general shape of a piece of jewelery. T and a female part having a housing adapted to receive said tenon; said clasp is remarkable in that the female part consists of a first substantially parallelepipedal part, one end of which comprises, on its lower face, a recess opening on the distal end of said part and, on its upper face, a groove in communication, in its central part with said recess forming at the distal end of the part a spacer connecting the two lower edges of the groove, the upper wall of the recess having a transverse lug extending perpendicular to the groove and on either side of said groove, and in that the male part consists of a second substantially parallelepipedal part provided with a generally T-shaped post whose stem is coming from the upper face of the part and whose head extends at the free end of said rod, perpendicularly and below it, said rod having on its underside ure a lug extending transversely such that, after the introduction of the tenon in the housing of the female part, through the groove, the shank of the post extends into the groove of the female part, the head of the tenon bears on the lug of the female part and the lug of the post bears on the proximal wall of the female part spacer to prevent inadvertent separation of the male and female parts in particular by tilting.

On comprend bien que, contrairement aux fermoirs de l'art antérieur, le tenon en T de la partie mâle ne peut être introduit dans la rainure de la partie femelle qu'en procédant à une rotation de 90° autour de l'axe longitudinal de la partie mâle et en inclinant d'au moins 45° ladite partie mâle par rapport à la partie femelle, et inversement pour le retrait. D'autre part, une fois la partie mâle coopérant avec la partie femelle. Cette double rotation ne peut que difficilement résulter d'un mouvement aléatoire de sorte qu'une ouverture intempestive du fermoir est évitée.It is clearly understood that, unlike the clasps of the prior art, the T-piece of the male part can be introduced into the groove of the female part only by proceeding with a 90 ° rotation about the longitudinal axis of the male part and inclining at least 45 ° said male part relative to the female part, and vice versa for the withdrawal. On the other hand, once the male part cooperating with the female part. This double rotation can hardly result from a random movement so that inadvertent opening of the clasp is avoided.

De manière avantageuse, les parois distales des pièces de la partie mâle et respectivement femelle présentent un plan concave et respectivement convexe cylindrique. De cette manière, lorsque les parties mâle et femelle sont accouplées, il n'y a pas de jeu entre lesdites parties mâle et femelle, ces plans concave et convexe cylindriques permettent une rotation d'au moins 45° de la partie mâle par rapport à la partie femelle lors de l'ouverture ou de la fermeture du fermoir sans qu'il n'y ait de jeu entre les deux parties.Advantageously, the distal walls of the parts of the male and female portions respectively have a concave and respectively convex cylindrical plane. In this way, when the male and female parts are coupled, there is no clearance between said male and female parts, these cylindrical concave and convex planes allow a rotation of at least 45 ° of the male part with respect to the female part when opening or closing the clasp without there being play between the two parts.

De préférence, l'axe du plan concave et convexe cylindrique est positionné aux deux tiers de la longueur du tenon.Preferably, the axis of the concave and convex cylindrical plane is positioned at two thirds of the length of the tenon.

Par ailleurs, la tête du tenon est avantageusement plate procurant une plus grande stabilité de la partie mâle par rapport à la partie femelle en position de fermeture dudit fermoir.Moreover, the head of the tenon is advantageously flat providing greater stability of the male part relative to the female part in the closed position of said clasp.

De plus, la tête du tenon présente une forme sensiblement parallélépipédique dont les deux arêtes distales sont arrondies. La forme arrondie des deux arêtes distales permet de faciliter l'introduction de la tête du tenon dans le logement de la partie femelle à travers la rainure débouchant dans ledit logement.In addition, the head of the post has a substantially parallelepiped shape whose two distal edges are rounded. The rounded shape of the two distal edges facilitates insertion of the tenon head into the housing of the female part through the groove opening into said housing.

Mode de réalisation de l'inventionEmbodiment of the invention

On décrira ci-après un fermoir dit de sécurité pour un bracelet comportant deux paires de branches souples, telles que des branches sous forme de lanières de cuir ou similaire ; toutefois, il est bien évident que le fermoir pourra être adapté à tout type de bracelet, et plus généralement à tout type de pièces de joailleries sans pour autant sortir du cadre de l'invention.Hereinafter will be described a security clasp for a bracelet comprising two pairs of flexible branches, such as branches in the form of leather strips or the like; However, it is obvious that the clasp can be adapted to any type of bracelet, and more generally to any type of jewelry without departing from the scope of the invention.

En se référant à la figure 1, le fermoir selon l'invention pour articles de bijouterie en vue d'obtenir la jonction de deux branches dudit article de bijouterie comprend une partie mâle 1 et une partie femelle 2, chacune des parties mâle 1 et femelle 2 étant solidarisée, par tous moyens appropriés à une branche de l'article de joaillerie.Referring to the figure 1 , the clasp according to the invention for jewelery articles in order to obtain the junction of two branches of said jewelery article comprises a male part 1 and a female part 2, each of the male 1 and female 2 parts being secured, by any means suitable for a branch of the jewelry item.

En référence aux figures 1 à 4, la partie femelle 2 est constituée d'une première pièce sensiblement parallélépipédique 3 dont l'une des extrémités, à savoir son extrémité distale, comporte, sur sa face inférieure, un évidement 4 débouchant sur l'extrémité distale de ladite pièce 3 et comporte, sur sa face supérieure, une rainure 5 en communication, dans sa partie centrale, avec ledit évidement 4 formant ainsi à l'extrémité distale de la pièce 3 une entretoise 6 reliant les deux bords inférieurs de ladite rainure 5. On entend par extrémité distale de la pièce 3, l'extrémité de la pièce 3 opposée au point de fixation de la branche de la pièce de joaillerie à la pièce femelle 2. Ledit évidement 4 présente une forme sensiblement parallélépipédique et la rainure 5 présente une section droite quadrilatérale, en l'espèce une section droite rectangulaire. Dans cet exemple particulier de réalisation, la rainure 5 s'étend sur un peu moins que la moitié de la longueur de la pièce 3 et l'entretoise 6 présente une largeur sensiblement égale à un tiers de la longueur de la rainure 5. La face supérieure de l'entretoise 6 s'étend au même niveau que la paroi supérieure de l'évidement 4 pratiqué dans la pièce 3. Par ailleurs, la paroi supérieure de l'évidement 4 comporte un ergot transversal 7 s'étendant perpendiculairement à la rainure 5 et de part et d'autre de ladite rainure 5.With reference to Figures 1 to 4 , the female part 2 consists of a first substantially parallelepipedal part 3, one of its ends, namely its distal end, comprises, on its lower face, a recess 4 opening on the distal end of said part 3 and comprises , on its upper face, a groove 5 in communication, in its central part, with said recess 4 thus forming at the distal end of the part 3 a spacer 6 connecting the two lower edges of said groove 5. Distal end is understood of the piece 3, the end of the piece 3 opposite the point of attachment of the branch of the piece of jewelry to the female part 2. Said recess 4 has a substantially parallelepiped shape and the groove 5 has a quadrilateral cross section, in the species has a rectangular cross section. In this particular embodiment, the groove 5 extends over a little less than half the length of the part 3 and the spacer 6 has a width substantially equal to one third of the length of the groove 5. The face upper of the spacer 6 extends at the same level as the upper wall of the recess 4 formed in the room 3. Furthermore, the upper wall of the recess 4 has a transverse lug 7 extending perpendicular to the groove 5 and on both sides of said groove 5.

En référence aux figures 1 et 5 à 7, la partie mâle 1 est constituée d'une seconde pièce sensiblement parallélépipédique 8 munie d'un tenon 9 en forme générale de T dont la tige 10 est issue de la face supérieure de la pièce 8 et dont la tête 11 s'étend à l'extrémité libre de ladite tige 10, perpendiculairement et en dessous de cette dernière. Ladite tige 10 comporte sur sa face inférieure un ergot 12 s'étendant transversalement et faisant saillie sous la tête 11 du tenon 9. Dans cette forme de réalisation particulière, ledit ergot 12 fait saillie sous la tige 10, dans la partie médiane de ladite tige. La tige 10 du tenon 9 présente une section droite quadrilatérale, en l'espèce une section droite rectangulaire et la tête 11 du tenon 9 est plate et présente une forme sensiblement parallélépipédique dont les deux arêtes distales sont arrondies afin de faciliter l'introduction du tenon 9 dans l'évidement 4 de la partie femelle 2. Ainsi, après l'introduction du tenon 9 dans l'évidement 4 de la partie femelle 2, à travers la rainure 5, la tige 10 du tenon 9 s'étende dans la rainure 5 de la partie femelle 2, la tête du tenon 11 prenne appui sur l'ergot 7 de la partie femelle 2 et l'ergot 12 du tenon 9 prenne appui sur la paroi proximale de l'entretoise 6 de partie femelle 2 afin d'éviter une séparation intempestive des parties mâle 1 et femelle 2 notamment par basculement, comme il sera détaillé plus loin. On notera que, lorsque la partie mâle 1 et la partie femelle 2 sont assemblées, la face supérieure du fermoir présente une surface plane sans creux ni saillie présentant un aspect esthétique particulièrement propre.With reference to figures 1 and 5 to 7 , the male part 1 consists of a second substantially parallelepipedal part 8 provided with a pin 9 in the general shape of T whose stem 10 comes from the upper face of the part 8 and whose head 11 extends to the free end of said rod 10, perpendicularly and below the latter. Said rod 10 has on its underside a lug 12 extending transversely and projecting under the head 11 of the pin 9. In this form of particular embodiment, said lug 12 projects under the rod 10, in the middle part of said rod. The rod 10 of the post 9 has a quadrilateral cross section, in this case a rectangular cross section and the head 11 of the post 9 is flat and has a substantially parallelepiped shape whose two distal edges are rounded to facilitate the introduction of the tenon 9 in the recess 4 of the female part 2. Thus, after the introduction of the pin 9 in the recess 4 of the female part 2, through the groove 5, the rod 10 of the tenon 9 extends into the groove 5 of the female part 2, the head of the post 11 bears on the lug 7 of the female part 2 and the lug 12 of the post 9 bears on the proximal wall of the spacer 6 of the female part 2 in order to avoid untimely separation of the male 1 and female 2 parts in particular by tilting, as will be detailed below. Note that when the male part 1 and the female part 2 are assembled, the upper face of the clasp has a flat surface without hollow or protrusion having a particularly clean aesthetic appearance.

Par ailleurs, en référence aux figures 1, 2, 3 et 6, les parois distales des pièces de la partie mâle 1 et respectivement femelle 2 présentent un plan concave 13 et respectivement convexe 14 cylindrique. L'axe du plan concave et convexe cylindrique des parois distales des pièces de la partie mâle 1 et femelle 2 est positionné environ aux deux tiers de la longueur du tenon 9 ou au niveau de la tête 11 du tenon 9. Cette configuration permet, lorsque les parties mâle 1 et femelle 2 sont accouplées, de ne pas avoir de jeu entre lesdites parties mâle 1 et femelle 2, ces plans concave 13 et convexe 14 cylindriques permettant une rotation d'au moins 45° de la partie mâle 1 par rapport à la partie femelle 2 lors de l'ouverture ou de la fermeture du fermoir sans qu'il n'y ait de jeu entre les deux parties comme il sera détaillé plus loin.Moreover, with reference to Figures 1, 2, 3 and 6 , the distal walls of the parts of the male part 1 and respectively female 2 have a concave plane 13 and respectively convex 14 cylindrical. The axis of the concave and convex cylindrical plane of the distal walls of the parts of the male part 1 and female 2 is positioned about two-thirds of the length of the post 9 or at the level of the head 11 of the post 9. This configuration allows, when the male 1 and female 2 parts are coupled, to have no play between said male 1 and female 2, these concave planes 13 and convex 14 cylindrical allowing a rotation of at least 45 ° of the male part 1 relative to the female part 2 when opening or closing the clasp without there being play between the two parts as will be detailed below.

De plus, en référence aux figures 1, 3 et 6, la partie mâle 1 et la partie femelle 2 comprennent des moyens de fixation 15 d'une branche de l'article de bijouterie, non représentée sur les figures. Ces moyens de fixation consistent, dans cet exemple particulier de réalisation, en des moyens de sertissage. Chaque moyen de sertissage est constitué de deux trous 16 parallèles et contigus, les trous 16 étant ainsi en communication, pratiqués depuis la paroi proximale de la partie mâle 1 et respectivement femelle 2, et apte à recevoir une branche de l'article de joaillerie, et de une paire de trous taraudés 17 pratiqués depuis la paroi inférieure de la partie mâle 1 et respectivement femelle 2, au niveau de la jonction des deux trous 16, chaque paire de trous taraudés 17 traversant les trous 16 recevant la branche et étant apte à recevoir une vis de sertissage, non représentée sur les figures. Lesdits trous 16 sont destinés à recevoir une branche souple d'une pièce de joaillerie, telle qu'une branche constitué de deux lanières de cuir par exemple.In addition, with reference to Figures 1, 3 and 6 , the male part 1 and the female part 2 comprise fastening means 15 of a branch of the jewelery article, not shown in the figures. These fixing means consist, in this particular embodiment, in crimping means. Each crimping means consists of two parallel and contiguous holes 16, the holes 16 thus being in communication, made from the proximal wall of the male 1 and female 2 respectively, and adapted to receive a branch of the jewelery article, and a pair of threaded holes 17 made from the lower wall of the male 1 and female 2 respectively, at the junction of the two holes 16, each pair of threaded holes 17 passing through the holes 16 receiving the branch and being adapted to receive a crimping screw, not shown in the figures. Said holes 16 are intended to receive a flexible branch of a piece of jewelry, such as a branch consisting of two strips of leather for example.

Toutefois, il est bien évident que les moyens de sertissage pourront ne comporter qu'un trou 16 et que les branches de la pièce de joaillerie pourront être souples ou rigides et présenter une forme quelconque. Par ailleurs, il va de soi que les moyens de fixation 15 pourront être substitués par tous autres moyens de fixation bien connus de l'homme du métier sans pour autant sortir du cadre de l'invention.However, it is obvious that the crimping means may have only one hole 16 and the branches of the piece of jewelery may be flexible or rigid and have any shape. Furthermore, it goes without saying that the fixing means 15 may be substituted by any other fastening means well known to those skilled in the art without departing from the scope of the invention.

On expliquera maintenant le fonctionnement du fermoir selon l'invention en référence aux figures 8a à 8d.We will now explain the operation of the clasp according to the invention with reference to Figures 8a to 8d .

En référence à la figure 8a, la partie mâle 1 est présentée au droit de la partie femelle 2, puis la partie mâle est pivotée suivant un angle d'environ 90° autour de son axe longitudinal, comme représenté par la flèche a, et inclinée suivant un angle compris entre 45° et 90°, comme indiqué par la flèche b.With reference to the figure 8a , the male part 1 is presented to the right of the female part 2, then the male part is rotated at an angle of about 90 ° about its longitudinal axis, as represented by the arrow a, and inclined at an angle between 45 ° and 90 °, as indicated by the arrow b.

La partie mâle 2 ainsi pivotée et inclinée, en référence à la figure 8b, est alors présentée au dessus de la partie femelle 1, puis la tête 11 du tenon 9 de la partie mâle 2 est introduite dans l'évidement 4 de la partie femelle 1 en passant à travers la rainure 5 et le trou de communication entre la rainure 5 et l'évidement 4, jusqu'à ce que la totalité de la tête 11 s'étende dans l'évidement 4.The male part 2 thus pivoted and inclined, with reference to the figure 8b , is then presented above the female part 1, then the head 11 of the post 9 of the male part 2 is introduced into the recess 4 of the female part 1 by passing through the groove 5 and the communication hole between the groove 5 and the recess 4, until the entire head 11 extends into the recess 4.

En référence à la figure 8c, la partie mâle 2 est alors pivotée autour de son axe de longitudinal suivant un angle de 90°, dans un sens de rotation opposé à celui de la première rotation de 90° préalablement à l'introduction de la tête 11 du tenon 9 dans l'évidement 4, puis la partie mâle 2 est pivotée par rapport à la partie femelle 1, comme indiqué par la flèche c, jusqu'à ce que la tige 10 du tenon 9 s'étende intégralement dans la rainure 5 de la partie femelle 1. Dans cette position, en référence à la figure 8d, la tête du tenon 11 prend appui sur l'ergot 7 de la partie femelle 2 et l'ergot 12 du tenon 9 prend appui sur la paroi proximale de l'entretoise 6 de partie femelle 2 afin d'éviter une séparation intempestive des parties mâle 1 et femelle 2 notamment par basculement. En effet, pour désolidariser la partie mâle 1 de la partie femelle 2, il est nécessaire de procéder aux étapes inverses précédemment décrites à savoir incliner vers le haut la partie mâle 1 par rapport à la partie femelle 2, pivoter la partie mâle 1 autour de son axe longitudinal d'un angle de 90° puis de retirer la tête 11 de l'évidement 4 de la partie femelle 2. Cette double rotation ne peut que difficilement résulter d'un mouvement aléatoire de sorte qu'une ouverture intempestive du fermoir est évitée.With reference to the figure 8c , the male part 2 is then rotated about its longitudinal axis at an angle of 90 °, in a direction of rotation opposite that of the first rotation of 90 ° prior to the introduction of the head 11 of the post 9 in the recess 4, then the male part 2 is pivoted relative to the female part 1, as indicated by the arrow c , until the rod 10 of the pin 9 extends integrally in the groove 5 of the female part 1. In this position, with reference to the figure 8d , the head of the post 11 bears on the lug 7 of the female part 2 and the lug 12 of the post 9 bears on the proximal wall of the spacer 6 of the female part 2 in order to avoid an inadvertent separation of the parts male 1 and female 2 in particular by tilting. In fact, in order to separate the male part 1 from the female part 2, it is necessary to proceed with the reverse steps previously described, namely to incline the male part 1 upwards with respect to the female part 2, to pivot the male part 1 around its longitudinal axis at an angle of 90 ° and then to remove the head 11 of the recess 4 of the female part 2. This double rotation can hardly result from a random movement so that an inadvertent opening of the clasp is avoided.

Par ailleurs, il est bien évident que la partie mâle 1 et/ou la partie femelle pourront présenter une forme quelconque sans pour autant sortir du cadre de l'invention.Moreover, it is obvious that the male part 1 and / or the female part may have any shape without departing from the scope of the invention.

Enfin, il est bien évident que les exemples que l'on vient de donner ne sont que des illustrations particulières en aucun cas limitatives quant aux domaines d'application de l'invention.Finally, it is obvious that the examples that have just been given are only particular illustrations in no way limiting as to the fields of application of the invention.
