Abstract

A clasp with an interchangeable ornament includes a generally solid male clasp piece which is split longitudinally in a manner that it is transversely resilient, like a clip. A hollow female clasp piece has an insertion opening and an inwardly indented shoulder or lip at the insertion opening. When the male clasp piece is inserted into the female piece the shoulder of the female piece locks into a groove formed in the male clasp piece. Longitudinally extending slits in the peripheral wall of the female piece makes it transversely elastic and enables it to tightly hold an interchangeable ornamental sleeve that is fitted over the female piece. The ornamental sleeve in turn prevents the slit peripheral wall of the female piece from separating and assures that the inwardly indented shoulder remains locked in the groove of the male piece. Therefore, the male clasp part can not be a pulled out, except by squeezing the male piece to reduce its transverse cross-section to be smaller than the cross-section of the female piece.

Description

La présente invention a pour objet un fermoir à décor interchangeable, comprenant une première pièce mâle d'accouplement présentant une élasticité dans le sens transversal et munie d'éléments d'arrêt, et une deuxième pièce femelle d'accouplement prévue pour recevoir la première pièce d'accouplement et être solidarisée de façon sélective avec cette dernière (voir les documents cités dans le rapport de recherche).The subject of the present invention is a clasp with interchangeable decoration, comprising a first male coupling part having elasticity in the transverse direction and provided with stop elements, and a second female coupling part designed to receive the first part. and be joined selectively with the latter (see documents cited in the research report).

Un tel type de fermoir est utilisé notamment en bijouterie, et plus particulièrement pour la fermeture de colliers pré-enfilés. La pièce femelle d'accouplement qui s'emboîte sur la pièce mâle d'accouplement est alors généralement munie d'une décoration particulière. Un inconvénient majeur d'un tel type de fermoir associé par exemple à un collier pré-enfilé, ou à tout autre article de mode nécessitant une fermeture, réside dans le fait qu'un acheteur, bien que séduit par une partie de l'article proposé, par exemple les perles d'un collier, n'apprécie pas nécessairement le motif décoratif du fermoir. Inversement, un client peut apprécier la décoration d'un fermoir particulier, sans que les perles du collier enfilé associé soient à son goût. Il s'ensuit alors des opérations longues de démontage et remontage des articles pour associer un fermoir particulier présentant une décoration spécifique, avec un article décoratif qui présente lui-même un caractère décoratif particulier.Such a type of clasp is used in particular in jewelry, and more particularly for the closure of pre-strung necklaces. The female coupling part which fits on the male coupling part is then generally provided with a particular decoration. A major drawback of such a type of clasp associated for example with a pre-threaded necklace, or any other fashion item requiring closure, lies in the fact that a buyer, although seduced by a part of the item proposed, for example the pearls of a necklace, does not necessarily appreciate the decorative motif of the clasp. Conversely, a customer can appreciate the decoration of a particular clasp, without the pearls of the associated strung necklace being to his liking. It then follows long operations of disassembly and reassembly of the articles to associate a particular clasp having a specific decoration, with a decorative article which itself has a particular decorative character.

Ces opérations de démontage et remontage de fermoir exigent du temps et empêchent souvent le client d'emporter immédiatement l'article souhaité équipé d'un fermoir présentant une décoration à son goût. Par ailleurs, si par la suite le motif décoratif du fermoir n'est plus au goût de l'utilisateur, le choix d'un nouveau motif décoratif susceptible d'être adapté au même article nécessite l'achat d'un nouveau fermoir complet, ce qui, notamment pour des articles de bijouterie réalisés en métaux précieux, peut s'avérer coûteux, et entraîne en outre une opération de démontage et de remontage sur l'article concerné, des pièces d'accouplement du fermoir, qui peut rarement être faite sur le champ.These disassembly and reassembly operations of clasp require time and often prevent the customer from immediately taking the desired item equipped with a clasp presenting a decoration to his taste. Furthermore, if the decorative motif of the clasp is no longer to the taste of the user, the choice of a new decorative motif capable of being adapted to the same article requires the purchase of a new complete clasp, which, in particular for jewelry items made of precious metals, can prove to be expensive, and furthermore involves a disassembly and reassembly operation on the item concerned, clasp coupling parts, which can rarely be done. right away.

La présente invention vise précisément à remédier aux inconvénients précités et à offrir à un utilisateur la possibilité de choisir le motif décoratif d'un fermoir d'article et de modifier celui-ci à volonté, sans que ceci implique des opérations longues et complexes de démontage et remontage du fermoir sur l'article. L'invention vise ainsi plus particulièrement à permettre de réaliser de façon rapide et économique la modification de la décoration du fermoir d'un article, alors même que ce fermoir est déjà monté sur l'article.The present invention aims precisely to remedy the aforementioned drawbacks and to offer a user the possibility of choosing the decorative pattern of an article clasp and of modifying the latter at will, without this implying long and complex dismantling operations. and reassembly of the clasp on the article. The invention thus aims more particularly to allow to quickly and economically modify the decoration of the clasp of an article, even when this clasp is already mounted on the article.

Ces buts sont atteints grâce à un fermoir du type mentionné en tête de la description, dans lequel, conformément à l'invention, la deuxième pièce femelle d'accouplement présente elle-même une élasticité dans le sens transversal et un manchon décoratif amovible est engagé autour de ladite deuxième pièce femelle pour assurer le maintien du verrouillage de la première pièce mâle à l'intérieur de la seconde pièce femelle.These aims are achieved by means of a clasp of the type mentioned at the head of the description, in which, in accordance with the invention, the second female coupling part itself has elasticity in the transverse direction and a removable decorative sleeve is engaged. around said second female part to maintain the locking of the first male part inside the second female part.

De préférence, les première et deuxième pièces d'accouplement sont cylindriques, de même que l'alésage du manchon décoratif amovible.Preferably, the first and second coupling parts are cylindrical, as is the bore of the removable decorative sleeve.

Selon un mode de réalisation particulière, la seconde pièce d'accouplement comprend une partie cylindrique creuse fendue selon au moins une génératrice pour créer une élasticité dans le sens transversal et la première pièce d'accouplement comprend une partie cylindrique pleine fendue selon un plan longitudinal.According to a particular embodiment, the second coupling part comprises a hollow cylindrical part split along at least one generatrix to create elasticity in the transverse direction and the first coupling part comprises a solid cylindrical part split along a longitudinal plane.

Les moyens d'arrêt formés sur la première pièce d'accouplement peuvent être constitués par une gorge coopérant avec un épaulement réalisé sur la deuxième pièce d'accouplement.The stop means formed on the first coupling part may consist of a groove cooperating with a shoulder produced on the second coupling part.

Selon une caractéristique particulière, chacune des première et deuxième pièces d'accouplement comprend un anneau de butée servant de retenue pour le manchon amovible.According to a particular characteristic, each of the first and second coupling parts comprises a stop ring serving as a retainer for the removable sleeve.

Dans un premier mode de réalisation de l'invention, le manchon présente un alésage ayant une section de même forme et sensiblement de mêmes dimensions que celles de la seconde pièce d'accouplement.In a first embodiment of the invention, the sleeve has a bore having a section of the same shape and substantially the same dimensions as those of the second coupling part.

Dans un second mode de réalisation possible, le manchon présente un alésage ayant une section plus grande que celle de la seconde pièce d'accouplement et une forme différente de cette dernière, de façon à ne porter sur la pièce femelle que selon un nombre limité de génératrices.In a second possible embodiment, the sleeve has a bore having a section larger than that of the second coupling part and a shape different from the latter, so as to bear on the female part only in a limited number of generators.

La présente invention se prête à la réalisation d'un fermoir multiple comprenant plusieurs paires de pièces d'accouplement mâle et femelle et un manchon unique présentant plusieurs alésages destinés à recevoir chacun une pièce d'accouplement femelle.The present invention lends itself to the production of a multiple clasp comprising several pairs of male and female coupling parts and a single sleeve having several bores each intended to receive a female coupling part.

L'invention est applicable à tous les articles de mode tels que notamment colliers, bracelets, bijoux, sacs à main ou ceintures.The invention is applicable to all fashion items such as necklaces, bracelets, jewelry, handbags or belts.

D'autres caractéristiques et avantages de l'invention ressortiront de la description suivante de modes particuliers de réalisation, donnés à titre d'exemple, en référence aux dessins annexés, sur lesquels :

  • - la figure 1 est une vue éclatée d'un fermoir selon l'invention,
  • - les figures 2 et 3 sont des vues de face et de droite de la pièce d'accouplement femelle du fermoir de la figure 1,
  • - les figures 4, 5 et 6 sont des vues respectivement de face, en coupe selon la ligne V-V de la figure 4 et de droite de la pièce d'accouplement mâle du fermoir de la figure 1,

  • - les figures 11 et 12 représentent en vue de face deux autres modes de réalisation de fermoir.
Other characteristics and advantages of the invention will emerge from the following description of particular embodiments, given by way of example, with reference to the appended drawings, in which:
  • FIG. 1 is an exploded view of a clasp according to the invention,
  • FIGS. 2 and 3 are front and right views of the female coupling part of the clasp of FIG. 1,
  • FIGS. 4, 5 and 6 are respectively front views, in section along the line VV in FIG. 4 and on the right of the male coupling piece of the clasp in FIG. 1,
  • FIGS. 7 to 10 show in section along a plane perpendicular to the axis of the clasp, various alternative embodiments of the coupling parts and of the removable sleeve of the clasp according to the invention, and
  • - Figures 11 and 12 show a front view of two other embodiments of the clasp.

On voit sur la figure 1, en position éclatée, un exemple de fermoir selon l'invention qui comprend une première pièce mâle d'accouplement 10, un manchon décoratif amovible 30 présentant un alésage 32 de section a et une surface décorative externe 31, et une seconde pièce femelle d'accouplement 20.FIG. 1 shows, in the exploded position, an example of a clasp according to the invention which comprises a first male coupling part 10, a removable decorative sleeve 30 having a bore 32 of section a and an external decorative surface 31, and a second female coupling part 20.

Le manchon 30 présente un alésage 32 de forme cylindrique et une surface extérieure 31 qui peut présenter les formes et aspects les plus variés. En particulier des éléments décoratifs, tels que par exemple des pierres précieuses ou semi- précieuses, peuvent être rapportés sur la surface externe 31 du manchon 30.The sleeve 30 has a bore 32 of cylindrical shape and an outer surface 31 which can have the most varied shapes and aspects. In particular decorative elements, such as for example precious or semi-precious stones, can be added to the external surface 31 of the sleeve 30.

Le manchon 30 peut être réalisé en métal commun ou précieux et être fabriqué par exemple par un estampage-découpage-décolletage ou à partir de métal fondu ou par électroérosion. Toutefois, le manchon 30 peut aussi être réalisé en toute autre matière naturelle ou synthétique permettant de donner au manchon un aspect décoratif ou de rapporter sur la surface externe 31 du manchon des éléments décoratifs. D'une manière générale, toutefois, le manchon doit être réalisé en une matière rigide permettant de réaliser un alésage 32 ne présentant pratiquement pas d'élasticité dans le sens transversal.The sleeve 30 can be made of common or precious metal and be produced for example by stamping-cutting-cutting or from molten metal or by electroerosion. However, the sleeve 30 can also be made of any other natural or synthetic material making it possible to give the sleeve a decorative appearance or to attach decorative elements to the external surface 31 of the sleeve. Generally, however, the sleeve must be made of a rigid material making it possible to produce a bore 32 having practically no elasticity in the transverse direction.

Le manchon 30 est prévu pour s'engager sur le corps cylindrique 21 de la pièce femelle d'accouplement 20 et venir en arrêt contre la butée d'arrêt 23 sur laquelle est rapporté un anneau 25 de raccordement à une extrémité de l'article à équiper du fermoir.The sleeve 30 is designed to engage on the cylindrical body 21 of the female coupling part 20 and come to a stop against the stop stop 23 to which a connection ring 25 is attached at one end of the article to fitted with a clasp.

Le corps cylindrique 21 de la pièce femelle 20 présente lui-même une élasticité dans le sens transversal afin de permettre une insertion aisée de ce corps 21 dans t'alésage 32 du manchon 30. La pièce mâle d'accouplement 10, réalisée sous forme de pince, présente elle-même un corps cylindrique 11 présentant une élasticité dans le sens transversal afin de permettre une insertion de ce corps 11 à l'intérieur du corps cylindrique creux 21 de la pièce femelle 20 entourée du manchon amovible 30. Une butée 13 formée à l'extrémité du corps cylindrique 11 non engagée dans le corps creux 21 permet d'immobiliser totalement le manchon 30 qui est emprisonné entre les butées 13 et 23 des deux pièces d'accouplement 10, 20. En position fermée du fermoir, grâce à l'élasticité du corps 11 de la pièce mâle 10 formant pince, des moyens de verrouillage 14 formés sur la pièce mâle 10 au voisinage de la butée 13 coopèrent avec des moyens de verrouillage complémentaires 24 réalisés à l'extrémité libre du corps 21 de la pièce femelle 20 pour empêcher toute séparation des divers éléments constitutifs du fermoir.The cylindrical body 21 of the female part 20 itself has elasticity in the transverse direction in order to allow easy insertion of this body 21 into the bore 32 of the sleeve 30. The male coupling part 10, produced in the form of clamp, itself has a cylindrical body 11 having an elasticity in the transverse direction in order to allow insertion of this body 11 inside the hollow cylindrical body 21 of the female part 20 surrounded by the removable sleeve 30. A stop 13 formed at the end of the cylindrical body 11 not engaged in the hollow body 21 makes it possible to completely immobilize the sleeve 30 which is trapped between the stops 13 and 23 of the two coupling parts 10, 20. In the closed position of the clasp, thanks to the elasticity of the body 11 of the male part 10 forming a clamp, locking means 14 formed on the male part 10 in the vicinity of the stop 13 cooperate with complementary locking means 24 produced at the free end of the body s 21 of the female part 20 to prevent any separation of the various components of the clasp.

Si l'on considère plus particulièrement les figures 2 et 3, on voit une pièce femelle 20 présentant un corps cylindrique creux 21 muni selon au moins une génératrice, et de préférence selon au moins deux génératrices diamétralement opposées situées dans un même plan axial, d'une fente 22 de longueur inférieure à la longueur totale 1 du corps 21, et de faible largeur, par exemple de quelques dixièmes de millimètres. Cette fente longitudinale médiane, provoquant un écartement de quelques centièmes de millimètre, permet de faire ressort et d'immobiliser le manchon 30 lors de son enfilage sur le corps cylindrique 21 de la pièce femelle 20. La pièce femelle 20 comporte, à l'extrémité non fendue de son corps allongé 21 une butée 23, dont la forme peut être très variée, mais est par exemple réalisée sous la forme d'un anneau ou disque concentrique au corps 21, et de section b supérieure à la section a de l'alésage du manchon 30. Un anneau 25, muni d'une ouverture centrale 26, est rapporté sur la butée 23 afin de permettre la fixation par exemple de l'extrémité d'un collier, non représenté.If we consider more particularly Figures 2 and 3, we see a female part 20 having a hollow cylindrical body 21 provided along at least one generator, and preferably according to at least two diametrically opposed generators located in the same axial plane, d 'A slot 22 of length less than the total length 1 of the body 21, and of small width, for example a few tenths of a millimeter. This median longitudinal slot, causing a spacing of a few hundredths of a millimeter, makes it possible to bring out and immobilize the sleeve 30 when it is threaded on the cylindrical body 21 of the female part 20. The female part 20 comprises, at the end not split from its elongated body 21 a stop 23, the shape of which can be very varied, but is for example produced in the form of a ring or disc concentric with the body 21, and of section b greater than section a of the bore of the sleeve 30. A ring 25, provided with a central opening 26, is attached to the stop 23 in order to allow the fixing, for example, of the end of a collar, not shown.

On notera que le diamètre c du corps cylindrique 21 doit rester pratiquement constant sur toute la longueur 1 du corps 21 et ne présenter qu'un écart de l'ordre de quelques centièmes de millimètre à son extrémité fendue. A la partie non fendue du corps 21, le diamètre c du corps cylindrique correspond pour l'essentiel au diamètre c du corps cylindrique correspond pour l'essentiel au diamètre a de l'alésage 32 du manchon 30 et n'est inférieur à celui-ci que de la valeur du jeu nécessaire à la circulation du manchon 30 sur le corps 21 de la pièce femelle 20. Avantageusement, la pièce femelle 21 présente à son extrémité libre fendue un chanfrein extérieur 27 qui facilite l'introduction du manchon 30.It will be noted that the diameter c of the cylindrical body 21 must remain practically constant over the entire length 1 of the body 21 and only present a difference of the order of a few hundredths of a millimeter at its slotted end. At the unsplit part of the body 21, the diameter c of the cylindrical body corresponds essentially to the diameter c of the cylindrical body corresponds essentially to the diameter a of the bore 32 of the sleeve 30 and is not less than that. the value of the clearance necessary for the circulation of the sleeve 30 on the body 21 of the female part 20. Advantageously, the female part 21 has at its split free end an external chamfer 27 which facilitates the introduction of the sleeve 30.

A l'intérieur du corps cylindrique creux 21 de la pièce femelle 20, du côté de l'extrémité libre fendue, un épaulement ou anneau d'arrêt 24 est réalisé sur le pourtour interne du corps cylindrique 21 pour permettre un verrouillage dans une gorge correspondante 14 réalisée sur la pièce mâle d'accouplement 10. La pièce femelle d'accouplement 20 peut être réalisée en métal ou toute autre matière permettant de conférer au corps 21 une rigidité dans le sens axial et une élasticité dans le sens radial, soit par la nature même du matériau, soit par la réalisation d'entailles longitudinales 22.Inside the hollow cylindrical body 21 of the female part 20, on the side of the slotted free end, a shoulder or stop ring 24 is formed on the internal periphery of the cylindrical body 21 to allow locking in a corresponding groove 14 produced on the male coupling part 10. The female coupling part 20 can be made of metal or any other material making it possible to give the body 21 rigidity in the axial direction and elasticity in the radial direction, either by very nature of the material, either by making longitudinal notches 22.

Les figures 4 à 6 permettent de voir de façon plus détaillée la configuration d'un exemple de pièce mâle d'accouplement 10 appariée à la pièce 20 des figures 2 et 3. Selon ce mode de réalisation, la pièce mâle 10 comprend un corps cylindrique 11 constitué par un fil demi-jonc replié sur lui-même et rattaché à son extrémité arrière à une butée 13 présentant une section de diamètre f supérieure au diamètre a de l'alésage 32 du manchon 30. La butée 13 est en réalité constituée en deux parties 13a, 13b disposées dans un même plan radial par rapport au corps 11 et rattachées respectivement à la partie supérieure 11a du corps 11 et à la partie inférieure 11b du corps 11, espacées par une fente 12 présentant une faible largeur, de l'ordre de quelques dixièmes de millimètre.FIGS. 4 to 6 allow a more detailed view of the configuration of an example of a male coupling part 10 paired with the part 20 of FIGS. 2 and 3. According to this embodiment, the male part 10 comprises a cylindrical body 11 constituted by a half-rod wire folded back on itself and attached at its rear end to a stop 13 having a section of diameter f greater than the diameter a of the bore 32 of the sleeve 30. The stop 13 is in reality made of two parts 13a, 13b arranged in the same radial plane with respect to the body 11 and attached respectively to the upper part 11a of the body 11 and to the lower part 11b of the body 11, spaced apart by a slot 12 having a small width, of the order of a few tenths of a millimeter.

Un anneau 15 muni d'une ouverture 16 est fixé sur l'une des demi-butées 13a, 13b, par exemple sur la demi-butée supérieure 13a, et sert à la fixation d'une extrémité de l'article à équiper d'un fermoir. Une pièce 17 en forme de languette peut également être fixée à la demi-butée inférieure 13b afin de faciliter la manipulation de la pièce mâle 10 en forme de pince. Une pression simultanée sur l'anneau 15 et sur la languette 17 permet de serrer la pince et rapprocher les parties supérieure et inférieure 11a, 11b du corps 11, refermant ainsi au moins partiellement la fente 12. On notera toutefois que la languette 17 n'est pas indispensable et que la pièce 10 peut être saisie et resserrée par les deux demi-butées 13a, 13b.A ring 15 provided with an opening 16 is fixed on one of the half-stops 13a, 13b, for example on the upper half-stop 13a, and is used for fixing one end of the article to be fitted with a clasp. A piece 17 in the form of a tongue can also be fixed to the lower half-stop 13b in order to facilitate the manipulation of the male piece 10 in the form of a clamp. Simultaneous pressure on the ring 15 and on the tongue 17 makes it possible to tighten the clamp and bring the upper and lower parts 11a, 11b closer to the body 11, thus at least partially closing the slot 12. It will however be noted that the tongue 17 does not is not essential and that the part 10 can be grasped and tightened by the two half-stops 13a, 13b.

Une gorge annulaire 14 est ménagée sur le corps 11, à proximité immédiate de la butée 13, afin de constituer un élément de verrouillage coopérant avec l'anneau intérieur 24 de la pièce femelle 20. La section et la profondeur de la gorge 14 sont légèrement supérieures à celles de l'anneau d'arrêt 24 de la pièce 20. Des moyens de verrouillage complémentaires équivalents à l'association anneau d'arrêt 24, gorge 14 pourraient naturellement être substitués sur les pièces 10 et 20.An annular groove 14 is formed on the body 11, in the immediate vicinity of the stop 13, in order to constitute a locking element cooperating with the inner ring 24 of the female part 20. The section and the depth of the groove 14 are slightly greater than those of the stop ring 24 of the part 20. Additional locking means equivalent to the association of the stop ring 24, groove 14 could naturally be substituted on the parts 10 and 20.

Le diamètre e du corps cylindrique 11 est inférieur au diamètre intérieur d de l'anneau d'arrêt 24 de la pièce 20, de la valeur du jeu nécessaire à la circulation de la pièce 10 dans la pièce 20. Du fait de la présence de la fente 12 séparant les deux branches inférieure 11b et supérieure 11a de la pince 10, la pince 10 forme ressort et, lorsqu'aucune pression manuelle n'est exercée sur les deux demi-butées 13a, 13b ou des éléments de préhension solidaires de ces deux demi-butées, l'anneau d'arrêt 24 reste engagé de façon sûre dans la gorge 14, du fait que les deux parties 11 a et 11 b de la pince 10 ont tendance à s'écarter l'une de l'autre. Naturellement, la longueur t du corps cylindrique 11 est un peu inférieure à la longueur I du corps cylindrique 21. La pièce d'accouplement 10, comme la pièce 20, peut être métallique ou réalisée en un autre matériau approprié permettant par sa nature ou par la configuration du corps cylindrique 11, de conférer à la pièce 10 une rigidité dans le sens axial et une élasticité dans le sens radial.The diameter e of the cylindrical body 11 is less than the internal diameter d of the stop ring 24 of the part 20, by the value of the clearance necessary for the circulation of the part 10 in the part 20. Due to the presence of the slot 12 separating the two lower 11b and upper 11a branches of the clamp 10, the clamp 10 forms a spring and, when no manual pressure is exerted on the two half-stops 13a, 13b or gripping elements integral with these two half stops, the stop ring 24 remains securely engaged in the groove 14, because the two parts 11 a and 11 b of the clamp 10 tend to move away from one another . Naturally, the length t of the cylindrical body 11 is a little less than the length I of the cylindrical body 21. The coupling piece 10, like the piece 20, can be metallic or made of another suitable material allowing by its nature or by the configuration of the cylindrical body 11, to give the piece 10 a rigidity in the axial direction and an elasticity in the radial direction.

Dans le mode de réalisation des figures 1 à 6, on a représenté un alésage 32 de manchon, un corps 21 de pièce femelle 20 et un corps 11 de la pièce mâle 10 qui sont cylindriques et de section circulaire. Diverses autres configurations peuvent être envisagées pour la section des éléments cylindriques constitués par l'alésage pour la section des éléments cylindriques constitués par l'alésage 32, le corps 21 et le corps 11, par exemple des formes carrées, ovales ou rectangulaires. De plus, si les sections des corps cylindriques 11 et 21 des pièces 10 et 20 sont de préférence de même forme, l'alésage 32 du manchon 30 peut lui-même présenter une forme différente de celle du corps 21 de la pièce femelle 20 et ne porter sur celle-ci que selon un nombre limité de génératrices, par exemple trois ou quatre génératrices.In the embodiment of Figures 1 to 6, there is shown a sleeve bore 32, a body 21 of the female part 20 and a body 11 of the male part 10 which are cylindrical and of circular section. Various other configurations can be envisaged for the section of the cylindrical elements formed by the bore for the section of the cylindrical elements formed by the bore 32, the body 21 and the body 11, for example square, oval or rectangular shapes. In addition, if the sections of the cylindrical bodies 11 and 21 of the parts 10 and 20 are preferably of the same shape, the bore 32 of the sleeve 30 may itself have a shape different from that of the body 21 of the female part 20 and wear it only on a limited number of generators, for example three or four generators.

On a représenté sur les figures 7 à 10 quelques exemples de configurations différentes de celle des figures 1 à 6, selon lesquelles la section de l'alésage 32 ou des corps cylindriques 11, 21 n'est pas circulaire.FIGS. 7 to 10 show some examples of configurations different from that of FIGS. 1 to 6, according to which the section of the bore 32 or of the cylindrical bodies 11, 21 is not circular.

Les figures 7 et 8 représentent des fermoirs dans lesquels les pièces d'accouplement 10, 20 sont conformes au mode de réalisation des figures 1 à 6, c'est-à-dire présentent des corps 11, 21 de section circulaire, mais le manchon 130, 230 comporte un alésage 132, 232 non circulaire qui présente une section supérieure à celle du corps 21 de la pièce femelle 20 et ne porte sur cette dernière que le long de trois ou quatre génératrices 133, 233 respectivement. La forme du contour extérieur 131, 231 des manchons 130, 230 peut elle-même être quelconque.Figures 7 and 8 show clasps in which the coupling parts 10, 20 conform to the embodiment of Figures 1 to 6, that is to say have bodies 11, 21 of circular section, but the sleeve 130, 230 has a non-circular bore 132, 232 which has a cross section greater than that of the body 21 of the female part 20 and relates to the latter only along three or four generators 133, 233 respectively. The shape of the outer contour 131, 231 of the sleeves 130, 230 can itself be arbitrary.

La figure 9 montre un fermoir dans lequel le manchon 30 est conforme au mode de réalisation de la figure 1 et comporte un alésage 32 de section circulaire. Toutefois, les corps cylindriques 111, 121 des pièces mâle 110 et femelle 120 appariées, fendus selon des ouvertures 112, 122 présentent eux-mêmes une section carrée et le corps 121 de la pièce femelle 120 porte sur l'alésage 32 selon quatre génératrices 33.Figure 9 shows a clasp in which the sleeve 30 conforms to the embodiment of Figure 1 and has a bore 32 of circular section. However, the cylindrical bodies 111, 121 of the paired male 110 and female parts 120, split through openings 112, 122 themselves have a square section and the body 121 of the female part 120 bears on the bore 32 according to four generatrices 33 .

La figure 10 représente encore une autre forme possible de fermoir avec un manchon décoratif 330 comportant un alésage 332 de section ovale coopérant avec un corps 221 de pièce femelle d'accouplement 220 dont la section est inscrite dans un rectangle et porte dans l'alésage 332 le long de quatre génératrices 333. Dans le mode de réalisation de la figure 10, les pièces d'accouplement 210 et 220 comportent un corps 211, 221 dont la section a la forme d'un U. Ainsi, le corps 211 de la pièce mâle 210 comprend une partie plane formant fond raccordée à deux rebords longitudinaux 218 présentant une certaine flexibilité dans le sens transversal. Le corps 211 est lui-même engagé dans le corps 221 de la pièce femelle 220 composé de façon similaire avec une partie plane de fond et deux rebords longitudinaux 228 enserrant les rebords longitudinaux 218 et pouvant présenter des parties recourbées 227 flexibles repliées vers l'intérieur en coiffant les rebords longitudinaux 218 du corps 211. Ce mode de réalisation des pièces d'accouplement 210, 220 pourrait naturellement être adapté également à des manchons 330 ayant des alésages 332 de forme différente, par exemple rectangulaire.FIG. 10 shows yet another possible form of clasp with a decorative sleeve 330 comprising a bore 332 of oval section cooperating with a body 221 of female coupling part 220 the section of which is inscribed in a rectangle and carries in the bore 332 along four generators 333. In the embodiment of FIG. 10, the coupling parts 210 and 220 comprise a body 211, 221 whose section has the shape of a U. Thus, the body 211 of the part male 210 includes a flat bottom portion connected to two longitudinal edges 218 having a certain flexibility in the transverse direction. The body 211 is itself engaged in the body 221 of the female part 220 similarly composed with a flat bottom part and two longitudinal edges 228 enclosing the longitudinal edges 218 and may have curved portions 227 flexible folded inwards by covering the longitudinal edges 218 of the body 211. This embodiment of the coupling parts 210, 220 could naturally also be adapted to sleeves 330 having bores 332 of different shape, for example rectangular.

La présente invention qui vise essentiellement à permettre de réaliser des fermoirs d'aspects variés à partir d'un même type de mécanisme de fermeture de base standard se prête à de nombreuses variantes de réalisation. Ainsi, le manchon 30 prévu pour s'enfiler sur la pièce d'accouplement 20 peut être constitué par plusieurs tronçons de manchon coaxiaux alignés disposés successivement sur le corps cylindrique 21.The present invention which essentially aims at making it possible to make clasps of various aspects from the same type of standard basic closing mechanism lends itself to many variant embodiments. Thus, the sleeve 30 provided for threading on the coupling part 20 can be constituted by several sections of aligned coaxial sleeve successively arranged on the cylindrical body 21.

La figure 11 montre ainsi un autre mode de réalisation dans lequel un fermoir comprend un manchon en plusieurs parties 531, 532, 533, de formes non identiques, l'une d'entre elles pouvant supporter un pendentif 541, recevant une paire de pièces complémentaires 10, 20 semblables par exemple aux pièces des figures 1 à 6, destinée à assurer la fermeture par exemple d'une rangée de perles de collier. Comme on peut le voir sur la figure 11, une pièce du manchon peut déborder au-delà des butées 13, 23 des pièces 10. 20 qui se trouvent alors encastrées dans un espace 534 recouvert par la surface extérieure 531.FIG. 11 thus shows another embodiment in which a clasp comprises a sleeve in several parts 531, 532, 533, of non-identical shapes, one of them being able to support a pendant 541, receiving a pair of complementary parts 10, 20 similar for example to the parts of Figures 1 to 6, intended to ensure the closure for example of a row of necklace beads. As can be seen in FIG. 11, a part of the sleeve can project beyond the stops 13, 23 of the parts 10. 20 which are then embedded in a space 534 covered by the external surface 531.

La figure 12 montre encore un autre mode de réalisation dans lequel un même fermoir comprend un manchon unique 430 muni de plusieurs alésages 432 recevant chacun une paire de pièces d'accouplement complémentaires 10, 20 semblables par exemple aux pièces des figures 1 à 6, chaque paire étant destinée à assurer la fermeture par exemple d'une rangée de perles de collier. Comme on peut le voir sur la figure 12, le manchon peut déborder au-delà des butées 13, 23 des pièces 10, 20 qui se trouvent alors encastrées dans un espace 434 recouvert par la surface extérieure 431 du manchon 430.FIG. 12 shows yet another embodiment in which the same clasp comprises a single sleeve 430 provided with several bores 432 each receiving a pair of complementary coupling parts 10, 20 similar for example to the parts of FIGS. 1 to 6, each pair being intended to ensure the closure for example of a row of necklace beads. As can be seen in FIG. 12, the sleeve can project beyond the stops 13, 23 of the parts 10, 20 which are then embedded in a space 434 covered by the external surface 431 of the sleeve 430.
