The latter includes catching means comprising, on the one hand, a retention device (22) and, on the other hand, catching devices (24) and locking means (26). The retention device (22) advantageously includes a bead (28) integral with the post (16) and the catching devices (24) of the claws (30) integral with elastic strips (34) which join them to the female element (10). These strips (34) stand instead of locking means (26). These locking means (26), which are elastically deformable, lock the devices (22, 24) beyond a limit value of axial traction exerted on the elements (10, 12). <IMAGE>

Description

La présente invention se rapporte aux charnières notamment pour bracelet ou pour montre-bracelet. Elle a pour objet une charnière du type comprenant un organe femelle muni d'un tube, un organe mâle muni d'un tenon et articulé dans l'organe femelle, autour d'un axe tenant lieu d'axe d'articulation de la charnière, et un verrou axial.The present invention relates to hinges, in particular for a bracelet or a wristwatch. It relates to a hinge of the type comprising a female member provided with a tube, a male member provided with a lug and articulated in the female member, around an axis serving as a hinge axis. , and an axial lock.

Une telle charnière est connue par exemple par le brevet CH 598 782 qui décrit un bracelet à maillons articulés au moyen de charnières de ce type. Dans ce brevet, chaque charnière comprend deux organes mâles, deux organes femelles et un verrou formé d'un ressort qui est en appui contre un bras reliant l'un de ces organes au corps du maillon. Le démontage de tels bracelets nécessite l'utilisation d'objets permettant le déplacement du ressort tenant lieu de verrou, ce qui peut poser des problèmes, notamment lors de la vente, dans le cas où le vendeur n'est pas un horloger.Such a hinge is known for example from patent CH 598 782 which describes a bracelet with articulated links by means of hinges of this type. In this patent, each hinge comprises two male members, two female members and a latch formed by a spring which bears against an arm connecting one of these members to the body of the link. The disassembly of such bracelets requires the use of objects allowing the movement of the spring in lieu of a lock, which can cause problems, especially during the sale, in the case where the seller is not a watchmaker.

Le but de la présente invention est de réaliser une charnière à verrou, dont le démontage ne nécessite pas d'outil particulier.The object of the present invention is to produce a lock hinge, the disassembly of which does not require any particular tool.

Ce but est atteint grâce au fait que le verrou comporte des moyens d'accrochage faits de deux parties respectivement solidaires des organes mâle et femelle et des moyens de verrouillage déformables élastiquement, pour verrouiller les deux parties en-deçà d'une valeur limite de traction axiale exercée sur les organes.This object is achieved thanks to the fact that the bolt comprises hooking means made of two parts respectively secured to the male and female members and elastically deformable locking means, for locking the two parts below a traction limit value. axial exerted on the organs.

Grâce à ces caractéristiques, la mise de longueur ou le changement du bracelet peut se faire par un simple mouvement de cisaillement sur deux maillons voisins ou sur le bracelet et la boite.Thanks to these characteristics, the length setting or the change of the bracelet can be done by a simple shearing movement on two neighboring links or on the bracelet and the case.

On connaît certes par le document FR-A-2 300 197 des charnières comportant des moyens de verrouillage déformables élastiquement pour verrouiller les organes mâle et femelle. Ces charnières, en plastique, non déverrouillables, sont destinées à être utilisées dans des meubles soumis à des variations de température, à cause de la flexibilité du plastique. Bien que très voisine, par sa structure, de la charnière selon l'invention, la charnière décrite dans FR-A-2 300 197 ne pourrait sans autre être appliquée à la fabrication d'un bracelet. De plus, même adaptée, elle ne pourrait résoudre le problème de la mise à la longueur ou le changement du bracelet, puisqu'elle est indémontable.Document FR-A-2 300 197 is certainly known for hinges comprising elastically deformable locking means for locking the male and female members. These non-unlockable plastic hinges are intended for use in furniture subject to temperature variations due to the flexibility of the plastic. Although very similar, by its structure, to the hinge according to the invention, the hinge described in FR-A-2 300 197 could not without other application be applied to the manufacture of a bracelet. In addition, even adapted, it could not resolve the problem of setting the length or changing the bracelet, since it is not removable.

L'invention sera mieux comprise à la lecture de la description qui va suivre, faite en référence aux dessins dans lesquels:

  • - les figures 1, 2 et 3 représentent respectivement en perspective éclatée et en coupes axiale et radiale, une charnière selon un mode préféré de réalisation de l'invention;
  • - les figures 4 à 7 représentent, par des coupes respectivement axiale et radiale, deux autres modes de réalisation de l'invention; et
  • - la figure 8 est une vue en perspective d'une montre munie d'un bracelet à maillons reliés entre eux au moyen de charnières selon l'invention.
The invention will be better understood on reading the description which follows, made with reference to the drawings in which:
  • - Figures 1, 2 and 3 show respectively in exploded perspective and in axial and radial sections, a hinge according to a preferred embodiment of the invention;
  • - Figures 4 to 7 show, by axial and radial sections, respectively, two other embodiments of the invention; and
  • - Figure 8 is a perspective view of a watch provided with a link bracelet linked together by means of hinges according to the invention.

Ainsi qu'on peut le voir sur les figures 1, 2 et 3, la charnière selon l'invention comporte un organe femelle 10 muni d'un tube 12, un organe mâle 14 muni d'un corps 15 et d'un tenon 16 articulé dans l'organe femelle 10 autour d'un axe 18 tenant lieu d'axe d'articulation de la charnière, et un verrou axial 20. Ce verrou comporte des moyens d'accrochage comprenant d'une part un élément de retenue 22, d'autre part quatre éléments d'accrochage 24, et des moyens de verrouillage 26 déformables élastiquement, pour verrouiller les éléments en-deçà d'une valeur limite de traction axiale exercée sur les organes 10 et 14. Le premier élément 22 est formé par un bourrelet 28 qui dépasse radialement vers l'extérieur d'une portion axiale 29 de l'organe mâle 14, cette dernière étant solidaire du tenon 16. Plus précisément, ce bourrelet est formé par une portion en forme de rotule dont le centre est situé sur l'axe 18 et solidaire de la portion 29. Les seconds éléments 24 comportent chacun une griffe 30 mobile élastiquement et coopérant avec le bourrelet 28 pour former les moyens d'accrochage. Ces griffes 30 s'étendent radialement vers l'intérieur et sont chacune reliées à l'organe femelle, et plus précisément à un bouchon 32 obturant l'une des extrémités du tube 12, par une lamelle élastique 34 s'étendant axialement et formant les moyens de verrouillage 26. En d'autres termes, les moyens de verrouillage 26 sont solidaires des seconds éléments 24 et les relient à l'organe femelle 10. Les éléments 22 et 24 des moyens d'accrochage et les moyens de verrouillage 26 sont agencés de manière que les griffes 30 enserrent le bourrelet 28, les lamelles élastiques 34 exerçant une force qui tend à s'opposer à l'écartement des griffes 30 dans le sens radial. Si l'on trace une tangente t au bourrelet 28, et passant par le lieu de contact des griffes 30, cette tangente forme un angle a avec l'axe 18, avantageusement compris entre 30 et 70° (fig. 2). Grâce à cette configuration, l'application d'une traction axiale sur les organes femelle 10 et mâle 14 induit une force tendant à écarter les griffes 30. Lorsque cette force est supérieure aux forces dues à l'armage des lamelles élastiques qui tendent à s'opposer à leur écartement, les griffes 30 s'écartent, laissant passer le bourrelet 28, ce qui permet le démontage de la charnière. Ainsi, pour démonter cette charnière, il suffit d'exercer une force axiale suffisante pour écarter les griffes 30 et libérer ainsi le bourrelet 28. Les griffes 30, le bourrelet 28 et les lamelles élastiques 34 sont dimensionnés de manière que cette force soit comprise entre 80 g et 1 kg, typiquement de 200 g.As can be seen in Figures 1, 2 and 3, the hinge according to the invention comprises a female member 10 provided with a tube 12, a male member 14 provided with a body 15 and a stud 16 articulated in the female member 10 around an axis 18 acting as an axis of articulation of the hinge, and an axial lock 20. This lock comprises attachment means comprising on the one hand a retaining element 22, on the other hand four hooking elements 24, and locking means 26 elastically deformable, for locking the elements below a limit value of axial traction exerted on the members 10 and 14. The first element 22 is formed by a bead 28 which protrudes radially outward from an axial portion 29 of the male member 14, the latter being integral with the stud 16. More specifically, this bead is formed by a ball-shaped portion whose center is located on the axis 18 and integral with the portion 29. The second elements 24 each have a claw 30 movable elastically and cooperating with the bead 28 to form the attachment means. These claws 30 extend radially inwards and are each connected to the female member, and more precisely to a plug 32 closing one of the ends of the tube 12, by an elastic strip 34 extending axially and forming the locking means 26. In other words, the locking means 26 are integral with the second elements 24 and connect them to the female member 10. The elements 22 and 24 of the attachment means and the locking means 26 are arranged so that the claws 30 enclose the bead 28, the elastic strips 34 exerting a force which tends to oppose the spacing of the claws 30 in the radial direction. If a tangent t is drawn at the bead 28, and passing through the place of contact of the claws 30, this tangent forms an angle a with the axis 18, advantageously between 30 and 70 ° (fig. 2). Thanks to this configuration, the application of axial traction on the female 10 and male 14 members induces a force tending to spread the claws 30. When this force is greater than the forces due to the winding of the elastic lamellae which tend to s 'opposing their spacing, the claws 30 move apart, letting pass the bead 28, which allows the disassembly of the hinge. Thus, to disassemble this hinge, it suffices to exert an axial force sufficient to spread the claws 30 and thus release the bead 28. The claws 30, the bead 28 and the elastic strips 34 are dimensioned so that this force is between 80 g and 1 kg, typically 200 g.

Pour réassembler les organes femelle 10 et mâle 14, il suffit d'introduire le tenon 16 dans le trou du tube 12 et d'appuyer pour que le bourrelet 28 écarte les griffes 30 et vienne de nouveau s'accrocher derrière elles.To reassemble the female 10 and male 14 organs, it suffices to introduce the tenon 16 into the hole of the tube 12 and to press so that the bead 28 spreads the claws 30 and comes again to hang behind them.

La charnière sera d'autant plus difficile à démonter que la force des lamelles élastiques 34 est grande et que l'angle a que forme l'axe 18 et la tangente t est grand.The hinge will be all the more difficult to disassemble the greater the force of the elastic strips 34 and the greater the angle α formed by the axis 18 and the tangent t.

Le mode de réalisation des figures 4 et 5 diffère de celui des figures 1, 2 et 3 du fait que le deuxième élément 24 des moyens d'accrochage et les moyens de verrouillage 26 sont formés ensemble d'une bague 36 comportant une fente radiale 38 et positionnée axialement dans une gorge radiale 40 définie dans l'organe femelle 10 par le bouchon 32 et une portée 12a que comporte le tube 12. Plus précisément l'élément 24 est formé par le bord intérieur de la bague 36. Par contre, l'organe mâle 14 et le premier élément 22 sont les mêmes que ceux du mode de réalisation représenté aux figures 1 et 2. Grâce au fait que la bague est fendue, elle est ainsi rendue élastiquement déformable, ce qui lui permet de tenir lieu de moyen de verrouillage 26.The embodiment of Figures 4 and 5 differs from that of Figures 1, 2 and 3 in that the second element 24 of the hooking means and the locking means 26 are formed together of a ring 36 having a radial slot 38 and positioned axially in a radial groove 40 defined in the female member 10 by the plug 32 and a bearing 12a that the tube 12 comprises. More precisely, the element 24 is formed by the inner edge of the ring 36. On the other hand, the 'male member 14 and the first element 22 are the same as those of the embodiment shown in Figures 1 and 2. Thanks to the fact that the ring is split, it is thus made elastically deformable, which allows it to act as a means lock 26.

Afin d'augmenter l'élasticité de la bague, celle-ci peut avoir une forme en trèfle, percée d'un trou triangulaire plutôt que d'être annulaire.In order to increase the elasticity of the ring, it can have a clover shape, pierced with a triangular hole rather than being annular.

Dans ce mode de réalisation, l'application d'une force axiale sur les organes femelle 10 et mâle 14 provoque l'écartement de la bague 36 qui permet le passage du bourrelet 28 dans un sens ou dans l'autre, selon qu'il s'agisse d'une force de traction ou de compression.In this embodiment, the application of an axial force on the female 10 and male 14 members causes the spacing of the ring 36 which allows the passage of the bead 28 in one direction or the other, depending on whether it be a tensile or compressive force.

Ainsi, dans les deux modes de réalisation décrits, l'élément de retenue 22 est solidaire de l'organe mâle 14, tandis que les éléments d'accrochage 24 ainsi que les moyens de verrouillage 26 sont solidaires de l'organe femelle 10.Thus, in the two embodiments described, the retaining element 22 is secured to the male member 14, while the latching elements 24 as well as the locking means 26 are secured to the female member 10.

Au contraire, dans le mode de réalisation des figures 6 et 7, l'élément de retenue 22 est solidaire de l'organe femelle 10. Il est formé d'une bague rigide 41 bloquée axialement dans la gorge radiale 40 définie dans l'organe femelle 10 par le bouchon 32 et la portée 12a du tube 12. Les éléments d'accrochage 24, au nombre de quatre, sont formés par des griffes 42 qui s'étendent radialement vers l'extérieur. Les moyens de verrouillage 26 comportent quatre lamelles élastiques 44, s'étendant axialement et reliant les griffes 42 au tenon 16. Les flans des griffes 42 forment un angle aigu avec l'axe 18, de manière que, lorsqu'une force axiale est exercée sur les organes mâle et femelle, elle provoque un fléchissement des lamelles 44 qui tendent à faire se rapprocher les griffes 42 les unes des autres, jusqu'à pouvoir passer au travers du trou central de la bague 41.On the contrary, in the embodiment of Figures 6 and 7, the retaining element 22 is integral with the female member 10. It is formed of a rigid ring 41 locked axially in the radial groove 40 defined in the member female 10 by the plug 32 and the bearing 12a of the tube 12. The hooking elements 24, four in number, are formed by claws 42 which extend radially outwards. The locking means 26 comprise four elastic strips 44, extending axially and connecting the claws 42 to the stud 16. The blanks of the claws 42 form an acute angle with the axis 18, so that when an axial force is exerted on the male and female organs, it causes a deflection of the lamellae 44 which tend to cause the claws 42 to approach each other, until they can pass through the central hole of the ring 41.

Dans chacun des modes de réalisation représentés, les moyens d'accrochage comportent un élément de retenue, rigide, et un ou des éléments d'accrochage associés élastiquement à l'organe mâle ou femelle. Il est bien évident qu'en combinant l'organe mâle de la figure 6 avec l'organe femelle de la figure 4, il est possible d'obtenir un autre mode de réalisation dans lequel tous les éléments des moyens d'accrochage sont reliés élastiquement à leur organe respectif. Ce mode de faire permet de réduire le fléchissement des lamelles.In each of the embodiments shown, the attachment means comprise a rigid retaining element, and one or more attachment elements resiliently associated with the male or female member. It is quite obvious that by combining the male member of FIG. 6 with the female member of FIG. 4, it is possible to obtain another embodiment in which all the elements of the hooking means are elastically connected. to their respective bodies. This method of reducing the deflection of the lamellae.

Comme on peut le voir sur la figure 8, qui représente une montre comportant un bracelet 46 formé de maillons 46a à 46c et une boîte 48, ce type de charnière est particulièrement bien adapté pour la réalisation des articulations des maillons ainsi que pour la fixation du bracelet (notamment le maillon 46a) à la boîte 48 de la montre. Pour ce faire, chacun des maillons 46a à 46c porte sur l'une de ses tranches un organe femelle 10, soudé par la face extérieure du tube 12, et sur la tranche opposée un organe mâle 14, soudé par son corps 15, l'organe mâle de l'un des maillons étant articulé dans l'organe femelle du maillon voisin. De façon similaire, la boîte 48 porte un organe femelle 10 et un organe mâle 14.As can be seen in FIG. 8, which represents a watch comprising a bracelet 46 formed of links 46a to 46c and a case 48, this type of hinge is particularly well suited for making the joints of the links as well as for fixing the bracelet (in particular the link 46a) to the case 48 of the watch. To do this, each of the links 46a to 46c carries on one of its edges a female member 10, welded by the outside face of the tube 12, and on the opposite edge a male member 14, welded by its body 15, the the male member of one of the links being articulated in the female member of the neighboring link. Similarly, the box 48 carries a female member 10 and a male member 14.

Ce type d'attache du bracelet à la boîte est aussi utilisable avec un bracelet souple, en cuir par exemple, l'extrémité voisine de la boîte étant alors solidaire d'une pièce rigide portant l'un des organes de la charnière.This type of attachment of the bracelet to the box can also be used with a flexible bracelet, in leather for example, the neighboring end of the box then being secured to a rigid part carrying one of the members of the hinge.

Ainsi qu'il ressort de la description, la charnière telle que décrite et revendiquée permet de réaliser des bracelets dont le réglage de la longueur ne nécessite aucun moyen particulier, ou des montres dans lesquelles le changement du bracelet se fait de manière si aisée qu'elle permet au porteur même de l'effectuer à sa convenance, sans devoir faire appel à un spécialiste.As is apparent from the description, the hinge as described and claimed makes it possible to produce bracelets whose length adjustment does not require any particular means, or watches in which the change of the bracelet is done so easily that it allows the wearer himself to perform it at his convenience, without having to call in a specialist.
