Description détaillée des modes de réalisation préférésDetailed description of the preferred embodiments

Un fermoir pour bracelet va maintenant être décrit dans ce qui suit faisant référence conjointement aux figures 1, 2, 3 et 4.A bracelet clasp will now be described in the following with joint reference to the figures 1 , 2 , 3 And 4 .

Tel que représenté à la figure 1, le fermoir 1 comprend une lame 2 dont une première extrémité 20 est articulée sur une première extrémité 30 d'un premier brin 3 de bracelet via un arbre ou un axe traversant le brin, et dont la deuxième extrémité 21 de la lame 2 est libre. Encore selon une autre variante, la lame peut être clippée sur le brin via des pions solidaires de la lame, les pions étant formés en même temps que la lame lors de sa fabrication. On pourrait également imaginer que la lame et le premier brin 3 soient formés en même temps, avec des matériaux différents via un procédé de bi-injection, et forme une seule et même pièce.As shown in figure 1 , the clasp 1 comprises a blade 2 of which a first end 20 is articulated on a first end 30 of a first strand 3 of the bracelet via a shaft or an axis passing through the strand, and of which the second end 21 of the blade 2 is free . According to yet another variant, the blade can be clipped onto the strand via pins secured to the blade, the pins being formed at the same time as the blade during its manufacture. We could also imagine that the blade and the first strand 3 are formed at the same time, with different materials via a bi-injection process, and form a single part.

Comme on peut l'observer sur la figure 1, la première extrémité 20 peut présenter des découpes pour recevoir des portions cylindriques de l'extrémité 30 du premier brin de bracelet 3. Une telle construction permet d'avoir une articulation plus solide et plus rigide.As can be observed on the figure 1 , the first end 20 can have cutouts to receive cylindrical portions of the end 30 of the first strand of bracelet 3. Such a construction makes it possible to have a stronger and more rigid articulation.

Selon l'invention, ladite lame 2 comprend une découpe 5 de manière à former au moins un partie rigide 22, située à proximité de la première extrémité 20, et deux parties déformables opposées 23, 24 située à proximité de l'extrémité libre 21. La découpe peut prendre différentes formes, telle qu'une forme de T ou de Y par exemple, ou encore en forme de logo.According to the invention, said blade 2 comprises a cutout 5 so as to form at least one rigid part 22, located near the first end 20, and two opposite deformable parts 23, 24 located near the free end 21. The cutout can take different shapes, such as a T or Y shape for example, or even in the shape of a logo.

Comme on peut l'observer à la figure 1, les deux parties déformables comprennent chacune, sur la face orientée vers le brin de bracelet ou face inférieure, un pion 6 muni d'un crochet 6' agencé pour coopérer avec un trou 40 d'un deuxième brin 4 de bracelet et verrouiller le fermoir sur le deuxième brin 4. La hauteur du pion 6 est prévu légèrement supérieure à l'épaisseur du brin de bracelet de manière que le crochet 6' repose contre la surface du deuxième brin 4 lorsque le fermoir est en position verrouillée. De même, l'écartement entre les deux pions 6 est équivalent à la largeur du trou 40 du deuxième brin 4 de manière à ce que le fermoir procure un bon maintien et verrouillage une fois les crochets 6' en place. Les pions 6 et les crochets 6' forment ainsi un mécanisme de verrouillage arrangé pour maintenir accroché le fermoir au deuxième brin 4 lorsque la montre est portée.As we can observe in the figure 1 , the two deformable parts each comprise, on the face oriented towards the bracelet strand or lower face, a pin 6 provided with a hook 6' arranged to cooperate with a hole 40 of a second bracelet strand 4 and lock the clasp on the second strand 4. The height of the pin 6 is provided slightly greater than the thickness of the bracelet strand so that the hook 6' rests against the surface of the second strand 4 when the clasp is in the locked position. Likewise, the spacing between the two pins 6 is equivalent to the width of the hole 40 of the second strand 4 so that the clasp provides good support and locking once the 6' hooks are in place. The pins 6 and the hooks 6' thus form a locking mechanism arranged to keep the clasp attached to the second strand 4 when the watch is worn.

Avantageusement, la lame 2, les pions 6 et les crochets 6' forment un élément d'un seul tenant.Advantageously, the blade 2, the pins 6 and the hooks 6' form a single piece.

La lame 2 peut présenter des moyens de maintien supplémentaire du second brin de bracelet, tels qu'un téton 8 comme illustré sur la figure 2 de manière à offrir un point de maintien supplémentaire pour le second brin du bracelet. Avantageusement, ce téton 8 peut aussi servir d'aide pour la mise en place du fermoir sur le second brin de bracelet. Le téton 8 est disposé sur la face inférieure de la partie rigide de la lame 2 et est agencé pour coopérer avec un trou supplémentaire 41 du deuxième brin 4.The blade 2 may have additional means of holding the second bracelet strand, such as a nipple 8 as illustrated in the figure 2 so as to provide an additional holding point for the second strand of the bracelet. Advantageously, this nipple 8 can also serve as an aid for placing the clasp on the second strand of the bracelet. The pin 8 is arranged on the lower face of the rigid part of the blade 2 and is arranged to cooperate with an additional hole 41 of the second strand 4.

Le téton 8 sert ainsi de dispositif de sécurité empêchant le décrochage du second brin 4 de la lame 2 conduisant à un déverrouillage intempestif du fermoir lors d'un choc par exemple. Le téton 8 est avantageusement formé en même temps que la lame de manière à ce que l'ensemble forme un élément monobloc.The pin 8 thus serves as a safety device preventing the second strand 4 from coming loose from the blade 2 leading to untimely unlocking of the clasp during an impact for example. The pin 8 is advantageously formed at the same time as the blade so that the assembly forms a single piece element.

Les parties déformables 23 et 24 de la lame 2 présentent des bords usinés de manière à former des poussoirs 26 et faciliter la préhension du fermoir pour la déformation des parties déformables.The deformable parts 23 and 24 of the blade 2 have edges machined so as to form pushers 26 and facilitate gripping of the clasp for deformation of the deformable parts.

Selon un mode de réalisation de l'invention, la lame 2 comprend des bords saillants 25 agencés pour guider le second brin de bracelet 4, les bords saillants 25 étant positionnés à proximité de la première extrémité 20 de la lame 2, et orientés vers les brins de bracelet.According to one embodiment of the invention, the blade 2 comprises projecting edges 25 arranged to guide the second strand of bracelet 4, the projecting edges 25 being positioned near the first end 20 of the blade 2, and oriented towards the bracelet strands.

Selon un autre mode de réalisation de l'invention, illustré aux figure 3 et 4, la lame 2 comprend un passant 7 pour guider le second brin de bracelet 4, le passant 7 étant placé à proximité immédiate de la première extrémité 20 qui est articulée sur la première extrémité 30 du premier brin 3 de bracelet, le second brin de bracelet 4 passant sous le premier brin 3 puis au travers du passant 7.According to another embodiment of the invention, illustrated in Figure 3 And 4 , the blade 2 comprises a loop 7 to guide the second bracelet strand 4, the loop 7 being placed in the immediate vicinity of the first end 20 which is articulated on the first end 30 of the first bracelet strand 3, the second strand of bracelet 4 passing under the first strand 3 then through the loop 7.

La lame 2 du fermoir 1 est fabriquée dans un matériau choisi parmi : les matières plastiques, les métaux et les alliages métalliques, et les matériaux composites, via moulage, injection, usinage, étampage, impression 3D, ou une combinaison de ces méthodes. Il est également possible de réaliser une lame en bi-matière. La lame 2 peut par exemple être réalisée à partir de matière plastique et de métal, par exemple les parties déformables peuvent être réalisées en matière plastique et le reste en métal.The blade 2 of the clasp 1 is manufactured from a material chosen from: plastics, metals and metal alloys, and composite materials, via molding, injection, machining, stamping, 3D printing, or a combination of these methods. It is also possible to make a bi-material blade. The blade 2 can for example be made from plastic and metal, for example the deformable parts can be made from plastic and the rest from metal.

Encore selon un autre mode de réalisation (non visible sur les figures), le second brin de bracelet comprend des moyens de verrouillage agencés pour coopérer avec ladite lame.According to yet another embodiment (not visible in the figures), the second bracelet strand comprises locking means arranged to cooperate with said blade.

Nous allons à présent décrire la mise en place du fermoir et sa libération du deuxième brin 4.We will now describe the installation of the clasp and its release from the second strand 4.

A la figure 3, une pression est exercée simultanément sur les poussoirs 26 pour déplacer les parties déformables 23,24 et ainsi réduire l'écartement entre les pions et les rapprocher avant de les insérer dans un trou 40 du second brin de bracelet 4.To the Figure 3 , pressure is exerted simultaneously on the pushers 26 to move the deformable parts 23,24 and thus reduce the spacing between the pins and bring them together before inserting them into a hole 40 of the second strand of bracelet 4.

Les pions 6 sont insérés dans le trou 40 jusqu'à ce que les crochets 6' dépassent du trou 40. Le porteur peut alors relâcher la pression sur les poussoirs 26, ce qui provoque un retour à la position de repos des parties déformables 23,24 et par conséquence des crochets également qui viennent en prise avec le second brin de bracelet, ce qui provoque le verrouillage du fermoir sur le second brin de bracelet.The pins 6 are inserted into the hole 40 until the hooks 6' protrude from the hole 40. The wearer can then release the pressure on the pushers 26, which causes a return to the rest position of the deformable parts 23, 24 and consequently also hooks which engage with the second strand of bracelet, which causes the clasp to lock on the second strand of bracelet.

Pour ouvrir le fermoir, des pressions simultanées doivent être exercées sur les poussoirs 26 pour provoquer la libération des crochets 6' du trou 40 et l'ouverture du fermoir.To open the clasp, simultaneous pressure must be exerted on the pushers 26 to cause the release of the hooks 6' from the hole 40 and the opening of the clasp.

Bien entendu, la présente invention est définie par les revendications annexées et ne se limite pas à l'exemple illustré mais est susceptible de diverses variantes et modifications qui apparaîtront à l'homme de l'art.Of course, the present invention is defined by the appended claims and is not limited to the example illustrated but is susceptible to various variants and modifications which will appear to those skilled in the art.
