Description détaillée des modes de réalisation préférésDetailed Description of the Preferred Embodiments

Un dispositif d'attache conforme à l'invention va maintenant être décrit dans ce qui suit faisant référence conjointement aux figures 1 et 2a à 2d.A fastener according to the invention will now be described in the following with reference to figures 1 and 2a to 2d .

Tel qu'illustré à la figure 1, le dispositif d'attache comprend deux éléments 1 et 2 d'un bracelet de montre pour permettre l'accrochage ou le décrochage des deux éléments 1, 2. Comme on peut l'observer, le premier élément 1 comprend au moins une barrette 10 à l'une de ses extrémités. Les deux éléments 1,2 peuvent consister en un brin de bracelet pour le premier élément, et en un fermoir pour le second élément par exemple.As illustrated in figure 1 , the attachment device comprises two elements 1 and 2 of a watch strap to allow the hooking or unhitching of the two elements 1, 2. As can be seen, the first element 1 comprises at least one bar 10 at one of its ends. The two elements 1,2 may consist of a bracelet strand for the first element, and a clasp for the second element for example.

Le second élément 2 comprend deux gouttières fixes 20, 21 comprenant chacune une ouverture longitudinale 210, 220 respectivement opposée l'une à l'autre. Avantageusement, le second élément 2 est réalisé d'un seul bloc.The second element 2 comprises two fixed gutters 20, 21 each comprising a longitudinal opening 210, 220 respectively opposite to each other. Advantageously, the second element 2 is made of a single block.

Selon l'invention, l'un des deux éléments peut passer d'une position décrochée dans laquelle l'un des deux éléments est orienté selon une position angulaire prédéterminée par rapport à l'autre élément, vers une position accrochée dans laquelle les deux éléments 1, 2 sont coplanaires après une rotation d'un angle prédéterminé d'un des deux éléments par rapport à l'autre de manière que chaque gouttière est articulée sur la barrette 10 et maintenir accrochés l'un à l'autre les deux éléments 1, 2.According to the invention, one of the two elements can pass from an unhooked position in which one of the two elements is oriented according to a predetermined angular position with respect to the other element, towards a hooked position in which the two elements 1, 2 are coplanar after a rotation of a predetermined angle of one of the two elements relative to each other so that each channel is articulated on the bar 10 and keep hooked together the two elements 1 , 2.

De manière préférentielle, l'un des deux éléments est positionné perpendiculairement par rapport à l'autre, l'un des éléments étant dans le plan transverse et l'autre dans le plan sagittal. Ainsi, la rotation de l'un des deux éléments est comprise entre 0° et 90°, et plus préférentiellement entre 45° et 90°. La rotation peut être effectuée dans le sens horaire ou antihoraire selon l'orientation des gouttières 20, 21.Preferably, one of the two elements is positioned perpendicular to the other, one of the elements being in the transverse plane and the other in the sagittal plane. Thus, the rotation of one of the two elements is between 0 ° and 90 °, and more preferably between 45 ° and 90 °. The rotation can be carried out clockwise or counterclockwise according to the orientation of the gutters 20, 21.

Avantageusement, les ouvertures longitudinale 210, 220 respectives des gouttières 20, 21 présentent des dimensions légèrement inférieures à la barrette 10 de manière à prévenir tout décrochage intempestif, l'ouverture ayant une largeur légèrement inférieure au diamètre de la barrette 10. Ainsi, lors de la mise en place des gouttières 20, 21 sur la barrette 10, l'utilisateur doit forcer légèrement pour insérer la barrette 10 et entendre un « clic » signifiant la bonne mise en place des gouttières 20, 21 sur la barrette 10.Advantageously, the respective longitudinal openings 210, 220 of the gutters 20, 21 have dimensions slightly smaller than the bar 10 so as to prevent any inadvertent stall, the opening having a width slightly less than the diameter of the bar 10. Thus, when the installation of the gutters 20, 21 on the bar 10, the user must force slightly to insert the bar 10 and hear a "click" signifying the proper placement of the gutters 20, 21 on the bar 10.

Comme on peut l'observer à la figure 1, les gouttières 20 et 21 comprennent chacune un logement de forme cylindrique droit dans lequel débouche les ouvertures longitudinales 210, 220, le diamètre du logement étant prévu légèrement supérieur au diamètre de la barrette 10 pour limiter les frottements et faciliter la rotation lors du pivotement d'un élément par rapport à l'autre. Toutefois, le diamètre du logement ne devra pas être trop supérieur pour éviter un jeu trop grand et désagréable pour le porteur.As can be seen at figure 1 gutters 20 and 21 each comprise a straight cylindrical housing into which the longitudinal openings 210, 220 open, the diameter of the housing being provided slightly greater than the diameter of the bar 10 to limit friction and facilitate rotation when pivoting. one element in relation to the other. However, the diameter of the housing should not be too great to avoid a game too big and unpleasant for the wearer.

Comme on peut l'observer à la figure 1, le premier élément comprend un élément central 11 entourant la barrette 10, et le second élément 2 comprend un espace libre 22, disposé entre les deux gouttières 20,21 et agencé pour recevoir l'élément central 11 du premier élément 1. Les deux gouttières 20, 21 sont distantes l'une de l'autre et définissent un espace 22 entre elles qui est agencé pour recevoir l'élément central 11 lors de la mise en place du premier élément avec le second élément.As can be seen at figure 1 , the first element comprises a central element 11 surrounding the bar 10, and the second element 2 comprises a free space 22, arranged between the two channels 20, 21 and arranged to receive the central element 11 of the first element 1. The two gutters 20, 21 are spaced from each other and define a space 22 between them which is arranged to receive the central element 11 at the time of setting place the first element with the second element.

Selon l'invention, un tel dispositif d'attache peut aussi bien servir pour un bracelet de type souple en cuir, en textile ou en une matière plastique, pour attacher le bracelet à un boîtier ou à un fermoir, que pour attacher un bracelet à maillon à un fermoir.According to the invention, such a fastening device can also be used for a flexible type bracelet made of leather, textile or a plastic material, for attaching the bracelet to a case or clasp, as for attaching a bracelet to link to a clasp.

Les figures 2a à 2d illustrent les différentes étapes pour assembler les deux éléments 1 et 2.The Figures 2a to 2d illustrate the different steps to assemble the two elements 1 and 2.

Dans un premier temps, le premier élément 1 et le second élément 2 sont disposés perpendiculairement l'un par rapport à l'autre comme illustré à la figure 2a. Les deux éléments 1 et 2 sont ensuite disposés l'un contre l'autre perpendiculairement de façon que l'élément central 10 repose dans l'espace 22 comme illustré à la figure 2b.In a first step, the first element 1 and the second element 2 are arranged perpendicularly relative to each other as illustrated in FIG. figure 2a . The two elements 1 and 2 are then placed against each other perpendicularly so that the central element 10 rests in the space 22 as illustrated in FIG. figure 2b .

Enfin, l'utilisateur fait pivoter l'un des deux éléments par rapport à l'autre autour de l'élément central 11 comme visible à la figure 2c, jusqu'à ce que la barrette 10 viennent se loger dans chacune des gouttières 20, 21.Finally, the user rotates one of the two elements relative to the other around the central element 11 as visible to the Figure 2c , until the bar 10 are housed in each of the gutters 20, 21.

Bien évidemment, un premier élément sans élément central 11 entourant la barrette 10 est envisageable, l'élément central 11 facilitant la mise en place du second élément 2 et servant de repère pour la rotation.Obviously, a first element without central element 11 surrounding the bar 10 is conceivable, the central element 11 facilitating the establishment of the second element 2 and serving as a reference for the rotation.

Grâce à ces différents aspects de l'invention, on dispose d'un dispositif d'attache permettant de monter et/ou démonter rapidement et facilement deux éléments d'un bracelet ou de monter/démonter un bracelet à une boite de montre sans nécessiter d'outils particulier.Thanks to these different aspects of the invention, there is a fastening device for mounting and / or disassembling quickly and easily two elements of a bracelet or to assemble / disassemble a bracelet to a watch case without requiring d tools.

Bien entendu, la présente invention ne se limite pas à l'exemple illustré et est susceptible de diverses variantes et modifications qui apparaîtront à l'homme de l'art.Of course, the present invention is not limited to the illustrated example and is susceptible of various variations and modifications that will occur to those skilled in the art.
