Description
La présente invention se rapporte au domaine de l'horlogerie ou de la bijouterie. Elle concerne plus précisément un dispositif de fixation d'un bracelet à un objet, notamment une boîte de montre.The present invention relates to the field of watchmaking or jewelry. It relates more precisely to a device for attaching a bracelet to an object, in particular a watch case.
Généralement, les bracelets, en cuir ou en métal, sont fixés aux cornes d'une boîte de montre, par l'intermédiaire d'une barrette formée d'un tube, dans lequel sont montés deux pistons mobiles en translation, et un organe élastique disposé entre lesdits pistons et tendant à les chasser vers l'extérieur du tube. Ladite barrette est montée dans un logement prévu à cet effet à une extrémité du bracelet, et les pistons sont engagés dans des alésages borgnes réalisés en vis-à-vis dans les cornes de la boîte.Generally, the straps, in leather or in metal, are fixed to the horns of a watch case, by means of a bar formed of a tube, in which are mounted two pistons movable in translation, and an elastic member. disposed between said pistons and tending to drive them out of the tube. Said bar is mounted in a housing provided for this purpose at one end of the bracelet, and the pistons are engaged in blind bores made opposite in the horns of the box.
Pour désolidariser un bracelet ainsi fixé à une boîte, il faut disposer d'un outil conçu pour repousser les pistons dans le tube, à l'encontre de la contrainte exercée par l'organe élastique, et les extraire ainsi des alésages. Le porteur de la montre n'est pas en permanence muni d'un tel outil, et de plus, son utilisation peut s'avérer incommode. C'est pourquoi les bracelets munis d'un tel dispositif de fixation sont généralement attachés de manière permanente à la boîte.To separate a bracelet thus fixed to a box, it is necessary to have a tool designed to push the pistons back into the tube, against the stress exerted by the elastic member, and thus extract them from the bores. The wearer of the watch is not permanently provided with such a tool, and furthermore, its use can prove to be inconvenient. This is why the straps provided with such a fixing device are generally permanently attached to the case.
Il existe par ailleurs des dispositifs de fixation permettant de désolidariser le bracelet de la boîte sans recourir à un outil, tels que les dispositifs de fixation des documents
Le brevet
Les dispositifs de fixations ainsi décrits sont généralement employés pour des bracelets interchangeables, qu'ils permettent de remplacer au gré du porteur. Ils ne sont toutefois pas exempts d'inconvénients. On notera, en particulier, qu'ils nécessitent des modifications structurelles majeures au niveau de la barrette, telles que, par exemple, la réalisation d'une ouverture au niveau du tube, ou la transformation des pistons. Ces changements entraînent des surcoûts de fabrication importants. Ces dispositifs de fixation comportent, par ailleurs, un élément proéminent, à savoir l'organe d'actionnement, qui peut s'accrocher ou blesser le porteur de la montre.The fastening devices thus described are generally used for interchangeable straps, which they can replace at the option of the wearer. However, they are not without drawbacks. It will be noted, in particular, that they require major structural modifications at the level of the bar, such as, for example, the creation of an opening at the level of the tube, or the transformation of the pistons. These changes lead to significant additional manufacturing costs. These fixing devices also include a prominent element, namely the actuating member, which can catch on or injure the wearer of the watch.

Le logement 21 présente une ouverture 210 sensiblement rectangulaire pour recevoir le méplat 41 de la barrette 4, la hauteur et la longueur de l'ouverture 210 correspondant à la hauteur et à la longueur des méplats 41 de la barrette 4.The
Selon le mode de réalisation préférentiel de l'invention illustré sur les figures, la barrette 4 comprend deux méplats 41 disposé à proximité de chacune des extrémités de la barrette 4, de façon à ce qu'il y ait un méplat 41 de part et d'autre de la corne médiane, chacun des méplats 41 coopérant avec un insert 20.According to the preferred embodiment of the invention illustrated in the figures, the bar 4 comprises two
Avantageusement, la barrette 4 comprend au moins un organe de commande de manière à la faire pivoter d'une première position A dans laquelle le méplat 41 de la barrette 4 est apte à recevoir l'insert, vers une deuxième position B dans laquelle ledit insert est verrouillé sur la barrette 4.Advantageously, the bar 4 comprises at least one control member so as to rotate it from a first position A in which the flat 41 of the bar 4 is capable of receiving the insert, towards a second position B in which said insert is locked on the bar 4.
Selon un mode de réalisation particulier de l'invention, la barrette 4 peut être ramenée de la position B vers la position A par des moyens de rappel élastiques tel qu'un ressort sautoir sur excentrique ou encore ressort de torsion sur la barrette.According to a particular embodiment of the invention, the bar 4 can be brought back from position B to position A by elastic return means such as a jumper spring on an eccentric or else a torsion spring on the bar.
Tel qu'illustré, l'organe de commande comprend une collerette 43 solidaire de chacune des extrémités de la barrette 4, la barrette 4 et les collerettes 43 formant alors un élément unique. Il peut aussi être envisagé d'assembler la collerette 43 à l'extrémité de la barrette 4 par l'intermédiaire d'une pointe d'insertion montée dans une partie creuse de la barrette 4. Un renflement interne est alors aménagé à l'extrémité de la barrette 4 pour coopérer avec la pointe d'insertion, afin de clipper la collerette 43 dans la barrette 4. D'autres modes de fixation des collerettes 43 peuvent être envisagés, comme par exemple par collage, soudage, ou encore par chassage.
