Arrière-plan de l'inventionBackground of the invention

L'habillage des montres et appareils similaires obéit à de nombreuses contraintes, en particulier d'étanchéité, de robustesse, d'aspect, et doit être réalisé de façon à prévenir tout démontage involontaire se traduisant irrémédiablement par une intervention d'après-vente pour échange de joints, nettoyage, lubrification, voire réparation.The dressing of watches and similar devices is subject to numerous constraints, in particular sealing, robustness, appearance, and must be carried out in such a way as to prevent any involuntary disassembly resulting irremediably in an after-sales intervention for exchange of seals, cleaning, lubrication, even repair.

Certains composants d'habillage ou de commande doivent, encore, être indexés angulairement les uns par rapport aux autres, pour des repérages de position de référence d'origine, de repos, ou d'actionnement, ou encore pour faciliter la lecture d'indications ou de graduations, ou pour assurer la continuité de surfaces gauches et/ou de décors. Cet indexage angulaire est souvent délicat à bien réaliser, en combinaison avec un bon serrage des composants et avec une étanchéité parfaite des joints.Certain trim or control components must still be indexed angularly with respect to each other, for markings of the original reference position, of rest, or of actuation, or even to facilitate the reading of indications or graduations, or to ensure the continuity of uneven surfaces and/or decorations.

  • on insère la bague 5 fendue élastique dans le deuxième composant 2,
  • on insère dans la bague 5 chaque insert amovible 4 que comporte le verrou 3,
  • on positionne le au moins un joint d'étanchéité et de friction 9 entre le deuxième composant 2 et le premier composant 1,
  • on visse ensemble le verrou 3 et le premier composant 1, tout d'abord en entraînant le deuxième composant 2 par rapport au verrou 3 jusqu'à ce qu'un relief inférieur 41 arrive dans une première position de butée à une première extrémité de la course angulaire, puis en effectuant le vissage complet au couple préconisé entre le verrou 3 et le premier composant 1,
  • puis on oriente angulairement le deuxième composant 2 par rapport au premier composant 1 en l'entraînant dans le sens opposé au sens de vissage jusqu'à la position désirée.
More particularly, according to this method:
  • the elastic split ring 5 is inserted into the second component 2,
  • each removable insert 4 included in the lock 3 is inserted into the ring 5,
  • the at least one seal and friction seal 9 is positioned between the second component 2 and the first component 1,
  • the bolt 3 and the first component 1 are screwed together, first of all by driving the second component 2 with respect to the bolt 3 until a lower relief 41 reaches a first abutment position at a first end of the angular travel, then carrying out the complete tightening at the recommended torque between the lock 3 and the first component 1,
  • then the second component 2 is oriented angularly with respect to the first component 1 by driving it in the direction opposite to the screwing direction to the desired position.

Plus particulièrement, pour procéder au démontage du sous-ensemble d'habillage 100, on poursuit l'entraînement du deuxième composant 2 dans le sens opposé au sens de vissage jusqu'à ce qu'un relief inférieur arrive dans une deuxième position de butée à l'autre extrémité de la course angulaire, autorisant l'entraînement du verrou 3 pour son dévissage du premier composant 1.More particularly, to dismantle the trim sub-assembly 100, the driving of the second component 2 is continued in the opposite direction to the screwing direction until a lower relief reaches a second stop position at the other end of the angular travel, allowing the driving of the lock 3 for its unscrewing of the first component 1.

L'invention permet d'assurer l'orientation parfaite d'un composant maintenu bloqué dans sa position de service.The invention makes it possible to ensure the perfect orientation of a component held locked in its service position.

L'invention autorise, encore, la mise en coopération de composants antagonistes réalisés en matières de différentes natures, sans contrainte de dilatation frottement, élasticité, ou autre, sans nécessiter d'élément de fixation extérieur tel que vis ou similaire, sans pas de vis ni usinage risquant de fragiliser des matières particulières telles que céramiques, saphir, et similaires. Elle présente une très bonne résistance à un dévissage accidentel ou même volontaire par vibration ou du type Chapuis-chocs. L'invention permet aussi d'assurer l'interchangeabilité des composants, et, par conséquent, une personnalisation accrue des montres ou des bijoux des utilisateurs.The invention also authorizes the cooperation of antagonistic components made of materials of different natures, without expansion, friction, elasticity or other stress, without requiring an external fixing element such as a screw or the like, without a screw thread. or machining that risks weakening particular materials such as ceramics, sapphire, and the like. It has very good resistance to accidental or even deliberate unscrewing by vibration or of the Chapuis-shock type. The invention also makes it possible to ensure the interchangeability of the components, and, consequently, an increased personalization of the watches or the jewelery of the users.

Cette invention est applicable aussi bien à des montres ou bijoux réalisés en matériaux précieux qu'à des réalisations de grande série comportant des composants de faible coût unitaire, notamment en matière plastique ou similaire.This invention is applicable both to watches or jewelry made of precious materials and to mass-produced productions comprising components of low unit cost, in particular made of plastic or the like.

L'invention se prête bien aux cas où le sous-ensemble 100 comporte des composants réalisés dans des matériaux différents, avec des coefficients de dilatation différents, ou encore des matières fragiles, ou dures (céramique, saphir, pierres précieuses, gemmes, camées), qui n'autorisent pas des modes de fixation standard. Citons parmi des configurations classiques l'assemblage d'une carrure en or avec un fond saphir, ou encore une boîte entièrement en céramique, une combinaison métal-céramique, ou similaires. Les composants peuvent ainsi être réalisés en toutes sortes de matériaux : alliages métalliques, notamment précieux ou titrés, aciers inoxydables, alliages métalliques au moins partiellement amorphe, ou « Liquidmetal© » ou similaire, céramiques, saphir, minéraux, pierres dures, caoutchouc, matières plastiques et notamment élastomères thermoplastiques dits TPE dont notamment polyuréthane thermoplastique dit TPU, polycarbonates dits PC, chlorures de polyvinyle dits PVC, polyacétals ou polyoxyméthylène dit POM, silicone, « Nylon® », pour ne citer, non limitativement, que des matériaux usuels en construction horlogère et en bijouterie-joaillerie.The invention lends itself well to cases where the sub-assembly 100 comprises components made of different materials, with different coefficients of expansion, or else fragile or hard materials (ceramic, sapphire, precious stones, gems, cameos) , which do not allow standard fixing methods. Among the classic configurations, we can cite the assembly of a middle part in gold with a sapphire back, or even a case entirely in ceramic, a metal-ceramic combination, or the like. The components can thus be made of all kinds of materials: metal alloys, in particular precious or titrated, stainless steels, at least partially amorphous metal alloys, or "Liquidmetal © " or similar, ceramics, sapphire, minerals, hard stones, rubber, materials plastics and in particular thermoplastic elastomers called TPE, including in particular thermoplastic polyurethane called TPU, polycarbonates called PC, polyvinyl chlorides called PVC, polyacetals or polyoxymethylene called POM, silicone, "Nylon ® ", to cite, without limitation, only usual construction materials watchmaking and jewelry.
