Description

Domaine de l'inventionField of the invention

L'invention concerne un dispositif de fixation d'un fond sur une carrure d'une montre.The invention relates to a device for fixing a caseback to a middle part of a watch.

L'invention concerne encore une pièce d'horlogerie, notamment une montre, comportant un tel dispositif.The invention also relates to a timepiece, in particular a watch, comprising such a device.

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. This angular indexing is often tricky to achieve properly, in combination with good tightening of the components and perfect sealing of the joints.

Il est connu d'utiliser un élément élastique de fermeture, indépendant des organes à assembler, comme dans le document CH 423 637 ou dans le brevet CH 447 046 . L'inconvénient des éléments élastiques proposés dans ces documents réside essentiellement dans leur encombrement. Il est également connu du document CH 512 769 d'utiliser des plots en matériaux compressibles entourés de segments de couronne qui coopèrent avec des fraisages ménagés aux angles d'un boîtier carré ou rectangulaire. Un tel dispositif n'est utilisable que sur des boîtiers de forme et l'élasticité donnée par un matériau compressible de type élastomère qui est susceptible de se modifier de manière importante au cours du vieillissement de la matière.It is known to use an elastic closure element, independent of the members to be assembled, as in the document CH 423 637 or in the patent CH 447 046 . The drawback of the elastic elements proposed in these documents lies essentially in their size. It is also known from the document CH 512 769 to use studs made of compressible materials surrounded by crown segments which cooperate with millings provided at the corners of a square or rectangular case. Such a device can only be used on casings with the shape and elasticity given by a compressible material of the elastomer type which is liable to change significantly during the aging of the material.

Résumé de l'inventionSummary of the invention

L'invention se propose de réaliser un assemblage étanche et sécurisé de composants d'habillage avec un indexage angulaire facile à régler.The invention proposes to produce a sealed and secure assembly of trim components with easy-to-adjust angular indexing.

A cet effet, l'invention concerne un dispositif de fixation d'un fond sur une carrure selon la revendication 1.To this end, the invention relates to a device for fixing a back to a caseband according to claim 1.

L'invention concerne encore une pièce d'horlogerie comportant un tel dispositif de fixation.The invention also relates to a timepiece comprising such a fixing device.

Description détaillée des modes de réalisation préférésDetailed Description of Preferred Embodiments

L'invention se propose de réaliser un assemblage étanche et sécurisé de composants d'habillage avec un indexage angulaire facile à régler, et dans une position garantie, et ceci avec un nombre minimal de composants, et des coûts de fabrication réduits.The invention proposes to produce a sealed and secure assembly of trim components with easy-to-adjust angular indexing, and in a guaranteed position, and this with a minimum number of components, and reduced manufacturing costs.

Les figures 1 à 5 illustrent l'exemple non limitatif du montage et de l'indexage angulaire d'un fond par rapport à une carrure de montre.The figures 1 to 5 illustrate the non-limiting example of mounting and angular indexing of a back relative to a watch middle.

L'invention concerne un dispositif de fixation 100 d'un fond 2 sur une carrure 1 d'une montre, le fond 2 comprenant un couvercle 20 agencé pour former une surface d'appui avec la carrure 1 et un corps 21 agencé pour reposer dans la carrure, ledit dispositif comprenant une bague 4 disposée entre le fond 2 et la carrure 1, ladite bague 4 étant agencée pour assurer l'étanchéité et l'indexation du fond. La bague 4 comprend une partie supérieure 40 assurant l'étanchéité et une partie médiane 41 comprenant des moyens de positionnement 3 pour assurer l'indexation du fond 2 par rapport à la carrure 1.The invention relates to a device 100 for fixing a back 2 to a middle part 1 of a watch, the back part 2 comprising a cover 20 arranged to form a bearing surface with the middle part 1 and a body 21 arranged to rest in the caseband, said device comprising a ring 4 placed between the caseback 2 and the caseband 1, said ring 4 being arranged to provide sealing and indexing of the caseback. The ring 4 comprises an upper part 40 ensuring the seal and a middle part 41 comprising positioning means 3 to ensure the indexing of the back 2 with respect to the middle part 1.

Comme on peut l'observer à la figure 1b, la carrure 1 présente un épaulement 10 sur lequel repose la partie supérieure 40 de la bague 4, la bague 4 étant affleurante avec la carrure une fois mise en place.As can be observed at the figure 1b , the caseband 1 has a shoulder 10 on which rests the upper part 40 of the ring 4, the ring 4 being flush with the caseband once in place.

Avantageusement, les moyens de positionnement 3 comprennent au moins un ergot 43 formé sur la partie médiane 41 de la bague 4 et agencé pour reposer dans un logement 11 de la carrure 1, l'ergot 43 étant formé sur la paroi extérieure et s'étendant sur tout ou partie de la hauteur de la partie médiane 41 de la bague 4. Ainsi, la bague 4 ne peut pas être déplacée en rotation lorsqu'un couple est imprimé au fond par exemple.Advantageously, the positioning means 3 comprise at least one lug 43 formed on the middle part 41 of the ring 4 and arranged to rest in a housing 11 of the middle part 1, the lug 43 being formed on the outer wall and extending over all or part of the height of the middle part 41 of the ring 4. Thus, the ring 4 cannot be moved in rotation when a torque is imparted to the bottom, for example.

La bague 4 comprend également un ergot 46 agencé pour coopérer avec un usinage 22 formé dans le fond 2. Un tel agencement permet le bon positionnement, ou la bonne indexation, du fond 2 par rapport à la carrure 1, ce qui est particulièrement utile lorsque le fond 2 présente une décoration et que celle-ci doit être parfaitement alignée selon l'axe 12h-6h de la montreThe ring 4 also comprises a lug 46 arranged to cooperate with a machining 22 formed in the back 2. Such an arrangement allows the correct positioning, or the correct indexing, of the back 2 with respect to the caseband 1, which is particularly useful when the back 2 has a decoration and that this must be perfectly aligned along the 12 o'clock-6 o'clock axis of the watch

Selon une variante de l'invention illustrée aux figures 4 et 5, la bague 4 présente une partie inférieure 42, la partie inférieure 42 présentant des moyens de maintien agencés pour coopérer avec le fond 2, les moyens de maintien se présentant sous la forme d'un clip saillant 420 agencé pour se loger dans une rainure ou un logement formé dans le corps 21 du fond 2.According to a variant of the invention illustrated in figures 4 and 5 , the ring 4 has a lower part 42, the lower part 42 having holding means arranged to cooperate with the bottom 2, the holding means being in the form of a projecting clip 420 arranged to be housed in a groove or a housing formed in the body 21 of the bottom 2.

Dans cette optique, la bague 4 est réalisée dans une matière polymère telle que l'asutane® ou l'hytrel®. Bien évidemment, toute autre matière acceptant d'être déformée élastiquement, et suffisamment résistante, peut être utilisée pour réaliser la bague 4. Les nervures externes 44 et internes 45 permettent ainsi d'obtenir une bonne résistance au déchassage une fois le fond 2 monté, emboité en force ou chassé, sur la carrure 1.With this in mind, ring 4 is made of a polymer material such as asutane ® or hytrel ® . Obviously, any other material accepting to be deformed elastically, and sufficiently resistant, can be used to make the ring 4. The external 44 and internal 45 ribs thus make it possible to obtain a good resistance to loosening once the bottom 2 is mounted, interlocked in force or driven out, on middle 1.

Selon un mode de réalisation préférentiel de l'invention, la bague 4 comprend au moins deux nervures internes 45 et au moins deux nervures externes 44, les nervures étant espacées angulairement les unes des autres de 60° à 90°. Les nervures internes 45 et les nervures externes 44 sont prévues pour être décalées les unes par rapport aux autres, c'est-à-dire qu'une nervure externe ne sera pas positionnée face à une nervure interne, et ainsi fournir un meilleur maintien.According to a preferred embodiment of the invention, the ring 4 comprises at least two internal ribs 45 and at least two external ribs 44, the ribs being spaced angularly from each other by 60° to 90°. The internal ribs 45 and the external ribs 44 are designed to be offset with respect to each other, that is to say that an external rib will not be positioned facing an internal rib, and thus provide better support.

Le fond 2 et la bague 4 sont dimensionnés de telle sorte que, lorsqu'ils sont introduits à force dans la carrure 1, le fond 2 presse radialement la bague 4 contre ladite carrure 28, ce qui a pour effet de comprimer ledit élément élastique 4 entre la paroi de la carrure et le fond. La bague 4 comporte en particulier des nervures qui s'étendent sur toute ou partie de sa hauteur et qui, en réaction à la force de compression, vont se déformer et garantir un bon maintien de l'ensemble. Un taux de compression de la bague 4 de l'ordre de 20 % est préféré pour fournir un bon maintien. Un tel taux provoque une augmentation des forces de frottement entre le fond 2 et la bague 4 d'une part, et entre la bague 4 et la carrure 1 d'autre part, et détermine donc les couples mis en jeu pour la mise en place du fond 2 sur la montre.The bottom 2 and the ring 4 are dimensioned such that, when they are forced into the middle part 1, the bottom 2 radially presses the ring 4 against the said middle part 28, which has the effect of compressing the said elastic element 4 between the wall of the middle and the back. The ring 4 comprises in particular ribs which extend over all or part of its height and which, in reaction to the compressive force, will deform and guarantee good maintenance of the assembly. A compression rate of the ring 4 of the order of 20% is preferred to provide good support. Such a rate causes an increase in the friction forces between the back 2 and the ring 4 on the one hand, and between the ring 4 and the caseband 1 on the other hand, and therefore determines the torques involved for the establishment bottom 2 on the watch.

La figure 3 illustre une vue en coupe du fond 2 et de la bague 4 assemblés sur la carrure 1, la bague 4 étant comprimée entre la face latérale interne de la carrure 1 et le fond 2. La mise en place en force du fond dans la carrure maintient la bague 4 déformée, et plus particulièrement les rainures externes. Cette déformation se situe évidemment dans la limite de déformation élastique de la matière de la bague.The picture 3 illustrates a sectional view of the back 2 and of the ring 4 assembled on the caseband 1, the ring 4 being compressed between the lateral face inside the caseband 1 and the back 2. The forceful fitting of the caseback in the caseband keeps the ring 4 deformed, and more particularly the external grooves. This deformation is obviously within the elastic deformation limit of the material of the ring.

L'invention concerne aussi une pièce d'horlogerie ou montre 1000 comportant un tel dispositif de fixation 100.The invention also relates to a timepiece or watch 1000 comprising such a fixing device 100.

En somme, l'invention permet de disposer d'un dispositif de fixation dont la conception est peu encombrante, assure le maintien de l'étanchéité de la montre, et protège contre tout démontage accidentel.In short, the invention makes it possible to have a fastening device whose design is not bulky, ensures that the watertightness of the watch is maintained, and protects against any accidental dismantling.

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