Description
L'invention concerne une couronne vissée orientable pour une boîte de montre comportant une carrure avec au moins un logement traversant pour la réception de ladite couronne vissée orientable, laquelle couronne vissée orientable est agencée pour coopérer avec ledit logement et l'obturer de façon étanche, ladite couronne vissée orientable comportant un motif sur une face d'extrémité ou à son voisinage, ladite couronne vissée orientable comportant, mobiles axialement selon une direction axiale l'un par rapport à l'autre, d'une part un sous-ensemble comportant un corps de couronne manipulable par un utilisateur et comportant ledit motif, et d'autre part un tube agencé pour être vissé ou chassé dans ledit logement selon ladite direction axiale.The invention relates to an orientable screwed crown for a watch case comprising a middle part with at least one through housing for receiving said orientable screwed crown, which orientable screwed crown is arranged to cooperate with said housing and seal it in a sealed manner, said orientable screwed crown comprising a pattern on an end face or in its vicinity, said orientable screwed crown comprising, movable axially in an axial direction with respect to each other, on the one hand a sub-assembly comprising a crown body that can be handled by a user and comprising said pattern, and on the other hand a tube arranged to be screwed or driven into said housing in said axial direction.
L'invention concerne encore une boîte de montre, comportant une carrure avec au moins un logement traversant pour la réception d'une telle couronne vissée orientable.The invention also relates to a watch case, comprising a middle part with at least one through housing for receiving such an orientable screw-down crown.
L'invention concerne encore une pièce d'horlogerie, notamment une montre, comportant une telle boîte.The invention also relates to a timepiece, in particular a watch, comprising such a case.
L'invention concerne encore un procédé d'assemblage d'une telle couronne vissée orientable.The invention also relates to a method of assembling such an orientable screwed crown.
L'invention concerne encore un procédé de montage d'une telle couronne vissée orientable sur une boîte de montre.The invention also relates to a method for mounting such an orientable screwed crown on a watch case.
Les couronnes vissées sont couramment utilisées pour équiper des montres dans le but d'améliorer leur étanchéité au niveau du passage d'un organe de commande, tel qu'une tige de remontage ou de commande. Ce type de couronne a la particularité de pouvoir prendre une position dévissée dans laquelle la montre peut être remontée, mise à l'heure, réglée, ou autre, et une position vissée dans laquelle la couronne est vissée et bloquée sur un tube chassé ou vissé dans la carrure de la boîte de montre afin de comprimer un joint d'étanchéité, améliorant ainsi l'étanchéité de la montre. La position vissée est donc celle qui correspond à la position normale lorsque la montre est portée et qui est toujours à peu près la même, à l'usure du joint d'étanchéité près.Screw-down crowns are commonly used to equip watches with the aim of improving their sealing at the passage of a control member, such as a winding or control rod. This type of crown has the particularity of being able to take an unscrewed position in which the watch can be wound, time-set, adjusted, or other, and a screwed position in which the crown is screwed and blocked on a driven or screwed tube. in the middle of the watch case in order to compress a gasket, thus improving the watertightness of the watch. The screwed position is therefore that which corresponds to the normal position when the watch is worn and which is always roughly the same, apart from the wear of the seal.
La fabrication et le montage de ces couronnes vissées sur des boîtes de montre sont bien connus. Toutefois, les procédés de montage de ces couronnes sont mal adaptés aux couronnes vissées qui portent sur leur face d'extrémité une inscription ou un motif, par exemple un logo, une marque de fabrique ou un signe analogue, ou encore un relief, ou aux couronnes qui ne sont pas de révolution, alors qu'il est souhaitable que l'utilisateur, ou tout au moins un service d'après-vente, puisse procéder au réglage d'indexation angulaire d'une telle couronne, en position vissée, selon une orientation particulière désirée.The manufacture and assembly of these screwed crowns on watch cases are well known. However, the methods of mounting these crowns are ill-suited to screw-down crowns which bear on their end face an inscription or a pattern, for example a logo, a trademark or a similar sign, or even a relief, or to crowns which are not of revolution, whereas it is desirable for the user, or at least an after-sales service, to be able to adjust the angular indexing of such a crown, in the screwed position, according to a particular orientation desired.
En effet, les procédés de montage connus ne permettent généralement pas d'amener la couronne dans une orientation déterminée par rapport à la boîte après son vissage, ce qui peut nuire à l'esthétique de la boîte. Cette situation est bien entendu inacceptable lorsque ces couronnes équipent des produits de luxe et de haute qualité.In fact, the known mounting methods generally do not allow the crown to be brought into a determined orientation with respect to the case after it has been screwed in, which can be detrimental to the aesthetics of the case. This situation is of course unacceptable when these crowns equip luxury and high quality products.
L'invention a notamment pour objectif de pallier les différents inconvénients de ces techniques connues.The object of the invention is in particular to overcome the various drawbacks of these known techniques.
Plus précisément, un objectif de l'invention est de fournir une couronne vissée orientable adaptable à toute boîte de montre comportant un logement de couronne, pour l'orientation de cette couronne vissée, réalisée selon une construction simple et économique.More precisely, an objective of the invention is to provide an orientable screwed crown adaptable to any watch case comprising a crown housing, for the orientation of this screwed crown, produced according to a simple and economical construction.
L'invention a également pour objectif de fournir une couronne vissée orientable plus fiable que celles existantes.Another objective of the invention is to provide an orientable screwed crown that is more reliable than existing ones.
Ainsi, l'invention concerne une couronne vissée orientable selon la revendication 1.Thus, the invention relates to an orientable screwed crown according to
