Description

Domaine de l'inventionField of the invention

L'invention concerne une couronne vissée pour une boîte de montre comportant une carrure avec au moins un logement traversant pour la réception de ladite couronne vissée, laquelle couronne vissée comporte un tube agencé pour être inséré dans ledit logement selon une direction axiale autour d'un axe de couronne, et ladite couronne vissée étant agencée pour obturer ledit logement de façon étanche, ladite couronne vissée comportant un sous-ensemble comportant un corps de couronne manipulable par un utilisateur, ledit sous-ensemble étant mobile axialement selon ladite direction axiale par rapport audit tube, et ledit sous-ensemble comportant au moins un mécanisme à ressort avec au moins un ressort monté en compression dans une chambre et s'étendant selon ladite direction axiale.The invention relates to a screwed crown for a watch case comprising a middle part with at least one through housing for receiving said screwed crown, which screwed crown comprises a tube arranged to be inserted into said housing in an axial direction around a crown axis, and said screwed crown being arranged to seal off said housing, said screwed crown comprising a sub-assembly comprising a crown body that can be handled by a user, said sub-assembly being movable axially in said axial direction with respect to said tube, and said sub-assembly comprising at least one spring mechanism with at least one spring mounted in compression in a chamber and extending in said axial direction.

L'invention concerne encore une boîte de montre comportant au moins un logement pour la réception d'une couronne vissée, et une couronne vissée agencée pour coopérer avec ledit logement et l'obturer de façon étanche.The invention also relates to a watch case comprising at least one housing for receiving a screwed crown, and a screwed crown designed to cooperate with said housing and to close it in a sealed manner.

L'invention concerne encore une montre comportant une telle boîte de montre.The invention also relates to a watch comprising such a watch case.

L'invention concerne encore un procédé de montage, dans une boîte de montre, d'une telle couronne vissée.The invention also relates to a method of mounting, in a watch case, such a screwed crown.

Arrière-plan de l'inventionBackground of the invention

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.

Ces couronnes vissées comportent un ressort, à l'encontre duquel s'effectue le vissage. La plupart du temps ce ressort est un ressort hélicoïdal, qui porte sur une surface intérieure de la couronne, et le frottement du dernier brin de ce ressort sur cette surface entraîne de l'usure, et donc la pollution du mécanisme de la couronne, voire de la montre, par des particules d'usure, ce qu'il faut éviter.These screwed crowns include a spring, against which the screwing takes place. Most of the time this spring is a coil spring, which bears on an inner surface of the crown, and the friction of the last strand of this spring on this surface causes wear, and therefore pollution of the crown mechanism, or even of the watch, by wear particles, which must be avoided.

Résumé de l'inventionSummary of the invention

L'invention a notamment pour objectif de pallier l'inconvénient lié à l'usure occasionnée par l'extrémité du ressort, et, ainsi, de fournir une couronne vissée plus fiable que celles connues à ce jour.The object of the invention is in particular to overcome the drawback associated with the wear caused by the end of the spring, and thus to provide a screwed crown that is more reliable than those known to date.

Ainsi, l'invention concerne une couronne vissée selon la revendication 1.Thus, the invention relates to a screwed crown according to claim 1.

L'invention concerne encore une boîte de montre comportant au moins un logement pour la réception d'une couronne vissée, et une couronne vissée agencée pour coopérer avec ledit logement et l'obturer de façon étanche.The invention also relates to a watch case comprising at least one housing for receiving a screwed crown, and a screwed crown designed to cooperate with said housing and to close it in a sealed manner.

L'invention concerne encore une montre comportant une telle boîte de montre.The invention also relates to a watch comprising such a watch case.

L'invention concerne encore un procédé de montage, dans une boîte de montre, d'une telle couronne vissée.The invention also relates to a method of mounting, in a watch case, such a screwed crown.

La figure 2 montre un tel épaulement 59 à quatre faces, agencé pour coopérer avec un logement carré de la carrure. Ainsi, il n'est pas nécessaire que le tube 5 soit vissé ou chassé dans le logement 90 de la carrure 110, il est alors arrêté angulairement par cet épaulement 59, et axialement par les moyens d'arrêt axial 53. Naturellement un montage classique, chassé et/ou vissé, selon la direction axiale D, du tube 5 dans le logement 90 de la carrure 110 est également possible.More particularly, the tube 5 comprises a shoulder 59, the projection of which on a plane perpendicular to the axis of the crown D is not of revolution, and which is arranged to cooperate with a shaped housing that comprises a middle 110. The figure 2 shows such a shoulder 59 with four faces, arranged to cooperate with a square housing of the middle part. Thus, it is not necessary for the tube 5 to be screwed or driven into the housing 90 of the middle part 110, it is then stopped angularly by this shoulder 59, and axially by the axial stop means 53. Naturally a conventional assembly. , driven and / or screwed, in the axial direction D, of the tube 5 in the housing 90 of the middle 110 is also possible.

  • fixer de façon indémontable le canon fixe 3 au corps de couronne 1 ou à un composant fixé de façon indémontable au corps de couronne 1 ;
  • visser le tube 5 au canon fixe 3 en enfermant au moins un premier joint d'étanchéité 25 entre le tube 5 et le sous-ensemble 20 ;
  • préparer le tube 5 pour sa fixation dans un logement 90, et l'équiper d'au moins un deuxième joint d'étanchéité 55.
The invention also relates to a method of mounting, in a watch case, such a screwed crown 100, comprising the following steps:
  • prepare the sub-assembly 20, by inserting the support washer 9 resting on the spring 4 in the chamber 32, and resting, by its spherical cap 99, on a support surface 290 that comprises a component of the sub- set 20;
  • fixed in a non-removable manner the fixed barrel 3 to the crown body 1 or to a component fixed in a non-removable manner to the crown body 1;
