Description

La présente invention concerne les boîtes de montres, et elle concerne plus précisément une boîte de montre comprenant une carrure-lunette sur laquelle sont montés de façon amovible un fond et une glace, et dans laquelle un mouvement peut être positionné au moyen d'un cercle d'encageage.The present invention relates to watch cases, and more specifically it relates to a watch case comprising a middle-bezel on which are removably mounted a base and a crystal, and in which a movement can be positioned by means of a circle casing.

L'objet de l'invention est de proposer une construction de boîtes de montres de faible épaisseur, munies de moyens de fixation du fond et de la glace de très faible encombrement, et dont l'aspect plat est encore renforcé par la possibilité d'utiliser une carrure-lunette de forme, recevant un cadran et une glace de grandes dimensions, alors que le fond peut être circulaire et de petites dimensions de manière à ne pas s'étendre jusqu'aux bords de la partie inférieure de la carrure-lunette.The object of the invention is to provide a construction of watch boxes of small thickness, provided with means for fixing the bottom and glass of very small size, and whose flat appearance is further reinforced by the possibility of use a shaped bezel, receiving a large dial and crystal, while the bottom may be circular and of small dimensions so as not to extend to the edges of the lower part of the bezel .

A cet effet, la boîte de montre définie dans les revendications de la demande met notamment en oeuvre un fond maintenu à la partie inférieure de la carrure au moyen de vis de fixation, l'ancrage de ces vis et les configurations respectives de la carrure-lunette et du cercle d'encageage étant déterminées de façon que le serrage des vis assure simultanément la fixation du fond et le blocage du cercle d'encageage, ce dernier pouvant également participer à la compression de joints d'étanchéité, au positionnement de la glace, et dans certains modes de réalisation particuliers à son immobilisation.To this end, the watch case defined in the claims of the application implements in particular a bottom maintained at the lower part of the middle by means of fixing screws, the anchoring of these screws and the respective configurations of the middle. bezel and casing circle being determined so that the tightening of the screws simultaneously secures the bottom and the blocking of the casing circle, the latter can also participate in the compression of seals, in the positioning of the glass , and in certain embodiments specific to its immobilization.

L'invention sera bien comprise à la lecture de la description suivante, faite en liaison avec les dessins joints, parmi lesquels :

  • - la figure 1 est une vue de dessus d'une boîte de montre selon un mode de réalisation de l'invention, dont la glace et le mouvement ont été retirés;
  • - la figure 2 est une vue partielle en coupe selon la ligne II-II de la boîte de montre de la figure 1;
  • - la figure 3 est une vue analogue à celle de la figure 2 d'un deuxième mode de réalisation de l'invention.
The invention will be clearly understood on reading the following description, made in conjunction with the accompanying drawings, among which:
  • - Figure 1 is a top view of a watch case according to an embodiment of the invention, from which the crystal and the movement have been removed;
  • - Figure 2 is a partial sectional view along line II-II of the watch case of Figure 1;
  • - Figure 3 is a view similar to that of Figure 2 of a second embodiment of the invention.

Comme on le voit dans la figure 1, une boîte de montre selon un premier mode de réalisation de l'invention comporte une carrure-lunette 1, par exemple de forme, qui présente une ouverture supérieure 2 et une ouverture inférieure 3 de plus faibles dimensions., L'ouverture supérieure 2 est de préférence de forme, et elle est destinée à être obturée par une glace non représentée, engagée latéralement dans des organes de butée 4 formant des glissières s'étendant sur deux bords opposés de la carrure-lunette 1. L'ouverture inférieure 3, de préférence circulaire et de diamètre réduit, est obturée par le fond 5. Un cercle d'encageage 6 est mis en place dans la boîte par l'ouverture supérieure 2 de la carrure.As can be seen in FIG. 1, a watch case according to a first embodiment of the invention comprises a middle-bezel 1, for example of shape, which has an upper opening 2 and a lower opening 3 of smaller dimensions ., The upper opening 2 is preferably in shape, and it is intended to be closed by a glass (not shown), engaged laterally in abutment members 4 forming slides extending on two opposite edges of the middle part 1 The lower opening 3, preferably circular and of reduced diameter, is closed off by the bottom 5. A casing ring 6 is placed in the case by the upper opening 2 of the middle part.

La coupe de la figure 2 montre que l'ouverture inférieure 3 de la carrure 1 est définie par une projection 7 s'étendant radialement vers l'intérieur, et contre la surface inférieure 8 de laquelle est maintenu le fond 5 au moyen de vis de fixation 9.The section of FIG. 2 shows that the lower opening 3 of the middle part 1 is defined by a projection 7 extending radially inwards, and against the lower surface 8 of which the base 5 is held by means of screws. fixing 9.

Le cercle 6 présente une portion supérieure 10 et une portion inférieure 11, comprenant des surfaces extérieures 12 et 13 dont les dimensions correspondent respectivement à celles des ouvertures supérieure 2 et inférieure 3 de la carrure-lunette 1, sa portion inférieure 11 venant s'engager dans l'ouverture inférieure 3.The circle 6 has an upper portion 10 and a lower portion 11, comprising outer surfaces 12 and 13 whose dimensions correspond respectively to those of the upper 2 and lower 3 openings of the middle part 1, its lower portion 11 engaging. in the lower opening 3.

Dans le mode de réalisation représenté, dans lequel la glace 14 est maintenue à la partie supérieure de la carrure-lunette 1 par des organes de butée 4 formant une glissière qui l'empêche de s'échapper vers le haut, la partie supérieure 10. du cercle 6 présente une première surface d'appui 15 pour solliciter la périphérie de la glace 4 contre les organes de butée 4, tandis que sa portion inférieure 11 comporte une deuxième surface d'appui 16 qui vient au contact du fond 5. Les vis de fixation 9 du fond 5, accessibles de l'extérieur de la boîte, sont engagées dans des taraudages 17 de la carrure-lunette 1, de telle manière que leur serrage, après mise en place du fond, provoque, par l'intermédiaire de l'action du fond sur la surface d'appui 16 du cercle, un déplacement de celui-ci en direction de la glace, jusqu'au moment ou sa surface d'appui 15 vient s'appuyer, directement ou de préférence par l'intermédiaire d'un joint d'étanchéité 18, contre la périphérie inférieure de la glace 14 pour la plaquer contre les organes de butée 4. Un réhaut 19 est placé sur le cadran 20 pour masquer le joint d'étanchéité 18, dont l'invisibilité par le dessus de la boîte peut être garantie de façon connue en soi par une couche de métallisation déposée sous la glace. Un deuxième joint d'étanchéité 21 peut être disposé entre le fond 5 et la portion inférieure 11 du cercle 6, à côté de la deuxième surface d'appui 16 de ce dernier, par exemple.In the embodiment shown, in which the crystal 14 is held at the upper part of the middle part 1 by stop members 4 forming a slide which prevents it from escaping upwards, the upper part 10. of the circle 6 has a first bearing surface 15 for urging the periphery of the glass 4 against the stop members 4, while its lower portion 11 comprises a second bearing surface 16 which comes into contact with the bottom 5. The screws fixing 9 of the base 5, accessible from the outside of the case, are engaged in threads 17 of the middle part-bezel 1, in such a way that their tightening, after placement of the bottom, causes, by means of the action of the bottom on the bearing surface 16 of the circle, a displacement of the latter in the direction of the glass, until the moment when its bearing surface 15 comes to bear, directly or preferably by the through a seal 18, against the lower periphery of the glass 14 p or press it against the stop members 4. A flange 19 is placed on the dial 20 to hide the seal 18, the invisibility of which from above the box can be guaranteed in a manner known per se by a layer of metallization deposited under the ice. A second seal 21 may be disposed between the bottom 5 and the lower portion 11 of the circle 6, next to the second bearing surface 16 of the latter, for example.

L'emboîtage du mouvement 22 est aisé et s'exécute de la manière suivante : le cercle 6 et le mouvement 22 sont introduits dans la carrure-lunette 1 par son ouverture supérieure 2, puis le joint 18 et le réhaut 19 sont mis en place, avant que la glace 14 soit engagée latéralement dans ses glissières. Il suffit alors de fixer le fond 5, après mise en place du joint 21, au moyen des vis 9 dont le serrage provoque simultanément l'application du fond 5 contre la surface inférieure 23 de la projection 7, le blocage du cercle 6, celui de la glace 14 et la compression des joints d'étanchéité 18 et 19. Le démontage de la boîte s'opère de la manière inverse, et il suffit, pour permettre le retrait de la glaçe, de veiller à ce qu'un espace de hauteur h soit disponible à l'état assemblé de la boîte entre la portion supérieure 10 du cercle 6 et la projection 7 de la carrure, pour permettre lors du démontage du fond, un déplacement du cercle suffisant pour relâcher la pression qu'il exerce sur la glace.The casing of the movement 22 is easy and is carried out as follows: the circle 6 and the movement 22 are introduced into the middle part of the bezel 1 through its upper opening 2, then the seal 18 and the flange 19 are put in place , before the glass 14 is engaged laterally in its slides. It then suffices to fix the bottom 5, after fitting the seal 21, by means of the screws 9, the tightening simultaneously causes the application of the bottom 5 against the lower surface 23 of the projection 7, the blocking of the circle 6, that of the glass 14 and the compression of the seals 18 and 19. The disassembly of the box takes place inversely, and it suffices, to allow the ice to be removed, to ensure that a space of height h is available in the assembled state of the box between the upper portion 10 of the circle 6 and the projection 7 of the middle part, to allow during disassembly of the back, a displacement of the circle sufficient to release the pressure it exerts on the ice.

Dans la figure 3, on a représenté un deuxième mode de réalisation d'une boîte de montre selon l'invention, dans lequel les vis 9 sont engagées dans des taraudages 17 pratiqués cette fois dans le cercle 6 lui-même, de façon que leur serrage provoque l'application d'une surface inférieure 25 de sa portion supérieure 10 contre la surface supérieure en regard, 26, de la projection 7. De préférence les surfaces inférieures 8 de la projection 7 et 27 du cercle 6 viennent alors dans le prolongement l'une de l'autre. Un joint d'étanchéité annulaire, large, 28, comportant des passages 29 pour les vis 9 est disposé entre les surfaces 8 et 27 d'une part, et la surface en regard du fond d'autre part.In Figure 3, there is shown a second embodiment of a watch case according to the invention, in which the screws 9 are engaged in threads 17 made this time in the circle 6 itself, so that their tightening causes the application of a lower surface 25 of its upper portion 10 against the opposite upper surface, 26, of the projection 7. Preferably the lower surfaces 8 of the projection 7 and 27 of the circle 6 then come in the extension one from the other. A wide annular seal, 28, having passages 29 for the screws 9 is disposed between the surfaces 8 and 27 on the one hand, and the facing surface on the other hand.

La glace 14 est chassée de façon connue dans l'ouverture supérieure 2 de la carrure-lunette 1, avec interposition d'un joint d'étanchéité 30 en 1. Le réhaut 31 fait office d'entretoise entre la glace 14 et le cercle 6.The lens 14 is driven in a known manner into the upper opening 2 of the middle part 1, with the interposition of a seal 30 in 1. The flange 31 acts as a spacer between the lens 14 and the circle 6 .

L'emboîtage est réalisé en introduisant le cercle 6 et le mouvement 22 dans la carrure-lunette 1 par son ouverture supérieure 2, puis le fond est appliqué contre la surface inférieure 8 de la projection 7 en serrant les vis 9, après mise en place du joint 28, de manière à bloquer simultanément le fond 5 et le cercle d'encageage 6. Ensuite, le réhaut 31 est placé sur le cadran 20 et la glace 14 est alors chassée dans l'ouverture 2. Pour démonter la montre, il suffit de retirer le fond 5 et la tige de remontoir, puis de déchasser la glace 14 en exerçant une poussée sur la partie inférieure du cercle 6 par l'intermédiaire d'une potence classique, cette poussée étant transmise à la glace 14 par l'intermédiaire du réhaut 31.The casing is produced by introducing the circle 6 and the movement 22 into the middle-bezel 1 through its upper opening 2, then the base is applied against the lower surface 8 of the projection 7 by tightening the screws 9, after fitting the seal 28, so as to simultaneously block the bottom 5 and the casing ring 6. Then, the flange 31 is placed on the dial 20 and the glass 14 is then removed in the opening 2. To dismantle the watch, it suffices to remove the case 5 and the winding stem, then release the crystal 14 by pushing on the lower part of the circle 6 via a conventional stem , this thrust being transmitted to the ice 14 via the flange 31.

Il est clair que les constructions décrites ci-dessus, en permettant notamment de réaliser des boîtes présentant une ouverture supérieure de grandes dimensions, alors que celles de l'ouverture inférieure restent limitées, autorisent une réduction correspondante des dimensions du fond, dont les bords ainsi que les vis de fixation peuvent alors être repoussés vers le centre de la boîte, et se trouvent ainsi plus facilement dissimulés du regard.It is clear that the constructions described above, in particular making it possible to produce boxes having an upper opening of large dimensions, while those of the lower opening remain limited, allow a corresponding reduction in the dimensions of the bottom, the edges of which thus that the fixing screws can then be pushed back towards the center of the box, and are thus more easily hidden from view.

Bien qu'elle ait été décrite en référence à deux modes de réalisation particuliers, l'invention ne s'y trouve nullement limitée, mais est au contraire susceptible de nombreuses modifications et variantes qui apparaîtront à l'homme du métier.Although it has been described with reference to two particular embodiments, the invention is in no way limited thereto, but is on the contrary liable to numerous modifications and variants which will appear to those skilled in the art.
