Description

  

  Boîte de montre étanche.    L'objet de l'invention est une boîte de  montre étanche, comprenant une     lunette-          carrure,    une glace, une calotte mobile et un  fond extérieur, caractérisée en ce que la ca  lotte mobile, prenant appui sur le fond exté  rieur, provoque par sa propre élasticité un  assemblage étanche en comprimant un joint  en matière tendre, placé entre la glace et la  calotte.  



  Le dessin montre, à titre d'exemple, une  boîte étanche suivant l'invention.  



  La     fig.    1 est une coupe par la boîte;  Les     fig.    2 et 3 sont des détails montrant  deux variantes.  



  La boîte comporte une     lunette-carrure     1 avec deux cornes et un rebord 1a, contre le  quel la glace 2 est appuyée. La lunette pré  sente un espace creux dans lequel est logée  une calotte 3 avec un fond 3a supportant le  mouvement non indiqué sur le dessin. Le  bord<B>M</B> de la calotte et celui du cadran 4  s'appuient contre un joint 8 qui repose contre  la glace 2. La lunette-carrure 1 est munie    intérieurement, sur une partie de sa hauteur,  d'un filet qui correspond au filet du bord  du fond extérieur 5. Le fond extérieur s'ap  puie contre une partie bombée du fond de  la calotte 3 et permet de presser celle-ci  contre le joint 8 et la glace 2, jusqu'à ce que  les parties intérieures soient parfaitement  étanches.  



  Un regard 7 est pratiqué dans le fond  intérieur de la calotte 3. Il sert au vissage  et dévissage de la vis de tirette. Ce regard  est obturé au moyen de la clé 9 mainte  nant un joint compressible 10. La clé 9 peut  être remplacée par une vis 11 (voir     fig.    2).  La     fig.    3 montre la fermeture du regard 7  par un tampon 12 en matière compressible  qui repose sur le fond extérieur. En tournant  le fond     extérieur,    on comprime le joint 8 et  le tampon 12 et rend le tout étanche.  



  Le fond extérieur pourrait aussi être fixé  sur la lunette-carrure ou     maintenu    sur celle-ci  au moyen de vis ou de clés.  



  La glace peut être en     matière    incassable.



  Waterproof watch box. The object of the invention is a waterproof watch case, comprising a bezel-middle, a crystal, a movable cap and an outer bottom, characterized in that the movable casing, bearing on the outer bottom, causes by its own elasticity a tight assembly by compressing a soft material seal, placed between the lens and the cap.



  The drawing shows, by way of example, a sealed box according to the invention.



  Fig. 1 is a cut by the box; Figs. 2 and 3 are details showing two variations.



  The case comprises a bezel-middle part 1 with two lugs and a rim 1a, against which the glass 2 is pressed. The bezel has a hollow space in which is housed a cap 3 with a bottom 3a supporting the movement not shown in the drawing. The edge <B> M </B> of the cap and that of the dial 4 rest against a seal 8 which rests against the crystal 2. The bezel-middle part 1 is provided internally, over part of its height, with a thread which corresponds to the thread of the edge of the outer base 5. The outer base rests against a convex part of the bottom of the cap 3 and makes it possible to press the latter against the seal 8 and the glass 2, until that the interior parts are perfectly waterproof.



  A look 7 is made in the inner bottom of the cap 3. It is used for screwing and unscrewing the pull-tab screw. This inspection window is closed by means of the key 9, maintaining a compressible seal 10. The key 9 can be replaced by a screw 11 (see fig. 2). Fig. 3 shows the closure of the viewing window 7 by a buffer 12 of compressible material which rests on the outer base. By turning the outer base, the seal 8 and the plug 12 are compressed and the whole is sealed.



  The outer case back could also be attached to the middle bezel or held onto it by means of screws or keys.



  Ice can be an unbreakable material.
