Description

  

      Dispositif        anti-poussière    pour organe de     manaeuvre     traversant la paroi d'une     boîte    de montre    Il existe déjà des dispositifs pour empêcher  l'introduction de la poussière ou d'autres petits  corps étrangers dans la boîte de montre, par       exempld    par le trou de la tige de remontoir,  particulièrement lorsque celle-ci est     tirée    vers  l'extérieur pour la mise à l'heure<B>;</B> à ce moment,  il existe un espace vide annulaire entre cette  tige et le trou pratiqué dans la boîte pour son  passage.  



  Ces dispositifs comprennent en général une  bague et un ressort logés dans une creusure  de la couronne de la tige de remontoir, le res  sort tendant à pousser la bague contre la boîte,  ces deux pièces, bague et ressort, étant mainte  nues dans la couronne, par une rondelle ou un  sertissage au bas de la     creusure    de celle-ci ;     ces     dispositifs présentent l'inconvénient d'être soli  daires de la couronne.  



  La présente invention, qui peut     s'appliquer     non seulement à un remontoir, mais aussi à des  poussoirs, par exemple de chronographes ou de  calendriers ou à d'autres organes     traversant    par  une tige une paroi d'une boîte de montre, a  pour but de remédier à cet inconvénient.

   Elle  comprend une bague entourant la tige de l'or  P<I>a</I>     ne        de        man#uvre        et        qu'un        ressort        tend   <B>à</B>     ap        -          pliquer    contre la boîte ; elle est caractérisée par    le fait que l'extrémité inférieure du ressort est  fixée à la bague de façon que ces deux pièces  forment un tout.  



  Le dessin ci-annexé représente, à titre  d'exemple, une forme d'exécution de l'objet de  la présente invention appliquée à une couronne  de remontoir.  



       L'unique    figure du dessin en est une coupe  partielle par l'axe de la tige de     remontoir.     



  1 est une bague présentant, au fond de sa  creusure 2, une     rainure    circulaire 3 ; dans     celle-          ci    s'engage la première spire 4 du ressort  boudin conique 5. La     dernière    spire 6 de ce  ressort passe librement sur le canon 7 de la  couronne 8 et appuie contre le fond 9 de la  creusure 10. La tige de remontoir 11, qui est  vissée dans la couronne 8, passe au travers du  trou 12 pratiqué dans la boîte de la montre 13.  



  Bien entendu, la fixation du     ressort    à la  bague pourrait se faire d'une autre façon, par  exemple, par soudure, par sertissage, au moyen  d'une vis, etc...



      Anti-dust device for an actuator passing through the wall of a watch case There are already devices to prevent the introduction of dust or other small foreign bodies into the watch case, for example through the hole in the watch case. winding stem, particularly when it is pulled outwards to set the time <B>; </B> at this time, there is an annular empty space between this stem and the hole made in the case for its passage.



  These devices generally include a ring and a spring housed in a recess in the crown of the winding stem, the spring tending to push the ring against the case, these two parts, ring and spring, being held in the crown, by a washer or a crimp at the bottom of the recess thereof; these devices have the drawback of being integral with the crown.



  The present invention, which can be applied not only to a winder, but also to pushers, for example of chronographs or calendars or to other organs passing through a stem through a wall of a watch case, aims to remedy this drawback.

   It comprises a ring surrounding the rod of the gold P <I> a </I> not to maneuver and a spring tends <B> to </B> to apply against the case; it is characterized by the fact that the lower end of the spring is fixed to the ring so that these two parts form a whole.



  The appended drawing represents, by way of example, an embodiment of the object of the present invention applied to a winding crown.



       The only figure in the drawing is a partial section through the axis of the winding stem.



  1 is a ring having, at the bottom of its recess 2, a circular groove 3; in this engages the first turn 4 of the conical coil spring 5. The last turn 6 of this spring passes freely over the barrel 7 of the crown 8 and presses against the bottom 9 of the recess 10. The winding stem 11 , which is screwed into the crown 8, passes through the hole 12 made in the watch case 13.



  Of course, the fixing of the spring to the ring could be done in another way, for example, by welding, by crimping, by means of a screw, etc ...
