Description

  

      Cache-poussière    pour mouvement de montre.    L'objet     @de    la présente invention est un  cache-poussière pour mouvement de montre,  comprenant un     corps    en forme de     calotte    et  un couvercle se     fixant    entre le mouvement et  le cadran,     caractérisé    en ce que le corps en       forme    de     calotte    est maintenu séparé du cou  vercle par le mouvement.  



  Le'     dessin    ci-joint montre, à     titre    d'exem  ple, une forme d'exécution de l'objet de l'in  vention.  



  La     fig.    1 en est une vue de face;  La     fig.    2 en est un coupe     longitudinale          schématique    suivant l'axe     II-II    de la     fig.    1.  Le mouvement 1 représenté est ajusté  dans .le corps 2 du cache-poussière qui repose  sur une saillie du mouvement. La bâte du  mouvement se trouve ainsi complètement dé  gagée. Le couvercle 3 de même forme que le  mouvement s'applique exactement sur tout    son     pourtour    sur le mouvement 1. La partie       non-recouverte,    du mouvement, qui n'a au  cune ouverture sur son pourtour assure ainsi  une     fermeture    étanche à la poussière.

   Le  couvercle 3 peut être figé au     mouvement    au  moyen de     vis    ou     tenon    ou cran ou encore être       simplement    immobilisé par le cadran. Le       corps    2 et le couvercle 3 peuvent être fait en  métal ou en toute     autre-    matière suffisam  ment     rigide.  



      Dust cover for watch movement. The object of the present invention is a dust cover for watch movement, comprising a cap-shaped body and a cover securing between the movement and the dial, characterized in that the cap-shaped body is kept separate. of the neck by movement.



  The accompanying drawing shows, by way of example, one embodiment of the object of the invention.



  Fig. 1 is a front view; Fig. 2 is a schematic longitudinal section along the axis II-II of FIG. 1. The movement 1 shown is fitted in the body 2 of the dust cover which rests on a projection of the movement. The baton of movement is thus completely disengaged. The cover 3 of the same shape as the movement is applied exactly over its entire periphery on the movement 1. The uncovered part of the movement, which does not have any opening on its periphery, thus ensures a dust-tight seal.

   The cover 3 can be fixed during movement by means of screws or tenon or notch or else simply be immobilized by the dial. The body 2 and the cover 3 can be made of metal or any other sufficiently rigid material.
