Description

  

  Pièce d'horlogerie à remontage automatique par masse oscillante.    La présente invention a pour objet une  pièce  < l'horlogerie à. remontage     automatique     par masse oscillante; cette pièce d'horlogerie  est, caractérisée par le fait que la     masse    de       reiuontage    est. supportée par un bras élas  tique non rectiligne et conformé de faon     ù,     amortir les chocs radiaux que subit la masse.  



  Le     dessin    annexé     représente,    à. titre  d'exemple, une forme d'exécution de l'objet  de l'invention et deux variantes.  



  La     fig.    1 est -une vue en plan d'une pièce  d'horlogerie, et  les     fig.    2 et 3 sont des vues en plan -de dé  tails des deux variantes.  



  La pièce d'horlogerie représentée com  prend une masse     oscillante    de remontage 1.  supportée par un bras élastique mince 2, des  tiné à amortir les chocs axiaux que petit subir  la masse; ce bras 2 est     solidaire    d'un pignon 3  engrenant avec un secteur denté 4. Ce der  nier porte un cliquet 5 coopérant avec le  rochet 6 du barillet. Deux ressorts amortis  seurs 7     limitent    les oscillations de la     masse.     Le bras élastique 2 n'est pas rectiligne, mais  s'étend en zigzag de façon à amortir les chocs  radiaux que subit la     masse.    Ce bras est venu  d'une pièce avec la masse ou avec le support  de masse.

      Dans la variante de la     fig.    2, le bras élas  tique désigné par 8 a la. forme d'un     U,    tandis  que dans la forme d'exécution de la     fig.        33,     le bras élastique 9     est        curviligne.  



  Self-winding timepiece by oscillating weight. The present invention relates to a part <watchmaking. automatic winding by oscillating weight; this timepiece is characterized by the fact that the reiuontage mass is. supported by a non-rectilinear elastic arm and shaped so as to absorb the radial shocks to which the mass is subjected.



  The accompanying drawing represents, to. by way of example, one embodiment of the object of the invention and two variants.



  Fig. 1 is a plan view of a timepiece, and FIGS. 2 and 3 are detailed plan views of the two variants.



  The timepiece shown com takes a winding oscillating mass 1. supported by a thin elastic arm 2, designed to absorb the axial shocks that the mass undergoes; this arm 2 is integral with a pinion 3 meshing with a toothed sector 4. This latter carries a pawl 5 cooperating with the ratchet 6 of the barrel. Two damped springs 7 limit the oscillations of the mass. The elastic arm 2 is not rectilinear, but extends in a zigzag fashion so as to damp the radial shocks to which the mass is subjected. This arm came in one piece with the mass or with the mass support.

      In the variant of FIG. 2, the elastic arm designated by 8 a la. U-shaped, while in the embodiment of FIG. 33, the elastic arm 9 is curvilinear.
