Description

  

  Pièce d'horlogerie à remontage automatique par masse mobile.    La     présente    invention a pour objet. une  pièce d'horlogerie à remontage automatique  par masse mobile.  



  Cette pièce d'horlogerie est caractérisée  en     ce    que cette     masse    est     supportée    par au       moins    deux bras élastiques,     pivot.és    en un  même point du bâti, de manière que les       chocs    axiaux subis par la     masse    soient.     ab-          sorbés    par l'élasticité de ces bras.  



  Le dessin annexé représente, à titre       d'exemple,    une forme d'exécution de l'objet  de l'invention,     clans    laquelle seule     les    parties       nécessaires    à la compréhension de l'invention  ont été représentées.  



  La     fig.    1 est une vue en plan de la     masse     de remontage, et  la     fig.    2 est une coupe suivant 1I-11  de la     fig.    1.  



  La     masse    de remontage est constituée par       une        pièce    1 en forme de segment de cou  ronne, en métal de forte     densité,    s'étendant       saur    180 . Elle     est    fixée, par des rivets 2, à  la périphérie d'une planche 3 en forme de  secteur de cercle, et portant un canon 4 ser  vant au pivotement de la. masse sur le bâti  de la pièce d'horlogerie.

   La planche 3 est  découpée de façon que soient     formés    deux  bras 3a et 3"     disposés    symétriquement par  rapport à l'axe     géométrique    5     passant    par le  centre de rotation de la     masse    et sur     lequel          est    situé le centre de     0 ravité    de la masse.    La planche 3 étant mince, les bras     31,    et  3" sont, élastiques et absorbent les chocs  axiaux que subit la     masse    et qui     ainsi    ne dé  tériorent pas L'arbre sur lequel celle-ci est  pivotée.



  Self-winding timepiece by moving mass. The object of the present invention is. a timepiece with automatic winding by moving mass.



  This timepiece is characterized in that this mass is supported by at least two elastic arms, pivot.és at the same point of the frame, so that the axial shocks undergone by the mass are. absorbed by the elasticity of these arms.



  The appended drawing represents, by way of example, an embodiment of the subject of the invention, in which only the parts necessary for understanding the invention have been shown.



  Fig. 1 is a plan view of the reassembly mass, and FIG. 2 is a section on 11-11 of FIG. 1.



  The winding mass consists of a part 1 in the form of a crown segment, made of high density metal, extending over 180. It is fixed, by rivets 2, to the periphery of a board 3 in the form of a sector of a circle, and carrying a barrel 4 serving to pivot the. mass on the frame of the timepiece.

   The board 3 is cut in such a way that two arms 3a and 3 "are formed, arranged symmetrically with respect to the geometric axis 5 passing through the center of rotation of the mass and on which the center of 0 thrust of the mass is located. board 3 being thin, the arms 31, and 3 "are elastic and absorb the axial shocks to which the mass is subjected and which thus do not deteriorate the shaft on which the latter is pivoted.
