Description

  

  Dispositif de remontage automatique de pièce d'horlogerie.    ha     présente    invention a .pour objet un  dispositif de remontage automatique de pièce       d'horlogerie    comprenant une masse     oscillante     reliée au     ressort    moteur par l'intermédiaire  d'un     mécanisme    de     transmission    du mouve  ment, caractérisé en. ce que ce mécanisme de       transmission    comprend une came, faisant.

         corps    avec .la masse oscillante, et     sur    laquelle  vient buter un levier monté d     e    façon     oscil-          lante,    qui est muni d'un cliquet     d'impulsion     en prise avec une roue à rochet solidaire d'un       pignon    de     rem@-antage    du ressort moteur, le       tout    agencé de telle façon que, lors du dépla  cement dans un sens ou dans l'autre de la  masse oscillante, ledit pignon est entraîné par  l'intermédiaire du levier oscillant.  



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



  La     fig.    1 en est une vue en plan, et.  



  la     fig.    2 une coupe suivant la     ligne    brisée       A-A'.     



  Sur le bâti du mouvement de la pièce  d'horlogerie est monté un tourillon fixe 2 sur  lequel     tourne    librement la masse oscillante 1  solidaire de la canne 3 qui a. la forme d'une  étoile. Sur l'axe 7 tournant entre les ponts 13  et 13' constituant le bâti est     ajusté    fou le  levier oscillant 4 dont l'extrémité vient buter       sur        @la    came 3 sous l'effet du     ressort    8 monté  sur le bâti. Sur ce dit levier oscillant. 4 est  fixé avec son ressort. 9 le cliquet d'impulsion  10 en prise avec la roue à rochet 6 montée  sur l'axe 7 avec le pignon 5 qui remonte par    un train d'engrenages non représenté le res  sort moteur du mouvement.

   Un deuxième     cli-          quet    dit de retenue 11, pressé par le ressort  12 monté sur le bâti 1.3, reste en prise avec  la roue à rochet 6 et l'oblige à ne tourner que  dans le sens du remontage.  



  La came 3 en forme :d'étoile peut être rem  placée par une came constituée par une série  de     tétons    montés sur la     masse    oscillante 1,  concentriquement autour du point de rotation  de ladite masse,     tétons    sur lesquels vient buter  l'extrémité du levier oscillant 4.  



  Lorsque la masse 1 se meut     dans    un sens  ou .dans l'autre, la came 3 fait osciller le le  vier 4, lequel, par son cliquet d'impulsion 10,  pousse la. roue à rochet 6, entraînant avec elle  le pignon 5.  



  Le principal avantage du mécanisme dé  crit réside en ce que les     pièces    qui le com  pose sont peu nombreuses, ce qui simplifie  la     construction.  



  Automatic winding device for a timepiece. The present invention relates to an automatic device for winding a timepiece comprising an oscillating weight connected to the mainspring via a movement transmission mechanism, characterized in. what this transmission mechanism includes a cam, doing.

         body with the oscillating mass, and on which abuts a lever mounted in an oscillating manner, which is provided with an impulse pawl engaged with a ratchet wheel integral with a sprocket for replacing the spring motor, the whole arranged in such a way that, during the displacement in one direction or the other of the oscillating mass, said pinion is driven by means of the oscillating lever.



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



  Fig. 1 is a plan view, and.



  fig. 2 a cut along the broken line A-A '.



  On the frame of the movement of the timepiece is mounted a fixed journal 2 on which freely rotates the oscillating mass 1 integral with the rod 3 which has. the shape of a star. On the axis 7 rotating between the bridges 13 and 13 'constituting the frame is adjusted for the oscillating lever 4, the end of which abuts on @la cam 3 under the effect of the spring 8 mounted on the frame. On this said oscillating lever. 4 is fixed with its spring. 9 the impulse pawl 10 in engagement with the ratchet wheel 6 mounted on the axis 7 with the pinion 5 which goes up by a gear train not shown, the res exits the movement.

   A second so-called retaining pawl 11, pressed by the spring 12 mounted on the frame 1.3, remains in engagement with the ratchet wheel 6 and forces it to turn only in the winding direction.



  The cam 3 in the form of a star can be replaced by a cam formed by a series of studs mounted on the oscillating mass 1, concentrically around the point of rotation of said mass, studs on which the end of the oscillating lever abuts 4.



  When the mass 1 moves in one direction or the other, the cam 3 oscillates the lever 4, which, by its impulse pawl 10, pushes it. ratchet wheel 6, pulling pinion 5 with it.



  The main advantage of the mechanism described lies in that the parts which compose it are few, which simplifies the construction.
