Description

  

  Dispositif de remontage automatique de mouvement d'horlogerie.    L'objet de la présente invention est un  dispositif de remontage automatique de mou  vement d'horlogerie du genre de ceux com  prenant une masse oscillante reliée par un  engrenage au ressort moteur. Ce dispositif  est caractérisé en ce que, entre deux mobiles  de cet engrenage dont l'un est relié -à la  masse et l'autre au barillet, est disposé un  ressort dont chaque extrémité est fixée à l'un  des mobiles et qui transmet le mouvement,  du premier de ceux-ci au second, tant que  le barillet n'est pas remonté à fond.  



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



  La     fig.    3 en est une vue en plan, tandis  que les     fig.    1 et 2 représentent un détail,  en coupe axiale, respectivement en plan.  



  En     fig.    3 est montré le contour d'un  mouvement de montre dont l'arbre de baril  let 17 doit être remonté automatiquement  par les oscillations d'une masse 10 tournant  autour de son axe 11; cette masse porte un       cliquet    12 qu'un ressort 13 applique contre    le rochet 14, solidaire d'une roue     dentée    15,  laquelle engrène avec la roue 2; celle-ci (voir  en particulier     fig.    1 et 2) présente une rai  nure circulaire 7 dans laquelle peut se mou  voir une cheville 6 portée par la roue 1,  laquelle peut tourner librement par rapport  à la roue 2;

   à cette dernière est fixée une  vis 8 à laquelle est reliée l'une des extré  mités d'un     ressort-lame    3 dont l'autre extré  mité est reliée à la cheville 6; la roue 1  engrène avec le rochet 16 qui porte un pi  gnon 18 engrenant lui-même avec la roue 19  fixée sur l'arbre du barillet 17.  



  Lorsque la masse 10 oscille dans le sens  de la flèche 21 en     fig.    3, elle entraîne le  rochet 14 qui fait tourner la roue 2 dans le  sens de la flèche 9. Si le ressort moteur  n'est pas suffisamment remonté, la roue 2  entraîne la roue 1 par l'intermédiaire du  ressort 3; si le ressort moteur est suffisam  ment remonté, la roue 1 reste immobile et  la roue 2 se déplace par rapport à cette  dernière, grâce à la rainure 7, en tendant le  ressort 3.      Dans certain cas, il peut se produire     chie     le diamètre de la roue dentée soit trop petit  pour permettre une bonne fixation de la gou  pille 6.

   Il suffit alors de placer celle-ci sur  un disque solidaire de     la,    roue 1, ce disque  pouvant avoir un diamètre     supérieur    à ladite  roue,' sans qu'il soit utile de le faire plus  grand que la roue 2 entre laquelle et la  roue 1 il viendrait se placer.



  Automatic winding device for a watch movement. The object of the present invention is an automatic watch movement winding device of the type comprising an oscillating mass connected by a gear to the mainspring. This device is characterized in that, between two moving parts of this gear, one of which is connected to the mass and the other to the barrel, is arranged a spring, each end of which is fixed to one of the moving parts and which transmits the movement, from the first of these to the second, as long as the barrel is not fully wound.



  The accompanying drawing represents, by way of example, an embodiment of the object of the invention.



  Fig. 3 is a plan view thereof, while FIGS. 1 and 2 show a detail, in axial section, respectively in plan.



  In fig. 3 is shown the outline of a watch movement, the barrel shaft of which 17 must be wound up automatically by the oscillations of a mass 10 rotating around its axis 11; this mass carries a pawl 12 which a spring 13 applies against the ratchet 14, integral with a toothed wheel 15, which meshes with the wheel 2; the latter (see in particular Figs. 1 and 2) has a circular groove 7 in which can be seen a pin 6 carried by the wheel 1, which can rotate freely relative to the wheel 2;

   to the latter is fixed a screw 8 to which is connected one of the ends of a leaf spring 3, the other end of which is connected to the pin 6; the wheel 1 meshes with the ratchet 16 which carries a pin 18 meshing itself with the wheel 19 fixed on the shaft of the barrel 17.



  When the mass 10 oscillates in the direction of the arrow 21 in FIG. 3, it drives the ratchet 14 which turns the wheel 2 in the direction of the arrow 9. If the mainspring is not sufficiently wound up, the wheel 2 drives the wheel 1 via the spring 3; if the mainspring is sufficiently wound up, the wheel 1 remains stationary and the wheel 2 moves relative to the latter, thanks to the groove 7, tensioning the spring 3. In certain cases, the diameter of the toothed wheel is too small to allow a good fixing of the pin 6.

   It is then sufficient to place the latter on a disc integral with the wheel 1, this disc possibly having a diameter greater than said wheel, 'without it being necessary to make it larger than the wheel 2 between which and the wheel 1 he would come and place himself.
