Description

  

      Remontoir        automatique    pour mouvement d'horlogerie    L'objet de la présente invention est un re  montoir automatique pour mouvement d'horlo  gerie, comprenant une masse oscillant autour  d'un axe et solidaire d'un pignon coaxial. Ce  remontoir est caractérisé par une bascule mon  tée     rotativement    autour dudit axe et portant un  renvoi unique, lequel engrène constamment  avec ledit pignon et peut engrener, suivant les  mouvements de la bascule, avec l'un ou l'au  tre des deux premiers mobiles du rouage qui  aboutit au barillet.  



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



  La     fig.    1 en est une vue en plan schémati  que.  



  La     fig.    2 est une coupe par<I>11-11</I> de la     fig.    1.  Au dessin, 1 représente le barillet moteur  du mouvement monté entre la platine 2 et le  pont de barillet 3. Sur l'arbre 4 de ce barillet  sont fixés le rochet 5, relié au remontoir à  main non représenté et le rochet 6, auquel  aboutit le rouage du remontoir automatique,  lequel rouage comprend les trois mobiles 7, 8  et 9, ce dernier étant constitué uniquement par  une roue.  



  La masse 10 du remontoir automatique  peut tourner autour de l'axe 11 fixé dans la  platine 12 de ce remontoir. Elle présente un    logement dans lequel est chassé le pignon 13  qui tourne aussi autour de l'axe 11. Sur celui-ci,  est également montée,     rotativement,    la bascule  14 disposée entre la platine 12 et le pignon 13  qui, ainsi que la masse, repose librement sur  elle. Cette bascule 14 porte un renvoi unique  15 qui engrène constamment avec le pignon 13  et qui, suivant la position de la bascule 14, en  grène avec l'un ou l'autre des mobiles 8 et 9.  Les oscillations de ce renvoi sont     limitées    par  une cheville 16 pouvant se déplacer dans une  ouverture en arc de cercle 17 du pont 18 du  remontoir automatique.  



  Lorsque la masse oscille dans le sens de la  flèche     f    en     fig.    1, le renvoi 15 est en prise avec  le mobile 8 comme représenté. Si la masse  oscille en sens inverse,     l'effort    tangentiel pro  voqué par la rotation du pignon 13 sur le ren  voi 15 va     entraîner    la bascule 14 jusqu'au mo  ment où ce renvoi sera en prise avec le mobile  9 qu'il fera tourner ; le frottement du pignon 13  sur la bascule 14 contribuera à cet     entraine-          ment.    Le renvoi 15 restant toujours à égale dis  tance de l'axe du pignon 13, la pénétration des  dents de ce renvoi dans ce pignon ne varie pas.



      Automatic winder for a clockwork movement The object of the present invention is an automatic winder for a clockwork movement, comprising a mass oscillating about an axis and secured to a coaxial pinion. This winder is characterized by a rocker mounted to rotate around said axis and carrying a single reference, which constantly meshes with said pinion and can mesh, according to the movements of the rocker, with one or the other of the first two moving parts of the cog that ends in the barrel.



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



  Fig. 1 is a schematic plan view thereof.



  Fig. 2 is a section through <I> 11-11 </I> of FIG. 1. In the drawing, 1 represents the motor barrel of the movement mounted between the plate 2 and the barrel bridge 3. On the shaft 4 of this barrel are fixed the ratchet 5, connected to the hand winder not shown and the ratchet 6, which ends with the automatic winding wheel, which wheel comprises the three moving parts 7, 8 and 9, the latter being formed solely by a wheel.



  The mass 10 of the automatic winder can rotate around the axis 11 fixed in the plate 12 of this winder. It has a housing in which is driven the pinion 13 which also rotates around the axis 11. On the latter, is also mounted, rotatably, the lever 14 disposed between the plate 12 and the pinion 13 which, as well as the mass , rests freely on it. This rocker 14 carries a single reference 15 which constantly meshes with the pinion 13 and which, depending on the position of the lever 14, grained with one or the other of the mobiles 8 and 9. The oscillations of this reference are limited by a pin 16 able to move in an arcuate opening 17 of the bridge 18 of the automatic winder.



  When the mass oscillates in the direction of the arrow f in fig. 1, the return 15 is engaged with the mobile 8 as shown. If the mass oscillates in the opposite direction, the tangential force produced by the rotation of the pinion 13 on the drive 15 will drive the rocker 14 until the moment when this drive is engaged with the mobile 9 that it will rotate. ; the friction of the pinion 13 on the rocker 14 will contribute to this drive. The transmission 15 always remaining at an equal distance from the axis of the pinion 13, the penetration of the teeth of this transmission in this pinion does not vary.
