Description

  

   <Desc/Clms Page number 1> 
    Remontoir      automatique   pour pièce d'horlogerie L'objet de la présente invention est un remontoir automatique pour pièce d'horlogerie, muni d'une masse oscillante.    Ce   remontoir est caractérisé par le fait que cette masse forme cage et porte plusieurs mobiles du remontoir. 



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



  La fi-. 1 en est une vue en plan et les    fig.   2 et 3 sont des coupes verticales par    II-II,   respectivement 11l-111, de la    fig.   1. 



  L'axe de pivotement 1 de la masse oscillante 2 est fixé au centre du bâti du mouvement 3. Sur l'axe 1 est fixé le pignon de centre 4 qui est donc immobile et qui maintient la masse oscillante 2 en hauteur. Une bascule 17 est montée    rotativement   sur une portée de l'axe et porte un axe 6 autour duquel pivote un pignon baladeur 5. Une    ouverture   7, pratiquée dans la masse oscillante et dans laquelle s'engage l'axe du pignon, limite le déplacement angulaire de la bascule par rapport à la masse 2. 



  Suivant le sens de rotation de la masse oscillante 2, le pignon baladeur 5 engrène soit avec le mobile intermédiaire 8, soit directement avec le premier mobile 9 du train d'engrenage de réduction, qui remonte le ressort de barillet en faisant tourner le rochet 10 dans le sens de la    flèche   11. 



  Le dernier mobile 12 du train d'engrenage de réduction, commandé par le mobile 16, est placé au centre sur l'axe 1, et par son pignon 13 il engrène avec le rochet 10. Ce mobile 12 du train d'engrenage de réduction est donc le seul qui ne soit pas porté par la masse oscillante 2. 



  Le mobile 16    présente   un arbre 18 pivoté dans deux pierres dont les trous sont constitués chacun par une rainure allongée 19. Il peut occuper deux positions, l'une indiquée en traits pleins dans les fia. 1 et 3, dans laquelle sa roue engrène avec le mobile 12, et l'autre indiquée en traits mixtes, dans laquelle elle en est dégagée. Lors du remontage à main, ladite roue du mobile 16 se dégage du mobile 12 de sorte que le remontoir automatique n'est pas    entrainé.   Un ressort 20 agit sur le mobile 16 lorsque ce dernier occupe sa position débrayée de manière à le ramener contre le mobile 12. 



  La masse oscillante 2 est ajustée libre sur la portée 14 de l'axe 1, d'une part, et sur une portée 15 du pignon 13, d'autre part. Ces deux portées 14 et 15 étant relativement éloignées l'une de l'autre, assurent une bonne stabilité de la masse oscillante 2.

    Automatic winder for a timepiece The object of the present invention is an automatic winder for a timepiece, provided with an oscillating weight. This winder is characterized by the fact that this mass forms a cage and carries several winding wheels.



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



  The fi-. 1 is a plan view thereof and FIGS. 2 and 3 are vertical sections through II-II, respectively 11l-111, of FIG. 1.



  The pivot axis 1 of the oscillating mass 2 is fixed to the center of the frame of the movement 3. On the axis 1 is fixed the center pinion 4 which is therefore stationary and which maintains the oscillating mass 2 in height. A rocker 17 is rotatably mounted on a bearing surface of the axis and carries an axis 6 around which a sliding pinion 5 pivots. An opening 7, made in the oscillating mass and in which the pinion axis engages, limits displacement. angle of the rocker with respect to the mass 2.



  Depending on the direction of rotation of the oscillating weight 2, the sliding pinion 5 meshes either with the intermediate mobile 8, or directly with the first mobile 9 of the reduction gear train, which winds up the barrel spring by rotating the ratchet 10 in direction of arrow 11.



  The last mobile 12 of the reduction gear train, controlled by the mobile 16, is placed in the center on axis 1, and by its pinion 13 it meshes with the ratchet 10. This mobile 12 of the reduction gear train is therefore the only one that is not carried by the oscillating weight 2.



  The mobile 16 has a shaft 18 pivoted in two stones whose holes are each constituted by an elongated groove 19. It can occupy two positions, one indicated in solid lines in the fia. 1 and 3, in which its wheel meshes with the mobile 12, and the other indicated in phantom lines, in which it is released. During hand-winding, said wheel of the mobile 16 is released from the mobile 12 so that the automatic winding is not driven. A spring 20 acts on the mobile 16 when the latter occupies its disengaged position so as to bring it back against the mobile 12.



  The oscillating mass 2 is freely adjusted on the surface 14 of the axis 1, on the one hand, and on a surface 15 of the pinion 13, on the other hand. These two staves 14 and 15 being relatively far from each other, ensure good stability of the oscillating weight 2.
