Description

  

  <B>Mécanisme de remontage</B>     automatique   <B>pour montres.</B>    L'objet de l'invention est un mécanisme  de remontage automatique à masse oscillante  pour     montres,    caractérisé en ce     que    la<B>,</B>     masse     est solidaire d'un pignon coaxial engrenant  de part et     d'autre    à gauche et à     droite    dans  des pignons montés dans une bascule pouvant  osciller autour du pivot de la masse, l'un ou  l'autre des.     pignons    de la bascule transmet  tant, .suivant le sens     d'oscillation    de la masse,  le mouvement au ressort-moteur par un train  d'engrenages.  



  Le dessin ci-joint montre schématique  ment à titre d'exemple une forme d'exécution  de l'objet de l'invention.  



  La     fig.    1 montre le     mécanisme    dans sa  position     moyenne.     



  Les     fig.2    et 3 montrent les,     positions     l'engrènement.  



  Le mécanisme de remontage     automatique     pour montres comporte un pignon 1 coaxial  et solidaire d'une masse oscillante 2     (fig.    1),  oscillant autour de l'axe 3. De part et d'autre  à gauche et à droite du     pignon.    1 sont dis  posés les pignons 4 et 5 qui sont en prise  directe avec le pignon 1. Les pignons 4 et 5  sont montes dans une bascule 6 pivotant  autour de l'axe 3.     Le    pignon de renvoi 7,  la roue 8, le pignon 9 et la roue 10 cons  tituent le train d'engrenages pour remonter  le     ressort-moteur.     



  Le remontage du     ressort-moteur    se fait  par l'oscillation de la     masse    comme suit: Si    la masse oscille à gauche suivant la flèche 11  de la     fig.    2, la bascule provoque l'engrène  ment .entre les     pignons    4 et 7; si la masse  oscille par contre à droite suivant la flèche 13  de la     fig.    3, le pignon 5 engrène directement  avec la roue 8, l'entraînant dans     le        sens     de la flèche 12.  



       Les        pignons    de la bascule peuvent être  du même diamètre.  



  Le mouvement     alternatif    de la bascule  est obtenu uniquement par les     efforts    tan  gentiels. appliqués dans les deux sens aux  pignons qu'elle     porte    par la     denture    du .  pignon solidaire de la masse.



  <B> Automatic <B> winding mechanism </B> for watches. </B> The subject of the invention is an automatic winding mechanism with oscillating weight for watches, characterized in that the <B>, < / B> mass is integral with a coaxial pinion meshing on either side to the left and to the right in pinions mounted in a rocker capable of oscillating around the pivot of the mass, one or the other of. The pinions of the rocker transmits as much, following the direction of oscillation of the mass, the movement to the mainspring by a train of gears.



  The accompanying drawing shows schematically by way of example an embodiment of the object of the invention.



  Fig. 1 shows the mechanism in its middle position.



  Figs. 2 and 3 show the meshing positions.



  The automatic winding mechanism for watches comprises a pinion 1 coaxial and integral with an oscillating mass 2 (fig. 1), oscillating about the axis 3. On either side to the left and to the right of the pinion. 1 are arranged the pinions 4 and 5 which are in direct engagement with the pinion 1. The pinions 4 and 5 are mounted in a rocker 6 pivoting around the axis 3. The idler pinion 7, the wheel 8, the pinion 9 and wheel 10 constitute the gear train for winding up the mainspring.



  The motor spring is reassembled by the oscillation of the mass as follows: If the mass oscillates to the left according to arrow 11 in fig. 2, the rocker causes meshing. Between the pinions 4 and 7; if the mass oscillates on the other hand to the right according to the arrow 13 of FIG. 3, pinion 5 meshes directly with wheel 8, driving it in the direction of arrow 12.



       The pinions of the rocker can be of the same diameter.



  The reciprocating movement of the rocker is obtained only by the tangential forces. applied in both directions to the pinions it carries by the teeth of the. pinion integral with the mass.
