Description

  

  Montre à remontage automatique par masse mobile.    La présente invention a. pour objet une  montre à remontage automatique par masse  mobile, caractérisée par un accouplement à  friction entre la masse et un mobile trans  mettant la force au ressort moteur.  



  Le dessin annexé représente, à titre  d'exemple, une forme d'exécution de l'objet  de l'invention. On n'a représenté que les  pièces nécessaires à la compréhension de l'in  vention.  



  La     fig.    1 en est une coupe diamétrale.  La     fig.    2 en est une vue de dessus.  



  La masse mobile 1 est solidaire     d'une    ron  delle de friction 2, la rondelle 2 étant chassée  dans une ouverture 3 de la masse 1. Un pi  gnon 4, destiné à transmettre la force au res  sort moteur (non représenté) est     chassé    dans  un canon 5 présentant une saillie annulaire 6  sur laquelle appuie la rondelle 2. Un bouchon  7 est chassé dans le canon 5, sa face termi  nale venant en contact avec celle du pignon 4.  



  Un ressort de friction, ayant la forme  d'une étoile, présente une partie annulaire 8,  qui est pincée entre un rebord 9 du bouchon  7 et le canon 5, et des bras 10 qui appuient       élastiquement    sur la rondelle de friction 2.  



  Quand la masse tourne, la rondelle 2 en  traîne les bras 10 (lu ressort de friction     ci-,     par suite, le     canon    5 et le pignon 4, de sorte  que le ressort moteur s'arme. Au moment où  la montre est complètement remontée,     c'est-          à-dire    quand le ressort moteur atteint une  tension prédéterminée, la résistance à la ro  tation que présente le pignon 4 empêche le       ressort    de friction 8, 10 d'être entraîné par  la rondelle 2.

   Par suite, si la masse 1 continue    de tourner, le ressort 8, 10     res        *        ilaioiet     la     rpndelle    2 glisse sous. les bras 1 e sur la  saillie 6. On évite ainsi une surtension du  ressort moteur; et ceci sans employer, comme  ce fut généralement le cas jusqu'à présent,       des    dispositifs prenant de la place à l'inté  rieur du barillet, tels que les brides coulis  santes.  



  Il serait naturellement aussi possible de  prévoir un ressort de friction solidaire de la  masse et appuyant contre une rondelle de  friction solidaire du pignon transmettant. la  force au ressort moteur.



  Watch with automatic winding by moving mass. The present invention a. for object a watch with automatic winding by moving mass, characterized by a friction coupling between the mass and a mobile transmitting the force to the mainspring.



  The appended drawing represents, by way of example, an embodiment of the object of the invention. Only the parts necessary for understanding the invention have been shown.



  Fig. 1 is a diametral section. Fig. 2 is a top view.



  The movable mass 1 is integral with a friction washer 2, the washer 2 being driven into an opening 3 of the mass 1. A pin 4, intended to transmit the force to the motor spring (not shown) is driven into a barrel 5 having an annular projection 6 on which the washer 2 rests. A plug 7 is driven into the barrel 5, its end face coming into contact with that of the pinion 4.



  A friction spring, having the shape of a star, has an annular part 8, which is clamped between a rim 9 of the stopper 7 and the barrel 5, and arms 10 which bear elastically on the friction washer 2.



  When the mass turns, the washer 2 drags the arms 10 of it (the friction spring here-, therefore, the barrel 5 and the pinion 4, so that the mainspring is armed. When the watch is completely wound up , i.e. when the mainspring reaches a predetermined tension, the resistance to rotation exhibited by the pinion 4 prevents the friction spring 8, 10 from being driven by the washer 2.

   Consequently, if the mass 1 continues to rotate, the spring 8, 10 res * ilaioand the rpndelle 2 slips under. the arms 1 on the projection 6. This prevents overvoltage of the mainspring; and this without using, as has generally been the case until now, devices taking up space inside the barrel, such as sliding flanges.



  It would naturally also be possible to provide a friction spring integral with the mass and pressing against a friction washer integral with the transmitting pinion. the force to the mainspring.
