Description

  

   <Desc/Clms Page number 1> 
 Mécanisme de remontage et de    mise   à l'heure à tirette, pour pièce d'horlogerie L'objet de la présente invention est un mécanisme de remontage et de mise à l'heure à tirette, pour    pièce   d'horlogerie, dans lequel la tirette    est   montée sur un arbre disposé dans le bâti. 



  Ce    mécanisme   est caractérisé par le    fait   que    cet   arbre peut tourner autour de son axe,    mais   non pas    coulisser   le long de    celui-ci,   et présente un filetage sur lequel est vissée la tirette,    l'extrémité   avant de cet arbre traversant le    cadran,   le tout dans le but que, en agissant sur cette extrémité, on puisse, en faisant    tourner   l'arbre, engager la tirette avec la tige de remontage ou l'en dégager. 



  Le dessin représente, à titre d'exemple, et partiellement une    forme   d'exécution de l'objet de la présente invention. 



  La    fig.   1 est une vue de face de la tirette et de la partie de la tige de remontoir avec    laquelle   elle travaille ; les    fig.   2 et 3 sont deux    coupes   par    II-II   de la    fig.   1 montrant deux phases différentes du fonctionnement. 



  La forme d'exécution représentée comprend une platine 1 sur laquelle sont fixés d'un côté les ponts 2 et, de l'autre, le cadran 3. 4 est la tige de remontoir dans une gorge 5 de laquelle pénètre    le   plot 6 de la tirette 7. 8 est un arbre monté dans le bâti de façon à pouvoir tourner autour de son axe, mais non    pas   coulisser le long de    celui-ci   ;    il   présente un pas de vis 9 sur lequel est vissée la tirette 7 ;

   son    extré-      mité   avant 10 traverse le cadran dans une    ouverture   11 et présente une fente 12. 13 est le sautoir usuel déterminant les positions de remontage et de    mise   à l'heure de la tirette et 14    est   un    ressort   tendant à maintenir le plot 6 dans la gorge 5. 



  La    fig.   2 montre la tirette en prise avec la tige de remontoir ; pour l'en dégager    il   suffit, en utilisant la fente 12, de    faire   tourner, dans le sens voulu, l'arbre 8. La tirette -se    déplace   alors le long de    l'arbre   en s'éloignant de la tige ; si l'on    tourne   en    sens   inverse l'arbre 8, elle s'en rapproche.

 Pull-down winding and time-setting mechanism, for a timepiece The object of the present invention is a pull-up winding and time-setting mechanism, for a timepiece, in which the pull tab is mounted on a shaft arranged in the frame.



  This mechanism is characterized by the fact that this shaft can rotate around its axis, but not slide along it, and has a thread onto which the pull tab is screwed, the front end of this shaft passing through the dial, the whole in order that, by acting on this end, one can, by turning the shaft, engage the pull-tab with the winding rod or release it.



  The drawing shows, by way of example, and partially an embodiment of the object of the present invention.



  Fig. 1 is a front view of the zipper and of the part of the winding stem with which it works; figs. 2 and 3 are two sections through II-II of FIG. 1 showing two different phases of operation.



  The embodiment shown comprises a plate 1 on which are fixed on one side the bridges 2 and, on the other, the dial 3. 4 is the winding stem in a groove 5 which penetrates the stud 6 of the zipper 7. 8 is a shaft mounted in the frame so as to be able to rotate about its axis, but not to slide along the latter; it has a screw thread 9 onto which the zipper 7 is screwed;

   its front end 10 passes through the dial in an opening 11 and has a slot 12. 13 is the usual jumper determining the winding and time-setting positions of the zipper and 14 is a spring tending to hold the stud 6 in the throat 5.



  Fig. 2 shows the pull tab engaged with the winding stem; to release it, it suffices, using the slot 12, to rotate, in the desired direction, the shaft 8. The pull-tab then moves along the shaft away from the rod; if the shaft 8 is turned in the opposite direction, it approaches it.
