Description

  

      Mécanisme    de remontoir et de mise à l'heure.    Dans la plupart des montres la tige de  remontoir est maintenue en place au moyen  d'une tirette, laquelle vient appuyer dans une  gorge pratiquée dans la tige de remontoir.  La tirette est vissée en place au moyen -d'une  vis qui pivote dans la platine et dans le  pont du barillet. Ce dispositif présente l'in  convénient que la fixation de la tige n'offre  pas la sécurité voulue en ce sens que, de  par le mouvement angulaire de la tirette,  celle ci peut à la longue se dévisser. En  se dévissant, la pénétration de la tirette dans  la gorge de la tige de remontoir est diminuée  et il en résultera qu'au bout d'un certain  temps la tige s'arrachera lors de la mise à  l'heure tout particulièrement.

   Tous les hor  logers connaissent ce cas et l'exemple des  tiges- perdues est très fréquent. D'autre part,  l'opération du vissage est longue et délicate  et demande des soins tout spéciaux de la  part de l'ouvrier.  



  La présente invention a précisément pour  but de remédier aux     différents    défauts signalés.    Son objet est un mécanisme de remontoir et  de mise à l'heure qui est caractérisé en ce  qu'à la place de la vis de tirette employée  habituellement, la tirette est montée en place  au moyen d'un axe sur lequel elle est engagée  et qui librement tourillonné dans des parties  de support du mouvement, est maintenu en  place dans celles-ci au moyen d'un verrou  ajusté à frottement gras dans l'une desdites  parties de support et dont le dégagement  permet le dégagement . de la tirette d'avec  la tige de remontoir.  



  Le dessin annexé représente, à titre  d'exemple, une forme d'exécution de l'objet  de l'invention. La     fig.    1 en est une coupe  et la fig. 2 un plan.  



  La tirette A est chassée ou fixée sur  l'axe B. Elle :s'engage dans la gorge habi  tuelle de la tige de remontoir C.  



       L'axe    B de la tirette pivote librement,  d'une part, dans la potence D et, d'autre  part, dans le pont     .E.    Il est normalement  maintenu en place dans ces parties de sup-      port D,     E    au moyen d'un verrou     .F    ajusté  à frottement gras dans le pont     E.     



  Pour sortir la tige de remontoir, il suffit  de     tourner    le verrou     E    jusqu'au moment où  une partie fraisée ou découpée du verrou se  trouve placée tangentiellement à l'axe de  tirette B. A ce moment, un ressort à bou  din G monté sur l'axe B entre un épaule  ment<I>b</I> de celui-ci et la potence<I>D</I> exerce  une pression sur l'axe B de la tirette. La  tirette A qui y est chassée sur l'axe B se  trouve ainsi dégagée automatiquement de la  rainure pratiquée dans la tige de remontoir  et cette dernière peut ainsi être retirée faci  lement du mouvement. Pour se rendre compte  si la tirette     9.    repose bien dans la gorge de  la tige de remontoir, il a été prévu un gui  chet H dans le pont     E.     



  Pour remettre la tige de remontoir en  place, on procède en sens inverse,     c'est-à-          dire    on commence par introduire la tige de  remontoir dans les parties correspondantes  de la potence D, puis on exerce une pres  sion sur la tête de l'axe B de la tirette  jusqu'à ce que le bec de tirette se trouve  logé dans la gorge de la tige de remontoir  et on tourne finalement lé verrou     F    jusqu'à    ce que la partie pleine dudit verrou recouvre  la tête de l'axe de tirette.



      Winding and time-setting mechanism. In most watches, the winding stem is held in place by means of a pull tab, which presses into a groove made in the winding stem. The zipper is screwed in place by means of a screw which pivots in the plate and in the barrel bridge. This device has the disadvantage that the fixing of the rod does not offer the desired security in the sense that, by the angular movement of the zipper, the latter can unscrew over time. By unscrewing, the penetration of the zipper in the groove of the winding stem is reduced and the result will be that after a certain time the stem will tear off when setting the time in particular.

   All hor logers know this case and the example of lost stems is very frequent. On the other hand, the screwing operation is long and delicate and requires very special care on the part of the worker.



  The object of the present invention is precisely to remedy the various faults reported. Its object is a winding and time-setting mechanism which is characterized in that instead of the zipper screw usually employed, the zipper is mounted in place by means of an axis on which it is engaged and which freely journalled in movement support parts, is held in place therein by means of a latch fitted with greasy friction in one of said support parts and the disengagement of which allows disengagement. of the pull tab with the winding stem.



  The appended drawing represents, by way of example, an embodiment of the object of the invention. Fig. 1 is a section and FIG. 2 a plan.



  The zipper A is driven out or fixed on the axis B. It: engages in the usual groove of the winding stem C.



       The axis B of the zipper pivots freely, on the one hand, in the stem D and, on the other hand, in the bridge .E. It is normally held in place in these support parts D, E by means of a .F latch fitted with greasy friction in the bridge E.



  To remove the winding stem, all you have to do is turn the latch E until a milled or cut part of the latch is placed tangentially to the pull pin B. At this time, a coil spring G mounted on the axis B between a shoulder <I> b </I> of this one and the stem <I> D </I> exerts a pressure on the axis B of the zipper. The pull tab A which is driven there on the axis B is thus automatically released from the groove made in the winding stem and the latter can thus be easily removed from the movement. To see if the zipper 9. rests well in the groove of the winding stem, a gui chet H has been provided in the bridge E.



  To put the winding stem back in place, we proceed in reverse order, that is to say we start by inserting the winding stem into the corresponding parts of the stem D, then pressure is exerted on the head of the stem. 'axis B of the zipper until the zipper spout is housed in the groove of the winding stem and the lock F is finally turned until the solid part of said lock covers the head of the axis pull tab.
