Description

  

  <B>Mécanisme de remontoir et mise à l'heure à tirette.</B>    Les mouvements destinés à des boîtes dont  la carrure et le fond sont d'une seule pièce  ou assemblés à demeure ont des tiges de re  montoir en deux pièces dont les inconvé  nients sont connus des hommes du métier. Les  tiges en une pièce étaient jusqu'ici inadmis  sibles pour ce genre de montres, car la vis de  tirette qui, tout en servant de pivot pour  cette dernière, maintient indirectement la tige  de remontoir dans le mouvement, n'est acces  sible que du côté du mouvement. tourné vers  le fond de la boîte.  



  Le but de l'invention est de permettre  l'usage de tiges en une seule pièce dans les  boîtes du genre précité. Pour cela, on a prévu  un pivot de tirette susceptible d'un mouve  ment axial permettant d'accoupler et de dés  accoupler le bec de la tirette de la tige de  remontoir sans dévissage.  



  De préférence, le bec de tirette sera co  nique et coopérera avec une gorge de forme  correspondante pratiquée dans la tige de re  montoir.  



  Le dessin représente, partiellement et. à  titre d'exemples, trois formes d'exécution de  l'objet de l'invention.  



  La     fig.    1 est. une vue en élévation de la  tige de remontoir avec la tirette.  



  La     fig.    2 en est une coupe selon la ligne  I1-11 de la     fig.    1.  



  La     fig.    3 est une coupe analogue à celle  de la     fig.    2, d'une seconde forme d'exécution.  La     fig.    4 est également une coupe ana  logue, mais d'un troisième exemple.    En se référant aux     fig.    1. et 2, 1 désigne  la tige de remontoir, 10 la platine du mouve  ment, 3 la tirette et 4 la vis de tirette.  



  Le bec de tirette 5 est conique; il pénètre  dans une rainure circulaire ou gorge 6, de  forme correspondante de la tige de re  montoir.  



  La vis de tirette 4, qui sert de pivot, com  porte un collet 7 sous lequel est, placé un  ressort 8, bandé pour appuyer ledit collet.  contre le fond d'une     noyure    9 prévue     mi-          partie    dans la platine 10, mi-partie dans le  pont 2 se trouvant en cet endroit.  



  Le canon 11 de la vis de tirette est guidé  dans un passage de la platine.  



  Dans cette construction, la vis de tirette,  donc son pivot, est susceptible d'un mouve  ment axial, ce qui se produit chaque fois que       lorsqu'en    tirant fortement sur la. tige 1, on  fait monter le bec de la tirette sur le côté  de la rainure circulaire 6; la tige est alors  libérée. La mise en place de cette dernière  s'opère en l'introduisant dans le passage du  mouvement qui lui est réservé. Après avoir  glissé sur la tige, le bec 5 tombe dans la rai  nure et maintient la tige en place. La ten  sion du ressort 8 est suffisante pour que les  mouvements de la tige, lors de la mise à  l'heure, soient communiqués à la tirette et de  celle-ci au pignon coulant sans qu'un     désac-          couplement    de cette tige et du bec de tirette  ait. lieu.  



  Dans la forme d'exécution selon la     fig.    3,  la vis de tirette 4 ne traverse pas le pont 2.      Elle possède     une    tête 12 sous laquelle prend  le ressort 8 qui s'appuie, d'autre part, contre  la platine 10. Le     fonctionnement    d'un méca  nisme équipé de cette vis-pivot est le même  que celui de l'exemple précédent.  



  Dans la forme d'exécution selon la     fig.    4,  la vis de tirette est supprimée; le pivot de  tirette 13 est chassé dans celle-ci qui est  maintenue en place par un ressort-lame 14  permettant un mouvement axial du pivot  pour le     désaccouplement    de la tirette et de  la tige.



  <B> Winding mechanism and pull-down time setting. </B> The movements intended for cases whose middle and back are in one piece or permanently assembled have two-piece winding stems whose drawbacks are known to those skilled in the art. One-piece stems have hitherto been inadmissible for this type of watch, because the pull-tab screw which, while serving as a pivot for the latter, indirectly maintains the winding stem in the movement, is only accessible from the side of the movement. facing the bottom of the box.



  The object of the invention is to allow the use of rods in one piece in boxes of the aforementioned type. For this, a zipper pivot capable of axial movement has been provided, making it possible to couple and uncouple the spout of the zipper of the winding stem without unscrewing.



  Preferably, the zipper spout will be conical and will cooperate with a correspondingly shaped groove made in the re-mount rod.



  The drawing represents, partially and. by way of examples, three embodiments of the object of the invention.



  Fig. 1 is. an elevation view of the winding stem with the pull tab.



  Fig. 2 is a section along the line I1-11 of FIG. 1.



  Fig. 3 is a section similar to that of FIG. 2, of a second embodiment. Fig. 4 is also an analogous section, but of a third example. Referring to Figs. 1. and 2, 1 designates the winding stem, 10 the movement plate, 3 the pull tab and 4 the pull screw.



  The pull tab 5 is conical; it enters a circular groove or groove 6 of the corresponding shape of the re-mount rod.



  The zipper screw 4, which serves as a pivot, com carries a collar 7 under which is placed a spring 8, tensioned to support said collar. against the bottom of a groove 9 provided half-part in the plate 10, half-part in the bridge 2 located at this location.



  The barrel 11 of the zipper screw is guided in a passage of the plate.



  In this construction, the pull-tab screw, therefore its pivot, is capable of axial movement, which occurs each time when pulling strongly on the. rod 1, the spout of the pull tab is mounted on the side of the circular groove 6; the rod is then released. The installation of the latter takes place by introducing it into the passage of the movement reserved for it. After having slipped on the rod, the spout 5 falls into the groove and holds the rod in place. The tension of the spring 8 is sufficient so that the movements of the rod, when setting the time, are communicated to the pull-tab and from the latter to the sliding pinion without disconnecting this rod and the zipper spout. location.



  In the embodiment according to FIG. 3, the pull-tab screw 4 does not cross the bridge 2. It has a head 12 under which the spring 8 takes which is supported, on the other hand, against the plate 10. The operation of a mechanism equipped with this screw-pivot is the same as that of the previous example.



  In the embodiment according to FIG. 4, the zipper screw is removed; the pull-tab pivot 13 is driven therein which is held in place by a leaf spring 14 allowing axial movement of the pivot for the disconnection of the pull-tab and the rod.
