Description

  

  Mécanisme de remontoir et de mise à l'heure à tirette.    Pour sortir d'une montre munie d'un mé  canisme- de remontoir et de mise à l'heure  à tirette la tige de ce mécanisme, il faut dé  gager l'ergot de la     tirette    de la rainure de  la tige de remontoir dans laquelle elle est  introduite. Pour ce faire, on a<B>déjà</B>     monté     cette tirette folle sur un axe qui peut glisser  dans son     ajustement    et qui porte un collet  au moyen duquel on peut, par une poussée  axiale sur ledit axe, faire opérer à la tirette  un mouvement :de     translation    à l'encontre  d'un ressort de maintien qui appuie l'ergot  de la, tirette dans la rainure précitée.  



       Jusqu'à    présent, ce ressort de maintien  formait un tout pour     lui-:même,    vissé quel  que part sur la platine. Cette manière de  faire exige des moyens -de fixation spéciaux  pour lesquels il est souvent difficile de trou  ver de la place.  



  L'objet de la     présente    invention est un       mécanisme    de remontoir et de mise à l'heure  à tirette dans lequel on a évité ces fixations       .spéciales    en prévoyant un sautoir de tirette  et un ressort de maintien de la     tirette    venus  de fabrication avec le pont de renvoi de mise  à l'heure qu'ils prolongent latéralement.  



  Le dessin annexé montre., à titre d'exem  ple. une forme d'exécution de l'objet de l'in  vention.  



  La fi;-. 1 est une vue en plan,  la     fi:g    2 une vue en coupe par l'axe de la  tirette.  



  En se référant à. ce dessin, la tige de re  montoir est     désignée    par 10. Elle possède    une     gorge    11 dans laquelle l'ergot 12 -de la       tirette    13 est engagé.     Cette    tirette est mon  tée folle à l'extrémité d'un arbre 14 contre  le collet 15 duquel elle est appuyée par un  ressort     @de    maintien 16. Celui-ci est venu  d'une pièce avec le pont :de renvoi de mise à,  l'heure 17 et le prolonge latéralement.  



  Le sautoir -de tirette 18 qui agit .sur     cette     dernière par pression latérale est également  sorti de la même pièce qui porte encore un       troisième    prolongement     latéral        23.    pour te  nir en place, sur son pivot     23a,    la bascule 24  qui     transmet    au pignon coulant 25 les mou  vements     @de    la     tirette.    Le tout est maintenu  en place par des vis 19 et 20, cette dernière  formant l'axe 26     idu    renvoi de mise à  l'heure 21.  



       Lorsqu'au    moyen d'un     outil,    on appuie  sur le bout évidé 22 de l'axe 14, on peut  faire glisser ce dernier et faire subir à la  tirette 13 un mouvement     @de    translation à  l'encontre de     l'effet    du ressort de maintien  16 pour dégager l'ergot 12 :de la rainure 11.  Ceci fait, la tige de remontoir peut être re  tirée du mouvement.  



  Cette construction a l'avantage     d'éviter     toutes les fixations qui jusqu'ici étaient né  cessaires pour fixer le     ressort    de maintien  au bâti.  



  Le bout de     :ce    ressort peut naturellement  appuyer aussi bien d'un côté que de l'autre  de l'axe 14, c'est-à-dire à une plus ou moins  grande distance de l'ergot 4e     tirette    12.



  Pull-down winding and time-setting mechanism. To exit a watch fitted with a pull-down winding and time-setting mechanism, the stem of this mechanism must be disengaged from the lug of the pull-tab from the groove of the winding stem in which it is introduced. To do this, we have <B> already </B> mounted this idler zipper on an axis which can slide in its adjustment and which carries a collar by means of which it is possible, by an axial thrust on said axis, to operate at the zipper movement: translational against a retaining spring which supports the lug of the zipper in the aforementioned groove.



       Until now, this retaining spring formed a whole for itself, screwed somewhere on the plate. This way of proceeding requires special fixing means for which it is often difficult to find space.



  The object of the present invention is a zipper winding and time-setting mechanism in which these special fixings have been avoided by providing a zipper jumper and a zipper retaining spring from manufacture with the bridge. of the time setting that they extend laterally.



  The accompanying drawing shows., By way of example. an embodiment of the object of the invention.



  The fi; -. 1 is a plan view, fi: g 2 a sectional view through the axis of the pull tab.



  To refer at. in this drawing, the re-mount rod is designated by 10. It has a groove 11 in which the lug 12 of the pull-tab 13 is engaged. This zipper is my crazy tee at the end of a shaft 14 against the collar 15 of which it is supported by a retaining spring 16. This one came in one piece with the bridge: for setting return, hour 17 and extends it laterally.



  The jumper -de zipper 18 which acts on the latter by lateral pressure is also out of the same part which still carries a third lateral extension 23. to stay in place, on its pivot 23a, the rocker 24 which transmits to the sliding pinion 25 the movements @of the zipper. The whole is held in place by screws 19 and 20, the latter forming the axis 26 idu the time setting reference 21.



       When, by means of a tool, the recessed end 22 of the pin 14 is pressed, the latter can be slid and the pull-tab 13 subjected to a translational movement against the effect of the spring retaining 16 to release the lug 12: from the groove 11. This done, the winding stem can be withdrawn from the movement.



  This construction has the advantage of avoiding all the fasteners which hitherto were necessary to fix the retaining spring to the frame.



  The end of: this spring can naturally press as well on one side as on the other of the axis 14, that is to say at a greater or lesser distance from the 4th tab 12.
