Description

  

      Dispositif    de remontage automatique de pièce d'horlogerie.    La     présente    invention a pour objet un       dispositif    de remontage automatique de pièce  d'horlogerie,     @comprenant    une     masse,    de re  montage oscillante reliée au     ressort-moteur     par     l'intermédiaire    d'un     dispositif    -de     trans-          mission    de mouvement.

       Ce    dispositif     est        ca-          ractérisé    en ce qu'il comprend un     levier     monté de façon oscillante     sur    le     bâti    et dont  un     bras    se termine par une     denture        engrenant     avec un pignon porté par la masse taudis que  l'autre bras,     s'étendant    de     l'autre        côté    du  point d'oscillation,

       porte    un     cliquet    coopérant  avec la roue d'un mobile dont le .centre est  distinct de celui du levier et dont le pignon  commande le     ressort-moteur.     



  Le dessin ci-annexé montre, à     titre     d'exemple, une forme     d'exécution    de l'objet  de l'invention.  



  La     fig.    1 en est     une    vue en plan, et  la     fig.    2     une    coupe suivant la ligne       A-B-C-D    de f     ig.    1.  



       .A    la     masse    de remontage 1 est fixée par  des vis, une     plaquette    2 solidaire d'un     pignon     3 qui est pivoté     entre        deux    ponts supplémen  taires 4 et 5     disposés        au-dessus.    du pont de  finissage.

   Le pont     supplémentaire    5     sert    aussi  de palier au pivot du levier 6 dont un bras  se     termine    par     une        denture    7 en     prise    avec  le pignon 3     susmentionné    et dont l'autre     bras     s'étendant de l'autre côté     @du    pivot     porte    un  cliquet 8     qu'un    ressort 9 tend à appliquer  contre la denture     de    la roue     du:        mobile    10.

   Ce  mobile     pivote        aussi        dans    le     pont    supplémen  taire 5, mais son     centre        est        distinct    de celui    du levier 6. Le pignon du     mobile    10 est en       prise    avec la. roue de     couronne    11, qui peut  être également actionnée par la     couronne    13,  et qui engrène avec le     rochet:    de     barillet    12.

   La  roue de couronne est     maintenue    par une ron  delle 14 et sur     cette    rondelle     est    pivoté en 15  un cliquet de     retenue    16.  



  Lorsque la masse 1     oseille    dans le sens  de la flèche F, le     pignon    3,     porté    par la  masse, fait osciller le     levier    6 portant le     cli-          quet    8. Ce cliquet fait tourner le mobile 10  qui actionne la     roue    de couronne e t le rochet  de barillet -et remonte ainsi le     ressort-moteur.     



       Lorsque    la     masse    oscille dans     l'autre        sens,     le     cliquet    8 glisse sur les dents de la     roue    du  mobile 10,     celui-ci    étant     retenu    par le     cli-          quet    16.  



  Le pignon du mobile 10     pourrait    être en       relation        directe    avec le rochet dû barillet.



      Automatic winding device for a timepiece. The present invention relates to a device for automatic winding of a timepiece, comprising a mass, for oscillating re-assembly connected to the mainspring by means of a movement transmission device.

       This device is charac- terized in that it comprises a lever mounted in an oscillating manner on the frame and one arm of which ends in a toothing meshing with a pinion carried by the slum mass that the other arm, extending from the 'other side of the oscillation point,

       carries a pawl cooperating with the wheel of a mobile whose center is distinct from that of the lever and whose pinion controls the mainspring.



  The accompanying drawing shows, by way of example, one embodiment of the object of the invention.



  Fig. 1 is a plan view thereof, and FIG. 2 a section along line A-B-C-D of f ig. 1.



       .A the winding mass 1 is fixed by screws, a plate 2 integral with a pinion 3 which is pivoted between two additional bridges 4 and 5 arranged above. of the finishing deck.

   The additional bridge 5 also serves as a bearing for the pivot of the lever 6, one arm of which ends in a toothing 7 in engagement with the aforementioned pinion 3 and the other arm of which extending on the other side of the pivot carries a pawl 8. that a spring 9 tends to apply against the toothing of the wheel of: mobile 10.

   This mobile also pivots in the additional bridge 5, but its center is distinct from that of the lever 6. The pinion of the mobile 10 is engaged with the. crown wheel 11, which can also be actuated by crown 13, and which meshes with ratchet: barrel 12.

   The crown wheel is held by a ron delle 14 and on this washer is pivoted 15 a retaining pawl 16.



  When the mass 1 sorrel in the direction of arrow F, the pinion 3, carried by the mass, oscillates the lever 6 carrying the pawl 8. This pawl turns the mobile 10 which actuates the crown wheel and the ratchet. barrel -and thus reassembles the mainspring.



       When the mass oscillates in the other direction, the pawl 8 slides on the teeth of the wheel of the mobile 10, the latter being retained by the pawl 16.



  The pinion of the mobile 10 could be in direct relation with the ratchet of the barrel.
