Description

  

  Montre dont le remontage et la mise à l'heure s'effectuent au moyen d'un organe  tournant concentriquement à l'axe géométrique des aiguilles de la montre.    L'objet de la     présente    invention est une       montredont    le remontage et la.

   mise à l'heure  s'effectuent au moyen d'un organe tournant       concentriquement    à l'axe géométrique     des.     aiguilles de la montre et comportant un se  cond organe de commande dont les     dsplaee-          ments    autour de l'axe     géométrique,des    aiguil  les de la montre impriment à une tige de  remontage et de mise à l'heure un mouvement  de     translation    rectiligne pour l'amener dans  la position     désirée.     



  La     montre    selon l'invention est     earactéri-          sée    en     ce    que le second     :desdits        organes    est  maintenu dans une rainure limitée d'un côté  par la lunette et     cde    l'autre par le fond de la       boîte    de montre et dont le fond est constitué  par un cercle     porte-mouvement.     



       Le        dessin        représente,    à     titre    d'exemple,       -deux    formes d'exécution d'une     mointre    selon  la. présente     invention.     



  Il s'agit ici d'une montre-bracelet.  



  La fi-. 1 est une coupe diamétrale de la  première.  



  La     fig.    2 est une coupe     partielle    selon la  ligne     II-II,     la     fig.    3 une coupe     @diamétrale    -de la se  conde,  la     fig.    4 une vue en plan de la     montre-          bracelet.     



  Dans la montre représentée en     fig.   <B>1,</B> le  mouvement 6 est maintenu dans un cercle  porte-mouvement 2 venu de     fabrication    avec  la lunette 1. Le fond 4     présente    une saillie    annulaire filetée 5 qui coopère     avec    un pas  de vis du porte-mouvement 2 pour bloquer  le     mouvement    à     l'intérieur    de ce deux     pièces.     



  La     lunette    1 et le fond 4 dépassent le  pourtour extérieur du     porte-mouvement    2  pour     former    une rainure périphérique de la  montre-bracelet dans     laquelle    est ajustée un,  cercle 8 en prise     avec    un pignon 10 calé sur  la     tige,de        remontoir    11. La carrure 12 et un  cercle 14 sont également logés     dans        -cette    rai  nure.

   Ce cercle porte un organe de commande  15, en forme :de cornière, fixé audit cercle 14  par .des vis 21 et     dont    l'aile     perpendiculaire     au     cadran,    de la montre forme une rampe ou  came et pénètre dans un     espace    compris entre  le pignon de     remontage    10 et un collet 16  fixé sur     cette    tige de remontage.

       Cette    aile  20 de l'organe 15 de commande est arquée  et sa     distance    au     centre    de rotation varie de  l'un de     ses    bouts à     l'autre,    si bien que lors  qu'on     tourne    le cercle 14 d'un certain angle,  la tige de remontage opère un     mouvement    de       translation    rectiligne selon son axe et     est    ame  née soit -dans la position de remontage, soit  chus la position de mise à l'heure selon  qu'elle se trouve à l'une     ou    à l'autre des ex  trémités de la     partie    20 de l'organe.  



       Le        eercle    8 peut être ajusté très exacte  ment avec la carrure dans la rainure     ména-          nagée    entre les bords de la lunette     et,du    fond.  On aura donc     toujours    un dispositif bien     mé-          ea.nique    dont l'usure est négligeable et dont  la robustesse est plus que     suffisante    pour      supporter les fatigues     auxquelles    le dispositif  peut être     soumis    dans le cas d'une     montre-          bracelet.     



  Dans la forme     :d'exécution    selon la     -fig.    3,       forgane    de     commande    15 est     fixé    à la carrure  12, son     aile    20     prend    également sus le pignon  10     deela        tige    de remontoir et sa -course est       limitée    par     -des        chevilles    19     plantées        dans.    le  cercle porte-mouvement 2.

   Ici également,     les     différentes,     pièces        contenues        dans    la rainure  peuvent être     dimensionnées    de manière à for  mer un tout     mécaniquement        impeccable.  



  Watch whose winding and time setting are carried out by means of a rotating organ concentrically to the geometric axis of the watch hands. The object of the present invention is a watch whose winding and.

   time setting are performed by means of a rotating member concentrically to the geometric axis of. hands of the watch and comprising a second control member whose displacements around the geometric axis, the hands of the watch impart to a winding and time-setting rod a rectilinear translational movement for the watch. 'bring to the desired position.



  The watch according to the invention is activated in that the second: of said members is held in a groove limited on one side by the bezel and on the other by the back of the watch case and of which the back is formed by a movement-carrying circle.



       The drawing represents, by way of example, two embodiments of a mointre according to the. present invention.



  This is a wristwatch.



  The fi-. 1 is a diametrical section of the first.



  Fig. 2 is a partial section along line II-II, FIG. 3 a diametral section of the second, FIG. 4 a plan view of the wristwatch.



  In the watch shown in FIG. <B> 1, </B> the movement 6 is held in a movement-carrying circle 2 produced with the bezel 1. The back 4 has a threaded annular projection 5 which cooperates with a thread of the movement-holder 2 to block movement inside this two-piece.



  The bezel 1 and the base 4 protrude beyond the outer periphery of the movement holder 2 to form a peripheral groove of the wristwatch in which is fitted a circle 8 engaged with a pinion 10 wedged on the stem, winding 11. middle part 12 and a circle 14 are also housed in this groove.

   This circle carries a control member 15, in the form of an angle iron, fixed to said circle 14 by screws 21 and whose wing perpendicular to the dial, of the watch forms a ramp or cam and enters a space between the pinion winding 10 and a collar 16 fixed to this winding rod.

       This wing 20 of the control member 15 is arcuate and its distance from the center of rotation varies from one of its ends to the other, so that when the circle 14 is rotated by a certain angle, the winding rod operates a rectilinear translational movement along its axis and is born either -in the winding position, or from the time-setting position depending on whether it is at one or the other of the ex tremités of part 20 of the organ.



       The circle 8 can be adjusted very exactly with the caseband in the groove made between the edges of the bezel and the back. We will therefore always have a very mechanical device whose wear is negligible and whose robustness is more than sufficient to withstand the fatigue to which the device may be subjected in the case of a wristwatch.



  In the form: of execution according to -fig. 3, forgane control 15 is fixed to the middle part 12, its wing 20 also takes on the pinion 10 deela winding rod and its -course is limited by -pegs 19 planted in. the movement carrier circle 2.

   Here too, the different parts contained in the groove can be dimensioned so as to form a mechanically flawless whole.
