Description

  

  Pièce     d'horlogerie    dont le remontage s'effectue automatiquement.    L'objet de la présente invention est une  pièce d'horlogerie dont le remontage s'effectue  automatiquement par le moyen d'une masse  oscillante qui, pour chaque sens d'oscillation,  met en prise avec une roue dentée transmet  tant au mécanisme moteur alternativement  l'un ou l'autre de deux cliquets appuyés  contre les dents de cette roue par ressort.

    Cette pièce d'horlogerie est caractérisée en  ce que les deux cliquets sont montés sur  deux pivots portés par la masse oscillante  de part et d'autre du pivot de cette masse  et de part et d'autre de la droite qui relie  ce pivot à l'axe de la roue dentée à entraî  ner, de façon que, quand la masse oscillante  se déplace dans un sens, un des pivots de  cliquet se rapproche et l'autre s'écarte dudit  axe et inversement quand la masse oscillante  se déplace dans l'autre sens.  



  Le dessin annexé représente schématique  ment l'objet de l'invention.  



  1 désigne le boîtier renfermant le méca  nisme d'horlogerie et 2 la masse qui, par ses  oscillations autour de son pivot 3, doit re-    monter le ressort moteur. Ce ressort moteur  est enfermé, de la manière habituelle, dans  le barillet 4 dont l'axe est précisément le  pivot 3. La masse 2 et le barillet 4 sont  libres sur l'axe 3.  



  Sur cet axe est calé une roue dentée 6  en prise avec un pignon 7 monté sur l'axe  16 et solidaire d'une roue à rochet 8.  



  Normalement, la masse 2 tend à prendre  la position de repos représentée en traits  pleins; elle ne quitte cette position que sous  l'effet d'un déplacement ou d'un choc reçu  par le boîtier 1 et, dans ce cas, elle oscille,  à la façon d'un balancier, dans la creusure 5  pratiquée dans le boîtier 1 et qui limite  l'amplitude des oscillations (à environ<B>900</B>  dans l'exemple). Pendant ces oscillations, la  masse 2 détermine la rotation du rochet 8  dans le sens du remontage et ce, quel que  soit le sens d'oscillation de la masse 2.

   A  cet effet cette masse porte, de part et d'autre  du pivot 3 et de part et d'autre de la droite  reliant les axes 3 et 16, les pivots 11 et 12  de deux     cliquets    9 et 10, parallèles, et qu'un      ressort à deux branches 14, 15, appuyé     cri     13, tend à appliquer contre les dents du ro  chet 8.     Jusqu'à    la position en pointillés de  la masse 2, c'est-à-dire     presqu'à    fin de course  à gauche, le cliquet 10 continue à pousser  sur les dents de 8, tandis que le cliquet 9  glisse sur ces dents. Dans le mouvement de  retour de la masse 2, le cliquet 9, dont le  pivot se rapproche de l'axe 16,     entraine    la  roue 8, tandis que le cliquet 10 glisse sur les  dents de 8, son pivot s'écartant de l'axe 16.  



  Le mécanisme de transmission entre la       masse    2 et la roue 6 calée sur le pivot de  remontage 3 est donc extrêmement simple  et peu encombrant; il peut s'adapter aux  montres les plus petites sans     entrafner    de  modification de forme ni d'épaisseur et sans  nécessiter le déplacement d'autres pièces. On  conçoit que, pour une montre de forme ronde  par exemple, la masse 2 pourrait être pivo  tée sur un autre axe     que    3, par exemple au  centre de la montre.



  Timepiece whose winding takes place automatically. The object of the present invention is a timepiece, the winding of which is carried out automatically by means of an oscillating weight which, for each direction of oscillation, engages with a toothed wheel transmits both to the motor mechanism alternately one or the other of two pawls pressed against the teeth of this wheel by spring.

    This timepiece is characterized in that the two pawls are mounted on two pivots carried by the oscillating mass on either side of the pivot of this mass and on either side of the line which connects this pivot to the axis of the toothed wheel to be driven, so that when the oscillating mass moves in one direction, one of the pawl pivots approaches and the other moves away from said axis and vice versa when the oscillating mass moves in the 'other way.



  The accompanying drawing schematically represents the subject of the invention.



  1 designates the case containing the clockwork mechanism and 2 the mass which, by its oscillations around its pivot 3, must raise the mainspring. This mainspring is enclosed, in the usual way, in the barrel 4, the axis of which is precisely the pivot 3. The mass 2 and the barrel 4 are free on the axis 3.



  On this axis is wedged a toothed wheel 6 in engagement with a pinion 7 mounted on the axis 16 and integral with a ratchet wheel 8.



  Normally, the mass 2 tends to take the rest position shown in solid lines; it leaves this position only under the effect of a displacement or a shock received by the housing 1 and, in this case, it oscillates, like a pendulum, in the recess 5 made in the housing 1 and which limits the amplitude of the oscillations (to approximately <B> 900 </B> in the example). During these oscillations, mass 2 determines the rotation of ratchet 8 in the winding direction, regardless of the direction of oscillation of mass 2.

   For this purpose this mass carries, on either side of the pivot 3 and on either side of the straight line connecting the axes 3 and 16, the pivots 11 and 12 of two pawls 9 and 10, parallel, and that a spring with two branches 14, 15, pressed cry 13, tends to apply against the teeth of the rock 8. Up to the dotted position of the mass 2, that is to say almost to the end of travel at left, the pawl 10 continues to push on the teeth of 8, while the pawl 9 slides on these teeth. In the return movement of the mass 2, the pawl 9, the pivot of which approaches the axis 16, drives the wheel 8, while the pawl 10 slides on the teeth of 8, its pivot moving away from the axis 16.



  The transmission mechanism between the mass 2 and the wheel 6 wedged on the winding pivot 3 is therefore extremely simple and compact; it can be adapted to the smallest watches without causing any change in shape or thickness and without requiring the displacement of other parts. It will be understood that, for a watch of round shape for example, the mass 2 could be pivoted on an axis other than 3, for example at the center of the watch.
