Description

  

  Pièce d'horlogerie à remontage automatique par masse oscillante.    La présente invention a pour objet     une     pièce d'horlogerie à remontage automatique  par masse oscillante. Cette pièce est caracté  risée en ce que cette masse oscille autour du  centre du mouvement et tourne autour d'un  axe pivotant dans le     bâti    de ce mouvement  et dans le fond de la pièce.  



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



  La     fig.    1 en est une vue en plan et la       fig.    2 une coupe axiale par     II-II    de la       fig.    1; la     fig.    3 est une coupe     schématique     à plus grande échelle du mécanisme de re  montage.  



  La forme d'exécution représentée com  prend une boîte 1 avec un fond 2 et un mou  vement 3.  



  Le bâti du mouvement 3     porte    en son  centre une pierre 4 dans laquelle pivote l'axe  6 de la masse oscillante 5; l'autre     extrémité     de l'axe 6 pivote dans une pierre 7 fixée au  centre du fond 2. La masse oscillante 5    affecte la forme d'un disque d'un diamètre  sensiblement égal à celui du mouvement et  échancré; elle est folle sur l'axe 6.     Sur    cet  axe 6 sont figées deux roues dentées, l'une 8  au-dessous, l'autre 9 au-dessus de la masse  oscillante. La roue 8 engrène avec une roue  10 qui transmet le mouvement par friction à  une roue 11 qui coopère avec une roue 12  dont le pignon<B>13</B> entraîne une roue 14 dont  le pignon 15 agit sur le rochet 16 du     ba-          rillet-moteur.     



  Avec la roue dentée 9 coopère un     cliquet     17 porté par la masse et sollicité par un  ressort 18     figé    en 19 à la masse, le tout de  manière que, le cliquet 17 engrenant avec la  roue 9, la masse oscillante soit solidaire de  son axe 6 lorsqu'elle se meut dans le     sens     correspondant au remontage du ressort; dans       l'autre    sens, le cliquet 17 glisse sur la roue 9  et libère la masse 5.  



  La forme de disque échancré donnée à la  masse oscillante permet de réaliser une masse  assez lourde dont le centre de gravité est re  porté hors du centre de     rotation.         La disposition     susdécrite    présente<B>plu-</B>  sieurs avantages: tout d'abord, la position de  la masse en dehors du mouvement permet de  donner à celle-ci un volume assez grand sans       augmenter    sensiblement le diamètre de la  montre;     ensuite,    le     pivotage    de lamasse dans  le bâti du mouvement et dans le fond écono  mise un pont supplémentaire, simplifie la  construction et diminue l'épaisseur de la  montre.



  Self-winding timepiece by oscillating weight. The present invention relates to a timepiece with automatic winding by means of an oscillating mass. This part is characterized in that this mass oscillates around the center of the movement and rotates around a pivoting axis in the frame of this movement and in the back of the part.



  The appended drawing represents, by way of example, an embodiment of the object of the invention, constituted by a wristwatch of round shape.



  Fig. 1 is a plan view thereof and FIG. 2 an axial section through II-II of FIG. 1; fig. 3 is a schematic section on a larger scale of the re-assembly mechanism.



  The embodiment shown com takes a box 1 with a bottom 2 and a movement 3.



  The frame of the movement 3 carries in its center a stone 4 in which the axis 6 of the oscillating weight 5 pivots; the other end of the axis 6 pivots in a stone 7 fixed to the center of the base 2. The oscillating mass 5 takes the form of a disc with a diameter substantially equal to that of the movement and notched; it is crazy on axis 6. On this axis 6 are fixed two toothed wheels, one 8 below, the other 9 above the oscillating mass. The wheel 8 meshes with a wheel 10 which transmits the movement by friction to a wheel 11 which cooperates with a wheel 12 whose pinion <B> 13 </B> drives a wheel 14 whose pinion 15 acts on the ratchet 16 of the ba - motor rillet.



  With the toothed wheel 9 cooperates a pawl 17 carried by the mass and biased by a spring 18 fixed at 19 to the mass, all so that, the pawl 17 meshing with the wheel 9, the oscillating mass is integral with its axis 6 when it moves in the direction corresponding to the winding of the spring; in the other direction, the pawl 17 slides on the wheel 9 and releases the mass 5.



  The scalloped disc shape given to the oscillating mass makes it possible to produce a fairly heavy mass, the center of gravity of which is brought out of the center of rotation. The above-described arrangement has <B> several </B> advantages: first of all, the position of the mass outside the movement makes it possible to give it a fairly large volume without appreciably increasing the diameter of the watch; then, the pivoting of the mass in the frame of the movement and in the economy caseback provides an additional bridge, simplifies construction and reduces the thickness of the watch.

REVENDICATION Pièce d'horlogerie à remontage automa tique par masse oscillante, caractérisée en ce que cette masse oscille autour du centre du mouvement et tourne autour d'un axe pivo tant dans le bâti de ce mouvement et dans le fond de la pièce. SOUS-REVENDICATIONS 1 Pièce d'horlogerie selon la revendication, caractérisée en ce que la masse oscillante est montée folle sur son axe duquel elle peut être rendue solidaire, lorsqu'elle oscille dans le sens déterminant le remon tage du ressort, par une roue dentée fixée sur l'axe avec laquelle coopère un rochet fixé sur la masse. CLAIM Self-winding timepiece using an oscillating mass, characterized in that this mass oscillates around the center of the movement and rotates around a pivot axis both in the frame of this movement and in the back of the part. SUB-CLAIMS 1 Timepiece according to claim, characterized in that the oscillating weight is mounted loose on its axis which it can be made integral, when it oscillates in the direction determining the winding of the spring, by a toothed wheel fixed on the axis with which cooperates a ratchet fixed on the mass. 2 Pièce d'horlogerie selon la revendication. caractérisée en ce que la masse oscillante est formée d'un disque d'un diamètre sen siblement égal à celui du mouvement et échancré de manière à reporter son centre de gravité hors du centre de pivotement. 2 Timepiece according to claim. characterized in that the oscillating mass is formed of a disc with a diameter approximately equal to that of the movement and notched so as to shift its center of gravity out of the pivot center.
