Description
Pièce d'horlogerie à remontage automatique par masse oscillante. La présente invention a pour objet une pièce < l'horlogerie à. remontage automatique par masse oscillante; cette pièce d'horlogerie est, caractérisée par le fait que la masse de reiuontage est. supportée par un bras élas tique non rectiligne et conformé de faon ù, amortir les chocs radiaux que subit la masse.
Le dessin annexé représente, à. titre d'exemple, une forme d'exécution de l'objet de l'invention et deux variantes.
La fig. 1 est -une vue en plan d'une pièce d'horlogerie, et les fig. 2 et 3 sont des vues en plan -de dé tails des deux variantes.
La pièce d'horlogerie représentée com prend une masse oscillante de remontage 1. supportée par un bras élastique mince 2, des tiné à amortir les chocs axiaux que petit subir la masse; ce bras 2 est solidaire d'un pignon 3 engrenant avec un secteur denté 4. Ce der nier porte un cliquet 5 coopérant avec le rochet 6 du barillet. Deux ressorts amortis seurs 7 limitent les oscillations de la masse. Le bras élastique 2 n'est pas rectiligne, mais s'étend en zigzag de façon à amortir les chocs radiaux que subit la masse. Ce bras est venu d'une pièce avec la masse ou avec le support de masse.
Dans la variante de la fig. 2, le bras élas tique désigné par 8 a la. forme d'un U, tandis que dans la forme d'exécution de la fig. 33, le bras élastique 9 est curviligne.
Self-winding timepiece by oscillating weight. The present invention relates to a part <watchmaking. automatic winding by oscillating weight; this timepiece is characterized by the fact that the reiuontage mass is. supported by a non-rectilinear elastic arm and shaped so as to absorb the radial shocks to which the mass is subjected.
The accompanying drawing represents, to. by way of example, one embodiment of the object of the invention and two variants.
Fig. 1 is a plan view of a timepiece, and FIGS. 2 and 3 are detailed plan views of the two variants.
The timepiece shown com takes a winding oscillating mass 1. supported by a thin elastic arm 2, designed to absorb the axial shocks that the mass undergoes; this arm 2 is integral with a pinion 3 meshing with a toothed sector 4. This latter carries a pawl 5 cooperating with the ratchet 6 of the barrel. Two damped springs 7 limit the oscillations of the mass. The elastic arm 2 is not rectilinear, but extends in a zigzag fashion so as to damp the radial shocks to which the mass is subjected. This arm came in one piece with the mass or with the mass support.
In the variant of FIG. 2, the elastic arm designated by 8 a la. U-shaped, while in the embodiment of FIG. 33, the elastic arm 9 is curvilinear.
