Abstract

Organe moteur (1) pour mouvement d'horlogerie comportant: un barillet (2) monté sur un arbre (3) de sorte à pouvoir tourner autour d'un axe (4) de l'arbre (3) lorsque l'organe moteur (1) est remonté; une unité ressort moteur comprenant un premier et deuxième ressorts (8, 11) enroulés à l'intérieur du barillet (2) de façon superposée et coaxiale l'un par rapport à l'autre, le premier et le deuxième ressort (8, 11) étant couplé à l'une de leur extrémité au barillet (2) et à l'arbre (3), respectivement; l'unité comprenant en outre un plateau (14) monté coaxial entre les deux ressorts (8, 11); caractérisé en ce que le plateau (14) est monté en rotation sur l'axe (4); et en ce que le premier et le deuxième ressort (8, 11) est couplé à leur autre extrémité au centre (16) et à la périphérie (15) du plateau (14), respectivement, de sorte que les deux ressorts (8, 11) s'arment simultanément autour de l'axe (4) lorsque le l'organe moteur (1) est remonté. L'organe moteur (1) a une réserve de marche supérieure aux organes moteurs conventionnels tout en ayant une longue durée de vie, et en maximisant la restitution de l'énergie emmagasinée.

Motor unit (1) for a watch movement comprising: a barrel (2) mounted on a shaft (3) so as to be rotatable about an axis (4) of the shaft (3) when the driving member (3) 1) is reassembled; a motor spring unit comprising first and second springs (8, 11) wound inside the barrel (2) superimposed and coaxial with each other, the first and the second spring (8, 11). ) being coupled at one end to the barrel (2) and to the shaft (3), respectively; the unit further comprising a plate (14) coaxially mounted between the two springs (8, 11); characterized in that the plate (14) is rotatably mounted on the axis (4); and in that the first and the second spring (8, 11) are coupled at their other end to the center (16) and the periphery (15) of the plate (14), respectively, so that the two springs (8, 11) arm simultaneously around the axis (4) when the motor member (1) is raised. The drive member (1) has a higher power reserve than conventional drive members while having a long life, and maximizing the return of stored energy.
