Abstract

Un tambour tournant (1) monté sur la plaque (10) d'un monte-charge ou similaire et solidaire du pignon (11) qui coopère avec la crémaillère (12), est muni de cames profilées (2 et 3) qui éloignent le galet (8) prévu à l'extrémité du levier (6) à l'encontre du ressort de rappel (9). Le levier est obligé de se soulever au moment opportun, avant le passage des saillies (4 et 5), lorsque le mouvement de rotation du tambour (1) est normal, tandis que son talon (6′) se bloque contre l'une des sail­ lies (4, 5) lorsque la vitesse de rotation dépasse une limite pré-­ établie prévue réglable.
