Abstract

L'invention concerne un dispositif de sécurité pour outils à main (1) à moteur électrique, notamment scies circulaires et scies alternatives, le mouvement du moteur étant transmis à l'outil (5) disposé sur un support (4), au moyen d'un disque d'embrayage avec un embrayage (10). Ce dispositif de sécurité (1) comprend un circuit détecteur électronique (SUS) avec une commande par aimant de levage (HS) qui, lorsque l'outil (5) vient en contact avec une partie du corps de l'utilisateur, sépare le moteur d'entraînement (8) de l'outil, par désengagement magnétique de l'embrayage. L'invention vise à créer un dispositif de sécurité permettant un réengagement aisé, sans danger pour l'utilisateur. A cet effet, l'embrayage désengageable peut être muni d'éléments d'embrayage (13, 16) pivotant dans le sens radial ou pouvant se déplacer dans le sens axial, ces éléments étant déplacés ou soulevés au moyen d'un aimant de levage (15), une fois ce dernier excité, hors des sièges (11, 25) créant le flux de force.
