Abstract

Dispositif de commande et de sécurité qui assure la protection des mains du conducteur d'une machine comportant une partie mobile dangereuse. Des moyens de temporisation électrique sont activés par les deux boutons-poussoir M1 et M2 quand le laps de temps écoulé entre les instants d'enfoncement de ces boutons dépasse un temps prédéterminé. Par activation de ceux-ci un circuit de commutation est alimenté qui commande alors les organes de mise en service de la partie mobile. Application : machine à partie mobile mue par des moyens hydrauliques, pneumatiques ou électriques.
