Abstract

Dispositivo (30) per manovra di interruttori (34), o simili, formato essenzialmente da una manopola rotativa (56), montata su un congegno di trasmissione e blocco (50) fissato ad una portella (52), dal quale congegno sporge verso l'interno della portella (52) un elemento di trasmissione autocentrante (44) mettente in comunicazione detta manopola (56) con un meccanismo (40) di trasformazione di movimento rotatorio in rettilineo, il dispositivo (30) consentendo di bloccare la portella (52) sia in caso di interruttore chiuso che di interruttore aperto con dispositivo lucchettato, impedendo inoltre la chiusura dell'interruttore in caso di portella (52) aperta. Inoltre, la manopola rotativa (56) mantiene memoria della posizione assunta prima di un'apertura di portella e l'elemento di trasmissione autocentrante (44) consente di compensare disallineamenti tra la manopola rotativa (56) e il meccanismo (40) di trasformazione di movimento di manovra dell'interruttore.
