Abstract

Mezzi di sicurezza per macchinari azionati elettricamente comprendenti un guanto di sicurezza in tessuto metallico a maglia di tipo convenzionale, adattato in modo da poter essere indossato dall'operatore della macchina. La macchina con cui il guanto viene usato, è munita di un telaio collegato e massa, un motore elettrico ed un interruttore di comando, con il motore elettrico che è collegato ad una fonte di energia elettrica attraverso l'interruttore di comando. Il guanto in tessuto metallico a maglia dell'operatore è collegato all'antenna di un trasmettitore radio indossato dall'operatore stesso. I mezzi di interruzione del circuito includono mezzi radioriceventi che rimangono chiusi quando ricevono un segnale elettromagnetico, ad esempio un segnale radio, ma che si aprono quando l'antenna del trasmettitore radio viene messa a massa sul telaio tramite il guanto in tessuto metallico a maglia che tocca il telaio, il che serve ad interrompere la trasmissione del segnale. Ciò fa si che l'energia elettrica al motore si interrompa.
