Abstract

Un dispositivo di chiusura, di tipo magnetico, fornisce una attrazione magnetica potente per mezzo dello sfruttamento integrale delle linee magnetiche di forza associate ad un magnete permanente, senza provocare una saturazione magnetica.Questo dispositivo comporta una parte A che sviluppa l'azione di attrazione magnetica ed una parte B che viene magneticamente attratta. La parte A include un magnete permanente, un primo disco ferromagnetico unito ad un lato del magnete permanente ed un involucro non magnetico, mentre la parte B include un secondo disco ferromagnetico collegabile, con possibilità di distacco, all'altro lato del magnete permanente e presentante una astina ferromagnetica atta all'inserimento nei fori centrali del magnete permanente e dell'involucro. Il dispositivo include pure mezzi per aumentare il magnetismo nel punto in cui il primo e/o il secondo disco e l'astina, o le astine ferromagnetiche sono collegate.(Figura 1).
