Abstract

Un dispositivo di chiusura, di tipo magnetico, comprende due parti, una delle quali (parte A) rappresenta la parte magneticamente attraente, mentre l'altra viene magneticamente attratta dalla parte A (considerata come parte B). La parte A include un magnete permanente con un foro centrale, un primo disco ferromagnetico e un involucro non magnetico con un foro centrale non allineato con un foro centrale del magnete permanente; la parte B include un secondo disco ferromagnetico che impegna il primo disco ferromagnetico. L'involucro non magnetico presenta una superficie ribassata su di un lato della quale il secondo disco impegna il primo disco e che fornisce una superficie di scorrimento per il secondo disco, per la guida verso i fori di centro dell'involucro e del magnete permanente. Uno spazio magnetico viene definito fra l'involucro e il magnete permanente. In conformità con l'invenzione è possibile ridurre il peso e semplificare la costruzione.(Figura 1).
