Abstract

CERRADURA OPERADA POR LLAVE DE TARJETA MAGNETICA. INCLUYE UN NUCLEO CORREDIZO DOTADO DE UNA PLURALIDAD DE AGUJEROS QUE RECIBEN CERROJOS CONSTITUIDOS POR IMANES CILINDRICOS, IMPIDIENDO SU MOVIMIENTO HASTA QUE NO SE INTRODUCE LA LLAVE MAGNETICA CORRECTA QUE PERMITA REPELER LOS MISMOS. LOS IMANES TIENEN EN UN EXTREMO UNA INTENSIDAD DE MAGNETIZACION MENOR EN EL EXTREMO OPUESTO, LO QUE SE OBTIENE PARTIENDO DE UN IMAN CONVENCIONAL (14) QUE SE CONECTA POR UN EXTREMO AL EXTREMO OPUESTO DE OTRO IMAN (30), APLICANDO UN CAMPO MAGNETICO (32, 34) AL PRIMERO Y DESMONTANDO EL MISMO PARA INVERTIR LA POLARIDAD DEL EXTREMO OPUESTO. ESTA FUERZA DE IMANTACION MENOR EN UN EXTREMO PERMITE COLOCAR LOS IMANES PROXIMOS ENTRE SI SIN QUE SE INFLUENCIEN MUTUAMENTE PROVOCANDO UN MOVIMIENTO NO DESEADO O IMPIDIENDO UNO CORRECTO.
