Abstract

Una cerradura accionable por imán permanente, dotada de un elemento de bloqueo movible por fuerza magnética, y de una llave de imán permanente a través de la cual el elemento de bloqueo puede ser movido de una posición de fuera de servicio a una posición de servicio para ejercer una función de bloqueo y de liberación, respectivamente, y que está constituida por un cuerpo magnético en forma de disco y hecho de material magnético permanente de una permeabilidad magnética relativamente pequeña y dotado de imantaciones locales, caracterizada porque el cuerpo magnético presenta las imantaciones locales en forma de cortos dipolos magnéticos (N - S) situados en la proximidad de la superficie y sustancialmente paralelos con respecto a la misma, siendo el largo (separación de polos) de los dipolos inferior a unos 2 mm.
