Abstract

UN PICAPORTE MAGNETICO INCLUYE UN PRIMER MIEMBRO (301) QUE TIENE UN SALIENTE Y UN SEGUNDO MIEMBRO (305) QUE ENGRANA CON EL SALIENTE PARA PREVENIR QUE EL PRIMER MIEMBRO (301) Y EL SEGUNDO MIEMBRO (305) SE DESLICEN EL UNO SOBRE EL OTRO RESPECTIVAMENTE. EL SEGUNDO MIEMBRO INCLUYE UN PRIMER IMAN (230) PARA ATRAER AL PRIMER MIEMBRO (301) Y UN PRIMER MIEMBRO SOLIDO NO MAGNETICO (319A) LOCALIZADO DENTRO DE UNA CAVIDAD DEL PRIMER IMAN (230) PARA AUMENTAR LA ATRACCION ENTRE EL PRIMER MIEMBRO (301) Y EL SEGUNDO MIEMBRO (305). EL SEGUNDO MIEMBRO (305) PUEDE SER PROVISTO CON UNA PLACA TRASERA (315A) PARA FACILITAR UN RECORRIDO DE FLUJO MAGNETICO DESDE EL IMAN HASTA LA ABERTURA DEL IMAN. EL SEGUNDO MIEMBRO (305) PUEDE TAMBIEN INCLUIR UN SEGUNDO IMAN PARA ATRAER AL PRIMER MIEMBRO (301) Y UN SEGUNDO MIEMBRO SOLIDO NO MAGNETICO LOCALIZADO ENTRE EL PRIMER IMAN Y EL SEGUNDO IMAN. UN TERCER MIEMBRO SOLIDO NO MAGNETICO PUEDE SER PROVISTO SOBRE LA PERIFERIA EXTERIOR DE LOS IMANES. ESTE DISEÑO PROPORCIONA UN PICAPORTE CON POTENCIA DE AGARRE MAS FUERTE.
