Abstract

ASEGURADOR DE CIERRE CON MEMORIA DE FORMA. UN ASEGURADOR DE CIERRE (16) INCLUYE UN COLLARIN TUBULAR (18) QUE POSEE UNA PLURALIDAD DE PROTUBERANCIAS (28, 40) QUE SE EXTIENDEN RADIALMENTE HACIA ADENTRO DESDE UNA SUPERFICIE INTERNA (22) DEL MISMO Y QUE ESTAN ADAPTADAS PARA QUE COOPEREN CON UN PERNO (14) PARA RETENER AL COLLARIN (18) EN SU LUGAR. UN ANILLO DE CIERRE (38) RODEA A UNA SUPERFICIE EXTERNA (20) DEL COLLARIN (18) Y POSEE UN DIAMETRO INTERNO INICIAL. EL ANILLO DE CIERRE (38) ESTA FORMADO POR UNA ALEACION DE METAL CON MEMORIA DE FORMA QUE ES EFECTIVA PARA QUE SE CONTRAIGA EL ANILLO DE CIERRE (38) HASTA QUE ADQUIERA UN DIAMETRO INTERNO FINAL QUE ES MENOR QUE EL DIAMETRO INTERNO INICIAL CON EL CAMBIO EN SU TEMPERATURA Y A SU VEZ PARA QUE CONTRAIGA AL COLLARIN (18) DE MANERA QUE RODEE A LAS PROTUBERANCIAS ESTABLECIENDO UN CONTACTO DE CIERRE CON EL PERNO (14).
