Abstract

Dispositivo de unión y guía para elementos plegadores individuales de un reflector de antena plegable de tipo rígido; constituido por un panel central y por segmentos de plegadura que en éste último están dispuestos por medio de unas articulaciones caracterizado porque los extremos exteriores de los segmentos de plegadura están unidos entre si a través de unas articulaciones dispuestas en los mismos por medio por lo menos de una barra de unión que guía los segmentos de plegadura individuales de una forma definida durante el despliegue y que fija los mismos al encontrarse éstos en la posición definitiva.
