Abstract
Una escalera portatil, del tipo de tijera, que se caracteriza porque los largueros tienen perfil en U y tambien los peldaños, estando el testero de cada peldaño unido al larguero correspondiente por dentro de la U de éste, mediante atornillado o remachado, en tres caras del perfil en U de cada uno de ellos, teniendo cada peldaño en su cara inferior nervios longitudinales que le dan mayor resistencia a la flexión bajo carga, y porque en su extremo superior, cada par de largueros tiene un peldaño y ambos peldaños yuxtapuestos, al abrirse la escalera, forman una amplia plataforma, teniendo uno de los peldaños un tope a cada lado el cual coopera con una prolongación del herraje del otro peldaño para impedir la apertura excesiva de la escalera.
