Abstract

Se proporciona una escalera que tiene una sección de base y una sección de mariposa acoplada de manera deslizable con la sección de base. La sección de base incluye un primer par de pasamanos separados y una primera pluralidad de peldaños que se extiende entre y se acopla al primer par de pasamanos separados. La sección de mariposa incluye un segundo par de pasamanos separados y una segunda pluralidad de peldaños que se extienden entre y se acopla al segundo par de pasamanos separados. Los diversos peldaños pueden acoplarse con sus pasamanos asociados en una relación de desplazamiento de manera que no se centren a lo largo de una línea de eje central longitudinal de los pasamanos. Un dispositivo de bloqueo de peldaño puede utilizarse el cual incluye un brazo acoplado de manera pivotante con la sección de base y configurado para acoplar de manera selectiva varios peldaños de la segunda pluralidad de peldaños para mantener la sección de mariposa en una posición deseada con respecto a la sección de base.
