Abstract

Un aparato de escalera tiene una primera sección de escalera que tiene un par de rieles laterales y una pluralidad de peldaños que se extienden entre los rieles laterales, una segunda sección de escalera conectada en forma articulada con la primera sección de escalera contigua a un extremo superior de la primera sección de escalera y un mecanismo de cerrojo fijo a una de las secciones de escalera y que se puede engranar con la otra de la primera y segunda secciones de escalera. La segunda sección de escalera es móvil entre la posición extendida y una posición retraída. El mecanismo de cerrojo está adaptado para asegurar la segunda sección de escalera en la posición retraída. La segunda sección de escalera se extiende en una relación generalmente paralela a la primera sección de escalera cuando está en esta posición retraída. Una parte superior de la escalera está fija al extremo superior de la primera sección de escalera y se extiende hacia el exterior desde el mismo de manera tal que tenga una superficie de extremo posicionada alejada de la primera sección de escalera.
