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 e 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.
