Abstract

Escalera portátil:está constituida por dos estructuras unidas en su Darte superior por un eje común: la anterior (C) posee una abertura longitudinal (R) en ambos lados por las cuales se desplazan unos peldaños móviles (A) donde se sitúan los pies. También posee en su parte frontal orificios en los que quedarán sujetos,al subir o bajar, dichos peldaños. Tiene en su interior unas gomas elásticas, etc., con las cuales facilitar la subida de los peldaños. Posee en su parte inferior dos patas de sujeción (unidas a ella permanentemente o no) y en la superior unos asideros. La estructura posterior tiene una o dos patas, permanentemente unidas o no. Esta escalera evita el tropiezo y la caída desde ésta, con menor coste de fabricación, utilizable por cualquier persona, incluso discapacitados.Portable ladder: it is made up of two structures joined on its upper side by a common axis: the previous one (C) has a longitudinal opening (R) on both sides through which moving steps (A) move where the feet are placed. It also has holes in its front part where these steps will be attached, when raising or lowering. It has elastic bands inside, etc., with which to facilitate the rise of the steps. It has two lower support legs (permanently or not attached to it) and upper handles. The posterior structure has one or two legs, permanently attached or not. This ladder prevents tripping and falling from it, with a lower manufacturing cost, usable by anyone, even the disabled.
