Abstract

L'invention concerne une échelle pliante portable. Il comporte un élément central allongé et deux éléments extérieurs allongés disposés un sur chacun des côtés opposés de l'élément central. Des échelons sont rattachés à la fois à l'élément central et à un élément extérieur respectif, l'ensemble étant agencé pour se replier ou se déplier, avec des moyens déclenchables pour supporter les échelons dans leur position dressée. Une extrémité de l'échelle vient en contact du sol en deux points espacés, et un élément support repliable constitue un troisième point de support.
