Abstract
L'invention concerne un module d'échelle pliante portable. Il comporte un élément central allongé et deux éléments extérieurs disposés un sur chacun des côtés de l'élément central. Des échelons sont attachés à l'élément central et à un élément extérieur respectif. Les éléments extérieurs avec leurs échelons peuvent être repliés et dépliés. Le module est muni de premier et second moyens d'engagement coopérant entre eux de telle sorte qu'un ensemble de tels modules puisse être assemblé sous la forme d'une échelle de plus grande longueur que le module.
