Abstract

The present invention relates to a foldable stepladder constituted by: a first pair of two main uprights, a plurality of steps, a device for maintaining said steps in their unfolded configuration, a second pair of two auxiliary uprights, wherein the auxiliary uprights are articulated at one of their ends on the upper part of the main uprights and they are articulated on each other about a pin in their median part to present, in unfolded position of use, the form of a cross, said auxiliary uprights being connected from said mutual pivot point to the central upright by a connecting rod. The invention is more particularly applicable to the manufacture of foldable stepladders.
