Abstract

The ladder has hinges (4) which form pivot axes (5) which are parallel and form an angle (alpha) with a plane extending at right-angles towards the longitudinal direction of side pieces (1,2). This permits collapse of the ladder steps by relative movement between the side pieces so that they are located in planes arranged relatively near to each other. A foot step (3) reciprocal clearance (H), viewed in the ladder usage position, together with its depth (D), is such that when the ladder is collapsed the steps are located at the side of each other in a parallel relationship in the same plane.
