Claims

[Scope of utility model registration request]

The left and right side panels on which the treads are installed are divided vertically into four parts, and are formed separately into upper and lower portions of the upper and lower sections, and upper and lower sections of the lower section. The joint between the side plates and the joint between the side plates and the lower section are connected to each other by a joint hinge whose pivot axis is located at the back edge (or front edge) of the side panel, and the joint between the lower section of the upper section and the upper section of the lower section. A folding ladder characterized in that the joint parts between the partial side plates are connected to each other by joint hinges in which the pivot shafts are located at positions that extend backward from the rear edge of the side plates (or from the leading edge of the side plates by the width of the side plates).
