Claims

[Scope of utility model registration request]

Attach several sets of gap crosspieces 21 at appropriate intervals between the left and right base frames 11, 11 whose legs are spread downward, facing each other in the front and back, and bend the tops of the base frames 11 and 11 further forward to attach the top plate. 13 is attached, a top plate part B is provided to form a base part A, left and right support girders 21°21 are arranged in a tapered shape on the front part of the top plate part B, and footrests 22... are installed in appropriate positions. The bases of the horizontal parts C installed at intervals are rotatably connected, and a lever D is attached to the base part A and the horizontal part C to freely limit the opening of the base part A and the horizontal part C. In the folding ladder formed so as to be able to move, the base of the horizontal part C is removably connected, and the base of the crutch-shaped supporting leg E is rotatably attached to the front part of the top plate part B. Its distinctive feature is the structure of a folding ladder with a top plate attached to the base.
