Abstract:
PROBLEM TO BE SOLVED: To provide a portable working platform suited for use in a pipe space or other narrow spaces.SOLUTION: A portable working platform 1 includes a long ladder-like main leg 10, and a short supporting leg 20 arranged opposite the main leg 10 and supporting the main leg 10. An upper end of the supporting leg 20 is pivoted rotatably on a vertical part 11b of the main leg 10 through a rotary metal fitting 30. A protrusion 15 is formed on right and left upper ends of the main leg 10, or an upper end of each support post 11, the protrusion protruding almost horizontally in a direction toward the supporting leg 20 side. When using the portable working platform 1, the main leg 10 and the supporting leg 20 are opened around a rotary shaft of the rotary metal fitting 30, with the supporting leg 20 facing a wall. Here, when the portable working platform is used by opening the main leg 10 and the supporting leg 20 and hooking a pair of stopper metal fittings 40, the supporting leg 20 stands at an angle closer to perpendicular than a standing angle of the main leg 10, and supports the main leg 10.SELECTED DRAWING: Figure 2
