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
【課題】パイプスペース等の狭小空間で利用するのに好適な可搬式作業台を提供する。【解決手段】可搬式作業台１は、梯子状の長尺の主脚１０と、主脚１０に対向するように配置され、主脚１０を支える短尺の支持脚２０とを備え、支持脚２０の上端が、主脚１０の垂直部１１ｂに回動金具３０を介して回動自在に軸着される。また、主脚１０の左右上端、すなわち各支柱１１の上端には、支持脚２０側の方向に略水平に突出する突出部１５が設けられる。可搬式作業台１を使用するときは、回動金具３０の回動軸を中心として主脚１０と支持脚２０とを開いて、支持脚２０を壁に向ける。ここで、主脚１０と支持脚２０とを開いて、一対の開き止め金具４０を掛け渡す使用状態では、支持脚２０は、主脚１０が立つ角度よりも垂直に近い角度で立って主脚１０を支える。【選択図】図２
