PROBLEM TO BE SOLVED: To enhance efficiency of work by enclosing a work space above a top plate.SOLUTION: A stepladder type working platform comprises a pair of main legs 10a and 10b rotatably journaling an upper part and inclining to the outside toward the lower side, a top plate 20 installed between the pair of main legs 10a and 10b, and a first frame member 30 and a second frame member 40 for enclosing a work space S above the top plate 20. The first frame member 30 is formed in a substantially U shape, and both end parts on its opening part side are supported by the main leg 10a, and are arranged so as to lay down to the top plate 20, and are positioned in a height H1 on the main leg 10b side. The second frame member 40 is formed in a substantially U shape, and both end parts on its opening part side are supported by the main leg 10a, and are arranged so as to stand up more than the first frame member 30, and are positioned higher than the height H1 on the main leg 10a side.SELECTED DRAWING: Figure 2
【課題】天板の上方の作業空間を包囲することにより作業の効率化を図る。【解決手段】上部が回動自在に軸着され、下側に向かって外側に傾斜する一対の主脚１０ａ、１０ｂと、一対の主脚１０ａ、１０ｂ間に架設される天板２０と、天板２０の上方の作業空間Ｓを包囲する第１の枠部材３０及び第２の枠部材４０とを備える。第１の枠部材３０は、略コ字状に形成されており、その開放部側の両端部が主脚１０ａで支持され、天板２０に対して寝かせるように配置されて、主脚１０ｂ側で高さＨ１に位置する。第２の枠部材４０は、略コ字状に形成されており、その開放部側の両端部が主脚１０ａで支持され、第１の枠部材３０よりも立たせるように配置されて、主脚１０ａ側で高さＨ１よりも高く位置する。【選択図】図２
