PROBLEM TO BE SOLVED: To provide a stepladder that may also be used as a work bench.SOLUTION: A stepladder 1 has a pair of right and left first and second leg parts 8, 11 placed to face each other at a top edge part and connected, the first and the second leg parts 8, 11 respectively comprising an upper ladder frame 2 and a lower ladder frame 4 connected to enable folding in two, and an upper ladder frame 3 and a lower ladder frame 5 connected to enable folding in two. A support shaft 14 is fitted horizontally on a top edge part and a rod-like engaged member 16 horizontally on a bottom edge part of the lower ladder frame 4, while a support shaft 15 is fitted horizontally on a top edge part and a rod-like engaged member 17 horizontally on a bottom edge part of the lower ladder frame 5. An edge side in a longer-side direction of rectangular tread boards 18, 19 is respectively pivoted rotatably on a right side of the support shaft 14 and a left side of the support shaft 15. When used as a stepladder, engaging means 60, 61 on the other edge side of the tread boards 18, 19 are engaged with the engaged members 17, 16. When used as a work bench, the stepladder 1 is folded in four and the engaging means 60, 61 on the other edge side of the tread boards 18, 19 are engaged with the support shafts 15, 14.SELECTED DRAWING: Figure 3
【課題】 １つの脚立を作業台と兼用可能とする。【解決手段】 左右一対の第１、第２の脚部８、１１の上端部を向かい合わせ、連結した脚立１において、第１、第２の脚部８、１１を各々、２つ折り自在に連結した上部梯子枠２と下部梯子枠４、２つ折り自在に連結した上部梯子枠３と下部梯子枠５から構成する。下部梯子枠４の上端部に水平に支軸１４、下端部に水平に棒状の被係合部材１６、下部梯子枠５の上端部に水平に支軸１５、下端部に水平に棒状の被係合部材１７を取着する。長方形状の踏み板１８、１９の各々の長手方向の一端側を支軸１４の右側、支軸１５の左側に回動自在に軸支させる。脚立使用時は、踏み板１８、１９の他端側の係合手段６０、６１を被係合部材１７、１６に係合し、作業台使用時は、脚立１を四つ折りし、踏み板１８、１９の他端側の係合手段６０、６１を支軸１５、１４に係合する。【選択図】 図３
