STEP LADDER
To provide a step ladder on which an open stopper can be provided and which can easily change the standing condition into the closed condition, regardless of the size.SOLUTION: A step ladder 1 includes a pair of ladder bodies 2, 2 that have: two supporting pillars 3,3; multiple steps 4 that bridge between the supporting pillars 3,3; and a top board 5 that connects the ends of the supporting pillars 3,3. The ladder bodies are connected to each other on each end thereof in a relatively rotatable manner and are deformable into the closed condition where the ladder bodies 2, 2 are close and the step ladder condition where the ladder bodies 2,2 are separated with a predetermined interval therebetween, and have an opening stopper mechanism 7 that controls the relative displacement of the ladder bodies 2, 2 in the step ladder condition. The opening stopper mechanism 7 has a control releasing member 82 that releases the control of the relative displacement on the ladder bodies 2, 2 in the step ladder condition. The control releasing member 82 is attached to the ladder body 2 through a pair of brackets 81, 81 each provided on both ends of the ladder 2.SELECTED DRAWING: Figure 3
【課題】その大きさに関わらず開き止め機構を設けることができ、容易に脚立状態から閉状態とすることを可能とする、脚立を提供する。【解決手段】脚立１は、二本の支柱３・３と、支柱３・３の間に架け渡される複数の踏桟４と、支柱３・３の一端部を連結する天板５と、を備える一対の梯子体２・２が、互いの一端部で相対回転可能に連結され、梯子体２・２が近接した閉状態と、梯子体２・２が所定間隔に離間した脚立状態と、に変形可能であって、脚立状態において梯子体２・２の相対変位を規制する開き止め機構７を備え、開き止め機構７は、脚立状態の際に梯子体２・２における相対変位の規制を解除する規制解除部材８２を備え、規制解除部材８２は、梯子体２における両側にそれぞれ設けられた一対のブラケット８１・８１を介して梯子体２に組付けられる。【選択図】図３
