STEP LADDER USABLE AS LADDER
To provide a step ladder usable as a ladder, which can be easily closed from a step ladder state.SOLUTION: A step ladder 1 is formed of a pair of ladder bodies 2, 2, which have two poles 3, 3, a plurality of rungs 4 that are laid across the poles 3, 3, and a top board 5 for connecting one end of the poles 3, 3, and are connected at their one ends so as to be relatively rotatable. The step ladder can be deformed into a closed state in which the ladder bodies 2, 2 come close to each other, a step ladder state in which the ladder bodies 2, 2 are spaced away from each other at predetermined interval, or a ladder state in which the ladder bodies 2, 2 are opened at 180 degrees. The step ladder has an opening prevention mechanism 7 that restricts the relative displacement between the ladder bodies 2, 2 in the step ladder state or the ladder state. The opening prevention mechanism 7 has a restriction release member 82 that releases the restriction of the relative displacement of the ladder bodies 2, 2 in the step ladder state.SELECTED DRAWING: Figure 4
【課題】容易に脚立状態から閉状態とすることが可能となる、梯子兼用脚立を提供する。【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、梯子体２・２が１８０度開かれた梯子状態と、に変形可能であって、脚立状態又は梯子状態のそれぞれにおいて梯子体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を備える。【選択図】図４
