ESCAPE LADDER DEVICE
PROBLEM TO BE SOLVED: To provide an escape ladder device capable of easily correcting the position of a handle on site if the handle associated with a release mechanism does not correspond positionally to an escape passage such as a building window.SOLUTION: An escape ladder device includes a fixing piece 11 to be fixed to a building, a movable piece 12 arranged in parallel with the fixing piece, a plurality of ladder steps 13 spanned between the fixing piece 11 and the movable piece 12 in a pivotal manner, a lock mechanism 6 and 7 for maintaining an accommodated state under which the ladder steps 13 are folded for accommodation, an unlock mechanism 26 and 28 for releasing a locked state of the locking mechanism 6 and 7, a rotational shaft 22 causing the unlock mechanism 26 and 28 to operate and detachably attached to the releasing mechanism, and a handle H that causes the rotational shaft 22 to rotate, and further includes a plurality of shaft holes 11g into which the rotational shaft 22 is inserted are pre-formed in a lengthwise direction of the fixing piece 11.SELECTED DRAWING: Figure 1
【課題】 解除機構に連係させたハンドルと建物の窓などの避難路との位置が対応していなかったとしても、現場で簡単にハンドルの位置を修正できる避難用はしご装置を提供すること。【解決手段】 建物に固定する固定柱１１と、この固定柱に沿って配置された可動柱１２と、固定柱１１と可動柱１２との間に回動自在にかけ渡された複数のはしご用桟１３と、はしご用桟１３が折り畳まれて収納される収納状態を維持するロック機構６，７と、ロック機構６，７のロック状態を解除する解除機構２６，２８と、この解除機構２６，２８を動作させるとともに、この解除機構に対して着脱可能にされた回転軸２２と、この回転軸２２を回転させるハンドルＨとが備えられるとともに、上記回転軸２２を挿入するための複数の軸孔１１ｇが固定柱１１の軸方向に沿って予め形成されている。【選択図】 図１
