PROBLEM TO BE SOLVED: To guide an escape in a short time, by quickly bringing into at evacuation time, by making an evacuation ladder easily portable.SOLUTION: An evacuation ladder 2 comprises a guide frame 6, a ladder body 5 stored so as to freely advance-retreat from the lower end of the guide frame 6, a stopper mechanism 23 for locking the ladder body 5 to the guide frame 6 and a handrail 30 collapsibly connected to the guide frame 6. In use, the ladder body 5 is locked by projecting a desired dimension L3 from the lower end of the guide frame 6, and an upper end locking part 15 of the guide frame 6 is locked on a door floor 4 of a railway vehicle 3, and the lower end of the projected ladder body 5 is grounded on a track bed, and the evacuation ladder 2 is installed by inclining at a desired angle α, and the handrail 30 is stood up from the guide frame 6.SELECTED DRAWING: Figure 1
【課題】避難用梯子を持ち運びしやすくし、避難時、迅速に持ち込み、脱出誘導を短時間で行う。【解決手段】避難用梯子2は、ガイド枠6と、ガイド枠6の下端から進退自在に収容された梯子体5と、梯子体5をガイド枠6に対してロックするストッパ機構23と、ガイド枠6に折り畳み可能に連結された手摺30とを備えて構成される。使用時には、梯子体5をガイド枠6下端から所望の寸法L3突出させてロックし、ガイド枠6上端の係止部15を、鉄道車両3の扉床4に係止させ、突出された梯子体5の下端を軌道道床に接地させて、避難用梯子2を所望の角度αに傾斜させて設置し、手摺30をガイド枠6から起立させるようになっている。【選択図】図1
