To provide a ladder for evacuation which can be easily deployed in evacuation while keeping a ladder body compact by folding a handrail to be in an overlap relation to the ladder body.SOLUTION: A ladder 100 includes: a pair of cylindrical support bodies 110 for supporting both ends of an elevating surface; a ladder body provided between the cylindrical support bodies 110 and having horizontal beams 120; a handrail body 140 supported in parallel with the elevating surface of the ladder body; a connecting body 150 connecting between the handrail body 140 and the cylindrical support body 110 to support the handrail body 140; a first rotating body 160-1 rotatably connected from a parallel state with respect to the elevating surface to a vertical state therewith at a connection part with the cylindrical support body 110; and a second rotating body 160-2 rotatably connected from a parallel state with respect to the elevating surface to a vertical state therewith at a connection part with the handrail body 140. The first rotating body 160-1 and the second rotating body 160-2 are identical in rotation angle, and the handrail body 140 can separate from and approach the cylindrical support body 110 while keeping the parallel state thereto.SELECTED DRAWING: Figure 1
【課題】 手摺りを梯子本体に重なるように折り畳んでコンパクトに抑えつつ、避難時に容易に展開できる避難用の梯子を提供する。【解決手段】 梯子１００は、昇降面の両端を支持する一対の筒状支柱体１１０と、筒状支柱体１１０の間に設けられた横桟１２０を備えた梯子本体と、梯子本体の昇降面と平行に支持された手摺り体１４０と、手摺り体１４０と筒状支柱体１１０との間を接続して手摺り体１４０を支持する接続体１５０と、筒状支柱体１１０との接続箇所で昇降面に対して平行状態から垂直状態まで回動可能に接続する第１の回動体１６０−１と、手摺り体１４０との接続箇所で昇降面に対して平行状態から垂直状態まで回動可能に接続する第２の回動体１６０−２を備えている。第１の回動体１６０−１と第２の回動体１６０−２の回動角が同一で、手摺り体１４０が筒状支柱体１１０に対して平行を保ったまま離隔・接近が可能となっている。【選択図】 図１
