EVACUATION LADDER
PROBLEM TO BE SOLVED: To provide an evacuation ladder capable eliminating operation to expand a guard fence while reliably getting into an expansion state to ensure swift and safety evacuation.SOLUTION: An evacuation ladder includes: a ladder part A which is constituted of a fixed post 11 fixed to a building and a movable post 12 to which plural ladders 13 are bridged between the fixed post 11; and a guard fence part B which is constituted of the movable post 12 and a rail post 15 having plural horizontal members 14 which are bridged between the movable post 12, in which when the rail post 15 is caused to get closer to the movable post 12, the horizontal members 14 are rotated and folded. In a state the horizontal members 14 are stored, the opposite distance between the rail post 15 and the movable post 12 are separated away from each other larger than a state of close contact of the rail post 15 and the movable post 12. The horizontal members 14 maintains an angle with respective a vertical line.SELECTED DRAWING: Figure 1
【課題】 防護柵を展開させる操作の手間を省略でき、避難時には、必ず防護柵が展開状態となって、より安全に速やかに避難できる避難用はしごを提供すること。【解決手段】 はしご部Ａが、建物に固定する固定柱１１と、固定柱１１との間に複数のはしご用桟１３がかけ渡される可動柱１２とから構成され、防護柵部Ｂは、上記可動柱１２と、この可動柱１２との間に複数の横材１４がかけ渡される柵用柱１５とから構成され、上記柵用柱１５を可動柱１２に接近させることによって、上記横材１４が回動しながら折りたたまれる避難用はしごを前提とし、上記横材１４の収納状態で、上記柵用柱１５と可動柱１２との対向間隔は、これら柵用柱１５と可動柱１２との密着状態よりも離れた間隔を保って、上記横材１４が鉛直線に対して角度を維持している。【選択図】 図１
