To provide a hanging ladder which can be easily extended to use just by being hung and which can be easily shortened to store in a shortened storage state upon recovery at the end of use.SOLUTION: An telescopic hanging ladder is configured such that a plurality of ladder basic members 101 are prepared each of which, as a basic unit, includes a pair of cylindrical columns 110 and cross bars 122, the plurality of basic units are connected in series in a slidable manner in the axial direction of the cylindrical support 110 between the uppermost ladder basic member 101 to the lowermost ladder basic member 102, and a shortened storage state in which the ladder basic members 101 are contracted and an extended use state in which the ladder basic members 101 are expanded are provided. A telescopic operating body 150 is attached to the lowermost slidable ladder basic member 102 after passing through a hollow inside of the cylindrical column 110. Loosening the telescopic operating body 150 causes the lowermost slidable ladder basic member 102 to descend and pulling up the telescopic operating body causes the lowermost slidable ladder basic member 102 to ascend.SELECTED DRAWING: Figure 1
【課題】 吊り下げるだけで容易に伸長使用状態となり、使用終了時の回収時に簡単に短縮させて短縮収納状態にできる吊下梯子を提供する。【解決手段】 一対の筒状支柱体１１０と横桟体１２２を備えた梯子基本部材１０１を基本単位とし、最上段の梯子基本部材１０１から最下段の梯子基本部材１０２にかけて筒状支柱体１１０の筒軸線方向に摺動可能に順次接続し、梯子基本部材１０１を収縮した短縮収納状態と梯子基本部材１０１が伸長した伸長使用状態を持つ。伸縮操作体１５０が筒状体１１０の内部の中空を通って最下段の摺動可能な梯子基本部材１０２に取り付けられている。伸縮操作体１５０を緩めることで最下段の摺動可能な梯子基本部材１０２が下降し、伸縮操作体を引き上げることで最下段の摺動可能な梯子基本部材１０２が上昇する。【選択図】 図１
