TELESCOPIC HANGING LADDER
To provide a hanging ladder which can be easily extended and used simply by suspending it, and can be easily shortened at the time of collection at the end of use to be in the short storage state.SOLUTION: A ladder basic member 101 including a pair of cylindrical support members 110 and a horizontal cross member 122 is used as a basic unit, and connected slidably in sequence from the uppermost ladder basic member 101 to the lowermost ladder basic member 101 in the axial direction of the cylindrical support member 110. A ladder body has a shortened storage state in which the ladder basic member 101 is contracted and an extended use state in which the ladder basic member 101 is expanded. A hanging ladder has a locking mechanism 130 which temporarily locks in a non-slidable manner when the ladder basic members at the lower and upper stages are in extended use and a lock release mechanism 140 which releases the lock state of the locking mechanism 130 in response to an operation from the outside such as a collision of the lower horizontal beam, and makes the ladder basic members of the stage and the lower stage slidable. A telescopic operating body 150 is attached to the lowermost lock release mechanism 140 so as to be operable, and the lowermost stage is operable as a free cross rail.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１０１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。当段と下段の梯子基本部材同士が伸長使用状態になれば一時的に摺動不能に固定するロック機構１３０と、下段の横桟の衝突など外部からの操作を契機としてロック機構１３０のロック状態を解除し、当段と下段の梯子基本部材同士を摺動可能にするロック解除機構１４０を備え、最下段のロック解除機構１４０に伸縮操作体１５０を取り付けて操作可能とし、また、最下段を自由横桟として操作可能とする。【選択図】 図１
