To provide a ladder that can be easily extended and used, can be easily shortened at the time of collection at the end of use, can be shortened and stored, and can be gripped during use.SOLUTION: A ladder basic member 101 provided with a pair of cylindrical struts 110 and a horizontal crosspiece 120 is a basic unit, and the cylindrical support columns 110 at each stage are sequentially connected so as to be slidable in the cylinder axis direction, and have a contracted and retracted storage state and an extended and extended use state. It comprises a lock mechanism 130 for temporarily non-slidably fixing the upper and lower ladder basic members when they are in an extended use state, and a lock release mechanism 140 that releases the lock state of the lock mechanism 130 through the operation of the operation lever and allows the ladder basic members of the current stage and the lower stage to slide with each other, and furthermore, the cylindrical handrail body 150 is assembled so as to be slidable with respect to the uppermost cylindrical support body. As a mechanism in which the insertion pin of the lock mechanism 130 penetrates the handrail body 150, the handrail body 150 has a stable structure when extended.SELECTED DRAWING: Figure 1
【課題】 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、使用時に把持できる手すり体も備えた梯子を提供する。【解決手段】 一対の筒状支柱体１１０と横桟体１２０を備えた梯子基本部材１０１を基本単位とし、各段の筒状支柱体１１０を筒軸線方向に摺動可能に順次接続し、収縮した短縮収納状態と伸長した伸長使用状態を持つものとする。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、操作レバーの操作を介してロック機構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、さらに筒状の手すり体１５０を最上段の筒状支柱体に対して摺動可能に組み上げる。手すり体１５０に対してロック機構１３０の嵌入ピンが貫通する仕組みとして伸長時に手すり体１５０が安定した構造とする。【選択図】 図１
