TELESCOPIC LADDER WITH TELESCOPIC HANDRAIL
To provide a ladder having a configuration which can be easily extended for use, can be easily shortened for storage at the time of recovery after use, and can also extend and contract a handrail body.SOLUTION: A ladder base member 101 including a pair of cylindrical strut bodies 110 and a horizontal cross-piece body 120 is used as a base unit, and the cylindrical strut bodies 110 of respective stages are successively connected slidably in the direction of a cylindrical axis, and a shortened storage state and an extended use state are provided. A lock mechanism 130 for temporarily fixing the ladder base members 101 so as not to be slidable and a lock release mechanism 140 for releasing the lock state of the lock mechanism 130 so as to be slidable are provided, and a cylindrical handrail body 150 is also assembled in a slidable manner. The handrail body 150 is also rotatable in the horizontal direction, and in the lock mechanism, a fitting pin 131 is fitted into a fitting hole 152 of the handrail body 150 while allowing the handrail body 150 to freely slide, extend, and rotate in the horizontal direction.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、手すり体も伸縮可能な構造を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、短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。梯子基本部材１０１同士の間に一時的に摺動不能に固定するロック機構１３０と、ロック機構１３０のロック状態を解除し、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も摺動可能に組み上げる。手すり体１５０が水平方向にも回動可能となっており、ロック機構において、手すり体１５０の摺動伸長の動きと水平方向の回動の動きを自在としつつ、嵌入ピン１３１が手すり体１５０嵌入孔１５２に嵌入される。【選択図】 図１
