TELESCOPIC LEG DEVICE, AND LADDER BODY

To provide a telescopic leg device of a ladder body including a remote control mechanism for facilitating expanding/contracting work of a telescopic leg member with an easy posture, which is lighter and easier to transport.SOLUTION: A telescopic leg device 5 includes: a telescopic leg member 6 that is slidably connected to a pillar 3 and constitutes a leg of the ladder body 2; a lock mechanism 7 that can lock the telescopic leg member 6 at a desired sliding position relative to the pillar 3; and a remote control mechanism 8 for remote controlling the lock mechanism 7. The lock mechanism 7 has: a locked part 71 that is formed in the telescopic leg member 6 along the length direction thereof; and a locking member 72 that is provided in the bottom of ladder body 2 and is switchable between a locked state engaged with the locked part 71 and an unlocked state where the engagement with the locked part 71 is released. The remote control mechanism 8 has a rotating member 9, an operation part 10, and a lower transmission part 11 that transmits the rotational movement of the rotating member 9 to the locking member 72 to switch the locking member 72 to an unlocked state.SELECTED DRAWING: Figure 4 【課題】伸縮脚部材の伸縮作業を楽な姿勢で簡単に行うための遠隔操作機構を備えた梯子体の伸縮脚装置として、より軽量であって、運搬性が向上するものを提供する。【解決手段】伸縮脚装置5は、支柱3にスライド自在に連結されて梯子体2の脚を構成する伸縮脚部材6と、伸縮脚部材6を支柱3に対して任意のスライド位置でロックしうるロック機構7と、ロック機構7を遠隔操作するための遠隔操作機構8とを備えている。ロック機構7が、伸縮脚部材6にその長さ方向に沿って形成されている被係止部71と、梯子体2の下部に設けられかつ被係止部71と係合するロック状態および被係止部71との係合が解除されるロック解除状態の間で切り替え可能な係止部材72とを有している。遠隔操作機構8が、回転部材9と、操作部10と、回転部材9の回転動作を係止部材72に伝達して係止部材72をロック解除状態に切り替える下部伝達部11とを有している。【選択図】図４
