HOOK DEVICE AND FALL PREVENTION TOOL FOR SCAFFOLD
To provide a hook device and a fall prevention tool for a scaffold capable of easily suppressing falling of an insertion member inserted into a recessed part of the hook device and easily removing the insertion member.SOLUTION: A hook device 18B is provided with a portion of a hook body 22 opposite to the tip of a curved part 22b with a recessed part interposed therebetween and a recessed part opening/closing member 29 to which both ends are connected between a swing arm 26. The recessed part opening/closing member 29 moves to a recessed part closing position for closing the recessed part in cooperation with the swing arm 26 when the swing arm 26 moves to the closing position, and moves to a recessed part opening position for opening the recessed part when the swing arm 26 moves to the opening position.SELECTED DRAWING: Figure 1
【課題】フック装置の凹部内に挿通した挿通部材の脱落の抑制及び挿通部材の取り外しがしやすいフック装置及び足場用落下防止具を提供する。【解決手段】フック装置１８Ｂは、フック本体２２において、湾曲部２２ｂの先端とは凹部を挟んで反対側の部位と、揺動アーム２６との間に両端が連結された凹部開閉部材２９を備える。凹部開閉部材２９は、揺動アーム２６が閉鎖位置へ移動するときは、揺動アーム２６と協働して凹部を閉鎖する凹部閉鎖位置に移動し、揺動アーム２６が開放位置へ移動するときは凹部を開放する凹部開放位置に移動する。【選択図】図１
