PROBLEM TO BE SOLVED: To provide a ladder fall prevention device that can extremely easily be mounted in a ladder, and can prevent a worker on the ladder from falling on the ground by supporting the ladder from the lower part when the ladder is turned over.SOLUTION: A ladder fall prevention device includes: an upper member 10 capable of being mounted on an upper surface of a landing peg 70 of a ladder 200; a lower member 20 for covering the lower surface of the landing peg 70; a connecting member 30 for connecting the upper member 10 with the lower member 20 so that the landing peg 70 may come in and out between the upper member 10 and the lower member 20; and a rod member 50 extended from the lower member 20 to the lower part. A longitudinal length of the lower member 20 is formed longer than the longitudinal length of the upper member 10, and the ladder 200 is supported from the lower part by the lower member 20 and the rod member 50 when the ladder 200 is turned over.SELECTED DRAWING: Figure 3
【課題】極めて簡単に梯子に取り付けることができるとともに、梯子が転倒した際に、梯子を下方から支えることで、梯子上の作業者が地面に落下するのを防止することのできる梯子転倒防止具を提供する。【解決手段】梯子２００の踏桟７０の上面に載置可能な上側部材１０と、踏桟７０の下面を覆う下側部材２０と、上側部材１０と下側部材２０の間に踏桟７０が出入り可能となるよう、上側部材１０と下側部材２０を連結する連結部材３０と、下側部材２０から下方に延設される棒部材５０とを備え、下側部材２０の前後方向の長さを、上側部材１０の前後方向の長さよりも長く形成し、梯子２００が転倒した際、下側部材２０と棒部材５０によって、梯子２００を下方から支える。【選択図】図３
