OVERTURN PREVENTION DEVICE FOR STEPLADDER
To provide a lightweight overturn prevention device for a stepladder, which is versatile enough to be attached to various stepladders, and does not have a configuration that prevents horizontal installation between supports.SOLUTION: An overturn prevention device 1 for a stepladder is attached to the lower end of a stepladder support 50. The overturn prevention device 1 for the stepladder is configured by combining an accommodating portion 2 for housing the support 50 and a flat base portion 4 extending in the width direction of the ladder. An opening 2a is formed in the horizontal direction of the accommodating portion 2. The opening 2a is connected to a cutout 2b on the upper surface for accommodating the support 50 in a split manner. The upper portion of the opening 2a can be closed by a closing portion 6. A screw shaft 8a of a pressing portion 8 that can press the side of the support 50 is screwed into the side surface of the accommodating portion 2 in the width direction. The accommodating portion 2 is assembled to the base portion 4 in a state in which a restoring force is accumulated by squeezing a slit 2c on the bottom surface and the cutout 2b on the top surface so as to reduce the opening 2a in the horizontal direction.SELECTED DRAWING: Figure 2
【課題】多様な脚立に対して取付可能な汎用性を有し、且つ、支柱の間に水平設置の妨げとなる構成を有さない、軽量な脚立用転倒防止具を提供する。【解決手段】脚立用転倒防止具１は脚立の支柱５０の下端に取り付けられる。この脚立用転倒防止具１は、支柱５０を収容する収容部２と梯子の幅方向に広がった平坦な基部４とを組み合わせて構成されている。収容部２の水平方向には開口２ａが形成されている。開口２ａは支柱５０を割り入れるように収容する上面の切り欠き２ｂと繋がっている。開口２ａの上方は閉鎖部６で閉じることが可能である。収容部２の幅方向の側面には、支柱５０の側方を押圧できる押圧部８のネジ軸８ａが螺合されている。収容部２は、開口２ａを水平方向へ縮小するように、底面のスリット２ｃと上面の切り欠き２ｂとを絞り、復元力を蓄えた状態で基部４に組み付けられている。【選択図】図２
