PROBLEM TO BE SOLVED: To prevent a ladder from coming into contact with an eaves gutter when the ladder is placed against a roof, reduce a load of an ascending/descending person by half by receiving the load by a roof surface, and concurrently stabilize the ladder by preventing side slipping.SOLUTION: Auxiliary metal fittings 3 are fixed to both side posts of a ladder by a U-bolt 4 and a thumbscrew 5 in parallel with an upper step of the existing ladder 1. Angle stoppers 12 and feet 10 with antislip rubber, which are attached to tips of both side arms 7 and 8 of the auxiliary metal fittings 3, are directly installed on a roof surface.
【課題】屋根に梯子を立て掛ける時、梯子が軒樋にふれないようにし、且つ登り降りする人の荷重を屋根面で受けて半減させ、同時に横滑りを防ぎ安定を図る。【解決手段】 既存の梯子１上部の段と平行になるように補助金具３を梯子の両脇柱にＵボルト４と蝶ネジ５で固定して、屋根面に直に３の両側アーム７と８の先端に取り付けた角度ストッパー１２及び防滑ゴム付き足１０を設置させる。【選択図】図１
