ADDITIONAL AUXILIARY EXPANSION MEMBER OF STEP-ON FACE AREA OF TRIPOD STEPLADDER
To provide an additional auxiliary expansion member of a step-on face area of a tripod stepladder that greatly expands a working range and greatly increases work efficiency, in view of the fact that the working range was limited when using the tripod stepladder.SOLUTION: An aluminum plate is prepared and bent according to the blueprints to produce an additional auxiliary expansion member of a step-on face area of a tripod stepladder. The additional auxiliary expansion member is inserted laterally through the space between main and auxiliary columns of the tripod stepladder currently commercially available, is set horizontally and fastened to the main column with a U-bolt.SELECTED DRAWING: Figure 4
【課題】三脚脚立使用時に、作業範囲に制限があった。作業範囲が大幅に広がり、作業効率が格段に上がる三脚脚立踏みしろ補助プラスを提供する。【解決手段】アルミ板を用意し、設計図に従って折り曲げて、三脚脚立踏みしろ補助プラスを製作する。三脚脚立踏みしろ補助プラスを、現在市販の三脚脚立の主柱と補助柱の空間部から横に差し込み、水平にセットし主柱にＵボルトで締めて固定する。【選択図】図４
