ABSTRACT:
A stepladder foot-platform comprising a large flat panel, designed to extend through the plane of the stepladder rungs, on this side as well as beyond this plane, between the frame studs, and to come to flatly abut against the top face of an intermediate rung or step. An anchoring foot is provided to frictionally, releasably, fixedly secure the panel about a horizontal plane in an operative, upright, stepladder position, this foot being secured to a lower step. Sliders also act upon the panel to prevent sliding motion of the panel in its horizontal plane, by fixedly securing same frictionally, releasably to the step onto which it rests. The footplate is characterized in that it enables a person to use it by placing his feet on the panel inwardly as well as outwardly from the ladder plane, in total safety, and in that it clears the stepladder so as not to constitute an obstruction to the free travel of that person ascending or descending that rungs.
