ABSTRACT:
A folding scaffold for supporting workers and material including a folding frame and a plurality of supporting planks. The frame includes two ladder frames with rungs, which ladder frames are connected by the support frames which hold the ladder frames a spaced distance apart when the scaffold is fully extended. The support frames are of different size and they are hingedly connected to fit in the same plane when the scaffold is in the folded position. The larger support frame protrudes a spaced distance from the smaller support frame when in the same plane to form a handle for easy transport of the scaffold when folded. When fully extended the end of the larger support frame is equi-distant from the ladder frames. The supporting planks extend between the ladder frame and are notched to receive the rungs of the ladder frame to hold the ladder frames in a parallel relation. A removable snap-on spring clip retains the ladder frames in the folded position for transport or storage.
