ABSTRACT:
A skeletonized, adjustable, high-rise scaffold assembly employs stacked sections, each made-up of a pair of opposed end frames or panels. The end frames of cooperating upper and lower sections are each provided with a pair of main or outer, supporting side legs and retained latching pin means for vertically adjustably connecting the sections together. Side legs of each end frame have a pin connector extending inwardly within a plane of the frame to removably receive ends of cross brace members that are mounted to extend from an end frame of one section diagonally across in a connected relation with an opposed end frame of the other section. The cross brace members have spaced-apart latching hole portions at at least one of their ends to enable a selection of a proper hole portion that is related to or compatible with an up or down adjustment of the frames of an upper section with respect to frames of a cooperating lower section. In one embodiment, the section bracing connections are made between inner or secondary leg members of the opposed frames, and in another embodiment, the connections are between main or outer leg members of the opposed frames.
