A collapsible portable framework is expanded to an open position forming a long, narrow, column-like structure for a folding display frame, in which generally rectangular frame-like cubicles are aligned serially and are pivotally joined at common ends of the cubicles. Each cubicle has hubs at its corners pivotally joined to ends of rigid rods interconnected at pivot points forming a pair of scissor members along opposite sides of each cubicle. End braces releasably interlock as a rigid box frame to support the ends of the scissor members and the hubs at the corners of the cubicles in rigid spaced-apart positions. A diagonal cross-brace extends from a lower front corner to an upper rear corner of each cubicle, and another diagonal cross-brace extends from an upper front corner to a rear lower corner of each cubicle. Disconnection of the end brace members permits the frame to be collapsed by folding the scissor members so the cubicles are collapsed into a compact side-by-side form. Preferred end support members comprise a pair of rigid U-frames affixed to corresponding hubs at the ends of the cubicle so that base portions of each U are movable adjacent to one another. A pin and socket affixed to the base portions of the adjacent U-frames are interlocked to hold the U-frames in a rigid supporting position at each end of the cubicles and are released to pivot the U-frame away from one another during folding of the scissor members to the compact form of the frame structure. |
