There is provided a longitudinally collapsible canopy-like covering for longitudinally extending open-top frames, such as for the cargo-box of a pickup truck. The collapsible canopy structure comprises a plurality of substantially parallel arch-like ribs, each rib including a lofty spacer-member extending transversely across the frame member longitudinal axis and a pair of upright leg-members longitudinally movably associatable along the frame member; an elongate strip of flexible crease-resistant drapeable or festoonable sheet material cover is attached at relatively-long intervals to lower portions of the several ribs and is additionally removably attachable at relatively-short intervals with respect to the underlying frame member. Desireable refinements include: rigidly upright adjustable front-panel and rear-panel; a novel resinous internal construction for the sheet-like flexible cover; and transverse alignment means for the longitudinally movable rearmost-rib.
