Abstract: A side window shade for automobiles is formed from a panel having a plurality of sections connected by double folding joints. An upper edge of the panel is configured with a curvature corresponding to an automobile side window frame and includes a plurality of spaced notches which removably receives suction cup retainers for securing the panel to an automobile side window. The panel may be formed from a white corrugated cardboard material or may be at least partially formed from a tinted transparent material to allow visibility through the side window. The suction cup retainers each include a pair of pivotally connected jaw members and a spring which biases the jaw members to a closed position. Aligned clamping portions of the jaw members are each provided with a friction enhancing pad for engagement with the panel.

Abstract: The scaffold system of this invention includes structures for retaining hollow folded metal planks on scaffold end frames or scaffold side brackets. A plank retaining lug is used to engage the underside of a plank and cooperates with a hold-down shoulder to retain the plank in place. A frame header may use the structures described to retain planks on both sides of an end frame. The frame header may be releasably mounted to a conventional scaffold end frame. Side brackets may be equipped with the structures to retain planks cantilevered from the scaffolding system.
