A quick release mechanism for a sign stand base having support legs pivotally joined to a support flange. The support legs are notched to receive the support flange. A locking pin extends through the support leg and is positioned so s to selectively interfere with an outer periphery of the support flange. The locking pin is mounted for rocking or swiveling motion within the support leg and can be moved out of contact with the support flange, thereby allowing the support leg to pivot with respect to the support flange. A flat spring strip secured to an outer surface of the support leg biases the locking pin to a position engaging the support flange.

[ What is claimed is:] [1.]1. A foldable supporting device comprising:a base member including a plurality of support flanges having respective outer peripheries;a plurality of legs pivotally mounted to respective support flanges for pivotal movement between operational and storage positions;said legs defining a slot for receiving portions of a respective support flange outer periphery as the leg is pivoted between unfolded and folded positions;the outer peripheries of the support flanges defining at least one locking recess;a plurality of locking pins extending through respective legs, the locking pins having an elongated double-ended body with an enlarged head at one end lying outside the leg and an exposed portion at the other end extending beyond the leg;the locking pins carried by the legs so as to be positioned adjacent the support flange outer periphery and so as to be movable between a locked position received in the locking recess and an unlocked position outside of the locking recess;a plurality of spring bias means carried on respective legs so as to urge the locking pin body into the recess to lock the leg against pivoting about the support flange;the locking pin movable out of the recess when the exposed portion is deflected so as to oppose the force of the spring bias means;the spring bias means comprises a spring strip of flat spring material having first and second ends; andthe first end of the spring strip being fastened to the leg at the point of pivotal mounting to the support flange.
