ABSTRACT:
A foldable and self-erecting display stand has an easel mounted at the rear surface of a large planar board. The planar board and the easel are together foldable along a plurality of horizontal fold lines to a compact collapsed state. The easel has a U-shaped horizontal cross section and two mutually parallel triangular side walls. A plurality of pivotable cross braces extend in a canti-lever manner from a body board of the easel. A plurality of elastic cords are mounted between the cross braces and the side walls of the easel. The side walls of the easel are foldable to a collapsed position juxtaposed to the planar board against the elastic force of the elastic cords for folding the display stand to the collapsed state. The elastic cords are in a stretched condition when the display stand in the collapsed state, and the cross braces cooperate with the stretched elastic cords to self-erecting the display stand from the collapsed state to the erected state.
