ABSTRACT:
A fold out display is particularly adapted to support a wide variety of different types of group work activities, team projects, and the like, and includes a free standing base which fixedly supports a primary panel having an exterior display surface. At least one foldable panel is hingedly supported on the primary panel for movement between a closed folded position overlying the primary panel, and an open unfolded position protruding outwardly coplanar with the primary panel. The foldable panel includes at least an interior display surface which overlies the display surface of the primary panel when in the closed folded position. A one-piece living hinge has opposite side portions connected with the side edges of the primary and foldable panels, and is shaped such that when the foldable panel is shifted into the open unfolded position, the two display surfaces are juxtaposed in a substantially contiguous relationship to collectively provide an enlarged generally continuous and uninterrupted display. A fold out header panel assembly may be provided above the primary panels, and a pair of telescoping outstops help retain the folding panels in their open unfolded position.
