ABSTRACT:
A collapsible easel module adapted to support flip-chart pads or other material to be displayed, the module having a frame constituted by a front element adjustably coupled to a rear element to assume a caret-like formation. The front element is formed by upper and lower horizontal arms bridged by a pair of parallel legs at points of connection displaced from the ends of the arms. The rear element is formed by corresponding arms bridged by a single leg at points of connection at the midpoint of the arms. The complementary ends of the upper arms of the front and rear elements are joined together by double-barreled couplers which permit adjustment of the caret angle, the same couplers being adapted to accommodate the upper arms of the frame elements of a like module, whereby a series of modules may be joined together to create a free-standing display wall.
