Abstract (en)
Light-weight collapsible support structures in the nature of easels, book rests and the like which are self sustaining in a predetermined fully erected configuration, comprise in the fully erected configuration a multiplicity of forwardly facing panels (10, 12, 14) upstanding in a rearwardly inclined or substantially vertical postion to provide support surfaces for the displaying, supporting or anchoring of articles such as pads, books or the like. Forwardly extending ledge portions (16, 18, 20) from the bottom edges of such support surfaces, said ledges serving to rigidify and stabilize the erect configuration of these structures against collapse, but so adapted as to be foldable into a position allowing for such structures to be compactly folded up and collapsed for storage or for carrying when not in use. Behind the support surfaces, a plurality of panels (42, 44, 46) secures the various panels of the support structure against relative displacement.
