Abstract
Abstract A portable collapsible lectern is featured that is easily transposed into an attache case. The lectern comprises an upright front panel having opposing vertical side walls perpendicularly joined thereto, and top and bottom panels horizontally disposed and perpendicularly fixed to the front panel and side walls. A pair of vertically disposed wing panels is pivotally joined along the respective vertical edge of the side walls for receiving and supporting a leaf panel therebetween. The leaf panel is pivotally joined along the horizontal edge of the top panel within the confines of the side walls, and is arranged so that it will extend from a closed position, wherein it is parallel to the front panel, to a deployed position, wherein it is outwardly extended about its pivotal axis to form a declining platform relative to the top panel. When the leaf panel is returned to its closed position, the wing panels are swung towards the center of the lectern and overlap the leaf panel in a parallel adjacent relationship thereto, thereby forming an enclosed attache case. Means are also provided for releasably securing the wing panels over the leaf panel when in its closed position.
