Abstract: A panel structure comprises a frame members defining the perimeter of the panel structure. The frame members have a first side facing outwardly of the panel structure and an opposed side facing inwardly. A panel member extends between the frame members and is engagable therewith. The panel member comprises an inner honeycomb core constructed from cellulosic material and having a pair of opposed side faces and a pair of opposed side panel members having a first side facing outwardly of the panel structure and an opposed side facing inwardly. Each of the opposed side faces is affixed to a respective side of the honeycomb core. The side panels are constructed essentially from material which, when not affixed to the honeycomb core, is non-structural and, when affixed to the honeycomb core, has a tensile strength sufficient to prevent compressive movement of the opposed side of the honey comb core.

Abstract: A panel structure, as used for space dividers and other purposes, has an identical frame member at each side. Each frame member comprises an extrusion of the same cross-sectional shape, having on one side surface at least one formation comprising a projection and a recess disposed symmetrically about a median plane which extends longitudinally of the extrusion. The frame members extend vertically at each end of a central portion of the panel with their respective side surfaces facing outwardly. Two adjacent panels are held together by bringing the endmost frame members of the respective panels into contact so that the formations on the respective members interfit. Locking members are then snapped into slots in the respective frame members.
