Abstract: A folding table having a modesty panel employs a locking mechanism in the form of tab and hook assemblies to rigidify the table in the unfolded operative condition with the legs erect and the modesty panel in a position for use. The tab and hook assemblies are mounted on the panel and the tabs are received in slots in the adjacent leg assemblies to prevent hinged movement of the leg assemblies about their hinge axis. The hooks are rotatably and slidably supported in apertures in the tabs and are movable between a folded position and a leg embracing position. In the leg embracing position the hooks secure the tabs in the slots by preventing hinged movement of the panel.
