ABSTRACT:
A lightweight knockdown table and cabinet structure adapted for ease of assembly and disassembly comprised of a plurality of hollow tubular frame members releasably interconnected by a plurality of fasteners and lock assemblies and having a multi-sectioned top which adds rigidity and support to the structure. The fastener and lock assemblies each include a fastening device with multiple end connectors. The fastening devices are slidably insertable into the frame members and have a guide slot bridging into a locking slot. The end connectors are also insertable into the frame members and have a projecting male connector end. The male connector end is insertable into the guide slot and movable into locking engagement within the locking slot to releasably interlock the frame members together at right angles. The multi-sectioned top includes adjacent middle and side sections with support flanges which rest upon opposing frame members. The side sections each have an outwardly extending re-enforcement lip which lies under the adjacent frame member to add rigidity and support to the structure.
