Abstract

Abstract A freight pallet may be formed in a wide variety of user determined configurations by assembly of a plurality of interlocking construction units. Each of the units has a square thin support plate with a projecting rib extending along a first pair of adjacent perpendicular side edges. A complementary formed groove extends along a second pair of adjacent perpendicular side edges of the support plate. A right angle corner support member is perpendicularly attached at each corner on a bottom surface of the support plate. Each pair of adjacent corner support members are connected by a support brace. The construction units may be assembled adhesively or through thermoplastic bonding by forming portions of the projecting ribs and complementary grooves from a thermosetting plastic material.
