  • Patent number: 5678491
    Abstract: A plastic table structure includes a top having a planar upper surface portion, a lower plastic portion and a central wooden frame including a composite beam interposed between and enclosed by the top and lower portions.

Each leg assembly includes a pair of upper transverse supports that engage the leg-receiving channels of the lower plastic portion and extend across its entire width to provide a plurality of transverse load-bearing interfaces to enhance the rigidity and load-bearing capability of the plastic table.
