Patent ID: 7575264

Claim:
A cargo bed structure, comprising: a sub-floor assembly comprising a plurality of cross members in spaced relation; and a load-bearing deck overlying said sub-floor assembly and comprising a plurality of interlocking fiber reinforced polymer decking planks extending in a direction perpendicular to said cross members, said decking planks comprising: a first planar section having a load-bearing surface and an opposing surface and two opposed longitudinally extending edges; at least one support rib projecting from said opposing surface of said planar section, said support rib comprising a planar portion adapted for interfacing with said cross members; a first interlocking panel projecting from said opposing surface at one of said two opposed longitudinally extending edges of said planar section, said first interlocking panel comprising a longitudinally extending channel and a planar portion adapted for interfacing with said cross members; and a second interlocking panel projecting from said opposing surface at the other of said two opposed longitudinally extending edges of said planar section, said second interlocking panel comprising a longitudinally extending protrusion adapted for insertion into said longitudinally extending channel such that two adjacent decking planks are interlocked together and a planar portion adapted for interfacing with said cross members.
