Modular pallet arrangement

Claim 1

A modular pallet arrangement formed of a plurality of molded plastic units adapted to be interconnected in interlocking relation to form one complete pallet that, when heavily loaded and stacked with similar pallets, is capable of being supported only by laterally spaced warehouse rack rails, comprising: (a) an upper section including a plurality of generally similar upper units, each comprising a rectangular, grid-like, base member having, at each corner thereof, four separate, integral, downwardly extending, upper connector elements; (b) a lower section including a plurality of elongated lower units each comprising a flat, rectangular, grid-like base member having, at each end thereof and intermediate the ends thereof, quadruple compartmented, integral, upwardly extending, end and center connector elements, respectively; (c) certain compartments of certain of said lower unit connector elements being arranged and disposed for telescoping relation with corresponding upper connector elements of at least two adjacent, but separate, upper units to connect said adjacent upper units to each other, whereby said upper pallet section is supported on and by said lower pallet section; (d) said lower section including elongated, rigid, reinforcing members extending laterally between corresponding connector elements of lower units to prevent said pallet from sagging in the center.
