  • Method of making load-bearing structures
    Patent number: 5900203
    Abstract: In one aspect, the present invention provides a load-bearing structure with a novel interlocking edge. Also provided is a method of making a load-bearing structure having an overlapping edge, in which structural members are combined so that a stepped-down lip of one structural member covers a peripheral edge of another member. Also provided is a load-bearing structure having cellular structure and which is useful with or without an overlapping edge. In addition, there is provided a molding method for making cellular, load-bearing structures.
    Type: Grant

  • Molded structure
    Patent number: 5527585
    Abstract: A novel molded structure especially useful as a rigid, load-bearing structure, is provided. Also provided is a novel process for molding the structure, which may be in the form of a pallet. By the process, the structure is chilled as it is being formed. Recycled resins including contaminants of limited compatibility may be used.
