Fold-up storage container

In a storage container having a base, the improvement comprising a skeletal frame for said base, said skeletal frame comprising pairs of interconnected parallel hollow channel members having closed upper surfaces and arranged in a rectangular grid, outer peripheral edges of each pair of said channel member being located at side of said base and having thereat a pair of spaced apart tubular fork openings adapted to insertably receive a pair of laterally spaced apart forks of a fork lift truck.

In a storage container having a rectangularly-shaped base and at least one corner of said base a first type connector body having through a front face parallel and adjacent to a first, short side of said base, an aperture through said face adapted to receive a first elongated fastener member disposed parallel to a second side of said base intersecting said first side thereof at said corner, the improvement comprising a second connector body identical to said first connector body but rotated ninety degrees in a plane parallel to said base and offset from said corner along said second side of said base, said second connector body having through an outer face thereof an aperture adapted to receive a second elongated fastener member disposed perpendicularly to said second side of said base, whereby a plurality of said containers may be interconnected via first and second connector bodies and first and second elongated fastener members in end-to-end and side-by-side configurations, respectively.

In a storage container having a roof panel and upright members connected at upper ends thereof at corners of said roof panel, the improvement comprising a raised L-shaped stacking block fastened to said roof panel, said stacking block having a generally flat upper surface and interior vertical side walls forming with intersecting sides of said roof panel a rectangularly-shaped space connecting with an upper end of said upright.

In a storage container having at least one pair of panels pivotably interconnected by a joint including first and second tubular hinge lug members having coaxially aligned bores axially rotatable with respect to one another on a hinge pin relatively rotatable with said bores, the improvement comprising a friction pin forced into said bores in interference fits therewithin to thereby immobilize said joint.
