1. An articulably collapsible cart assembly having a lower frame, the cart assembly enabled to carry a load in an open orientation, and to be collapsed into a minimal tri-folded configuration without a load, the cart assembly comprising: a lower frame first end having a pair of free-wheeling support wheels in a spaced apart manner on an axle; a lower frame second end connected to the first end by an elongated connecting frame, the second end having a pair of wheels thereon, and wherein the elongated connecting frame has a mid-frame lower collapse axis thereon which permits the first end of the elongated frame to be folded very compactly under the lower frame second end; an upper frame arrangement connected to the lower frame, the upper frame arrangement having an uppermost collapse axis thereacross and an intermediate, transversely disposed, cart-assembly-carry, collapse axis thereacross, wherein the intermediate axis comprises a carry handle, the uppermost collapse axis and the intermediate collapse axis enabling the uppermost frame arrangement to be pivoted counter to one another towards the lower frame, to collapse the cart assembly into a hand-carryable configuration by the intermediate, cart-assembly-carry collapse axis handle.
