A Collapsible Trailer. The trailer is lightweight, but durable, and includes a set of detachable deck segments that can be assembled into a deck. The trailer further includes a suspension assembly that attaches to the deck once the deck is assembled or, alternatively, is permanently attached to one deck segment. Intra-deck segment support is provided by slidable rods that are extendable to bridge between a pair of adjacent segments. Each deck segment has a male edge to be inserted into a female edge to create an exceedingly strong, interlocking hinge-like structure. The deck and trailer can be assembled without the need for any tools. The deck segments, when disassembled, are stackable into a condensed deck stack. A foldable suspension facilitates the stackable storage and transportation of the trailer. The trailer is convertible into a cargo platform that can be attached directly to a conventional trailer hitch receiver on a vehicle.

1. A collapsible trailer, comprising: a deck comprising three interlocked deck segments, each said deck segment comprising opposing interlocking edges, each said interlocking edge defined by alternating male and female edge portions, said female and male interlocking edge portions cooperating to be interlockable one with another of an adjacent segment; a suspension assembly attached to a bottom side of one said deck segment; and a hitch strut extending forward from said deck; said trailer further comprising a head segment defined by a male receiver socket at its leading edge and said alternating male and female interlocking edge portions at an opposing trailing edge, said male receiver socket defined by a bore formed therein. 2. The trailer of claim 1, wherein said deck comprises three interlocked segment assemblies, each said assembly comprising one said deck segment and a pair of slidable rods slidingly engaging a pair of rod bores formed in said deck segments. 3. The trailer of claim 2, wherein each said deck segment comprises opposing side edges, one said rod bore is formed to run longitudinally along each said opposing side edge. 4. The trailer of claim 3, wherein each said rod bore defines a leading end and a trailing end, said side edges further being defined by a slot formed therein to reach said rod bore at both said leading end and said trailing end. 5. The trailer of claim 4, wherein said leading end slot terminates in a handle pocket formed therein. 6. The trailer of claim 5, wherein each said slidable rod further comprises an actuating handle extending therefrom, said handle pockets formed in said side edges of said segments cooperatively configured to accept said actuating handles therein. 7. The trailer of claim 6, further comprising a lighting adapter attached a trailing edge of one said deck segment or said head segment, said lighting adapter further comprising trailer lamps displayed therefrom. 8. The trailer of claim 7, wherein said bore of said male receiver socket is configured to accept a hitch strut therein. 9. The trailer of claim 8, wherein each said female edge portion defines a cross-section having a generally circular central bore void. 10. The trailer of claim 9, wherein each said male edge portion defines a cross-section having a protruding knuckle appendage. 11. The trailer of claim 10, wherein said protruding knuckle appendage defines an axis that is aligned transverse to said longitudinal bore. 12. The trailer of claim 11, wherein said central bore void is accessed through a mouth, said mouth defining a gap, said gap being equal to or slightly greater than a distance between opposing faces of said protruding knuckle appendage. 13. A horizontal load-bearing structure, comprising: a plurality of interlocked deck segment elements, each said deck segment element comprising: a flat shape defining a front edge, a rear edge opposing said front edge, said front and rear edges both comprising alternating male and female interlocking edge portions, said deck segment elements further defined by a pair of opposing side edges perpendicular to said front and rear edges; whereby said front and rear edges are cooperatively configured such that said male edge portions insert into said female edge portions to form an interlocked hinge between a pair of said interlocked deck segment elements, said structure further comprising a head segment defined by a male receiver socket at its leading edge and said alternating male and female interlocking edge portions at an opposing trailing edge, said male receiver socket defined by a bore formed therein. 14. The structure of claim 13, wherein each said side edge comprises a longitudinal bore formed therein along said edge, each said deck segment element further comprising an elongate rod slidably inserted into said longitudinal bore and extending substantially from said rear edge to said front edge. 15. The structure of claim 14, wherein each said deck segment element defines a top surface in spaced parallel relation with a bottom surface, said top and bottom surfaces defining a horizontal deck plane, said flat transverse surfaces lying in the same horizontal plane as said top and bottom surfaces in a transverse direction, and lying in a different plane than said horizontal plane in a longitudinal direction. 16. The structure of claim 14, wherein each said female edge portion is defined by a transverse void across substantially its entire width, said transverse void accessible through a mouth formed by said female edge portion, one said male edge portion insertible into said transverse void through said mouth. 17. The structure of claim 16 further comprising a pair of suspension assemblies extending from said bottom surface of at least one said deck segment, each said suspension assembly comprising a pivoting frame pivoting around a pivot axis from an in-use position to a stowed position. 18. The structure of claim 17, wherein each said suspension assembly comprises a dampening element compressed between said pivoting frame and said deck segment to which said suspension assemblies are attached when each said assembly is in said in-use position.
