A knock-down utility trailer frame and suspension system characterized by an elongated hollow spine adapted to extend lengthwise of a trailer body, and a trailer hitch draw tongue carried within the spine and slideable longitudinally therein between extended and retracted positions. The hitch tongue is wedged in the extended position by cooperating compression pads on the tongue and in the encompassing spine which simultaneously capture a pair of wheel-mounting leaf springs on corresponding studs disposed within the trailer spine. As the tongue is moved to the retracted position, the tongue portion which captures the leaf springs move axially of the studs, whereupon the leaf springs and corresponding wheels may be disengaged from the trailer spine for storage.

A trailer frame and suspension system comprising a hollow spine adapted to extend lengthwise of a trailer body, a trailer draw tongue telescopically carried within said spine and slideable longitudinally therewithin between a tow position in which said tongue extends from said spine for coupling to a tow vehicle and a retracted storage position in which said tongue is withdrawn into said spine, means for suspending a ground-engaging trailer wheel from said spine and including a portion adapted to be located internally of said spine adjacent said draw tongue, and opposed clamping means carried by said tongue and said spine internally of said spine and having a releasing relationship with said portion of said wheel suspension means to condition said suspension for removal from said frame in the retracted position of said draw tongue and operable in the extended tow position of said draw tongue for rigidly clamping said portion within said spine and thereby mounting said wheel suspension means on said frame such that said wheel is cantilevered from within said spine.
