Abstract
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.
