  • Patent number: 6767025
    Abstract: A two-wheeled trailer which can transported, when empty, in a folded position with its wheels off of the ground. Particularly useful for hunters who want to get into the back country without having to pull a trailer, it can be rapidly deployed when needed to haul game. The folding trailer is also handy for do-it-yourselfers who want to move lumber, plants, fertilizer, and the like. The trailer includes a rectangular frame which is mounted on a pair of wheels and a “T”-shaped member. Hinged to a transverse cross brace which generally bisects the rectangular frame are two arms. Disposed perpendicularly to the transverse cross brace, the arms terminate forwardly proximate with the distal ends of the “T”-shaped member to which they are pivotally connected. When the trailer is unfolded, the leg of the “T”-shaped member extends in front of the wheeled frame so as to define a tongue.
