  • Patent number: 6447237
    Abstract: A pivoting bed trailer to be towed behind a motor vehicle for transporting a wheeled vehicle includes a main frame having a trailer hitch at a front end for coupling with the motor vehicle and a rearward end that engages the ground in an inclined loading condition and supported horizontally above the ground in a transporting condition. The main frame includes longitudinally extending guide rails for laterally aligning the vehicle. A pivot frame frontally and laterally bounds the main frame and the guide rails and is connected to said main frame at a transverse pivotal connection. The pivot frame includes pair of laterally spaced wheel assemblies carried by leaf spring below the pivot frame forward of the pivotal connection whereby rotation of the pivot frame about the wheels raises and lowers the transverse pivotal connection and moves the main frame between the loading condition and the transporting condition.
