ABSTRACT:
A stowable loading ramp assembly for small vehicles, such as pickup trucks, vans and trailers, which includes a stowing chamber and an extendable loading ramp. The assembly is installable in a truck bed, or the like, with the stowed loading ramp access positioned toward the rear or tail gate of the vehicle. The loading ramp is locked in the stowed position by a floating locking plate, which is raised to permit the loading ramp to be withdrawn from the stowing chamber. The floating locking plate rides on a wheel on the top surface of the loading ramp until the ramp is fully withdrawn and, at that point, the wheel drops from the top surface loading ramp, locking the ramp in position. The floating locking plate also serves as a transition surface between the loading ramp and the top surface of the stowing chamber. Additionally, the loading ramp has attached thereto support legs, which provide support during the loading operation and, table legs which position the ramp at a height to be used as a table.
