发明名称 Pickup truck loading ramp
摘要 A folding ramp for attachment to the rear bumper and tailgate of a pickup truck. The ramp is formed by a pair of hingedly connected ramp panels of substantially equal overall dimension. One panel is slidably connected with the pickup truck tailgate in a manner to fold and unfold both panels from a loading to a stored position by vertical movement of the pickup tailgate. Legs support the ramp panels at their hinged position when loading and unloading wheeled vehicles, such as garden tractors, etc.
