  • Patent number: 4735454
    Abstract: A bifold loading ramp that is interchangeable with the tailgate of a pickup truck. A ramp consisting of two halves that are hinged in the middle with the upper half having existing tailgate latch assemblies welded to it, so as to allow it to attach to the bed of a pickup truck in the same manner as the tailgate. The latch assemblies hold the ramp in the vertical position when locked. When unlocked it pivots to a horizontal position being held in position by the existing tailgate support brackets making for a tailgate extension. When the tailgate support brackets are unhooked the ramp can then be unfolded forming a gradually inclined ramp from the ground to the bed of the truck.
