Abstract
A ramp attached to and used for the loading and unloading of goods from a vehicle, typically a truck. When not in use, the ramp folds compactly and is latched in an upright position at the rear of the vehicle. The ramp may be unfolded and extended in order to transport goods to and from the vehicle. As used, the ramp also may be latched in a half-ramp arrangement to serve as a bridge or dock plate. In the half-ramp arrangement, the ramp is folded to form two legs of a three-dimensional triangular structure, so that one portion of the ramp supports the other and allows it to bear weight.
