ABSTRACT:
A folding loading ramp for attachment to the end gate of pickup trucks. The ramp is of such a construction so that it may fold up with the tailgate, take up minimal additional space, and not interfere with the normal use of the end gate of the truck. The ramp includes a number of foldable ramp members which are hinged to make a convenient ramp for hard to load items, such as garden tractors, motorcycles, snowmobiles, etc. Added support is given to the ramp by a supporting mechanism which folds within the ramp members when not in use. The supporting mechanism reinforces the ramp by virtue of its structure rather than by contact with the ground. This allows folding of the support mechanism within the ramp members for space saving and provides support when the loading ramp is used with a loading dock. A combination handle and locking mechanism allows for positioning the ramp as a space extension for the vehicle bed and pulling the ramp to an extended position from the folded position.
