Claim:
A ramp having an upper surface and a lower surface, the ramp comprising: a main section, comprising, an upper section having a hinged end and a distal end, a lower section having a hinged end and a distal end, and a hinge connecting the hinged end of the upper section to the hinged end of the lower section, the hinge constructed such that the upper and lower sections can be folded together in a substantially parallel configuration, with the lower surfaces of the upper and lower sections facing one another, and the upper and lower sections cannot be folded together such that the upper surfaces of the upper and lower sections form less than a one hundred and eighty degree angle, and a landing section, comprising, a riser section having a first end and a second end, a first hinge connecting the first end of the riser section to the distal end of the upper section, the first hinge constructed such that the riser and upper sections can be folded together in a substantially parallel configuration, with the lower surfaces of the upper and riser sections facing one another, a landing platform having a first end and a second end, and gripping structures depending from the lower surface of the landing platform, and a second hinge connecting the second end of the riser section to the first end of the landing platform, the second hinge constructed such that the riser and landing platforms can be folded together in a substantially parallel configuration, with the lower surfaces of the retaining and riser sections facing one another, the second hinge having a lock to retain the retaining and riser sections in a desired angular position.
