ABSTRACT:
The present invention includes a telescoping ramp that includes two ramp members that fit one atop the other such that the two members may be extended out or collapsed together. The first, outer ramp member has channels on either side of a substantially planar surface. The channels of the outer ramp member are structured to capture the rails on either side of a second ramp member. An inverted J-shaped channel is formed along each of the longitudinally aligned sides of the first ramp member. One embodiment includes inverted J-shaped channels that are dimensionally larger near the side that engages the other ramp member. The second ramp member is sized to between the inverted J-shaped channels and includes protruding rail-like members formed along each of its longitudinally aligned sides. The protruding members are complementarily shaped to slide and fit within a corresponding inverted J-shaped channel of the first ramp member.
