ABSTRACT:
A telescopic tailgate ramp (10) has a base tray (20) and a series of telescopically-connected trays (40, 60, 80) that are slidable with respect to one another and are stackable to replace a tailgate of a vehicle. Each tray (20, 40, 60, 80) is a plate with end pieces on each side that engage the end pieces of a preceding or succeeding tray. The end pieces have a channel and a tenon-like portion that engage a corresponding tenon or channel portion of a preceding or succeeding tray. Each plate has a corrugated surface (102) for enhancing traction. The trays (20, 40, 60, 80) are prevented from being fully withdrawn from one another due to the placement of pins in corresponding channels and tenons that engage each other. The trays (40, 60, 80) succeeding the base tray are prevented from sliding past the rear portion of a preceding tray or the rear portion of the base tray (20) securing an obstruction over the rear portion of each channel. The base tray (20) holds the other trays and is pivotable within the tailgate frame (12) of a vehicle (11) upon which it is mounted. The base tray (20) is also pivotable about an axis through points on support bars (104, 110) that are attached to the base tray (20). Handles (100) facilitate movement and manipulation of the ramp (10) in general and the individual tray sections (20, 40, 60, 80).
