发明名称 Truck bed extender and telescoping ramp
摘要 A device providing a ramp into a truck bed, and extending a truck bed for the carrying of vehicles (such as ATVs) and items that are too long to carry with the truck tailgate raised. One embodiment is essentially a parallel pair of nested ramps, extenders and casings, each respective ramp telescopically and slidably received within a respective extender telescopically and slidably received within a respective casing. Lockpins inserted within holes aligned in the sidewalls of each casing and truckbed extender (and perhaps in each ramp), while they are in a desired configuration such as fully retracted (nested) or fully extended, prevent departure from that desired configuration.
