发明名称 Telescoping truck loading ramp assembly
摘要 A ramp assembly facilitating the loading and unloading of a truck comprises two telescoping ramp sections including a forward section and a rearward section movable relative to each other between a full length ramp operating configuration and a stowed configuration. In one embodiment, the side rails of the rearward section of the ramp are slidably received within sleeve-like side rails of the forward section. In the stowed configuration of the ramp assembly, the ramp assembly is approximately half its fully extended length and fits between the existing longitudinal chassis frame members under the cargo deck of the truck without interfering with the housing of the truck differential. Accordingly, the invention makes possible the use of a full length ramp with virtually all truck sizes.
