  • Patent number: 5881937
    Abstract: A vehicle cargo carrier, and specifically a movable frame assembly, for storing and transporting luggage, gear, equipment and the like on the exterior of a vehicle. The carrier is attached to a common trailer hitch and is particularly well suited for use with a mini-van or sport utility vehicle which has a rear opening door or hatch. The carrier is slidably movable, permitting outward extension, while still being connected to the vehicle, to provide easy access to and unobstructed opening of the vehicle rear door or hatch, and to provide unobstructed access to the vehicle's existing interior cargo area. Subsequently, the carrier is inwardly slidably retracted so that it is firmly disposed in an aerodynamically favorable position proximate the rear of the vehicle. The frame assembly comprises a connection member which interfaces with the hitch and a frame member which interfaces with the connection member. A storage box or container member is connected to the frame member.
