Abstract
Abstract Apparatus and a method are disclosed for transporting a motor scooter or similar type vehicle on the back of a motor vehicle such as an automobile, van, pick-up truck or the like. The apparatus of the present invention attaches to the rear of the motor vehicle and includes a platform which, when not in use, is oriented in a vertical direction. When the apparatus is used to transport a motor scooter, the platform is lowered to the ground and the motor scooter can be loaded onto the platform. A restraining bar is used to secure the scooter to the platform. The platform, still with the horizontal orientation, is raised to prevent contact with the ground when the motor vehicle is in motion. To remove the motor scooter, the platform is lowered to the ground, the lowering of the platform causing the restraining bar to be released. The motor scooter can then be removed from the platform and the platform secured in a vertical orientation until required further. The platform is configured to permit motor scooters having different wheel configurations to be carried thereon.

Claim 3
Dependent Claim
30 words
The transporter unit of claim 1 wherein said platform includes structure permitting motor scooters to be loaded thereon from either side when said platform is positioned on the ground region.
Claim 4
Dependent Claim
22 words
The transporter unit of claim 2 wherein said platform has indentations for engaging wheels of a motor scooter positioned on said platform.
Claim 5
Dependent Claim
77 words
The transporter unit of claim 1 further comprising an attachment mechanism for coupling said frame unit to a motor vehicle hitch, said attachment mechanism including: a coupling member for insertion in the motor vehicle hitch and having an aperture for receiving a coupling pin; and a mounting member having a threaded aperture proximate said motor vehicle hitch when said frame unit is coupled thereto, wherein a set screw in said threaded aperture engages said motor vehicle hitch.
Claim 6
Independent Claim
185 words
A method of transporting a motor scooter on a motor vehicle, the method comprising the steps of: positioning a platform of a motor scooter transporter unit proximate a ground region for loading and unloading said motor scooter; when said transporter unit is to be placed in a stowed configuration, moving a lever normally in a first configuration to a second configuration; actuating a motor to raise said platform while said lever is in said second configuration, the combination of said lever in said second configuration and raising said platform causing said platform to rotate into a vertical position; when said transporter unit is to transport a motor scooter positioned on said platform, rotating an engagement arm into contact with said motor scooter and raising said platform, the combination of said engagement arm in contact with said motor scooter and raising said platform causing said engagement arm to apply a force on said motor scooter securing said motor scooter to said platform; and causing a clutch of said motor to slip when the force between said engagement arm and said motor scooter exceeds a predetermined value.
