Abstract: A clamp that locks two telescoping components such as a vehicle receiver hitch and a draw bar, for substantially reducing if not eliminating the "banging" or "rattling" between the two components. The clamp includes a standard sized U-bolt, whose throat rests in a seat formed by a receiver hitch collar and a receiver hitch tube. A bar has an arc-shaped cross-section and includes two holes adapted for receiving the threaded ends of the U-bolt. When the draw bar is inserted into the receiver hitch, the arc-shaped side of the bar is positioned within a seat formed by the receiver hitch collar and the draw bar. Standard locking style nuts are threaded onto the legs of the U-bolt and tightened, causing the arc-shaped side of the bar to be wedged against the receiver hitch collar and the draw bar, while wedging the U-bolt throat against the opposite side of the receiver hitch collar and the receiver hitch.

Abstract: A cargo and accessory carrier for attachment to a vehicle receiver hitch includes a riser assembly secured to the vehicle, a door assembly pivotally secured to the riser assembly, and a platform assembly pivotally secured to the door assembly for carrying cargo at a desirable elevation above ground level, such that the door assembly can be pivotally rotated in a horizontal plane and a parallel plane while secured to the riser assembly. The platform assembly can be rotated about the door assembly and maintained in a vertical or horizontal position relative to ground, whether or not it carries a load or it is installed on the vehicle. The carrier provides a multipurpose support assembly which can be used as a "stand alone" unit to carry cargo, and which can be used in combination with other accessory carriers such as a cargo chest, bicycle carrier, ski carrier or any number of other accessory-carrying devices.
