Abstract: A transportable article support rack is disclosed. The transportable article support rack includes a hitch connector for releasable connecting the rack to a vehicle. The rack also includes a main column assembly pivotally mounted to the hitch connector, a support assembly for supporting an article, and a locking assembly adapted to lock the main column assembly in a transport position. The locking assembly includes at least first and second articulated locking arms, the articulated locking arms pivotally connected to one another. The second locking arm, when locked, forms a truss between the main column assembly and the support assembly for increased article support strength when in the transport position.
