Abstract
A modular hitch mount connection for attaching a tubular carrier structure to a load arm that is inserted in the receiving tube of a receiving type hitch. A tubular seat is provided that has an open end for slidably receiving the support tube in an open end of the seat. Correct positioning of the support tube in the tubular seat produces alignment of holes in walls of the tubular seat with orifices in sidewalls of the support tube. A tensioning bolt inserted through a hole in the seat wall and a corresponding orifice in the sidewall of the support tube screwably engages a threaded nut located inside the support tube to secure the support tube to the tubular seat and in the process reduce play and wobble between them. Further play and wobble may be eliminated from the modular hitch mount connection by further inserting a connecting bolt through a hole in another wall of the tubular seat and a corresponding orifice in the second sidewall. Similarly, a receiving nut is provided on the interior surface of the support tube, but a central axis of the second nut is oriented at 90° to that of the first nut because it is on an adjacent wall of the support tube. This cross-orientation of the bolts cooperates to secure the support tube to the tubular seat. The tensioning bolt and the connecting bolt together restrict movement of the support tube by causing solid contact between the walls of the tubular seat and the sidewalls of the support tube.
