Abstract: A vehicle axle carrier having a one piece aluminum body produced by a low pressure die casting process and which integrates each of a differential housing, axle tubes, and attachment points for each of wheels/hubs, suspension struts, control links, jounce bumpers and electrical harnessing or brake line connections. Localized areas of the body, including the axle tubes exhibit varying thicknesses in order to compensate for the mechanical properties of aluminum. The low pressure die casting process accounts for each of die pull direction, draft angles and minimal wall thicknesses, with the aluminum body produced combining the features of lighter weight and infinite recyclability.

Abstract: A spreader bar for use in connection with a harness worn by a sailboarder. The spreader bar is fixedly interconnected with the harness and includes a sheave adapted to engage a line affixed at its ends to one arm of the wishbone boom of a sailboard. The spreader bar allows the user to support his weight on the boom line with the sheave adapted to roll on the line in response to movement of the board sailor or the boom. The sheave is supported so as to be easily engaged and disengaged from the boom line.
