Universal hitch mirror

Claim 1

A universal hitch mirror designed to be attached to a rear surface of a vehicle in order to allow a driver of said vehicle to view a trailer hitch, comprising: a base, being planar and triangular in shape, having an upper surface and a lower surface; means for securing said base to said rear surface of said vehicle; a mast, in the shape of an elongated cylinder, having an upper end and a lower end; a mast boss, integrally formed with said base and extending upward from said upper surface of said base, and having a boss mating surface; a mast pivot, integrally formed on said lower end of said mast, and having a pivot mating surface directly opposing said boss mating surface of said mast boss, wherein said pivot mating surface of said mast pivot and said opposing boss mating surface of said mast boss are each provided with a plurality of engagement teeth, so that said mast pivot cannot rotate relative to said mast boss when said pivot mating surface is drawn tightly against said opposing boss mating surface; wherein said boss mating surface of said mast boss opens into a base mounting hole passing completely through said mast boss; wherein said pivot mating surface of said mast pivot opens into a mast mounting hole passing completely through said mast pivot, with the central axis of said mast mounting hole being aligned with the central axis of said base mounting hole; wherein said pivot mating surface is drawn tightly against said opposing boss mating surface by the engagement of a base bolt and a base wingnut, with said base bolt having a threaded portion and a head portion, with said threaded portion of said base bolt being sized to pass through said base mounting hole and said mast mounting hole, and being sufficiently long to leave an exposed threaded portion of its length extending beyond said mast boss and said mast pivot, and with said head portion of said base bolt being sufficiently large to prevent its passage through said base mounting hole and said mast mounting hole, and with said base wingnut being threaded on to said exposed threaded portion of said base bolt, thereby drawing said pivot mating surface and said boss mating surface together; a mirror; and means for adjustably securing said mirror to said upper end of said mast; wherein said means for adjustably securing said mirror to said upper end of said mast comprises a mirror mount, fixedly attached to said mirror; an attachment ball, integrally formed with said mirror mount; a ball pocket, formed into the upper end of said mast, defined by a bifurcated side wall, and sized to receive said attachment all of said mirror mount; and means for clamping said bifurcated side wall against said attachment ball so as to frictionally hold said attachment ball in position in said ball pocket.
