Application No. 09/692,431
telescopingly received within the second support base upper end portion 34, in a
manner as described relative to the legs 22, 23, and 24 of the first guide assembly 11.
Upon mounting of the first and second guide assemblies to the respective trailer
ball "B" and the trailer tongue "T", as illustrated in Figure 7, an individual peering
rearwardly from an associated tow vehicle may ascertain the proper positioning of the
telescoping leg portions of each guide assembly to effect abutment of the guide
assemblies relative to one another and thereby the alignment of the trailer tongue to the
trailer ball.
The appellant argues (brief, pp. 7-8) that Law fails to teach (1) a series of
spacing indicia along the upper shaft of the upper telescoping mast, (2) a series of
spacing indicia along the upper shaft of the second upper telescoping mast, (3) a hitch
base comprised of a sturdy magnetic disc with a first mast receiving cavity formed
therein being tapped and being female-threaded for threadingly mating with the lower
base mast allowing for a screw-type connection, (4) a ball base comprised of an
annular magnetic ring and a second mast receiving cavity formed within the protrusion
thereof at an offset from a center of the magnetic ring, and (5) a lower ball receiving
bevel formed along the lower surface of the ring, thereby widening the outer diameter of
the lower portion of the central orifice.
