Abstract:
A billiards targeting disk for use with a billiards table having a supporting surface and at least one target, the billiard table including an object ball and a striking ball that rest on the supporting surface, the object ball having a central axis Co and radius Ro and the striking ball having a central axis Cs and radius Rs, said targeting disk comprising;a thin substrate having upper and lower surfaces and a perimeter, said upper and lower surfaces being planar and substantially parallel, said lower surface being adapted to lay flat on the supporting surface;an alignment pattern visible from said upper surface of said substrate, said alignment pattern having a border that defines an alignment origin Oa and a radius Ra corresponding to the radius Ro of the object ball, said alignment pattern providing a visual aid for aligning said alignment origin Oa under the central axis Co of the object ball;an alignment edge defining a first portion of said perimeter of said substrate, said alignment edge being proximal said alignment pattern;a targeting edge defining a second portion of said perimeter of said substrate; and,a targeting indicium visible from said upper surface of said substrate, said targeting indicium being located sufficiently close to said targeting edge to enable the striking ball to substantially simultaneously strike the object ball as it engages said targeting disk.
