Patent ID: 7147566

Claim:
A cue sports training device adapted in use to be used with a cue sports table having a playing surface bounded by an edge and in use to support a plurality of balls which may rebound from the edge, the device comprising: (a) a light source adapted to emit a first and a second light beam across the playing surface, the light beams each having a principal axis; (b) an adjustment element adapted to jointly vary the angular displacement of the principal axes of the light beams about a common axis which is substantially perpendicular to the playing surface, wherein an intersection of the common axis with the playing surface is spaced inwardly from the edge by a distance substantially equal to the radius of the ball so as to define a position along the path at which the ball impacts the edge, in use the beams being positioned relative to the playing surface such that they would be incident with the balls supported on the table which may be located in their path; and (c) an adjustable spacer element, whereby the spacing of the common axis from the edge can be adjusted, wherein in use the device is positioned proximate to the edge of the cue sports table, and the angular displacement of the light beams can be adjusted by the adjustment element to define a desired path for a ball over the playing surface.
