发明名称 Method and apparatus for positioning a billiard game rack
摘要 Apparatus for cooperation with an associated billiard table which includes first and second laser apparatus for producing respective first and second laser spots, a rack for positioning a plurality of balls confined within said rack. The rack has first and second indicia thereon and a support carrying said first and second laser apparatus in spaced relationship. The support may be dimensioned and configured to permit adjustment thereof to align respectively said first and second laser spots with respectively said first and second indicia when said rack is in a predetermined location on the associated billiard table. Some forms of the apparatus include at least one ball and socket joint for supporting at least one of the first and second laser apparatus. Other forms of the apparatus include a support that includes first and second socket joints for respectively supporting said first and second laser apparatus. The rack may be triangular and the first and second indicia may be positioned on first and second sides of the rack and said first and second sides of the rack may be adjacent. In some forms of the invention first and second sides of the rack intersect in a first apex that is proximate to the apex ball when the balls are racked. The first and second indicia may be disposed at equal distances from an apex. Various forms of the method include the step of providing adjustable structure that includes providing at least one ball and socket joint. Other forms include the step of providing a rack includes providing a rack that that is triangular and has first and second indicia on first and second sides of the rack and said first and second sides of said rack are adjacent. The method may include a step of providing a rack that has first and second sides of the rack that intersect in a first apex that is proximate to the apex ball when balls are racked within the rack. The method may include the step of providing a rack that has the first and second indicia disposed at equal distances from the first apex.
