Patent attributes
A billiard ball rack for racking 3 or more billiard balls is provided, comprising a base arm and two side arms configured to enable the billiard ball rack to be foldable and self-aligning. The inner surfaces of the base arms and the side arms are tapered at an angle relative to a top surface of the billiard ball rack, and the arms are pivotally connected to one another and configured such that when the billiard rack is positioned around a set of billiard balls and downward pressure is applied, the base arm and side arms of the billiard rack automatically adjust to form an equilateral triangle. The billiard ball rack is also configured to be folded compactly to fit within standard pool cue cases while the arms remain interconnected. Methods of using the billiard ball rack for racking billiard balls are also provided.
