Abstract:
1. A billiard ball rack for positioning billiard balls, comprising: a support structure having two side members and a rear member that together form a billiard ball-receiving space that is generally triangular in plan view, the two side members and rear member disposed at about sixty degrees relative to one another, the support structure including a front portion and a rear portion, the front portion having first and second inner surface portions facing the billiard ball-receiving space and having a shape that, in use, positions at least five standard billiard balls having a diameter of about two and one quarter inch diameter in a packed planar configuration wherein each billiard ball contacts at least two adjacent billiard balls; a movable push assembly movably mounted to the support structure, wherein the push assembly is movable forward from a retracted position towards the front portion of the support structure, the push assembly having a first push surface facing the billiard ball-receiving space, the push surface having at least five contact areas shaped to simultaneously contact a row of five standard billiard balls of a group of fifteen billiard balls positioned in the billiard ball receiving space when the push assembly is positioned forward of the retracted position; the push assembly further including a second push surface that is movable relative to the first push surface from a use position to a non-use position, the second push surface having at least four contact areas shaped to simultaneously contact a row of four standard billiard balls of a group of ten billiard balls positioned in the billiard ball-receiving space when the second push surface is in the use position and the push assembly is positioned forward of the retracted position.
