US Patent 9144731 Sliding plastic sleeve for pool cue

A friction-reducing sleeve that may be easily installed on a pool cue to provide the user with a comfortable ergonomic grip while providing low static and dynamic coefficients of friction preferably comprises an open ended, generally tubular seamless sleeve that may be fabricated with one or more layers of woven, natural and/or synthetic, material. The cue sleeve is preferably generally cylindrical, but capable of radial self-adjustment, to maintain a conforming fit that results in constant contact between the inner surface of the sleeve and the tapered outer surface of the cue. The sleeve outer surface is characterized as having a high static coefficient of friction to ensure a slip-free grip.
