Billiard/pool cue |
摘要 |
A ferrule mounted on one end of a billiard/pool cue shaft has greater compressibility than the compressibility of the shaft to compress on impact of a tip mounted on the ferrule with a ball to absorb a portion of impact forces and to provide easy outward flexure with minimal buckling of the end of the shaft during impact. A bore extends a predetermined distance from the one end of the shaft toward a butt end of the shaft. The bore in the shaft communicates with a bore in the ferrule when the ferrule is mounted on the shaft. The ferrule is mounted on the shaft by means of a tenon formed on one end of the shaft or on the ferrule, which tenon tightly engages the other of the ferrule or shaft. The tip has a smaller than conventional radius to centralize impact forces toward the line of stroke extending along the longitudinal axis of the shaft.
