ABSTRACT:
A billiard cue having a separate handle and shaft utilizes a quick operating connector to join the handle and shaft. The connector consists of male and female sections which are secured in the ends of the handle and shaft. The male section contains a cylindrical bar having an accurately machined diameter which snugly fits into a cylindrical cavity of the female section which is slightly oversized with respect to the male bar's diameter. The male bar and female cavity are axially aligned in the cue sections, and the bar engages the cavity over a linear distance sufficient to ensure accurate alignment of the handle and shaft when joined. Two flats at the end of the male bar provide a reduced diameter portion of the bar tip which fits between partial bulkheads within the female cavity, allowing insertion of the bar into the cavity. Upon a 90 degree rotation of the handle with respect to the shaft, the full diameter of the tip is captured behind the partial bulkheads and the two sections of the cue are mutually aligned and secured. In a second embodiment, when the male and female sections are mated, a compressible ring is in face to face contact with a flange on the male and a flange on the female sections of the connector. When a cue utilizing the connector strikes a billiard ball, the ring is compressed by the flanges and acts as a shock absorber for the impulse force transmitted through the cue.
