ABSTRACT:
An improved main joint and/or A joint for a billiard cue stick of the type having at least two detachable sections. The joints include mating tenons extending from opposing sections of the cue stick, and a threaded screw anchored in one of the two sections and extending axially outward through the respective tenon for screw insertion into the mating tenon of the second section. A single or dual-ring collar is also provided for encircling the mating tenons of the two sections. The collar encircles the tenons when the two sections are fully screwed together, and confines the tenons as the screw force causes them to expand. Both the A joint and main joint give an improved self-aligning compression fit. A billiard cue incorporating one or both of said joints will have an increased level of structural integrity in order to reduce deflection and resonance when the billiard cue strikes a cue ball. This helps to give the feel of a solid one-piece cue stick and increases the accuracy and life expectancy thereof.
