  • Patent number: 8075415
    Abstract: A cue stick handle includes: an exterior casing of conical members; a rigid inner core, which includes linearly interlocked and glued components, including (a) a rigid tube composed of a hard, tensile material that provides steel-like characteristics, including rigidity and stiffness and (b) a pin holder composed of a strong composite or plastic material, having a high tensile and high bending strength, and adhesively coupled to the tube. The first end of a joint pin is securely inserted within the pin holder and a second end of the joint pin extends in an axial direction away from the tube. The tube is filled with a vibration-dampening, foam-like material. The rigid inner core may include a wood core securely mated to an end of the rigid tube. A pair of collars is coupled to each end of the rigid inner core to secure the rigid inner core inside the exterior casing.

  • Patent number: 6881153
    Abstract: The present invention relates to a tip section for a cue stick for use in billiards, snooker and pool. The tip section may be connected to either a butt section of a two piece cue, or to the shortened shaft end of an existing cue stick butt section. The tip section is composed of a hollow tube into which stiffening members and weights may be introduced to alter the weight, balance, flex and kick of the tip section. The tip section can be retrofitted to an existing butt section, used to repair a cue stick with a damaged tip segment, or be part of a new cue.

  • Patent number: 6132321
    Abstract: A joint system for cue sticks. The system includes a joining member, a sleeve, and a receiving member. The cue stick shaft is prepared by drilling and tapping therein a centered threaded bore extending inwardly along a longitudinal axis from a center end face which is transverse to the longitudinal axis. The cue stick handle is similarly prepared. The joining member is preferably integrally formed or machined from a single solid part, and includes a pin portion and a smaller stud portion with a transverse oriented transition portion therebetween preferably shaped as an annular face portion. The pin portion has an externally threaded engagement portion adapted to securely locate the joining member, in the threaded bore in the cue stick shaft. The stud portion extends along the longitudinal axis outward from the pin portion, and has, at the distal end, a threaded locking portion. A receiving member is provided to receive the stud portion.

  • Patent number: 5290030
    Abstract: A cue having a hollow cylindrical handle and a hollow cylindrical shaft with a constant external diameter. A tip member fixed to one end of the shaft and a connector fixed to the other end of the shaft. A butt member fixed to one end of the handle and a connecting member fixed to the other end of the shaft to connect the handle to the shaft. An adjustable weight is located in the hollow handle and a bridge sleeve surrounds the shaft. The bridge sleeve has a bushing at each end with an inner diameter slightly greater than the outer diameter of the shaft so that the shaft can slide through the bridge sleeve to cause a steady movement of the cue.
