Abstract
The present invention relates to a novel adjustable billiard cue stick that is capable of being adjusted to multiple different lengths and configurations. In one embodiment, the pool cue stick includes a spring-loaded mechanism having a tension rod with fixed metal pegs. The metal pegs are locked into corresponding receiver holes for locking the pool cue stick into a desired length. A button releases pressure from a spring of the pool cue stick enabling the length of the cue to be adjusted. In another embodiment, the pool cue stick includes a segmented screw drive system in the center of the cue that can be manually or electrically cranked for adjusting the length of the pool cue stick.
Claims20
An adjustable pool cue comprising:
- a pool cue having a tip end, a forearm section, a plurality of telescoping shaft sections, a wrap section, a butt sleeve section, and a bumper end;
- wherein said forearm section, said wrap section, and said butt sleeve section are each of a fixed length;
- wherein each one of said plurality of telescoping shaft sections is independently extendable and retractable for varying a length of said pool cue;
- wherein each one of said plurality of telescoping shaft sections is extendable from about 1.5 inches in length to about 6.5 inches in length;
- and
- further wherein said pool cue is adjustable in length from about 43.5 inches to about 58.5 inches.
An adjustable pool cue comprising:
- a pool cue having a tip end, a plurality of telescoping shaft sections, and a bumper end;
- wherein said plurality of telescoping shaft sections includes at least two telescoping shaft sections;
- wherein said plurality of telescoping shaft sections is extendable and retractable for varying a length of said pool cue;
- a tension rod including a plurality of internal fixed pegs for fixing relative positions of an inner shaft to an outer shaft;
- said plurality of internal fixed pegs each selectively retainable in at least one receiving slot;
- wherein said tension rod is actuated with a button and a spring for biasing said tension rod and said fixed pegs;
- and
- further wherein said biasing said tension rod enables said fixing relative positions of said inner shaft to said outer shaft.
An adjustable billiard cue comprising:
- a billiard cue having a tip end, a plurality of telescoping shaft sections, and a bumper end;
- wherein said plurality of telescoping shaft sections includes at least two telescoping shaft sections;
- a centrally segmented screw drive for threading engagement with a central threaded shaft including a screw-nut interface;
- wherein a rotation of said centrally segmented screw drive in a first direction extends said threaded shaft and extends a length of said billiard cue;
- and
- further wherein a rotation of said centrally segmented screw drive in a second direction retracts said threaded shaft and retracts said length of said billiard cue.
