Abstract
A cue for billiard sports that has a butt section, a joint collar, and a shaft section that has a kinetic energy absorbing insert located in the shaft section of the cue. A shaft section that has a kinetic energy absorbing insert that may be connected to an existing joint collar and butt section of a cue to improve the kinetic energy absorbing characteristics of the cue. A kinetic energy absorbing insert that is to be received by an existing shaft section of a cue in order to increase the kinetic energy absorbing characteristics of the cue is also disclosed.
Claims42
A cue having a butt section, a joint collar, and a shaft section having a tapered cylindrical shape with a first end and second end, the shaft section comprising:
- a shaft having a longitudinal bore extending into the shaft, the bore defining a bore diameter;
- a tip portion having a ferrule and a tip, the ferrule being located at the first end of the shaft, the tip being removably connected to the ferrule;
- a joint insert located at the second end of the shaft for connecting the shaft section to the joint collar and to the butt section;
- and
- a kinetic energy absorbing insert located in the bore of the shaft and contacting the shaft.
A shaft section for a cue used for billiards games comprising:
- a shaft having a first end and a second end, wherein the shaft section tapers outwardly from the first end to the second end, and a bore extending into the shaft, the bore defining a bore diameter;
- a tip portion having a female and a tip, the ferrule being located in the bore of the shaft at the first end of the shaft, the tip being removably connected to the ferrule;
- a joint insert located at the second end of the shaft configured to connect the shaft section to a joint collar and to a butt section of a cue;
- and
- a kinetic energy absorbing insert located in the bore of the shaft and contacting the bore of the shaft.
A kinetic energy absorbing insert for inserting into a bore of a shaft section of a cue used for billiards games comprising:
- a generally cylindrical body having a first end and a second end, wherein an insert length of the cylindrical body from the first end to the second end is less than a length of the bore of the shaft section, the cylindrical body having an insert diameter less than a bore diameter of the bore of the shaft section;
- an insert bore extending from the first end of the cylindrical body to the second end of the cylindrical body;
- and
- a plurality of circumferential protrusions extending radially outwardly from the cylindrical body, wherein a protrusion is disposed at the first end of the cylindrical body and a protrusion is disposed at the second end of the cylindrical body, and a plurality of protrusions are spaced equally therebetween, the protrusions defining a protrusion diameter, the protrusion diameter being equal to or greater than the bore diameter of the shaft section such that the protrusions contact the shaft section.
