Brief Patent Description - Full Patent Description - Patent Application Claims
CROSS-REFERENCE [0001] This present application claims priority to U.S. Provisional Application No. 60/740,731 filed Nov. 30, 2005 entitled "Billiard Cue And Method For Making The Same", the entire contents of which are specifically incorporated herein by reference. BACKGROUND [0002] The present invention relates to a billiard cue, and more particularly to a billiard cue with an improved shaft. [0003] Currently, billiard cues are made of natural wood due to the elasticity and stiffness of the natural wood. While billiard cues have been made from natural wood for years, the cues do suffer from some disadvantages such as warping due to moisture. Additionally, the weight distributed in a natural wood may be varied in different parts of the cue, which causes the hitting force of the cue to not be concentrated on the axis of the cue. As a result, the player is unable to hit the ball with precision. SUMMARY [0004] Embodiments of the invention include a billiard cue including: a wood shaft including a hollow portion and a solid portion, the hollow portion having a central bore extending a predetermined distance along the length of the shaft; and an hollow inner rod, wherein a length and outer diameter of the hollow inner rod correspond to the a length and inner diameter of the central bore, the hollow inner rod being disposed in the central bore. [0005] Embodiments of the invention also include a method for making a billiard cue including: creating a hollow portion by removing wood from the center of a wooden billiard cue; inserting a hollow metal rod into the hollow portion; and securing the hollow metal rod in the hollow portion. [0006] Other systems and methods according to an exemplary embodiments will be or become apparent to one with skill in the art upon review of the following drawings and detailed description. It is intended that all such additional systems and methods be included within this description, be within the scope of the present invention, and be protected by the accompanying claims. BRIEF DESCRIPTION OF THE DRAWINGS [0007] Referring now to the drawings wherein like elements are numbered alike in the several Figures: [0008] FIG. 1 illustrates an exemplary embodiment of a billiard cue; [0009] FIG. 2 illustrates another exemplary embodiment of a billiard cue; [0010] FIG. 3 illustrates a cross sectional view of an exemplary embodiment of a hollow metal tube; and [0011] FIG. 4 illustrates a flowchart of an exemplary embodiment of a method for constructing a billiard cue. DETAILED DESCRIPTION [0012] FIG. 1 depicts an exemplary embodiment of a billiard cue 10. The exemplary billiard cue 10 illustrated by FIG. 1 includes a shaft portion 18, a butt portion 20, and a tip 16. The shaft portion 18 and the butt portion 20 are fastened end to end together at a joint 24, as is commonly known in the art. In a first exemplary embodiment, the shaft portion 18 includes a hollow portion 12 and a solid portion 14. The solid portion 14 of the shaft portion 18 may be made of a nature wood, such as maple. A hollow metal tube 30 is disposed in the hollow portion 14 of the shaft portion 18. The hollow metal tube 30 may have an outer diameter such that the hollow portion 12 of the shaft portion 18 tightly receives the hollow metal tube 30. [0013] Referring still to FIG. 1, in another exemplary embodiment, the butt portion 20 includes a hollow portion 26 and a solid portion 28. The solid portion 26 of the butt portion 20 may be made of a nature wood, such as maple. A hollow metal tube 30 is disposed in the hollow portion 26 of the butt portion 20. The hollow metal tube 30 may have an outer diameter such that the hollow portion 26 of the butt portion 20 tightly receives the hollow metal tube 30. [0014] In a particular exemplary embodiment, the hollow metal tube 30 is made of titanium and has an outer diameter of approximately 0.25 inches and a wall thickness of approximately 0.02 inches. In another exemplary embodiment, the outer diameter of the hollow metal tube 30 is between about 0.125 inches and 0.04 inches, and the wall thickness is between about 0.01 inched and 0.05 inches. In a further exemplary embodiment, the weight of the hollow metal tube 30 in the shaft portion 18 is approximately equal to the weight of the wood removed from the shaft portion 18 to create the hollow portion 12. In another exemplary embodiment, the weight of the hollow metal tube 30 in the butt portion 20 is approximately equal to the weight of the wood removed from the butt portion 20 to create the hollow portion 12. In other words, the overall weight of the billiard cue 10 is the same weight as a traditional wooden cue. In a further exemplary embodiment, the hollow metal tube 30 is made of a titanium alloy, which for example may be AMS 4943 or AMS 1260, among others. It is also contemplated that other metals, including for example titanium alloys could be used in the construction of the hollow metal tube 30. [0015] FIG. 2 depicts an alternative exemplary embodiment of a billiard cue 110. The billiard cue includes a shaft 112, and a tip 116. Unlike the exemplary cue of FIG. 1, the illustrated cue 110 does not separate into halves, but is instead unitary along the bulk of its length. The billiard cue 110 includes a hollow portion 126 and a solid portion 128. The solid portion of the shaft portion 112 may be made of a natural wood, such as maple. A hollow metal tube 130 is disposed in the hollow portion 126 of the shaft portion 112. The hollow metal tube 30 has an outer diameter such that the hollow portion 126 of the shaft 112 tightly receives the hollow metal tube 30. [0016] In a particular exemplary embodiment, the hollow metal tube 130 is made of titanium and has an outer diameter of approximately 0.25 inches and a wall thickness of approximately 0.02 inches. In another exemplary embodiment, the outer diameter of the hollow metal tube 130 is between about 0.125 inches and 0.04 inches, and the wall thickness is between about 0.01 inched and 0.05 inches. In an additional exemplary embodiment, the weight of the hollow metal tube 130 is approximately equal to the weight of the wood removed from the shaft 112 to create the hollow portion 126. In other words, the overall weight of the billiard cue 110 is the same weight as a traditional wooden cue. [0017] FIG. 3 depicts a cross sectional view of the hollow metal tube 30. In an exemplary embodiment, the outer diameter 32 is between about 0.22 inches and 0.35 inches, and the wall thickness 34 is between about 0.01 inched and 0.05 inches. The hallow metal tube 30 may be constructed of titanium, which for example may be AMS 4943 or AMS 1260, among others. It will be appreciated that the hallow metal tube 30 may be constructed of various other metals or alloys that have roughly similar properties (e.g., hardness). Additionally, the hollow metal tube 30 may be any desired length depending upon the type of cue and the length of the opening inside of the cue. Furthermore, in a two piece cue construction, rather than only incorporating a tube in one piece, e.g. the shaft portion, two hollow metal tubes may be utilized, one in each piece of the cue. [0018] FIG. 4 is a flow diagram depicting an exemplary method 200 for making the billiard cue 10. A similar method can also be used to make the billiard cue 110, which is a single piece cue. The method for making the billiard cue 200 includes removing wood from the center of a standard wooden billiard cue to create a hollow portion. The method for making the billiard cue 200 also includes inserting a hollow metal rod inside the hollow portion of the billiard cue. The metal rod is secured inside the hollow portion. In an exemplary embodiment, the hollow metal rod has approximately the same weight as the wood removed from the billiard cue. [0019] In exemplary embodiments, removing wood from the center of a traditional billiard cue and inserting the hollow metal tube 30 into the cue provides an improved billiard cue 10. The improved billiard cue 10 provides a more solid strike of the ball as compared to the traditional cue due to its composition. Additionally, the improved billiard cue 10 may be designed such that the overall weight of the improved billiard cue 10 is identical to that of a traditional billiard cue. Furthermore, the hollow metal tube 30 provides additional benefits over the traditional cue, such as the reduction of warping of the improved billiard cue over time.
