Cue shaft with ball control enhancement function and billiard cue thereof

Abstract

A cue shaft with ball control enhancement function and a billiard cue thereof are provided. The cue shaft includes an outer tube and a combine end. The outer tube includes a strike end and a combine end disposed in opposite to the strike end, with a housing space formed between the strike end and the combine end. The housing space is disposed along an axial direction of the outer tube. The combine end is configured to be combined with the cue butt. The inner member has a length and is disposed in the housing space, such that an outer edge of the inner member fits an inner edge of the outer tube. Therefore, with the cue shaft not being a singular component, the ball controlling stability is improved, thus achieving an optimal ball striking performance.

1 . A cue shaft with ball control enhancement function, which is combined with a cue butt of a billiard cue, the cue shaft comprising:
 an outer tube comprising a strike end and a combine end disposed in opposite to the strike end, with a housing space formed between the strike end and the combine end, the housing space being disposed along an axial direction of the outer tube, and the combine end being configured to be combined with the cue butt, the outer tube being a combination tube formed of a plurality of wooden components arranged around an axial direction of the cue shaft, and the components being connected in a side-by-side manner, such that the outer wall of the outer tube formed by the components presents a smooth peripheral wall along the axial direction of the cue shaft without step structures thereon; and   an inner member having a length and disposed in the housing space and placed away from the combine end, an outer edge of the inner member and an inner edge of the outer tube having a sectional face formed in a circular shape, such that an outer wall of the inner member is fully surrounded by the outer tube.   
     
     
         2 . The cue shaft of  claim 1 , further comprising a strike assembly configured to be combined with the strike end, the strike assembly comprising a tip and a fix member, the fix member mounted on the strike end, and the tip disposed on an end of the fix member away from the strike end. 
     
     
         3 . The cue shaft of  claim 2 , further comprising a medium member disposed between the tip and the fix member. 
     
     
         4 . (canceled) 
     
     
         5 . The cue shaft of  claim 1 , wherein a sectional face of the inner member is formed in a shape chosen from a group consisting of a solid circle and a hollow circle. 
     
     
         6 . The cue shaft of  claim 5 , wherein at least one end of the inner member comprises a distal member. 
     
     
         7 . The cue shaft of  claim 6 , wherein the distal member is made of polyurethane material. 
     
     
         8 . The cue shaft of  claim 1 , wherein the inner member is made of carbon fiber. 
     
     
         9 . The cue shaft of  claim 1 , wherein two inner members are included, and the two inner members are mutually spaced with each other and disposed in the outer tube along the axial direction of the outer tube. 
     
     
         10 . The cue shaft of  claim 1 , further comprising a filler disposed between the strike end and the inner member. 
     
     
         11 . The cue shaft of  claim 10 , wherein the filler is made of a material chosen from a group consisting of polyurethane and wood. 
     
     
         12 . A billiard cue including a cue shaft and a cue butt screwedly combined with the cue shaft, the cue shaft comprising:
 an outer tube comprising a strike end and a combine end disposed in opposite to the strike end, with a housing space formed between the strike end and the combine end, the housing space being disposed along an axial direction of the outer tube, and the combine end being configured to be combined with the cue butt, the outer tube being a combination tube formed of a plurality of wooden components arranged around an axial direction of the cue shaft, and the components being connected in a side-by-side manner, such that the outer wall of the outer tube formed by the components presents a smooth peripheral wall along the axial direction of the cue shaft without step structures thereon; and   an inner member having a length and disposed in the housing space and placed away from the combine end, an outer edge of the inner member and an inner edge of the outer tube having a sectional face formed in a circular shape, such that an outer wall of the inner member is fully surrounded by the outer tube.
