Laminated inner structure of wooden billiard cue

Abstract

The present invention provides a kind of Laminated Inner Structure of Wooden Billiard Cue, through which a tubal auxiliary part of proper length and thickness was designed, so that it would make the external main body have proper efficacy in shaping based on high hardness of the auxiliary part and overcome the defect of easy deformation, further better the application efficacy.

1 . A kind of Laminated Inner Structure of Wooden Billiard Cue with one minimal outer part which is located on the end of shaft of pole; a shaft hole with designed diameter was designed in the interior of main body, and it extends to the designed depth along the shaft. The designed diameter of hole would be less than 70% of minimal outer diameter. Additionally, a straight tubal auxiliary part with designed length which made of composite materials was designed and fixed through the hole.  
   
   
       2 . According to the Laminated Inner Structure of Wooden Billiard Cue described in claims  1 , in which this main body of billiard cue is combined one first and second pole connected each other with same shaft.  
   
   
       3 . According to the Laminated Inner Structure of Wooden Billiard Cue described in claims  1 , in which, its composite material is carbon fiber.  
   
   
       4 . According to the Laminated Inner Structure of Wooden Billiard Cue described in claims  1 , in which, its composite material is fiberglass.  
   
   
       5 . According to the Laminated Inner Structure of Wooden Billiard Cue described in claims  1 , in which, the outer diameter of the auxiliary part matches the diameter of shaft hole.
