Tubular exercise member having a wooden layer and a method for making the same

Abstract

A billiard cue includes a core made of foam material and a mediate layer wrapped around the core. The mediate layer includes fiber strips and wooden plates soaked with epoxide resin. A wooden layer is wrapped around the mediate layer. The cue is heated and pressurized by suitable molds to let the fiber strips and wooden plates be securely combined with each other. The foam core absorbs shocks and the wooden plates remain features of wooden billiard cues.

What is claimed is:  
     
         1 . A billiard cue comprising a shaft with a tip and a butt, the shaft comprising: 
 a core made of foam material;    a mediate layer wrapped around said core and comprising fiber strips and wooden plates, and a wooden layer wrapped around said mediate layer.    
     
     
         2 . The billiard cue as claimed in  claim 1  wherein the wooden layer includes a plurality of wooden plates which are wrapped onto said mediate layer.  
     
     
         3 . The billiard cue as claimed in  claim 1  wherein the wooden layer is a wooden tubular member which has a passage defined longitudinally therein, said core together with said mediate layer being received in said passage in said wooden tubular member.  
     
     
         4 . A method for manufacturing a billiard cue comprising the following steps: 
 step  1 : to prepare a core made of stiff material;    step  2 : to prepare fiber strips soaked with resin, wrapping said fiber strips onto said core to form a mediate layer on said core;    step  3 : to wrap wooden plates soaked with resin onto said mediate layer to form a wooden layer;    step  4 : to apply pressure onto said wooden layer;    step  5 : to heat said billiard cue in step  4  to solidify said resin to combine said fiber strips and said wooden plates;    step  6 : to cool down said cue after being treated in step  5  and remove said core to form a recess, and step  7 : to put foam material in said recess.    
     
     
         5 . The method as claimed in  claim 4 , wherein said core in step  1  is a metal rod.  
     
     
         6 . The method as claimed in  claim 4 , wherein said fiber layer in step  2  includes wooden plates and fiber strips which are alternatively wrapped onto said core.  
     
     
         7 . The method as claimed in  claim 4  further comprising a step  8  to grind and polish said wooden layer.
