Method for manufacturing rackets with shock absorbing members with single heating process

Abstract

A method for manufacturing racket with shock absorbing members includes step 1 to form a shaft having two extensions by composite prepreg material; step 2 to wrap two respective shock absorbing members on the two extensions; step 3 to form a head having two tubular portions extending therefrom by composite prepreg material, and steps 4 to insert the two extensions wrapped with the shock absorbing members in the two tubular portions and to heat the combination in a mold.

What is claimed is:  
     
         1 . A method for manufacturing racket with shock absorbing members, comprising the following steps: 
 step 1: preparing a shaft by composite prepreg material and the shaft having two extensions extending from one of two ends thereof;    step 2: wrapping two respective shock absorbing members on the two extensions;    step 3: preparing a head by composite prepreg material and the head having two tubular portions extending therefrom ; {overscore (,)}   steps 4: inserting the two extensions wrapped with the shock absorbing members in the two tubular portions, and    step 5: heating the combination in step 4 in a mold under pressure.    
     
     
         2 . The device as claimed in  claim 1 , wherein the shock absorbing members have a  Shore  hardness number of 30 to 80.  
     
     
         3 . A method for manufacturing racket with shock absorbing members, comprising the following steps: 
 step 1: preparing a head having a throat portion and a connectio n  section extending from the throat portion, the head, the throat portion and the connection section made by composite prepreg material;    step 2: wrapping a shock absorbing member on the connection section;    step 3: preparing a shaft which has an opening defined in one of two ends thereof, the shaft made by composite prepreg material ; {overscore (,)}   step 4: inserting the connection section wrapped with the shock absorbing member in the opening of the shaft, and    step 5: heating the combination in step 4 in a mold under pressure.    
     
     
         4 . The device as claimed in  claim 3 , wherein the shock absorbing member has a  Shore  hardness number of 30 to 80.
