Golf club head having a cushion channel formed with a varied width and manufacturing method therefor

Abstract

A golf club head includes a cushion channel varying in width. The manufacturing method therefor includes the steps of: forming a through hole on a surface of a main body; preparing a carbon-fiber plate formed by carbon-fiber fabrics; providing the cushion channel between an inner periphery of the through hole and an outer periphery of the carbon-fiber plate when assembled, and permitting the cushion channel to form a varied width; filling filler into the varied width of the cushion channel; precision finishing the surface of the main body to thereby produce the final product of the golf club head.

1 . A manufacturing method for a golf club head comprising the steps of: 
 forming at least one through hole on a surface of a main body;    preparing a carbon-fiber plate formed by carbon-fiber fabrics;    providing a cushion channel between an inner periphery of the through hole and an outer periphery of the carbon-fiber plate when assembled, and permitting the cushion channel to vary in widths; and    filling filler into the cushion channel.

       3 . The welding method for manufacturing the golf club head as defined in  claim 1 , wherein a stepped portion is formed on the inner periphery of the through hole for adhering to the carbon-fiber plate.  
   
   
       4 . The manufacturing method for the golf club head as defined in  claim 3 , wherein when the carbon-fiber plate is adhered to the stepped portion of the through hole, the cushion channel is formed on the outer periphery of the carbon-fiber plate by CNC milling.  
   
   
       5 . The manufacturing method for the golf club head as defined in  claim 3 , wherein when the carbon-fiber plate is adhered to the stepped portion on the through hole, the cushion channel is formed on the inner periphery of the through hole by CNC milling.  
   
   
       6 . The manufacturing method for the golf club head as defined in  claim 1 , wherein a first stepped portion and a second stepped portion are formed on the through hole, the first stepped portion is provided for adhering to the carbon-fiber plate; and the cushion channel is formed by the inner periphery of the through hole, the second stepped portion, and the outer periphery of the carbon-fiber plate.  
   
   
       7 . The manufacturing method for the golf club head as defined in  claim 6 , wherein the first stepped portion and the second stepped portion are integrally formed on the through hole of the main body by casting.  
   
   
       8 . The manufacturing method for the golf club head as defined in  claim 1 , wherein a size of the carbon-fiber plate is smaller than that of the through hole, and a plurality of short fingers are provided on the outer periphery of the carbon-fiber plate and extended outwardly to confront with the inner periphery of the through hole so as to form the cushion channel therebetween such that the carbon-fiber plate positioned in the through hole precisely defines the cushion channel.  
   
   
       9 . The manufacturing method for the golf club head as defined in  claim 8 , wherein the short fingers are formed on the outer periphery of a large-size periphery of the carbon-fiber plate by CNC milling.  
   
   
       10 . The manufacturing method for the golf club head as defined in  claim 1 , wherein the filler is selected from an elastic colored material.  
   
   
       11 . The manufacturing method for the golf club head as defined in  claim 1 , wherein the filler is selected from non-metal material.  
   
   
       12 . The manufacturing method for the golf club head as defined in  claim 1 , wherein The carbon-fiber plate can be replaced by another non-metal plate with low weight and high strength.  
   
   
       13 . The manufacturing method for the golf club head as defined in  claim 1 , wherein the cushion channel of the golf club head has at least one turning point where the cushion channel is varying in width.  
   
   
       14 . The manufacturing method for the golf club head as defined in  claim 1 , wherein the cushion channel of the golf club head has a relatively greater width at a predetermined position adjacent to or beyond a striking plate.  
   
   
       15 . A golf club head, comprising: 
 a main body provided with a striking plate, a crown plate, a sole plate, a side plate;    the main body is formed with at least one through hole;    at least one carbon-fiber plate formed by carbon-fiber fabrics, the carbon-fiber plate is adapted to adhere to the through hole;    a cushion channel formed between an outer periphery of the carbon-fiber plate and an inner periphery of the through holes, said cushion channel varying in width; and    a filler filled in the cushion channel.    
   
   
       16 . The golf club head as defined in  claim 15 , wherein a stepped portion is formed on the inner periphery of the through hole for adhering to the carbon-fiber plate.  
   
   
       17 . The golf club head as defined in  claim 15 , wherein a first stepped portion and a second stepped portion are formed on the through hole, the first stepped portion is provided for adhering to the carbon-fiber plate; and the cushion channel is formed by the inner periphery of the through hole, the second stepped portion, and the outer periphery of the carbon-fiber plate.
