Golf Club

Abstract

A golf club includes a shaft body, a head body connected to the shaft body, and a thermochromic portion provided on at least one of the shaft body and the head body and including a thermochromic blend. The thermochromic blend is made by blending a coating material or a molding material with a thermochromic material.

1 . A thermochromic golf club shaft, comprising:
 a shaft body; and   a thermochromic portion provided on said shaft body, and including a thermochromic blend.   
   
   
       2 . The thermochromic golf club shaft as claimed in  claim 1 , wherein said thermochromic blend includes a coating material and a thermochromic material, said thermochromic portion being a coating layer applied on said shaft body. 
   
   
       3 . The thermochromic golf club shaft as claimed in  claim 1 , wherein said thermochromic blend includes a molding material and a thermochromic material, and said thermochromic portion is a preform sleeved on said shaft body. 
   
   
       4 . The thermochromic golf club shaft as claimed in  claim 2 , wherein said coating material is selected from the group consisting of ink and clear lacquer, and said thermochromic material is a thermochromic powder. 
   
   
       5 . The thermochromic golf club shaft as claimed in  claim 2 , wherein a weight ratio of said thermochromic material to said coating material ranges from 1:3 to 1:5. 
   
   
       6 . The thermochromic golf club shaft as claimed in  claim 4 , wherein said coating material is clear lacquer, and said thermochromic portion is formed by coating said thermochromic blend on said shaft body. 
   
   
       7 . The thermochromic golf club shaft as claimed in claim  4 , wherein said coating material is ink, and said thermochromic portion is formed by printing said thermochromic blend on said shaft body. 
   
   
       8 . The thermochromic golf club shaft as claimed in  claim 3 , wherein said molding material is selected from the group consisting of thermoplastic polyurethane, silica gel, and acrylonitrile-butadiene-styrene copolymer, and said thermochromic material is a thermochromic powder. 
   
   
       9 . The thermochromic golf club shaft as claimed in  claim 3 , wherein a weight ratio of said thermochromic material to said molding material ranges from 1:190 to 1:120. 
   
   
       10 . The thermochromic golf club shaft as claimed in  claim 1 , wherein said thermochromic blend has a thermochromic temperature ranging from −15° C. to 70° C. 
   
   
       11 . A thermochromic golf club head, comprising:
 a head body having a thermochromic portion that includes a thermochromic blend.   
   
   
       12 . The thermochromic golf club head as claimed in  claim 11 , wherein said thermochromic blend includes a coating material and a thermochromic material, said thermochromic portion being a coating layer applied on said head body. 
   
   
       13 . The thermochromic golf club head as claimed in  claim 11 , wherein said thermochromic blend includes a molding material and a thermochromic material, and said thermochromic portion is a preform covered on said head body. 
   
   
       14 . The thermochromic golf club head as claimed in  claim 12 , wherein said coating material is selected from the group consisting of ink and clear lacquer, and said thermochromic material is a thermochromic powder. 
   
   
       15 . The thermochromic golf club head as claimed in  claim 12 , wherein a weight ratio of said thermochromic material to said coating material ranges from 1:3 to 1:5. 
   
   
       16 . The thermochromic golf club head as claimed in  claim 14 , wherein said coating material is clear lacquer, and said thermochromic portion is formed by coating said thermochromic blend on said head body. 
   
   
       17 . The thermochromic golf club head as claimed in  claim 14 , wherein said coating material is ink, and said thermochromic portion is formed by printing said thermochromic blend on said head body. 
   
   
       18 . The thermochromic golf club head as claimed in  claim 13 , wherein said molding material is selected from the group consisting of thermoplastic polyurethane, silica gel, and acrylonitrile-butadiene-styrene copolymer, and said thermochromic material is a thermochromic powder. 
   
   
       19 . The thermochromic golf club head as claimed in  claim 13 , wherein a weight ratio of said thermochromic material to said molding material ranges from 1:190 to 1:120. 
   
   
       20 . The thermochromic golf club head as claimed in  claim 13 , wherein said head body is composed of at least two component parts assembled together, said perform being formed as at least one of said component parts. 
   
   
       21 . The thermochromic golf club head as claimed in  claim 11 , wherein said thermochromic blend has a thermochromic temperature ranging from −15° C. to 70° C. 
   
   
       22 . A golf club, comprising:
 a shaft body;   a head body connected to said shaft body; and   a thermochromic portion provided on at least one of said shaft body and said head body, and including a thermochromic blend.
