1. Field of the Invention
The invention relates to a golf club, more particularly to a golf club having thermochromic function.
2. Description of the Related Art
When purchasing a golf club, consumers may consider aesthetic and textural aspects thereof in addition to normal functions. Therefore, it is desirable in the art to develop a golf club which includes a golf club shaft or head having an improved appearance and texture.
Therefore, the object of the present invention is to provide a golf club including at least one of a thermochromic golf club shaft and a thermochromic golf club head.
In one aspect of this invention, a thermochromic golf club shaft includes a shaft body, and a thermochromic portion provided on the shaft body and including a thermochromic blend.
In another aspect of this invention, a thermochromic golf club head includes a head body having a thermochromic portion that includes a thermochromic blend.
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings, of which:
Before the present invention is described in greater detail, it should be noted that like elements are denoted by the same reference numerals throughout the disclosure.

Preferably, the coating material is ink or clear lacquer, and the thermochromic material is composed of thermochromic powders having a particle size of about 0.01 mm. The weight ratio of the thermochromic material to the coating material preferably ranges from 1:3 to 1:5. The thermochromic blend has a thermochromic temperature preferably ranging from −15° C. to 70° C.
When the coating material is clear lacquer, the thermochromic portions 12 are formed by coating the thermochromic blend on the shaft body 11. The thermochromic portions 12 can be a trademark pattern or any other patterns. When the coating material is ink, the thermochromic portions 12 are formed by printing (e.g., transfer printing or screen printing) the thermochromic blend on the shaft body 11 and by laser engraving the thermochromic blend printed on the shaft body 11.
The thermochromic powders can be selected according to the desired specific thermochromic color of the thermochromic portions 12. The thermochromic temperature range of the thermochromic portions 12 depends on the specific thermochromic powders. Furthermore, different thermochromic powders can be used in the thermochromic portions 12, if desired, so as to produce multiple thermochromic effects.
