Composite Golf Club Head

The present invention relates to a golf club head and, more particularly, to a composite (or combined) golf club head.

In general, golf clubs are mainly divided into wood, hybrid, iron, wedge, putter and chipper according to different uses and characteristics. A golf club is made of material, such as wood, titanium alloy and carbon fiber. The golf club includes a head and a shaft connected with the head. The head has a connection for mounting the shaft. The golf club head is the main structure that is used to hit a golf ball. Thus, various precise calculations and designs are needed according to the weight, shape, material, and impact of the golf club head. More specifically, a variety of material are mixed to meet diverse requirements of the golf club head.

In fabrication, the connection of the golf club head needs to have a strong structure, to effectively transmit a force, and to withstand an impact. In addition, the front end of the golf club head is used to hit the golf ball so that the front end usually has a flat or cup shape. Further, the rear end (or tail portion) of the golf club head needs to consider problems of aerodynamics and counterweight. Thus, the whole structure, stress, and counterweight of the golf club head have to be designed precisely. However, different users will have different usage habits so that the golf club head of the same type is not suitable for all users. Thus, the manufacturer has to make golf club heads of different types to satisfy the requirements of different users, thereby greatly increasing the cost of fabrication, production, and inventory. In addition, the consumers' choices are also limited.

A conventional golf club head includes a tail portion that is made of carbon fiber so that the golf club head has a lighter weight. The tail portion includes an inner skeleton made of titanium alloy or aluminum alloy. The inner skeleton includes multiple curved sheet plates which are bonded together. Each of the curved sheet plates is made of hot-pressed carbon fiber. Thus, the weight of the tail portion is limited. In addition, the upper part and the lower part of the tail portion of the golf club head have to be separated and then adhered to construct hot-pressed carbon fiber curved sheet plates, thereby decreasing the structural strength and increasing the cost of fabrication.

The primary objective of the present invention is to provide a composite golf club head that is customized and modularized in mass production.

In accordance with the present invention, there is provided a composite golf club head comprising a head body, a batting member, and a tail member. The head body includes a hollow frame and a shaft connecting portion extending from an upper end of the hollow frame. The hollow frame has a front provided with a first positioning portion. The hollow frame has a back provided with a second positioning portion. The batting member has a front provided with a batting face. The batting member has a back provided with a first connecting portion. The first connecting portion is secured on the first positioning portion. The tail member is formed integrally by carbon fiber. The tail member has a half-cover shell structure with an opening directed forward. The tail member has a front provided with a second connecting portion. The second connecting portion is secured on the second positioning portion.

Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

Preferably, the second connecting portionis secured on the second positioning portionby gluing or screwing.

In the preferred embodiment of the present invention, the hollow frame(or the head body) is formed integrally by a titanium alloy, and the second connecting portionhas a shape matching that of the second positioning portion.

In another preferred embodiment of the present invention, the hollow frame(or the head body) is formed integrally by carbon fiber.

In the preferred embodiment of the present invention, the batting memberis formed integrally by a titanium alloy, and the first connecting portionhas a shape matching that of the first positioning portion.

In another preferred embodiment of the present invention, the batting memberis formed integrally by carbon fiber.

In the preferred embodiment of the present invention, the composite golf club headfurther comprises a weightsecured on the tail member.

In the preferred embodiment of the present invention, the tail memberis provided with a weight cavity, and the weightis secured in the weight cavity. Preferably, the weight cavityis located at a lower end of a back of the tail member, and the weightis removably mounted in the weight cavity.

In the preferred embodiment of the present invention, the head bodyhas an outer surface provided with a recessed portion.

In the preferred embodiment of the present invention, the recessed portionis located at an exterior of a lower end of the head bodyand has a strip shape. Preferably, the recessed portionis used to add a counterweight or an ornament.

In the preferred embodiment of the present invention, the second positioning portionis provided with a groovealigning with the second connecting portion. A glue is filled into the groovefor adhering the second connecting portion, so that the tail memberis secured to the head body.

In the preferred embodiment of the present invention, the carbon fiber of the tail memberis directly formed by one-time hot pressing. Thus, the tail memberis not formed by multiple pieces which are bonded together.

In assembly, the head body, the batting member, and the tail memberare assembled to construct the composite golf club head. In such a manner, the material of the head body, the batting member, and the tail membercan be selected freely and arbitrarily according to the requirement of a practical use. In addition, the weightis selectively mounted on the tail member. Thus, the composite golf club headis customized and modularized in mass production, to reduce the amount and cost of the inventory and to increase the profit of the industry.

Preferably, the head bodyis formed by a titanium alloy, the batting memberis formed by a titanium alloy, and the tail memberis formed by carbon fiber. Alternatively, the head bodyis formed by a titanium alloy, the batting memberis formed by carbon fiber, and the tail memberis formed by carbon fiber. Alternatively, the head bodyis formed by carbon fiber, the batting memberis formed by a titanium alloy, and the tail memberis formed by carbon fiber. Alternatively, the head bodyis formed by carbon fiber, the batting memberis formed by carbon fiber, and the tail memberis formed by carbon fiber.

Referring towith reference to, the batting memberhas a different shape and is embedded in the front end of the head body. The batting memberhas a back provided with a first connecting portionwhich has a shape matching that of the first positioning portion. The first connecting portionis secured on the first positioning portion. Preferably, the first connecting portionis secured on the first positioning portionby gluing.
