Golf club head with strength-enhanced rear body

Abstract

A golf club head with strength-enhanced rear body comprises a front body, a rear body and at least one supporting member. The front body comprises a face and a plurality of abutting edges. The rear body comprises a crown, a ribbon and a plurality of abutting edges, with the rear body being made of a nonmetal material having a specific gravity lower than that of the front body, and the abutting edges of the rear body being corresponding to and connecting with those of the front body. The at least one supporting member being made of a light alloy is disposed along a border between the crown and the ribbon of the rear body.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a golf club head having a strength-enhanced rear body; and particularly, to a rear body receiving at least one supporting member, with the rear body being combined with a front body to form a golf club head and the rear body being made of engineering plastic, so as to enhance the structural strength of the golf club head.[0003]2. Description of the Related Art[0004]A conventional golf club head with a strength-enhanced member, as described in U.S. Pat. No. 6,672,975, entitled “Golf Club Head”, includes a body made of a light metal having a density lower than 4.5 g / cm3 or a nonmetal such as polycarbonate, a striking plate, and a supporting frame. The body comprises an opening disposed at the front side of the body for engaging with the striking plate correspondingly, a neck hole for connecting to a shaft, and a plurality of engaging grooves arranged on an outer surface of the body.

AI Technical Summary

Benefits of technology

"The present invention provides a golf club head with a strength-enhanced rear body. The rear body is made of engineering plastic and combined with a front body to jointly form a golf club head. The total weight of the golf club head is low while its structural strength is enhanced. The rear body contains organic short fibers which further enhances its structural strength and longevity. The golf club head has a front body with abutting edges, a rear body with a crown, ribbon, and abutting edges, and at least one supporting member made of a light alloy. The nonmetal material can be either crystalline or amorphous engineering plastic. The rear body also has a rear sole and integrally formed with the crown, ribbon, and neck. The front body further comprises a front sole connecting to a sole portion of the sidewall by welding. A weight member can also be provided on the inner surface of the front sole."

Problems solved by technology

Nevertheless, said conventional golf club head has several drawbacks.

In order to reduce the total weight of the golf club head, a selected light material is used to form the body and the supporting frame is applied to enhance the structural strength of the body; however, the processes to form the engaging grooves on the outer surface of the body for receiving the supporting frame is complex.

And because the engagement between the striking plate and the supporting frame is merely provided by the screws and thread holes, the reliability of the combination between the body, the striking plate, and the supporting frame is low.

Furthermore, owing to the light material applied to form the body, a weight difference between a sole portion and a crown portion of the body is absent, which leads to a high center-of-gravity position of said conventional golf club head.
