Benefits of technology

[0007] An object of the present invention is to provide a golf club head with elastic weight members for improving the vibration-absorbing effect of the golf club head while adjusting the center of gravity of the golf club head.
[0008] Another object of the present invention is to provide a golf club head with elastic weight members in which the engaging reliability between the golf club head and the elastic weight members is improved. SUMMARY OF THE INVENTION
[0010] The first elastic weight member and the second elastic weight member are mounted in the assembling portion of the body to form a golf club head. The first elastic weight member and the second elastic weight member adjust a center of gravity of the golf club head and provide an elastic vibration-absorbing effect.
[0022] The elastic weight member and the elastic member are mounted in the assembling portion of the body to form a golf club head. The elastic weight member and the elastic member adjust a center of gravity of the golf club head and provide an elastic vibration-absorbing effect.

Problems solved by technology

Although the center of gravity of each of the above-mentioned golf club head can be adjusted, the vibration generated during striking could not be effectively absorbed, as the weight member (or weighting bottom plate) does not provide a vibration-absorbing function.
As a result, the golf club head might crack or the weight member (or weighting bottom plate) might be disengaged from the body after a period of time regardless of the engaging method (such as welding, brazing, insertion, screwing, etc) between the body and the weight member / weighting bottom plate.

first embodiment

[0042] Referring to FIGS. 1 and 2, a golf club head in accordance with the present invention comprises a body 1, a first elastic weight member 2, and a second elastic weight member 3. The body 1 may be a body for an iron club head, a wood club head, or a putter. The first and second elastic weight members 2 and 3 are used to adjust the center of gravity of the golf club head while providing a vibration-absorbing effect for the golf club head.

[0043] In the illustrated embodiment, the body 1 is for an iron club head. The body 1 is made of metal, alloy, or non-metal material. The body 1 includes a striking plate 11, a hosel 12, and a cavity. 13. The striking plate 11 and the hosel 12 may be of a conventional design and can be mounted to the body 1 by welding, brazing, insertion, screwing, or bonding. The striking plate 11 has a front side for striking golf balls. Alternatively, the body 1, the hosel 12, and the striking plate 11 can be integrally formed, with the striking plate 11 prov...

second embodiment

[0051]FIG. 3 illustrates the invention, wherein the first elastic weight member 2 and the second elastic weight member 3 are assembled in a different manner. In this embodiment, the second elastic weight member 3 is pre-manufactured and then fixed to a bottom wall delimiting the cavity 13 of the body 1 by bonding or insertion. Next, a mixture of the elastic matrix and the metal powder are injected into the cavity 13 to form the first elastic weight member 2 (injection molding). Thus, the second elastic weight member 3 is partially embedded in the first elastic weight member 2. This arrangement improves the assembling reliability of the first elastic weight member 2 and the second elastic weight member 3 while allowing absorption of the vibration and the adjustment of the center of gravity of the golf club head.

[0052]FIG. 4 illustrates a third embodiment of the invention modified from the second embodiment. In this embodiment, a metal weight member 31 is embedded in the second elasti...

fifth embodiment

[0054]FIG. 6 illustrates the invention. In this embodiment, the body 1 is for a wood club head. The body 1 comprises a striking plate 11, a hosel 12, and an inner space 10 that provides an assembling portion for mounting at least two elastic weight members. The first and second elastic weight members 2 and 3 may be mounted in an appropriate location of the inner space 10 of the body 1. At least one of the first and second elastic weight members 2 and 3 (e.g., the first elastic weight member 2) is in contact with the rear side of the striking plate 11 to provide a vibration-absorbing function and to increase the coefficient of restitution of the striking plate 11.

Abstract

A golf club head includes a body having a striking plate and an assembling portion, a first elastic weight member including an elastic matrix and a metal powder mixed in the elastic matrix, and a second elastic weight member including an elastic matrix and a metal powder mixed in the elastic matrix of the second elastic weight member. The second elastic weight member includes a specific density and an elastic coefficient different from those of the first elastic weight member. The first elastic weight member and the second elastic weight member are mounted in the assembling portion of the body to form a golf club head. The first elastic weight member and the second elastic weight member adjust a center of gravity of the golf club head and provide an elastic vibration-absorbing effect.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a golf club head. In particular, the present invention relates to a golf club head with weight members. [0003] 2. Description of Related Art [0004] Taiwan Utility Model Publication No. 322789 discloses a golf club head allowing adjustment of the center of gravity. The golf club head comprises a body made of metal and including a hosel, a crown, a sole, and a rear. At least one cavity is defined in the crown, the sole, and / or the rear. A weight member is mounted into the cavity by plastic deformation and thus coupled to the body as an integral unit. The material, specific density, mass, and volume of the weight member are selected to adjust the center of gravity of the golf club head to a desired location. [0005] China Utility Model Publication No. CN 2429210 Y discloses a golf club head comprising a body and a weighting bottom plate. The body is made of a material having a low specif...
