Shock-absorbing golf-club head

[0002] This invention relates to a shock-absorbing golf club head, particularly to one having a double-deck shock-absorbing layer to effectively absorb wrenching and shock force caused by hitting to achieve effective shock-absorbing, shock-lessening, and stability of ball-controlling.

[0003] Generally, when a golfer swings a golf club in striking a ball, the striking face of the golf club will give rise to a kind of wrenching and shock force, which may hurt a golfer's wrists.

[0004] In order to eliminate such drawbacks, some conventional golf club heads are integrally provided with a shock-absorbing layer for absorbing the wrench and shock force caused by hitting. U.S. Pat. No. 5,772,527 is a typical example.

[0005] In accordance with U.S. Pat. No. 5,772,527, the striking face 21 of a golf club head 2 is provided with a recess 22 having projections 23 around a front circumferential edge to be fixedly mounted with a metal face plate 25 by welding, sealing the recess 22 and forming an intermediate hollow with a slot 24 on an upper edge for injecting shock-absorbing material into the recess 22 to form a shock-absorbing layer 1, as shown in FIGS. 1, 2, and 3.

[0006] However, the wrench and shock force of a golf club head caused by hitting takes place instantly and spreads so quickly that it can hardly be absorbed completely by the single shock-absorbing layer inside the striking face of the golf club head.

[0007] The objective of this invention is to offer a golf club head having a double layer for shock absorbing, able to effectively absorb the wrench and shock force caused by hitting, enabling a golfer to acquire stability of ball controlling.

[0008] This invention will be better understood by referring to the accompanying drawings, wherein:

[0009] FIG. 1 is a perspective view or a known conventional golf club head with a metal faceplate separated:

[0010] FIG. 2 is a perspective view of the known conventional golf club head:

[0011] FIG. 3 is a side cross-sectional view of the known conventional golf club head.

[0012] FIG. 4 is an exploded perspective view of a golf club head with a metal faceplate separated in the present invention:

[0013] FIG. 5 is a rear view of the golf club head half completed in the present invention.

[0014] FIG. 6 is a front view of the golf club head in the present invention:

[0015] FIG. 7 is a rear view of the golf club head in present invention:

[0016] FIG. 8 is a vertical side cross-sectional view of the golf club head in the present invention: and

[0017] FIG. 9 is a horizontal side cross-sectional view of the golf club head in the present invention.

[0018] A preferred embodiment of a shock-absorbing golf club head in the present invention, as shown in FIGS. 4 and 5, includes a front recess 32 in the striking face of a golf club head, extending to the top and the rear portions of the striking face and communicating with a rear recess 33 by means of a plurality of through holes 321. Then, a shock-absorbing layer 4 is formed into shape and affixed to the front and the rear recesses 32 and 33, and a metal face plate 34 is fixedly mounted on the front recess 32, having a dented portion around its circumferential edge fixed with the striking face synchronously when the shock-absorbing layer 4 is formed and affixed to the front and the rear recess 32 and 33, as shown in FIGS. 6, 7, 8, and 9.

[0019] In addition, the shock-absorbing layer 4 is formed by compression with shock-absorbing material such as pure rubber or thermoplastic elastomers (so called TPE).

[0020] Further, FIG. 8 shows that the front and the rear recesses 32, 33 are respectively provided with a shock-absorbing layer 4 formed integrally to make up a double layer for shock-absorbing. With this design, the front shock-absorbing layer 4 in the striking face can directly absorb or lessen the wrench and shock force caused by hitting, and subsequently the rear shock-absorbing layer 4 in the rear recess 33 will completely absorb or eliminate the remaining shock force, thus obtaining an effectiveness of shock-absorbing, shock-lessening and stability of controlling balls.

[0021] While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
