Abstract

A striking face of a golf club includes a rear face with variedvaried thickness distribution. The rear face is divided into eight sections with an imaginary transverse line, a perpendicular line and two diagonal lines. The rear face has a joint position where the imaginary transverse line, perpendicular line and two diagonal lines join, and a joint where the rear face is adapted to engage with the golf club. The joint position has a maximum thickness, an inner peripheral edge of the joint engaging with the imaginary transverse line and the perpendicular line has a medium thickness and the inner peripheral edge of the joint engaging with the diagonal lines has a minimum thickness.

Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention [0001]
  • The present invention relates to a golf club striking face, and more particularly to a golf club striking face with varied thickness distribution so that when striking a golf ball with an area other than the sweet spot of the striking face, the golf ball is able to travel a distance the same as that by striking the golf ball with the sweet spot. [0002]
  • 2. Description of Related Art [0003]
  • Numerous patents and products are introduced to the market to improve the golf ball travelling distance. Some use a hollow golf club with an alloy encased in the hollow golf club and some change the angle of the striking face. All these changes try to make the golf ball to have the maximum travelling distance. However, the maximum travelling distance of the golfball only happens when the golfer strikes the golf ball with the sweet spot of the striking face. As well known in the art, golfers will have their best performances only when striking the golf ball with the sweet spot. After striking the golf ball with the sweet spot, the golf ball will fly toward the designated direction. [0004]
  • However, due to the conditions of the golf course, the physical conditions of the golfers, etc, even a professional golfer can not guarantee that every strike is a perfect hit. Therefore, mis-hits of the golf ball happen a lot during play on the golf course, especially to those who just begin to play golf. [0005]
  • To overcome the shortcomings, the present invention tends to provide an improved golf club striking face to mitigate and obviate the aforementioned problems. [0006]
  • SUMMARY OF THE INVENTION
  • The primary objective of the present invention is to provide an improved golf club striking face with varied thickness distribution so that when striking a golfball with an area other than the sweet spot of the striking face, the golf ball can travel a distance the same as that of striking the golf ball with the sweet spot. [0007]
  • Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.[0008]
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is a perspective view of a rear side of the striking face of a golf club of the present invention; [0009]
  • FIG. 2 is a plan view of the rear side of the striking face of the present invention; [0010]
  • FIGS. 3A, 3B and [0011] 3C are cross sectional views of the striking face by taking lines A-A, B-B and C-C in FIG. 2;
  • FIG. 4 is an enlarged cross sectional view of FIG. 3C; [0012]
  • FIG. 5 is a schematic view of the striking face of the present invention; [0013]
  • FIG. 6 is a side view of the golf club with the striking face of the present invention; and [0014]
  • FIG. 7 is a plan view of the rear side of another embodiment of the striking face of the present invention.[0015]
  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • With reference to FIG. 1, a golf club ([0016] 1) has a striking face (2) engaging with the golf club (1) at a joint (3).
  • With reference to FIG. 2, the striking face has a rear face ([0017] 20). The rear face (20) is elliptical. A transverse line and a perpendicular line divide the elliptical rear face (20) into four sections with equal areas. Two diagonal lines respectively divide the four sections into eight sections with equal areas, wherein a center of the jointing position (O) of the lines corresponds to the sweet spot.
  • With reference to FIGS. 3A, 3B and [0018] 3C and taking FIG. 4 for a better understanding of the structure of the rear face (20), it is noted that the rear face (20) of the striking face (2) has a maximum thickness, i.e. 3 mm. The joint (3) has a thickness i.e. 2.8 mm. An inner peripheral edge of the joint (3) engaging with the transverse line and the perpendicular line have a thickness the same as that of the joint (3). However the inner peripheral edge of the joint (3) engaging with the diagonal lines has a minimum thickness, i.e. 2 mm. Therefore, with reference to FIGS. 2 and 7, it is noted that the joint position (O) has the maximum thickness, the inner peripheral edge of the joint (3) engaging with the transverse line and the perpendicular line has a medium thickness and the inner peripheral edge of the joint (3) engaging with the diagonal lines has a minimum thickness, which is shown in the embodiment in FIG. 2. Another embodiment is that the joint position (O) has the maximum thickness, the inner peripheral edge of the joint (3) engaging with the diagonal lines has a medium thickness and the inner peripheral edge of the joint (3) engaging with the transverse line and the perpendicular line has a minimum thickness, which is shown in the embodiment in FIG. 7.
  • With reference to FIGS. 5 and 6, when a golfer is striking a golf ball at an area other than the joint position (O), if the area (striking position) is close to the joint position (O), the counter reaction to the golf ball will be the same as that of striking the golf ball with the joint position (O). When striking the golf ball at an area other than the joint position (O) and close to the joint ([0019] 3), because the thickness is decreased, the counter reaction to the golf ball will be the same as that of striking the golf ball with the joint position (O). For example, when the golfer strikes the golf ball with point (P), the point (P) is close to joint position (O) but has a thickness less than that of the joint position (O) so that the counter reaction to the golf ball is the same as that of the joint position (O) to the golfball. When comparing point (Q) and point (R), it is noted that the slope from the joint position (O) to the point (R) is more acute than that of the joint position (O) to the point (Q). Therefore, the effective striking area is within an area enclosed by a half distance from the joint position (O) to the joint (3).
  • It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed. [0020]
