Description
- 1. Field of the Invention
- The present invention generally relates to a golf club head and a fabricating method thereof. More particularly, the present invention relates to a golf club head with a striking plate having cavities to improve the striking effect and a fabricating method of the striking plate.
- 2. Description of Related Art
- Sports are becoming more and more popular, and golf has already become one of the most widely enjoyed sports. In addition, the number of participants in the sport of golf has risen rapidly. In which, the golf club used for playing golf, because of the varieties in purposes and course geographies, are categorized into different types such as wood club, iron club, and putter.
- With respect to the wood club, the golf club head typically comprises a shell and a striking plate on the shell for use to strike the ball. When the golf club head strikes a golf ball, the striking plate receives a large impact and produces a reacting force to the golf ball, and thus the golf ball obtains the kinetic energy transferred from the reacting force for a long distance flight.
- However, due to the intrinsic properties of material or the structure design of a conventional golf club, the preferred striking region of the golf club may be restricted and even goes aberrant.
FIG. 1 illustrates the striking surface of a conventional striking plate, in which an aberration of preferred striking region is observed. As shown in FIG. 1, the striking plate is divided into four portions by a two-dimensional coordinate, wherein the origin of the two-dimensional coordinate is located at thegeometric center 100 a of thestriking surface 100. The X-axis and Y-axis of the two-dimensional coordinate defines afirst quadrant 102 between theheel 112 and thecrown 114 of the golf club head, asecond quadrant 104 between thecrown 114 and thetoe 116 of the golf club head, athird quadrant 106 between thetoe 116 and the sole 118 of the golf club head, and afourth quadrant 108 between the sole 118 and theheel 112 of the golf club head. - After dividing the striking surface into four quadrant, and project the center of gravity of the golf club head onto this surface, this center of gravity would have a projected location at 120, within the
first quadrant 102 of the striking surface. Herein, the projected center ofgravity 120 is the ideal striking point (sweet spot) where the golf ball would receive the maximum reacting force by the impact from the striking plate. Furthermore, if we record the coefficient of reaction around the projected center ofgravity 120, we find that the coefficient of reaction decrease outward from the projected center ofgravity 120. Generally, the projected center ofgravity 120 of the golf club head is located in thefirst quadrant 102 between theheel 112 and thecrown 114 of the golf club head. If the location where the golf ball impacts the striking plate is far away from the projected center ofgravity 120, a torque caused by component force related to the projected center ofgravity 120 will be produced, and the reacting force applied to the golf ball is diminished. - Specifically, as shown in
FIG. 1 , a preferredstriking region 130 can be defined on thestriking surface 100, which refers to the region where an acceptable and better striking effect can be achieved as the golf ball impacts the striking plate. However, most of the preferredstriking region 130 is situated in thefirst quadrant 102 between theheel 112 and thecrown 114 of the golf club head due to the projected center ofgravity 120 located off center. In other words, a powerless strike or even an unexpected fault may occur if striking the golf ball out of the preferredstriking region 130 on thestriking surface 100. Thus, for enlarging the forgiveness of striking, we have to enhance the reaction force of the striking surface other than the first quadrant. - Accordingly, the purpose of the present invention is to provide a golf club head having a preferred striking region by a modification to the thickness of the striking plate thereof.
- The purpose of the present invention is to provide a method for fabricating the striking plate mentioned above.
- Based on the aforementioned and other purposes, the present invention proposes a golf club head, which includes a shell and a striking plate. The shell has an opening and the striking plate is disposed at the opening. In addition, the striking plate has a striking surface and at least one cavity is formed on the striking plate opposite to the striking surface for modifying a preferred striking region of the golf club head.
- In an embodiment of the present invention, the projected center of gravity of the golf club head is located in a first quadrant defined by a two-dimensional coordinate having an origin located at the geometric center of the striking surface, and at least one portion of the striking plate in a second quadrant, a third quadrant and a fourth quadrant defined by the two-dimensional coordinate has a cavity opposite to the striking surface.
- In an embodiment of the present invention, the thickness of the portion of the striking plate having the cavity is between 0.5 mm and 3 mm.
- In an embodiment of the present invention, the profile of the cavity is regular.
- The present invention also proposes a method for fabricating the aforementioned striking plate of the golf club head. The fabricating method includes providing a work piece and forming the striking plate with the cavity from the work piece.
- In an embodiment of the present invention, the cavity is integrally formed with the striking plate. In which, the striking plate with the cavity may be formed by pressing, casting, or forging.
- In an embodiment of the present invention, the cavity is formed by performing an extra work to the work piece. In which, the cavity may be formed by mechanical or chemical milling.
- Based on the above, the striking region of the golf club head can be modified by forming at least one cavity on the striking plate opposite to the striking surface. By the modification of the preferred striking region, the striking effect of the golf club head can be promoted so as to increase the flight distance of the golf ball and improve the ball striking accuracy.

In addition, theshell 210 has anopening 210 a, and thestriking plate 220 is disposed at the opening 210 a. - The present invention may use welding for bonding the
shell 210 and thestriking plate 220. After theshell 210 and thestriking plate 220 are engaged, further welding is conducted for binding theshell 210 and thestriking plate 220. - Otherwise, the
shell 210 can further be first engaged with thestriking plate 220, and then the bonding agent is spread at the seam of the bonding location between theshell 210 and thestriking plate 220. After the bonding agent has melted and seeped into the bonding surface, further cooling and solidifying to forming a bonding layer (not shown) between theshell 210 and thestriking plate 220. - In the present invention, at least one cavity is formed on the
striking plate 220 opposite to thestriking surface 300 in order to modify the preferred striking region of thegolf club head 200.FIG. 3A shows theback surface 400 of thestriking plate 220 as shown inFIG. 2 according to an embodiment of the present invention.FIG. 3B shows a front view of thegolf club head 200. Referring toFIGS. 3A and 3B , theregion 332 refers to the original preferred striking region of thestriking plate 220. After forming thecavities 222 at two opposite sides of the original preferredstriking region 332 on theback surface 400, the original preferredstriking region 332 extends mainly in two opposite directions corresponding to the location of thecavities 222 and thus is enlarged into a new preferredstriking region 332 a. - Similarly, referring to
FIGS. 4A and 4B , which further illustrate theback surface 400 of thestriking plate 220 and the front view of thegolf club head 200 according to yet another embodiment of the present invention. As shown inFIGS. 4A and 4B , fourcavities 222 are formed surrounding the original preferredstriking region 332 on theback surface 400, and the original preferredstriking region 332 is enlarged into the preferredstriking region 332 a with thecavities 222. - According to the aforementioned embodiments, the thickness of the striking plate is reduced by forming cavities on the back surface of the striking plate. In general, a thinner portion of the striking plate has higher coefficient of reaction than that of other portions of the striking plate. Therefore, the preferred striking region of the golf club head can be enlarged by forming cavities on the back surface of the striking plate.
- In other scope, the present invention can also be conducted for solving the aberration of the preferred striking region.
FIG. 5 illustrates thestriking surface 300 of thestriking plate 220 as shown inFIG. 2 according to yet another embodiment of the present invention. Referring toFIGS. 2 and 5 , thestriking plate 220 can be divided by a two-dimensional coordinate, wherein the origin of the two-dimensional coordinate is located at the geometric center 300 a of thestriking surface 300. On thestriking surface 300, afirst quadrant 302 between theheel 312 and thecrown 314 of the golf club head, asecond quadrant 304 between thecrown 314 and thetoe 316 of the golf club head, athird quadrant 306 between thetoe 316 and the sole 318 of the golf club head, and afourth quadrant 308 between the sole 318 and theheel 312 of the golf club head are respectively defined by the X-axis and Y-axis of the two-dimensional coordinate. - Referring to
FIGS. 2 and 5 again, the projected center ofgravity 320 of thegolf club head 200, which refers to the ideal striking point on thestriking surface 300, is located in thefirst quadrant 302 due to the structural design and the necessity for connecting with a rod (not show) to form a golf club (not show). It should be noted that in order to prevent the torque caused by component force related to the projected center ofgravity 320 and to enlarge the preferred striking region on thestriking surface 300, the presentinvention forms cavities 222 on theback surface 400 of thestriking plate 220 respectively in thesecond quadrant 304, thethird quadrant 306 and thefourth quadrant 308. - Referring again to
FIGS. 2 and 5 , theregion 332 refers to the original preferred striking region of thestriking plate 220 before forming thecavities 222, andnew regions second quadrant 304, thethird quadrant 306, and thefourth quadrant 308 are obtained after thecavities 222 are formed. That is to say a larger preferred striking region comprising theregions striking surface 300 is acquired to provide an acceptable and better striking effect as the golf ball impacts thestriking plate 200. Therefore, the powerless strike or even the unexpected fault can be effectively prevented and thus the striking effect is improved. - Based on all the above embodiments, a preferred thickness of the portions of the
striking plate 220 having thecavities 222 is between 0.5 mm and 3 mm, moreover, in the embodiments the profile of thecavities 222 is regular, such as circle. However, in other embodiments of the present invention the profile of the cavities can further be irregular. - Specifically, the method for fabricating the
striking plate 220 of thegolf club head 200 may first provide a work piece and then form thestriking plate 220 with thecavities 222 from the work piece. For example, thecavities 222 can be integrally formed with thestriking plate 220, wherein thecavities 222 may be formed by punching, casting, or forging. Otherwise, thecavities 222 can further be formed by performing an extra work such as mechanical or chemical milling to the work piece. - It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. For example, regarding to achieve an improvement in specific regions of the striking surface or to meet some particular design requirements, the cavity or cavities may be formed in any specific location on the back surface of the striking plate. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
