Description

  The present invention relates generally to golf club heads. More particularly, the present invention relates to a golf club head comprising a striking plate having a cavity in order to improve the striking effect.

  Sport is becoming increasingly popular and golf has already become one of the most widely enjoyed sports. Furthermore, the number of people who like golf is increasing rapidly. In golf, since the purpose and course terrain vary, golf clubs used for golfing are classified into various types such as wood clubs, iron clubs, and putters.

  With respect to wood clubs, golf club heads typically include an outer shell and a striking plate on the outer shell for hitting the ball. When the golf club head hits the golf ball, the striking plate receives a large impact and generates a reaction force against the golf ball. Therefore, the golf ball obtains kinetic energy transmitted from the reaction force and extends the flight distance.

  However, due to the inherent properties or structural design of conventional golf club materials, the preferred striking area of a golf club is limited and may even go aberrant. FIG. 1 shows a striking surface of a conventional striking plate in which the preferred striking region is misaligned. As shown in FIG. 1, the striking plate is divided into four parts by two-dimensional coordinates, and the origin of the two-dimensional coordinates is at the geometric center 100 a of the striking surface 100. The X and Y axes of the two-dimensional coordinates are the first quadrant 102 between the heel 112 and the crown 114 of the golf club head, the second quadrant 104 between the crown 114 and the toe 116 of the golf club head, and the golf club head. A third quadrant 106 between the toe 116 and the sole 118 and a fourth quadrant 108 between the golf club head sole 118 and the heel 112.

  If the center of gravity of the golf club head is projected onto this surface after dividing the striking surface into four quadrants, this center of gravity will have a projected position at 120 in the first quadrant 102 of the striking surface. In this specification, the projected center of gravity 120 is an ideal hitting point (sweet spot) at which the golf ball will receive the maximum reaction force due to the impact from the hitting plate. Furthermore, it can be seen that when a reaction force coefficient (coefficient of reaction) is recorded near the projected center of gravity 120, the reaction force coefficient decreases from the projected center of gravity 120 toward the outside. Generally, the projected center of gravity 120 of the golf club head is in the first quadrant 102 between the heel 112 and crown 114 of the golf club head. When the place where the golf ball collides with the striking plate is away from the projected center of gravity 120, torque generated by the component force related to the projected center of gravity 120 is generated, and the reaction force applied to the golf ball is reduced.

  Specifically, as shown in FIG. 1, a preferred striking area 130 can be defined on the striking surface 100, which provides a better striking effect that can be satisfied when a golf ball strikes a striking plate. Refers to the area that can be obtained. However, because the projected center of gravity 120 is off-center, the majority of the preferred striking area 130 is located in the first quadrant 102 between the heel 112 and crown 114 of the golf club head. In other words, hitting a golf ball out of the preferred striking area 130 of the striking surface 100 can result in a forceless hit or even unexpected failure. Therefore, in order to expand the permissible range of hitting, the reaction force of the hitting surface other than the first quadrant must be increased.

  Accordingly, it is an object of the present invention to provide a golf club head having a preferred striking area by changing the thickness of the striking plate.

  Moreover, it is providing the above-mentioned striking plate.

  Based on the above and other objects, the present invention proposes a golf club head that includes an outer shell and a striking plate. The outer shell has an opening, and the striking plate is disposed in the opening. Further, the striking plate has a striking surface, and at least one cavity is formed on the opposite side of the striking surface of the striking plate to alter the preferred striking area of the golf club head.

  In one embodiment of the present invention, the projected center of gravity of the golf club head is in the first quadrant defined by two-dimensional coordinates with the origin at the geometric center of the striking surface, and the second quadrant, third quadrant of the striking plate. , And at least a portion of the fourth quadrant has a cavity on the opposite side of the striking surface.

  In one embodiment of the present invention, the thickness of the portion having the cavity in the striking plate is 0.5 mm to 3 mm.

  In one embodiment of the present invention, the cavity contour is regular.

  In one embodiment of the present invention, the cavity is integrally formed with the striking plate. In this case, the striking plate having the cavity can be formed by pressing, casting, or forging.

  In one embodiment of the invention, the cavity is formed by subjecting the workpiece to additional machining. In this case, the cavity can be formed by mechanical milling or chemical milling.

  Based on the above, the striking area of the golf club head can be changed by forming at least one cavity on the opposite side of the striking surface of the striking plate. By changing the hitting area, it is possible to improve the hitting effect of the golf club head so as to increase the flight distance of the golf ball and improve the hitting accuracy.

  The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the present invention and together with the description text serve to explain the principles of the present invention.

  Reference will now be made in detail to the presently preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.

  FIG. 2 is a three-dimensional exploded view showing the golf club head of the present invention. As shown in FIG. 2, the golf club head 200 has a club head body 202 that includes an outer shell 210 and a striking plate 220 having a striking surface 300 and a back surface 400 on the opposite side. In this embodiment, the outer shell 210 and the striking plate 220 can be made from typical metallic materials such as, for example, carbon fiber or stainless steel or other metallic material. Further, the outer shell 210 has an opening 210a, and the striking plate 220 is disposed in the opening 210a.

  The present invention can use welding to join the outer shell 210 and the striking plate 220. After the outer shell 210 and the striking plate 220 are engaged, further welding is performed to join the outer shell 210 and the striking plate 220.

  Alternatively, the outer shell 210 can further be engaged with the striking plate 220 first, and then spread the adhesive at the joint location seam between the outer shell 210 and the striking plate 220. After the adhesive melts and soaks into the joint surface, it is further cooled and solidified to form a joint layer (not shown) between the outer shell 210 and the striking plate 220.

  In the present invention, at least one cavity is formed on the opposite side of the striking surface 300 of the striking plate 220 to change the preferred striking area of the golf club head 200. FIG. 3A shows the back surface 400 of the striking plate 220 shown in FIG. 2 according to an embodiment of the present invention. FIG. 3B shows a front view of the golf club head 200. With reference to FIGS. 3A and 3B, region 332 refers to the original preferred striking region of striking plate 220. After forming the cavity 222 on the two opposite sides of the original preferred strike area 332 of the back surface 400, the original preferred strike area 332 extends primarily in two opposite directions corresponding to the location of the cavity 222, It is expanded to a new preferred striking area 332a.

  Similarly, referring to FIGS. 4A and 4B, these further illustrate a back surface 400 of a striking plate 220 of a golf club head 200 and a front view of the golf club head 200 according to yet another embodiment of the present invention. As shown in FIGS. 4A and 4B, four cavities 222 are formed around the original preferred strike area 332 of the back surface 400, and the original preferred strike area 332 is expanded by the cavity 222 into the preferred strike area 332a. .

  According to the embodiment described above, the thickness of the striking plate is reduced by forming a cavity on the back surface of the striking plate. In general, the thin portion of the striking plate has a higher reaction force coefficient than the other portions of the striking plate. Accordingly, the preferred striking area of the golf club head can be enlarged by forming a cavity in the back surface of the striking plate.

  In other respects, the present invention can also be carried out to resolve the preferred strike area misalignment. FIG. 5 shows a striking surface 300 of the striking plate 220 shown in FIG. 2 according to still another embodiment of the present invention. 2 and 5, the striking plate 220 can be divided by two-dimensional coordinates, and the origin of the two-dimensional coordinates is at the geometric center 300 a of the striking surface 300.

A third quadrant 306 between 318 and a fourth quadrant 308 between the golf club head sole 318 and the heel 312 is defined by the X and Y axes of two-dimensional coordinates, respectively.

  Referring again to FIGS. 2 and 5, the projected centroid 320 of the golf club head 200 pointing to the ideal strike point on the strike surface 300 is a rod (not shown) to form a golf club (not shown). In the first quadrant 302, the structural design and necessity for connecting to the first quadrant 302. In order to prevent the torque caused by the component force related to the projected center of gravity 320 and to enlarge the preferred striking area of the striking surface 300, the present invention provides a second quadrant 304, a third quadrant 306, and a second quadrant of the rear surface 400 of the striking plate 220. Note that a cavity 222 is formed in each of the four quadrants 308.

  Referring back to FIGS. 2 and 5, region 332 refers to the original preferred striking region of striking plate 220 prior to formation of cavity 222, and after formation of cavity 222, second quadrant 304, third quadrant 306, and second New regions 334, 336, and 338 with a majority in the four quadrant 308 are obtained. That is, it is possible to obtain a larger preferred striking area that includes the areas 332, 334, 336, and 338 and occupies most of the striking surface 300, which is more satisfactory when the golf ball collides with the striking plate 200. A striking effect is given. Therefore, a hitting effect is improved because even a forceless hit or even an unexpected failure can be effectively prevented.

  Based on all the above embodiments, the preferred thickness of the portion of the striking plate 220 having the cavity 222 is between 0.5 mm and 3 mm, and in these embodiments, the contour of the cavity 222 is a rule such as a circle. Is something. However, in other embodiments of the present invention, the contour of the cavity may be more irregular.
