Brief Patent Description - Full Patent Description - Patent Application Claims
BACKGROUND OF THE INVENTION [0001]1. Field of the Invention [0002]The present invention relates to a golf club head having a complex striking plate structure. Particularly, the present invention relates to the complex striking plate structure of the golf club head formed with multiple metal/nonmetal plates combined together. More particularly, the present invention relates to the complex striking plate structure of the golf club head having elastically deformable spaces provided between two metal/nonmetal plates. [0003]2. Description of the Related Art [0004]A conventional golf club head, as described in Taiwanese Patent Publication No. 550106, entitled "JOINING METHOD FOR GOLF CLUB HEAD," discloses the following steps: [0005]1. Preparing a first metal plate and a second metal plate made from a first metal and a second metal which are heterogeneous metals; [0006]2. Joining the first metal plate and the second metal plate to form a complex metal plate by explosion welding; [0007]3. Shaping the complex metal plate into a first part (i.e. striking plate) of the golf club head having a first peripheral configuration; [0008]4. Removing a central portion (i.e. sweet spot) of the second metal plate from the first part to form a peripheral portion thereof; [0009]5. Preparing a second part (i.e. club head body) of the golf club head having a second peripheral configuration corresponding to the first peripheral configuration of the first part of the golf club head, and the second part made from the second metal; [0010]6. Abutting the first peripheral configuration of the first part against the second peripheral configuration of the second part by arranging the first metal plate of the first part at an outer surface of the golf club head; and [0011]7. Welding the second metal of the first part to the second metal of the second part to form the golf club head. [0012]Although such a striking plate can be successful in providing a high degree of elastic deformability in the central for impacting a golf ball, it can have several disadvantages. A number of design limitations exist for such a striking plate due to (1) difficulties in manufacturing, and (2) problematic aspects which naturally occur during use. The primary problem with the structure of such a striking plate is the difficulty in forming a recessed hole on the second metal plate of the striking plate since it may sophisticate the steps of manufacture, and increase manufacture cost. [0013]With regard to the problematic aspects which naturally occur during use, such a striking plate susceptible to a number of problems, including: (1) loss of the structural strength of the central portion of the striking plate; and (2) weakness of the combined relationship between the two metal plates of the complex striking plate. The primary problem with the structure of such a striking plate is due to the fact that the central portion (i.e. sweet spot) of the striking plate has a relatively thin thickness. Although it would be advantage to make the central portion of the striking plate from thinner material with a higher degree of elastic deformability, the thinner first plate of the striking plate is susceptible to distortion or crack in the central portion, after long-term use, due to a greater stress or impact in repeatedly striking a golf ball. However, the thin central portion of the striking plate has a thickness substantially identical with that of the first metal plate which may weaken the entire strength of the striking plate. [0014]Another problem with the structure of such a striking plate is weakness of the welding portion due to the fact that only the peripheral portion of the second metal plate is combined with the first metal plate. The first metal plate may peel off or fall off from the second metal plate of the striking plate which is connected with the golf club head body after long-term use. This may reduce the useful life of the golf club head. [0015]As is described in greater detail below, the present invention intends to provide a golf club head having a complex striking plate structure including a first plate and a second plate combined together. Elastically deformable spaces are provided between the first plate and the second plate, and one of which is provided with upraised engaging members. The second plate is further combined with a third plate to enhance the elastic deformability of the complex striking plate structure in such a way as to mitigate and overcome the above problem. SUMMARY OF THE INVENTION [0016]The primary objective of this invention is to provide a golf club head having a complex striking plate structure, wherein a first plate and a second plate are combined to form a striking plate. Elastically deformable spaces are formed between the first plate and the second plate so as to provide a high degree of elastic deformability of the striking plate. Accordingly, the complex striking plate structure can enhance the striking stability of the golf club head. [0017]The secondary objective of this invention is to provide the golf club head having the complex striking plate structure, wherein one of the first plate and the second plate provided with upraised engaging members. Each of the elastically deformable spaces can be defined between any two of the adjacent upraised engaging members. Accordingly, the complex striking plate structure provided with the upraised engaging members can enhance the striking stability of the golf club head. [0018]Another objective of this invention is to provide the golf club head having the complex striking plate structure, wherein a first plate, a second plate and a third plate are combined to form a striking plate. A first series of elastically deformable spaces is formed between the first plate and the second plate while a second series of elastically deformable spaces is formed between the second plate and the third plate. Accordingly, the complex striking plate structure provided with two series of elastically deformable spaces further enhances the striking stability of the golf club head. [0019]The golf club head in accordance with an aspect of the present invention includes a golf club head body and a striking plate. The striking plate includes a first plate, a second plate and elastically deformable spaces. The first plate has a front surface to provide a striking surface for impacting a golf ball, and a rear surface to provide a first connecting surface for confronting with the second plate. The second plate has a front surface to provide a second connecting surface for confronting with the first plate, and a rear surface exposed in an inner space of the golf club head body. The first connecting surface of the first plate is attached to the second connecting surface of the second plate to form the striking plate which is connected to a front portion of the golf club head body. The elastically deformable spaces are formed between the first connecting surface of the first plate and the second connecting surface of the second plate. [0020]In a separate aspect of the present invention, one of the first plate and the second plate is provide with upraised engaging members, and each of the elastically deformable spaces is defined between any two of the adjacent upraised engaging members. [0021]In a yet further separate aspect of the present invention, a connecting layer existed between the first plate and the second plate separates any two of the adjacent elastically deformable spaces. [0022]In a yet further separate aspect of the present invention, the upraised engaging member has a tilt to a side. [0023]In a yet further separate aspect of the present invention, any two of the upraised engaging members tilt to opposite sides or toward each other. [0024]In a yet further separate aspect of the present invention, the upraised engaging member includes an upright flat wall and a curved end wall connected thereto. [0025]In a yet further separate aspect of the present invention, each side of the upraised engaging members is formed from an inclined surface having an inclination to the second connecting surface of the second plate. [0026]In a yet further separate aspect of the present invention, any two of the adjacent upraised engaging members define a V-shaped groove extending across the second connecting surface of the second plate. [0027]In a yet further separate aspect of the present invention, the second plate is made from a single sheet formed with a series of square waves.
