Golf club head
Disclosed is a golf club head including a faceplate portion and a main body constituting a remaining part of the golf club head. A plurality of linear protrusions formed parallel to one another on the rear surface (opposing to the front striking surface) of the faceplate portion. The linear protrusions have different lengths and are arranged in an elliptical pattern or a diamond pattern covering the vertical projection of the center-of-gravity of the golf club head on the rear surface of the faceplate portion.

This invention relates to wood or iron type golf club heads.
BACKGROUND OF THE INVENTIONVarious improvements are applied to a golf club head in order to increase a striking distance that a stable strike can achieve. Particularly, the striking distance directly influences the score. In order to obtain a maximum striking distance, golfers usually have to hit the ball on the sweet area of golf club head. However, it is difficult for many amateur players to hit the ball on the sweet area.
There has been developed golf clubs having an enlarged dimension of the driver head thereby obtaining an enlarged sweet area so as to realize an easy strike. However, the sweet area is inevitably moved upward since the center of gravity is shifted to the upper side due to the enlarged dimension of the head. This contradicts the requirement for lowering the center of gravity of the golf club head.
Therefore, there is still room for improvement of golf club heads, particularly in terms of enlarging the sweet area.
SUMMARY OF THE INVENTIONTherefore, it is an object of the present invention to provide a golf club head having enlarged sweet area thereby resulting in less missing shots.
An iron type or wood type golf club head having features of the present invention generally comprises a faceplate portion and a main body. The faceplate portion has a front striking surface for striking a golf ball and a rear surface opposing to the front striking surface. The main body includes a top portion forming an upper part of the golf club head, a sole portion forming a lower part of the golf club head, a toe portion forming a forepart of the golf club head; a heel portion forming a rear part of the golf club head; and a hosel portion adapted to be fastened to a shaft.
To achieve the above listed and other objects, a plurality of linear protrusions are formed parallel to one another on the rear surface of the faceplate portion and located among the top portion, the sole portion, the toe portion, the heel portion, and the hosel portion, thereby having an enlarged sweet area so as to realize an easy strike. The linear protrusions have different lengths and are arranged in an elliptical pattern or a diamond pattern covering the vertical projection of the center-of-gravity of the golf club head on the rear surface.
Preferably, the geometrical center of the elliptical pattern or the diamond pattern is substantially located at the vertical projection of the center-of-gravity of the golf club head on the rear surface of the faceplate portion.
The golf club heads of the present invention have a larger sweet area which is realized by providing the linear protrusions on the rear surface of the faceplate portion thereof. By expanding the sweet area, it becomes easier for many amateur players to hit the ball on the sweet area.
BRIEF DESCRIPTION OF THE DRAWINGSOther objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawing:
While the present invention is susceptible of embodiment in various forms, there are presently preferred embodiments shown in the drawings and will hereinafter be described with the understanding that the present disclosure is to be considered as an exemplification of the invention and is not intended to limit the invention to the specific embodiment illustrated.
Now, embodiments of the present invention are described with reference to the drawings.
The main body 120 includes a top portion 122 forming an upper part of the golf club head, a sole portion 123 forming a lower part of the golf club head, a toe portion 124 forming a forepart of the golf club head; a heel portion 126 forming a rear part of the golf club head; and a hosel portion 128 adapted to be fastened to a shaft (not shown). The top portion 122 may have a recess or cavity in the back thereof.
The faceplate portion 110 has a front striking surface 110a for striking a golf ball and a rear surface 110b opposing to the front striking surface. As shown in
As shown in
Preferably, the geometrical center of the elliptical pattern or the diamond pattern is substantially located at the vertical projection of the center-of-gravity 130 of the golf club head on the rear surface 110b of the faceplate portion.
In one embodiment of the present invention, the sole portion 123 may have an opening (not shown) formed in the lower corner edge thereof, and an insert is fitted into and joined to the opening. The insert has the same contours as that of the opening and is made of a material with a larger specific gravity than that of the material of the sole portion 123. With this arrangement, the center-of-gravity of the head shifts rearward in relation to the mounting position of the insert 6. Accordingly, it is possible to further deepen and lower the center-of-gravity of the iron club head.
The golf club heads of the present invention have a larger sweet area which is realized by providing the linear protrusions on the rear surface of the faceplate portion thereof. By expanding the sweet area, it becomes easier for many amateur players to hit the ball on the sweet area.
As is understood by a person skilled in the art, the foregoing preferred embodiments of the present invention are illustrated of the present invention rather than limiting of the present invention. It is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims, the scope of which should be accorded the broadest interpretation so as to encompass all such modifications and similar structure.
