Benefits of technology
"The present invention aims to provide an improved golf club head by reducing the weight of the upper side and creating a crisp sound when hitting the golf ball. This is achieved by integrating a balance weight into the club head and bonding it onto an upper lid made from a composite material or fibers. The balance weight is located in a recess in the club head and covered by the upper lid, which matches the curvature of the club head. The upper lid is made from a composite material or fibers that match the shape of the club head. The foregoing and other objects, features, and advantages of the invention will be more readily apparent from the following detailed description."
Problems solved by technology
Such types of heads often are heavier and move the gravity center forwards and make swinging of golf club more difficult.
But these types of heads have difficulty to lower the gravity center.
As a result, striking stability is difficult to improve.
Such an approach makes the head heavier and swinging of the golf club more difficult.
Hence a small deviation of swinging could result in loss of the standard hitting point and miss the sweet spot.
Such a structure is difficult to fabricate.
It is costly and not very practical.
In short, the present club heads generally are difficult to reduce the weight and results difficulty in swinging of the golf club.
The appearance of the club head is plain and not versatile.
It also cannot generate a crisp sound when the golf ball is hit.

Embodiment Construction
[0020] Please refer to FIG. 1, the golf club head according to the invention includes: [0021] a body 1 made from titanium by forging in an integrated manner. It has a neck 10 on a lateral side with an insert hole 100 to couple with a shaft 4. The body 1 has a hitting face 11 on the front side and a recess 13 formed on an upper side 12 at the rear end. The recess 13 holds a balance weight 2 which is 2b and 2c have respectively apertures 20b of the same size or apertures 21c of different sizes formed thereon.
[0022] Refer to FIGS. 6 and 7 for yet another two embodiments of the present invention. It is constructed substantially like the embodiment shown in FIG. 1. However, the balance weights 2d and 2e have respectively elongated troughs 20d and arched troughs 20e formed thereon.
[0023] Refer to FIGS. 8 and 9 for still another two embodiments of the present invention. It is constructed substantially like the embodiment shown in FIG. 1. However, the balance weights 2f and 2g have respec...

An improved golf club head includes a body, a balance weight and an upper lid. The body has a hitting surface and a recess formed on an upper side of the rear end thereof. The balance weight is located in the recess. The upper lid is made from a composite material or fibers and has a curvature matching the upper side of the golf club head to anchor the balance weight in an integrated manner. Thus the weight of the upper side of golf club head is reduced. The upper lid makes the club head more appealing and can generate a crispy sound when hitting golf ball. A higher trajectory track may be generated when the golf ball is hit. And more versatile appearances may be formed.
Description
FIELD OF THE INVENTION [0001] The present invention relates to an improved golf club head and particularly to a golf club head that has a reduced weight on the upper side, forms a higher trajectory track for the hitting golf ball, is easier to strike, looks more appealing and provides more versatile appearances, and generates a crispy sound when the golf ball is hit. BACKGROUND OF THE INVENTION [0002] With increasingly rising of people's living standard, golf population also grows continuously. Playing golf has to use various types and numbers of golf club heads. The golf ball trajectory track is a big concern for golfers. Many golf club heads are made in an integrated manner. Such types of heads often are heavier and move the gravity center forwards and make swinging of golf club more difficult. These days some golf club heads are made with a hitting panel of a smaller weight. But these types of heads have difficulty to lower the gravity center. As a result, striking stability is d...
