Abstract

An improved structure of a golf club head wherein the head is hollow and has an egg-shaped body. The bottom and top face of the head of the club are circular and arch-shaped. In combination with the bottom and top face forming the circular arch-shaped impact face, the impact face is focused on the center arc line of a horizontal axis of the head. The impact face is reduced and therefore, the wind resistance in the course of swinging the club is also reduced. In addition, the bottom face of the head touching the ground and the resistance in the course of swinging is reduced. Accordingly, the impact of the hitting of the ball is consistent and the rate of successful impact is increased. The head can particularly be a wood, fig 5, or a putter, fig 6.

Description

TITLE: STRUCTURE OF A GOLF CLUB HEAD

BACKGROUND OF THE INVENTION

(a) Technical Field of the Invention

The present invention relates to an improved structure of a golf club head, and in particular, the club head being a hollow egg-shaped body such that the impact face is on a line and the wind resistance in the course of swinging is reduced and the opportunity of the bottom face of the club head touching the ground and resistance is greatly reduced and the stability and rate of success in ball impact is increased

(b) Description ofthe Prior Art

Players in a golftournament pay particular attention to the selection and replacement of clubs. In order to have a good game, a #I club or #3 wooden club is initially used to hit the ball a long, straight distance, and a wooden club or an iron club is then used to hit the ball to the putting green. Lastly, a putter is used to push the ball into the hole.

The head of the club in a wooden club, iron club or putter is larger in size, and the center of gravity is to be found at the larger impact face of the club head. However, there are restrictions on the size ofthe golfclub headwhich have imposed by professional golf associations.

When hitting the ball, the wooden club is lifted upward and is swung downward, and this acceleration prior to hitting the ball can enable the ball to be hit accurately so that it flies in a straight direction. Naturally, there are skills in hitting the ball. In the above swinging of the club, due to the size of the club head and the widening of the impact face, the wind resistance coefficient increases, and the downward swing will further increase this resistance. As a result, the club head will not be able to move simultaneously with the club. Thus, when the impact face of the club head 1 hits a ball as shown in FIG 1, the ball cannot be hit at the sweet spot 12. Theoretically, the larger the impact face, the larger the sweet spot region. However, to hit a high and straight ball, this can only be done by hitting the one sweet spot 12.

If the sweet spot 12 is not hit, the ball will fly to the side, rather than in a straight direction. Due to the large area ofthe impact face and the size of the club head, the impact of the golfball hitting the sweet spot region will not be perfect. The excessive area and size is therefore a hindrance to the golfer.

Further, the golfer's excessive force and the movement of the body may cause the lower end of the impact face 13 to touch the ground, as shown in FIG 2, so that the impact force is diminished The remaining force can only enable the ball to be hit a short distance, especially when a large club head is used The increased size of the impact face and accurate swinging motion makes hitting the ball well difficult to accomplish and it is quite common for the club head to touch the ground. Due to the fact that the size of the club head is large, the golfer often hits the ball with excessive force and the hit is a failure. Therefore, the large size club head will not produce accurate hitting of the ball.

When using the putter 3, as shown in FIG 3, the center of the impact face faces the hole on the putting green, and this will enable the ball to be hit in an accurate direction. Even if the club head of the putter is large, the impact face is wide, and in order to hit the ball in an accurate direction, the point of impact must occur at the sweet spot and the center line of the ball. Thus, the increase in size ofthe club head provides no benefits.

In view of the above, for the club head of any golf club, the accuracy of a ball being hit is based on whether or not the sweet spot of the club head is hit, and not the size of the club head or the widening of the impact face. In other words, the hitting of the sweet spot of the impact face will provide accurate hitting direction. For example, when the impact face is wide as a result ofthe increase of size of the chub head, the impact face, as shown in FIG 1, is slightly arch-shaped. Thus the center point of the archshaped face has to align with the center point ofthe ball. The experienced golfer understands that if the ball is not hit at the center point of impact the ball will fly to the led or right of the fairway. In accordance with the present invention, it is an object to provide an improved structure of a chub head so as to increase the stability of hitting the ball.

SUMMARY OF THE INVENTION

Accordingly, it is an object of the present invention to provide an improved structure of a club head haying a hollow egg-shaped body, wherein the impact face is reduced and the alignment on the sweet spot of impact is improved Yet another object of the present inversion to provide an improved structure of a club head having a hollow egg-shaped body, wherein the impact face is reduced and the errors due to the touching of the impact face ofthe club head during impact with the ground are reduced Yet a further object of the present invention is to provide unimproved structure of a club head wherein the club head is a hollow egg-shaped body such that the coefficient of wind in the course of impact is reduced and the lowering ofthe club head and the displacement ofthe club head are in accord, achieving the impact of the sweet spot by the ball.

The foregoing object and summary provide only a briefintroduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be readin conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.

Many other advantages and features ofthe present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheen of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration ofthe invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments ofthe invention.

Various changes to the described embodiments may be made in the function and arrangement ofthe elements described without departing from the scope of the invention as set forth in the appended claims.

Referring to FIG. 4, there is shown a preferred embodiment of a wooden club. The shape of the club head4 is an egg-shaped structure and a larger end of the club head 4 is protruded upward to connect with the neck portion 41 of a connection shaft 5. This larger diameter end 42 is tapered along the longer axis to the other end portion 43. Thus, the impact face 44 of the club head 4 forms a center line along the longer axis ofthe club head, or an arch-shaped line. The impact face of the arch-shaped line is extended upward, downward, left and right side. The curvature of the impact face 44 has a larger angle as compared with the conventional impact face. The sweet spot 45 is the intersection of the extension line of the shorter shaft of the larger diameter ofthe egg shaped body and the center line ofthe longer shah ofthe egg-shaped body. The region ofthe sweet spot 45 is small but the area ofthe sweet spot is the same size as that ofthe conventional wooden club. Thus, when the club head 4 is used to hit a ball, the sweet spot 45 hits the ball, as shown in FIG. 5, and a high, lengthy hit of the ball will result. If the sweet spot does not hit the ball, the ball will fly to the side.

When the club head 4 of the present invention is used to hit a ball, as shown in FIG. 5, as the extension ofthe top, bottom, left and right side ofthe sweet spot 45 is an arch-shaped face, the wind resistance in hitting the ball using the club head 4 is reduced to a minimum. When the swinging speed and the displacement ofthe club head are synchronized, the impact face ofthe club head can easily hit the center line of sweet spot, thus, the ball is hit accurately and flies straight and far.

The impact face 44 of the club head consists of an arch-shaped line, and the impact face 44 is extended upward, downward, to the left and right sides at a curved angle to form a circular archshape face. Thus, the bottom side 46 of the club head is in contact with the ground. When the golfer swings the club, the impact face 44 will not contact the ground. Even when a great force is used, and the bottom side 46 of the club head touches the ground the ball will roll on the ground and the impact face will still hit the golfball and the hitting distance will not be shortened.

In accordance with the present invention, the neck portion 41 ofthe club head 4 has a larger diameter end being protruded upward. Thus, the weight center ofthe club head4 is closer to the shaft 5, as shown in FIG. 4. When the golfer swings the club, the acceleration ofthe club head can tee increased and vibration or biasing will not occur and the sweet spot 45 will hit the ball more accurately.

If the neckportion 41 has a smaller diameter when connecting to the club head 4, the reduction of the wind coefficient can be attained As shown in FIG 6, when a putter 6 is used, the diameter ofthe ball is equal to or smeller then a common putter. The neck portion 61 is upright and the shaft 5 is at the middle of the club head As shown in FIG 7, when the putter is used to push the ball into the hole, the sweet spot 63 of the impact face 62 is at the intersection of the extension lines of the long shaft towards the center line and the larger diameter region.

It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.

While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spins of the present invention.
