Also, the number of the carving projections is increased or decreased toward a desired direction.

Description

Golf club head face with raised protrusions

The present invention aims to drastically improve the function of the golf club by improving the structure of the club face, which is a part of the wood club or the iron club in the golf club head.

Commonly known iron clubs and wood clubs have grooves of various cross-sectional shapes, such as squares or triangles, on the face to prevent slippage when the ball touches the face during swing impact. It has a structure that forms a groove. This structure, in the case of the iron club, serves to stop the on green ball from running without a run and to help back spin.

In addition, when the ball hits the face during swing impact, the groove of the engraving on the face of the club is lost due to slip by increasing the deformation energy of the ball due to contact with the ball during impact and preventing the ball from slipping. By reducing the impact energy is a flying distance increase effect.

In general, the golf club head is deformed instantaneously while hitting the club face surface at the impact of the swing, the golf ball is flatly distorted along the face surface, the golf ball is in close contact with the face surface. At this time, when the golf ball hits the face of the club, the part of the golf ball is deformed along the groove of the face of the face when the golf ball is in close contact with the face, resulting in catching the golf ball and expanding the contact area between the golf ball and the face. It is to reduce the slip of the golf ball, improve the spin function of the golf ball and increase the deformation energy of the golf ball to increase the distance. However, this intaglio structure has a small degree of deformation because the surface of the golf ball must be deformed along the groove of the intaglio, and thus there is a limit to preventing slippage between the face of the head and the golf ball, and the golf ball must be deformed along the groove of the intaglio. As a result, the degree of deformation is limited, and there is a limit to increasing the distance.

Many golfers, however, are dissatisfied with current golf clubs and demand better golf clubs, but the conventional method of digging intaglio grooves on the face has been improved for a long time and is no longer a breakthrough. It is difficult to expect improvement. Therefore, the present invention improves the face surface structure having the grooves of the conventional intaglio to prevent maximum slip between the face surface of the head and the golf ball at impact, greatly improve the spin function of the golf ball and also increase the deformation energy of the golf ball. To suggest a golf club head face structure that can increase the distance.

As a specific means of the present invention for achieving the object of the present invention instead of digging an existing engraving groove (groove) having a square or triangular cross-section on the face of the golf club head embossed having a variety of cross-sectional shape ( By creating carvings, it is possible to overcome the disadvantages of conventional golf club heads having recesses.

Hereinafter, a preferred embodiment of the face surface structure of a golf club head according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a case of embossing a straight protrusion on a wood golf club head face as an embodiment of the present invention, Figure 2 is a perspective view of an iron golf club head embossed a straight protrusion on the face of the present invention.

3 is a cross-sectional view of a modified form of the embossed protrusions of FIGS. 1 and 2, wherein (a) shows that the protrusions have a rectangular shape, (b) shows that the protrusions have a circular shape, and (C) shows a trapezoidal shape. Indicates.

4, 5, and 6 show a golf club head in which local pillar protrusions, rather than straight reliefs, are distributed over the entire head face area as another embodiment of the invention. 4 (a) and 4 (b) are front and AA sectional views of the golf club head face when the protrusions are rectangular, and FIGS. 5 (a) and 5 (b) are front views of the golf club head face when the protrusions are circular. 6B and 6B are front and CC cross-sectional views of the golf club head face in the case where the protrusion is trapezoidal.

The wood golf club head to which the present invention is applied as shown in FIG. 1 is composed of a neck 1 into which a club shaft is inserted, a sole 2 forming a bottom surface, and a crown 3 and a face 4 forming an upper surface. The face 4 is embossed with a straight protrusion p. In addition, the iron (iron) golf club head to which the present invention is applied, the neck (1) and the sole (2) is formed on the bottom and the top edge (5) and the face (4) is formed on the bottom of the club shaft is inserted as shown in FIG. It consists of. The face 4 is embossed with a straight protrusion p.

The protrusions formed on the face of the wood golf club head and the iron golf club head may have a straight quadrangular shape, such as the protrusion shapes of FIGS. 1 and 2, and may be circular or trapezoidal rather than rectangular as shown in FIG. It may have a shape of.

The protrusions formed on the face of the wood golf club head and the iron golf club head are not only straight as shown in FIGS. 1 to 3 but also at regular intervals on the face 4 as shown in FIGS. 4 to 6. It may have a variety of embossed pillar protrusions having a cross section of a square, trapezoid, hemispherical shape and the like of a certain size. Also, the embossed pillar protrusions shown in FIGS. 4 to 5 may be distributed at regular intervals and may be distributed with a specific ratio in any direction with a specific ratio in column size and spacing. It is possible.

When the projection is formed in the embossed rather than intaglio as in the present invention, when the golf ball hits the golf club head face during swing impact, the golf ball is deformed along the embossed protrusion of the face to catch the golf ball as compared to the case of the conventional intaglio grooves. Its role is to improve the contact area between the face and the golf ball, and to prevent the golf ball from slipping to the maximum, and to greatly improve the spin function of the golf ball. The amount of deformation of the ball is increased to increase the deformation energy of the golf ball to act to increase the distance.

In the above, a preferred embodiment according to the present invention has been described, but the present invention is not limited thereto, and various modifications and changes can be made within the scope of the claims and the detailed description of the invention and the accompanying drawings. It can belong to.

Golf club according to the present invention having the configuration as described above can prevent the slip of the golf ball during the swing impact and increase the spin of the golf ball to greatly improve the difficulty of the golf ball and the direction of the spin ball not only stable golf shot is possible In addition, by increasing the deformation energy of the golf ball to increase the elastic energy of the golf ball has the effect of increasing the distance.
