Description

Wood type golf club {WOOD TYPE GOLF CLUB}

The present invention relates to a wood-type golf club, and more particularly, to a wood-type golf club that increases the effective hitting area of the head and lowers the center of gravity of the head to improve the directionality and flying distance of the hit golf ball.

In general, wood-type golf clubs are widely used for shooting long distances. The wood type golf club has a head having a striking surface on which a golf ball is hit. The striking surface of the head is formed to be inclined at a loft angle close to the vertical. The center point of the striking surface, located approximately in the center region of the striking surface, is substantially coincident with the center of gravity, which is the three-dimensional center position of the head.

Therefore, the moment you hit the golf ball by swinging the wood-type golf club, the head is rotated to hit the golf ball, so if the golf ball is not exactly aligned with the center point of the head, that is, the sweet spot, the golf ball is outside, In many cases, they become inside, not fly along their intended trajectory, ie hook or slice.

Therefore, the majority of wood-type golf club users make an effort to move the center of gravity of the head to improve the direction and distance of the hit golf ball to improve the direction and stability of the head as soon as the golf ball hit the head hitting surface Doing.

Accordingly, wood-type golf club users may additionally mount weights on the lower surface of the head, a so-called sole area, or mount a screw bar toward the shaft under the head.

However, in the conventional wood type golf club, since the weight or screw bar are provided at a single position, the sweet spot of the hitting surface of the head, that is, the effective hitting area is narrow, and the weight distribution of the head is difficult to be performed, making it difficult to perform a stable swing. There is a problem.

Accordingly, an object of the present invention is to provide a wood-type golf club that can make a stable swing and improve the direction and flying distance of the golf ball to be hit.

In order to achieve the above object, the present invention, a wood having a head having a front portion having a hitting surface on which a golf ball is hit, and a rear portion which forms a buffer space therein together with the front portion and is coupled to the rear surface of the front portion. In a golf club; It provides a wood-type golf club comprising a pair of weights protruding from the inner wall surface of the rear portion toward the striking surface of the front portion and spaced apart from each other with the center vertical surface of the striking surface interposed therebetween.

Here, the weight is formed in the lower region of the center horizontal plane of the hitting surface, so that the center of gravity of the head is located in the lower region of the center horizontal plane of the hitting surface so that the user can stably swing the golf ball At the moment of hitting, the direction and stability of the golf ball to be hit by the directionality and stability of the head is improved.

Hereinafter, with reference to the accompanying drawings will be described in detail for the subject innovation.

1 is a schematic perspective view of a typical wood golf club. As shown in the drawing, the wood-type golf club 1 includes an elongated shaft 5, a head 10 provided at one end of the shaft 5 and striking a golf ball, and another end of the shaft 5; It is comprised by the grip 7 which a user can hold | grip.

Figure 2 is a schematic enlarged perspective view of the head, Figure 3 is a major cutaway perspective view of the head according to the present invention, Figure 4 is a cross-sectional view taken along line IV-IV of Figure 3, Figure 5 is a line V-V of Figure 4 In accordance with the cross-sectional view. As shown in these figures, the head 10 has a front portion 11 having a striking surface 13 on which a golf ball is hit, and a buffer space 17 formed inside the front portion 11 together with the front portion 11 and the front side thereof. It consists of the rear part 21 couple | bonded with the back surface 11a of the part 11. The front portion 11 and the rear portion 21 of the head 10 have a predetermined thickness.

The striking surface 13 of the front portion 11 is formed flat and has a predetermined loft angle. In addition, the striking surface 13 has a center point 15 of the striking surface 13, which is located at the point where the golf ball fits best, i.e., a sweet spot. And the hitting surface is provided with the groove 13a which forms many concentric circles with respect to the center point 15 as a reference. Thus, when the golf ball is hit at the sweet spot of the striking surface 13 of the head 10 when swinging the wood-type golf club 1, energy is transferred from the head 10 to the golf ball so that the golf ball is intended. Fly along the orbit. Although not shown here, the striking face 13 may be formed with a plurality of horizontal grooves instead of a plurality of concentric grooves 13a.

The rear portion 21 is composed of a rear surface 23, an upper surface 25, a lower surface 27, a toe 29 and a heel 31 on both sides facing the striking surface 13. do. Each surface of the rear portion 21 has a generally smooth curved surface. Each corner formed by each face is also rounded. The upper surface 25 near the heel 31 is provided with a hosel 33 to which one end of the shaft 5 is coupled. The hosel 33 has a receiving hole (not shown) in which the shaft 5 is accommodated, and is installed to be inclined upwardly from the upper surface 25.

Meanwhile, as shown in FIGS. 3 to 5, the rear surface 23 of the rear portion 21 has a predetermined direction from the inner wall surface 23a of the rear surface 23 toward the striking surface 13 of the front portion 11. A pair of weights 35 protruding in width and length are provided. The weights 35 are disposed to be spaced apart from each other with the center vertical plane of the striking face 13 interposed therebetween so that the weight of each weight 35 is evenly distributed based on the center vertical plane of the striking face 13. Each weight 35 is located in the lower region of the center horizontal surface of the striking surface 13. Thus, the effective hitting distance (A in FIG. 5) of the hitting face 13 is widened by the distance that each weight 35 is disposed to be spaced apart from each other with the center vertical plane of the hitting face 13 interposed, that is, the hitting face 13 ) And the center of gravity of the head 10 is lowered by moving the center of gravity of the head 10 to the lower region of the center horizontal plane of the striking surface 13. You lose.

On the other hand, when looking at the process of manufacturing the metal head according to the present invention as an embodiment, a pair of protruding toward the striking surface of the front portion from the inner wall surface of the rear and spaced apart from each other with the center vertical plane of the striking surface therebetween The hollow head which has a weight and the opening part in the lower side is integrally cast by precision casting methods, such as a lost wax. Then, the opening of the head is closed with the lower plate to weld the lower plate along the edge of the opening of the head. Next, the outer surface of the welding bead is ground and polished to complete a metal head.

With this configuration, the head 10 is increased when the user swings the wood-type golf club 1 by widening the effective hitting area of the hitting surface 13 of the head 10 and lowering the position of the center of gravity of the head 10. The moment the hit the golf ball while rotating, the head 10 has the directionality and stability, the user can make a stable swing and the hit golf ball is improved in the direction. In addition, the force applied to the golf ball at the sweet spot consisting of the effective hitting area of the hitting surface 13 of the head 10 is increased to increase the energy transmitted from the head 10 to the golf ball, so that the golf ball may fly away. . That is, while the flying distance of the hit golf ball is improved, the hook or the slice is prevented. And, since the position of the center of gravity of the head 10 is low, the golf ball can be easily floated when hitting the golf ball.

In this way, the pair of weights are disposed at a predetermined interval from the center vertical plane of the striking surface to widen the effective striking area of the striking surface, and move the center of gravity of the head to the lower region of the center horizontal plane of the striking surface, thereby increasing the center of gravity of the head By lowering the position, not only can the swing be stabilized, but also the repulsive force, direction and flying distance of the golf ball being hit can be improved.

In the above-described embodiment, the pair of weights protrude from the inner wall face of the rear face toward the striking face in the lower region of the center horizontal plane of the striking face of the head. Of course, it can project toward.

As described above, according to the present invention, there is provided a wood-type golf club that can make a stable swing and improve the direction and flying distance of the golf ball being hit.
