DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf club, and more particularly to a golf club represented by a golf putter, a sand wedge, an iron, etc. comprising a head, a grip and a shaft connecting these two parts.

[0002]

2. Description of the Related Art In general, a golf putter has a head composed of a blade having a face surface and a sole extending substantially horizontally rearward from the bottom of the blade, and both are integrally formed of metal. . Therefore, the head is a heavy metal structure that is heavy and does not easily deform.

[0003]

A golf putter having a head of such a tough metal structure avoids giving a strong hard feel to a hand or arm when hitting a golf ball because of a large rebound. I couldn't do it. Therefore, one of the main objects of the present invention is to provide a golf club having a soft feel when hitting a golf ball.

[0004]

The present invention provides a head unit,
A grip portion and a shaft portion connecting the two portions, wherein the head portion comprises a blade having a face surface, and a sole extending substantially horizontally rearward from the bottom portion of the blade, and the blade is provided at the bottom portion of the face surface. A golf club having a pair of slits extending upward from a vicinity thereof and sandwiching a substantially central portion of the face surface, and being bent along the way to connect with each other or penetrating upward.

That is, according to the present invention, a golf ball is formed by forming a pair of slits on a blade of a head that extend upwardly across a substantially central portion of a face surface and penetrate or bend in the middle to connect with each other. The part hit when hit (the part sandwiched by a pair of slits) can be partially deformed (slightly deflected backward), so that the golf ball deforms for a short time but is held This softens the repulsion and softens the feel when struck. Here, the blade and a pair of slits formed on the blade have a blade thickness (width) of 5 to 10 mm and a slit length (vertical dimension).
It is preferable that the slits are set to 20 to 30 mm, the interval between the pair of slits to be 45 mm or more, and the width (gap) of the slits to 0.2 to 0.4 mm.

In the present invention, in addition to forming a pair of slits in the blade as described above, a slit may be formed in the sole. For example, the slit can be formed so as to penetrate rearward along and / or parallel to a center line extending in the front-rear direction of the sole.

The golf club according to the present invention can be applied to golf putters, sand wedges, irons and the like, and is particularly suitable for golf putters. The material of the head portion is not particularly limited, but in the case of a putter, mild steel,
Brass, copper, nickel silver, and titanium alloys are preferred, and mild steel is more preferred.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on an embodiment shown in the drawings. Note that the present invention is not limited to this. [Embodiment 1] FIG. 1 is a perspective view of a golf putter as one embodiment 1 of a golf club according to the present invention as viewed from the rear, and FIG. 2 is a perspective view of the golf putter from the front. 3 is a plan view of the putter of the golf club.

First, in FIG. 1, a golf putter 1 is shown.
Consists of a head 2, a grip 3, and a shaft 4 connecting these two parts. Reference numeral 5 denotes a neck as a part of the shaft 4.

The head 2 comprises a blade 6 having a face surface 13 and a sole 7 extending substantially horizontally rearward from the bottom of the blade in FIGS. 9, and the sole 7 has three slits 10, 11, and 12, respectively. S is a sweet spot.

First, the slits 8 and 9 of the blade 6 are positioned symmetrically with respect to the sweet spot S.
From the bottom (from the height of the upper surface of the sole 7).

On the other hand, the slit 10 of the sole 7 penetrates rearward along a line (center line X in FIG. 3) passing through the sweet spot S. Slits 11 and 12
Are formed symmetrically about the slit 10 and penetrate rearward from near the rear surface of the blade 6. Here, the head 2 and the neck 5 have substantially the entire outer shape integrally formed by cutting mild steel, and then the slits 8.9 and the slits 10 are formed by a wire cutting (cutting) method.
11 and 12 are formed. Here, the thickness (width) of the blade 6 is 8 mm, the width (gap) of each slit is 0.3 mm, the length (vertical dimension) of the slit 8.9 is 27 mm, and the interval between the pair of slits 8.9 is 45 mm. The thickness of the sole 7 (thickness of the thin portion where the slit is formed) is 3 m.
m, length of slits 10, 11, 12 (horizontal dimension)
Is 25 mm, the interval between the slits 10, 11, 12 is 15 mm, and the width (gap) of each slit 10, 11, 12 is 0.3 mm. In FIGS. 1 to 3, the width (gap) of each slit is shown.
Dimensions are drawn larger than actual for ease of understanding. The same applies to FIGS. 4 and 5 described later.

Next, the operation of the golf putter 1 having the above configuration will be described. First, when a ball (not shown) is hit at a substantially central portion of the face surface 13 of the golf putter 1,
Due to the presence of the slits 8, 9, the ball is pushed forward by the repulsive force mainly of the portion of the blade 6 between the slits 8, 9 instead of the entire blade 6. In this case, only the portion between the slits 8 and 9 of the blade 6 bends (deforms) slightly rearward around the bottom side, and for a short time, pushes the golf ball forward after holding the golf ball. The repulsive force for pushing the ball forward is softer than in the conventional case without a slit, so that the impact on the player, that is, the feel is soft.

On the other hand, the portion of the blade 6 outside the slits 8 and 9 does not directly receive the impact of hitting the golf ball, and therefore has a large kinetic energy together with the thick portions located on both sides of the sole 7 and thus has a forward kinetic energy. Head to. here,
Since the slits 10, 11, and 12 are formed in the sole 7, the slits are deformed so as to be slightly opened, and the entire head 2 is bent in a bow shape as indicated by Y in FIG.
Thus, the face surface 13 of the blade 6 bends in response to the deflection, and the direction (trajectory) of the struck golf ball can be corrected to approach the center line X, albeit slightly. The slits 8.9 from above the blade 6
If one wants to avoid seeing, a cover may be placed on the upper surface of the blade 6. Also, the slit 10 of the sole 7
Is convenient because it gives an indication of the direction of hitting the ball together with the sweet spot S and the point to hit.

[Embodiment 2] FIG. 4 is a perspective view of a golf putter as another embodiment 2 of the golf club according to the present invention as viewed from the front, and FIG. 5 is a plan view of the same golf putter. is there. 4 and 5, the golf putter 21 is different from that of the first embodiment in that a pair of slits formed in the blade is bent without penetrating upward and connected to one another. Different. That is, before the slits (parts) 28 and 29 of the blade 26 penetrate upward, they are bent together and connected to one by the slit 34. Thus, when the ball is hit at a substantially central portion of the face surface 33 of the golf putter 21, the slits 28, 29, and 34 connected to one putter mainly cause the slit (part) of the blade 26 instead of the entire blade 26.
The ball is pushed forward only by the repulsive force of the portion between 28 and 29, and the impact on the player, that is, the feel, becomes soft as in the case of the first embodiment.

Further, as in the case of the first embodiment, since the slits 30, 31 and 32 are formed in the sole 27, the direction (orbit) of the hit golf ball can be corrected so as to approach the center line. Is the same. In addition, the putter 21 of this golf is provided with the slit 2 from above the blade 26.
Since 8.29 is not visible, it is convenient for players who do not want to see it.

The blade 26 has slits 28, 29 and 34
For example, first, a small through hole is formed by drilling at the lower end portion of the slit 28, and then a wire is passed through this through hole, and the slits 28, 29, and 34 are formed by the same wire cutting method as in the first embodiment. In order. Other configurations and operations of the putter 21 for golf according to the second embodiment are the same as those of the first embodiment, and a description thereof will be omitted.

[0018]

According to the present invention, a golf club is formed by forming a pair of slits on a blade of a head, which extend upwardly in a pair with a substantially central portion of a face surface interposed therebetween and penetrate or bend in the middle to be connected to each other. The part hit by the ball when hit (the part sandwiched between a pair of slits) can be partially deformed (slightly deflected backward), so that the part where the golf ball deforms is a short time Are held to soften the repulsion and soften the feel when struck.
