Description

[Detailed description of the invention] This invention relates to a sole plate that is fixed to the wood head of a golf club.The purpose of this invention is to move the center of gravity of the wood head to the rear, increasing the efficiency of the hitting force, and making it easier to hit the ball. To make it easier to climb higher. Also, increase the moment of inertia around the center of gravity of the head to improve the directionality of the ball. What's more, it's about adding variety to the design.

Conventionally, a single metal sole plate of uniform thickness is fixed to the wood head of a golf club to protect the sole from wear and tear.
It had a monochromatic and bland appearance. It is known that if the back of the head is heavier, the efficiency of the hitting power increases and the ball is easier to hit, so it is possible to attach a metal such as brass, called back metal, to the back of the head separately from the sole plate. Although it has become common, the fixing process is time-consuming and the back metal is exposed, which is undesirable in terms of appearance.

On the other hand, it was also devised in the 1970s to make the rear of the head heavier by stacking core plate weights with small holes on the inner surface of the sole plate and inserting replaceable small weights into the small holes.
-22275. However, the sole plate itself in this case also uses a single monochromatic metal plate.

Therefore, this invention has achieved the above object, and an embodiment thereof will be described with reference to the drawings.

That is, it consists of two metal sole plates, an inner and outer sole plate, and the outer sole plate 1 is provided with holes 2 of arbitrary size and arbitrary number at the required rear part, and a convex part 3 that fits into the holes 2 is provided. sole plate 4
This is a sole plate for a golf club characterized in that the convex portion 3 is exposed by being superimposed on the inner surface of the outer sole plate 1 at a rear position away from the center of gravity of the entire wood head 5. In another embodiment, the convex portion 3 of the above embodiment is slightly depressed from the hole 2, as shown in FIG.

The two inner and outer sole plates 1 and 4 are made of different materials with different colors. Specifically, the outer sole plate 1 is made of a white metal such as an aluminum alloy or stainless steel, and the inner sole plate 4 is made of a white metal such as an aluminum alloy or stainless steel. This is more effective by using a golden-colored metal such as brass, which has a higher specific gravity than the outer sole plate 1.

As mentioned above, this idea consists of two sole plates, the inner and outer ones, and the outer sole plate 1 has two holes.
The convex portion 3 of the inner sole plate 4 fills the hole, and since the inner sole plate 4 is stacked so as to be distributed to the rear of the center of gravity of the entire wood head, this invented sole plate can be fixed to the wood head. As a result, weight is applied to the rear of the head, increasing the moment of inertia around the center of gravity of the head, increasing the hitting force and increasing flight distance. Even if the ball is hit close to the ball, the ball can be hit with relatively good direction.

Furthermore, since the two inner and outer sole plates 1 and 4 are made of different colors and different materials, a design change is brought about from the monochromatic and boring appearance, and the design effect is improved.

Further, when the protrusion 3 of the inner sole plate 4 fills the hole 2 of the outer sole plate 1, the protrusion 3 may be flush with the outer sole plate;
If the convex part 3 is slightly depressed from the hole 2 as shown in the figure,
The convex portion 3 never comes into contact with the ground.

Therefore, by marking the surface of the convex portion 3 with a mark 6 such as a trademark or a symbol, or by coloring it, it is possible to maintain its beauty without wear and tear.

In this way, by fixing this invented sole plate to the wood head, the golf club has the characteristics of increasing the efficiency of the hitting force, achieving a high hit with good direction, and also having an excellent design. .
