Abstract

<P>PROBLEM TO BE SOLVED: To provide a golf club head structure required for effectively achieving improvement of flexibility of a face plate, because it is effective that the face plate is made flexible for raising resilience performance to make deflection larger to relatively reduce deflection of a ball side because energy absorption is carried out almost by the ball side upon a collision of a club head with a ball when considering their materials. <P>SOLUTION: Though the face plate is combined with the head body, improvement of flexibility of the face plate is easily and freely attained and the resilience coefficient upon impact is raised by making a part of the combination part be a structure with slits and cutting off the combination of both at the part. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

[0001]
BACKGROUND OF THE INVENTION
According to the present invention, a slit is provided in the vicinity of the boundary between the club face portion and the head main body to increase the flexibility of the face plate, improve the resilience performance, and increase the flight distance (initial velocity) of the ball. It relates to the head.
[0002]
[Prior art]
Increasing the ball flight distance in golf is a desire of many golfers.
For this purpose, various ideas have been made on the material and structure of the club head, but the mainstream of the current technology is to increase the club head area as much as possible to increase the club face area and to make the face plate as thin as possible. As a result, the flight distance (initial velocity) of the ball increases.
[0003]
However, there is a limit to increasing the volume of the club head and making the face plate thin, and sufficient resilience performance cannot be obtained.
[0004]
[Problems to be solved by the invention]
Therefore, since there is a limit to increasing the size of the club head, it is effective to consider a method that can obtain sufficient resilience performance without using an expensive material regardless of the size.
[0005]
At present, the coefficient of restitution of the club head and the ball is about 0.8, which is considerably lower than 1.0, and tends to decrease as the head speed increases. Considering the cause, the material of the head is a metal or the like, and the head, particularly the face portion, is used within the elastic limit, so it can be considered an elastic body. However, the ball is not an elastic body because of its material and structure. In addition, due to its hysteresis characteristics, considerable energy absorption occurs upon impact. Therefore, it can be seen that almost all of the causes of the reduction in the coefficient of restitution are on the ball side. In other words, the coefficient of restitution is determined by the situation of the collapse of the ball, and decreases as the collapse amount of the ball increases.
[0006]
From the above facts, in order to increase the coefficient of restitution, the club face part, which is an elastic body, should be made as flexible as possible and deformed greatly, and the amount of energy absorbed can be reduced by relatively reducing the collapse of the non-elastic body ball. It can be seen that it should be reduced. For this purpose, in order to secure the strength of the face plate and to make it flexible, it is made thin by using high-quality materials (titanium, duralumin, ultra-high strength steel, amorphous alloy, etc.) and the head is enlarged to increase the face area. Increasing it is an effective means. However, there is a limit to the enlargement of the head and the thinning of the face plate, and sufficient flexibility cannot be obtained.
[0007]
[Means for Solving the Problems]
In the present invention, a structure is employed in which a slit is provided in a joint portion between a face plate and a head body of a wood and iron type club head (excluding a putter), and the joint is cut off at that portion.
In the hollow wood and iron head, basically, two slits having appropriate lengths and widths are provided along the inner surface of the face plate in the joint portion between the crown plate, the sole plate, and the face plate. In addition, one to four slits having an appropriate length and width are provided in the crown plate, the sole plate, the toe plate or the heel plate as necessary.
In an iron head having a cavity structure, a slit having an appropriate length and width is provided in a shape along the back surface of the face plate in a knob-like portion of the sole portion.
In a solid wood and iron head, a slit having an appropriate length and width is provided at a position retracted from the club face surface by an appropriate distance from the upper part to the lower part or from the front part to the rear part.
[0008]
According to the present invention configured as described above, since the coupling between the face plate and the head body is partially broken, the flexibility of the face plate can be made almost freely regardless of the area of the face and the material used. Can be increased. In addition, there is no necessity for the unreasonable enlargement and the use of high-quality materials that have been widely adopted recently by drivers, and it can be easily applied to club heads where enlargement is impractical, such as fairway wood and iron head.
Therefore, the amount of collapse of the ball at the time of impact can be made sufficiently small, and the coefficient of restitution increases, so that the initial velocity of the ball increases and the flight distance increases.
[0009]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows the appearance of the hollow wood head of the golf club of the present invention, and FIG. 2 shows the AA cross section of FIG. This is a representative example of the present invention, and two slits S having an appropriate length and width are provided in the crown plate 11 and the sole plate 12 along the inner surface 15 of the face plate 13.
P is a thickened portion for reinforcement and is provided as necessary.
In this example, the coupling conditions between the face plate 13 and the head bodies 11 and 12 are completely different from those of the conventional clubs, and sufficient flexibility of the face plate 13 can be easily obtained.
[0010]
FIG. 3 shows a cross section immediately after the face plate rear surface of the hollow wood club head according to the present invention, wherein C is a portion where the face plate 13 and the head body are coupled, and S is a position where a slit is provided. In the representative example of the present invention, two slits S1 and S2 are provided, but an arbitrary number (1 to 4) of slits S can be provided as necessary.
[0011]
FIG. 4 shows the appearance of an iron head having a cavity structure, and FIG. 5 shows a cross section taken along the line BB of FIG. The slits S are provided in the bump-like portion 16 of the sole in a form along the back surface 15 of the face plate 13. In this example, the flexibility of the lower part of the face plate 13, which is made highly rigid by the ridge-like part 16 of the sole in the current club, is greatly increased.
[0012]
FIG. 6 shows a cross section of a solid iron head. This is an example in which the slit S is provided in a form along the face surface 14 by retreating from the face surface 14 by an appropriate distance from the upper part to the lower part of the head.
7 and 8 show examples of the shape of the slit S. FIG.
FIG. 7 shows an example in which a straight slit is used, and FIG.
H is for preventing breakage due to stress concentration.
[0014]
【The invention's effect】
By adopting the structure with slits as described above and setting the thickness (rigidity) of the face plate and the shape and number of slits appropriately, the face plate is flexible regardless of the size and material of the head. Therefore, the rebound coefficient of the head can be made extremely high. Naturally, the initial velocity (flying distance) of the ball increases. In addition, it is not necessary to increase the size of the head and can be applied to clubs where the increase in size is inappropriate, and it is not necessary to be concerned with the use of high-quality materials. It is possible to provide a club that is extremely effective in terms of the flight distance desired by the golfer at low cost.
