Description

Description: TECHNICAL FIELD The present invention relates to a golf club set that can satisfy the desire of concentration and shot accuracy at the time of shot not only by advanced users but also by beginners.

[Conventional technology]

A factor that determines the concentration and accuracy of a shot at the time of a shot is the sweet area of the club face.

The mass distribution of the club face, which determines the size of the sweet area, has a clear difference between the wood set and the iron set in the conventional commercially available club set, and the iron and wood basically have the same number for each number. Have the same form.

The golf club's sweet area is determined by the area of the club head from the center of the mass to the top, bottom, left, and right. The area where the height of about 80% is obtained from the spot (center of gravity) is called a sweet area. The sweet area can be determined by providing a vibration sensor above the shaft and hitting the face surface to measure a surface with less vibration shock.

The difference in the sweet area between the wood and the iron club is a very difficult point for a general amateur golfer, and is one of the major problems to be solved when adjusting a golf club set.

As one means for solving this problem, a series of sets having the same basic shape has been developed. This contiguous set has a mass distribution tailored to either iron or wood, with only the sweet spot of the golf club set being common across all clubs, and those with a large sweet area are large As it is, the narrow club is set as it is.

[Problems to be solved by the invention]

One of the real pleasures of playing golf is the concentration of the ball in the sweet area when hitting the ball and the accuracy of the hitting ball. If these are successful, a truly enjoyable golf play can be enjoyed. However, as shown by hatching in FIG. 1, the sweet area of the conventional golf set has a narrower sweet area S1 for professionals (a) such as professionals and singles. With emphasis, and for beginners to average golfers (b), a set of clubs having a relatively large sweet area S2 is set and has a low center of gravity.

This means that for beginners, only clubs with a large sweet area, in other words, clubs that are not focused on themselves and have a low center of gravity and no ball growth, will be given to beginners and intermediate players. During the season, the real pleasure of golf cannot be enjoyed. Even beginners and intermediate golfers should concentrate on the ball with the aim of the hole cup as long as they play golf, and simply using a club with a large sweet area with a lazy ball hinders progress as a golfer. Not fun.

In recent years, there have been many clubs with a low center of gravity or a change in the depth of the center of gravity, but none of them emphasizes the characteristics of the club itself and has no idea about adjusting the sweet spot of the entire club set.

SUMMARY OF THE INVENTION An object of the present invention is to provide a golf club set in which a senior can become a senior, and even a beginner can enjoy a concentration of shots and an accurate flight of a hit ball.

That is, even if it is a beginner, it is an object of the present invention to adjust a club set capable of swinging at a club where a person can concentrate on a place to be concentrated and a place where concentration is required.

As human beings grow up from birth, they have their own intuition and personality. It is necessary to cherish the intuition and individuality, train them alive, and have fun.

All traditional clubs have the same personality, and it is difficult to develop a wonderful intuition and personality of a person with a personality rhythm of the same spot with little change.

In this state, the intuition and personality of the people who use it are hard to make use of, and it seems that it gradually becomes dull. It may be a little intuitive if you work hard every day like a pro, just by practicing, but it is difficult for general amateurs. We value each person's wonderful natural intuition and individuality, and use the changing suite area club to nurture the hobby, artistic and individual intuition of score creation, It seeks to feed the wonderful living art of rhythm and feeling into play. Golf is not only about scoring, but also about playing as a hobby or art.

That is, the most important object of the present invention is to solve the problem of intuition and individuality of a golf club.

[Means for solving the problem]

The present invention reduces the length of each club face at a certain height level from the bottom surface according to the loft angle of the club face, and changes the size of the sweet area of the club face to the loft angle of the club face. It is a golf club set characterized in that it is sequentially reduced in size.

This can be combined with reducing the face height according to the face loft angle and increasing the center of gravity according to the club face loft angle.

Conventionally, the length of the face has been unified with a set club that is almost constant length, for example 90 mm, but the length of the long club face is long and the short is short, so that the length of the sweet area is shortened. adjust.

Long clubs, which are considered difficult for beginners, are created by expanding the sweet area with emphasis on ease of hitting, middle clubs are gradually reduced, and short clubs are clubs that are relatively easy to hit even for beginners Therefore, it is possible to expect a challenge to the accuracy of the hit ball by setting the club in which the sweet area is concentrated.

As for the adjustment of the sweet area, it is assumed that the sweet spot is concentrated as the advanced level, and the difference between the club numbers is reduced, and for the advanced level, the concentration of the shot and the hit ball Gain accuracy.

〔Example〕

FIG. 2 shows an embodiment of the present invention using an iron as an example. This figure shows the relationship between the club having a reduced number of lofts, that is, the club having a reduced number of clubs and the face length. As shown in the figure below, the face length b at the position of the level a of 8/5 inch from the bottom, the example of beginner, intermediate and advanced,
These are indicated by X-rays, Y-lines and Z-lines, respectively. For intermediates shown on the Y line, an iron with a 55 ° loft angle adjusts the face length to 90mm, and for a 10 ° loft, 99mm
Is set to With this, in the case of an intermediate player, in the case of a long iron that is relatively difficult to hit, the length of the face is increased to 99 mm to make it easier to hit. And for short irons that are easy for intermediate players to hit, the length of the face is adjusted to 90mm to improve the sense of concentration of the hit ball. For beginners, as shown on the X-ray, for a long iron with a loft angle of 10 °, 90
mm to make it easier to hit, and adjust the face length to be longer than the Y-line for intermediate players in order to make the sweet spot area larger than the sense of concentration of the shot even with short irons with a large loft angle. ing. However, in order to obtain a sense of concentration of the hit ball, the face length is adjusted to be shorter as the loft angle becomes larger. Furthermore, in the case of an advanced player who easily hits the sweet spot of the club, the rate of increase in the face length is smaller than that of the intermediate player in order to emphasize the sense of concentration of the hit ball.

FIG. 3 shows a change in the sweet spot area by adjusting the length of the face shown in FIG. In the figure,
As shown in the curve X, the beginner's club set uses a long club having a small loft with a relatively large sweet area, and a short club having a large loft has a medium sweet area. In addition, in the case of the curve Y for intermediates with a handicap of about 20, it is for intermediates who can expect relatively accurate shots up to the middle club, and the long club has a sweet area about the same size as a beginner It becomes smaller in a short club. In the case of curve Z, which is a curve for advanced users who can expect accurate shots, the sweet area of the long club is wider than that of the short club, but the difference is small, so that the concentration of the shots is small. It is set so that sex can be expected even in a long club.

In the above, an example of the change of the sweet spot area only by adjusting the length of the face has been described, but the height of the face is reduced according to the loft angle of the face,
In addition, by adjusting the center of gravity to be higher according to the loft angle of the club face, the adjustment of the sweet spot area can be further increased.

The above can be used in a putter set. However, in the case of a putter, the loft of -2 is located on the outside of the neck part which is the shaft position, the loft of +2 is attached slightly inside, and the loft of +7 is located at the center position.
It is good to put it around 1cm.

The size and width of the sweet area based on the mass distribution described above can be realized by changing the design of the club head.

〔The invention's effect〕

According to the club set of the present invention, (1) By setting the long club to have a long face and the short club to be short, the long club can be made to fly farther and more accurately, and the short club can be precisely controlled in direction and distance. Become a good club.

(2) In addition, amateur beginners as well as beginners and intermediate players can enjoy the full thrill of golf due to the concentration of shots and the accuracy of hit balls.
