Abstract

(57) [Summary] [Purpose] To facilitate selection of a golf club that provides a backspin amount according to the skill and preference of a golfer. According to the head speed of an average amateur golfer, a symbol S corresponding to the amount of backspin given to a ball when hitting the ball is displayed on the golf club.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a golf club, and more particularly to a golf club displaying the amount of backspin that can be applied to the ball when hitting the ball.

[0002]

[Prior art]

 Conventionally, as a device focusing on the backspin amount of a hit ball, the one described in Japanese Utility Model Publication No. 6-86755 is known. This shows a symbol corresponding to the backspin amount on the surface of the golf ball.

[0003]

[Problems to be solved by the device]

 The backspin amount of a hit ball is greatly influenced by the difference in head speed, and the backspin amount of the material forming the face surface of the golf club head, such as carbon fiber reinforced plastic, is higher than that of soft iron or stainless steel. Low, copper has more backspin than soft iron. Therefore, even if the amount of backspin is displayed on the surface of the ball, the backspin amount cannot be obtained as shown, depending on the golf player's head speed and the golf club used.

Therefore, an object of the present invention is to provide a golf club capable of obtaining a backspin amount according to a golfer's skill (head speed, swing characteristics, etc.) and preference.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention displays on the golf club a symbol corresponding to the amount of backspin imparted to the ball at the time of hitting the ball, based on the head speed of an average amateur golfer. In addition, a symbol corresponding to the amount of back spin given to the ball at the time of hitting the ball is displayed on the golf club in correspondence with the symbol corresponding to the golf player's head speed.

[0006]

[Action]

 By selecting a golf club with a large amount of backspin, a high backspin can be imparted to the ball, good ball control can be achieved with a short iron, and a driver (1st wood) can intentionally hit a draw ball or fade ball. It will be easy. On the other hand, if you select a golf club with a small amount of backspin, the ball will be less likely to get backspin, and therefore the side spin will be less likely to take place, and extreme hooks and slices will be less likely to occur, making it less susceptible to the effects of wind. Furthermore, the backspin amount also differs depending on the type of ball.For example, a wound ball generally has a higher backspin amount than a two-piece ball, but it depends on the structure of the golf club, the materials used, and the head speed of the golfer. Since the amount of backspin given to the ball is influenced more and more, displaying the amount of backspin corresponding to the head speed on the golf club is more realistic than displaying the amount of backspin on the ball. The backspin amount of the ball when hit by is more accurate.

【Example】

 A preferred embodiment of the present invention will be described below with reference to the drawings.

The embodiment shown in FIG. 1 shows a so-called wood club among golf clubs, in which a shaft 1 is attached to a head 1 and a grip 3 is attached to the tip of the shaft 2. In this embodiment, a symbol S corresponding to the amount of backspin imparted to the ball at the time of hitting the ball is displayed on the shaft 2 on the basis of the head speed of an average amateur golfer. The display location of the symbol S may be displayed on the crown portion 11 of the head 1 instead of the shaft 2. The head speed of the driver (No. 1 wood club) is extremely wide, ranging from 25 to 50 m / sec including men and women, but the average head speed of an average male golfer is 36 to 42 m / sec. The average female golfer's head speed is about 26 to 32 m / sec. Therefore, in the men's wood club, the symbol S corresponding to the amount of back spin is displayed based on the head speed of the average amateur golfer of the men. In the case of a women's wood club, the symbol S corresponding to the amount of backspin is displayed based on the head speed of the average amateur golfer of this girl.

When a wood club called a driver hits a commercially available general-purpose two-piece ball (Our Altus Calead of our company) at a head speed of 38 m / sec with three types of drivers A to C, the average of the drivers A is The backspin amount was in the range of 2000 to 2500 rpm / sec, in the range of 2500 to 3000 rpm / sec in the driver B, and in the range of more than 3000 rpm / sec in the driver C. The same ball and the same head speed, but different backspin amounts are due to the materials and structure of the golf club used, such as high or low center of gravity or different loft angles, as well as differences in shaft flex or kick points. It depends on various conditions. For a low spin driver A, a symbol S such as BS-L (low spin) is attached as a symbol S, a driver B has a BS-M (medium spin), and a driver C has a BS-H (high spin). The symbol S such as "spin" is displayed. The symbol S such as BS-2000, BS-2500, BS-3000 may be attached instead of the symbol S such as BS-L, BS-M, and BS-H. In this case, the backspin amount is displayed as having a slight range in the rotation speed display. Those who have a head speed that is higher than the average amateur golfer's head speed may make club selections in consideration of the fact that the amount of backspin displayed by the symbol S is greater than that of the average head speed. A golfer with a head speed even slower than that may select a golf club in consideration of the fact that the backspin amount is smaller than the displayed backspin amount.

Generally, a golfer with a driver head speed of 45 m / sec or more is called a hard hitter, a golfer of 40 to 45 m / sec is called a semi-hard hitter, and a golfer of 35 to 42 m / sec is called a standard. A golfer with a speed of 35 m / sec or less is called a swinger. Then, symbols corresponding to four types of head speed, hard hitter, semi-hard hitter, standard, and swinger, for example, black, red, green, and blue are displayed in the order of head speed, and the head speeds are associated with each other. By displaying the symbol S corresponding to the backspin amount given to the ball at the time of hitting the ball on the golf club, the backspin amount that can be given to the ball by the selected golf club becomes accurate. The advanced player does not always have a high head speed, and there are advanced players even in swingers with a slow head speed, so the player is an advanced player who intentionally bends the ball or backspins with a short iron. If you want to stop the golf course, you should choose the blue marked BS-H golf club. Also, some beginners have hard hitters with fast head speeds, so those who choose a black BS-L golf club can extend the flight distance with less bending.

FIG. 2 shows an example in which the symbol S corresponding to the backspin amount is displayed on the sole 12 of the head 1 or on the peripheral portion 13. The hardness, weight, and bending degree of the shaft 2 also affect the backspin amount given to the ball, but the backspin amount given to the head 1 is particularly influenced by the structure of the head 1, the material used, and the like. It is effective to display. Further, since the shaft 2 can be replaced, displaying the backspin amount on the head 1 does not significantly affect the backspin amount given to the ball even after the shaft 2 is replaced. Although the embodiment described above has been described for the wood club, it is a matter of course that a so-called iron club can also display a symbol corresponding to such a backspin amount. In iron clubs, the head speed changes depending on the iron number, so the symbol S corresponding to the backspin amount is displayed in consideration of the head speed for each iron number. Alternatively, since iron clubs are generally sold as a set of 9 or 10, a symbol corresponding to the amount of backspin in this set is displayed for each group of short iron, middle iron, long iron, etc. May be. Alternatively, for some iron golf club sets, it may be represented as BS-L, BS-M, BS-H based on the head speed of an average amateur golfer. Also, a symbol corresponding to the backspin amount can be displayed on the set in association with symbols corresponding to several types of head speed.

[Effect of device]

 As described above, according to the present invention, the golf club has a symbol corresponding to the backspin amount given to the ball when hitting the ball, based on the head speed of the average amateur golfer. The golf club can be selected according to the golf club, or the golf club can be selected according to the golfer's preference. Further, displaying the backspin amount on the golf club rather than displaying the backspin amount on the ball makes it possible to obtain an accurate backspin amount regardless of the head speed or the structure of the golf club. In particular, when a symbol corresponding to the amount of backspin imparted to the ball at the time of hitting the ball is displayed in correspondence with the symbol corresponding to the golf player's head speed, even if the golf club has the same structure, the difference in head speed Since the amount of backspin that can be given to the ball differs depending on the type, if the amount of backspin that matches your head speed is displayed, you can easily make a game and score with a golf club that suits you. You can choose. It is also possible to select a golf club according to the weather of the day and the characteristics of the golf course to be played.
