Definitions
- the present invention relates to a utility iron, and more particularly, to a utility iron that can increase the flying distance more stably.
- the golf is recognized as a popular sport, the golf has been widely spread for the purpose of exercise and leisure mainly in the elderly.
- Such a golf is a game in which a golf ball is put into a hole of a certain size using a variety of golf clubs with a small number of strokes, and the club is hit by selecting a club according to the distance to the hole cup and the situation of the ground.
- the driver hits the golf ball and blows it 200-300 meters to settle on the fairway, and selects a variety of irons and woods depending on the distance from the ball position to the hole cup. After the ball is blown, the golf ball is pushed into the hole cup using a putter on the green.
- the golf ball is hit by selecting various irons and woods according to the distance between the golf ball and the hole cup falling on the fairway.
- an appropriate club should be selected according to the body shape and the hitting habit.
- Figure 1 shows the distance of the golf ball when hitting the golf ball accurately using a variety of conventional irons and woods, as shown, in the case of nine irons the golf ball floats high, while the short distance, As you go to the iron, you can see that the golf ball floats lower, resulting in a longer distance.
- the present invention has been devised in view of the above problems, the loft angle is small and the lie angle is relatively large, the weight of the head and the length of the shaft is relatively short, to increase the repulsion force due to the collision of the head and the golf ball
- it aims to provide a utility iron that can reduce the swing trajectory and increase the accuracy of the hitting and the flying distance accordingly.
- the lie angle is 58 to 64 degrees
- the loft angle is 20 to 28 degrees
- the weight of the head is 270 to 300g
- the length of the shaft is 35 to 38 inches It is done.
- the loft angle is relatively reduced, so that the golf ball does not float high, thereby providing an effect of increasing the flying distance.
- the lie angle is relatively large to provide an effect of reducing the risk of the occurrence of hooks or slices.
- the repulsive force due to the impact with the golf ball is increased, so that the distance of the golf ball can be relatively increased, and the length of the shaft is shortened to reduce the swing trajectory, so that accurate hitting is easier. It also provides the effect of increasing the distance.
- 1 is a view showing the distance of the golf ball when hitting the golf ball accurately using a variety of conventional irons and wood.
- Figure 2 is a front view of the head of the utility iron according to the present invention.
- FIG. 3 is a side view of the head of the utility iron according to the present invention.
- FIG. 4 and 5 is a view showing the measurement results of the flight distance using the utility iron according to the present invention.
- FIG 2 is a front view of the head of the utility iron according to the present invention
- Figure 3 is a side view of the head of the utility iron according to the present invention.
- Utility iron 10 is composed of a head portion 12 to hit the golf ball, and a shaft 14 to be held by the golfer by hand.
- the weight of a head part is 270-300g
- the loft angle is 20-28 degree
- the lie angle is 58-64 degree
- the length of a shaft is 35-38 inches.
- the weight of the head is relatively large as compared to the low order irons, the repulsive force due to the collision with the golf ball is increased, so that the distance of the golf ball is increased.
- the golf ball since the loft angle is relatively small compared to the iron of the high turn, the golf ball does not float much up, and the distance of the golf ball increases.
- the shaft may be swinged while being held close to the vertical without laying the shaft, thereby reducing the possibility of the hook or slice being generated.
- the swing trajectory is reduced, so that the swing during the swing is reduced, so that it is easy to accurately match the golf ball to the center of the head relatively.
- a utility iron with a weight of 284 g of head, 22 degrees of loft angle, 62.5 degrees of lie angle, and 36 inches of shaft length was manufactured.
- the shape of the head is a typical iron shape, and the shape is distinguished from a conventional wood or utility having a Dip Face in order to achieve high elasticity.
- Table 4 above is an experimental value obtained by hitting the golf ball 10 times as the average value of the swing speed using the 9 irons.
- Table 5 above is an experimental value obtained by hitting the golf ball 10 times as the average value of the swing speed using the 9 irons.
- the swing machine was performed under the same conditions (same room temperature, the same swing speed and the same force) when hitting the golf ball using a utility iron.
- PGA players hit four golf balls 10 times at the average value of swing speed using 9 irons
- LPGA players hit 4 golf balls 10 times at the average value of swing speed using 9 irons. Each experiment was conducted by hitting.
- the utility iron according to the present invention as a result of the hitting test under the same conditions (swing speed) as the nine irons used mainly by golfers, as shown in Table 6 and Table 7, the distance (golf ball falls to the ground) Distance to the site) was 41 yards more than the average distance of PGA and 46 yards of the average distance of LPGA.
