Definitions

  • the present invention relates to a utility iron, and in particular to a utility iron which makes it possible to surely increase a driving distance during a golf game.
  • a golf game is recognized as one of the popular sports, so the golf game is widely spreading because middle and old-aged persons who enjoy exercise and leisure increase.
  • Such a golf game is performed in such a way that a player tries to input, using a variety of golf clubs, with less number of hits, a golf ball into a hole cup with a predetermined size. The player selects a club depending on a distance to a hole cup and a situation of the ground and then hits the golf ball.
  • the player drives on the tee ground a golf ball using a driver to land the golf ball onto a fairway after a flight of 200 ⁇ 300 meters.
  • the player selects various irons and woods based on the distance from where the golf ball has landed to a hole cup and hits the golf ball onto the green.
  • the player hits the golf ball into a hole cup using a putter and puts into the hole cup.
  • the player selects various irons and woods based on the distance from the golf ball landed on the fairway to the hole cup and then hits the golf ball. In this case, the player selects a proper club based on the body type of the player and hitting habit.
  • FIG. 1 is a view illustrating a driving distance of a golf ball when a player accurately has hit a golf ball using various conventional irons and woods. As illustrated therein, the nine iron has a short driving distance while the golf ball flies high, and the irons with the lower numbers have relatively longer driving distances while the golf ball flies low.
  • the irons with the higher numbers are capable of easily lifting up the golf ball thanks to the greater loft angles, and the repulsive power against the impacts may be increased due to the heavy head. Since the length of the shaft is short, the swing trace is decreased, and the player may easily hit the golf ball with the center of the head, so the irons with the higher numbers are more used.
  • the irons with the higher numbers it is easier to accurately hit the hitting point thanks to the heavier head and the shorter shaft length as compared with the irons with the lower numbers; however as illustrated in FIG. 1 , the irons with the higher numbers have the greater loft angles, so the grade of elasticity of the golf ball is high, which makes it hard to increase the driving distance.
  • the present invention is made in an effort to improve the above-described problems. It is an object of the present invention to provide a utility iron which makes it possible to obtain an accurate hitting for thereby increasing a driving distance in such a way to increase a repulsive power against an impact between a head and a golf ball and reduce a swing trace because a head is heavy and a shaft is relatively shorter while relatively increasing a loft angle and a lie angle.
  • a utility iron wherein a lie angle is 58 ⁇ 64°, a loft angle is 20 ⁇ 28°, the height of a head is 270 ⁇ 300 g, and the length of a shaft is 35 ⁇ 38 inches.
  • the loft angle is relatively reduced, so the golf ball does not fly too high, which means that the driving distance can be increased.
  • the lie angle relatively increases, so it is possible to decrease any concerns involved in hook or slice.
  • the weight of the head increases, and the repulsive power against the impact with the golf ball may also increase, thus relatively increasing the driving distance of the golf ball.
  • the length of the shaft is relatively shortened, so the swing trace decreases, by means of which an accurate hitting is possible also along with the increased driving distance.
  • FIG. 1 is a view illustrating a driving distance of a golf ball when a player accurately hits the golf ball using various related irons and woods.
  • FIG. 2 is a front view illustrating a head of a utility iron according to the present invention.
  • FIG. 3 is a side view illustrating a head of a utility iron according to the present invention.
  • FIGS. 4 and 5 are views illustrating a result of measurements during a driving distance experiment using a utility iron according to the present invention.
  • FIG. 2 is a front view illustrating a head of a utility iron according to the present invention.
  • FIG. 3 is a side view illustrating a head of a utility iron according to the present invention.
  • the utility iron 10 comprises head 12 configured to hit a golf ball, and a shaft 14 a golf player grabs with hands.
  • the weight of the head is 270 ⁇ 300 g
  • the loft angle is 20 ⁇ 28°
  • the lie angle is 58 ⁇ 64°
  • the length of the shaft is 35 ⁇ 38 inches.
  • the loft angle is relatively smaller than the irons with the higher numbers, the golf ball is not lifted up too high, so the driving distance of the golf ball also increases.
  • the swing trace may be decreased, which results in the prevention of any swaying during the swing. So, it is easy to easily and accurately hit the golf ball against the center of the head.
  • the utility iron was manufactured, wherein the weight of the head is 284 g, the loft angle is 22°, the lie angle is 62.5°, and the length of the shat is 36 inches.
  • the head has one of the typical head shapes of the irons, the shape of which is different from the shapes of a typical wood or other utilities each having a dip face formed for the sake of a high elasticity.
  • the table 4 shows the experimental values obtained based on the average values of the swing speed after the U.S.A. PGA players hit the golf ball 10 times using the nine iron.
  • the table 5 shows the experimental values obtained based on the average values of the swing speed after the U.S.A. LPGA players hit the golf ball 10 times using the nine iron.
  • the swing machine was set to operate under the conditions (same indoor temperature, same swing speed and same power) as when the golf ball was hit using the utility iron.
  • the utility iron of the present invention showed that the driving distance (to the point where the golf ball had landed on the ground) was 41 yards longer as compared with the average driving distance of the U.S.A. PGA and was 46 yards longer as compared with the average driving distance of the U.S.A. LPGA as seen in Tables 6 and 7 as a result of the experiments which were conducted under the same conditions (swing speed) as the nine iron that the golfers usually use.
