Utility iron

Abstract

The present invention relates to a utility iron which is characterized in that it has a lie angle of 58 to 64°, a loft angle of 20 to 28°, a head weight of 270 to 300g, and a shaft length of 35 to 38 inches. Thus, the loft angle is relatively reduced so as to prevent a golf ball from being hit high and increasing flight distance. Also, because the lie angle is relatively increased, the possibility of a hook or a slice occurring is reduced. Because the weight of the head is increased, repulsive force is augmented by the striking of the golf ball, which relatively increases the flight distance of the golf ball. Because the length of the shaft is relatively shortened, swing trajectory is reduced, and accurate striking is made easier so as to also increase flight distance.

Description

TECHNICAL FIELD[0001]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.BACKGROUND ART[0002]As the quality of life becomes better thanks to the development of industries, 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.[0003]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.[0004]For example, 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...

Benefits of technology

[0016]As described above, according to the utility iron of the present invention, the loft angle is relatively reduced, so the golf ball does not fly too high, which means that the driving distance can be increased.

[0017]Also, the lie angle relatively increases, so it is possible to decrease any concerns involved in hook or slice.

[0018]In particular, 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.

Problems solved by technology

The irons with the higher numbers have greater loft angles and lie angles, and the weight of the head is heavy, and the length of the shaft becomes short.

As described earlier, in case of 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.

In case of the irons with the lower numbers, the loft angles and the lie angles are relatively smaller, so it is possible to increase the driving distance when hitting the golf ball with the center of the head; however since the head is light, and the length of the shaft is long, almost amateur players have difficulties in accurately hitting the golf ball, thus causing a lot of mistakes such as topping, hook and slice.
