Abstract

The present invention relates to a utility iron which is characterized in that it has a lie angle of 58 to 64 DEG, a loft angle of 20 to 28 DEG, a head weight of 270 to 300 g, 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

Multi-functional iron

Technical field

The present invention relates to multi-functional iron, in more detail, relate to the multi-functional iron that stably can increase flying distance.

Background technology

In recent years, along with the prosperity of industry, quality of life also improves, and golf is recognized as popular motion, and based on person in middle and old age's layer, the trend that golf is in motion and idle object and spreads.

Golf, for utilizing various golf clubs, to be squeezed into the game in the match play of prescribed level by this golf with few batting number, select club to impact according to the situation in the Distance geometry court from match play.

Such as, utilize to drive at service area (Tee ground) and impact golf, ball is beaten and flies to about 200 ~ 300 meters, make it be placed in fairway, and in the position of falling sphere, select various iron and rod according to the distance from match play, after golf Da Feizhiguo ridge, in fruit ridge, utilize push rod, golf ball is got to match play.

Now, according to the distance dropped between the golf of fairway and match play, select various iron and rod to impact golf, in the case, according to the build of self and impact custom etc., suitable club should be selected.

Fig. 1 is utilizing existing various iron and rod for illustrating, the flying distance of golf when correctly impacting golf, as shown in the figure, when No. 9 irons, because golf flies high, flying distance is short, on the contrary, utilizes more small size iron, golf flies lower, can know flying distance thus longer.

Its reason is that loft is larger, thus can be easier to the flight of golf because of number larger iron.

When golf clubs, to there are differences a little between each manufacturer, but the iron of more large size, its loft and bar base angle larger, and the weight of bar head is greatly, and on the contrary, the length of shaft shortens.

Therefore, most amateur is easier to play the golf flying to be placed on fairway, thus the iron of large size is mainly used, so that the error of batting (Topping) in minimizing, and the heavier-weight of bar head, and can improve impact bring bounce, reduce to swing angle, reduce the probability of Draw or miss.

Namely, due to the iron that number is larger, loft is larger, and can be easy to beat fly golf, the weight of bar head is large, thus can improve impact bring bounce, and, the length of shaft is short and reduce swing trajectory, therefore uses golf easily by the iron of the large size of the center of bar head impact.

But, as mentioned above, when the iron of large size, because the weight of bar head is large, and the relation that the length of shaft is short, compared with the iron of trumpet, be easier to impact correct impact point, but as shown in Figure 1, because of the relation that loft is large, the elasticity grow of golf, and there is the problem being difficult to increase flying distance.

Further, when the iron of large size, compared with the iron of trumpet, because of the relation that bar base angle and loft are together larger, thus there is the Draw that occurs to swing based on plane or the hidden danger based on the miss vertically swung.

Therefore, in order to solve problem as above, and select small size iron to impact golf, when the iron of trumpet, because loft is relative with bar base angle little, if and make the center of bar head correctly impact golf, then flying distance can be increased, but bar head is lightweight, and the length of shaft is long, and most amateur is difficult to correctly impact, result causes many errors that batting and Draw and miss etc. occur.

Summary of the invention

Technical problem

The present invention proposes in view of problems as above, the object of the present invention is to provide following multi-functional iron, namely, there is little loft and relative large bar base angle, the Heavy Weight of bar head, the length of shaft is relatively short, the bounce that the shock improving bar head and golf thus brings, and by reducing swing trajectory, correct impact and the flying distance based on this can be increased.

The means of dealing with problems

For realizing the of the present invention multi-functional iron of object as above, it is characterized in that, bar base angle is 58 ~ 64 degree, and loft is 20 ~ 28 degree, and the weight of bar head is 270 ~ 300g, and the length of shaft is 35 ~ 38 inches.

The effect of invention

As mentioned above, according to multi-functional iron of the present invention, provide following effect, that is, loft reduces relatively, golf cannot be made to soar, thus can increase flying distance.

Further, provide following effect, that is, bar base angle becomes large relatively, can reduce occur Draw or miss hidden danger.

Especially, following effect is provided, namely, the weight of bar head becomes large and increase brings with the impact between golf bounce, relatively can increase the flying distance of golf, and the length of shaft shortens relatively, swing trajectory is shortened, be easier to thus realize correctly impacting, increase flying distance.
