Golf club head and golf club

Abstract

In a golf club head having a shape of a Mallet-type patter, a width of a sole face is in a range of 30 mm to 80 mm. A loft angle of the golf club head is in a range of 10° to 40°. A thickness A of a top blade satisfies a relationship:10 mm≦A≦SW−5 mm.A weight of the golf club head is in a range of 350 g to 450 g.

Description

[0001] This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 2005-226862 filed on Aug. 4, 2005, the entire contents of which are incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The invention relates to an approach golf club, which is used for hitting a ball toward a pin from the periphery of the green and can be swung like a putting stroke, and its head. [0004] 2. Description of the Related Art [0005] Golf clubs called “jigger” or “chipper” are known as golf clubs for ordinary amateur golfers that are dedicated to approach shots. For example, a golf club is known whose head stands halfway between an iron club and a putter in overall shape. More specifically, its hitting face has a loft angle of about 30° to 42° and the front portion of a sole face is continuous with the bottom portion of the hitting face to form a leading edge. In approach golf clubs of this type, the wid...

AI Technical Summary

Benefits of technology

[0008] The invention provides a golf club head and a golf club, which decrease the probability of duffing by enabling a putting-like stroke, lower the center of gravity, increase the stability in both direction and distance so that the direction and distance fall within prescribed ranges for shots made by a wide area of the hitting face and make approach shots easier.

[0011] According to the structures set forth above, the wide sole face provides high stability and a sense of ease when address is taken. The golf club head can not only decrease the probability of duffing, but also make the center of gravity deeper and lower because the overall shape is like a mallet patter head rather than a hollow wood-type head. Since a player is caused to make a putting-like stroke rather than a swing to be made with golf clubs other than the putter, the player can easily hit the ball at the sweet spot. Even in the case of off-spot shots, sufficient directional stability is attained by virtue of toe-heel balance, As a result, a carry and a run that are determined by the loft angle and fall within prescribed ranges are expected. The golf club set forth above in which the shaft is attached to the top blade of the head allows a player to make a putting-like stroke easily and hence to easily adjust the distance in a delicate manner. In addition, setting the head weight at 350 to 450 g allows a player to make a slow stroke and thereby obtain a subtle sense of distance, which prevents hands-adjusted bad shots as would be played with golf clubs having a lightweight, hollow wood-type head.

Problems solved by technology

However, because of their shape, these golf clubs do not allow a player to swing with the same feeling as he or she strokes with a putter.

Further, because of a hollow wood-type shape, the center of gravity of the head is deep and cannot be made as low as patter heads (additional reason: presence of the neck portion).

These factors make it difficult Lo hit the ball at the sweet spot and obtain a stable distance.

Since 2 to 3 yards are serious error in approach shot, amateur golfers unavoidably hit the ball by their own will and hence have difficulty obtaining a subtle sense of distance that is necessary for accurate approach shots.
