[0004] Usually, this type of iron type club is disclosed in, for example, JP-A-63-57073 and JP-A-63-21.
As shown in Japanese Patent No. 6584, a structure in which a grip is fixed to a base portion of a shaft, a lower end portion of the shaft is fitted and fixed in a hole of a hosel portion, and a hosel portion and a club face portion are connected by a neck portion, is used. It is manufactured by forging or casting integrally with a material such as an iron-based material or a copper-based material.

In a conventional iron-type club, the back end of the club face portion is viewed smoothly in a plan view and smoothly continues to the hosel portion via the neck portion when viewed from the top (see the dashed line A in FIG. 2). The center of gravity is set on the club face part, especially on the slightly toe side, so that the club face part is square or slightly closed with respect to the ball at impact, so that the hitting force can be efficiently transmitted to the golf ball to achieve the desired The flight distance was secured.

However, in the conventional iron-type club, the club face portion is made to have a square or slightly closed impact in terms of shape, so that it is difficult for intermediate and advanced golfers who are familiar with golf technology. There was a problem that the club face portion was not stable at the time of addressing, and hooks and slices were easily generated when swinging.

[0007] In the conventional iron-type club toe-heel balance, the center of gravity of the club is set slightly on the toe side of the club face portion, so that the intermediate swing or the advanced golfer whose downswing speed is faster than that of a beginner. There is a problem that the toe side of the club face part is lowered, so that a 'toe down phenomenon' easily occurs, that is, a so-called 'difference' easily occurs.

The inventor of the present invention has made intensive studies to solve the above-mentioned problems, and as a result, contrary to the conventional common sense toe-heel balance, the back face shape of the club face portion has been changed to the hosel portion. When the thickness is increased at the back of the hosel part by extending the shape to a position passing through the center axis of the club face, the center of gravity of the club face part is at or near the intersection of diagonal lines passing through the face part, and the above problem is solved. The main part is to fit the lower end of the shaft 5 having the grip into the hole 30 of the hosel part 3 of the club head 1 while fixing the hosel part 3
And the club face portion 2 are integrally connected by a neck portion 4. In the iron-type golf club, the back surface 22 of the club face portion 2 passes through the central axis a of the hosel portion 3 in the front-rear direction while maintaining its shape. The club face 2 of the face (20)
The space between the heel end and hosel (3) extends in the front-rear direction

It is preferable that the shape of the back surface 22 of the club face portion 2 is performed by moving a part of the weight of the toe side B of the club head, that is, without changing the weight of the club head (see FIG. 4).

According to the present invention, the structure in which the back surface of the club face portion is substantially extended to the position passing through the center axis of the hosel portion in the front-rear direction while maintaining the shape of the club face portion and connected to the hosel portion is the conventional toe heel. In terms of balance, the design is completely out of common sense, but the center of gravity is located at or near the intersection of diagonal lines passing through the club face, resulting in an exquisite balance and a 70% reduction in toe return when hit. Therefore, the design can eliminate the cause of the hooking. Therefore, the driving can be performed with confidence. Further, it is possible to increase the thickness of the blade by design, and it becomes possible to strike a ball with a good hold.

Further, as a result of the center of gravity being located at or substantially at the intersection of the diagonal lines passing through the club face portion, unlike conventional irons, the toe-down that tends to occur at impact can be eliminated (see FIG. 6). The weight is distributed to escape, and mistakes due to 'pretend' can be prevented.

Further, if the center of gravity is located at or substantially at the intersection of diagonal lines passing through the club face portion, and the club face portion 2 is designed to be slightly open at about 1.5 ° at the time of addressing, the conventional structure is obtained. In the club, the head is easy to return immediately after impact and easy to get caught (Fig. 7, left figure), but in the present invention, the impact is slightly open, the square is formed immediately after that, and the head returns little by little after that, The ball makes it easier to delineate the ideal trajectory of the hydro (see FIG. 7 comparison).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to specific examples shown in the drawings. 1 to 3 show an iron type golf club according to an embodiment of the present invention. In the drawing, a club head 1 is formed in a structure in which a club face portion 2 and a hosel portion 3 are integrally connected, and the club head 1 is integrally formed by forging or casting using an iron-based material or a copper-based material.

Further, the club face portion 2 has a face 20 and a sole 2 which are opened 1.5 ° from the square.
1 and a back side (back side) 22, which is substantially extended to a position passing through the center axis a of the hosel portion 3 in the front-rear direction while maintaining the back shape as shown in FIG. Through , ie almost in the front-back direction
It is formed in a shape connected to the hosel portion 3 by an extending connection portion , and the thickness is increased on the back surface of the hosel portion 3, and thus the neck portion is much smaller than the shape of the conventional club head. That is, the conventional neck portion 4 has been substantially removed. As a result, as shown in FIG. 5, the center of gravity of the club head is located at or near the intersection of diagonal lines of the face portion.

Therefore, when the club face is addressed with the club, the club face 2 is slightly open even if the club face 2 is held square. In addition, club face part 2
Is extended to a position passing through the center axis a of the hosel portion 3, and a portion corresponding to the neck portion 4 in the conventional club has a bulging shape, and the center of gravity of the club face portion 2 is located at the intersection of diagonal lines. Then, the club face portion 2 is stabilized slightly on the heel side, and when the club is swung from that state, the golfer can easily impact the club face portion 2 on the ball squarely, and straighten without hooking or slicing the ball. Can be skipped.

Also, even if an intermediate or advanced player makes a downswing at a high speed, the rigidity around the hosel portion 3 is high, and the center of gravity of the club face portion 2 is located at the intersection of the diagonal lines and is set slightly on the heel side. As a result, the toe-down phenomenon hardly occurs, and as a result, the so-called 'squatting' does not occur, and the impact can be made smoothly.
