Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to heads for drivers, spoons, and other golf clubs.

[Conventional technology]

Conventional golf club heads either have a hole in the approximate center of the head and fill it with a weight such as lead to fix the sole grade, or as shown in FIG.
A recess was provided in the approximate center of the sole plate b, which was fixed to the sole plate, to store a weight such as lead, and a lid C was removably attached to the opening of the recess, so by changing the weight, the head The weight of a can be adjusted to be heavier or lighter, but the weight distribution will be approximately at the center of the head.

[Problem that the invention seeks to solve]

However, depending on the golfer, there are those who want to add weight to the face d, those who want to add weight to the rear e of the face, and those who want to add weight to the toe r side or heel g side, so the former In the case of 2 ace d, the method of adjusting the weighting position is to remove the sole plate b, provide a hole near the face d, and fill it with weight. In addition, in the case of the rear e of head a or the toe f1 heel g side, a metal piece is attached to the periphery of head a, but this method of providing a hole reduces the strength. Repeated blows tend to cause cracks, and the method of attaching metal pieces not only exposes them to the outside and makes them look unsightly, but also causes problems such as sometimes causing the parts to go out of order.

Further, in the latter case, there is a problem that the balance of the swing weight cannot be adjusted.

The present invention attempts to solve the above-mentioned problems by dividing the sole plate into a plurality of parts and forming them so that they can be attached to and removed from each other.
At least one sole plate is fixed to the head body and various adjustment mechanisms are provided in the spaces between each sole plate, so that the weight, balance, and center of gravity of the head can be adjusted even when the other sole plate is removed. The objective is to provide a club head in which the following can be easily adjusted individually or in combination.

[Means for solving problems]

That is, in the present invention, the sole plate of the head is divided into a plurality of parts so that they can be attached and detached from each other, and a space is provided between each sole plate, and the weight and balance are individually or combinedly provided in this space. The above problem was solved by providing various adjustable adjustment mechanisms.

〔Example〕

Hereinafter, the embodiments of the present invention will be explained in detail based on the drawings showing the embodiments.

The void space 5 is formed.

As a means for attaching and detaching the eleventh second sole plate 3a13b, a female screw 6 and a male screw 7 are provided on the inner peripheral surface of the recess 3c and the outer peripheral surface of the second sole plate 3b, respectively, as shown in the illustrated example. It is possible to use a screw means such as a screw or a machine screw, etc.

Further, the second sole plate 3b is not limited to the disk shape shown in the illustrated example, but may be any other polygon, any arbitrarily deformed shape, or the same shape as the first sole plate 3a.

Further, in the space 5, various adjustment mechanisms 8 are provided which can adjust the weight, swing weight, and depth of the center of gravity of the head l individually or in combination.

In the embodiment shown in FIGS. 1 and 2, the adjustment mechanism 8 has a plurality of weight storage recesses 8a, 8b in the space 5, that is, at the bottom of the first sole plate 3a.
, 8c are recessed at approximately equal intervals in the circumferential direction, and each of the storage recesses 8a
A weight 8d made of a lead plate or the like is formed so as to be able to be arbitrarily stored therein. In addition, a lid 9 is removably attached to the opening of each of the storage recesses 8a, for example, by means of screws, etc., to prevent the stored weights 8d from moving.

In this way, the weight of the head 1 can be adjusted in a balanced state by storing the ways (8d) of the same weight in each of the storage recesses 8a, 8b, 8c, and the weight of the head 1 can be adjusted in a balanced state.・Since the way) 8d can be adjusted by moving in the vertical direction of the head l, the depth of the center of gravity can be adjusted by adjusting the movement of the way) 8d in the vertical direction of the head 1. Also, weights 9 of different weights are stored in each storage recess 8a.
Furthermore, it is possible to adjust the balance of the swing weight by storing a weight 9 of a desired weight in the storage recess 8a on the side to which the weight is to be applied.

The adjustment mechanism 8 shown in FIGS. 3 and 4 is located on the rear side 1a of the head 1 of the first sole plate 3a, and forms a storage recess 8a with a lid 9. A plurality of screw holes 8e are provided at equal intervals from the 1b side to the heel IC side, and the weights 8f are formed in the screw holes 8e so that they can be detachably attached using screws 8g.

In this way, the desired weight of the weight (Way) 8d is placed in the storage recess 8a.
At the same time, the weight of the head l, the depth of the center of gravity, and the swing balance can be adjusted arbitrarily by selecting each screw hole 8e arbitrarily and attaching a weight 8f of a desired weight with a screw 8g. .

The adjustment mechanism 8 shown in FIGS. 5 and 6 has a storage recess 8a with a lid 9 on the rear Ia side of the head 1 of the first sole play 3a
At the same time, a serration shaft 8h is provided at the bottom of the first sole plate 3a and on the face ld side of the head l.
