2. Description of the Related Art Golf clubs have woods and irons with different lofts (inclination of the face to be hit) with different elevation angles. However, the individual head weights of these clubs and their balance are determined by the user. It is customary to make your own adjustments according to your taste and skill, and heavyweight sheets are commercially available for this adjustment. This heavy sheet has an adhesive layer formed on the back surface of a thick lead tape,
A piece cut into a required size is attached to the outer surface of the head piece by utilizing the adhesive force of the adhesive layer.

However, when such a heavy sheet is attached to the outer surface of the head piece, the heads are likely to come into contact with each other during transportation of the club or the like to cause the heavy sheet to be displaced or peeled off. However, in terms of appearance, the heavy seats were ugly and visually unappealing.

Further, since the above-mentioned heavy sheet cannot be attached to the bottom surface, that is, the sole portion, which rubs the face portion against which the ball hits at the time of hitting the ball, that is, the sole portion, it is generally attached to the peripheral side surface excluding the face portion. However, from the viewpoint of increasing the head speed at the time of hitting the ball by the centrifugal force of the club and extending the flight distance of the ball, it is desirable that the club head has a low center of gravity. When it is attached to the peripheral side surface, the center of gravity of the club head rises, which deteriorates the hitting function.

If the concave portion provided in the sole is formed in a groove shape along the direction orthogonal to the face portion, the moving direction of the head and the groove direction of the concave portion coincide with each other when the sole surface is rubbed against the ground surface at the time of hitting the ball. Therefore, the sliding resistance is reduced, and the groove of the recessed portion causes the head to move in the desired front-back direction with the ball moving direction. Further, the weight balance can be finely adjusted in the front-rear direction by setting the front and rear positions of the weight sheet attachment position in the recess. Further, particularly in the case of metal wood, since the metal plate of the sole portion has ribs due to the groove-shaped recesses, the rib effect improves the strength of the head itself.

However, if there are two or more groove-shaped recesses provided on the sole, the weight balance in the left-right direction, that is, in the toe-heel direction can be adjusted by selecting the recesses to which the weight sheet is attached and by the difference in the number of the attached sheets. As a result, the strength of the metal wood due to the rib effect is further increased.

In a so-called round-sole head in which the sole portion has a medium-height mountain shape, if the plurality of groove-shaped recesses are formed separately on both sides of the top of the mountain-shape, these groove-shaped recesses make the most contact with the ground when hitting the ball. Since it is easily removed from the top, orthogonal contact between the surface of the adhered weight sheet and the ground is avoided, and contact with the lawn, etc. is weakened, and the weight sheet is slidably contacted with the ground surface of the sole part. Positional deviation and peeling are less likely to occur.

Further, there are two groove-shaped recesses in the head of the round sole, both recesses have a divergent shape with the face side first, and the top side edges of both recesses are orthogonal to the face portion. If the sole portion slides on the ground surface when hitting a ball, a side-direction edge of the parallel-orthogonal shape produces a movement direction regulation effect,
As a result of the resistance force due to the sliding contact between both side edges arranged in a V shape on the side far from the sole surface top of both recesses and the ground surface, the operation direction of the head is directed toward the midline direction of the opening angle of the both side edges, The action of guiding the moving direction of the head in the front-back direction is further increased.

The recess formed in the sole portion may have a depth such that the surface of the attached weight sheet is lower than the surface of the sole portion, but the depth is such that a plurality of weight sheets can be stacked. It is possible to increase the adjustment range of the head weight and its balance by setting.

In the golf club head having the above structure, the weight sheet (8) is attached to one or both of the pair of groove-shaped recesses (5) and (5) to adjust the weight, and both groove-shaped recesses ( 5) It is possible to adjust the weight balance in the left-right direction (toe / heel direction) by making a difference in the number of sheets of the weight sheet (8) attached to (5) (one may be 0), and If a sheet (8) smaller than the groove-shaped recess (5) is used, the weight balance in the front-rear direction can be finely adjusted by shifting the attaching position in the front-rear direction. If weight sheets (8) having different weights (thicknesses) are prepared, the weight and balance can be adjusted more finely. Moreover, since the center of gravity of the entire head is lowered by sticking the weight sheet (8), the flight distance of the ball is increased due to the increase of the centrifugal force at the time of hitting the ball.

Further, since the surface of the weight sheet (8) attached to the groove-shaped recesses (5) (5) is located lower than the surface of the sole portion (4), the club heads may come into contact with each other during transportation. Also, the contact of the weight sheet (8) itself is avoided, and in addition, since the groove-shaped recesses (5) and (5) are located on both sides of the top portion (4a) of the sole portion (4), the sole portion (4) is struck when the ball is hit. Even if the ground surface rubs, the force applied to the weight sheet (8) by sliding contact with the lawn is small, and the weight sheet (8) is less likely to be displaced or peeled off, and thus the adjusted weight and balance are less likely to get out of order. Top, appearance weight sheet (8)
There is almost no difference between the adhered state and the non-adhered state, and both look good. Further, by forming the groove-shaped recess (5), the sole portion (4)
Has a rib (4b) (see FIG. 2) on the inner surface side to increase the strength, and the head piece (1) as a whole has excellent strength.

Since both the groove-shaped recesses (5) and (5) are long and wide in the front-rear direction which is the moving direction of the head when hitting the ball, the resistance when the sole part rubs the ground surface is small. In addition, the side edges (5a) and (5a) on the top (4a) side are parallel straight lines along the front-rear direction, and the direction control effect and the other side edges (5b) and (5b) arranged in a V shape are provided. Due to the inward guidance effect, the movement of the head is guided in the desired front-back direction, the swing stability of the club at the time of hitting the ball is increased, and thus very good hitting characteristics are obtained.

The present invention can be similarly applied to a club head of metal wood or iron other than the round sole type, and can also be applied to a club head using a carbon face. Further, in the present invention, the inner surface shape of the head piece, the detailed structure of the connection structure with the club shaft, and the like can be variously modified in addition to the examples. The structure may be integrally formed.

According to the first aspect of the present invention, when adjusting the weight and balance of the head, the weight sheet for adjustment can be fitted into the concave portion of the outer surface of the head piece and attached. There is no risk that the seat will come into contact with other club heads during transportation, causing misalignment or peeling, and the weights and balances that have been adjusted can be maintained without distortion. A head can be provided.
