Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a golf club, and in particular,
It concerns the improvement of wood clubs.

[Conventional technology]

Conventionally, as a wood club, in order to form a sweet spot of the club in a wide area, it is known that a concave portion is provided in a sole portion and a heavy weight is filled in a toe heel portion of the concave portion. Then, a core for filling the heavy object was provided, the heavy object was filled in the core, and a sole plate was fitted and fixed. Therefore, although a wide spot of sweet spot can be expected with this device, the structure is complicated and the cost is high. Therefore, there is a technical problem to be solved in order to make the structure simple and contribute to cost reduction, and also to enable accurate addressing of the wood club.

[Means for solving problems]

In view of the above problems, the present invention has been proposed as a solution to the problem, and in a wood club, a concave portion is provided in a concave portion in the upper surface on the side opposite to the face surface of the head, and the concave portion is provided. The cross-shaped first display portion is provided, and when the wood club is subjected to a regular address, the second display portion formed to extend linearly with the first display portion is the first display portion. The present invention provides a golf club characterized in that the golf club is provided on the surface of the wood club head in the front and rear direction and on the face of the face on the extension line.

[Action]

A substantially cruciform first display portion is provided in a concave portion provided in a central portion of the surface of the wood club head opposite to the face surface, and the wood club head on the extension line of the first display portion is provided. The second display portion is also provided on the surface.
Moreover, when the address of the wood club is held in the correct posture, the first display portion and the second display portion may be extended linearly with the second display portion. To be visible to the player. However, in the left-right direction display section, the second display section displayed on the face side surface and the left-right direction display of the first display section formed in the concave portion are aligned, and the front and rear sides are formed on the club surface. The front and rear second display portions are formed so as to coincide with the first display portions on the front and rear straight line provided in the recess. Therefore, if the address attitude is not correct, for example, if the hook attitude or the head is tilted to the extreme, or if the slice attitude or the head is tilted to the rear, the front and rear postures described above are used. 1
The display and the second display do not match. Therefore, the player can know the incorrect address in the state where the first display unit and the second display unit do not match, and can correct his address until both display units match.
Further, the hand-up or hand-down address attitude can be recognized by the left and right display sections of the first display section and the second display section, and the address can be corrected until both sides match. it can.

Further, since the concave portion is provided with the first display portion in the concave portion on the surface of the wood club, it can be expected to have a wide area of the sweet spot of the wood club with a simple structure in view of the large formation. It became.

〔Example〕

Hereinafter, an embodiment of the present invention will be described in detail with reference to the attached drawings.

(1) is a wood club, and (2) shows its head.
(3) is the face side. Thus, a recess (4) is provided in the center of the surface of the head (2). This recess (4) is formed large in the center of the head (2) and has a face surface.
Although the concave portion (4) is recessed to reach the end surface on the side opposite to (3), it should not be limited to this. Further, a substantially cross-shaped first display portion (5) is provided on the flat surface portion (4a) of the concave portion (4). Then, the display portions (5a) (5a) (5a) before and after the first display portion (5)
A) and the left and right display portions (5b) and (5b) are formed in a substantially cross shape in the front-rear direction. Then, the front and rear display parts (6a) on the surface of the head (2) on the extension lines of the front and rear display parts (5a) and (5a) and the left and right display parts (5b) and (5b) of the first display part (5), respectively. ) (6a) and a second display section (5) composed of left and right display sections (6b). The display portions (6a) and (6a) before and after the second display portion (6) are different from the front and rear display portions (5a) and (5a) of the first display portion at the correct address. The display parts (5b) (5) on the left and right of the first display part (5) are aligned with each other on a straight line.
In contrast to b), the left and right display portions (6b) of the second display portion (6) are provided so as to be linearly aligned with each other at the correct address. As described above, since the first display portion (5) is formed on the flat surface portion (4a) of the concave portion (4), the horizontal position is different from that of the second display portion (6). To do. Therefore, for example, when addressing the hook posture, the forward leaning posture of the head (2) or the slice posture or the backward leaning posture of the head (2), the front and rear of the first display unit (5) and the second display unit (6) are addressed. Display (5
a) (5a) and (6a) (6a) do not match, and when the address is handdown or handup, the left and right display parts (5b) and (6b) do not match, and thus both It becomes possible to correct its own address and correct it to the desired posture or the desired posture until the display portions of are matched.

Further, since the first display portion (5) is largely provided in the central portion of the surface of the head (2) as described above, the face surface (3)
The wide area of the sweet spot can be obtained, and the structure can be formed by simply notching the head surface, which can contribute to cost reduction.

[Effect of device]

As described in detail in the above one embodiment, the present invention forms the wide area of the sweet spot of the wood club with a simple structure, and by using this structure, the address position is corrected by the user himself. This is a device that enables correction and contributes to cost reduction.
