Abstract
Provided is a golf club that allows for adjustment of the swing balance in relation to the whole golf club. A golf club head in one embodiment includes a club head and a grip. The club head has a sole portion provided with one or more attachment recesses to which weight attachment members with different weights are attachable, and the grip is provided with an attachment recess to which the weight attachment members with different weights are attachable. The weight attachment members with different weights are interchangeable between the one or more attachment recesses of the club head and between the one or more attachment recesses of the club head and the attachment recess of the grip.
Description
- The present application is a National Stage of International Application No. PCT/JP2020/025829 filed on Jul. 1, 2020, which claims priority to and the benefit of Japanese Patent Application No. 2019-235528, filed on Dec. 26, 2019, the contents of which are incorporated herein by reference in their entirety.
- The present disclosure relates to a golf club with a golf club head.
- Techniques for attaching a weight to a golf club head have been proposed so far to adjust the weight and weight balance of the golf club head. For example, JP 11-9742 A discloses a golf club head in which a plurality of weight attachment portions are provided on the sole portion of the club head body along a direction substantially orthogonal to the hitting surface, and weight adjustment members of appropriate weights and sizes are selectively attached to the weight attachment portions.
- In addition, techniques for attaching a balance weight to a golf club have also been proposed to increase the swing speed of the golf club. For example, JP 3052898 U discloses a golf club provided with a balance weight at the grip end of the golf club.

golf club 1 according to one embodiment of the present disclosure will be described with reference toFIG. 1 . In thegolf club 1 according to one embodiment of the present disclosure, the one or more attachment recesses 12 of theclub head 10 are located within 200 mm of an entire length L of thegolf club 1 from the edge (end) of theclub head 10 or from theclub head 10 side. - In addition, in the
golf club 1 according to one embodiment of the present disclosure, the one or more attachment recesses 12 of theclub head 10 are located within 25% of the entire length L of thegolf club 1 as viewed from the edge (end) of theclub head 10 or from theclub head 10 side. - Furthermore, in the
golf club 1 according to one embodiment of the present disclosure, the attachment recess 31 of thegrip 30 is located within 350 mm of the entire length L of thegolf club 1 from the edge (end) of thegrip 30 or from thegrip 30 side. - Moreover, in the
golf club 1 according to one embodiment of the present disclosure, the attachment recess 31 of thegrip 30 is located within 50% of the entire length L of thegolf club 1 as viewed from the edge (end) of thegrip 30 or from thegrip 30 side. - The
golf club 1 according to one embodiment of the present disclosure allows for not only adjustment of the weight balance of the golf club head and the counterbalance of the golf club grip, but also more accurate adjustment of the swing balance in relation to the whole golf club. - Referring next to
FIG. 4 , there is shown an example of theweight attachment members 11. In order to use theweight attachment members 11 with different weights as described above, theweight attachment members 11 with various weights can be formed using different materials, for example. Examples of materials of theweight attachment members 11 can include, but are not limited to, an aluminum alloy, stainless steel, a titanium alloy, and a tungsten alloy. More specifically, the attachment members with different weights can be exemplified by a weight attachment member 11 a having a weight of 3 g, a weight attachment member 11 b having a weight of 4 g, a weight attachment member 11 c having a weight of 7 g, and a weight attachment member 11 d having a weight of 6 g, which will be further described below. - As one aspect, the
golf club 1 according to one embodiment of the present disclosure may be configured by using the weight attachment members 11 a, 11 b, and 11 c for theclub head 10 and the weight attachment member 11 d for thegrip 30. In this case, the moment of inertia of the club is 2.9 million (S.B is C8.5). In such an aspect, it is possible to form a golf club whose swing balance is advantageous for users with a head speed (HS) of about 44 m/s to have ease of swing which ensures maximum performance of carry distance and direction control. - As another aspect, the
golf club 1 according to one embodiment of the present disclosure may be configured by using the weight attachment members 11 b, 11 c, and 11 d for theclub head 10 and the weight attachment member 11 a for thegrip 30. In this case, the moment of inertia of the club is 2.95 million (S.B is D1.4). In such an aspect, it is possible to form a golf club whose swing balance is advantageous for users with a head speed (HS) of about 47 m/s to have ease of swing which ensures maximum performance of carry distance and direction control. - As another aspect, the
golf club 1 according to one embodiment of the present disclosure may be configured by using the weight attachment members 11 a, 11 c, and 11 d for theclub head 10 and the weight attachment member 11 b for thegrip 30. In this case, the moment of inertia of the club is 2.93 million (S.B is D0.4). In such an aspect, it is possible to form a golf club whose swing balance is advantageous for users with a head speed (HS) of about 46 m/s to have ease of swing which ensures maximum performance of carry distance and direction control. - As still another aspect, the
golf club 1 according to one embodiment of the present disclosure may be configured by using the weight attachment members 11 a, 11 b, and 11 d for theclub head 10 and the weight attachment member 11 c for thegrip 30. In this case, the moment of inertia of the club is 2.87 million (S.B is C7.5). In such an aspect, it is possible to form a golf club whose swing balance is advantageous for users with a head speed (HS) of about 42 m/s to have ease of swing which ensures maximum performance of carry distance and direction control. - As described above, the
golf club 1 according to one embodiment of the present disclosure allows for more accurate adjustment of the swing balance in relation to the whole golf club, not to a part of the golf club head or the grip, without changing the weight of the whole golf club. - The dimensions, materials, and arrangements of the components described herein are not limited to those explicitly described in the embodiments. These components may be modified to have any dimensions, materials, and arrangements that may fall within the scope of the present disclosure.
