Abstract

This golf club includes a shaft, a golf club head, a first adapter, a second adapter, and a fixing member that fixes the first adapter in an interior space of a hosel portion. The shaft is configured to be coupled with an inclination relative to the coupling portion of the first adapter, and the first adapter is configured to be coupled with an inclination relative to the second adapter.

First claim

The invention claimed is:

1. A golf club comprising:
a shaft;
a golf club head having a hosel portion and an opening portion that is formed on a side opposite to the hosel portion and is in communication with an interior space of the hosel portion, the interior space being open at a shaft attachment hole of the hosel portion, and the golf club head having a hosel coupling portion in a vicinity of an opening of the attachment hole;
a first adapter that has a first end portion and a second end portion, the first adapter having a shaft receiving recessed portion to which the shaft is to be fixed and that is open on a first end portion side, the first end portion having a coupling portion, and the second end portion being accommodated in the interior space of the hosel portion through the attachment hole;
a second adapter that has a first end portion and a second end portion at respective ends along a first axis and has a through-hole through which the first adapter passes, the first end portion having a first coupling portion that is to be detachably coupled to the coupling portion of the first adapter, and the second end portion having a second coupling portion that is to be detachably coupled to the hosel coupling portion; and
a fixing member that detachably fixes the first adapter in the interior space of the hosel portion,
wherein

the shaft is configured to be coupled with an inclination relative to the coupling portion of the first adapter,
the first adapter is configured to be coupled with an inclination relative to the second adapter,
the coupling portion of the first adapter and the first coupling portion of the second adapter can be coupled in a plurality of rotation positions about an axis,
the second coupling portion of the second adapter and the hosel coupling portion can be coupled in a plurality of rotation position about an axis,
the coupling portion of the first adapter and the first coupling portion of the second adapter are coupled outside the hosel portion, and
the second adapter has the first end portion and the second end portion at respective ends along the first axis and is formed with a tubular shape along the first axis, and the through-hole of the second adapter is formed along a second axis that intersects the first axis.

2. The golf club according to claim 1 ,
wherein the first adapter has the first end portion and the second end portion at respective ends along the first axis and is formed with a tubular shape along the first axis, and the shaft receiving recessed portion extends along a second axis that intersects the first axis.

3. The golf club according to claim 2 , wherein the second adapter is formed with a ring shape, and is arranged along the attachment hole such that at least a portion is exposed to the outside.

4. The golf club according to claim 3 ,
wherein the coupling portion of the first adapter is formed by a flange portion that projects radially outward, and
the flange portion is coupled to the first coupling portion of the second adapter.

5. The golf club according to claim 4 ,
wherein a protrusion/recession portion is formed on the flange portion of the first adapter along a circumferential direction, and
a protrusion/recession portion that engages with the protrusion/recession portion of the flange portion is formed on the first coupling portion of the second adapter so as to be visible from the outside.

6. The golf club according to claim 5 ,
wherein a protrusion/recession portion that extends along a circumferential direction of the attachment hole is formed on the hosel coupling portion, and
a protrusion/recession portion that engages with the protrusion/recession portion of the hosel coupling portion is formed on the second coupling portion of the second adapter.

7. The golf club according to claim 2 ,
wherein the coupling portion of the first adapter is formed by a flange portion that projects radially outward, and
the flange portion is coupled to the first coupling portion of the second adapter.

8. The golf club according to claim 1 , wherein the second adapter is formed with a ring shape, and is arranged along the attachment hole such that at least a portion is exposed to the outside.

9. The golf club according to claim 8 ,
wherein the coupling portion of the first adapter is formed by a flange portion that projects radially outward, and
the flange portion is coupled to the first coupling portion of the second adapter.

10. The golf club according to claim 1 ,
wherein the coupling portion of the first adapter is formed by a flange portion that projects radially outward, and
the flange portion is coupled to the first coupling portion of the second adapter.

11. The golf club according to claim 10 ,
wherein a protrusion/recession portion is formed on the flange portion of the first adapter along a circumferential direction, and
a protrusion/recession portion that engages with the protrusion/recession portion of the flange portion is formed on the first coupling portion of the second adapter so as to be visible from the outside.

12. The golf club according to claim 1 ,
wherein a protrusion/recession portion that extends along a circumferential direction of the attachment hole is formed on the hosel coupling portion, and
a protrusion/recession portion that engages with the protrusion/recession portion of the hosel coupling portion is formed on the second coupling portion of the second adapter.
