Abstract

A golf club 2 includes a head 4 , a shaft 6 , and a fixing member Fx 1 . The head 4 has a hosel part 4 h capable of swingably supporting the shaft 6 . The shaft 6 has a tip connecting part 6 t capable of being connected to the fixing member Fx 1 . The fixing member Fx 1 has a connector 12 capable of being connected to the shaft 6 , a first sliding member S 1 capable of engaging the connector 12 with a plurality of positions in a first direction D 1 , and a second sliding member S 2 capable of engaging the first sliding member S 1 with a plurality of positions in a second direction D 2 . A movement of the connector 12 in the first direction D 1 and a movement of the connector 12 in the second direction D 2 are independent of each other.

First claim

What is claimed is:

1. A golf club comprising a head, a shaft, and a fixing member for fixing the shaft,
wherein the head has a hosel part capable of swingably supporting the shaft;
the shaft has a tip connecting part capable of being connected to the fixing member;
the fixing member has a connector capable of being connected to the shaft, a first sliding member capable of engaging the connector with a plurality of positions in a first direction, and a second sliding member capable of engaging the first sliding member with a plurality of positions in a second direction; and
a movement of the connector in the first direction and a movement of the connector in the second direction are linearly perpendicular to each other.

2. The golf club according to claim 1 , wherein a lie angle can be changed by any one of the movement of the connector in the first direction and the movement of the connector in the second direction, and a loft angle can be changed by the other.

3. The golf club according to claim 1 , wherein the fixing member has a first indicating part indicating a position of the connector in the first direction; and
the first indicating part can be visually recognized from a sole surface side of the head.

4. The golf club according to claim 1 , wherein the fixing member has a second indicating part indicating a position of the connector in the second direction; and
the second indicating part can be visually recognized from a sole surface side of the head.

5. The golf club according to claim 1 , wherein the connector has a screw and a screw position fixing member;
the tip connecting part has a female screw part; and
the shaft is fixed to the head by screw combination of the screw with the female screw part.

6. The golf club according to claim 5 , wherein the screw position fixing member and the first sliding member can be engaged at the plurality of positions in the first direction.

7. The golf club according to claim 6 , wherein the engagement between the screw position fixing member and the first sliding member is fixed by an axial force of the screw combination.

8. The golf club according to claim 1 , further comprising an elastic member biasing the first sliding member in a direction in which the first sliding member is engaged with the second sliding member.

9. The golf club according to claim 8 , wherein the engagement between the first sliding member and the second sliding member is released by moving the first sliding member in a direction opposite to the biasing direction of the elastic member against an biasing force of the elastic member; and
the first sliding member can be moved in the second direction by releasing the engagement.

10. The golf club according to claim 1 , wherein engagement between the connector and the first sliding member is achieved by an uneven structure A;
engagement between the first sliding member and the second sliding member is achieved by an uneven structure B; and
an uneven overlapping depth in the uneven structure B is different from an uneven overlapping depth in the uneven structure A.

11. The golf club according to claim 1 , wherein the hosel part has a hosel hole; and
the hosel hole widens toward the lower part thereof in a portion into which the tip connecting part can be inserted.

12. The golf club according to claim 1 , wherein the hosel part has an end face; and
the end face can support an axial force acting on the tip connecting part.

13. The golf club according to claim 1 , further comprising an annular elastic body,
wherein the hosel part has an end face;
the tip connecting part has a protrusion surface;
the annular elastic body is disposed between the end face and the protrusion surface; and
a gap between the protrusion surface and the end face is filled by deformation of the annular elastic body in all adjusted angles.

14. The golf club according to claim 1 , wherein the tip connecting part has a projection curved surface part;
the hosel part has a recessed curved surface part; and
the projection curved surface part and the recessed curved surface part are brought into contact with each other.

15. The golf club according to claim 1 , wherein the tip connecting part has a rotation prevention projection part;
the hosel part has a rotation prevention recessed part; and
rotation prevention of the shaft is achieved by engagement between the rotation prevention projection part and the rotation prevention recessed part.

16. The golf club according to claim 2 , wherein the lie angle can be adjusted without substantially changing the loft angle.

17. The golf club according to claim 2 , wherein the loft angle can be adjusted without substantially changing the lie angle.
