Used for side. Further, “front” is used on the toe side of the head, and “rear” is used on the heel side, and “front-back direction” is a direction connecting the toe and the heel.

  As shown in FIGS. 1 and 2, the golf club 10 according to the present embodiment includes a shaft S and a head H that includes a hosel 16 that receives the tip side of the shaft S and communicates with the sole surface 13. A lie angle adjusting mechanism 20 provided between the shaft S and the hosel 16 is provided.

  The head H is formed in a hollow with a crown surface 11, a side surface 12, a sole surface 13 and a face surface 14. The hosel 16 is formed from the heel side of the crown surface 11 toward the sole surface 13, and a pair of notch portions 17 having a substantially V shape are circumferentially formed at the upper end portion thereof as shown in FIG. 3. It is formed with an interval of 180 degrees. The hosel 16 has a circular inner peripheral shape at the upper end, and the length in the front-rear direction is relatively longer than the length in the left-right direction (the direction perpendicular to the paper surface in FIG. 2) as it goes downward (sole side). An inner flange portion 16B that forms a hosel bottom portion that forms a long hole 16A in the front-rear direction is formed on the inner surface thereof.

  The lie angle adjusting mechanism 20 is attached to the distal end side of the shaft S and inserted into the hosel 16, and is inserted into the hosel 16 side from the sole surface 13 side, and the sleeve 21 is inserted into the hosel 16. The lie angle can be adjusted by shifting the sleeve connecting position by the connecting means 23 in the front-rear direction.

  As shown in FIGS. 3A and 3B, the sleeve 21 has a bottomed cylindrical shape with an open upper end, and a female screw 25 is formed at the center of the bottom. A tapered surface portion 26 whose diameter increases downward is formed at the upper portion of the sleeve 21, and a pair of raised surface portions 28 having an outer peripheral edge 28 </ b> A along a substantially semicircular arc-shaped locus at the lower end of the tapered surface portion 26. Are continuously provided at positions spaced apart by 180 degrees in the circumferential direction of the sleeve 21. The raised surface portion 28 is located in the cutout portion 17 of the hosel 16, and its outer peripheral edge makes point contact with the forming edge of the cutout portion 17 at two front and rear positions, whereby the shaft S is parallel to the paper surface in FIG. It can be rotated in the plane.

  The connecting means 23 includes a receiving member 30 having a through hole 31 and a bolt 33 that is inserted into the through hole 31 and can be screwed into a female screw 25 formed at the tip of the sleeve 21. As shown in FIG. 2 (B), the receiving member 30 has a plate shape or a piece shape in which the planar shape is provided in a substantially elliptical shape, and is provided in a shape provided with a step portion 35 on the outer periphery of the intermediate portion in the thickness direction. It has been. The step portion 35 has an outer shape that is seated on the lower surface side of the inner flange portion 16B, thereby restricting the insertion limit of the receiving member 30. The through hole 31 is formed at a position where the center is shifted in the front-rear direction with respect to the center of the length of the receiving member 30 in the front-rear direction. This “deviation” can be set arbitrarily.

  In the present embodiment, as shown in FIGS. 4A to 4C, the first to third receiving members having different “deviation” amounts described above are illustrated. These receiving members 30 are formed so that the positions where the through holes 31 are formed are shifted in the front-rear direction of the receiving member 30, and the lie angle when the front-rear direction of the receiving member 30 is changed according to the amount of shift. Printed on the outside. More specifically, when the through hole 31 of the receiving member 30 in FIG. 4A is arranged so as to be positioned on the heel side, the lie angle is 63 degrees, and when the front-rear direction is reversed, the lie angle Is 45 degrees. In a similar manner, the receiving member in FIG. 4B can be adjusted to 55 degrees and 53 degrees, and the receiving member 30 in FIG. 4C can be adjusted to 61 degrees and 47 degrees.

To release the mutual connection between the bolt 33 and the tip of the sleeve 21. Note that the receiving member 30 in FIG. 2 (B) is a type in which the through-hole 31 is shifted somewhat rearward from the center in the front-rear direction, and is similar to the receiving member 30 shown in FIG. 4 (B). .

  Next, the front-rear direction of the receiving member 30 is reversed by 180 degrees, and the bolt 33 is connected to the sleeve 21 again in this state. At this time, since the receiving member 30 has moved forward from the initial position of the through-hole 31, as shown in FIG. 5, the connection position of the bolt 33 is also shifted forward, resulting in an initial lie angle. Therefore, the inclination of the shaft S is adjusted in the direction in which the lie angle becomes smaller than the pair.

  Therefore, according to the present embodiment, the user can adjust the lie angle according to the formation position of the through hole 31 formed in the receiving member 30 by changing the front-rear direction of the receiving member 30. Therefore, various lie angle adjustments can be made by preparing different receiving members 30.

That is, although the present invention has been particularly shown and described with respect to specific embodiments, it should be understood that the present invention is not limited to the embodiments described above without departing from the scope of the technical idea and object of the invention. The trader can make various changes.

  For example, in the above-described embodiment, the lie angle can be adjusted by changing the front-rear direction of the receiving member 30, but the present invention is not limited to this, and as shown in FIG. A hosel bottom portion 40 having a slot hole 41 directed in the front-rear direction is formed, and a receiving member 42 movable in the front-rear direction is provided on the lower surface side of the hosel bottom portion 40, and a bolt 33 penetrating the receiving member 42 is provided. It is also possible to adopt a configuration that is screwed into the shaft S side. At this time, angle adjusting grooves 40A and 42A as a plurality of saw blade-like meshing structure portions extending in a direction orthogonal to the paper surface in FIG. It is possible to adjust the angle by forming and shifting the meshing positions of these grooves one by one forward or backward.

  Further, instead of the through hole 31 formed in the receiving member, a slot hole directed in the front-rear direction may be formed, and the lie angle may be adjusted by changing the insertion position of the bolt in the slot hole. .

  Further, a configuration is also conceivable in which a bolt protruding from the tip of the sleeve 21 is provided as the connecting means, the bolt is inserted into the receiving member 30, and a nut member or the like is tightened on the tip side.

In addition, the target club of the present invention is not limited to a driver, and can be applied to fairway woods and utilities, and does not prevent application to iron golf clubs.
In short, the present invention suffices if the configuration can adjust the lie angle of the golf club.
