Description

This invention relates to golf club parts, and in particular to a golf club head hosel angle adjustment mechanism and a golf club head having the golf club head hosel angle adjustment mechanism.

Typically, the angle of the golf club head is adjusted to suit the player's hitting habits.
That is, the angle of the club shaft relative to the golf club head is adjusted.
This allows the golf club head to have an appropriate loft angle (LOFT) or lie angle (LIE) when the player grips the club shaft, making it easier for the player to hit the ball along a predetermined trajectory.
When adjusting the angle of the club shaft, the golf club head is fixed and a wrench is used to move the hosel of the golf club head, thereby changing the relative angle between the hosel and the golf club head, thereby coupling the club shaft to the hosel and achieving the predetermined loft angle or lie angle described above.

In order to make the above and other objects, features and advantages of the present invention more apparent and understandable, the present invention will be described in detail below with reference to the embodiments and drawings.
In addition, parts marked with the same reference numerals in different drawings are regarded as the same parts, and the description thereof will be omitted.

As shown in FIG. 1, the embodiment of the hosel angle adjustment mechanism for a golf club head of the present invention includes a base body 1 and a fixing member 2, and the fixing member 2 is formed to be connected to one end of the base body 1.

The outer shape of the seat 1 shown in FIGS. 2 and 3 may be substantially cylindrical so as to be coupled with a hosel 31 of the golf club head 3 .
The seat body 1 can have a first end surface 1a and a second end surface 1b, the first end surface 1a and the second end surface 1b being located at two opposite ends of the seat body 1, respectively.
The first end surface 1a and the second end surface 1b may be two end surfaces parallel to each other.
The base 1 has a first axis O1 that passes through the first end surface 1a and the second end surface 1b and is perpendicular to the first end surface 1a and the second end surface 1b.

As shown in FIGS. 1 and 2, the base body 1 has a coupling groove 11, and a first end surface 1a of the base body 1 has an opening 12 communicating with the coupling groove 11.
Thereby, the seat 1 can be used to couple the club shaft T through the opening 12 to the coupling groove 11 .
In detail, the coupling groove 11 has a shape corresponding to the club shaft T, for example, the coupling groove 11 may be a groove in a cylindrical space, thereby allowing the club shaft T to be tightly coupled to the seat body 1.
The coupling groove 11 has a second axis O2, which passes through the groove bottom surface 13 and the opening 12 of the coupling groove 11, and the second axis O2 is perpendicular to the groove bottom surface 13.
It should be noted that the first axis O1 and the second axis O2 are not parallel to each other but intersect with each other so as to form an included angle θ between them.
That is, the coupling groove 11 is inclined relative to the base body 1 .
In this embodiment, the first axis O1 and the second axis O2 intersect with the groove bottom surface 13, and the included angle θ formed by the first axis O1 and the second axis O2 may be 1 to 2°.

The seat body 1 can have at least one positioning portion 14, and the at least one positioning portion 14 can prevent the seat body 1 from rotating within the hosel 31, thereby allowing the seat body 1 to be positioned within the hosel 31.
More specifically, at least one positioning portion 14 is located on the outer circumferential surface of the base body 1 so that the radial cross section of at least one positioning portion 14 of the base body 1 is formed as a non-circular shape.
As a result, at least one positioning portion 14 is engaged with the inner wall of the hosel 31, and the seat body 1 is prevented from rotating within the hosel 31 (details will be described later).
The at least one positioning portion 14 may be a convex rib, the at least one positioning portion 14 may extend in the direction of the first axis O1, the extension length of the at least one positioning portion 14 may be 5 to 10 mm, and the width of the at least one positioning portion 14 in the circumferential direction may be 1 to 4 mm.
In this embodiment, there are multiple positioning portions 14, and the multiple positioning portions 14 can be arranged at equal intervals in the circumferential direction on the outer circumferential surface of the base body 1, and the intervals between the positioning portions 14 in the circumferential direction may be 4 to 8 mm.

The fixing member 2 is used to fix the base 1 to a hosel 31 of the golf club head 3 .
The fixing member 2 may be a bolt, and the second end surface 1 b of the base body 1 may have a screw hole 15 so that the fixing member 2 can be coupled to the screw hole 15 .
Furthermore, the hosel 31 of the golf club head 3 has an opening 32 and a bottom hole 33, and the opening 32 of the hosel 31 is formed to face the bottom hole 33. The base body 1 can be inserted into the hosel 31 from the hosel opening 32, and the base body 1 can be fixed to the hosel 31 by inserting the fixing member 2 into the bottom hole 33 and connecting it to the screw hole 15.

In this embodiment, the hosel 31 may have a plurality of grooves 34 located on the inner circumferential surface of the hosel 31 so as to radially align at least one positioning portion 14 .
Each groove 34 may have a structure corresponding to at least one locating portion 14 such that the groove 34 couples with at least one locating portion 14 .
Therefore, the seat 1 can be positioned in the hosel 31 without rotation.
Furthermore, when there are a plurality of at least one positioning portions 14, each positioning portion 14 is coupled to each groove portion 34, thereby achieving a more excellent positioning effect.

As shown in Figures 2 and 3, when adjusting the angle using the angle adjustment mechanism of the hosel of the golf club head of the present invention, when the club shaft T is coupled to the coupling groove 11 of the base body 1 and the base body 1 and the hosel 31 are separated, when the base body 1 is rotated about the first axis O1, the second axis O2 of the coupling groove 11 will be inclined with respect to the first axis O1, so that the club shaft T will rotate eccentrically with the first axis O1 together with the rotation of the base body 1, and thus the angle of the club shaft T with respect to the golf club head 3 can be changed.
After the player adjusts the club shaft T to a predetermined angle relative to the golf club head 3 , the player can fix the seat 1 to the hosel 31 via the fixing member 2 .
Furthermore, by connecting at least one positioning portion 14 to one of the multiple groove portions 34, the position of the seat body 1 is determined in advance within the hosel 31, and the seat body 1 is fixed within the hosel 31 by the fixing member 2, so that it is possible to prevent the angle from being shifted due to rotation of the seat body 1 during the fixing operation using the fixing member 2.
Furthermore, the multiple grooves 34 may be numbered at different angles in the circumferential direction.
This allows the player to visually align at least one positioning portion 14 with a predetermined groove portion 34 and adjust the club shaft T to a predetermined angle, providing better convenience.

In summary, the golf club head hosel angle adjustment mechanism of the present invention has a second axis O2 of the coupling groove 11 that is inclined and angled with respect to the first axis O1, allowing the player to change the angle of the club shaft T relative to the golf club head 3 by rotating the seat 1, without moving the hosel 31 of the golf club head 3 or deforming the structure of the golf club head 3, thus avoiding damage to the golf club head 3 and improving the convenience of adjusting the angle.
