[First embodiment]
<Golf club>
1 and 2 show a golf club according to an embodiment of the present invention. The golf club of this embodiment includes a golf club head 1 and a shaft 50 attached to the golf club head. The shaft 50 is not particularly limited, and a conventionally known shaft 50 can be employed.

<Golf club head>
As shown in FIGS. 1 and 2, the golf club head 1 includes a head body 2 that is attached to the shaft 50 as described above, and two weights 40 that can be attached to the head body so that their fixed positions can be changed. Equipped with

(Head body)
The head body 2 is formed with a rail portion 11 on which a weight 40 can slide. The head body 2 includes a face portion (ball hitting surface) 3, a sole portion (bottom surface) 4, a crown portion (upper surface) 5, and a hosel portion 7 having a shaft hole 6 into which a shaft 50 is inserted and fixed. A rail portion 11 is formed in the sole portion 4 of the head body 2, as shown in FIG.

The rail portion 11 is configured such that the weight 40 is slidably engaged therewith, and the weight 40 can be fixed at any position on the rail portion 11.

As shown in FIG. 2, the rail portion 11 is formed into an annular structure around which the weight 40 can go around.

The rail portion 11 is formed in a shape along the outer edge of the crown portion 5 in a plan view, and is formed in a substantially elliptical shape. Thereby, the weight can be placed at a position close to the outer edge along the shape of the golf club. In addition, the substantially elliptical shape means a shape in which the rail portion 11 does not have a corner portion (for example, a portion bent at a right angle). The rail portion 11 is formed into a groove shape with a concave cross section so that an engaging piece portion 40b of a weight 40, which will be described later, is engaged with the rail portion 11. Note that various engagement structures can be used for the engagement structure between the rail portion and the weight.

<Weight>
The weight 40 is a member that is slidably and fixably provided on the rail portion 11. Two weights 40 are provided on the rail portion 11. The weight 40 includes a main body portion 40a, an engaging piece portion 40b that protrudes from both sides of the main body portion 40a so as to be able to engage with each engaging groove 13 on both side surfaces 11b of the rail portion 11, and a main body portion 40a. and a fixing part 40c for fixing it to the rail part 11.

The main body portion 40a is provided so as to be slidable on both side surfaces 11b of the rail portion 11. A screw hole is formed in the main body portion 40a, through which the fixing portion 40c can be screwed.

The fixing portion 40c is constituted by, for example, a screw (male screw) having a flat portion at the tip. The fixing portion 40c is formed so as to be threaded into and penetrate the screw hole of the main body portion 40a. When this fixing part 40c is screwed in, its tip presses the bottom surface part 11a of the rail part 11, and by this pressing, each engagement piece part 40b is fixed to each engagement part 31b (the weight 40 is (fixed to the rail portion 11). Note that various structures can be used for fixing the weights to the rail portion.

It is preferable that each weight 40 is formed with a specific gravity larger than that of the head main body 2. Specifically, it is preferable that the weight 40 is made of a material having a specific gravity of 8 or more. Since the specific gravity of the weight 40 is greater than the specific gravity of the head main body 2 in this manner, the change in the center of gravity when the fixed position of the weight 40 is changed can be made larger.

The masses of the two weights 40 can be selected from various values, and they can both have the same mass, but it is preferable that the masses of the two weights 40 are different, which allows for various adjustments according to the player's preferences. becomes easier.

In the case where the two weights 40 have different masses, the weight 40 with the larger mass is preferably 10 g or more and 25 g or less.

Further, the weight 40 having a small mass is preferably 5 g or more and 15 g or less.

The difference in mass between the two weights 40 is preferably more than 0 g and less than 10 g.

The total mass of the two weights 40 is preferably 10 g or more and 30 g or less.

<Filling member>
The golf club head 1 further includes a filling member (not shown) that fills a region of the rail portion 11 where the weight 40 is not attached, and it is preferable that the mass of the filling member is smaller than the mass of the weight 40. Further, it is preferable that the specific gravity of the filling member is less than or equal to the specific gravity of the head main body 2. For example, when the material for forming the head body 2 is titanium, examples of the material for forming such a filling member include resin, magnesium, aluminum, etc. in addition to titanium.

By filling the region of the rail portion 11 where the weight 40 is not attached with the first filling member, it is possible to suppress sand, dirt, etc. from entering the rail portion 11 from the external environment. Furthermore, since the first filling material is lighter than the weight 40, the influence of the first filling material on the moment of inertia can be reduced.

Dimensions such as length, width, and depth of the rail portion 11 are not particularly limited and may be set appropriately. For example, the dimensions of the rail portion 11 may be appropriately set so as to obtain a desired amount of change in the center of gravity angle.

<Advantages>
In this golf club, by sliding the rail portion 11 and changing the fixed position of the weight 40, the trajectory of the ball can be easily adjusted to approach the trajectory intended by the player. For example, by moving the weight 40 toward the ball hitting surface, a trajectory with low launch and low spin can be obtained. Furthermore, by moving the weight 40 to the opposite side of the ball hitting surface, a trajectory with high launch and high spin can be obtained. Furthermore, by moving the weight 40 to the shaft 50 side, it becomes easier to turn the head and hit a draw. By moving the weight 40 to the opposite side of the shaft 50, the moment of inertia can be reduced and operability can be improved.

Since the golf club includes two weights 40, various adjustments can be made, thereby making it easier to make adjustments to bring the trajectory closer to the player's intended trajectory.

Furthermore, since the rail portion 11 of the golf club has an annular structure, the positional relationship between the two weights 40 can be easily changed. In other words, if the rail is a single line without an annular structure, the fixed position of one weight will be restricted by the other weight (specifically, the weight on the shaft side will exceed the weight on the other side). (cannot be moved to the opposite side of the shaft). On the other hand, in a rail portion having an annular structure, for example, a weight on the shaft portion side can be moved to the opposite side of the shaft portion via a route where the other weight does not exist. Note that a T-shaped rail structure with a branch part (detour part) is also possible, but even in this case, when moving one weight, it is necessary to move the other weight to the branch part. , the work of changing the position of the weight becomes complicated.

Furthermore, since the two (plural) weights 40 of the golf club have different masses, various further adjustments can be made, thereby making it easier to make adjustments to bring the trajectory closer to the player's intended trajectory. . In particular, since the rail portion 11 of the golf club has an annular structure, the positional relationship between the two weights having different masses can be easily changed as described above.

[Other embodiments]
The embodiments described above do not limit the configuration of the present invention. Therefore, in the embodiment, it is possible to omit, replace, or add components of each part of the embodiment based on the description in this specification and common general knowledge, and all of these are interpreted as falling within the scope of the present invention. Should.

For example, in the embodiment described above, a case has been described in which the weight 40 can be moved without falling off the rail part 11 by engaging each of the engagement grooves 13 of the rail part 11 and each of the engagement pieces 40b of the weight 40. The method for movably attaching the weight 40 to the rail portion 11 is not particularly limited to the above embodiment. Furthermore, the method for fixing the weight 40 to any fixed position on the rail portion 11 is not particularly limited.

Further, in the embodiment described above, a device including two weights 40 has been described, but a device including only one weight may be used. However, it is preferable that the golf club is equipped with a plurality of weights (including three or more weights), which allows various adjustments to be made and makes it easier to make adjustments to bring the trajectory closer to the player's intended trajectory. can.

In the embodiment described above, the rail portion 11 has a substantially elliptical shape as shown in FIG. 2, but as shown in FIG. The part on the opposite side of the hitting surface may have a shape such that the central portion is close to the hitting surface. Furthermore, as shown in FIG. 3, the rail portion 11 may have a corner portion.

Furthermore, in the embodiment described above, the rail portion 11 has been described as having only an annular structure, but the rail portion 11 may have a structure having an annular structure and a branch portion having an end. Further, the rail portion may have two annular structures, for example, in a figure-eight shape.

Although the case where the club head is attached to the shaft has been described, the golf club head only needs to be attachable to the shaft, and may be in a state before being attached.

Furthermore, although a case has been described in which the rail portion to which the weight is attached is provided in the sole portion, the present invention is not limited thereto. For example, as shown in FIG. 4, a rail portion 11 may be provided on the crown portion 5. Furthermore, rail portions may be provided on both the sole portion and the crown portion.

Furthermore, in the embodiment described above, the rail portion has a concave shape and the weight has an engaging piece portion that engages with the rail portion, but a convex portion is formed on the rail portion and the weight is engaged with the convex portion. The weight may have a matching groove. In addition, by forming a convex part on the rail part, and the weight being made up of a pair of divided bodies that can be divided into upper and lower parts, which are integrated by a screw (for example, a screw constituting the fixing part 40c), the convex part It is also possible to adopt a structure in which the parts are sandwiched from above and below.

The golf club head and golf club according to the present invention can adjust the trajectory of a hit ball so that it approaches the trajectory intended by the player. Therefore, these can be suitably used as various golf club heads and golf clubs with excellent operability.
