Description

  The present invention relates to a golf club, and more particularly to a golf club that can change various characteristics required for a shaft, such as length and rigidity, by exchanging a grip member.

The golf club includes a head and a shaft connected to the head. A grip serving as a region for gripping the shaft is attached to the butt side of the shaft.
The golf club shaft has various characteristics such that the length affects the flight distance, and the hardness (rigidity) affects the directionality of the ball and the swinging feeling. Therefore, shafts that are individualized according to their characteristics such as length, hardness, and weight are commercially available as options different from golf clubs.
Many users usually use the shafts that make up the golf club at the time of sale, so if you want to change the characteristics, it is actually possible to change the shaft (reshaft). It is.

  Patent Document 1 discloses a shaft attachment / detachment structure that can accommodate a reshaft, and Patent Document 2 proposes a configuration that can change the overall length of the shaft.

The golf club described in Patent Document 1 can set the golf club corresponding to the user's request by the reshaft. However, since the entire shaft is replaced, it becomes very expensive and has a large economic burden. . In addition, since the mechanism for attaching and detaching the shaft is provided on the head side, the weight of the head becomes heavier, causing the disadvantage that the degree of freedom in designing the golf club balance and various functions is reduced.
Further, in Patent Document 2, the length can be changed by connecting an extension member to the grip end, only the length of the shaft is changed, and other elements cannot be changed. There is.

  The object of the present invention has been devised by paying attention to such inconveniences, and the object is to make it possible to replace the grip member without replacing the shaft, and to change the characteristics such as length and rigidity. It is to provide a golf club capable of doing this.

In order to achieve the above object, the present invention adopts the structure described in the claims, and specifically, a shaft fixed to the golf club head, a pipe for receiving the butt side of the shaft, and A grip member including a grip mounted on the outer peripheral side of the pipe,
The grip member includes a plurality of grip members having different characteristics, and these grip members are provided so as to be selectively attachable to the shaft.

Further, the present invention comprises a shaft fixed to the golf club head, a pipe that receives the butt side of the shaft, and a grip member that includes a grip attached to the outer peripheral side of the pipe,
A first member provided on the butt side of the shaft; an intermediate member provided on a grip end side of the pipe to restrict the insertion position of the shaft; and inserted from the grip end through the intermediate member. A second member coupled to the one member;
A plurality of grip members having different positions of the intermediate member in the pipe are provided, and the first and second members are connected by selectively using any one of the grip members according to the grip member. The configuration is such that the length can be changed.

The present invention further includes a shaft fixed to the golf club head, a pipe that receives the butt side of the shaft, and a grip member that includes a grip attached to the outer peripheral side of the pipe,
A first member provided on the butt side of the shaft; an intermediate member provided on the grip end side of the pipe; and a first member inserted from the grip end and connected to the first member via the intermediate member. Two members,
A plurality of grip members having different rigidity of the grip and / or the pipe are provided, and by selectively using any one of the grip members, the first member and the second member are connected, so that the rigidity depends on the grip member. It is configured so that it can be changed.
Here, the state in which the rigidity is different is performed by varying at least one of the length, thickness, weight, and material of the grip and / or the pipe.

  In the present invention, the first member and the intermediate member are fitted so as not to rotate relative to each other along the axial direction of the shaft, and the second member penetrates the intermediate member to the first member. It can be configured by an engageable bolt.

  Moreover, it is preferable to take the structure that the spacer located on a substantially coaxial line with the said pipe is provided so that arrangement | positioning is possible between the said intermediate member and a grip end.

  According to the present invention, since a desired grip member can be selected from a plurality of grip members having different characteristics and can be attached to the shaft, the shaft length, hardness, weight, balance, grip thickness, backline The angle, grip material, color, etc. can be easily changed to meet various user needs.

  Specifically, since a plurality of grip members having different positions of intermediate members that regulate the insertion depth of the shaft with respect to the pipe are provided, the length of the golf club can be increased by simply replacing the grip members. This makes it possible to reduce the economic burden when reshafting, and to eliminate the inconvenience of making the head side heavier.

  Moreover, when it is set as the structure which provides the several grip member from which the length of a grip and / or a pipe differs, it becomes possible to change the rigidity of a shaft, without reshafting.

  Furthermore, the first member provided on the butt side of the shaft and the intermediate member provided on the grip end side of the pipe are fitted so as not to be relatively rotatable, and the second member is the first member via the intermediate member. Therefore, even if the grip member and the shaft are relatively movable in the axial direction, there is no inconvenience that the grip rotates around the shaft.

  In addition, in the configuration in which the spacer is disposed between the intermediate member and the grip end, the shape stability on the grip end side can be secured, and the grip is recessed even when a space is generated between the intermediate member and the grip end. The possibility of being bent or bent can be effectively avoided.

The first member 15 includes a cylindrical body 16 to be inserted into the shaft 12, an end wall 17 positioned on the upper end side in the figure of the cylindrical body 16 and seated on the butt end of the shaft 12, and the end wall 17 And a prism portion 20 having an internal thread 18 formed on the inner peripheral side. A step portion 17A is formed on the outer peripheral side of the end wall 17, and the cylindrical portion 16 is fixed in the shaft 12 via an adhesive or a double-sided tape with the shaft 12 abutting against the step portion 17A. Has been.

  In the present embodiment, as shown in FIGS. 4A to 4C, the grip member 13 has three types (hereinafter referred to as the first grip member 13A, the first grip member 13A, and the first grip member 13) that can vary the insertion depth of the shaft 12. 2 grip member 13B and third grip member 13C). The first grip member 13A has the deepest insertion depth of the shaft 12, the second grip member 13B has an insertion depth 0.5 inches shorter than the first grip member 13A, and the third grip member 13C The insertion depth is further reduced by 0.5 inch. Therefore, in this embodiment, when the golf club in which the first grip member 13A is mounted on the shaft 12 is replaced with the third grip member 13C, the golf club can be changed to a golf club that is one inch longer.

  As shown in FIG. 3, the grip member 13 includes a pipe 22 that receives the butt side of the shaft 12 and a grip 23 that is attached to the outer peripheral side of the pipe 22. The pipe 22 can be made of, for example, a material such as carbon or stainless steel, and the inner diameter of the pipe 22 can be relatively moved (inserted / removed) in the axial direction with respect to the shaft 12 with the shaft 12 received without looseness. Is provided. An intermediate member 25 for restricting the insertion position of the shaft 12 is fixed to the inner periphery of the upper part in the figure which is the grip end side of the pipe 22. The intermediate member 25 has an inner surface shape corresponding to the outer surface shape of the prismatic portion 20 of the first member 15, and a receiving portion 26 that can receive the prismatic portion 20, and communicates with the receiving portion 26 to be on the grip end side. And a through hole 28 through which a bolt 27 as a second member can pass.

  The intermediate member 25 is fixed to the inner peripheral side of the pipe 22 using an adhesive or a double-sided tape. The upper end of the outer periphery of the intermediate member 25 in FIG. 3 is formed with a step portion 25A that can be seated on the end of the pipe 22, and the intermediate member 25 with respect to the pipe 22 by abutting the step 25A against the end of the pipe 22. The fixed position is determined.

  The pipe 22 and the grip 23 are substantially the same length as the pipe 22 is slightly shorter than the grip 23. The grip 23 is fixed to the outer periphery of the pipe 22 via an adhesive, a double-sided tape or the like, and the grip 23 and the pipe 22 are integrated in a state in which relative rotation is impossible. Note that a hole 23B is formed in the grip end 23A of the grip 23, and a bolt 27 can be inserted through the hole 23B. It can be screwed.

  As shown in FIG. 4, among the plurality of grip members 13A to 13C, the grip 23 constituting the second and third grip members 13B and 13C is formed from a tubular body between the intermediate member 25 and the grip end 23A. The spacer 30 is disposed so as to be substantially coaxial with the pipe 22, and the presence of the spacer 30 allows the shape of the grip 23 between the grip end 23 </ b> A and the intermediate member 25 to be stably maintained. ing.

In the above configuration, for example, as shown in FIG. 4A, when the first grip member 13A is attached to the shaft 12, the golf club is the shortest in this embodiment. Here, when it is desired to increase the club length by 0.5 inches, the engagement by the bolt 27 as the second member fastened to the female screw 18 of the first member 15 is released, and the shaft 12 is moved to the grip member. What is necessary is just to extract from 13A.
Then, the extracted shaft 12 is inserted into the second grip member 13B, a bolt 27 is inserted into the hole 23B of the grip end 23A, and is fastened and fixed to the female screw 18 via the intermediate member 25. You can complete the exchange.
Also, when the third grip member 13C is used, it can be replaced by performing the same operation, and a golf club that is 1 inch longer than that using the first grip member 13A can be obtained.

  Therefore, according to the present embodiment, by selecting any one of the grip members 13A to 13C and attaching the grip member to the shaft 12, for example, a longer shaft can be given a characteristic of extending a flight distance, or a shorter shaft can be used as a direction. It is possible to change characteristics such as pursuing the stability of

Next, other embodiments of the present invention will be described with reference to FIG.
This embodiment is characterized in that three types of grip members 13A, 13D, and 13E having different lengths of the pipe 22 and / or the grip 23 constituting the grip member 13 are prepared.
Specifically, the first grip member 13A shown in FIG. 5 (A) is substantially the same as that shown in FIG. 4 (A), and is based on the first grip member 13A. Further, in the fourth grip member 13D of FIG. 5B, the pipe 22 and the grip 23 are set to be shorter by 1 inch, respectively, and the fifth grip member 13E of FIG. 5C is connected to the first grip member 13A. On the other hand, the pipe 22 is set to be 2 inches longer.
Therefore, it is possible to change the rigidity of the shaft 12 by selecting any one of the grip members 13A, 13D, and 13E and attaching it to the shaft 12.
For example, in a state where the first grip member 13A is replaced with the fourth grip member 13D, the grip member 13D is shortened, and as a result, the rigidity of the entire shaft is lowered, so that the golf club can be easily bent. . Further, when the first grip member 13A is replaced with the fifth grip member 13E, the rigidity of the entire shaft is increased by the amount of the pipe 22 set to be long. Become.
Therefore, for example, the user can select the grip member 13 that seems to be appropriate in relation to his / her head speed, and can replace the grip member 13 with the optimum one according to the progress of the level.
