Golf club balance adjuster Technical field

The present invention relates to a golf club balance adjuster for adjusting the weight balance of a golf club. Background art

It is known that adjusting the weight lance of a golf club can improve the running of the golf club head (head speed, hitting power). As a method of adjusting the weight balance of a golf club, for example, US Patent Application Publication No. 2003/014848819 discloses a cylindrical member inserted into a shaft of a golf club. It is disclosed that one or both of two weights having different weights are accommodated in the tubular member. According to this method, the weight balance of the golf club can be changed without changing the length of the golf club. A rubber grip is attached to the rear end of the shaft of the golf club. This rubber grip is formed in an elongated cylindrical shape with one end closed, attached by inserting the rear end of the shaft from its open end, and fixed to the shaft with an adhesive. I have. For this reason, the above method cannot easily adjust the weight balance of the golf club.

That is, in order to adjust the weight balance of the golf club by changing the type or number of weights in the cylindrical member, the grip must be peeled from the shaft. After the adjustment, the adhesive must be reapplied to the inner surface of the grip or the outer surface of the shaft to fix the grip to the rear end of the shaft. Because of the labor involved, the above method requires that the golfer play the golf course immediately before the start of play, depending on the green condition of the golf play day (whether the green is moist and heavy or the green is dry and light). If you adjust the weight balance of one club easily, you cannot do anything. Disclosure of the invention An object of the present invention is to provide a golf club balance adjuster capable of easily adjusting the weight balance of a golf club.

The golf club balance adjuster according to the present invention is a golf club balance adjuster (2) for moving the center of gravity of the golf club (1) to adjust the weight clearance of the golf club. Includes weights (22A, 22B) that are removably attached to the grip end of the robot. Alphanumeric characters in parentheses represent corresponding components in the embodiments described below, but this is not intended to limit the present invention to the embodiments. The same applies hereinafter in this section.

According to the present invention, since the weight is externally attached to the grip end of the golf club, it is easy to attach and remove the weight. For example, even immediately before the start of golf play, the weight can be adjusted according to the state of the green of the day. You can easily adjust the weight balance of the golf club (putter club).

The golf club balance adjuster further includes a mounting member (21) fitted into a grip end side end of the golf club shaft (11), and the weight is a grip end side end of the shaft. It is preferable that the grip (12) is detachably attached to the attachment member with the end face (122) of the grip (12) attached to the attachment member interposed therebetween.

According to this configuration, if the mounting member is fitted to the shaft, the weight is attached to the mounting member fitted to the shaft without gripping the grip from the shaft, with the grip attached to the shaft. Can be attached or detached from the attachment.

The dragon has a rod-shaped male screw portion (224) having a male screw formed on a peripheral surface thereof, and the mounting member is capable of screwing the male screw portion through a hole formed in the grip. It preferably has a female screw hole (2 11).

According to this configuration, the male screw portion of the chin can be screwed into the female screw hole of the mounting member, whereby the weight can be mounted on the mounting member.

In order to attach another weight (22B) having a male screw portion that can be screwed into the female screw hole in a state of being connected in series, the weight (22A) is screwed with the male screw portion of the other weight. Preferably, it has a possible female screw hole (2 25). According to this configuration, a plurality of weights can be attached to the grip end of the golf club in a state of being connected in series. Thus, for example, the weight balance of the putter club can be adjusted by changing the number of weights attached to the putter club grip according to the state of the green on the day of play.

5. The weight according to claim 1, wherein the weight comprises a metal weight body (2 2 1), and a rubber cover (2 2 2) attached to the weight body. 6. This is a balance adjuster for golf clubs.

According to this configuration, since the weight body is covered with the rubber cover, when the golf club is stored in the golf bag with the key attached to the grip end of the golf club, the weight is stored in the golf bag.

FIG. 2 is a perspective view showing a state in which the mounting member and the cascade are individually separated.

FIG. 3 is a cross-sectional view showing the configuration of the rubber cover. Embodiment of the Invention

FIG. 1 is a view showing a use state of a golf club balance adjuster according to one embodiment of the present invention. In the golf club 1, a club head (not shown) is attached to an end of an elongated cylindrical steel or carbon shaft 11, and a rear end of the shaft 11 (an end on a grip end side). ) And a rubber grip 12 is attached to the The grip 12 is provided so as to close a cylindrical peripheral surface 121 having a cylindrical inner peripheral surface corresponding to the outer peripheral surface shape of the shaft 11, and one end of the cylindrical peripheral surface 121. Of the cylindrical peripheral surface 1 2 1 By inserting the rear end of the shaft 11 from the release end side, the rear end of the shaft 11 is covered. In addition, an adhesive is interposed between the shaft 11 and the grip 12, and the grip 12 is fixed to the rear end of the shaft 11 by covering with the adhesive. .

The balance adjuster 2 according to this embodiment is used by adjusting the weight balance of the golf club 1 by attaching it to the grip of the golf club 1. In particular, the golf club 1 is a golf club. In some cases, it can be suitably used to improve the running (head speed, hitting power) of the putter head by adjusting the weight balance of the club.

The balance adjuster 2 can be attached to and detached from the mounting member 21 via a mounting member 21 fitted into the rear end of the shaft 11 and a hole formed in an end surface portion 12 of the grip 12. 2 A attached to the weight.

For example, the mounting member 21 is inserted into the rear end of the shaft 11 in a state where a release agent is poured between the shaft 11 and the grip 12 and the shaft 11 is removed from the grip 12. It can be installed with. After the mounting member 21 is mounted on the shaft 11, the grip 12 is attached to the rear end of the shaft 11 on which the mounting member 21 is mounted.

Another weight 22B having the same configuration as the weight 22A can be detachably attached to the weight 22A. Thus, by attaching only the weight 22A to the mounting member 21 or attaching the weight 22B to the weight 22A attached to the mounting member 21 Two 22A and 22B can be attached in a row. Since the weights 22A and 22B have the same configuration, only the weight 22B is attached to the mounting member 21 or the weight 22A attached to the mounting member 21 is attached to the weight 22A. Can be further attached. Furthermore, if another weight having the same configuration as that of Zong 22 A and 22 B is prepared, the prepared weight and the weights 22 A and 22 B can be attached to the mounting member 21 in three or more stations. It can be mounted in a row.

The weights 22 A and 22 B fit onto the shaft 11 with the grip 11 attached to the rear end of the shaft 11 without removing the shaft 11 from the grip 12. It can be attached to the embedded mounting member 21 or removed from the mounting member 21. Thus, even immediately before the start of golf play, the number of weights to be attached to the grip end of the golf club (club club 1) is changed according to the green condition on the day of play, and the putter club 1 Weight and lance can be adjusted.

For example, when the green is heavy and wet after rain or after the rain, attaching the two weights 22 A and 22 B to the mounting member 21 allows the center of gravity of the club 1 to move to the grip side. When the green is dry and light, attach only one of the weights 22 A and 22 B to the mounting member 21, or do not attach the weights 22 A and 22 B Thus, the center of gravity of the club 1 can be moved to the club head side.

The closer the center of gravity of the golf club 1 is to the grip end side, the better the running of the club head, so that the golf ball can be launched vigorously. Therefore, when the green is moist and heavy, moving the center of gravity of the golf club 1 toward the grip side can prevent the golf ball from reaching the force gap (a so-called short). Can be prevented. Conversely, when the green is dry and light, the center of gravity of the golf club 1 is moved to the club head side to prevent the launched golf ball from rolling beyond the force cap (so-called over-). it can. Therefore, by using the balance adjuster 2, the success rate of the golf ball can be drastically improved, and the score of golf play can be extended.
