Description

  The present invention relates to a golf club grip and a golf club. More specifically, the present invention relates to a golf club grip whose length can be shortened and a balance between the club designed at the time of manufacture by shortening the length of the grip. The present invention relates to a golf club that can be changed.

A golf club shaft is configured to have a grip on the rear end side of the shaft, and in many cases, has a tapered outer shape with a tapered tip, and a general weight is about 50 grams.
Since such a grip itself has a weight, it is an element that determines the balance of the entire golf club, and the ease of use and control differ depending on whether the balance is good or bad. Become.

  Patent Document 1 proposes a golf club grip that improves the weight balance of the entire club and pursues ease of use.

JP 11-319172 A

  However, the thing of patent document 1 provides the grip specialized for the putter, and the balance with respect to the central axis of a shaft was adjusted by setting it as the weight distribution which an inner side becomes heavy rather than the head side with respect to a central axis. It is not intended to adjust the weight balance in the length direction of the shaft. That is, the grip described in Patent Document 1 maintains a certain length and cannot be shortened.

  By the way, when the head speed is constant, the golf club can fly the ball farther if the head weight is heavy. For this reason, some golfers who have purchased commercially available golf clubs increase the head weight by attaching a heavy object such as a lead plate to the head.

However, when the head weight is increased, the head speed tends to decrease correspondingly, and as a result, it is offset and the expected flight distance cannot always be extended.
In addition, when a heavy object is attached to the head, the center of gravity position of the designed head is also changed, and the risk that the golfer alters the easily controlled center of gravity position set as the optimum position by the manufacturer. There is also.

  Therefore, if the weight feeling on the head side can be changed by adjusting the balance of the golf club without performing any special work on the head side, it is possible to meet the demands of many golfers.

[Object of invention]
An object of the present invention is to adjust the balance of a golf club by focusing on a grip constituting the golf club so that the length of the grip can be shortened easily and quickly. It is to provide a grip that can be expected to increase the flight distance by changing the distance and a golf club using the grip.

In order to achieve the above object, the present invention employs the structure described in the claims, and specifically , the head is attached to the other end of the shaft having the head attached to one end, and the head is the head. In the golf club grip facing the side ,
On the outer periphery on the tip side of the grip, a plurality of cutting allowance portions are provided at predetermined intervals in the extending direction of the grip, and a plurality of grip portions that can be separated from each other are formed.
The plurality of grip portions include a grip portion positioned between a cutting allowance portion on the most distal end side of the grip and a tip end of the grip, and a grip portion positioned between two adjacent cutting allowance portions, In particular, the grip portion positioned forward is longer than the grip portion positioned rearward .

  In this invention, it is preferable that the said cutting | disconnection allowance part is comprised by a slit groove | channel or a perforation.

  Furthermore, a configuration is adopted in which the tip side is set to have a heavy weight distribution by adding metal powder to the rubber composition as the molding material of the grip.

  Further, according to the present invention, a golf club in which a head is attached to the front end side of the shaft and a grip is attached to the rear end side is provided with any of the above-described golf club grips.

According to the grip of the present invention, the grip can be partially cut by the cutting allowance portion, whereby the overall length of the grip can be shortened. A golf club using a grip having a shorter overall length as described above makes the head feel heavier even though the weight of the head is the same as a result of reducing the weight of the grip. , And some golfers can extend their flight distance.
The golf club uses a technique that captures the weight on the head side with a 14-inch position from the grip end as a fulcrum. Lightening is evaluated as “up 1 point” or “down 1 point”, and the state where the point rises in this way is regarded as “the head works”. On the other hand, if the grip becomes heavier or lighter by about 6 grams, it will be "down 1 point" or "up 1 point".

By configuring the cutting allowance portion with a slit or a perforation, the cutting position can be easily visually confirmed, and cutting can be performed at an accurate position.
Moreover, since the cutting | disconnection permission part is provided in the front-end | tip side of a grip, since the area | region which is not involved as an area | region gripped in actual use will be cut off, there will be no trouble in gripping the grip.

  In addition, the metal weight is added to the rubber composition, which is a material forming the grip, to distribute the weight on the tip side, so that the weight per unit length on the tip side can be maintained with the grip wall thickness kept constant. Can be made relatively heavy, and the position where the cutting permission portion is provided can be set within a short range. That is, the expected weight reduction can be achieved by separating the short length.

1 is a schematic front view of a golf club according to an embodiment. The expanded sectional view of a grip. The principal part enlarged view of FIG.

  Hereinafter, an embodiment in which the present invention is applied to an iron golf club will be described with reference to the drawings.

In Figure 1, a golf club 10, while the head 12 is attached to one end of the shaft 11 (distal end side), a grip 13 is attached to the other end of the shaft 11 (rear end side). The grip 13 is formed by using a rubber composition containing natural rubber and synthetic rubber as a molding material, and compounding the molding material with a metal powder having a high specific gravity, in this embodiment, tungsten. When forming the grip, the tungsten powder has a large blending amount per unit length so that the tip side of the grip 13 is heavily distributed.

  In the grip 13, slit grooves 15, 16, and 17 are formed along the outer periphery on the distal end side as cutting permission portions. As shown in FIGS. 2 and 3, the slit grooves 15 to 17 are formed at positions with intervals L 1, L 2, and L 3 along the extending direction of the grip 13, and are cut by the slit grooves 15 to 17. Thus, grip portions 13A, 13B, and 13C that can be separated are formed. Here, the distance L1 from the tip of the grip 13 to the slit groove 15 is 20 mm, the distance L2 from the slit grooves 15 to 16 is 15 mm, and the distance L3 from the slit grooves 16 to 17 is 10 mm. The grip 13 in this embodiment has a weight of 50 grams and a total length of about 270 mm. Therefore, even if the grip portion 13C is cut off, an area that can be gripped with both the left and right hands remains 225 mm. Because there is no trouble. The weights of the grip portions 13A, 13B, and 13C are set to about 6 grams, 5.5 grams, and 5 grams, respectively.

  The golf club 10 can be used after being cut by one of the slit grooves 15 to 17 as necessary after the golfer purchases it. This cutting can be performed by applying a cutter knife to the groove and cutting the grip 13 in the circumferential direction. Incidentally, when the grip portion 13A is cut by cutting with the grip 15, the weight of 6 grams is reduced. Therefore, as described above, the balance of the golf club 10 as a whole can be increased by about 1 point on the head side, and by making the head feel heavier, the golfer can extend the flight distance.

  Therefore, according to such an embodiment, the grip 13 can be lightened by separating the grip portions 13A to 13C, and a golf club balance point on the head side is relatively increased to expect a flight distance increase. It is possible to provide a golf club grip that can be used.

The best configuration, method and the like for carrying out the present invention have been disclosed in the above description, but the present invention is not limited to this.
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 case where the cutting permission portion is configured by the slit grooves 15 to 17 is illustrated and described, but a perforation may be formed. In short, the present invention only needs to specify a position at which the grip can be cut and be provided so that the cutting can be easily performed .
Further, the golf club to be applied is not limited to the iron golf club, so-called, wood-type golf club, utility golf club, can also be applied to the putter.
