Description

  The present invention relates to a golf club grip.

  A general golf club grip is formed of a rubber material in a bottomed cylindrical shape, and is inserted into an end portion of a club shaft and bonded to the shaft integrally with an adhesive.

  The grip is provided with a line-like protrusion, which is proved as a back line, at a position below the grip for reference of the club direction and address. These streak protrusions are formed so that the predetermined part of the inner peripheral surface of the grip is thick and flat, or a protrusion is formed in advance on the outer peripheral surface or the inner peripheral surface so that the protrusion appears when the shaft is mounted. (Patent Document 1 FIG. 10, Patent Document 2).

  In particular, there is disclosed a means for forming a back line (rib) by forming a concave line at a boundary portion with a grip as an inner / outer double structure, and by installing a protruding body in the concave line (Patent Document 1).

  Further, although not the means for forming the back line, Patent Document 3 discloses means for embedding a metal fine wire having a diameter of about 100 microns in the thickness of the grip as means for adjusting the grip weight corresponding to the head weight. Is disclosed.

JP 2000-176061 A. JP2003-180892A. Japanese Utility Model Laid-Open No. 5-28363.

  When forming the back line of the grip, the means for providing the protrusion on the inner peripheral surface, particularly when a part of the inner peripheral surface is formed flat (FIG. 10 of Patent Document 1), is easy to insert the shaft. In addition, there is a problem that the back line is difficult to appear clearly, and even when protruding from the outer periphery, the grip is made of a rubber material and extends when the shaft is mounted, and at the same time, an anti-slip uneven strip is formed on the grip surface. Therefore, it is difficult to form so that the protruding line of the back line appears clearly.

  As a means for solving the above-mentioned problem, Patent Document 2 states that when a protrusion is formed on the inner peripheral surface of the grip, the back line appears clearly when the grip is attached to the shaft. In addition, the shaft mounting work is complicated, and the protrusion is formed at an acute angle, so that stress that is biased in the axial direction of the back surface of the shaft acts, which may cause an unstable element when hitting the ball.

  Of course, when the double structure described in Patent Document 1 is adopted, there are complicated manufacturing and cost problems.

  Further, as described in Patent Document 3 in adjusting the weight and rigidity of the grip, in order to embed a large number of metal fine wires in the grip, it is necessary to incorporate them when forming the grip, and the manufacturing is troublesome. Also, fine adjustment after manufacturing the grip is difficult.

  Therefore, the present invention proposes a new grip for a golf club that has a simple structure, can reveal a clear back line, and can adjust grip rigidity.

A grip for a golf club according to the present invention has a cylindrical shape that encloses a hole into which a shaft of a golf club is inserted, and a part of an inner peripheral surface is formed thin and thick in a direction parallel to the shaft to be mounted. A thick strip portion is provided, and a metal steel wire of φ0.7 to 1.1 mm is embedded in the thick strip portion except for a range of 5 to 10 mm of the grip tip portion and the end portion. It is.

  Thus, when the grip is attached to the shaft, the thick strip portion bulges out to form a back line. Particularly, since the thick steel strip has a metal steel wire, the metal steel wire passes through the grip material. It will come out and a clear backline will appear.

  Furthermore, since the metal steel wire is inherently parallel to the shaft in the grip, the rigidity of the grip portion in the shaft changes, and by setting the thickness and length of the metal steel wire in advance, a desired value can be obtained. A golf club having a hit feeling can be obtained.

  Further, in the present invention, a metal steel wire insertion hole opened at the grip opening side end of the thick strip portion is formed, and the metal steel wire is inserted and embedded in the insertion hole, or on the inner peripheral surface of the strip formation portion. When a concave groove for embedding a metal steel wire is formed, and the metal steel wire is embedded in the concave groove, the metal steel wire is not incorporated at the same time as forming when the grip is manufactured, and when the grip is attached to the shaft. In addition, the thickness, length, and presence / absence of division of the metal steel wire can be selected.

  Since the present invention is as described above, by including a metal steel wire in the formation of the back line, the back line appears clearly and the club performance (shaft performance) can be easily selected and adjusted. It is a thing.

  Next, an embodiment of the present invention will be described. The golf club grip shown in the embodiment includes a grip body 1 and a metal steel wire 2.

  The grip body 1 is basically the same as before, and is made of a rubber material (generally, artificial rubber). The grip body 1 has a cylindrical shape that encloses a hole 11 into which a shaft A of a golf club is inserted. Of the metal steel wire 2 opened at the grip opening side end of the thick strip portion 12. An insertion hole 13 is formed.

  The metal steel wire 2 is a φ1 mm piano wire having a length of 200 mm and is inserted into the insertion hole 13 so that the insertion tip is 7 mm from the grip end.

  When the grip body 1 in which the metal steel wire 2 is embedded is attached to the shaft A by a usual method, the back surface 14 appears clearly on the surface of the gup by being pushed out by the metal steel wire 2. become.

  Moreover, when a ball is hit with a golf club equipped with the above-mentioned grip, the shaft vibration (sound wave acquired by the microphone attached to the shaft) is as shown in FIG. 3 (a), and the metal steel wire 2 is not embedded. The hit with a golf club fitted with the grip was as shown in FIG.

  In terms of feel at impact, the club in which the metal steel wire 2 was embedded was easier to swing and the catch of the ball was better.

  Then, when various hitting checks were performed by varying the head speed, the length, position, and diameter of the metal steel wire 2, the length of the metal steel wire 2 was in the range of 207 to 210 mm, and the tip position from the grip end was 5 The feeling of impact was good when the diameter of the metal steel wire (when a piano wire was used) was 0.7 to 1.1 mm at a position 10 mm away.

  Moreover, the embedding means of the metal steel wire 2 and the location where the thick strip portion 12 is formed according to the present invention are not limited to the above embodiment, but instead of the insertion hole 13 as shown in FIG. The recessed groove 15 for embedding may be formed, and the metal steel wire 2 may be embedded in the recessed groove 15.

  In particular, when a structure in which the metal steel wire 2 is embedded in the concave groove 15 is adopted, the metal steel wire 2 is divided in the length direction instead of one, a thin steel wire is bundled or twisted steel wire Can also be adopted.

The principal part longitudinal cross-sectional view of embodiment of this invention. In the cross-sectional view, (a) shows the state before the shaft is mounted (b) after the shaft is mounted. In the shaft vibration graph in the same use state (at the time of hitting the ball), (a) shows a product according to the present invention (b) shows a conventional product. Explanatory drawing (cross-sectional view) of another example of the metal steel wire embedding means. It is a cross-sectional view of another example of the formation position of the thick strip portion, (A) before the shaft mounting (B) after the shaft mounting.
