Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a grip for a golf club, and more particularly to a grip for a golf club using a tube made of a rubber-like material.

[Prior art and its problems]

Generally, grips for golf clubs include a so-called leather grip formed by wrapping a leather tape around the shaft.
It is broadly divided into so-called rubber grips, which are integrally molded into a cylindrical shape from rubber material and are attached to the club shaft. Since the leather grip knob is made of leather, it can be held firmly and has excellent adhesion between the hand and the grip, but the disadvantage is that the surface deteriorates and becomes slippery after long-term use. There is. On the other hand, since rubber grips are made of rubber, the surface will not deteriorate even after long-term use.
Although it is difficult for the hand to slip, since it is a cylindrical molded body, it is difficult to adjust the thickness of the grip, and it is also difficult to replace the grip.

[Means for solving problems]

In view of the above drawbacks, the present invention provides a grip for a golf club formed by spirally wrapping a tube made of a rubber-like material around the outer periphery of the proximal end of a club shaft.

[For production]

Since the grip according to the present invention uses a tube made of a rubber-like material, the surface does not easily deteriorate even after long-term use. Therefore, your hands will not become slippery even after long-term use. In addition, a tube made of a rubber material is attached to the clubsha 71.
- The thickness of the tube can be easily adjusted by adjusting the tension when wrapping around the outer periphery, so the thickness of the grip can be easily adjusted. Moreover,
Since a buffer chamber such as an air chamber can be formed inside the tube, the grip can be firmly grasped, and the shock at the time of impact can be buffered by the buffer chamber inside the tube.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 to 3 show one embodiment of the present invention. Referring to these figures, a tube 12 made of a rubber-like material is wound helically around the outer peripheral surface of the proximal end of the club shaft 11. Both ends of the tube 12 are beveled and fixed onto the club shaft 11 by respective fixing bodies 13, 14. The fixed body 13 at the base end of the club shaft 11 has a camp shape and closes the opening at the base end of the club shaft 11. The other fixed body 14
has a ring shape and is attached to the outer periphery of the club shaft 11.

Tube 12 can be made of natural rubber, synthetic rubber, or the like. A large number of grooves or protrusions can be formed on the surface of the tube 12 to prevent slipping.

In this embodiment, the tube 12 has the same outer diameter and inner diameter in the longitudinal direction, so the wall thickness is constant, but since the tube 12 is made of a rubber-like material and has elasticity, By adjusting the tension when winding the tube around the club shaft 11, the thickness of the tube 12 can be adjusted. Therefore, the thickness of the grip can be arbitrarily adjusted by adjusting the tension of the tube 12.

Although the tube 12 before wrapping has a circular ring-shaped cross section, it may have an oval ring-shaped cross section. In any case, when the tube 12 is wound around the outer peripheral surface of the club shaft 11, the tube 12 assumes a substantially flattened ring shape, as shown in FIG. At this time, the cavity within the tube 12 is also collapsed, but an air layer can remain within the tube 12. This air layer extends spirally along the winding direction of the tube 12. Since such an air layer is formed within the grip, it is possible to firmly grasp the grip. Further, since the impact transmitted from the club head to the club shaft at the time of impact is buffered by this air layer, the impact transmitted to the player's hands is alleviated.

The tube 12 can be easily replaced as in the case of a leather grip. Further, since the tension of the tube 12 can be changed by rewinding the tube 12, the thickness of the grip can be easily changed.

FIG. 4 shows another embodiment of the invention.

In the figure, the same reference numerals are attached to the same constituent elements as in the above embodiment. In this embodiment, a tape 15 made of cork material is interposed between the club shaft 11 and the tube 12 made of a rubber-like material. The tape 15 is spirally wound around the outer peripheral surface of the club shaft 11, and the tube 12 is spirally wound around the outside of the tape 15.

The tape 15 may have a constant thickness in the longitudinal direction, but in this embodiment, the thickness of the tape 15 gradually changes in the longitudinal direction, and the thickness in the width direction of the tape 15 changes gradually. The thickness is also gradually changing.

The dimensions of this child loop 15 are set so that when it is spirally wound around the outer circumferential surface of the club shaft 11 having the same outer diameter in the longitudinal direction, the outer circumferential surface becomes a smooth tapered surface. The other configurations are the same as those of the above embodiment.

FIGS. 5 and 6 each show a modification of the tube 12 made of a rubber-like material. Tube 1 shown in Figure 5
2 has a constant outer diameter in the longitudinal direction and an inner diameter that gradually changes in the longitudinal direction. On the other hand, the tube 12 shown in FIG. 6 has an inner diameter that is constant in the longitudinal direction and an outer diameter that gradually changes in the longitudinal direction. The thickness of the tube 12 shown in FIGS. 5 and 6 gradually changes in the longitudinal direction, so when it is wound spirally around the outer circumferential surface of the club shaft, the club shaft remains constant in the longitudinal direction. Even when the grip has an outer diameter, the grip surface can be formed into a tapered shape.

Although the illustrated embodiments have been described above, the present invention is not limited to only the aspects of the illustrated embodiments.

For example, the outer diameter and inner diameter of a tube made of a rubber-like material may vary gradually in the longitudinal direction. Further, various methods used for leather grips can be used to fix the tube end. Furthermore, the inside of the tube can be filled with an appropriate amount of viscous fluid, such as silicone, and by configuring it in this way, the cushioning effect of the grip can be further enhanced.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, since a tube made of a rubber-like material is used for the grip, the grip surface is less likely to deteriorate even after long-term use. Therefore, your hands will not become slippery even after long-term use.

Furthermore, the thickness of the tube can be easily adjusted by adjusting the tension when wrapping the tube made of a rubber-like material around the outer periphery of the club shaft, so the thickness of the grip can be easily adjusted. Furthermore, since a buffer chamber such as an air chamber can be formed within the tube, it is possible to firmly grasp the grip, and it is also possible to provide a grip for a golf club that can buffer the impact at the time of impact due to the buffer chamber within the tube. .
