Fig. 4, Fig. 4 is a left side view of Fig. 3, and Fig. 5 is VV of Fig. 3.
5 is a sectional view taken along the line, and FIG. 6 is a sectional view showing a modification of this embodiment.
FIG. 7 is an explanatory diagram showing a usage state of the golf club shown in FIG. 1.

As shown in FIGS. 1 and 3, in the grip 3 attached to the shaft 2 of the golf club 1 as a hitting tool, a fitting hole 5 formed in the central portion of the grip body 4 in the central axis C direction. The shaft 2 is fitted to the inner peripheral surface 6 of the fitting hole 5 and the outer peripheral surface 7 of the shaft 2 are fixed to each other. The outer surface 8 of the grip body 4 is provided with irregularities 9 that match the predetermined handprint 20 (FIG. 7) of the user in the correct grip state. There are several kinds of correct gripping states, but in this embodiment, one of the correct gripping methods will be described as an example.

A lid portion 10 is integrally formed at one end of the grip body 4 in the direction of the central axis C, and a through hole 11 for communicating the fitting hole 5 with the outside is formed in the lid portion 10. There is.
The fitting hole 5 may be penetrated without providing the lid 10.

At least the lower half (lower half in FIG. 3) of the outer surface 8 of the grip body 4 is from the index finger of one hand of the user (for example, the right hand in the case of a right-handed person) to the ring finger and the other. The first uneven portion 12 corresponding to a correct grip state from the index finger to the little finger of the hand (for example, the left hand) is formed in a wavy shape. At least an upper half (upper half in FIG. 3) of the outer surface 8 of the grip body has a second uneven portion corresponding to a correct grip state of the thumb and the index finger of the one hand (right hand) and the thumb of the other hand (left hand). 13 is formed. First uneven portion 12 and second uneven portion 13
Thus, the unevenness 9 is formed. It should be noted that the wavy first uneven portion 12 formed in the lower half extends from the lower half to the upper half, and the second uneven portion 13 formed in the upper half extends from the upper half to the lower half, respectively. It is preferable to continuously form the fingers because each finger easily fits in the first and second uneven portions 12 and 13.

A grip 3 is attached to the shaft 2 of the golf club 1.
When mounting, double-sided tape with adhesive applied on both sides is wound around the shaft outer peripheral surface 7, and then the shaft 2 is gripped while the inner peripheral surface 6 of the fitting hole 5 is wet with a solvent such as gasoline. Insert into the fitting hole 5. If the solvent is evaporated in this state, the adhesive agent of the double-sided tape is fixed to the shaft outer peripheral surface 7 and the fitting hole inner peripheral surface 6, whereby the grip 3 is fixed to the shaft 2. Through hole 11 in lid 10
Since the hole is formed, when the shaft 2 is inserted into the fitting hole 5, the air and excess solvent in the fitting hole 5 will not penetrate the through hole 11.
Since it is discharged from the outside, the shaft 2 can be smoothly inserted and fixed. As shown in FIG. 5, the fitting hole 5 has a notched circular cross-sectional shape having a planar portion 14 on the upper side.

The grip 3 is integrally molded with a mold or the like, and its material is natural rubber (NR).
A rubber in which styrene-butadiene rubber (SBR) is mixed is preferable, but other materials such as synthetic resin and metal may be used. As described above, the grip 3 can be integrally molded with a mold, and thus the manufacturing is easy.

As shown in FIGS. 1 to 4, the first concave-convex portion 12 has concave portions F ₁ , F ₂ and F _{3 into} which the index finger, the middle finger and the ring finger of the right hand respectively engage, and the index finger, the middle finger and the left hand of the left hand. recess F ₁₁ to the ring finger, little finger respectively engaged, F _12, F _13, F
₁₄ and. The second concave-convex portion 13 has concave portions F ₂₁ and F ₂₂ which are respectively engaged by the thumb and the index finger of the right hand, and an engaged portion F ₂₃ which is engaged by the thumb of the left hand. Recess F ₂₂
The concave portion F ₁ has a continuous concave shape because the index finger of the right hand is engaged. The concave portions F ₂₁ and F ₂₂ are formed on both side surfaces of the mountain-shaped thick portion 15 that bulges outward, and the thick portion 15 of the second uneven portion 13 is formed by the thumb and index finger of the right hand. It is designed to be held between them. Engaged portion F ₂₃ also, the wall thickness by bulging outward has a thick Dayu structure.

As shown in FIGS. 1 to 3 and 7, when gripping the grip 3 of the golf club 1, the index finger or little finger of the left hand is engaged with the recesses F _{11 to} F ₁₄ and the thumb is engaged. Engage with the joint F ₂₃ . Then, the index finger of the right hand is engaged with the recesses F ₂₂ , F ₁ , the middle finger and the ring finger are engaged with the recesses F ₂ , F ₃ , respectively, and the thumb is depressed with the recess F _21.
To be engaged. By gripping the grip 3 with both hands in this way, the relative positions of the right hand and the left hand and the positions of the fingers of both hands are correct, and it is inevitable that the grip 3 is gripped in the correct grip state and the ball can be hit as it is. In particular, a thick and strong thick portion 15 is formed in the grip portion of the right thumb and forefinger, and the engaged portion F ₂₃ with which the left thumb is engaged has a strong structure. Thick part 1
5 and the engaged portion F ₂₃ can hold firmly pressed by the finger. Therefore, it becomes easy to swing the golf club and hit the ball. As a result, a sense of stability when hitting the ball can be obtained, and the ball can be hit accurately in a desired direction.

As shown in FIG. 5, since the fitting hole 5 has a notched circular shape, the grip body 4 is thicker on the upper half side. A particularly strong finger force is applied to the second concave-convex portion 13 on the upper half side, but since the thickness of this portion is thick, it is difficult to deform and it can be firmly held firmly. When the grip 3 is molded from rubber and the shaft 2 having a slightly larger circular cross section is inserted into the fitting hole 5, the fitting hole 5 expands and is deformed into a circular cross section. Therefore, the inner peripheral surface 6 of the fitting hole 5 and the outer peripheral surface 7 of the shaft 2 are wholly in close contact with each other and firmly fixed. In addition, as shown in FIG. 6, the fitting hole 5 of the grip 3a
A may be molded into a circular cross section, and in this case, the fitting hole 5a comes into close contact with the shaft 2 without being deformed.

Even if there is a difference in body size or gender, there is not much difference in hand size. So, for example,
If you prepare one type of grip for each right-handed and one for left-handed, you can easily handle it, but there are multiple types of grips with irregularities that correspond to the correct grip state for each size of hand. It is more preferable if prepared.

As described above, according to the present invention, a beginner can easily learn how to properly grip the grip 3 of the golf club 1. Although it is difficult for a beginner to properly teach a proper gripping method, if the gripper 3 of the present invention is used, the beginner can easily learn the proper gripping method voluntarily and positively. On the other hand, if a golf fur who has already gripped the wrong way uses the golf club 1 having the grip 3 according to the present invention, the golfer can correct the golf ball naturally so that the golfer can get the correct grip state, and the golf progress is accelerated. . Even a veteran golfer cannot always maintain the correct grip state, but if the grip 3 is used, the grip 3 can always be grasped in the correct grip manner.

As described above, anyone can easily learn how to properly grasp the grip, which is the basis for improving golf. Moreover, the golf club to which the grip is attached can actually hit the ball in a correct grip state. As a result, it is possible to naturally learn the correct gripping method while hitting the ball. This golf club 1
Can be used at a golf driving range, but can also be used for playing at a golf course in other than the official competition.

Further, in the case of a club having a conventional grip with unevenness for swing practice, the ball cannot be hit, but according to the golf club 1 of the present invention,
It is possible to hit the ball as it is while gripping the grip 3 with a proper grip. Therefore, practice can be enjoyed and actively promoted. In the case of the conventional glove type orthodontic appliance, it was impossible to use it with bare hands, but the grip 3 of the present invention can be used with bare hands or with gloves on.

If the grip 3 is molded of a rubber material, it is possible to prevent a shift when the grip 3 is gripped and swung, and to obtain a better contact feeling. In particular, the rubber-based grip 3 has an excellent friction effect, and therefore, even if the grip 3 gets wet with sweat or rainwater of the hand, it exerts an anti-slip effect during a swing. Further, since the shaft 2 can be inserted into the fitting hole 5 of the grip 3, the grip of the golf club already in use can be easily replaced with the grip 3 of the present invention.

It should be noted that if the grip of the present invention is attached to a club for head-less swing practice, the ball cannot be hit, but the proper gripping method can be learned. In the above embodiment, the case of a golf club is shown as a hitting tool, but as long as it has the grip of the present invention, it may be a hitting tool such as a tennis racket, a badminton racket, a table tennis racket, or the like. The same operational effect as the embodiment is achieved. In the drawings, the same reference numerals indicate the same or corresponding parts.

[0029]

Since the present invention is constructed as described above, it is possible to hit the ball as it is while grasping the grip in a proper gripping manner.
