Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a grip for a golf club, and more specifically, a grip for a golf club in which a number of grooves extending in the circumferential direction of the grip body are formed on the surface of the grip body. Regarding the improvement of

[Conventional technology]

In general, centrifugal force acts on a golf club during a golf swing, so the grip of the golf club tends to slip from the player's hand in the longitudinal direction, causing the golf club to slip out of the player's hand or the position of the club head to strike the ball to be misaligned. This may cause

As a means to prevent the grip from coming off or slipping due to the centrifugal force of the swing, as shown in FIG.
A method has been considered in which the grip body 1 is formed at intervals in the longitudinal direction of the grip body 1.

[Problem that the invention attempts to solve]

However, in the groove shape of the conventional grip described above, the groove side wall surface 2a facing the head side is formed at right angles to the bottom surface of the groove 2 and the outer surface of the grip body 1. When a compressive force is applied in the radial direction to the ridges 3 between the adjacent grooves 2 of the grip body 1 by grasping the handle, the groove side wall surface 2a facing the head side expands outward due to the compressive deformation of the ridges 3. The angle between the side wall surface 2a and the outer surface of the grip main body 1 becomes an even larger angle than a right angle. Furthermore, when centrifugal force acts on the protrusion 3 during swinging, the protrusion 3 deforms toward the rear end of the club shaft, so that the groove side wall surface 2a facing the head side and the outer surface of the grip body 1 The angle becomes an even larger angle than a right angle.

Because of the above-mentioned deformation, in conventional golf club grips, grooves extending in the circumferential direction of the grip main body 1 serve to prevent the grip from slipping off from the player's hand against the action of centrifugal force generated during a swing. A problem has arisen in that the anti-slip function in the longitudinal direction is not sufficiently achieved.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a grip for a golf club that can reliably prevent the grip of the golf club from slipping out of the player's hand or slipping in the longitudinal direction of the grip during the swing.

[Means for solving problems]

As a means to solve the above-mentioned problems, the present invention provides a grip that is attached to the outer surface of a cylindrical grip body having rubber-like elasticity that is attached to the outer peripheral surface of the rear end side of a club shaft to which a head is attached at the tip. A grip for a golf club in which a plurality of grooves extending in the circumferential direction of the main body are provided at intervals from each other in the longitudinal direction of the grip main body, the groove side wall surface facing the head side of the groove extending in the circumferential direction and the outer surface of the grip main body. To provide a grip for a golf club, characterized in that the angle formed between the grip and the grip is smaller than a right angle.

[Effect]

In the grip for a golf club according to the present invention, since the angle between the groove side wall surface facing the head side of the groove extending in the circumferential direction and the outer surface of the grip body is smaller than a right angle, the longitudinal direction of the grip body The ridge between the two adjacent grooves tends to get wedged into the grip surface of the player's hand like a wedge against the centrifugal force acting on the golf club during the swing. Therefore, it is possible to reliably prevent the golf club from slipping or coming out of the grip of the golf club or the player's hand in the longitudinal direction during the swing.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

1 to 5 show embodiments of the present invention. Referring to these figures, a grip 11 for a golf club includes a grip body 12 having a substantially bottomed cylindrical shape, and the grip body 12 is attached to the rear end side of a club shaft 13 having a head 14 attached to the tip. It is fixed with adhesive or the like.

Here, a large number of annular grooves 15 extending in an annular shape in the circumferential direction are formed on the outer surface of the grip body 12 at approximately equal intervals in the longitudinal direction of the grip body 12. In FIGS. 4 and 5, arrow A indicates the direction in which centrifugal force acts when the golf club is swung. Referring to FIGS. 4 and 5, the groove 15 has a forward side wall surface 15a facing the tip side of the club shaft 13, that is, the head 14 side, a rearward side wall surface 15b opposite to the side wall surface 15a, both side wall surfaces 15a, 15b. Here, the bottom surface 15c of the groove 15 extends substantially parallel to the outer surface of the grip body 1, and the rearward side wall surface 15b of the annular groove 15 is parallel to the forward side wall surface 15a of the annular groove 15. ing. As can be seen from these figures, the annular groove 1
The forward side wall surface 15a of No. 5 is the bottom surface 1 of the annular groove 15.
5c and the outer surface of the grip body 12 to form an angle θ smaller than a right angle. This front side wall surface 15a and the grip body 12
The angle it makes with the outer surface (here approximately equal to angle θ) becomes even more acute due to the compression effect when the player grips the grip.

The grip for a golf club having the above structure can be easily manufactured by vulcanization molding using a grip mold using synthetic rubber such as butadiene rubber, ethylene-butadiene rubber, isoprene rubber, or natural rubber as a raw material.

According to the golf club grip having the above configuration,
As shown in FIG. 5, when the golf club is swung, the grip body 12 is moved by centrifugal force.
tries to escape from the player's hand in the direction of arrow A. Therefore, the annular groove 15 is deformed in the direction of arrow B, as shown by the dotted line in FIG. However, when the player grips the grip body 12, a radial grip force P acts on the protrusion 16 between the two longitudinally adjacent annular grooves 15 of the grip body 12. Since the protruding portion 16 deforms in the direction of arrow C, the deformation in the direction of arrow B and the deformation in the direction of arrow C cancel each other out. Therefore, the amount of deformation δ2 in this groove-shaped grip is smaller than the amount of deformation in the conventional groove-shaped grip. In this way, the amount of deformation δ2 of the grip is small, and the angle between the forward side wall surface 15a of the annular groove 15 and the bottom surface is maintained at an angle smaller than a right angle, so that the annular shape with respect to the surface of the player's hand and fingers is maintained. The forward side wall surface 15a of the groove 15 bites in like a wedge. Therefore, the golf club can be prevented from slipping, slipping, or slipping out of the player's hand in the longitudinal direction.

6 and 7 show an example in which the present invention is further provided with longitudinal anti-slip grooves. In the figures, the same reference numerals are given to the same components as in the above embodiment.

Here, the grip body 12 is provided with a plurality of longitudinal grooves 17 extending in the longitudinal direction of the grip body 12, in addition to an annular groove 15 having the same structure as the annular groove 15 of the above embodiment. The longitudinal groove 17 has opposite side wall surfaces 17a, 17b and both side wall surfaces 17a,
17b and a bottom surface 17c.

During the swing, a rotational moment due to the weight of the club head acts on the club shaft 13 and the grip body 12, so that the grip body 12 tends to rotate in the direction of arrow D in FIG. 7 with respect to the player's hand. Therefore, the grip body 12 is deformed in the direction of arrow E in FIG. Therefore, in this example, the angle between the side wall surface 17a of the longitudinal groove 17 facing the direction of the rotational moment acting on the club shaft 13 during the swing and the bottom surface 17c of the longitudinal groove 17 is smaller than a right angle. It is formed so that.

Therefore, in this example, the same effect as in the above embodiment can be obtained against the centrifugal force action during the golf swing, and the longitudinal groove 17 and the player's hand and This improves the grip of the finger surface, making it less likely that the grip will slip or shift in the circumferential direction.

Although the illustrated embodiments have been described above, the present invention is not limited to only the aspects of the above-mentioned embodiments, and various changes can be made to its constituent elements within the scope of the invention described in the claims for utility model registration. be able to. For example, the number, spacing, etc. of the grooves extending in the circumferential direction of the grip body can be variously selected.

[Effect of idea]

As is clear from the above explanation, according to the present invention, the angle between the groove side wall surface facing the head side of the groove provided in the circumferential direction of the grip surface and the outer surface of the grip body is smaller than a right angle. Because
The protrusion between the two grooves adjacent to each other in the longitudinal direction of the grip body tends to get wedged into the grip surface of the player's hand like a wedge against the centrifugal force acting on the golf club during the swing. Therefore, it is possible to provide a golf club grip that can reliably prevent the golf club from slipping or slipping out of the player's hand in the longitudinal direction during swinging.
