BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below with reference to the illustrated embodiments. FIGS. 1 and 2 show a first embodiment, FIG. 1 is a perspective view of a golf club, and FIG. 2 is an enlarged grip of the golf club. It is a cross-sectional front view.

In the golf club, a head 2 is fixed to the lower end of a shaft 1 made of fiber reinforced resin or the like, and a grip 3 is fixed to the outer periphery of the upper end with an adhesive. Grip 3
Is made of a synthetic rubber such as butadiene rubber, ethylene butadiene rubber, isoprene rubber, urethane, etc., synthetic resin or natural rubber, and is vulcanized and molded in a mold to form a tubular shape. The outer surface 3a of the grip 3 has a large number of long grooves in the axial direction.
3b is formed. As shown in FIG. 2, the long groove 3b is formed in an inverted Y-shape by a linear groove 3c on the opening side and grooves 3d, 3d separated on the inner tip side. The grooves 3d, 3d on the inner tip side than the groove 3c on the opening side of the outer surface 3a are enlarged by a distance a to the left and right, that is, in the direction closer to the inner tip side groove 3d of the other adjacent grooves 3b on both sides. . That is, the slightly inner layer side of the groove 3b is the groove 3b on the left and right.
The grooves are enlarged in both directions close to the inner tip side groove 3d. The peripheral walls of the groove 3c on the opening side of the groove 3b are formed close to each other so as to come into contact with each other after the molding.

When the outer surface 3a of the grip 3 is grasped by the hand,
Since the peripheral walls of the groove 3c on the opening side of the groove 3b are close to each other, the deformation of the portion that directly touches the hand is small. Further, the inner tip side grooves 3d, 3d on the slightly inner layer side of the groove 3b are easily deformed according to the weight of the gripped hand. When the grip 3 is raining or sweating, the water adhering to the outer surface 3a is absorbed in the groove 3b and stored in the volume of the grooves 3d, 3d on the inner tip side.

When the grip of the golf club is constructed as described above, when the outer surface 3a of the grip 3 is gripped, the groove 3b is formed.
Since the peripheral walls of the groove 3c on the opening side are closer than the grooves 3d, 3d on the inner tip side, there is little deformation of the part that directly touches the hand, the feel is good, and the inner tip side on the slightly inner layer side of the groove 3b Groove 3
Since d and 3d are easily deformed according to the weight of the hand held,
It is a grip that fits in your hand. It feels good to hold the grip 3, and if you fit it in your hand, it will be easier to operate the golf club.
You can get good grades. In addition, the grip 3 has a groove for water adhering to the outer surface 3a when it is raining or sweating.
Since it is absorbed in 3b and accommodated in the volume of the grooves 3d, 3d on the inner front end side, it is possible to appropriately prevent the return of water and thus prevent slippage due to water.

FIG. 3 shows a second embodiment, and FIG. 3 is an enlarged sectional front view of a grip of a golf club.

In the second embodiment, a large number of long grooves 3e are formed in the axial direction on the outer surface 3a of the grip 3. Long groove 3e
Are each formed by a combination of a linear groove 3f on the opening side and a wide spherical groove 3g on the inner tip side. The inner wall 3h of the spherical wide groove 3g on the inner tip side has a large area, and the inner wall 3h of the spherical wide groove 3g on the inner tip side is adjacent to the left and right sides, that is, on both sides, than the groove 3f on the outer surface 3a on the opening side. The spherical wide groove 3g of the other groove 3e is enlarged in both directions close to the inner wall 3h of the spherical wide groove 3g to widen the tip side of the groove 3e. That is, a slightly wide inner layer side of the groove 3e is a spherical wide groove 3g which is enlarged in both directions close to the left and right spherical wide grooves 3g. The peripheral walls of the groove 3f on the opening side of the groove 3e are formed closer to each other than the inner tip side in the state after molding. Other configurations are substantially the same as those of the first embodiment.

In the second embodiment, there is little deformation of the part that comes into direct contact with the hand, and a large spherical wide groove 3g is formed slightly on the inner layer side of the groove 3e.
As a result, the deformation on the inner layer side becomes slightly larger depending on the weight of the hand that is grasped. Also, the amount of water contained in the spherical wide groove 3g can be increased.

4 and 5 show a third embodiment, FIG. 4 is an enlarged sectional front view of a grip of a golf club, and FIG. 5 is an exploded sectional front view of a mold for molding the grip of the golf club.

In the third embodiment, a large number of long grooves 3j are formed in the outer surface 3a of the grip 3 in the axial direction. Long groove 3j
Is formed by a combination of a straight groove 3k whose opening faces the outer surface 3a and an inverted U-shaped groove 3m inside. Regarding the groove 3j, the inverted U-shaped groove 3m is enlarged to the left and right by a distance c from the straight groove 3k on the outer surface 3a, that is, in the direction close to other adjacent inverted U-shaped grooves 3m on both sides and the tip side is wider. Has become. That is, a slightly inner layer side of the groove 3j is an inverted U-shaped groove 3m that is enlarged in both directions close to the left and right inverted U-shaped grooves 3m. The peripheral walls of the opening of the linear groove 3k are formed to be in contact with each other in the state after molding. As the mold for forming the long groove 3j, the core metal 4 and the outer decomposition mold 5 are prepared as shown in FIG.
A large number of groove-forming projections 6 are fixed inside. Other configurations are substantially the same as those of the first embodiment.

In the third embodiment, since the long groove 3j is formed by the cut groove, the gripping feeling of the outer surface 3a becomes good and the absorption of water becomes good. Also in the first and second embodiments, a mold having substantially the same shape as that of the third embodiment is used. Further, although the grooves 3b, 3e and 3j in the first, second and third embodiments are formed long in the axial direction of the grip, the direction and shape of the grooves are not limited to this. For example, the groove may be formed in the grip circumferential direction or another direction, or may be dimple-shaped without being formed long.

[0017]

Since the present invention has been configured as described above,
When the outer surface of the grip is gripped, the part of the opening of the groove that directly touches the hand does not deform, and the feel is good, and the groove on the inner tip side on the inner layer side slightly deforms according to the weight of the gripped hand. As it is easy to do, it will be a grip that fits in your hand. In addition, the grip absorbs moisture adhering to the outer surface when it rains or when sweating, and is absorbed in the groove and stored in the volume of the groove at the inner tip, so to prevent moisture from returning properly. Thus, it is possible to provide a grip of a golf club which has excellent effects such as prevention of slippage due to water.
