Spherical particles or fibrous amorphous carbon are mixed into the prepreg as a supplement. Thereby, the wear resistance of the surface layer of the fishing rod with which the human hand or the fishing line comes in contact is improved, and the weight can be reduced. In FIG. 4, reference numeral 43 indicates an intermediate main body layer.

As another mode of applying the sporting goods member of the present invention to a fishing rod, as shown in FIG. 5, a surface coating layer 53 formed on an undercoat layer 52 on a rod pipe main body layer 51 is used. Amorphous carbon 54 in the form of spherical particles is mixed. This is performed by mixing spherical particulate amorphous carbon into the paint used for forming the surface coating layer 53. Thereby, the same effect as above can be obtained. In particular, as shown in FIG.
By exposing from 3, the wear resistance can be improved and the anti-slip effect can be exhibited without damaging the hand.

When amorphous carbon is used for a rod or a guide, it often hits rocks or the ground during use. Therefore, an amorphous carbon or a layer containing amorphous carbon is arranged in such a place where collision frequency is high. It is desirable to consider the shape and shape.

(Embodiment 2) A case where the member for sports goods of the present invention is applied to a reel will be described. FIG.
It is the schematic which shows the spinning reel of the rotor drag system using the member for sports goods of this invention. FIG.
FIG. 7 is a sectional view of the spinning reel shown in FIG. 6. In the figure, reference numeral 61 denotes a handle. The handle 61 is attached to a handle shaft 63 rotatably supported by a ball bearing 62. A drive gear 64 is attached to the handle shaft 63, and a pinion gear 65 extending in a direction orthogonal to the handle shaft 63 and rotatably supported by the ball bearing 62 is meshed with the drive gear 64. .

A rotor 67 having a bail arm 66 and a fishing line guide device (not shown) is attached to the tip end of the pinion gear 65.
And is driven to rotate via a pinion gear 65.

The drive gear 64 is connected to an oscillating mechanism (not shown). The oscillating mechanism is engaged with a spool shaft 69 which is inserted through the inside of the pinion gear 65 and is supported so as to be able to reciprocate in the axial direction.
9 is reciprocated in the axial direction. A spool 70 around which a fishing line is wound is attached to the tip of the spool shaft 69, and reciprocates in the axial direction integrally with the spool shaft 69.

As a result, when the handle 61 is rotated, the rotor 67 is driven to rotate, the spool 70 reciprocates in the axial direction, and the fishing line passes through the spool 7 via the fishing line guide device.
It is wound evenly to zero.

On the other hand, by operating the summing lever 73 rotatably supported by the reel mounting leg 71 via the support portion 72 in the direction of the arrow against the urging force of the holding spring 73a, the summing lever 73 faces the lever 73. The brake shoe 74 provided at the position moves in the direction of the arrow, and clamps a braking plate 75 that rotates integrally with the rotor 67 between the pressing plate 76 and applies a braking force to the rotor 67 by frictional force. I do.

In the drawing, a lever 77 provided at the rear of the reel body is connected to a reverse rotation prevention device for the rotor 67. By operating this lever 77,
The rotor 67 is switched between a forward / reverse rotation state and a reverse rotation prevention state. The spool attachment / detachment mechanism 78 is operated when attaching / detaching the spool 70 at the time of maintenance or the like.

FIG. 8 is a schematic view showing a spool drag type spinning reel using the sports equipment member of the present invention. 8, a spool 82 is rotatably supported at the tip of a spool shaft 81, and the spool 82 is integrally formed with the spool shaft 81 by a frictional force of a drag disk 83 having a washer and a braking plate. From a rotatable state, it is continuously adjusted to a free rotation state. The adjustment of the frictional force is performed by rotating the drag knob 84. In FIG. 8,
Reference numeral 85 indicates a rotor, and reference numeral 86 indicates a handle.

In the reel having the above structure, the shaft and bearing such as the spool shaft and the handle shaft can be made of amorphous carbon or a material containing amorphous carbon. Thereby, the wear resistance of these members is improved, and a lightweight reel can be realized.

The ball of the ball bearing and the receiving member for receiving the ball may be made of amorphous carbon or a material containing amorphous carbon. Thus, a ball bearing having wear resistance can be obtained. In addition, this ball bearing can increase the sphericity of the ball by polishing, and the rotation is smooth. In addition, such a ball bearing can be applied to a general mechanical device other than the reel. In particular, since it is excellent in abrasion resistance and can prevent the generation of harmful substances such as rust and is safe, it can be used for toys and the like.

A member which comes into contact with the fishing line, such as a spool front surface portion such as a spool or a spool ring for guiding the fishing line, a line guide (for bait reel or a reel with a body), a line roller, etc., is made of amorphous carbon. Alternatively, it can be made of a material containing amorphous carbon. This reduces the yarn resistance of these members,
In addition, the wear resistance can be improved and the weight can be reduced.

A disk body of a drag device or a summing device, gears such as a drive gear, a pinion gear, and a worm gear, and a worn or slidable member such as an oscillating slider may be made of amorphous carbon. It can be composed of a material containing carbon. Thus, the wear resistance of the member can be improved while reducing the weight. In addition, lubricity can be improved, and oil-less operation is possible. In addition, since the amorphous carbon does not absorb moisture or oil, it is possible to prevent the members from changing over time or reducing the performance. Further, with respect to the disk body, the difference between the dynamic friction coefficient and the static friction coefficient can be reduced by, for example, making the surfaces of these members mirror-like, so that stable braking performance can be exhibited.

Further, members such as the drag knob and handle knob of the reel, the spool and the rotor, the body and the body cover can be made of amorphous carbon or a material containing amorphous carbon. In this case, the above member may be applied with a paint containing amorphous carbon to form a film containing amorphous carbon. As a result, the wear resistance of the surface exposed to the outside can be improved, and the weight can be reduced.

(Embodiment 3) A case where the member for sports goods of the present invention is applied to a golf club will be described.

FIG. 9 is a schematic view showing a golf club using the sports equipment member of the present invention. In the figure, reference numeral 91 denotes a club shaft formed of a tubular body formed by winding a fiber-reinforced prepreg obtained by impregnating a synthetic resin into aligned reinforcing fibers. The club shaft 91 has a shape such that its diameter is reduced from one end to the other end. A grip 92 is attached to the end of the club shaft 91 on the large diameter side. A reinforcing ring 93 is attached to a mounting portion of the grip 92.

On the other hand, a club head 95 is attached to the end on the small diameter side of the club shaft 91 via a socket 94. A face 96 made of, for example, a metal having a high specific strength is attached to the club head 95. An adjusting body 97 composed of a shaft reinforcing ring and a weight adjusting member is provided slightly larger in diameter than the center of the club shaft 91.

In the golf club having the above configuration,
The socket, the reinforcing ring of the grip, the grip, the spacer for filling between the grip and the shaft, the shaft reinforcing ring, and the decorative parts of the head and the shaft can be made of amorphous carbon or a material containing amorphous carbon. Thereby, the wear resistance of these members is improved, and a lightweight golf club can be realized.

The head may be made of amorphous carbon or a material containing amorphous carbon. In this case, the characteristics can be controlled while maintaining the lightness and durability of the amorphous carbon by using it in combination with another member having a large specific gravity. That is, since the specific gravity of the amorphous carbon is small, the high specific gravity members can be distributed freely and more than usual. As a result, it is possible to realize a golf club having a feature in which the sweet spot is enlarged and the position of the center of gravity is adjusted up and down, left and right, front and back, and the like.

Here, the member having a higher specific gravity means a member made of a material having a higher specific gravity than amorphous carbon. Examples of such a material include titanium, stainless steel, copper, brass, lead, beryllium, and tungsten. The material to be combined with the amorphous carbon is optional, but the specific gravity is desirably 3.0 or more, preferably 6.0 or more.

When used as a head, the main part of the head may be formed of amorphous carbon, and may be used for a face, a back face, or only a part thereof. At this time, the place, range, amount, and the like to be used can be freely selected.

The shaft may be made of amorphous carbon or a material containing amorphous carbon. In this case, it is used as a complementary material of the fiber reinforced prepreg. For example, it is used for the layer of the inclined sheet to improve the torsional strength, and is used for the outer layer to improve the wear resistance. In addition, the appearance can be improved by arranging the fibers in a twill shape using amorphous carbon fibers.

Further, abrasion resistance can be improved by mixing amorphous carbon into a coating or printing material used for a golf club and forming a coating using the same. Such a member for sports goods of the present invention can prevent the occurrence of peeling, breakage and deterioration in performance even when used outdoors and left in a temperature change or in nature. In addition, since amorphous carbon can have a smooth or mirror-like surface, the appearance can be improved.

When the amorphous carbon is exposed to the outside, TiN, TiC, TiO ₂ ,
A protective layer such as TiAlN, diamond-like carbon or a metal coating (Ni plating layer, chromium plating layer, etc.) may be formed to further improve the impact resistance. Furthermore, it is not limited to the protective layer, and may be covered with a plate-like component or the like. Of course, this can be applied to all the embodiments described above.

In the above-described embodiment, the case where the member for sports equipment of the present invention is used for fishing equipment, golf equipment, and other fishing equipment, for example, a cooler, an ayu boat, a rod receiver, and the like has been described. The present invention is not limited to this, and can be applied to sports equipment having a portion where wear or damage is likely to occur, such as a place where members come into contact with each other or a place where human members come into contact, for example, tennis equipment and ski equipment. Can be.

[0053]

As described above, the member for sports goods of the present invention wears amorphous carbon because it uses amorphous carbon as the reinforcing fiber of the fiber-reinforced prepreg constituting at least the region in contact with other members and the tubular body. It is difficult to damage and it can be prevented from being damaged. Moreover, the member for sports goods of the present invention can achieve the above-mentioned effects and can achieve weight reduction.
