[Technical field to which the invention belongs]

 The present invention relates to a golf club.

[0002]

[Prior art]

 In golf, the goal of a player is to hit a golf ball at a distance. Distance is an important influencing factor in the golf club itself, in addition to the competitor's own skills. Traditionally, golf clubs are made of steel, but instead of steel, golf clubs made from graphite, for example, are not only lighter, but also have greater operating force and flexibility than steel golf clubs. . In addition, the flight distance can be extended. Benefits include reduced impact on the arms, joints, shoulders, or elbows. However, it has disadvantages such as high manufacturing cost, large torsion and high breakage rate.

[0003] Graphite golf clubs are usually manufactured by coating a thin section or by winding with a thin thread. In the former method of coating a flake, a fiber such as a carbon fiber or a glass fiber is immersed in a resin or the like, and then left in a parallel mold to form a plate or an infiltrated coarse material. The infiltrated coarse material is cut into small flakes. To form a plurality of flake layers, conical flakes are wound around a central axis. Each fiber forms an angle between 0 ° and 90 ° with the central axis. After the flake layer has hardened, the central axis is removed.

[0004] In the latter method of winding with a fine thread, fibers are bundled, and each bundle is immersed in resin and wound around a central axis. The rod is uniform and lighter than conventional metal rods because a flake layer is formed before curing and shaping.

[0005] A preferred golf club is one in which the rod and head are adjustable according to the user. Golf clubs are designed with consideration for center of gravity, balance, torsion, hitting force, and flexibility. A rod wound with a fine thread has a high breakage rate. Also, the center of gravity, balance, torsion, hitting force, and flexibility of the aforementioned golf clubs are interrelated. For example, increasing the content of carbon fiber gives the golf club a favorable weight, but the golf club becomes thicker and affects hardness and balance.

[0006]

As shown in FIG. 3, the flake layer 22B and the flake layer 22C are further wound. As shown in FIGS. 4 and 5, the flake layer is wound around the central axis 15 at a larger angle to obtain a predetermined thickness and center of gravity. Short flake layers, such as flake layer 22C, are used at assembly site 12 to enhance the polished portion or provide a larger size. As shown in FIG. 6, after coating the flake layers 22, 22A, the elongated flake layer 22B, and the short flake layer 22C at different angles, the elongated flake layer 22B and the short flake layer 22C are further wound, and the six flake layers are formed. Form. The arrangement angle of the fibers in the flake layer can be selected from 0 ° or more and 90 ° or less with respect to the longitudinal axis direction of the central axis. Flake layers with longitudinal fibers have a significant effect on flexibility and bending force. Further, golf clubs manufactured by a flake coating method are usually irregular.

As shown in FIGS. 7 and 8, a golf club manufactured by winding a thin thread is obtained by winding one or more fiber bundles 24 in place of the thin layer 22 around the central axis 15 in a double-layer manner. Form a layer. At this time, the fiber bundle 24 maintains a predetermined angle with respect to the central axis 15. The fiber bundle 24 is composed of a plurality of fibers. The fiber bundle 24 is composed of, for example, 12,000 fibers.

A fiber bundle 24 is wound around a golf club. Thereafter, the fiber bundle 24 is wound around the golf club with the winding direction reversed and the angle with respect to the center axis reversed to form a special flake layer. Since the winding of the fine thread is controlled by a computer, not only can the winding angle be controlled precisely, but also the thickness of the layers can be adjusted and the position of the individual fibers can be changed. To control the center of gravity and flexibility, the winding of the fine thread may employ different corrugations, styles. It is to be noted that the winding of a thin thread provides higher uniformity than the coating method of the flake.

FIG. 9 shows a second embodiment of the present invention. As shown in FIG. 9, the central axis 15 is covered with the flake layer 22 to form a core. A plurality of layers are formed on the outer layer of the core by winding the fiber bundle 24 by a thin yarn winding method. The composites have better properties than those formed using a flake layer coating or a thin thread winding alone.

[0013] Common fibers are made from graphite, glass, or other known materials. Further, a thin thread is formed as necessary, or a thin section is formed with a parallel resin mold. In the case of flakes, different metals with various properties, such as brass, nickel, etc., are provided at different locations in the parallel resin mold to provide different centers of gravity, forces, shock absorption and the like.

[0014] The metal coating may apply vaporized metal vapor to the fiber. Alternatively, it may be plated. Metals for metal coating include nickel, titanium, platinum, zinc, copper, tungsten, cobalt, gold or silver. The metal is applied to the fiber with a thickness of 400 A ° or more and 2.5 μm or less according to a predetermined center of gravity and appearance by winding or coating the fiber. The metal-coated fiber contains 0% by weight or more and 99% by weight or less of metal. The preferred range is 10% to 60% by weight, and the flake layer preferably contains 40% to 45% by weight, and the thin-wound layer preferably contains 20% to 26% by weight of metal. .
