Description

  The present invention relates to a golf club provided with a decorative body.

  As a decorative body applied to a conventional golf club, a socket ring (ferrule) is formed by fixing a decorative ring having a diameter substantially concentric and concentric with the socket pipe at an appropriate position in the axial cross section of the socket pipe. It is known that a small pipe part, a transparent synthetic resin large-diameter pipe part fitted in the small pipe part, and a metal color intermediate layer interposed between the small pipe part and the large-diameter pipe part are integrated. (See Patent Document 1).

  Further, a silver nitride layer formed by silver nitride treatment on the whole or a part of the surface of the golf club head, a base coat layer formed on the surface of the silver nitride layer, and an ink jet on the surface of the base coat layer It is also known that a decorative layer including an ink jet printing layer formed by printing is formed, and a transparent or translucent protective layer is formed on the surface of the ink jet printing layer (see Patent Document 2).

Furthermore, there is also known one in which a relief pattern is formed integrally with a metal of the head body in a cavity formed on the back surface of the head body. The relief pattern is a pattern of an animal such as a lion, and is formed integrally when the head body is cast or forged (see Patent Document 3).

  The thing of patent document 1 uses the ring provided in the ferrule as a decoration body, and as a decoration body, it is not what attracts a human eye, and the decoration effect was low. Moreover, although the thing of patent document 2, 3 has a high decoration effect, its manufacturing cost is also high. Furthermore, any known technique is manufactured at the time of manufacturing a golf club, and cannot be applied to an existing golf club according to the user's preference.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a golf club that is low in cost, has a high decorative effect, is remarkably eye-catching, and can be applied to any golf club after manufacture.

  In the present invention, the reflective particles are adhered to a desired part of the golf club to form a decorative body. Therefore, the reflective particles, for example, rhinestones are brilliant and can attract a lot of attention. In addition, the decorative body is not applied in the manufacturing process of the golf club, but can be easily retrofitted to the existing manufactured golf club, so that the decoration according to the individual preference of the user is applied at low cost. be able to.

  FIG. 1 shows an iron golf club, in which a plurality of reflective particles 2 are bonded to desired portions of the back surface 1A of the head body 1 to form a floral decorative body 10. FIG. A decorative body 10 in which the reflective particles 2 have a desired pattern or pattern can be bonded to the hosel 3 formed integrally with the head body 1. A shaft 4 is inserted into the hosel 3 and a ferrule 5 is mounted in the vicinity of the insertion portion of the shaft 4.

  FIG. 2 shows an example in which a decorative body 10 is bonded to the ferrule 5, and this ferrule 5 is also provided with a decorative ring 5A similar to the conventional one. What is optimal as the reflective particles 2 constituting the decorative body 10 is called rhinestone. The name of the rhinestone is said to have come from cutting the crystal taken from the Rhine, but now it is called rhinestone, including diamond-cut crystal glass (lead glass), and is widely used as glass. This is an imitation jewel. There are various colors such as blue, red, green and purple mixed with gold, iron and manganese. The use of a metal with a rhinestone on the back to increase reflection makes it more sparkling and attracts people's eyes. In addition to the rhinestones, reflective particles 2 made of transparent resin or metal can also be used.

  In the embodiment described above, the decorative body 10 in which various patterns are formed by directly adhering the reflective particles 2 to a desired portion of the golf club is formed. However, as shown in FIG. The decorative particles 10 can be formed by adhering the active particles 2 and the sheet 6 can be adhered to a desired portion of the golf club. An adhesive layer 7 is provided on the back surface of the sheet 6, the surface of the adhesive layer 7 is covered with a release sheet 8, the release sheet 8 is peeled off and the sheet 6 is adhered to a desired part of the golf club with the adhesive layer 7. it can. As shown in FIG. 4, for example, when the seal 6 is bonded to the back surface 1 </ b> A of the head body 1, a double-sided adhesive tape can be used. The double-sided pressure-sensitive adhesive tape is provided with adhesive layers 7 and 7 ′ on both surfaces of the substrate 9. When a material using acrylic foam is used as the base material 9 and pasted on the back surface 1A of the head body 1, the shock resistance of the acrylic foam that forms the base material 9 when the impact of hitting a ball is transmitted to the head body 1 Therefore, vibration absorption is excellent and adhesion peeling can be prevented.

  FIG. 5 shows an example in which the concave portion 11 is formed in the ferrule 5 where the decorative body 10 of the golf club is bonded, and in this example, the reflective particles 2 are bonded to the concave portion 11. In the case of the sheet 6, the recess 11 corresponding to the size of the sheet 6 is formed, and the sheet 6 on which the decorative body 10 is formed is bonded to the recess 11.

  Adhesion of the reflective particles 2 is performed by providing an adhesive on the adhesive surface of the particles 2, pressing the tip of the ultrasonic bonding machine from above the particles 2 to melt the adhesive, and golfing the reflective particles (rhinestone) 2. A method of adhering and fixing to the club or the sheet 6 can be adopted. As an adhesive provided on the particles 2, a polyamide-based adhesive is preferably used when an ultrasonic bonding machine is used. When the sheet 6 is formed of fabric or knitted fabric, the adhesive melted by the ultrasonic bonding machine penetrates into the gaps between the fibers, and the particles 2 are surely fixed to the sheet 6.

  Resin particles and metal particles can also be used as the reflective particles 2 other than rhinestones. Since the metal particles generally have a higher specific gravity than the resin, a resin particle coated with a metal film can be used instead. The metal that forms the coating is preferably aluminum or titanium. As the resin, any resin having transparency can be used, but an acrylic resin having high transparency and less discoloration is particularly preferable. A general urethane resin is preferable because it has flexibility, but it is preferable to use a urethane resin of a type that does not easily yellow because it turns yellow over a long period of time. The metal particles are preferably aluminum or titanium having a relatively small specific gravity, and a metal film may be provided on the resin. For example, by applying aluminum coating on urethane-based elastomer or titanium coating on acrylic resin, it can have a metallic luster and can be made gorgeous. The other side of the adhesive surface has a curved surface like a part of a spherical surface, or has multiple cut surfaces such as diamond cuts, so that it can look beautiful using the reflection of light. .

  When the concave portion 11 is provided, the depth of the concave portion 11 is taken into consideration so that the adhesion surface of the particle 2 is not caught when the golf club is pulled out of the caddy bag, for example, and the particle 2 is stuck in the concave portion 11. It is desirable that In particular, providing a groove on the periphery of the ferrule 5 is preferable because it looks good. However, if the groove is deeply dug so that the thickness of the groove is 0.5 mm or less, care must be taken because the thin part may break when inserted from the tip of the shaft. Such a groove becomes the recess 11. When the depth of the concave portion 11 is in the range of 0.2 mm to 2 mm and the concave portion 11 is a circumferential groove, the width is about 2 mm to 5 mm. If the width is too narrow, it will be difficult to affix the particles 2, and if the width is too wide, it will be easily caught on the joint between the ferrule 5 and the particles 2, which is not preferable. If it is narrow, the particles 2 cannot be attached. When the depth of the groove is deep, it becomes difficult to stick. This is because if the depth is shallow, the particles 2 are easy to hit and peel off easily. Therefore, the depth of the groove may be such that the pasted portion is hidden, but it is preferable that the depth of the particle 2 is deeper.
