[0001]
BACKGROUND OF THE INVENTION
The present invention relates to fishing / sports equipment, and more particularly to fishing equipment such as fishing rods, or sports equipment such as golf shafts and tennis rackets.
[0002]
[Prior art and problems]
For example, from Japanese Patent Laid-Open No. 11-289924, a carbon prepreg is wound to form a brazing material, and a hue change coating film layer made of a synthetic resin including multilayer fine flakes is formed on the surface of the brazing material. Fishing rods are known that can change the hue of the to obtain a brilliant decorative effect. In order to form such a bright decorative effect, the multilayer fine flake has a five-layer structure in which a transparent interference layer and a semi-transparent metal absorbing layer are arranged in order on both sides of the opaque metal reflective layer, respectively. The thickness (maximum width) is about 10 to 70 μm, the thickness is about 1 to 3 μm, and the hue change coating film layer is formed by being contained in the urethane resin.
[0003]
In this hue change coating film layer, the multilayer fine flakes are thin, and are uniformly dispersed along the thickness direction. For this reason, the inner multilayer fine flakes arranged in the portion close to the brazing material are shielded from light by the multilayer fine flakes arranged outside. For this reason, the entire color is varied, and the multi-layered thin flakes located in the vicinity of the eaves are not conspicuous and become dull, and the decorative effect is impaired.
[0004]
The present invention has been made based on such circumstances, and it is possible to make the interference color due to the interference effect of light stand out clearly and to produce an excellent decoration effect due to suitable glitter. The purpose is to provide sports equipment.
[0005]

[0006]
DETAILED DESCRIPTION OF THE INVENTION
1 to 5 show a preferred embodiment of the fishing / sports equipment according to the present invention. In the illustrated embodiment, the fishing / sporting equipment is formed as a tubular body 10 suitable for a fishing rod or a golf shaft.
The tubular body 10 of the present embodiment has a hollow thin-walled tubular main body 12 formed by winding a prepreg in which a reinforcing fiber is impregnated with a synthetic resin around a core metal, and the surface of the main body 12 A decorative layer 14 including particles to be described later is formed at a required portion of the part.
[0007]
As shown in FIG. 2, the main body 12 of the present embodiment has an innermost layer 12a formed by aligning reinforcing fibers in the circumferential direction, and the reinforcing fibers aligned in the axial direction on the outer peripheral surface of the innermost layer. It is formed as a multilayer structure including the formed intermediate layer 12b and an outermost layer 12c formed by aligning reinforcing fibers in the circumferential direction on the outer peripheral surface of the intermediate layer. The main body portion 12 of the present embodiment has the intermediate layer 12b formed to be the thickest, and the intermediate layer 12b is sandwiched between the innermost layer 12a and the outermost layer 12c and reinforced, thereby enabling large bending. Can withstand a large axial tensile force.
[0008]
Of course, in addition to such a three-layer structure, the main body 12 may be formed in a single layer or a two-layer structure depending on the application, and further formed in a multilayer structure of four layers or five layers or more. Also good. Moreover, the main-body part 12 is not restricted to the hollow tubular structure as shown in figure, A solid structure may be sufficient and the external shape can be formed in a suitable polygonal shape. And the material which forms the main-body part 12 is not restricted to the above fiber reinforced resin, It can form with suitable materials, such as a metal or a ceramic, according to the use of fishing goods or sports goods. In any case, the outer peripheral surface of the main body 12 is preferably formed in a smooth mirror surface by, for example, barrel polishing or buffing.
[0009]
As shown in FIGS. 2 and 3, the decoration layer 14 formed at a required portion of the surface portion of the main body portion 12 is formed on the base layer 16 of the main body portion 12 and is covered with a protective layer 18. By this, it is protected from the external environment. The decoration layer 14 may be formed over the entire surface portion of the main body 12. When the decoration layer 14 is formed only on a part of the surface, as shown in FIG. It is preferable to apply step coating.
[0010]
The underlayer 16 is formed on the entire surface portion or a required portion of the outermost layer 12c of the main body portion 12 by suitable means such as painting or plating. The base layer 16 protects the main body 12 and enhances the adhesion of the decorative layer 14. For example, the main body 12 made of fiber reinforced resin having carbon and glass fibers as shown in FIG. When the outer diameter is approximately 3 to 25 mm and the thickness is approximately 0.1 to 3 mm, the thickness of the underlayer 16 is preferably approximately 5 to 60 μm. By forming in this way, it is difficult to peel off even if the main body 12 is deformed, and the base layer 16 having excellent adhesion is formed. Further, the underlayer 16 is colored in a suitable color that makes the particles 20 in the decoration layer 14 noticeable, such as black or silver, and the outer peripheral surface is smoothed in order to form the decoration layer 14 satisfactorily. It is preferable to form a mirror surface. The underlayer 16 may be formed in a plurality of layers including an impact absorbing layer, a primer layer, a synthetic resin layer, or the like, and the underlayer 16 is omitted and the decoration layer 14 is replaced with the main body 12. It is also possible to form it directly on the surface of the substrate.
[0011]
The underlayer 16 is excellent in adhesion with the main body 12 and desirably follows the bending of the main body 12 and the deformation of the cross section accompanying the bending, and is suitable for such an underlayer 16. For example, an epoxy resin, a polyurethane resin, a fluororesin, an acrylic silicone resin, an acrylic urethane resin, an acrylic resin, or a wet paint is preferable, and the coating film hardness is preferably in the range of pencil hardness 2B to 4H. .
[0012]
The decorative layer 14 of the present embodiment formed on the underlayer 16 is a clear layer made of a transparent or translucent synthetic resin such as epoxy, polyurethane, fluorine, acrylic silicone, acrylic urethane, acrylic, or water. It is formed to a thickness of, for example, 25 to 90 μm by a paint or a color clear paint. The decorative layer 14 contains particles 20 that generate interference colors and is stably held.
[0013]
As shown in FIG. 2 to FIG. 5, the particles 20 in the present embodiment have a plate-like structure, and are dispersedly arranged in the decorative layer 14 with the surface portion thereof substantially along the peripheral surface of the main body portion 12. Has been. These particles 20 are preferably formed from metal. In the case of forming with such a metal, it can also be formed with a metal compound composed of a metal such as a metal oxide and an element other than the metal. As such a metal material, gold, silver, aluminum, an aluminum alloy, copper, tin, chromium, cobalt, brass, iron, stainless steel, nickel, zinc, or the like can be used. Moreover, it can also be made from the composite material formed in the particle | grains 20 of the plate-like structure with a random shape by forming a metal film on a resin film (for example, PET etc.) and crushing this resin film small. In any case, the particle 20 has a plate-like structure having a surface portion size, that is, a maximum dimension of about 50 to 200 μm and a thickness of about 10 to 30 μm when viewed in the plan view shown in FIG. It is preferable to form it.
[0014]
Further, as shown in FIG. 5, the surface portion of the particle 20 is formed as a fine concavo-convex surface in which a large number of fine grooves 22 are extended adjacent to each other. The pitch of these grooves 22, that is, the interval between adjacent grooves 22 is preferably 0.3 to 1 μm, and the depth is preferably ½ or less of the thickness. In the present specification, the groove 22 includes not only a groove formed by being recessed on a flat surface but also a recess formed between ridges protruding from the flat surface. Is equal to the interval between adjacent ridges, and the depth of the groove 22 is equal to the height of the wall or ridge that defines the groove 22. Such a groove 22 is formed by, for example, pressing a surface portion of a metal foil or at least one surface portion of a resin film coated with a metal film with a press machine, for example, and innumerable fine linear irregularities on the surface portion. It can form by the embossing which forms a part. The particles 20 that have been subjected to such embossing on the surface portion form an interference color due to interference at the concavo-convex portion of the surface portion.
[0015]
Such a particle 20 has a relatively large outer shape with a surface portion size of about 50 to 200 μm with respect to the decorative layer 14 formed to have a thickness of about 10 to 30 μm as described above. 20 are easily arranged in the decorative layer 14 in a state where the surface portion thereof is substantially along the peripheral surface of the main body portion 12. In other words, in order to arrange the surface portion of the particle 20 as far as possible toward the outside of the tubular body 10, the thickness of the decoration layer 14 is equal to or greater than the average thickness of the particle 20. It is preferably 2.5 times or less, and particularly preferably 2 times or less the average thickness of the particles 20.
[0016]
By forming the decorative layer 14 to such a thickness, the particles 20 having a large plate-like structure are arranged in the decorative layer 14 so that the surface portion is substantially along the peripheral surface of the main body portion 12. The surface portion of the particle 20 can be directed outward from the main body portion 12. For this reason, the interference color by each particle 20 is efficiently emitted outside the tubular body 10. As shown schematically in FIG. 3, each particle 20 is arranged at various angles in the decorative layer 14, so that various interference colors are formed when viewed from one direction with respect to the tubular body 10. In addition, since the decorative layer 14 is formed relatively thin with respect to the thickness of the particle 20, the tubular body 10 is formed in a lightweight structure, and the surface portion of the particle 20 is in the vicinity of the outer peripheral surface of the decorative layer 14. A noticeable granular pattern is formed. When the tubular body 10 is moved, or when the viewing direction is changed variously, the interference color formed by these particles 20 changes variously, thereby producing a very excellent decorative effect with glitter. .
[0017]
FIG. 4 is an enlarged view of the decorative layer 14 as viewed from the outside of the tubular body 10 and shows a state where the particles 20 are dispersedly arranged. The various line patterns applied to each particle 20 show different colors that can be seen when observed along one direction from the outside of the tubular body 10. The color of the particles 20 in the decoration layer 14 is not only the interference color in the uneven portion of the surface portion of each particle 20 but also the interference in the layer thickness from the surface portion of each particle 20 to the outer peripheral surface of the decoration layer 14. Interference colors due to action are also included. For this reason, even when viewed from one direction of the tubular body 10, a large number of particles 20 individually form various colors, thereby producing a decorative effect with extremely excellent glitter.
[0018]
Further, in the decorative layer 14, it is preferable that approximately half or more of the particles 20 are spaced apart from the adjacent particles 20 by a distance exceeding twice the average size of these particles. In this case, in the absence of the underlayer 16 or the underlayer, the adhesion of the decoration layer 14 to the main body 12 is increased, and the durability can be improved. Such an increase in the adhesion of the decorative layer 14 is extremely preferable from the viewpoint of preventing peeling due to bending, for example, when the tubular body 10 is formed as a fishing rod. Even in the case where a large space is formed between the adjacent particles 20 as described above, each particle 20 itself is large and the surface portion is disposed substantially outward. Is not conspicuous and the decorative effect with glitter is not reduced.
[0019]
In order to form the glittering decorative layer 14 by mixing the particles 20 in the decorative layer 14 as described above, an appropriate method can be adopted. For example, a coating made of the above-described synthetic resin for forming the decoration layer 14 is applied in advance, and the particles 20 are mixed in a semi-cured state, and then cured or further coated with a coating. It can also be cured. Of course, the decorative layer 14 may contain the particles 20 by any other suitable method, and the thickness of the decorative layer 14 is equal to or greater than the average thickness of the particles 20 and 2.5 times the average thickness of the particles. It is obvious that any method can be used as long as it can be formed to be twice or less. For example, such a decorative layer 14 can be formed by screen printing using ink in which particles 20 are mixed in advance.
[0020]
In the present embodiment, such a decorative layer 14 has a smooth mirror surface on the outer peripheral surface, and is protected from the external environment by a protective layer 18 formed thereon. The protective layer 18 of the present embodiment includes a sealing layer 18a and a clear layer 18b. The sealing layer 18a improves the adhesion between the decorative layer 14 and the clear layer 18B, and the outer peripheral surface of the decorative layer 14 is improved. Smooth. The sealing layer 18a is preferably made of a transparent or translucent synthetic resin such as epoxy, polyurethane, fluorine, acrylic silicone, acrylic urethane, or acrylic in consideration of adhesion to the decorative layer 14. The clear layer 18b may be color clear, and is preferably formed of fluorine, polyurethane, acrylic silicone, acrylic urethane, or acrylic resin in consideration of weather resistance or corrosion resistance.
[0021]
FIG. 6 shows various shape examples of the particles 20.
A particle 20A shown in FIG. 6A has a substantially hexagonal shape, a particle 20B shown in FIG. 6B has a star shape, and a particle 20C shown in FIG. 6C has a heart shape. As described above, these particles 20A, 20B, and 20C preferably have fine irregular surfaces formed on the surface portion by countless fine grooves 22. These particles 20A, 20B, and 20C can be used alone, but can also be used in appropriate combination with particles having random shapes as shown in FIGS. Of course, in addition to the shape shown in FIG. 6, an appropriate shape can be used within the above-mentioned size range.
[0022]
FIG. 7 shows a tubular body 10A according to another embodiment. Since the tubular body 10A of the present embodiment is substantially the same as the tubular body 10 according to the above-described embodiment, the same portions are denoted by the same reference numerals and the description thereof is omitted.
[0023]
In the tubular body 10 </ b> A of the present embodiment, a base layer 16 </ b> A applied to the outer peripheral surface of the main body 12 is formed by a metal thin film layer 24 formed by appropriate means such as plating or vapor deposition, and a required portion of the metal thin film layer 24. The color clear layer 26 is provided. The color clear layer 26 is formed of a translucent synthetic resin such as black or red, for example, and forms a step portion protruding from the metal thin film layer 24. The decorative layer 14 is formed on the base layer 16A having such a stepped structure, and is protected from the external environment by the protective layer 18.
[0024]
According to this tubular body 10A, the metal thin film layer 24 of the foundation layer 16A imparts a metallic luster to the decorative layer 14 having excellent glitter. Further, the color clear layer 26 of the base layer 16A partially lifts the decoration layer 14 and causes light to enter the inner surface portion of the particles 20 in the decoration layer 14, thereby producing a complicated interference color. Form. At this time, the metal thin film layer 24 reflects more light, thereby causing the particles 20 to develop a bright and conspicuous color.
[0025]
The metal material suitable for forming the metal thin film layer 24 includes, for example, aluminum, nickel, chromium, titanium, or stainless steel, and the material for forming the color clear layer 26 is the decorative layer 14. In consideration of the adhesiveness, a paint using a resin such as epoxy, acrylic silicone, silicone, acrylic urethane or the like is preferable, and the hardness is preferably about 2B to 4H in pencil hardness.
[0026]
As mentioned above, although various embodiment of this invention was described, this invention is not limited to any embodiment, A various deformation | transformation or change is possible. For example, the color clear layer 26 of the base layer 16A shown in FIG. 7 can be provided on the base layer 16 of the tubular body 10 shown in FIGS. 2 to 5, and such a color clear layer 26 is provided as a decoration layer.
