Description

  The present invention relates to a tubular body used for fishing rods, golf shafts, and the like, and more particularly to a tubular body having a tubular body body made of fiber reinforced resin and a method for manufacturing the same.

  In general, Japanese rice bran, which is preferred as a spatula, is formed through a number of complicated processes, such as drying natural bamboo over a long period of time, repairing the habit, and grinding the knot portion smoothly. On the surface of such natural bamboo, lacquer is applied to form an appearance that takes advantage of the luster of natural bamboo. Such Japanese rice cakes form extremely excellent functions and appearance as a spatula, but are expensive. For this reason, various fishing rods have been proposed which are formed by emphasizing the characteristics of natural bamboo on the outer surface of a main body made of fiber reinforced resin.

  In order to produce a tubular body that gives an impression very similar to that of natural bamboo at a low cost, a ground color layer having a ground color of bamboo and a large number of streaks along the longitudinal direction is formed on the surface of the tubular body. Later, a method of forming an inclined blurred pattern by spraying a paint having a lightness different from the ground color of the ground color layer while moving the nozzle for spray coating in the longitudinal direction while rotating the tubular body ( For example, see Patent Document 1).

In addition, on the ground color layer formed on the surface of the tub tube, a spot pattern layer of a color different from the ground color having a thickness that allows the ground color to be seen through is formed, and this spot pattern layer is formed. Before or after the fishing rod has been developed, a number of streak patterns are formed over the entire circumference of the rod tube and have a pattern very similar to bamboo (see, for example, Patent Document 2).

  However, even when a pattern very similar to bamboo is formed on a tubular body made of fiber-reinforced synthetic resin, it is extremely difficult to bring out the texture of the surface of natural bamboo and the appearance such as gloss. is there.

  The present invention has been made based on such circumstances, and an object thereof is to provide a tubular body having a more natural bamboo feeling in appearance.

  In order to achieve the above object, according to the present invention, a ground color layer formed with a ground color of bamboo on the outer surface of a tubular body body made of fiber reinforced resin, and along the longitudinal direction outside the ground color layer. There is provided a tubular body in which a pattern layer having a streak pattern and a transparent or translucent coating layer having a fine linear pattern outside the pattern layer are formed.

  Furthermore, on the outer surface of the tubular body body made of fiber reinforced resin, a ground color layer formed with a bamboo ground color and a pattern layer having a streak pattern along the longitudinal direction outside the ground color layer in order. A method for manufacturing a tubular body is provided that forms and then forms a transparent or translucent coating layer having a fine linear pattern outside the pattern layer.

  According to the present invention, the ground color layer and the pattern layer formed on the outer surface of the tubular body body form a pattern very similar to natural bamboo, and the fine linear pattern formed on the outside of the pattern layer is a natural pattern. The texture of the bamboo surface and the appearance such as luster are formed, thereby forming a tubular body with a more natural bamboo appearance.

  Further, according to the manufacturing method of the present invention, such a tubular body having a natural bamboo feeling can be easily and reliably manufactured.

1 to 4 show a part of a tubular body 10 according to an embodiment of the present invention.
The tubular body 10 is suitable for a fishing rod such as a spatula (FIG. 1), for example, and a fiber reinforced prepreg obtained by impregnating a reinforcing fiber such as carbon fiber or glass fiber with a synthetic resin is wound around a core metal. And a tubular body body 12 (FIG. 3) made of a fiber reinforced synthetic resin formed into a hollow thin-walled structure. The tubular body 10 is not limited to such a hollow structure, and may be a solid structure. Therefore, the tubular body 10 has a tubular shape in its outer shape, and the internal structure may be either a hollow structure or a solid structure.

  As shown in FIGS. 1 and 2, the tubular body 10 is formed as a main rod of a fishing rod, and a grip portion 14 is provided on the buttock side. The grip portion 14 is provided with a grip member 16 having a large diameter that is easy to be gripped by a fisherman, and is made of, for example, wood or resin (ABS resin or nylon) at the buttock side end portion of the grip member 16. A preferable buttocks plug part 18 is attached by, for example, adhesion, and the end of the fishing rod 10 is closed. In addition, the tubular body 10 and the gripping member 16 are integrated with each other on the front side of the gripping member 16 via the shim portion 20. The grip member 16 is made of a material having a soft material with low hardness, such as cork or foamable resin, for example, and has a length that improves operability in accordance with the overall length of the fishing rod.

  In the present embodiment, the gripping member 16 has a tapered outer shape, and a fabric layer 22 in which yarns of flexible fibers such as cotton yarn, nylon, polyester, wool yarn, etc. are woven in a spiral pattern on the outer surface. Is attached as a unit. The cover member 22 exposes each thread in an inclined manner with respect to the longitudinal axis of the tubular body 10, and a recess 22 a formed by the intersection of each thread extends along the axis, thereby extending the length of the cover member 22. It also functions as a slipper in the direction and circumferential direction. Thereby, the grip part 14 which is extremely easy to grip and excellent in operability can be formed by the flexibility and anti-slip effect of the yarn.

  The tubular body 10 forming such a fishing rod not only has the appearance of the tubular body main body 12 very similar to natural bamboo, but also has a natural texture and glossy appearance on the surface of the bamboo. It is formed to have a combination. In the tubular body 10 of the present embodiment, on the outer side of the tubular body main body 12, a patterned portion 24 that forms a pattern similar to the surface of bamboo and a step coating portion 26 that is a step coating region are alternately arranged along the axial direction. It is arranged in.

  As shown in an enlarged view in FIG. 2, the patterned portion 24 includes a ground color portion 28 colored in the same color as the surface of natural bamboo, and a large number of streak patterns 30 of indefinite length along the longitudinal direction. A large number of spot-like spots 32 having an unspecified shape and colored in a color different from the ground color portion 28 are formed. Moreover, the step coating part 26 has an outer diameter larger than the maximum outer diameter of the patterned part 24, and the outer surface is formed in the smooth surface. By forming the outer surface of the step coating portion 26 to be a smooth surface, a high-quality appearance of bamboo knots formed in a Japanese style is formed, and the appearance of the patterned portion 24 described later is similar to the surface of bamboo formed. The texture can be emphasized and the appearance of the patterned portion 24 and the step coating portion 26 can be made conspicuous.

  Such a step coating portion 26 may be provided only at one place as required. However, when forming a long tubular body such as a fishing rod, two or more places are provided at a necessary interval. preferable. When three or more places are provided, it is not always necessary to form all the intervals with the same length. Like natural bamboo, the intervals near the roots are formed short, while close to the tip. You may form the node interval of a part long.

  As shown in detail in FIGS. 3 and 4, the patterned portion 24 of the present embodiment includes a decorative layer 40 including a ground color layer 34, a pattern layer 36, and a covering layer 38 on the outside of the tubular body main body 12. .

  The ground color layer 34 is colored in a suitable brown color similar to the ground color of the surface of natural bamboo, and forms the ground color portion 28 described above. The ground color layer 34 may be formed by any method as long as it is formed to a thickness that does not cause the surface color of the tubular body main body 12 to appear. Further, the pattern layer 36 formed outside the ground color layer 34 forms a streak pattern 30 and a spot-like spot pattern 32 along the longitudinal direction. These streak patterns 30 are, for example, a large number of thin linear patterns having different lengths formed in a brownish color or other colors that are darker than the color forming the ground color portion 28, and are arranged in the longitudinal direction and the circumferential direction. It is preferable that they are formed so as to be shifted from each other and arranged over the entire circumference of the patterned portion 24. The spot-like spot pattern 32 can be formed, for example, by spreading a gun-sprayed paint droplet thinly with a cloth or sponge so that the ground color layer 34 can be seen through.

  The coating layer 38 disposed outside the pattern layer 36 is formed of a transparent or translucent resin, which will be simply referred to as “transparent” below. The ground color portion 28 formed by the ground color layer 34 from the outside, and the pattern layer 36. A pattern resembling the surface of natural bamboo formed by the streaky pattern 30 and the speckled pattern 32 formed by can be visually recognized. A large number of fine linear patterns 42 extending along the longitudinal direction are formed on the outer surface of the covering layer 38.

  If the fine linear pattern 42 formed on the outer surface of the coating layer 38 is shallow, it is difficult to see with the naked eye, and if it is deep, the texture is reduced. Therefore, the average depth is, for example, 0.003 to 0.020 mm. It is preferable that the average pitch of the groove-like recesses 42a having an arcuate top formed between adjacent groove-like recesses 42a is about 0.5 mm. In addition, it is formed over the entire periphery, and forms an appearance in a state where incident light from the outside is irregularly reflected. Such an irregular reflection state is formed over the entire circumference of the peripheral portion of the pattern portion 24 (FIG. 1) by extending the groove-like concave portion 42a or the convex portion 42b along the longitudinal direction. The width on the outer surface of such a groove-like recess 42a is preferably 0.005 to 0.1 mm. This is because if this width is too thin, it is difficult to see with the naked eye, and if it is too thick, the texture will deteriorate. The texture of the pattern portion 24 is a feeling similar to natural bamboo or a feeling that has been completed as an appearance similar to natural bamboo.

  The groove-like recesses 42a that form these linear patterns 42 and the projections 42b that have arcuate tops are formed by forming fine irregularities on the inner periphery of the ironing rubber of a normal ironing coating device, for example. When the coating layer 38 is ironed onto the tubular body 10 through the ironing rubber, it can be formed on the outer surface of the coating layer 38. Such fine irregularities formed on the inner circumference of the ironing rubber may be formed with a molding mold or the like when molding the ironing rubber, or the inner circumference of the finished ironing rubber is diamond reamer, file, etc. It can also be formed by cutting with a tool. In any case, the fine linear pattern 42 formed on the outer surface of the coating layer 38 forms an uneven shape alternately arranged in the circumferential direction on the outer surface of the coating layer 38. If the outer surface of the coating layer 38 is in a state of irregular reflection by the transparent resin, the depth of the concave portion 42a or the height of the convex portion 42b and the pitch thereof are not limited to the above-mentioned sizes, and may not be easily seen with the naked eye. In order not to deteriorate the texture of the appearance, for example, the depth (height) can be appropriately set within a range of 0.003 to 0.020 mm and a pitch of 0.05 to 1.0 mm.

  Inside the coating layer 38, fine particles 44 having a particle size of about 0.3 μm to 15 μm, such as silica, organic beads, calcium phosphate, and calcium carbonate, are mixed as a gloss adjusting material, and the transparent layer forming the coating layer 38 is formed. The gloss or gloss of the resin is suppressed, and the strength of the convex portions 42b forming the fine linear pattern 42 is improved. The transparent resin mixed with such fine particles 44 may be in a cloudy state, and will become frosted after drying. The fine particles 44 may be mixed in the resin forming the coating layer 38 in advance, or may be mixed in the surface portion after the coating layer 38 is formed. In any case, the degree of gloss can be adjusted by adjusting the amount of fine particles 44 mixed in the coating layer 38. Usually, a gloss of 6 to 9 minutes such that the ground color layer 34 and the pattern layer 36 can be visually recognized from the outside (for example, when the outer diameter of the tubular body 12 is about 9 mm and the measurement angle is 85 ° is 40 °). ˜55), it can be arbitrarily adjusted, for example, 8 minutes gloss. Further, by using colored beads or the like, not only the change in gloss but also the change in color due to the groove-shaped recess 42a can be obtained.

  The pattern layer 40 thus formed is a groove formed along the circumferential direction of the fine linear pattern 42 while the coating layer 38 is in a frosted state in which the gloss of the transparent resin is suppressed by the fine particles 44. The concave portions 42a and the convex portions 42b form an appearance in which light is irregularly reflected by the inclined surfaces. As a result, a linear glossy portion along the axial direction, commonly referred to as a highlight line, is not clearly formed on the outer peripheral surface of the coating layer 38 formed of a transparent resin, and a monotonous appearance like a normal coating film In contrast to this, it forms an appearance with a texture and appearance such as that seen on the surface of Japanese bamboo using natural bamboo. Further, the fine line pattern 42 formed on the outer surface of the covering layer 38 reproduces the streak as seen on the surface of natural bamboo.

  It is preferable that the fine particles 44 contain more on the outer surface side of the coating layer 38, that is, on the arcuate top side of the convex portion 42 b than on the side surface portion defining the groove-shaped concave portion 42 a. In particular, it is more preferable to contain more than the side part in the boundary part with the recessed part 42 of the top part side. Moreover, it is preferable to contain more on the both sides or one side than the center part also on the outer surface of the top part side. Moreover, more effective external appearance can be formed when these fine particles 44 protrude from the side part which divides this groove-shaped recessed part 42a. That is, when viewed under a single direction of light (for example, sunlight), if the highlight line and the groove-like recess 42a overlap at the same angle, the light reflectivity changes and It produces a sparkle that makes it look like a paint without light reflecting particles.

  Such a fine linear pattern 42 can be formed not only in a straight line shape along the longitudinal direction but also in a state having a delicate undulation like natural bamboo. In this case, for example, when the coating layer 38 is ironed, the tubular body 10 can be formed by slightly rotating about the longitudinal axis (the rotation of the tip and the base within 360 degrees). it can.

  The step coat portion 26 adjacent to the patterned portion 24 is formed so as to overlap the outermost coating layer 38 of the pattern layer 40. A step is formed on the pattern layer 40 between the front end and the original end of the step coat portion 26 by being formed over the coating layer 38. When forming the step coat portion 26, build up on the coating layer 38 between the front side and the original side end portion of the step coat portion 26, and after curing, perform masking (not shown) to provide a protective layer. As a result, the end portion does not flow into the patterned portion 24 side, the outer surface is smooth, a clear step is formed between the patterned portion 24, and a high-quality appearance can be formed.

  The tubular body 10 formed in this way has a ground pattern 34 and a pattern layer 36 formed on the outer surface of the tubular body 12, and a streak pattern 30 and a spotted pattern 32 that closely resemble natural bamboo. The fine linear pattern 42 formed on the transparent resin coating layer 38 outside the pattern layer 36 is formed on the ground color portion 28 similar to the background color of the bamboo. The texture of the outer appearance of the bamboo can be formed, whereby the appearance can form a more natural bamboo feeling.

  In the above-described embodiment, the tubular body 10 formed for a fishing rod has been described. However, the tubular body 10 is not limited to such a fishing rod, and can be used for a golf shaft, for example.
