  As described above, when the tubular body is formed of FRP, it is made of carbon and is finely knitted (precision) by configuring the surface so that the mesh pattern (pattern in a plain weave state) can be visually recognized on the surface. ) Can be promoted, and consumers' willingness to purchase can be improved. However, in order to make the surface a mesh pattern, it is necessary to wind a prepreg sheet having reinforcing fibers in a plain woven state around the outermost layer (outer layer side) of a mandrel when manufacturing a tubular body according to a conventional method. In such a configuration, the winding state is not stable, and the weight of the tubular body may increase. Moreover, in the above-mentioned Patent Document 1, there is no idea that a decorative layer close to a mesh pattern is formed by painting or printing in a tubular body such as a fishing rod. At the same time, it is difficult to produce a gradation, and it is impossible to produce a precision that can be visually recognized with an actual prepreg sheet.

  The present invention has been made paying attention to the above-described problems, and an object of the present invention is to provide a tubular body having a decorative layer in which a mesh-like pattern similar to the surface appearance by FRP can be visually recognized.

  In order to achieve the above-described object, the tubular body according to the present invention includes a colored layer in which a hue is formed on a tubular body body formed of a fiber reinforced resin material while overlapping a plurality of colorants in a dot shape. The colored layer has a plurality of polygonal regions having different colorant formation densities, and a linear boundary is formed between adjacent polygonal regions. To do.

  In the tubular body having the above-described configuration, a colored layer in which a plurality of polygonal regions are adjacent is formed on the surface. Each adjacent region has a hue formed by overlapping the coloring material in a dot shape, and the adjacent region is in a state where the formation density of the coloring material is different and is separated by a linear boundary. Yes. In this way, gradation is generated by changing the formation density of the colorant that overlaps in the form of dots in adjacent areas, and a decorative layer having a mesh pattern is formed by dividing each area by a linear boundary Is done.

  According to this invention, the tubular body provided with the decoration layer which can visually recognize the mesh-like pattern similar to the surface external appearance by FRP is obtained.

It is a fragmentary perspective view which shows the example of the decoration layer given to the surface of the rod of the fishing rod of FIG. It is a fragmentary sectional view of the collar of FIG. 2 provided with a decoration layer. It is the elements on larger scale of the decoration layer (colored layer) shown in FIG.

  Hereinafter, an embodiment of a tubular body including a decorative layer according to the present invention will be described with reference to the drawings.

  FIG. 1 shows a fishing rod 1 as an example of the tubular body of the present invention. As shown in the figure, this fishing rod 1 includes a plurality of rods as a tubular body, specifically, a main rod 3 having a grip 3a, a first middle rod 5, a second middle rod 7, and a fishing line fastener. It is comprised by the tip 9 which has 9a. In this case, each of the flanges 3, 5, and 7 is configured as a swing-out type or a splicing type, and the tubular body main body (the material body 20; see FIG. 3) constituting each of the flanges 3, 5, and 7 It is formed by winding a fiber reinforced prepreg impregnated with a synthetic resin in a reinforced fiber (may be formed by a metal such as steel), and a decorative portion A is formed on each of the ridges 3, 5 and 7 .

  The decorative part A is formed by ink jet printing as will be described later, and the line pattern A1 and ridge 3 extending linearly over at least a part of the circumferential direction of the ridges 3, 5, and 7 (the entire circumference in the present embodiment). , 5 and 7 extending over at least a part of the circumferential direction (in this embodiment, the entire circumference) and having a plurality of polygonal regions (in this embodiment, a plurality of regions adjacent to each other in a lattice shape) (multiple colors) And A2) and a blurring pattern A3. Here, the blur pattern A3 refers to, for example, a blur portion A3 ′ (for example, linearly extending in the axial direction and having a predetermined width in the circumferential direction) formed of a region where the ink density is thinner than other portions. It is a pattern having an interval, and the density of the blurred portion A3 ′ may change stepwise, for example, along the circumferential direction or the axial direction. Alternatively, the blur portion A3 'may be one in which the composition of the ink color gradually changes.

  The decoration part A (A1, A2, A3) is composed of a decoration layer 25 formed on the material body 20 constituting each of the collars 3, 5, 7 as shown in FIG. Specifically, the decoration layer 25 includes a first base layer (for example, a thickness of 5 to 20 μm) 30 formed on the material body 20 and a second base layer formed on the first base layer 30. A ground layer 31 (for example, a thickness of 5 to 20 μm), a colored layer 32 (for example, a thickness of 10 to 60 μm) formed on the second underlayer 31, and a transparent layer formed on the colored layer 32 It is configured by laminating a protective layer 33 (for example, a thickness of 15 to 25 μm).

  The first underlayer 30 is provided to smooth the outer surface of the material body 20, and is made of, for example, a synthetic resin such as epoxy, urethane, acrylic, acrylic silicon, or silicon, and is sprayed or squeezed. It is formed by various coating methods such as brush coating. The first underlayer 30 may be colored by mixing a pigment or the like.

  The second base layer 31 is intended to adjust the concealment of the base, the brightness and color tone of the colored layer 32, and is composed of a light reflection layer and a white layer. The light reflecting layer is made of a glittering material, for example, a predetermined synthetic resin (acrylic resin, epoxy resin, vinyl resin, etc.) and a plurality of particles having glitter (hereinafter referred to as glitter particles). It can be formed by painting a desired density and uniformly mixed.

  The glitter particles mixed in the predetermined synthetic resin have glitter and various colors such as Al, Cu, Ag, Mg, In, Cr, Si, Ni, Ti, Au, Rh, and Pt. Metal materials can be used. In this case, the size of each particle is set to 2 μm or less, preferably 0.3 μm to 1 μm, and the thickness is set to 1 μm or less, preferably 0.03 μm to 0.5 μm. Good to do. That is, if the size and thickness of the particle body are set outside this range, the glitter particles cannot be uniformly arranged in the synthetic resin at a desired density and the boundaries of the glitter particles become conspicuous. This is because the light reflection direction is not constant, and a uniform glossy appearance cannot be exhibited.

For example, such a glittering particle is formed by depositing or sputtering the metal material on a film-like support substrate made of Teflon (registered trademark), silicon resin, or the like, and then forming the metal layer. It can be formed by peeling the layer from the support substrate and crushing. It is preferable that the plurality of glittering particles formed in this way are uniformly arranged at such a density as to sufficiently exhibit the glitter and produce a desired color. Specifically, the density of the glitter particles mixed in the synthetic resin is preferably set so that the number of glitter particles per unit area is 50,000 to 20 million / mm ² . According to the light reflection layer formed in this way, it is possible to present a glittering appearance that is uniform and colored in a desired color.

  In addition to the configuration described above, the light reflecting layer may be, for example, a single piece of metal such as gold, silver, copper, aluminum, chromium, cobalt, nickel, iron, or zinc, or particles such as pigment, or these. Arbitrary combinations can be formed by mixing this with a small amount of synthetic resin, diluting with a large amount of solvent, spraying this with gun spray coating, etc., and then removing (volatilizing) the solvent. Various appearances can be formed by changing the size and combination of particles such as metal pieces and pigments.

Alternatively, in addition to the configuration described above, the light reflecting layer may be made of metal such as Cr, Ni, Ti, Al, Ag, and Be, alloys such as TiN, TiCN, CrN, and Fe—Cr—Ni, TiO ₂ , SiC, and the like. These ceramics can be formed as a main material, and this can also improve the appearance. Such a light reflection layer using metal or ceramics can be formed using physical plating such as ion plating, sputtering, or vapor deposition, dry plating such as chemical vapor deposition, vacuum vapor deposition, or wet plating. It is. The white layer may be formed by coating a predetermined synthetic resin, but may be formed by inkjet printing. In this case, it is preferable to conceal the base so that the brightness of the colored layer can be easily adjusted.

  The protective layer 33 formed on the colored layer 32 is made of a transparent or translucent synthetic resin such as epoxy, urethane, acrylic, or acrylic silicon.

Next, a specific configuration and forming method of the colored layer 32 formed on the second base layer 31 will be described.
The colored layer 32 has, for example, light transmittance, and includes a plurality of polygonal regions (in this embodiment, a square shape) 40A and 40B, as shown in FIG. 4, and a plurality of these regions 40A and 40B are provided. A hue is formed while overlapping color coloring materials in a dot shape, and dots in each region are printed by an ink jet printer (not shown). The colored layer 32 can be formed, for example, by adding a curing agent to a main material in which a coloring material such as a pigment or a dye is mixed in a transparent or translucent synthetic resin such as epoxy or urethane. However, in this embodiment, an ultraviolet curable ink that is cured by irradiation with ultraviolet rays that are curing light rays is used. Acrylic or epoxy cation type inks are used for the photo-curing type ink. In particular, for the ultraviolet curing type ink, a polyfunctional monomer and an acrylate oligomer mixed with a sensitizer are used. In such an ink, it is utilized that a sensitizer forms a radical and causes a chain reaction of an oligomer and a monomer. The ink may be a thermosetting type, a solvent (water, organic material) drying type, a two-component reaction type, or the like.

  In the printing pattern of the present embodiment, the regions 40A and 40B are configured to be adjacent to each other in a rectangular shape (square shape) having the same size, and the colorant formation density is different in each adjacent region. Controlled droplets are ejected from a printer head (not shown). That is, the printer head forms a cyan, magenta, yellow, and black colorant into droplets via a plurality of ejection nozzles, and controls the material body 20 (second base layer 31) while controlling it. Spray up.

  As shown in FIGS. 2 and 4, the colorant ejected to each of the regions 40 </ b> A and 40 </ b> B is ejected and controlled so that the formation density of the colorant differs between adjacent portions. The amount is large (the formation density is large and the concealment property is large), and in the adjacent region 40B, the amount of ejected dots is smaller (the formation density is small and the concealment property is small). In other words, the colored layer 32 is in a state where regions 40A with a large amount of ejected dots and regions 40B with a small amount of ejected dots are alternately arranged, and are separated by boundaries, which will be described later. A mesh pattern is formed.

  In addition, the dots formed as described above can be controlled to be ejected while being superimposed each time the printer head is reciprocated along the scanning direction (for example, the axial direction X of ridges 3, 5, and 7). Therefore, it is possible to increase the thickness in the region 40A and reduce the thickness in the region 40B to make the surface uneven (change the height in the adjacent region). Thus, a three-dimensional appearance and an appearance that senses a sense of surface irregularity can be achieved.

  In the present embodiment, the polygonal regions 40A and 40B described above are all formed in a rectangular shape having the same size (a square shape with one side of about 0.5 to 10 mm), and the colored layer 32 is In addition, a plurality of linear boundaries 41 and 42 are provided between adjacent regions. That is, the boundaries 41 and 42 are formed substantially in parallel and intersect the orthogonal direction to divide the regions 40A and 40B, whereby a plurality of polygonal regions (square regions 40A, 40B), a lattice pattern is formed.

  According to the colored layer 32 configured as described above, a mesh pattern can be expressed by the adjacent polygonal regions 40A and 40B. In this case, each of the regions 40A and 40B is formed in the same square shape and has a lattice shape, and the boundaries 41 and 42 are all substantially parallel to each other and intersect with each other in a straight line. A feeling of precision like a reinforced fiber can be expressed. Further, since the adjacent regions 40A and 40B have different hues due to the colorant superimposed in a dot shape, that is, the ratio (density) of the colorant, a natural gradation can be produced and a three-dimensional effect can be obtained. .

  Furthermore, for the appearance such as knitted reinforcing fibers as described above, when trying to form by screen printing, alignment and the like is extremely difficult, and tends to be a planar appearance, but by using inkjet printing, It is possible to easily form the appearance of a knitted pattern having a three-dimensional feeling between the respective regions.

In the colored layer 32A of this configuration example, a plurality of polygonal regions include four rectangular shapes having different sizes (each indicated by reference numerals 50A to 50D), and these are combined in a predetermined pattern to form a colored layer. Has been. That is, the region 50A is a region having a substantially square shape and a large dot amount formation density, the region 50B is a rectangular shape and a small dot amount formation density, and the regions 50C and 50D are rectangular and have dots added thereto. The underlying layer 31 is a region that can be seen as it is, and these are repeatedly arranged adjacent to each other.

  Further, between each adjacent region, a plurality of linear boundaries 51A, 51B, 51C (X direction which is the axial direction of the ridge) and a plurality of linear boundaries 52A, 52B, 52C (Y direction perpendicular to the axial direction of the ridge).

  As described above, a plurality of rectangular regions are regularly combined, and the density of the coloring material in each region is also regularized, and the boundaries 51A, 51B, 51C directed in parallel directions, and By dividing the boundary with the boundaries 52A, 52B, and 52C that are directed in a direction orthogonal to and parallel to them, it is possible to express a net-like pattern as a whole. In particular, by forming an area where dots are not added (area where the density of the colorant is zero), this area becomes an accent (monochrome system of the underlying layer), and the other area is highlighted to create a three-dimensional pattern. It becomes possible to make it visually visible.

FIG. 6 is a partial enlarged view showing a third configuration example of the colored layer.
The colored layer 32B of this configuration example includes a rectangular first region 60A and a rectangular second region 60B arranged adjacent to each other, and a coloring material is overlapped in a dot shape in these regions. A plurality of rectangular regions 60a1 (60b1) and a plurality of regions 60a2 (60b2) to which dots are not provided are alternately arranged adjacent to each other.

  In this case, the rectangular regions 60a1 and 60b1 in which the coloring materials are overlapped in a dot shape gradually change in density linearly along the axial direction (X direction and Y direction) (the density gradually changes along the axial direction). ), And all of them are formed so as to change the shading unified in the axial direction. In addition, the rectangular regions 60a1 and 60a2 and the rectangular regions 60b1 and 60b2 are divided by a large number of adjacent linear boundaries 61 and linear boundaries 62 orthogonal to these, thereby forming a mesh. A visible pattern is formed as a shape.

  As described above, by regularly combining a plurality of rectangular regions and arranging regularly the portions that change linearly in light and shade, it is possible to express a pattern that looks like a net as a whole, and in addition, the fiber structure It is possible to express the pattern.

FIG. 7 is a partially enlarged view showing a fourth configuration example of the colored layer.
The colored layer 32C of this configuration example regularly arranges the regions 70A and 70B to which dots are imparted in a rectangular shape (rectangular shape) in the X direction and the Y direction, and a rectangle in which no dots are imparted therebetween. Shaped (square) regions 70C are arranged. In addition, a large number of boundaries 71 and boundaries 72 that divide each of the areas 70A, 70B, and 70C are formed substantially in parallel, intersect in orthogonal directions (X direction, Y direction), and are rectangular areas. 70A and 70B are formed so as to express a state of being folded into a fiber shape (biaxial woven pattern).

  According to the configuration described above, as the adjacent polygonal regions, a rectangular region to which dots are added and a blank square region to which dots are not provided are provided and arranged in parallel to partition the regions. By forming the boundaries so as to overlap each other in the crossing direction, it is possible to easily form a patterned layer in which the reinforcing fibers are knitted so as to intersect two axes (two axes perpendicular to each other).

FIG. 8 is a partially enlarged view showing a fifth configuration example of the colored layer.
The colored layer 32D of this configuration example regularly arranges the regions 80A, 80, and 80C to which dots are added in a rectangular shape (parallelogram shape) so as to intersect at a predetermined angle, and between them, the dots The hexagonal regions 80D that do not provide the are arranged. In addition, a large number of boundaries 81, 82, and 83 that partition these regions 80A to 80D are formed substantially in parallel, and intersect each other at a predetermined angle so that the regions 80A, 80, and 80C are folded into a fibrous shape. It is formed so as to express the state (triaxial weave pattern).

  According to the configuration described above, as a polygonal area adjacent to each other, a parallelogram-shaped area to which dots are added and a blank hexagonal area to which dots are not provided are provided and arranged in parallel to partition the areas. By forming the boundaries so as to overlap in a direction intersecting at a predetermined angle, it is possible to easily form a patterned layer knitted so that the reinforcing fibers intersect with each other in three axes.

FIG. 9 is a partially enlarged view showing a sixth configuration example of the colored layer.
The colored layer 32E of this configuration example includes a rectangular area 90A with dots, a parallelogram area with dots 90B, a five-stroke area with dots 90C, and a hexagonal area with dots 90D. Are regularly arranged so as to cross each other at a predetermined angle, and triangular regions 90E to which dots are not provided are arranged therebetween. In addition, a large number of boundaries 91, 92, 93, and 94 that divide these regions 90A to 90E are formed substantially parallel to each other, and intersect each other at a predetermined angle so that the regions 90A to 90D are folded into a fiber shape. It is formed so as to express the state (4-axis woven pattern).

  As described above, the polygonal regions adjacent to each other are variously deformed, and the parallel arranged boundaries separating the regions are formed so as to overlap each other in a direction intersecting at a predetermined angle. It becomes possible to easily form a patterned layer knitted so that the fibers intersect in four axes.
