DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, specific embodiments will be described with reference to the accompanying drawings.
FIG. 1 is a cross-sectional view of a tubular body showing a first embodiment. In the figure, reference numeral 1 denotes a material of the tubular body main body. A base layer 2 is provided on the material 1, and a seal-like member 3 having glitter such as a hologram is provided on a part of the base layer 2. In this case, the seal-like member 3 may be cut so as to form a pattern as a whole, or may be cut so as to express characters and figures. Moreover, you may form the level | step difference filling layer of the sealing member 3 with urethane type resin, an epoxy resin, etc. FIG. A metal film 5 is coated on the base layer 2 and the seal-like member 3 by the above-described means, and a transparent or translucent protective layer 7 is formed thereon.
[0012]
In this configuration, the metal coating 5 is preferably formed so thin that the underlayer 2 and the seal-like member 3 appear as appearance, and specifically, it is preferably formed to have a thickness of about 1 nm to 1 μm. Moreover, as the said base layer 2, decoration layers, such as a coating layer and a printing layer, a double molding layer, etc. can be used. In this case, the surface of the base layer 2 may be uneven so that the direction of light reflection in the metal coating 5 formed on the base layer 2 is concentrated in a specific direction. Since the underlayer 2 may be provided as necessary, the surface of the material 1 may be formed in an uneven shape when the underlayer 2 is not provided. Moreover, as a material of the said protective layer 7, a fluororesin coating material, an epoxy resin coating material, etc. can be used. The thickness is preferably 5 to 100 μm in consideration of adhesion, water resistance, wear resistance and the like. In addition, the base layer 2 and the protective layer 7 can be formed by ordinary squeeze coating, gun spray coating, step coating (brush coating), or the like.
[0013]
In the above-described configuration, the metal coating 5 is thin enough to represent the color of the underlayer 2 or the material 1 as an appearance, so that the color of the underlayer or the material can be sufficiently visually recognized and the light reflection effect by the metal coating 5 is reduced. Add to the color of the formation or material. Therefore, the appearance is excellent with gloss added to the color of the underlayer or material.
[0014]
And in the part which provided the seal-like member 3, since the color with its own glitter is added, this can be visually recognized separately from the base layer 2 or the raw material 1. FIG. In this case, as described above, the metal coating 5 is coated from above the seal-like member 3 and is not concealed by the seal-like member 3, so that the glitter by the metal coating 5 is discontinuous. It does not change and the overall appearance is not inferior.
[0015]
In the above configuration, the metal coating 5 may be formed as follows. That is, the metal film 5 is coated to a thickness of about 5 nm to 3 μm in consideration of the leveling effect and the like. Specifically, the thickness of the metal film 5 is a value obtained by dividing an odd multiple of a quarter optical film thickness of the color wavelength desired to be obtained as an appearance by a refractive index, that is, (2m + 1) · λ / 4 = nd (λ : Wavelength, n: refractive index, d: film thickness, m: integer) can be set so as to satisfy a single color. As a result, the interference effect is strengthened and the color development becomes vivid. For example, the thickness of the metal coating 5 is preferably an odd multiple of 107.5 to 122.5 nm where nd is λ / 4 when a blue color having a wavelength of 430 to 490 nm is developed, and a wavelength of 490 to 550 nm. Is preferably an odd multiple of 122.5 to 137.5 nm where nd is λ / 4, and when nd is colored (yellow) with a wavelength of 550 to 590 nm, nd is It is preferably an odd multiple of 137.5 to 147.5 nm, which is λ / 4, and when coloring red light having a wavelength of about 640 to 780 nm, it is an odd multiple of 160 to 195 nm where nd is λ / 4. It is preferable.
[0016]
In addition, since the metal film 5 should just reflect light, a color is arbitrary and may be a single layer and may be a multiple layer. In this case, a metal film that does not exhibit a single color and a metal film that exhibits a single color may be provided in combination. In this way, by partially utilizing the light reflection by the metal coating 5 and expressing the appearance, it is possible to express a tasteful appearance as a whole.
[0017]
Next, another embodiment of the present invention will be described. In the following embodiment, the same reference numerals are given to the same components as those in the above embodiment, and the description thereof is omitted or simplified.
[0018]
FIG. 2 is a cross-sectional view of a tubular body showing a second embodiment. In this embodiment, a brilliant seal-like member or a synthetic resin film 13 is wound or disposed on the material 1 with a predetermined interval through the base layer 2. With such a configuration, it is possible to form a concavo-convex shape on the metal film 5 coated thereon, and in addition to the effects obtained in the above-described embodiment, it represents an unusual appearance in which the concavo-convex shape can be visually recognized. It becomes possible. The uneven shape can be variously changed by changing the size, arrangement interval, etc. of the seal-like member or the synthetic resin film. In addition to the seal-like member and the film, for example, a fishing line guide in a fishing rod is fixed. It can also be formed by yarn.
[0019]
FIG. 3 is a cross-sectional view of a tubular body showing a third embodiment. It is also possible to configure the portion where the above-described seal-like members 3 and 13 are provided so as to exhibit a lens effect. In this embodiment, the lens effect is exhibited with respect to the configuration shown in FIG. 1, and a transparent member such as an epoxy resin or a urethane resin is formed on the seal-like member 3. 10 is formed and then the metal film 5 is coated.
[0020]
By comprising in this way, the pattern of the seal-like member 3, a color, etc. can be expanded and the outstanding external appearance can be obtained. Such a lens effect can also be obtained by curving the surface of the protective layer 7 on the seal-like member 3 into a concave shape or a convex shape. Of course, in this configuration as well, the metal coating 5 is coated from above the seal-like member 3, so that the glitter due to the metal coating 5 does not change discontinuously and the overall appearance is inferior. There is nothing.
[0021]
FIG. 4 is a cross-sectional view of a tubular body showing a fourth embodiment. The seal-like members 3 and 13 as described above may be formed by forming fine uneven portions on the surface. The seal-like member 3a of this embodiment is obtained by forming an uneven portion on the surface of the seal-like member shown in FIG. By configuring the seal-like member in this way, incident light can be diffusely reflected, and the glitter of the metal coating 5 on the seal-like member 3a can be lowered, thereby expressing a strange appearance. Is possible.
[0022]
As described above, as means for reducing the glitter of the metal coating 5, for example, a seal-like member coated with, for example, epoxy resin, urethane resin ink or matte paint is provided on the material 1, or the base layer 2 is provided. It can also be realized by directly printing the ink or applying a matte paint, or by polishing the surface of the material 1 or the underlayer 2.
[0023]
FIG. 5 is a cross-sectional view of a tubular body showing a fifth embodiment. In this embodiment, a joint portion of a fishing rod of a fishing rod is shown. A base is attached to an end portion which is a joining portion of the soot tube, and this base is usually attached from above a metal film which is physically vapor-deposited. For this reason, the glitter due to the uniformly coated metal film changes discontinuously at the base portion, and the overall appearance is poor.
[0024]
On the other hand, in the present embodiment, the metal coating 5 is physically vapor-deposited after the base 15 is attached to the material 1 which is a soot tube. Thus, by physically vapor-depositing the metal film 5 on the base 15 and the material 1, the above-described glitter due to the metal film is prevented from changing discontinuously at the base part, and the appearance as a whole Is no longer inferior.
[0025]
Alternatively, as shown in the sixth embodiment in FIG. 6, a glossy seal-like member 20 that exhibits a metallic color may be provided at a location where the base is disposed without actually mounting the base. . Such a seal-like member 20 can give the impression that the metal part of the base is attached to the portion in appearance. Or you may vapor-deposit a metal so that the thickness of a metal film may differ in the location where a nozzle | cap | die is arrange | positioned. According to such a configuration, since no metal part is actually mounted, no step is generated and the weight is not increased.
[0026]
FIG. 7 is a plan view of a tubular body showing a seventh embodiment. As described above, the metal coating formed by physical vapor deposition is uniformly formed on the article such as the material of the tubular body (underlayer) and the seal-like member (film-like member). This prevents the glitter due to the metal coating from changing discontinuously. In this case, as shown in FIG. 7, the seal-like members 23a to 23d provided on the material 1 (underlying layer 2) of the tubular body main body are wound stepwise in the axial direction with a difference in color, brightness, and the like. Thereafter, if a metal film is formed, a corrugated pattern in which the glitter does not change discontinuously can be formed. Further, when forming this corrugated pattern, a rough surface may be formed on each seal-like member, in addition to providing the seal-like member with the difference in color and brightness as described above. Alternatively, metal may be vapor deposited so that the thickness (color tone wavelength) varies stepwise, thereby forming a corrugated pattern.
[0027]
FIG. 8 is a view showing an eighth embodiment, and is a view showing an embodiment in which the present invention is applied to a fishing rod as a tubular body, in particular, a reel seat portion provided at a base end portion. (A) is a figure which shows the base end part of a fishing rod, (b) is the longitudinal cross-sectional view.
[0028]
Hereinafter, the manufacturing process of this fishing rod will be described. First, the reel sheet 31 is fixed to the soot tube 30 produced by a normal molding process. In this reel sheet 31, a fixed hood 31a for actually locking one side of the reel leg 50 and a moving hood 35 for locking the other side of the reel leg 50 are moved in the axial direction. The male screw portion 31b is formed. Then, the soot tube 30 to which the reel sheet 31 is fixed in this manner is put in a vacuum vessel, and a metal film is formed on the entire surface by physical vapor deposition or the like.
[0029]
Thus, batch production is possible by forming the metal coating on the surface of the tubular body (sheath tube) and the surface of the component (reel sheet) at once, and the manufacturing cost can be reduced. Further, in this case, since the metal coating is integrally formed as a whole with the component attached, the appearance can be improved without causing a sense of discomfort between the components and the tubular body.
[0030]
In addition, when attaching components, such as a reel sheet, to a tubular body main body, a level | step difference may arise between tubular body main bodies. For this reason, if the build-up part 40 is formed with a paint, a synthetic resin, or the like before the physical vapor deposition step on such a stepped portion and polished so as to be flush with the step portion, It is possible to finish the entire surface to a smooth surface.
[0031]
In addition to the reel sheet described above, for example, a plurality of tubular bodies (soot tubes) may be fitted and a metal coating may be formed on the fitting portion. By doing in this way, an external appearance can be improved, without the discomfort of brightness between the pipes connected together.
[0032]
Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be variously modified. For example, it is possible to combine the configurations of the above-described embodiments as appropriate.
[0033]
【The invention's effect】
As described above, according to the present invention, when a part is attached to a tubular body having a metal coating, after such a part is attached, the metal coating is integrally formed. The appearance can be improved by preventing discontinuous changes in brightness and discomfort in glitter. As for the appearance of this tubular body, the color of the tubular body main body and the part is glossed by a metal coating, and the color of the part itself is visually distinguished from the other parts of the tubular body main body in the part provided with the part. Therefore, the appearance of the tubular body can be improved.
