DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rod constituting a fishing rod.

[0002]

2. Description of the Related Art In a conventional fishing rod, the surface is colored with paints of various hues, a pattern is formed to improve the appearance, and the surface is protected. The paint used for this coating is urethane. A pigment such as a pigment is mixed into a base of a paint such as a resin or an acrylic resin to be colored to a desired hue, and applied to the outer surface of the fishing rod by means of sword painting, spray painting using a spray gun, or the like. In addition, the rubbing coating is performed by supplying a coating material to an opening formed in a flexible material such as rubber while inserting the tubular body in a state of being in contact with the inner surface of the opening (scratching state). This is a coating method in which a paint is applied to the surface.

[0003]

Here, assuming that the tubular body is to be coated to obtain a desired hue appearance, the coating is applied with an appropriate thickness when the coating is performed. In addition, in order to form a desired hue pattern or the like on a specific portion of the surface, the paint is often applied only on the specific portion.

Further, in order to enhance the decorativeness of a fishing rod, it is often necessary to paint a specific portion with various hues (to perform multicolor coloring), but such a large number of hues are required. In order to achieve this, it is necessary to form the coatings of the respective hues with an appropriate thickness, which makes it difficult to apply them.

In other words, when a specific portion of the surface of the tubular body is colored, a step of arranging a mask before painting is required.
Since a proper thickness is required for the coating film, it takes a long time to dry, and in the case of applying the paint in this manner, the more the color is multicolored, the thicker the coating film becomes and the thicker the tubular body becomes. Since the weight increases and the colored portion becomes a raised shape and the touch becomes worse, improvement is desired.

An object of the present invention is to form a tubular body having a small weight increase due to a film for coloring and having a good surface feel.

[0007]

A feature of the present invention according to claim 1 is that a sheet-like prepreg, in which high-strength fiber is impregnated with a thermosetting resin, is wound around a core material and fired to form a tube. A coating film is formed on the outer surface of the tubular body formed at the same time, an interference thin film is formed on the outer surface of the coating film by vacuum deposition, and the light reflected on the surface of the interference thin film and the light reflected on the boundary surface on the coating film side. The light beam having a specific wavelength is caused to disappear by causing interference with the light beam to form a complementary color, and the thickness of the interference thin film is formed to be nonuniform in the axial direction of the tubular body. According to a second feature of the present invention, the outer surface of the coating film is formed as a smooth surface, and in the third feature of the present invention, the outer surface of the coating film is formed in a gently wavy shape. The operation and effect are as follows.

[0008]

According to the first aspect of the present invention, since the interference thin film is formed by vacuum evaporation, the film thickness can be made extremely small (the film thickness is usually 7000 ° or less), and light rays are projected on the surface of the interference thin film. In this case, the light beam reflected on the surface of the interference thin film and the light beam reflected on the boundary surface of the interference thin film on the coating film side interfere with each other, and a light beam of a predetermined wavelength is extinguished (quenched). The reflected light having a hue that is a complementary color of the wavelength obtained is obtained (color is developed). Also, since an interference thin film is formed on the outer surface of the coating film formed on the tubular body,
Even if the surface of the tubular body is a rough surface, a reflected light beam having the outer surface of the coating film as the boundary surface is obtained, and irregular color reflection is suppressed, and color development with high luminance is achieved. Since the thickness of the interference thin film is formed to be non-uniform in the axial direction of the tubular body, the wavelength of the light beam that disappears in an adjacent portion in the axial direction of the tubular body differs due to the difference in the film thickness. In this case, different colors occur in different portions, and multicolor coloring is possible.

That is, according to the present invention, since the interference thin film is formed in an extremely thin film, the weight of the interference thin film is hardly increased and the swelling is not felt in the thin film forming portion. At least, it develops under the condition that light rays enter. Moreover, even if the surface of the tubular body has a surface such as a high-strength fiber and the surface is rough, the exposed high-strength fiber and the like can be covered with the coating film by applying a coating film on the surface, and the vacuum It is possible to form an interference thin film having a small variation in the vapor deposition density of the vapor-deposited substance with respect to the surface of the coating film, and to obtain a color with high luminance by a simple process of forming the coating film. Incidentally, when the yellow-green light is extinguished (quenched) due to interference of the white light, a complementary color of yellow-green, that is, purple reflected light is obtained.

[0010] In addition to the above-described operation, there is an operation by applying the interference thin film to the rod body. [1] Even in a static state, it was described that a multi-colored state due to the non-uniformity of the film thickness in the axial direction of the tubular body could be recognized. In the meantime, when the tip of the tip recurs in the vertical direction in response to the up and down of the wave and the tip rod bends in an arc shape, or when the entire fishing rod is bent when throwing the device by swinging the rod, The angle of an incident light beam continuously changes in each part of the rod even in a dynamic state such as when the rod forms an arc-shaped bend when catching a fish.
Therefore, a multicolored state corresponding to the curvature of the arc-shaped bent tip rod or the like is seen, and the multicolored state changes in accordance with the change in the curvature, and not only the person who operates the rod but also , And will be noticeable to nearby anglers. Then, by paying attention to the point at which the multicolored state changes, it is possible to catch the hit as a fish, which makes it easier to catch the hit and has a good effect on the fishing results. [2] Since the rod body is cylindrical and its outer shape is circular, the angle of incident light differs for each part along the circumferential direction of the outer surface of the rod body even if sunlight shines from a certain direction. However, since the effective film thickness in the direction along the incident light beam will change, multicolor coloring will be seen along the circumferential direction,
The visibility is improved. In particular, it will attract the attention of nearby anglers who will see the pole from the side. [3] When fishing with a pole, it is possible to avoid an unexpected situation such as accidentally stepping on the rod due to a high visibility.

Since the vacuum deposition method is used to form the interference thin film, there is no difference between the rods as a product for each production rod, the product can be homogenized, and the coating film needs to be multilayered. Because there is no, the desired decoration state can be obtained in one stroke, and the rod can be significantly reduced in weight. In particular, there is a high demand for a lightweight rod for long use (extended to the zoom state) for use. It can be a rod with no weight.

The phrase "the outer surface of the coating film is smooth" described in the invention according to the second aspect is used to mean that the surface is not in a shape of gently waving, that is, there is no uneven surface.

The invention according to claim 2 and the invention according to claim 3 are based on the invention according to claim 1, and are shown as a form in which the film thickness is formed non-uniformly. The outer surface of the coating film is formed into a smooth surface to make the film thickness non-uniform, and in claim 3, the outer surface of the coating film is made gently wavy to make the film thickness non-uniform. Here, considering the optical effect of the case where the outer surface of the coating film is a smooth surface and the case where the outer surface of the coating film is gently wavy, when the wave is large, it is locally smooth. Can be considered as
Light behaves similarly to a smooth surface. Therefore, claim 3
Since the invention according to the present invention has a shape that gently undulates, it can be considered as having a shape similar to a smooth surface, and light rays incident at the same incident angle correspond to changes in film thickness that change in the axial direction of the rod. Then, the light interferes with the light beam reflected on the surface of the interference thin film, and has a multicolored color. From the above, in the case of claim 2 and claim 3, an interference color corresponding to a change in film thickness is exhibited.

As described above, the color development in a static state has been described. However, when the rod is bent to change the incident angle of light, the interference color changes regularly according to the curvature. Happens.

[0015]

As described above, various colored states can be seen over the entire length of the rod, and the rod bends during the fishing operation, so that the colored state changes according to the change in the bend and the visibility is high. When throwing a device by shaking the rod, the bending of the rod changes subtly, and the multicolored state changes from the beginning of the throw to the end of the throw, attracting the eyes of nearby anglers Thus, it is possible to obtain a highly visible product. Even if partial decoration is applied, there is no swelling and the surface of the interference thin film has a good feel, often holding for a long time at the grip part of the original rod, or sometimes holding the hand on the intermediate rod, The fishing operation can be made lighter and easier with the lighter rod.

Further, in the present invention, it is possible to form a multi-colored color by simply adjusting the film thickness without performing the application of a plurality of kinds of paints as in the prior art, and it is possible to form the interference film by a simple operation. And a uniform interference thin film can be obtained in a short time.

[0017]

1A and 1B show a rod used for a fishing rod. The rod shown in FIG. 1A has an interference thin film A formed on the entire surface thereof, and the rod shown in FIG. The body is partially interference thin film A
Are formed, and each is configured to obtain a multicolored color at the portion of the interference thin film A.

That is, the tubular body 1 is obtained by winding a sheet-shaped prepreg, in which high-strength fibers such as carbon fibers and glass fibers are impregnated with a thermosetting resin such as an epoxy resin, around a core material and firing the same. It is formed into a tubular shape (manufacturing process is not shown), and a single-layer or multi-layer coating film 2 is formed on the outer surface of the tubular body 1 by means of sword coating, spray coating or the like. The outer surface S of the film 2 is finished smoothly. The coating film 2 uses the same technology as the conventional coating technology, and the outer surface S is smoothly finished by clear coating or the like.

As shown in FIG. 3, the tubular body 1 coated with the coating film 2 is placed in a vacuum vessel 6, and the evaporation material is evaporated from an evaporation source 7 by means such as resistance heating to form the coating film 2 of the tubular body 1. The coating film 2 is deposited on the surface by means of so-called vacuum deposition.
The interference thin film A is formed on the surface of the substrate. Also, during this deposition,
A monitor plate or the like may be arranged inside the vacuum vessel 6 and the thickness may be measured from the outside of the vessel while controlling to obtain a desired film thickness. It is also possible to arrange such that the film thickness is formed non-uniformly by disposing 8.

In order to obtain a desired film thickness, a monochromatic photometric method is used.
It is also possible to obtain a film thickness with high accuracy by using means such as a two-wavelength photometric method and a wavelength scanning method. The deposition material may be a metal such as aluminum (Al) or gold (Au) in addition to an oxide used for coating optical glass, such as magnesium fluoride (MgF ₂ ) and titanium oxide (TiO ₂ ). .

The interference of light rays is represented by a physical formula, nd = (2m + 1) λ / 4, where (n: refractive index of thin film, d: thickness of thin film, m: integer, λ:
(Wavelength of light beam) A light beam having a wavelength satisfying this equation is extinguished (quenched). In this formula, interference occurs even if the film thickness is 1/4 of the wavelength of the light beam or a film thickness which is an integral multiple of 1/2 of the wavelength to the film thickness of 1/4 of the wavelength of the light beam. (Even if the film satisfies this condition, the thickness of 10 μm or more causes poor interference). When the yellow-green light is extinguished (quenched) by the interference of the white light, the complementary color of yellow-green, that is, the violet reflected light Is obtained.

In the case where the interference thin film A is formed as described above, as shown in FIG.
1 and the boundary surface on the rod side of the interference thin film A (the outer surface S of the coating film 2).
As a result of the interference with the light ray R2 reflected by the portion (a), a specific wavelength disappears in accordance with the thickness d of the portion and the refractive index of the interference thin film A, and the color is formed.
As shown in the figure, since the film thickness d is non-uniform so as to change in a wavy manner, almost all hues in the visible region can be obtained in the interference thin film A, and the interference thin film A In the case where the interference thin film A is formed on the entire surface of the rod body or partially on the outer surface of the tubular body 1, a multicolor (rainbow) appearance is obtained at the portion, and extremely good decorativeness is provided. Will do.

[Other Embodiments] The present invention is configured as follows in addition to the above embodiment. (A) As shown in FIG. 4, a coating film 2 whose outer surface is not smooth (a coating film 2 whose surface is gently wavy) is formed on the surface of the tubular body 1. An interference thin film A having a smooth surface is formed on the outer surface S. By forming the interference thin film A in this manner, the thickness of the interference thin film A becomes non-uniform, and a multicolored color is obtained.

(B) As shown in FIG. 5, on the surface of the tubular body 1, a coating film 2 whose outer surface is not smooth (a coating film 2 whose surface gently undulates) is formed. An interference thin film A is formed on the outer surface S of the film 2 so that the surface becomes an outer surface that is not even smoother (wavy outer surface). By forming the interference thin film A in this manner, the thickness of the interference thin film A becomes non-uniform, and a multicolored color can be obtained even locally.

As shown in FIG. 6, a coating film 2 having a non-smooth outer surface (a coating film 2 whose surface is gently wavy) is formed on the surface of the tubular body 1. When the interference thin film A having a substantially constant film thickness is formed on the outer surface S of the rod 2, the color of the surface of the rod becomes a fixed hue as a whole, but the color is formed depending on the direction in which the rod is viewed. Changes slightly.
