  Hereinafter, the case where the surface structure according to various embodiments is applied to a fishing rod which is one of industrial products will be described. However, the surface structure according to these embodiments may be applied to any industry including fishing tackle, golf equipment, and the like. Applicable to products.

  FIG. 1 is an enlarged cross-sectional view showing a configuration of a certain part of a fishing rod provided with a surface structure according to an embodiment of the present invention. The surface structure 10 according to the present embodiment includes a substrate 20 made of fiber reinforced plastic, a coating layer 30 disposed on the substrate 20, and a resin layer disposed on the coating layer 30. 40.

The base material (fishing rod main body) 20 is formed of a fiber reinforced prepreg sheet obtained by impregnating reinforcing fibers (carbon fibers, glass fibers, etc.) with a synthetic resin. The base material 20 includes a resin and a plurality of fibers (carbon fibers, glass fibers, etc.) 22. FIG. 1 shows a state in which the fibers 22 extend in the depth direction on the paper surface.
In FIG. 1, only the fibers 22 extending along the circumferential direction of the substrate 20 are shown in the substrate 20, but the fibers 22 extending in the axial direction of the substrate 20 are shown in the substrate 20. Or the fiber 22 extended in arbitrary directions may be contained.
The coating layer 30 is formed by spraying a paint by, for example, ink jet printing. The coating layer 30 has a plurality of through holes (not shown) as will be described later.
The resin layer 40 has a saw-like cross-sectional shape that matches the shape of the molding tape used during firing. The resin forming the resin layer 40 is a resin that has flowed out of the substrate 20 through a through hole (not shown) of the coating layer 30.

  In the example shown in FIG. 1, as the resin contained in the base material 20 flows out through a through hole (not shown) of the coating layer 30, the fibers 22 contained in the base material 20 are in this region. It enters and is in close contact with the coating layer 30.

Moreover, in the example shown in FIG. 1, since the unevenness | corrugation of a shaping | molding tape is absorbed by the resin layer 40 which flowed out from the base material 20 instead of the coating film layer 30, the coating film layer 30 can be formed thinly. Thereby, weight reduction of a surface structure, ie, a fishing rod, can be achieved.
Furthermore, since the resin layer 40 covers the coating layer 30, the situation where the coating layer 30 is worn and discolored can be suppressed.

A fishing rod provided with such a surface structure is produced, for example, by the following procedure.
First, a flat fiber reinforced prepreg sheet (fiber reinforced plastic sheet) is prepared. The fiber reinforced prepreg sheet is formed by impregnating a reinforced fiber (carbon fiber, glass fiber or the like) with a synthetic resin.

  Next, a paint is applied to the surface of the flat fiber-reinforced prepreg sheet by ink-jet coating printing. For example, cyan, magenta, yellow, and black inks (here, UV curable paint) are sprayed onto the surface of the fiber-reinforced prepreg sheet after adjusting the amount of each ink. Thereby, the coating layer 30 mentioned above is formed.

Furthermore, the coating material provided on the surface of the fiber reinforced prepreg sheet is cured (UV cured) by being irradiated with ultraviolet rays.
Thereafter, the fiber-reinforced prepreg sheet is wound around a mandrel. Since the paint applied to the fiber-reinforced prepreg sheet has already been cured by UV curing, the coating layer 30 has a core metal extending direction (that is, a fishing rod) as the fiber-reinforced prepreg sheet is bent. And the through-holes (cracks) extending along the direction perpendicular to the extending direction of the cored bar and the through-holes (cracks) are formed.

Next, a molded sheet is spirally wound around the fiber-reinforced prepreg sheet. In this state, the fiber reinforced prepreg sheet is fired. During this firing treatment, the resin contained in the base material 20 reaches the top of the coating layer 30 through the through-holes (cracks) formed in the coating layer 30, and the top of the coating layer 30 The resin layer 40 disposed on the substrate is formed. As shown in FIG. 1, the resin layer 40 has a saw-shaped cross section that matches the shape of a spirally wound molded sheet.
Then, the fishing rod 10 provided with the surface structure according to the present embodiment is formed by extracting the cored bar.

FIG. 2 is an enlarged cross-sectional view showing a configuration of another portion of a fishing rod provided with a surface structure according to an embodiment of the present invention. As shown in FIG. 2, the coating layer 30 has a through hole 32 (that is, a portion where no coating exists). The resin present in the base material 20 flows out of the base material 20 through the through holes 32 in accordance with the baking treatment, and forms the resin layer 40 that covers the coating layer 30.
Since the resin layer 40 covers the coating film layer 30, the resin layer 40 functions to suppress peeling of the coating film layer 30.

A resin continuously connected to the resin constituting the resin layer 40 may be disposed in (at least a part of) the through-hole 32. Thereby, since the resin layer 40 has the convex resin extending into the through hole 32, it becomes difficult to peel from the coating film layer 30 by using the convex resin as an anchor. FIG. 2 shows, as an example, a state in which the inside of the through hole 32 is filled with a resin that is continuously connected to the resin that forms the resin layer 40.
Further, the resin extending into the through hole 32 may be continuously connected to the resin contained in the base material 20. Thereby, since resin continuously extended in the resin layer 40, the through-hole 32, and the base material 20 exists, peeling of the resin layer 40 and the coating-film layer 30 is suppressed more reliably.

  FIG. 3 is an enlarged cross-sectional view showing a configuration of still another portion of a fishing rod provided with a surface structure according to an embodiment of the present invention. As shown in FIG. 3, the coating layer 30 has a recess 34 on its lower surface. FIG. 3 shows a large concave portion 34 a and a small concave portion 34 b as examples of the concave portion 34. The fibers 22 contained in the base material 20 have entered (arranged) the recess 34a so as to fill the recess. In other words, the coating layer 30 is disposed (invades) in the concave portion (the concave portion surrounded by the fibers) formed in the base material 20 so as to fill the concave portion. In addition, as shown in FIG. 4, a part of one of the fibers 22 included in the base material 20 is accommodated in the recess 34 b.

  In the example shown in FIG. 3, a concave portion (convex portion) is formed on the surface where the coating layer 30 is in contact with the base material 20, and a convex portion (concave portion) is formed on the surface where the base material 20 is in contact with the coating layer 30, The coating film layer 30 and the base material 20 are physically coupled by the engagement of the concave portion (convex portion) of the coating layer 30 and the convex portion (concave portion) of the base material 20. Thereby, the adhesiveness between the coating-film layer 30 and the base material 20 can be improved.

  FIG. 5 is a top view showing a configuration of still another portion of a fishing rod provided with a surface structure according to an embodiment of the present invention. 6 is a partially enlarged perspective view showing the structure of the fishing rod shown in FIG. 5 and 6, the representation of the resin layer 40 is omitted for convenience. 5 and 6, unlike FIGS. 1 to 4, only the fibers 22 extending along the extending direction of the base material 20 are shown. The fiber 22 extended along the direction orthogonal to the extending direction of 20 and the fiber 22 extended along arbitrary directions may be contained.

  As illustrated, the coating film layer 30 includes a plurality of extending directions along at least one of an extending direction of the base material 20 (left and right direction on the paper surface) and a direction orthogonal to the direction (up and down direction on the paper surface). A through hole 32 is provided. 5 and 6 show only the through hole 32 extending along the extending direction of the base material 20 as an example. The through holes 32 expose the plurality of fibers 22 included in the base material 20 under the coating layer 30.

  As the resin contained in the base material 20 flows out through the through holes 32 of the coating layer 30, the fibers 22 contained in the base material 20 enter this region as shown in FIG. The coating layer 30 is in close contact. Alternatively, the coating film layer 30 is in close contact with the fibers 22 by the penetration of the coating film layer 30 into the voids generated by the outflow of the resin in the substrate 20. Thus, when the fiber 22 contained in the base material 20 and the coating film layer 30 are in close contact, the coating film layer 30 expresses the shade of the color along the fiber 22 in close contact therewith.

  Moreover, the through-hole (break) 32 of the coating film layer 30 also extends along the direction in which the fibers 22 that are in close contact therewith extend. The part of the through-hole 32 in the coating film layer 30 is a part where coating is not present, and the other part of the coating film layer 30 is a part where coating is present. Therefore, the coating layer 30 causes the presence or absence of coating along the fibers 22 included in the substrate 20.

  Thus, since the coating-film layer 32 is closely_contact | adhering to the fiber contained in the base material 20 arrange | positioned under it, the texture of a fiber can be expressed. Thereby, the coating film layer 32 can express the external appearance which looks like a natural material (for example, bamboo).
