Abstract
Description
[Technical field]
[0001] The present invention relates to a fishing guide frame and a manufacturing method for the fishing guide frame. [Background technology]
[0002] In a conventional fishing guide frame, the frame body is formed using a prepreg sheet in which reinforcing fibers are arranged in a predetermined direction (for example, see Patent Document 1). Furthermore, for example, Patent Document 2 discloses a fishing guide frame in which unevenness is formed on the outer peripheral surface of the frame body by using ceramic. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] JP 2020-137454 A [Patent Document 2] Japanese Patent Application Publication No. 7-3549 Summary of the Invention [Problem to be solved by the invention]
[0004] However, in the fishing guide frame as shown in the above-mentioned Patent Document 2, the unevenness is formed from ceramic and is arranged irregularly, which causes air turbulence on the surface, resulting in large air resistance and causing the frame to shake when the fishing rod is swung, which in turn causes the fishing rod to shake when it is swung.In addition, the outer surface of the frame body cannot be made to have a sufficient water-repellent effect. Therefore, there is a demand for a fishing guide frame that can reduce frame vibration by preventing turbulence from occurring on the surface, and thus reduce vibration when the fishing rod is swung, and that also has a high water-repellent effect in environments where it comes into contact with water, such as fishing guide frames, and there is room for improvement in this regard.
[0005] The present invention has been made in consideration of these circumstances, and its purpose is to provide a fishing guide frame and a manufacturing method for a fishing guide frame that can increase water repellency and prevent turbulent air currents from occurring on the surface, in other words, that can stabilize the air flow and control air resistance to reduce frame vibration, and ultimately minimize vibration when a fishing rod is swung. [Means for solving the problem]
[0006] (1) The fishing guide frame of the present invention is a fishing guide frame having a frame body that is fixed to the outer peripheral surface of a fishing rod and holds a guide ring through which a fishing line is inserted, and is characterized in that the frame body is molded from a fiber-reinforced resin containing reinforcing fibers, and a plurality of convex portions are formed on the surface of the frame body.
[0007] According to the fishing guide frame of the present invention, by using a fiber-reinforced resin containing reinforcing fibers, the reinforcing fibers are easily allowed to flow into the multiple convex portions on the surface of the frame body during manufacturing. Therefore, the filling rate of the reinforcing fibers in the multiple convex portions can be increased, and multiple small convex portions are formed on the frame body. Since multiple small convex portions are provided on the frame body in this manner, the fishing guide frame can be made water-repellent. Furthermore, in the present invention, by forming multiple convex portions on the frame body, the generation of turbulent airflows on the surface can be suppressed, so that the air resistance can be controlled to a constant level, the shaking of the frame can be reduced, and the shaking of the fishing rod can be reduced.
[0008] (2) The plurality of protrusions may be arranged at equal intervals.
[0009] In this case, since the multiple protrusions are aligned at equal intervals, the wind direction is uniform when the fishing rod is swung, and the air resistance is constant. Therefore, the wobble of the fishing rod due to air resistance can be more reliably suppressed.
[0010] (3) The distance between adjacent protrusions may be 8 to 12 μm.
[0011] In this case, the frame body is formed with an uneven surface having surface roughness that produces a water-repellent function, thereby further enhancing the water-repellent effect.
[0012] (4) The surface roughness of the frame body formed by the plurality of protrusions may be 8 to 12 μm.
[0013] In this case, the frame body is formed with an uneven surface having surface roughness that produces a water-repellent function, thereby further enhancing the water-repellent effect.
[0014] (5) The fiber reinforced resin may be a resin in which at least one of the directions and lengths of the reinforcing fibers is irregular.
[0015] In this case, by using a fiber-reinforced resin containing at least one of the directions, length, and direction of the reinforcing fibers irregularly, the reinforcing fibers can flow more easily into the minute protrusions during manufacturing. Therefore, the filling rate of the reinforcing fibers in the multiple protrusions can be further increased, and the strength of the frame body itself can be improved. Therefore, the strength of the fishing guide frame as a whole can be efficiently strengthened.
[0016] (6) The fiber-reinforced resin may be a prepreg sheet formed by laminating a plurality of prepreg sheets, and the frame body may be formed by applying heat and pressure to the prepreg sheets.
[0017] In this case, by providing a plurality of layers of prepreg sheets, the reinforcing fibers can be thoroughly filled into the plurality of protruding portions during manufacturing.
[0018] (7) The manufacturing method of the fishing guide frame according to the present invention is a manufacturing method of the fishing guide frame described in any one of (1) to (6) above, characterized by comprising the steps of: setting a first mold having a plurality of recesses forming the plurality of convex portions, and a second mold opposite the first mold; placing a prepreg sheet having the plurality of laminated layers of the fiber reinforced resin between the first mold and the second mold; and heating the prepreg sheet and bringing the first mold and the second mold close to each other to press the prepreg sheet against the first mold to apply pressure, thereby causing the prepreg sheet to flow inside the plurality of recesses.
[0019] According to the manufacturing method of the fishing guide frame of the present invention, the manufactured fishing guide frame has the same effect as that of claim 1. That is, during manufacturing, the reinforcing fibers contained in the fiber reinforced resin are thoroughly filled into the multiple recesses of the first mold, so that the frame body can have sufficient water repellency and air resistance. Effect of the Invention
[0020] According to the fishing guide frame and the manufacturing method of the fishing guide frame of the present invention, it is possible to increase water repellency and further prevent turbulence occurring on the surface, in other words, to stabilize the air flow and control the air resistance, thereby reducing the shaking of the frame and ultimately reducing the shaking when the fishing rod is swung. It is possible to increase water repellency and further reduce the shaking when the fishing rod is swung by providing air resistance. [Brief description of the drawings]

[0022] Hereinafter, the fishing guide frame and the manufacturing method thereof according to the present invention will be described with reference to the drawings. In each drawing, the scale of each component may be appropriately changed as necessary to make each component visible.
[0023] As shown in Figures 1 and 2, the fishing guide frame 1 of this embodiment is fixed to the outer peripheral surface of a fishing rod (not shown) and is configured to hold a guide ring 3 (shown by a two-dot chain line in Figure 1) through which a fishing line is inserted.
[0024] As shown in Fig. 3, the fishing guide frame 1 includes a frame body 10 and a reinforcing rib 20 that protrudes from and is integrally molded with the frame body 10. As shown in Fig. 1, the frame body 10 includes a ring holder 11 that holds the guide ring 3 on its inner peripheral surface, and support legs 12 that support the ring holder 11 by extending in a direction away from the outer peripheral surface of the fishing rod.
[0025] 1 is a front view of the fishing rod tip viewed from the butt of the fishing guide frame 1, with the longitudinal direction of the support leg 12 (hereinafter referred to as the axial direction X) coinciding with the axial direction of the fishing rod when the fishing guide frame 1 is fixed to the fishing rod. In the fishing guide frame 1, the direction facing the butt of the fishing rod is called the front side or forward, and the direction facing from the butt of the fishing rod to the tip of the fishing rod is called the rear side or rear.
[0026] A plurality of ring holders 11 are arranged at predetermined intervals in the rod axis direction on the outer circumferential surface of the fishing rod. The ring holder 11 holds a guide ring 3, which guides the fishing line, on its inner circumferential surface at a position away from the outer circumferential surface of the fishing rod. The ring holder 11 is formed in an annular shape and has a circular holding hole 11a that holds the guide ring 3. The ring holder 11 rises forward from one end of the support leg 12 via a curved portion W (a second curved portion Wb, described later) relative to the outer circumferential surface of the fishing rod.
[0027] The guide ring 3, which is held coaxially in the holding hole 11a, is formed in an annular shape, and its inner circumferential guide surface is made of a material that provides low sliding resistance to the fishing line, such as titanium, aluminum, SUS, ceramics, etc. The guide ring 3 is integrally formed with a fiber reinforced resin 14, which will be described later, that forms the frame body 10.
[0028] The fishing guide frame 1 is fixed to the outer circumferential surface of the fishing rod with the ring holder 11 facing the rod tip relative to the support leg 12. At this time, the support leg 12 extends in one direction (axial length direction X), and the axial length direction X coincides with the rod axis direction of the fishing rod.
[0029] The contact surface 12a (see Figs. 2 and 3) on the back side of the support leg 12 is placed on the outer circumferential surface of the fishing rod and is fixed thereto by a line fastener, adhesive, etc. The support leg 12 has approximately the same width dimension along the axial direction X.
[0030] 3, the reinforcing rib 20 is provided over the entire surface of the rear surface 10b of the frame main body 10. In this embodiment, the reinforcing rib 20 is provided only on the rear surface 10b of the frame main body 10, but is not limited to the rear surface 10b, and may be provided on the front surface 10a (see FIG. 1) of the frame main body 10, or may be provided on both the front surface 10a and the rear surface 10b.
[0031] 3, the reinforcing rib 20 has an outer peripheral rib 21 provided along the outer peripheral edges of the ring holding portion 11 and the support leg portion 12, an inner peripheral rib 22 provided along the inner peripheral edge where the holding hole 11a of the ring holding portion 11 is formed, and an intermediate rib 23 provided between a pair of left and right outer peripheral ribs 21 arranged on the support leg portion 12. The intermediate rib 23 extends to the ring holding portion 11 side and is connected to the inner peripheral rib 22.
[0032] 2 and 3, the curved portion W formed in the frame body 10 has a first curved portion Wa formed on the outer periphery of the ring holding portion 11 and a second curved portion Wb formed on the boundary between the ring holding portion 11 and the support leg portion 12. The first curved portion Wa is formed by a curved surface that follows the ring shape of the ring holding portion 11. The first curved portion Wa and the second curved portion Wb are also formed from a fiber reinforced resin 14 having reinforcing fibers 13 with irregular directions and lengths. Here, in this embodiment, the first curved portion Wa and the second curved portion Wb are set to a curved surface having one radius of curvature.
[0033] As shown in Fig. 4, a plurality of protrusions 10A are formed on the front surface 10a (surface) of the frame main body 10. Each protrusion 10A is rectangular (square in this case) when viewed from the front, and protrudes from the front surface 10a of the frame main body 10. The plurality of protrusions 10A are aligned at equal intervals vertically and horizontally. Here, the vertical direction X1 of the frame main body 10 is the up-down direction in Fig. 4, and the horizontal direction X2 is the left-right direction in Fig. 4. The symbol D shown in Fig. 4 is the distance between the protrusions 10A, 10A. The interval between adjacent protrusions 10A, 10A is set to 8 to 12 μm. Furthermore, the surface roughness of the frame body 10 formed by the multiple protrusions 10A is set to 8 to 12 μm.
[0034] As shown in FIG. 5, the frame body 10, the reinforcing rib 20 (see FIG. 3), and the multiple protrusions 10A formed on the front surface 10a of the frame body 10 are formed from a fiber-reinforced resin 14 containing reinforcing fibers 13 having irregular directions and lengths. The fiber-reinforced resin 14 is a sheet-like prepreg sheet 15 (see FIGS. 6 to 8) that is laminated in multiple layers. The reinforcing fibers 13 are carbon fibers, glass fibers, or the like. As described above, the reinforcing fibers 13 of this embodiment do not have a constant fiber direction or length, but have irregular fiber directions and lengths. The fiber-reinforced resin 14 is configured by impregnating the reinforcing resin 13 with a thermosetting resin (e.g., epoxy resin) or a thermoplastic resin (e.g., nylon) as a matrix resin. The frame body 10 and the reinforcing rib 20 are formed by heating and pressurizing the prepreg sheet 15 by press processing.
[0035] Next, a method for manufacturing the above-mentioned fishing guide frame will be specifically described with reference to the drawings. As shown in Figs. 6 to 8, the fishing guide frame 1 of this embodiment is formed of a frame body 10, a reinforcing rib 20, and a fiber-reinforced resin 14 made of a prepreg sheet 15 having reinforcing fibers 13 with irregular directions and lengths, in which a plurality of protrusions 10A are formed on the front surface 10a of the frame body 10 as described above. In preparation for manufacture, the prepreg sheet 15 is cut into a predetermined shape and stacked to form a plurality of layers. The number of layers of the prepreg sheets 15 to be stacked can be set as appropriate. The number of layers of the prepreg sheet 15 is determined according to conditions such as the load acting on the fishing guide frame 1 during use and the bending characteristics of the fishing rod. The prepreg sheet 15 used here is a general reinforced plastic molding material in which reinforcing fibers 13 such as carbon fibers or glass fibers are evenly impregnated with a thermosetting resin such as epoxy and then heated or dried to a semi-hardened state.
[0036] As shown in Figure 6, first, a first mold 41 having a plurality of recesses 41a for forming the convex shapes of the plurality of protrusions 10A formed on the front surface 10a of the frame body 10, and a second mold 42 that can be brought close to the first mold 41 are set. The mold 4 used has, for example, a first mold 41 and a second mold 42 divided into upper and lower halves. A prepreg sheet 15, which is a laminate of a plurality of sheets, is set between the first mold 41 and the second mold 42. A mold release agent is applied to the first mold 41 and the second mold 42. The direction in which the first mold 41 and the second mold 42 are divided is not limited to the vertical direction, and they may be divided in the left-right direction or in an oblique direction according to the shape of the fishing guide frame 1.
[0037] 7, a plurality of laminated prepreg sheets 15 are placed on the mold surface of a first mold 41. At this time, the guide ring 3 shown in FIG.
[0038] After the prepreg sheet 15 is set in the first mold 41, the prepreg sheet 15 is heated and the second mold 42 is pressed against the prepreg sheet 15 to perform pressure molding. As a result, the prepreg sheet 15 is compressed by receiving a compressive force in the thickness direction (pressure direction), and the prepreg sheet 15 flows into the inside of the multiple recesses 41a of the first mold 41. At this time, as shown in FIG. 5, the direction and length of the reinforcing fibers 13 contained in the flowing fiber reinforced resin 14 are not constant but irregular, so that the entire recesses 41a are filled. In addition, the guide holding portion 11 and the guide ring 3 are heat fused or heat bonded by heating and pressure.
[0039] Thereafter, the first mold 41 and the second mold 42 are demolded and the molded product is taken out from the molds, thereby manufacturing the fishing guide frame 1 as shown in Figs. 1 to 3.
[0040] Next, the operation of the fishing guide frame thus constructed and the method for manufacturing the fishing guide frame will be described in detail with reference to the drawings.
[0041] 4 and 5, in this embodiment, by using fiber reinforced resin 14 containing reinforcing fibers 13, during manufacturing, the reinforcing fibers 13 tend to flow into the multiple protruding portions 10A on the front surface 10a of the frame body 10. Therefore, the filling rate of the reinforcing fibers 13 in the multiple protruding portions 10A can be increased, and a minutely uneven surface is formed on the frame body 10. In this way, since the frame body 10 is provided with a plurality of minute protrusions 10A, it is possible to impart water repellency to the fishing guide frame 1. Furthermore, in this embodiment, by forming a plurality of protrusions 10A on the frame body 10, it is possible to impart air resistance, and it is possible to minimize the shaking of the fishing rod.
[0042] In addition, in this embodiment, the multiple protrusions 10A formed on the front surface 10a of the frame body 10 are aligned at equal intervals, so that when the fishing rod is swung, the wind direction is uniform and the air resistance is constant. Therefore, the shaking of the fishing rod due to air resistance can be more reliably suppressed.
[0043] Furthermore, in this embodiment, the distance D between adjacent convex portions 10A, 10A is set to 8 to 12 μm, and an uneven surface with surface roughness that creates a water-repellent function is formed on the frame body 10, thereby further enhancing the water-repellent effect.
[0044] Furthermore, in this embodiment, the surface roughness of the frame body 10 formed by the multiple convex portions 10A is set to 8 to 12 μm, and an uneven surface with a surface roughness that produces a water-repellent function is formed on the frame body 10, thereby further enhancing the water-repellent effect.
[0045] In addition, in this embodiment, by using the fiber reinforced resin 14 containing the reinforcing fibers 13 with irregular lengths and directions, the reinforcing fibers 13 can flow more easily into the minute protrusions 10A during manufacturing. Therefore, the filling rate of the reinforcing fibers 13 in the multiple protrusions 10A can be further increased, and the strength of the frame body 10 itself can be improved. Therefore, the strength of the fishing guide frame 1 as a whole can be efficiently increased.
[0046] Furthermore, in this embodiment, the fiber reinforced resin 14 is a prepreg sheet 15 formed by laminating multiple layers, and the frame body 10 is formed by heating and pressurizing the prepreg sheet 15. By providing multiple layers of prepreg sheets 15 in this manner, the reinforcing fibers 13 can be sufficiently filled into the multiple protrusions 10A during manufacturing.
[0047] The fishing guide frame and the manufacturing method for the fishing guide frame according to this embodiment configured as described above can enhance water repellency, and furthermore, by suppressing the generation of turbulent air currents on the surface, the air resistance can be controlled to a constant level, reducing the shaking of the frame and ultimately minimizing the shaking of the fishing rod.
[0048] The above describes the embodiments of the fishing guide frame and the manufacturing method of the fishing guide frame according to the present invention, but these embodiments are presented as examples and are not intended to limit the scope of the invention. The embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the gist of the invention. The embodiments and their modifications include, for example, those that can be easily imagined by a person skilled in the art, those that are substantially the same, those that are within the scope of equivalents, and the like.
[0049] For example, in this embodiment, the reinforcing fibers 13 contained in the fiber reinforced resin 14 have irregular fiber directions and lengths, but the fibers may have a constant fiber direction and length. Alternatively, the fiber reinforced resin may contain reinforcing fibers at least having irregular directions.
[0050] In the above embodiment, the frame body 10 has a configuration in which a plurality of protrusions 10A are provided on the front surface 10a, but this is not limited to the front surface 10a, and the protrusions 10A may be provided on both the front surface 10a and the rear surface 10b of the frame body 10. Furthermore, the protrusions 10A may be provided only on the ring holding portion 11 or only on the support leg portion 12. Furthermore, the multiple convex portions 10A are not limited to being aligned vertically and horizontally; for example, the flat portions may be arranged so that the spacing D is smaller than that of the curved portions, or they may be arranged so that they are aligned diagonally relative to the frame body 10 when viewed from the front.
[0051] In addition, in this embodiment, the distance D between adjacent protrusions 10A, 10A is set to 8 to 12 μm, and the surface roughness of the frame body 10 formed by the multiple protrusions 10A is set to 8 to 12 μm, but is not limited to these dimensions.
[0052] Furthermore, although the fishing guide frame 1 of this embodiment has a frame body 10 and a reinforcing rib 20, the present invention is also applicable to fishing guide frames that omit the reinforcing rib 20. In addition, there are no limitations on the specific configuration of the reinforcing rib, such as its cross-sectional shape, extension direction, and arrangement. [Explanation of symbols]
