Description

The present invention relates to a fishing guide frame and a method of manufacturing a fishing guide frame.

BACKGROUND ART As a conventional fishing guide frame, a frame body is molded using a prepreg sheet in which reinforcing fibers are arranged in a predetermined direction (see, for example, Patent Document 1).
Further, Patent Document 2, for example, describes a fishing guide frame in which irregularities are formed by ceramic on the outer peripheral surface of the frame body.

JP 2020-137454 A JP-A-7-3549

However, in the fishing guide frame as shown in the above-mentioned Patent Document 2, since the unevenness is formed of ceramic, the unevenness is arranged irregularly. becomes large, the frame shakes when the rod is swung, and eventually the rod being swung shakes, and the outer peripheral surface of the frame body cannot have a sufficient water-repellent effect.
Therefore, by preventing the turbulence that occurs on the surface, it is possible to reduce the shake of the frame, which in turn reduces the shake when swinging the fishing rod. There is a demand for a fishing guide frame with a high water effect, and there is room for improvement in this respect.

The present invention has been made in consideration of such circumstances, and its purpose is to improve water repellency and prevent turbulence generated on the surface, that is, to stabilize the air flow. To provide a fishing guide frame and a method for manufacturing a fishing guide frame capable of suppressing shaking of a frame by controlling air resistance and further suppressing shaking when a fishing rod is swung. .

(1) A fishing guide frame according to 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, wherein the frame body is made of reinforced fiber. It is characterized in that the frame body is molded from a fiber-reinforced resin containing and has a plurality of projections formed on the surface of the frame body.

According to the fishing guide frame of the present invention, by using a fiber-reinforced resin containing reinforcing fibers, the reinforcing fibers can easily flow into the plurality of protrusions on the surface of the frame body during manufacturing. Therefore, the filling rate of the reinforcing fibers in the plurality of projections can be increased, and a plurality of minute projections are formed on the frame main body. Since the frame main body is provided with a plurality of minute protrusions in this manner, the fishing guide frame can be provided with water repellency. Furthermore, in the present invention, by forming a plurality of projections on the frame body, turbulence that occurs on the surface can be suppressed, so that the air resistance can be controlled to be constant, and the vibration of the frame can be reduced. As a result, the shaking of the fishing rod can be suppressed.

(2) The plurality of projections may be arranged at regular intervals.

In this case, since the plurality of projections are arranged at regular intervals, the air resistance becomes constant when the fishing rod is swung with the wind blowing in a constant direction. Therefore, it is possible to more reliably suppress the shaking of the fishing rod due to air resistance.

(3) The distance between adjacent projections may be 8 to 12 μm.

In this case, the frame main body is formed with an uneven surface having a surface roughness that produces a water-repellent function, so that the water-repellent effect can be further enhanced.

(4) The surface roughness of the frame main body composed of the plurality of projections may be 8 to 12 μm.

In this case, the frame main body is formed with an uneven surface having a surface roughness that produces a water-repellent function, so that the water-repellent effect can be further enhanced.

(5) The fiber-reinforced resin may be characterized by being a resin containing the reinforcing fibers irregularly in at least the direction and the length thereof.

In this case, by using a fiber-reinforced resin in which at least one of the directions, lengths, and directions of the reinforcing fibers is irregular, the reinforcing fibers are more likely to flow into the minute protrusions during manufacturing. Therefore, the filling rate of the reinforcing fibers in the plurality of projections 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 reinforced.

(6) The fiber-reinforced resin may be a plurality of laminated prepreg sheets, and the frame body may be formed by heating and pressurizing the prepreg sheets.

In this case, by providing a plurality of layers of prepreg sheets, it is possible to sufficiently distribute and fill the reinforcing fibers into the plurality of protrusions during manufacturing.

(7) A fishing guide frame manufacturing method according to the present invention is the fishing guide frame manufacturing method according to any one of (1) to (6) above, wherein the plurality of convex portions are formed. a step of setting a first mold having a plurality of recesses and a second mold so as to face the first mold; placing between the second mold, heating the prepreg sheet, bringing the first mold and the second mold close to each other, and pressing the prepreg sheet against the first mold. and a step of causing the prepreg sheet to flow inside the plurality of recesses by applying pressure to the recesses.

According to the manufacturing method of the fishing guide frame according to the present invention, the manufactured fishing guide frame has the same function and effect as the first aspect. That is, since the reinforcing fibers contained in the fiber-reinforced resin are thoroughly filled into the plurality of concave portions of the first mold during manufacturing, the frame main body can be provided with sufficient water repellency and air resistance.

According to the fishing guide frame and the manufacturing method of the fishing guide frame according to the present invention, it is possible to improve the water repellency and further prevent turbulence generated on the surface, that is, stabilize the air flow. By controlling the air resistance, it is possible to reduce the shake of the frame, and in turn, it is possible to increase the water repellency that can suppress the shake when the fishing rod is swung. It is possible to suppress the blurring at the time.
