Therefore, a guide ring holder for fishing equipment is desired which can reduce the wobbling of the holder by preventing the occurrence of turbulence on the surface, which can reduce the wobbling when the fishing rod is swung, and which has a high waterproof effect in a use environment where water is in contact like the guide ring holder for fishing equipment, and there is still room for improvement in this regard.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a guide ring holder for a fishing tackle and a method for manufacturing the guide ring holder for a fishing tackle, which can improve waterproofness and prevent generation of turbulence on the surface, that is, reduce the shaking of the holder by stabilizing the airflow and controlling the air resistance, and further suppress the shaking at the time of swinging a fishing rod to a small degree.

Means for solving the problems

(1) The guide ring holder for a fishing tackle according to the present invention is a guide ring holder for a fishing rod, which is fixed to an outer peripheral surface of the fishing rod and has a holder main body for holding a guide ring into which a fishing line is inserted, wherein the holder main body is molded from a fiber-reinforced resin containing a reinforcing fiber, and a plurality of protrusions are formed on a surface of the holder main body.

According to the guide ring holder for a fishing tackle of the present invention, the fiber-reinforced resin containing the reinforcing fiber is used, so that the reinforcing fiber is easily flowed into the plurality of protrusions on the surface of the holder body during the production. Therefore, the filling rate of the reinforcing fibers of the plurality of projections can be increased, and the plurality of minute projections can be formed on the stent body. In this way, since the plurality of minute protrusions are provided on the holder main body, the fishing tackle guide ring holder can be provided with waterproofness. Further, in the present invention, by forming a plurality of projections on the holder main body, it is possible to suppress the occurrence of turbulence on the surface, to fix the holder by controlling the air resistance, to reduce the shaking of the holder, and to suppress the shaking of the fishing rod to a small level.

(2) The invention may also have the following features: the plurality of projections are arranged regularly at equal intervals.

In this case, since the plurality of projections are aligned at equal intervals, the air flow direction is constant when the fishing rod is swung, and the air resistance is also constant. Therefore, the fishing rod can be more reliably restrained from shaking due to air resistance.

(3) The invention may also have the following features: the interval between the adjacent projections is 8 to 12 μm.

In this case, since the concave-convex surface having the surface roughness having the waterproof function is formed on the holder main body, the waterproof effect can be further improved.

(4) The invention also has the following features: the surface roughness of the stent body composed of the plurality of projections is 8 to 12 μm.

(5) The invention also has the following features: the fiber-reinforced resin is a resin containing the reinforcing fibers having irregularities in at least one of direction and length.

In this case, by using a fiber-reinforced resin containing reinforcing fibers having irregular directions and lengths, the reinforcing fibers can more easily flow into the minute convex portions during production. Therefore, the filling rate of the reinforcing fibers in the plurality of projections can be further increased, and the strength of the stent body itself can be increased. Therefore, the strength of the entire guide ring holder for a fishing tackle can be effectively increased.

(6) The invention also has the following features: the fiber-reinforced resin is a prepreg sheet in which a plurality of layers are stacked, and the stent body is molded by heating and pressurizing the prepreg sheet.

In this case, by providing a plurality of prepreg sheets, it is possible to sufficiently reach and fill the plurality of convex portions with the reinforcing fibers during production.

(7) A method of manufacturing a guide ring bracket for a fishing tackle according to the present invention is the method of manufacturing a guide ring bracket for a fishing tackle according to any one of the above (1) to (6), including the steps of: arranging a first die and a second die, wherein the first die is provided with a plurality of concave parts for forming the plurality of convex parts, and the second die is arranged opposite to the first die; disposing a prepreg sheet in which a plurality of the fiber-reinforced resins are laminated 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 and pressurize the prepreg sheet, thereby causing the prepreg sheet to flow to the inside of the plurality of concave portions.

The guide ring holder for fishing tackle produced by the method for producing a guide ring holder for fishing tackle of the present invention has the same operational advantages as in claim 1. That is, in the manufacturing process, the reinforcing fibers contained in the fiber-reinforced resin sufficiently reach and fill the plurality of concave portions of the first mold, and therefore, the holder main body can be made to have sufficient water resistance and air resistance.

In the drawings, the proportions of the respective components may be appropriately changed as necessary in order to make the respective components visually recognizable.

As shown in fig. 1 and 2, a guide ring holder 1 for a fishing tackle according to the present embodiment is fixed to an outer peripheral surface of a fishing rod (not shown) and configured to hold a guide ring 3 (a two-dot chain line shown in fig. 1) through which a fishing line is inserted.

As shown in fig. 3, the guide ring holder 1 for a fishing tackle includes a holder main body 10 and a reinforcing rib 20 integrally formed to protrude from the holder main body 10. As shown in fig. 1, the stent main body 10 includes: a ring holding portion 11 that holds the guide ring 3 on an inner peripheral surface; and a support leg portion 12 that extends in a direction away from the outer peripheral surface of the fishing rod and supports the ring holding portion 11.

In fig. 1, a front view of the tip of the rod is seen from the rod end, and the longitudinal direction of the supporting leg 12 (hereinafter referred to as the longitudinal direction X) coincides with the rod axis direction of the fishing rod in a state where the guide ring holder 1 for fishing equipment is fixed to the fishing rod. In the guide ring holder 1 for fishing tackle, the direction toward the rod tail side is referred to as the front side, and the direction from the rod tail toward the rod tip side is referred to as the rear side.

A plurality of ring holding portions 11 are disposed on the outer peripheral surface of the fishing rod at predetermined intervals along the rod axis direction. The ring holding portion 11 holds the guide ring 3 on the inner peripheral surface, and the guide ring 3 guides the fishing line at a position away from the outer peripheral surface of the fishing rod. The ring holding portion 11 is formed in an annular shape and has a circular holding hole 11a for holding the guide ring 3. The ring holding portion 11 is erected forward from one end of the supporting leg portion 12 via a bent portion W (a second bent portion Wb described later) with respect to the rod outer peripheral surface.

The guide ring 3 held coaxially with the holding hole 11a is formed in an annular shape, and its inner peripheral guide surface is formed of a material having a small sliding resistance against the fishing line, such as titanium, aluminum, SUS, or ceramics. The guide ring 3 is formed integrally with a fiber-reinforced resin 14 described later that forms the stent body 10.

The guide ring holder 1 for fishing tackle is fixed to the outer peripheral surface of the fishing rod in a state where the ring holding portion 11 faces the rod tip side with respect to the supporting leg portion 12. At this time, the supporting leg 12 extends in one direction (long axis direction X) which coincides with the rod axis direction of the fishing rod.

The abutment surface 12a (see fig. 2 and 3) on the back side of the supporting leg 12 is fixed by tying, bonding, or the like in a state of being placed on the outer peripheral surface of the fishing rod. The width dimensions of the support feet 12 in the long axis direction X are substantially the same.

As shown in fig. 3, the reinforcing rib 20 is provided over the entire back surface 10b of the holder main body 10. In the present embodiment, the reinforcing rib 20 is provided only on the back surface 10b of the holder main body 10, but is not limited to the back surface 10b, and may be provided on the front surface 10a (see fig. 1) of the holder main body 10, or may be provided on both the front surface 10a and the back surface 10 b.

As shown in fig. 3, the reinforcing rib 20 has: an outer circumferential rib 21 provided along the outer circumferential edges of the ring holder 11 and the support leg 12; an inner circumferential rib 22 provided along an inner circumferential edge of the ring holding portion 11 in which the holding hole 11a is formed; and an intermediate rib 23 provided between the pair of left and right outer circumferential ribs 21 disposed on the supporting leg portion 12. The intermediate rib 23 extends up to the ring holding portion 11 side and is connected to the inner circumferential rib 22.

As shown in fig. 2 and 3, the bent portion W formed in the holder body 10 includes: a first curved section Wa formed at an outer peripheral portion of the ring holding section 11; and a second bent portion Wb formed at a boundary portion between the ring holding portion 11 and the support foot 12. The first curved section Wa is formed by a curved surface along the ring shape of the ring holding portion 11.

The first curved section Wa and the second curved section Wb are also molded from a fiber-reinforced resin 14 containing reinforcing fibers 13 having irregular directions and lengths. In the present embodiment, the first curved section Wa and the second curved section Wb are provided as curved surfaces having one radius of curvature.

As shown in fig. 4, a plurality of projections 10A are formed on the front surface 10A (front surface) of the holder main body 10. Each of the projections 10A is rectangular (here, square) in front view, and protrudes from the front face 10A of the holder main body 10. These plurality of projections 10A are aligned at equal intervals in the vertical and horizontal directions. Here, the longitudinal direction X1 of the stent main body 10 is the up-down direction in fig. 4, and the lateral direction X2 is the left-right direction in fig. 4. Symbol D shown in fig. 4 indicates the interval between the

convex portions

10A, 10A.

The interval between the

adjacent projections

10A, 10A is set to 8 μm to 12 μm. Further, the surface roughness of the stent body 10 composed of the plurality of projections 10A is set to 8 μm to 12 μm.

As shown in fig. 5, the holder main body 10, the reinforcing ribs 20 (see fig. 3), and the plurality of projections 10A formed on the front surface 10A of the holder main body 10 are molded with 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 fig. 6 to 8) in which a plurality of layers are stacked. The reinforcing fibers 13 are carbon fibers, glass fibers, or the like. As described above, the direction and length of the fibers of the reinforcing fibers 13 of the present embodiment are not constant, and the direction and length of the fibers are irregular. The fiber-reinforced resin 14 is formed by impregnating the reinforcing fibers 13 with a thermosetting resin (e.g., epoxy resin) or a thermoplastic resin (e.g., nylon) as a matrix resin. The holder body 10 and the reinforcing ribs 20 are formed by pressing the prepreg sheet 15 under heat and pressure.

Next, a method for manufacturing the guide ring holder for fishing tackle will be described in detail with reference to the drawings.

As shown in fig. 6 to 8, in the guide ring holder 1 for a fishing tackle according to the present embodiment, as described above, the holder main body 10, the reinforcing ribs 20, and the plurality of protrusions 10A formed on the front surface 10A of the holder main body 10 are formed of the fiber-reinforced resin 14, and the fiber-reinforced resin 14 is formed of the prepreg sheet 15 containing the reinforcing fibers 13 having irregular directions and lengths. As a preparation for production, the prepreg sheet 15 is cut into a predetermined shape, and stacked in a plurality of layers. The number of prepreg sheets 15 to be stacked (the number of layers) can be set as appropriate. The number of layers of the prepreg sheet 15 is determined according to conditions such as a load applied to the guide ring holder 1 for a fishing tackle or a rod bending property during use.

As the prepreg sheet 15 used here, a general reinforced plastic molding material can be used, in which reinforcing fibers 13 such as carbon fibers and glass fibers are uniformly impregnated with a thermosetting resin such as an epoxy resin, and are semi-cured by heating or drying.

As shown in fig. 6, first, a first mold 41 having a plurality of concave portions 41a for forming the convex shape of the plurality of convex portions 10A formed on the front surface 10A of the stent body 10 and a second mold 42 capable of approaching the first mold 41 are provided.

The mold 4 to be used has a structure having a first mold 41 and a second mold 42 divided into two in the vertical direction, for example. Between the first mold 41 and the second mold 42, a prepreg sheet 15 in which a plurality of layers are stacked is disposed. The first mold 41 and the second mold 42 are coated with a release agent. The dividing direction of the first mold 41 and the second mold 42 is not limited to the vertical direction, and may be divided in the horizontal direction or the oblique direction depending on the shape of the fishing tackle guide ring holder 1.

Next, as shown in fig. 7, a plurality of prepreg sheets 15 are stacked on the frame surface of the first mold 41. At this time, the guide ring 3 shown in fig. 1 is also set in advance in the first mold 41.

After the prepreg sheet 15 is set to the first mold 41, the prepreg sheet 15 is heated and press-molded by pressing the second mold 42 against the prepreg sheet 15. Thereby, the prepreg sheet 15 is compressed by receiving a compressive force in the thickness direction (pressing direction), and the prepreg sheet 15 flows into the inside of the plurality of concave portions 41a of the first mold 41. At this time, as shown in fig. 5, the reinforcing fibers 13 contained in the fiber-reinforced resin 14 flowing in are irregular in direction and length and are not fixed, and therefore, the entire concave portion 41a is filled. Further, the ring holding part 11 and the guide ring 3 are thermally fused or thermally bonded by heating and pressing.

Thereafter, the first mold 41 and the second mold 42 are released from each other, and the molded article is taken out from the molds, thereby manufacturing the guide ring holder 1 for fishing tackle as shown in fig. 1 to 3.

Next, the operation of the guide ring holder for a fishing tackle and the method for manufacturing the guide ring holder for a fishing tackle, which are configured in this manner, will be described in detail with reference to the drawings.

In the present embodiment, as shown in fig. 4 and 5, by using the fiber-reinforced resin 14 containing the reinforcing fibers 13, the reinforcing fibers 13 easily flow into the plurality of convex portions 10A of the front surface 10A of the stent body 10 during the production. Therefore, the filling rate of the reinforcing fibers 13 in the plurality of convex portions 10A can be increased, and a minute uneven surface can be formed on the holder main body 10.

As described above, since the plurality of minute protrusions 10A are provided on the holder body 10, the fishing guide ring holder 1 can be provided with waterproofness. Further, in the present embodiment, the plurality of projections 10A are formed on the holder main body 10, so that air resistance can be provided, and the wobbling of the fishing rod can be suppressed.

In the present embodiment, since the plurality of projections 10A formed on the front surface 10A of the holder main body 10 are aligned at equal intervals, the air flow direction is constant when the fishing rod is swung, and the air resistance is also constant. Therefore, the fishing rod can be more reliably restrained from swaying due to air resistance.

Further, in the present embodiment, the interval D between the adjacent

convex portions

10A and 10A is set to 8 μm to 12 μm, and the surface roughness of the concave-convex surface capable of generating the water-repellent function is formed on the holder main body 10, so that the water-repellent effect can be further improved.

In the present embodiment, the surface roughness of the stent body 10 formed of the plurality of convex portions 10A is set to 8 μm to 12 μm, and the stent body 10 is formed with the uneven surface having the surface roughness capable of generating the water-repellent function, so that the water-repellent effect can be further improved.

In the present embodiment, by using the fiber-reinforced resin 14 containing the reinforcing fibers 13 having irregular lengths and directions, the reinforcing fibers 13 can more easily flow into the minute convex portions 10A during production. Therefore, the filling rate of the reinforcing fibers 13 in the plurality of projections 10A can be further increased, and the strength of the stent body 10 itself can be increased. Therefore, the strength of the entire fishing guide ring holder 1 can be effectively increased.

Further, in the present embodiment, the fiber-reinforced resin 14 is a prepreg sheet 15 in which a plurality of layers are laminated, and the stent body 10 is molded by heating and pressurizing the prepreg sheet 15. By providing a plurality of prepreg sheets 15 in this manner, the reinforcing fibers 13 can sufficiently reach and fill the plurality of convex portions 10A during production.

In the guide ring holder for a fishing tackle and the method of manufacturing the guide ring holder for a fishing tackle of the present embodiment configured as described above, the waterproof property can be improved, and the occurrence of turbulence on the surface can be suppressed, and the air resistance can be controlled to fix the guide ring holder, so that the wobbling of the holder can be reduced, and the wobbling of the fishing rod can be suppressed.

The embodiments may be implemented in other various manners, and various omissions, substitutions, and changes may be made without departing from the spirit of the invention. The embodiments and modifications thereof include, for example, substantially the same and equivalent embodiments as those of ordinary skill in the art can easily understand.

For example, in the present embodiment, as the reinforcing fibers 13 contained in the fiber-reinforced resin 14, fibers having irregular fiber directions and lengths are used, but fibers having fixed fiber lengths and directions may be used. Alternatively, the resin may be a fiber-reinforced resin containing reinforcing fibers having at least irregular directions.

In the above embodiment, the plurality of convex portions 10A are provided on the front surface 10A of the holder main body 10, but the configuration is not limited to the front surface 10A, and the convex portions 10A may be provided on both the front surface 10A and the back surface 10b of the holder main body 10. Further, the convex portion 10A may be provided only on the ring holding portion 11 or only on the supporting leg portion 12.

The plurality of projections 10A are not limited to being aligned in the vertical and horizontal directions, and may be arranged so that the interval D between the flat portions is smaller than the interval D between the curved portions, or may be aligned so as to be inclined with respect to the holder main body 10 in a front view, for example.

In the present embodiment, the distance D between the

adjacent projections

10A and 10A is set to 8 μm to 12 μm, and the surface roughness of the stent body 10 composed of the plurality of projections 10A is set to 8 μm to 12 μm, but the present invention is not limited to such a size.

Further, although the guide ring holder 1 for a fishing tackle according to the present embodiment has a structure including the holder main body 10 and the reinforcing rib 20, a guide ring holder for a fishing tackle, in which the reinforcing rib 20 is omitted, is also applicable. The cross-sectional shape, extending direction, arrangement, and the like of the reinforcing ribs are not limited to the specific configurations described above.
