However, in the guide ring stay for fishing equipment disclosed in patent documents 1 and 2, for example, when the stay body is manufactured, the reinforcing fibers aligned in a predetermined direction may not sufficiently flow into the bent portion located at the peripheral edge of the stay body. Therefore, there is a problem that the reinforcing fibers contained in the resin in the peripheral edge portion of the bent portion are insufficient, and the desired strength of the bent portion cannot be secured.
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 the strength of a bent portion and effectively enhance the strength of the entire guide ring holder for a fishing tackle.

According to the guide ring holder for a fishing tackle of the present invention, when a curved portion is provided at a part of the holder main body, the reinforcing fibers arranged in an irregular direction are easily flowed into the peripheral portion of the curved portion during manufacturing by using the fiber-reinforced resin containing the reinforcing fibers arranged in an irregular direction. Therefore, the filling rate of the reinforcing fibers in the bent portion can be increased, the bent portion where the reinforcing fibers can reach the peripheral edge portion can be molded, and the strength of the bent portion can be increased. Therefore, the strength of the entire guide ring holder for a fishing tackle can be effectively increased.
(2) Preferably, the fiber-reinforced resin contains reinforcing fibers having irregular lengths.
In this case, when the bent portion is provided in the bracket main body, the fiber-reinforced resin containing the reinforcing fibers having irregular directions and lengths is used, so that the reinforcing fibers having irregular directions and lengths can be more reliably flowed into the bent portion during the production. Therefore, the filling rate of the reinforcing fibers in the bent portion can be further increased, and the strength of the bent portion can be increased.
(3) The invention also has the following features: the curved portion is a curved surface having a radius of curvature.
In this case, the direction of the reinforcing fibers is irregular, and the reinforcing fibers are filled to a sufficient extent to reach the peripheral edge of the curved portion during production, so that a curved surface having a constant radius of curvature can be formed.
(4) The invention also has the following features: the fiber-reinforced resin is formed by laminating a plurality of prepreg sheets, and the stent body is molded by heating and pressing the prepreg sheets.
In this case, by providing a plurality of prepreg sheets, the reinforcing fibers can be filled to sufficiently reach the bent portion of the stent body during the production.
(5) A method of manufacturing a guide ring holder for fishing equipment according to the present invention is the method of manufacturing a guide ring holder for fishing equipment according to any one of the above items (1) to (4), comprising the steps of: providing a first mold having a concave curved portion for forming a curved shape of the curved portion and a second mold disposed opposite to the first mold; disposing a prepreg sheet in which a plurality of layers of the fiber reinforced resin are stacked 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 depressed curved portion.
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 actions and effects as those of claim 1. That is, at least the reinforcing fibers having irregular directions in the prepreg sheet are filled in the concave curved portion of the first mold during the production, and therefore sufficient strength can be secured in the curved portion.
Effects of the invention
According to the guide ring bracket for a fishing tackle and the method for manufacturing the guide ring bracket for a fishing tackle of the present invention, the strength of the bent portion can be increased, and the strength of the entire guide ring bracket for a fishing tackle can be effectively increased.

Detailed Description
Embodiments of a guide ring holder for a fishing tackle and a method for manufacturing the guide ring holder for a fishing tackle according to the present invention will be described below with reference to the accompanying drawings. In the drawings, the proportions of the respective components may be appropriately changed as necessary in order to make the respective components visually recognizable in size.
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 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 has: 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 apart 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 outer peripheral surface of the fishing rod.
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 of a 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 holder main 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 or bonding in a state of being placed on the outer peripheral surface of the fishing rod. The support legs 12 have substantially the same width dimension in the long axis direction X.
As shown in fig. 3 and 4, the reinforcing rib 20 is provided on the entire rear surface 10b of the bracket main body 10. In the present embodiment, the reinforcing rib 20 is provided only on the back surface 10b of the bracket 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 bracket body 10, or may be provided on both the front surface 10a and the back surface 10 b.
As shown in fig. 3, regarding the dimensions of the reinforcing rib 20, it 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 a center rib 23 provided between the pair of left and right outer circumferential ribs 21 disposed on the supporting leg 12. The intermediate rib 23 extends to the ring holding portion 11 side and connects with the inner circumferential rib 22. The reinforcing rib 20 has a height of about 0.1mm to 0.5mm and a width of about 0.3mm to 0.7mm, for example, and more specifically, has a rectangular cross section with a height of 0.3mm and a width of 0.5 mm.
As shown in fig. 5, the stent body 10 and the reinforcing ribs 20 are molded 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 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, in the reinforcing fiber 13 of the present embodiment, the direction and length of the fiber are not constant, and the direction and length of the fiber are irregular. The fiber-reinforced resin 14 is a structure in which the reinforcing fibers 13 are impregnated 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 heating and pressing the prepreg sheet 15 by press working.
The curved portion W formed in the stent 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 with 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 curved surfaces having one radius of curvature.
Next, the method of 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 stay 1 for fishing tackle according to the present embodiment, the stay body 10 and the reinforcing rib 20 are formed of the fiber-reinforced resin 14 as described above, 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 to be stacked. 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 and a bending characteristic of a fishing rod 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 concave portion 41a for forming the convex shape of the reinforcing rib 20 and a second mold 42 accessible to 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 plurality of layers of prepreg sheets 15 are stacked. 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 layers of prepreg sheets 15 are arranged 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 recessed portion 41a of the first mold 41. At this time, as shown in fig. 5, the reinforcing fibers 13 contained in the inflowing fiber-reinforced resin 14 are not fixed in direction and length but are irregular, and therefore, the entire concave portion 41a is filled. Further, the ring holding portion 11 and the guide ring 3 are thermally fused or thermally bonded by heating and pressing.
Further, as shown in fig. 10, in the first mold 41, at positions where the first bent portion Wa and the second bent portion Wb of the stent body 10 are formed, concave curved portions 41b are formed. In the second mold 42, a convex curved portion 42a is formed at a position opposed to the concave curved portion 41b of the first mold 41. After the prepreg sheet 15 having a plurality of layers stacked is placed on the mold frame surface of the first mold 41, the prepreg sheet 15 is heated, and the second mold 42 is pressed against the prepreg sheet 15 to perform press molding. 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 concave portion 41b 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 not fixed in irregular directions and lengths, and therefore, the entire concave curved portion 41b is filled. Further, the convex curved portion 42a of the second mold 42 is also filled with the reinforcing fibers 13, and is molded in a state where the reinforcing fibers 13 are uniformly arranged over the entire curved portion W.
Then, 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. 9 and 10, when the bent portion W (Wa, Wb) is provided in a part of the stent body 10, the reinforcing fibers 13 arranged irregularly in the direction during the production are easily flowed into the peripheral portions of the bent portion Wa and the bent portion Wb by using the fiber reinforced resin 14 containing the reinforcing fibers 13 having irregular directions and lengths. Therefore, the filling rate of the reinforcing fibers 13 in the bent portions Wa and Wb can be increased, the bent portions Wa and Wb at which the reinforcing fibers 13 can reach the peripheral edge portion can be molded, and the strength of the bent portions Wa and Wb can be increased. Therefore, the strength of the entire guide ring holder 1 for a fishing tackle can be effectively increased.
As described above, in the present embodiment, the direction and length of the reinforcing fibers 13 are irregular, and the reinforcing fibers 13 are filled to sufficiently reach the peripheral edges of the curved portion Wa and the curved portion Wb during the production, so that a curved surface having a constant radius of curvature can be formed.
Further, in the present embodiment, as shown in fig. 10, 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 be sufficiently filled in the portions of the bent portions Wa and Wb during production.
The guide ring bracket for fishing tackle and the method of manufacturing the guide ring bracket for fishing tackle of the present embodiment configured as described above can improve the strength of the bent portion Wa and the bent portion Wb, and can effectively enhance the strength of the entire guide ring bracket for fishing tackle 1.
Embodiments of the guide ring holder for fishing tackle and the method for manufacturing the guide ring holder for fishing tackle of the present invention have been described above, but these embodiments are presented as examples and are not intended to limit the scope of the present invention. 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 a fixed fiber length may be used. That is, any fiber-reinforced resin may be used as long as it contains reinforcing fibers having at least irregular directions.
In the above embodiment, the bent portion W of the stent body 10 is configured to include the first bent portion Wa of the ring holding portion 11 and the second bent portion Wb located at the boundary portion between the ring holding portion 11 and the support leg portion 12, but the position of the bent portion W is not limited to these positions, and the bent portion W formed at another position of the stent body 10 is also an application object of the present invention. The curved portion W is not limited to a curved surface having one radius of curvature as in the above embodiment.
Further, although the guide ring stay 1 for a fishing tackle according to the present embodiment includes the stay body 10 and the reinforcing rib 20, a guide ring stay 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 rib are not limited to the specific configurations described above.
