Description

The present invention relates to a fishing rod, and more particularly to a fishing rod having a parallel structure and a feature of a lower plug portion, and a lower plug fixed to an opening at a base end of such a fishing rod.

Conventionally, parallel type fishing rods have been known, and in particular, in a type of fishing rod that does not have a reel (also referred to as a Nobe rod), a small diameter rod rod is stored in a large diameter rod rod and carried. Specifically, a plurality of middle rods (2nd, 3rd, 4th, etc.) are sequentially joined to the tip of the original rod (also called the 1st section), and the tip of the tip is connected to the middle rod at the tip. In the parallel fishing rod where the rod rods are joined, the 3rd section, 5th section, etc. are stored in the 1st section, and the 4th section, 6th section, etc. are stored in the 2nd section in order. However, it is carried in two states (1st and 2nd sections).

Usually, in a fishing rod as described above, a lower plug (also referred to as a butt plug) is press-fitted and fixed to the base end opening of the original rod rod. The lower plug is a flexible material such as rubber or EVA so as to protect the original rod rod and the inner rod rod to be stored, for example, as disclosed in Patent Documents 1 and 2. Alternatively, it is made of a hard material such as ABS or metal. When the lower plug is formed of a hard material, a cushioning relaxation member such as a plate-shaped rubber is adhered to the bottom of the inner surface so as to cushion the impact even if the inner rod is in contact with the rod. Further, such a lower plug is press-fitted from the opening at the base end of the original rod and adhered, but an enlarged diameter portion is formed at the rear end so as to protect the opening edge of the original rod. The open edge of the original rod is attached. Such an enlarged diameter portion enhances the sense of unity with the original rod rod, reduces the burden when carrying, improves operability, and reduces the weight, so that the curved surface shape (dome) with less protrusion in the axial direction is achieved. Shape).

By the way, when the above-mentioned fishing rod is used in a place where the ground is uneven such as a mountain stream, a rocky place, or a sandbox, if the fishing rod is placed in an upright state, the rod rod and the ground will collide with each other and be damaged. May be attached. In particular, the conventional lower plug is designed to reduce the weight by shortening the amount of protrusion from the opening edge of the main rod, so that the distance between the main rod and the ground is short and it is easily scratched. Further, when the lower plug is made of metal or a hard material, as described above, it is necessary to attach a flexible member (such as rubber plate) to the inner surface bottom in order to cushion the impact. , Flexible members may peel off. Further, although the design can be improved by forming the lower plug with a metal material, electrolytic corrosion occurs between the lower plug and the rod rod.

The present invention has been made by paying attention to the above-mentioned problems, and an object of the present invention is to provide a fishing rod and a lower plug in which the original rod rod is less likely to be scratched or damaged.

In order to achieve the above object, in the fishing rod according to the present invention, a plurality of rod rods are joined in parallel, and a lower plug is fixed to the base end portion of the original rod rod. A fixed portion that is integrally formed of a flexible material and is press-fitted and fixed to the inner surface of the base end opening of the original rod, and a protrusion that protrudes in the axial direction while being press-fitted and fixed to the base end opening. It has a portion and an annular cap member attached to the peripheral surface of the protruding portion and formed of a hard material, and an opening of the original rod rod is provided between the fixed portion and the protruding portion. It is characterized in that a ring-shaped rib is formed in which the end edge and the open end edge of the cap member are abutted and fixed from both sides in the axial direction.

In the fishing rod having the above configuration, since the lower plug is made of a flexible member, it is possible to reduce the impact on the rod rod stored without attaching another member, and the protruding portion of the lower plug. Since a hard cap member is attached to the rod, it is possible to prevent damage to the original rod rod. In addition, since the lower plug is formed with ring-shaped ribs so that the open end edge of the original rod rod and the open end edge of the cap member come into contact with each other from both sides, even if the hard member hits another object, an impact will occur. It is difficult to convey to the original rod, and it is possible to prevent it from being damaged. Furthermore, by securing the length (height) of the protruding part, it is possible to increase the distance to the original rod rod when leaning against the uneven surface of the ground, and it is possible to protect the material of the original rod rod. It becomes.

Further, in order to achieve the above object, the lower plug according to the present invention is press-fitted and fixed to the base end portion of a parallel fishing rod, and is integrally formed in a columnar shape with a flexible material. The middle part of the main body of the lower plug is fixed by abutting the open end edge of the base end of the original rod from one end side, and is formed of a hard material to be press-fitted from the other end side. It is characterized in that a ring-shaped rib is formed so that the open end edge of the annular cap member is abutted and fixed.

The lower plug having the above-mentioned shape is press-fitted from the base end opening of the main rod of the parallel fishing rod (nobe rod) and fixed by adhesion. When the lower plug is fixed, a ring-shaped rib is interposed between the annular cap member and the original rod rod, so that the same action and effect as the above-mentioned fishing rod can be obtained.

According to the present invention, it is possible to obtain a fishing rod and a lower plug in which the original rod rod is less likely to be scratched or damaged.

It is a figure which shows one Embodiment of the fishing rod which concerns on this invention, and is the figure which shows the part of the original rod rod. It is a figure which shows the lower plug, (a) is an exploded view, (b) is a figure which shows the state which attached the cap member. (A) to (c) are diagrams showing various deformation examples of the main body of the lower plug.

1 and 2 are views showing an embodiment of a fishing rod and a lower plug according to the present invention, FIG. 1 is a view showing a portion of a main rod rod, and FIG. 2 is a view showing a lower plug (a). ) Is an exploded view, and (b) is a view showing a state in which the cap member is attached.

The fishing rod (nobe rod) according to the present invention is configured by a known parallel splicing type in which a plurality of rod rods are sequentially spliced, and FIG. 1 shows a main rod among a plurality of spliced rod rods. The part of the rod 1 is shown. As mentioned above, the parallel type fishing rod stores the 3rd, 5th, etc. inside the original rod (1st section), and the 4th, 6th, etc. in the 2nd section. It is stored and carried in two states (1st and 2nd sections), and the lower plug 10 is press-fitted into the base end portion (base end opening) of the original rod 1 and adhered or the like. It is fixed. In this case, the lower plug 10 may be fixed only by press-fitting without using an adhesive.

As is known, the above-mentioned original rod 1 is configured as a tubular body made of fiber-reinforced resin. For example, reinforcing fibers (mainly carbon fibers, glass fibers, etc.) are impregnated with a synthetic resin such as an epoxy resin. The fiber-reinforced resin prepreg sheet is wound around a core metal (mandrel), subjected to a heating process, and then decentered, and is formed according to a conventional method. It is possible to form other rod rods sequentially joined to the original rod rod 1 in the same manner.

A lower plug 10 is fitted into the base end opening 1a of the original rod 1 and adhered to the inner peripheral surface thereof. Hereinafter, the configuration of the lower plug will be described.
The lower plug 10 is integrally formed of a flexible material in a columnar shape, and the main body 10A of the lower plug 10 is fixed (adhered) by press-fitting into the inner surface of the base end opening 1a of the original rod 1. And a protruding portion 12 that protrudes in the axial direction in a state of being press-fitted and fixed to the base end opening 1a.

The material constituting the lower plug 10 (main body 10A) may have flexibility (cushion) itself, and is formed of, for example, rubber (natural rubber or various synthetic rubbers), foamed resin member, cork, or the like. It is possible, and in consideration of lightness, flexibility (cushioning property), durability, etc., it is preferably formed of a foamed resin member. In this case, as the foamed resin member, for example, EVA (ethylene / vinyl acetate copolymer resin), polystyrene, polypropylene, polyurethane, polyethylene or the like can be used. Further, when the above-mentioned rubber is used as the constituent material of the lower plug, the specific gravity is high and the weight is also heavy. Therefore, it is preferable to use a foamed resin member having a lower specific gravity than rubber as the constituent material (particularly, rubber). It is preferable to use EVA in consideration of the fact that the adhesive is more easily peeled off than EVA). Specifically, those having a specific gravity of 0.15 to 0.50, preferably those having a specific gravity of about 0.20 to 0.40 are preferably used. As for the hardness, if it is too soft, deformation or cracking is likely to occur, and if it is too hard, deformation or the like is unlikely to occur, but the impact mitigation effect is diminished. Therefore, a hardness of 50 ° to 90 ° is used. It is preferable (measured with the Asker C type rubber hardness tester adopted in JIS K 7312).

An annular cap member 15 made of a hard material is adhered and fixed to the peripheral surface of the protruding portion 12. Since the cap member 15 is formed in a cylindrical shape with one side open and the inside is lightened, the weight can be reduced. For example, the cap member 15 can be integrally formed of a hard resin or metal (for example). Considering the design, it is preferably formed of metal). In particular, when it is formed of a metal material, it is preferable to use a lightweight metal having a specific gravity of 3 or less, such as aluminum metal (including an aluminum alloy) and magnesium. Such a cap member 15 can be press-fitted and fixed (adhered) to the protruding portion 12 in advance, and in this state, the fixing portion 11 can be press-fitted and fixed to the base end opening 1a of the main rod. can.

At an intermediate position between the fixed portion 11 and the protruding portion 12 of the main body 10A, the open end edge 1b of the original rod 1 is attached from one end side, and the open end edge 15a of the cap member 15 is attached from the other end side. The ring-shaped rib 18 to be fixed is integrally formed. For the rib 18, the lower plug 10 is formed at the base end of the main rod rod by forming the amount of bulge in the radial direction to be substantially the same as the wall thickness of the main rod rod 1 and the wall thickness of the cap member 18. When press-fitted and fixed to the portion opening 1a, the outer surface of the cap member can be flushed from the original rod rod. That is, since the rib 18 portion does not protrude in the radial direction or form a circumferential groove, it is possible to prevent damage to the tail plug (rib) and adhesion of foreign matter.

The protruding portion 12 can be formed to have a certain height so that the distance from the unevenness of the ground to the original rod rod becomes long when the fishing rod is leaned against the ground. That is, by forming the main body 10A from a material having a relatively low specific gravity and attaching a lightened (thin wall thickness) cap member 15, the weight can be reduced as a whole, so that the protruding portion 12 protrudes. It is possible to increase the amount. Specifically, by securing a length L of the protruding portion 12 of 12 mm or more, it is possible to secure a sufficient amount of escape from the original rod rod from unevenness such as sandboxes and rocks even when the fishing rod is leaned against it. It is possible to prevent the original rod rod from being scratched. However, if it is made too long, the rear end of the fishing rod becomes heavy, so it is preferably 25 mm or less.

The lower plug 10 having the above configuration is bonded by forming protrusions or grooves (recesses) in the region where bonding (press fitting) is performed, that is, on the outer peripheral surface of at least one of the fixing portion 11 and the protruding portion 12. The strength can be improved. For example, a spiral groove 11a (see FIG. 3A), a plurality of circumferential grooves 11b (see FIG. 3B), or a large number of recesses with respect to the outer peripheral surface of the fixing portion 11. By forming 11c (see FIG. 3C), the adhesive can enter and the anchor effect can be enhanced, and the adhesive strength can be improved. Further, in addition to the groove (concave portion) having the shape shown in FIG. 3, a convex portion, a protrusion or the like (arbitrary shape) may be formed, or a structure combining these may be formed, or simply the surface may be formed. It may have a roughened structure. Further, similar grooves, concave portions, convex portions, and protrusions may be formed on the protruding portion 12 side. A groove, a convex portion, or the like may be formed on the bottom surface 11A of the fixing portion 11 (the bottom surface when the lower plug 10 is fixed to the original rod rod), but the base end portion of the inserted small-diameter rod rod. Therefore, it is not necessary to form it in consideration of shock absorption. Alternatively, the adhesive strength can be improved by forming a groove, a convex portion, or the like on the inner peripheral surface of the cap member 15.

According to the fishing rod and the lower plug having the above-described configuration, since the main body 10A of the lower plug 10 is formed of a flexible member, the impact mitigation effect is enhanced and the rod rod can be protected. Further, since it is not necessary to separately attach an elastic member such as rubber to the inner bottom to which the base end of the small-diameter rod rod is attached, the rubber member does not come off. Further, since the portion that comes into contact with other objects is the cap member 15 that is a hard material (hard resin or metal), damage to the lower plug itself can be prevented. In particular, by increasing the amount of protrusion of the protruding portion 12, it is possible to secure the amount of escape of the original rod 1 from the ground and effectively prevent the original rod 1 from being damaged. Further, by forming the protruding portion 12, even if the cap member 15 is made of metal, the inside can be hollowed out, so that the weight can be reduced.

Further, since the rib 18 formed on the main body 10A of the lower plug is interposed between the open end edge 1b of the main rod and the open end edge 15a of the cap member 15, the impact received by the cap member 15 is alleviated. Can protect the original rod. Further, when the cap member 15 is made of a metal material, the ring-shaped ribs 18 are interposed, so that electrolytic corrosion occurring between the two can be prevented. Further, since the rib 18 is integrally formed with the main body 10A and is flexible, even if the open end edge 1b of the molded original rod 1 is cut diagonally, when the lower plug 10 is adhered and fixed, the rib 18 is formed. Since the gap is filled by the opening edge 1b hitting the rib 18, the gap generated by cutting diagonally can be made inconspicuous.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be variously modified.
For example, it is possible to prevent deformation of the main body by fitting a pin such as tapered aluminum into the center of the main body 10A of the lower plug, and to increase the diameter and fix it to the main rod 2 by press fitting. You can also do it. Further, the main body 10A may be partially lightened, and the cap member 15 may be appropriately decorated on the outside such as forming a groove 15b on the outer peripheral surface. Further, the lower plug having the above-described structure may be fixed to the opening at the base end of the second section of the fishing rod.
