BACKGROUND OF THE INVENTION
The present invention relates to a small-diameter point rod positioned closest to the tip of a fishing rod formed by connecting a plurality of rods.
[0002]
[Prior art]
In general, a fishing rod used for fishing is a single fishing rod that is formed by connecting a plurality of rods with a plurality of tapered tapers. Each housing is a hollow cylindrical member made of a prepreg material in which reinforcing fibers such as carbon fibers and glass fibers are aligned and impregnated with a synthetic resin such as an epoxy resin. Each rod is taper-tapered, and even as individual rods, the main rod located on the most heel side has the largest diameter, and the rods located on the tip side gradually decrease in diameter. It has become.
[0003]
Each frame made of such a predetermined material is lightweight and has sufficient flexibility, enabling a smooth fishing operation. Among these rods, the tip bud located on the most tip side has a sufficiently small diameter to react sharply to the bite of the fish when the fish is applied to the mechanism, especially, On the tip side, a sufficiently small diameter is achieved.
[0004]
[Problems to be solved by the invention]
As described above, the tip rod is currently sufficiently small in diameter, but the tip rod is located at the tip end of the tip of the fishing rod, so there are many opportunities to come in contact with obstacles, and in particular, a hollow cylindrical body Often, the tip of the head is broken and damaged. For this reason, there is a fishing rod using a solid tip rod in order to improve the physical strength while maintaining the flexibility by sufficiently reducing the diameter.
[0005]
However, the head with the entire head is solid, which leads to a relatively heavy weight. In addition, it is possible to improve the strength by increasing the thickness of only the tip side portion of the hollow tip, but it is cumbersome to form a small-diameter frame by providing a partial change in thickness, etc. There is a high cost.
[0006]
An object of the present invention is to provide a spikelet which is not easily damaged and can be sufficiently reduced in weight.
[0007]
[Means for Solving the Problems]

In this spikelet, a solid rod-like body is separately inserted inside the tip of the hollow cylindrical body, and a part of the cylindrical body on the tip side is partially solid. A rod-shaped body reinforces the end of the tip of the tip of the tip that touches an obstacle or the like and is easily damaged, and prevents the damage. In addition, the tip end is made of a hollow cylindrical body other than the end portion on the tip end side, and unnecessary weight increase does not occur.
[0009]
Furthermore, such a spike can be easily processed by forming a hollow cylindrical body according to a predetermined manufacturing method and then inserting and fixing a separately formed rod-shaped body, making production easy and economical. It will be excellent.
[0010]
The spikelet of the invention 2 is the spikelet of the invention 1, and the rod-shaped body is arranged in the range of the axial length of 5 to 20 cm from the tip side end portion of the cylindrical body.
[0011]
A rod-shaped body reinforces a predetermined range from the end part on the tip side of the cylindrical body, and prevents damage to the end part on the tip side of the tip part.
[0012]
The spikelet of the invention 3 is the spikelet of the invention 1 or 2, and the rod-shaped body is made of a prepreg material in which reinforcing fibers are oriented in the axial direction and impregnated with a synthetic resin.
[0013]
This rod-shaped body is made of a prepreg material in which reinforcing fibers are oriented in the axial direction, and sufficiently improves the bending rigidity in the axial direction of the end side of the tip of the tip of the tip to prevent breakage.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0015]
As shown in FIG. 1, the fishing rod employing the first embodiment of the present invention includes a tubular harpoon 1, a former harpoon 2, and a middle harpoon 3 that are sequentially connected to the tip side of the harpoon 1. . And the fixed guide 5 is mounted | worn with the peripheral part of the edge part by the side of the tip of the upper collar 2 and the middle collar 3, and a plurality of slides are slidable on the circumferential surface in the axial direction on the circumferential surface of the collar A guide 6 is arranged. Further, a top guide 7 is fixed to the end of the tip end 4 of the tip end 4 and a slide guide 6 is disposed on the periphery of the end of the tip end so as to be slidable on the peripheral surface in the axial direction. Each slide guide 6 moves in the axial direction on each casing circumferential surface, and is fixed at a predetermined axial position on the casing circumferential surface by matching the inner diameter with the outer diameter of the casing.
[0016]
The base rod 1 to the center rod 3 are cylindrical members each having a tapered taper formed from a prepreg made of carbon fiber reinforced resin, glass fiber reinforced resin, or the like. Sequentially, it is possible to fit and fix the heel-side end of the casing connected to the tip side on the inner peripheral surface of the tip-side end (this is a so-called swing-out type). A reel sheet 8 for detachably mounting a reel (not shown) is integrally disposed on the peripheral surface of the main rod 1, and a butt plug is also mounted on the end of the flange side.
[0017]
As shown in FIG. 2, the tip 4 has a tubular body 10 and a rod-like body 11 disposed in the end part on the tip side of the tubular body 10. The cylindrical body 10 is a tapered member made of a carbon fiber reinforced resin, a glass fiber reinforced resin, or the like, similar to the above-described base 1 or the like. The heel side end portion is a fitting male portion, which is fitted to the inner peripheral surface of the tip side end portion of the middle collar 3 and can be connected to the tip side of the middle collar 3 in a swinging manner.
[0018]
As a prepreg material such as a carbon fiber reinforced resin constituting the tubular body 10, a material processed into a plurality of sheets or tapes can be used. The cylindrical body 10 is manufactured by firing these in a furnace. Specifically, the tubular body 10 is manufactured by laminating a prepreg material in which reinforcing fibers are aligned in the axial direction on the outer periphery of the core material, a prepreg material aligned in the circumferential direction, and the like in a timely combination and firing. ing.
[0019]
The rod-shaped body 11 is a solid rod-shaped body formed using a material similar to the prepreg material constituting the above-described tubular body 10 or formed from a synthetic resin material that does not include reinforcing fibers. It is set so as to match the inner diameter of the end portion on the tip side of the cylindrical body 10, and is inserted into the inside from the base side of the cylindrical body 10, and is fixed with, for example, an adhesive. Specifically, this rod-shaped body 11 is manufactured by, for example, winding and firing a prepreg material processed into a sheet shape into a rod shape, or by extrusion molding or insert molding. When the rod-shaped body 11 is made of a fiber reinforced resin, the reinforcing fibers are preferably oriented in the axial direction.
[0020]
The axial length of the rod-shaped body 11 is set in accordance with the axial length of the tip ridge 4, but has an axial length of about 5 to 15 cm from the end on the tip side. Is preferred. In particular, this is the range where there is a high risk of damage due to contact with obstacles.
[0021]
In addition, in order to use as an adhesive reservoir when bonding and fixing to the cylindrical body 10, a plurality of axial and / or circumferential grooves may be formed on the outer peripheral surface of the rod-shaped body 11 (see FIG. 3). It is sufficient that such a groove is formed by cutting the peripheral surface after manufacturing the rod-shaped body 11.
