Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a through fishing rod.

[0002]

2. Description of the Related Art From the viewpoint of improving the slipperiness of a fishing line and preventing frictional damage on the inner peripheral surface of a rod tube, it is known to mount a fishing line guide inside the rod tube, for example, in Japanese Patent Application Laid-Open No. Sho 56-127032 and Japanese Utility Model Application Laid-Open No. Sho 63-163. -129466.

[0003]

However, if the entangled or knotted fishing line breaks while being hooked on the fishing line guide inside the rod tube, the hooked line is removed because it is inside the rod tube. It is difficult. Further, if the knotted fishing line is pulled out from the rod pipe by a throwing operation or as it is to release the hooked state, the rod pipe may be damaged by an excessive force at that time.

Accordingly, an object of the present invention is to prevent a tangled or knotted fishing line from damaging the rod tube when the fishing line attempts to pass through the inside of the rod tube.

[0005]

DISCLOSURE OF THE INVENTION In view of the above object, the present invention provides a rod pipe formed by winding a prepreg in which high-strength fiber is impregnated or mixed with a resin, and a rod having a joint having an outer portion and Divided into the thinnest tip portion and the middle portion thereof, wherein the thickness of the tip portion is thicker than the thickness of the middle portion, and the ratio of the circumferential fibers in the fibers constituting the tip portion is the middle portion. A through fishing rod characterized by having a ratio greater than a ratio of a circumferential fiber to a fiber constituting a portion.

[0006] The rod tube is usually torn at the thinnest tip when the knotted fishing line is inserted, but this portion is formed thicker than the middle portion, and the ratio of circumferential fibers is large. The tip is more resistant to longitudinal tearing.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail based on an embodiment shown in the accompanying drawings. FIG. 1 shows an embodiment of a fishing rod according to the present invention. High-strength fiber such as carbon is impregnated with a thermosetting resin such as epoxy resin, or a fiber-reinforced prepreg (used in a broad sense including thermoplastic resin) mixed with thermoplastic resin such as polyamide is wound and fired. Former rod 10, middle rod 12, using molded rod tube,
The inside fishing rod composed of the tip rod 14 is shown.

[0008] A reel sheet 18 is attached to the original rod 10, and a reel 20 is attached to this. A fishing line introduction part 22 for introducing a fishing line 24 therein is provided in front of it. A top guide 16 is attached to the tip of the tip rod 14.

FIG. 2 is a longitudinal sectional view of the tip rod 14. As shown in FIG. The tip rod 14 has an original part 14A having a spliced part 14a which is originally thickened and reinforced with a thick rod pipe, and a small tapered tip part 14C having the thinnest outer diameter. An intermediate portion between them is considered as being divided into an intermediate portion 14B having a taper slightly larger than the tip portion 14C.

A fishing line guide G1 such as an annular ceramic is held at a rear end of the base portion 14A by a holding body H1 and screwed thereto. A top guide 16 is attached to the tip of the tip 14C, and a tip guide G6 is fixed to the inner periphery of the tip. Inside the tip, a tip guide G5 is located at the tip of the tip 14C. Installed. When a fishing line having a knot-shaped portion is inserted through the tip rod 14, it may be stopped outside the front and rear guides G1 and G5, but if it passes inside, the inner diameter of the tip rod 14 In some cases, the tip rod 14 may be broken vertically.

That is, the inner diameter of the tip portion 14C is equal to the fishing line guide G1.
If the inner diameter of the fishing line is smaller than the inner diameter of the fishing line, the fishing line having the knot-shaped portion passing therethrough may tear the fishing line. Therefore, when the fishing line guide G1 is attached to the rear end of the tip rod 14,
It is preferable that the reinforcing layer 14CH described later of 4C be formed in a portion where the inner diameter of the tip portion 14C is less than or equal to the inner diameter of the fishing line guide G1, since the influence on the bending characteristics of the tip rod 14 can be minimized.

In the present invention, the tip 14C having the smallest outer diameter is used.
The reinforcement layer 14CH having a high fiber ratio in the circumferential direction is integrally formed on the inner periphery of the tip 14C in order to reinforce. As a result, the thickness is larger than that of the intermediate portion 14B, and the ratio of the fibers in the circumferential direction is larger than that of the intermediate portion 14B. For this reason, the strength of the tip portion 14C against vertical cracks (tear) is improved, and the risk of the rod tube being torn when a fishing line having a knot-shaped portion is inserted is reduced.

The reinforcing layer 14CH is preferably formed only on the front portion 14C and formed as the innermost layer, but may be formed on the outer layer or the middle layer. As the circumferential fibers of the reinforcing layer 14CH, it is preferable to use reinforcing fibers having a smaller elongation at break than the fibers or resin of the main body layer (the ratio of elongation before the fibers are broken, that is, hard to elongate). In addition to normal aligned fibers, a bag net formed by knitting fibers in a bag net shape from the front-back direction of the tip 14C may be used. By setting the fiber direction at an angle of about 30 to 60 degrees, circumferential reinforcement can be achieved. Further, a thread may be wound around the outer periphery of the tip portion 14C and reinforced.

As the reinforcing fiber for reinforcement, a fiber having water repellency or a fiber having abrasion resistance is preferably used. For example, techmilon fiber (trade name), ceramic fiber, metal fiber, and the like. The thickness of the reinforced tip portion 14C is 1.
It is preferable to set about 2 to 2 times.

[0015]

As is apparent from the above description, according to the present invention, the risk that the entangled or knotted fishing line will break the rod tube when trying to pass through the inside of the rod tube can be reduced. .
