Description
【発明の詳細な説明】 産業上の利用分野 本発明の穂先釣竿の改良に関するものである。[Detailed description of the invention] Industrial applications The present invention relates to an improvement of the tip fishing rod of the present invention.

−21863号公報等で知られているが、曲げ強度に
対する折損を充分に防止できないのが実状であ
る。Conventional technology In order to improve the strength of solid-tip rods, it was first developed in 1983 that reinforcing threads were integrally wound around the twill thread around the circumference.
Although it is known from Japanese Patent No.-21863, etc., the actual situation is that breakage cannot be sufficiently prevented due to bending strength.

のでテーパー面においては引揃繊維同士がささく
れ状に剥離し易く、その外周面に補強糸条を綾巻
条に捲着しても折損を充分に防止することができ
ない。 In other words, the reinforcing fibers that make up the solid tip rod are formed by cutting aligned fibers into a tapered shape, so on the tapered surface, the aligned fibers tend to peel off like hangnails, and reinforcing is applied to the outer peripheral surface. Even if the thread is wound in a twill pattern, breakage cannot be sufficiently prevented.
これを防止するために補強糸条を密接捲着して
補強すると、穂先の調子を崩すと共に重量も増加
し張りもなくなる欠陥がある。 In order to prevent this, if reinforcing threads are tightly wrapped around the reinforcing yarn, the condition of the tip will be disturbed, the weight will increase, and there will be no tension.

る。Problems to be Solved by the Invention In view of the current situation, the present inventor has conducted various experimental studies on the type of reinforcing yarn, the winding interval, and the winding angle. By using a reinforcing yarn with a low ratio and low tensile strength and by specifying the relationship between the winding interval and the winding angle, the bending strength of the tip rod can be significantly increased. The purpose of this is to increase the bending strength without impairing the condition of the rod by the reinforcing yarn wound around it.

するものである。Means for Solving the Problems As a means for achieving the above object, the present invention jointly fixes a hollow rod to the rear part of a solid rod, and a reinforcing thread is attached from each joint to the tip of the solid rod. In a tip rod in which the rods are integrally wound in a twill shape, the reinforcing fibers of the solid rod rod are carbon aligned fibers, and the reinforcing threads have lower elastic modulus and tensile strength than the carbon aligned fibers. The winding angle with respect to the axis of the reinforcing yarn is gradually increased from 15 to 40 degrees from the tip to the rear end, and the winding interval is 3 to 5 mm. The main points are as follows.

着目し次の実験を行つた。 The present inventor uses fibers having a lower elastic modulus and lower tensile strength than the carbon aligned fibers as the reinforcing yarn to be cross-wound around a solid tip rod made of carbon aligned fibers, and the reinforcing yarn to be cross-wound. The following experiment was conducted focusing on the relationship between the winding angle and the winding interval with respect to the axis of the strip.

した結果は第４図のとおりである。 A 480 mm solid rod made by impregnating and curing modified epoxy resin into carbon aligned fibers (tensile strength 360 Kg/mm 2 , elastic modulus 23500 Kg/mm 2 ), and carbon aligned fibers (tensile strength 350 Kg/mm 2 , Elastic modulus 30000Kg/ mm2 )
A solid rod made by impregnating and hardening a modified epoxy resin was joined together to create a rod with a total length of 1100 mm, a tip diameter of 0.63 mm, and a rear end diameter of 4.47 mm, and aramid fiber ( A 195 denier reinforcing yarn bundle with a tensile strength of 138 Kg/mm 2 and an elastic modulus of 750 to 8000 Kg/mm 2 was wound in sequence so that the winding angle with respect to the axis was 1 to 9 degrees from the tip to the rear end. The conventional tip is wound integrally in a twill shape with a winding interval of 8 mm, and the same reinforcing yarn is wound at a winding angle of 15 to 35 degrees from the tip to the rear end. When the tips are wound in a twill pattern with a winding interval of 4 mm, fishing line is tied to each tip of the tip as shown in Figure 3, and the fishing line is pulled, the breakage load of each of the five tips ( Figure 4 shows the measurement results of the fishing line (Kg) and the tensile length (mm) at the time of breakage of the fishing line.

た。 As is clear from these results, it was confirmed that the bending strength of the tip rod formed by increasing the winding angle of the twilled thread and making the winding interval small can significantly increase the bending strength without impairing its condition. .
