Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hollow fishing rod in which a fishing line introducing hole is formed on the outer surface of a fishing rod and a fishing line feeding path is formed inside the fishing rod.

[0002]

2. Description of the Related Art Conventionally, as a fishing rod, it has been used as a conventional fishing rod.
There is one disclosed in Japanese Patent No. 9655, and in this one, a thread introduction hole is formed in a base rod on which a reel is mounted.

[0003]

Therefore, in the above construction, even when the fishing line is handled without fishing, the thread introducing hole is exposed, so that it is easy to damage the introducing hole with another object. If the scratched part comes into contact with the thread, it will damage the thread and create a factor of thread breakage.Therefore, it is necessary to take some measures to cover that part, and the thread introduction hole must be in the same position. Therefore, it is necessary to handle the fishing rod in a long state even when moving the fishing ground. Therefore, an object of the present invention is to allow the position of the thread introduction hole formed above to be switched to the original rod at the time of a fishing operation and at the time of moving a fishing place, respectively, so that the position can be changed at the time of fishing. Is to provide a hollow fishing rod that can reduce the fishing-out resistance of the fishing line and can make the fishing rod compact when moving in the fishing area.

[0004]

In order to solve the above-mentioned problems, the threading rod according to the present invention is more effective than the first hand side rod member with respect to the first hand side rod member having the reel seat at the intermediate position. Also, the second rod rod member having a small diameter is accommodated in a stretchable manner, and a threading hole for introducing a fishing line into the inside is formed on the outer surface of the second rod member rod. A first position holding for fixing the second hand side rod material in an extended state pulled out from the first hand side rod material so that the introduction hole is located in front of the front end of the first hand side rod material. And the second hand-side rod member so that the yarn introducing hole is located in front of the front end of the first hand-side rod member and close to the front end of the first hand-side rod member. Second position holding means for fixing in a first contracted state in which it contracts with respect to the hand side rod material. When actually performing a fishing operation, the second rod member on the proximal side is pulled out and set in an extended state, and the distance between the thread introducing hole and the reel is set to be large, and The degree of refraction of the fishing line is reduced to reduce the payout resistance of the line. Then, when moving the fishing ground, with the thread positioned in the second proximal rod material, the second proximal rod material is positioned in the contracted state, and the thread introduction hole is placed in the first proximal rod material. By setting it at a position closer to the front end of the first proximal rod member on the front side than the front end of the member, the rod length can be shortened for carrying.

Further, the hollow rod according to the present invention is the second rod.
The thread introducing hole portion formed in the hand side rod material is provided with a thread introducing tool which projects from the outer peripheral surface of the second hand side rod material and guides the fishing line to the thread introducing hole. Since the fishing line from the reel is guided into the rod through the line introducing tool protruding from the outer peripheral surface of the second hand side rod material, the refraction degree of the fishing line in the line introducing hole is reduced, The feeding resistance can be further reduced.

Further, in the threading rod according to the present invention, the thread introducing tool is provided with a line intake port at a position projecting from an outer peripheral surface of the second proximal side rod member, and the fishing line is inserted from the line intake port into the rod. Is characterized in that an inclined guideway is formed to guide the fishing line from the reel to the inside of the rod through the inclined guideway from the line intake protruding from the outer peripheral surface of the second hand side rod material. Therefore, the degree of refraction of the fishing line in the line introduction hole can be reduced, and the line feeding resistance can be further reduced.

Furthermore, in the fishing rod according to the present invention, since the thread introducing tool is detachably attached to the thread introducing hole portion of the second hand side rod material, the fishing rod is finished and the fishing rod is removed. When storing in the closed state, the thread introducing tool is removed from the second proximal rod material, and the second proximal rod material is further moved to the first proximal side until the thread introducing hole is located in the first proximal rod material. It can be shrunk into the rod material to make it easy to carry.

Another embodiment of the present invention is as follows. Another embodiment of the present invention aims to provide a threading rod capable of preventing damage to the yarn introducing hole without providing a special mechanism, and its characteristic configuration is a first hand side having a reel sheet. This is the first for rod material
A second hand-side rod material having a diameter smaller than that of the hand-side rod material is retractably stored, and a fishing line introducing hole is formed on the outer surface of the second hand-side rod material. In a contracted state in which the second hand side rod material is contracted in the side rod material, the introduction hole is located inside the first hand side rod material, and the second hand side rod material is the first hand. The position holding means is formed so as to position the introduction hole forward and outward from the front end of the first hand side rod material in the stretched state pulled out from the side rod material. On the street. That is, since the thread introduction hole can be positioned inside the first proximal rod material in the contracted state, the thread introduction hole can be covered with the first proximal rod material and the contracted state is maintained. You can shorten the total length of the rod. Therefore, the first hand side rod material can also be used as a cover that covers the thread introduction hole, and the total length of the rod that has been stored can be shortened, which is convenient for carrying when traveling by car, etc. Doesn't require much space.

Further, in addition to the above-mentioned object, another embodiment of the present invention sets the thread in a convenient state for carrying it out while suppressing the thread feeding resistance and mounting the thread on the second hand side rod material. The purpose of the present invention is to provide a hollow rod that can be formed, and its characteristic configuration is that the rod material on the second hand side having a smaller diameter than the rod material on the first hand side having the reel seat is smaller than the rod material on the first hand side. In which the fishing line introducing hole is formed on the outer surface of the rod member on the second hand side, the introducing hole for the line is separated from the front end of the rod member on the first hand side. The thread introducing hole is located at the front side, and the thread introducing hole is located at the first state when the rod material on the second proximal side is pulled out from the rod material on the first proximal side. Proximity to the front end of the rod material on the first hand side, in front of the front end of the rod material on the hand side The second retracting side rod member so that the thread introducing hole is located in the first hand side rod member by the first contraction state in which the second contracting operation is performed and the second stage contraction operation. The position holding means is formed so as to be switchable to the second contracted state in which the rod material on the one hand side is stored further in the back side, and the function and effect thereof are as follows.

In other words, in the second contracted state, the thread introduction hole can be positioned inside the first proximal rod member and covered with the first proximal rod member, and the rod in the contracted state can be covered. The total length can be shortened. On the other hand, in the fishing ground, the thread introducing hole is located outside the front end of the first proximal rod member.
When actually performing a fishing operation in this state, the second hand side rod material is pulled out and set in the extended state, and the distance between the line introduction hole and the reel is set to be large so that the fishing line bends in the line introduction hole. The degree is reduced to reduce the yarn feeding resistance.
When moving the fishing ground, the second hand side rod material is placed in the first contracted state while the thread is placed in the second hand side rod material, and the thread introduction hole is moved to the first position. By setting it at a position closer to the front end of the rod member on the first hand side than the front end of the rod member on the hand side, the rod length can be shortened and carried. Therefore, in exhibitions at stores, etc., the thread introduction hole can also be covered by the first hand side rod material, and the total length of the rod can be shortened to reduce the space required for exhibition and expose the thread introduction hole. Even in this state, there is also a merit that the protruding state of the second proximal rod member can be switched according to the case of fishing such as fishing operation and movement of the fishing place.

In, in that the position holding portion is formed so as to be positioned at a position where the rear end opening of the core is brought close to the introduction hole,
The effect is as follows.

That is, the rear end opening of the core, through which the fishing line from the reel needs to be inserted next from the second proximal rod member, can be located near the line introduction hole in the first stored state. The rear end opening of the core can be visually observed through the thread introducing hole, and the thread inserted through the thread introducing hole can be inserted into the rear end opening. Therefore, in addition to the above effects, there is an advantage that the thread insertion work can be easily performed.
