Description

[Detailed description of the invention] [Industrial application field] The invention relates to a swing fishing rod that can draw out a middle rod pipe and a front rod pipe from a former rod pipe and store and lock them so that they can be joined.

(Prior art)

Conventionally, a swing fishing rod generally divides the entire length of the fishing rod into a plurality of pieces, and arranges a plurality of middle rod pipes concentrically outside the leading rod pipe,
These middle rod pipes are housed in a former rod pipe. Various measures have been taken on the swing fishing rod in order to prevent rattling when the middle rod pipe is stored in the original rod pipe. As such a swing fishing rod, for example,
No.-2938, a proposal to fix an annular part to the rod end as in Japanese Utility Model Publication No. 56-57072, a proposal to fit an annular projection into the clearance between the rod pipes as in Japanese Utility Model Publication No. 44-19580, Japanese Patent Application Laid-Open No. Sho 59-125831 discloses a proposal in which a rod-shaped inner diameter is fitted to a column-shaped mountain-shaped projection.

[Problem to be Solved by the Invention] In the case of using an annular part as described above, if a large number of middle rod pipes are housed in the original rod pipe, the clearance between the rod pipes is small, so it is practically difficult in dimensions. However, there are disadvantages that the structure becomes complicated and large, the ring-shaped parts cannot be fixed by bonding, and the durability is poor.

Also, in the above proposal, the annular projection is difficult to fit in the clearance between the rod pipes, the rod pipe is hard to fit in the cylindrical projection having a large surface area, and the angled projection has a long closed dimension when the angle is acute, and the angle is small. When the angle is obtuse, there is a disadvantage that the locking of the rod tube becomes insufficient.

SUMMARY OF THE INVENTION An object of the present invention is to propose a swing fishing rod in which a protruding portion is formed at the base of a rod tube so that even if the clearance between the rod tubes is small, it can be easily and securely locked.

[Means for solving the problem]

In view of the above object, in the present invention, the outer diameter of the original portion of the rod pipe to be drawn is smaller than the inner diameter of the rod pipe being drawn out from the adjacent outer rod pipe, and is smaller than the inner diameter of the joint of the outer rod pipe tip. A swing fishing rod that is large, and one or more middle rod pipes and a front rod pipe are drawn out into a former rod pipe and stowable and stored.
The rod end part provided at the rod end of the original rod pipe is a form of the original part of the original rod pipe, and between the original parts of adjacent rod pipes excluding the leading rod pipe,
At least one of the adjacent inner or outer circumferences has a protruding portion formed on a part thereof, and the protruding portion is pressed into the other and locked by deformation of a cross-sectional shape. The gist of the present invention is to provide at least one or more internal and external combinations.

Therefore, there are a swing fishing rod in which rod pipes are locked, a swing fishing rod in which a middle rod pipe and a rod bottom part are locked, and a swing fishing rod in which these are mixed. For example, there are eight middle rod pipes,
Of these, the first inner rod pipe adjacent to the former rod pipe, the next second inner rod pipe, and the next third inner rod pipe, a total of three adjacent inner rod pipes, are the former rod pipe, the first and second inner rod pipes. The second middle rod pipe may be locked, and the other middle rod pipe and the leading rod pipe may not be locked.

FIG. 3 is an end view of FIG. 2 in which an enlarged sectional side view of a main part is hatched so that each rod pipe can be easily distinguished. In FIG. 1, a plurality of middle rod pipes 2, 3, 4 and a front rod pipe 5
Are stored so that they can be pulled out and joined. A rod end fitting 6 as a component of a rod end part is fixed to the outer periphery of the base portion of the main rod 1, and an elastic body 7 is fitted inside the rod end fitting 6. The rod end fitting 6 includes a cylindrical fitting 8 and a bottom fitting 9, and the bottom fitting 9 is screwed to the cylindrical fitting 8.

The original rod pipe 1 and each of the middle rod pipes 2, 3, and 4 are made of woven cloth reinforced with carbon fiber, glass fiber, aramid fiber, alumina fiber, Kepler fiber, and other high-strength fibers such as organic fibers and inorganic fibers. After a prepreg sheet impregnated with a thermosetting synthetic resin such as an epoxy resin, a phenol resin, or a polyester resin is wound around a core metal (not shown) a suitable number of times, the outside thereof is taped and placed in a heating furnace. It is formed integrally by thermosetting according to a conventional method. The front rod pipe 5 is also formed of the same material as the original rod pipe 1 and each of the middle rod pipes 2, 3, and 4.
