Description

[Detailed Description of the Invention] Purpose of the Invention The present invention relates to a fishing rod and a method for manufacturing the same, and the present invention relates to a fishing rod and a method for manufacturing the same. The object of the present invention is to manufacture a fishing rod and the fishing rod which can sufficiently withstand the strength even when the reel mounting leg is directly attached to the rod tube.

Conventional technology The current method for attaching a reel to a fishing rod is to fit and fix a cylindrical reel seat onto the fishing rod, and to attach reel mounting legs between a fixed hood and a movable hood provided on the reel seat. However, since the angler's hand that grips the reel attachment part is gripping the reel seat and does not touch the rod tube directly, it is not possible to sensitively sense the fish (around the fish), it is difficult to grip, and it is difficult to use the reel for a long time. There are defects such as the reel sheet peeling off from the fishing rod during fishing.

Structure of the Invention The present invention improves the above-mentioned defects by integrally and continuously forming a built-up part, which is the second reel attachment part, and a male screw for tightening the moving hood on the rod pipe using the same material. be.

To explain an embodiment of the present invention with reference to the drawings, a rod tube 1 is constructed by impregnating reinforcing fibers such as glass fibers, carbon fibers, and aramid fibers with thermosetting synthetic resins such as epoxy resin and polyester resin. , a thick built-up part 2 and a male thread 3 are integrally formed with the same material as the rod tube 1 at the base end thereof. The fixed hood 4 is fixed, and a tightening ring 6 rotatably engaged with the movable hood 5 is screwed to the male screw 3 so that it can move forward and backward, so that there is a gap between the fixed hood 4 and the movable hood 5 in the built-up part 2. It is configured so that a reel mounting leg A can be attached thereto.

Therefore, the height of the male screw 3 is the same as the built-up part 2, and the height of the valley part is either slightly higher than the surface of the rod pipe 1 or is formed on the same surface as shown in FIG. It is preferable to
Moreover, the fixed hood 4, the movable hood 5, and the tightening ring 6 are made of metal.
It can be made of any material such as synthetic resin.

Next, to explain the manufacturing method of the fishing rod of the present invention, glass fiber,
A sheet or braided tube of prepreg 7 for rod tube construction, which is made by impregnating reinforcing fibers such as carbon fibers and aramid fibers with a thermosetting synthetic resin such as epoxy resin, polyester resin, and phenol resin, is wound or attached to the core bar 8. After that, a built-up prepreg 9 made of the same material as the rod tube component prepreg 7 is wrapped or coated on the base end, which is the reel attachment part, and polymerized. It is tied up with a shrinkable tube and heat-cured in the usual manner.

Next, after peeling and removing the tape 10 or the heat-shrinkable tube, the rear end of the built-up prepreg portion is ground with a gear grindstone, milling cutter 11, etc. until approximately one surface of the prepreg for rod tube construction is achieved. 3, and after pulling out the core bar 8, an annular fixed hood 4 is fixed to the front end of the built-up prepreg 9 portion by adhesive or other appropriate means, and a movable hood 5 is rotatably attached to the male screw 3. A fishing rod is manufactured by screwing together the tightening ring 6 that is engaged with the rod.

The prepreg 9 for overlaying is the prepreg 7 for configuring the rod pipe.
They do not necessarily have to be made of the same material, and may be made of the same material using different types of reinforcing fibers or different types of thermosetting synthetic resins.

Effects of the Invention In the present invention, a built-up part and a male screw are integrally formed of the same material on the reel attachment part of a rod pipe, and a tightening ring is provided to be screwed into a fixed hood fixed to the neck of the built-up part and the male screw. Since the reel mounting leg can be mounted directly on the rod tube between the moving hood, it is possible to reduce the weight of the fishing rod, and the palm of the hand gripping the rod is always in contact with the rod tube, making it easier to fish. It can be sensed directly and sensitively, making fishing operations light and easy.

In addition, the part where the reel mounting leg is attached is made thick by an integrated built-up part, so it is sufficient to withstand the localized concentrated load caused by the end of the reel mounting leg when the reel mounting leg is attached directly to the rod pipe. It can withstand damage such as cracking and distortion of the rod tube.

Moreover, unlike the conventional glue sheet adhesive method, it does not peel off due to temperature changes, impacts, repeated bending, etc. during long-term use.

In the present invention, overlay prepregs made of the same material are polymerized and bonded to the reel mounting leg attachment part of the prepreg for rod tube construction that is attached to the core metal, and the outer peripheries of these prepregs are bound with tape or heat-shrinkable tubes and heat-cured. Then, only one end portion of the built-up prepreg is ground until it reaches approximately the prepreg for forming the rod tube to form a thick portion and a male thread in the rod tube.
The fishing rod can be formed into a fishing rod in which the reel mounting leg can be directly attached to the surface of the rod tube without reducing the strength of the rod tube in the reel attachment part.

To efficiently manufacture a fishing rod having a male thread that is lightweight and has good operability.

Furthermore, in forming the male thread of the present invention, the built-up prepreg can be ground while rotating the core metal while it is still inserted into the core metal, so the grinding work is also smooth and simple. It has excellent features such as the male thread can be easily formed at any position on the fishing rod by arbitrarily selecting the position of polymerization and adhesion of the built-up prepreg at the same time as opening.
