Description

[Detailed Description of the Invention] Purpose of the Invention The present invention relates to a main rod of a secondary fishing rod that allows easy attachment of a reel.

Prior Art To attach a reel to a fishing rod, a reel seat is fixed to the fishing rod and the reel is attached to the reel seat. However, when fixing a plate-shaped reel seat to the fishing rod, it is necessary to attach the reel to the fishing rod along the circumferential surface of the fishing rod. There is a defect in that if it is not installed firmly, it will easily move in the circumferential direction and become unstable.

In order to improve this problem, it was discovered in 1983 that the cross section of the fishing rod reel seat attachment part was formed into a polygon.
This is known from Publication No. 92664, but since the fingers of the hand that grips the reel attachment part come into contact with the polygonal cross-sectional part, it is difficult to grip it, and if you hold it for a long time, your fingers will get sore, and the strength of the fishing rod will be reduced. In addition, the strength reduction due to the step at the front of the reel seat fixing part, which is the part where the load is concentrated especially during fishing operations, combined with the strength reduction due to the polygonal cross section, further weakens the strength of the fishing rod. In addition to this, it is also impossible to remove the core metal when the fishing rod is integrally molded, making it extremely difficult to manufacture and mass-producing the fishing rod.

Structure of the invention The present invention is an improvement on such defects, and is made by impregnating reinforcing fibers with a thermosetting synthetic resin and integrally molding the main rod, which has a circular cross section. One side of the main rod has a thickness that is approximately the same as the circular cross section in the axial direction. A flat surface for placing a reel sheet is formed which is thick and has a planar outer circumferential surface and an inner circumferential surface, and the front end of the flat surface for placing the reel sheet is made smooth without creating a step in the circular cross-sectional part of the main rod. The gist is that it is continuous.

An embodiment of the present invention will be explained with reference to the drawings. The main rod 1 of the vertical fishing rod is formed into a hollow shape with a circular cross section by impregnating reinforcing fibers such as glass fiber, carbon fiber, and aromatic polyamide fiber with a thermosetting synthetic resin. At the same time, in the axial direction of one side thereof, a flat surface 3 for placing a reel sheet is formed, the outer peripheral surface and the inner peripheral surface of which are planar and having approximately the same thickness as the circular cross section. The front end of the rod smoothly continues with the circular section of the tip of the main rod without any steps.

Therefore, it is preferable that the main rod 1 is formed by using reinforcing fibers made of braided tubes that intersect in a twill pattern, and impregnating the reinforcing fibers with a thermosetting synthetic resin liquid. It may also be formed by winding and molding a prepreg impregnated with a thermosetting synthetic resin.

Furthermore, a reinforcing layer 1' may be provided on the inner surface of the grip portion at the base of the main rod 1 and the inner surface of the joint portion of the tip.

Since the embodiment of the present invention is constructed as described above, a plate-shaped reel sheet is wound around the flat surface 3 for placing the reel sheet of the base rod 1 with a mounting thread and further fixed with a synthetic resin, and the reel is attached to this. Fishing operations are performed while wearing the reel and grasping the reel attachment part.

Effects of the invention In this invention, a flat surface for placing the reel seat is formed in the axial direction on one side of the base rod, which is made by impregnating reinforcing fibers with a thermosetting synthetic resin and integrally molded. The reel seat can be stably fixed on a flat surface for mounting the reel seat, and the reel seat can be securely mounted by preventing the reel seat from moving in the circumferential direction due to the conventional fishing line winding action. Even if you hold the attachment part for a long time, the fingers of the hand you are gripping will comfortably touch the circumferential surface on the lower side of the flat surface for placing the reel seat, and you will not feel any pain, and you can grip it firmly. You can carry out fishing operations smoothly and easily by holding the handle.

In addition, the present invention prevents only the flat surface for placing the reel sheet from becoming locally thin, and forms it to approximately the same thickness as the circular cross-sectional part, thereby preventing a decrease in strength due to the formation of the flat surface for placing the reel sheet. The weight of the main rod can be reduced.

Furthermore, in the present invention, the front end of the flat surface for placing the reel seat is formed so as to be smoothly continuous with the circular cross-sectional part of the main rod without any step, so that the reel can be easily moved by the load concentrated on the front part of the reel seat during fishing operations. The flat surface for placing the sheet reliably prevents a decrease in strength due to damage to the front end, and the fact that the flat surface for placing the reel sheet is continuous with the circular section allows the core to be pulled out when the main rod is integrally molded. Therefore, the main rod is easy to manufacture and can be mass-produced, and therefore has excellent features and practicality in that it can provide an easy-to-operate, lightweight and strong main rod at a low cost.
