[Detailed description of the device]

[0001]

[Industrial applications]

 According to the present invention, a male screw portion is provided at one end of the reel seat portion in the axial direction to allow the movable hood to move in a threaded manner, and a female screw portion that is screwed to the male screw portion is attached to the movable hood. And a reel leg receiving portion for inserting and fixing the reel leg portion.

[0002]

[Prior art]

 In the fishing rod with the above configuration, the screw diameter of the male screw portion is set so that the movable hood and the outer diameter of the reel mounting portion are substantially continuous with each other while the reel is fixed to the reel mounting portion of the reel seat portion. It is formed to be smaller than the outer diameter of the reel mounting portion. In the conventional configuration having such a configuration, the male screw portion is continuously provided to one end of the reel mounting portion in a state in which the axis is aligned.

[0003]

[Problems to be solved by the device]

 Therefore, a step due to the difference in outer diameter between the male screw part and the reel mounting part is formed at the connection part, and when the reel is fixed by the movable hood, the tensile stress applied to the male screw part and The stress resulting from bending stress concentrates on the step portion, and excessive stress acts on the step portion. Also, when the movable hood is screwed to fix the reel leg, the reel leg has a tapered surface, so tightening with the movable hood will prevent the leg from reacting to the tapered surface. Since the force is only applied to a part of the taper surface in the circumferential direction, there is a problem in strength such as cracking at the open end of the taper surface.A metal frame is fitted over this open end. I was trying to improve the strength. However, with this, the weight of the metal frame increases, which makes it difficult to operate the rod, and there is still room for improvement. An object of the present invention is to provide a fishing rod that suppresses the application of excessive stress to the male screw portion and that can prevent damage at the tip opening while achieving the weight reduction of the movable hood. .

[0004]

[Means for Solving the Problems]

 According to a characteristic configuration of the present invention, a taper joint shaft portion having a larger diameter on the reel mounting portion side is disposed between one end of the reel mounting portion formed on the reel seat portion and the male screw portion. In addition to connecting the two, the outer diameter of the connecting end of the taper joint for the reel mounting portion is larger than the tip opening diameter of the movable hood. On the street.

[0005]

[Action]

 (A) By connecting the reel mounting part and the male screw part with the taper joint shaft part, the reel mounting part and the male screw part can be connected without a step, and stress concentration at the connecting part can be relaxed. . (B) Moreover, when the movable hood is screwed to fix the reel leg portion on the reel fixing surface, the reel leg receiving portion of the movable hood abuts the reel leg portion and, at the same time, the reel leg of the movable hood. The reel leg is completely fixed at the position where the part located on the opposite side of the receiving part 180 ° comes into contact with the taper joint shaft part (this can be fixed to the movable hood itself, whether it is made of metal or plastic). Since some elasticity is recognized and there is rattling, it is difficult to judge at which point it is completely tightened due to its elasticity, but the reel leg receiving part and this reel It can be better sensed that the tightening is completed by simultaneously contacting the reel leg and the taper joint shaft with the part located on the opposite side of the leg receiving part by 180 °). Therefore, the force applied to the tip open end of the movable hood when fixing the leg part of the reel is distributed to the two parts from the reel leg part and the taper joint shaft part, and the tip open end of the movable hood is distributed. The stress applied to each surface of, especially the surface pressure, will be reduced by half.

[0006]

[Effect of device]

 From the effect (a), stress concentration can be relieved at the taper joint shaft part while maintaining the different diameters of the male screw part and the reel mounting part. Therefore, the outer diameter of the male screw part can be reduced accordingly. There is no need to increase the diameter or improve the material to match the outer diameter. Due to the action (b), stress is evenly applied to the reel leg receiving portion and the portion located on the opposite side of the reel leg receiving portion, so that a metal reinforcing frame or the like is attached to the tip opening of the movable hood. There is no need, and the weight can be contributed to that much, and the rod can be operated easily.

【Example】

 As shown in FIG. 4, the reel seat portion 2 is arranged on the tip side of the grip 1 made of cork, and the fixed hood 3 is integrally formed at the end of the reel seat portion 2 on the rod end side, and the main rod 4 Then, the movable hood 5 is arranged on the rod tip side of the reel seat portion 2 to form a fishing rod for a lure to which the spinning reel 6 is attached. As shown in FIG. 1 to FIG. 4, the reel mounting portion 11 of the reel seat portion 2 finishes both side surfaces in a substantially circular cross section into curved surfaces 11A in a state of being substantially vertical and forms a leg portion 6A of the reel 6. When gripping the reel mounting portion 11 with the reel mounting portion 11, the grip portion is thinned to facilitate gripping. The structure for the movable hood 5 will be described. A small-diameter shaft portion is integrally extended from the reel mounting portion 11 of the reel seat portion 2, and a male screw is formed on the small-diameter shaft portion to form a male screw portion 7. From the male screw portion 7, the reel mounting portion 2 is formed. A taper joint portion 8 is formed on the side, and the male screw portion 7 and the reel mounting portion 11 are integrated to form a reel seat portion 2. A flat reel mounting surface a on which the leg portion 6A of the reel 6 is mounted is formed from the movable hood 5 to the reel mounting portion 11, the taper joint shaft portion 8, and the downward surface of the male screw portion 7. The external thread of the threaded portion 7 and the tapered surface of the tapered joint shaft portion 8 are not formed. The relationship between the outer diameters of the male screw portion 7, the taper joint shaft portion 8 and the reel mounting portion 11 is as follows. That is, the screw diameter of the male screw portion 7 is smaller than the outer diameter of the reel mounting portion 11, and the taper joint shaft portion 8 has the same diameter as the screw bottom diameter of the male screw portion 7 as the minimum diameter. The diameter increases toward the side of the portion 11. The diameter of the connecting portion of the tapered joint shaft portion 8 to the reel mounting portion 11 is set to be larger than the diameter of the tip opening of the movable hood 5. In contrast to this structure, the movable hood 5 is integrally fitted and fixed to the nut member 9 and the nut member 9 in which the female screw portion 9A screwed into the screw of the male screw portion 7 is formed. The outer layer member 10 is formed, and a reel receiving portion 9B for fixing the leg portion 6A of the reel 6 is formed at the opening end portion of the nut member 9 on the tip side of the female screw portion 9A. The reel receiving portion 9B has a tapered surface whose diameter increases toward the tip opening side in correspondence with the taper of the leg portion 6A of the reel 6.

With the above-described structure, when the movable hood 5 is screwed with the leg 6A of the reel 6 placed on the reel placing surface a, the opening of the nut member 9 tapers the reel leg 6A. The reel leg portion 6A is fixed by coming into contact with the tapered surface of the shaft portion 8. In this way, the movable hood 5 contacts the leg portion 6A of the reel 6 and the taper joint shaft portion 8 positioned 180 ° opposite to the leg portion 6A, so that the fixed posture is stable without rattling. To do.
