Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a bail arm of a spinning reel for fishing.

[Conventional technology]

In the spinning reel, as shown in FIGS. 3 and 4, a rotor b is rotatably supported at a fixed position on a reel body c with respect to a spool a that reciprocates in the front-rear direction. The bail arm e is attached to the arm portions d and d ′ provided symmetrically on the outer peripheral portion of the vehicle so that it can be raised and lowered via a bail arm cam and a bail arm lever (not shown). The fishing line (not shown) wound around the spool a is drawn out in a state of being tilted to the position shown by the two-dotted line in FIG. Is configured to be wound on a spool.

That is, when winding the fishing line, when the rotor b is rotated, the bail arm e is configured to rotate together with the rotor b in a state of projecting outward from one side of the rotation center.

However, the conventional bail arm is made of a solid wire material such as stainless steel, duralumin, and titanium, and is heavy in weight.Therefore, there is a problem in reducing the weight of the spinning reel. Since it is offset in terms of weight,
There is a problem that it is very difficult to balance the rotation of the rotor assembly. Therefore, conventionally, as a reel made for the purpose of reducing the weight of the spinning reel and facilitating the rotational balance of the rotor assembly, that disclosed in Japanese Utility Model Laid-Open No. 187268/1983 is known. The structure is such that the bail arm is made of a synthetic resin material having elasticity to reduce the weight and facilitate rotation balance.

However, in the case of the conventional structure, since the bail arm is made of a synthetic resin having elasticity, it is weak in strength and easily deformed or damaged during transportation or during use. Therefore, there is a problem that a scratch is likely to be formed due to friction with the fishing line, and the fishing line is caught by the scratch and is not guided to a fishing line guide roller (not shown).

[Problems to be solved by the invention]

The present invention is intended to solve the above-mentioned problems. By forming the arm main body with a metal pipe to reduce the weight, it is possible to easily balance the rotation of the rotor assembly, and it is strong enough for transportation and use. In addition to providing a bail arm that is unlikely to be deformed or damaged at any time and is not easily scratched, when the bail arm body is formed, the hollow portion of a bent or curved portion is crushed and the cross-sectional shape becomes irregular and the crushing is prevented. The purpose is to solve the problem that the fishing line is caught in the generated place.

[Means for solving problems]

That is, the present invention solves the above-mentioned problems by filling a hollow portion of a metal pipe at least where it is bent or curved with a synthetic resin and bending or bending the portion filled with the synthetic resin. is there.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to the drawings. As shown in FIGS. 1 and 2, the arm main body 1 is formed of at least a metal pipe 1a made of aluminum, duralumin, stainless steel or the like. The hollow portion 2 at a curved or curved portion is partially or entirely filled with the synthetic resin 3, and the portion filled with the synthetic resin 3 is bent or curved.

As a part of the hollow part 2 where the synthetic resin 3 is partially filled, the bent parts 4 at both ends of the arm body 1 are bent so that they can be attached to a bail arm cam and a bail arm lever (not shown). 5 and the curved portion 6 of the arm body 1, and other parts that require strength as a bail arm. By thus filling the hollow portion 2 with the synthetic resin 3, it is possible to prevent the bent portions 4, 5 and the curved portion 6 from being crushed at the time of molding, and at the same time, to reinforce them.

Further, the synthetic resin 3 is filled with molten resin, for example, by an injection molding machine or the like in the entire hollow portion 2 or in the bent and curved portions before bending the arm body 1 so that the molten resin is completely filled. Before it is solidified, it is bent, curved and bent into a predetermined shape, or a wire made of thermoplastic resin is inserted into a desired portion of the hollow portion 2 of the metal pipe 1a in advance and then folded into a predetermined shape. The arm body 1 may be formed by bending or bending.

[Effect of device]

Since the bail arm of the spinning reel according to the present invention is constructed as described above, since the arm body 1 is lightly molded by the metal pipe 1a, the weight deviation is extremely small, and therefore the rotor is made smaller. It becomes easier to balance the rotation of the sub-assembly, and when compared to a synthetic resin bail arm, it will not be scratched due to friction with the fishing line, and at least the hollow part 2 where it is bent or curved is reinforced, Since the synthetic resin 3 is filled to prevent crushing when bending or bending, crushing does not occur at the bending or bending portion during molding, and the arm body 1 is formed into a predetermined cross-sectional shape and a desired shape. It has advantages that it can be molded well, fishing line is not caught, sufficient strength is obtained, and it is effective in reducing the weight of the reel.
