JP 2009-273443 A (paragraph number [0017])

The fishing line guides are not always exposed to salt water or hot weather at fishing grounds, but receive the force from the fishing line through the guide ring and the weight of the fish caught by the weights and needles. It receives a bending moment and a torsional moment due to the load to be peeled from the body.
This moment is concentrated on the bent joint at the boundary between the leg and foot, and a large stress acts on the bent joint, causing cracks or breakage in that part, so that the fishing line guide It is necessary to replace this part, and it is considered to strengthen the part.
In addition, a load from the fishing line acts directly on the holding portion that holds the guide ring to generate a large stress, and there may be sufficient cracking or the like from the guide ring holding portion. Sufficient support capability is also required for the supporting legs.

  The object of the present invention is to cause cracks and breakage in the holding part, the leg part, and the bent connection part at the boundary part between the leg part and the foot part even when receiving the moment as described above. It is the point which provides the guide and fishing rod for difficult fishing lines.

In other words, by applying a reinforcing body made of fiber reinforced resin to at least a part including the holding part, the leg part, and the bent connection part, the cross-sectional modulus in those parts is increased and the mechanical strength is enhanced. Yes.
For example, as means for increasing the mechanical strength, it is conceivable to increase the thickness of those portions, or to change to a high-strength metal or the like, but if the thickness is increased, the weight increase is large, In addition, when changing to a metal having high strength, there is a drawback that the manufacturing cost is high.
On the other hand, in the present application, since the reinforcing body is formed by the fiber reinforced resin, the weight can be reduced as compared with the case where the plate thickness is increased, and compared with the case where the metal is changed to a high strength metal or the like. Thus, there is an advantage that the manufacturing cost can be easily maintained while maintaining the strength close to that of the metal.

〔effect〕
Therefore, by applying a reinforcing body made of fiber reinforced resin to at least a part including the holding portion, the leg portion, and the bent connection portion, without increasing the weight and suppressing an increase in manufacturing cost, compared to the conventional case.

[Action]
That is, by applying a reinforcing body made of fiber reinforced resin to the bending connection portion, the section modulus at the bending connection portion is increased, and the mechanical strength at the bending connection portion is enhanced.
For example, as a means for increasing the mechanical strength of the bent connection portion, increasing the thickness of the metal bent connection portion may be changed to a metal having high strength, but the thickness of the bent connection portion may be increased. For example, when the weight is increased and the metal is changed to a metal having high strength, there is a disadvantage that the manufacturing cost is high.
On the other hand, in the present application, since the reinforcing body is formed by the fiber reinforced resin, the weight can be reduced as compared with the case where the plate thickness is increased, and compared with the case where the metal is changed to a high strength metal or the like. Thus, there is an advantage that the manufacturing cost can be easily maintained while maintaining the strength close to that of the metal.

〔effect〕
Therefore, by applying a reinforcing body made of fiber reinforced resin to the bent connection portion, the bending connection portion is strengthened compared to the conventional one without increasing the weight and suppressing the increase in manufacturing cost.

However, when the whole holding part or the whole holding part and the leg part is made of the fiber reinforced resin alone, the rigidity becomes too high and the surface lacks toughness.
Therefore, a guide body is configured by combining a fiber-reinforced resin exterior portion and a metal holding portion.
And since the reinforcement body made from fiber reinforced resin is given to the bending connection part, the reinforcement | strengthening in a bending part is also made sufficiently.
With such a configuration, the mechanical strength can be sufficiently secured as compared with the case where the metal fishing line guide is simply thinned to reduce the weight.

Moreover, since the foot portion attached and fixed to the frame is made of metal, the toughness can be strengthened compared to the case where the foot portion is composed of a single exterior portion made of fiber reinforced resin, and for fishing lines. The guide can be mounted and fixed stably.
On the other hand, the metal part is exposed from the exterior part made of fiber reinforced resin to form the foot part, so that it is possible to impress the angler with the same mounting and fixing state as the conventional metal fishing line guide. , Can create a sense of stability.
