Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a rotor which rotates around an axis by a winding driving force at a front position of a reel body, and a pair of arms which are opposed to the rotor with the axis interposed therebetween. Part is formed so as to project forward, and a thread guide part is formed on an arm cam supported at one front end of the pair of arm parts, and the thread guide part and the other arm part, or the front end of the other arm part. A spinning reel having a bail extending between a support arm supported by a shaft and a swingable arm cam so that the bail can be switched between a winding position and a releasing position. It is about the technology to take.

[0002]

2. Description of the Related Art In the spinning reel constructed as described above, there is a spinning reel constructed to balance the rotor as disclosed in Japanese Patent Laid-Open No. 5-38246. By setting the rocking axis of the arm cam with the inclined portion in the inclined posture, the weights of the yarn guide portion and the arm cam are offset by the supporting arms on the opposite sides to balance the weight, and the evenness of the rotor rotation It is configured to suppress the generation of force and enable smooth winding.

[0003]

DISCLOSURE OF THE INVENTION In this type of rotor,
Since the bale is placed at a position away from the rotor axis, it is also important to balance the weight of the bale in order to balance the rotation of the rotor.In the conventional example, the pair of arms are biased to the anti-bale side. The weight of the bail is offset by the weight of the arm portion by setting the position. However, since the weight of the bale acts on the front part of the rotor, the weight of the rear part of the rotor (the part on the reel body side) is biased to the anti-bale side if the entire arm part is deviated to the anti-bale side. However, there is room for improvement because it may cause the rotor to lose its balance subtly.

Further, in the conventional spinning reel, when the rotor is rotated in the winding direction, the bail in the releasing position is operated in the winding position by contact with the cam-shaped contact portion formed on the reel unit. There is also a mechanism in which a return mechanism for controlling the thread is built in the arm part on the thread guide part side (for example, in Japanese Utility Model Sho 62-805).
No. 70), a device provided with this type of return mechanism, and assuming that the entire arm portion is biased to the anti-veil side while maintaining the interval between the arm portions as described above, As a result of the rear end portion (the portion on the reel unit side) being separated from the rotor shaft center, the load at the time of rotating the handle in the winding direction to restore the bale to the winding posture increases, and Since it is necessary to separate the position of the contact portion formed on the main body from the axis of the rotor, it may be possible to increase the size of the reel main body.

It is an object of the present invention to reasonably construct a spinning reel that offsets the weight of the bale and improves the rotational balance of the rotor.

[0006]

The features of the present invention (Claim 1) are, as described at the beginning, a pair of arms which are opposed to each other with a shaft interposed therebetween with respect to a rotor provided at a front position of the reel unit. Part is formed so as to project forward, and a thread guide part is formed on an arm cam supported at one front end of the pair of arm parts, and the thread guide part and the other arm part, or the front end of the other arm part. In a spinning reel comprising a bail extending between a supporting arm supported by the arm and a swingable arm cam, the bail can be switched between a winding position and a releasing position and is orthogonal to the axis. In the directional view and in the directional view in which the pair of arm portions overlap, the widthwise central position of the rear end portion of the arm portion in the directional view is substantially aligned with the shaft core, and the thread guide portion is provided. Ah The pivot axis position of the cam, in a position facing each other across the axis and the bale winding posture, and, by setting the position spaced from the axis,
It is also used as a balance means for balancing the rotation of the rotor by the weight of the arm cam whose center of gravity is formed on the side opposite to the bale with respect to the axis, and its action and effect are as follows. .

[0007]

According to the above feature, since the position of the center of gravity of the arm cam is deviated to the anti-veil side, the weight of the bail can be offset by the weight of the arm cam.
The center in the width direction (width in the direction along the rotation direction of the rotor) of the rear ends of the pair of arm portions (portions on the reel body side) is
Since it is arranged at a position that overlaps with the shaft center when viewed in a direction orthogonal to the rotor shaft center, the weight distribution is biased at the rear end position of the rotor as compared with a case where this arm part is displaced. In addition, since the arm portion is formed at a symmetrical position with respect to the shaft center, the connecting portion between the rear end portion of the rotor and the arm portion when the rotor is rotated, as compared with the case where the arm portion is formed in an eccentric state. It is possible to maintain high strength without concentrating stress on.

That is, according to the present invention, since the arm cam portion is displaced to the side opposite to the bail side to constitute the balance means,
The imbalance caused by the weight of the bale can be eliminated without displacing the arm part as a whole, or without disposing a special balancer, or by simply using a relatively lightweight balancer. (The present invention does not hinder the combined use of a balancer.) Moreover, since the rear end of the arm does not deviate, the weight distribution of the rear end does not become uneven, and high strength is achieved without reinforcement. It will be released.

According to the second aspect of the present invention, since the bale has a substantially entire length on a plane, and the center of gravity of the bail exists on or is close to the plane, it is easy to stabilize the position of the center of gravity of the bale. Since the plane and the arm cam provided with the thread guide portion intersect or are arranged very close to each other, the arm cam is formed in a shape protruding forward as compared with a shape in which the middle portion of the bale protrudes forward. Without doing so, the weight of this arm cam (by the balancing means) can offset the total weight of the bale.

According to the third aspect of the present invention, since the center of gravity of each of the arm cam and the supporting arm is arranged at a position where they are opposed to each other with the shaft center sandwiched therebetween, the arm cam and the supporting arm are respectively provided with a balance as compared with the case where the weight of the arm cam is balanced. It is also possible to balance each other and even offset the weight of the bale with each weight.

According to the present invention, the weight of the bail can be offset by the weight portion formed on the arm cam.
It is possible to arrange the balancer at an appropriate position to achieve a highly accurate balance, as compared with the case where the weight of the entire arm cam is used to balance the rotor.

According to the fifth aspect, even if the rotor cannot be perfectly balanced by the arrangement of the arm cams, it is possible to achieve a highly accurate balance by properly disposing the balancer.

According to a sixth aspect of the present invention, the arm cam is provided in a deviated state to balance the rotor, and even if the arm mechanism is provided with a returning mechanism, the arm portion is deviated as compared with the case where the entire arm portion is deviated. Since the rear end position does not separate from the rotor axis, it is possible to suppress an increase in the force that acts on the handle from the return mechanism when the handle is operated, and the return mechanism operates without increasing the size of the reel unit. It becomes possible.

[0014]

Therefore, the spinning reel is rationally constructed in which the weight of the bail is offset to improve the rotational balance of the rotor and the fishing line can be smoothly wound.

Particularly, in the case where the bail is arranged on a plane, a good balance state can be obtained without the arm cam having a special shape (Claim 2). In the case where the arm cam and the supporting arm are provided, the arm cam and the supporting arm are provided. A good balance state can be obtained by the weight of each arm (claim 3), a highly accurate balance state can be obtained with the arm cam having a heavy weight portion (claim 4), and a balancer provided on the rotor Even if the arm cam and the bail cannot be brought into the balanced state, the balancer brings them into a good balanced state (Claim 5), and even if the return mechanism is constructed in the contact type,
The returning mechanism can be operated without making the returning operation heavy and without increasing the size of the reel unit (claim 6).
