[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention prevents rotation of a rotor in a fishing line payout direction by engaging a tooth formed on a rotor or a member which rotates in connection with the rotor. A reverse rotation preventing mechanism having a stopper and a switching member for switching the stopper to one of a posture capable of engaging with the tooth portion or a non-engageable posture is provided, and the rotor or the rotor is linked to the rotor. The present invention relates to a spinning reel in which a rotating member is provided with a rolling-type one-way clutch mechanism that allows the rotor to rotate in a fishing line winding direction.

[0002]

2. Description of the Related Art Conventionally, as the above-mentioned reverse rotation preventing mechanism,
A ratchet wheel type in which a stopper is engaged with a tooth portion of a wheel is often used, and a ball or a roller provided with a roller for the purpose of eliminating asobi in a rotating direction when the reverse rotation preventing mechanism is used. Type one-way clutch mechanism (for example, Japanese Utility Model Laid-Open No. 64-389).
No. 63).

[0003]

[Problems to be Solved by the Invention] Here, considering the handling of spinning reels during actual fishing, depending on the type of target fish, the angler does not apply tension to the fishing line until the angler feels the hit, and feels the hit. Also, fishing in a form in which the fishing rod is tilted by a rod tilting operation is often performed. In this type of fishing, the fishing line is prevented from being fed out by the above-described reverse rotation prevention mechanism or the one-way clutch mechanism when the rod is tilted, and the fishing line is Tension acts on As described above, the reverse rotation prevention mechanism or the one-way clutch mechanism also has a function of preventing the fishing line from being fed out. When the drag mechanism is slid and exchanged with a large fish, the reverse rotation prevention mechanism or the one-way clutch mechanism is used. A relatively large load acts on the mechanism.

When the ratchet wheel type is used for the reverse rotation preventing mechanism, not only the timing of the awase is delayed due to asobi in the rotating direction, but also the shock at the time of the awase is large, so that the above-mentioned rolling type is used. It is also desired to provide a one-way clutch mechanism. However, the rolling-type one-way clutch mechanism has a favorable surface in which asobi is hardly generated, but has a contact area between the roller and the shaft body or between the roller and the outer race as in the above-described conventional structure. When interacting with large fish, where high strength cannot be obtained due to small size,
There is room for improvement, as strong awase operations can damage the device. By the way, if a one-way clutch mechanism that withstands such a relatively large load is selected from commercially available ones, the one-way clutch mechanism becomes large in the radial direction, and becomes impractical in terms of weight and size of the reel. . An object of the first invention is to prevent the fishing line from being pulled out strongly without damaging the good surface of using a rolling type one-way clutch mechanism, and without increasing the size of the reel. An object of the present invention is to provide a mechanism that can perform an operation on a mechanism in a satisfactory manner.

[0005]

According to a first aspect of the present invention, when a rotational force is applied to the rotor in a fishing line payout direction, the rotation of the rotor until the tooth portion and the stopper reach an engaged state. A brake mechanism for applying a braking force to the rotation via the one-way clutch mechanism while allowing the rotation to prevent the stopper and the tooth portion from engaging with each other by the switching member. A release mechanism for releasing the action of the braking force from the braking mechanism in conjunction with the setting operation of the mechanism is provided, and the action and effect are as follows.

[0006]

When a rotational force is applied to the rotor and the rotating system to the rotor in the fishing line payout direction by the tension from the fishing line, the braking force of the braking mechanism acts on the one-way clutch mechanism to rotate the one-way clutch mechanism. And the one-way clutch mechanism restricts the rotation of the rotor to prevent the fishing line from being fed out. When the tension of the fishing line is large, such as when a large fish is hooked, a braking force is exerted on the one-way clutch mechanism even if there is an interval until the stopper and the teeth engage. Since the slip occurs in the braking mechanism, the one-way clutch mechanism and the rotor restrained by the one-way clutch mechanism allow the rotor to rotate in the fishing line payout direction. The engagement of the stopper with the tooth portion prevents the rotation of the rotor from being stopped and simultaneously prevents the fishing line from being fed out. In other words, in this invention, as a mechanism for preventing the rotation of the rotor in the fishing line payout direction, a reverse rotation preventing mechanism and a rolling type one-way clutch mechanism are used, and two types of mechanisms having different properties are used, so that no asobi occurs. Thus, the rotation can be prevented, and the breakage can be suppressed even if the one-way clutch mechanism has a relatively small capacity as in the conventional case. When the reverse rotation prevention mechanism is switched by the switching member so that the stopper and the tooth portion can be engaged with each other, the braking mechanism is activated, and when the rotor attempts to reversely rotate, the braking mechanism is switched to the one-way clutch mechanism. To apply a braking force to the rotor. When the reverse rotation preventing mechanism is switched by the switching member such that the stopper and the tooth portion cannot be engaged with each other, the braking mechanism is deactivated by the release mechanism, and the braking force against the forward / reverse rotation operation of the rotor is not applied. .

[0007]

Therefore, a spinning reel that strongly prevents the fishing line from being fed out without impairing the good surface of using the rolling type one-way clutch mechanism and without increasing the size of the reel is reasonable. It was able to be configured. Further, the switching of the operation and non-operation of the braking mechanism can be performed by operating the switching member, and there is no need to provide a dedicated operating tool for the switching of the operation and non-operation of the braking mechanism, and it is not necessary to perform the operation only for the braking mechanism. Absent. In addition, by providing a release mechanism for the braking mechanism, one that does not have such a release mechanism (for example, Japanese Utility Model Publication No. 55-38)
380 publication also has the following effects. That is, since the braking force can be automatically released, the rotor is easily rotated in reverse. Then, since the rotor rotates without resistance even if the fish pulls the food in addition to it, the thread is smoothly fed out, and the fish swallows the food without doubt. By paying attention to the payout of the line at the time of the reverse rotation of the rotor, the result of the fishing can be improved, and there is also an effect that the line is hardly twisted. An object of the second invention is to provide a braking mechanism capable of exhibiting a good braking force in addition to the object of the first invention.

[0008]

According to a second feature of the present invention, a transmission shaft for transmitting a driving force from a handle to the rotor is set as a member rotating in cooperation with the rotor,
The reverse rotation preventing mechanism is constituted by a gear-like tooth formed at an inner position of the reel body of the transmission shaft, and a stopper that can be freely disengaged from the tooth.
The effects are as follows.

[0009]

Since the reverse rotation preventing mechanism is constituted by the gear teeth and the stopper, a strong braking force can be exerted by the engagement between the gear teeth and the stopper.

[0010]

[Effects of the Invention] Accordingly, the braking force can be strongly exerted even against a large force that cannot be overcome by the one-way clutch mechanism alone, and the size of the reel can be greatly reduced by avoiding an increase in the size of the one-way clutch mechanism. I can contribute. Book 3
The purpose of the invention is to provide, in addition to the object of the first invention, a braking mechanism which can exhibit good braking force and which is excellent in strength.

[0011]

According to a third aspect of the present invention, the reverse rotation preventing mechanism comprises a tooth formed on the inner surface of the rotor and a stopper which is detachable from the tooth. The operation and effect are as follows.

[0012]

By forming the teeth on the inner surface of the rotor,
A large number of teeth can be provided at the same interval as when the gear is mounted on the transmission shaft.

[0013]

Accordingly, even if the reverse rotation preventing mechanism is a ratchet type, the rotor can be stopped with a finer rotation phase.

The object of the fourth invention is to provide, in addition to the object of the first invention, a one-way clutch mechanism which can exert a good braking force and is excellent in strength.

[0015]

According to a fourth aspect of the present invention, the one-way clutch mechanism comprises a roller or a ball interposed between an inner race and an outer race, and the one-way clutch mechanism includes a one-way clutch mechanism. The inner race of the one-way clutch mechanism is externally fitted and fixed to the transmission shaft that drives the rotor, and an actuated part is formed on which the braking force from the braking mechanism acts on the outer race of the one-way clutch mechanism. The operation and effect are as follows.

[0016]

When the rotor is to rotate in the reverse direction, the movement of the outer race is restricted by the braking force of the braking mechanism, and the rotation of the inner race and the transmission shaft is stopped by the outer race. To block.

[0017]

[Effect of the Invention] Therefore, as a one-way clutch mechanism,
Compared to a case where the rotor is mounted on the inner peripheral surface of the rotor or the like, the rotor can be made compact while maintaining the required strength configuration.

Further, the spring 23 exerts an urging force so as to cause the friction holding portion 20 to slip at a lower value than when the force from the cylinder shaft 9 reaches a limit at which the rolling type one-way clutch mechanism B is broken. You have set.

When a rotational force is applied to the cylinder shaft 9 in the fishing-line feeding direction by the tension from the fishing line, the rolling-type one-way clutch mechanism B immediately restrains the cylinder shaft 9 to feed the fishing line. For example, even when a large fish is caught, after the rolling out of the fishing line is prevented by the rolling type one-way clutch mechanism B, the frictional holding portion 20 causes a slip and the fishing line drawing out direction of the cylinder shaft 9. The rotation of the cylinder shaft 9 is stopped simultaneously with the stop of the rotation of the cylinder shaft 9 by the engagement of the stopper 15 with the wheel 14 of the ratchet wheel type reverse rotation prevention mechanism A while allowing the rotation of the cylinder type 9 to avoid the damage of the rolling type one-way clutch mechanism B.

The position is different. That is, the swing angle of the swing arm 30 is made larger than the swing angle of the arm cam 29. As shown in FIG. 10, a contact portion 30A is formed on the swing arm 30, and the arm 4D of the rotor 4 is formed.
