Description

The present invention relates to a rotor, and more particularly to a spinning reel rotor rotatably mounted on a reel body for guiding fishing line to a spool.

Generally, a spinning reel includes a reel body having a handle, a spool mounted on the reel body movably back and forth, around which a fishing line is wound, and a rotor rotatably supported by the reel body to wind the fishing line around the spool. (For example, see Patent Document 1). The rotation of the handle is normally transmitted to the rotor via a face gear and a pinion gear meshing with the face gear.

The rotor includes a cylindrical portion non-rotatably mounted on a pinion gear rotatably supported on a reel body, first and second rotor arms disposed opposite each other on a rear outer peripheral surface of the cylindrical portion, and both rotor arms. And a bail arm that is swingably mounted on the tip of the bail arm. Both rotor arms are integrally formed with the cylindrical portion, and extend from the cylindrical portion radially outward in a trapezoidal shape while smoothly reducing the width, and then bend substantially 90 degrees and extend forward.
JP-A-7-246045

で は In the conventional rotor, both of the two rotor arms are bent from the cylindrical portion and extend forward. Therefore, when a load from the fishing line acts on the rotor arm, stress concentration tends to occur at the bent portion. In order to maintain high strength so that the rotor arm is not damaged even if stress concentration occurs at the bent portion, it is necessary to increase the thickness of the portion. As a result, the mass of the rotor increases, making it difficult to reduce the weight of the rotor.

The object of the present invention is to make it possible to maintain high strength while reducing the weight of the rotor.

A rotor of a spinning reel according to a first aspect of the present invention is a rotor rotatably mounted on a reel body and guiding a fishing line to a spool, and includes a cylindrical portion, first and second rotor arms, and a bail arm. I have. The cylindrical portion is rotatably mounted on the reel body. The first and second rotor arms are provided with the first and second connecting portions opposed to each other on the rear outer peripheral surface of the cylindrical portion, and forwardly curved outwardly from the first and second connecting portions, respectively. The first and second arm portions each have a tapered shape in which the width in the rotation direction becomes narrower as it extends. The bail arms are swingably attached to the tips of both rotor arms.

ロ ー タ The rotor of this spinning reel is formed by extending and extending two rotor arms forward while bending outward from the cylindrical portion. For this reason, there is no bent portion, and stress concentration does not occur in that portion, so that the stress is averaged and the strength can be maintained high without increasing the thickness of the rotor arm. Therefore, high strength can be maintained while reducing the weight of the rotor.

A rotor for a spinning reel according to a second aspect of the present invention is the rotor according to the first aspect, wherein the first and second connection portions are formed smoothly and continuously in a circumferential direction with the cylindrical portion, and the first and second arm portions are provided. Are formed smoothly and continuously with the first and second connection portions, and extend forward with an interval from the cylindrical portion. In this case, since the cylindrical portion and the connecting portion, and the connecting portion and both the arm portions are formed smoothly and continuously, respectively, stress is less likely to be concentrated even at those continuous portions, and the strength can be maintained higher.

A spinning reel rotor according to a third aspect of the present invention is a rotor that is rotatably mounted on a reel body and guides fishing line to a spool, and includes a cylindrical portion, first and second rotor arms, and a bail arm. I have. The cylindrical portion is rotatably mounted on the reel body. The first and second rotor arms are opposed to each other on the rear outer peripheral surface of the cylindrical portion, and are formed smoothly and continuously in the circumferential direction with the cylindrical portion. The first and second arm portions each have a tapered shape that is formed smoothly and continuously with the portion and that extends forward and is spaced apart from the cylindrical portion, and that has a reduced width in the rotational direction as it extends. The bail arms are swingably attached to the tips of both rotor arms.

In the rotor of this spinning reel, the cylindrical portion and the two connecting portions of the first and second rotor arms are smoothly and continuously formed in the circumferential direction, and the two connecting portions and the two arm portions are separately smooth. Since they are formed continuously, the concentration of stress between them is reduced, the stress is averaged, and the strength can be maintained high without increasing the thickness of the rotor arm. Therefore, high strength can be maintained while reducing the weight of the rotor.

A rotor for a spinning reel according to a fourth aspect of the present invention is the rotor according to any one of the first to third aspects, wherein at least one of the first and second connection portions is disposed on the rear outer peripheral surface of the cylindrical portion at an interval in the circumferential direction. And two of the first arm and the second arm, which are continuous with the two legs, are gathered together at the tip to support the bail arm in a swingable manner. In this case, at least one of the two rotor arms has a structure in which the distal end portions are gathered and the proximal end portion is separated in the circumferential direction and is divided into two forks, so that the weight can be further reduced. In addition, since the base end portion expands in the circumferential direction, the rigidity of the rotor arm in the circumferential direction is increased, and the strength can be maintained higher.

A rotor for a spinning reel according to a fifth aspect of the present invention is the rotor according to any one of the first to fourth aspects, wherein the bail arm is mounted on the first and second rotor arms so as to swing freely, respectively. A member, a line roller rotatably mounted on the tip of the first bail support member, a fixed shaft cover fixed to the first bale support member across the line roller, a second bail support member and a fixed shaft cover. And a veil connecting the two.

The spinning reel rotor according to a sixth aspect of the present invention is the rotor according to the fifth aspect, wherein the first bail support member is swingably mounted on the outside of the first rotor arm by a hexagon socket head cap screw. In this case, since the first bail support member is attached to the first rotor arm by the hexagonal bolts having less outer surface catching, even if the fishing line comes into contact with the outer surface of the first bale support member, it is less likely to be caught. Become.

According to the present invention, the two rotor arms are formed to have a tapered shape in which the width in the rotation direction becomes narrower as the two rotor arms extend forward and extend outwardly while bending outward from the cylindrical portion. For this reason, there is no bent portion, and stress concentration does not occur in that portion, so that the stress is averaged and the strength can be maintained high without increasing the thickness of the rotor arm. Therefore, high strength can be maintained while reducing the weight of the rotor.

The rear end of the spool shaft 15 is fixed to the slider 22 so as not to rotate. The intermediate gear 23 meshes with the pinion gear 12.

As shown in FIG. 3, the rotor 3 has a cylindrical portion 30 and first and second rotor arms 31 and 32 provided on the sides of the cylindrical portion 30 so as to face each other. The cylindrical portion 30 and the rotor arms 31, 32 are made of, for example, an aluminum alloy and are integrally formed. A front wall 33 is formed at the front of the cylindrical portion 30, and a boss 33a is formed at the center of the front wall 33. A through hole is formed in the center of the boss 33a, and the front portion 12a of the pinion gear and the spool shaft 15 pass through the through hole. The nut 13 is disposed at a front portion of the front wall 33, and a bearing 35 that rotatably supports the spool shaft 15 is disposed inside the nut 13.

As shown in FIGS. 1 and 5, the first rotor arm 31 has a first connection portion 31 a disposed on the outer peripheral surface of the rear portion of the cylindrical portion 30, and a front portion that curves outward from the first connection portion 31 a while protruding outward.

I have. The line roller 41 is rotatably mounted on the tip of the first bail support member 40. The fixed shaft cover 47 has a deformed conical shape with a sharp tip.

The second rotor arm 32 has a second connecting portion 32a disposed on the outer peripheral surface of the rear portion of the cylindrical portion 30, and a second arm portion 32b extending forward from the second connecting portion 32a while curving outward. are doing. The second connection portion 32a is formed smoothly and continuously in the circumferential direction with the cylindrical portion 30, and has two legs 32c arranged at intervals in the circumferential direction of the cylindrical portion 30. The second arm portion 32b is formed smoothly and continuously with the second connection portion 32a, and extends forward with an interval from the cylindrical portion 30. The second arm portion 32b bifurcates from the distal end toward the connection portion with the cylindrical portion 30, and is connected to the cylindrical portion 30 by two legs 32c. Therefore, an opening 32d is formed inside. A second bail support member 42 is swingably mounted on the inner peripheral side of the distal end of the second rotor arm 32. The outer peripheral surface of the second arm portion 32b is also formed in an arc shape centering on the axis of the spool shaft 15.

ロ ー タ In the rotor 3 configured as described above, since the rotor arms 31 and 32 are formed to be curved convexly outward, there is no bent portion, and stress concentration does not occur at that portion. Therefore, the stress is averaged, and the strength can be maintained high without increasing the thickness of the rotor arm. Therefore, the strength can be maintained high while the weight of the rotor 3 is reduced. In addition, since the cylindrical portion 30 and the two connecting portions 31a, 32a and the two connecting portions 31a, 32a and the two arm portions 31b, 32b are respectively formed smoothly and continuously, stress is less likely to be concentrated even at those continuous portions. And the strength can be maintained higher. Further, since the distal end portions of the second rotor arms 32 are gathered and the proximal end portions are separated in the circumferential direction and divided into two forks, the weight can be further reduced. Further, since the base ends of both rotor arms 31 and 32 expand in the circumferential direction, the rigidity of the rotor arms in the circumferential direction is increased, and the strength can be maintained higher.

ベ ー A veil 43 having a shape obtained by bending a wire into a substantially U-shape is fixed between the distal end portion of the fixed shaft cover 47 and the second bail support member 42. The first and second bail support members 40 and 42, the line roller 41, the bail 43, and the fixed shaft cover 47 constitute a bail arm 44 for guiding the fishing line to the spool 4. The bail arm 44 is swingable between a yarn guiding posture shown in FIG. 3 and a yarn releasing posture reversed from the yarn guiding posture.

A cover 45 is mounted on the outer peripheral side of the first bail support member 40, and inside the cover 45, the bail arm 44 is returned from the line releasing position to the line guiding position in conjunction with the rotation of the rotor 3, and both ends are returned. A bail reversing mechanism 46 for maintaining the state in the posture is arranged. Inside the cylindrical portion 30 of the rotor 3, a reverse rotation preventing mechanism 50 for prohibiting and releasing the reverse rotation of the rotor 3 is arranged. The reverse rotation prevention mechanism 50 has a roller-type one-way clutch 51 in which the inner ring idles, and a switching mechanism 52 that switches the one-way clutch 51 between an operating state (reverse rotation prohibited state) and a non-operating state (reverse rotation permitted state). I have.

The spool 4 is disposed between the first rotor arm 31 and the second rotor arm 32 of the rotor 3, and is mounted on the tip of the spool shaft 15 via a drag mechanism 60. The spool 4 has a bobbin trunk 4a around which a fishing line is wound, a skirt 4b integrally formed at the rear of the bobbin trunk 4a, and a flange plate 4c fixed to the front end of the bobbin trunk 4a. ing. The bobbin trunk 4a is a straight cylindrical member, and the outer peripheral surface is formed by a peripheral surface parallel to the spool shaft 15. The bobbin trunk 4a is rotatably mounted on the spool shaft 15 by two bearings 56 and 57. The flange plate 4c is fixed to the bobbin trunk 4a by a spool ring collar 55 screwed to the inner peripheral surface of the bobbin trunk 4a.

[Reel operation and operation]
At the time of casting, the bail arm 44 is turned over to the line releasing position with the handle 1 attached to the left position shown in FIG. Thereby, the first bail support member 40 and the second bale support member 42 swing. In this state, the fishing rod is cast while catching the fishing line with the index finger of the hand holding the fishing rod. Then, the fishing line is released vigorously by the weight of the device. In this state, when the handle 1 is rotated in the line winding direction by, for example, the left hand, the rotor 3 is rotated in the line winding direction by the rotor driving mechanism 5, the bail arm 44 is returned to the line guiding posture by the bail reversing mechanism 46, and the fishing line is spooled. 4 wrapped around.

When the handle 1 is rotated in the line winding direction, the rotor 3 rotates in the line winding direction via the face gear 11 and the pinion gear 12, and the fishing line guided by the bail arm 44 is wound around the outer periphery of the spool 4. In such a case, the rigidity of the rotor arms 31, 32 is maintained even if the fishing line is loosened and entangled with one of the bail support members 40, 42, so that the rotor arms 31, 32 are not easily damaged. In addition, since both rotor arms 31 and 32 are reduced in weight, the handle 1 can be rotated with a small force when the handle 1 is rotated.

[Other embodiments]
In the above-described embodiment, the second rotor arm 32 is configured by a forked arm portion, but the first rotor arm 31 may be configured by a forked arm portion similarly to the second rotor arm 32. In this case, the bail reversing mechanism 46 may be provided separately without being provided inside the first rotor arm 31. This improves the rotational balance of the rotor.
