DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing spinning reel having a reduced rotating frame.

[0002]

2. Description of the Related Art JP-A-9-168353, JP-B-57-8693, JP-A-8-9843, JP-B-4-23410, and JP-A-50-137292.
The publication discloses a spinning reel for fishing.

[0003] These spinning reels for fishing have a rotating frame supported by a reel body that rotates in conjunction with operation of a handle. A pair of arms are attached to the rotating frame, and a bail arm is reversibly connected to the pair of arms at a fishing line discharge position and a fishing line winding position. In addition, a spool that reciprocates back and forth on the center of rotation of the rotating frame in conjunction with operation of the handle is supported at the front of the reel body via a spool shaft. When the handle is turned while the bail arm lever is at the fishing line winding position, the bail arm rotates around the spool together with the rotating frame, and at the same time, the spool reciprocates back and forth. As a result, the fishing line pulled by the bail arm is wound around the spool. Also,
When the bail arm lever is in the line release position, the line is released from the bail arm lever and can be released from the spool.

[0004]

However, the skirt portion of each spool has a cylindrical shape, and in order to prevent the fishing line from being caught, the cylindrical portion of the rotating frame that enters the skirt portion is also in contact with the inner peripheral surface of the skirt portion. Are formed in a cylindrical shape so as to make the gap between them as small as possible. For this reason, if the diameter of the skirt portion of the spool is increased, the diameter of the cylindrical portion of the rotating frame must be increased, and there is a problem that the weight of the spool, the rotating frame and the like increases, and the reel becomes heavier. In addition, when the diameter of the skirt portion of the spool is increased, the moment of inertia of the rotating portion such as the rotating frame is increased, and a problem arises in that the initial power of the handle (starting force of winding) increases. In addition, if the diameter of the skirt portion of the spool is large, the root of the arm of the rotating frame is correspondingly large, and the root of the arm of the rotating frame is present as a protrusion around the reel, and it is difficult to operate the reel. There is a problem of becoming an obstacle.

Accordingly, an object of the present invention is to provide means for solving such a problem.

[0006]

A spool shaft (6) is attached to the front of the reel body (1) so as to be able to reciprocate back and forth on the rotation center of the rotating frame (3) in conjunction with the operation of the arm (30) and the handle (2). In the spinning reel for fishing provided with the spool (4) supported through the skirt (35) of the spool (4) covering the cylindrical portion (25) of the rotating frame (3), the rear end is larger than the front end. Is formed to have a smaller diameter, and the pair of arms (2 , 27) such that the arms (26, 27) are inclined so that the distance (a, b) between the inner surface (26a, 27a) facing the skirt portion (35) and the skirt portion 35 is substantially the same in the front and rear. Adopt a fishing spinning reel.

According to a second aspect of the present invention, the pair of arms (26, 27) has an outer surface (26) opposite to the inner surfaces (26a, 27a) facing the skirt portion (35).
b, 27b) are formed so as to be substantially parallel to each other.

According to a third aspect of the present invention, a cavity (37) is formed in at least one arm (26) of the pair of arms (26, 27) so as to extend in a direction in which the arm (26) is inclined. A reversing mechanism (40) for selectively holding the bail arm (30) in one of two positions, a fishing line release position and a fishing line winding position, is housed in the cavity (37). The spinning reel for fishing described in Item 2 is adopted.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

Embodiment 1 As shown in FIG. 1, this fishing spinning reel has a handle 2 on a side surface of a reel body 1 and a rotating frame 3 and a spool 4 on a front portion of the reel body 1. It is supported by a fishing rod (not shown) via a leg 5 provided on the upper part of the reel body 1.

The spool 4 is fixed to the tip of a spool shaft 6, and the spool shaft 6 is provided on the reel body 1 so as to be able to reciprocate in the front-rear direction of the reel. The longitudinal movement of the spool shaft 6 is caused by the rotational movement of the handle 2 being converted to a linear movement via a sliding mechanism described later.

The sliding mechanism includes an oscillating gear 9 to which a rotational force is transmitted via a gear 8 from a handle shaft 7 rotatably supported by the reel body 1, a pin 10 provided on a side surface of the oscillating gear 9, Vertical groove 11 into which the pin 10 is inserted
And an oscillator 12 attached to the rear end of the spool shaft 6 having the above. When the handle 2 is operated to rotate the handle shaft 7, the oscillation gear 9 rotates in conjunction with the rotation, and the pin 10 slides in the vertical groove 11 of the oscillator 12 to move the oscillator 12 in the front-rear direction. And As a result, the spool 4 reciprocates back and forth on the rotation center of the rotating frame 3 together with the spool shaft 6.

A drag mechanism 13 is provided between the spool 4 and the spool shaft 6. Drag mechanism 13
The first and second brake disks 14 and 15 put on the spool shaft 6 are pressed against the inner wall of the spool 4 by a knob 16 attached to the tip of the spool shaft 6. The first and second brake discs 14 and 15 each have a non-circular cross section on the spool shaft 6,
It is locked so as not to turn in the vertical groove on the side. Knob 1
6, a drag nut 17 screwed to the tip of the spool shaft 6 is provided so as to be able to move back and forth in the knob 16 in a detented state, and is interposed between the drag nut 17 and the rear end wall of the knob. To the first and second brake discs 14, 15
A spring 18 is provided to urge the superimposed body of. Therefore, the spool 4 is fixed on the spool shaft 6 by a frictional force generated between the first and second brake disks 14 and 15, and when a force overcoming this frictional force is applied to the spool 4 by the fishing line, the spool 4 It rotates on the spool shaft 6. This frictional force can be adjusted by turning the knob 13 to cause the drag nut 17 in the knob 16 to advance and retreat on the spool shaft 6.

The knob 13 is provided with a ringer 19 for generating a sound when the knob 13 is turned. That is,
A hollow is provided in the knob 13 so as to surround the tip of the spool shaft 6, teeth are carved on the inner periphery of the hollow, and a ring 21 and a ring 19 are provided at the tip of the spool via a disk 21.
And a spring 20 for urging the teeth toward the teeth. The disk 21 is held by the non-circular section of the spool shaft 6 in a transverse cross section. For this reason, when the knob 13 rotates on the spool shaft 6, the teeth in the knob 13 hit the ringer 19, which is stationary on the spool shaft 6 via the disk 21, and generates a clicking sound.

The rotating frame 3 rotates around the spool 4 by transmitting the rotating force of the handle 2. That is, a master gear 22 is attached to the shaft 7 of the handle 2, and the cylindrical pinion 2 meshing with the master gear 22 is provided.
3 is rotatably supported at the front of the reel body 1 via a bearing 24. The spool shaft 6 penetrates the center hole of the pinion 23 slidably in the front-rear direction. Thus, the rotation of the handle 2 is transmitted to the rotating frame 3 via the master gear 22 and the pinion 23, and the rotating frame 3 rotates around the spool 4 that moves back and forth.

The rotating frame 3 is connected to the pinion 23 and has a cylindrical body 25 that rotates around the spool shaft 6 together with the pinion 23.
A pair of arms 26, 27 extending forward from the rear edge of the cylindrical body 25, a bail arm lever 28 attached to the tip of one arm 26, and attached to the tip of the other arm 27. The vehicle includes a bail arm holder 29, a bail arm lever 28, and a bail arm 30, both ends of which are supported by the bail arm holder 29.

The cylinder 25 is disposed so as to cover the front part of the reel body 1 and is connected to the bail arm 3 from the arms 26 and 27.
It is rotatable around the spool 4 while holding the portion reaching zero. The bail arm lever 28 and the bail arm holder 29 are rotatably supported by the arms 26 and 27 via pins 31 respectively, and the bail arm 30 is rotatable about these pins 31 as fulcrums. A bail arm 30 is provided between the bail arm 30 and the bail arm lever 28.
There is provided a bail arm roller 32 that can rotate while being in contact with the fishing line while being supported by the bail.

With such a structure of the rotating frame 3, the bail arm 30 can be switched between a fishing line winding position and a fishing line releasing position. When the rotating frame 3 is rotated after turning the bail arm roller 32 to the fishing line winding position with the two pins 31 as fulcrums, the bail arm roller is attached to the fishing line winding portion of the spool 4 that slides back and forth in the front-rear direction. 32 winds the fishing line. When the bail arm roller 32 is switched to the fishing line release position, the fishing line wound on the fishing line winding portion of the spool 4 can be discharged to the front of the spool 4.

In addition, between the rotating frame 3 and the reel body 1, a reverse rotation preventing mechanism for regulating the rotating direction of the rotating frame 3 is provided. The reverse rotation preventing mechanism includes a ratchet tooth 33 provided on the inner peripheral surface of the cylindrical body 25 of the rotating frame 3, a claw (not shown) that is rotatably attached to the reel body 1 and meshes with the ratchet tooth 33. And an anti-lever 34 for engaging and disengaging the pawl with respect to the ratchet teeth 33. Anti-lever 34
Is disposed outside the reel body 1, and an anti-lever shaft integrated with the anti-lever 34 penetrates the reel body 1 back and forth in parallel with the spool shaft 6. The tip of the anti-lever shaft is connected to the pawl by a link (not shown). The anti-lever shaft is rotatable on the reel body 1 by operating the anti-lever 34. Turning the anti-lever shaft to one side engages the pawl with the ratchet teeth 33, and turning the anti-lever shaft to the other side releases the pawl from the ratchet teeth 33. It has become.
When the anti-lever 34 is turned on and the pawl is engaged with the ratchet teeth 33, the rotating frame 3 is rotatable only in the fishing line winding direction. When the anti-lever 34 is turned off and the pawl is separated from the ratchet teeth 33, the rotating frame 3 is turned on. In both the winding direction and the feeding direction.

At the rear of the spool 4, a skirt 3
5 are provided. The skirt portion 35 enters between the cylinder 25 of the rotating frame 3 and the arms 26 and 27 and surrounds the cylindrical body 25 so as to prevent the fishing line from being caught in the rotating frame 3. The skirt portion 35 is formed in a truncated conical shape such that the rear end has a smaller diameter than the front end. For this reason, the weight of the skirt portion 35 is reduced as compared with the case of the cylindrical shape. Further, as the rear end of the skirt portion 35 is narrowed, the cylindrical body 25 of the rotating frame 3 is also formed to have a smaller diameter. For this reason, the rotating frame 3 is reduced in weight, the moment of inertia is also reduced, and the initial power required to start winding the fishing line is kept low.

A pair of arms 26 and 27 of the rotary frame 3 are provided.
As shown in FIG. 1 and FIG.
5 corresponds to the inclination of 5. A pair of arms 26 and 27
Is preferably the same as the degree of inclination of the skirt portion 35, and the distances a and b between the skirt portion 35 and the skirt portion 35 are the same before and after (a = b) or substantially the same (a
≒ b).

The pair of arms 26 and 27 are respectively provided with an arm body 36 integrally formed with the rotating frame 3 and the arm body 3.
6. A cavity 37 formed on a surface opposite to the cylindrical body 25.
And a cover 38 fixed to the arm body 36 covering the cavity 37 with fixing screws. Each of the arms 26, 27 is formed such that the inner surfaces 26a, 27a facing the skirt portion 35 and the outer surfaces 26b, 27b on the opposite side are substantially parallel.
For this reason, the conventional projection 39 shown by the broken line in FIG. 1 is eliminated, which is convenient for reel operation. Also, the moment of inertia is reduced, and the initial power is also reduced.

In the pair of arms 26 and 27, the cavities 37 extend in the direction of inclination of the arms 26 and 27, and as shown in FIGS. A reversing mechanism for selectively holding 30 at one of two positions, a fishing line discharge position and a fishing line winding position, is housed.

The reversing mechanism 40 includes a guide groove 41 formed substantially along the length of the arm body 36, a slider 42 inserted in the guide groove 41, and the slider 42 Point spring 4 biasing toward
3, the slider 42 and the bail arm lever 28
And a kick lever 45 which is connected to the boss 28a of the bail arm lever 28 by pin connection.

The connecting link 44 is connected to the bail arm lever 28.
4 is urged toward the pin 31 by the dead point spring 43 via the slider 42 so that the bail arm lever 28 moves around the pin 31 in FIG. When rotated clockwise, the link 44 reverses from the position indicated by the solid line to the position indicated by the alternate long and two short dashes line, and stops at that position. This corresponds to the case where the bail arm 30 has moved to the fishing line discharge position. Conversely, when the bail arm lever 28 is rotated counterclockwise around the pin 31, the connecting link 44 is reversed from the position indicated by the two-dot chain line to the position indicated by the solid line, and the bail arm 30 returns to the position indicated by the solid line. I do. This corresponds to the case where the bail arm 30 has moved to the fishing line winding position. Slider 4 above
2 makes contact with the wall of the guide groove 41 at the beginning and end of the switching of the bail arm 30 and emits a sound, so that the angler can confirm the switching of the bail arm 30. In this case, a projection 46 is formed on the boss 28a of the bail arm lever 28 in order to accurately stop the bail arm 30 so that the fishing line can be properly wound by the bail arm 30, and a stopper 47 with which the projection 46 abuts is provided. Arm body 3
It is provided on the 6 side.

One end of the kick lever 45 is pin-connected to the boss 28a of the bail arm lever 28, and the other end thereof passes through holes (not shown) formed in the arm body 36 and the cylindrical body 25 toward the reel body 1. I have. Kick lever 45 is arm 36
When the bail arm 30 is inverted to the fishing line releasing position and the connecting link 44 comes to the position indicated by the two-dot chain line, the kick lever 45 is formed at the front portion of the reel body 1. It comes to face the projection that does not. When the handle 2 is operated while the bail arm 30 is stopped at the fishing line release position and the rotating frame 3 rotates, the other end of the kick lever 45 collides with the protrusion on the front part of the reel body 1 and is pushed toward the pin 31. Therefore, the boss 28a of the bail arm lever 28 is pushed counterclockwise around the pin 31 in FIG. As a result, the connecting link 44 moves over the dead point to the opposite side, moves from the position indicated by the two-dot chain line to the position indicated by the solid line, and the bail arm 30 reverses to the fishing line winding position and stops.

Next, a series of movements of the fishing spinning reel will be described.

It is assumed that the bail arm 30 is set at a fishing line winding position shown by a solid line in FIGS. As shown in FIG. 4, when the connecting link 44 of the reversing mechanism 40 is at the solid line position and receives the urging force of the dead point spring, the bail arm lever 28 tries to rotate counterclockwise around the pin 31 and The lever 28 has a projection 46 of the boss 28 a provided with a stopper 47 toward the arm 26.
Stops at the position indicated by the solid line. The kick lever 45 is stopped at the position indicated by the two-dot chain line.

Then, when the operator turns the handle 2, the oscillating gear 9 rotates and the pin 10 of the oscillating gear 9 is rotated.
Moves in the vertical groove 11 of the oscillator 12,
The oscillator 12 reciprocally slides with the spool shaft 6 in the front-rear direction of the reel. The spool 4 fixed to the tip of the spool shaft 6 makes a reciprocating linear movement in front of the reel body 1 by the stroke of the oscillator 12.

On the other hand, the rotating frame 3 rotates around the spool 4 simultaneously with the reciprocating movement of the spool 4 and winds the fishing line on the spool 4 moving back and forth. The cylindrical body 25 of the rotating frame 3
The base of the pair of arms 26 and 27 has a small diameter with respect to the center of rotation of the rotating frame 3 because the skirt portion 35 of the spool 4 has a narrowed skirt portion, has a small moment of inertia, and therefore has a relatively small initial power. The rotating frame 3 can be turned.

Next, when the bail arm 30 in the fishing line winding state is pushed to the fishing line release position, the bail arm lever 28
And the bail arm holder 29 rotates clockwise around the pin 31 in FIG. At that time, as shown in FIG. 4, the connecting link 44 rotates over the connecting line between the pin 31 and the slider 42 to the position indicated by the two-dot chain line, and stops at the position by the urging force of the dead point spring 43. I do. As a result, the bail arm 30 is held at the fishing line release position, and the fishing line can be paid out from the spool 4.

On the other hand, at the same time as the rotation of the bail arm lever 28, the kick lever 45 also moves rightward from the position indicated by the two-dot chain line in FIG. The operation stops at the position. When the handle 2 is turned in this fishing line releasing state, the kick lever 45 also rotates integrally with the rotating frame 3, and the rear end thereof comes into contact with the projection of the reel body 1. As a result, the kick lever 45 attempts to return to the original position indicated by the two-dot chain line, and turns the bail arm lever 28 counterclockwise around the pin 31 in FIG. When the bail arm lever 28 rotates counterclockwise, the connecting link 44 moves from the position indicated by the two-dot chain line to the position indicated by the solid line, and the urging force of the dead point spring 43 and the contact of the projection 46 against the stopper 47 are performed. The posture is maintained by contact.

As described above, the spool base cylinder 48 includes
The spool cylinder 52 is detachably attached by the positioning means, and an O-ring 64 is fitted around the tip of the spool shaft 6 for adjusting the friction braking force of the above-described drag mechanism, as shown in FIG. A combined drag adjustment knob 16 is attached. The O-ring 64 contacts the inner peripheral surface of the spool ring screw 59 to prevent water and dust from entering the drag mechanism 13.

The knob 16 has the drag nut 17 at the center. A central hole 66 into which the fixture 65 is inserted is formed in the center of the knob 16. The fixing tool 65 is formed in a cylindrical shape, and is relatively rotatably inserted into the center hole 66. The fixing tool 65 can be screwed to the tip of the spool shaft 6. For this reason, the knob 16 is rotatable about a fixture 65 fixed to the tip of the spool shaft 6. Knob 1
The disk 21 is rotatably arranged in the center hole 66 of the sixth. The disk 21 has a through hole having a shape corresponding to a non-circular portion in the cross section at the tip of the spool shaft 6. A plurality of recesses are formed on the back surface of the disk 21 at predetermined intervals in the circumferential direction. The disk 21 has a cover 67 fixed to the back surface of the knob 16 by screws 19.
Thus, the knob 16 is rotatably held in the knob 16. The rear end of the cover 67 is a nut receiver for receiving the drag nut 17 so as to be able to rotate integrally with the drag nut 17. A click mechanism is arranged on the cover 67. That is, the cover 67 is formed with a hole that opens in front of the cover 67, and the contact 19 is disposed in the hole so as to be able to protrude and retract. The contact 19 is urged by a coil spring 20 disposed in the hole such that its tip projects forward of the cover 67 and resiliently engages with any one of the recesses of the disk 21. ing.

The above-described assembly comprising the knob 16, the disk 21, the fixture 65, and the cover 67 inserts the non-circular cross-section at the tip of the spool shaft 6 into the non-circular through-hole of the disc 21, and While turning 65, the spool shaft 6 is screwed into the tip of the spool shaft 6, and the drag nut 17 is fitted into the nut receiver of the cover 67.
Attach to the tip.

The knob 16 attached in this manner
Rotates integrally with the drag nut 17 around the fixture 65 and the disk 21, so that the amount of screwing of the drag nut 17 is adjusted by rotating the knob 16, whereby the pressing force of the drag spring 56 is adjusted. As a result, the braking force of the spool base cylinder 48 against the spool receiver 49, that is, the drag set value is adjusted.

When the knob 16 is rotated, the contact 19 of the click mechanism is resiliently engaged with the plurality of recesses of the disk 21 sequentially, and generates a click sound. The clicker can confirm the degree of drag adjustment by the knob 16 with the click sound.

Next, the operation of removing the spool in the fishing spinning reel incorporating the spool attaching / detaching mechanism will be described.

To replace the spool 4, the spool cylinder 5
2, first, fix the fixture 65 to the spool shaft 6.
On the screw at the end of the screw in the direction opposite to the mounting direction. Accordingly, the knob 16 is attached to the cover 67 and the disk 21.
And comes off the spool shaft 6 integrally with the disk 21
Is disengaged from the non-circular cross section of the spool shaft 6, and the cover 6
Numeral 7 slides on the outer periphery of the drag nut 17 without turning the drag nut 17 and comes out of the spool cylinder 52.

After the assembly consisting of the knob 16, the disk 21, and the cover 67 is removed from the spool 4, the spool cylinder 52 is moved against the urging force of the coil spring 53 of the click mechanism provided on the spool 4. When rotated in a direction opposite to the fishing line winding direction, the engagement between the contact 53 of the click mechanism and the concave portion 54 of the spool base cylinder 48 is released, and the spool cylinder 52 is easily removed from the spool base cylinder 48. Since the drag nut 17 does not rotate when the spool cylinder 52 is removed, the drag set value does not change.

In order to attach the detached spool tube 52 or another spool tube to the spool base tube 48, the reverse operation of the above-described removal operation of the spool tube 52, the reverse operation of the above-described removal operation of the assembly, and the fixing are performed. The operation reverse to the above-described removal operation of the tool 65 is performed.

Fifth Embodiment As shown in FIG. 12, the skirt 35 of the spool 4 in the fifth embodiment is cylindrical, unlike the skirt 35 of the fourth embodiment, and the cylindrical shape of the spool cylinder 52 is different from that of the fourth embodiment. The portion 58 is connected to the portion 58 via a step, and the diameter is reduced by the step. Correspondingly, the diameter of the cylindrical portion 25 of the rotating frame 3 is also reduced.

The pair of arms 26 and 27 are closest to the skirt 35 at their front and rear ends, and are inclined so that the distances a and b between them are the same or substantially the same.

As shown in FIGS. 12 and 13, the arms 26, 27

[0067]

According to the present invention, in the spinning reel for fishing, the skirt portion of the spool covering the cylindrical portion of the rotating frame is formed so that the rear end thereof has a smaller diameter than the front end thereof. Arm is tilted so that the distance between the arm and the skirt portion is substantially the same in the front and rear directions, so that the diameter of the skirt portion of the spool and the cylindrical portion of the rotating frame can be reduced to reduce the weight of the reel. At the same time, by bringing the vicinity of the base of the arm of the rotating frame closer to the center of rotation of the rotating frame, the moment of inertia of the rotating frame can be reduced and the initial power of the steering wheel (starting force of winding) can be reduced. Further, since the base of the arm of the rotating frame approaches the center of rotation of the rotating frame, the amount of protrusion near the base of the arm of the rotating frame is reduced, and the reel is accordingly made more compact.
Also, despite the fact that the root of the arm of the rotating frame approaches the center of rotation of the rotating frame, it is possible to increase the spool diameter of the spool,
The yarn winding amount can be increased, and the occurrence of yarn habit and yarn twist can be prevented.

In the present invention, when the pair of arms is formed so that the inner surface facing the skirt portion and the outer surface on the opposite side are substantially parallel, the outer shape of the arms is reduced.

In the present invention, when a cavity is formed in at least one arm of the pair of arms and extends in the inclined direction of the arm, a space for accommodating the bail arm reversing mechanism can be secured.
