DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a yarn twist preventing mechanism,
In particular, the present invention relates to a thread twist removing mechanism disposed between a spool of a spinning reel and a spool shaft.

[0002]

2. Description of the Related Art In general, a spinning reel generally has a reel body, a spool shaft supported on the reel body so as to be movable back and forth, a spool mounted on the spool shaft, and a reel body rotatable around the spool shaft. And a drag mechanism for rotating the spool when a sharp load is applied to the fishing line.

In this type of spinning reel, for example, when a yarn is unwound from a spool fixed during casting, the yarn is twisted, and is removed to some extent when the yarn is wound around the spool. However, in practice, the twisting occurs due to the rotation of the tackle in the sea due to the tide, the rotation of the spool when a force greater than the force set by the drag mechanism acts on the fishing line, and the like. If such twisting of the thread becomes remarkable, the thread may become entangled with the reel or the guide of the rod or cause the device to rotate during casting.

[0004] As a prior art for removing this twisting, there is known a spinning reel in which a spool is integrally rotated together with a rotor in a yarn feeding direction (Japanese Patent Laid-Open No. 4-65).
650 etc.). The spinning reel includes a spool having a thread winding portion and a skirt portion, which is rotatably supported on a spool shaft only in a thread payout direction via a one-way clutch, and a cylindrical portion and a cylindrical portion arranged on the inner peripheral side of the skirt portion. A rotor having a cylindrical portion and a disk portion integrally formed on the inner peripheral side of the portion, an engagement / disengagement mechanism for rotating the spool and the rotor integrally, and a rear drag mechanism for braking the rotation of the spool are provided. ing.

The engagement / disengagement mechanism has a projection formed on the inner peripheral surface of the skirt portion so as to extend in the axial direction, and is capable of moving forward and backward with respect to the outer peripheral surface of the cylindrical portion of the rotor, and is capable of engaging with the convex portion at the time of advance. And a switching lever for moving the spool reverse rotation claw forward and backward. The spool reversing claw is fixed to the front end of the switching shaft rotatably supported by the disk portion through the disk portion of the rotor. The switching lever is fixed to the rear end of the switching shaft, and protrudes outward from the cylindrical portion behind the skirt portion.

In this spinning reel, when the spool reversing claw is advanced by the switching lever, the spool reversing claw is locked to the convex portion, and the spool can be reversely rotated integrally with the rotor. Therefore, if the rotor is rotated in reverse by the handle after performing such a lever operation, the spool also follows the rotor and rotates integrally with the rotor, so that even if a twist occurs, it can be easily removed.

[0007]

In the conventional spinning reel, element members constituting an engaging / disengaging mechanism such as a switching shaft, a spool reversing claw, and a switching lever are unbalanced on a disk portion of a high-speed rotating rotor. Therefore, the dynamic balance of the rotor is likely to be lost. If the dynamic balance of the rotor is lost, the rotor will run out of rotation when the rotor rotates during winding of the yarn, and the rotor will not rotate smoothly.

An object of the present invention is to make it possible to reverse the rotor and the spool integrally without breaking the dynamic balance of the rotor.

The step 67 is slightly raised from the front side surface, and the outer peripheral side is slightly smaller than the cylindrical portion 63. At one end in the circumferential direction of the step portion 67, a convex portion 67a having a rounded tip is formed, and at the other end, a shoulder portion 67b extending in the radial direction is formed. A deformed groove 67c is formed between the protrusion 67a and the shoulder 67b of the adjacent step 67. The projection 67a is for setting a locking pin (described later) in a locking posture. Note that, as shown in FIG. 4, the deformable groove 67c is disposed to face the inclined surface 66b of the inclined cam 66. As described above, by arranging the deformable groove 67c in relation to the inclined cam 66, the swing of the first engagement / disengagement section 60 to the locking posture and the movement of the second engagement / disengagement section 61 to the disengagement position are simultaneously performed. I can do it.

The first engaging / disengaging portion 60 has a locking pin 70 rotatably disposed in the support groove 56 in the skirt portion 4b. The locking pin 70 has a shape in which both ends of, for example, a stainless steel wire are bent 90 degrees so as to form an angle of about 105 degrees with each other, as shown in an enlarged view in FIG. It has a locking portion 70b on the rear end side bent at 90 degrees from both ends of the support portion 70a and an operating portion 70c on the front end side.

The locking pin 70 is provided at the center of the support portion 7.
Reference numeral 0a is rotatably supported by a square hole formed by the connecting piece 56a of the support groove 56 and the outer peripheral surface of the cylindrical portion 63. The locking pin 70 has a locking position in which the locking portion 70b stands up in the radial direction at the rear end portion 56b of the support groove 56 as shown by a solid line in FIG. 5, and a rear end portion as shown by a two-dot chain line. The locking portion 70b swings between the detached posture arranged in the circumferential direction within the 56b. When the locking pin 70 is in the locking position,
Locked to either the first arm 31 or the second arm 32 of the rotor 4 (FIG. 1). At this time, the operation unit 70c
As shown by a solid line in FIG.
It is arranged in a space formed between c and the outer peripheral surface of the step portion 67 of the operation portion 62. Further, when in the detached posture, the operation section 70c is arranged in a space inside the deformable groove 67c as shown by a two-dot chain line.

In the first engaging / disengaging portion 60 configured as described above, when the operating portion 62 is rotated with respect to the spool 4 in the line payout direction (counterclockwise in FIG. 4), the operating portion 70c is moved into the deformed groove 67c. The locking pin 70 in the detached position is pushed in contact with the convex portion 67a of the second member and swings counterclockwise. When the operating portion 70c is disposed in the space formed between the distal end portion 56c of the support groove 56 and the outer peripheral surface of the step portion 67 of the operation portion 62, the locking portion 70b stands up and assumes the locking posture. .

The spool 4 rotates forward following the rotor 3. At this time,
Since the locking pin 70 attempts to rotate clockwise due to the pressing force from the rotor 3, the operating portion 70c rotates integrally with the spool 4 while contacting the outer peripheral surface of the stepped portion 67, and the convex portion in the deformed groove 67c. The operation part 70c is guided by the part 67a and is housed in the deformation groove 67c. As a result, when the operation part 70c of the locking pin 70 reaches the deformation groove 67c, the locking pin 70 swings to the detached posture.

The drag washer 91c is rotatably supported on the spool shaft 8 and can move back and forth, and its outer periphery is locked in a locking groove 80d formed on the inner circumferential surface of the drag case 80. And cannot rotate. The other drag washers 91b, 91d, 91f are supported by the spool shaft 8 so as to be rotatable and movable back and forth.

[Reel Operation and Operation] At the time of casting, the bail 43 is moved down to the line releasing position. By swinging the fishing rod, the fishing line wound around the outer periphery of the spool 4 is released. At this time, each time the fishing line is wound around the spool 4 once, the spool 4 has a single twist of the fishing line. When the fishing line is released, the twist of the fishing line is cancelled and the spool 4 is fed out.

At the time of winding the fishing line, the bail 43 is tilted to the line winding position. When the handle 1 is rotated forward in this state, the torque is applied to the handle shaft 10 and the face gear 11.
Through the pinion gear 12. The torque transmitted to the pinion gear 12 is applied to the pinion gear front portion 12.
The rotation is transmitted to the rotor 3 via a, and the rotor 3 rotates forward. On the other hand, the screw shaft 21 is rotated by the intermediate gear 23 meshing with the pinion gear 12, and the slider 22 meshing with the groove 21a of the screw shaft 21 is guided by the guide shaft and moves in the front-back direction. For this reason, the spool line 8 and the spool 4 reciprocate in the front-rear direction along the rotation axis X, and the fishing line guided to the spool 4 by the bail 43 and the line roller 41 is
The spool 4 is uniformly wound around the outer periphery in the front-rear direction. At this time, the fishing line that has been fed out while being twisted in a direction opposite to the direction in which the fishing line is wound around the spool 4 during casting is removed. Further, since the engagement / disengagement mechanism 7 is provided on the non-rotating spool 4, the dynamic balance is maintained, and the rotational fluctuation of the rotor 3 is less likely to occur.

When the fish is applied and the pulling force is larger than the drag force of the drag mechanism 9, the spool 4 rotates in the line pay-out direction against the drag force of the drag mechanism 9. At this time,
Unless the spool 4 is rotated in the line feeding direction by permitting the reverse rotation of the rotor 3 by the operation mechanism 52, the yarn twist does not occur. However, the operation mechanism 52 causes the rotor 3
Is in the reverse rotation prohibited state, the spool 4 rotates in the line reel-out direction as described above, and the yarn is significantly twisted. Leaving such a twist causes inconveniences such as the fishing line getting entangled with the reel during casting.

When such yarn twisting occurs remarkably, the operating section 62 is rotated with respect to the spool 4 in the yarn feeding direction (clockwise in FIG. 4). Then, the locking pin 7
0 is pushed by the convex portion 67a to stand up in the locking posture, and the highly flat surfaces 66a, 86a of the inclined cams 66, 86 are opposed to each other, and the clutch cam 81 advances to the disengagement position. When the locking pin 70 rises to the locking position, the locking pin 70 can be locked to the first arm 31 or the second arm 32 of the rotor 3. When the clutch cam 81 advances to the disengagement position, the uneven portion 55 formed on the inner peripheral surface of the spool 4 changes from a state facing the locking groove 88 to a state facing the separation groove 87, and the spool 4 rotates. Be free. In this state, when the reverse rotation preventing mechanism 50 of the rotor 3 is operated in the reverse rotatable state to rotate the rotor 3 reversely by the handle 1, the locking pin 7
