  In the conventional spinning reel rotor braking device, the rotating member is braked by being sandwiched between the moving brake shoe and the fixed pressure contact piece. For this reason, the force which inclines a rotation member at the time of braking acts on a rotation member. This tilting force increases as the braking force increases. As a result, even if the brake lever is operated strongly, the braking force does not increase efficiently.

  An object of the present invention is to enable a braking force to be efficiently increased in accordance with an operation by a braking operation unit in a spinning reel rotor braking device.

  In this braking device, when the rotor rotates in the yarn feeding direction, the rotation is transmitted to the rotating member via the one-way clutch. On the other hand, when the rotor rotates in the yarn winding direction, the rotation is not transmitted to the rotating member. If the braking operation unit is moved by the first operation unit while the rotor is rotating in the yarn take-out direction, the first braking action unit of the braking operation unit contacts any one of the braking surfaces. At the same time, the second braking action part of the interlocking mechanism contacts the other of the braking surfaces in conjunction with the braking operation part, and the braking part is clamped by both braking action parts, and the rotating member is braked. Here, the two braking surfaces of the braking portion of the rotating member are sandwiched and braked between the first braking action portion of the braking operation portion that moves in conjunction with the second braking member of the interlocking mechanism, so the braking portion is tilted. It becomes difficult for force to act. For this reason, it becomes possible to increase the braking force efficiently according to the operation by the braking operation unit.

  A spinning reel rotor braking device according to a second aspect of the present invention is the device according to the first aspect, wherein the braking portion has a cylindrical shape and has braking surfaces on an outer peripheral surface and an inner peripheral surface thereof.

As a result, as shown in FIG. 6, the second cylindrical portion 38 b is sandwiched between the first brake shoe 51, the rotating member 22 is braked, and the rotation of the rotor 3 in the yarn unwinding direction is braked. In addition, when the finger is released from the brake lever 50 and the brake lever 50 returns to the brake release position, the pressing by the second brake shoe 53 is released.

  Here, the two braking surfaces 38e and 38f of the second cylindrical portion 38b of the rotating member 22 are sandwiched between the first brake shoe 51 of the braking lever 50 that moves in conjunction with the second brake shoe 53 of the interlocking mechanism 24. Therefore, the force that tilts the rotating member 22 is less likely to act. For this reason, the braking force can be increased efficiently according to the operation by the braking lever 50.

[Configuration of the first predetermined braking section]
As shown in FIGS. 3, 5, and 8, the first predetermined braking unit 25 includes a friction member 63 that is rotatably mounted on the inner peripheral surface of the braking member 38 and frictionally engages the braking member 38, and a friction member 63 has a switching operation unit 60 that can be engaged and disengaged. The switching operation unit 60 engages with the friction member 63 to prohibit the rotation of the friction member 63 in the yarn unwinding direction, and rotates the friction member 63 relative to the rotation member 22 to brake the rotation of the rotor 3 in the yarn unwinding direction. and that dynamic braking position to, and is attached to be switchable reel body and separate position to allow releasing braking rotation of the friction member 63 away from the friction member 63. Specifically, the switching operation unit 60 includes a lever member 61 that swings in conjunction with the brake lever 50, and a toggle spring 62 that holds the lever member 61 at a brake release position (separation position) and a predetermined brake position. Have.

  As shown in FIGS. 3 and 8, the lever member 61 is swingably mounted on a swinging shaft 65 disposed in parallel to the spool shaft 8 at the mounting portion of the mounting member 2 e of the reel body 2. The distance from the base end of the lever member 61 to the swing center is at least twice as long as the distance from the tip to the swing center. The distal end of the lever member 61 is locked in the locking recess 50e, and the lever member 61 swings between the braking release position (FIG. 8) and the predetermined braking position (FIG. 9) in conjunction with the braking lever 50. Move. A locking claw 70 is swingably attached to the intermediate portion of the lever member 61. The locking claw 70 has a spring locking portion 70a at the base end and an acute-angle claw portion 70b at the tip, and in a direction in which the claw portion 70b protrudes by the coil spring 71 (counterclockwise in FIG. 8). It is energized. A toggle spring 62 is locked to the base end of the lever member 61. A positioning member 66 that contacts the braking surface 38e and positions the swinging position of the lever member 61 at the first predetermined braking position is provided between the swinging center of the lever member 61 and the mounting portion of the locking claw 70. It is installed. The positioning member 66 is provided to maintain a constant distance between the lever member 61 and a ratchet tooth 63a of a friction member 63 described later.

  Here, when in the brake release position, the lever member 61 is biased by the toggle spring 62 and the tip contacts the upper surface of the locking recess 50e. Further, when in the first predetermined braking position, the tip contacts the lower surface of the locking recess 50e. One end of the coil spring 71 is locked to the spring locking portion 70 a and the other end is locked to the swing shaft 65 of the lever member 61. In this way, the latching claw 70 is swingably mounted on the lever member 61 and is biased in the direction in which the claw portion 70b protrudes by the coil spring 71, whereby the lever member 61 swings to the first predetermined braking position. Sometimes even if the claw portion 70b comes into contact with the protruding portion of the second ratchet tooth 63a because the rotational phase of the claw portion 70b and the second ratchet tooth 63a (described later) of the friction member 63 does not match, the shock is absorbed. The friction member 63 can be reliably prevented from rotating.

  As shown in FIGS. 5 and 8, the friction member 63 is a cylindrical member and is rotatably mounted on the inner periphery of the first cylindrical portion 38 a of the braking member 38. On the inner peripheral surface of one end (right end in FIG. 5) of the friction member 63, a sawtooth-shaped second ratchet tooth 63a that engages with the claw portion 70b of the locking claw 70 is formed so as to protrude radially inward. The second ratchet teeth 63a are provided to engage the locking claws 70 and prohibit the rotation of the friction member 63 in the yarn unwinding direction when the lever member 61 is in the predetermined braking position (FIG. 9). On the outer peripheral surface of the friction member 63, at least one (for example, two) annular mounting grooves 63b are formed. A friction ring 64 that frictionally engages the first cylindrical portion 38a and the friction member 63 is mounted in the annular mounting groove 63b. The friction ring 64 is at least one (for example, two) ring made of, for example, an O-ring, which is mounted to frictionally engage the friction member 63 with the braking member 38.

  Washers 73a and 73b are disposed at both ends of the friction member 63, respectively. The washer member 73a is disposed in the gap between the disc member 37 and the friction member 63, and the washer member 73b is disposed between the friction member 63 and the step portions of the first and second cylindrical portions 38a and 38b. Yes. These washer members 73a and 73b are provided so that the friction member 63 does not rattle by adjusting the axial mounting dimension of the friction member 63.

  In the friction member 63 configured as described above, when the lever member 61 is disposed at a predetermined braking position and the locking claw 70 is engaged with the second ratchet teeth 63a, the friction member 63 is prohibited from rotating in the yarn unwinding direction. The ring 64 frictionally slides against the braking member 38 by the action of the ring 64, and brakes the braking member 38 in the first predetermined braking state.

  Here, when the brake lever 50 is pushed into the predetermined braking position, the lever member 61 also swings from the braking release position to the first predetermined braking position in conjunction with the operation. As a result, the engaging claw 70 engages with the second ratchet teeth 63a of the friction member 63, and the rotation of the rotor 3 in the yarn unwinding direction is braked in the first predetermined braking state.

  As shown in FIGS. 8 and 9, the toggle spring 62 can urge the lever member 61 to urge the braking lever 50 to a predetermined braking position and a braking release position, thereby maintaining the posture. The toggle spring 62 is a torsion coil spring attached to the base end of the lever member 61. One end of the toggle spring 62 is locked to the base end of the lever member 61, and the other end is locked to the front end surface of the housing portion 2f. As shown in FIG. 8, the toggle spring 62 urges the lever member 61 in the clockwise direction of FIG. 9 when the lever member 61 is arranged at the braking release position, and when the lever member 61 is arranged at the predetermined braking position, as shown in FIG. Energize counterclockwise. As a result, the lever member 61 is held at the brake release position and the predetermined brake position, and the brake lever 50 is held at the brake release position and the predetermined brake position.

[Configuration of second predetermined braking section]
As shown in FIGS. 2 and 3, the second predetermined braking unit 26 includes a moving member 75 mounted on the front surface of the housing 2 f and a switching operation unit 76 for switching the moving member 75. ing. The moving member 75 is made of, for example, a synthetic resin having elasticity such as a polyamide-based synthetic resin or polyacetal, and has a third brake shoe (an example of a third braking action portion) 75a capable of pressing the braking surface 38e at the tip. ing. In addition, a switching protrusion 75 b that engages with the switching operation portion 76 is provided at the base end. The moving member 75 is guided to the front surface of the housing portion 2f so as to be movable between a braking position that can be pressed by contact with the braking surface 38e and a braking release position that is separated from the braking surface 38e, and is prevented from falling off by the mounting member 2e. Has been. The moving member 75 is biased toward the braking position by a spring member 77 in the form of a coil spring, for example. In the moving member 75, a spring mounting hole 75c in which the spring member 77 is mounted is formed along the pressing direction. The spring member 77 is mounted in the spring mounting hole 75c in a compressed state with the base end in contact with the housing portion 2f. The third brake shoe 75a has a contact surface 75d formed to be curved in a circular arc shape along the braking surface 38e. The switching protrusion 75b extends in a direction crossing the pressing direction.

  The switching operation unit 76 includes a switching lever 80 that is swingably mounted on the front surface of the lid member 2d, and a cam member 81 that swings integrally with the switching lever 80. The rotation range of the cam member 81 is restricted so as to rotate within a predetermined range in order to switch between the braking position and the braking release position. The cam member 81 is urged in both directions by the toggle spring 82 with the dead point of the toggle spring 82 interposed therebetween. The cam member 81 has a cam protrusion 81a that can come into contact with the switching protrusion 75b of the moving member 75, and the moving member 75 releases the brake at a position where the cam protrusion 81a shown by a solid line in FIG. The cam projection 81a is separated from the switching projection 75b at the position indicated by a thin line, and the moving member 75 is arranged at the braking position by the urging force of the spring member 77 to press the braking surface 38e.

[Reel operation and operation]
At the time of casting, the fishing line is fed out from the outer periphery of the spool 4 by tilting the bail arm 9 toward the line releasing posture and casting. At the time of winding the yarn, if the handle 1 is rotated in the yarn winding direction, the bail arm 9 returns to the yarn winding posture by a return mechanism (not shown). The rotational force of the handle 1 is transmitted to the pinion gear 12 via the master gear shaft 10 and the master gear 11. The rotational force transmitted to the pinion gear 12 is transmitted to the rotor 3 via the front portion 12a of the pinion gear 12. At this time, since the rotor 3 rotates in the yarn winding direction, the rotational force is not transmitted to the rotating member 22 due to the action of the one-way clutch 21. When the pinion gear 12 rotates, the spool shaft 8 reciprocates in the front-rear direction.

  If nothing is operated on the brake lever 50, the brake lever 50 is pressed by the action of the coil spring 49 and the first predetermined brake portion 25 and is disposed at the brake release position or the predetermined brake position.

When exchanging with the fish by reversing the rotor 3, the braking force is adjusted by pulling the first operating portion 50c of the braking lever 50 toward the rod mounting portion 2c with, for example, an index finger. At this time, as described above, the first brake shoe 51 of the brake lever 50 presses the braking surface 38e on the inner peripheral side of the second cylindrical portion 38b, and the second brake shoe 53 of the interlocking member 52 is the second cylindrical portion. The braking surface 38f on the outer peripheral side of 38b is pressed. As a result, the braking member 38 is sandwiched between the two brake shoes 51 and 53, and the force for tilting the rotating member 22 is less likely to act. For this reason, the braking force can be increased efficiently according to the operation by the braking lever 50.

  When the fishing line is pulled by the fish and the rotor 3 reverses in the line-feeding direction, the rotational force is transmitted to the rotating member 22 via the one-way clutch 21. As a result, the rotating member 22 rotates integrally with the rotor 3 in the yarn drawing direction. When the first operating portion 50c of the brake lever 50 is pulled in the direction approaching the rod mounting portion 2c, the lever member 61 swings to the brake release position side even if the brake lever 50 is at the predetermined braking position. As a result, the first predetermined braking state by the first predetermined braking unit 25 is once released. At this time, the toggle spring 62 is reversed by the swing of the lever member 61, the lever member 61 is biased toward the brake release position, and the lever member 61 is held at the brake release position (FIG. 8). When the second predetermined braking unit 26 is in the second predetermined braking state, the second predetermined braking state is maintained even if the braking lever 50 is disposed at the braking release position.

  In this state, when the brake lever 50 is further operated in a direction approaching the rod mounting portion 2c, the second cylinder portion 38b is sandwiched between the first brake shoe 51 of the brake lever 50 and the second brake shoe 53 of the interlocking member 52, so that the rotor 3 The rotation in the yarn unwinding direction is braked. This braking force can be adjusted by adjusting the force applied to the braking lever 50, and the amount of reverse rotation of the rotor 3 can be adjusted arbitrarily. As a result, a braking force corresponding to the operating force of the braking lever 50 is applied to the rotor 3. In this way, even if the user forgets to cancel the first predetermined braking state, the first predetermined braking state can be canceled by merely pulling the brake lever 50.

  When the fishing ground is moved or the reel is stowed, the second predetermined braking unit 26 is set to the second predetermined braking state by the switching operation unit 76 of the second predetermined braking unit 26, or the brake lever is operated by pressing the second operating unit 50d. 50 is arranged at a predetermined braking position, and the first predetermined braking portion 25 is set to a first predetermined braking state.

  In the second predetermined braking state, as shown in FIG. 2, the moving member 75 is disposed at the braking position and brakes the reverse rotation (rotation in the yarn unwinding direction) of the rotor 3 with a weak braking force by the biasing force of the spring member 77.

  In the first predetermined braking state, the lever member 61 is urged by the toggle spring 62 by the pressing operation of the braking lever 50 and swings toward the first predetermined position shown in FIG. Then, the positioning member 66 mounted on the lever member 61 is positioned at the first predetermined position. Then, the latching claw 70 engages with the ratchet 63a, and the rotation of the friction member 63 in the yarn unwinding direction is prohibited. Therefore, the braking force in the second predetermined braking state is determined by the elastic force of the friction ring 64 attached between the friction member 63 and the braking member 38. For this reason, it becomes easy to obtain a predetermined braking force that is strong enough that the handle 1 does not rotate even if something hits the handle 1 during the movement, and the predetermined braking force can be set so strong that no dandruff occurs during the movement of the fishing ground. . In addition, since braking is performed by the relative rotation between the friction member 63 and the braking member 38, the braking force is less likely to fluctuate and is stabilized.

  Furthermore, in order to change the hanging length of the device or to make the fish bite into the device reliably when it hits the fish, when the rotor 3 is to be released from the predetermined braking state to the brake releasing state, the braking lever 50 is set. What is necessary is just to operate in the direction which approaches the heel mounting part 2c slightly. Then, as described above, the lever member 61 is swung to the brake release position by the brake lever 50 and the first predetermined brake state is once released.
