Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a braking device for a spinning reel for fishing.

[Conventional technology]

Conventionally, in spinning reels, the one disclosed in Japanese Utility Model Laid-Open No. 60-5369 and Japanese Utility Model Laid-Open No. 60-67075 has been known as a method for performing rotor braking and reverse rotation preventing hook removal by a brake lever.

Further, in Japanese Utility Model Publication No. 61-3325, by pulling up the operating portion of the lever, the locking claw is disengaged from the ratchet wheel without the operation of the picker, and the ratchet wheel and the locking claw are again separated. A technique has been disclosed in which a grip is operated to perform engagement.

In addition, in Japanese Utility Model Laid-Open No. 58-135269, the investigative tool is raised,
A technique is disclosed in which a braking member of a braking body slides in parallel with a spool shaft via an oscillating body when a pushing operation is performed. As a result, the braking member is pressed against the braking surface provided on the rotating frame, and the rotating frame can be braked.

[Problems to be solved by the invention]

However, in the spinning reel disclosed in Japanese Utility Model Laid-Open No. 60-5369, when the brake lever is released, the reverse rotation preventing pawl immediately engages with the ratchet to prevent the rotor from rotating backward. Therefore, when the brake lever is released, the rotor cannot be maintained in a free state, and it is extremely inconvenient to operate the rotor to release the fishing line, which is required for delicate fishing, and it is extremely inconvenient. There is a problem that it may cause fishing line breakage.

Also, in the spinning reel disclosed in Japanese Utility Model Laid-Open No. 60-67075, the reverse rotation preventing pawl is provided when the brake lever is released.
A separate stopper is provided to prevent the brake lever from turning on (so as not to engage the ratchet).
In order to prevent the reverse rotation preventing pawl from turning on, it is necessary to operate this stopper before releasing the brake lever. Therefore, there is a problem that the operation is complicated and it is not possible to flexibly cope with the pulling of the fish.

Moreover, in the spinning reel disclosed in Japanese Utility Model Publication No. 61-3325, the pin of the operating rod is pressed and rotated at the other end. Therefore, the power factor is reduced due to friction and the operation becomes heavy. Further, the braking force is not applied to the rotor at the same time when the ratchet wheel and the locking claw are disengaged. Further, a large part such as a squealing claw is required in the braking member storage portion, and there is a problem that a large reel body must be used to store the braking member and the brake shoe braking shaft.

Further, in the spinning reel disclosed in Japanese Utility Model Laid-Open No. 58-135269, the braking member is pressed against the braking surface of the rotating frame by the swinging member linked with the lifting and lowering operation of the operating tool to apply the braking force to the rotating frame. Multiply Therefore, the parts constituting the transmission mechanism, that is, the outer wire, the inner wire, the oscillating body, the braking body, the spring, and the like are required, and the transmission efficiency of the pressing force is poor, and the braking force cannot be sufficiently applied.
Furthermore, the structure of the main body becomes complicated, skill is required for assembly, and the reverse rotation stop mechanism is not released at the moment when the braking force is applied, so if the braking force is reduced carelessly, the reverse rotation stop will work and the fishing line will be cut. There is.

The present invention is intended to solve the above-mentioned problems of the prior art. It is possible to easily control the rotation of a desired rotor with a simple structure without enlarging the reel body and to improve the transmission efficiency of the braking force. An object of the present invention is to provide a spinning reel braking device that can be improved.

[Action]

In the braking device for the spinning reel according to the present invention,
When the anti-cam shaft is in the first state and the operation section is pulled up, the operation section moves to the side opposite to the reel body side. The anti-cam shaft engaging portion is pressed by the actuating portion to be in the second state in which the anti-cam shaft is moved to the side opposite to the reel body. When the anti-cam shaft is in the second state, the anti-cam switches the reverse rotation stop claw from the engaged state to the released state. As a result, the engagement between the ratchet and the reverse rotation stop claw is released.

On the other hand, when the operating portion is pulled up, the actuating portion presses the braking shaft engaging portion, resists the braking shaft biasing member, and moves the braking shaft to the side opposite to the reel body. To move. As a result, a braking force is applied to the inner wall portion of the rotor via the braking body.

The braking shaft urging member urges the braking shaft in the reel body side direction so that the braking shaft engaging portion engages with the operating portion. Therefore, when the pulling-up operation of the operation portion is released, the braking shaft moves in the reel body side direction by the braking shaft biasing member. The operating portion of the brake lever engages with the braking shaft engaging portion and moves in the reel body side direction together with the braking shaft. When the operating portion moves toward the reel unit side, the brake lever rotates so that the operating portion moves in the direction opposite to the pulling direction, and returns to the original state.

On the other hand, the anti-cam shaft is held in the second state by the anti-lever. In this way, only the braking shaft is returned to return. That is, simply by operating the brake lever, the engagement between the ratchet and the reverse rotation stop pawl is released, and the braking force can be controlled by adjusting the operation amount of the brake lever.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, a rotor 4 and a ratchet 5 for preventing reverse rotation are fixed to a tube shaft 3 rotatably supported by a shaft support 2 at the front end of the reel unit 1. A pinion 6 provided at the rear end of the tube shaft 3 is meshed with a main gear 8 of a handle shaft 7 rotatably supported on the reel unit 1.
The handle shaft 7, the rotor 4 and the ratchet 5 work together.

As shown in FIGS. 4 and 5, on the flange 9 extending from the reel body 1 into the rotor 4, a reverse stop claw 10 that can be engaged with and disengaged from the ratchet 5 is attached by a shaft 11 such as a step screw. It is rotatably supported. That is, the reverse rotation stop claw 10 is configured to be switchable between an engaged state in which the ratchet 5 is engaged and a released state in which the ratchet 5 is not engaged. The reverse rotation stop claw 10 has one end hooked on the front flange 9 and the other end hooked on the reverse rotation stop claw 10 and is urged in a direction in which the ratchet 5 is engaged by a spring 12 interposed therebetween. Is pivotally supported.

As shown in FIG. 6, the braking body 13 is rotatably supported by the shaft 14 so as to brake the rotor 4 by pressing the brake shoe 13a at one end against the inner peripheral wall 4a of the rotor 4. There is. In addition, one end of the front flange 9
The spring 15 is urged in the direction in which the brake shoe 13a is separated from the inner peripheral wall 4a by a spring 15 stretched by hooking the other end of the brake body 13 to the other end of the braking body 13 and axially supporting the brake shoe 13a. Has been done.

As shown in FIG. 1, the front wall 1a of the reel body 1 and the boss portion
An anti-cam shaft 16 and a braking shaft 17 are provided so as to penetrate through 1b respectively. The anti-cam shaft 16 is provided so as to be slidable in the front-rear direction and parallel to the tube shaft 3. Further, the reverse rotation stop claw 10 is provided in front of the tip of the anti-cam shaft 16 (see FIGS. 4 and 5). The braking shaft 17 is provided so as to be slidable in the front-rear direction and parallel to the tube shaft 3. The braking body 13 is provided in front of the tip of the braking shaft 17 (see FIG. 6).

As shown in FIG. 1, an actuating plate 16a serving as an engaging portion is provided at a substantially central portion of the anti-cam shaft 16. An anti-cam 16b is formed at the tip of the anti-cam shaft 16. The anti-cam shaft 16 slides in the rotor side direction (opposite to the reel body side), and
16b abuts on the operating piece 10a of the reverse rotation stop claw 10. As a result, the reverse rotation stop claw 10 rotates in the OFF direction (direction released from the ratchet) against the spring force (see the state shown by the dotted line in FIG. 4).

Further, as shown in FIG. 3, an operating plate 17a, which is a braking shaft engaging portion, is provided at a substantially central portion of the braking shaft 17. By sliding the braking shaft 17 forward (on the side opposite to the reel body), as shown in FIG.
Press the other end of. As a result, the brake shoe 13a is pressed against the rotor inner peripheral wall 4a, and the braking body 13 rotates in the braking direction against the spring force. Also,
As shown in FIG. 3, the braking shaft 17 is provided with a return spring 18 which is a braking shaft biasing member in order to return the braking shaft 17 backward.

As shown in FIG. 1, the reel body 1 includes reel legs.
Brake lever 20 having an operating portion 20a below the front of 19
Is rotatably supported by a shaft screw 21 in a vertically rotatable manner. An operating portion 20b is formed at the lower end of the brake lever 20 so as to be bent downward. The operating portion 20b is the operating plate 1 of the anti-cam shaft 16 described above.
As shown in FIG. 3 while engaging with the rear part of 6a,
The braking shaft 17 is engaged with the rear portion of the operating plate 17a. By pulling up the brake lever 20 and rotating the operating portion 20a as shown by the two-dot broken line in FIG.
16 and the braking shaft 17 move forward respectively against the elastic force of the spring 18.

An anti-lever 22 is pivotally supported on the reel body 1 by a shaft screw 23 so as to be switchable (rotatable). One end of a connecting cam 24 is fixed to the anti-lever 22 with a shaft screw 23. A long hole 24a is formed at the other end of the connecting cam 24. A connecting pin 25 is provided so as to project from the rear portion of the anti-cam shaft 16. By engaging the connecting pin 25 with the long hole 24a, the connecting cam 24 and the anti-cam shaft 16 are interlocked and connected.

A dead point spring 26 is interposed in the connecting cam 24 by hooking one end of the connecting cam 24 and the other end in a proper position of the reel body 1. Therefore, the anti-lever 22 integrally connected to the connecting cam 24 is urged to be distributed to both ON and OFF positions indicated by ab in FIG. That is, the anti-lever 22 is urged by the spring force from the dead point of the dead point spring 26 toward either the ON (position a) or the OFF (position b).

As shown in FIG. 1, the spool shaft 27 has a spool 28 fixed to the tip thereof and inserted into the tube shaft 3. By the rotation of the handle shaft 7, the spool 28 reciprocates in the front-rear direction via an oscillating mechanism (not shown). As shown in FIG. 2, the handle 29 is the handle shaft 7.
It is fixed to.

Next, the operation of the proposed braking device will be described. Normally, the braking shaft 17 is retracted by the spring force of the return spring 18, and is held at the position shown by the solid line in FIG. In this state, the spring
With respect to the braking body 13, the brake shoe 13a is held by the position 15 at a position separated from the rotor inner peripheral wall 4a.

On the other hand, since the anti-cam shaft 16 is in the retracted position when the anti-lever 22 is in the position (position a) shown by the solid line in FIG. 1, the reverse rotation stop pawl 10 is ON when the ratchet 5 is engaged.
In this state (position a), the reverse rotation of the rotor 4 is blocked. In the present embodiment, the state of being in the retracted position (moving to the reel unit side) corresponds to the first state.

That is, in this state, the return spring interposed in the braking shaft 17
The brake lever 20 is held by 18 by the position shown by the solid line in FIG. On the other hand, as shown in FIG. 1, since the spring force of the return spring 18 is not biased to the anti-cam shaft 16, the anti-lever 22 is turned on and off regardless of the braking shaft 17 and the brake lever 20. Can be switched.

When the anti-lever 22 is turned on (position a), the operation unit 20
A is pulled up, and the brake lever 20 is rotated from the position indicated by the solid line to the position indicated by the two-dot broken line, as shown in FIG.
As a result, the operating portion 20b presses the operating plates 16a, 17a, so that the anti-cam shaft 16 and the braking shaft 17 are pushed forward against the spring force and come to the positions shown by the two-dot broken line in the figure ( (See FIGS. 1 and 3). At this time, as shown in FIG. 1, the anti-lever 22 is switched from ON (position a) to OFF (position b) beyond the dead point of the dead point spring 26.

As the anti-cam shaft 16 moves forward, the anti-cam 16b pushes down one end 10a of the reverse rotation stop claw 10 in FIG. This causes the reverse rotation stop claw 10 to rotate against the spring force,
The reverse rotation stop claw 10 is released from the ratchet 5 and the rotor 4 is released.
Is positive. It becomes a reversible free state. In the present embodiment, the state in which the anti-cam shaft 16 is in the advanced position (the state in which it is moved to the side opposite to the free body side) corresponds to the second state.

That is, in this embodiment, when the operation portion 20a is pulled up, when the anti-cam shaft 16 is in the first state, the operating portion 20b presses the operating plate 16a which is the anti-cam shaft engaging portion. Then, the anti-cam shaft 16 is moved from the first state to the second state.

At the same time, the braking body 13 is pressed and rotated by the tip of the braking shaft 17 against the spring force. As a result, the brake shoe 13a is pressed against the inner peripheral wall 4a of the rotor 4, and the rotor 4 is braked. The braking force is proportional to the pulling force of the brake lever 20. In this embodiment, the braking body 13 and the brake shoes 13a form a braking member.

That is, in this embodiment, the operating plate 17a is the operating portion 2
When 0b moves to the side opposite to the reel body side, this operating unit 20
It is pressed by b and moves the braking shaft 17 to the side opposite to the reel body side.

Then, when the brake lever 20 is released, the braking shaft 17 is retracted by the return spring 18. Therefore, the brake lever
20 also reverses and returns to the position shown by the solid line in the figure,
The braking body 13 reverses and returns by the spring 15, and the rotor 4 is no longer braked.

On the other hand, the anti-cam shaft 16 is held at the advanced position by the dead point spring 26 interposed in the connecting cam 24 without returning to the backward direction. Therefore, the reverse rotation stop claw 10 is ON
The rotor 4 is maintained in the OFF state without being switched to, and the rotor 4 is maintained in the free state. Thus, in this embodiment, the anti-lever 22 switches and holds the anti-cam shaft 16 in the first state or the second state by the dead point spring 26 interposed in the connecting cam 24.

In order to switch the reverse rotation stop claw 10 to ON, the anti-lever 22 is switched from position b to position a in FIG. As a result, the reverse rotation stop claw 10 meshes with the ratchet 5 by the spring force and is switched to ON.

In the braking device for the spinning reel according to the present invention,
Braking shaft 17 and anti-cam shaft 16 have working plates 17a, 16 respectively
a is fixed, and the two axes are provided in parallel inside the reel body 1. Further, the operating portion 20b of the brake lever 20 is engaged with the respective operating plates 17a and 16a, so that the brake lever 20
This operation part 20b is linked to the operation part 20a of the
Moves. With this movement, the two axes move in the same direction. That is, the two axes can move in parallel with the spool shaft 27. As a result, these mechanisms can be stored without increasing the size and thickness of the reel unit 1.
That is, it is possible to reduce the size and weight.

Further, since the operation of the brake lever 20 is transmitted by the linear movement of the braking shaft 17 and the anti-cam shaft 16, the operation can be performed efficiently and lightly.

Further, the anti-reverse rotation device is released by the anti-cam shaft 16, and the braking shaft 17 is moved only by operating the brake lever 20, whereby the braking operation of the rotor 4 can be controlled. Therefore, it is possible to flexibly respond to the pulling of the fish.

Furthermore, even if the lifting force of the brake lever 20 is released,
Since the reverse rotation stop mechanism is still released, even if the rotor reverses carelessly, the fishing line is paid out from the spool 28 and the cutting of the fishing line can be prevented.

[Effect of device]

In the braking device for the spinning reel according to the present invention,
When the anti-cam shaft is in the first state and the operation section is pulled up, the operation section moves to the side opposite to the reel body side. The anti-cam shaft engaging portion is pressed by the actuating portion to be in the second state in which the anti-cam shaft is moved to the side opposite to the reel body. When the anti-cam shaft is in the second state, the anti-cam switches the reverse rotation stop claw from the engaged state to the released state. As a result, the engagement between the ratchet and the reverse rotation stop claw is released.

On the other hand, when the operating portion is pulled up, the actuating portion presses the braking shaft engaging portion, resists the braking shaft biasing member, and moves the braking shaft to the side opposite to the reel body. To move. As a result, a braking force is applied to the inner wall portion of the rotor via the braking body.

The braking shaft urging member urges the braking shaft in the reel body side direction so that the braking shaft engaging portion engages with the operating portion. Therefore, when the pulling-up operation of the operation portion is released, the braking shaft moves in the reel body side direction by the braking shaft biasing member. The operating portion of the brake lever engages with the braking shaft engaging portion and moves in the reel body side direction together with the braking shaft. When the operating portion moves toward the reel unit side, the brake lever rotates so that the operating portion moves in the direction opposite to the pulling direction, and returns to the original state.

On the other hand, the anti-cam shaft is held in the second state by the anti-lever. In this way, only the braking shaft is returned to return. That is, simply by operating the brake lever, the engagement between the ratchet and the reverse rotation stop pawl is released, and the braking force can be controlled by adjusting the operation amount of the brake lever.

By thus providing the anti-cam shaft and the braking shaft in parallel, these mechanisms can be housed without increasing the size and thickness of the reel unit.
That is, it is possible to provide a braking device for a spinning reel that can easily control the rotation of a desired rotor with a simple structure without enlarging the reel body.

Further, since the braking shaft and the anti-cam shaft transmit the operation of the brake lever by linear motion, efficient and light operation is possible. That is, it is possible to provide a braking device for a spinning reel that can improve the transmission efficiency of the braking force with a simple structure without increasing the size of the reel body.

When the brake lever is operated, the anti-cam shaft holds the reverse rotation prevention mechanism in the released state, and the braking shaft moves, so that the braking operation of the rotor can be controlled. Therefore, it is possible to provide a braking device for a spinning reel that can flexibly cope with the pulling of fish.

Further, even if the pulling force of the brake lever is released, the reverse rotation stop mechanism remains released, so that a spinning reel braking device that can prevent the cutting of the fishing line even if the rotor reverses carelessly is provided. can do.
