Description

[Detailed description of the invention] The present invention is a fishing reel, in particular, a spool is supported on a main body frame, and the clutch is disengaged by reciprocating operation of a clutch lever, and the spool can be freely rotated. The present invention relates to a fishing reel in which the clutch is engaged by the backward movement of the reel.

Generally, this type of reel is called a double-shaft reel, and the spool is allowed to freely rotate for casting. However, during casting, the rotational speed of the spool becomes faster than the fishing line withdrawal speed, resulting in a so-called backlash. There is a problem that they come undone, become entangled, or get wedged into the main body frame.

Conventionally, attempts have been made to solve the problem of backlash by using a centrifugal brake or by applying rotational resistance to the spool shaft using a drag mechanism, but none of these mechanisms have the ability to Simply applying the brake cannot fundamentally solve the problem of buckling, and since the brake operates even when buckling does not occur, it affects the throwing distance and makes it difficult to set the optimum speed for the spool. Summing cannot be performed.

In addition, as a method for preventing the above-mentioned crash, when casting, the fisherman places his thumb, for example, on the outer periphery of the spool, that is, on the outer periphery of the fishing line winding part.
When a buck crash occurs, the thumb is pressed against the outer periphery of the spool to apply a brake to prevent the buck crash, but this requires advanced technique, and anglers who are inexperienced in handling the spool may not be able to completely prevent the buck crash. Ta.

Therefore, the present invention was devised in view of the above-mentioned conventional problems, and the purpose is to stop the free rotation of the spool only when a backlash occurs, thereby solving the phenomenon of fishing line entanglement and biting due to backlash. To provide a fishing reel that can be cast at a desired throwing distance.

That is, in the present invention, when a backlash occurs,
Focusing on the fact that the fishing line wound around the spool comes undone,
The unraveling of the fishing line is detected as an electrical signal, and when the fishing line unravels, the clutch is engaged to stop the free rotation of the spool before the fishing line becomes entangled or bitten. in,
A detector for detecting unraveling of the fishing line wound around the spool as an electrical signal and an electromagnet operated by the output signal from the detector are provided on the main body frame,
The electromagnet is disposed in the movement path of the clutch lever so that the clutch lever is locked in the clutch release position, and the electromagnet is energized to release the clutch lever and engage the clutch. It is characterized by being made to match.

A pinion 6 that meshes with the master gear 4 is slidably supported on the spool shaft 2, and a clutch 7 is provided between the pinion 6 and the spool shaft 2, and a clutch operating mechanism 8 operates the clutch 7. By engaging and disengaging the clutch 7, the rotational force transmitted from the handle 9 to the handle shaft 5 is transferred to the master gear 4.
This is transmitted to the spool shaft 2 via the pinion 6 and the clutch 7, causing the spool 3 to rotate, and by disengaging the clutch 7, the spool 3 can be freely rotated.

The rotating force from the handle shaft 5 is transmitted to the master gear 4 via the friction plate 24. That is, the friction plate 24, via the spring 27,
It is in pressure contact with the master gear 4, and the rotational force of the handle shaft 5 is transmitted to the master gear 4 via the friction plate 24. Note that the pressure contact force can be adjusted by an adjustment body 28 screwed onto the shaft end of the handle shaft.

Further, the clutch 7 has a flat surface in the middle part of the spool shaft 2, and the pinion 6.
The pinion 6 is configured by providing a cylindrical portion having a non-circular inner surface that engages with the flat surface, and the pinion 6
By separating the cylindrical portion from the flat surface forming portion of the spool shaft 2 by operating the operating mechanism 8, the spool shaft 2 and the spool 3 fixed to the spool 2 can be freely rotated.

The clutch operating mechanism 8 is composed of a fork-shaped clutch lever 81 and a clutch yoke 82 that holds the pinion 6, as shown in FIG. It is supported to freely reciprocate in orthogonal directions via pins 83 and elongated holes 84, and is biased in the return direction by a return spring 85.

Further, the clutch lever 81 is connected to the side plate 16.
The pin 83 fixed to the clutch lever 81 is pivotable, and a permanent magnet 90 is supported on the operating portion 81a of the clutch lever 81 via a bracket 91 so as to be swingable. And the right side frame 12
In addition, an electromagnet 40 (to be described later) is attached to the cover 18 fixed together with the side plate 16.
At the forward movement end position of the clutch lever 81, the permanent magnet 90 is attracted to the magnetic core 41 of the electromagnet 40, so that the permanent magnet 90 can be held at the forward movement end position, that is, the disengagement position of the clutch 7. Furthermore, the permanent magnet 90
The electromagnet 40 is installed on the operating portion 81a side of the clutch lever 81 as shown in FIG. 2, or on the fork-shaped clutch lever 81.
It may be provided at the tip of one of the leg portions 81b.

The electromagnet 40 generates a magnetic field when energized to repel the permanent magnet 90 against its magnetic core 41, and the electromagnet 40 of the permanent magnet 90
The polarity of the end toward the permanent magnet 90 is the same as the polarity occurring in the magnetic core 41 of the electromagnet 40 toward the permanent magnet 90.

Further, the leg portion 81 of the clutch lever 81

A contact body 86 is pivotally connected to the clutch lever 81 so that the clutch lever 81 swings and is moved back by the spring 85. This contact body 86 is a stopper 81c provided at the tip of the leg 81b.
The leg portion 81a can be engaged with the leg portion 81a.
and a spring 87 provided between the contact body 86 and the contact body 86.
As a result, the stopper 81c is brought into contact with the stopper 81c.

Although the contact body 86 is not necessarily required, by providing the contact body 86, when the clutch lever 81 is operated forward, the clutch lever 8
Even if the protrusion 25 is located within the moving path of the clutch lever 8, the contact body 85 can swing and escape from the protrusion 25.
This is advantageous in that the first forward movement operation can be performed regardless of the position of the protrusion 25.

Further, when the contact body 86 is provided, it is not limited to the structure shown in FIG. 2.

In the reel configured as described above, the present invention provides the opposite left and right side frames 11 of the main body frame 1,
12 or, as shown in FIG. 1, a detector 30 is provided on the outer periphery of the bearing housings 14 and 15 to detect the unraveling of the fishing line wound around the spool 3 as an electrical signal, and the output from the detector 30 is The electromagnet 40 is energized by a signal to release the clutch lever 81 from its forward movement end position, that is, the clutch release position, and engage the clutch 7.

As shown in FIG. 3, the detector 30 mainly uses a light emitting diode 31 and a phototransistor 32, and includes, for example, the bearing housing 14,
15 in a facing manner,
When the fishing line is unraveled, the fishing line becomes a light emitting diode 3.
When the light of 1 is blocked, the phototransistor 32
is turned on, and the electromagnet 40 connected to the phototransistor 32 is excited.

In FIG. 3, 33 is a condenser, and the electromagnet 40 is activated only when the fishing line blocks the light.
When the electromagnet 40 is excited and operated, the electromagnet 40
Since the operating time would be too short, this is provided to lengthen the operating time.

Although the power source is not shown, a dry battery is mainly used, and it may be built in the main body frame 1, but preferably, a battery box is provided separately and the light emitting diode 3 is connected to the light emitting diode 3 via an electric wire.
1 and other electrical circuits.

In the above configuration, when casting is performed, the clutch lever 81 is operated forward, and the permanent magnet 90 is moved between the magnetic cores 4 of the electromagnets 40.
At the forward end position, the clutch lever 81 is locked and the clutch 7 is disengaged, allowing the spool 3 to rotate freely.During this casting, backlash occurs and the When the fishing line wound around the spool 3 comes undone, it is immediately detected by the detector 30,
The electromagnet 40 is energized by the detection signal, and the clutch lever 81 is released from the forward movement end position, and the clutch 7 is engaged.

That is, in the embodiment described above, the electromagnet 4
When the coil 0 is energized, a magnetic field is generated to repel the permanent magnet 90 and release the clutch lever 81 from being attracted by the permanent magnet 90.

Therefore, the clutch lever 81 is moved back by the spring 85, and the clutch 7 is engaged. By engaging the clutch 7, the free rotation of the spool 3 is stopped, and by this stop, it is possible to eliminate the unraveling of the fishing line.

After casting as described above, if a fish is caught, the handle 9 is rotated to rotate the spool 3, the fishing line is wound around the spool 3, and the fish is pulled up.

Further, when the clutch lever 81 is at the forward movement end position when the handle 9 is rotated, the clutch lever 81 is automatically moved backward as the handle shaft 5 is rotated by the operation of the handle 9.

That is, as the handle shaft 5 rotates, the protrusion 25 of the reverse rotation prevention plate 26 also rotates, and the protrusion 25
However, while contacting the contact body 86 and pressing the contact body 86 against the stopper 81c of the clutch lever 81, the clutch lever 81 is swung around the pin 83, and the engaging portion 81b is moved to the stepped portion. 16b, and is caused to move back by the action of the return spring 85.

Further, the clutch lever 81 is connected to the electromagnet 4.
0 to the holder 42 as shown in Fig. 2,
The holder 42 is pivotally attached to the cover 18 via a pin 43, an operating tool 44 is provided at the free end of the holder 42, and a sprig 45 is interposed between the cover 18 and the holder 42. Accordingly, by operating the operating tool 44, the clutch lever 81 can also be released from being locked at the forward movement end position due to the attraction of the permanent magnet 90.

As described above, according to the present invention, even if a breakage occurs during casting, the breakage of the fishing line is detected and the clutch lever is immediately moved to the forward end position.
In other words, since the clutch disengagement position is released, it is possible to reliably prevent the fishing line that has come loose from the spool from becoming entangled or getting caught in the main body frame.

Moreover, since the spool is configured to rotate freely without braking during its free rotation, and only stops free rotation when the fishing line becomes unraveled due to buckling, the throwing distance is not affected. Optimal summing is also possible.

Furthermore, since the locking of the clutch lever at the forward movement end position is performed electrically, the locking means is simple and can be carried out without having to move the clutch lever backward by rotating the handle. As shown in the example, the clutch can be arbitrarily moved back and engaged by operating the operating tool.

Furthermore, since the clutch lever is automatically moved back during casting by detecting the unraveling of the fishing line, the angler does not have to worry about unraveling the fishing line, and even those who are inexperienced in using reels can use it. It becomes possible.
