Description

[Detailed Description of the Invention] The present invention relates to a fishing reel, and more particularly to a fishing reel in which a spool is supported on a main body frame and the spool can be freely rotated by releasing a clutch.

Generally, this type of reel is called a double-shaft reel, and the spool is allowed to rotate freely for casting. However, during casting, the rotational speed of the spool becomes faster than the fishing line withdrawal speed.
There is a problem that a so-called buckling occurs, and the fishing line becomes unraveled and tangled, or becomes wedged into the main body frame.

Conventionally, attempts have been made to solve the problem of backlash by using a centrifugal brake or applying rotational resistance to the spool shaft by a drag mechanism, but none of these mechanisms Simply applying a brake to the spool cannot fundamentally solve the problem of buckling, and since the brake operates even when buckling does not occur, it not only affects the throwing distance but also causes damage to the spool. Optimal summing cannot be performed.

In addition, as a method for preventing the above-mentioned buck crash, when casting, the fisherman places his thumb on the outer periphery of the spool, that is, on the outer periphery of the fishing line winding part, and when a buck crash occurs, he presses his thumb against the spool outer circumference to apply the brake. This method prevents the collapse mentioned above, but it requires advanced techniques and is difficult for anglers who are inexperienced in handling it.
It was not possible to completely prevent crashes.

Therefore, the inventor of the present invention first provided a detector for electrically detecting the unraveling of the fishing line wound around the spool on the main body frame, and also provided an electrically operated brake device to detect the unraveling of the fishing line. We have proposed a reel that operates the brake device using an output signal from the reel to prevent the aforementioned backlash.

By the way, the detector in the reel devised in the earlier application uses a photointerrupter consisting of a light emitting diode and a phototransistor, and is provided on the outer periphery of a pair of bearing housings facing each other on both sides of the spool in the axial direction. The phototransistor is configured to turn on when the fishing line blocks light from the light emitting diode.
There was a problem that the brake device could not be operated accurately, resulting in malfunction.

The present invention was devised to solve the specific problem with the reel proposed earlier, and it is possible to accurately detect unraveling of the fishing line during casting and prevent unraveling without malfunction. A reflective photo sensor is attached to the main body frame to direct toward the fishing line wound on the spool, and a solenoid is operated by an output signal from the photo sensor, and the solenoid operates to resist free rotation of the spool. It is characterized by the installation of a brake device that provides

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 is in pressure contact with the master gear 4 via a spring 27, and the rotational force of the handle shaft 5 is transmitted to the master gear 4 via the friction plate 24. . still,
The pressing force can be adjusted by an adjusting body 28 screwed onto the shaft end of the handle shaft 5.

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 shaft 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. pin 83 in the direction perpendicular to
It is supported to freely reciprocate through the elongated hole 84 and biased in the backward direction by a return spring 85.

It can be engaged with the stepped portion 16b of 6a and held at the forward movement end position.

A contact body 86 is pivotally attached to the tip of the leg portion 81a to make contact with the protrusion 25 of the anti-reverse plate 26, swing the clutch lever 81, and cause the spring 85 to move the clutch lever 81 back. .

Although the contact body 86 is not necessarily required, by providing the contact body 86, the protrusion 25 is positioned within the movement path of the clutch lever 81 when the clutch lever 81 is moved forward. Even if the contact body 85 swings, the protrusion 25
This is advantageous in that the forward movement of the clutch lever 81 can be performed regardless of the position of the projection 25.

Furthermore, when providing the contact body 86, the structure is not limited to that 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,
A reflective photosensor 30 is attached to the connecting rod 13 that connects the spool 12 to the fishing line wound on the spool 3.
is provided so that the photosensor 30 electrically detects the unraveling of the fishing line, and a solenoid 40 is provided on, for example, the left frame 11 of the main body frame 1, and is operated by an output signal from the photosensor 30, and further A brake device 50 that provides resistance to the rotation of the spool 3 is provided, and the brake 50 is actuated by the operation of the solenoid 40, so that the spool 3 is braked.

The reflective photosensor 30 includes a light emitting element 32 and a light receiving section 3 in one housing 31 as shown in FIG.
The light emitting element 32 mainly uses a GaAs infrared light emitting diode or a GaP red light emitting diode, and the light receiving section 33 uses a phototransistor. said housing 3
Fishing line A whose opening side of 1 is wound around the spool 3.
It is installed facing the winding side.

Although only one photosensor 30 may be used, it is preferable to use two or more photosensors 30, and the output terminal of each photosensor 30 is connected to an AND circuit 60, a differential circuit 70, and a monostable multivibrator, as shown in FIG. 80 and is connected to the solenoid 40 via an amplifier 90.

By providing two or more photosensors 30 in this manner and connecting them to the solenoid 40 via the AND circuit, malfunctions can be further reduced and more accurate braking operation can be achieved.

Further, the photosensor 30 is connected to the spool 3.
In relation to the winding diameter of the fishing line A, the photosensor 30 is provided at a predetermined position relative to the winding diameter of the fishing line A, and the photosensor 30 is movable relative to the winding portion of the fishing line A with respect to the connecting rod 13. , the position of the photosensor 30 can be freely adjusted.

Further, the power line _l1 to the photosensor 30 and the connection line _l2 to the solenoid 40 are either placed along the connecting rod 13, or inserted into the connecting rod 13 by making it hollow as shown in FIG. Let it happen.

Note that the power source for the photosensor 30 and the solenoid 40 mainly uses a dry cell battery, and if the dry cell battery is installed inside the left side frame 11 to which the solenoid 40 is attached, or if a handle is provided,
This handle is made hollow and installed inside, or a battery box is specially provided and installed inside.

Further, the solenoid 40 is provided at a position related to the brake device 50, and the brake device 50 shown in FIG. , the disc 51 is fixed to the spool shaft 2, and a brake shoe 52 made of a leaf spring is provided.
is attached to the cover 17 fixed to the left side frame 11, and the solenoid 4 is attached to the middle of the shoe 52.
0 movable iron cores 41 are connected.

In the above configuration, when casting is performed, the clutch lever 81 is operated forward to disengage the clutch 7 and the spool 3 is made freely rotatable. When this occurs and the fishing line wound around the spool 3 comes undone, it is immediately detected by the photosensor 30, and the solenoid 40 is energized by the detection signal, thereby operating the brake device 50.

That is, in the embodiment described above, when the coil of the solenoid 40 is energized, the movable iron core 41
moves to the right in FIG. 1, and this right movement causes the brake shoe 52 connected to the movable iron core 41 to swing counterclockwise, pressing its tip against the brake disc 51 and rotating the spool 3. It provides resistance.

Therefore, the rotation of the spool 3 is braked by the resistance, and the rotation is slowed down or stopped, thereby eliminating the unraveling of the fishing line.

Moreover, when the unraveling is eliminated, the photosensor 3
The output signal from 0 disappears, and the solenoid 4
0 is demagnetized, and the spool 3 becomes free rotating again.

After casting as described above, the clutch lever 81 is moved back, the clutch 7 is engaged, and the fish is hooked. When the fish is hooked, the handle 9 is rotated. Rotate the spool 3, wind the fishing line on the spool 3,
They pull up fish. .

As is known, the backward movement of the clutch lever 81 is automatically performed by rotating the handle shaft 5 by operating 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
is in contact with the contact body 86, and in a state where the contact body 86 is pressed 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 stepped. It is separated from the portion 16b and moved back by the action of the return spring 85.

In the embodiment described above, the brake drum 51 was used as the brake device 50, but the spool 3
Alternatively, the spool shaft 2 may be used. Also, although the brake shoe 52 made of a leaf spring is used, other electromagnetic brake structures may be used.

As described above, according to the present invention, since the reflective photo sensor is used to detect the unraveling of the fishing line wound around the spool, it can be attached to the connecting rod as in the embodiment, and the mounting structure can be simplified. At the same time, the unraveling of the fishing line can be detected with high precision without malfunction. Therefore, when casting,
Only when a crash occurs, an output signal is output to activate the brake device and provide resistance to the free rotation of the spool, preventing the fishing line that has come loose from the spool from becoming entangled or getting caught in the main body frame. can be reliably prevented.

Moreover, the spool is not braked all the time, but only when the fishing line becomes unraveled due to buckling, so the casting distance is not affected and optimal summing is possible.

Furthermore, since the braking of the spool is done automatically, there is no need for anglers to worry about braking, and any number of people who are unaccustomed to using a reel can use it.
