Description

[Detailed explanation of the invention] This invention is a fishing reel, more specifically, a spool supported on the main body frame, which can be moved by detaching the clutch.
This invention relates to a fishing reel that can rotate freely.

Generally, this type of reel is called a double-shaft reel,
Casting is carried out by allowing the spool to rotate freely, but during casting the rotational speed of the spool becomes faster than the speed at which the fishing line is pulled out, resulting in a so-called bump crash, which causes the fishing line to come undone.
There are problems with them getting tangled or getting wedged into the body frame.

Conventionally, attempts have been made to solve the problem of the spool by using a centrifugal brake or applying rotational resistance to the spool shaft using cast control. 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. Although the above-mentioned buck crash is prevented, it requires a sophisticated technique, and anglers who are inexperienced in handling the fish cannot completely prevent the buck crash.

Therefore, the inventor of the present invention first installed a detector on the main body frame to electrically detect the unraveling of the fishing line wound around the spool, 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.

Incidentally, 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 in opposing manner 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. The main body frame is provided with two or more contact pieces extending to the body of the spool and located radially outward of the body,
While imparting conductivity to the fishing line wound around the body of the spool, the frame detects unraveling of the fishing line wound around the spool due to a short circuit between the contact pieces caused by the fishing line, and prevents the spool from rotating freely. It is characterized by operating a brake device that provides resistance to the motion.

Embodiments of the reel of the present invention will be described below based on the drawings.

The reel shown in FIG. 1 has a spool 3 rotatably supported within a main body frame 1 via a spool shaft 2, a handle shaft 5 having a master gear 4 supported on the main body frame 1, and 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.

Further, the bearing housings 14 and 15 have a portion on the outer periphery with a diameter slightly larger than the outer diameter of the flange of the spool 3, and a boss portion in the center,
Ball bearings 20 and 21 are incorporated into each boss portion to support the spool shaft 2.

The bearing housing 1 incorporated into the left side frame 11
4 is in the shape of a deep dish, and has an inner cavity 10 formed at an intermediate portion between the flange and the boss.
In FIG. 1, a centrifugal brake 22 is installed in the inner cavity 10, but this brake 22 is not particularly necessary.

Also, a side plate 16 attached to the outside of the right side frame 12
In this case, a support rod 23 is fixed, and the handle shaft 5 is rotatably inserted into and supported by the support rod 23, and the master gear 4 is fitted onto the handle shaft 5.
Then, a friction plate 24 and a reversal prevention plate 26 having a plurality of protrusions 25 are inserted.

Further, the friction plate 24 and the anti-reverse plate 26 are inserted into the handle shaft 5 in a non-rotatable manner so as to rotate together with the handle shaft 5, and the master gear 4 is arranged so that the master gear 4 has no play in the handle shaft 5. 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 pressure contact force can be adjusted by an adjustment body 28 screwed onto the 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.

Further, the clutch lever 81 is connected to the side plate 16.
The clutch lever 81 has a fork shape and is swingable about the pin 83 fixed to the clutch lever 81.
An engaging portion 81b is provided at the tip of one of the leg portions 81a, so that it can be held at the forward end position by engaging with the stepped portion 16b of the notch 16a provided in the side plate 16 at the forward end position. There is.

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. . This contact body 86 is adapted to be able to engage with a stopper 81c provided at the tip of the leg portion 81a, and a spring 87 provided between the leg portion 81a and the contact body 86 causes the stopper 81c to engage with the stopper 81c.
It touches c.

Although the contact body 86 is not necessarily required, by providing the contact body 86, the protrusion 25 can be positioned within the movement path of the clutch lever 81 when the clutch lever 81 is operated forward. Also, the contact body 85 swings and 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.

The present invention has a reel configured as described above,
Opposing left and right side frames 11 and 12 of the main body frame 1
Or the bearing housings 14, 15, in the drawings, the right side frame 12, from a position outward from the outer peripheral surface of the flange 3b of the spool 3, the body 3a of the spool 3.
Two or more conductive contact pieces 30 are provided in parallel with the spool shaft 2 and are arranged radially outward of the body 3a, and the fishing line a is wound around the body 3a of the spool 3. is made conductive so that the contact piece 30 can electrically detect the unraveling of the fishing line a, while providing resistance to the free rotation of the spool 3, for example, to the left side frame 11 of the main body frame 1. A brake device 50 is provided to detect the unraveling of the fishing line a wound around the spool 3 due to a short circuit between the contact pieces 30, 30 caused by the fishing line a, and by this detection signal, the brake device 50
This is done by operating the spool 3 as if braking the spool 3.

The contact piece 30 mainly uses a rod-shaped electrode with a small diameter, and one end thereof is attached to the main body frame 1.
The attachment end is connected to, for example, a solenoid 40 via a detection circuit, a timer, and an output circuit as shown in FIG.
A current is applied to the solenoid 40 for a certain period of time in response to a detection signal caused by contact with the brake device 5.
It is like operating 0. Note that this contact piece 30 is provided on the side of the main body frame 1 that is attached to the fishing rod, as shown in FIG. 4, and near the connecting rod 13 that connects the left and right side frames 11 and 12.
The mounting position is not particularly limited. However, by providing it near the connection rod 13 that is attached to the fishing rod, there is an advantage that the risk of damage to the contact piece 30 when the reel is used can be reduced. Further, the contact pieces 30 are provided at predetermined intervals in the rotational direction of the spool 3, and when three or more contact pieces are provided, when the fishing line a comes into contact with two or more contact pieces 30, 30, This is done by operating the solenoid 40. By providing three or more of these, there is an advantage that the unraveling of the fishing line can be detected more accurately and quickly. or,
The contact piece 30 may be formed of a conductive material other than the electrode, and may be attached at only one end or at both ends.

Further, the means for imparting conductivity to the fishing line a may be, for example, mixing carbon into the synthetic resin material forming the fishing line, coating the surface of the fishing line with carbon, or coating the surface of the fishing line with ultra-thin magnetic tape or the like. Coating with copper imparts conductivity.

Further, the solenoid 40 for operating the brake device 50 is provided at a position related to the brake device 50, and the brake device 50 shown in FIG. 51 to fix the disk 51 to the spool shaft 2,
A brake shoe 52 made of a leaf spring is attached to the cover 17 fixed to the left side frame 11, and a movable iron core 4 of the solenoid 40 is installed in the middle of the brake shoe 52.
It is a concatenation of 1.

The power source for the solenoid 40 mainly uses a dry cell battery, and the dry cell battery may be installed inside the left side frame 11 to which the solenoid 40 is attached.
Alternatively, if a handle is provided, the handle may be made hollow and housed inside, or a battery box may be specially provided and housed inside.

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 happens and the fishing line wound around the spool 3 unravels, this unraveled portion comes into contact with, for example, the two contact pieces 30, 30, and a short circuit between the contact pieces 30, 30 due to this contact causes the above-mentioned The loosening is immediately detected, and the solenoid 40 is energized by the detection signal to operate the brake device 50.

That is, in the embodiment described above, when the coil of the solenoid 40 is energized, the movable iron core 4
1 operates in the direction of arrow X in FIG. 1, and this left movement causes the brake shoe 52 connected to the movable iron core 41 to swing counterclockwise in FIG. 1, and its tip is pressed against the brake disc 51. This provides resistance to the rotation of the spool 3.

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.

Further, when the unraveling is eliminated, the output signal from the contact piece 30 disappears, the solenoid 40 is demagnetized, and the spool 3 returns to a free rotation state.

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. is not particularly limited. Further, although the solenoid 40 is used as a means for operating the brake device 50, it is also possible to use an ultra-small motor and operate the brake device by driving the motor. It is not limited.

As described above, the present invention uses two or more contact pieces and imparts conductivity to the fishing line wound around the spool to detect the unraveling of the fishing line. Therefore, the unraveling of the fishing line can be detected with high accuracy without malfunction. It can be detected. Therefore, only when a crash occurs during casting, an output signal is output to operate the brake device and provide resistance to the free rotation of the spool. This can reliably prevent it from digging into the main body frame.

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.
