Description

[Detailed Description of the Invention] This invention relates to a backlash prevention device for a fishing reel that brakes the spool when a set time has elapsed from the start of rotation of the spool.

Conventionally, when throwing a contraption, the clutch mechanism is turned off and the spool is rotated freely, causing the spool to rotate in a vortex.In order to prevent crushing caused by this vortex rotation, at least one side of the non-magnetic conductor rotates together with the spool. A device for preventing backlash of a fishing reel has been proposed in which a magnetic material is disposed in the spool, and the magnetic force of the magnetic material generates an eddy current in a non-magnetic conductor to magnetically brake the rotation of the spool. Since magnetic braking is applied to the rotation of the spool before the throw, the distance of long throws does not increase.For example, when throwing, the magnetic material is separated from the non-magnetic conductive material and the device flies and reaches the maximum height. Even if the structure is configured so that a magnetic body is brought close to a non-magnetic conductor by operating a lever and its magnetic force applies magnetic braking to the non-magnetic conductor to prevent crashing, in the conventional case where the brake is applied to the spool with a fingertip, Similarly, there is a drawback that requires skill, and if the clutch mechanism is engaged and the fishing line is wound without releasing the magnetic braking in the above device, the spool rotation becomes heavy. Because it is cumbersome and cumbersome to operate the magnetic brake or release the adjustment of the braking force, once the braking force is applied, the fishing line is normally operated as it is, and the fishing line is operated against the rotational braking force. The disadvantage is that the fishing line gets wound up.

The purpose of the present invention is to solve the above-mentioned drawbacks and provide a fishing reel in which the brake is automatically applied when a set time is reached from the start of rotation of the spool, and the brake is released when winding the fishing line. The object of the present invention is to propose a backlash prevention device.

The present invention will be explained below with reference to the illustrated embodiments.If a fishing reel is described as a double bearing type reel,

As shown in FIGS. 1 and 3, on one side of the spool 2, a cylindrical non-magnetic conductor 2a made of a non-magnetic material such as copper or aluminum is separately or integrally formed, and the reel side frame A yoke 22 is fitted and fixed on the inner circumferential surface of the retaining ring 21 which is fitted and fixed in the through hole 10 with a small gap between the non-magnetic conductor 2a and the circumference of the non-magnetic conductor 2a. The inside has N and S poles alternately on the outer periphery.
An arc-shaped magnetic body 6 whose poles are magnetized is fixed to the outer periphery of the arc portion 7a of the support member 7, and one end 7b of the support member having the arc portion swings on a support shaft 23 fixed to the reel side plate 1. A flat part 7c is formed at the other end of the reel side plate 1.
A plunger 8a of a solenoid 8 fixed to the solenoid 8 is connected, and the braking means for generating an eddy current in the non-magnetic conductor 2a is composed of a yoke 22, an arc-shaped magnetic body 6, a support member 7, and the solenoid 8. .

One permanent magnet 9a of a sensor 9 for detecting the start of rotation of the spool is fixed on one side of the spool 2, and the other Hall element 9b of the sensor 9 for detecting the start of rotation faces the rotation range of the permanent magnet.
is fixed to the base of the reel side plate 1.

The sensor 9 for detecting the start of rotation of the spool 2 is connected to a start/stop circuit 25 of a timer circuit 24 in FIG. 4, and the timer circuit 24 is connected to a start/stop circuit 25 connected to a counter circuit 26 and a reference time generating circuit. 27, digital program switch circuit 28, and reset detection circuit 2
9, a display unit 30 connected to the digital program circuit 28, and a relay 31 connected to the start/stop circuit 25, and the solenoid 8 and power battery 33 are connected to the relay switch 32 to create a digital program switch circuit. The relay 31 is configured to operate when the time limit set at 28 comes, and the power switch of the timer circuit 24 is provided on the reel side plate 13 in the movement area of the permanent magnet 34 fixed to the clutch operating lever 5 in FIG. It consists of a reed switch 35.

When the fishing reel buck crash prevention device is configured as described above and the tackle is thrown,
The clutch operating lever 5 is pushed in.

By this pushing operation, the clutch plate 17 and pinion 4 are moved, the clutch is disengaged, and the spool 2
As soon as the reed switch 35 is closed by the permanent magnet 34, the timer circuit 24 shown in FIG. 4 is energized and becomes operational.

Next, the time limit for braking the rotation of the spool 2 is set to, for example, 1.5 seconds from the start of rotation of the spool 2 using the digital program switch circuit 28, and the device is thrown.

When the bait is thrown, the spool 2 is rotated by the fishing line, and the permanent magnet 9a and the Hall element 9
The sensor 9 that detects the start of rotation of the spool detects the start of rotation of the spool, a detection signal is input to the start/stop circuit 25, the timer circuit 24 is started, and the digital program switch circuit 2
The time limit value set in step 8 is preset in the counter circuit 26, and when the count number reaches 0, the reset detection circuit 29 operates, and a reset signal is sent to the start/stop circuit 25, and the start/stop circuit 25 is started.
The stop circuit returns to its original state, current is applied to the relay 31, the switch 32 is switched, the solenoid 8 is energized, the plunger 8a is attracted, and the flat part 7c side of the support member 7 is pulled up as shown in FIG. The arc-shaped magnetic body 6 is connected to the non-magnetic conductor 2a.
When the non-magnetic conductor is brought close to the non-magnetic conductor, a large amount of eddy current is generated, and the magnetic force exerts a stronger influence on the rotation of the non-magnetic conductor, thereby applying braking and preventing the fishing line from becoming dandruff.

When the handle 16 is rotated after throwing the device, the actuating piece 5b of the clutch operating lever 5 is kicked up and retreated by the protrusion 36 fixed to the driving gear 15 or ratchet wheel in FIG. The engagement of the clutch plate 17 is separated and the clutch is engaged, and the permanent magnet 34 is moved back from the reed switch 35 position, so the reed switch 35 is opened and the relay 31 is de-energized, and the plunger of the solenoid 8 is turned off. 8a suction is released and spring 3
At 7, the magnetic body 6 is separated from the non-magnetic conductor 2a and returns to the state shown in FIG. 3, the generation of eddy currents is reduced and the spool 2 is rotated without magnetic braking.

The timer circuit 24 is a reset detection circuit 29.
A comparison circuit is inserted between the counter circuit 26 and the digital program switch circuit 28, and the comparison circuit sends a reset signal to the start/stop circuit, and the start/stop circuit sends a start signal to the counter circuit. Other circuit configurations may also be employed.

As mentioned above, the spool 2 is thrown in a freely rotating state where no braking is applied when casting the fishing line, and when the spool is rotated by letting out the fishing line, the sensor 9 detects the start of rotation, and the time limit value set by the timer circuit 24 is detected. The solenoid 8 brings the magnetic body 6 close to the non-magnetic conductor 2a to apply braking, and the time limit setting value is arbitrarily set by the digital program switch circuit 26, so each angler's throwing elevation angle, throwing speed, and distance are controlled. Since the time limit for activating the brake is set in consideration of the casting distance, the long casting distance of the tackle is extended, and the fishing line is prevented from collapsing.When winding up the fishing line after casting, the magnetic material automatically changes from the non-magnetic conductive material. Since the brake is released when the windings are separated from each other, the winding can be rolled up more easily.
