DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing tidal current detector for detecting the speed of a tidal current in fishing and informing the angler of the detection result.

[0002]

2. Description of the Related Art In many cases, fishing results concentrate at a time when the direction of a tidal current changes. For this reason, the angler must always see the tide change via the fishing line hanging from the fishing rod so as not to miss this timing, and the concentration power decreases due to fatigue,
You may fall asleep at an important moment and you may miss an opportunity. In particular, the middle or bottom tidal current near the embankment is complicated depending on the shape of the embankment and land, and it is difficult to grasp the change in the tidal current.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above, and has been made in consideration of the above circumstances. Even when wind blows at night, a tidal current detection for fishing which can reliably grasp a change in the tidal current in the middle layer or the bottom near the embankment. To provide equipment.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, in order to clarify the present invention more specifically, embodiments of the present invention will be described in detail with reference to the drawings.

First, FIG. 1 shows a fishing tide detector 100 as one embodiment of the present invention. Reference numeral 1 denotes a tip rod of a fishing rod, and a tip guide 2 is inserted and fixed at the tip. The first fishing line 3 having passed through the tip guide 2 is connected to the first housing 5 via a hooked sulkan 4.
The first housing 5 is divided into left and right parts, and the joining surface 6 is joined with an adhesive. The weight 7 is connected to the second fishing line 8,
The other end of the second fishing line 8 is connected to an arm 11 fixed to a rotation shaft 10 of the rotator 9. The rotator 9 is covered by a second housing 12, and inside the second housing 12,
A protrusion 14 is provided to fit into the recess 13 on the outer periphery of the rotator 9, and the rotator 9 rotates around the rotation shaft 10.

A resistor 15 having a shape shown in FIG. 2 is fixed to the back surface of the rotator 9, and a contact 17 at the tip of a lead wire 16 penetrating the wall of the second housing 12 is connected to the resistor 15. And another contact 19 is connected to the resistor 1.
5 is in contact with the outer periphery 20. Therefore, when the rotator 9 rotates, the resistance value between the contact 17 and the contact 19 changes.

When the angler sinks the weight 7 and the second fishing line 8 into the sea, the weight 7 is swept by the tidal current and rotates the rotator 9 via the arm 11.

Reference numeral 21 denotes an LED for indicating to the angler the angle at which the weight 7 was swept by the tide. The LED 21 changes the blinking interval according to the angle at which the weight 7 is caused to flow by the tide.
In the embodiment, when the angle at which the weight 7 flows is in a range from 0 degree or more to less than 2 degrees, blinking is performed at intervals of 2 seconds. Is blinking at 0.5 second intervals, and is turned on at 15 degrees or more. The angler increases the concentration by visually checking the blinking of the LED 21.

Reference numeral 22 denotes a control board, which inputs an electric signal from the resistor 15 to the control board 22 to perform A / D conversion, and
An electric component including an A / D-equipped one-chip microcomputer 23, a resistor 24, and the like for blinking is soldered. A lithium battery 25 for supplying power to the control board 22 is provided outside the first housing 5, and a battery case 2 which opens counterclockwise around the hinge 26 of the first housing 5 as a rotation center.
7.

The bottom surface of the first casing 5 is inclined, and a slit 28 1 mm wider than the plate thickness of the arm 11 is provided so that rainwater does not enter the first casing 5. I have. Since the first housing 5 is connected to the first fishing line 3, it rotates without resistance. In the embodiment, the first fishing line 3 uses No. 2, the second fishing line 8 uses No. 0.6, and the weight 7 uses No. 3 fishing tackle. In addition, in the case of ebb tide with weak tide, etc., the annular foam material 29 shown in FIG.
Can be attached to

Although the embodiment of the present invention has been described above in detail, this is a literal example, and the present invention
By the specific description in such an embodiment,
It is not to be construed as limiting.

For example, in the above-mentioned embodiment, the presenting means is constituted by an LED which can be visually recognized at night, but may be a buzzer. If the buzzer sounds stepwise according to the angle at which the weight 7 is swept by the tidal current. The angler can take a nap when the tide is stationary and enjoy fishing without losing any opportunity.

[0015]

As is apparent from the above description, in the fishing tidal current detector having the structure according to the present invention, the angle at which the weight hanging from the fishing line is caused to flow by the tidal current is determined by the resistance provided on the rotor. The angle is detected by the resistance value between the body and the contact provided on the second housing that covers the rotor, and is presented to the angler based on the detection result. Also, it is possible to accurately grasp the change in the tidal current at the middle or bottom near the embankment.
