Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric float having a structure in which the lighting state is changed according to the degree of submersion of a float body.

[0002]

2. Description of the Related Art In an electric float used for night fishing, a technique has been proposed in which the lighting state is changed as the float body is submerged in water in order to inform a fisherman of a clear fish catch. As an example of this, there is a configuration in which two lamps having different lighting colors are provided and the electrodes of one lamp are exposed to the outside of the float body. In the case of this configuration, when the float body is submerged in water, the electrodes are electrically conducted using water as a medium, and as a result, one of the lamps is turned on to notify "the fish is present".

[0003]

In the above-mentioned prior art, since the lamp is lit by using water as a medium, if the electrode is covered with water by wind or waves, the lamp is erroneously lit. Therefore, a configuration for detecting a pressure change caused by submersion of the float body and switching the lighting color is disclosed in "Jpn. Pat. Appln. KOKAI Publication No. 2-36395" and "Jpn. Pat. However, with this configuration, a means for detecting a pressure change is required, which leads to a complicated configuration and an increase in cost.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an electric float capable of preventing erroneous lighting due to wind and waves, and having a simple structure and low cost.

[0005]

An electric float according to claim 1, wherein a first light emitting diode is provided in the float body and has a normally closed power supply path, and the first light emitting diode is provided in the float body. A second light emitting diode connected in parallel to the floating body, and a switch device provided in the float body and interposed in a power feeding path for the second light emitting diode, the switch device being exposed outside the float body. A contact piece and a moving float that moves with respect to the float body when the float body is submerged, and a moving float that is provided on the moving float and comes into contact with the fixed contact piece as the moving float moves to connect the power feeding path. It is characterized in that it has a movable segment that closes.

In the electric float according to the second aspect, the emission color of the first light emitting diode and the emission color of the second light emitting diode are different, and the emission efficiency of the second light emitting diode is higher than the emission efficiency of the first light emitting diode. However, it has a feature.

[0007]

According to the means described in claim 1, the light emitting state changes as follows according to the degree of submersion of the float body. (1) When the float body is not submerged in water: The movable piece of the moving float separates from the fixed contact piece, and the switch device is turned off. Therefore, the power supply path for the second light emitting diode is opened by the switch device, and only the first light emitting diode having the normally closed power supply path emits light.

(2) When the float body is submerged in water As the movable float moves relative to the float body, the movable contact piece of the movable float contacts the fixed contact piece and the switch device is turned on. Therefore, the power supply path for the second light emitting diode is closed, and the second light emitting diode emits light.

(3) When the main body of the float is submerged by wind or waves, the switch device is turned on by using water as a medium, and a current flows through the second light emitting diode. However, since the second light emitting diode itself has a high internal resistance and water is interposed in the power supply path of the second light emitting diode, the combined resistance increases, and as a result, erroneous light emission of the second light emitting diode is prevented. Moreover, since the second light emitting diode and the first light emitting diode are connected in parallel, power is supplied to the first light emitting diode through a unique path in which water is not interposed, and as a result,
The first light emitting diode is kept in a light emitting state.

According to the second aspect of the invention, since the emission color of the first light emitting diode and the emission color of the second light emitting diode are different, the emission color changes according to the degree of submersion of the float body. Moreover, since the light emitting efficiency of the second light emitting diode is higher than that of the first light emitting diode, the second light emitting diode emits light more clearly than the first light emitting diode.

FIG. 2 shows a light emitting circuit 16 composed of a power supply battery 3, a first LED 11 and a second LED 13. As is apparent from the figure, the second LED 13 is connected in parallel to the first LED 11. Cage, fixed contact piece 1
When 5a and 15b are electrically connected, power is supplied from the power supply battery 3 to both the first LED 11 and the second LED 13. Reference numeral 17 in FIG. 1 denotes a float body composed of a main body case 1, a battery case 2, a lower case 4, an upper case 10 and a cover 12. The floating body 17 is made up of the lower case 4. Along with the insertion of the line insertion hole 4b into the fishing line, the fishing line is attached to a fishing tackle.

A movable float 18 is provided on the outer periphery of the cylindrical portion 10a.
Is mounted so that it can move up and down. This moving float 18
The movable cover body 18a is formed in a hollow shape by adhering the bottom cover 18b to the bottom surface of the movable float body 18a, and has a buoyancy enough to float in water. A plurality of convex portions 18c are integrally formed on the bottom cover 18b.
A gap is formed between 8b and the upper case 10. Therefore, when the fish hooks and the float body 17 is submerged in water, water enters the gap between the bottom cover 18b and the upper case 10,
The movable float 18 slides upward with respect to the cylindrical portion 10a. The main body case 1, the battery case 2, the lower case 4, the pressing member 6, the upper case 10, the cover 12, the movable float main body 18a, and the bottom cover 18b are manufactured by injection molding a transparent synthetic resin.

The movable contact piece 1 is provided on the upper surface of the movable float body 18a.
9 is glued. The movable contact piece 19 is made of stainless steel foil, and the movable float 18 has a cylindrical portion 10.

Conduction is made between the terminals 15b and 15b. This allows the power supply battery 3
Power is supplied from the second LED 13 to the second LE.
D13 lights up in red. Reference numeral 20 in FIG. 1 indicates fixed contact pieces 15a and 15b, a movable float 18, a movable contact piece 19.
2 shows a switch device composed of

According to the above embodiment, when the fish is not hooked, the float body 17 is floating in the water, and the moving float 18 is located at the base end of the cylindrical portion 10a. Therefore, the movable contact piece 19 of the movable float 18 is separated from the fixed contact pieces 15a and 15b, and only the first LED 11 lights up in yellow. In this state, the float body 17 is affected by wind and waves.
When the fixed contact pieces 15a and 15b are exposed to water,
Conduction is established between the fixed contact pieces 15a and 15b using water as a medium, and a current flows through the light emitting circuit 16.

In this case, the first LED 11 and the second LE
Since D13 is connected in parallel, current I1 flowing through the first LED 11 and current I2 flowing through the second LED 13
Is as follows. I1 = V / R1 I2 = V / Rx where V is the voltage of the power supply battery 3,
R1 is the internal resistance of the first LED 11, Rx is the second LED1
3 is a combined resistance and is represented by the following equation. Rx = R2 (Internal resistance of the second LED 13) + Rw (Water resistance)

As is clear from the above equation, the internal resistance R2 of the second LED 13 is larger than that of the conventional lamp, and the energization resistance Rw of water is added, so that Rx becomes extremely large. Therefore, the current I2 flowing through the second LED 13 becomes smaller than the drive current, and as a result, the erroneous lighting of the second LED 13 is prevented. Moreover, since power is supplied to the first LED 11 through a unique path that does not involve water,
The LED 11 will be kept in a light emitting state.

When the fish hooks and the float body 17 sinks, the movable float 18 moves above the cylindrical portion 10a and the movable contact piece 19 contacts the fixed contact pieces 15a and 15b. Then, the fixed contact pieces 15a and 15b are electrically connected to each other, and power is supplied from the power supply battery 3 to the second LED 13. Therefore, since the emission color can be switched with a simple configuration in which the movable float 18 is added, the configuration is simplified as compared with the conventional case in which the pressure change due to the submersion of the float body is detected. Moreover, since the emission color of the first LED 11 is yellow and the emission color of the second LED 13 is red, there is also an advantage that it becomes easy to visually confirm submersion of the float body 17.

By the way, the LED has a property that the luminous efficiency (internal resistance) varies depending on the lighting color thereof, and the closer to red, the higher the luminous efficiency. Therefore, the first LED 11 that lights yellow and the second LED 13 that lights red
And, the second LED 13 has higher luminous efficiency. Therefore, when power is supplied to both the first LED 11 and the second LED 13, the red brightness of the second LED 13 increases, and the first LED 11 is almost turned off.
As a result, there is also an advantage that it becomes easier to visually confirm submersion of the float body 17.

Although the first LED 11 which emits yellow light and the second LED 13 which emits red light are used in the above embodiment, the present invention is not limited to this. For example, the first LED which emits yellow light and the green light which emits green light are used. Alternatively, the first LED that emits light red and the second LED that emits light red may be used. In particular, when the first LED and the second LED that emit the same color are used, the light-transmitting portions of different colors are formed in the float body 17, and the light of the first LED and the light of the second LED are emitted through this light-transmitting portion. Just do it.

Further, although the electric float of the present invention is applied to the electric float for fishing in the above embodiment, the present invention is not limited to this and may be applied to, for example, a buoy. In the case of this configuration, a movable float that moves relative to the buoy body is provided, and as the movable float moves according to the ebb and flow of the tide, only the first LED is energized, or both the first LED and the second LED are energized. Will be done.

[0026]

As is apparent from the above description, the electric float of the present invention has the following effects. According to the means described in claim 1, even when the current flows through the second light emitting diode using water as a medium, the second light emitting diode can be kept in the off state while the first light emitting diode is still emitting light. Therefore, erroneous lighting of the second light emitting diode is prevented, and it becomes easy to confirm that the float body is submerged in water. In addition, since the light emitting state can be changed with a simple structure in which a movable float is added, the structure can be simplified and the cost can be reduced.

According to the second aspect of the present invention, since the emission color can be changed according to the degree of submersion of the float body, it is easy to confirm the submersion of the float body. Moreover, since the second light emitting diode can emit light more clearly than the first light emitting diode, it becomes easier to confirm that the float body is submerged in water.
