[Industrial Application Field] This invention relates to a switching device using a permanent magnet, and more specifically, the contacts of a reed switch installed in close proximity are turned on and off by the vertical movement of a floating magnet. The present invention relates to a switch device, and more particularly to a fishing float to which this switch device is applied.

2. Description of the Related Art Conventionally, switch devices have been devised that utilize reed switches and permanent magnets to drive light-emitting devices such as lamps on and off. That is, the Republic of Korea's utility model publication number 88-361
As described in No. 5, a fishing float is equipped with a permanent magnet that moves according to the movement of the floating body, and two reed switches that operate in conjunction with these magnets are installed, and each reed switch is activated by the movement of the floating body. There is a known technique in which a switch device is turned on and off, and a lamp is driven to blink as the switch turns on and off.

However, in the case of the above fishing float,
The accuracy of the switch device is such that the floating rod moves due to external forces (wind, waves) that are not caused by fish hitting, causing malfunctions that cause the lamp to blink, and the disadvantage that the lamp does not blink when the floating rod rises. There was an inconvenience that the operation could not be expected.

0004

SUMMARY OF THE INVENTION In view of the above circumstances, it is an object of the present invention to provide a switch device and a fishing float that can be expected to operate accurately.

[0005]

[Means for Solving the Problems] In order to solve the above-mentioned problems, a switch device using a permanent magnet according to the invention according to claims 1 to 3 is provided, for example, as shown in FIG. The floating magnet 1 and the fixed magnet 5 installed at the bottom are arranged so that the same poles correspond to each other, and the contact 4 of the reed switch 6 is placed close between them, and by moving the floating magnet 1 in the vertical direction, the reed switch 6 The configuration is such that the drive is performed. By making the floating magnet 1 have the same polarity as the fixed magnet 5 installed at the bottom,
It maintains a levitated state at a certain distance from the reed switch contact 4 due to repulsive magnetic force.

That is, as shown in FIG. 3, the lower fixed magnet 5 is fixed to the outside of the reed switch protection tube 9 so as to be located slightly below the limit line C of the contact 4 of the reed switch 6, and the fixed magnet 5 is If the floating magnet 1 is placed in the switch cap 8 so that the same poles (N poles) as in 5 correspond to each other so that only vertical movement (up and down direction movement) is possible, the same N poles will push against each other. The repulsive magnetic force A acts to cause the upper floating magnet 1 to float slightly above the contact limit line B that causes the reed switch contact 4 to close.

Furthermore, in the invention as claimed in claim 2, as illustrated in FIG. 2, the floating magnet 1 of the switch device is suspended by a spring 2 that adjusts the strength of the influence of the impact to control the movement of the floating magnet. According to the third aspect of the invention, the fixed magnets are installed above the floating magnet of the switch device so that the fixed magnets have different poles corresponding to each other, so that the movement stroke of the floating magnet can be increased.

Further, as shown in FIG. 3, a load can be connected to the reed switch 6 and the load can be driven in conjunction with the operation of the reed switch 6. In order to solve the above problem, a fishing float according to the invention according to claim 4 has a light emitting device that blinks when driven by a reed switch, and a switch device according to any one of claims 1 to 3. The floating magnet is located at the top of the float, and the fixed magnet is located at the bottom.

[0009]Furthermore, the fishing float according to the invention set forth in claim 5 is provided with the switch device set forth in any one of claims 1 to 3 such that the floating magnet is located at the upper part and the fixed magnet is located at the lower part. A transmitting device is installed inside the device and outputs a wireless signal by driving the reed switch of the switching device, so that the alarm device can generate an alarm sound at a remote location. In this case, as in claim 6, it is preferable to also have a light emitting device that blinks when driven by a reed switch. In addition, the transmitting device may include, for example,
According to a seventh aspect of the present invention, a transmitting circuit is provided which includes a low frequency oscillation section, an FM oscillation section that inputs the output of the low frequency oscillation section, and a high frequency amplification section that amplifies the output of the FM oscillation section.

[Operation] When the switch device of the present invention constructed as described above is pulled downward, the switch body 10 moves downward, so that the distance between the fixed magnet 5 and the floating magnet 1 increases. When this happens, the repulsive magnetic force A that was acting between the two magnets becomes weaker, so the floating magnet 1 descends due to its own weight by a distance greater than the distance that the fixed magnet 5 has descended, and its magnetic force is reduced. Since the contact point 4 of the reed switch 6 is closed (turned ON), the connected load is driven.

At this time, a certain repulsive magnetic force is re-formed between both magnets, so the floating magnet 1 returns to its original position.
At the same time, contact 4 of reed switch 6 will open (O
FF). The switch device of the present invention configured as described above operates in the same way when pulled upwardly as when pulled downwardly.

That is, when the switch device is raised vertically, the switch body 10 momentarily moves upward while the floating magnet 1 remains stationary, so that the magnetic force of the floating magnet 1 is applied to the reed switch 6 and the reed switch 6 is closed (turned ON), and the connected load is driven. At this time, a certain repulsive magnetic force is re-formed between both magnets, so the floating magnet 1 returns to its original position, and at the same time, the contact 4 of the reed switch 6 opens (OFF
do).

[0013] When a switch device based on such a principle is applied to, for example, a fishing equipment such as a float (fishing float), accurate operation can be expected in response to a fish hit, and the enjoyment of night fishing can be further enjoyed. You will also be able to do this. That is, if the switch device of the present invention is installed inside a float and a light emitting device driven by a reed switch is provided, the switch will be activated not only when the float body is pulled downward, but also when it floats above the water. The reed switch of the device is turned on
At the same time, the light-emitting device starts blinking, making it possible to clearly see the fish hit from a long distance, even at night.

If the float is equipped with a transmitting device that outputs a wireless signal by driving a switch device and a reed switch, it will be possible to detect not only when the float body is pulled downward but also when it floats above the water. A signal is emitted from the transmitting device at the same time as the reed switch of the switching device is turned on, and this signal is received by a known alarm device carried by the angler and detected by an alarm sound, etc. You can clearly see the fish hit from a distance. It is more preferable if a fish hit can be detected by both the flashing of the light emitting device and the alarm sound.

Furthermore, as shown in FIG. 2, in the case of a switch device suspended by a spring 2 that adjusts the strength of impact on a floating magnet, if this is applied to a float, it will cause severe waves or strong winds. In the case of blowing, if you adjust the spring 2 to increase the distance between the floating magnet 1 and the boundary line B of the contact point, the sharp movement will be slowed down, and the fish will not be activated by the influence of waves or wind. Only hits can be reliably detected.

[0016] Furthermore, if another fixed magnet with a different polarity is installed above the floating magnet (placed so that the poles of different polarity face the floating magnet and mutual attraction acts on each other), a minute impact may occur. It is also possible to obtain a switch device that operates sharply. When this switch device is applied to a fishing float, it becomes possible to drive the reed switch even if the float moves slightly due to a minute hit by a fish, making it possible to reliably sense a minute hit by a fish.

In other words, when the float moves slightly due to a minute contact, the distance between the floating magnet and the upper fixed magnet becomes shorter, and as a result, an attractive force acts, and eventually the free distance between it and the lower fixed magnet ( Since the levitation magnet can maintain a sufficient descending distance (motion stroke) due to its own weight, the reed switch can be driven even by a minute fish hit. be.

[0018]

[Embodiments] Examples of the present invention will be described below. FIG. 1 shows the main configuration of an embodiment of a switch device according to a first aspect of the present invention. This switch device is composed of a fixed magnet 5 with a reed switch 6 provided inside and a floating magnet 1 floating above the fixed magnet 5. The contact 4 of the reed switch 6 is connected to the fixed magnet 5 and the floating magnet. 1, and the lower fixed magnet 5 is supported by a resilient spring 3 fitted in the switch body 10. Both the floating magnet 1 and the fixed magnet 5 are permanent magnets.

The polarities of the facing magnetic poles of the floating magnet 1 and the fixed magnet 5 are the same, and the repulsive magnetic force generated between the floating magnet 1 and the fixed magnet 2 causes the magnet to levitate at a certain distance from the contact 4 of the reed switch 6. The condition is maintained. That is, as shown in FIG. 3, the lower fixed magnet 5 is fixed to the outside of the protective tube 9 of the reed switch 6 so as to be located slightly below the limit line C of the contact 4 of the reed switch 6, and the floating magnet 1 is If the fixed magnet 5 and the same magnetic poles (N poles) are placed in the switch cap 8 so that they correspond to each other so that only vertical movement is possible, the repulsive magnetic force A that pushes the same N poles together will act and move them upward. The floating magnet 1 floats slightly above the limit line B that closes the contact 4 of the reed switch 6.

FIG. 2 shows the main structure of an embodiment of the switch device according to the second aspect. In the case of the switch device shown in FIG. 2, as shown in FIG. 2, the floating magnet 1 is suspended from a spring 2 that adjusts the strength of the impact to control the movement of the floating magnet 1, and a screw 7 that adjusts the elasticity of the spring. A spring is connected to the terminal, and the distance between the floating magnet and the limit line of the contact point can be changed by adjusting the screw 7.

FIGS. 4 to 6 show the main structure of a fishing float to which an example of the switch device of claim 2 is applied. That is, as shown in FIGS. 4 to 6, the floating rod 1 inside the floating body 11
A ring-shaped fixed magnet 5 and a floating magnet 1 are installed on the outer surface of the LED 2, and a reed switch 6 is installed in close proximity between them to form a switch device.
ED2 is placed at the tip.

When a fish hits underwater, for example, the floating body 11 is pulled in and lowered in the vertical direction, so the floating magnet 1 is lowered and the contact 4 of the reed switch 6 is closed, as shown in FIG. As such, the voltage of the battery 13 is applied to the light emitting device LED1, turning it on (ON). At this time, the light emitting device LED2, which has always been turned on through the resistor R, is turned off.

[0023] Then, since a repulsive magnetic force is re-formed between both magnets 1 and 5, the contact 4 of the reed switch 6 opens.
The light emitting device LED1 is turned off (OFF). On the other hand, the light emitting device LED2 returns to the constantly lit (ON) state. In other words, each time a fish makes a hit, the light emitting device flashes, making it possible to clearly see the fish's hitting action from a long distance, even at night.

[0024] Also, when the float main body 11 is hit by a fish floating on the water, the light emitting devices LED1 and LED2
flashes. That is, when the floating body 11 rises due to a fish hitting, the floating magnet 1 is stopped and the fixed magnet 5 is instantaneously moved.
As the side rises, the contact 4 of the levitation magnet 1 and the reed switch 6 approach each other, and the magnetic force of the levitation magnet 1 causes the contact 4 of the reed switch 6 to close, and as in the case above, the light emitting device L
ED1 and LED2 blink.

Furthermore, since the floating magnet 1 is installed by connecting the spring 2 that adjusts the strength of the impact to the screw 7 that adjusts the elasticity of the spring 2, the floating magnet 1 is installed in such a way that the spring 2 that adjusts the strength of the impact is connected to the screw 7 that adjusts the elasticity of the spring 2. Even if it blows, if you adjust the screw 7 to make the distance between the floating magnet 1 and the limit line B of the contact point 4 longer, the sharp movement will become slower and you will not be affected by waves or wind, and you will only be able to accurately hit the fish. Can be sensed.

FIGS. 7 and 8 show that above the floating magnet 1,
Another fixed magnet 15 is installed (installed so that the polarity is different from that of the floating magnet so that mutual attraction acts), and an example of a sensitive switch device (switch device according to claim 3) that is activated even by a minute external impact is installed. This figure shows the main structure of the fishing float installed. Fixed magnet 15 is a permanent magnet. Explaining according to FIGS. 7 and 8, even if the float 11 moves slightly due to a slight hit by a fish, the distance between the floating magnet 1 and the fixed magnet 15 above becomes shorter, and as a result, an attractive force acts and eventually Since the upward separation distance (movement stroke) from the fixed magnet 5 at the bottom becomes larger, a sufficient downward distance (movement stroke) due to the weight of the floating magnet 4 can be ensured, and the fine contact movement The reed switch 6 also comes into operation.

An unexplained number 16 in FIG. 7 is a round ring 1 for fixing the fixed magnet 15 installed on the upper part.
7 is a round ring for limiting the lifting distance of the floating magnet 1, and 18 is a round ring for fixing the fixed magnet 5 installed at the bottom of the reed switch 6. Note that the floating magnet 1 may be guided by the inner surface of the cap 8 as shown in FIG. 1, or guided by the outer surface of the floating rod 12 as shown in FIG. If this is allowed, stable operation can be expected because the floating magnet 1 will not move irregularly.

Next, another embodiment of a fishing float will be described with reference to FIGS. 9 and 10. When the switch device of the present invention is installed on a fishing float and a transmitter is connected thereto, the angler can immediately sense the hit of a fish as an alarm sound generated by a known alarm device. In conjunction with the actuation of the reed switch due to a fish hit, a transmitter sends out a radio signal (wireless signal) to notify the fish hit, which is received by an alarm device carried by the angler and converted into sound, for example, to alert the fish hit. It teaches anglers what they need right away.

That is, the transmitter, which operates in conjunction with the connection operation of the reed switch contact 4 installed inside the floating body 11, is composed of a low frequency oscillation section 21, an FM oscillation section 22, and a high frequency amplification section 23, and is integrated. It has a circuitized transmission circuit TC. FIG. 10 is a circuit diagram of the transmitting circuit TC. Note that the unexplained number 14 in FIG. 9 is a cushioning material. Note that, for example, the fishing float shown in FIG. 5 may also be provided with the cushioning material 14.

In the low frequency oscillation section 21, a transistor T is connected to a power supply line (power supply line) led through a resistor R11.
The base of R1 is connected via a base resistor R1, and the emitter of transistor TR2 is directly connected.Furthermore, a capacitor C1 is inserted and coupled between the emitter and collector of transistor TR2, and the base of transistor TR1 and transistor TR2 are connected. A capacitor C2 is inserted and coupled between the collector and the collector.

In the FM oscillation section 22, the transistor TR3
The collector of the transistor TR2 is connected to the base of the transistor TR2 through a capacitor C3, and the power line is connected through a resistor R4.The collector of the transistor TR3 is connected to the power line through a coil L1, and the capacitor C5 is connected to the coil L1. connected in parallel. In the high frequency amplification section 23, the base of the transistor TR4 is connected to the power supply line via a capacitor C9 and a capacitor C8, a resistor R7 is inserted and coupled between the base and collector of the transistor TR4, and the collector of the transistor TR4 is connected to a coil. L2
capacitors C10 and C11 are connected between the collector of transistor TR4 and the power supply line.
are connected and connected in series.

By configuring the transmitting circuit TC in this manner, when the float body 11 is lowered due to a fish hitting and the reed switch 6 is turned on, the voltage of the battery 13 is simultaneously applied to the transmitting circuit TC. A signal is output and emitted as described below, and this signal can be received by an alarm device to generate an alarm sound. When the reed switch 6 is turned on, charging of the capacitor C1 proceeds through the resistor R11, the emitter voltage of the transistor TR2 increases, and at the same time, the emitter voltage of the transistor TR2 increases through the resistor R1.
A base current flows through 1.

This base current constitutes the collector current of transistor TR2. This collector current is flowing through resistor R3, thereby increasing the collector voltage. The increased voltage results in a current flowing through the positive feedback capacitor C2, which together with the current flowing through the resistor R1 forms a bias current. Therefore, a phenomenon occurs in which the bias current increases and the charging current IC2 also increases. In this state, the power supply cannot sufficiently supply the emitter current of the transistor TR2 flowing through the resistor R11, so the electric charge stored in the capacitor C1 is discharged and the emitter voltage of the transistor TR2 starts to decrease. The charging current decreases.

In this state, the base current of the transistor TR1 decreases through the capacitor C2 (the charge stored in C2 is discharged), and the current flowing to the base of the transistor TR1 through the resistor R1 decreases through the capacitor C2.
This is used as a discharge current for transistor TR1 and inhibits the operation of transistor TR1. This phenomenon inhibits the operation of transistor TR2, and positive feedback is applied again, causing transistors TR1,
Stop the operation of TR2. This state is the same as when power is initially supplied, and the time constant is mostly proportional to the sizes of the capacitor C1 and the resistor R3, and inversely proportional to the sizes of the resistor R11 and the capacitor C2.

When the signal input from the low frequency oscillator 21 through the capacitor C3 is a positive current, the collector current of the transistor TR3 flows in order to turn on the transistor TR3, and at this time, the parallel connection between the coil L1 and the capacitor C5 A current corresponding to the resonant frequency is sent as a signal to the emitter of transistor TR3. This signal is sent to the high frequency amplification section 23, and its waveform is shaped by capacitors C6, C7, etc.

Furthermore, when the current from the low frequency oscillation section 21 stops, the transistor TR3 is turned off and oscillation is stopped. Therefore, the high frequency output is intermittent. The high frequency of the FM intermittent signal input from the FM oscillator 22 is removed by the capacitor C8, and the current is amplified to the same level as the current amplification factor by the self-biased transistor TR4 through the capacitor C9, and then sent to the coil L2 and the capacitor C10.
, C11 into an appropriately shaped wave, and sent to the antenna for transmission. By receiving and sensing this transmitted signal with a known warning device carried by the angler, it is possible to accurately confirm whether the fish has been caught.

[0037]

Effects of the Invention As described above, the switch device of the present invention drives the reed switch (ON, O
Since the FF operation (FF operation) is made sharp, accurate operation can be expected, and appropriate interlocking drive of connected loads is possible.A fishing float to which this switch device is applied operates accurately when a fish hits. It is now possible to effectively and accurately identify fish hits using the flashing lights of the light-emitting device and the warning sound of the alarm device, and it has extremely high practical value, such as making it possible to enjoy night fishing even more. It is an invention.
