The present invention relates to a fishing bobber, and more particularly to an electronic fishing bobbin for night fishing using a multi-pole magnet.

Conventional night fishing floats have to maintain a substantial buoyancy in order to float heavy gear, such as bait, rods and fishing needles, so they must have a body of a certain volume and a single indicator light to confirm the position of the bobber. Kerryite or red diode light emitting device). However, this type of fishing bobber had a very large diameter on the center, which could be applied depending on the wave shape.

In order for the bobber to react sensitively to small fishing boats, the maximum cross-sectional area of the bobber should be as small as possible and placed perpendicular to the water surface. However, there is a considerable distance between the shape basically required in conventional teeth and the efficient function of the original teeth. In particular, in order to detect fishery on a constantly changing wave with this conventional form of steam, the process of catching water into water had to be constantly observed. That is, the observer had to identify the difference between the movement of the bobber and the movement by the fisherman.

However, due to visual errors and ambiguity in the perception of the movements of the tailings caused by the movement of wind and waves, the preparation and the sticks of the sea, and the fishery, the fishers have a large change in the length of the exposed tailings. When the fish was raised, that is, when the fish were submerged, the fish had no choice but to detect them, especially when the fish were caught on the reef.

An object of the present invention is to provide an electronic fishing bobber resistant to unnecessary external force.

Still another object of the present invention is to provide an electronic fishing bobber that is strong against unnecessary external force and can arbitrarily condition buoyancy.

Still another object of the present invention is to provide an electronic fishing bobber that is strong against unnecessary external force and can arbitrarily adjust buoyancy and can easily catch fishing fish.

In addition, the present invention has various objects, but this object is gradually described according to the description of the present invention.

The object is to form a space therein to achieve a buoyancy body and the body having a hole in the upper and lower; A watertight membrane for dividing the space constituting the body into an upper vacancy and a lower vacancy; In the lower vacancy of the body, the upper end is located close to the watertight membrane and the opposite lower end is extended to protrude out of the body through the lower hole of the body, the multi-pole magnet is attached to the upper end near the watertight membrane, The lower end of the outer body and fishery fishing rods are connected to the fishing line; A spring inserted into the fishery sensing rod in the lower vacancy to force the fishery sensing rod to an upper side by an elastic force; In the upper vacancy of the body, a lower switch near the watertight membrane is attached to the lead switch which is operated by the fish pole sensing rod and the multipole magnet, and the upper end extends through a hole in the upper portion of the body to be exposed to the outside. Jigsaw assembly; It is achieved by an electronic fishing bobber which is attached to an external exposed portion of the jig assembly and consists of a display means operated by the lead switch.

The operation of the invention having such a structure is briefly described as follows.

The fishing bobber is tied to the fishing line extending from the fishing rod along with the fishing needle, and the bait is fitted to the fishing needle. The fishing line is tied to the bottom exposed to the outside of the fishing rods, one of the components of the bobber.

The spring, which is inserted into the fishery sensing rod in the lower chamber of the body and presses the fishery sensing rod to the upper side by the elastic force, controls the displacement amount of the fishery sensing rod by its elastic modulus to set the relative displacement of the multipole magnet and the lead switch. That is, when the force to pull the fishery sensing rod is below a certain value, the relative displacement of the multipole magnet and the lead switch is reduced so that the lead switch does not operate.When the force is above a certain value, the relative displacement of the multiple magnet and the lead switch is determined by the lead switch. Make it workable.

At this time, the external force generated by waves, air volume, and algae and the force of pulling fishery rods by the force when the meat bites the bait are different, so the compressive force acting on the spring by the external force and the meat bite the bait. There is a critical point between the compressive forces acting on the spring when pulling.

That is, it is caused by various external forces such as waves, air volume, and tidal current, and the force applied to the spring is below a certain limit so that the fish finder rod cannot be pulled downward or the relative displacement of the multipole magnet with respect to the reed switch can be It is not enough to change the state of the switch, thereby avoiding malfunctions caused by external forces other than fishery.

On the other hand, when the fish bites the bait, the fishing line is pulled by the force of the meat pulling the bait, and the force to pull the fishing line is transferred to the fishery sensing rod to pull down the fishery sensing rod. At this time, the force applied to the spring is pulled downward, the force applied to the spring is more than the specified value, the displacement amount of the lead switch attached to the fishery sensing rod becomes more than the specified value. This displacement amount is more than a threshold sufficient to fluctuate the state of the lead switch by the multi-pole magnet, which causes the state of the lead switch to fluctuate. As the state of the lead switch changes, the displacement is located on the external exposed part of the jig assembly and connected to the lead switch. The display state of the display means is changed.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

First, referring to FIG. 3, the roughly hemispherical top cover 1, which is made of a synthetic resin material, is formed in the shape of a truncated cone, extending in a cylindrical shape and having a hole in the lower part. It is coupled to the body 2 and the adhesive or screw to form a buoyancy body forming a space therein.

The watertight membrane 5 is fitted to the cylindrical part of the body, and the watertight membrane 5 clearly separates and blocks the space part of the body into the upper chamber 13 and the lower chamber 13 'so that sea water seeps into the space part. It does not lift and maintains the exact buoyancy required for the float to float on the surface of the water. In addition, the upper diameter of the watertight membrane is equal to the inner diameter of the sealant effect, and the lower diameter of the watertight membrane is smaller than the inner diameter of the body so that the downward recessed portion is formed in a stepped shape. 4) It was able to move up and down exactly in the vertical direction. In particular, the watertight film 5 has a structure in which the electronic circuit located in the jigsaw assembly 3 is completely inserted into the cylindrical portion of the body 2 and adhered with an adhesive to prevent corrosion due to exposure to sea water. Therefore, it is particularly preferable to produce the watertight film 5 from a solid synthetic resin. In addition, the buoyancy can be arbitrarily adjusted by allowing the position of the watertight film 5 to be adjusted as a preferred embodiment.

The fishery detection rod (4) having a fishing line connected to the outer lower end to detect the meat biting the bait extends so that the lower end protrudes outward from the lower vacancy (13 ') of the body through the lower hole of the body (2). And the upper end of the fishery sensing rod located in the lower chamber 13 'is smaller than the diameter of the body 2 and larger than the diameter of the recessed portion of the watertight membrane 5 so that the recessed portion of the watertight membrane 5 described above can be inserted. The concave inlet portion is formed, and a multiple magnet is attached to the upper end of the concave portion of the fishery sensing rod 4, and is arranged to drive the lead switch of the jigsaw assembly described below. In particular, the fishery sensing rod 4 is smaller than the diameter of the indentation portion of the fishery sensing rod from the upper protruding jaw 16 immediately below the recessed portion of the fishery sensing rod to the lower protruding jaw 17 below, and is less than the lower hole of the body 2. It extends to a large diameter of the first diameter, and extends from the lower protrusion jaw 17 to approximately the lower hole of the body 2 with a second diameter smaller than the diameter of the lower hole of the body 2. The spring 11 is inserted and restrained in the lower chamber 13 'between the portion having the first diameter and the portion having the second diameter of the fishery detecting rod 4 and the lower hole of the body 2. The portion having the second diameter in the fishery sensing rod 4 so that the lower protruding jaw 17 of the fishery sensing rod 4 does not pass through the lower hole of the body even when the fishery sensing rod 4 is pulled downward with a large force. It is pulled by the length of and no longer pulled.

In addition, the fish sensing rod (4) is located in the vertical position exactly, when the fishing bobber is thrown into the fishing line and throwing the gear, the fishery sensing rod (4) is rotated separately from the body, the fishery sensing rod (4) V-shaped groove 18 is dug at the bottom of the body 2 to prevent it from being twisted by being wound at the lower end of the body.

The jig saw assembly 3 extends and protrudes from the lower end located in the recess of the watertight film 5 in the upper chamber 13 inside the body 2 to the outside through the hole of the upper cover 1 of the body. The lead switch (7) is attached to the bottom of the jig saw assembly located in the concave part of the watertight membrane (5) and is driven by the multi-pole magnet (6) located at the upper part of the concave part of the fishery detecting rod (4). On the part exposed to the outside through the upper hole of the top cover 1, the light emitting diodes of the display means are attached.

The electronic circuit for operating the light emitting diodes is inserted into the jigsaw assembly 3 and is modeled and integrally formed, and in particular, the jigsaw assembly 3 for easily inserting the battery 10 into the jigsaw assembly 3. The lead switch 7 is attached and extends upwards, forming an L-shape from the lower end inserted into the recess of the watertight membrane 5, and the upper chamber 13 of the body 2 lights up. In order to prevent the top cover is coupled to the screw form (20), the battery 10 is inserted into the battery case 15 located on the top of the jig saw assembly (3).

The display means mounted on the externally exposed portion of the flyback assembly 3 consists of a red diode light emitting opening 27 and a green diode light emitting opening 28, which is described later. In the first state of the lead switch 7 (assuming this first state is a state in which the lead switch 7 is turned off), it is always turned off and the second state (this state is the state in which the lead switch 7 is turned on). Is turned on, the green diode light emitting bulb 28 is always turned on in the first state of the lead switch 7 as opposed to the red diode light emitting bulb 27, and turned off in the second state.

Referring to the operation of the present invention having such a structure is as follows.

4 is shown to explain the operating principle of the spring 11 and fishery detection rod (4). As shown in FIG. 4, the fishing bobbin and the fishing rods 4 are morphologically separated from the conventional fishing bobbin. Therefore, in such a structure, a state displacement occurs between the body 2 of the fishing bobber floating on the water surface and the fishery sensing rod 4 according to the strength and strength of the fishery, and this displacement is a high sensitivity fishery sensing function pursued by the present invention. To make it possible.

The total relative displacement generated by the fishery is divided into non-operating displacement and working displacement. The relative displacement in the non-operating displacement zone is operated by various external forces before the fishery uses it, for example waves, wind direction, tidal currents and body ratios. It is a displacement generated by the force applied to the spring 11, and the relative displacement amount in the working displacement section is a displacement amount applied to the spring 11, which is generated according to the strength of the pure fishery and the movement of the fishery. In this case, there must be a non-operational displacement to avoid malfunction in the real night fishing situation.

In the present invention, only the operating displacement section, the light is moved from the green light emitting bulb 28 to the red light emitting bulb 27 to check the position of the bobber in the circuit.

This principle can be expressed as a relation between the total relative displacement amount, the proportional constant of the spring 11 and the maximum cross-sectional area of the fishery sensing rod 4. As shown in FIG. 4, the equilibrium in the non-operational section before the fishery is detected in the state where the whole float is submerged is the force F ₁ exerted on the spring by the relative displacement Δy ₁ in the non-operational section.

F ₁ = k △ y ₁ (1)

This is where k is a spring constant in this state, the eosin by force exerted by the spring by operating the relative displacement △ y ₂ in the operating section F ₂ is acting

F ₂ = k △ y ₂ (2)

Becomes Meanwhile, reaction force F ₃ against buoyancy due to △ y ₂

F ₃ = γAΔy ₂ (3)

Γ is the specific gravity of water, A is the maximum cross-sectional area of the fishery detection rod (4). Since the relationship of F ₂ = F ₃ is established, the following equation can be derived.

kΔy ₂ = γAΔy ₂

or

k = γ A

Becomes In the above equation (4), γ is a constant as the specific gravity of water, so the maximum cross-sectional area A of the fishery detecting rod 4 is proportional to the spring constant k. Here, when the spring constant k is reduced, the maximum cross-sectional area A is also reduced, so that a highly sensitive fishery detection system can be constructed that can detect the same relative displacement even at a small force.

In the present invention, the body weight (rods, fishing needles, moss) detached from the bobber under normal weather conditions in which waves with an amplitude of 1-2 m and a wavelength of 1.5 m-2 m are pushed at a speed of 1-2 m / sec is 2- In the case of 2.5 kg, the maximum force F that can be received in the non-operating section of the spring 11 of the bobber is when the bobber rises to the maximum height of the wave and the direction of the subalgae to the speed of the wave is in the opposite direction. In this case, the speed of the tidal current and the speed of the waves are almost constant velocity, so the force applied to the spring is weak. Relative acceleration of the tail body (2) is 1-2m / sec, so the maximum value of F is the force of 4-5g.

In the case of the present invention, the non-operational section displacement is 4-5mm, but the maximum 5mm or less red diode light emitting port 27 is not lit, the spring constant value is 0.8-1.25g / mm. In the case of the present invention, the displacement of the operating section was set to 1-1.5mm, which was based on the contact forming section of the lead switch 7 and the multi-pole magnet 6.

Then, when there is no more relative displacement between the tail body 2 and the fishery sensing rod 4 in the state where the light is moved to the red diode light emitting device 27, the multi-pole magnet 6 has a lead switch ( 7) There is a problem that the red diode light-emitting port 27 that is turned off is turned off again because it goes down below the contact point. Therefore, in the present invention, once the fishery is sensed and the light is turned on the red diode light emitting device 8, the red diode light emitting device continues when the premise body is submerged into the water by the force of the meat or when the angler lifts the gear. In order to maintain the state in which the light of (27) is turned on, a lower stopper 12 is installed on the fishery detection rod 4 to prevent relative displacement above the total relative displacement amount indicated by the present invention. It was.

Above, it should be configured so that the contact of the lead switch 7 can be accurately formed in the operating section with respect to the entire relative displacement of the fishery detection rod 4 described above. To this end, as shown in FIG. 4, a system is constructed using the multi-pole magnet 6 and the lead switch 7. In the non-operational section, the multi-pole magnet 6 is positioned above the lead switch 7 so that the contact of the lead switch 7 is not formed, and then the contact of the lead switch 7 is formed when moving to the operation section. . In this structure, the contact point of the lead switch 7 is formed according to the strength of the magnetic field, the shape of the magnet, and the horizontal and linear distances with the lead switch 7. In the present invention, since the difference between the horizontal distance (3.75mm) and the linear distance (6.25mm) between the multi-pole magnet 6 (cylindrical magnet of 7.5 mm) and the lead switch 7 is small, the magnetic field strength exceeds a certain law. If a value has a value, a contact of the lead switch 7 may be formed in the non-operating section, and in order to avoid it, a contact of the lead switch 7 may not be formed even in the operating section when the strength of the magnetic field is reduced. May occur. Therefore, in the case of a product having high sensitivity, stability and cracking degree required in the present invention, the contact point of the lead switch 7 at the position (operation section) in which the magnet is multi-stimulated, that is, the multi-pole as shown in FIG. Is formed. That is, the circuit of the relative detection (Δy ₂ ) of the fishery detection rod 4 by the fishery induces a magnetic field change to the contact portion of the lead switch 7 made of magnetic material. A circuit constructed as described above is shown in Fig. 5A. When the bobber is in equilibrium on the water surface at night, the green diode light emitting hole 28 is semi-reflected to confirm the position of the bobber to the angler, and when the contact point of the lead switch 7 is formed, the green diode light emitting hole ( 28 is turned off, and the red diode light-emitting port 27 is turned on. A battery saving resistor 19 is connected in series to a positive pole of a battery having internal resistance, and one pole of the green diode light emitting opening 28 having a high emission start voltage in the forward direction is connected to one side of the battery saving resistor 19. The other pole of the green diode light bulb 28 is connected to the negative pole of the battery, and always emits green light. One pole of the red diode light-emitting port 27 (low emission start voltage) is connected to the battery (-) pole in the forward direction, the other pole is connected to one side of the lead switch 7 and the other side of the lead switch 7. Is connected to the positive pole of the dry cell, and the circuit is not normally turned on. Therefore, the red diode light-emitting port 27 is not turned on. When the contact of the lead switch 7 is formed by the multi-pole magnet 6, the red diode is then The light emitting hole 27 is directly connected in parallel with a battery having an internal resistance, so that a voltage drop occurs in the internal resistance of the battery due to the current flowing in the red diode light emitting device 27, and thus, the output voltage between the battery terminals is reduced. For this reason, the green diode light emitting port 28 whose light emission starting voltage is higher than the start voltage of the red diode light emitting port 27 is naturally turned off. The intensity I _G of the current in the green diode light-emitting port 28

I _G = (V _O _ V _G ) / (R ₁ -R _S ) (5)

Is given by Where V _O is the voltage of the battery, V _G is the voltage of the green diode light emitting opening 28, R ₁ is the battery internal resistance, and R _S is the battery saving resistance 19. According to the size of R _S , the brightness of the diode light emitting port is reduced and at the same time, battery consumption is also reduced.

The internal resistance R ₁ of the battery is a new one when makes it more and more blurred the diode light-emitting sphere because it increases as it was a value that is used over time according fire while when attached by selecting the appropriate external resistance R _S (19) use the The change in brightness can be reduced and the battery can be used for a longer time by reducing the consumption of battery drugs.

When the lead switch is turned on, the circuit is shown in Fig. 5 (B).

(I _R + I _G ) R ₁ + V _R = V _O (6)

V _R = R _S i _G + V _G (7)

(I _R + I _G ) R ₁ + R _S I _G + V _G = V _O (8)

Becomes Where I _G is the strength of the current in the green diodes 28, I _R is the strength of the current in the red diodes 27, R _l is the internal resistance of the battery, R _S is the external resistance for saving the battery, and V _O is The voltage of the battery, V _R is the voltage of the red diode light-emitting port, V _G is the voltage of the green diode light-emitting port 28. Here, the forward voltage drop in the diode light emitting sphere is related to the material of the light emitting material. In the present invention, GaP is used for the green diode light emitting device 28 and GaAlAs is used for the red diode light emitting device 27, and forward pressure at this time is 2.1V (green LED lamp) and 1.7V (red LED lamp), respectively. Since V _R is less than V _G in Eq. (7), the value of I _G must have a negative value, but it is substantially close to zero.

Substituting this in equation (6),

I _R = (V _O -V _R ) / R _l (9)

As a result, only the red light emitting diode (red LED lamp) shines brightly.

As described above, according to the present invention, the multi-pole magnet 6 which responds to the fishery as the electronic fishing bobber for night fishing opens and closes the lid switch 7 so that the green-dyed light emitting hole 28 for checking the position of the fish and red for fishery confirmation Since the lighting state of the dyed light bulb 8 is replaced, anyone can easily catch the fish during the night fishing, and even when the fishing gear is caught on the reef or the grass, it is easy to identify with the fish. There is an adaptable effect.

In addition, since the spring used in the present invention is configured to control the operation section displacement and the non-operation section displacement, it is possible to prevent external operation by external force other than fishery, and to use the lid switch 7 to operate the opening and closing. Since the magnet is a multi-pole magnet (6), the lighting state is replaced at the correct position, and the fishery sensing rod (4) for detecting fishery is separated from the fly body (2) to enable the fishery sensing function. Since the external resistor for saving battery is attached, it not only extends the life of used batteries but also keeps the brightness of fire constant during use.
