Description

Technology Field

[0001] The present invention relates to the field of fishing equipment technology, and in particular to an artificial lure called an egi for catching cephalopods.

[0002] More specifically, the invention relates to a new structure of fishing jig that deviates from the conventional one-piece structure and separates the jig into a head that determines the weight, a body that serves as the central frame, and a slit including a fishing hook, thereby allowing the head to be easily replaced with a different weight depending on the fishing environment, and minimizing the loss of the rig by separating only the slit when snagging on an underwater obstacle occurs. Background Technology

[0004] Recently, fishing jigs have been developed in various forms, but most conventional jigs have an integrated structure in which the head, body, and fishing hook are permanently joined. This structure can cause various inefficiencies and problems for anglers.

[0005] Conventional jigs have a fixed weight, making it difficult to actively respond to real-time changing fishing environments, such as current strength or target depth. To adjust the weight according to changing conditions, anglers had to either purchase and carry multiple finished jigs of different weights or attach additional weights to the jig body. The former incurs a significant cost burden, while the latter compromises the jig's natural swimming posture and reduces the convenience of the rig.

[0006] In addition, due to the nature of Egi fishing, snagging frequently occurs when the hook gets caught on underwater reefs or obstacles. With conventional one-piece Egis, if the rig cannot be retrieved when snagged, the entire Egi, including the relatively expensive head and body, is lost. This not only causes direct financial loss to anglers but also poses a problem where waste Egis containing heavy metals such as lead are discarded into the water, causing marine environmental pollution.

[65535] Korean Patent Publication No. 10-2025-0014827 The problem to be solved

[0008] The present invention aims to provide a modular jig with a new structure in which the jig is configured by separating it into independent parts, such as a head, body, and needle, and each part is organically combined and separated.

[0009] In addition, the present invention aims to provide a function that allows a fisherman to freely adjust the sinking speed and underwater posture of an Egi by quickly and easily replacing various types of heads with different weights and centers of gravity in response to changing fishing environments such as currents and water depths.

[0010] The present invention aims to provide a rig loss prevention structure in which the breaking strength of the connecting member connecting the head and the pin is set lower than the tensile strength of the main fishing line, so that when a snag occurs, the connecting member breaks first, separating only the consumable pin while allowing the expensive head and body to be safely recovered. means of solving the problem

[0012] An eco-friendly Egi equipped with a head replacement and discarding needle function may include a head having a lower sinker formed integrally, a body detachably coupled to the head, a needle provided penetrating the body and including a plurality of fishing hooks at the rear end, and a connecting member having a tensile strength weaker than a fishing line that connects the head and the needle and breaks upon snagging to separate the needle. The head may be characterized by being replaced according to the weight of the lower sinker to adjust the overall weight of the Egi. Effects of the invention

[0014] The eco-friendly Egi equipped with head replacement and discardable needle functions according to the present invention provides significant economic efficiency to anglers. Since anglers can operate a combination of heads of various weights and consumable needles on a single body at a low cost, they can save costs by eliminating the need to purchase multiple expensive finished Egis. In addition, maintenance costs can be drastically reduced because only the needles, rather than the entire Egi, are lost upon snagging.

[0015] Furthermore, the present invention offers excellent convenience and operability. Anglers can maintain an optimal rig by quickly replacing heads to adapt to ever-changing fishing conditions. This provides an opportunity to achieve better results within a limited time and increases fishing efficiency by reducing the time required to re-rig after a loss.

[0016] This invention can prevent the loss of the head, a core component containing heavy metals such as lead, even if rig loss occurs due to snagging. This can dramatically reduce the total amount of waste jigs discarded underwater, thereby helping to prevent marine ecosystems and water pollution. Brief explanation of the drawing

Specific details for implementing the invention

[0019] FIG. 1 is a block diagram illustrating the configuration of an eco-friendly jig equipped with a head replacement and discarding function according to one embodiment.

[0020] In FIG. 1, the Egi (100) may be configured to include a head (110), a body (120), a pin (130), and a connecting member (140). The components and types of the Egi (100) are merely examples and are not limited thereto, and may vary depending on the configuration.

[0021] According to one embodiment, the head (110) may be a component located at the front of the Egi (100) that includes the function of a bottom sinker that determines the sinking speed and underwater posture. The user may selectively replace various types of heads (110) with different weights to suit changing fishing environments, such as the strength of the current or the depth of the target. For example, in environments with fast currents, a heavy head (e.g., 30g) may be used to prevent the rig from drifting away, and in environments with slow currents or shallow depths, a light head (e.g., 15g) may be used to create natural movement. The types of heads are examples only and are not limited thereto, and may vary depending on the settings.

[0022] According to one embodiment, the body (120) serves as the central frame of the Egi (100) and may be a component that structurally connects the head (110) and the needle (130). The body (120) is generally designed to be reusable, and the user can combine various types of heads (110) and needles (130) on a single body (120).

[0023] According to one embodiment, the fishing hook (130) may be a component comprising a plurality of fishing hooks for directly catching cephalopods such as squid or octopus. The fishing hook (130) may be connected to the head (110) side by penetrating the interior of the body (120) and may be a consumable component designed to be detachable to minimize loss of the rig in the event of snagging.

[0024] According to one embodiment, the connecting member (140) is a key component connecting the head (110) and the pin (130). The connecting member (140) may be designed to have a breaking strength intentionally weaker than the tensile strength of the main fishing line. This may be implemented using a material such as a silicone band or a plastic pin of a specific strength. Under normal fishing conditions, the connection between the head (110) and the pin (130) is maintained, but if the pin (130) gets caught on an underwater obstacle and a force exceeding a limit is applied, the connecting member (140) breaks first, separating only the pin (130), allowing the relatively expensive head (110) and body (120) to be recovered. The material of the connecting member is merely an example and is not limited thereto, and may vary depending on the settings.

[0025] According to one embodiment, the Egi (100) may include a head (110) having a lower sinker formed integrally, a body (120) detachably coupled to the head (110), a hook (130) provided penetrating the body (120) and including a plurality of fishing hooks at the rear end, and a connecting member (140) having a tensile strength weaker than a fishing line that connects the head (110) and the hook (130) and breaks when snagged, thereby separating the hook (130). The head (110) can be replaced according to the weight of the lower sinker to adjust the overall weight of the Egi (100).

[0026] According to one embodiment, the Egi (100) may include a head (110) in which a lower sinker is integrally formed. Here, the lower sinker is a part that acts as a weight to induce the sinking of the Egi (100), and can generally be made of a high-density material such as lead or tungsten. The material of the lower sinker is not limited to this.

[0027] The fact that the lower sinker is formed integrally with the head (110) may mean that it is not attached as a separate part, but is manufactured as a single part from the time the head (110) is cast or molded. This can have the effect of providing predictable performance by ensuring that each head (110) has a unique and consistent weight and center of gravity.

[0028] According to one embodiment, the head (110) can be detachably coupled to the body (120). This means a structure that allows a user to combine or separate the head (110) and the body (120) by hand without a special tool. This detachable coupling structure can serve as a basis for enabling the replacement of the head (110), which will be described later.

[0029] According to one embodiment, the body (120) may have a hollow or passage penetrating the interior, and a needle (130) may be provided in the body (120) through this passage. The needle (130) may generally consist of a front end in the form of a long rod and a rear end having a plurality of fishing hooks arranged thereon for capturing cephalopods.

[0030] According to one embodiment, the connecting member (140) may refer to a part that connects the head (110) and the pin (130). The connecting member (140) may be designed to have a tensile strength intentionally lower than that of the main fishing line. For example, when the tensile strength of the fishing line is 10 kgf, the connecting member (140) may be manufactured to break when a force of 3 kgf is applied. This difference in tensile strength induces the connecting member (140) to break first before the fishing line breaks in a snag situation, thereby allowing only the pin (130) to be separated and the remaining parts to be recovered. The connecting member (140) may be implemented in an elastic material such as silicone or rubber, or a plastic pin designed to break at a specific strength. The types of such materials are merely examples and are not limited thereto, and may vary depending on the settings.

[0031] According to one embodiment, the head (110) is replaceable and can perform the function of adjusting the total weight of the Egi (100). The user may have various types of heads (110) with different weights, such as 15g, 20g, and 25g. If it is determined that the current at the site is fast, the user may detach the previously attached 15g head (110) and replace it with a 25g head (110) to adjust the Egi (100) so that it does not drift away in the current and reaches a desired depth layer. The weight of such a head (110) is merely an example and is not limited thereto, and can be set in various ways according to the manufacturer's design or the user's needs.

[0033] FIG. 2 shows a disassembled view of the specific components of an Egi (100) according to one embodiment.

[0034] According to one embodiment, the Egi (100) (e.g., the Egi (100) of FIG. 1) may be configured to include a head (210), a body (220), a needle rod (230), and a silicone band (240) as shown in the drawing. This may be an example of a specific shape corresponding to the head (110), body (120), needle (130), and connecting member (140) respectively shown in the block diagram of FIG. 1.

[0035] According to one embodiment, the head (210) constitutes the front part of the Egi (100), and a lower sinker that determines the sinking speed and weight of the Egi may be integrally formed at the bottom part. The rear of the head (210) has an open structure so that the front part of the body (220) can be inserted and connected. Two types of connecting rings may be formed on the head (210). An upper connecting ring may be located on the outer top to maintain connection with the body (220), and an internal connecting ring may be formed on the inside to be connected to the sinker (230).

[0036] According to one embodiment, the body (220) may have a streamlined body shape, and a hollow may be formed inside through which a needle rod (230) can pass. A lower coupling ring may be provided at the bottom of the body (220) to assist in coupling with the head (210).

[0037] According to one embodiment, the pin rod (230) may include a front connecting ring for connecting to an internal connecting ring of the head (210) at the front, and a pin having a plurality of needles arranged radially at the rear end for capturing cephalopods.

[0038] According to one embodiment, the silicone band (240) may be provided in two types with different sizes and uses. A small silicone band can serve as a connecting member (140). This small band connects the internal connecting ring of the head (210) and the front connecting ring of the pin rod (230), and can serve to break before the main fishing line in the event of a snag, thereby separating only the pin (230). A large silicone band can serve as a coupling member. This large band connects the upper coupling ring of the head (210) and the lower coupling ring of the body (220) by wrapping around them from the outside, thereby serving to firmly secure the head and body so that they do not separate during normal fishing operation. The types and forms of these components are merely examples and are not limited thereto, and can be varied according to the design.

[0039] According to one embodiment, the head (110) may have an internal connecting ring formed therein to which one end of the connecting member (140) is connected, and an upper connecting ring formed therein to which one end of the connecting member is connected. The needle (130) may have a front connecting ring formed therein to which the other end of the connecting member (140) is connected, and the body (120) may have a lower connecting ring formed therein to which the other end of the connecting member is connected. The Egi (100) may further include a connecting member to maintain the connection between the head (110) and the body (120). At this time, one end of the connecting member (140) is connected to the internal connecting ring of the head (110) and the other end is connected to the front connecting ring of the needle (130) to connect the head (110) and the needle (130), and one end of the connecting member is connected to the upper connecting ring of the head (110) and the other end is connected to the lower connecting ring of the body (120) to fix the head (110) and the body (120) from the outside.

[0040] According to one embodiment, each component of the Egi (100) can be combined with each other through connection points formed at specific locations.

[0041] According to one embodiment, the head (110) may include two types of connecting loops. An internal connecting loop may be formed inside the open rear portion of the head (110), that is, at a location that is not directly visible from the outside when combined with the body (120). This internal connecting loop may be a point for attaching a connecting member (140) that performs a separation function when the bottom is caught. An upper connecting loop may be located at the top exposed to the outside, such as the back portion of the head (110), so that a user can easily access and attach the connecting member.

[0042] According to one embodiment, the needle (130) may have a front connecting ring for coupling with a connecting member (140) at a long rod-shaped front end. The body (120) may include a lower connecting ring on its lower surface for connecting with a connecting member. The specific shape of each of these rings may be implemented in various forms, such as a circular hole or a protruding hook, and the illustrated shape is merely an example and is not limited thereto.

[0043] According to one embodiment, the Egi (100) may further include a separate coupling member to physically maintain the connection between the head (110) and the body (120) in addition to the connecting member (140). The coupling member may have physical characteristics different from those of the connecting member (140). For example, if the connecting member (140) is designed to break easily under a specific tension, the coupling member may be designed to have high durability and elasticity so that it never breaks during normal use.

[0044] In this structure, one end of the connecting member (140) may be connected to the internal connecting ring of the head (110) and the other end to the front connecting ring of the needle (130). Through this, an internal connection is formed between the head (110) and the needle (130). Meanwhile, one end of the connecting member (e.g., a large silicone band) may be connected to the lower connecting ring of the body (120) and the other end to the upper connecting ring of the head (110). The elastic tension of this connecting member can serve to strongly compress and fix the head (110) and the body (120) from the outside. The type of connecting member is merely an example and is not limited thereto, and may vary depending on the configuration.

[0046] FIG. 3 is a structural perspective view showing the separated state (310) and combined state (320) of an Egi (100) according to one embodiment.

[0047] According to one embodiment, the separated state (310) may show the appearance of each module constituting the jig (e.g., the jig (100) of FIG. 1) before assembly. The jig (100) may consist of a reusable body, a head that the user can selectively replace according to the fishing environment, and a sinker that is consumed when snagged. The user may select a head from among several types of heads with different weights or shapes that can achieve the desired sinking speed or underwater posture and combine it with one body.

[0048] According to one embodiment, the combined state (320) may show the internal structure of the Egi (100) in which each module is assembled to form a complete shape. The fin penetrates the interior of the body, and the head may be attached to the front of the body. A connecting member (small silicone band), represented by a thin line inside, may connect the inner ring of the head and the front ring of the fin. This may maintain the connection when catching a target fish species, and may break to separate the fin only when a force exceeding a limit is applied due to snagging. A connecting member (e.g., a large silicone band) may firmly fix the head and the body from the outside, allowing the Egi (100) to maintain a stable integrated structure during normal operation.

[0049] Through this coupling structure, the user can easily replace the head by separating the coupling member. This allows the center of gravity and weight of the entire Egi (100) to be changed, thereby allowing the head's inherent sinking speed and tilt angle to be selected according to the situation. In addition, if a snag occurs, the connecting member breaks, separating only the needle, and the relatively expensive head and body can be recovered. This can result in the effect of minimizing economic loss and environmental pollution by sacrificing only the needle, which is a consumable part.

[0050] According to one embodiment, the Egi (100) may be composed of a reusable body (120) having a common coupling structure, a plurality of replaceable heads (110) that are selectively coupled to the body (120) and each have a unique weight and center of gravity, and a consumable needle (130) that penetrates the body (120) and is detachably connected to the head (110). The replaceable head (110) can serve as a weight and balance adjustment module that selects one with optimal weight characteristics from among the plurality of heads (110) and combines it with the body (120) when the user wishes to achieve a specific sinking speed and underwater posture according to the target environment, such as the target depth and current strength. The consumable needle (130) can serve the role of allowing fishing to continue by replacing only the needle (130) while preserving the body (120) and the selected head (110), which are relatively high-value parts, if it gets caught on an underwater obstacle and becomes detached.

[0051] According to one embodiment, the Egi (100) may include a reusable body (120) having a common coupling structure. Here, the common coupling structure means that the front end of the body (120) has a standardized shape and size so that it can be coupled compatiblely with various types of heads (110) of different weights or shapes. The body (120) may be designed to serve as the central framework of such a modular system and to be reusable repeatedly.

[0052] According to one embodiment, the Egi (100) may include a plurality of replaceable heads (110) that are optionally coupled to a body (120) as part of the system. The manufacturer may provide a lineup of heads (110) having various weights, such as 15g, 20g, 25g, etc., and each head (110) may be designed to have a unique weight and center of gravity. All of these heads (110) can be mounted on the same body (120) through a common coupling structure.

[0053] According to one embodiment, the Egi (100) may include a consumable needle (130) that penetrates the body (120) and is detachably connected to the head (110). Consumable means that the needle (130) is designed to be intentionally detached and lost in certain situations, such as snagging. This may be done to protect other parts of higher value by sacrificing the needle (130), which has a simple structure like a fishing hook and can be produced relatively cheaply.

[0054] In this modular structure, the replaceable head (110) can serve as a weight and balance adjustment module. If the user determines that the target depth is deep or the current flow is fast, they can select a heavier one from among the multiple heads (110) and combine it with the body (120). This increases the total weight of the Egi (100) to achieve the desired sinking speed and underwater posture. The weight and type of the head (110) are merely examples and are not limited thereto, and may vary depending on the manufacturer's design or product lineup.

[0055] According to one embodiment, if the consumable fishing needle (130) gets caught on an underwater obstacle and becomes detached, the body (120), which is a relatively high-value part, and the head (110) selected by the user are preserved, and only the fishing needle (130) is replaced to continue fishing. After losing the fishing needle (130), the user can attach a new spare fishing needle (130) to the recovered body (120) and head (110) to resume fishing with minimal time and cost.

[0057] According to one embodiment, the connecting member (140) may be configured to have a breaking strength that is stronger than the force applied during the process of catching a target fish species and lifting it to the water surface, but weaker than the tensile strength of the main fishing line. Accordingly, the connecting member (140) maintains the connection between the head (110) and the pin (130) during the process of catching the target fish species, and only in a bottom-snagging situation where the pin (130) gets caught on an underwater obstacle and a force strong enough to break the fishing line is applied, it may break ahead of the fishing line to separate only the pin (130). The lower sinker formed integrally with the head (110) gives a unique weight to each head (110), so that when a user selects a specific head (110) and combines it with the body (120), the entire Egi (100) may have a predetermined sinking speed and an angle of inclination underwater due to the weight of the corresponding head (110).

[0058] According to one embodiment, the connecting member (140) can be precisely set so that its breaking strength is within a specific range.

[0059] According to one embodiment, the breaking strength of the connecting member (140) may be set to be relatively stronger than the normal force generated during the process of catching a target fish species and lifting it to the water surface, and weaker than the tensile strength of the main fishing line to which the entire rig is connected. For example, if the maximum load generated when a target fish species (e.g., a large cuttlefish) resists is 2 kgf and the breaking strength of the main fishing line is 10 kgf, the connecting member (140) may be designed to break in the range of 3 kgf to 4 kgf, which is a value between them. These values ​​of breaking strength are merely examples and are not limited thereto, and may be set in various ways depending on the target fish species or the type of fishing line used.

[0060] By setting the breaking strength in this way, the connecting member (140) can perform a clearly distinct role in two contrasting situations. First, during the process of successfully catching the target fish species, the applied force does not exceed the breaking strength of the connecting member (140), so the connection between the head (110) and the pin (130) can be maintained stably. On the other hand, in a bottom-snagging situation where the pin (130) gets caught on an obstacle such as underwater rocks or discarded fishing nets and is pulled with a strong force, that force exceeds the breaking strength of the connecting member (140). At this time, the connecting member (140) breaks first before the main fishing line breaks, separating only the pin (130), and the user can safely recover the remaining expensive parts.

[0061] According to one embodiment, a lower sinker formed integrally with the head (110) can serve to provide a unique weight to each head (110). When a user selects a head (110) with a specific weight and combines it with the body (120), the entire Egi (100) can exhibit performance predetermined by the weight of the head (110). Here, performance may include sinking speed and the angle of inclination underwater. For example, using a heavy head (110) increases the sinking speed, allowing for rapid targeting of deep water, while using a light head (110) increases the time the bait is exposed to the target fish species due to slow sinking. Additionally, depending on the center of gravity design of the head (110), the Egi (100) can be induced to sink in a horizontal position or at a specific angle of inclination, which enables various targeting patterns depending on the activity level of the target fish species.

[0063] FIG. 4a illustrates in detail, step by step, the initial assembly process of forming an internal connection structure by combining core components constituting an Egi (100) according to one embodiment.

[0064] In operation 410, the user can first insert the pin rod from the rear into a through hole formed in the center of the body. The pin rod moves along the interior of the body so that a connecting ring located at the front of the pin rod is positioned at the front opening of the body. At this stage, the pin is loosely seated inside the body, which may be a preparatory step to facilitate connection with the head in a subsequent step.

[0065] In operation 420, the user can pre-attach a connecting member, which is a small silicone band, to an internal connecting hook located inside the open rear part of the head. Since this small silicone band must be intentionally broken upon snagging, it may be a component designed to have a specific tensile strength that is weaker than the fishing line but capable of withstanding the resistance of the target fish species.

[0066] In operation 430, the user positions the head in alignment with the front end of the body and then pulls a small silicone band attached to the internal connecting link of the head to connect it to the front connecting link of the needle rod located at the front end of the body. Through this action, an internal connection between the head and the needle is completed. This connection is not visible from the outside and can be configured to operate only in specific situations, such as snagging, to detach the needle.

[0068] FIG. 4b illustrates in detail, step by step, the later process of completing the assembly by firmly binding the exterior of the Egi (100) after the internal connection is completed.

[0069] In operation 440, after the internal connection is completed, the user may use a connecting member, which is a large silicone band, to firmly secure the head and body from the outside. This connecting member may be designed to have much higher durability and elasticity than the internal connecting member. For assembly, the user may first secure one end of the large silicone band by hooking it onto a lower connecting hook protruding from the bottom of the body.

[0070] In Action 450, the user can pull the large silicone band fixed to the bottom of the body upward to wrap around the outside of the head and hook it onto the upper connecting ring located at the top of the head. The strong elastic tension of the silicone band generated during this process strongly compresses the rear of the head and the front of the body against each other, allowing the two parts to be firmly joined as if they were a single unit. This connection provides stability, preventing the head and body from separating even during strong casting or vigorous action while fishing.

[0071] The finished state (460) shows the final state of the jig (100) that has completed all assembly processes and can be used for fishing immediately. In this state, the jig (100) has a connecting structure internally for separating the fin when snagged, and a rigid joining structure externally for normal use. The user can easily replace the head or the worn fin by performing this assembly process in reverse.

[0073] According to one embodiment, the fishing hook (130) may be composed of a fishing hook rod penetrating the body (120) and a hook bundle coupled to the rear end of the fishing hook rod and including a plurality of fishing hooks. The fishing hook rod and the hook bundle may be coupled by a second connecting member having a lower breaking strength than the connecting member (140). The second connecting member may include a dial-type friction force adjustment device or a replaceable strength pin so that the user can adjust the breaking strength according to the frequency of snagging or the size of the target fish species. In the event of a relatively weak snag where only the tip of the fishing hook catches an obstacle, only the hook bundle is separated, and in the event of a relatively strong snag where the entire fishing hook rod catches an obstacle, the entire fishing hook (130) may be separated. Additionally, when the hook bundle is separated, a water-soluble dye pellet compressed inside is released to visually notify the user of the damage to the fishing rig, and a loss notification function may be further included.

[0074] According to one embodiment, the needle (130) may have a functionally subdivided structure. The needle (130) may be composed of a needle rod, which is a structure that determines the length and is connected to the head (110), and a hook bundle that is connected to the rear end of the needle rod and is responsible for actual capture and includes a plurality of fishing hooks. These two parts may have a structure that is not permanently connected and is separable.

[0075] The needle rod and the needle bundle can be joined through a second connecting member. This second connecting member may be designed to have a breaking strength intentionally lower than that of the connecting member (140) connecting the head (110) and the entire needle (130). For example, if the breaking strength of the connecting member (140) is 3 kgf, the second connecting member may be manufactured to break at 1.5 kgf, which is lower than that.

[0076] According to one embodiment, the second connecting member may include a function that allows the user to adjust its breaking strength. For example, a dial-type friction force adjustment device may be provided so that the user can finely adjust the force gripping the needle bundle by turning the dial. As another example, various types of replaceable pins with different strengths (e.g., a green pin that breaks at 1 kgf, a yellow pin that breaks at 1.5 kgf) may be provided so that the user can select and combine a pin suitable for the field conditions. The specific form of such adjustment device or the strength of the pin is merely an example and is not limited thereto, and may vary depending on the design of the product.

[0077] According to one embodiment, the Egi (100) can react differentially to the strength of the snag through a multi-stage breaking structure. In a relatively weak snag situation, such as when only the tip of the fishing hook is slightly caught in a rock crevice, only the second connecting member, which is the weakest connecting link, is broken, and only the hook bundle can be separated. This allows the rig to be retrieved with minimal loss of parts. On the other hand, in a relatively strong snag situation, such as when the entire pin rod is deeply caught in an obstacle, a stronger force is applied, causing the connecting member (140) to break and the entire pin (130) to be separated.

[0078] Additionally, the fishing rig (130) may include a loss notification function. Water-soluble, highly concentrated dye pellets may be compressed and embedded within the joint between the fishing rig rod and the hook bundle. When the hook bundle is separated due to a weak snag, these pellets are exposed to water and dissolve, leaving a visually identifiable trace of color (e.g., fluorescent green) underwater. This allows the user to immediately recognize that damage has occurred to their rig and prevents them from continuing to fish in vain. In addition to dye pellets, other forms of signaling substances such as bubble generators or fragrances may be used, and this is merely an example and is not limited to this.

[0080] According to one embodiment, the connection between the head (110) and the body (120) may include a quick-release locking structure that allows a user to quickly replace the head (110) without a tool. The quick-release locking structure may consist of an L-shaped guide groove formed at the rear end of the head (110) and a guide pin formed at the front end of the body (120), thereby enabling a bayonet connection method in which the head (110) and the body (120) are firmly integrated without play by pushing the head (110) into the body (120) and rotating it at a specific angle. The bayonet connection method may refer to a method of fast and safe connection and separation by inserting a grooved plug into a socket and then slightly rotating it to secure the groove to a latch. This structure prevents shaking of the connection part even when replacing the head (110), thereby maintaining the unique sinking speed and underwater tilt angle of each head (110) equally.

[0081] According to one embodiment, the head (110) and body (120) of the jig (100) can be joined through a quick-release locking structure to maximize user convenience and performance stability of the rig.

[0082] The quick-release locking structure may refer to a fastening method designed to allow the user to quickly replace the head (110) with bare hands without the need for separate tools. This may be intended to increase the efficiency of fishing by enabling immediate changes in the rig to match the constantly changing field conditions.

[0083] The quick-release locking structure may have a bayonet fastening method. This method may consist of one or more L-shaped guide grooves formed on the inner surface of the rear end of the head (110) and a corresponding number of guide pins protruding from the outer surface of the front end of the body (120). The user can join the two parts with a simple action of aligning the guide pins with the guide grooves, pushing the head (110) into the body (120), and then rotating it at a specific angle (e.g., 90 degrees). A groove or protrusion is formed at the end of the L-shaped groove to hold the pins, thereby maintaining a locked state so that once joined, they cannot be easily separated. This type of fastening method is merely an example and is not limited thereto; other forms of quick-release structures, such as a cam-lock method, may also be applied.

[0084] This structure can have the effect of fundamentally preventing shaking, or play, in the joint whenever the head (110) is replaced. Robust integration may be an essential condition for stably realizing the unique performance of each head (110). If play occurs in the joint, shaking or twisting may occur when the Egi (100) is subjected to water resistance, and the unique sinking speed and underwater tilt angle designed by the manufacturer may not be properly realized. A robust locking structure, such as a bayonet, can ensure that the performance intended by the user is consistently reproduced every time by fixing the head (110) in the same position and posture regardless of which head (110) is connected.

[0086] According to one embodiment, the fishing rod (130) may have a structure in which an inner and outer rod are combined, and a spring-loaded locking device is built in which the length can be adjusted only when the user presses a button and automatically locks in the current position when the button is released, so that the set length does not change even during vigorous fishing movements. The front part of the fishing rod (130) is equipped with a gear-ratchet based angle adjustment device that allows the angle to be adjusted by turning a dial without replacing separate parts, so that the angle of the fishing rod (130) can be precisely set to match the underwater posture of the head (110) selected by the user. The interior of the fishing rod is formed as an empty space so that the user can fill it with a solid or gel-type attractant material, and a fine discharge port is formed near the hook bundle so that a concentrated scent is released only around the hook, thereby inducing the target fish species to inhale to the hook without foreign matter.

[0087] According to one embodiment, the rod (130) may have a structure in which an inner and outer rod are joined to each other in a sliding manner. A spring-loaded locking device may be built into this structure. For example, a plurality of locking grooves may be formed at regular intervals on the inner rod, and a spring-loaded pin connected to a button that a user can press may be provided on the outer rod. When the user presses the button, the pin retracts to unlock, and in this state, the length of the rod can be freely adjusted. When the hand is released from the button, the pin advances again and is inserted into the nearest locking groove, so that the current length can be automatically fixed. Such a locking device can provide stability so that the length set by the user does not change even during vigorous fishing actions such as casting or retrieving the rig.

[0088] According to one embodiment, an angle adjustment device may be provided at the front portion of the fishing hook (130), that is, the portion connected to the head (110). This device may include a gear-ratchet based mechanism that can adjust the connection angle of the fishing hook (130) by simply turning a dial without replacing separate parts. The user can tilt the fishing hook (130) up or down by a set angle (e.g., 5 degrees, 10 degrees) by turning the dial. This function may be intended to precisely set the final position of the fishing hook to match the unique underwater posture of the head (110) selected by the user. For example, when using a head (110) that is upright on the bottom, it may be possible to operate by slightly raising the angle of the fishing hook (130) to prevent snagging. The range or method of the adjustable angle is merely an example and is not limited thereto, and may vary depending on the design of the product.

[0089] According to one embodiment, the interior of the jigs may be formed as an empty space and utilized as a storage area for storing a lure. The user may detach the rear end (e.g., a bundle of needles) of the jigs (130) and fill the interior with a solid or gel-type lure. One or more fine discharge holes may be formed near the bundle of needles of the jigs. Through these discharge holes, the lure inside gradually dissolves in the water, releasing a scent concentrated only around the fishing hook. This can have the effect of not only luring the target fish species to the entire jig (100) but also accurately guiding them to the hook, which is the final point of attack, thereby ensuring a reliable bite without any foreign sensation. The form or composition of the lure is merely an example and is not limited thereto, and can be selected in various ways depending on the target fish species or the environment of use.

[0090] According to one embodiment, the body (120) of the Egi (100) may include additional functions to maximize the attraction effect for target fish species. For example, an empty receiving space may be formed inside the body (120). The user may fill this space with a gel or solid-form attractant. The attractant is slowly released underwater through a fine discharge opening formed on the surface of the body (120), thereby effectively attracting target fish species sensitive to smell. Additionally, an insertion hole penetrating the body (120) may be formed, and the user may insert a disposable light-emitting element, such as a chemical light, into this insertion hole to add a visual attraction effect. The type of such attractant or the specifications of the light-emitting element are merely examples and are not limited thereto, and may be varied depending on the fish species to be caught or the usage environment.

[0091] According to one embodiment, the body (120) of the Egi (100) may be divided into two or more parts to enable more natural and lively movement, and may have a joint structure in which these parts are connected by a hinge. For example, the body (120) may be composed of a first body that is coupled to the head (110) and a second body through which the needle (130) passes. By connecting the first body and the second body with a hinge, the body (120) can produce a movement that resembles a small, living fish wagging its tail due to water resistance when the angler operates the rig.

[0092] According to one embodiment, the Egi (100) may further include a structure to suppress the occurrence of snagging itself. A plurality of flexible hidden guides extending rearward may be provided around the rear end of the body (120). These hidden guides may be arranged to surround the fishing hook of the shovel (130). The hidden guides prevent the fishing hook from directly touching light obstacles such as seaweed or branches, thereby preventing unnecessary snagging. On the other hand, when a target fish attacks the shovel (130), the hidden guides made of a flexible material can easily bend or be pressed, allowing the fishing hook to be firmly embedded in the target fish. The material and number of these hidden guides are merely examples and are not limited thereto, and can be set in various ways considering the balance or protective performance of the rig.

[0093] According to one embodiment, the Egi (100) may further include a structure to suppress the occurrence of snagging itself. A plurality of extension members extending rearward may be further provided around the rear end of the body (120). The extension members may be arranged in a manner that surrounds the fishing hook of the shovel (130). The extension members can serve to prevent unnecessary snagging by preventing the fishing hook from directly contacting light obstacles such as seaweed or branches. On the other hand, when a target fish species attacks the shovel (130), the extension members made of a flexible material can easily bend or be pressed, allowing the fishing hook to be firmly embedded in the target fish species. The material and number of such extension members are merely examples and are not limited thereto, and can be set in various ways considering the balance or protective performance of the rig.

[0094] According to one embodiment, the Egi (100) may have a structure that generates a unique sound effect through the interaction of each module. Fine irregularities or ratchet structures may be formed on the rear coupling surface of the head (110) and the front coupling surface of the body (120). When an angler applies action to the Egi (100), fine movement occurs between the head (110) and the body (120), and these irregular structures may rub against or collide with each other to produce sound or vibration of a specific frequency. By replacing and combining the head (110) or body (120) with different materials or shapes of irregularities, the type or volume of the sound produced by the Egi (100) can be changed. This can provide an auditory attraction effect that stimulates the curiosity of target fish species. The form of such sound-generating structure is merely an example and is not limited thereto, and can be implemented in various ways.

[0095] According to one embodiment, the fishing buoy (130) that is separated by snagging can be designed to perform additional functions even after it is lost. For example, the inner rod of the fishing buoy (130) can be made of a buoyant material with a specific gravity lighter than water, or an air layer can be formed inside. In this case, the fishing buoy (130) separated by snagging will gradually rise to the surface of the water. This can serve as a marker buoy that informs the user of the exact location of underwater obstacles, thereby helping to prevent repeated loss of the rig at the same point. As another example, a water-soluble block containing a highly concentrated attractant can be embedded inside the fishing buoy (130). When the separated fishing buoy (130) remains on the bottom, this block can gradually dissolve and exert an attracting effect at that point, thereby gathering other target fish species in the surrounding area.

[0096] According to one embodiment, the modularity of the Egi (100) can be extended to the material of the parts. The body (120) may consist of a rigid inner frame and an outer skin that the user can replace and attach to the frame. The user can combine a hard skin made of hard plastic material with the same inner frame to produce fast and strong movements on the Egi, or combine a soft skin made of soft silicone material to produce natural waves and flexible movements. Additionally, by using a skin made of a material having a specific gravity, the buoyancy of the entire Egi (100) can be controlled, and a state can be achieved where it neither sinks nor rises in the water.

[0097] The embodiments described above may be implemented as hardware components, software components, and / or combinations of hardware and software components. Although the embodiments have been described above with reference to the limited drawings, those skilled in the art can apply various technical modifications and variations based on the above. For example, appropriate results may be achieved even if the described techniques are performed in a different order than described, and / or the components of the described system, structure, device, circuit, etc. are combined or assembled in a form different from the described method, or are replaced or substituted by other components or equivalents.
