[0001] The present invention mainly relates to a device for a hollow soft lure suitable for large pelagic fish trolling fishing. Keni It relates to.

Background Art

[0002] The applicant of the present invention has commercialized an octopus-shaped soft lure described in Patent Document 1 and a fish-shaped lure described in Patent Document 2, both of which are provided with a hollow lure body (lure body) (10) formed from a flexible thermoplastic resin.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, since the lures disclosed in the above-mentioned Patent Documents 1 and 2 are all soft lures having a hollow lure body (10) molded from a flexible thermoplastic resin, when the fishing hooks (30) and (36) are attached to the lure body (10) from the rear as described above, and the soft lure is submerged in the sea and pulled from the front for trolling fishing, the lure body (10) is subjected to strong resistance from the waves, compressing and deforming to shorten its overall length, and it fails to impress the target fish such as tuna, mahi-mahi, yellowtail, and bonito with the realistic swimming movement of live bait (squid or fish), resulting in a problem in attracting and catching fish.

[0007] In that case, not only the nylon fishing line (41) directly connected to the former fishing hook (30), but also the strong polyethylene fiber cord (preferably the product name "Dyneema") (40) connecting the latter fishing hook (36) and fishing line (37) are flexible and can be freely deformed. Therefore, even when subjected to the compressive deformation force on the lure body (10) due to the resistance of the waves, there is no bracing strength (rigidity) to counteract it, and as a result, the occurrence of the above problem cannot be prevented. [Means for solving the problem]

[0008] The present invention aims to solve these problems, and in order to achieve this objective, claim 1 describes a hollow soft lure rig in which a fishing line is passed from the rear into the hollow interior of the lure body and then routed forward from a fishing line insertion hole at the front end of the lure body in order to pull the fishing hook, which is locked into the fishing hook locking portion of the fishing hook attachment part at the rear end of the lure body, from the front,

[0009] A connecting ring, formed by riveting to the folded rear end of the fishing line, and a mounting ring, bent and formed on the front end of the fishing hook, are connected by a metal snap, one end of which is detachable from the mounting ring.

[0010] The weight, which is interposed between the crimping rivet for the connecting ring and the front end of the lure body, is slidably passed through the fishing line.

[0011] The effective length of the connection from the weight to the fishing hook, via the rivet and snap used to fasten the connecting ring of the fishing line, is set to be substantially equivalent in length to the physical length from the front end of the lure body to the hook locking point of the fishing hook attachment part at the rear end.

[0012] The lure body, which is pulled from the front during use, is characterized by a design that prevents it from being abnormally deformed and shortened in overall length even when subjected to compressive force from wave resistance from the front, due to a bracing action that counteracts that compressive force.

[0013] Claim 2 describes a fishing hook that is substantially anchor-shaped and made of a single metal wire, comprising a substantially Ω-shaped mounting ring bent and formed in the middle of the metal wire having a certain length, symmetrical arc-shaped hooks (points) bent and formed at both ends of the metal wire, and a straight shank that branches from the mounting ring and runs in a parallel line to both hooks.

[0014] A reddish-colored string is coiled and integrated into the shank,

[0015] The above mounting ring is connected to one end of the metal snap in a perpendicular relationship,

[0016] The above-mentioned hooks are characterized by being able to be detachably locked into a pair of corresponding hook-locking grooves on a hook attachment portion provided at the rear end of the lure body.

[0017] Claim 3 describes the snap as being in an overall elongated ring shape, made of a hard steel wire, piano wire, or other metal wire thinner than a fishhook, of a certain length.

[0018] The above metal wire is provided with a roughly Ω-shaped fishing line connecting end formed in the middle of the metal wire in order to connect the middle of the metal wire to a fishing line connecting ring, a roughly J-shaped first hook formed in the middle of the metal wire that extends from the fishing line connecting end at one of the cut ends of the metal wire, and a second hook formed in the opposite direction to the first hook that extends from the fishing line connecting end at the other cut end of the metal wire,

[0019] The first hook and the second hook are arranged as connecting ends for a fishing hook of the same size and curved shape that overlap each other. These connecting ends for the fishing hook are forcibly spread apart from the overlapping state of the first and second hooks and attached to the fishing hook mounting ring in a way that allows them to be easily inserted and removed, thereby maintaining a connection between the mounting ring and the snap in an orthogonal relationship.

[0020] Claim 4 is characterized in that the diameter of the approximately J-shaped bend of the first and second hooks at the hook-connecting end of the snap is made larger than the diameter of the approximately Ω-shaped bend at the hook-connecting end.

[0021] Claim 5 is characterized in that the entire surface of the metal wire forming the snap is coated with a corrosion-resistant red-colored resin coating. [Effect of the Invention]

[0022] According to the above configuration of claim 1, there is an effect that can reliably solve the problems of the prior art described at the beginning.

[0023] In other words, for a length of practically the same length as the physical length from the front end of the hollow lure body to the hook attachment point at the rear end where the hook is secured, the fishing line is tensioned and straightened to pull the hook from the front. Along this line, a weight, a rivet for crimping the connecting ring, a metal snap, and the hook are connected in series from front to back. These components together form a rigid structure extending in the front-to-back direction along the longitudinal centerline of the lure body. Even when the lure body is subjected to compressive force from the wave resistance from the front, this structure acts as a counteracting force, preventing deformation. As a result, it prevents abnormal deformation of the hollow soft lure (which affects the original swimming movement and appearance of live bait) that occurs when it is pulled while submerged in the sea, thus achieving excellent results in attracting and catching tuna, mahi-mahi, yellowtail, and other target fish.

[0024] In that case, if the configuration of claim 2 is adopted, the fishing hook of the hollow soft lure rig can be formed into a high-strength, nearly anchor-shaped structure from a single metal wire, eliminating the need for welding or brazing like with treble hooks, and also providing mass production benefits. In particular, by securing the pair of symmetrical hooks to a corresponding pair of hook-locking grooves at the hook attachment point on the lure body, it can be applied to a squid-shaped hollow soft lure with a transparent or translucent lure body, allowing the lure to swim realistically like a real squid, and the reddish color of the string wrapped around and integrated with the shank can also impress the target fish with the internal organs of a squid, stimulating their feeding instincts.

[0025] Furthermore, if the configuration of claim 3 is adopted, the snap's connecting end for a fishing hook, which is formed into an overall elongated ring shape from a single hard steel wire, piano wire, or other metal wire, can be detachably attached to the fishing hook's mounting ring. The overlapping state of the first and second hooks provides a stable and durable connection that prevents accidental detachment.

[0026] In that case, by using a flat tool such as a flathead screwdriver or a coin, or, as long as it is handled safely, directly inserting the hook attachment ring of the snap into the gap between the first and second hooks that form the hook attachment end of the snap, and forcibly pushing it open, the hook attachment end of the snap can be instantaneously and automatically maintained in a connection state perpendicular to the hook attachment ring, which is extremely convenient.

[0027] If the configuration of claim 4 is adopted, the fishing line connecting end of the snap, which is bent to a relatively small diameter, can be used to fold the rear end of a fishing line made of nylon thread back to form a connecting ring and secure it with a rivet, while the fishing hook connecting end is bent to a relatively large diameter, so it can be easily connected to the attachment ring of a fishing hook made of a metal wire thicker than the snap, and even if the snap is made of a metal wire thinner than the fishing hook, the first and second hooks of the fishing hook connecting end remain in an overlapping state, so, combined with the restoring force of the forced opening described above, there is no risk of a decrease in connection strength or detachment of the connection.

[0028] Furthermore, if the configuration of claim 5 is adopted, the reddish color of the corrosion-resistant resin coating applied to the metal wire of the snap can impress the target fish with the internal organs of a squid, stimulating their feeding instinct. Therefore, it is extremely beneficial as a rig to be applied to a hollow soft lure in the shape of a squid, which has a transparent or translucent lure body. [Brief Description of the Drawings]

[Figure 14] This is a diagram showing the use of a hollow soft lure while it is being submerged in the water and retrieved. [Figure 15] This is a bottom view showing an example of use in a different mechanism corresponding to Figure 7. [Figure 16] This is a cross-sectional view taken along line 16-16 in Figure 15. [Modes for carrying out the invention]

[0030] Preferred embodiments of the present invention will be described in detail below with reference to the drawings. Figures 1 to 9 show an embodiment applied to a squid-shaped hollow soft lure (A), where (10) is a hollow lure body made of a flexible transparent or translucent thermoplastic resin (preferably acrylic resin) or thermoplastic elastomer, and has an overall substantially circular cross-section from a bullet-shaped body (11) through a cylindrical head (12) with a smaller diameter than the base end of the body (11) to a cylindrical hook attachment part (13) with an even smaller diameter than the head (12).

[0031] In this case, a pair of left and right eye covering surfaces (14) protrude from the head (12) of the lure body (10) in a lateral arc shape. (15) are eyes painted in a dark color such as black on the concave curved surface on the back of the eye covering surface (14), and (16) is a foot locking flange that protrudes slightly larger in diameter than the head (12) from the boundary (step) between the head (12) of the lure body (10) and the hook attachment part (13), and the base end of the windsock-shaped foot (17), which will be described later, will be locked here.

[0032] In the lure body (10) described above, a certain length of the body (11) is formed with a pair of left and right side edging flanges (18) that protrude horizontally in the lateral direction. These protruding side edging flanges (18) resist the wobbling motion of the hollow soft lure (A) that attempts to rotate around the fishing line described later, and give the impression of the horizontal, stable swimming posture of a live bait squid. In addition, the area near the tip (front end) of the bullet-shaped body (11) on both sides of the side edging flanges (18) may also be formed as a pair of left and right partial fins (ears) (not shown) that protrude horizontally in the lateral direction.

[0033] Furthermore, a fishing line insertion hole (19) is formed at the tip (front end) of the body (11) of the lure body (10), communicating with the hollow interior of the lure body (10). This fishing line insertion hole (19) is located at the center of the lure body (10), which has a nearly circular cross-section, and the fishing line described later is threaded and routed along the longitudinal centerline of the lure body (10).

[0034] On the other hand, at the tip (rear end) of the hook attachment portion (13) of the lure body (10), a pair of hook-locking grooves (20) are cut out in a U-shape that opens backward in a side view, as shown in Figures 3, 6, and 9. It is preferable that the bottom surfaces (front end surfaces) of both hook-locking grooves (20) be shaped like a V-shape that widens backward in a flat / bottom view, as shown in Figures 2 and 8, so that their inclined surfaces can stably receive the bent middle portion of the anchor-shaped hook (F) described later.

[0035] Furthermore, the fishing hook attachment portion (13) of the lure body (10) also has a pair of circular fishing hook insertion holes (21) formed through it, which can be used interchangeably with the pair of left and right fishing hook locking grooves (20).

[0036] The aforementioned windsock-shaped foot portion (17) is molded separately from the lure body (10) from the same flexible transparent or translucent thermoplastic resin or thermoplastic elastomer as the lure body (10), and is equipped with numerous windsock strips (22). The slits (grooves) (23) for forming the windsock strips (22) may be cut by machining after molding, rather than by using a molding die.

[0037] Furthermore, a positioning step (24) with a nearly triangular cross-section is provided at the boundary between the base end of the foot portion (17) and the windsock strip (22). This positioning step (24) is locked to the foot portion locking flange (16) of the lure body (10), and the foot portion (17) and the lure body (10) are bonded together with a colorless (transparent) adhesive, forming an overall circular concentric communication opening.

[0038] As is clear from Figures 1-9, in the state in which the feet (17) of the hollow soft lure (A) are attached to the lure body (10), the cylindrical hook attachment portion (13) of the lure body (10) is covered from the outside by the streamer-like strip (22) of the feet (17), and the hook (F) that is inserted into and locked in the hook locking groove (20) or hook insertion hole (21) of the hook attachment portion (13) is camouflaged so that it is not easily visible from the outside.

[0039] In the illustrated embodiment, the manufacturing method for the squid-shaped hollow soft lure (A) involves assembling the lure body (10) from a pair of body half-segments (a dorsal half and a ventral half of the body) (10a) (10b) with symmetrical contour shapes and a nearly semicircular cross-section by bonding the left and right side edging flanges (18) together in a girdle-like manner using a colorless (transparent) adhesive, thereby creating a hollow product with a nearly circular cross-section.

[0040] Moreover, in this case, the concave curved surfaces on the back of both main body half-segments (10a) and (10b) are pre-attached to the body transfer sheets (25a) and (25b) respectively, which are color printed on hologram sheets (not shown) in a tone that gives the impression of the body surface (skin) of live bait (squid), and the head transfer sheets (26a) and (26b) are also pre-attached, respectively, and these can be seen through from the outside.

[0041] Furthermore, the windsock-shaped foot portion (17) is also bonded together from a pair of symmetrical foot half-segments (dorsal and ventral halves of the foot) (17a) (17b) via a colorless (transparent) adhesive. In this case as well, the concave curved surfaces on the underside of both foot half-segments (17a) (17b) are pre-attached to the respective foot transfer sheets (27a) (27b), which are hologram sheets (not shown) with color printing in tones that give the impression of the body surface (skin) of live bait (squid).

[0042] Furthermore, the upper foot half-segment (17a) of the foot (17) is attached to the head (12) of the upper body half-segment (10a) of the lure body (10) from above with a colorless (transparent) adhesive, creating a covering and integrated structure, while the lower foot half-segment (17b) is attached to the head (12) of the lower body half-segment (10b) from below with a colorless (transparent) adhesive, creating a covering and integrated structure. Thus, the foot (17) as a whole maintains a concentric, communicating opening with the hollow lure body (10).

[0043] The manufacturing method for the squid-shaped hollow soft lure (A) is not limited to the above method; other manufacturing methods can be freely adopted. In short, any soft lure (A) that has a hollow lure body (10) extending from the body (11) through the head (12) to the hook attachment part (13) and legs (17) is acceptable.

[0044] Next, Figures 7-9 show the mechanism for the hollow soft lure (A) described above. In order to pull the fishing hook (F), which is locked in the fishing hook locking groove (fishing hook locking location) (20) of the fishing hook attachment part (13) at the rear end of the lure body (10), from the front, a fishing line (28) is passed from the rear into the hollow interior of the lure body (10) and then routed forward through a fishing line insertion hole (19) that opens in the body (11) of the lure body (10). The soft lure (A) is then pulled from the front and towed using this fishing line (28).

[0045] Specifically, the fishing line (28) is made of nylon thread, and as is clear from Figures 8 and 9, the tip (rear end) located inside the hollow body of the lure (10) is folded over and fixed in place by a rivet (30) as a connecting ring (29). Furthermore, a cover tube (not shown) is attached to the folded rear end of the connecting ring (29) to protect the fishing line (28) from friction with the metal snap (S) and from tensile loads.

[0046] (31) is a weight interposed between the front end of the bullet-shaped body (11) of the lure body (10) and the crimping rivet (30) of the connecting ring (29). It is made of lead or other heavy material and prevents the soft lure (A) from floating up from the surface of the sea, keeping it submerged. The size (weight) and shape of the weight (31) can be selected appropriately, but it is preferable to make it bullet-shaped or conical, for example, to also provide a shape-retaining function for the front end of the lure body (10).

[0047] Furthermore, the fishing hook (F) described above is made of a single hard steel wire or other metal wire and has an overall anchor shape as shown in Figure 10. The middle section of the metal wire, which has a certain length, is bent to form an Ω-shaped mounting ring (32), and the cut ends of the metal wire are formed as a pair of symmetrical hooks (points) (33) that protrude laterally in a nearly horizontal arc shape.

[0048] Furthermore, the section branching off from the mounting ring (32) and connecting to the pair of hooks (33) on the left and right is arranged in parallel as a straight shank (34). It is desirable to coil and integrate a strong cord (35) colored with a reddish hue around this parallel shank (34). This prevents the shank (34) from opening improperly, and because the cord (35) is visible from the outside of the lure body (10), the reddish hue can give target fish such as tuna and mahi-mahi the impression of the internal organs of live bait (squid), thus stimulating their feeding instincts.

[0049] The mounting ring (32) at the base end (front end) of the anchor-shaped fishing hook (F) is connected to one end (rear end) of the metal snap (S) in a perpendicular relationship, while both hooks (points) (33) of the fishing hook (F) are locked and detachably from the rear into a pair of fishing hook locking grooves (20) which are corresponding fishing hook locking points on the fishing hook mounting part (13) provided at the rear end of the lure body (10).

[0050] To elaborate on the above-mentioned metal snap (S), it consists of a metal wire thinner than a standard fishing hook (F), such as a hard steel wire or piano wire of a certain length. As is clear from Figures 11-13, the middle of the metal wire is bent into an approximately Ω shape to serve as a connecting end (36) for the fishing line, which connects to the connecting ring (29) of the fishing line (28).

[0051] Furthermore, one end of the metal wire is cut off and bent into a roughly J-shape, extending from the fishing line connecting end (36) as the first hook (37a), while the other end of the metal wire is cut off and bent into a roughly J-shape, also extending from the fishing line connecting end (36) but in the opposite direction (symmetrical) to the first hook (37a). Moreover, the first and second hooks (37a) and (37b) are formed as fishing hook connecting end (37) of the same size and bend shape (J-shape) that overlap each other.

[0052] The snap (S) for the rig described above has an overall elongated ring shape as shown in Figures 9 and 11, with both ends in its longitudinal direction (front-to-back direction) forming a connecting end for the fishing line (36) and a connecting end for the fishing hook (37). The entire surface of the metal wire is coated with a reddish colored resin. (38) is the coating film, which is also colored red to give the impression of the internal organs of live bait (squid) to the target fish.

[0053] In this case, the diameter (D) of the approximately J-shaped bend of the first and second hooks (37a) and (37b) at the connecting end for the fishing hook (37) is dimensionally larger than the diameter (d) of the approximately Ω-shaped bend at the connecting end for the fishing line (36), allowing the fishing hook (F), which is made of a metal wire thicker than the snap (S), to be easily and stably connected to the mounting ring (32).

[0054] Furthermore, the connecting end (37) of the snap (S) for the fishing hook is positioned to overlap with the first and second hooks (37a) (37b) of the fishing hook (F), which are made of thinner metal wire than the fishing hook (F), allowing it to be detachably attached to and connected to the mounting ring (32) of the fishing hook (F).

[0055] In other words, by inserting a flathead screwdriver or other flat tool (not shown) into the gap between the overlapping first and second hooks (37a) and (37b) of the fishing hook connecting end (37), the first and second hooks (37a) and (37b) can be forcibly pushed apart (push open), and then attached to or removed from the mounting ring (32) of the fishing hook (F) in the same way that the fishing hook (F) is attached to or removed from the mounting ring (32). As long as it is handled safely, it is also possible to directly attach and detach the two without using the above-mentioned appropriate tool.

[0056] Since the attachment ring (32) of the fishing hook (F) and the first and second hooks (37a) (37b) that form the connecting end (37) of the snap (S) for the fishing hook are both formed by bending metal wire, when one is inserted into the other for attachment, both (the fishing hook and the snap) automatically rotate 90 degrees relative to each other and instantly become orthogonal in a connected state. Combined with the restoring force of the forced opening described above, there is no risk of the connected state accidentally coming apart.

[0057] Figures 7-9 show the entire rig used for the hollow soft lure (A) described above. As is clear from these drawings, the tip (rear end) of the fishing line (28) has a roughly Ω-shaped fishing line connecting end (36) which forms one end (front end) of a snap (S). This is connected to a connecting ring (29) formed by crimping and fixing the folded state of the fishing line (28) with a rivet (30), in a perpendicular relationship. A weight (31) that prevents the soft lure (A) from floating up from the surface of the sea is slidably threaded through the fishing line (28) just before the rivet (30). The weight (31) is interposed between the front end of the lure body (10) and the rivet (30), sandwiched between them.

[0058] On the other hand, a roughly Ω-shaped attachment ring (32) formed by bending the front end of an anchor-shaped fishing hook (F) is attached to the other end (rear end) of the snap (S) (37) by a forced pushing operation of the first and second hooks (37a) (37b) at the attachment end (37) for the fishing hook, and the middle of the bend of the symmetrical hooks (hook tips) (33) of the fishing hook (F) is detachably locked from the rear to a fishing hook locking groove (20) of a fishing hook attachment part (13) formed to correspond to the rear end of the lure body (10).

[0059] In addition to the weight (31) mentioned above, the fishing line (28), to which the fishing hook (F) is attached via a snap (S) to the connecting ring (29), is passed through the hollow interior from the rear of the lure body (10), and routed out from the fishing line insertion hole (19) of the lure body (10) to the front, where it is towed and used by a trolling fishing boat or cruiser (pleasure boat), but as shown in Figures 8 and 9, the fishing hook (F) is attached to the fishing hook locking part (13) of the fishing hook attachment part (13) of the lure body (10) When the fishing hook is locked into the fishing hook locking groove (20), the effective connecting length (e.g., 170 mm or 175 mm) (L1) in series from the weight (31) built into the hollow lure body (10) through the rivet (30) and snap (S) for fastening the connecting ring of the fishing line (28) to the fishing hook (F) is set to be substantially equivalent in dimension to the physical constant length (L2) from the front end of the lure body (10) to the fishing hook locking groove (20) of the fishing hook attachment part (13) at the rear end.

[0060] Furthermore, among the various members connected in series over the aforementioned functional connection length (L1), there are no strings or other flexible materials that can be freely bent and deformed, nor are there any rubber, sponge, or other stretchable materials whose length changes; all the necessary members are rigid metal products.

[0061] In other words, when the hollow soft lure (A) is used for trolling, and is pulled from the front in a state where it is submerged to an appropriate depth (Y) from the sea surface (ZZ) as shown in Figure 14 by the fishing line (28) to which the hook (F) is attached, even if the lure body (10) is subjected to a strong compressive force from the front due to wave resistance, the metal products (weights, rivets, snaps, and hooks) which are connected in series and packed virtually without gaps along the wiring of the fishing line (28) inside the hollow interior of the lure body (10) act as rigid muscles extending along the longitudinal centerline of the lure body (10), performing a counteracting action from inside the hollow interior to prevent the lure body (10) from being compressed and deformed.

[0062] When a target fish such as a tuna or mahi-mahi bites the lure body (10) of the soft lure (A), the fishing hook (F), subjected to the pulling force, is pulled away from the lure body (10) in a manner similar to the slackening of the rig on the fishing line (28), resulting in a so-called hook-dropping state.

[0063] As a result, the hollow soft lure (A) can be prevented from deforming improperly, and during trolling, it will always impress upon tuna, mahi-mahi, yellowtail, and other target fish the realistic swimming movement and appearance of live bait (squid or fish), resulting in excellent fish-attracting and catching results. Furthermore, the structure requires only the minimum necessary number of parts and is simple, so the benefits of mass production can be expected to be maximized.

[0064] Furthermore, in the hollow soft lure rig described based on Figures 7-9, the hook locking points of the hook attachment portion (13) at the rear end of the lure body (10) are a pair of left and right hook locking grooves (20), and the angler-shaped hook (F) is inserted into the grooves (20) that open backward from the rear, with the bent ends of both hooks (points) (33) inserted into the grooves (20). However, as shown in another example of use in Figures 15 and 16, the hook locking points of the hook attachment portion (13) may also be a pair of upper and lower hook insertion holes (21), and a hook (F) with one hook (point) (33) bent in an arc shape may be inserted into the preferably lower hook insertion hole (21) from below, and secured into the rig.

[0065] The other components of the rigs in Figures 15 and 16 are substantially the same as those in Figures 7 to 9. In all of these rigs, the flanges (18) on both sides that extend from the hollow lure body (10) are useful for allowing the live bait, such as squid, to swim in a stable horizontal position, and are also effective in exerting a bracing force to counteract the compressive deformation of the lure body (10).

[0066] Although an embodiment of the present invention applied to a squid-shaped hollow soft lure (A) has been described, the present invention can be applied not only to the squid-shaped soft lure (A) but also to the fish-shaped one described in Patent Document 2 at the beginning, as long as it is a soft lure (A) equipped with a hollow lure body (10). In the fish-shaped hollow soft lure of Patent Document 2, although the half segments (10L) and (10R) of the lure body (lure body) (10) are joined together on the front side of the imaginary line (Z-Z), they are open on the rear side. Therefore, it can be said that a mechanism can be formed in which the notch on the imaginary line (ZZ) is used as a hook-locking point, and the hook (36) is locked in place from the rear during its bend, as shown in Figures 28 and 43.

Claims

1. In this hollow soft lure rig, a fishing line is threaded through the hollow interior of the lure body from the rear and then routed forward through a fishing line insertion hole at the front of the lure body in order to pull the fishing hook, which is secured to the fishing hook locking point at the rear end of the lure body, from the front. A connecting ring, formed by riveting to the folded rear end of the fishing line, and a mounting ring, bent and formed on the front end of the fishing hook, are connected by a metal snap, one end of which is detachable from the mounting ring. The weight, which is interposed between the crimping rivet for the connecting ring and the front end of the lure body, is slidably passed through the fishing line. The effective length of the connection from the weight to the fishing hook, via the rivet and snap used to fasten the connecting ring of the fishing line, is set to be substantially equivalent in length to the physical length from the front end of the lure body to the hook locking point of the fishing hook attachment part at the rear end. A hollow soft lure rig characterized by a design that prevents the lure body, which is pulled from the front and subjected to compressive force from wave resistance from the front, from being shortened or deformed abnormally by a bracing action that counteracts that compressive force.

2. The fishing hook is roughly anchor-shaped, consisting of a single metal wire, and comprises a roughly Ω-shaped mounting ring formed by bending the middle of the metal wire, which has a certain length, symmetrical arc-shaped hooks formed by bending the ends of the metal wire, and a straight shank that branches off from the mounting ring and runs in parallel to both hooks. A reddish-colored string is coiled and integrated into the shank, The hollow soft lure rig according to claim 1, characterized in that the mounting ring is connected to one end of a metal snap in a perpendicular relationship, while the two hooks are detachably locked into a corresponding pair of fishing hook locking grooves on a fishing hook mounting portion provided at the rear end of the lure body.

3. A snap for use in a hollow soft lure rig according to claim 1, comprising a hard steel wire, piano wire, or other metal wire thinner than a fishing hook, of a certain length. The middle of the metal wire is bent into an approximately Ω shape to serve as a connecting end for the fishing line, which connects to the connecting ring of the fishing line. One end of the above-mentioned metal wire is cut and used as the first hook, and is bent into a roughly J-shape extending from the connecting end for the fishing line, The other end of the above-mentioned metal wire is cut off and used as a second hook, and is bent into an approximately J-shape in the opposite direction to the first hook which extends from the connecting end for the fishing line. Furthermore, the snap for hollow soft lure rigs is characterized in that the first hook and the second hook are configured as connecting ends for fishing hooks of the same size and curved shape that overlap each other, and these connecting ends for fishing hooks can be detachably attached to the attachment ring of a fishing hook.

4. The snap for a hollow soft lure rig according to claim 3, characterized in that the connecting end for the fishing hook is forcibly spread apart from the overlapping state of its first and second hooks, and can be attached to or detached from the attachment ring of the fishing hook by inserting or removing it from the attachment ring, thereby creating a relationship perpendicular to the attachment ring.

5. The snap for a hollow soft lure rig according to claim 3 or 4, characterized in that the diameter of the approximately J-shaped bend of the first and second hooks at the connecting end for the fishing hook is made larger than the diameter of the approximately Ω-shaped bend at the connecting end for the fishing line.

6. The hollow soft lure rig snap according to claim 3, characterized in that the surface of the metal wire is coated with a corrosion-resistant red-colored resin.
