Abstract
Description
Technical Field
[0001] This invention relates to the field of fishing technology, and in particular to an elastic stretch biomimetic swing hook assembly. Background Technology
[0002] The drawback of the hook rigs currently used by fishing enthusiasts is that when anglers choose to fish at a fixed location, the bait in the hook rig cannot move, meaning that the bait in the hook rig is essentially dead bait, and its attractiveness to target fish is far less than that of live bait that can move. Summary of the Invention
[0003] The purpose of this invention is to provide an elastic stretch bionic swing hook assembly, characterized by comprising a main line, an elastic stretch frame, a leader line, a fish hook, a sinker connecting line, and a sinker. The main line passes through the main line guide hole at the upper end of the elastic stretch frame and connects to the elastic arm traction point. One end of the leader line is connected to the elastic arm leader line connection point, and the other end is connected to the fish hook. One end of the sinker connecting line is connected to the sinker connecting line fixing point of the elastic stretch frame, and the other end is connected to the sinker. When the main line is under force, the main line passes through the main line guide hole of the elastic stretch frame and applies the tension to the elastic arm traction point. Utilizing the elasticity of the elastic arm's memory elastic component, the elastic arm is pulled to swing. The elastic arm, through the leader line at its end, pulls the fish hook to swing, causing the bait on the fish hook to move back and forth.
[0004] The main line is the fishing line that the angler selects based on the size of the target fish.
[0005] The elastic stretching exercise frame consists of a main line guide hole bracket, a sinker connecting line bracket, and an elastic arm. The main line guide hole bracket and sinker connecting line bracket are composed of a bracket body, a main line guide hole, an elastic arm connection point, and a sinker connecting line fixing point. The bracket body is made of hard metal such as stainless steel wire, and its function is to support the overall load-bearing structure of the elastic stretching exercise frame. It includes the main line guide hole, the elastic arm connection point, and the sinker connecting line fixing point. The main line guide hole is a horizontal hole located at the upper end of the bracket body, on the same side as the elastic arm. Its function is to allow the main line to pass through the main line guide hole and connect to the elastic arm traction point. The elastic arm connection point is located between the main line guide hole and the sinker connecting line fixing point on the bracket body, and is connected to the main line guide hole. Located on the same side of the support body, this is the fixing point for the elastic arm. The sinker connection line fixing point is located at the lower end of the support body, connecting the sinker connection line. The elastic arm consists of a memory elastic component and a swing arm. The memory elastic component is made of a highly elastic metal wire such as a spring or nickel-titanium memory alloy wire. One end is horizontally positioned at the elastic arm connection point on the support body, and the other end is connected to the swing arm. The bending force is set to be less than the bending force of the swing arm, and also less than the weight of the sinker in the water. Its function is to use its elasticity to allow the main line to pull the memory elastic component of the elastic arm through the traction point, causing it to bend and return to its original position, thus creating a reciprocating motion of the swing arm. The arm, located at the other end of the main body connecting the memory elastic component, is the component that drives the leader line and the hook attached to it to swing. It consists of a swing arm body, elastic arm traction points, and elastic arm leader line connection points. The swing arm body is made of a highly elastic metal wire, such as stainless steel. The elastic arm traction points are multiple connection points on the swing arm body that connect to the main line, depending on the weight of the sinker and the required pulling force. The purpose of having multiple elastic arm traction points on the swing arm body is that when the angler selects a heavier sinker, the main line is connected to the elastic arm traction point closest to the memory elastic component, preventing the memory elastic component from being damaged due to insufficient elasticity upon recovery. Once the main line is bent, it cannot return to its original shape, causing the swing arm to lose its reciprocating motion function. When anglers need to cast far and choose a lighter sinker, they connect the main line to the elastic arm traction point near the end of the elastic arm leader connection point. According to the principle of leverage, the farther away from the memory elastic component, the smaller the force that can pull the swing arm. As long as the main line is subjected to a pulling force less than the weight of the sinker in the water, it can pull the memory elastic component to bend, causing the swing arm to drive the leader and the hook to swing back and forth. The elastic arm leader connection point is the connection point at the top of the swing arm body that connects to the leader. Its function is that when the swing arm is pulled by the main line and swings, the leader and the hook at the other end of the leader will swing back and forth in the water through the elastic arm leader connection point.
[0006] The leader line is a fishing line with a smaller diameter and tensile strength than the main line. One end of the leader line is connected to the leader line connection point of the elastic arm, and the other end is connected to the fish hook.
[0007] A fishhook is a hook that anglers choose based on the size of the target fish.
[0008] The sinker connecting line is a fishing line with a tensile strength less than the main line. One end of the sinker connecting line is connected to the sinker connecting line fixing point, and the other end is connected to the sinker.
[0009] A fishing sinker is a metal weight with a specific gravity greater than water, chosen by anglers based on different fishing grounds, fishing methods, water flow speed, and fishing depth.
[0010] Several usage methods and principles of elastic stretch biomimetic swing hook assemblies: In boat fishing, when the fishing boat slightly rocks and sways with the waves, the fishing rod fixed to the gunwale swings accordingly. The main line experiences tension from the rod, which repeatedly pulls the elastic arm traction point through the main line guide hole. This causes the elastic arm's memory elastic component to bend under force and then return to its original shape. The elastic arm, through the elastic arm leader connection point at its end, drives the leader line and the hook at the other end of the leader line to swing, making the bait on the hook move back and forth in the water like a live bait. In shore fishing with fixed casting, when the wind blows and the rod swings, the main line experiences tension from the rod, which repeatedly pulls the elastic arm through the main line guide hole. The elastic arm's memory elastic component bends under force and then returns to its original shape. This causes the elastic arm to swing through the elastic arm leader connection point at its end, driving the leader line and the hook at the other end of the leader line to oscillate. When fishing from the shore using a float, the main line is pulled up and down by the waves, causing the float to move. This pulls the elastic arm's traction point repeatedly through the main line guide hole, causing the memory elastic component of the elastic arm to bend under force and then return to its original shape. This causes the elastic arm to swing through the elastic arm leader connection point at its end, driving the leader line and the hook at the other end of the leader line to oscillate, thus achieving the dynamic biomimetic effect of the bait. In practice, multiple elastic stretch biomimetic oscillating hook assemblies can be connected in series using fishing line of the same diameter as the main line.

[0016] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, its characteristic is that it is composed of a main line 1, an elastic tension frame 2, a leader line 3, a fish hook 4, a sinker connecting line 5, and a sinker 6. The main line 1 passes through the main line guide hole 10 at the upper end of the elastic tension frame 2 and connects to the elastic arm traction point 16. One end of the leader line 3 is connected to the elastic arm leader line connection point 17, and the other end is connected to the fish hook 4. One end of the sinker connecting line 5 is connected to the sinker connecting line fixing point 12 of the elastic tension frame 2, and the other end is connected to the sinker 6. When the main line 1 is under force, the main line 1 passes through the main line guide hole 10 of the elastic tension frame 2 and applies the tension to the elastic arm traction point 16. Utilizing the elasticity of the memory elastic component 13 of the elastic arm 8, the elastic arm 8 is pulled to swing. The elastic arm 8 pulls the fish hook 4 to swing through the leader line 3 at its end, causing the bait on the fish hook 4 to move back and forth.
[0017] like Figure 1 As shown, main line 1 is the fishing line configured by the angler according to the size of the target fish.
[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the elastic tension exercise frame 2 consists of a main line guide hole bracket and a sinker connecting line bracket 7 and an elastic arm 8. The main line guide hole bracket and sinker connecting line bracket 7 consists of a bracket body 9, a main line guide hole 10, an elastic arm connection point 11, and a sinker connecting line fixing point 12. The bracket body 9 is made of hard metal such as stainless steel wire, and its function is to support the overall force-bearing structure of the elastic tension exercise frame 2. The main line guide hole 10, the elastic arm connection point 11, and the sinker connecting line fixing point 12 are provided. The main line guide hole 10 is a hole horizontally set at the upper end of the bracket body 9 and is set on the same side as the elastic arm 8. Its function is to allow the main line 1 to pass through the main line guide hole 10 and connect to the elastic arm traction point 16. The elastic arm connection point 11 is set at the connection point between the main line guide hole 10 and the sinker of the bracket body 9. The connection fixing point 12, located on the same side of the bracket body 9 as the main line guide hole 10, is the fixing point for fixing the elastic arm 8. The sinker connecting line fixing point 12 is located at the lower end of the bracket body 9 and is the connection point for connecting the sinker connecting line 5. The elastic arm 8 consists of a memory elastic component 13 and a swing arm 14. The memory elastic component 13 is made of a highly elastic metal wire such as a spring or nickel-titanium memory alloy wire. One end is horizontally set on the elastic arm connection point 11 on the bracket body 9, and the other end is connected to the swing arm 14. The bending force is set to be less than the bending force of the swing arm 14, and also less than the weight of the sinker 6 in the water. Its function is to use its elasticity to make the main line 1 pull the memory elastic component 13 of the elastic arm 8 through the elastic arm traction point 16. After bending, it returns to its original posture, causing the swing arm 14 to move back and forth. The swing arm 14 is located at the other end of the connection bracket body 9 of the memory elastic component 13. It is the component that drives the leader line 3 and the hook 4 attached to the leader line 3 to swing. It consists of the swing arm body 15, the elastic arm traction point 16, and the elastic arm leader line connection point 17. The swing arm body 15 is made of a highly elastic metal wire, such as stainless steel wire. The elastic arm traction point 16 is set on the swing arm body 15 as multiple connection points connecting the main line 1 according to the different pulling forces required by the different weights of the sinker 6. The function of setting multiple elastic arm traction points 16 on the swing arm body 15 is that when the angler selects a heavier sinker 6, the main line 1 is connected to the point closer to the memory elastic component 13. At the elastic arm traction point 16, to prevent insufficient elasticity of the memory elastic component 13 from causing the swing arm 14 to bend after being pulled by the main line 1 and unable to return to its original shape, thus losing its reciprocating motion function, when the angler needs to cast far and chooses a lighter sinker 6, the main line 1 is connected to the elastic arm traction point 16 near the end of the elastic arm leader connection point 17. According to the principle of leverage, the farther away from the memory elastic component 13, the smaller the force that can pull the swing arm 14. As long as the main line 1 is subjected to a pulling force less than the weight of the sinker 6 in the water, the memory elastic component 13 can be bent, causing the swing arm 14 to drive the leader 3 and the hook 4 to swing back and forth. The elastic arm leader connection point 17 is the connection point for connecting the leader 3 at the top of the swing arm body 15.Its function is that when the swing arm 14 is pulled by the main line 1 and swings, it drives the leader line 3 and the hook 4 at the other end of the leader line 3 to swing back and forth in the water through the elastic arm leader line connection point 17.
[0019] like Figure 1 , Figure 5 As shown, the leader 3 is a fishing line with a smaller diameter and tensile strength than the main line 1. One end of the leader 3 is connected to the elastic arm leader connection point 17, and the other end is connected to the hook 4.
[0020] like Figure 1 As shown, hook 4 is the hook that the angler chooses based on the size of the target fish.
[0021] like Figure 1 , Figure 4 As shown, the sinker connecting line 5 is a fishing line with a tensile strength less than that of the main line 1. One end of the sinker connecting line 5 is connected to the sinker connecting line fixing point 12, and the other end is connected to the sinker 6.
[0022] like Figure 1 As shown, sinker 6 is a metal sinker with a specific gravity greater than water, selected by anglers based on different fishing grounds, fishing methods, water flow speed, and fishing depth.
[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, this describes several usage methods and principles of the elastic stretch bionic swing hook assembly. During boat fishing, when the fishing boat slightly rocks and sways with the waves, the fishing rod fixed to the gunwale swings accordingly. The main line 1 experiences tension from the fishing rod fixed to the gunwale, which repeatedly pulls the elastic arm traction point 16 through the main line guide hole 10. This causes the memory elastic component 13 of the elastic arm 8 to bend under force and then return to its original shape. The elastic arm 8 then drives the leader line 3 and the hook 4 at the other end of the leader line 3 to swing through the leader line connection point 17 at its end. This causes the bait on the hook 4 to move back and forth in the water like a real bait. During shore fishing with fixed-point casting, when the wind blows and the fishing rod swings, the main line 1 experiences tension from the fishing rod, which repeatedly pulls the elastic arm traction point 16 through the main line guide hole 10. The elastic arm 8's memory elastic component 13 bends under force and then returns to its original shape. The elastic arm 8 drives the leader 3 and the hook 4 at the other end of the leader 3 to swing through the elastic arm leader line connection point 17 at the end. When fishing from the shore using a float, when the waves cause the float to move up and down, the main line 1 is pulled by the float. The main line guide hole 10 repeatedly pulls the elastic arm traction point 16, causing the elastic arm 8's memory elastic component 13 to bend under force and then return to its original shape. The elastic arm 8 drives the leader 3 and the hook 4 at the other end of the leader 3 to swing through the elastic arm leader line connection point 17 at the end, thus achieving the dynamic biomimetic purpose of the bait. In actual use, multiple elastic stretch biomimetic swing hook assemblies can be connected in series using fishing lines of the same diameter as the main line 1.
