Abstract
Description
[Technical Field]
[0001] The present invention relates to a hydraulic jumping yaen used for squid fishing that allows a shaft with a hook to easily jump up. [Background technology]
[0002] This fishing gear, called a yaen, is used to catch squid. A baby squid bait is attached to a hook, then cast into the sea. When the squid bites, the line is threaded through the holes in the posts and cast out, reaching the squid and hooking it. Traditional yaen fishing gear includes a single shaft with a post on one end for the line, two or three hooks on the other, a second post near the first, and a plate in between. There are also straight types, as well as types without a plate. However, yaen fishing gear is always below the angler's level in the water, requiring a strong pull toward the surface to hook the bait, preventing it from bouncing up. There are also movable lift-up types, in which a shaft with a hook is welded to the hinge of the main body, and hydraulic lift-up types with a hydraulic plate on one end of a shaft with a hook and a hook on the other, but both require a strong pull to hook the bait and make it bounce up. The disadvantage of a yaen is that it is always below the angler, and a straight type yaen does not jump up even if you strike hard. [Prior art documents] [Patent documents]

[0004] Traditional yaen fishing involves bringing the squid clinging to the bait close enough to be seen, then casting the yaen. However, in situations where it's difficult to bring the squid close enough to be seen, such as when the distance is too great, the water is too deep, there are ripples, or the sea is murky, it takes too long to bring the squid close enough to be seen, and they may eat the bait and escape, or they may feel uneasy while being brought close enough to be seen, causing them to run away. Casting the yaen after bringing the squid close enough to be seen can cause the bait to drop off due to the sound of it hitting the water, making it difficult to time the cast. Another method involves attaching a different colored line to the line wound around the reel and casting it once the connection is visible, but this can be difficult to see at night. Even if you can see the squid's arrival, you still need to set the hook (pull it to hook the hook). If the pull is too strong, the bait will drop, and if it's too weak, it won't get caught on the hook. In light of these conventional drawbacks, the present invention aims to provide a yaen that can be brought close enough to the squid that it can be caught without having to set the hook, as the shaft with the hook will jump up and catch the squid. [Means for solving the problem]
[0005] A hydraulic spring-up yaen has a shaft with a first support pole at one end facing upward, a hinge with a rotatable pipe-shaped cylinder at the other end, a second support pole at the other end facing upward, a second support pole at the other end facing upward, a plate that receives water pressure and is attached to the shaft so that the second support pole can be passed through the line near the hinge and in a straight line with the first support pole, a plate that receives water pressure and is attached to the shaft so that the shaft faces downward, a balance weight at one end and at least two hooks at the other end, and a third support pole that faces upward between the hooks and the balance weight, and the shaft with hooks is welded and fixed to the cylinder of the shaft so that the hook direction is forward and the third support pole is forward of the hinge.
[0006] This invention is a hydraulic jump-up yaen equipped with a water pressure receiving plate on the shaft. The line is attached to the first and second support posts of the shaft and the third support post of the movable shaft with the hook, and cast into the sea toward the squid. At the same time, the line is reeled in with the reel, and the squid is drawn in. When it arrives, a pushing force acts on the yaen toward the angler, but when water pressure is applied to the water pressure receiving plate and it stops, a pushing force and a pulling force act on the third support post toward the angler, causing the shaft with the hook to jump up. By installing a balance weight behind the shaft with the hook, the shaft with the hook jumps up smoothly, and even if the line tension slackens, the shaft with the hook stays up for a longer time, making it a hydraulic jump-up yaen that catches the squid. [Effects of the Invention]
[0007] From the above explanation, it can be seen that with this invention, although yaen fishing is said to be difficult, by using a hydraulic jump-up yaen, anyone from beginners to veterans can enjoy yaen fishing. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION
[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0010] FIG. 1 is an overall view of a hydraulic jumping yaen according to the present invention, and FIG. 2 is a perspective view of a state in which a squid 12 has bitten a bait 13 attached to a hook 14. As shown in FIG. When the squid 12 bites the bait 13, the line 11 becomes taut, so the line 11 is placed on the long, oval rod-shaped supports of the first support 2, the second support 3, and the third support 4 as shown in Figure 4, and pulled downwards to the state shown in Figure 5, and the line is hooked and thrown into the sea.The line is then advanced toward the squid 12, attracting the squid 12 as it reaches it.When it reaches the squid, the shape of the water pressure receiving plate 5 located in the middle of the third support 3 and the second support can be a beginner's mark shape, or it can be round or oval, but it is important that it has a fold, and when it advances toward the squid 12, it is bent into a V shape so that water pressure is not applied, and it is colored so that it is easy for the angler to see.The water pressure receiving plate 5 located below receives the water pressure and the yaen in Figure 1 stops, and the third support 4 is pulled toward the second support 3 and the second support 2, and the line 11 becomes the state shown in Figure 6.The shaft 7 with the hooks jumps up as shown in Figure 3, and comes into contact with the first hook 9, the second hook 10, and the third hook 11.The squid 12 tries to escape to the opposite side of the angler, but it gets caught on the squid 12. At least two rake-shaped three-pronged hooks are required; providing multiple hooks makes it easier to hook the squid. The number and shape of the hooks are not limited to this embodiment and can be designed as appropriate. The shape of the weight 6 attached to the rear end of the hook-attached shaft 7 can be designed as appropriate, such as a date palm shape, rugby ball shape, spherical shape, or square prism shape. The weight of the weight 6 is designed to be neither too heavy (the hook rises too high) nor too light (the hook does not jump up or jumps up slowly when the squid breaks) depending on the overall balance of the yaen. The weight and shape of the weight 6 are not limited to this embodiment and can be designed as appropriate.
[0011] (About the hook) Rake-shaped three-pronged hook -Attached in three places The number of hooks should be at least two, and providing more than one makes it easier to hook the squid. The number and shape of the hooks are not limited to this embodiment and can be designed as appropriate.
[0012] (weight) A weight is attached to the rear end of the shaft with the hook. The weight shape can be designed as desired, such as a date palm, rugby ball, sphere, or square prism. The weight is designed to be neither too heavy (so that the hook rises too high) nor too light (so that the squid does not jump up or jumps up too slowly) depending on the overall balance of the yaen. The weight and shape of the weight are not limited to those in this example and can be designed as desired.
[0013] (post) Shape: Vertical oval The hole for threading the line has a notch as shown in Figure 4, making it easy to thread. When the hooked shaft is tilted and the third support of the shaft falls towards the second support, the holes in each support are made vertically oval so that the thread will be in a straight line through the first, second and third supports. Although the number of supports is explained as three, there should be at least two (one on the shaft with the hook and one on the shaft). There can be more than two.
[0014] (plate) The shape can be a beginner's mark, round, or oval, but it is important that there is a crease. When you first cast it and move it towards the squid, if it is too big it will create resistance in the water, so it is preferable that the tip is triangular. - It is convenient for users to apply color to the surface so that they can see their hands from a distance.
[0015] (Explanation of when to catch a squid) The present invention is a jump-up type yaen that has a water pressure receiving plate attached to the shaft. The line is attached to the first and second support posts of the shaft and the third support post of the movable shaft with the hook, and is then cast into the sea and advanced towards the squid. At the same time, the line is reeled in and the squid is drawn in. When the squid arrives, a pushing force is applied to the yaen towards the angler, and when water pressure is applied to the water pressure receiving plate, it stops, and at the same time, a pushing force and a pulling force are applied towards the angler on the third support post, causing the shaft with the hook to jump up. By attaching a balance weight to the rear of the hinge part of the shaft with the hook, the shaft with the hook stays up for a longer period of time even if the tension on the line slackens, resulting in a water pressure type jump-up yaen that catches the squid.
