Abstract
Description
[Technical Field]
[0001] The present invention relates to a bait-stealing prevention device for fishing, which stores and holds a baited hook in a basket to protect it from small fish and the like from being stolen by the bait-stealing hook until it reaches a set depth in the sea. [Background technology]
[0002] Traditionally, when fishing from rocky shores or breakwaters, the main method is to scatter bait at the point with a shovel, then cast a baited hook near the bait and let it drift with the tide in sync with the bait to catch a big fish.However, as the water temperature rises from spring to summer, many small fish called bait-eaters appear, and they often eat the bait before the float gets a bite.Inexperienced anglers in the summer hardly get a bite, so the angler's success depends on how they avoid these bait-eaters and get the baited hook to the big fish on the seabed.
[0003] If a baited hook is found naked by a bait-eater, the bait will be eaten immediately. Therefore, prior art documents show a device in which the opening is closed when the hook sinks, and when the target depth is reached, the rod is jerked up, which senses the water current and releases the stopper, releasing the baited hook into the sea.
[0004] However, these products are never seen in stores or on the internet, and it is thought that when a fish bites a baited hook, it feels resistance from the device and releases the baited hook due to the discomfort, which is why they were not recommended.
[0005] Additionally, there is a commercially available product called a long-distance casting cage (Non-Patent Document 1) which stores bait and baited hooks in the same or separate rooms and then throws them into the sea, but it is likely that with this product too, users feel resistance from the device and end up releasing the baited hooks due to the discomfort.

[0007] [Non-Patent Document 1] "Apollo Basket" manufactured by Sunny Shoji Co., Ltd. April 5, 2024 Internet search URL https: / / sany32.com / ec-cube / user_data / apollo_entou_kago Summary of the Invention [Problem to be solved by the invention]
[0008] To provide a fishing tool that can reach a set water depth while protecting a baited hook from being taken by small fish and minimizes the sense of incongruity when a fish bites the baited hook and is easy to use. [Means for solving the problem]
[0009] The present invention has been made to solve the above problems, and provides a baited hook prevention device as claimed in claim 1, in which baited hooks (13) are stored in a basket (2), the lid (3) is closed and the baited hook prevention device is dropped onto the water surface, but the basket (2) and lid (3) fall below the floating pipe (4) due to gravity until they hit the water, and underwater, the water resistance of the floating pipe weight (5) and the lid (3) causes the basket (2) to remain closed while sinking to the set water depth, i.e., the baited hook prevention device sinks, and when a float (hereinafter referred to as the "floating float") (15) with a float pet attached to a main line (16) comes into contact with a float stopper (14), the buoyancy of the basket (2) and the gravity of the lid weight (8) attached to the lid (3) causes the lid (3) to open, and the baited hooks (13) stored in the basket (2) are released into the sea, and the main line (16) connected to the guide float (15) is designed to pass through the inside of the floating pipe (4), and fish that bite the baited hooks (13) do so without feeling uncomfortable.
[0010] Furthermore, since the partition 10 within the cage is provided as in claim 2, the baited hooks 13 do not get tangled in the floating pipe 4 at the center of the cage 2, and the insertion of the baited hooks 13 into the cage 2 is easy and convenient.
[0011] Furthermore, in order to make the bait-taking prevention device for baited hooks more compact, as per claim 3, the underside of the lid 3 is made flat or nearly flat, which is more likely to receive water resistance when sinking. This allows the floating pipe sinker 5 to be set lighter, so that a guide float 15 with less buoyancy can be used, minimizing the discomfort felt by the biting fish. [Effects of the Invention]
[0012] The bait-stealing prevention device for baited hooks of the present invention sinks due to the gravity of the floating pipe sinker 5 after hitting the water, and the baited hook 13 is protected by the basket 2 and the lid 3 until the guide float 15 attached to the main line 16 comes into contact with the float stopper 14, so that it is protected from small fish and the like for a distance of several meters.
[0013] Furthermore, after the guide float 15 comes into contact with the float stopper 14, it is automatically released by the buoyancy of the basket 2 and the gravity of the lid weight 8 attached to the lid 3, and the baited hook 13 is released into the water. However, when a fish bites the baited hook 13, the main line 16 passes through the floating pipe 4, so there is only resistance from the guide float 15 and no resistance from the bait-taking prevention device on the baited hook, and the fish swallows it without any discomfort, which has the effect of increasing the catch.
[0014] Furthermore, when inserting the baited hook 13 into the cage 2, the provision of the partition wall 10 within the cage makes it easy to insert and it is less likely to become tangled in the floating pipe 4 at the center.
[0015] When a fish gets caught on the hook, there is no particular problem when it is pulled up because the upper part of the baited hook's anti-bait device body is conical in shape, which is less susceptible to water resistance. [Brief explanation of the drawings]

[0017] Hereinafter, an embodiment of the present invention will be described with reference to Figures 1 to 7. First, a method of setting up the fishing reel attached to the fishing rod to the terminal fishing hook, including the bait-tipped hook anti-bait device body, will be shown. The fishing line 16 wound on the fishing reel is passed through the fishing rod guide rail, and a float stopper 14 is attached to the water depth where the pulled-out line 16 is desired to be set.The line is then passed through the guide float 15 (more precisely, through the hole in the float pet attached to the guide float 15 or the hole in the through-hole floating float), and then through the floating pipe 4 (from the upper locking ring 6 side to the lower locking ring 7 side) of the bait-tipped hook bait-prevention device body, and then the line 16 is tied to one of the rings of the swivel 17. Then, a line 18 is tied to the other loop of the swivel 17 tied to the main line 16, and a baited hook 13 is attached to the end of the line 18.
[0018] Next, we will explain how to use the bait-hook bait-taking prevention device itself and the condition around it. First, the upper part of the bait-tipped hook bait-prevention device body is held downward, and with the lid 3 open, the baited hook 13 is inserted along the inner basket partition 10 inside the basket 2, and the leader 18 near the base of the hook is aligned with the leader fixing hole 12, and the lid 3 is closed. Next, while holding the upper locking ring 6, turn it in the forward direction, and the basket 2, while still closed by the lid 3, will come into close contact with the floating pipe sinker 5 below, and the main body of the bait-tipped hook bait-prevention device will come to rest at the swivel 17 connecting the main line 16 and the leader 18.
[0019] Next, the bait-equipped hook anti-bait device itself is released and thrown into the fishing spot. As soon as it hits the water, the basket 2, while remaining closed by the lid 3, moves to the upper locking ring 6 attached to the top of the floating pipe 4, and due to the gravity of the floating pipe weight 5 and the water resistance of the underside of the lid 3, the basket 2 sinks to the seabed while remaining closed.
[0020] When the guide float 15 attached to the main line 16 that passes through the main body of the baited hook anti-baiting device eventually comes into contact with the float stopper 14, the basket 2 of the main body of the baited hook anti-baiting device remains in close contact with the upper locking ring 6 due to its own buoyancy, and the lid 3 moves downward due to the gravity of the lid weight 8, opening the basket 2 and releasing the baited hook 13 inside into the water.
[0021] When a fish bites the baited hook 13, the fishing line 16 penetrates the floating pipe 4 of the bait-taking prevention device body of the baited hook, so the fish does not feel the resistance of the bait-taking prevention device body of the baited hook and does not let go of the baited hook 13. Furthermore, when pulling up the fish, the upper part of the bait-attached hook's anti-bait device body has a conical shape, so the fish can be pulled up without much water resistance.
[0022] Next, an embodiment of the present invention will be described. The main body of the bait-tapping hook bait-prevention device is arranged from top to bottom in the order of basket 2, lid 3 and floating pipe weight 5, with floating pipe 4 passing vertically through all of these basket 2, lid 3 and floating pipe weight 5, with the uppermost upper locking ring 6 fixed to the floating pipe 4 and the lowermost lower locking ring 7 also fixed to the floating pipe 4.
[0023] First, the basket 2 is made of resin that is slightly lighter than water, and the basket internal partition 10 that divides the internal space vertically is shaped to cover the floating pipe 4 and has a through hole that allows the floating pipe 4 to move freely up and down. The external shape is cylindrical with a conical upper part and a large opening at the bottom that fits the convex part above the lid 3, and the specific gravity of the basket 2 including the basket internal partition 10 is preferably about 0.8 to 1. In addition, an air exhaust port 9 for releasing air accumulated inside the basket 2 is arranged near the top, an intake and drainage port 11 is arranged on the lower wall, and an inverted U-shaped line fixing hole 12 is provided on the lower side of the corner chamber divided by the partition wall 10 inside the basket to prevent the line 18 near the hook from shaking.
[0024] Next, lid 3, which opens and closes the large opening at the bottom of basket 2, is circular with the same circumference as the cylindrical bottom edge of basket 2, with a convex top surface that fits into the concave part of the bottom edge of basket 2, and the bottom surface is flat or nearly flat to increase water resistance when the baited hook anti-bait device itself sinks, with the central extension below it being cylindrical and encasing floating pipe 4, and the lowest part is shaped so that the conical shape of the upper edge of floating pipe weight 5 fits into it, and a ring-shaped lid weight 8 is attached to the cylindrical part below lid 3. Lid 3, including lid weight 8, is slightly heavier than water, and has a through hole that allows floating pipe 4 to move freely up and down.
[0025] Furthermore, the specific gravity of the lid 3 including the lid weight 8 is preferably about 1 to 1.3, and if the lid 3 is made of a material that is slightly heavier than water, the installation of the lid weight 8 may not be necessary.
[0026] Next is the floating pipe 4, which has an inner diameter of about 0.5 to 3 mm and is long enough to allow the basket 2 and lid 3 to move freely up and down. It is preferably made of resin, but metal is also possible.
[0027] The floating pipe weight 5 is basically bullet-shaped with the tip pointing downwards, and has a conical top edge that fits into the recess at the bottom of the lid 3, with a hole in the center that runs vertically through which the floating pipe 4 passes. The weight is set so that when the baited hook anti-bait device body sinks, the lid 3 of the basket 2, which is slightly lighter than water, does not open.
[0028] The upper retaining ring 6 is intended to prevent the basket 2, lid 3, and floating pipe weight 5 from falling off the floating pipe 4. It is preferably a ring-shaped piece made of resin or metal that is glued or screwed to the top of the floating pipe 4, but it can also be simply fixed with adhesive tape or formed integrally with the floating pipe 4.
[0029] The lower retaining ring 7 is intended to prevent the basket 2, lid 3, and floating pipe weight 5 from falling off the floating pipe 4. It is desirable that the lower retaining ring 7 be made of resin or metal and be glued or screwed to the bottom of the floating pipe 4, but it is also possible to simply fix it with adhesive tape or to form it together with the floating pipe weight 5 and screw it to the floating pipe 4.
[0030] As an additional note, the cage 2 may be bullet-shaped, and although the drawing shows four air exhaust ports 9 and four intake and drain ports 11, the size and number may vary depending on the size of the cage 2. The cage internal partition 10 that divides the internal space vertically is preferably shaped to cover the floating pipe 4 even when the cage is a single chamber, and is preferably installed from the center to one of the walls. Regarding the material of the basket 2, if a material heavier than water is used, this can be achieved by ensuring an air pocket inside or by filling it with foam material.
[0031] Furthermore, a prototype of the bait-tipped hook bait-taking prevention device of the present invention was made and initially its operation was confirmed in a bathtub. However, in order to further confirm its detailed operation by videotaping, a simple cylindrical aquarium was created using transparent vinyl with a diameter of approximately 22 cm and a height of 150 cm to observe its operation, and it was confirmed that it worked as expected.
