JP2023140247A - Releasing gaff - Google Patents

Abstract

To provide a releasing gaff which is, on the premise of a catch and release, for the purpose of removing a fishing hook so that a fish on the hook is free from extra damage and weakening and which is for quickly returning the fish off the hook back to water.SOLUTION: In view of only a fish mouth flap (cannula) and a lower jaw for a part to hook a gaff, the shape of a conventional gaff is reviewed. By making the hook part of a gaff miniaturized with a narrow material, the gaff is made easier to enter a fish mouth. With the inside dimension C of the hook part made smaller, strength is also maintained and the hook becomes harder to sting a part which is likely to be a mortal wound on a fish upper jaw. By setting a hook tip part at an angle D from H, the gaff is simply made easier to hook the fish mouth flap (cannula).SELECTED DRAWING: Figure 2

Description

This invention makes it difficult for the gaff to be applied to the part that would cause a fatal injury when releasing a caught fish, and also minimizes the damage to the fish when removing the hook from the fish and when letting the fish escape after removing the hook. Concerning tools to keep it in place.

In recent years, many anglers have released fish in consideration of resource conservation, but it would be nice if the hook could be easily removed without securing the fish, but the reality is that it is not possible to remove the hook easily every time. Therefore, if a fishing hook is caught in a difficult-to-remove location, nets or gaffs are often used to secure the fish and take away the fish's freedom to remove the hook. For small fish, fish-friendly nets are sold by various manufacturers, but for large fish, they often cannot fit into the net and a gaff is often placed over their mouths. There is no problem if you can successfully apply the gaff to the lower jaw, but there are many cases where the gaff ends up being applied to the upper jaw. Blood vessels are concentrated in the upper jaw, and there are many places where the puncture can be fatal depending on where it gets stuck. However, most of the gaffs currently on the market are used for pulling up fish to keep them, and there are no gaffs for releasing them, so gaffs that can be hung while avoiding areas where they can cause fatal injuries, etc. Because there is no such thing, they often unintentionally sting the fish's vital points.

According to the existing technology, it is necessary to carefully hang the gaff on the fish's mouth while avoiding the vital points of the fish. Another objective is to be able to easily and quickly return the fish to the water without weakening it after gaffing the fish and removing the hook.

In order to solve the above problems, we created a shape that allows the hook part of the gaff to easily enter the fish's mouth, making it difficult for the hook part to get caught in the vital parts of the fish, and yet easily cause fatal injuries such as the mouth of the fish. Create a shape that makes it easy to hook into difficult-to-reach areas.

When removing the gaff hook from a fish, the fish will become weak if it is delayed, so the gaff should be shaped so that it can be easily and reliably removed with one movement.

In the first invention, in order to make the hook part of the gaff easy to put into the fish's mouth without having to open its mouth wide, by using a material with a narrow diameter, it was possible to create a shape that makes it easy to put the hook part into the fish's mouth. In addition, although thinner materials are weaker in terms of strength, it is necessary to make the hooks smaller in order to make them easier to insert into the mouth and to prevent the hooks from getting stuck in areas that could cause fatal injuries. However, we were able to resolve the strength issue. The second invention makes it possible to easily hook the hook to the mouth of the fish, which is not a vital point, even if the fish does not open its mouth by pulling the hook out after pushing it into its mouth. In order to do this, a bent part H was provided and the tip of the hook was angled horizontally with respect to the gaff body, making it possible to easily hang the hook by pulling out the hook inserted into the mouth. . The third invention was able to easily remove the fish by twisting and pushing the gaff when removing the hook.

1 is an overall diagram and part names showing an embodiment of the present invention. FIG. 3 is a front, rear, left and right front end view of the embodiment of the present invention as seen from the lateral direction. FIG. 1 is a top and bottom view of an embodiment of the invention viewed from the longitudinal direction. This is an embodiment of this invention.

Embodiments of this invention are shown in FIGS. 1 to 4. Details will be explained with reference to the drawings.

The end of the rod A in FIG. 1 has a hook B shaped like the letter "J", and the hook can be either removable or fixed.

Figure 2: The inner dimension C of the hook B is between 10 mm and 100 mm, depending on the size of the target fish, and the angle D of the hook tip is between 5° and 60°, depending on the species and size of the target fish. match.
The diameter of the hook material is 6 mm to 12 mm.
The length of G is 1 to 3 times the length of C.
The length of K is 0.5 to 2.5 times the length of C.
The length of I is 0.5 to 2.5 times the length of C.
In the case of type (1), when releasing a fish (removing it and returning it to the water), push it out while turning the gaff body clockwise, and the fish will be released smoothly.
In the case of type (2), when releasing the fish (removing it and returning it to the water), push it out while turning the gaff body counterclockwise, and the fish will be released smoothly.
Since there are issues such as handedness, choose the one that is easier to use.
By having an angle of D, you can hook the hook anywhere other than the vital points of the fish by simply pulling it out without having to make any unnecessary movements such as twisting the gaff placed in the mouth.

Figure 3 In normal use, the distance E is the maximum reaching point from the end of the fish's mouth to the tip of the gaff, and the length F is adjusted to the species and size of the target fish.

Figure 4: The inner dimension C of the hook and the angle D of the tip are adapted to the target fish, making it difficult for the hook to stick anywhere other than the mouth of the fish.

It can be used in fields related to fishing equipment.

Claims (1)

At the end of the rod A, there is a removable or fixed hook B shaped like the letter J for hooking fish, and the internal dimension C of the hook is determined by the target fish species and fish. By adjusting the size, the possibility of the hook getting stuck in the part that would cause fatal injury is greatly reduced, and the damage caused to the fish when hooked is minimized. Or, by setting an angle D from H as a starting point so that it deviates to the left side, it will be easier to stick into the mouth of the fish, and by adjusting the length of G to match the target fish. A release gaff that makes it difficult for the fish to come off the gaff during the act of removing the hook.
