Description

[Detailed Description of the Invention] For example, when fishing for tuna using the longline fishing method, it is difficult to pull up the fishing line onto the boat because the tuna itself is heavy, and even if you try to pull it up, the mouth is cut and the hook comes off, making it expensive to catch. This resulted in the tuna being released into the ocean.

Previously, several workers used hook rods to hook and pull up the tuna, but this was a difficult task because the tuna itself was extremely heavy.

In this regard, the present invention relates to a large fish fishing device that can easily and reliably catch large fish caught on a hook, thereby increasing the amount of fish caught. be.

Several hook rods 3 are arranged radially around the lower part of the descent tube 2 that is inserted into the fishing line 1 and lowered into the sea. In the device for catching large fish that is caught and held by the hook and pulled up, the descending tube 2 is formed by combining two half members 2a, 2a, and one end side of the half members 2a, 2a is connected to the half member 2a.
, 2a are provided so that they can be opened and closed via an elastic mechanism a so that they are always in a closed state.

The hook rod 3 shown in the drawings has its base 3a fitted into fitting grooves 5 formed at regular intervals around the descent tube 2, and is pivoted by a pivot shaft so as to be able to vibrate freely.

The elastic mechanism a in the drawing uses a plate spring 6 made of stainless steel, plastic, etc., and is installed between the upper parts of half members 2a, 2a, and 7 is a set screw.

The half members 2a, 2a in the drawings have a protruding line 8 formed in the length direction of one end of one half member 2a, and a concave line 9 formed in the length direction of one end of the other half member 2a. The half member 2a is engaged with the strip 9.

2a is provided so that it can be opened and closed freely.

The descent tube 2 is provided with a locking device that locks the half members 2a, 2a in the closed state and releases them as necessary.

The locking device in this figure has a notch 10 slightly above the middle of the pivoting side of the descending tube 2 on the half member 2a.

2a, a guide plate 12 having guide holes 11.11 at both ends is provided in this notch 10 against the spring 13, and a pressing rod 14 is vertically attached to the center of the guide plate 12. The upper end of this pressing rod 14 protrudes from a fitting hole 16 formed by grooves 15, 15 at the joint of half members 2a, 2a, and
A pin 17.17 is vertically provided near one end on the pivot side of a, and a tapered portion 18.18 located above the notch 10 is connected to the lower end of this pin 17.17. A small-diameter protruding rod 19.19 smaller in diameter than the guide hole 11°11 is connected to the tip of the tapered portion 18.18, and this small-diameter protruding rod 19
．． 19 is shown embedded in the lower surface of the notch 10. For this purpose, when the pressing rod 14 is pressed and the guide plate 12 is lowered against the spring 13 as shown in FIG. 11.11 is located at the small diameter protrusion 19.19, a gap is formed between the small diameter protrusion 19, 19 and the guide holes 11, 11, and the half members 2a, 2 are moved by this gap.
A will be open on both sides.

(The larger the gap, the more the half members 2a, 2a
will be released to the public.

) Conversely, when the press rod 14 is released and the guide plate 12 rises, the tapered portions 18, 18 fit snugly into the guide holes 11, 11, so no gap is formed, and therefore the half member 2a
, 2a are kept closed and never open.

In the figure, 20 is a pulling rope, 21 is a rope mounting bracket, 2
2.22 is a rope introduction guide portion formed by cutting out the other end of the half member 2a, opposite to the pivoting side; 23 is a fixing hole.

Since the present invention is constructed as described above, when a large fish such as a tuna is caught on the fishing hook, the descending cylinder 2 fixed to the tip of the pulling rope 20 is immediately inserted onto the fishing line 1, and
If the product of the present invention is released, the descending tube 2 will suddenly descend along the fishing line 1 due to its own weight and collide with the fish head 4.

(In this case, increasing the thickness of the descent tube 2 makes it heavier, resulting in a sudden descent.

) At this time, the bases 3 of several hook rods 3 are placed around the lower part of the descent tube 2.
A is pivotally mounted so that the hook rod 3 can oscillate downward radially and vertically, so until the descent tube 2 collides with the fish head 4, the hook rod 3 vibrates upward due to water resistance and the umbrella is lifted. Although it is in an open state, due to the impact of the collision, several hook rods 3 are in a closed state, and the sharp tip portions 3b of the hook rods 3 bite firmly around the fish head 4 and hold it. I will do it.

Since the hoisting rope 20 is towed on board in this state, the sharp end portion 3b bites further into the fish head 4, and the large fish is no longer dropped. This means that large fish can be safely brought onto the boat and captured without having to be caught.

Therefore, by using the product of the present invention, it is possible to reliably catch and catch a large fish caught on a hook without dropping it.

In this case, when passing the fishing line 1 through the descent tube 2, the half member 2a
, 2a are opened against the elastic mechanism a, and after inserting the fishing line 1 from the opening in this state, by releasing the half members 2a, 2a, the half members 2a, 2a are closed, and the fishing line 1 is inserted into the descent tube 2. The half-part 2a will be threaded through, and in this case by means of a locking device.

Since the closed state of 2a is locked, the half member 2a is closed during use.
, 2a will open and the fishing line 1 will not come off, so it can be used with confidence.

In this case, by forming a rope introduction guide part 22 at one end of the half members 2a and 2a, the fishing line 1 can be easily lowered by simply pushing it into the rope introduction guide part 22 without opening the half members 2a and 2a. It becomes possible to pass it through the tube 2.

Conversely, when the fishing line 1 is to be removed from the descending tube 2, the locking device is released, the half members 2a and 2a are opened, and the fishing line 1 can be taken out from the opening in this open state.

In this way, it is extremely easy to pass the fishing line 1 through the descent tube 2 and to remove it, and once the fishing line 1 is passed through the descent tube 2.
When it is passed through, the elastic mechanism a reliably prevents the half members 2a and 2a from opening, so you can press the button during descent or pulling up, and the fishing line 1 will not come off, allowing you to catch large fish with excellent safety. It becomes a tool.

Furthermore, by making the whole of the present invention made of stainless steel, it becomes a large fish fishing tool that does not rust and can be used for a long time, and can also be manufactured by the half member 2a.

It is easy because it is only necessary to polymerize 2a and attach it to one end side so that it can be opened and closed via the elastic mechanism a, and it has isotropic characteristics that make it possible to mass-produce it and provide the product at a low cost. .
