(B) Prior Art The present applicant previously disclosed in Utility Model Publication No. 59-20052 a cage for catching fish etc. by means of a cage connected to a line.

The basket has an annular base ring that also serves as a weight, and both ends are pivoted to pivot joints provided at 180° opposite locations on the base ring, and one half of the base ring has two ends. 3 that can be folded freely from the circular part to the other semicircular part
A semicircular tension frame body, a hemispherical cage mesh body stretched around the base annular body and the tension frame body, and entry openings in the center of both sides of the cage mesh body. It is characterized by comprising an intrusion hole for fish, etc. with a non-returning part arranged in a cylindrical shape inside the net body.

Further, with this configuration, the cage for capturing fish and the like has good stability in the water, and can efficiently capture fish and the like in a normal posture at all times.

(c) Problems to be solved by the invention However, such cages for catching fish, etc. are still difficult to solve.
It had problems in the following points.

That is, as mentioned above, the cage has three semicircular tension ribs, but since each tension rib is approximately a perfect semicircle, the rising portions from the pivots at both ends are also curved. When the cage is assembled from a folded state to a used state, the cage net body becomes slack on both sides where entry openings are provided, and as a result, fish notice the presence of the cage and refrain from entering the cage. They were not able to catch enough fish.

The object of the present invention is to provide a cage for catching fish, etc., which can solve the above-mentioned problems.

(d) Means for solving the problem The present invention has a circular base ring that also serves as a weight, and both ends of the base ring are each pivoted to pivot joints provided at 180° opposite locations on the base ring. , and three semicircular tension ribs that can be freely folded from one semicircular part to the other semicircular part of the base ring, and a hemisphere stretched around the outer periphery of the base ring and the tension bones. In a cage for capturing fish, etc., which is composed of a shaped cage net body, an entry opening in the center of both sides of the cage net body, and an entry hole arranged in a cylindrical shape inside the cage net body, Each tension bone body has a pair of straight parts connecting the proximal ends to the pivot parts and extending upward in a figure-eight shape symmetrically and tilting toward the center, and two straight parts at both ends. and a semi-circular arc part connected to the upper end, and the position of the connection part between both straight parts and the semi-circular arc part is set at approximately the same height as the upper edge of the entry opening of the entry hole. This relates to a trap for catching fish.

(E) Function When using a cage for capturing fish, etc. having such a configuration, the fully tensioned frame body is rotated from the folded position to the frame forming position, the hemispherical cage net body is unfolded, and then both sides of the cage are rotated. Forms a cage for trapping fish, etc., which has a hole for entering the fish without returning to the container.

Therefore, in the present invention, each tension frame body has a pair of straight parts whose base ends are connected to the pivot part and extend at a substantially parallel interval, and a pair of straight parts whose both ends are connected to the upper ends of both straight parts. It is formed from a circular arc part, and a straight part, a semicircular arc part, and a connecting part,
Since it is made approximately equal to the upper edge of the entry opening of the entry hole, both side surfaces of each cage net can be pulled outward, and loosening on both sides of the cage mesh can be completely prevented. It is possible to capture fish, etc. without making them aware of the existence of the entry hole.

Moreover, in the present invention, the pair of straight parts forming each tension bone body connects the proximal end to the pivot part, and extends upward in a figure-eight shape symmetrically and tilting towards the center. Therefore, even if it is subjected to impact force from fish etc. or uneven force on deformed seabed ground, the tension frame body will not deform, and the cage net body will maintain its optimal form against intrusion by fish etc. can do.

(F) Effects With the configuration described above, the present invention can sufficiently improve the capture rate without making fish etc. aware of the existence of the capture cage, especially its entry hole.

(G) Examples The present invention will be explained in detail below based on examples shown in the attached drawings.

In Fig. 1, reference numeral 1 denotes an annular base ring, which is made of a pipe-shaped steel material of a constant weight.
It also functions as a weight using a constant weight.

Such a base ring 1 can be installed on the bottom of the water so that the lower part of its entire circumferential surface is in contact with the bottom of the water.

Further, the base ring body 1 has annular pivot parts 3, 3 formed at positions facing each other at 180 degrees, and three curved tension members 2, 2a are formed in the pivot parts 3, 3. ，
The proximal ends of the ribs 2b are rotatably connected to each other, and the tension members 2, 2a, 2b can be positioned at any of the proximal annular positions with the pivot portion 3 as the center, as shown in FIG. It can be folded freely into a semicircular part.

Further, in FIG. 1, 4 is a car net body, and the car net body 4 is stretched around the outer periphery of a car frame a formed by the base ring body 1 and the tension frame bodies 2, 2a, and 2b. has been done.

The mesh size of the cage mesh body 4 is preferably 13 to 15 knots, and the threads are made of single threads so as to receive as little resistance from the flow of water as possible.

In addition, entry holes 5 for fish and the like are opened on the front and rear sides of the cage net body 4, and two entry openings 5a are provided in the center of the same sides, facing each other.

The penetration hole 5 preferably has a diameter of about 7 to 12
cm, the optimal size is 9 cm in diameter,
This corresponds to the fact that the diameter of fish that are generally caught in cages, such as octopuses, conger eels, crabs, and oysters, is approximately 10 cm.

Further, in FIG. 1, reference numeral 6 denotes a non-returning portion provided at the inner end of the car of the penetration hole 5 and reinforced with a metal ring, and the non-returning portion 6 is the opening edge of the penetration hole 5 inside the cage. 5b, and the tip edge 6a of the non-returning part 6 is a free end with a mesh-forming single thread remaining, so that once fish etc. enter the cage body 4 through the entry hole 5, , penetration hole 5
This prevents them from returning to the outside of the cage.

Moreover, the tip end edge 6a of the non-returning portion 6 is made to be concentric with the inner opening edge 5b of the penetration hole 5 and located inside the inner opening circle 5a, so that the non-returning portion The inner circumferential surface does not return to the tip edge 6a of the penetration hole 5 so that it gradually tapers toward the tip edge 6a of the penetration hole 5, and the inner circumference of the penetration hole 5 is continuous. A non-returning portion 6 is formed so that the non-returning portion 6 projects laterally from the circumferential surface of the cage net 4, and the non-returning portion 6 is held laterally as an extension of the penetration hole 5. Even though the fish do not return from the entry hole 5 and instead enter the section 6, the fish do not become alarmed.

In the above basic configuration, the present invention provides a pair of straight parts s, s that connect each tension frame body 2a, 2b to the pivot part at the base end and extend at a substantially parallel interval, The semi-circular arc portion b is connected to the upper end of the portions s, s, and the connecting portion between the straight portions s, s and the semi-circular arc portion b is approximately formed through the penetration hole 5.
It is characterized in that the height is approximately equal to the upper edge of the entry opening 5a.

With this configuration, by rotating the tension members 2a, 2b from the folding position to the assembly position and fixing them, both sides of the cage net 4 can be adjusted to the straight parts s, 2b.
s can be pulled outward, completely preventing slack on both sides of the cage net body 4, and capturing fish, etc. without making the fish, etc. aware of the presence of the cage. be able to.

Preferably, the branching point between the straight portions s, s of each tension frame body 2a, 2b and the semicircular arc portion b is at the entry opening 5a of the entry hole 5 for fish etc. formed on the front and rear surfaces of the cage net body 4. It is desirable that the area be located one section of the mesh front and back above the upper edge of the net.

In addition, in FIG. 1, reference numeral 7 denotes tension threads provided on both side walls of the car net 4, and the tension threads 7 can further tension the car mesh 4. The presence of the cage net body 4 can be hidden from fish and the like.
