Clip for fish trap for preventing ghost fishing}

The present invention relates to a fish trap clip for preventing ghost fishing. More specifically, it is installed on a fish trap to support an adjustment rope for adjusting the size of the escape port of the fish trap, and after a certain period of time, the fish trap is removed. It relates to a fish trap clip that can effectively prevent ghost fishing caused by lost fishing gear by allowing it to escape from the fish trap.

In general, traps are fishing gear used to catch fish such as octopus, octopus, crab, and eel in coastal waters.

As shown in Figure 1, the fish trap typically consists of a frame 20 made of metal forming a skeleton, and a net 30 surrounding the frame 20.

The frame 20 consists of a circular upper ring 21, a circular lower ring 23, and support bars 25 connecting the upper ring 21 and the lower ring 23 to each other. And in order to prevent deformation of the upper ring 21 and the lower ring 23, a center ring 27 is installed inside the upper ring 21 and the lower ring 23, respectively.

An outlet 37 that can be opened and closed is formed at the top of the net 30 so that the captured fish can be taken out. A string 38 is installed around the outlet 37 and has a structure that allows the outlet 37 to be opened and closed by tightening and loosening the twine 38. A ring 39 is connected to one side of the twine 38.

And on the side of the trap, a number of entry induction parts 15 are provided to allow fish to enter the inside of the trap. The entry induction part 15 is formed of a net or plastic molded product, and a number of it is installed at regular intervals on the side of the trap. The entry guide part 15 is formed so that the passage narrows as it progresses from the outside to the inside, and is structured to prevent fish from escaping to the outside through the entry guide part 15 again.

After putting bait to attract fish into the inside of the trap, when the trap is sunk into the sea, the trap settles on the bottom of the sea and attracts various fish, etc. The fish attracted by the bait are As they enter the inside of the trap through the entry guide, they become trapped in the trap.

Fish trap fishing involves placing traps in the sea for a long time and then pulling them up, so situations often occur where the traps fall off from the fishing line or fishing line and are lost underwater.

Marine life that enters the inside of a trap abandoned in the sea becomes trapped in the trap and dies over time. In addition, ghost fishing, in which marine life becomes trapped in the trap and dies, is continuously repeated as other marine life enters the trap to eat the dead marine life inside the trap. This type of ghost fishing not only causes loss of fishery resources, but also causes the lost fish traps to pile up on the sea floor, contaminating the spawning grounds and habitats of marine life.

To solve these problems, traps made of nets made of biodegradable materials are being developed. Republic of Korea Patent No. 10-0415812 discloses fishing gear using a biodegradable aliphatic polyester resin composition.

Such fishing gear naturally decomposes underwater after a certain period of time, which is effective in preventing ghost fishing, but it has the following problems.

First, nets made of biodegradable resin have the problem of low physical properties such as durability, brittleness, and tensile strength.

Second, biodegradable resin is expensive, so if the material of the net surrounding the entire trap is made of biodegradable resin, there is a problem that the cost of the trap increases significantly.

Third, the lifespan of a typical fish trap is usually 2 years, but if the decomposition time of the biodegradable resin is shortened, the function as a trap is lost earlier, resulting in the problem of having to frequently replace the trap net. In addition, if the decomposition time of the biodegradable resin is prolonged in order to maintain the function as a fish trap for a longer period of time, a problem arises in which ghost fishing continues during that period when the fish trap is lost.

In this way, many problems arise when making fish traps using nets made of biodegradable resin materials.

On the other hand, due to the nature of fishing gear, traps are easy to get inside and difficult to get out, so there is a problem in that even fry and small juveniles are captured, depleting fisheries resources.

In order to solve this problem and protect young individuals subject to protection under the Fisheries Resources Management Act, traps with an escape hatch through which only young individuals can selectively escape have recently been known.

Republic of Korea Patent No. 10-2234532 discloses a fishing trap with an escape hatch attached.

As shown in Figure 2, the fish trap described above can protect young individuals during normal fishing by providing an escape hatch 500 on the side through which young individuals can escape. However, these fishing traps also become a problem if they are lost underwater. In other words, young individuals can escape to the outside through an escape hatch, but adults cannot escape through a small escape hatch, so the problem of ghost fishing, where they are trapped inside the trap and die, still occurs.

1. Republic of Korea Patent No. 10-0415812: Biodegradable aliphatic polyester-based resin composition, fishing gear using the same, and manufacturing method thereof 2. Republic of Korea Patent No. 10-2234532: Fish trap with escape hatch attached

The present invention was created to improve the above problems, and by forming an escape hatch in the trap, it is possible to protect fish resources by allowing fry to escape to the outside during normal fishing, and at the same time, when lost in the water, not only fry but also adults. We aim to effectively prevent ghost fishing caused by abandoned fishing gear by allowing fish to escape.

Accordingly, the present invention reduces the size of the escape hatch during normal operation so that only fry can escape, and when the fish trap is lost, the size of the escape hatch is restored to allow even adult fish to escape, using an adjustment rope installed on the escape hatch. The purpose is to provide a clip for the fish trap for support.

The fish trap clip for preventing ghost fishing of the present invention for achieving the above object is formed with an adult escape port through which even adult fish can escape in the net of the trap, and is coupled to the net around the adult escape port to close the edge of the escape port. In the fish trap clip for supporting the control rope installed along, it is made of a naturally degradable material so that the support force of the control rope is lost after a certain period of time.

The fish trap clip includes a disc-shaped base plate, a center hole formed on the base plate into which a fixing line over which the coupling rope is inserted, and a center hole formed on the base plate to be connected from the edge of the base plate to the center hole. Provided with a guide slot.

The guide slot is formed to gradually become narrower in width from the edge of the base plate toward the center hole.

The base plate includes a center plate on which the center hole is formed, a side plate formed to surround the outside of the center plate so as to be spaced apart from the center plate, and a connecting rib connecting the center plate and the side plate.

The connecting rib is formed to be thinner than the center plate and the side plate so that it can be disassembled earlier than the center plate and the side plate.

A protruding fin portion is formed on the edge of the base plate so that it can be held by hand.

The fin portion is formed to gradually protrude in a direction away from the entrance of the guide slot.

As described above, the present invention can solve the problems of the conventional fish trap by allowing the clip to naturally decompose after a certain period of time while supporting the control rope installed in the adult escape hatch with a clip.

Therefore, during normal fishing, the control rope is supported by the clip, so the adult escape hatch is reduced, so only the fry can escape to the outside, and when the fish trap is lost, the clip naturally decomposes after a certain period of time, securing a widened adult escape hatch, so that the adult escape hatch is secured. Ghost fishing that occurs due to this can be prevented in advance.

Hereinafter, a fish trap clip for preventing ghost fishing according to a preferred embodiment of the present invention will be described in detail.

Referring to Figures 3 to 8, the trap is installed on the main body 10 so that fish can enter the main body 10 and the inside of the main body 10 from the side of the main body 10. An entry guide part 15 formed with a passage that gradually becomes narrower in the direction, and a net 30 so that fish that enter the inside of the main body 10 through the entry guide part 15 can escape to the outside of the main body 10. An adult escape port (35) formed in the main body (10), a reduction means for reducing the size of the adult escape port (35) so that only small-sized fish can escape out of the main body (10) during normal operation, and In case of loss, a means to prevent ghost fishing is provided to restore the size of the adult escape port 35, which has been reduced by the reduction means, so that even adult fish can escape.

The main body 10 includes a frame 20 and a net 20 surrounding the frame 20.

The frame 20 forms the skeleton of the main body 10 and is formed in a circular shape in the illustrated example. In addition, of course, the frame can be formed in various shapes such as square, rectangular, cylindrical, or spring-shaped.

The frame 20 is made of a metal material with high rigidity. The frame 20 includes a circular upper ring 21, a circular lower ring 23, and support bars 25 connecting the upper ring 21 and the lower ring 23 to each other. And in order to prevent deformation of the upper ring 21 and the lower ring 23, a center ring 27 is installed inside the upper ring 21 and the lower ring 23, respectively.

A net 30 is covered outside the frame 20. The net 30 surrounds the top, bottom, and sides of the frame 20. The net 30 can be made by weaving threads of common nylon material. Additionally, a net made by weaving threads of biodegradable materials can be used. The net 30 surrounds the frame 20 and forms a trapping space inside the main body 10 where fish such as octopuses, octopuses, crabs, and eels are captured.

The net 30 is fixed to the frame 20 using a fixing rope 31. That is, the fixing rope 31 is threaded through the nose of the net 30 adjacent to the upper ring 21 and the lower ring 23 and wound spirally around the upper ring 21 and the lower ring 23 to form a net ( 30) is fixed to the upper ring (21) and lower ring (23).

An outlet 37 that can be opened and closed is formed at the top of the net 30 so that the captured fish can be taken out. A string 38 is installed around the outlet 37 and has a structure that allows the outlet 37 to be opened and closed by tightening and loosening the twine 38. A ring 39 is connected to one side of the twine 38.

Although not shown, if the real-name fishing gear system is introduced, an identification tag or tag containing fishing gear information may be attached to the net 30.

One or more entry guide units 15 are installed on the side of the main body 10. In the example shown, three entry guide units 15 are installed at 120-degree intervals. The entry guide portion 15 may be made of a net or a plastic product made by injection molding synthetic resin.

The main body 10 and the entry guide 15 described above have a typical structure.

The adult escape port 35 is formed in the main body 10. For example, the adult escape port 35 may be formed on the side, top, or bottom of the main body 10.

In the illustrated example, the body escape port 35 is formed on the side of the main body 10. In this case, the assemblage exit 35 is placed between the entry guides 15. In the illustrated example, one adult exit 35 is formed, but of course, two or more can be formed at regular intervals. In addition, the adult exit 35 is formed in a square shape, but of course it can also be formed in a circular shape, oval shape, rod shape, etc. In addition, the adult escape port 35 may not only be located in the center of the side of the main body 10, but may also be located away from the center and biased toward the upper or lower portion.

The adult escape port 35 can be formed by cutting out a portion of the net 30 located on the side of the main body 10. The adult escape port 35 is formed of a size sufficient to allow the adult fish to escape. For example, the adult escape port 35 may be formed to have a size of 5 to 20 cm in width and 2 to 10 cm in height.

Fish that have entered the inside of the main body 10 through the entry guide 15 can escape to the outside of the main body 10 through the adult escape port 35. At this time, not only small fish such as fry or juveniles but also adult fish can escape to the outside of the main body 10 through the adult escape port 35.

In this way, since adult fish can escape to the outside of the main body 10 through the adult escape port 35, it is necessary to prevent adult fish from escaping through the adult escape port 35 during normal operation. Accordingly, a reduction means is provided.

The reduction means serves to reduce the size of the adult escape port (35) so that only small-sized fish can escape out of the main body (10) during normal operation. Here, normal fishing refers to a situation in which fishing traps are not lost and fishing activities to capture target fish using traps are possible normally.

By the reduction means, the adult escape port 35 is reduced to a size that allows only small fish such as fry or juveniles to escape.

As an example of the reduction means, a barricade 40 is installed to block the assemblage exit 35 and has one or multiple mini holes 43, and the barricade 40 is connected to the net 30 around the assemblage exit 35. It is provided with an adjustment rope (50) for coupling.

The barricade (40) is installed to block the Eucharistic exit (35). The barricade 40 may be made of metal or synthetic resin material.

The barricade 40 may be provided with a plate-shaped blocking plate 41 and side ribs 45 and 47 formed at the edges of the blocking plate 41.

A mini hole 43 is formed in the blocking plate 41. One or more mini holes 43 may be formed. The mini hole 43 is used as an escape passage for small fish such as fry or juveniles. Therefore, the mini-hole 43 is smaller than the size of the adult escape port 35. As an example, the mini hole 43 may be formed to have a size of 2 to 10 cm in width and 1 to 5 cm in height. Depending on the type of target fish, the size of the mini hole can be changed appropriately. Additionally, depending on the type of target fish, the shape of the mini hole can be appropriately changed to a circular or oval shape in addition to a square shape.

The blocking plate 41 is preferably formed to be curved around the central portion. This is to facilitate close contact with the net 30 located on the side of the main body 10.

Side ribs 45 and 47 are formed at the edges of the blocking plate 41. In the illustrated example, side ribs 45 and 47 are formed at the upper and lower edges of the blocking plate 41, respectively. The side ribs 45 and 47 are formed to gradually become wider as they proceed from both ends of the blocking plate 41 toward the center. The side ribs 45 and 47 are also formed to be slightly curved relative to the central portion.

For convenience of explanation, the two side ribs can be divided into an upper side rib (45) and a lower side rib (47). The upper side rib 45 is formed on the upper edge of the blocking plate 41, and the lower side rib 47 is formed on the lower edge of the blocking plate 41.

A binding hole 46 for binding the adjustment rope 50 is formed in the center of the upper side rib 45. And the lower side rib 47 is formed with a plurality of rope insertion holes 48 through which the adjustment rope 50 passes.

The control rope 50 is coupled to the net 30 by threading it around the left and right and upper and lower edges of the adult escape port 35. At this time, at the lower edge of the adult escape port 35, the control rope 50 is moved alternately in and out of the lower side rib 47 and is threaded together with the mesh. Therefore, only the lower part of the barricade 40 is supported by being coupled to the net 30. Both ends of the control rope (50) are knotted (51) to prevent the lower part of the barricade (40) from being separated from the net (40).

In this way, with the adjustment rope 50 tied to the mesh around the edge of the adult escape port 35, the adjustment rope 50 is connected through the binding hole 46 from the inside to the outside of the upper guide rib 45 as shown in FIG. After passing it, it is pulled upward and hung on the fixing line 60, and the barricade 40 blocks the adult escape port 35 as shown in FIG. 3. And when the control rope 50 is separated from the fixing line 60, the barricade 40 blocking the adult escape exit 35 is tilted outward and the adult escape exit 35 is opened.

The ghost fishing prevention means serves to restore the size of the adult escape port 35 that has been reduced by the reduction means. This is to ensure that even adult fish can escape if the trap is lost.

In this embodiment, since the barricade 40 blocks the adult escape port 35, the purpose of the ghost fishing prevention means is to allow the barricade 40 to open the adult escape port 35. As the assemblage exit 35 is opened, the assemblage exit 35, which was blocked by the barricade 40, is restored to its original size.

The ghost fishing prevention means includes a fixed line (60) installed on the main body (10), a clip (65) installed on the fixed line (60) to support the reduction means, and released from the fixed line (60) after a certain period of time. do.

As the fixing string (65), you can use a thin string made of metal wire or synthetic resin. The fixing line 65 is fixed to the main body 10. For example, it may be fixed to the net 30 of the main body 10 or to the frame 20. In the illustrated example, the fixing line 65 is fixed to the net 30.

A locking protrusion 61 is formed at the end of the fixing line 60. The locking protrusion 61 may be formed in a spherical shape. In this case, the diameter of the locking protrusion 61 is formed to be larger than the diameter of the fixing line 60.

The clip 65 of the present invention is installed on the fixing line 60. The clip 65 is installed on the fixed line 60 so that the control rope 50 can be caught on the fixed line 60.

The illustrated clip 65 includes a disk-shaped base plate 67, a center hole 68 formed in the base plate 67 into which the fixing string 60 is inserted, and a center hole at the edge of the base plate 67. It is provided with a guide slot (69) formed in the base plate (67) to be connected to (68).

The base plate 67 is formed in the shape of a thin disk. For example, the base plate 67 may be formed to have a diameter of 5 to 20 mm and a thickness of 0.5 to 3 mm.

The center hole 68 is formed in a circular shape. The center hole 68 is formed through the base plate 67. The diameter of the center hole 68 is larger than the diameter of the fixing line 60 and smaller than the diameter of the stopping protrusion 61.

The guide slot 69 is a passage through which the fixing line 60 moves to the center hole 68. Therefore, the fixing line 60 is moved through the guide slot 69 and inserted into the center hole 68. The guide slot 69 is formed to connect from the edge of the base plate 67 to the center hole 68.

The guide slot 69 is formed to gradually become narrower in width from the edge of the base plate 67 toward the center hole 68. The narrowest part of the guide slot (69) is the part where the guide slot (69) and the center hole (68) come into contact. The width of this part is smaller than the diameter of the fixing line 60.

When the fixing line 60 is pushed into the guide slot 69, the guide slot 69 is forcibly opened and the fixing line 60 is inserted into the center hole 68.

The clip 65 described above is made of biodegradable resin.

As biodegradable resin, natural biodegradable resin, microbial biodegradable resin, and chemically synthesized biodegradable resin can all be used.

Examples of biodegradable resins include polyethylene succinate (PES), polybutylene succinate (PBS), polybutylene adipate terephthalate (PBAT), Polyethylene adipate terephthalate (PEAT: polyethylene-co-adipate-co-terephthalate), polybutylene succinate terephthalate (PBST: poly butylene-co-succinate-co-terephthalate), polyethylene succinate terephthalate (PEST: poly ethylene-co-succinate-co-terephthalate), polybutylene succinate adipate terephthalate (PBSAT: poly butylene-co-succinate-co-adipate-co-terephthalate), polyethylene succinate adipate terephthalate (PESAT: poly Any one or a mixture of two or more of ethylene-co-succinate-co-adiapte-co-terephthalate), polylactic acid (PLA), and poly caprolactone (PCL) can be used.

These biodegradable resins can be naturally decomposed after a certain period of time in water. The decomposition time can be adjusted in various ways depending on the type of resin and the addition of additives.

It is suitable for biodegradable resin to manufacture the clip 65 that decomposes after about 10 to 50 days. In addition, since the period of time that fish can survive without food in the trap varies depending on the fish species, the natural decomposition time of the clip can be set from 50 days to within 1 year.

If the clip is made of biodegradable material that decomposes after about 30 days, the clip 65 decomposes naturally after 30 days, detaches from the fixing rope 60, and loses the supporting force of the adjustment rope 50. Therefore, during normal operation, the clip 65 needs to be replaced before the disassembly period of the clip 65 expires. During normal operation, the clip (65) is replaced with a new one at regular intervals and the trap is used.

Additionally, in addition to biodegradable resins, metals can be cited as examples of materials that can be naturally degraded. For example, the clip 65 can be made from a thin metal plate such as iron, copper, or zinc. These metals are easily oxidized or corroded in water, especially sea water, and are easily decomposed over a certain period of time.

When the clip 65 is disassembled and the clip 65 is separated from the fixing line 60, the control rope 50 is separated from the fixing line 60 and the barricade 40 moves out of the main body 10 as shown in FIG. As it is folded, the adult escape port (35) is opened.

In this way, in the state where the adult escape port 35 is blocked with the barricade 40 and the control rope 50 connected to the barricade 40 is supported by the clip 65 of the present invention, the clip 65 is clipped after a certain period of time has elapsed. (65) By allowing it to naturally decompose, all problems with conventional fish traps can be solved.

During normal operation, fish resources can be protected by allowing fry to escape to the outside through the mini hole 43 formed in the barricade 40. In addition, when the fish trap is lost in the water, the barricade 40 blocking the adult escape exit 35 is removed by the clip 65 of the present invention, which naturally decomposes after a certain period of time, thereby creating an adult escape exit 35 through which the adult can escape. Since , ghost fishing caused by abandoned traps can be prevented in advance.

The adult escape port (35) is blocked with a barricade (40), the control rope (50) connected to the barricade (40) is supported by the clip (65) of the present invention, and the clip (65) is made of biodegradable resin, so the following It has advantages.

First, the size of the clip is very small, with a diameter of 5 to 20 mm and a thickness of 0.5 to 3 mm. Therefore, the amount of expensive biodegradable resin used can be minimized. Compared to the conventional method where the entire net surrounding the fish trap is made of biodegradable resin, the manufacturing cost of the fish trap is more than doubled, the present invention can significantly reduce costs.

Second, when the entire net surrounding the fish trap is made of biodegradable resin as in the past, the function of the fishing gear is lost when the biodegradable resin decomposes. Therefore, there is a problem that the entire net must be replaced periodically. On the other hand, in the present invention, it is sufficient to make only the clip with biodegradable resin, so only the clip needs to be replaced periodically. Compared to periodically replacing the entire net, periodically replacing only the clips is greatly advantageous in terms of cost and time.

Third, if the entire net surrounding the trap is made of biodegradable resin as in the past, ghost fishing can be prevented when the trap is lost. However, after the decomposition time of the biodegradable resin has elapsed, even if the lost trap is recovered, the trap can be reused. This is impossible. On the other hand, the present invention can prevent ghost fishing when a trap is lost, and at the same time, when the lost trap is recovered after the clip disassembly time has elapsed, the net of the trap is intact, so the trap can be reused immediately by simply attaching a new clip. do. In particular, this advantage is very important in the reality that the possibility of reuse of lost traps is higher if they are returned to their owners due to the introduction of the real-name fishing gear system in the future.

Figure 9 shows another view of the fish trap. The reduction means applied in FIG. 9 consists of only an adjustment rope 50 without a barricade.

Referring to Figure 9, the control rope 50 is coupled to the net 30 by threading it around the left and right and upper and lower edges of the adult escape port 35. With the control rope (50) tied to the mesh around the edge of the adult escape hatch (35), hang it on the part of the control rope (50) located at the bottom of the adult escape hatch (35), then pull it upward and hang it on the fixing line (60). The control rope 50 is supported by a clip 65.

In Figure 9, one large adult exit 35 is divided into two small adult exits by the control rope 50. And when the clip 65 naturally decomposes, the control rope 50 is separated from the fixing line 60, and the adult escape port 35 can be expanded widely again.

And Figures 10 and 11 show a clip according to another example of the present invention.

Referring to Figures 10 and 11, the clip 70 made of biodegradable resin includes a disc-shaped base plate 71 and a center hole 81 formed in the base plate 71 into which the fixing string 60 is inserted. and a guide slot 83 formed in the base plate 71 to connect from the edge of the base plate 71 to the center hole 81.

The base plate 71 is formed in a disk shape. For example, the base plate 71 may be formed to have a diameter of 5 to 20 mm and a thickness of 0.5 to 3 mm.

The center hole 81 is formed in a circular shape. The center hole 81 is formed through the base plate 71. The diameter of the center hole 81 is larger than the diameter of the fixing line 60 and smaller than the diameter of the stopping protrusion 61.

The guide slot 83 is a passage through which the fixing line 60 moves to the center hole 81. Therefore, the fixing line 60 is moved through the guide slot 83 and inserted into the center hole 81. The guide slot 83 is formed to connect from the edge of the base plate 71 to the center hole 81.

The guide slot 83 is formed to gradually become narrower in width from the edge of the base plate 71 toward the center hole 81. The narrowest part of the guide slot (83) is the part where the guide slot (83) and the center hole (81) come into contact. The width of this part is smaller than the diameter of the fixing line 60.

The base plate 71 includes a center plate 72 having a center hole 81, a side plate 76 formed to surround the outside of the center plate 72 to be spaced apart from the center plate 72, and a center plate 72. ) and a connecting rib (78) connecting the side plate (76).

The center plate 72 includes a first part 73 with a center hole 81 formed in the center, and a second part 74 formed around the first part 73 and having a thinner thickness than the first part 73. ) is provided. The second part gradually becomes thinner as it progresses outward.

The side plate 76 is formed to have the same thickness as the first part 73 of the center plate 72.

The side plate 76 and the center plate 72 are connected by a connecting rib 78. In the illustrated example, three connecting ribs 78 are formed.

The connecting rib 78 is preferably formed to be thinner than the center plate 72 and the side plate 76 so that it can be disassembled earlier than the center plate 72 and the side plate 74. For example, the connecting rib 78 has the thinnest thickness of the second part 74, that is, the same as the outer edge thickness.

By forming the connecting rib 78 thin in this way, it can be adjusted so that the connecting rib 78 can be quickly disassembled.

A fin portion 87 is formed at the edge of the base plate 71. The fin portion 87 is formed to protrude from the edge of the base plate 71. Preferably, the fin portion 87 is formed to gradually protrude in a direction away from the entrance of the guide slot 83.

When inserting the fixing line 60 into the center hole 81 of the clip 70, it is easy to push the clip 70 with a finger due to the fin portion 87 protruding outward.

Of course, the above-described clip can be applied to the traps of Figures 3 and 9. Additionally, it can be applied to traps such as those shown in Figure 12.

Referring to Figure 12, the fixing line 90 is installed in the trap 10. The fixing line 90 is formed in a ring shape. The fixing line 90 is installed on the frame or net of the fish trap.

The main body and barricade 40 have the same structure as shown in FIG. 3. However, there is a difference in that a fixing hole 42 for fixing the clip 70 is formed on the upper part of the blocking plate 41 of the barricade 40. Additionally, a locking protrusion 55 is formed at the end of the control rope 50. The locking jaw 55 can be formed by tying the control rope 50 into a knot. When the control rope 50 is inserted into the center hole 81 of the clip 70, the locking jaw 55 is caught on the clip 70.

The left and right widths of the fixing holes 42 are slightly larger than the diameter of the base plate of the clip 70.

The control rope 50 is coupled to the net 30 by threading it around the left and right and upper and lower edges of the adult escape port 35. At this time, at the lower edge of the adult escape hatch, the control rope 50 is alternately moved in and out of the lower side ribs of the barricade 40 and is threaded into the mesh.
