Description
TECHNICAL FIELD
The présent invention relates to a fish trap.
B ACKGROUND ART
A fishing rod, a fishing net, a fish trap, etc. are generally used to catch fish living in the sea or river. Among them, the fish trap is advantageous in catching a greater amount of fish than a fishing rod adapted to catching individual fish while being more convenient to use than a fishing net.
Fish traps hâve various forms and configurations and hâve been disclosed by Korean Utility Model Publication No. 1993-0017507.
FIG. 1 shows an example of a spring fish trap among conventional fish traps, and FIGS. 2A to 2C show a method of collecting trapped fish from a fish trap.
As shown, a fish trap 10’ may include a frame 12p made of a cylindrical coil spring, and a fish trap mesh 1 lp surrounding the outer periphery of the frame 12p. The fish trap mesh is connected toward an inner center direction of the frame 12p to form entrances llap and llbp, and the entrances llap and llbp may further extend toward the inner center direction of the fish trap to form a luring part 13.
Fish 5 enter first luring parts 13aa and 13ba through entrances llap and llbp on both sides, and then passes lure frames 13a’ and 13b’, which support one end of the first luring parts 13aa and 13ba, respectively. After the fish passes through luring openings 13a” and 13b” of second luring parts 13ab and 13bb that are integrally connected to the first luring parts 13aa and 13ba at one end thereof and extend in a shape in which the diameter becomes narrower than that of the first luring parts 13aa and 13ba, the fish 5 canbe trapped in the fish trap 10’. The trapped fish 5 may be stored in a storage portion 14. A hait (not shown) may be disposed in the storage portion 14 to lure the fish 5. If fish trapping is completed, the fish 5 within the storage portion 14 are collected by shaking the fish trap 10’ on the ground. After the fish trap 10’ is pressed to be flattened, the fish trap 10’ is stored by fixing the opposing sides of the frame 12p of the fish trap 10’ by a fish trap fixing portion 15.
In the conventional fish trap 10’ above, the fish 5 stored in the storage portion 14 may easily escape through the luring parts. That is, when the fish 5 approach the vicinity of the luring openings 13 a” and 13b” while going around the storage portion 14, the fish 5 may easily escape to the outside. This is problematic in that the trapped amount of the fish 5 is reduced. Another problem is that foreign matters, such as wastes, jellyfish, etc., may flow in through the entrances 11 ap and 11 bp of the conventional fish trap 10’. If wastes or waste vinyls flow into the trap 10’, they may decay within the storage portion 14 to generate bad odor and the like, thereby making it difficult to trap the fish 5 by a bait. Further, the trapped fish 5 may die due to the wastes, thereby losing merchantable quality. Furthermore, if a jellyfish flows in, the jellyfish may eat the trapped fish 5, thus reducing the amount of the trapped fish.

FIG. 3 shows an example of a cylindrical fish trap according to one embodiment.
As shown, a fish trap may include a fish trap mesh 10, a frame 20, a luring part 30, and an escape prévention part 100.
The fish trap mesh 10 may be provided in a net shape. According to this embodiment, the fish trap mesh 10 may be supported by the frame 20 to form an internai space portion. For example, as shown in FIG. 3, the ends of the fish trap mesh 10 may be connected to a ringshaped frame 20 to form a cylindrical fish trap, thereby forming a space portion in which fish 1 can be trapped. The fish trap mesh 10 may be formed with an entrance 11 and an luring opening 12. The fish 1 flows in through the entrance 11. The fish 1 flows into the internai space portion after passing through the entrance 11. At this time, the luring opening 12 may be tied and fixed to the top side and the bottom side of the fish trap mesh 10 using a string member S for position fixing. This will be described again below.
The frame 20 may include first and second ring-shaped fiâmes 21 and 22. The frame 20 may be formed of a metallic material, and may be coated with a resin material in order to prevent corrosion or the like. Alternatively, the frame may be formed of various materials, such as a synthetic resin, instead of a metallic material.
Further, the first and second fiâmes 21 and 22 may be provided in ring shapes having a same diameter as shown in FIG. 3, or may be provided in a rectangular shape as shown in FIG. 4. As shown in FIG. 5, the first and second fiâmes 21 and 22 may hâve different diameters. The shapes of the fiâmes may be changed variously depending upon usage environments of the fish trap. Since the frame 20 is coupled to the fish trap mesh 10 to form a framework of the fish trap, the frame 20 may be changed into various shapes as necessary. Accordingly, the shapes of the first and second fiâmes 21 and 22 can be changed to various shapes, such as a circular shape, a triangular shape, a rectangular shape, a polygonal shape, etc.
The luring part 30 may be formed to extend from the entrance 11 of the fish trap mesh 10 in a direction toward the inside of the frame 20, and may include the luring opening 12. As shown in FIGS. 3 to 5, one luring part 30 may be formed on one side wall, but the location of the luring part is not limited thereto. That is, as shown in FIG. 6, a pair of luring parts 30a and 30b may be disposed opposite to each other, and, as shown in FIG. 7, a plurality of luring parts 30a, 30b, and 30c may also be provided. The number of the luring parts 30 may vary depending on the size of the fish trap, and may also be determined depending on the size of fish to be trapped.
As shown in FIG. 3, the luring part 30 may be connected to the entrance 11 formed in one side wall of the fish trap mesh 10, and the luring opening 12 may be configured with a diameter that is smaller than that of the entrance 11 and may be formed to narrow gradually. The fish 1 can be lured to the inside of the fish trap through the luring part 30.
This embodiment is characterized in that the escape prévention part 100 is provided inside the fish trap so as to prevent the already-trapped fish 1 from escaping to the outside of the trap.
The escape prévention part 100 may form an isolated space, and may be provided with at least one fish passage hole 110 and an outlet 120. The fish 1, which has passed through the luring opening 12 of at least one luring part 30 configured as described above, passes through the fish passage hole 110.
By way of example, as shown in FIG. 3, the escape prévention part 100 may be spaced apart from the luring part 30 by a predetermined distance g. At this time, since the distance g is formed to be smaller than the size of the fish 1, the fish that has passed through the luring opening 12 does not escape through such a gap. Even if the fish 1 were to escape, it is not a problem because the fish 1 is inside the fish trap. As shown, the fish 1, which has flowed in through the luring part 30, may pass through the luring opening 12 and then flow into the internai space portion of the escape prévention part 100 through the fish passage hole 110, and therefore may be received in the inside of the fish trap through the outlet 120.
Further, the escape prévention part may hâve various shapes. The escape prévention part 100 may be provided in a substantially cylindrical shape as shown in FIG. 3. As shown in FIG. 3, a pair of ring-shaped fiâmes is provided with a mesh formed on the fiâmes, and the fish passage hole 110 is formed in a side wall with an outlet 120 formed in any one of the top and bottom sides. At this time, the escape prévention part 100 may be tied with and assembled to the fish trap mesh 10 by using at least one string member S, a bar, or the like. As shown in FIGS. 3 and 4, the escape prévention part 100 may be installed by erecting it upright in a direction perpendicular to the fish travel direction of the luring part 30. As shown in FIG. 5, the escape prévention part 100 may be placed to be horizontal to the ground surface, but perpendicular to the fish travel direction. The position where the escape prévention part 100 is disposed may be changed variously depending on the structure and design of the fish trap.
FIG. 6 shows an example in which a pair of luring parts 30a and 30b is provided in the cylindrical fish trap according to an embodiment. In this example, the luring parts 30a and 30b may be provided with a first entrance lia and a first luring openings 12a, respectively, and a second outlet 11b and a second luring opening 12b, respectively. The first entrance and the second entrance may hâve the same shape and be disposed symmetrically, and the first luring opening and the second luring opening may hâve the same shape and be disposed symmetrically, but they are not limited thereto, and, if necessary, may be disposed at various positions.
Further, the escape prévention part 100 may be disposed to entirely surround a portion of one of the pair of luring parts 30a and 30b to a portion of the other of the pair of luring parts 30a and 30b. That is, as shown in FIG. 6, the first and second luring openings 12a and 12b are disposed opposite to each other, and the first and second luring openings 12a and 12b may be connected to each other by a string member S to be fixed in position. The escape prévention part 100 may be formed by surrounding the periphery of the first and second luring openings 12a and 12b with a mesh member. At this time, the outlets 120 of the escape prévention part 100 may be disposed at positions perpendicular to the first and second luring openings 12a and 12b. In addition, at least one outlet 120 may be formed.
That is, as shown in FIG. 7, a plurality of luring parts 30a, 30b, and 30c may be formed in the fish trap, and each of the luring parts 30a, 30b, and 30c may be provided with the escape prévention parts 100a, 100b, and 100c configured as described above.
On the other hand, as shown in FIG. 8, the escape prévention part 100 may be installed such that the luring opening 12 of the luring part 30 is disposed inside the escape prévention part. In this case, instead of the above-described fish passage hole 110 (see e.g., FIG. 3), the luring opening 12 may be directly inserted into the side wall of the escape prévention part 100 to be disposed in the internai space of the escape prévention part 100.
Further, as shown in FIG. 9, one luring part 30 may be provided, and the escape prévention part 100 having a spherical shape may hâve a plurality of outlets 120a, 120b, and 120c. On the other hand, as shown in FIGS. 10 and 11, a plurality of luring parts 30a, 30b, and 30c may be provided, and, similar to the embodiment of FIG. 8, the ends of the luring parts 30a, 30b, and 30c may be directly disposed in the internai space portion of the escape prévention part 100. In this case, it is also possible to form only one outlet 120 of the escape prévention part 100 and to dispose the outlet 120 to face the bottom side. At this time, the first and second trames 21 and 22 may hâve a circular shape or may hâve a polygonal shape. In addition, as shown, the second trame 22 may be formed to be larger than the first frame 21 so that the bottom side of the fish trap naturally faces downward when the fish trap is thrown into water. By forming the second frame 22 to hâve a larger size as described above, the bottom side may easily face downward in the water due to its own weight, and may not be easily tumed upside down by a stream of water.
According to such a configuration, the escape prévention part 100 inhibits the trapped fish 1 from entering the luring opening 12, which is the only place where the trapped fish 1 can escape from inside of the fish trap. In particular, the outlet 120 of the escape prévention part 100 and the fish passage hole 110 are formed to be perpendicular to each other. Thus, it is not easy for the fish 1 having poor eyesight to accurately proceed to the luring opening 12 through the outlet 120 and the fish passage hole 110. Therefore, it is possible to prevent fish from escaping through the luring opening 12 once the fish has been trapped.
FIGS. 12 to 20 show an example of a spring fish trap.
As shown, the spring fish trap may include a fish trap mesh 10, a plurality of frames 20, and a pair of luring parts 30a and 30b disposed to be opposite to each other on the frames 20. The frame 20 may include first to fourth frames 21 to 24 and a coil frame 25.
The first and second frames 21 and 22 may be disposed opposite to each other. The third and fourth frames 23 and 24 may be disposed opposite to each other between the first and second frames 21 and 22 in a state of being spaced apart from each other by a predetermined distance. On the other hand, the coil frame 25 may be coupled to the first frame 21 at one end and may be coupled to the second frame 22 at the opposite end, thus spacing the first and second frames 21 and 22 apart from each other by a predetermined distance.
Further, the diameters of the first and second frames 21 and 22 may be larger than the diameters of the third and fourth frames 23 and 24 such that the luring parts 30a and 30b may be formed to narrow gradually toward the inside of the fish trap.
According to this embodiment, the fish trap is characterized in that the escape prévention part 100 is provided such that the fish 1 cannot escape once the fish flows into the inside of the fish trap. The escape prévention part 100 is coupled in various ways as shown in FIGS. 12 to 20.
That is, as shown in FIG. 12, the fish, which has passed through the luring opening 12a formed at an end or a bottom side of the luring part 30a, flows into the internai space of the escape prévention part 100, and may then be received in the internai space of the fish trap mesh 10 through the outlet 120. At this time, since the escape prévention part 100 is formed to surround a portion of the luring part 30a of the fish trap into which the fish flows, the fish cannot easily escape from a place where the fish has entered the fish trap.
FIGS. 13 to 20 show other examples in which the size of the escape prévention part 100 is adjusted such that the escape prévention part 100 includes a portion of the luring part 30a. In this case, the fish, which has passed the luring openings 12a and 12b, can flow into the inside of the fish trap through the outlets 120 and 120’, respectively, and the escape prévention part 100 can prevent the lured fish from escaping through the entrances lia and 11b.
Further, as shown in FIGS. 20 and 21, the first luring part 30a is connected to the first frame 21 at one end and is connected to the third frame 23 at an opposite end. The second luring part 30b is connected to the second frame 22 at one end and is connected to the fourth frame 24 at an opposite end.
At this time, the frame 20 may be configured with the first to fourth frames 21 to 24 and the coil frame 25. The fish trap mesh 10 may include: a fish trap mesh 10a coupled to the frame 20 to form the exterior of the fish trap; a second fish trap mesh 10b coupled to the first frame 21 at one end and coupled to the third frame 23 at an opposite end; a third fish trap mesh 10c coupled to the second frame 22 at one end and coupled to the fourth frame 24 at an opposite end; and fourth and fifth fish trap meshes lOd and 10e, each of which has a luring opening 12, through which the fish 1 passes, at an end. The fourth trap mesh lOd may be formed integrally with the fifth fish trap mesh 10e. In this case, the fourth trap mesh may be connected to the third frame 23 at one end and connected to the fourth frame 24 at an opposite end. Further, the fourth fish trap mesh may hâve a eut portion at a vicinity of a center portion such that a fish entrance (i.e., the luring opening 12) in close contact with the eut portion is formed when the fish trap is unfolded.
In this case, a portion of each of the first and second luring parts 30a and 30b, which include first and second entrances lia and 11b, respectively, may be surrounded by the escape prévention part 100. To this end, the third and fourth frames 23 and 24 may be disposed in the inner région of the escape prévention part 100. That is, one end of the escape prévention part 100 may be connected to the second fish trap mesh 10b and the opposite end of the escape prévention part 100 may be connected to the third fish trap mesh 10c, thereby surrounding a portion of each of the second and third fish trap meshes 10b and 10c and the entire périphéries of the fourth and fifth fish trap meshes lOd and 10e.
Further, as shown in FIGS. 21 and 22, in one embodiment, the escape prévention part 100 may further include fifth and sixth fiâmes 101 and 102 in order to prevent fish from escaping from the fish trap. One end of the escape prévention part 100 is coupled to the fifth frame 101, and the opposite end of the escape prévention part 100 is coupled to the sixth frame 102. The fifth frame 101 and the sixth frame 102 may be provided substantially in a ring shape. The second fish trap mesh 10b and the fifth frame 101 may be coupled to each other, and the third frame 10c and the sixth frame 102 may be coupled to each other. The fifth and sixth frames 101 and 102 may hâve a width that is smaller than that of the first and second frames 21 and 22 and that is greater than or equal to that of the third and fourth frames 23 and 24, and may be disposed opposite to each other. Accordingly, both the first and second luring openings 12a and 12b may be disposed in the internai space portion of the escape prévention part 100, and the fish, which has passed through the first and second luring openings, can be received in the inside of the fish trap through the outlet 120.
Further, a plurality of outlets 120a, 120b, and 120c may be formed through the escape prévention part 100. The arrangements of the plurality of outlets may be varied as shown in FIGS. 23A to 23C. The outlet 120 may hâve various shapes, such as a circular shape, an oval shape, a polygonal shape, and the like. At least three or more outlets 120 may be formed through the escape prévention fish trap mesh, which forms the escape prévention part 100.
That is, as shown in FIG. 23 A, the outlets 120 may be disposed such that a virtual extension line connecting respective centers is parallel with a virtual extension line that passes through the center of the escape prévention part 100. Alternatively, as shown in FIG. 23B, the outlets 120’ may be disposed such that a virtual extension line connecting respective centers forms a predetermined angle with the virtual extension line that passes through the center of the escape prévention part 100’. Alternatively, it is also possible to provide four outlets 120” as shown in FIG. 23C and to arrange the outlets 120” as shown in FIG. 23 A.
FIGS. 24Ato 24C show a configuration in which a foreign matter prévention unit 600 is installed in the spring fish trap among the fish traps according to one embodiment. Since a pair of the foreign matter prévention units 600 having the same structure is coupled to the first and second fiâmes 21 and 22 respectively, only one foreign matter prévention unit 600 may be described by way of an example.
The foreign matter prévention unit 600 may be connected to the foreign matter prévention frame 610 by a plurality of string members 620, and may be coupled to a foreign matter prévention fish trap mesh 615 to form a blocking partition. At this time, the foreign matter prévention frame 610 is smaller than the first frame 21. As shown in FIGS. 24B and 24C, a hait bag b may be provided at an end of the foreign matter prévention mesh. The hait bag b may be formed by tying a portion of the foreign matter prévention fish trap mesh by means of, for example, a string 630. At this time, the string 630 may be formed with a knot 635 by using a string for tightening an onion net or the like. According to the above-described configuration, the fish can flow into the fish trap together with water through a space portion adjacent to and around the foreign matter prévention unit 600, and wastes or foreign matters can be blocked by the foreign matter prévention unit 600, thus preventing the wastes or foreignmatters from flowing into the inside through the entrance lia.
Further, FIGS. 24A to 24C show a configuration in which the foreign matter prévention frame 610 is supported by a total of four string members 620. However, the number of connection members such as the string member 620, a bar, or the like may be changed if necessary without being limited thereto. In addition, the foreign matter prévention unit 600 may be configured to be positioned at the center or at a location offset to one side.
Further, as shown in FIGS. 25 to 30, the fish trap may further include at least one partitioning fish trap mesh 400, which is spaced apart from the outlet 120 by a predetermined distance and which is disposed between the outlet 120 and the fish trap mesh coupled to the frame 20 to divide the internai space of the fish trap.
As shown, the partitioning fish trap mesh 400 may include a fish storage portion 410 and a partition 420.
The fish storage portion 410 may include first to third fish storage portions 411, 413, and 415, each of which may store the fish 1 of a different size.
The partition 420 is provided such that fish of different sizes are separately received inside the fish storage portion 410, and may include first to third partitioning fish trap meshes 421, 423, and 425. Additionally, as shown in FIGS. 25 and 26, the first and second partitioning fish trap meshes 421 and 423 may be provided with first and second fish passage holes 411a and 413a, respectively. At this time, the first fish passage hole 411a may be formed to be larger than the second fish passage hole 413 a. According to such a configuration, small fish among the fish that hâve passed the outlet 120 can escape to the third fish storage portion 415 formed at the outermost side. Thus, it is possible to prevent big fish from eating the small fish within the fish trap, thereby preventing réduction in the amount of fish that hâve been caught.
In addition, as shown in FIG. 27, first and second division partitions 416 and 418 dividing an internai space may be formed in the second and third fish storage portions 413 and 415, respectively. Further, as shown, the first and second partitioning fish trap meshes 421 and 423 may be provided with a plurality of the first fish passage holes 411a and a plurality of the second fish passage holes 413 a, respectively.
The first and second division partitions 416 and 418 may be formed to be larger than the first and second passage holes 416a and 418a, respectively, through which the trapped fish passes. Further, as shown in FIG. 28, division partitions 412 and 414 may be formed in the fish storage portions 411,413, and 415 in a direction parallel to a longitudinal direction of the fish trap, and first and second passage holes 412a and 414a may be formed in the division partitions 412 and 414, respectively. The sizes of the first and second passage holes 412a and 414a may be different from each other. For example, the size of the first passage hole 412a may be larger than that of the second passage hole 414a.
Further, as shown in FIG. 28, the first partitioning fish trap mesh 421 may be formed with a first fish guide passage hole 411b. The first guide passage hole 41 lb includes first and second guide passage holes 411ba and 411bb with the division partition 412 located therebetween. The second partitioning fish trap mesh 423 may be formed with a second fish guide passage hole 413b. The second fish guide passage hole 413b includes third and fourth guide passage holes 413ba and 413bb with the division partition 414 located therebetween. The size of the second fish guide passage hole 413b may be smaller than that of the first fish guide passage hole 41 lb in order to allow smaller fish to be stored toward the outermost side.
FIG. 29 shows a configuration in which a blocking partition 500 is formed in a direction peipendicular to the longitudinal direction of the above-described fish trap and first and second passage holes 416a and 418a of circular shapes are formed in different sizes through the first and second division partitions 416 and 418, respectively. The first passage holes 416a may be formed to be larger than the second passage holes 418a. In addition, a first fish guide passage hole 411c may be formed in the first partitioning fish trap mesh 421, and a second fish guide passage hole 413c may be formed in the second partitioning fish trap mesh 423. The first fish guide passage hole 411c and the second fish guide passage hole 413c may be configured to hâve different sizes such that only small fish can move outwardly.
FIG. 30 shows a state where fish la and fish lb having different sizes are separately accommodated.
As shown, the first fish guide passage hole 411b may be formed in the first partitioning fish trap mesh 421. The first fish guide passage hole 41 lb may be configured with first and second guide passage holes 411ba and 411bb having different sizes, so that fish canbe separately disposed with the blocking partition 412’ being interposed therebetween. In addition, a through hole 412a having a first diameter may be formed in the blocking partition 412’ so that relatively small fish lb can pass through the through hole 412a and relatively big fish la cannot pass through the throughhole 412a.
Further, the second fish guide passage hole 413b may be formed in the second partitioning fish trap mesh 423. The second fish guide passage hole 413b may be configured with third and fourth guide passage holes 413ba and 413bb having different sizes, so that fish can be separately disposed with the blocking partition 414’ being interposed therebetween. In addition, a through hole 414a having a second diameter may be formed in the blocking partition 414’ so that relatively small fish ld can pass through the through hole 414a and relatively big fish 1 c cannot pass through the through hole 414a.
FIG. 31 schematically shows a configuration in which a door unit 700 is installed in a spring fish trap according to one embodiment. Since other configurations are the same as those described above, a redundant description will be omitted.
The door unit 700 may be installed at one end of the luring part 30b, and one end of the door unit 700 may be connected to a string member 750 such that the door unit 700 may be opened along with the contraction movement of the spring fish trap. The string member 750 can be hooked and fixed to a hook 760 which is formed in the first frame 21 and is located in the diagonal direction of a release prévention ring 770 through the release prévention ring 770. When the hook 760 is released from engagement with the first frame, the string member 750 coupled to the hook 760 may lose its tension such that a door portion 720 may be in an openable and closable state. Further, the release prévention ring 770 is not necessarily required. It is also possible that the string member 750 may be configured to be wound such that one end of the string member 750 is fixed to the first frame 21 or the third frame 23.
FIGS. 32Ato 32D is a view specifically show the door unit 700 according to such an embodiment.
As shown, the door unit 700 may be divided into a frame portion 710 and a door portion 720. At least a pair of fixing portions 711 and 712 may be provided in the frame portion 710, and the frame portion 710 may be fixed to both ends of the frame 20. Additionally, a fish discharge hole 713, which allows the door portion 720 to be opened/closed, may be formed in the vicinity of the center portion of the frame portion 710, and a locking device (or referred to as a locker) 717 may be installed to maintain the closed state of the door portion 720. The frame portion 710 may be provided with a hinge portion 715 such that the door portion 720 can be rotatably opened/closed.
The door portion 720 may include a door trame 721, which forms a periphery and has the fish discharge hole 713 at a center portion, and a door mesh 725 coupled to the door trame 721. In addition, the string member 750 may be connected to the inside of the fish trap at one end ofthe door portion 720, preferably at a side opposite the hinge portion 715. Further, as shown, the above-described door unit 700 may be formed with a mesh structure 719 as a whole so that water can pass therethrough.
As shown in FIGS. 33 A and 33B, in the door unit 700 according to this embodiment, the above-described fixing part 712 may be coupled to the fourth frame 24. Accordingly, the door unit 700 can selectively open and close the entire internai space portion of the fish trap. That is, one end of the string member 750 is coupled to the door portion 720 and the opposite end is connected to the first frame 21 as described above. Thus, if the fish trap is contracted by applying a force F in a direction indicated by arrows as shown in FIGS. 34A and 34B, the door portion 720 is in an openable state shown in FIG. 34B due to the release of the pulling force of the string member 750. Accordingly, the trapped fish 1 can be collected through the door unit 700.
Further, as shown in FIG. 35, when the fish trap is provided with a plurality of fish storage portions, auxiliary door units for the respective fish storage portions 411, 413, and 415 may be individually installed inside the door unit 700.
That is, as shown in FIGS. 35 and 36A to 36C, the fish trap according to this embodiment may further include, inside the door unit 700, an auxiliary door unit 730 configured to open and close the first to third fish storage portions 411, 413, and 415, and a door portion 720 having the above-described configuration may be installed on the auxiliary door unit 730 so as to be pivotally opened/closed.
In FIGS. 36A to 36C, the auxiliary door unit 730 may be configured to include first to third auxiliary door units 730a, 730b, and 730c, and an auxiliary hinge portion 745 including first to third auxiliary hinge portions 745a, 745b, and 745c may be provided so as to allow the first to third auxiliary door units 730a, 730b, and 730c, respectively, to be pivotally openable and closable. The first auxiliary door unit 730a includes a first door frame 731a having a first fish discharge hole at a central portion thereof, a first door member 735a installed in the first door frame 731a so as to be openable and closable, and a first locker 737a configured to regulate an opening/closing operation of the first door frame 731a and the first door member 735a. The second auxiliary door unit 730b includes a second door frame 73 lb having a second fish discharge hole at a central portion thereof, a second door member 735b installed in the second door frame 731b so as to be openable and closable, and a second locker 737b configured to regulate an opening/closing operation of the second door frame 731b and the second door member 735b. The third auxiliary door unit 730c includes a third door frame 731c having a third fish discharge hole at a central portion thereof, a third door member 735c installed in the third door frame 73le so as to be openable and closable, and a third locker 737c configured to regulate an opening/closing operation of the third door frame 731c and the third door member 735c. Further, each of the first to third auxiliary door units 730a, 730b and 730c is provided with an auxiliary string member 757 (i.e., first to third auxiliary string members 757a, 757b and 757c) such that the first to third auxiliary door units 730a, 730b, 730c may be opened in response to a contraction movement of the spring fish trap. Further, the auxiliary door units 730 may also be provided with first to third locking devices 737a, 737b, and 737c, respectively, so as to maintain the closed state. The locking devices 737a, 737b, and 737c may hâve the same configuration as the above-described locking device 717. The locking devices described above may be provided as a lever type. Additionally, when the outermost door portion 720 is not opened, the auxiliary door units 730 are not opened. Thus, even if the first to third locking devices 737a, 737b, and 737c are opened, the fish do not corne out.
According to such configurations, the trapped fish 1 can be easily collected through the opening/closing of the door portion in comparison to conventional devices. That is, fish are sorted and trapped depending on different sizes. Thus, if the auxiliary door units 730 are selectively opened according to the size of the fish to be collected, the fish of one size can be collected at a time. Thus, it is possible to reduce the time required for the sorting work after the collection.
As variations of the above-described embodiments, FIG. 37 shows a configuration in which a partition for separately trapping fish of different sizes is additionally provided in a truncated conical fish trap.
As shown, the first to third partitioning fish trap meshes 421, 423, and 425 may be further installed in the fish trap having a pair of entrances lia and 11b. Further, as described above, the first and second partitioning fish trap meshes 421 and 423 may be formed with fish passage holes of different sizes. Accordingly, fish of different sizes can be stored in the first to third fish storage portions 411, 413, and 415, respectively.
FIG. 38 shows a fish trap of a truncated conical shape to which the above-described door unit 700 is applied. The basic configuration and operation of the door unit 700 are the same as those described above. However, when the door unit 700 is opened through an action of releasing the hooking of the string member, the collection of fish trapped inside the fish trap is further simplified.
FIG. 39 shows a configuration in which the foreign matter prévention unit 600 is installed at the first and second luring parts 30a and 30b in a fish trap of a polygonal column shape.
The configuration and effect are the same as those described above.
