Description

[Technical field]

[0001] The present invention relates to a leg-binding type animal trap for capturing wild animals such as deer and boar. [Background technology]

[0002] Regarding animal traps, for example, Patent Documents 1 and 2 are disclosed, and the configuration of each claim 1 and the configuration of the embodiment level are explained below using the terms and symbols used in each document.

[0003] The animal trap 1 disclosed in Patent Document 1 comprises a mounting base 3, a footboard assembly 2 placed on the mounting base 3, and a capture wire rope 70 having a tip portion 72 wound around rope hanging arms 5A, 5B of the footboard assembly 2.

[0004] In this animal trap 1, the mounting base 3 has a long rectangular bottom plate portion 31 having a drainage hole, and four side plate portions 32-35 extending upward from the four edges of the bottom plate portion 31 and forming a drop-in space. The footplate assembly 2 has a footplate 4 that can be stored within the mounting base 3 so as to be close to the inside of the four edges of the mounting base 3, two hinge ribs that rise from both side edges of the footplate 4 to a required inner side, and two rope hanging arms 5A, 5B whose upper ends of straight sections on both sides are continuous with both ends of an arch section having a groove-shaped recess on the outside in the middle, and whose lower ends are pivotally attached to the two hinge ribs and are provided on the upper surface of the footplate 4 so as to be freely raised and lowered toward the long side. The capture wire rope 70 has a tip washer portion 72 formed at the tip of the wire rope main body 31, and a wire rope main body tension spring 73 that reduces the diameter of the tip washer portion 72 and applies a diameter-reducing force.

[0005] With the two rope hanging arms 5A, 5B open on both sides and fallen down in a mountain shape, and with the tip washer portion 72 wrapped around the outer periphery of the rope hanging arms 5A, 5B applying a diameter-contracting force, the two rope hanging arms 5A, 5B are placed on the two side plate portions on the short edge side of the bottom plate portion 31 of the mounting platform 3, and with the four edges of the foot plate 4 close to the inside of the four side plate portions of the mounting platform 3, the foot plate 4 is maintained in a floating state in the drop-down space of the mounting platform 3.When the feet of a captured animal step on the foot plate 4 and the rope hanging arms 5A, 5B rotate upward, the tip washer portion 72 comes out upward from the rope hanging arms 5A, 5B and contracts in diameter to capture the feet of the captured animal.

[0006] Additionally, Patent Document 2 discloses a trap for capturing animals.

[0007] The Kobayashi-style bait-and-trap method is recommended for setting animal traps in all cases. In this method, the trapping point is set by feeding the animals with hay cubes or rice bran. The trap is set in a location where feeding conditions are good. The conditions for setting the trap are such that the animal's feet step on the footplate and the tip of the trap is narrowed, preventing the trap from catching the animal's feet and allowing the animal to escape (called an "empty flick"). Specifically, obstacles (pebbles found in the area) that the captured animal does not want to place its feet on are placed around the trap, and the trap is then fed with hay cubes or rice bran. This is said to encourage the captured animal to avoid the obstacles and place its feet on the footplate when eating the food, thereby increasing the probability of capture. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Utility Model Registration No. 3165447 [Patent Document 2] Patent No. 6656525 Summary of the Invention [Problem to be solved by the invention]

[0009] However, in both of the animal traps disclosed in Patent Documents 1 and 2, for the reasons described below, when a wild animal such as a deer or boar steps on the footplate, the tip of the trap is often activated to narrow the trap head, resulting in a "blank splash," or the trap head may not be able to narrow the trap head, resulting in a low capture rate.

[0010] In the animal trap disclosed in Patent Document 1, when a wild animal such as a deer or boar steps on both ends of the bent parts of the two steps 4A and 4B, the joints 5, or the parts near the joints 5 of the guide flange plate 9, the steps 4A and 4B are bent in a valley, and the tip washer 52 is pushed upward from the outer periphery of the steps 4A and 4B by the force of the wire rope body tension spring 53 and is squeezed, but it is an "empty kick" and the feet of the captured animal cannot be caught. Also, when an animal trap is set using the Kobayashi-type attraction and capture method, if the stones (obstacles) arranged around the trap are misaligned and stick to the steps 4A and 4B, causing lateral pressure, the steps 4A and 4B will not be bent in a valley even if the wild animal such as a deer or boar places its feet on the steps 4A and 4B, or the lifting will be delayed and the tip washer 52 will be slow to come off the outer periphery of the steps 4A and 4B, which the wild animal will sense as an abnormality and quickly remove its feet, resulting in an "empty kick" and making it impossible to catch the feet of the captured animal.

[0011] In the animal trap disclosed in Patent Document 2, when a wild animal such as a deer or boar steps on the upper part of the support shaft 50 of the rope hanging arms 5A, 5B, the footboard 4 drops and at the same time the two rope hanging arms 5A, 5B, which are maintained in a mountain shape, jump up, and the tip washer 72 escapes upward from the outer periphery of the rope hanging arms 5A, 5B and is narrowed. However, because the wild animal's feet are not positioned inside the rope hanging arms 5A, 5B, the narrowed tip washer 72 does not reliably capture the feet of the captured animal, and there is a high probability that it will be an "empty hit." In the embodiment of the animal trap shown in Figure 7, the arc-shaped connecting parts 52, 52 of the rope hanging arms 5A, 5B protrude significantly outward from the side panels 32, 33 of the mounting base 3, so that when a wild animal's foot steps near the center of the connecting part 52, the tip washer part 72 does not come off the outer periphery of the rope hanging arms 5A, 5B, and the opposite side rises up. This is sensed by the wild animal as something abnormal, and the wild animal quickly removes its foot, resulting in an "air flick" and making it impossible to capture the foot of the animal to be trapped.

[0012] In addition, when setting an animal trap using the Kobayashi-style luring and capturing method, if the stones (obstacles) arranged around the trap are displaced and come into close contact with the connecting parts 52 of the rope hanging arms 5A and 5B, even if a wild animal such as a deer or boar steps on the inside of the rope hanging arms 5A and 5B of the footboard 4, the rope hanging arms 5A and 5B will not jump up and join together, which also results in an "empty bounce" and the feet of the captured animal cannot be caught. Furthermore, even if you try to prevent wild animals from discovering the existence of the connecting parts 52 by placing dead leaves on the footboard 4 and covering it with soil, the soil will be washed away by wind and rain and accumulate inside the mounting base 3, causing a problem that the footboard 4 cannot fall down. Furthermore, it is difficult to prevent wild animals from discovering the existence of the connecting parts 52 by placing dead leaves on the connecting parts 52 and covering them with soil, and when the leaves and soil are washed away by wind and rain, the connecting parts 52 will be exposed, and the shape of the connecting parts 52 will be sensed by wild animals, allowing them to discover the existence of the animal trap.

[0013] The animal trap disclosed in Patent Document 2 is accommodated in a mounting base 3 having four side panels 32a-32d with the upper ends thereof extending at the same height, with the rope hook arms 151, 151 maintained in a mountain shape and the tip washer 72 wound around the outer periphery, and the rope hook arms 151, 151 are configured to be lower than the upper ends of the four side panels 32a-32d. Therefore, when setting up an animal trap using the Kobayashi-type attraction and capture method, a recess is provided to accommodate the mounting base 3 so that the upper ends of the four side panels 32a-32d are approximately at the same level as the surrounding soil surface, and not only is soil covered over the rope hook arms 151, 151, but soil is also provided to cover the upper ends of the four side panels 32a-32d of the mounting base 3. It is necessary to cover the trap with soil, which requires a large amount of soil. Therefore, when the trap is exposed to wind and rain after being set, a large amount of soil will flow into the mounting table 3, and the space below one of the steps 4 may become filled with the soil. As a result, even if a wild animal steps on the step 4, it is difficult for the step 4 to fall smoothly, and the rope hanging arms 151, 151 will not jump up with sufficient force, resulting in a time lag between the wild animal stepping on the step 4 and the tip washer narrowing. During this momentary time lag, the wild animal will avoid its foot that is stepping on the step 4, and even if the tip washer narrows, it will fail to capture the foot of the captured animal.

[0014] In both of the animal capture traps disclosed in Patent Documents 1 and 2, the capture wire rope 30 enters the inside of the mounting base 3 through a large opening in the middle of the long side of the mounting base 3, and the tip washer is deployed into a long rectangle, so soil gets inside the mounting base 3 through the opening, and as a result, even if a wild animal steps on the footboard 4, the footboard 4 does not fall smoothly, resulting in a failure to capture the foot of the captured animal. Furthermore, the base end of the tip washer is open 180 degrees, and sometimes the bending resistance of the wire rope causes a delay in the narrowing of the tip washer, resulting in a failure to capture the foot of the captured animal.

[0015] The present invention is an improvement based on the technology of Patent Document 1 mentioned above in order to eliminate the above-mentioned problems, and due to the combined structure of the mounting base and footplate assembly, it is easy to cover the side panels of the mounting base and the rope hanging arm with a small amount of soil to prevent wild animals from finding it, and wild animals are less likely to step on the rope hanging arm, so the tip washer does not become an "empty flick." Furthermore, it is possible to provide an animal trap which has the following improvements: the delay in narrowing the tip washer due to the bending resistance of the wire rope at the boundary between the wire rope main body and the tip washer is eliminated, thereby reducing "empty flicks." [Means for solving the problem]

[0016] The animal trap of the first aspect of the present invention comprises a mounting base, a footplate assembly placed on the mounting base, and a capture wire rope having a tip portion wound around a rope hanging arm of the footplate assembly.

[0017] The basic components of the animal trap according to the first aspect of the present invention are: The mounting table has a rectangular bottom plate portion and four side plate portions extending upward from four edges of the bottom plate portion, The step plate assembly comprises a step plate that can be accommodated in the stand so as to be adjacent to the inside of the four side plate portions, two hinge ribs that rise from both side edges of the step plate to a required inner side, and two rope hanging arms that are pivotally attached to the two hinge ribs and are provided so as to be freely raised and lowered in the long side direction of the step plate and can be switched between a state in which they are open in a mountain shape of 180 degrees or more and a state in which they are raised together, and each of the rope hanging arms has two parallel and straight leg portions whose one ends are pivotally attached to the hinge ribs, and an arch portion that integrally connects the other ends of the two leg portions together, The capture wire rope has the tip washer at the tip of the wire rope body, a wire rope tension spring that reduces the diameter of the tip washer and applies a diameter reduction force, and a fixing portion formed at the rear end of the wire rope body, The two rope hanging arms are open on both sides and laid down in a mountain shape, and the tip washer portion is wound around the outer periphery of the rope hanging arms to apply a radial contraction force. The two rope hanging arms are placed on the two side plate portions on the short side of the bottom plate portion, and the rectangular periphery of the footboard is maintained in a floating state in the drop-in space of the stand with the footboard close to the inside of the four side plate portions, In an animal trap, when the foot of a captured animal steps on the foot plate and the rope hooking arm rotates upward, the tip of the washer portion comes out upward from the rope hooking arm and is reduced in diameter to capture the foot of the captured animal,

[0018] The characteristic components of the animal trap according to the first aspect of the present invention are the following improvements on the placement base, the footboard assembly, and the capture wire rope: The mounting table is The two side plate sections on the short sides of the bottom plate section have a table section on which the arch sections of the rope hanging arms, which rise vertically from the bottom plate section and extend horizontally outward to form a mountain shape, are placed without protruding outward, and the two side plate sections on the long sides of the bottom plate section do not have an opening for introducing the rope hanging arms from the outside of the tip washer section to the inside, and are configured to rise in a mountain shape to the extent that the two rope hanging arms, which are placed on the table section and in a mountain shape when viewed from the outside, cannot be seen. The footboard assembly is The step plate is a rectangle having no elongated openings formed by cutting and bending the outer sides of the two hinge ribs to provide the hinge ribs, and is in close proximity to the inner sides of the four side plate portions; The two legs of the rope hanging arm extend to the corners of the long side of the footboard, and the arch portion is an arc shape that integrally connects the other ends of the two legs together, and when the rope hanging arm is in the mountain-shaped state, it is placed on the table portion by protruding outward in the long side direction of the footboard, The capture wire rope is The ring portion is positioned in the arch portion of the rope hanging arm on one of the table portions, and the wire rope main body and the wire rope tension spring extending outward from the ring portion, which is the loop base end of the tip washer portion, are passed over the table portion.

[0019] The animal trap according to the second aspect of the present invention has the same configuration as the first aspect of the invention, but is also configured such that the arch portion of the rope hanging arm, which is on the swinging side from the point where it abuts against the short edge of the footboard, is slightly bent so that almost the entire length of the lower end is in close contact with the table portion.

[0020] The animal trap according to the third aspect of the present invention has the same configuration as the first or second aspect of the invention, and in addition, the hinge rib is made of two angle-shaped members or one channel-shaped member formed by bending a plate material of the required shape that is separate from the footplate, and is overlapped on the footplate and fixed thereto by welding, bolting, or other fixing means.

[0021] The animal trap according to the fourth aspect of the invention of the present application has the same configuration as the third aspect of the invention, and in addition, the hinge rib rises in a mountain shape to the extent that the two rope hanging arms are not visible from the inside when they are placed on the table portion in a mountain-like position, and cooperates with the two side plate portions on the long sides of the bottom plate portion to cover the legs of the rope hanging arms so that the feet of a captured animal do not rest directly on them. Effect of the Invention

[0022] According to the present invention, an animal trap can be provided that is an improvement based on the technology of the above-mentioned Patent Document 1 and can improve the conventional problems. Specific improvements include: (1) in the past, when a wild animal stepped on the rope hooking arm, the rope hooking arm would jump up, the tip of the washer would shrink in diameter, and the trap would be "empty," but the side plate of the mounting base can prevent the rope hooking arm from jumping up; (2) in the past, the wire rope forming the tip of the washer at the ring part was open 180 degrees to the left and right, and the bending resistance of the wire rope was large, which caused the "empty trap" due to the delay in narrowing the tip of the washer; but the bending of the wire rope can be reduced and the resistance can be reduced, eliminating the delay in narrowing the tip of the washer and reducing the "empty trap"; and (3) in the past, a large gap had to be secured at the introduction part of the tip of the mounting base, and therefore the soil covering the side plate of the mounting base and the rope hooking arm to prevent the wild animal from finding it was hidden in the gap between the mounting base and the step plate. It is possible to provide an animal trap which achieves the improvements of (1)-(4) above, in contrast to the problem that a large amount of soil falls into the mounting base from the gap, and when rain falls and several days pass after the trap is set, soil flows into the mounting base through this gap and accumulates, making it impossible for the footboard to fall down, by covering the side panels and rope hooking arm of the mounting base with a small amount of soil, and (4) when setting an animal trap using the Kobayashi-type attracting and capturing method, the rope hooking arm does not become inoperable even if stones arranged around the mounting base are abutted against the mounting base, and instead the stones serve as a positioning means for the mounting base, and when the Kobayashi-type attracting and capturing method is applied, both sides of the rope hooking arm can be satisfactorily covered with soil, soil hiding the rope hooking arm etc. is prevented from flowing into the mounting base through the gap between the footboard and the mounting base and accumulating, and the footboard is prevented from falling down improperly due to the accumulated soil.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] An animal trap according to an embodiment of the present invention will now be described with reference to the drawings.

[0025] [Basic components] As shown in Figure 1, an animal trap 1 according to an embodiment of the present invention comprises a mounting base 10, a footplate assembly 20 placed on the mounting base 10, and a capture wire rope 30 having a tip portion 33 wound around the rope hanging arms 23, 23 of the footplate assembly 20.

[0026] The support platform 10 and the footplate assembly 20 are formed by sheet metal forming or press forming using, for example, an aluminum plate having a thickness of 0.9 to 3.2 mm, or an alloy thereof, or an iron plate, a tin plate, a stainless steel plate, or the like.

[0027] The mounting table 10 has a rectangular bottom plate 11 having a drainage hole 11a, and four side plate portions 12-15 that extend upward from the four edges of the bottom plate 11 and form a drop space. The size of the bottom plate 11 is, for example, 10×15 mm to 20×30 mm in width×length.

[0028] The step assembly 20 has a step 21, two hinge ribs 22, 22, and two rope hanging arms 23, 23.

[0029] The step plate 21 is sized so that it can be accommodated within the platform 10 so that it is close to the inside of the four side plate portions 12-15 with a gap of, for example, 1.5-3 mm around the perimeter. The step plate 21 has depending ribs 21d, 21d that extend downward from the underside of the short side edge. The depending ribs 21d, 21d have the function of abutting against the side plate portions 12, 14 to prevent the step plate 21 from shifting when a force acts on the step plate 21 to shift it in the longitudinal direction.

[0030] The two hinge ribs 22, 22 are positioned at a required inner side from both side edges of the step plate 21 and rise up integrally with the step plate 21.

[0031] The two rope hanging arms 23, 23 are pivotally attached to two hinge ribs 22, 22 and are provided so as to be freely raised and lowered in the long side direction of the step 21, switching between a state in which they are open in a mountain shape of 180 degrees or more and a state in which they are raised together. The state in which they are open in a mountain shape of 180 degrees or more refers to a state in which the two rope hanging arms 23, 23 are opened horizontally and the swing end side is lowered by, for example, 1-5 degrees. Because of this angle, when the tip washer part 33 is wound around the outer periphery of the two rope hanging arms 23, 23 and tightened, the lower parts of the two rope hanging arms 23, 23 abut against the short side edge of the step 21, and are maintained in a state in which they are open in a mountain shape of 180 degrees or more.

[0032] Each rope hanging arm 23 is formed by bending a strip of a required length, for example, 1.5-3.2 mm thick and 10-20 mm wide, into a U-shape, and has two parallel, straight leg parts 23a, 23a pivotally attached at one end to the hinge ribs 22, 22, and an arch part 23b integrally connecting the other ends of the two leg parts 23a, 23a. The outer surface of the arch part 23b is formed into a concave groove shape. The pivot part 24 between the rope hanging arm 23 and the hinge ribs 22, 22 may be, for example, a rivet, bolt, nut, etc. with a diameter of 6 mm.

[0033] The capture wire rope 30 has a wire rope body 31, a tip washer portion 33, a wire rope tension spring 34, and a fixing portion 35.

[0034] The tip washer portion 33 has a diameter that can be expanded or contracted by passing the tip portion connected to the ring portion 32 of the wire rope main body 31 through the ring portion 32, which is formed in a loop shape at the tip of the wire rope main body 31 with a diameter, for example, twice the rope diameter.

[0035] The wire rope tension spring 34 has a coil spring 34a of the required length, which is made of a small diameter coil covered by a large diameter coil, a tubular portion 34b integrally formed at the base end of the coil spring 34a, and a wing bolt 34c screwed into the tubular portion 34b. The wire rope body 31 is inserted through the coil spring 34a and the tubular portion 34b, and by compressing the length of the coil spring 34a in the direction of the tip washer portion 33 and tightening the wing bolt 34c to the wire rope body 31, the tip washer portion 33 is reduced in diameter and a diameter-reducing force is applied.

[0036] The fixing portion 35 is composed of, for example, a shackle and a bolt, and is connected to a loop portion formed at the rear end of the wire rope main body 31 and has the function of tying it to a standing tree or the like at the installation location.

[0037] The animal trap 1 is configured such that the footplate assembly 20 is placed on the mounting platform 10, the two rope hanging arms 23 of the footplate assembly 20 are opened on both sides and laid down in a mountain shape, and the tip washer portion 33 is wrapped around the outer periphery of the rope hanging arm 23 to apply a radial contracting force, the two rope hanging arms 23 are placed on the two side plate portions 12, 14 on the short sides of the bottom plate portion 11, and the footplate 21 is maintained floating in the drop-down space of the mounting platform 10 with the rectangular periphery of the footplate 21 close to the inside of the four side plate portions 12-15.

[0038] [Capture function] Bait is scattered in suitable places in the mountains and fields, and an animal trap 1 is set at a place where animals to be captured pass by applying the Kobayashi-type attracting and capturing method, and when the foot of the captured animal steps on the footboard 21 and the rope hooking arm 23 rotates upward, the tip washer part 33 comes out upward from the rope hooking arm 23 and is reduced in diameter to capture the foot of the captured animal.

[0039] [Characteristic components] As shown in Figures 2 and 3, the two side plate portions 12, 14 on the short sides of the bottom plate portion 11 of the mounting table 10 have table portions 12a, 14a that rise vertically from the bottom plate portion 11 and extend horizontally outward, supporting each arch portion 23b of the rope hanging arm 23 in a tilted mountain shape without protruding outward, and the two side plate portions 13, 15 on the long sides of the bottom plate portion 11 do not have an opening to introduce light from the outside of the tip washer portion 33 into the inside, and are configured to rise in a mountain shape to the extent that the two rope hanging arms 23 in a tilted mountain shape placed on the table portions 12a, 14a cannot be seen when viewed from the outside.

[0040] The rope hanging arm 23 has two legs 23a, 23a extending to the corners of the long side of the footboard 21, and an arch portion 23b that is an arcuate shape that connects the other ends of the two legs 23a, 23a together; when the rope hanging arm 23 is opened in a mountain shape, it protrudes outward in the long side of the footboard 21 and is placed on the table portions 12a, 14a, and the arch portion 23b does not protrude outward beyond the table portions 12a, 14a.

[0041] It is necessary to cover the top surfaces of the footboard 21 and the table parts 12a, 14a with soil so that the animals cannot see their presence. If there is a step between the footboard 21 and the table parts 12a, 14a, it is necessary to cover the lower one with more soil to eliminate the step, and the step will increase the gap between the two, so that if it rains, a large amount of soil will flow into the placement platform 10 through the gap and pile up high, which may lead to "empty splashing". To avoid this, in this embodiment, the rope hanging arms 23, 23 are inclined downward on both sides and opened in a mountain shape, and the tip washer part 33 is further wound around the outer periphery, so that the rope hanging arms 23, 23 are in a stable state in which they abut against the short side edge of the footboard 21. In this state, the rope hanging arms 23, 23 are supported at both ends by the table parts 12a, 14a and the footboard 21 can be held in a floating state, so that the footboard 21 and the table parts 12a, 14a are at approximately the same height. Here, as described above, when the rope hanging arms 23, 23 are inclined downward on both sides and open in a mountain shape, the footboard 21 is normally positioned higher than the table parts 12a, 14a, but in this embodiment, the leg parts 23a and the arch parts 23b of the rope hanging arms 23, 23 are slightly bent at the connecting parts, so that the entire length of the lower end of the arch parts 23b is in close contact with the table parts 12a, 14a, and the top surfaces of the footboard 21 and the table parts 12a, 14a are at the same height. With this configuration, even if the inclination angle of the rope hanging arms 23, 23 is large, the top surfaces of the footboard 21 and the table parts 12a, 14a can be at the same height, so the strength for the rope hanging arms 23, 23 to jump up can be increased, and the rope hanging arms 23, 23 can be prevented from jumping up even if a small animal steps on the footboard 21.

[0042] In addition, if the arch portion 23b of the rope hanging arms 23, 23 on the swinging side is slightly bent from the point where it abuts against the short side edge of the footboard 21 so that the entire length of the lower end is in close contact with the table portion 12a, 14a, the angle of the rope hanging arms 23, 23 opening in the mountain shape can be increased, and the footboard 21 can be enlarged for the rope hanging arms 23, 23 to jump up due to the tightening of the tip washer portion 33.

[0043] A rough surface portion 21c is provided on the upper surface of the footboard 21. The rough surface portion 21c is formed by applying a coating material containing solid particles, for example, to prevent soil from flowing away when it is applied to cover the upper surface to hide it from animals.

[0044] 1, 2 and 4, the capture wire rope 30 is wound around the outer circumference of the two rope hooking arms 23 with the tip flaps 33 open in a mountain shape so that the ring portion 32 is located at the arch portion 23b of the rope hooking arm 23 on one of the table portions 12a, 14a, and the wire rope main body 31 and wire rope tension spring 34 extending outward from the ring portion 32 are passed over the table portions 12a, 14a. By passing the wire rope main body 31 and the wire rope tension spring 34 over the table portions 12a, 14a, it is no longer necessary to provide openings in the two side plate portions 13, 15 on the long sides for passing the wire rope main body and the wire rope tension spring, as was conventionally the case, and the intrusion of soil and sand has been eliminated.

[0045] The hinge ribs 22, 22 rise in a mountain shape on the inside of each rope hanging arm 23 to the extent that they are not visible when viewed from inside when the two rope hanging arms 23, 23 are placed on the table portions 12a, 14a in a mountain-like position, and work together with the two side plate portions 13, 15 on the long sides of the bottom plate portion 11 to cover the legs of the rope hanging arms 23 so that the feet of the captured animal do not rest directly on them.

[0046] As shown in Figures 2 and 4, the step 21 of the step assembly 20 is rectangular and is close to the inside of the four side panel portions 12-15, and there are no elongated openings formed by cutting and bending the outer portions of the two hinge ribs 22, 22 to provide the hinge ribs 22, 22.

[0047] As shown in Figures 5(A)-(D), the hinge ribs 22, 22 are two angle-shaped members or one channel-shaped member made by bending a plate material of the required shape that is separate from the footplate 21 in order to maintain strength, and are overlapped on the footplate 21 and fixed together by welding, bolting, or other fixing means.

[0048] Fig. 5(A) shows an embodiment in which a channel-shaped member is placed on the top surface of a step plate 21, and the overlapping surfaces of the step plate 21 and the channel-shaped member are welded or bolted together to form hinge ribs 22, 22. Fig. 5(B) shows an embodiment in which a channel-shaped member is placed on the bottom surface of a step plate 21, and the hinge ribs 22, 22 are raised above the step plate 21 through the slits 21a of the step plate 21, and the overlapping surfaces of the step plate 21 and the channel-shaped member are welded or bolted together to form an integrated structure. Fig. 5(C) shows an embodiment in which two angle-shaped members are placed on the bottom surface of a step plate 21, and the hinge ribs 22, 22 are raised above the step plate 21 through the slits 21a of the step plate 21, and the overlapping surfaces of the step plate 21 and the angle-shaped members are welded or bolted together to form an integrated structure. FIG. 5(D) shows an embodiment in which elongated cutouts 21b, 21b are provided on both sides of the step plate 21, and two angle-shaped members are placed on the underside of the step plate 21 so as to cover the elongated cutouts 21b, 21b, thereby raising the hinge ribs 22, 22 above the step plate 21, and the overlapping surfaces of the step plate 21 and the angle-shaped members are integrated by welding or bolting.

[0049] [Technical effect of the animal trap 1 of the present embodiment] The animal trap 1 having the above configuration is an improvement based on the technology of the above-mentioned Patent Document 1, and it is possible to provide an animal trap that can improve the conventional problem of "empty bounce" as follows.

[0050] (1) In the past, when a wild animal's foot stepped on the rope hanging arm, the rope hanging arm would spring up and the tip washer would shrink in diameter, and since the wild animal's foot was not positioned inside the rope hanging arm, there was a high probability of the wild animal hitting the rope. In contrast, in this embodiment, the side plates 13, 15 and hinge ribs 22, 22 of the mounting table 10 on both sides of the leg 23a of the rope hanging arm 23 are slightly higher than the leg 23a, so it is possible to prevent the wild animal's foot from stepping on the rope hanging arm. When the wild animal's foot is positioned slightly inside and steps on the hinge ribs 22, 22 without stepping on the side plates 13, 15, the foot of the wild animal is positioned inside the rope hanging arm 23, so the foot plate 21 sinks, the rope hanging arm 23 springs up, and the tip washer 33 narrows, thereby capturing the wild animal's foot.

[0051] (2) In the prior art, the wire rope body was divided 180° to the left and right at the ring portion to form the tip washer portion. Due to the large bending resistance of the wire rope, when the feet of the captured animal rested on the base plate portion 11 and the base plate portion 11 sank, a delay in the narrowing of the tip washer portion occurred when the two rope hanging arms jumped up, resulting in an "air flick." In contrast, in this embodiment, the ring portion 32 is positioned in the arch portion 23b of the rope hanging arm 23, so that the wire rope body 31 passes straight through the ring portion 32. This reduces the bending resistance of the wire rope body 31 and eliminates the delay in the narrowing of the tip washer portion 33 when the two rope hanging arms jump up, thereby reducing the "air flick."

[0052] (3) It is necessary to cover the platform 10 and the footboard assembly 20 with soil to prevent them from being found by wild animals. In particular, the leading edge of the platform tip 33 and the hinge ribs 22, 22 must be piled high with soil. In the past, large gaps had to be secured between the introduction part of the tip of the mounting platform and both sides of the hinge rib on the bottom plate, which caused a large amount of soil to fall into the mounting platform through the gap between the mounting platform and the footboard. If rain falls and several days pass after the trap is set, the soil that flows into the mounting platform accumulates and the footboard cannot sink, resulting in "empty splash." In contrast, in this embodiment, the side plates 14, 15 of the mounting platform 10, the rope hanging arms 23, 23 and the hinge rib 22 are aligned at approximately the same height, so that a small amount of soil can be covered, and the amount of soil that falls into the mounting platform 10 through the gap between the mounting platform and the footboard is significantly reduced. This eliminates the problem of the bottom plate 11 sinking poorly due to soil accumulated inside the mounting platform 10 when the feet of a captured animal rest on the bottom plate 11 and the bottom plate 11 sinks, thereby reducing the "empty splash" when the two rope hanging arms jump up.

[0053] (4) Because the rope hanging arms 23, 23 are slightly bent at the connection between the leg portions 23a and the arch portions 23b, even if the inclination angle of the rope hanging arms 23, 23 is increased, almost the entire length of the lower end of the arch portions 23b is in close contact with the table portions 12a, 14a, and the upper surfaces of the footboard 21 and the table portions 12a, 14a are at the same height. This prevents the gap between the footboard 21 and the table portions 12a, 14a from becoming large due to a step, and less soil covering the footboard 21 and the table portions 12a, 14a flows into the support platform 10. In addition, the strength with which the rope hanging arms 23, 23 jump up can be increased, so that the rope hanging arms 23, 23 will not jump up even if a small animal steps on the footboard 21.

[0054] , (5) When setting up the animal trap 1 using the Kobayashi-type lure capture method, even if stones arranged around the trap are brought into contact with the mounting base 10, the rope hanging arms 23, 23 do not become inoperable, and instead the stones serve as a positioning means for the mounting base 10.
