Description

[Technical Field]

[0001] The present invention relates to a box trap for capturing wild animals such as raccoons, palm civets, raccoon dogs, deer, wild boars, and bears, which are considered to be harmful animals. [Background technology]

[0002] Box traps are known as one of the measures to prevent damage caused by wild animals. A box trap is a device for capturing wild animals, and is equipped with a box cage section with an entrance for wild animals to enter, a door body that can be opened and closed in the vertical direction and is installed at the entrance of the box cage section, and a trigger mechanism that closes the door body (Patent Documents 1 to 4). Box traps require high rigidity to prevent captured wild animals from escaping, so the box cage and door are made from highly rigid metal materials. For example, cages for small and medium-sized wild animals such as masked palm civets and raccoons use welded wire mesh made of iron wire with a diameter of 2 to 3 mm, while cages for large wild animals such as wild boars, deer, and bears use iron bars with a diameter of 5 mm or more made of welded iron wire or rebar.

[0004] Conventional box traps have the following problems that need to be solved: <1> Conventional box traps are heavy and difficult to transport because all of their components are made of metal, and they are also prone to rust when left exposed to the elements. Furthermore, conventional metal devices are prone to rusting due to the bodily fluids and blood of wild animals, which can lead to problems with durability and operability. <2> Conventional box traps do not take into consideration injuries to captured wild animals. As a result, when excited wild animals rampage inside the cage, they can hit their heads or bodies hard against the metal material, resulting in serious injuries. In some cases, captured wild animals are released into the wild without being killed, but in such cases, it takes a lot of time and money to treat the wild animals. <3> If the metal of a box trap is rusted, just touching it can cut your skin. Therefore, box traps that are left unused for long periods of time not only cause serious injuries to wild animals, but also make it easy for workers to get injured while handling the box traps. <4> Traditional box traps vary in size depending on the size of the wild animal being captured. Therefore, when capturing wild animals of different sizes, it is necessary to prepare box traps of different sizes. <5> Metal box traps can become deformed or damaged if a wild animal becomes violent or if the trap is accidentally dropped or hit. If the metal material that makes up the box trap becomes deformed or damaged, not only is it difficult to repair the metal material, but it can also cause the trigger mechanism to malfunction. <6> In order to reuse a box trap, it is necessary to remove the blood and pieces of meat of the wild animal that have adhered to the inside of the box cage when the wild animal is captured. If the metal material is rusted, it becomes difficult to remove blood and flesh particles that have stuck to the rough surface, making cleaning the box trap a time-consuming and labor-intensive process. <7> In metal traps, bait that wild animals prefer must be placed by removing part of the trap or by workers inserting part of their body into the trap. Therefore, the work of placing the bait is laborious, and there is a possibility that the trigger may be accidentally activated during the work, resulting in injury.

[0005] The present invention has been made in view of the above points, and an object of the present invention is to provide a box trap that can solve the above problems. [Means for solving the problem]

[0006] The present invention is a box trap comprising a rectangular parallelepiped box cage part having an entrance on one side, a gate part having a door body that falls by gravity to close the entrance of the box cage part, and a trigger mechanism that drops the door body of the gate part, and the box cage part formed of a flexible resin material is detachably assembled to the gate part. The trigger mechanism comprises a pair of frame plates standing on the top surface of the box cage part at a distance from each other, a rotary lever pivotally supported between the upper parts of the pair of frame plates via a horizontal support shaft, a lifting body located below the rotary lever and anchored to a vertical guide groove formed in the middle part of the pair of frame plates via a horizontal support shaft so as to be able to move up and down, and a hanging cord connected to the lifting body and having a length that allows it to be hung inside the box cage part, and the rotary lever has upper and lower locking grooves at its upper and lower parts, and is an operating lever connected to the door body. One end of the cable can be anchored in the upper locking groove of the rotary lever, and the support shaft of the lifting body can be anchored in the lower locking groove of the rotary lever. When the support shaft of the lifting body is positioned above the guide grooves of the pair of frame plates, the lifting body functions as a stopper that restricts the free rotation of the rotary lever. When the hanging cord in the cage section is pulled by a wild animal and the lifting body descends, the weight of the door body allows the free rotation of the rotary lever, and the upper locking groove of the rotary lever and the operating cable are released from the anchoring, closing the door. do. In another embodiment of the present invention, the bottom, both side surfaces, top surface and rear end surface of the box / cage portion are made of a resin net material, and the net material is knitted by crossing vertical strands and horizontal strands. In another embodiment of the present invention, the gate section comprises a guide frame detachably attached to the entrance of the box / cage section, and a door body engaged with the guide frame so as to be movable up and down. 。 [Effects of the Invention]

[0007] The present invention has at least one of the following advantages. <1> By using a flexible resin material for the box cage part, the box trap is lighter than conventional ones, improving handling, and there is no need to worry about the box cage part rusting even if it is left outdoors for a long period of time. In particular, even if the wild animals to be captured become larger, there is no need to use heavy steel bars as material for the box cage, making it extremely easy for workers to transport the box trap to the site. <2> The cage section is made of resin to prevent injuries to wild animals. Therefore, even if a wild animal runs wild inside the box cage, there is absolutely no need to worry about it being seriously injured, and even if the wild animal is kept in the box trap for a long period of time, a high level of safety for the wild animal can be maintained. <3> Even if the box trap is accidentally dropped or hit against a hard member while being handled, the resin net material that constitutes the box cage part will simply undergo elastic deformation and will not be damaged, making it highly durable. <4> Even if an impact force acts on the trigger mechanism provided on the top surface of the box-cage part, the impact force can be absorbed by the elastic deformation of the box-cage part, so the trigger mechanism is unlikely to be damaged. Therefore, failure to capture wild animals due to malfunction of the trigger mechanism is eliminated. <5> Since the box cage part is made of resin, blood and pieces of meat of wild animals hardly adhere to the inner surface of the box cage part, so the box trap can be reused without repairing or cleaning the box trap on a large scale. Even if the body fluids or blood of wild animals adhere to the cage part, rust will not occur. <6> Since the box cage section or gate section that constitutes the box trap can be replaced individually, if either the box cage section or the gate section becomes worn or damaged, it can be replaced with a new component, allowing the box trap to continue to be used. <7> The box cage and gate parts that make up the box trap are detachable, so the trap can be used by replacing the box cage part according to the size of the wild animal to be captured. <8> When a trigger mechanism is formed by combining a rotary lever and a lifting body, even if a wild animal moves the lifting body slightly downward, the stopper of the rotary lever is released and the rotary lever rotates widely. Therefore, the trigger mechanism is less susceptible to the magnitude of the downward pulling action of the lifting body performed by the wild animal, and the operation accuracy of the trigger mechanism is higher than that of conventional methods. <9> Since the box cage part is formed from a flexible resin net material, bait can be placed on the trigger mechanism inside the box cage part from outside the box cage part through the gap between the net material and the trigger mechanism. This means that the bait installation work does not take much time, and there is no risk of injury to workers if the trigger mechanism is accidentally activated during work.

[0009] The present invention will be described in detail below with reference to the drawings.

[0010] <1> Box Trap Overview Referring to Figures 1 and 2, the box trap 10 of the present invention comprises a rectangular box cage section 20, a gate section 30 that closes the entrance 21 of the box cage section 20, and a trigger mechanism 40 that drops the door body 31 of the gate section 30. In the present invention, the gate portion 30 is made of a metal material, while the box-cage portion 20 is made of a flexible resin material. The gate portion 30 and the box-cage portion 20 are detachable. The configuration of the box trap 10 will be described in detail below.

[0011] <2> box cage part Explaining with reference to FIGS. 1 to 3, the box / cage part 20 has a rectangular parallelepiped shape and has a bottom surface 22, left and right side surfaces 23 and 24, a top surface 25, and a rear end surface . The box / cage portion 20 has an entrance 21 on the front end face side. Each of the surfaces 22 to 26 constituting the box / cage portion 20 is formed of a resin net material. The resin net material is a mesh-like material in which a fiber net fabric is impregnated with or coated with resin. The external dimensions (height, width, depth) of the box / cage section 20 can be changed according to the size of the captured animal.

[0012] The surfaces 22 to 25, excluding the rear end surface 26, may have a structure that is continuous, or all the surfaces 22 to 26 may have separate and independent structures. When the surfaces 22 to 25 are formed with systematic continuity, the butted edges of both ends are connected with known connectors (wire clips, C-rings, cable ties, etc.) to form a rectangular parallelepiped shape. When the surfaces 22 to 26 are formed in separate shapes, adjacent edges are connected with known connectors to form a rectangular parallelepiped shape.

[0013] Figure 4 shows an example of a resin net material. This net material is formed by knitting vertical strands 27 and horizontal strands 28 so that they intersect, and knitting bent portions 29 parallel to the horizontal strands 28 in a part of the net material. The bent portion 29 can be formed at any position on the net material.

[0014] <3> Gate section 1, 2, and 5. The gate unit 30 comprises a vertically long guide frame 31 detachably attached to the entrance 21 of the box / cage unit 20, and a door 35 that engages with the guide frame 31 so as to be movable up and down and that can close the entrance 21.

[0015] <3.1> Guide frame The guide frame 31 comprises a pair of vertical frames 32, 32 spaced apart, a beam frame 33 extending between the heads of the vertical frames 32, 32, and an attachment flange 34 (Figure 5) that can be fitted into the entrance 21 of the box cage section 20.

[0016] <3.2> Door engagement structure The vertical frame 32 has a guide groove 32a along its entire length (FIG. 2). The door body 32 is engaged with the guide grooves 32a of the pair of vertical frames 32, 32. The door body 32 can fall under its own weight.

[0017] <3.3> Connection structure between guide frame and cage The guide frame 31 constituting the gate section 30 and the entrance 21 of the box / cage section 20 are detachable.

[0018] The connecting structure shown in FIG. 5 will be explained. A mounting flange 34 protruding laterally from the lower half of the pair of vertical frames 32, 32 can be mounted on the exterior or interior of the entrance 21 of the box / cage portion 20. The mounting flange 34 cooperates with the pressure plate 36 to sandwich the box cage section 20 therebetween, and by tightening it with a mounting bolt 37, the guide frame 31 and the box cage section 20 can be connected, and by removing the mounting bolt 37, the guide frame 31 and the box cage section 20 can be separated.

[0019] The reason why the guide frame 31 constituting the gate section 30 and the entrance 21 of the box cage section 20 are configured to be detachable is to enable partial replacement of the components in the smallest unit when either the guide frame 31 or the box cage section 20 is damaged, and to enable replacement with a different box cage section 20 having a different depth dimension without replacing the guide frame 31.

[0020] <3.4> Door body As shown in FIGS. 1 and 2, the door body 35 is a gravity-drop type door capable of closing the entrance 21 of the box / cage section 20. The door body 35 may be a plate body or a mesh body. Both sides of the door body 35 are engaged with the vertical frames 32 of the guide frame 31. The door body 32 is positioned directly above the entrance 21 of the box cage part 20 through the trigger mechanism 40, and falls under its own weight when the trigger mechanism 40 closes the door, thereby closing the entrance 21.

[0021] <4> Trigger mechanism As shown in FIG. 1, the trigger mechanism 40 is an operating mechanism for causing the door body 32 constituting the gate unit 30 to fall by its own weight when it is confirmed that a wild animal has entered the box / cage unit 20 .

[0022] <4.1> Configuration of the illustrated trigger mechanism The trigger mechanism 40 illustrated in Figures 6 to 8 comprises a pair of frame plates 41, 41 erected at a distance from each other, a pivotable lever 42 pivoted between the upper portions of the pair of frame plates 41, 41 via a support shaft 42a, and a lifting body 43 tethered below the pivotable lever 43 via a support shaft 43a so as to be able to move up and down freely.

[0023] <4.1.1>Frame plate The pair of frame plates 41, 41 are plates for pivotally supporting the rotary lever 42 and the lifting body 43, and are fixed to the upper surface 25 of the box cage portion 20 with a cable tie or the like. A vertically oriented elongated guide groove 41a is provided in the middle of the pair of frame plates 41, 41, and a support shaft 43a of the lifting body 43 is engaged with this guide groove 41a, so that the lifting body 43 can be raised and lowered along the guide groove 41a.

[0024] <4.1.2> Rotating lever The rotating lever 42 is a control member that cooperates with the lifting body 43 to maintain the hanging state of the door body 35 and to allow the door body 35 to fall under its own weight. The rotating lever 42 has a support shaft 42a in the middle thereof, and is pivotally supported on the upper part of the pair of frame plates 41, 41 via the support shaft 42a. The rotating lever 42 is provided at its upper and lower parts with an upper locking groove 42b and a lower locking groove 42c. One end of an operating cable 50 can be anchored in the upper locking groove 42b of the rotating lever 42, and the support shaft 43 of the lifting body 43 can be anchored in the lower locking groove 42c of the rotating lever 42.

[0025] <4.1.3> Lifting body The lifting body 43 is a stopper member for controlling the rotation of the rotating lever 42 . The lift body 43 has a horizontal support shaft 43a integrally formed on the upper side thereof. A guide groove 41a is provided in the middle of the pair of frame plates 41, 41 in a vertical direction, and a support shaft 43a of an elevator body 43 is engaged with this guide groove 41a, so that the elevator body 43 can rise and fall along the guide groove 41a. A hanging string 45 is connected to the lifting body 43 via a hook 44 or directly. The hanging string 45 is for attaching food that wild animals like to eat, and has a length that allows it to hang down inside the cage section 20.

[0026] <4.2> Reason for combining the rotating lever and the lifting body It is also possible to consider a trigger mechanism in which the lifting body 43 is omitted and the hanging string 45 is connected to the lower end of the rotating lever 42, but without the lifting body 43, not only would a new stopper for the rotating lever 42 have to be devised, but if the rotation angle of the rotating lever 42 is small, the operating cable 50 will not be able to be securely detached from the rotating lever 42, causing problems such as the trigger mechanism not functioning properly. In the present invention, in order to eliminate such inconvenience, a combination of a rotary lever 42 and a lifting body 43 is adopted.

[0027] <4.3> Control cable The operating cable 50 is a rope material that connects between the upper locking groove 42 b of the rotating lever 42 of the trigger mechanism 40 and the upper part of the door body 32 . As shown in FIGS. 1 and 2, the middle of the operation cable 50 is directly moored to the beam frame 33 or indirectly moored via a pulley (not shown) provided on the beam frame 33.

[0028] <4.4> Trigger mechanism operation 7 and 8, the operation of the exemplary trigger mechanism 40 of the present invention will now be described.

[0029] <4.4.1> Door opening operation When the trigger mechanism 40 is set to open the door, the support shaft 43a of the lifting body 43 is positioned above the guide groove 41a and is engaged with the lower engaging groove 42c provided in the rotating lever 42. The support shaft 43a of the lifting body 43 is engaged with a lower engagement groove 42c provided in the rotating lever 42, so that the rotation of the rotating lever 42 in the pulling direction (clockwise direction in the drawing) is restricted within a certain range. Therefore, the pulling force acting on the upper part of the rotating lever 42 through the operating cable 50 is supported by the engagement between the stationary rotating lever 42 and the lifting body 43. At this time, the lifting body 43 functions as a stopper that restricts the rotation of the rotating lever 42 . Therefore, the upper locking groove 42b of the rotating lever 42 and the operating cable 50 are kept in a locked state.

[0030] <4.4.2> Door closing operation The trigger mechanism 40 can close the door by the following operation. Referring to FIG. 8, when the lifting body 43 is forcibly pulled downward by a wild animal, the lower locking groove 42c of the rotating lever 42 and the support shaft 43a of the lifting body 43 are disengaged. When the engagement between the rotary lever 42 and the lifting body 43 is released, the rotary lever 43 becomes rotatable. A tensile force in the counter-pulling direction (counterclockwise in the drawing) is constantly acting on the upper part of the pivot lever 42 through the operating cable 50, so the moment the pivot lever 42 and the lifting body 43 are disengaged, the pivot lever 42 rotates in the counter-pulling direction (counterclockwise in the drawing), and the pivot lever 42 and the operating cable 50 are released from their engagement. When the upper locking groove 42b of the rotating lever 42 and the operating cable 50 are released from each other, the door body 35 falls by its own weight and closes the entrance 21 of the box cage section 20.

[0031] <5> Other trigger mechanisms The trigger mechanism 40 is not limited to this example, and it is also possible to apply a known kick string type, footplate type, or rotary shaft type.

[0032] [How to use a box trap] The method of using the box trap 10 will be described with reference to FIGS.

[0033] <1> Storing box traps The box cage part 20 and the gate part 30 that constitute the box trap 10 can be stored in a separated state. In particular, since the box / cage part 20 is made of a resin material, it can be stored in an unfolded or folded state, so that less storage space is required.

[0034] <2> Bringing the box trap to the site The box trap 10 described above is carried to the installation site. Since the box cage part 20 constituting the box trap 10 is made of a lightweight resin material, the ease of transporting it to the site can be greatly improved compared to conventional box traps in which the box cage part is made of metal.

[0035] In particular, the larger the wild animals being captured, such as wild boars and bears, the stronger the materials required, so heavy steel bars have traditionally been used in the cage box. In contrast, in the present invention, even if the wild animal to be captured becomes larger, heavy rebars do not need to be used as the material for the box cage portion 20, so a single worker can carry the box trap 10 to the site.

[0036] Furthermore, even if the box cage part 20 is accidentally dropped or hit against a hard member during transportation of the box trap 10, the fiber net material that constitutes the box cage part 20 will simply undergo elastic deformation and will not be damaged.

[0037] <3> Assembling a box trap Assemble box trap 10 on site. That is, the box cage portion 20 is produced by assembling the net material into a box shape with a bottom. The gate part 30, in which the door body 35 is fitted into the guide frame 31, is connected to the entrance 21 of the box cage part 20 and assembled together. After the trigger mechanism 40 is fixed to the upper surface of the box cage section 20 with a cable tie or the like, the operating cable 50 is connected between the upper locking groove 42b of the rotating lever 42 of the trigger mechanism 40 and the upper part of the door body 32. At this time, the middle of the operating cable 50 is moored to the beam frame 33. The box trap 10 is not limited to being assembled on-site, but may be brought to the site in the form of a completed product.

[0038] After completing the assembly of the box trap 10, the trigger mechanism 40 is set to open the door with the door body 31 positioned above the gate portion 30 (see FIG. 7). The weight of the door body 31 is supported by the box / cage part 20 through the operating cable 50 and the trigger mechanism 40.

[0039] A hanging string 45 connected to the lifting body 43 is attached with food 46 that is popular with wild animals. The work of attaching the bait 46 can be carried out inside the box cage section 20, but it is also possible to attach the bait 46 to the tip of the hanging string 45 from outside the box cage section 20 by passing the hanging string 45 through the mesh of the net material that makes up the box cage section 20 or through the gap with the trigger mechanism. Therefore, even if the trigger mechanism 40 is accidentally activated during the work of placing bait, there is no risk of injury to the worker.

[0040] <4> Leaving a box trap The box cage part 20 is left in an open state in a habitat of wild animals. Even if the box trap 10 is left exposed to the elements for a long period of time, there is no risk of the box cage part 20 made of a resin material rusting.

[0041] <5> Wild animal capture A wild animal enters the cage section 20 through the entrance 21 and pulls the food 46 attached to the hanging string 45 inside the cage section 20 in an attempt to eat it. When the hanging cord 45 is pulled downward, the stopper function of the trigger mechanism 40 is released. As a result, the operating cable 50 is disconnected from the trigger mechanism 40. When one end of the operating cable 50 is released from the trigger mechanism 40, the door body 31 falls by its own weight, the entrance 21 of the box cage part 20 is instantly closed, and the wild animal is captured in the box trap 10.

[0042] After being captured, the wild animal will run wild in the cage section 20. Since the box cage part 20 is made of a resin material, there is no risk of the wild animal being seriously injured even if it rampages around inside the box cage part 20, and since the box cage part 20 has flexibility, there is no risk of the box cage part 20 being broken even if the wild animal collides with it.

[0043] <6> When reusing a box trap Once the captured wild animal is removed from the box cage section 20, the box trap 10 is reused. When the box trap 10 is reused, the box cage part 20 is little damaged and the blood and pieces of meat of wild animals hardly adhere to the inner surface of the box cage part 20, so the box trap 10 can be reused without repairing or cleaning the box trap 10 on a large scale.

[0044] <7> Partial replacement of components of a box trap The box cage section 20 or the gate section 30 that constitutes the box trap 10 is structured so that it can be replaced individually. Therefore, if either the box cage section 20 or the gate section 30 becomes worn or damaged, the box cage section 20 and the gate section 30 can be separated and replaced with new components, allowing the box trap 10 to continue to be used.

[0045] Furthermore, if the wild animal to be captured changes, the box cage section 20 made according to the size of the wild animal can be selected and replaced for use. In this case, the dimensions of the entrance 21 of the box cage part 20 are not changed, and the box cage part 20 at the back of the entrance 21 is replaced with a larger one, or replaced with a box cage part 20 with a different depth dimension.
