Abstract

To address such a problem that in recent years, wildlife damage prevention measures have become an urgent issue in agricultural and mountainous areas, however, hunting is prohibited for unlicensed individuals under the Wildlife Protection and Management Act, means available thereto are limited, it is also difficult to spread the means sufficiently due to problems with their effectiveness and cost, and there is an urgent need for effective, safe and economical wildlife damage prevention measures that can be taken by ordinary people without being subjected to the regulations.SOLUTION: Traps, including snare traps, are subjected to regulations of the Wildlife Protection and Management Act because they are used to capture harmful animals. There is proposed an animal shackle mounting device that solves the problem by mounting a shackle with a sound tool, etc. on a harmful animal without capturing it, and then allowing the animal to escape. The device is configured to release connecting means by utilizing force of the harmful animal trying to escape immediately after the shackle is attached, and the device can be used for relatively large harmful animals such as wild boars, as well as for small harmful animals such as masked musang by using trigger means with increased sensitivity.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] The present invention relates to an animal shackling device for preventing harmful animals from invading or approaching fields or the like from invading human activity areas by imposing a certain burden and sense of caution on the harmful animals without capturing them. [Background technology]

[0002] In recent years, the depopulation and aging of residents in rural areas has led to an increase in the numbers of wild animals, causing serious damage to agriculture and forestry, and dealing with this has become a major nationwide issue. The first way to deal with this is to manage the population of harmful animals, but Japan has the Wildlife Protection and Management Act, which prohibits extermination or capture without a hunting license and administrative permission.

[0003] One of the methods of capturing animals, particularly wild boars and deer, that can be used by licensed hunters is the use of a snare made of wire. As shown in the two documents below, a method of lifting the snare ring above the legs of the animal has been well known. Although snare traps are simpler and more economical than other methods such as hunting guns and box traps, one problem is that they are dangerous.

[0004] On the other hand, what ordinary people without hunting licenses can do is to prevent intrusions, and the most convenient traditional method is to scare animals away with noise. There are loud devices such as firecrackers, but birds and animals hate having their location revealed by noise made nearby, and many of them will run away just because of this, so there are devices on the market that take advantage of this habit and electronically detect the approach of birds and animals and emit alarms and lights. However, birds and animals soon learn that these methods are only mild threats, so their effectiveness is limited.

[0005] A more reliable traditional method is to fence around the farmland. Various fences and nets are commercially available for this purpose, but they require strong wire mesh and posts of sufficient height to protect against powerful pests, which is expensive for large farmland, and are ineffective against pests that can climb or burrow through the fence. An alternative is electric fencing, but it is also not foolproof and has its own economic problems. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent No. 6908305 [Non-patent literature]

[0007] [Non-Patent Document 1] "Yamaguchi Prefecture Trap and Disposal Manual", published by Yamaguchi Prefecture Environment and Lifestyle Department, Nature Conservation Division, March 2019, pp. 2-4 Summary of the Invention [Problem to be solved by the invention]

[0008] Thus, although rural areas in Japan have been hit hard by wildlife in recent years and measures to combat this problem have become an urgent issue, ordinary people involved in agriculture and forestry are generally prohibited from hunting or capturing wildlife under the Wildlife Protection and Management Act, and the only conventional measures available are mainly the installation of protective fences or electric fences. The problem which this invention aims to solve is to provide a safe and effective means of self-defense that can be implemented by the general public without being subject to the above-mentioned regulations for a wide range of pests, i.e., a method of dispersing pests from an area they have invaded without capturing them and then scaring them from approaching again, thereby preventing the intrusion of pests into agricultural and mountainous areas, in an economical manner. [Means for solving the problem]

[0009] The invention described in claim 1 to solve the above problem is as follows: A frame body having a substantially circular opening on the upper surface and a handle of a certain length at the rear at the same height as the upper surface of the opening, and a step board that is located within or below the opening and can be moved down, A ring is provided which is easily contractible by passing a thin metal strip or wire through a fastener, and the ring is hung around the upper end of the step which protrudes slightly from the upper surface of the opening, or around a surrounding member which forms a substantially circular outline on the upper side of the peripheral end of the step; The shackle ring is provided with a sound device that produces a sound by vibration and / or a foot strap that applies a certain load to the feet of the harmful animal, A resilient device is provided on the handle for generating a biasing force for compressing the shackle ring, A connecting means is provided for temporarily connecting the catch member body provided at the front end of the spring to the catch seat provided at the rear end of the shackle ring, and the connecting means is configured to release the connection when a certain force is applied, and a fixed rope of a certain length is provided at the rear of the catch member body to the ground, A trigger means is provided which biases the spring mechanism to temporarily hold the step plate substantially horizontal, and when the harmful animal steps down on the step plate, instantly releases the bias of the spring mechanism to reduce the size of the snaring ring; Thus, this is an animal shackling device that is configured such that after the sound device and / or the leg harness device are attached to the legs of the pest, the connection by the connecting means is released by the tensile force exerted by the pest, thereby releasing the pest.

[0010] The invention described in claim 2 is as follows: A first lever is provided, the front part of the first lever is fixed to the footboard or the housing member, the rear end part is rotatably attached to a first lever support base provided at the lower part of the frame body or the handle, a trigger metal having an upward protrusion is provided somewhere in the middle part, and a hole through which the trigger metal passes is provided in the frame body or the handle, The animal shackle attachment device of claim 1 has a trigger means configured to connect the connecting means to bias the spring mechanism and to insert the trigger core into a core receiving hole provided at the rear of the catch member main body to temporarily hold the footplate, and when the pest steps down on the footplate, the first lever rotates to cause the trigger core to come out of the core receiving hole, instantly releasing the bias of the spring mechanism and shrinking the shackle ring.

[0011] The invention described in claim 3 is In the animal shackling device according to claim 2, The first lever is extended a certain distance rearward from the pivoting position, and further, a long window is provided in the handle, and a second lever is provided so that its front end temporarily overlaps the rear end of the first lever, and the rear end of the second lever is pivotally attached to a second lever support base provided at the bottom of the handle, The front end of the second lever has a height equal to the upper surface of the handle, and further has a tray on the front for temporarily placing a part of the tie ring and the connecting means, and the tray has a hole through which the trigger core passes, When the pest steps down on the footboard, the rotation of the first lever causes the second lever to rotate as well, and the force of the spring is instantly released, causing the shackle ring to shrink and jump up, after which the front end of the second lever disengages from the rear end of the first lever, and the second lever and the tray return to their original positions.This is an animal shackle attachment device.

[0012] The invention described in claim 4 is In the animal shackling device according to claim 2, The housing member is an inner cylinder having the footboard as a bottom plate, and the inner cylinder is fixed to a front end of the first lever, This is an animal shackle attachment device in which the shackle ring is hung around the upper end of the inner tube inserted into the opening.

[0013] The invention described in claim 5 is The frame body is cylindrical and serves as an outer cylinder, and the housing member is an inner cylinder with the step plate as a bottom plate. The inner cylinder is fitted into the outer cylinder so as to be movable up and down, and the tether ring is hung around the upper end of the inner cylinder. The animal shackle attachment device of claim 1 has a trigger means that has a structure in which the spring mechanism is energized to connect the catch member main body and the receiving seat, thereby pulling the shackle ring and temporarily holding the footplate, and when the pest steps down on the footplate, the shackle ring is pushed up to the inner edge of the outer tube and detached from the inner tube, and the force of the spring mechanism is instantly released to shrink the shackle ring.

[0014] The invention described in claim 6 is as follows: The housing member is composed of a pair of side plates provided upward at the front and rear of the peripheral end of the step, and a pair of half-loop-shaped guides rotatably attached to the side plates symmetrically, and the tie ring is hung around the guide so that the guide straddles the opening from left to right, The animal shackle attachment device of claim 1 has a structure in which the spring mechanism is energized to connect the catch member main body and the receiving seat, thereby pulling the shackle ring, the guide forms a slight V-shape to temporarily hold the footplate, and when the pest steps down on the footplate, the left and right sides of the guide are reversed and the shackle ring is released, and the force of the spring mechanism is instantly released to cause the shackle ring to shrink and jump up, thereby serving as the trigger means.

[0015] The invention described in claim 7 is as follows: A plurality of said binding rings and said footboards each having said sound tool and / or said foot strap and said seat are provided, and all said footboards are integrally connected by one connecting arm provided on the underside of said frame body, All of the receiving seats are connected to one of the catch member bodies, An animal shackling device as described in any one of claims 2 to 4, which is configured to energize the spring mechanism to temporarily hold all of the steps, and when the pest steps down on any of the steps, the trigger means is activated to shrink the shackle loop that the pest has stepped on. Effect of the Invention

[0016] According to the invention described in claim 1, by simply attaching a certain attachment to a harmful animal using a snaring ring, the harmful animal is released without being killed or injured. This provides an effective means of controlling harmful animals that can be used by ordinary people without a hunting license without being subject to the restrictions of the above law. Furthermore, the work required for control is safe and easy, without causing harm to harmful animals. In addition, since the diameter of the snare ring and the diameter of the wire can be freely selected, the device can target a wider range of pests than a snare trap, the success rate is increased, and the device can be made lighter.

[0017] Next, when harmful animals step down on the steps of this device which are installed around fields or on the animal trails leading to them, at least one of the following two effects can be obtained. First, a sound device that emits some kind of sound when vibrated is attached to the leg of the device, and when the vermin is startled and tries to escape, the shackle ring comes off the device due to its own strong movement, so the vermin escapes with the sound device still attached, making it sound as a part of the shackle. After that, the vermin will make a sound every time they move, so it will be difficult for them to approach human living areas, and if they do approach, it will be easier for people to detect them. Secondly, it is possible to equip the animals with leg restraints that place a certain amount of strain on their legs. This places a certain limit on their future activity, making them more cautious and more effectively preventing them from re-approaching agricultural and mountainous areas.

[0018] In terms of cost, this device only requires attaching a relatively light component to the vermin, so it can be made of less strength than a snare trap, and is less susceptible to damage from vermin, so it can be used repeatedly for a long period of time by simply replenishing the snare rings and their accessories. This reduces the cost of vermin control. The above-mentioned effects are common to all of the inventions described in claims 2 to 7.

[0019] According to the invention described in claim 2, the tether is not a component of the trigger means, but the trigger means is centered around the first lever. That is, the spring is temporarily energized to fit the trigger core of the first lever into the core receiving hole of the catch member body, thereby holding the step substantially horizontally, so that the tether is looped around the top end of the step or the frame member without being pulled strongly. Therefore, there is almost no resistance to removing the tether from them. Furthermore, since the trigger core is small in diameter, the resistance to disengagement from the core receiving hole is small, and the downward force of the trigger core is increased by the effect of the first lever as a lever, so the sensitivity of the trigger means is increased. Therefore, the present invention is easily effective not only against relatively large pests such as wild boars and deer, but also against relatively small pests such as masked palm civets.

[0020] According to the invention described in claim 3, when the trigger means is activated, the second lever flips up the tether, so that the attachment is attached to the upper part of the pest's leg, making it more difficult for the pest to come off. Also, the second lever and the tray return to their original positions immediately after flipping up the tether, so they do not become entangled with the fixing device until the pest is released.

[0021] According to the invention described in claim 4, the footboard can be installed at a position lower than the ground by the depth of the inner tube, so the snares can be automatically and securely attached above the legs of the pests. It is a relatively simple and durable structure, yet has the same effect as the invention described in claim 3.

[0022] According to the invention described in claim 5, the trigger means does not include a lever member, a trigger core bar, or a core receiving hole, and the foot plate is held by temporarily energizing the spring and wrapping the tie loop around the inner tube fitted into the outer tube. Therefore, in exchange for the lower sensitivity of the trigger means compared to the inventions described in claims 2 to 4, the device can be made simple, inexpensive, and sturdy.

[0023] According to the invention described in claim 6, like the invention described in the previous paragraph, there is no lever member, trigger core bar, or core receiving hole, and the spring is temporarily energized to wind the tether around the guide, holding the footboard, and when a pest steps down on the footboard, the guide, which has a slight V-shape, reverses and powerfully springs up the tether. Therefore, in exchange for the lower sensitivity of the trigger means compared to the inventions described in claims 2 to 4, the function of springing up the tether can be strengthened.

[0024] According to the invention described in claim 7, multiple tethers are provided on one device, and no matter which one a pest steps on, the tether will be attached to the leg of the pest, increasing the success rate of attachment. Note that the inventions described in claims 5 and 6 are not suitable for application of this claim, since the load required for the footboard becomes large and the sensitivity of the trigger means becomes even lower.

[0026] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. EXAMPLES

[0027] A first embodiment of the device according to the present invention will be described with reference to FIGS. In Figure 1, the frame 1 is a horseshoe-shaped platform frame of a certain height, and a circular step 2 is temporarily fitted into the opening 1A so as to loosely cover it from below. The step 2 protrudes slightly above the upper surface of the opening 1A, and a tie ring 3, which is made by passing a thin metal band 3A through a fastener 4, is hung around it without being pulled tightly, simply to determine its position and shape. A spring 6 is fixed to the rear of the handle 1B, which is provided at the same height as the upper surface of the frame 1, via a sheath 6A and a fixing bracket 6B, and the spring 6 and the binding ring 3 are connected by a connecting means 8.

[0028] An example of the details around the shackle ring 3 is shown in Figure 2. In this example, the shackle ring 3 is similar to a known metal cable tie, and is composed of a thin band 3A and a fastener 4 attached to its front end. This fastener 4 generally uses a mechanism called a ball lock type that makes it easy only to reduce the size of the loop, but the present invention is not limited to this type. The thin belt 3A can be replaced with a rope 3B as the tie ring 3, but an explanation of this case including the fastener 4 will be given later in the fifth embodiment.

[0029] The rear end of the narrow belt 3A is provided with a catch 82, which is a hook shaped to prevent accidental removal, and the sound tool 5 and the foot strap 10 are connected just in front of it. The catch 82 engages with the catch member body 81, forming the connecting means 8, and the tip of the catch member body 81 made of spring steel opens when a certain amount of pulling force is applied, and the connection is released. The rear of the catch member body 81 is provided with a core receiving hole 81A, and the rear of the catch member body 81 is connected to the spring 6 and a fixed rope 9 of an appropriate length whose rear end is fixed to the ground. There are many types of catch members known, including a magnet type, but the present invention is not limited to that type.

[0030] In the figure, the sounding device 5 and the foot strap 10 are shown at the rear of the thin belt 3A, but they may both be near the fastener 4, or they may be distributed in front and behind. The sounding device 5 should be one that produces a loud sound when vibrated, and in this example it is shown as two bells. The foot strap 10 in this example is a rectangular piece of iron of a certain weight, and is connected near the center of its upper edge with a wire of an appropriate length, so that not only is it heavy, but it can also entangle with the surrounding vegetation as the pest walks through the fields and mountains, putting a certain amount of strain on it. The foot strap 10 may be rod-shaped, but in either case it is effective to connect it at the center in the left-right direction.

[0031] With this configuration, when the spring mechanism 6 is pulled to engage the trigger core 71 with the core receiving hole 81A and at the same time the catch member body 81 and the receiving seat 82 are connected, when the trigger means described later is activated and the engagement of the trigger core 71 is released, the snaring ring 3 is pulled backward and at the same time the front part shrinks because it is caught on the pest's leg. Then, when the pest tries to escape and pulls further due to its own violent movement, most of the load is transferred from the spring mechanism 6 to the fixing rope 9 due to the constraints of the length of the fixing means 9, and when the binding progresses and the load exceeds a certain level, the connection means 8 is released and the pest escapes with the sound device 5 and / or the leg binding device 10 still attached.

[0032] FIG. 3 is a cross-sectional view taken along the center line of the device of the first embodiment, which is installed approximately horizontally in the ground hole 11, and will be used to explain the structure of the trigger means. The front end of the first lever 72 is fixed to the center of the lower part of the footboard 2, and its rear end is pivoted to a first lever support base 73 provided at the lower part of the frame 1 or, depending on the position, the handle 1B, so that it can freely rotate about the axis. A trigger mandrel 71 is fixed to the first lever 72 in the form of an upward protrusion forward of the rear end, which passes through a hole 1C provided in the frame 1 and is inserted into a core receiving hole 81A and pulled backward by the spring mechanism 6, so that the first lever 72 is supported parallel to the frame 1, and the footboard 2 fits into the opening 1A to close it. Therefore, since the spring mechanism 6 does not apply a load to the tether 3 when setting the trap, there is almost no resistance when removing the tether 3 from the footboard 2. When a vermin then steps down on the footboard 2, the trigger core 71 moves strongly downward with little resistance and comes out of the core receiving hole 81A due to its small diameter and the action of the first lever 72 as a lever, so that the trigger means operates sensitively even with a small force. EXAMPLES

[0033] A second embodiment of the device according to the present invention will be described with reference to FIGS. As shown in Figure 4, in this example, the basic configuration of the frame 1, handle 1B, step 2, tether 3, spring mechanism 6, connecting means 8, and first lever 72 is the same as in Example 1, but a long window 1D is provided near the front of the handle 1B, adding the function of flipping up the tether 3.

[0034] 5 is a cross-sectional view taken along the center line of the device, in which the first lever 72 is extended by a certain length with a step provided behind the pivot position, and the second lever 74 is provided so that its front end temporarily overlaps the rear end of the first lever 72, and its rear end is pivotally attached to a second lever support base 75 provided at the bottom of the handle 1B. Therefore, when the footboard 2 pivots downward, the rear end of the first lever 72 kicks the front end of the second lever 74 upward above the long window 1D. The front end of the second lever 74 has a height up to the upper surface of the handle 1B, and furthermore, a tray 76 for placing part of the tether 3 and the connecting means 8 is fixed together with left and right support plates 76A, which are provided with a hole 76B through which the trigger mandrel 71 can pass. Therefore, the moment the vermin steps down on the footboard 2, the trigger mandrel 71 passes through holes 76B and 1C and moves strongly downward to come off the catch member main body 81, and the thin band 3A is pulled backward by the biased spring 6. The tether 3 is then bounced up by the tray 76 above the vermin's leg and shrinks. At this time, as the first lever 72 rotates, its rear end moves forward and upward, while the front end of the second lever 74 moves backward and upward, so that the overlap between the two is released after a certain amount of rotation, and the second lever 74 and tray 76 drop and return to their original positions. Note that the step at the rear end of the first lever 72 is not essential, and if the trigger mandrel 71 is made sufficiently long, for example, the tray 76 will not come into contact with the rear end of the first lever 72 when returning to its original position, making the step unnecessary. EXAMPLES

[0035] A third embodiment of the device of the present invention according to claim 4 will be described with reference to Fig. 6. The rear portion of the handle 1B in this embodiment has the same structure as in the first embodiment, so Fig. 6 shows only the frame 1 and its surroundings. An inner cylinder 2A, which has a footboard 2 as a bottom plate as an example of a housing member, is fitted from below into the opening 1A of the frame body 1, and the front end of the first lever 72 is fixed to the side of the inner cylinder 2A. Then, the spring 6 is pulled to insert the trigger mandrel 71 into the mandrel receiving hole 81A, supporting the inner cylinder 2A approximately horizontally, and the tie ring 3 similar to that of the first embodiment is loosely hung around the upper end of the inner cylinder 2A. By doing so, the moment the vermin steps down on the treadle 2, the trigger core 71 moves strongly downward and comes out of the core receiving hole 83, and the snare ring 3 is pulled and contracted, just like in the first embodiment. At this time, the snare ring 3 contracts above the vermin's legs by the depth of the inner tube 2A. EXAMPLES

[0036] A fourth embodiment of the device according to the present invention will be described with reference to FIGS. In Figure 7, the frame 1 in this example is an outer tube equipped with a handle 1B, into which an inner tube 2A, which is a casing member with a footboard 2 as its base plate, is fitted so as to be able to move up and down freely. A tie ring 3 similar to that in Example 1 is hung around the upper end of the inner tube 2A, and the rear end of the inner tube 2A can be pulled to tighten it. The connecting means 8 is composed of a catch member body 81 without a core receiving hole at the front end of the spring 6, and a receiving seat 82 provided at the rear end of the tying ring 3. The sound device 5 and the foot strap 10 are provided at the rear of the tying ring 3. The spring mechanism 6 and the fixed rope 9 are connected to the rear of the catch member body 81, and the rear end of the sheath 6A housing the spring mechanism 6 is held swingably at the rear end of the handle 1B by a fixing metal fitting 6B, and the fixed rope 9 is of an appropriate length and its rear end is connected to a fixed object on the ground. This fixing method is effective for protecting the spring mechanism 6, since the connecting means 8 may move in all directions from the time the tether 3 is contracted until the harmful animal is released, and is not limited to this example.

[0037] FIG. 8 is an explanatory diagram showing a cross section taken along the center line of the device placed on the ground, assuming that the spring 6 is on the center line of the device, and will be used to explain the structure of the trigger means. When the spring 6 is temporarily energized to connect the catch member main body 81 and the receiving seat 82, the tether 3 tightens the inner tube 2A while pulling it backward, holding the footboard 2 approximately horizontal. When a harmful animal then steps down on the footboard 2, the tether 3 is pushed up against the inner peripheral edge of the opening 1A and comes off the upper end of the inner tube 2A, jumping onto the harmful animal's leg and shrinking. After the sound device 5 and the foot strap 10 are attached, the connection means 8 is released in the same manner as in Example 1, and the harmful animal is released. EXAMPLES

[0038] A fifth embodiment of the device of the present invention according to claim 6 will be described with reference to Fig. 9. The rear part of the handle 1B in this embodiment is almost the same as in the other embodiments, so Fig. 9 shows only the frame 1. In this embodiment, the snaring ring 3, which has the sounding device 5 connected to its front end, uses a wire 3B, and the fastener 4 uses a metal fitting similar to a known snaring fitting as a part for a snaring trap. This is because the metal fitting is suitable for preventing the snaring ring 3 using the wire 3B from loosening, and this is not the only example, and in any case, it is best to select a fastener 4 that is appropriate for combination with the thin band 3A or wire 3B.

[0039] The frame 1 of this example is a rectangular box with no bottom, and a step 2, which is roughly oval and slightly larger than the opening on both the left and right sides, is provided so that it can move down and temporarily block the opening 1A from below. The step 2 has a pair of side plates 2D facing upward at the front and back of its periphery, and a pair of half-loop guides 2C that straddle the opening 1A on the left and right are axially attached to these symmetrically to form a frame member, allowing it to move up and down on the left and right as shown in the XX direction. A tie loop 3 is looped around the guide 2C, and the rear end is pulled to tighten it. When the trap is set, the spring 6 is pulled and biased to connect the catch member main body 81 and the receiving seat 82, so that the tether 3 tightens the guide 2C and pulls the footboard 2 to the underside of the opening 1A, and the guide 2C forms a slight V-shape and remains stationary. When a harmful animal then steps down on the footboard 2, the left and right sides of the guide 2C are forcefully reversed, and the tether 3 jumps over the harmful animal's legs and shrinks. Then, in the same way as in the first embodiment, the connection of the connecting means 8 is released. Incidentally, the rectangular box-shaped frame 1 is merely an example, and the shape is not limited as long as there is a certain height between the guide 2C and the step 2 that sandwich the periphery of the opening 1A from above and below. EXAMPLES

[0040] A sixth embodiment of the device according to the present invention according to claims 2 and 7 will be described with reference to FIG. The top surface of the rectangular box-shaped frame 1 with no bottom surface has two circular openings and footboards 2 that fit into them, with a hoop 3 with a sound device 5 attached hung around the top end of each. As seen from the Z-axis, both footboards 2 are connected to a single connecting arm 2B on the underside of the frame 1, and are fixed to a first lever 72 at the center so that they can rotate integrally with the first lever support base 73 around an axis. The connecting means 8 is composed of a receiving seat 82 provided at the rear end of each of the two binding rings 3, and one catch member body 81 having a core receiving hole 81A. In this way, whichever step 2 the vermin steps down on, the trigger means operates in the same manner as in the first embodiment, and only the snaking ring 3 that the vermin steps on shrinks, and the snaking ring 3 that the vermin does not step on is pulled at the same time, but remains empty and does not shrink. The same procedure can be followed when three or more tethers 3 are provided.

[0041] As for the device of the present invention according to claim 3 or 4, and claim 7, similarly to this example, multiple steps 2 are integrally connected by a connecting arm 2B, so that no matter which step 2 a pest steps down on, the device can be operated in the same manner as in embodiment 2 or 3, respectively.
