Description

[Technical field]

[0001] The present invention relates to a snare trap. [Background technology]

[0002] For example, a tying trap disclosed in the following Patent Document 1 is known as a tool used to capture vermin. This tying trap is composed of a step body, a pair of straps, an installation frame, and a tying wire with a fastening loop formed on one end. When a vermin's foot steps on the step body, the step body lowers and contacts the bottom surface of the installation frame. At this time, each strap rotates, and the tying loop of the tying wire attached to each strap is released, and the tying loop shrinks due to the elastic force of a coil spring member attached to the tying wire, tying the vermin's foot. This makes it possible to capture the vermin. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3177935 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the conventional snare traps described above have the following problems to be solved. Specifically, conventional snare traps may mistakenly capture not only animals designated as harmful animals such as wild boars and Japanese deer, but also bears that are not designated as harmful animals and are protected or require special permission to be captured. In this case, in some areas, when a bear is mistakenly captured, it is mandatory by ordinance to inject anesthesia into the bear, release it from the snare trap, and release it into the forest after it has recovered. For this reason, in such areas, there is a problem that a large cost is incurred due to the mistaken capture of a bear and it is difficult to ensure the safety of the trapper. As a countermeasure, there is a method of constructing a snare trap from a material with low strength that can be destroyed by the force of a mistakenly captured bear, but with such a snare trap, there is a problem that it is difficult to capture the harmful animal itself.

[0005] Therefore, the object of the present invention has been made in consideration of such problems, and is to provide a snare trap that can reliably capture the target harmful animal while reliably preventing the erroneous capture of a bear, which is not designated as a harmful animal. [Means for solving the problem]

[0006] In order to solve the above problems, one aspect of the binding trap of the present invention comprises an inner cylindrical body 11 formed from a tapered portion 21 and a tubular portion 22 connected to the tapered portion 21 extending downward from the peripheral edge of the opening, and an outer cylindrical body 12 having a plurality of holding claw portions 40 formed at a predetermined interval on the outer peripheral edge of the upper end and holding trap loops 71 that constitute a wire member biased by a spring 73 and used to bind the legs of an animal to be captured, and is characterized in that a wire release portion 50 having at least a pedal 51 is disposed on the lower end side of the inner cylindrical body 11, and the hold of the trap loops 71 by the holding claw portions 40 is released in conjunction with the load on the pedal 51.

[0007] Another aspect of the snare trap of the present invention is that when a downward force is applied to the pedal, it rotates around a fulcrum, causing a hook formed on one end of the pedal lever to actuate inward, causing the wire to come off the holding claw portion 40 and be tied to the leg of the animal to be captured.

[0008] Another aspect of the tie-down trap of the present invention is characterized in that a cover member 14 having an insertion hole 16 formed in the center and having cuts 18 formed radially from the insertion hole 16 as the center is placed so as to cover the upper surface of the inner cylindrical body 11.

[0009] In addition, another side of the binding snare according to the present invention is provided with a wire slippage prevention member 80, which is composed of a convex plate-like member 84 consisting of a convex portion 82 and a base portion 83 in a plan view, and a vertical plate-like member 85 extending vertically from the base portion 83, A substantially rectangular receiving member 90 is placed on a portion of the upper edge surface of the tapered portion 21, and when the trap loop is held by the holding claw portion, the convex plate member 84 of the wire slippage prevention member 80 is inserted between the upper edge surface of the tapered portion 21 and the receiving member 90. Effect of the Invention

[0010] The snare trap of the present invention can reliably capture the target harmful animal while preventing the mistaken capture of a bear, which is not designated as a harmful animal. [Brief description of the drawings]

[Diagram 2] FIG. 13 is a diagram showing a state in which the wire is held by the wire holding claws. [Diagram 3] FIG. 13 is a diagram showing a state in which the spring of the wire member has been released. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] <Embodiment 1> Hereinafter, a first embodiment of the binding trap according to the present invention will be described with reference to the drawings. Note that the embodiment shown below is an example of the present invention, and the present invention is not limited to the following embodiment, and various configurations can be adopted.

[0013] FIG. 1 is an overall perspective view of a tie-down trap according to the present invention.

[0014] The snare trap 1 is a trap for capturing harmful animals, and as shown in FIG. 1, is configured to include a cylindrical member 10, a wire member 70, and a cover member 14. [Cylindrical member 10] The cylindrical member 10 is comprised of an inner cylindrical body 11 and an outer cylindrical body 12, and is buried in a hole provided in the ground.

[0015] <Inner cylindrical body 11> The inner cylindrical body 11 is formed of a ring-shaped flange 20 forming an opening periphery, a tapered portion 21 having a slope 23 formed downward from the flange 20, and a cylindrical portion (the inner diameter of the cylindrical portion is about 75 mm) 22 connected to the lower end of the tapered portion 21. In the example of FIG. 1, the tapered portion 21 is formed with a slope 23 formed at a predetermined angle from the upper peripheral portion of the tapered portion 21 toward the upper opening edge of the cylindrical portion 22, and has a function of guiding the legs of the animal downward. A notch 61 is formed in a part of the flange 20 of the inner cylindrical body 11. By forming this notch 61, a hook portion 55 constituting a wire release portion 50 described later can move up and down within the notch 61. Through holes 42 are formed at multiple locations (six locations in the example of FIG. 1) on the peripheral surface of the flange 20. The number of through holes 42 is not limited to six, and it is sufficient that there are at least two or more. The function of the through-hole 42 will be described later.

[0016] When an animal's leg (e.g., a hoof) enters the upper opening of the inner cylindrical body 11, the leg slides down the slope of the tapered portion 21 and is guided to the upper opening of the cylindrical portion 22. Note that, as long as the animal's leg can slide down, the shape may be other than the slope, for example, a shape in which vertical and slope surfaces are alternately formed. Note that the inner diameter of the cylindrical portion is preferably about 75 mm so that when a wild boar, a Japanese deer, or the like (ungulates) having a "hoof" with a relatively small sole area steps on it, the "hoof" can reach the pedal 51 described below. The inner cylindrical body 11 is formed of a resin material such as polyvinyl chloride, but is not limited to this as long as it has a predetermined strength.

[0017] <Outer cylindrical body 12> The outer cylindrical body 12 has a function of accommodating the inner cylindrical body 11 and holding a trap loop (trap portion) 71 constituting a wire member 70 for tying up the legs of an animal guided from the upper end opening of the inner cylindrical body 11. A notch 60 is formed on the upper end edge surface of the outer cylindrical body 12 at a position corresponding to a notch 61 formed on the flange portion 20 of the inner cylindrical body 11. By forming this notch 60, a hook portion 55 constituting a wire release portion 50 described later can move up and down within the notch 60. A plurality of through holes (not shown) are formed on the upper end edge surface of the outer cylindrical body 12 (six in the example of FIG. 1) through which screws 41 for fixing the inner cylindrical body 11 after accommodating the inner cylindrical body 11 are inserted. The number of the screws 41 and the through holes (not shown) is not limited to six, and may be the same as the number of the above-mentioned through holes 42, and may be at least two or more.

[0018] The inner cylindrical body 11 is fixed to the outer cylindrical body 12 as follows. After the inner cylindrical body 11 is accommodated inside the outer cylindrical body 12, screws 41 are inserted through through holes 42 formed in the flange 20 of the inner cylindrical body 11, through holes (not shown) formed in the upper edge surface of the outer cylindrical body 12, and through holes 43 formed in wire holding claws 40 described later, and the inner cylindrical body 11 is screwed and fixed to the upper edge surface 44 of the outer cylindrical body 12. In the embodiment, an example of screwing has been described for fixing the inner cylindrical body 11 to the outer cylindrical body 12, but the lower surface of the flange 20 of the inner cylindrical body 11 and the upper edge surface 44 of the outer cylindrical body 12 may be bonded with an adhesive or welded to be fixed.

[0019] 2, the outer cylindrical body 12 has an inner diameter large enough to accommodate the inner cylindrical body 11. Specifically, as shown in the figure, the inner diameter of the outer cylindrical body 12 is formed into a cylindrical shape that is slightly larger than the outer diameter of the opening (upper edge of the tapered portion 21) of the inner cylindrical body 11. In this case, the outer cylindrical body 12 is formed of the same material as the inner cylindrical body 11, but is not limited to this as long as it has a predetermined strength.

[0020] A wire release portion 50 is disposed on the lower end side of the outer cylindrical body 12 and inside the cylindrical portion 22 of the inner cylindrical body 11. A plurality of wire holding claws 40 (six in the example of FIG. 1) that hold a trap loop (trap portion) 71 are formed at predetermined intervals on the outer peripheral edge at the upper end of the outer cylindrical body 12.

[0021] The wire release unit 50 is configured to include a pedal 51, a connection member 52 having one end connected to the pedal 51, and a rod-shaped release member 54 having one end connected to the connection member 52. A hook portion 55 is formed at the other end of the rod-shaped release member 54. A through hole 56 is formed near the middle portion of the connection member 52 to allow the rod-shaped fulcrum member 53 to pass through. Both ends of the rod-shaped fulcrum member 53 are fixed to the inner circumferential surface of the cylindrical portion 22 using a fixing member (not shown) such as a screw. The hook portion 55 has an L-shape with the end of the hook portion 55 facing upward. The connection member 52 is rotatable in the axial direction with the rod-shaped fulcrum member 53 as a fulcrum. That is, when the weight of the animal's leg is applied to the upper surface of the pedal 51, the hook portion 55 formed at the other end of the connection member 52 rotates (moves) toward the upper direction of the upper peripheral edge portion of the outer cylindrical body. The connection member 52 and the rod-shaped fulcrum member 53 may be integrally formed, or may be connected to each other by a screw or the like.

[0022] [Wire member 70] The wire member 70 is well known and therefore will not be described in detail here. The wire member 70 is configured to include at least a trap loop (trap portion) 71, a spring 73, and a spring case (not shown).

[0023] The wire including the trap loop 71 is, for example, made of a wire with a diameter of 4 mm or more. Also, at one end of the wire, a trap loop 71 is formed which can be expanded or contracted by passing the other end through a loop (not shown) provided at the one end. In addition, the inner diameter of the wire including the trap loop 71 held by the wire holding claw 40 is regulated by law to be 120 mm or less in principle (as an exception, in Nagano Prefecture, it may exceed 120 mm).

[0024] The spring 73 is an example of a biasing member, and generates a biasing force that contracts the trap loop 71 with the wire inserted, as shown in FIG. 1. The spring case (not shown) is cylindrical and houses the spring 73 in a compressed state. The trap loop 71 is held by the wire holding claw 40 with the spring 73 compressed to generate a biasing force. The operation of the hook portion 55 and the wire member 70 after the animal's leg is guided will be described later. The form (structure) of the wire member 70 is not limited to the above-mentioned form, so long as it has the above-mentioned function, i.e., the function of generating a biasing force that contracts the trap loop.

[0025] [Cover member 14] 1, the cover member 14 is a disk-shaped plate member that is placed on the upper surface of the inner cylindrical body 11 so as to cover the trap loop 71 held by the wire holding claws 40 of the inner cylindrical body 11. The cover member 14 has a function of hiding (camouflaging) the binding trap 1 by placing soil, dead leaves, etc. on it. The cover member 14 is made of a flexible material (for example, a thin resin plate).

[0026] The cover member 14 has an insertion hole 16 formed in the center, and cuts 18 formed radially from the insertion hole 16. In this case, the length of the cuts 18 can be determined to an appropriate size depending on the type of the animal to be captured, but it is preferable to determine the length to be slightly shorter than the diameter of the cylindrical portion 22 of the inner cylindrical body 11 and shorter than the length of the legs of the bear, which is the animal to be protected. The shape of the cover member 14 is not limited to a disk shape, and may be, for example, a polygonal shape or a square shape. In addition, a side plate (not shown) extending vertically downward from the periphery of the cover member 14 may be formed to prevent the cover member 14 from being displaced. In addition, as long as the cuts 18 are radial, they may be radial with straight cut lines as shown in FIG. 1, or may be radial with wavy lines, curved lines, or the like.

[0027] The legs of animals such as wild boars, Japanese deer, and bears are guided into the slits in the cover member 14, and then the wild boars and Japanese deer (harmful animals: see Figure 5) are reliably captured, while bears (animals to be protected) which are plantigrade animals with large sole areas and walk using the entire sole of their feet, are not captured. This will be described later in the explanation of the operation of the snare trap 1.

[0028] [Setting Binding Trap 1] The installation of the snare trap 1 will now be described.

[0029] First, we will explain how to set up (set) the noose trap 1. First, select a location that is likely to be a passageway for the animal to be captured as the trap location. Then, dig a hole large enough to bury the cylindrical member 10 in the ground at the trap location.

[0030] Next, the binding trap 1 is assembled. First, the inner cylindrical body 11 is inserted inside the outer cylindrical body 12. Next, the screw of the spring stopper (not shown) is loosened to make it movable, and then the trap loop 71 is adjusted so that the loop diameter of the trap loop 71 is larger than the outer diameter of the outer cylindrical body 12. Next, as shown in FIG. 2, the trap loop 71 is wound while being held between the wire holding claw 40 of the outer cylindrical body 12 and the upper peripheral edge of the inner cylindrical body 11. At this time, the trap loop 71 is held by placing a part of the trap loop 71 on the L-shaped part of the hook part 55.

[0031] Next, the spring 73 is compressed and housed in the spring case by bringing the spring case close to the cap 75, and then the spring stopper (not shown) is moved to the base end (the lower end in the figure) of the spring case. As a result, as shown in Figure 3, the biasing force generated by the compression of the spring 73 acts on the trap loop 71 in a direction to reduce the trap loop 71, and the trap loop 71 is maintained in a state in which it is tightened inwardly against the upper peripheral edge of the inner cylindrical body 11 by the biasing force of the spring 73.

[0032] Next, the cylindrical member 10 is buried in a hole dug in the ground, and then the cover member 14 is placed on the outer cylindrical member 12 so as to cover the trap loop 71 wound around the periphery of the outer cylindrical member 12. Next, soil, dead leaves, etc. are placed on the cover member 30 to camouflage it. Next, the other end 71b of the wire 71 (see FIG. 1) is tied to a standing tree. This completes the installation of the tying trap 1.

[0033] [Activity of Binding Trap 1] The operation of the snare trap 1 will now be described.

[0034] For example, when a target animal (vermin) such as a wild boar or a Japanese deer (ungulate) having a hoof with a relatively small area on the underside steps on the cover member 14 of the snare trap 1 with its hoof (leg), the upper surface of the cover member 14 divided by the cuts 18 elastically deforms toward the inside of the inner cylindrical body 11, and the insertion hole (see FIG. 1) in the center of the upper surface of the cover member 14 expands (increases in diameter). Therefore, the leg of the target animal is guided to the center of the cover member 14 and passes through the insertion hole, and is reliably inserted into the interior 11a of the inner cylindrical body 11.

[0035] When the pedal 51 arranged below the interior 11a of the inner cylindrical body 11 is stepped on by the leg (hoof) of the animal to be captured, the connecting member 52 rotates counterclockwise in the axial direction with the rod-shaped fulcrum member 53 as the fulcrum (axis). Then, the rod-shaped release member 54 above the rod-shaped fulcrum member 53 moves upward, and the hook portion 55 also moves upward. When the hook portion 55 moves upward, the trap loop 71 held between the wire holding claw 40 and the upper peripheral portion of the outer cylindrical body 12 comes off, and the trap loop 71 shrinks due to the biasing force of the spring 73.

[0036] Therefore, it is possible to reliably bind target animals (vermin) such as wild boars and Japanese deer (ungulates) which have hooves with a relatively small underside area, making it possible to reliably capture the target animals.

[0037] On the other hand, when a bear (animal to be protected), which is a plantigrade with a large sole area and walks using the entire sole, steps on the cover member 14 of the snare trap 1 with its legs, the upper surface of the cover member 30 divided by the cut 18 (see FIG. 1) elastically deforms toward the inside 11a of the inner cylindrical body 11, but the legs are placed on the upper opening of the cylindrical part 22 of the inner cylindrical body 11 and do not penetrate further downward. This is because the diameter of the upper opening of the cylindrical part 22 is narrower than the sole area of ​​the bear's legs. Therefore, the trap loop 71 does not shrink, and the animal to be protected leaves the area without the bear's legs being captured by the snare trap 1. This prevents the wire from being tied to the bear's legs by the trap loop 71, and prevents the bear from being captured by mistake.

[0038] <Embodiment 2> Hereinafter, the second embodiment of the tie-down trap will be described with reference to the drawings. Since the second embodiment is the same as the first embodiment except that a wire-slip prevention member 80 and a receiving member 90 into which the wire-slip prevention member 80 is inserted are added to the first embodiment, only the different parts will be described and the description of the similar parts will be omitted. Also, the same reference numbers may be used for similar parts when it is not necessary to distinguish them.

[0039] As shown in FIG. 1 (see the partially enlarged perspective view in FIG. 1), the wire slippage prevention member 80 is composed of a convex plate member 84 consisting of a convex portion 82 and a base portion 83 in a plan view, and a vertical plate member 85 extending vertically upward from the base portion 83. The receiving member 90 is substantially rectangular as shown in FIG. 1, and is fixed to a part of the upper edge surface of the tapered portion 21 of the inner cylindrical body 11. A gap is formed between the upper edge surface of the tapered portion 21 and the receiving member 90, which is large enough to insert the convex portion 82 of the wire slippage prevention member 80. The receiving member 90 is fixed to the upper edge surface of the tapered portion 21 using a screw 91 and a washer (not shown because it is formed on the back side). After the wire 71 is wound around the wire while being held between the wire holding claws 40 and the upper peripheral edge of the outer cylindrical body 12, the convex portion 82 is inserted into the wire removal prevention member 80, whereby the wire of the trap loop 71 is abutted against the underside of the convex plate member 84, thereby preventing the trap loop 71 from coming off in the upward direction.

[0040] In the above-mentioned second embodiment, the wire detachment prevention member 80 is provided at one location on the upper edge surface of the tapered portion 21 of the inner cylindrical body 11, but the wire detachment prevention member 80 may be provided at two or more locations on the upper edge surface of the tapered portion 21 of the inner cylindrical body 11. In this case, it is possible to more reliably prevent the trap loop 71 from detaching in the upward direction.

[0041] The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit and scope of the present invention. [Explanation of symbols]
