Description

[Technical Field]

[0001] FIELD OF THE INVENTION The present invention relates to a trap wire device for use in a trap. [Background technology]

[0002] Patent Document 1 describes a trap invented by the inventors. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-182629 Summary of the Invention [Problem to be solved by the invention]

[0004] The spring-up traps described in Patent Document 1 and elsewhere capture animals by tying their legs with wire ropes. For example, if the animal is weak, such as a muntjac, even an ordinary person (without specialized knowledge or experience in capture) can handle the capture and disposal. However, if a strong animal, such as a deer or wild boar, becomes trapped and becomes violent, handling the animal after capture becomes a dangerous task. This type of work is difficult for ordinary people to perform.

[0005] SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a wire trap device suitable for capturing animals within an area that is accessible to the average person. [Means for solving the problem]

[0006] A first aspect of the present invention is a trap wire device used in a trap, the trap wire device comprising a wire rope device, a backstop, and a fastener, the tensile strength of which is lower than that of the wire rope device and the backstop, the wire rope device comprising a capture wire rope section and a spring section, the backstop having a first hole and a second hole through which the capture wire rope section passes, the capture wire rope section having one end connected to the spring section and a loop section at the other end, and the fastener fastening the second hole and the loop section together.

[0007] A second aspect of the present invention is the wire trap device of the first aspect, in which when the trap is activated, the spring portion extends and moves the return prevention device, tightening and capturing the animal's leg, and if the animal's leg applies a force to the fastener that exceeds its tensile strength, the fastener is cut.

[0008] A third aspect of the present invention is the trap wire device of the first or second aspect, wherein the anti-return device is a tying metal fitting.

[0009] A fourth aspect of the present invention is the trap wire device of the third aspect, which comprises a fixing portion, and the annular portion is formed by folding back the other end of the capture wire rope portion to form a ring-shaped portion, and fixing it to the middle of the capture wire rope portion by the fixing portion, and the fixing portion is a crimp-type sleeve, and the surface of the tether and the surface of the sleeve prevent damage to the legs of the trapped animal. [Effects of the Invention]

[0010] According to each aspect of the present invention, when a weak animal, such as a muntjac, is captured, the trap wire device maintains the trapped animal's legs in a tethered state. On the other hand, when a strong animal, such as a deer or wild boar, is captured, the fasteners are severed by the force of the trapped animal's legs, and the trapped state is not maintained. This makes it possible to capture only animals that are easy for an average person to handle.

[0011] Furthermore, according to the third aspect of the present invention, by using a binding metal fitting as the return prevention device, there is no need for a clamping prevention metal fitting. [Brief explanation of the drawings]

[Figure 2] This is a photograph of the entire prototype trap wire device. [Figure 3] This is an enlarged photograph of the fastener and its surroundings in the prototype of Figure 2. [Figure 4] This is a photograph of the trap activation device in the prototype. [Figure 5] This figure shows the state in which a columnar object 51 is fastened by a loop formed by a return prevention device 37 and a fastener 39 in the capture wire rope section 31.

DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, examples of the present invention will be described with reference to the drawings, but the present invention is not limited to the following examples. [Example]

[0014] 1 is a diagram showing an example of the configuration of a trap wire device 1 according to an embodiment of the present invention. The trap wire device 1 is used for a jump-up trap (snare trap).

[0015] Fig. 1(a) is a diagram showing the overall structure of the trap wire device 1. Figs. 1(b), (c), and (d) show the wire rope device 3, the anti-return device 5, and the fastener 7, respectively.

[0016] A spring trap captures an animal by tying its legs with a wire rope. While it is possible for an average person to handle a weak animal, such as a muntjac, it becomes more difficult when a powerful animal, such as a deer or wild boar, becomes violent.

[0017] The structure of the anti-return device 5 will be explained with reference to FIG. 1(c). The anti-return device 5 is a part that prevents the wire from loosening when the animal's leg is tied up. The anti-return device 5 is, for example, a metal tie. If the anti-return device 5 is a metal tie, there is no need for a fastening prevention metal. Furthermore, the surface of the metal tie can prevent serious damage (such as tearing) to the leg of an animal caught in a trap. The anti-return device 5 has a first hole 21 and a second hole 23.

[0018] 1(b), the structure of the wire rope device 3 will be described. The wire rope device 3 includes a capture wire rope portion 15, a fixing portion 17, a spring portion 13, and a fixing wire rope portion 11.

[0019] The capture wire rope section 15 is passed through the first hole 21 of the return prevention device 5. One end of the capture wire rope section 15 is connected to the spring section 13. The other end is provided with a loop section 19. In this example, a loop is formed by folding back the capture wire rope section 15, and this loop section 19 is fixed to the middle of the capture wire rope section 15 by the fixing section 17. This forms the loop section 19. The fixing section 17 is, for example, a crimped sleeve.

[0020] The structure of fastener 7 will be described with reference to FIG. 1(d). Fastener 7 fastens second hole 23 of anti-return device 5 to loop portion 19. Fastener 7 is, for example, a cable tie (e.g., Insulock (registered trademark)). A cable tie has a front and a back surface, with unevenness on the back surface. One end is called the tail, and is tapered toward the tip. The other end has a head. The head has a hollow into which the tail is inserted. The hollow has a claw. When the tail is inserted into the hollow of the head, the claw catches on the unevenness on the back surface, securing it in place. Therefore, the cable tie is fixed in a loop. By inserting the tail further, it can be tightened more.

[0021] When setting up a trap, the fixing wire rope section 11 is fixed to a tree or the like. The spring section 13 is set in the trap in a contracted state, so that the loop formed by the capture wire rope section 15 is in its largest state.

[0022] When an animal is caught in the trap and the trap is activated, the animal's leg is in the loop formed by the capture wire rope section 15. As the spring section 13 extends, the anti-return device 5 in the capture wire rope section 15 moves, making the loop formed by the capture wire rope section 15 smaller, tightening and capturing the animal's leg.

[0023] The tensile strength of the fastener 7 is smaller than the tensile strength of the wire rope device 3 and the anti-return device 5. When the fastener 7 is used to tie up an animal's leg, if the force applied by the animal's leg is smaller than the tensile strength, the fastener will not break and the tethered state will be maintained. On the other hand, when the fastener 7 is used to tie up an animal's leg, if the force applied by the animal's leg is larger than the tensile strength, the fastener will break. The anti-return device 5 is made of, for example, metal, and the fastener 7 is made of, for example, plastic.

[0024] The inventors have confirmed that by using a cable tie with a tensile strength of 180N as fastener 7, it is possible to capture a muntjac without fastener 7 being cut, and that if a deer or wild boar is captured, fastener 7 will be cut.

[0025] When trap wire device 1 captures a strong animal such as a deer or wild boar, the animal's feet apply force to fastener 7, causing fastener 7 to break, and the animal is no longer able to maintain its captured state, resulting in the animal being released. On the other hand, when trap wire device 1 captures a weak animal such as a muntjac, fastener 7 remains uncut, maintaining the trapped animal's feet in a tethered state. This allows only animals that can be captured by an average person to be easily handled.

[0026] A prototype of a trap wire created by the inventors will be described with reference to FIGS.

[0027] Figure 2 shows a photograph of the entire prototype trap wire device.

[0028] Figure 3 is an enlarged photograph of the vicinity of the fastener in the prototype of Figure 2. The specific configuration will be explained with reference to Figure 3(a). The capture wire rope portion 31 is passed through the first hole of the return prevention device 37. One end of the capture wire rope portion 31 is connected to the spring portion. The loop portion 35 is formed by folding back the other end and fixing it to the middle of the capture wire rope portion 31 with the fixing portion 33. The fastener 39 fastens the second hole of the return prevention device 37 and the loop portion 35 of the capture wire rope portion 31. Figure 3(b) is a photograph of Figure 3(a) taken from a different angle.

[0029] FIG. 4 is a photograph of a prototype trap activation device (see Patent Document 1).

[0030] The configuration of the trap activation device will be explained with reference to Figure 4(a). The trap activation device comprises a step and a cylindrical pipe. The step has two arms. The arms are U-shaped, and their ends are rotatably supported by the step. The step is placed on the pipe with the arms spread out.

[0031] 4(b), the state in which the capture wire rope section 31 is installed in the trap operating device will be described. The capture wire rope section 31 is hung on the outside of the arm with the spring section compressed (i.e., with the loop formed by the return prevention device 37 and the fastener 39 in the capture wire rope section 31 at its widest).

[0032] When an animal steps on the step, the step falls into the pipe, causing the U-shaped center of the arm to spring up. As the arm springs up, the capture wire rope part 31 attached to the outside springs up onto the foot of the animal that stepped on the step. As the spring part stretches, the loop formed by the return prevention device 37 and the fastener 39 in the capture wire rope part 31 becomes smaller, tightening and capturing the animal's foot.

[0033] FIG. 5 shows the state in which the post 51 is fastened by the loop formed by the anti-return device 37 and the fastener 39 in the capture wire rope section 31. The post 51 corresponds to the leg of an animal caught in a trap. In reality, the legs of animals caught in traps are thin. The wire rope of the capture wire rope section 31 is thin, and may injure the animal's leg or even break. The presence of the surface of the anti-return device 37 and the surface of the fixing section 33 makes it possible to capture the animal while preventing injury to the animal's leg.

[0034] Figure 6 shows the state in which the fastener 39 has been cut. As shown in Figure 6(a), if the foot of an animal caught in a trap applies a force greater than the tensile strength of the fastener 39, the fastener 39 will be cut. This causes the anti-return device 37 and the loop portion 35 to separate. As a result, the trap wire device will no longer be able to maintain the state in which the animal's foot is captured. Figure 6(b) is a close-up photograph of the cut fastener 39.

[0035] 7 is a photograph of the new fastener 41. The new fastener 41 is a cable tie.

[0036] Figure 8 is a diagram illustrating the process of fastening the anti-return device 37 and the annular portion 35 with a new fastener 41. The tail of the new fastener 41 is passed through the second hole of the anti-return device 37 and the annular portion 35, and inserted into the hollow of the head. Figure 8(a) shows the state in which the tail of the new fastener 41 has been inserted into the hollow of the head. Figure 8(b) is an enlarged photograph.

[0037] Figure 9(a) shows the state in Figure 8 where a new fastener 41 has been fastened. This allows the new fastener 41 to fasten the anti-return device 37 and the annular portion 35. Figure 9(b) shows the state where a portion of the tail has been cut off. The portion of the tail that is not necessary for fastening the anti-return device 37 and the annular portion 35 has been cut off.

[0038] In the present invention, the annular portion may be formed by utilizing a capture wire rope portion such as a sleeve as described above, or may be formed by utilizing a part such as a ring (a ring-shaped member, the shape of which may be, for example, a circle, an ellipse, a polygon, etc.).
