Description

[Technical field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates to a snare trap for capturing vermin, a tread piece for a snare trap, and a method for assembling a snare trap. [Background technology]

[0002] For example, a pest trapping device as disclosed in the following Patent Document 1 is commonly used as a snare trap for capturing pests. The pest trapping device of Patent Document 1 is composed of a cylindrical base having side walls erected around its periphery, a wire holder engaged and fixed to the side walls of the cylindrical base, a step forming the bottom of the wire holder, left and right semicircular wire holders each having both ends pivotally supported by the side walls of the step and biased to stand up on the left and right, a loop of a capture wire surrounding the semicircular outer periphery of the left and right wire holders when the left and right wire holders are in a laid-down state, and a wire diameter reduction biasing mechanism that pulls the base of the loop of the wire surrounding the left and right wire holders to bias the loop to reduce its diameter.

[0003] In this way, in the general snare trap described above, the footboard is moved up and down within the cylindrical base to release the capture wire from the left and right wire holders and tighten the legs of the pest, thereby capturing the pest. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 2022-65605 Summary of the Invention [Problem to be solved by the invention]

[0005] However, while this type of snare trap only requires a short distance for the step to move up and down, it can become inoperable if a foreign object gets caught under the step. Also, because the gap between the inner periphery of the cylindrical base and the outer periphery of the step is narrow, if a pest trap with this structure is used in winter, the step will freeze inside the cylindrical base and will no longer function.

[0006] Furthermore, this type of tie-down trap is expensive because it has many parts for operating the step plate as described above.

[0007] Therefore, the present disclosure provides a tie-down trap that can be reliably operated with a simple configuration, a step piece for the tie-down trap, and a method for assembling the tie-down trap. [Means for solving the problem]

[0008] In order to solve the above problems, according to the present disclosure, there is provided a binding trap comprising a tubular member, a footplate portion attached to the tubular member and extending from the outside of the tubular member toward the center of the tubular member and overlapping a hole in the tubular member, a plurality of footplate pieces having retaining portions connected to the outside of the tubular member so as to bend from the outer periphery side of the tubular member of the footplate portions, and a wire rope having a ring-shaped portion that is hung on the outer periphery of the retaining portions of the footplate pieces on the outer periphery of the tubular member to tighten the footplate pieces to the outer periphery of the tubular member.

[0009] A method for assembling the above-mentioned tie-down trap, comprising: arranging a plurality of step pieces so that the retaining portion faces upward and is located outside the tubular member; and arranging the tubular member on the step portions of the step pieces; The method for assembling a tie-down trap may include fastening the holding portion of the footboard piece from the outer periphery of the tubular member with the wire rope.

[0010] The step piece may be attached to a tubular member for a tie-down trap, and when attached to the tubular member, the step piece may have a step portion that extends from the outside of the tubular member toward the center of the tubular member and is overlapped with a hole in the tubular member, and a retaining portion that is connected to the outside of the tubular member by bending the step portion from the outer periphery side of the tubular member.

[0013] Hereinafter, an embodiment of a tie-down trap, a step piece for the tie-down trap, and an assembly method for the tie-down trap will be described with reference to the drawings. The following description will focus on the main components of the tie-down trap and the step piece, but the tie-down trap and the step piece may have components and functions that are not shown or described. The following description does not exclude components and functions that are not shown or described.

[0014] First Embodiment <Outline of the trap> First, an outline of the configuration of the binding trap in the first embodiment will be described. Fig. 1 is a perspective view showing one embodiment of the binding trap to which the present technology is applied. Fig. 2 is a perspective view showing a detailed configuration of a step piece in the binding trap of the first embodiment.

[0015] As shown in FIG. 1, the binding trap 1 is mainly composed of a tubular member 10, a plurality of step pieces 20, and a wire tightening mechanism 30. The tubular member 10 is made of, for example, plastic or metal (iron or aluminum) in a tubular shape with an outer diameter D1. As an example, the tubular member 10 can be inexpensively and easily manufactured by dividing a pipe with a circular cross section, such as an inexpensive polyvinyl chloride pipe for piping, into a predetermined height (in other words, width in the length direction). Such pipes are also widely used in conventional binding traps as described above, and the pipes already in use can be used as the tubular member 10. The tubular member 10 may be formed using a pipe with a cross section of another polygon, such as a square or hexagon, other than a circular cross section.

[0016] 1, a step piece 20 is attached to one end 11 of the tubular member 10 in an overlapping manner, so that a part of the step piece 20 is disposed along the outer circumferential surface 12. The tubular member 10 may also be provided with a connection hole 12a at the other end 13 side for connection to the step piece 20, as described below. As shown in the figure, the connection hole 12a is formed as a through hole that penetrates the tubular member 10 in the thickness direction from the outer circumferential surface 12 to the inner circumferential surface.

[0017] The step piece 20 is made of plastic or metal and has an L-shaped cross section. The step piece 20 may be formed by injection molding or 3D printing of plastic, or by bending a metal plate. As shown in FIG. 2, the step piece 20 has a step part 21, a holding part 22, and a connecting part 23. The step part 21 extends from the outside of the tubular member 10 toward the center of the tubular member 10 and is overlapped with a hole on one end 11 side of the tubular member 10. In this embodiment, as shown in FIG. 1, six step pieces 20 are attached to the tubular member 10 at equal intervals, so that the holes on one end 11 side are covered with the six step parts 21, and there are equal gaps between them. It is preferable that this gap is smaller than the size of the foot of the harmful animal to be captured. The holding part 22 is connected so as to be bent from the outer periphery side of the tubular member 10 of the step part 21 on the outside of the tubular member 10. The connection portion 23 connects the footboard portion 21 and the holding portion 22 with a curved cross-sectional shape.

[0018] 1, the wire tightening mechanism 30 is mainly composed of a wire rope 31, a spring 32, a spring case 33, and a cap 34. The wire tightening mechanism 30 can fix the spring case 33 at any position on the wire rope 31 with a spring stopper (not shown), thereby putting the spring 32 in a predetermined compressed state between the spring case 33 and the cap 34.

[0019] The wire rope 31 is made of a metal wire having a diameter of, for example, 4 to 5 mm or more. The wire rope 31 has a ring portion 31a at one end thereof that functions as a trap for fastening the legs of vermin. The ring portion 31a can be expanded or contracted by forming one end of the wire rope 31 into a loop and passing the other portion through the loop. A contraction prevention stopper (not shown) may be provided on the ring portion 31a to prevent the ring portion 31a from being contracted below a predetermined diameter. The ring portion 31a is wound around and fastened to the outer periphery of the holding portion 22 of the step piece 20 in the assembled state of the binding trap 1, thereby fixing the step piece 20 to the tubular member 10. In this case, the ring portion 31a is wound around and fastened by being hung on the outer periphery of the holding portion 22 of the step piece 20 on the outer circumferential surface 12 of the tubular member 10. As a result, the ring portion 31a fastens the step piece 20 to the outer periphery of the tubular member 10.

[0020] A cap 34, a spring 32, and a spring case 33 are inserted in this order adjacent to the annular portion 31a of the wire rope 31. The other end of the wire rope 31 has a fixable structure (not shown) that can be fixed to a fixed object such as a tree. Note that a swivel (not shown) that can be rotatably connected to the wire rope 31 may be provided midway along the wire rope 31.

[0021] The spring 32 is housed in a compressed state between the cap 34 and the spring case 33 when the tie-down trap 1 is in an assembled state. This allows the annular portion 31a of the wire rope 31 to be shortened via the cap 34 when the tie-down trap 1 is operated. The spring case 33 is made of plastic or metal and has a cylindrical inner shape capable of housing the spring 32, and is configured so that it can be fixed at any position on the wire rope 31 by a spring stopper (not shown) on the other end side of the wire rope 31 (not shown).

[0022] Such a wire fastening mechanism 30 is also widely used in conventional binding traps as described above, and the already used wire fastening mechanism 30 can be used in combination with the tubular member 10. In this way, since the particularly novel component in the binding trap 1 is the footplate piece 20, the already used tubular member 10 and wire fastening mechanism 30 can be used to make the binding trap 1 by simply preparing the footplate piece 20, and the binding trap 1 can be used inexpensively.

[0023] With the above-mentioned configuration, in the binding trap 1 of this embodiment, when any of the step pieces 20 rotates, the state of fastening the tubular member 10 via the holding portion 22 of the step piece 20 is released. As a result, the wire rope 31 moves to one end portion 11 side of the tubular member 10 (upper side in Fig. 1), from a position on the outer periphery of the tubular member 10 to an upper position in Fig. 1, and the wire rope 31 can be operated to reduce its diameter. This allows the loop portion 31a of the wire rope 31 to fasten and capture the legs of a harmful animal.

[0024] <Stepping piece configuration> Next, the configuration of the step plate piece 20 will be described in detail with reference to FIG. 2. The step plate portion 21 constituting the step plate piece 20 is formed to have a length L1 and a thickness T1 as shown in the figure. This length L1 is less than half the diameter D1 of the outer circumference of the tubular member 10. This allows the step plate pieces 20 attached to the tubular member 10 to operate without interfering with each other. The step plate portion 21 has a base end portion 211 with a width W1, a reduced diameter portion 212 whose width narrows toward the tip side, and a tip portion 213 that is chamfered to a predetermined degree. The base end portion 211 is overlapped with one end portion 11 of the tubular member 10, so that the step plate piece 20 is supported by the tubular member 10. As a result, the base end portion 211 becomes a fulcrum that is supported by the end portion 11 when the step plate piece 20 rotates.

[0025] The reduced diameter section 212 is formed such that the width W1 of the base end 211 narrows toward the tip end 213 (in other words, toward the tip that faces the center of the tubular member 10) in a plan view. More specifically, the reduced diameter section 212 is configured such that the angle between two sides that define the width is smaller than the angle obtained by dividing 360 degrees by the number of footplate pieces 20 used. For example, in this embodiment, since six footplate pieces 20 are used, the reduced diameter section 212 is configured such that the angle between two sides that define the width is 60 degrees or less.

[0026] The holding part 22 is connected to the base end 211 side of the footboard part 21 via the connecting part 23 so as to bend. In this embodiment, the holding part 22 is arranged so as to bend at a right angle to the footboard part 21. The footboard piece 20 is formed with a connecting hole 221 for connecting to the tubular member 10. As a result, in the binding trap 1, the connecting hole 221, which is the first connecting part in the footboard piece 20, and the connecting hole 12a, which is the second connecting part in the tubular member 10, are provided, and these can be connected with a string-like connecting tool 40 (shown as a broken line in FIG. 1). With this configuration, it is possible to prevent the footboard piece 20 from flying away due to the tightening action of the wire rope 31, and to prevent the footboard piece 20 from being lost.

[0027] Furthermore, by combining the connecting hole 221 with the connecting tool 40, the connecting tool 40 can function as a protrusion facing outward in the holding part 22. This allows the connecting hole 221 to function as a step part for preventing the wire rope 31 from slipping out downward. The holding part 22 can have a height H1 of about 15 to 20 mm, for example. This is to provide a height H2 sufficient for hanging the wire rope 31 when the position of the connecting hole 221 is taken into consideration.

[0028] <How to Assemble a Snare Trap> A method for assembling the tie-down trap 1 having the above-mentioned configuration will be described. Fig. 3 is a perspective view showing a step in the method for assembling the tie-down trap. Fig. 4 is a perspective view showing a step in the method for assembling the tie-down trap following Fig. 3. In this embodiment, a method for assembling the tie-down trap 1 using the assembly jig 100 will be described, but the tie-down trap 1 may be assembled without using the assembly jig 100.

[0029] First, the configuration of the assembly jig 100 will be described. As shown in Fig. 3(A), the assembly jig 100 is configured by assembling and fixing six jig pieces 110 to a flat jig plate 120. The six jig pieces 110 are assembled to form a predetermined circular shape, and are configured to a size that allows the six step pieces 20 and the tubular member 10 to be housed inside in a predetermined assembled state. The six jig pieces 110 and the jig plate 120 may be integrally formed. With this configuration, the assembly jig 100 can be positioned in a predetermined relative position for assembling the step pieces 20 to the tubular member 10.

[0030] Specifically, the jig piece 110 is configured to have an arc shape as a whole, including an outer periphery base 111 and an inner periphery protrusion 112. The outer periphery base 111 is formed with a first inner periphery surface 111a in which both ends of the inner periphery protrusion 112 are cut out, and a second inner periphery surface 111b in a position where the inner periphery protrusion 112 is overlapped. The first inner periphery surface 111a is formed in a flat shape that functions as a positioning portion 130 for positioning the holding portion 22 side of the footplate piece 20 at a predetermined position when two adjacent jig pieces 110 are assembled, since the first inner periphery surface 111a is recessed from the inner periphery protrusion 112 toward the outer periphery. The second inner periphery surface 111b is formed in a curved shape that can hold the tubular member 10 at a predetermined position when the six jig pieces 110 are assembled.

[0031] Both circumferential ends of the inner peripheral protrusion 112 are notched, so that the inner peripheral protrusion 112 protrudes inward from the outer peripheral base 111. As a result, the side surface 112a of the inner peripheral protrusion 112 and the first inner peripheral surface 111a of the outer peripheral base 111 form a positioning portion 130 that positions the footplate piece 20. The width W2 of the positioning portion 130 is configured to be slightly larger than the width W1 of the footplate portion 21 (more specifically, the base end portion 211) so that the footplate piece 20 can be arranged and positioned.

[0032] On the other hand, the thickness T2 of the jig piece 110 is preferably equal to or less than the height from the footplate portion 21 to the connection hole 221 so that the annular portion 31a of the wire rope 31 can be hung on the footplate piece 20, as described below. Also, the thickness T3 of the inner peripheral protrusion 112 is configured to be equal to or less than the thickness T1 of the footplate portion 21. This allows the footplate portion 21 to be assembled in a state of contact with the tubular member 10.

[0033] In a method for assembling the binding trap 1 using such an assembly jig 100, first, the assembly jig 100 is prepared as shown in Fig. 3(A). Next, as shown in Fig. 3(B), a plurality of step pieces 20 are arranged so that the holding parts 22 face upward and are positioned outside the tubular member 10. In this case, the six step pieces 20 are aligned with the six positioning parts 130, respectively, and the outer peripheral surface of the holding part 22 is brought into contact with the first inner peripheral surface 111a of the jig piece 110. This allows the tubular member 10 to be arranged inside the six holding parts 22. At this time, the six step pieces 20 are arranged radially.

[0034] 4(A), the tubular member 10 is placed on the step portion 21 of the step piece 20 and inside the retaining portion 22. In this case, one end portion 11 of the tubular member 10 is brought into contact with the step portion 21 of the step piece 20 with one end portion 11 facing downward, so that the six step pieces 20 and the tubular member 10 can be appropriately positioned.

[0035] Finally, as shown in FIG. 4(B), the holding part 22 of the footplate piece 20 is fastened by the annular part 31a of the wire rope 31 from the outer periphery of the tubular member 10. In this case, with the annular part 31a hanging on the outer periphery of the holding part 22 of the footplate piece 20, the spring case 33 is pushed into the annular part 31a side to reach a desired fastening state, and then the position of the spring case 33 relative to the wire rope 31 is fixed by a spring stopper (not shown). This completes the assembly of the binding trap 1. Thus, according to the assembly method of the binding trap 1 in this embodiment, the binding trap 1 can be assembled simply by stacking the components of the binding trap 1 on the assembly jig 100, so that the binding trap 1 can be easily assembled and installed.

[0036] <How the Binding Trap works> Fig. 5 is a cross-sectional view explaining the operation of the noose trap. Fig. 6 is a perspective view explaining the operation of the noose trap. (A) to (C) in each figure show the same operation state. Here, the operation is explained when a vermin gets caught in the noose trap 1 set on the ground, and its foot 300 is tightened by the wire rope 31 to capture it.

[0037] First, as shown in Figures 5(A) and 6(A), the noose trap 1 is set in a pit dug in the ground anywhere in the mountains, etc. In this case, the noose trap 1 is set so that the footboard piece 20 faces upward. The other end of the wire rope 31 is fixed to a fixed object (e.g., a tree) not shown. Also, the noose trap 1 may be hidden by covering it with camouflage material 400 such as fallen leaves so that it is not found by harmful animals.

[0038] Next, the foot 300 (specifically, a hoof or the like) of the vermin that has come to the position of the binding trap 1 steps on the step portion 21 of the step piece 20, exerting a downward force, which exerts a downward force, for example, on the reduced diameter portion 212. At this time, as shown in Figures 5(B) and 6(B), the step piece 20 rotates with one end 11 of the tubular member 10 and the base end portion 211 as a fulcrum. As a result, the holding portion 22 of the step piece 20, to which the loop portion 31a of the wire rope 31 is hung, rotates so as to approach the horizontal direction.

[0039] Finally, the annular portion 31a of the wire rope 31 that has been fixing the foot piece 20 to the tubular member 10 is tightened, and the annular portion 31a is released from the outer periphery of the retaining portion 22 of the foot piece 20. As a result, as shown in Figures 5(C) and 6(C), the annular portion 31a is reduced in diameter, and the foot portion 300 of the vermin is tightened, making it possible to capture the vermin.

[0040] <Effects of this embodiment> As described above, the binding trap 1 of this embodiment is configured to include a tubular member 10, multiple footplate pieces 20, and a wire rope 31 having a ring portion 31a. This allows the footplate piece 20, which has a simple configuration, to be rotated around one end 11 of the tubular member 10 as a fulcrum, thereby tightening the ring portion 31a of the wire rope 31, and the trap can be operated reliably with a simple configuration. This prevents malfunctions that occur in conventional configurations even if problems such as freezing or foreign objects are caught.

[0041] Furthermore, by using a configuration using multiple step pieces 20, the trap can be set in motion by contracting the diameter of the annular portion 31a regardless of which step piece 20 the pest's foot 300 steps on, and the trap can be set in motion even with a small stepping force, ensuring that the pest is captured. Furthermore, by assembling the step pieces 20 from the outside to the tubular member 10, the step pieces 20 do not slide within the tubular member 10, and so the operation of the step pieces 20 is not impeded and operation can be stabilized.

[0042] In addition, the above-mentioned conventional general binding trap (see Patent Document 1) has a semicircular left and right wire holders with both ends pivoted to the side walls of the step and biased to stand up, a loop of a capture wire surrounding the semicircular outer periphery of the left and right wire holders when the left and right wire holders are in a lying down state, and a wire diameter reduction biasing mechanism that pulls the base of the loop of the wire surrounding the left and right wire holders to bias the loop to reduce its diameter. With this configuration, the conventional binding trap needs to be set at an angle larger than the maximum open state (180 degrees) so that the semicircular left and right wire holders do not jump up. Therefore, when a harmful animal steps on the step, a load (resistance) is generated to push the semicircular left and right wire holders to the 180 degree position. This load is different from the sensation felt from the ground when walking normally, and it becomes a trigger for the harmful animal to notice the presence of the trap. In contrast, the snare trap 1 does not use the semicircular arc-shaped left and right wire holders, and the loop portion 31a of the wire rope 31 is set in a maximum diameter state, so that the loop portion 31a can start to shrink before the harmful animal notices that it has stepped on the footboard 21. This allows the loop portion 31a of the wire rope 31 to reliably fasten the foot portion 300 of the harmful animal, and the harmful animal can be reliably captured.

[0043] <Modification of the step piece> FIG. 7 is a perspective view showing a modified example of the step piece. As shown in the figure, the step piece 20 may have a shape other than that of the above-mentioned embodiment. For example, the holding portion 22 of the step piece 20 may have a step, a recess, or a protrusion to prevent the wire rope 31 from slipping out. As an example, as shown in FIG. 7(A), the step piece 20A may have a step portion formed by providing a flat portion 222 and a protrusion 223 on the holding portion 22. This prevents the ring portion 31a of the wire rope 31 from coming off the holding portion 22 by restricting its movement at the protrusion 223. In addition, as shown in FIG. 7(B), the step piece 20B may have a recess with a groove 224 extending in the width direction. This prevents the ring portion 31a of the wire rope 31 from coming off the holding portion 22 by fitting it into the groove 224. By using these stopper configurations, the binding trap 1 can be easily assembled.

[0044] 7(C), a step plate piece 20C may be used in which the length L2 of the step plate portion 21 is variable. In this case, the length L2 of the step plate portion 21 can be changed by varying the position of the movable portion 21b corresponding to the tip end 213 side relative to the fixed portion 21a corresponding to the base end 211 side in the above-mentioned configuration using a fastening mechanism 21c. By using this, the step plate piece 20C can be used for tubular members 10 of different diameters.

[0045] <Modification of the cylindrical member and a binding trap using the same> Also, the binding trap 1A may be made by using a tubular member 10A having a different shape from the tubular member 10 in the above-mentioned embodiment. Fig. 8 is a perspective view showing a modified tubular member and a binding trap using the same. The tubular member 10A shown in Fig. 8(A) has a recess 11a of an arbitrary depth and a width W3 slightly wider than the width W1 of the base end 211 of the footplate piece 20 at one end 11. This allows the base end 211 of the footplate piece 20 to be positioned by inserting it into the recess 11a as shown in Fig. 8(B), and the binding trap 1A can be easily assembled.

[0046] <<Variations>> Also, the binding trap 1B may be as shown in FIG. 9. This figure is a perspective view showing another modified example of the binding trap. As shown in this figure, instead of the step piece 20 of the above-mentioned embodiment, a step 500 and a support piece 200 are used. The modified binding trap 1B differs from the above-mentioned embodiment in that it has a step 500 and a plurality of support pieces 200. The support piece 200 has a support part 201 that supports the step 500, and a holding part 202 that is connected to the outer periphery side of the cylindrical member 10A of the support part 201 so as to be bent outside the cylindrical member 10. In addition, the support part 201 is connected to the holding part 202 by a connection part 203.

[0047] That is, the binding trap 1B is mainly composed of a cylindrical member 10A, a step plate 500 having an outer diameter smaller than the hole (inner diameter) of the cylindrical member 10A, a support part 201 attached to the cylindrical member 10A and extending from the outside of the cylindrical member 10A toward the center of the cylindrical member 10A to support the step plate 500, and a plurality of support pieces 200 having a holding part 202 connected to the outside of the cylindrical member 10A so as to bend from the outer periphery side of the cylindrical member 10A of the support part 201, and a wire rope 31 having a ring part 31a that is hung on the outer periphery of the holding part 202 of the support piece 200 on the outer periphery of the cylindrical member 10A and fastens the support piece 200 to the outer periphery of the cylindrical member 10A. Even with this configuration, the support piece 200 can be rotated by applying a downward force to the step plate 500 by the foot part 300 of the harmful animal. According to this, the step plate 500 can be operated as a trap by dropping it into the cylindrical member 10A.

[0048] In addition, in the above-mentioned binding trap 1, the cylindrical member 10 and the step piece 20 are separate structures, but the cylindrical member 10 and the step piece 20 may be integrated. That is, the step piece 20 may be attached to one end 11 of the cylindrical member 10 so as to be rotatable in the above-mentioned direction. This makes it possible to prevent the step piece 20 from being lost.

[0049] The present technology can be configured as follows. (1) a tubular member; a step portion attached to the tubular member and extending from the outside of the tubular member toward the center of the tubular member to overlap a hole in the tubular member; and a plurality of step pieces each having a holding portion connected to the step portion so as to bend from the outer circumferential side of the tubular member on the outside of the tubular member; a wire rope having a loop portion that is wound around the outer periphery of the holding portion of the step piece on the outer periphery of the cylindrical member to fasten the step piece to the outer periphery of the cylindrical member; A trap equipped with.
