Description

Technical Field

[0001] The present invention relates to a tying wire including a wire body capable of forming an annular portion that encloses a capture target by slidably fixing one end portion between one end portion and the other end portion in the longitudinal direction, and a biasing member that reduces the diameter of the annular portion by relatively sliding one end portion of the wire body along the longitudinal direction, and a tying trap configured to include such a tying wire and a treadle.

Background Art

[0002] In order to reduce the adverse effects on agriculture and forestry and prevent the collapse of the ecosystem balance, deer are systematically captured for the purpose of adjusting the deer population. In this case, when capturing deer, a tying trap that can be introduced at low cost, is easy to install, and can capture a capture target more safely than using a hunting rifle or the like is widely used.

[0003] For example, Patent Document 1 below discloses an invention of a tying trap including a treadle and a tying ring mounting belt. In this case, the treadle includes an installation frame buried in the ground, a substantially U-shaped strip plate capable of positioning the tying ring mounting belt around the installation frame in an expanded diameter state, and a treadle body provided on the installation frame. Further, the tying ring mounting belt is composed of a tying wire (hereinafter, also referred to as a "wire body") and a "pushing spring type tightening device" including a coil spring member through which the wire body is passed.

[0004] When capturing deer or the like using this snare trap, the annular portion of the wire body in the snare ring mounting belt is set so as to be spanned across both strip plates of the tread plate buried in the ground, and in this state, the coil spring member is compressed and extended. As a result, with the reduction in the diameter of the annular portion of the wire body being blocked by both strip plates, a force to reduce the diameter of the annular portion (a biasing force in the extending direction of the coil spring member) is applied by the force with which the coil spring member attempts to extend. In such a state, when the tread plate body is punched through by a deer, the restriction on the reduction of the diameter of the annular portion by the strip plates is released, and the leg is snared by the annular portion (wire body) reduced in diameter by the biasing force of the coil spring member, and the deer is captured.

[0005] On the other hand, Patent Document 2 below discloses an invention of a capture remote release system for a snare trap (a snare trap that can be remotely released; hereinafter, simply referred to as a "snare trap"). This snare trap includes a tread plate, a capture wire (hereinafter, also referred to as a "wire body"), a spring mechanism for reducing the diameter of the annular portion of the wire body, and a contraction prevention device for holding the spring mechanism with respect to the wire body so that the force in the diameter reduction direction of the annular portion by the spring mechanism does not relax.

[0006] In this case, in this snare trap, the above-described contraction prevention device includes a pair of opening and closing arms that sandwich the wire in an openable and closable manner with a pivot axis parallel to the wire body as the rotation center, a lock pin for closing and fixing both opening and closing arms in a state where the wire body is sandwiched, and an actuator for advancing and retreating the lock pin. Further, in this contraction prevention device, the actuator is operated by remote control of a wireless remote controller carried by the user to release the fixing of both opening and closing arms by the lock pin, so that the sandwiching of the wire body by both opening and closing arms is released and the force in the diameter reduction direction of the annular portion by the spring mechanism is relaxed.

[0007] When capturing deer or the like using this noose trap, similar to the noose trap disclosed in Patent Document 1 above, when the pedal is stepped through by a deer, the spring mechanism causes the diameter of the ring portion of the wire body to decrease, the legs are noosed, and the deer is captured. At this time, a detection output signal for notifying that some kind of animal has been captured is transmitted from the contraction prevention device. The user who recognizes that an animal has been captured upon receiving this signal visits the location where the noose trap is installed to obtain the captured animal (such as a deer). At this time, by operating the wireless remote control to release the clamping of the wire body by the opening and closing arm, the force in the diameter-reducing direction of the ring portion by the spring mechanism is relaxed, and it becomes possible to easily remove the noose trap from the legs of the captured animal.

Summary of the Invention

Problems to be Solved by the Invention

[0009] However, the noose trap disclosed in the above patent documents has the following problems to be solved.

[0010] Specifically, in the noose traps disclosed in Patent Documents 1 and 2 above, a configuration is adopted in which the legs that have stepped through the pedal are noosed by reducing the diameter of the ring portion in the wire body to capture the target to be captured. In this case, in capture using a noose trap, unlike capture using a hunting rifle, it is not known what kind of animal will be captured by the noose trap. Even if it is installed for the purpose of capturing deer, mis-capture may occur where an unintended animal other than a deer is captured.

[0011] Here, when the noose trap disclosed in Patent Document 1 is set up for the purpose of capturing deer, if a bear is accidentally captured by this noose trap, when the bear whose limbs are tied by the wire body tries to escape from the installation location, the diameter of the ring part is reduced, and as a result, the wire body may bite into the bear's limbs and cause injury. Also, for a bear that is not the target of capture, it is necessary to release it. However, in order to ensure the safety of the operator, it is necessary to put the captured bear to sleep using anesthetic gun or the like, and before the bear wakes up, release the noose trap and move it to the release location. For this reason, the work of releasing the bear when it is accidentally captured is very complicated.

[0012] Furthermore, when the bear with its limbs tied struggles, entanglement occurs in the wire body. In this state, when the bear tries to escape from the spot, by repeatedly pulling back the wire body, wire breakage or kinking may occur in the wire body, or the wire body that ties the limbs may be bitten by the bear trying to remove it, resulting in wire breakage or kinking. For this reason, when the state of the bear being accidentally captured continues for a long time, the strength of the wire body decreases. For example, there is a high possibility that the wire body will be cut during the operation of releasing the accidentally captured bear, and the operator will be attacked by the bear. Also, even if the wire body is not cut as described above, when wire breakage or kinking occurs and the strength of the wire body is greatly reduced, it becomes difficult to reuse the noose trap. For this reason, it becomes necessary to introduce a new noose trap, and the cost required for capturing the target deer increases.

[0013] On the other hand, in the snare disclosed in Patent Document 2, when a bear is accidentally captured, the operation of the wireless remote control (remote operation) is performed at a sufficient distance from the installation location of the snare (the location where the bear was accidentally captured), so that the clamping of the wire body by the opening and closing arm can be released (the relaxation of the force in the diameter-reducing direction of the ring portion by the spring mechanism). As a result, without approaching the accidentally captured bear, the ring portion can be made easily removable from the bear's limbs. Therefore, with this snare, it is possible to release the animal relatively safely because the bear can remove the wire body from its limbs by itself and leave the installation location of the snare without having to perform the operation of putting the accidentally captured bear to sleep using an anesthetic gun or the like and removing the wire body (ring portion) from the bear's limbs.

[0014] However, when a bear is accidentally captured by the snare disclosed in Patent Document 2, until the user visits the site and confirms the captured animal, it is impossible to identify whether the target deer has been captured or a bear that requires releasing has been captured. Therefore, when a bear is accidentally captured, until it is recognized that some animal has been captured by receiving the detection output signal, and after visiting the installation location of the snare and recognizing that it is an accidental capture and then operating the wireless remote control, the state where the bear's limbs are snared by the snare (ring portion) continues. As a result, there is a risk that the bear may be injured by thrashing around with the wire body biting into its limbs before the clamping of the wire body by the opening and closing arm is released after being accidentally captured. Also, as described above, there is a risk that the wire body may break or kink due to the thrashing of the bear with its limbs snared.

[0015] Even if the time until the clamping of the wire body by the opening and closing arm is released from the miscapture of the bear can be sufficiently shortened, just releasing the clamping of the wire body by the opening and closing arm does not prevent the bear with its limbs tied from pulling the wire body as it tries to leave the installation location. When this happens, the pulling force causes the ring portion to further reduce in diameter and bite into the limbs, making it difficult for the ring portion (wire body) to come off the bear's limbs. For this reason, it may take a long time until the capture state is released, and it is difficult to suitably avoid injury to the bear and a decrease in the strength of the wire body.

[0016] Furthermore, in the noose trap disclosed in Patent Document 2, since its structure is complex, it is difficult to reduce the manufacturing cost, and there is a risk of equipment failure and malfunction. Also, since it requires power to receive an operation signal from a wireless remote control, operate an actuator, or transmit a detection signal for capture notification, it requires regular battery replacement, and the work of managing the equipment is also extremely complicated.

[0017] The present invention has been made in view of these problems to be solved, and its main object is to provide a noose trap that can avoid injury to a bear or the like that has been miscaptured, safely and easily release the captured bear or the like, reduce the manufacturing cost, and reduce the burden required for equipment management.

Means for Solving the Problems

[0018] To achieve the above object, the noose wire according to claim 1 is a noose wire for a noose trap, comprising a wire body capable of forming a ring portion for noosing a capture target by fixing one end portion between one end portion and the other end portion in the longitudinal direction so as to be relatively slidable along the longitudinal direction, and a biasing member for reducing the diameter of the ring portion by relatively sliding the one end portion along the longitudinal direction.

[0021] Claim 4 The binding trap according to... includes the binding wire according to any one of claims 1 to 3 ... and a tread plate capable of maintaining the annular portion of the binding wire in an expanded diameter state.

Advantages of the Invention

[0022] In the binding wire according to claim 1, a fixture for fixing one end between one end and the other end of a wire body capable of forming an annular portion for enclosing a capture target is is configured by a snap shackle, and a string-like body is attached to the release pin of the snap shackle. provided with a fixing release mechanism for releasing the fixing of one end between one end and the other end of the wire body when the string-like body is pulled. Further, in the binding trap according to claim 4 ... includes the above binding wire and a tread plate capable of maintaining the annular portion of the binding wire in an expanded diameter state.

[0023] Therefore, according to the binding wire according to claim 1 and the binding trap according to claim 4 ..., when a bear having a habit of gnawing and pulling when its leg is enclosed is erroneously captured, the fixing of one end of the wire body to the fixture or the fixing between the one end portion and the other end portion of the wire body with respect to the fixture Since the capture state is released when it is released, the bear can be easily released in a short time without causing serious injury to the bear's limbs and without performing a dangerous animal release operation. In addition, since its structure is very simple, it can be manufactured at low cost, and since no power source or the like is required, the burden required for its management can be sufficiently reduced. Also, by using an existing snap shackle, a binding wire and a binding trap can be manufactured at low cost.

Embodiments for Carrying Out the Invention

[0028] Hereinafter, embodiments of the "tying wire" and the "tying trap" will be described with reference to the accompanying drawings.

[0029] The tying trap 100 shown in Fig. 1 is an example of a "tying trap", and includes a tying wire 1 and a "pedal" (not shown), and is configured to be able to capture a deer or the like as a "target to be captured". In this case, as an example of the "pedal" used in the tying trap 100 of this example, an existing pedal such as the pedal used in the tying traps disclosed in the above-mentioned Patent Documents 1 and 2 can be used. Since the configuration of this "pedal" is well-known, illustration and detailed description are omitted.

[0030] The tying wire 1 is an example of a "tying wire", and includes a wire body 2, a coil spring 3, a stopper 4, a snap shackle 5, and a fixing release wire 6. The wire body 2 corresponds to the "wire body" and is configured of, for example, a stranded wire of stainless steel. This wire body 2 is configured such that an end portion P1 can be fixed to be relatively slidable along the longitudinal direction at an intermediate portion P3 (an example of "between one end portion and the other end portion") between the end portions P1 and P2 in the longitudinal direction, so as to form an annular portion Pc for tying the "target to be captured".

[0031] The coil spring 3 corresponds to the "biasing member", and is disposed between the end portion P2 and the intermediate portion P3 of the wire body 2 with sliders 3a and 3b disposed at both end portions thereof, so that the end portion P1 of the wire body 2 can be relatively slid along the longitudinal direction with respect to the intermediate portion P3 to generate a biasing force for reducing the diameter of the annular portion Pc. The stopper 4 functions as a "fastener" for maintaining the contracted and elongated state of the coil spring 3 by restricting the movement of one end portion (the end portion on the end portion P2 side: the end portion where the slider 3b is attached) of the coil spring 3 that has been contracted and elongated so as to obtain sufficient biasing force when the binding wire 1 is set on the "pedal" with respect to the wire body 2. This stopper 4 adopts a configuration in which sliding with respect to the wire body 2 is restricted / permitted by tightening / loosening the wing nut 4a.

[0032] The snap shackle 5 is an example of a "fastener" composed of a "snap shackle". As shown in FIGS. 2 to 5, it includes a shackle body 11, a release pin 12, a coil spring 13, and a washer 14, and is configured to be able to fix the end portion P1 to the intermediate portion P3 of the wire body 2. The shackle body 11 includes a base member 11a, an arm-shaped member 11b, and a rotation shaft 11c, and the arm-shaped member 11b is pivotally supported by the base member 11a so as to be rotatable about the rotation shaft 11c. Further, the shackle body 11 includes two annular portions, an annular portion C1 provided on the base member 11a and an annular portion C2 formed by the base member 11a and the arm-shaped member 11b.

[0033] In this case, in the snap buckle 5 of this example, as shown in FIGS. 4 and 5, an insertion hole 11h is provided at one end of the arm-shaped member 11b (the end opposite to the side supported by the rotation shaft 11c). Thus, in this snap buckle 5, as shown in FIG. 4, when the tip of the release pin 12 through which the base member 11a is inserted is inserted into the insertion hole 11h of the arm-shaped member 11b, the rotation of the arm-shaped member 11b with respect to the base member 11a is restricted and the ring portion C2 is maintained in the closed state. Also, as shown in FIG. 5, when the tip of the release pin 12 is disengaged from the insertion hole 11h, the rotation of the arm-shaped member 11b with respect to the base member 11a is allowed and the ring portion C2 can be shifted from the closed state to the open state.

[0034] In addition, in the tying wire 1 of this example, as shown in FIGS. 2 and 3, as an example, when the intermediate portion P3 of the wire body 2 is inserted into the ring portion C1 of the shackle body 11, the end portion P1 of the wire body 2 is fixed to the ring portion C2 of the shackle body 11. Thus, when the ring portion C2 is shifted to the open state, the end portion P1 of the wire body 2 is configured to be disengaged from the snap buckle 5. Instead of such a configuration, when the end portion P1 of the wire body 2 is fixed to the ring portion C1 of the shackle body 11 and the intermediate portion P3 of the wire body 2 is inserted through the ring portion C2 of the shackle body 11, it can also be configured such that when the ring portion C2 is shifted to the open state, the intermediate portion P3 of the wire body 2 is disengaged from the snap buckle 5 (not shown).

[0035] The release pin 12 corresponds to the "release pin". As shown in FIGS. 4 and 5, in a state where it is inserted into the base member 11a, it is biased in the direction of arrow A1 with respect to the base member 11a by the coil spring 13. In this case, an insertion hole 12h for attaching the fixing release wire 6 is provided at the end of the release pin 12 on the side opposite to the end that is inserted into the insertion hole 11h of the arm-shaped member 11b as described above. Therefore, in the tying wire 1 of this example, in the normal state, one end of the release pin 12 is inserted into the insertion hole 11h of the arm-shaped member 11b by the biasing force of the coil spring 13, and the rotation of the arm-shaped member 11b with respect to the base member 11a is restricted. When the fixing release wire 6 is pulled and the release pin 12 is slid in the direction of arrow A2 against the biasing force of the coil spring 13, one end of the release pin 12 is disengaged from the insertion hole 11h, and a configuration is adopted in which the rotation of the arm-shaped member 11b with respect to the base member 11a is allowed (an example of a "fixing release mechanism").

[0036] The washer 14 corresponds to the "flange portion". It is disposed at the attachment site of the fixing release wire 6 on the release pin 12 (near the insertion hole 12h) such that its outer edge portion protrudes from the base member 11a (see FIG. 2). Although an example in which the "flange portion" is constituted by the washer 14 through which the release pin 12 is inserted will be described, instead of such a configuration, the "flange portion" can be integrally provided on the "release pin" (the shaft portion and the flange portion of the release pin are integrally formed) (not shown).

[0037] The fixing release wire 6 is an example of a "string-like body", and as described above, one end thereof is fixed to the release pin 12 of the snap shackle 5. In this case, in the binding wire 1 of this example, the fixing release wire 6 is constituted by covering a tubular body 6a made of an elastic resin pipe having an outer diameter larger than that of the wire body 2 with a stranded wire of stainless steel having a smaller diameter than the wire body 2. Thus, in the binding wire 1 of this example, the fixing release wire 6 (tubular body 6a) has a larger outer diameter than the wire body 2. Further, in the binding wire 1 of this example, as shown in FIGS. 2 and 3, the fixing release wire 6 inserted through the insertion hole 12h of the release pin 12 is fixed to the shackle body 11 by the binding bands 15a and 15b, and is also fixed to the coil spring 3 (slider 3a disposed at one end of the coil spring 3) by the binding band 15c.

[0038] Next, the usage method of the binding trap 100 will be described. Note that the assembly of the binding wire 1 (the operation of integrating the wire body 2, the coil spring 3, the stopper 4, the snap shackle 5, and the fixing release wire 6 as shown in FIG. 1) is already completed, and the description thereof will be omitted.

[0039] For example, when capturing a deer as a "capture target" using the binding trap 100, a "footrest" is buried at a location suitable for capture. Next, the end portion P2 of the binding wire 1 is fixed to an anchor stuck into the ground, a tree growing in the vicinity, or the like. Subsequently, the end portion P1 of the wire body 2 is fixed to the ring portion C2 of the snap shackle 5.

[0040] At this time, the release pin 12 of the snap shackle 5 is slid with respect to the base member 11a in the direction of arrow A1 shown in FIG. 4 against the biasing force of the coil spring 13, so that the tip of the release pin 12 is disengaged from the insertion hole 11h of the arm-shaped member 11b. In this state, as shown in FIG. 5, the arm-shaped member 11b is rotated with respect to the base member 11a. Next, after hooking the small ring-shaped portion provided at the end P2 of the wire body 2 on the arm-shaped member 11b, the arm-shaped member 11b is rotated with respect to the base member 11a so that the tip of the arm-shaped member 11b (the end opposite to the end pivotally supported by the pivot shaft 11c) abuts against the base member 11a. Subsequently, by weakening the force for sliding the release pin 12, the release pin 12 is slid with respect to the base member 11a in the direction of arrow A1 by the biasing force of the coil spring 13. As a result, the tip of the release pin 12 is inserted into the insertion hole 11h of the arm-shaped member 11b, and the detachment of the wire body 2 (end P1) from the ring portion C2 is restricted.

[0041] Next, after arranging the wire body 2 around the "pedal" so that the "pedal" is located inside the ring portion Pc of the wire body 2, the stopper 4 is slid toward the intermediate portion P3 (snap shackle 5) with the wing nut 4a of the stopper 4 loosened. At this time, as the stopper 4 slides, the slider 3b is slid, so that the coil spring 3 is compressed and elongated, and a biasing force is generated in a direction to separate the slider 3a from the slider 3b (the stopper 4 in contact with the slider 3b). As a result, the diameter of the ring portion Pc is reduced, and the "pedal" is constricted by the wire body 2.

[0042] Subsequently, by further sliding the stopper 4, the coil spring 3 is sufficiently compressed and elongated so that the ring portion Pc is further reduced in diameter by the biasing force of the coil spring 3 when the "pedal" is punched out. In this state, the wing nut 4a is tightened to restrict the sliding of the stopper 4 with respect to the wire body 2. After that, by covering the installed snare 100 with fallen leaves or the like so that the snare 100 is hidden, the installation of the snare 100 is completed.

[0043] In the noose 100 installed as described above, when the "footrest" is punched through by a deer, the restriction on the diameter reduction of the annular portion Pc is released, and the leg is noosed by the annular portion Pc (wire body 2) that has been reduced in diameter by the biasing force of the coil spring 3, and the deer is captured. At this time, the captured deer tries to move from the installation location of the noose 100 and pulls the noose wire 1 that is noosing its leg. However, to the extent that such a force is applied, the end portion P1 of the wire body 2 does not detach from the snap shackle 5 (ring portion C2), so the state in which the deer is captured is maintained.

[0044] In this case, when the deer with its leg noosed thrashes around, the release pin 12 is unintentionally slid with respect to the base member 11a by the force generated when the fixing release wire 6 is swung around with the leg, allowing the arm-shaped member 11b to rotate, and there is a risk that the end portion P1 of the wire body 2 will detach from the snap shackle 5 (ring portion C2). However, in the noose 100 (noose wire 1) of this example, as described above, the fixing release wire 6 is fixed to the snap shackle 5 and the coil spring 3 (slider 3a) by the binding bands 15a to 15c. Therefore, with a force of the degree generated when the deer thrashes around, the unintentional sliding of the release pin 12 does not occur, and the state in which the end portion P1 of the wire body 2 is fixed to the snap shackle 5 (ring portion C2) is preferably maintained.

[0045] On the other hand, in this noose 100, when a bear that is not a "capture target" is mis-captured, the end portion P1 of the wire body 2 fixed to the intermediate portion P3 by the snap shackle 5 detaches from the snap shackle 5 (ring portion C2), and the capture of the bear is released.

[0046] Specifically, for example, when the "pedal" is punched through by the front paw (hand) of a bear, the front paw is constricted by the annular portion Pc (wire body 2) whose diameter is reduced by the biasing force of the coil spring 3 as described above, and the bear is erroneously captured. In this case, when the erroneously captured bear attempts to move away from the installation location of the constriction trap 100, although the wire body 2 constricting the front paw is pulled, the end P1 of the wire body 2 does not detach from the snap shackle 5 (ring portion C2) to the extent that such a force is applied. However, the inventor found that when the bear is in a state where it cannot move from the location because its front paw is constricted, it has the habit of gnawing and pulling on the string-like body (in this example, the constriction wire 1) that constricts the front paw in order to remove it.

[0047] In the constriction wire 1 (constriction trap 100) of this example invented by the inventor who discovered such a habit, when the erroneously captured bear attempts to gnaw and pull on the wire body 2, the fixing release wire 6 is pulled, and as a result, the release pin 12 is slid relative to the base member 11a against the biasing force of the coil spring 13. Thus, the tip of the release pin 12 detaches from the insertion hole 11h of the arm-like member 11b, and rotation of the arm-like member 11b relative to the base member 11a is permitted. Therefore, due to the force pulling on the fixing release wire 6, the end P1 of the wire body 2 detaches from the arm-like member 11b, and as a result, the wire body 2 comes off the front paw, and the erroneous capture of the bear is promptly released.

[0048] Also, when the "pedal" is punched through by the hind paw of a bear, the hind paw is constricted by the annular portion Pc (wire body 2) whose diameter is reduced by the biasing force of the coil spring 3 as described above, and the bear is erroneously captured. In this case, when the erroneously captured bear attempts to move away from the installation location of the constriction trap 100, the wire body 2 constricting the hind paw is pulled. At this time, as described above, to the extent of the force applied when the bear attempts to move from the installation location, the end P1 of the wire body 2 does not detach from the snap shackle 5 (ring portion C2), but when the hind paw is constricted State When the bear trying to escape from the restraint pulls the wire body 2 with an even stronger force, the edge of the washer 14 disposed on the release pin 12 catches on the hind leg of the bear. State When the wire body 2 is pulled, the release pin 12 is slid relative to the base member 11a. At this time, the tip of the release pin 12 disengages from the insertion hole 11h of the arm-shaped member 11b, allowing the arm-shaped member 11b to rotate relative to the base member 11a. As a result, the end P1 of the wire body 2 is disengaged from the arm-shaped member 11b, the wire body 2 comes off the hind leg, and the mis-capture of the bear is released.

[0049] In addition, as described above, when the front leg (hand) is restrained State even when the fixing release wire 6 is not pulled, when the bear trying to escape from the restraint pulls the wire body 2 with an even stronger force, the washer 14 disposed on the release pin 12 catches on the front leg of the bear. State When the bear trying to escape from the restraint pulls the wire body 2 with an even stronger force, the washer 14 disposed on the release pin 12 catches on the front leg of the bear. State When the wire body 2 is pulled, the release pin 12 is slid relative to the base member 11a. As a result, the end P1 of the wire body 2 is disengaged from the arm-shaped member 11b, the wire body 2 comes off the front leg, and the mis-capture of the bear is released.

[0050] In this case, as described above, in the restraint wire 1 (restraint trap 100) of this example, since the end P1 of the wire body 2 is fixed to the snap shackle 5 and the slider 3a by the binding bands 15a to 15c, when the bear with its front or hind legs restrained struggles, the release pin 12 will not be slid relative to the base member 11a. However, when the fixing release wire 6 is gnawed and pulled, or when the force exerted by the bear with its legs restrained State When a large force is applied when trying to remove it, the binding bands 15a to 15c are torn and the slide of the release pin 12 is allowed. As a result, when a deer or the like that is weaker than a bear is captured, the capture is not unintentionally released, and for a bear that is not the target of capture, even if the user does not perform the operation of releasing the capture (releasing the animal), the bear bites the wire body 2 and tries to pull it. The capture is released by the force (the force by which the fixing release wire 6 is pulled).

[0051] Also, in the binding wire 1 (binding trap 100) of this example, even if the user does not recognize that a bear has been erroneously captured, the capture is released as described above by the action of the captured bear itself. For this reason, the state of erroneous capture does not continue for a long time, and the capture is released before wire breakage or kinking occurs in the wire body 2. As a result, not only is the operation of releasing the erroneously captured bear unnecessary, but for the binding wire 1 (binding trap 100) released by the bear, it can be reused simply by fixing the end P1 of the wire body 2 to the snap shackle 5 (ring portion C2) again. Therefore, an increase in the cost required for capturing deer can be avoided.

[0052] As described above, in this binding wire 1, a "fixing tool (in this example, a snap shackle 5)" that fixes the end P1 between the ends P1 and P2 in the wire body 2 capable of forming a ring portion Pc for binding a capture target such as a deer is attached to the "fixing tool" separately from the wire body 2. It is provided with a "fixing release mechanism" in which the fixing of the end P1 to the intermediate portion P3 in the wire body 2 is released when the fixing release wire 6 is pulled. Further, this binding trap 100 includes the above-described binding wire 1 and a "pedal" capable of maintaining the ring portion Pc of the binding wire 1 in an expanded diameter state.

[0053] Therefore, according to this binding wire 1 and binding trap 100, when a bear having the habit of biting and pulling when its leg is in a bound state is erroneously captured, the fixing of the end P1 of the wire body 2 to the "fixing tool" (or the fixing between the intermediate portion P3 of the wire body 2 with respect to the "fixture") Since the locking is released and the capture state is released, it is possible to easily release the bear in a short time without causing serious injury to the bear's limbs and without performing dangerous animal release operations. In addition, since its structure is very simple, it can be manufactured at low cost, and since no power source is required, the burden required for its management can be sufficiently reduced.

[0054] Also, in this tying wire 1, the fixing release wire 6 is formed to have a larger diameter than the wire body 2. Therefore, according to this tying wire 1 and the tying trap 100, since a bear with its leg tied can easily bite and pull the fixing release wire 6, it is possible to more easily release a bear that has been erroneously captured.

[0055] Furthermore, in this tying wire 1, the "fastener" is constituted by a "snap shackle", and the fixing release wire 6 is attached to the release pin 12 of the snap shackle 5. Therefore, according to this tying wire 1 and the tying trap 100, it is possible to manufacture the tying wire 1 and the tying trap 100 at low cost by using an existing snap shackle 5.

[0056] Also, in this tying wire 1, the snap shackle 5 as the "fastener" has an outer edge portion at the attachment portion of the fixing release wire 6 on the release pin 12 11 so that a "flange portion (in this example, a washer 14 attached to the release pin 12))" is disposed so as to protrude from the shackle body. Therefore, according to this tying wire 1 and the tying trap 100, even when a bear that has been erroneously captured does not perform an operation of biting and pulling the fixing release wire 6, the release pin 12 can be slid along with the operation of the bear pulling the wire body 2, and the capture state can be surely released.

[0057] Note that the configurations of the "tying wire" and the "tying trap" are not limited to the examples of the configurations of the above-mentioned tying wire 1 and tying trap 100.

[0058] For example, by fixing the end portion P1 of the wire body 2 to the annular portion of the shackle body 11 at C2 (hooking a small annular portion provided at the end portion P1 on the arm-shaped member 11b of the snap shackle 5), when the annular portion C2 is shifted to the open state, the end portion P1 of the wire body 2 can be disengaged from the snap shackle 5. This is taken as an example of the configuration. Mentioned However, the fixing of the end portion P1 to the snap shackle 5 (annular portion C2) is not limited to the configuration as in this example.

[0059] Specifically, the tying wire 1A (tying trap 100A) shown in FIGS. 6 and 7 is another example of a "tying wire (tying trap)". Different from the fixing structure of the snap shackle 5 (annular portion C2) at the end portion P1 of the above-mentioned tying wire 1 (tying trap 100), a configuration is adopted in which a "stopper" (in this example, a washer 2a) is provided at the end of the end portion P1 to restrict the end portion P2 from disengaging from the closed annular portion C2. In this case, in this wire 1A (tying trap 100A), as the "stopper", a washer 2a composed of a flat round washer whose outer diameter is sufficiently larger than the inner diameter of the annular portion C2 is adopted. For the components having the same functions as those of the above-mentioned tying wire 1 (tying trap 100) in this tying wire 1A (tying trap 100A), the same reference numerals are given and the overlapping explanations are omitted.

[0060] In this tying wire 1A (tying trap 100A), in the same manner as the above-mentioned tying wire 1 (tying trap 100), when a wrongly caught bear tries to bite and pull the wire body 2, the fixing wire 6 is pulled and the release pin 12 is slid relative to the base member 11a against the biasing force of the coil spring 13. As a result, the tip of the release pin 12 is disengaged from the insertion hole 11h of the arm-shaped member 11b, and the rotation of the arm-shaped member 11b with respect to the base member 11a is allowed. At this time, with the rotation of the arm-shaped member 11b with respect to the base member 11a, the portion of the annular portion C2 where the washer 2a is in contact expands. As a result, the end portion P1 fixed to the annular portion C2 via the washer 2a is smoothly disengaged from the annular portion C2, and the fixing of the end portion P1 to the snap shackle 5 (annular portion C2) is released.

[0061] Here, by adopting a flat round washer as a "stopper" like the tying wire 1A (tying trap 100A) in this example, it is possible to sufficiently reduce the manufacturing cost by using an existing flat round washer without manufacturing a dedicated "stopper". Further, by adopting a "plate-like body whose width gradually expands along the length direction of the fixed wire body 2" like the washer 2a, when a force in a direction to separate the end portion P1 from the annular portion C2 is applied in a state where the rotation of the arm-like member 11b with respect to the base member 11a is allowed, a force acts on the base member 11a and the arm-like member 11b to move away from each other the portions where the "stopper" is in contact, whereby the arm-like member 11b can be smoothly rotated with respect to the base member 11a, and thus the end portion P1 of the wire body 2 can be surely separated from the snap shackle 5 (annular portion C2). Therefore, for the fixing of the wire body 2 (end portion P1) to the snap shackle 5 (annular portion C2), it is preferable to adopt a configuration like the tying wire 1A (tying trap 100A).

[0062] Also, although the tying wire 1 of the "push spring type tightening device" configured by the coil spring 3 as an "urging member" has been described as an example, the "urging member" is not limited to a "push spring", and a "twist spring (pine needle type spring) or a "pull spring" can also be adopted to configure the "tying wire" (not shown). Further, although an example has been described in which the tubular body 6a is covered with a stranded wire having a smaller diameter than the wire body 2 to form a fixing release wire 6 having a larger diameter than the wire body 2, the "string-like body" can also be configured by a stranded wire having a larger diameter than the "wire body". Furthermore, although an example has been described in which the "snap shackle (snap shackle 5)" configures a "fastening tool", instead of the "snap shackle", a "fastening tool" can also be configured by providing various "fixing release mechanisms" in which the fixing of one end portion with respect to the other end portion between one end portion and the other end portion of the "wire body" is released by pulling a "string-like body" separate from the "wire body" (not shown).

Industrial Applicability

[0063] According to the present invention, when a bear having a habit of biting and pulling when its legs are enclosed is erroneously captured, the fixing release wire 6 is pulled, and the fixing of the end portion P1 of the wire body 2 to the snap shackle 5 is released, and the captured state is released. Therefore, the bear can be easily released in a short time without causing serious injury to the bear's hands and feet and without performing a dangerous animal release operation, so it can be widely applied to an enclosing wire and an enclosing trap for the purpose of capturing deer and the like.
