Summary of the Invention

Problems to be Solved by the Invention

[0004] However, conventional snare traps have room for improvement in terms of the degree of freedom in their installation. For example, in the snare trap described in Patent Document 1, the base end elastic device receiving portion and the tip end elastic device receiving portion are provided with a base end pipe member and a tip end pipe member that extend toward each other from the base end elastic device receiving portion and the tip end elastic device receiving portion, with the charged coil-shaped elastic device fitted into them. By covering the charged coil-shaped elastic device with both pipe members, it is made less susceptible to the influence of the external environment. However, since the two pipe members that cover the charged coil-shaped elastic device extend in a straight line from the base material, this may reduce the degree of freedom in installing the snare trap. [Means for solving the problem]

[0005] This invention was created in view of the above circumstances and with the aim of solving these problems, and the invention of claim 1 comprises a base material installed at an animal capture site, a foot plate provided on the base material so as to be able to move up and down and which moves downward when stepped on by the animal's legs, a pair of operating members having a curved shape with a straddle portion and two leg portions and an opening formed on the tip side, with the tip edges of the two leg portions being pivotally supported on the foot plate via a support shaft so as to be able to swing up and down with the openings facing each other, a wire whose base end is attached to a fixed member near the capture site and which extends from the base end and has a slinging ring portion formed at the tip of the wire extension portion for performing a slinging operation, a coil-shaped elastic device through which the slinging ring portion side of the wire extension portion passes and which stores energy to perform a slinging operation of the slinging ring portion, and the base end and tip of the coil-shaped elastic device respectively receive and support the In a snare trap comprising a base-side elastic device receiving portion and a tip-side elastic device receiving portion, the snare ring portion, which is expanded against the accumulated force of the coil-shaped elastic device, is released from the operating member, which swings in response to the downward movement of the supporting shaft linked to the animal's leg stepping on the footplate, in a standby state in which the straddle portion is wound around the operating member, which is set lower than the support shaft, thereby snare the leg of the animal that has stepped on the footplate, wherein the base-side elastic device receiving portion and the tip-side elastic device receiving portion are provided with a base-side pipe member and a tip-side pipe member extending from the base-side elastic device receiving portion and the tip-side elastic device receiving portion, respectively, with a gap between their opposing edges, and the accumulated force of the coil-shaped elastic device is configured such that the exposed portion exposed from the gap between the edges is bendable together with the wire extension portion. Furthermore, the invention of claim 2 is a snare trap according to claim 1, wherein the base material has a rectangular tubular shape having a pair of opposing one-sided portions and a pair of opposing other-sided portions, the tip-side elastic receiving portion of the wire extension portion has an extension base end extending from the snare ring portion that extends outside the base material in a bendable state from a recessed groove portion provided in the widthwise central portion of one of the one-sided portions, the tip-side pipe member is set to a length that reaches the corner portion of the base material on the bent side when the wire portion extending from the recessed groove portion of the wire extension portion is bent along one of the one-sided portions, and the base-side pipe member is configured to allow arrangement in the bending direction, including arrangement along one of the opposing sides, by bending the energized coil-shaped elastic at the corner portion. Furthermore, the invention of claim 3 is a snare trap according to claim 2, characterized in that the length of the tip pipe member up to the corner portion is not long enough to reach one corner portion of the base material, and the base pipe member is configured such that the coil-shaped elastic device curves at the corner portion from one side to the other side, so that it is arranged along the other side. Furthermore, the invention of claim 4 is a snare trap according to claim 1, characterized in that the gap between the edges where the charged coil-shaped spring is exposed is 5 to 10 cm. Furthermore, the invention of claim 5 is a snare trap according to claim 1, characterized in that the length of the grippable portion of the base end pipe member, including the base end elastic receiver portion, is set to 8.5 to 15 cm, which is greater than the average hand width of an adult male, which is 8.3 cm. Furthermore, the invention of claim 6 is a snare trap according to claim 1, characterized in that the length of the base end pipe member, including the base end elastic receiving portion, is longer than the length of the tip end pipe member, including the tip end elastic receiving portion. Furthermore, the invention of claim 7 is a snare trap according to claim 1, wherein the end of the tip-side elastic receiving portion on the snare ring side is formed in a spherical shape and has a wire through-hole in its center through which the wire extension portion passes, and the wire through-hole is an elongated hole extending along the spherical surface. [Effects of the Invention]

[0006] According to the invention of claim 1, the base end elastic device receiving portion and the tip end elastic device receiving portion are provided with a gap between their opposing edges, with the base end pipe member and the tip end pipe member extending from the base end elastic device receiving portion and the tip end elastic device receiving portion into which the charged coil-shaped elastic device is fitted. The charged coil-shaped elastic device is configured so that the exposed portion exposed through the gap between the edges can be bent together with the wire extension portion. This makes the charged coil-shaped elastic device less susceptible to external environmental influences by covering it with both pipe members, while also allowing the charged coil-shaped elastic device (including the wire extension portion and both pipe members) to be bent, thereby increasing the degree of freedom in setting up the snare trap. Furthermore, according to the invention of claim 2, the tip-side pipe member and the base-side pipe member can be arranged in a bent shape along the periphery of the base material, further increasing the degree of freedom in setting up the snare trap. Furthermore, according to the invention of claim 3, when arranging the tip-side pipe member and the base-side pipe member in a bent shape along the periphery of the base material, it becomes possible to position the tip-side pipe member and the base-side pipe member closer to the base material. Furthermore, according to the invention of claim 4, the gap between the exposed edges of the charged coil-shaped projectile is set to 5 to 10 cm, making it possible to bend the charged coil-shaped projectile vertically or in a folded shape. Furthermore, according to the invention of claim 5, the length of the grippable portion of the base end pipe member, including the base end elastic device receiving portion, is set to 8.5 to 15 cm, which exceeds the average hand width of an adult male, 8.3 cm. Therefore, when gripping the base end pipe member to store energy in the coil-shaped elastic device, a sufficient grip width can be secured, improving the workability of the operation. Furthermore, according to the invention of claim 6, the length of the base pipe member including the base elastic support portion is longer than the length of the tip pipe member including the tip elastic support portion. Therefore, the length of the base pipe member including the base elastic support portion can be increased without extending the length from the base elastic support portion to the tip elastic support portion. This ensures sufficient grip width when gripping the base pipe member to store energy in the coiled elastic device, thereby improving the workability of the operation. Furthermore, according to the invention of claim 7, the end of the tip-side elastic receiving portion on the binding ring side is formed in a spherical shape and has a wire through-hole in its center through which the wire extension portion passes. Since the wire through-hole is an elongated hole that extends along the spherical surface, the bending operation of the wire extension portion relative to the base material is facilitated by the movement of the wire along the elongated hole.

[Figure 10] This is a side view of the main part showing the mechanism for adjusting the operating sensitivity of a snare trap. [Modes for carrying out the invention]

[0008] [Basic configuration of a snare trap] The embodiments of the present invention will be described below with reference to the drawings. In the drawings, 1 is a snare trap, and the snare trap 1 comprises a rectangular cylindrical base material 2, a wire 3 having an attachment portion 3a formed at its base end for detachably attaching to a fixed member X such as a standing tree near the animal capture site, and a snare ring 3b formed at the tip of a wire extension portion 2c extending from the base end for snare operation, a coil-shaped elastic device 4 through which the snare ring portion 3b side of the wire extension portion 3c passes and which stores energy to perform the snare operation of the snare ring portion 3b, and a vertically moving automatic mechanism attached to the base material 2 The device comprises a rectangular plate 5 that is shaped like a square plate and is designed to be loosely fitted (internally fitted) in its current state, and which moves downward when stepped on (stepped on) by the animal's leg Y, and a pair of U-shaped (curved) operating members 6 that have a straddle portion 6a and two leg portions 6b, with the tip edges of the two leg portions 6b having openings. The pair of operating members 6 are pivotally supported so that the tip edges of the leg portions 6b can swing up and down relative to the plate 5 via a support shaft 6c, with the openings facing each other. A detailed explanation of these components follows below.

[0009] The footplate 5 is positioned in a waiting position where its upper surface 5a is approximately flush with the upper edge 2c of the base material 2, by a stopper material 8 inserted so as to protrude into the base material 2 through a through hole 2b provided in the peripheral surface 2a of the base material 2. When the footplate 5 is stepped on by an animal's leg Y from this position, the stopper material 8 breaks (cuts), causing the footplate 5 to move downward inside the base material 2. Incidentally, the stopper material 8 is made of an easily breakable rod such as a toothpick or a matchstick.

[0010] Furthermore, at the longitudinal center of the pair of long sides 5b of the tread plate 5, the base piece 7a of the holding member 7 is attached via screws 7aa. At the vertical piece 7b of the holding member 7, the tip of the leg piece 6b of the operating member 6 is pivotally supported via a support shaft 7c so that the openings of the two operating members 6 face each other. And the operating member 6 whose leg piece 6b is pivotally supported by the tread plate 5 by the support shaft 7b is such that, in the state where the tread plate 5 is maintained in the standby position by the stopper member 8, the straddle piece 6a abuts and is supported by the upper edge 2c of the base material 2. In this standby state, the operating member 6 in the state where the straddle piece 6a is supported by the upper edge 2c of the base material 2 is in an inclined state where the support shaft 6c is at a higher position and the straddle piece 6a is at a lower position. That is, the operating member 6 is in a state where it has crossed over the fulcrum with respect to the height (position) of the support shaft 6c, with the straddle piece 6a inclined below the height (idea point) of the support shaft 6c.

[0011] Then, the tightening ring 3b expanded against the biasing force of the coil spring 4 is wound (suspended, looped) around the locking groove 6d formed in the operating member 6 in the state where it has crossed over the fulcrum downward like this, and thus the tightening trap 1 is configured to be set in the standby position. In this standby state, the operating member 6 receives the biasing force of the coil spring 4 that biases the wound tightening ring 3b and is biased to further move the straddle piece 6a downward, thereby preventing the operating member 6 in the standby position from accidentally moving upward and causing the straddle piece 6a to cross over the height of the support shaft 6c.

[0012] The tightening trap 1 configured in this way is installed at the capture site in the standby position as shown in Fig. 3 and Fig. 6(a). And as shown in Fig. 6(b), when the leg Y of the animal steps on the tread plate 5, the stopper member 8 receiving the stepping load breaks and the tread plate 5 moves downward with respect to the base material 2. In conjunction with this downward movement, the operating member 6, as shown in Fig. 6(c), will move downward with the support shaft 7c and the relative height of the straddle piece 6a with respect to the support shaft 7c will move upward beyond the fulcrum to a higher position, and thereby the tightening ring 3b will be instantaneously released in a state of being reduced under the biasing force of the coil spring 4 to trap the leg Y.

[0013] [Characteristic Structure of the Snare Trap] Next, the characteristic structure of the snare trap 1 will be described with reference to the drawings. The snare trap 1 includes a base - side spring receiver 11 that receives and supports the base end portion of the coil - shaped spring 4, a tip - side spring receiver 12 that receives and supports the tip end portion of the coil - shaped spring 4, as members mounted through - hole - like on the wire 3, a base - side pipe member 13 that extends from the base - side spring receiver 11 toward the tip - side spring receiver 12 with the base - end side of the coil - shaped spring 4 fitted therein, a tip - side pipe member 14 that extends from the tip - side spring receiver 12 toward the base - side spring receiver 11 with the tip - end side of the coil - shaped spring 4 fitted therein, a washer 15 interposed between the tip - side spring receiver 11 and the snare ring 3b, and a stopper 16 that fixes the position of the base - side spring receiver 11 with respect to the wire 3.

[0014] The stopper 16 includes a cylindrical portion 16a slidably mounted on the wire 3 and a wing - screw 16b screwed into the cylindrical portion 16a facing in a direction perpendicular to the wire 3. When energizing the coil - shaped spring 4, after moving the base - side spring receiver 11 and the base - side pipe member 13 along the wire 13 to the tip - side to compress the coil - shaped spring 4, the wing - screw 16b is screwed in with the stopper 16 abutted against the base - side spring receiver 11 to fix the stopper 16 with respect to the wire 3. As a result, the base - side spring receiver 11 is restricted from moving toward the base - side along the wire 3 by the stopper 16, and the coil - shaped spring 4 is maintained in an energized state.

[0015] As shown in FIGS. 3 and 9, the base - side pipe member 13 and the tip - side pipe member 14 have a gap A between their opposing edge portions in a state where the coil - shaped spring 4 is energized. And the exposed portion 4a of the energized coil - shaped spring 4 that is exposed from the gap A between the edge portions is configured to be bendable together with the wire extension portion 3c. According to such a configuration, while the energized coil - shaped spring 4 is covered by both pipe members 13 and 14 and is less likely to be affected by the external environment, the bent arrangement of the energized coil - shaped spring 4 (including the wire extension portion 3c and both pipe members 13 and 14) is made possible, and the degree of freedom in installing the snare trap 1 can be increased.

[0016] The gap A should preferably be 5 to 10 cm. This allows the charged coil-shaped projectile 4 to be bent vertically or folded, further increasing the flexibility in setting up the snare trap 1. However, if the gap A exceeds 10 cm, the exposed area of ​​the charged coil-shaped projectile 4 becomes unnecessarily large, potentially making it more susceptible to external environmental influences.

[0017] As shown in Figures 7 and 8, the end of the tip-side elastic receiving portion 12 on the side of the binding ring portion 3b is formed in a spherical shape and has a wire through-hole 12a in its center through which the wire extension portion 3c passes. This wire through-hole 12a is an elongated hole that extends along the spherical surface. With such a tip-side elastic receiving portion 12, the bending operation of the wire extension portion 3c relative to the base material 2 becomes easier due to the movement of the wire along the elongated hole.

[0018] The base material 2 of this embodiment has a rectangular tubular shape with a pair of opposing side portions 2d and a pair of opposing side portions 2e. The tip-side elastic receiving portion 12 of the wire extension portion 3c extends from the binding ring portion 3b, and the extension base end extends out of the base material 2 in a bendable state from a recessed groove portion 2f provided in the widthwise central portion of one of the side portions 2d.

[0019] As shown in Figure 9(a), the tip pipe member 14 is set to a length such that when the wire portion extending from the groove portion 2f of the wire extension portion 3c is bent along one side portion 2d, the tip edge reaches the corner portion of the base material 2 on the bent side. In addition, the base pipe member 13 can be positioned along the other side portion 2e by bending the charged coil-shaped elastic device 4 at the corner portion. With this configuration, the tip pipe member 14 and the base pipe member 13 can be arranged in a bent shape around the perimeter of the base material 2, further increasing the degree of freedom in setting up the snare trap 1.

[0020] Furthermore, the length of the tip pipe member 14 to the corner portion is not long enough to reach one corner portion of the base material 2, and it is desirable that the base pipe member 13 be arranged so as to follow the other side 2e when the coil-shaped elastic 4 curves at the corner from one side portion 2d to the other side portion 2e. In this way, when arranging the tip pipe member 14 and the base pipe member 13 in a bent shape around the perimeter of the base material 2, it becomes possible to position the tip pipe member 14 and the base pipe member 13 closer to the base material 2.

[0021] The installation posture of the snare trap 1 is not limited to that shown in Figure 10(a). For example, as shown in Figure 10(b), the tip pipe member 14 and the base pipe member 13 may be folded and overlapped during installation. Furthermore, the bending direction of the tip pipe member 14 and the base pipe member 13 is not limited to the horizontal direction, as shown in Figures 10(a) and (b), but may also be bent vertically during installation. For example, as shown in Figure 10(c), when installing the snare trap 1 on a slope with an inclination angle that is not constant, the tip pipe member 14 and the base pipe member 13 can be bent relatively vertically to allow installation along the slope.

[0022] The length B of the grippable portion of the base end pipe member 13, including the base end elastic device receiving portion 11, should preferably be set to 8.5 to 15 cm, exceeding the average hand width of an adult male, which is 8.3 cm. This ensures sufficient grip width when gripping the base end pipe member 13 to store energy in the coil-shaped elastic device 4, thereby improving the workability of the operation.

[0023] Furthermore, it is desirable that the length B of the base pipe member 13, including the base elastic support portion 11, be longer than the length C of the tip pipe member 14, including the tip elastic support portion 12. In this way, the length B of the base pipe member 13, including the base elastic support portion 11, can be increased without extending the length from the base elastic support portion 11 to the tip elastic support portion 12, thereby ensuring a sufficient grip width when gripping the base pipe member 13 to store energy in the coil-shaped elastic device 4.

[0024] Furthermore, a protruding portion 2g is provided at the center of the other side 2e of the base material 2. This protruding portion 2g is provided so that the outer end of the operating member 6 does not protrude further outward than the base material 2. In other words, if an animal steps on the outer end of the operating member 6 that protrudes further outward than the base material 2, the snare trap 1 may malfunction, and the protruding portion 2g is provided to prevent such malfunction.

[0025] Although not shown in the illustration, the snare trap 1 of this embodiment is provided with a flexible connecting member (for example, a string or wire) that connects the base material 2 and the treadle 5. This connecting member can prevent the loss of the base material 2 and the treadle 5 by connecting them, but if an animal captured in the snare trap 1 struggles, the connecting member may become entangled in the animal's legs. Therefore, in the snare trap 1 of this embodiment, it is possible to choose whether or not to include the connecting member. This allows the trap to be used in situations where preventing loss is the priority and situations where preventing entanglement is the priority.

[0026] Furthermore, the snare trap 1 of this embodiment is equipped with an operating sensitivity adjustment means for adjusting the operating sensitivity. Specifically, as shown in Figure 10, the operating sensitivity adjustment means of this embodiment is an adjustment plate 21 selectively provided between the footplate 5 and the holding member 7, and the operating sensitivity of the snare trap 1 is adjusted based on the presence or absence and number of these adjustment plates 21. For example, increasing the number of adjustment plates 21 increases the height of the support shaft 6c, and consequently the angle at which the operating member 6 crosses the fulcrum increases, so the load required for the operation of the operating member 6 increases. On the other hand, decreasing the number of adjustment plates 21 decreases the height of the support shaft 6c, and consequently the angle at which the operating member 6 crosses the fulcrum decreases, so the load required for the operation of the operating member 6 decreases. With such an operating sensitivity adjustment means, it becomes possible to arbitrarily adjust the operating sensitivity of the snare trap 1 according to the type and weight of the animal to be captured.

[0027] [Effects of the Embodiment] According to this embodiment configured as described, the base material 2 is installed at the animal capture site, the foot plate 5 is provided on the base material 2 so as to be able to move up and down and moves downward when stepped on by the animal's leg Y, and the pair of operating members 6 have a curved shape with a straddle portion 6a and two leg portions 6b, with an opening formed on the tip side, and with the openings facing each other, the tip edges of the two leg portions 6b are pivotally supported on the foot plate 5 via a support shaft 6c so as to be able to swing up and down, and the base end is attached to a fixing member X near the capture site, and the base end The device includes a wire 3 with a binding loop portion 3b formed at the tip of the wire extension portion 3c that extends from the main shaft, a coil-shaped elastic device 4 through which the binding loop portion 3b side of the wire extension portion 3c passes and which stores energy to perform the binding operation of the binding loop portion 3b, and a base-side elastic device receiving portion 11 and a tip-side elastic device receiving portion 12 that receive and support the base end and tip end of the coil-shaped elastic device 4, respectively, and the binding loop portion 3b, which is expanded against the stored energy of the coil-shaped elastic device 4, has a straddle portion 6a that is lower than the support shaft 6c. In a snare trap 1, which is configured to capture the animal's leg Y by releasing it from the operating member 6 that swings in response to the downward movement of a pivot shaft 6c linked to the animal's leg Y stepping on the footplate 5, the base end elastic device receiving part 11 and the tip end elastic device receiving part 12 have a charged coil-shaped elastic device 4 fitted into them, and the base end pipe member 13 and the tip end pipe member 14 extending from the base end elastic device receiving part 11 and the tip end elastic device receiving part 12 face each other. The coil-shaped elastic device 4, which is provided with a gap A between its edges, is configured such that the exposed portion 4a that is exposed through the gap A between the edges is bendable together with the wire extension portion 3c. This allows the coil-shaped elastic device 4 to be covered by both pipe members 13 and 14 to reduce the influence of the external environment, while also allowing the coil-shaped elastic device 14 (including the wire extension portion 3c and both pipe members 13 and 14) to be bent, thereby increasing the degree of freedom in setting up the snare trap 1.
