Utility model registration No. 3207491

In order to increase the capture rate of prey, it is desirable to reduce the diameter of the ring portion of the wire at a higher position.
In conventional tying traps, in order to reduce the diameter of the wire loop (24) at a higher position, the guide arm (34) is lengthened so that the height of the wire when the guide arm (34) rotates is reduced. need to be higher.
However, if the guide arm is lengthened, the length of the wire attached along the outer periphery of the guide arm, that is, the length of the loop, must also be lengthened.
In this case, it takes time for the ring part to contract in diameter, and the time required to restrain the prey's legs tends to be delayed, making it impossible to necessarily improve the capture rate.

Therefore, one of the problems to be solved by the present invention is to provide a tying trap that can increase the capture rate by rapidly reducing the diameter of the ring at a higher position.

Furthermore, in the conventional tie traps described above, no particular consideration was given to the operation of the treadle.

Therefore, one of the problems to be solved by the present invention is to provide a trap that can increase the catch rate by appropriately controlling the operation of the treadle.

Further, in the conventional tying trap described above, no particular consideration was given to the arrangement of the biasing means.

Therefore, one of the problems to be solved by the present invention is to provide a tying trap that can increase the capture rate by appropriately arranging the biasing means.

In order to solve the above problems, the trap of the present invention is as follows:
A frame and
A tread that is disposed in the frame so that it can be lowered,
On this tread, they are arranged opposite each other so as to form an annular shape in a plan view, and each is supported so as to be able to rotate upward from the periphery of the tread, and when the tread descends and comes into contact with the frame, the tread moves upward. Rotating first and second guide arms;
The ring portion is attached along the outer periphery of the first and second guide arms, and has a ring portion that detaches from the first and second guide arms and reduces its diameter when the first and second guide arms rotate toward the top of the treadle. wire and
a biasing means for biasing the ring portion of the wire to reduce its diameter;
It is a trap with a
The rotation fulcrum of the first guide arm is arranged on the inner side of the second guide arm than the rotation fulcrum of the second guide arm,
The pivot point of the second guide arm is arranged on the inner side of the first guide arm than the pivot point of the first guide arm.

This trap is
A frame and
A tread that is disposed in the frame so that it can be lowered,

Rotating first and second guide arms;
The ring portion is attached along the outer periphery of the first and second guide arms, and has a ring portion that detaches from the first and second guide arms and reduces its diameter when the first and second guide arms rotate toward the top of the treadle. wire and
a biasing means for biasing the ring portion of the wire to reduce its diameter;
The basic operation is as follows. This basic operation is the same as that of the conventional tying trap described above, but will be explained here just in case.

<Basic movements>
With the first and second guide arms spread out over the treadle, a loop of wire is set along the outer periphery of the first and second guide arms, and the set treadle is set inside the frame. Set a trap in this state.
Then, when the prey's foot steps on the treadle within the first and second guide arms, the treadle descends, and in the process, both or either of the first and second guide arms contact the frame and move upward. When the ring is rotated, the ring becomes detached from the first and second guide arms due to the diameter-reducing force applied to the ring by the biasing means, and the ring quickly contracts in diameter to restrain the legs of the prey.

According to the trap of this invention,
The rotation fulcrum of the first guide arm is arranged on the inner side of the second guide arm than the rotation fulcrum of the second guide arm,
Since the rotational fulcrum of the second guide arm is arranged on the inner side of the first guide arm than the rotational fulcrum of the first guide arm,
When the first guide arm and the second guide arm rotate upward, the first guide arm and the second guide arm rotate upward in a crossed state when viewed from the axial direction of the rotation fulcrum.

Therefore, even if the guide arm is lengthened to reduce the diameter of the loop of the wire at a higher position, the length of the wire attached along the outer circumference of the guide arm, that is, the loop The length can be shortened.
Therefore, the time required to reduce the diameter of the ring can be shortened accordingly, and the legs of the prey can be restrained quickly, so that the capture rate can be improved.

As described above, according to the tying trap of the present invention, the capture rate can be increased by quickly reducing the diameter of the ring at a higher position.

In addition, in order to solve the above problems, the binding trap of the present invention includes:

Since it is equipped with
The tilting of the tread when the tread is stepped on by prey and moves downward is regulated.
When the treadle is stepped on by the prey and moves downward, the greater the tilting of the treadle, the greater the direction in which the first and second guide arms spring up, and as a result, the radial position of the ring becomes lower, reducing the capture rate. It gets lower.
In contrast, according to the present invention, since the tilting of the footboard when the footboard is stepped on by the prey and moves downward is restricted, the tilting of the first and second guide arms in the upward direction is reduced.
As a result, the diameter reduction position of the ring becomes higher and the capture rate also increases.

That is, according to the tying trap of the present invention, by controlling the treadle as described above, it becomes possible to reduce the diameter of the loop at a higher position, and as a result, the capture rate can be increased.

The insertion hole is provided with two or more holes having different distances between the inner end of the frame in the insertion hole into which the support rod is inserted and the support portion of the treadle by the support rod at each of the installation locations. Therefore, if the hole to be inserted is different, the distance between the inner end of the frame and the part where the treadle is supported by the support rod will be different, and the moment acting on the support rod will also be different.
This makes it possible to adjust the timing of the downward movement of the tread according to the load that causes the tread to move downward, that is, the size of the prey, and the diameter of the ring is reduced at the appropriate timing according to the size of the prey. It becomes possible to do so. As a result, it becomes possible to increase the capture rate.

It is attached along the outer periphery of the first and second guide arms 10 and 20, and when the first and second guide arms 10 and 20 rotate toward the top of the footboard 40 (see FIG. 6), the first and second guide arms 10 and 20 are attached. 2. A wire 50 (see FIG. 7) having a ring portion 51 whose diameter decreases when removed from the two guide arms 10 and 20;
a biasing means 60 that biases the ring portion 51 of the wire 50 to reduce its diameter;
It is equipped with

As shown in FIGS. 5 and 6, this binding trap 1 is
The rotation fulcrum 11 of the first guide arm 10 is arranged on the inner side of the second guide arm 20 (left side in FIG. 5(a)) than the rotation fulcrum 21 of the second guide arm 20,
The rotation fulcrum 21 of the second guide arm 20 is arranged on the inner side of the first guide arm 10 (on the right side in FIG. 5(a)) than the rotation fulcrum 11 of the first guide arm 10.

This tying trap 1 includes the frame body 30, the step board 40, the first and second guide arms 10, 20, the wire 50 having the ring portion 51, and the biasing means 60, as described above. Therefore, the basic operation is as follows. This basic operation is the same as that of the conventional tying trap described above, but will be explained here just in case.

<Basic movements>
As shown in FIG. 2, with the first and second guide arms 10 and 20 spread out on the footboard 40, the loop portion 51 of the wire 50 is inserted along the outer periphery of the first and second guide arms 10 and 20. (see FIG. 2(b)), and set the set footboard 40 inside the frame. Set a trap in this state.

Thereafter, when the prey's feet (not shown; the same applies hereinafter) step on the treadle 40 within the first and second guide arms 10 and 20, the treadle 40 descends, and in the process, the first and second guide arms 10 and 20 . 51 comes off from the first and second guide arms 10 and 20 (see FIG. 6), and the ring portion 51 suddenly contracts in diameter to restrain the legs of the prey (not shown).

According to this binding trap 1, as shown in FIGS. 5 and 6,
The rotation fulcrum 11 of the first guide arm 10 is arranged on the inner side of the second guide arm 20 than the rotation fulcrum 21 of the second guide arm 20,
Since the rotational fulcrum 21 of the second guide arm 20 is arranged on the inner side of the first guide arm 10 than the rotational fulcrum of the first guide arm 10,
When the first guide arm 10 and the second guide arm 20 rotate upward, the first guide arm 10 and the second guide arm 20 rotate upward in a crossed state as shown in FIG. Become.

Therefore, even if the guide arms 10 and 20 are lengthened to reduce the diameter of the ring portion 51 of the wire 50 at a higher position, the outer periphery of the guide arms 10 and 20 is It is possible to shorten the length of the wire attached along the ring portion 51, that is, the length of the loop portion 51.

Therefore, the time required to reduce the diameter of the ring portion 51 can be shortened accordingly, and the legs of the prey can be quickly restrained, so that the capture rate can be improved.

As described above, according to this tying trap 1, the capture rate can be increased by quickly reducing the diameter of the ring portion 51 at a higher position.

As shown in FIG. 8, the first guide arm 10 has a substantially arcuate shape in plan view, and both ends 12, 12 of the first guide arm 10 are connected to a plate-shaped support portion 43 (FIG. 5, 11) is rotatably supported. A wire guide groove 13 is formed in the curved portion of the first guide arm 10 .

As shown in FIG. 9, the second guide arm 20 has a substantially arcuate shape in plan view, and both ends 22, 22 of the second guide arm 20 are connected to a plate-shaped support portion 43 (FIG. 5, 11) is rotatably supported. A wire guide groove 23 is formed in the curved portion of the second guide arm 20 .

This binding trap 1 has a tread control means for controlling the operation of the tread plate 40, and this tread control means, as shown in FIGS. 3(c) and 3(d),
a tread-side contact portion 42 that is provided on the tread plate 40 and regulates the tilting of the tread plate 40 when the tread plate 40 moves downward when stepped on by prey;
a frame-side contact portion 32 that is provided on the frame 30 and restricts the tilting of the footboard 40 by coming into contact with the footboard-side contact portion 42;
It is equipped with

According to this tying trap 1, the tilting of the footboard 40 when the footboard 40 moves downward when stepped on by the prey is regulated.
When the footboard 40 is stepped on by the prey and moves downward, when the tilting of the footboard 40 becomes large, the direction in which the first and second guide arms 10 and 20 spring up is tilted greatly, and as a result, the diameter reduction position of the ring portion 51 is also lowered. As a result, the catch rate will be lower.

On the other hand, according to this tied trap, since the tilting of the footboard 40 when the footboard 40 is stepped on by the prey and moves downward is restricted, the tilting of the first and second guide arms 10 and 20 in the upward direction is restricted. becomes smaller.
As a result, the diameter reduction position of the ring portion 51 becomes higher, and the capture rate also becomes higher.

That is, according to this tied trap, by controlling the step board 40 as described above, it becomes possible to reduce the diameter of the ring portion 51 at a higher position, and as a result, the capture rate can be increased.

Further, the tread control means, as shown in FIGS. 1(c) and 4(e) and 4(b) and (c),
Support rods (for example, It has an insertion hole 36 into which a toothpick (toothpick) 35 is inserted.

At each installation location 34, as shown in FIG. 4(d), this insertion hole 36 is connected to the inner end 36b of the frame 30 in the insertion hole into which the support rod 35 is inserted and the support portion of the footboard 40 by the support rod 35. Two or more holes are provided at different distances from the hole 35b. In the illustrated example, a total of nine holes 361 to 369 are provided for one installation location 34, and among them, the inner ends 36b of the holes 361, 364, and 367 and the support portion 35b of the footboard 40 by the support rod 35. The distance between the inner ends 36b of the holes 362, 365, 368 and the support portion 35b of the treadle 40 by the support rod 35 is L2, and the distance between the inner ends 36b of the holes 363, 366, 369 and the support rod 35. The distance between the footboard 40 and the support portion 35b is L3.

According to this binding trap, it is provided at three or more installation locations 34 (four locations in the figure) in the inner circumferential direction of the frame 30, supports the treadle 40 from below, and uses a predetermined downward force of the treadle 40. Since it has an insertion hole 36 into which the breakable support rod 35 is inserted, when the prey steps on the footboard 40, it is supported by the support rod 35 until the support rod 35 breaks (Fig. 4(b), (c)). Reference) The footboard 40 does not move downward, but moves downward when the support rod 35 breaks.

The insertion hole 36 has a different distance between the inner end 36b of the frame 30 in the insertion hole 36 into which the support rod 35 is inserted and the support portion 35b of the treadle 40 by the support rod 35 at each of the installation locations 34. Since two or more holes are provided for the insertion, if the holes to be inserted are different, the distance between the inner end (36b) of the frame 30 and the support part 35b of the treadle 40 by the support rod 35 will be different. The moments acting on 35 will also be different.

This makes it possible to adjust the load F at which the treadle 40 moves downward (see FIG. 4(c)), that is, the timing at which the treadle 40 moves downward, depending on the size of the prey. Therefore, it becomes possible to reduce the diameter of the ring portion 51 at an appropriate timing. As a result, it becomes possible to increase the capture rate.

That is, according to this tying trap, by controlling the step board 40 as described above, it is possible to select the activation timing according to the size of the prey, thereby increasing the capture rate.

In other words, it is possible to selectively move the footboard down depending on the size of the prey, allowing you to target a wide range of animals from small to large, or selectively target large animals. This means that selective capture will become possible.

Furthermore, two or more insertion holes 36 (three in the figure) are provided in the vertical direction of the frame 30. As shown in FIG. 4, holes 361, 362, 363 are provided at the top, holes 364, 365, 366 are provided at the second height, and holes 367, 368, 369 are provided at the third height. .

With this configuration, since two or more insertion holes 36 are provided in the vertical direction of the frame body 30, when the prey steps into this trap, the depth of the step until it reaches the treadle 40 can be changed. I can do it.

In this embodiment, by inserting the support rod 35 into the top hole 361, 362, or 363, the depression depth is set to D1 (FIG. 4(e)), and the second height hole 364, 365, or By inserting the support rod 35 into the hole 366, the depth of depression can be set to D2, and by inserting the support rod 35 into the hole 367, 368, or 369 at the third height, the depth of depression can be set to D3.

That is, according to this trap, by controlling the step board 40 as described above, the depth of the step can be changed depending on the condition of the ground on which the trap is set. This makes it possible to reduce the vigilance given to the prey, and as a result, it is possible to increase the capture rate.

For example, when installing on comparatively hard ground that has been trodden down, the uppermost tread depth is set to D1. Conversely, when installing on soft ground where fallen leaves are piled up, the lowest step depth is set to D3. Further, when installing on intermediate soft ground, the depression depth of the intermediate portion is set to D2.

In this way, it is possible to make it difficult for the prey to feel the difference between the softness of other surfaces when stepping on the footboard 40, to reduce the wariness given to the prey, and to increase the capture rate. .

The biasing means 60, as shown in FIGS. 6 and 7,
a diaphragm member 61 that slides on the wire 50 so as to squeeze the ring portion 51 of the wire 50 that has come off the first and second guide arms 10 and 20;
a spring 62 that biases the aperture member 61 in the direction of constricting the ring portion 51 (direction of arrow S1 in FIG. 6);
A storage pipe 63 that stores the spring 62;
Equipped with
The frame 30 has a pedestal portion 37 (see FIGS. 7 and 5) that protrudes to the outside of the frame 30 and supports the storage pipe 63.

With this configuration, the frame 30 has the pedestal part 37 that protrudes outside the frame 30 and supports the storage pipe 63, so by supporting the storage pipe 63 with the pedestal part 37, the storage pipe 63 can be easily stored. The diaphragm member 61 sliding on the wire 50 can be biased upward at the center of the footboard 40 by the biasing force of the spring 62 protruding from the pipe 63.

For this reason, it becomes possible to reduce the diameter of the ring portion 51 of the wire 50 at a higher position, and as a result, the capture rate can be improved.

The aperture member 61 of this embodiment includes a tip ring 61c that squeezes the wire, a head 61h that presses the tip ring 61c, and a spring 61s as a buffer provided between the tip ring 61c and the head 61h. have. The head 61h is integrally provided with a guide tube 61t through which the wire 50 is passed.

As shown in FIGS. 7 and 5, the edge 38 of the frame 30 that comes into contact with the spring 62 that slides the aperture member 61 is an inclined surface.

With this configuration, when the head 61h and the spring 62 protrude from the storage pipe 63, the head 61h and the spring 62 are less likely to come into contact with the edge of the frame 30.

Even if they make contact, the edge 38 of the frame 30 is an inclined surface, so the resistance of the edge 38 of the frame 30 to the head 61h and the spring 62 is reduced.
Therefore, the speed of the aperture member 61 sliding on the wire 50 can be increased.

Therefore, the diameter reduction speed of the ring portion 51 of the wire 50 can be increased, and as a result, the capture rate can be improved.

As shown in FIGS. 1 and 11, this binding trap 1 has a lock structure (lock mechanism) 70 that restricts the operation of the trap 1 by restricting the downward movement of the footboard 40.

With this configuration, the trap can be temporarily disabled.

As shown in FIG. 11(b), the locking mechanism 70 mainly includes a knob 71, a cross key 72 integrated with the knob 71, and a cross key 72 connected to the cross key 72 via a height adjustment bolt nut 73. A locking body 75 having a grounding body 74 is provided. The grounding body 74 has the same shape as the cross key 72 in plan view.

On the other hand, as shown in FIG. 3, a cross recess 44 through which the grounding body 74 and the cross key 72 can pass is provided in the center of the footboard 40.

Therefore, for example, as shown in FIG. 2, when the lock body 75 is removed from the footboard 40, the footboard 40 can be lowered and the trap can be activated.
On the other hand, as shown in FIGS. 1 and 11, after passing the grounding body 74 of the lock body 75 and the cross key 72 through the cross recess 44, the knob 71 is rotated 45 degrees to attach the lock body 75 to the footboard 40. When the trap is attached and the grounding body 74 is brought into contact with the ground, the step board 40 is prevented from descending, and the trap becomes inoperable.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and can be modified as appropriate within the scope of the gist of the present invention.
