The safety pin 5e has a screw portion 5ea that is screwed into the screw hole 5a at the lower end portion of the metal bar, and a handle portion 5eb that can be put on the upper end portion is curved, and an insertion hole is formed in the middle portion. A stopper portion 5ec having a diameter larger than 5c is provided, and has a length that protrudes upward considerably longer than the movable portion 3c of the narrowing member 3 in a state of being inserted into the insertion hole 5c and screwed into the screw hole 5a. ing.

  The stepping hole cylinder 6 is formed of a synthetic resin material in a cylindrical shape, has an inner diameter substantially the same as the diameter of the stepping plate 1, and is provided with a narrow notch 6a downward from the upper edge. The lower end edge of the notch 6a is a flat seat 6b. The notch 6a allows the arm 4b of the response member 4 to be inserted from the outside. The receiving flange 6e of the narrowing member 3 is locked to the seat 6b.

  The first insertion hole 7 is formed by a hole drilled in the stepping hole cylinder 6, has a diameter through which the pin-like object 9 is inserted, and faces the notch 6 a of the stepping hole cylinder 6. One is arranged near the upper end of the position.

  The second insertion hole 8 is made of a hole drilled in the stepping hole cylinder 6, and has a diameter through which the pin-like object 9 is inserted, and an upper end portion at a position away from the first insertion hole 7. Six pieces are arranged radially in the vicinity. The drilling position of the second insertion hole 8 is set higher than the first insertion hole 7 by the thickness of the tread board 1.

  The pin-like object 9 is made of a material that is broken by a slight load, and has a length that is inserted into the first insertion hole 7 and the second insertion hole 8 and abuts on the upper and lower surfaces of the tread board 1. ing. For the pin-like material 9, a toothpick is specifically preferable.

  The rod-like object 10 is made of a material having a certain degree of flexibility with respect to a load, and is pierced into the soil inside the wire 2 that is spread out in a loop around the step-through hole cylinder 6. . For this rod-shaped object 10, a bamboo skewer is specifically preferable.

  The wire fixing member 11 is made of a wire or the like, and has a length that can be attached to the upper end portion in the vicinity of the notch portion 6a of the pedal hole cylinder 6 and can be entangled with the loop-shaped portion of the wire 2. .

  In order to install this form, a step-out hole H for accommodating the entire step-through hole cylinder 6 and the narrowing member 3 and the like is dug in the beast path and the like. Then, after the stepping hole cylinder 6 is installed in the stepping hole H, the wire 2, the narrowing member 3, the response member 4, and the safety mechanism 5, which are assembled in advance, are installed inside and outside the stepping hole cylinder 6. Install in.

  At this time, the diameter of the wire 2 is adjusted by adjusting the position of the restriction stopper 2b of the wire 2 so that animals (eg, birds, rabbits) smaller than the small animals to be captured are not pinched. Then, the wire 2 is expanded in a loop shape, the insertion length of the wire 2 into the narrowing member 3 is adjusted and fixed with the fixing screw 3d of the narrowing member 3, and the narrowing member 3 is used for the step-through hole. The pushing-in locking flange 3e is locked to the receiving seat 6b of the step-out hole cylinder 6 so as to be positioned upright by being positioned at the notch 6a of the cylinder 6. That is, the locking flange 3e of the narrowing member 3 and the seat 6b of the stepping hole cylinder 6 function as a positioning structure between the narrowing member 3 and the stepping hole cylinder 6.

  As a result, the arm 4 b of the responding member 4 assembled to the narrowing member 3 extends into the inside of the stepping hole cylinder 6, and the receiving plate 4 c is horizontally supported inside the stepping hole cylinder 6. It can be said that this state is maintained by the safety mechanism 5 rather than the engagement of the lock pin 4d and the lock groove 4e of the response member 4. That is, the screw part 5ea of the safety pin 5e of the safety mechanism 5 is screwed into the screw hole 5a of the flange 5b attached to the casing 3b of the narrowing member 3, and the stopper part 5ec is attached to the movable part 3c of the narrowing member 3. By pressing the flange 5d, the casing 3b and the movable portion 3c are prevented from being detached against the elastic pressure of the coil spring 3a of the narrowing member 3.

  Thereafter, after the pin-like object 9 is inserted into the first insertion hole 7, the tread plate 1 is dropped into the inside from the upper end opening of the cylinder 6 for the step-through hole.

  As a result, the tread plate 1 is abutted and supported by the receiving plate 4 c of the responding member 4 and the pin-like object 9 inserted through the first insertion hole 7 and is supported near the upper end inside the tread hole cylinder 6. The

  Thereafter, the pin-like object 9 is inserted into the second insertion hole 8.

  As a result, the tread plate 1 has a pin shape in which the upper surface is inserted into the second insertion hole 8 except where it is supported by the receiving plate 4c of the responding member 4 and the pin-like object 9 inserted through the first insertion hole 7. The object 9 is pushed down by the object 9 to prevent the tread 1 from being attached to the grab and the horizontal posture is stabilized.

  Thereafter, the wire fixing member 11 is entangled along the outer periphery so that the loop-shaped portion of the wire 2 does not protrude from the inner peripheral side of the step-out hole cylinder 6 to prevent the wire 2 from being lifted. About two rod-like objects 10 are pierced substantially vertically between the loop-shaped part and the cylinder 6 for the step-through hole.

  At this time, the puncture position of the rod-like object 10 is set on the side away from the narrowing member 3 of the loop-shaped portion of the wire 2. Note that the pin-like object 9 inserted through the first insertion hole 7 and the second insertion hole 8 supports the loop-shaped portion of the wire 2 to prevent sinking.

  Thereafter, the entire opening of the step-out hole H including the tread plate 1 is concealed by the earth and sand for concealment R such as earth and sand, dead leaves, etc., and the knob 5eb of the safety pin 5e of the safety mechanism 5 is picked and rotated to be the safety pin. The installation is completed by pulling out 5e from the screw hole 5a and the insertion hole 5c.

  At this time, since the safety pin 5e of the safety mechanism 5 protrudes longer than the concealment earth and sand R, the turning operation of the safety pin 5e can be easily performed.

  When the safety mechanism 5 is removed, the lock pin 4d and the lock groove 4e of the response member 4 are engaged as shown in FIG. 7, and the space S of the narrowing member 3 is eliminated. At this time, since a mechanical engagement sound is generated from the narrowing member 3 and the responding member 4, the operation of the safety mechanism 5 is confirmed.

  Note that the rear end portion of the wire 2 extending outward from the casing 3b of the narrowing member 3 is concealed with soil, dead leaves, etc., and is wired and fixed to nearby trees and rocks.

  In a state in which this form is installed, the diameter of the tread plate 1 and the inner diameter of the tread hole cylinder 6 are substantially matched, and a patent document is formed between the tread board 1 and the tread hole cylinder 6 (the tread hole H). Since the useless space like the small animal capturing device 1 is not formed, the concealment earth and sand R covering the tread board 1 does not fall and air does not circulate through the space. Therefore, it becomes difficult to be alert to small animals.

  When a small animal steps through this installed form, the tread plate 1 descends in a horizontal state inside the tube 6 for the stepping hole.

  At this time, the load of the small animal applied to the tread board 1 is received over a wide range and at a wide angle by the receiving plate 4c of the responding member 4 and the pin-like object 9 inserted through the first insertion hole 7 and the second insertion hole 8. Even if the load applied to the tread 1 is deviated, the tilt of the tread 1 is prevented and the descent in the horizontal state is ensured. At the same time when the treadle 1 is lowered in the horizontal state, the pin-like object 9 inserted through the first insertion hole 7 is broken, and the treadle 1 is kept in the horizontal state while the treadle 1 is lowered. The pin-like object 9 inserted through the first insertion hole 7 disappears from the inside of the pedal hole cylinder 6. In addition, since the support of the tread 1 is assisted by the pin-like object 9 inserted into the first insertion hole 7, the operation of the tread 1 that is more sensitive than necessary is avoided. In addition, it is possible to prevent the response member 4 from operating due to a small animal stepping down or a falling object such as a tree nut.

  The lowered tread 1 pushes down the receiving plate 4c of the response member 4. The receiving plate 4c of the responsive member 4 that has been pushed down is tilted about the support shaft 4f via the arm 4b.

  At this time, since the receiving plate 4c of the responding member 4 is rotatably supported by the bearing 4g provided at the tip of the arm 4b, it is assumed that a slight inclination occurs in the tread 1 that descends due to a load deviation or the like. Also, the receiving plate 4c rotates to reliably tilt in response to the tilt.

  The tilt of the arm 4b of the responding member 4 causes the lock groove 4e to be detached from the lock pin 4d.

  At this time, the supporting shaft 4f of the responding member 4 serving as a fulcrum is provided at the projecting tip of the support plate 4a, and the length of the supporting plate 4c serving as a power point is sufficiently secured. Become sensitive. Further, the rotation stop portion 5f of the safety mechanism 5 abuts on the flange 5d attached to the movable portion 3c of the narrowing member 3, so that the casing 3b of the narrowing member 3 is caused by the tilting stress of the arm 4b of the responding member 4. To prevent the locking groove 4e from being detached from the locking pin 4d of the responding member 4.

  The detachment of the lock pin 4d and the lock groove 4e of the response member 4 causes the narrowing member 3 to start the narrowing operation of the wire 2.

  That is, the movable portion 3c fitted to the casing 3b of the narrowing member 3 moves along the wire 2 under the elastic pressure of the coil spring 3a when the lock pin 4d and the lock groove 4e of the responding member 4 are detached. This movement is made instantaneously, and the movable part 3c of the narrowing member 3 jumps up the concealment earth and sand R and protrudes to the ground. The wire 2 is narrowed to the throttle stopper 2b and the foot of the small animal that has stepped through the tread 1 is tied up. It will be.

  The operation of the responding member 4 that relays the operation of the tread plate 1 and the narrowing member 3 is mainly performed in the inside of the tube 6 for the stepping hole, and the operation form like a slide of the small animal capturing device according to Patent Document 1. Therefore, even if earth or sand adheres to the narrowing member 3, there is no obstacle. Accordingly, the smoothness of the operation of the responding member 4 is not impaired, and the speed of the narrowing operation of the wire 2 of the narrowing member 3 is ensured. In addition, as described above, the length of the fulcrum and the power point is set long so that the responsiveness of the responsive member 4 becomes sensitive, which contributes to guaranteeing the speed of the narrowing operation of the wire 2 of the narrowing member 3. To do.

  In the narrowing operation of the wire 2 of the narrowing member 3, as shown in FIG. 11, the rod-like object 10 in which the loop-shaped portion of the wire 2 that is narrowed by the movable portion 3c is pierced outside the step-out hole cylinder 6. Is guided upward. That is, the looped portion of the wire 2 that is narrowed down so as to follow the foot that the small animal senses and pulls up is lifted, and the looped portion of the wire 2 is simply moved sideways to lift the foot. So that it won't be narrowed down in the sky after.

  In addition, when the small animal with the wire 2 tied to the foot rampages, the responding member 4 is tilted along the narrowing member 3 as shown in FIG. The narrowing member 3 and the responding member 4 are not damaged. Therefore, it can be used repeatedly over and over.

  When this form is withdrawn without capturing the small animal, the safety pin 5e of the safety mechanism 5 is inserted into the concealed earth and sand R, the knob 5eb of the safety pin 5e is picked and rotated, and the screw 5ea is The stopper part 5ec is screwed into the screw hole 5a and pressed against the flange 5d attached to the movable part 3c of the narrowing member 3. As a result, the movable portion 3c of the narrowing member 3 is not unexpectedly protruded from the casing 3b. Therefore, the wire 2, the narrowing member 3, the responding member 4, the safety mechanism 5 and the like can be safely taken out from the stepping hole H.

  As described above, in addition to the illustrated form, the pin-like object 9 can be attached to the pedal hole cylinder 6 so that it can be raised and lowered.

  The small animal capturing apparatus according to the present invention may target a wide range of small animals from a very small to a considerably large one by adjusting the diameter of the tread board 1 and the elastic force of the coil spring 3a of the narrowing member 3. it can.
