Hereinafter, an animal threat repaying device 100 according to an embodiment will be described with reference to the drawings.
The animal and animal threatening and paying apparatus 100 includes a deployment unit 101, a sound explosion unit 102, and a trigger unit 103, which will be described in order.

<Development unit 101>
The deployment part 101 is a part that instantaneously deploys the umbrella-shaped bar member 3 along the guide track 1. The guide track 1 is a metal cylindrical rod of about 1 m. In the circumferential direction of the outer peripheral surface of the guide track 1, a plurality (eight in the illustrated example) of rod members 3 are positioned so as to have a radial arrangement centered on the guide track 1. One end 3b of each bar member 3 is attached around the tip of the guide track 1 as a fulcrum, and each bar member 3 can swing in the direction B. In addition, the other end 3c of the bar member 3 is engaged with a bell 5 via a metal ring 4 so as to be swingable.

A link mechanism portion 8 is formed between the guide track 1 and the plurality of rod members 3 to shift the rod members 3 in a radial direction all at once. The link mechanism unit 8 includes a first link member 9, a leading cylinder 10, a second link member 11, and a sliding body 12. One end of the first link member 9 is pivotally attached to an intermediate position 3d of the rod member 3 via a shaft member.

The tip tube 10 is slidably fitted on the guide track 1, and a circle tangential axis 9 a centering on the guide track 1 is provided on the outer periphery of the head tube 10. The other end is pivotally attached so as to be swingable around the shaft 9a. One end of the second link member 11 is pivotally attached to the middle of the length of the first link member 9 by a shaft 11a. The sliding body 12 is slidably fitted on the guide track 1 and is located on the rear side of the guide tube 1 with respect to the top tube 10. The other end of the second link member 11 is pivotally attached to the sliding body 12 by a shaft 11b.

The leading cylinder 10 and the sliding body 12 are connected by a spring 15 fitted on the guide track 1. When the top cylinder 10 and the sliding body 12 are brought close to each other and the spring 15 is compressed, the plurality of rod members 3 operate so as to approach the contracted state around the guide track 1 by the action of the link mechanism portion 8, The sliding body 12 slides rearward on the guide track 1. On the other hand, when the elastic force stored in the spring 15 is released, the space between the leading cylinder 10 and the sliding body 12 opens, and the leading cylinder 10 and the sliding body 12 slide forward on the guide track 1, In addition, the plurality of bar members 3 are caused to move out of the guide track 1 and are expanded.

Further, the connecting members 3d and 3d of the adjacent rod members 3 and 3 are connected by a flexible first string member 16 (FIG. 2). These first string members 16 restrict the plurality of bar members 3 from expanding further beyond the expanded state. And each between the connection places with the 2nd link members 11 and 11 in the adjacent 1st link members 9 and 9 is also couple | bonded by the 2nd string member 17 which can be bent freely. The second string member 17 acts to restrict each first link member 9 from being bent and deformed laterally by the force applied from the second link member 11.

When the sliding body 12 is slid to the rear side on the guide track 1 and comes close to the rear end of the guide track 1, the locking mechanism portion 18 for holding the position of the sliding body 12 in the contracted state is guided. It is formed at an end portion 1 a on the rear end side of the track 1.

The locking mechanism 18 has a locking claw 19 mounted in the guide track 1 and an operation unit 20 for operating the locking claw 19. The locking claw 19 can advance and retreat into and out of the hole b1 of the guide track 1, and is always urged by a spring (not shown) to the side protruding upward from the hole b1.

A push input unit 21 is provided near the front side of the end 1a. The push input portion 21 is coupled to the lower portion of the locking claw 19, and the upper portion of the locking claw 19 is immersed in the guide track 1 when the push input portion 21 is shifted downward by an external force.

According to this locking mechanism portion 18, the locking claw 19 is fitted and locked in the engagement hole b <b> 2 formed in the sliding body 12 by elasticity, and in this state, external force is applied to the push input portion 21. The position holding state of the link mechanism unit 8 is released by the action and the input unit 21 being pushed down.

When the sliding body 12 is shifted rearward on the guide track 1 and comes close to the end 1a, the distance from the leading cylinder 10 to the sliding body 12 is reduced by the configuration of the link mechanism section 8, and the spring 15 is compressed. The Then, when the holding of the position of the link mechanism portion 8 by the locking mechanism portion 18 is released, the spring 15 deforms the rod member 3 into the deployed state by its own elasticity.

The support portion 2 includes an attachment portion 22 and a square pole support rod portion 23. A metal fitting 24 that holds the guide track 1 in a horizontal posture is attached to the top of the attachment portion 22 to fix the end portion 1a. The lower end of the support bar portion 23 is sharp and easy to drive into the ground. The attachment portion 22 is detachably coupled to the side surface of the support rod portion 23 driven into the ground with a bolt or the like.

<Explosion part 102>
In FIG. 2, an explosive portion 102 is disposed at the front end of the guide track 1. The explosive sound part 102 includes a holder 6 fixed to the front part of the guide track 1 and a cover body 27. The cover body 27 has an appropriate waterproof property by pushing the rear end portion into the front end opening of the holder 6, and the firecracker 28 is housed inside the cover body 27.

In FIG. 3, for example, a cone-shaped party cracker is used as the firecracker 28 in FIG. The firecracker holding string 29a is secured to the inner surface of the holder 6 at its proximal end, and an annular portion c1 that is fitted on the outer peripheral surface of the firecracker 28 is formed at the tip. The ignition means 29 is fixed to the moving body 30 mounted on the guide track 1 so as to be movable back and forth by a connecting portion 30b so as to protrude forward from the front portion of the guide track 1.

When the compression of the spring 15 is released and the bar member 3 transitions to the unfolded state, the moving body 30 is pushed and moved forward (left side in the drawing) by the leading cylinder 10. The ignition means 29 is used to tie an ignition string 28 a extended from the firecracker 28.

When the firecracker 28 is stored in the holder 6, the cover body 27 is first removed from the holder 6 while the sliding body 12 is held by the locking function of the locking mechanism 18, and the moving body 30 is appropriately moved. The firecracker 28 is inserted into the annular portion c1 of the firecracker holding string 29a, and the tip of the ignition string 28a is tied to the ignition means 29. Then, the cover body 27 is covered.

When the holding state by the locking mechanism portion 18 is released while the firecracker 28 is housed, the leading cylinder 10 pushes and moves the moving body 30 forward by the elasticity of the spring 15. As a result, the igniting means 29 strikes the cover body 27 forward by the gripping portion 29b and repels it. On the other hand, the ignition string 28a is pulled out from the firecracker 28, and the firecracker 28 is ignited to generate intense explosion sound. When the used firecracker 28 is replaced with a new one and stored, processing similar to that described above is performed.

<Trigger part 103>
In FIG. 1, a trigger unit 103 includes a first input mechanism unit 31 that acts on a tensile force by a pest, and a second input mechanism unit that activates the push input unit 21 in association with the operation of the first input mechanism unit 31. 32.

The first input mechanism 31 has a front-rear support plate 33 in the middle of the length of the support bar 23. The front-rear support plate 33 has an upward protrusion 33a at the front and protrudes downward at the rear. It has the shaft support part 33b made. A swing body 34 is attached to the upward projecting portion 33a. The oscillating body 34 includes a clip 34a and a metal rod 34b extending therefrom, and the clip 34a can be oscillated back and forth via a lateral shaft 35 on an upward projecting portion 33a. The upper end portion of the metal bar 34b is bent sideways, and this upper end portion functions as the opening / closing main part d1. On the other hand, a lateral shaft 36 is fixed to the shaft support portion 33b, and a pulley 37 is rotatably mounted on the lateral shaft 36.

The pulley 37 has a tip connected to an object to which an external force is applied and a tension string 38 is wound around. The tension string 38 is guided downward by the pulley 37 and a tension weight 39 is suspended at the lower end. ing. The tension weight 39 is a water container having a lid that can be opened and closed, and its weight can be arbitrarily changed by changing the amount of water in the water container. The clip 34a is swung about the lateral axis 35 of the rocking body 34 according to the front-rear displacement of the pulling cord 38 by sandwiching an arbitrary position of the horizontal position of the pulling cord 38.

The second input mechanism unit 32 includes a metal container 41 with an upper surface opened, a storage unit 42 disposed immediately above the metal container 41, and a dropping body 43 inserted into the storage unit 42. Yes. The metal container 41 hangs hanging straps 45, 45 from a ring member 44 inserted through the square hole of the push input unit 21, and is suspended from the lower ends of the hanging straps 45, 45. The metal container 41 has a drain hole for removing rain water and the like on the bottom surface.

The storage portion 42 includes a cylindrical body 42a fixed to a support member 46 projecting from the upper side surface of the mounting portion 22, and a lid body 42b that covers the upper end opening of the cylindrical body 42a so as to prevent falling leaf pieces and rainwater from entering. Have. The cylindrical body 42a has an inner diameter of 2 cm and a length of 7 cm, and a cut-out part e1 is formed in the latter half of the lower end edge. The excision part e1 forms a movement path of the opening / closing essential part d1 which is a part of the rocking body 34. When the opening / closing essential part d1 is positioned at the forefront of the excision part e1, the lower end opening of the cylindrical body 42a is closed. When the cylinder 42a is moved rearward from the lower part, it is completely opened. The lid 42b is preferably coupled to the support member 46 with a chain or a string to prevent loss. The distance from the lower end of the storage part 42 to the bottom surface of the metal container 41 is about 50 cm.

When the lower end opening of the cylindrical body 42a is opened by the movement of the opening / closing main part d1, the falling body 43 naturally falls by its own weight, and when it collides with the bottom surface of the metal container 41, a metal impact sound is emitted at the same time. The push input part 21 is pushed down by the impact force of the time, and the plurality of bar members 3 are opened at once.

<Usage example of animal threat surrender device 100>
Next, a usage example of the above-described animal threat surrender device 100 will be described. FIG. 4 is a perspective view showing a use state in which the animal threatening repayment apparatus 100 is in an operation standby state.
A pile 48 is driven into the outer periphery of a plantation or the like that is intended to prevent the invasion of animals such as a cage, and a wire member 47 that is an external force application target such as a wire or string is stretched on the pile 48. In this case, the line member 47 is in a state where it can be moved laterally somewhat.
Then, the animal threat repaying device 100 is installed at a place inside the square frame f1 at intervals of, for example, 10 m along the length direction of the wire member 47. The unfolded state of the bar member 3 drives the support bar part 23 into the ground to be self-supporting and fixes the attachment part 22. It is preferable that each of the animal threatening and retreating devices 100 be close to the state in which the front direction is orthogonal to the line member 47, and the guide track 1 is horizontal so that the bar member 3 is unfolded toward the outer periphery. And

In this state, the rod member 3 is reduced, and the sliding body 12 is held in position by the locking mechanism portion 18. Further, the tension string 38 is connected to the wire member 47 between the piles 48 by a wire 38a. At this time, it is preferable that the wire 38a can be untied when the harmful animal comes into contact with the wire member 47 and an excessive force is applied. In this way, the connection of the front end portion 38a is broken before an excessive external force acts on the animal threatening pursuit apparatus 100 via the tension string 38, and thus the animal threatening pursuit apparatus 100 can be prevented from being greatly damaged. .

The amount of water in the tension weight 39 suspended from the tension string 38 suspended from the pulley 37 is adjusted to adjust the tension of the tension string 38. In an equilibrium state, the swinging body 34 is swung so that the opening / closing essential part d1 closes the lower end opening of the cylindrical body 42a, and the tension string 38 is sandwiched by the clip 34a while maintaining this state. As a result, the swinging body 34 is kept biased by the weight of the pulling weight 39 toward the side where the lower end opening of the storage portion 42 is closed, and the opening / closing essential part d1 is positioned in a state where the lower end opening of the storage portion 42 is closed. Retained.

Next, the lid body 42b of the storage section 42 is removed from the cylinder body 42a, and the falling body 43 is inserted from the upper end opening of the cylinder body 42a. The inserted fall body 43 falls in the cylindrical body 42a, and its lower surface is supported by the opening / closing main part d1. After this insertion, the lid 42b is returned to its original position, and the upper end opening of the cylinder 42a is closed.

In this state, when the harmful animal hits the wire member 47, the tension string 38 is pulled forward, and the swinging body 34 is swung to the side that opens the lower end opening of the cylindrical body 42a. By this swinging, the opening / closing essential part d1 moves rearward and opens the lower end opening of the cylindrical body 42a. At this time, the falling body 43 in the cylindrical body 42a falls by its own weight, and when the falling body 43 collides with the bottom surface of the metal container 41, a large metal hitting sound is emitted, and at the same time, the metal container 41 is directed downward. The impact force acts to push and shift the push input portion 21 of the locking mechanism portion 18 downward. As a result, the plurality of bar members 3 are changed from the state shown in FIG. 5A to the expanded state shown in FIG. 5B. Since the bar member 3 expands with a loud sound as if the bar member suddenly unfolded the umbrella, an animal such as a spider can be struck by the illusion that something larger than itself suddenly appeared, and can drive away this. . At this time, each bar member 3 emits a wind noise and simultaneously vibrates the bell 5 by elastic vibration.
When the bar member 3 is in the unfolded state, the cover body 27 is struck by the moving body 30 and emits a striking striking sound and shoots forward, and the firecracker 28 is ignited and emits a violent explosive sound.

In the above embodiment, the explosive portion 102 is disposed at the front end portion of the guide track 1, but it may be loaded into the falling body 43 instead. FIG. 6 shows such an embodiment, and the storage section 42 of the previous embodiment is changed to a storage section 51 that stores the explosive section 104. Members having the same functions as those in FIG. 1 are denoted by the same reference numerals. The oscillating body 34 includes a horizontal plate 34 c and a metal bar 34 b extending upward, and the horizontal plate 34 c can be oscillated back and forth via a lateral shaft 35. The upper end portion of the metal bar 34b functions as an opening / closing main part d1. Pulleys 37a and 37b are rotatably mounted on both sides of the horizontal plate 34c.
The pulley 37b has a tip connected to an object to which an external force is applied, and a tension string 38 is wound around. Return. The tension string 38 is fixed to the horizontal plate 34c around the pulley 37a. The tension weight 39 is a water container having a lid that can be opened and closed. The tension string 38 is swung around the lateral axis 35 of the swinging body 34 in accordance with the front-rear displacement of the tension string 38.

The storage unit 51 is disposed directly above the metal container 41 with the upper surface opened. In FIG. 7, the storage portion 51 has a cylindrical shape and is fixed to the attachment portion 22. A lid 52 is provided to cover the upper end opening of the storage unit 51. The explosive sound part 104 has a bottomed cylindrical drop body 53 and a cover part 59. One end of the firecracker holding string 58 is fixed to the bottom surface of the falling body 53, and an annular portion 57 that is externally fitted to the outer peripheral surface of the firecracker 28 is formed at the tip. The ignition means 55 is fixed to the lid portion 59. The lid body 52 and the lid portion 59 are connected by a connecting string 54.

When storing the firecracker 56 in the storage section 51, the fallen body 53 is removed from the storage section 51, the firecracker 56 is inserted into the annular portion 57 of the firecracker holding string 58, and the tip of the ignition string 56a is ignited by the ignition means 55. And cover the cover 59. In a state where the opening / closing essential part d1 is directly under the storage part 51, the falling body 53 into which a firecracker is inserted is inserted into the storage part 51 from above, and the lid body 52 is put on.
On the other hand, when the harmful animal hits the wire member 47 and the tension string 38 is pulled to the front side, the opening / closing essential part d1 rotates and the explosive sound part 104 falls from the storage part 51 to the metal container 41. When the connecting string 54 is fully extended in a state where the speed has increased due to the free fall of the explosive sound part 104, the lid 59 is removed from the fallen body 53, and the ignition string 56a is pulled out by the ignition means 55 integrated with the lid 59. Firecracker 56 is ignited.

When the falling body 53 collides with the bottom surface of the metal container 41, a large metal hitting sound is emitted, and simultaneously, a downward impact force acts on the metal container 41 to cause the pushing input portion 21 of the locking mechanism portion 18 to move. It is the same as in the previous embodiment in that the plurality of rod members 3 are expanded at a stroke by being pushed downward.

According to the present embodiment, the firecracker 56 that has ignited emits an explosive sound in the metal container 4, thereby amplifying the sound. Further, by using a repetitive firecracker as the firecracker 56, it is possible to continue to explode in the metal container 41 and continue to produce a sound of explosion. This is not a state in which the firecrackers are repeatedly fired in the embodiment described above, but can be made to sound over a wide range because of explosion at a high position.
