Description

  The present invention relates to a harmful animal threat.

  Harmful animals such as salmon, monkeys, bears, crows, etc., produce various crops ("cereals such as yam, rice, wheat", "vegetables such as tomatoes, pumpkins", "fruits such as mandarin oranges, strawberries, strawberries, cherries, peaches) The damage caused by eating and ruining such a large amount is great.

  In particular, in recent years, due to abnormal weather, harmful animals that inhabit mountain forests, etc., appear in the villages to secure food, eat these crops, and infrequently damage farmers. ing. In addition, people living in the village have encountered damage such as encountering beasts (roars, bears, etc.) appearing in the village in search of food and being attacked by these beasts.

  In consideration of such circumstances, (1) a hollow case in which a squib of the squib wire is formed and a plurality of firecrackers connected to the squib wire, each firecracker is automatically ignited and ruptured sequentially with a time difference. A harmful animal threatening tool (see Patent Document 1, hereinafter referred to as “Conventional Example 1”) is proposed in which an explosion sound is generated intermittently and threatens a harmful animal. Further, (2) a plosive sound generating device containing a plurality of crackers made of toy gunpowder and a sensor for detecting the invasion of harmful animals, etc. Example 2 ”) is proposed.

Japanese Patent Laid-Open No. 10-136866 JP 2000-217498 A

  However, the harmful animal threats according to these conventional examples have the following problems.

  That is, in the harmful animal threat of conventional example 1, there is a possibility that the fire ignited by the lead wire may be extinguished spontaneously during the combustion, but after this natural fire extinguishing, it is no longer threatened by the harmful animal threat. The effect cannot be obtained. In addition, when a configuration in which a plurality of firecrackers are intermittently exploded as in Conventional Example 1 is adopted, another firecracker breaks due to the impact of the explosion of a predetermined firecracker, or a fire when a predetermined firecracker blows up There is a possibility that other firecrackers may ignite and cause other unscheduled blasting of the other firecrackers. Furthermore, in Conventional Example 1, moisture may adhere to the firecracker or become wet, and there is a possibility that the firecracker cannot be blown up as desired during use.

  On the other hand, the harmful animal threatening device of Conventional Example 2 has a complicated configuration that requires a control device and the like for controlling the operation of the sensor and the explosion sound generating device, and thus has a problem that the manufacturing cost increases. Moreover, since many electric parts are required, it cannot necessarily be said that it is appropriate as a harmful animal threatening instrument placed outdoors (farm cultivation place). This is because there is a possibility that various problems such as electric leakage and malfunction will occur in the electrical parts.

  Moreover, the harmful animal threatening device of Conventional Example 2 requires a power source for supplying electricity to the sensor, the control device, and the like, and thus has a problem that the installation location is limited. Furthermore, since the harmful animal threatening tool of Conventional Example 2 includes an electrically and mechanically movable part, there is a possibility that a malfunction such as a failure may occur.

  As described above, the conventional harmful animal threatening tools have problems such as not being able to expect a certain threatening effect but also increasing the manufacturing cost and limiting the installation location.

  An object of the present invention is to solve the above-mentioned problems, and to provide a harmful animal threatening tool that can reliably threaten harmful animals, can be manufactured at low cost, and can be installed at various installation locations.

The harmful animal threatening tool of claim 1 (hereinafter referred to as “weighing tool”)
A pair of support portions are provided above the predetermined installation surface with an interval, and at least one of the pair of support portions is a movable support portion,
A linear detection member supported by the pair of support portions and in a tensioned state;
A gunpowder body holding part that is provided at a predetermined position and holds the gunpowder body;

  In the first embodiment, a threatening system A configured by arranging a plurality of threatening tools S around the installation portion H as shown in FIG. 1 will be described. Here, the installation part H which is the installation target of the threatening system A is a cultivated land (agricultural land such as a field or a paddy field) having a substantially rectangular planar shape. In addition, the planar shape of the installation part H is not limited to a substantially rectangular shape, and may be, for example, a polygon or a trapezoid. Moreover, the installation part H is not limited to a flat ground, but may be an inclined land, a fan-shaped land, or the like.

  Next, the configuration of the threatening system A will be described. As shown in FIG. 1, this threat system A is configured by arranging three threat tools S along each side of the installation portion H.

  As shown in FIG. 2, substantially columnar (substantially square columnar) column members 30 (30A, 30B, 30C, 30D) are installed at the four corners of the installation portion H configured in a substantially rectangular plane. Moreover, the installation part H has four side edges L1-L4, and the support | pillar member 30 (30A, 30B, 30C, 30D) has two side surfaces (A1, A2, B1, B2, C1, C2, D1, D2) are substantially orthogonal to one side edge L1 to L4. In addition, in this specification, when each of the four support | pillar members 30 is distinguished and shown, it describes with "30A", "30B", "30C", and "30D". That is, the alphabetic characters “A” to “D” are added to the reference numeral “30” to indicate each of the four support members 30 separately.

  As shown in FIGS. 2 and 3, one side surface (for example, A2) of each support member 30 (for example, 30A) is adjacent along one side edge (for example, L1) of the installation portion H. The other side surface (for example, A1) of the column member 30 (for example, 30A) is opposed to one side surface B2 of the column member 30 (for example, 30B), and the other side edge (for example, L3) of the installation portion H. ) Is opposed to one side surface D1 of another supporting column member 30 (for example, 30D) adjacent to it.

  The holding member 40 is a member that supports (holds) a movable support member 50 described later. As shown in FIGS. 4 and 5, a holding hole 41 for inserting and holding the movable support member 50 is provided in the vertical direction. We prepare for three places along. And the axial center of these holding | maintenance holes 41 is comprised so that it may be on the same straight line with the explosive body 37 (substantially center part of explosive body holding | maintenance part 36D) hold | maintained at the explosive body holding | maintenance part 36D.

  The movable support member 50 is a member that constitutes a movable support portion. As shown in FIG. 5, the housing 51, a movable member 52 that is held in a movable state within the housing 51, a spring member 53, and a connecting member 54. Among these, the housing 51 is formed in a substantially cylindrical shape, and is arranged with its axis oriented in a substantially horizontal direction, and includes openings 51r and 51p at one end and the other end along the axis. The inner diameter of the opening 51r at one end of the housing 51 is smaller than the inner diameter of the opening 51p at the other end of the housing 51.

  One end portion of the housing 51 has an outer diameter that is increased in a stepped shape to form a flange portion 51a. Further, since the inner diameter of the housing 51 is reduced in a stepped manner on one end side of the housing 51, the housing 51 is constituted by a reduced diameter part 51g having a small inner diameter and a housing body 51h composed of other parts. ing.

  In the housing 51, a substantially ring-shaped contact surface 51c is provided at a boundary position between the reduced diameter portion 51g and the housing main body 51h, and a shaft of a central hole 51s provided at the center of the contact surface 51c. The center position coincides with the axial center position of the housing 51. Further, the internal space (substantially cylindrical internal space) of the housing main body 51h is opened by a center hole 51s and an opening 51r. The center hole 51 s, the opening 51 r at one end of the housing 51, and the opening 51 p at the other end of the housing 51 are in a state in which the center is aligned on the same straight line along the axis of the housing 51. ing.

  The housing 51 is supported by the holding member 40 by inserting and fixing the housing main body 51h into the holding hole 41 while directing the axis thereof in a substantially horizontal direction. When the housing 51 is fixed in this way, the center of the recess 36 (powder body holding part 36D), the center of the center hole 51s, the center of the opening 51r at one end of the housing 51, and the housing The central portion of the opening 51 p at the other end of 51 is aligned on the same straight line along the axial direction of the housing 51.

Further, the striking portion 52b has an end surface with a large area (hereinafter referred to as “protruding end surface”) 52d disposed at a position away from the second end surface 52v, and an end surface with a small area is integrated with the second end surface 52v at the center. It is in a state. Further, the axis of the member main body 52a and the axis of the striking portion 52b are located on the same straight line. Further, the outer diameter of the striking part 52b is gradually changed along the axial direction, but the outer diameter of any part of the striking part 52b is made smaller than the outer diameter of the member main body 52a.

  The moving member 52 is disposed in the housing 51 in a state where the first end surface 52c is opposed to the abutted surface 51c and the protruding end surface 52d is opposed to the recess 36 (powder body holding portion 36D). Further, since the outer diameter of the member main body 52a is slightly smaller than the inner diameter of the housing main body 51h and is much larger than the inner diameter of the reduced diameter portion 51g, the moving member 52 is located inside the housing main body 51h. It can be moved along the axial direction of 51h. The outer diameter of the housing body 51h is smaller than the inner diameter of the opening 51p at the other end of the housing 51.

  The spring member 53 constitutes a specific example of the urging means, and is constituted by a coil spring. In addition, the spring member 53 is interposed between the first end surface 52c of the member main body 52a and the abutted surface 51c in a compressed state, so that the moving member 52 has a recess 36 (powder body holding portion 36D). ) The urging force toward the direction is loaded.

  As shown in FIGS. 5 and 6, the connecting member 54 includes a linear member 54a, an engaged member 54b, and an engaging member 54c. Among these, the linear member 54a is composed of a piano wire, and the engaged member 54b is integrated at one end thereof, and the other end is integrated at the center position of the first end surface 52c of the member main body 52a. One end side of the linear member 54 a protrudes outside the housing 51 through the center hole 51 s and the opening 51 r at one end of the housing 51. Moreover, the end of the detection member 90 comprised using a piano wire is mounted | worn with the engaging member 54c.

  As shown in FIG. 6, the engaging member 54 c is a ring-shaped member, and the end of the detection member 90 is attached to one end and the attachment hole 54 f is provided to the other end. Further, the engaged member 54b is configured by a rod-like body (split pin) whose one end portion is divided into two. That is, the engaged member 54b is formed of a rod-like body, and a cut portion (interrupt portion) 54m along the axial direction is provided on one end side. The other end of the engaged member 54b is integrated with one end of the linear member 54a. Furthermore, the engaged member 54b can be inserted in a sliding state (or a state in which a slight gap is maintained) with respect to the mounting hole 54f of the engaging member 54c.

  The engagement of the engaging member 54c and the engaged member 54b is performed as follows. That is, as shown in FIG. 6, the engaged member 54b is inserted into the mounting hole 54f with one end thereof at the top, and one end of the engaged member 54b is inserted into the inside 541a (ring-shaped) of the engaging member 54c. Projecting inside the engaging member 54c. And if the one end part side of the to-be-engaged member 54b is extended in a "C" shape by using the notch part (interruption part) 54m as a boundary, the shape of the to-be-engaged member 54b will become Y shape. That is, plastic deformation (caulking) occurs on one end portion side of the engaged member 54b, and the one end portion constitutes the branch portions 55p and 55q that branch into a substantially V shape with the notch portion (interruption portion) 54m interposed therebetween. It will be.

  For this reason, the width of the portion of the engaged member 54b located in the interior 541a of the engaging member 54c (one end side of the engaged member 54b) is larger than the width of the mounting hole 54f. For this reason, the engaging member 54c and the engaged member 54b are engaged. That is, in order to remove one end of the engaged member 54b from the mounting hole 54f, a predetermined external force is applied to the detection member 90, and the branching portion 55p from the surface that forms the mounting hole 54f in the engaging member 54c. It is necessary to apply a certain external force to 55q and to make the width of the branch portions 55p and 55q smaller than the mounting hole 54f.

  As shown in FIGS. 1 and 3, in the threatening system A of the first embodiment, three threatening tools S are installed on each side edge L1 to L4 of the installation portion H. That is, in any of the side edges L1 to L4, three threats are formed from the upper side to the lower side between the column members 30 (30A, 30B, 30C, 30D) facing each other along the corresponding side edges L1 to L4. Tools S (an upper layer threatening tool S, a middle layer threatening tool S, a lower layer threatening tool S) are installed. For this reason, 12 threatening tools S are provided in the entire threatening system A. In addition, as shown in FIG. 1 and FIG. 3, between the upper end parts of the support | pillar member 30 (30A, 30B, 30C, 30D) which adjoins along each side edge L1-L4, long plate-like form stability A member 95 is suspended. Since the upper end portion of the holding member 40 is also fixed to the shape stabilizing member 95, the shape stabilizing member 95 stabilizes the upright state of the column member 30 (30A, 30B, 30C, 30D) and the holding member 40. It is planned. However, the shape stabilizing member 95 may be excluded from the intimidating system A.

  In any threatening tool S, the support portions at both ends thereof are constituted by the movable support member 50, and the detection members 90 are arranged along the corresponding side edges L1 to L4. In other words, the holding members 40 are installed in the vicinity of the strut members 30 facing each other along the side edges L1 to L4, and three movable support members 50 are mounted on these holding members 40, respectively. However, the protruding end surface 52d of the movable support member 50 attached to one of the support members 30 faces the recess 36 (powder body holding part 36D) provided in the one support member 30 and is attached to the other support member 30. The projecting end surface 52d of the movable support member 50 is opposed to the recess 36 (explosive body holding portion 36D) provided in the other column member 30.

  Further, the engaged member 54 b connected to the movable support member 50 mounted on one of the support members 30 and the engaged member 54 b connected to the movable support member 50 mounted on the other support member 30. , Facing along the corresponding side edges L1 to L4. The engagement member 54c attached to one end of the detection member 90 is engaged with one of the engaged members 54b facing along the side edges L1 to L4, and the other end of the detection member 90 is engaged with the other. The threatening tool S is installed by engaging the engaging member 54c attached to the portion. In other words, in any of the upper layer threatening tool S, the middle layer threatening tool S, and the lower layer threatening tool S, the pair of movable support members 50 are arranged coaxially with their axes substantially horizontal. Therefore, the axis of the detection member 90 is also substantially horizontal, and the detection member 90 is in a stretched state (stretched state).

  In any threatening tool S, when the engaging members 54c located at both ends of the detection member 90 are engaged with the corresponding engaged members 54b, the interval between the engaged members 54b is reduced. It is necessary to pull each engaged member 54b in the direction of the other engaged member 54b. Thus, the biasing force applied from the corresponding spring member 53 to the moving member 52 constituting one movable support member 50 constituting each threatening tool S and the moving member 52 constituting the other movable support member 50. It moves so that a space | interval may be narrowed mutually while opposing. In other words, in the pair of movable support members 50 constituting each threatening tool S, the projecting end surface 52d is formed in the recess 36 (powder body holding portion 36D) while the urging force applied by the moving member 52 from the corresponding spring member 53 is opposed. ) To a position (separated position) to be separated (see FIG. 5). When the harmful animal is not in contact with the detection member 90 (in a stretched state), the tension state of the detection member 90 is maintained.

  On the other hand, when the harmful animal comes into contact with the detection member 90, a predetermined external force is applied to the detection member 90, and the engagement of the engagement member 54c and the engaged member 54b is released, the pair constituting the threatening tool S In the movable support member 50, the moving member 52 moves in the direction of the corresponding column member 30 by the biasing force of the corresponding spring member 53. For this reason, the moving member 52 (striking part 52 b) projects out of the housing 51 through the opening 51 p at the other end of the housing 51. At this time, the projecting end surface 52d of the striking portion 52b moves to a position (striking position) that comes into contact with the concave portion 36 (powder body holding portion 36D) (see FIG. 8). If the gunpowder body 37 is attached, it will collide with this gunpowder body 37, the gunpowder body 37 will explode, and an explosive sound and a gunpowder odor will drift around.

  In this embodiment, when the harmful animal comes into contact with the tension detection member 90 and an external force of a predetermined level or more is applied to the detection member 90, the connection between the moving member 52 and the detection member 90 is released. Thereby, the moving member 52 is moved to the striking position (position where the striking portion 52b strikes the explosive body 37) by the urging force of the spring member 53 (biasing means), and is held by the explosive body holding portion (recess 36). An explosive sound and an explosive odor are generated in order to strike the explosive body 37. Therefore, harmful animals that have invaded the surroundings of the place where the threatening tool S is installed (such as farming parts and isolats) are surprised by explosive sound and explosive smell and dissipate.

  In addition, since the explosive body 37 is ruptured in the present embodiment, an explosive odor drifts around the explosive body 37 after it explodes. And more effective menace can be performed using this explosive odor and the learning effect of harmful animals. In other words, some pests and other harmful animals have experienced encountering a hunter with a hunting gun and have experienced the smell of gunpowder released from this hunting gun. In such a case, harmful animals often remember the smell of this explosive and are afraid of this smell. For this reason, according to the present threatening tool, the explosive body 37 is ruptured to cause an explosive odor to drift around the place where the explosive body 37 is installed.

  Furthermore, the threatening tool S of the present embodiment does not include an electrical part or an electrically movable part, so that the manufacturing cost does not increase and a failure does not occur. Moreover, since an electrical component is not required, it can be suitably installed outdoors (farm cultivation place). Moreover, since a power supply is not required, it can be suitably installed in various installation locations.

  Next, Example 2 will be described with reference to FIG. In the threatening system C according to the second embodiment, the moving member 52 moves in the vertical direction, and the recess 36 (powder body holding portion 36D) is installed in a state of opening upward below the moving member 52. This is different from the threatening system A of the first embodiment.

  Also in the threatening system C of the second embodiment, support members 30 (30A, 30B, 30C, and 30D) are installed at the four corners of the installation portion H having a substantially rectangular planar shape, and the two side surfaces (A1, A2) of the support member 30 are provided. , B1, B2, C1, C2, D, D2) are substantially orthogonal to one side edge L1 to L4 (not shown). In addition, holding portions 61 and 62 for supporting the movable support member 50 protrude from the two side surfaces (A1, A2, B1, B2, C1, C2, D1, and D2).

  These holding portions 61 and 62 are configured in a substantially plate shape protruding from the side surfaces (A1, A2, B1, B2, C1, C2, D, and D2) and include holding holes 61a and 62a in the vertical direction. The axial centers of the holding holes 61a and 62a are configured to be able to align with the explosive body 37 held in the explosive body holding portion 36D in the vertical direction.

  In the second embodiment, the axis of the movable support member 50 is oriented in the vertical direction. That is, the housing main body 51h is fixed to the holding portions 61 and 62 in a state where the intermediate portion is inserted into the holding holes 61a and 62a. That is, the housing 51 is fixed to the holding portions 61 and 62 by bonding the outer peripheral surface of the housing main body 51 h and the portions forming the holding holes 61 a and 62 a in the holding portions 61 and 62.

  In the movable support member 50, the opening 51r at one end of the housing 51 is disposed at the upper end, and the opening 51p at the other end of the housing 51 is disposed at the lower end. And the insertion holes 51G and 51H are provided in the other end part side of the housing 51 toward the diameter direction. These insertion holes 51G and 51H penetrate the wall portion of the housing 51, and are provided on the same line along a predetermined diameter direction of the housing 51 and along the corresponding side edges L1 to L4. The other points of the movable support member 50 of the embodiment are the same as those of the movable support member 50 of the first embodiment.

  The connecting member 84 of the second embodiment includes an engaged member 84b and an engaging member 84c. Of these, the engaging member 84c has the same configuration as the engaging member 54c of the first embodiment, and the engaged member 84b is also bifurcated at one end side, like the engaged member 54b of the first embodiment. It is comprised by the rod-shaped body (split pin). That is, the engaged member 84b is formed of a rod-like body, and a cut portion (interrupt portion) 84m along the axial direction is provided on one end side, and is in a sliding state with respect to the mounting hole 84f of the engaging member 84c. It is possible to insert in a state (or a state where a slight gap is maintained). In addition, the detection member 90 is configured using a piano wire as in the first embodiment, and is installed along the side edges L1 to L4 of the installation portion H. However, in the second embodiment, one end of the detection member 90 is integrated with the other end portion of the engaged member 84b (the end portion where the notch portion 84m is not provided).

  In the second embodiment, the engaged member 84b is inserted into the insertion holes 51G and 51H on the lower end side of the movable support member 50, with one end thereof (the end provided with the cut portion 84m) at the head, Moreover, the insertion holes 51G that are far from the corresponding column member 30 and the insertion holes 51G that are close to each other are inserted in this order. Then, one end portion of the engaged member 84b (the end portion where the notch portion 84m is provided) protrudes toward the corresponding column member 30, and this one end portion is engaged with the engaging member 54c (implementation). In the same manner as in Example 1, the engaged member 84b is deformed into a Y shape) to prevent the engaged member 84b from coming off from the movable support member 50.

  Further, in the second embodiment, in order to insert the engaged member 84b into the movable support member 50 as described above, the moving member 52 moves upward while resisting the urging force loaded from the spring member 53. It will be necessary. That is, it is necessary to move the projecting end surface 52d to a position (separated position) that separates the projecting end surface 52d from the recess 36 (powder body holding part 36D) while resisting the urging force loaded from the corresponding spring member 53. Become. In this state, when the engaged member 84b is inserted into the movable support member 50, the projecting end face 52d abuts on the engaged member 84b positioned below the end surface 52d, so that the position of the moving member 52 is maintained at the separated position. When the harmful animal is not in contact with the detection member 90 (in a stretched state), the tension state of the detection member 90 is maintained.

  On the other hand, when the harmful animal comes into contact with the detection member 90, a predetermined external force is applied to the detection member 90, and the engagement of the engagement member 54c and the engagement member 54b is released, the engagement member 84b moves. The support member 50 is removed. Thereby, in the movable support member 50 which comprises the threatening tool C, the moving member 52 moves vertically downward by the biasing force of the corresponding spring member 53. For this reason, the moving member 52 (striking part 52b) protrudes out of the housing 51 through the opening 51pq at the other end of the housing 51. At this time, the projecting end face 52d of the striking portion 52b moves to a position (hitting position) that contacts the recess 36 (powder body holding portion 36D), so that the explosive body 37 is attached to the recess 36 (powder body holding portion 36D). If so, it collides with this explosive body 37, explosive explosive body 37 explodes, and explosive sound and explosive odor drift around.

  In the second embodiment, the same effect as in the first embodiment can be obtained.
