Description

The present invention relates to a capturing machine for capturing animals such as wild animals and escaped pets.

2. Description of the Related Art Capturing machines have been proposed for capturing wild animals, escaped pets, and other animals. In both cases, a trapping net is released and deployed to surround the target animal and make it immobile. Patent Documents 1 and 2 are shown as examples of such trapping machines.
The capture device (net-skipping type capture device 20) of Patent Document 1 stores a substantially spherical weight 2 attached around a capture net 1 in a tip hook 3a at the tip of a deployable arm 3, and deploys the deployable arm 3. Accordingly, the approximately spherical weight 2 is ejected forward to spread the catching net 1 and cover it over the object to be caught. In addition, in the capture machine (restriction net injection device) of Patent Document 2, by releasing the compressed coil spring 32, the four weights 12 are each flown radially from the launch port 23a using the spring force of the coil spring 32. The restraining net main body 11 pulled by the weight 12 is ejected from the storage part 22 and is configured to fly while being deployed in the air.

All of these conventional trapping machines are configured so that when a trapping net is released, the net is already expanded from the released position and heads towards the target to be caught. However, if the distance to the target is still quite large and the target is spread out, the net will not be able to deploy properly due to the influence of the wind or slight deviations in the launching time of the ejected weight, and If it was deployed too quickly, it would take time to reach the target due to air resistance, and there was a possibility that the target would escape.
Therefore, there has been a need for a trapping machine that can gradually deploy the net after it is ejected until it reaches the target, and release the net so that it can accurately and quickly reach the target.

As a first means for achieving the above-mentioned purpose, in a capturing machine that releases a capture net toward a capture target and captures the capture target with the deployed capture net, the net storage is opened toward the front. the capture net that can be accommodated in the net accommodating section; a plurality of elongated bodies that are arranged around the net accommodating section and whose longitudinal direction extends forward from the front end of the net accommodating section; A partially or fully elastic member whose base side is fixed to a part of the capture net, and whose tip side is fixed to a weight that is folded back at the front end side of the elongated body and arranged near the base of the elongated body. a flexible traction member comprising: a first holding means for holding the weight in a state in which the traction member is extended to apply a biasing force; and a release means for releasing the biasing force of the traction member.
In such a configuration, the pulling member can be pulled and the elastic member biased, then folded back at the front end of the elongated body and fixed to the weight disposed near the base of the elongated body, and released. By releasing the first holding means by the means, the biasing force of the elastic member is released and the weight is ejected forward along the elongated body (here, "forward" means the elongated body ). When using a capture device, the tip of the elongated body is positioned so that it points toward the sky, depending on conditions such as the distance to the capture target and the size of the capture net. The user may hold it by themselves, or it may be fixed in a predetermined orientation using a device such as a stepladder or stand (not shown).
After ejection, the weight flies out in the longitudinal direction of the elongated body and deploys the capture net forward via the traction member, making it possible to accurately release the weight and capture the fish. Increases directionality when sending a capture net to a target. In addition, even after ejecting, the trapping net does not deploy immediately and can be deployed near the target to be captured. In addition, since the net can be thrown without immediately deploying, the time required to reach the target is shortened.

The "elongated body" may have a pipe-like shape or a solid shape, and may have a circular or rectangular cross-sectional shape, for example. Also, the material may be metal or wood.
"A traction member partially or entirely composed of an elastic member" may be a case in which the traction member itself is an elastic member, or only a certain portion is an elastic member and is connected in series with an elastic member. For example, when there is a part that does not have elasticity, such as a nylon string. The "flexible traction member" is particularly preferably a long member that can be easily wound, such as a rope or string. The shape may be, for example, a band-shaped body. "Elasticity" is the property of being deformed by an external force and returning to its original state when the force is removed. Here, by pulling the traction member, the elastic member undergoes a large deformation, and a biasing force is generated to return the elastic member to its original state. This will be used to make the weight fly.

Further, as a second means, the plurality of elongated bodies are supported by a first rotation shaft so as to swing in and out of the net housing part, and the extending direction can be changed depending on the swing position. At the same time, a second holding means for holding the device at a certain swinging position within the swingable range is also provided.
This allows the elongated body to be fixed at a certain swinging position within the swinging range depending on conditions such as the size and weight of the capture net, the size of the target to be captured, and the distance to the target. can. The swinging position of the elongated body, or in other words, the opening angle of the elongated body relative to the center line assuming the center line of the trapping machine.By changing this angle, it is possible to create a more suitable trapping net according to the conditions. This is because the expansion process can be obtained. For example, if the net is heavy and you want to fly it far (to cover a distant target), it is preferable to narrow the opening angle of the elongated body as much as possible so that the net can fly easily without opening. On the other hand, if the capture net is light and you want to fly it close (to cover a nearby target), conversely, by widening the opening angle of the elongated body, the capture net will open relatively early.
Further, as a third means, the second holding means includes a contacting body having a portion that comes into contact with the inner surface of the elongated body, and when the position of the contacting body is displaced, the elongated body The structure is such that the amount of outward protrusion of the portion that abuts the inner surface changes.
Thereby, the swinging position of the elongated body can be easily changed by displacing the position of the abutting body. This specifies a more specific configuration of the second holding means. The second holding means may have a configuration other than that described in the third means.
Further, as a fourth means, the abutting body is rotatably supported by a second rotation axis, and by rotating around the second rotation axis, the contact body advances outward according to the phase. I configured it so that the amount changes.
Thereby, the swinging position of the elongated body can be easily changed simply by rotating the abutting body.
Further, as a fifth means, the abutting body is configured in a disk or cylindrical shape, and is rotatably supported on the second rotation shaft in the circumferential direction, and the second rotation shaft is rotatable in the circumferential direction. It is arranged at a position offset from the center of the disk or cylinder shape.
This specifies the specific configuration of the abutting body of the fourth means. With such a configuration, since the second rotation axis is located at a position offset from the center, when the contact body is rotated, the amount of outward movement of the contact body changes depending on the phase. becomes. The abutting body may have a shape other than a disk or a cylinder, for example, a half-moon shape having a gradually decreasing or increasing abutting surface on the outer periphery. As long as the outer periphery has a contact surface that gradually decreases or increases, the second rotation axis may be located at the center rather than at a position offset from the center.

Further, as a sixth means, the elongated body, the first rotating shaft, the abutting body, and the second rotating shaft are arranged on a frame installed on a base. .
This specifies the specific structure of the mechanism that supports the elongated body and the abutting body. By arranging the elongate body and the abutting body on the base via such a frame, the swinging operation of the elongate body is made more efficient.
Moreover, as a seventh means, the elastic member is made of rubber.
If it is made of rubber, it is easy to handle, lightweight, and safe. Other elastic members such as coil springs and dampers are not excluded.
Moreover, as an eighth means, the plurality of elongated bodies are arranged radially around the net accommodating part.
As a result, the plurality of elongated bodies are arranged around the net accommodating part in a well-balanced manner, so that the trapping net can easily spread out neatly.
Further, as a ninth means, the first holding means is constituted by a first engaging part formed on the weight and a second engaging part arranged on the outer surface of the base of the elongated body, The releasing means is a means for releasing the engagement relationship of the second engaging part with the first engaging part.
With such a releasing means, the first engaging part and the second engaging part can be easily engaged and disengaged. In the first holding means, for example, the first engaging portion may be constituted by a ring-shaped wire, and the second engaging portion may be a protruding member inserted into the ring of the first engaging portion. The weight is held in that position, with the protrusion being locked in contact with the inner surface of the ring portion and being biased. Then, by retracting the protruding member, the engagement between the first engaging part and the second engaging part is released, and the weight is ejected forward along the elongated body by the released biasing force.

According to the present invention, since the weight can be accurately thrown along the elongated body, the directivity when sending the trapping net toward the target is improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of a trapping machine that is an embodiment of the present invention will be described below based on the drawings.
As shown in FIGS. 1 and 2, the trapping device 1 includes a base plate 2, a net storage part 3 fixed to the front surface (lower surface in FIG. 1) of the base plate 2, and a net storage part 3 arranged at equal intervals surrounding the net storage part 3. The basic configuration includes four arranged rails 4.
The net storage section 3 is a plastic flower pot-shaped case with a bottom and a circular outer periphery. As shown in FIG. 1, a catching net 5 is stored in the net storing section 3 in a folded state. A holding lid 7 supported by a hemispherical protrusion 6 formed on the inner circumferential side is disposed within the net storage portion 3. The trapping net 5 housed in the net storage part 3 is held by the holding lid 7 so as not to fall out. Incidentally, when the trapping device 1 is used, the holding lid 5, which obstructs the ejection of the trapping net 5, is removed. The rail 4 is composed of an aluminum alloy pipe having a rectangular cross section.
The base plate 2 is a plastic plate having a perfect circular shape in plan view, and has a handle 8 erected at the center of the rear surface (upper surface in FIG. 1). The plastic handle 8 is a cylindrical member having an outer periphery with a circular cross section. A movable piece 9 is loosely fitted onto the outer periphery of the handle 8 so as to be slidable in the longitudinal direction of the handle 8. The operating piece 9 has a bobbin-shaped outer shape for winding a thread, and has ring-shaped flanges 9a formed at the top and bottom. A coil spring 10 is disposed around the handle 8 and between the base plate 2 and the operating piece 9 (lower flange 9a). The state shown in FIG. 1 in which the working piece 9 is placed on the coil spring 10 is the default state of the working piece 9. When the operating piece 9 is pushed to approach the base plate 2 side, the coil spring 10 is compressed and a biasing force is generated. When the pushing motion is released, the operating piece 9 is pushed back by the biasing force of the released coil spring 10 and returns to the default state.
As shown in FIGS. 1 and 2, four frame units 11 are arranged near the periphery of the rear surface of the base plate 2 at angles shifted by 90 degrees with respect to the center of the base plate 2. Each frame unit 11 is composed of two fixed plates 11a made of aluminum alloy bent into an L shape and arranged with an interval therebetween so as to be mirror-image symmetrical. The four frame units 11 are arranged radially from the center. The fixing plate 11a of each frame unit 11 is fixed to the base plate 2 by screws 12a and nuts 12b so that about 1/3 of the outer area protrudes (projects) from the base plate 2.

The rail 4 is held between opposing fixed plates 11a of the projecting portion of each frame unit 11 and supported by a first rotation shaft 15 inserted between the fixed plates 11a. As a result, the rail 4 is disposed outside the net storage section 3 and is able to swing toward and away from the net storage section 3. As shown in FIG. 1, the total length of the portion of the rail 4 on the front side of the first rotating shaft 15 is about four times the total length of the portion on the base side thereof. There is. Hereinafter, the portion on the base side of the first rotation shaft 15 will be referred to as the base side swinging section 4A, and the portion on the front side of the first rotation shaft 15 will be referred to as the injection side swinging section 4B. The ejection side swinging part 4B has a length a little more than three times the total height of the net storage part 3, and extends further forward than the front end (lower end in FIG. 1) of the net storage part 3.
A cap 16 is attached to the tip of the rail 4. The tip of the cap 16 has a rope engaging recess 16a cut out in a semicircular shape. The rope engaging recess 16a is located at a position where a pulling rope 34, which will be described later, is folded back. An adjustment plate 17 is fixed to the outer surface of the rail 4 near the rear end. The adjustment plate 17 is an auxiliary member that compensates for the insufficient thickness (thickness) in the width of the rail 4. A communication path 18 is formed which passes through the rail 4 and the adjusting plate 17 by crossing the rail 4 and the adjusting plate 17 from the inside to the outside.

An angle adjustment disk 21 is disposed at an inner position adjacent to the rail 4 in each frame unit 11. The angle adjustment disk 21 is disposed between the fixed plates 11a, and is rotatably supported by a second rotation shaft 22 parallel to the first rotation shaft 15. The angle adjustment disk 21 is a flat cylindrical plastic member, and the outer circumferential surface 21a of the angle adjustment disk 21 comes into contact with the inner surface of the rail 4 on the base-side swinging portion 4A side. The rail 4 is held at an arbitrary swinging position (opening angle) by the frictional force at the contact position. Since the second rotation shaft 22 is inserted not through the center of the circular shape of the angle adjustment disk 21 but at a position shifted from the center, the distance from the second rotation shaft 22 to the outer circumferential surface 21a is not equal. Therefore, when the angle adjustment disk 21 is rotated, the distance to the contact position of the rail 4 varies depending on the phase, and as a result, the swinging position of the rail 4 (in other words, the center line O passing through the center of the handle 8) It is possible to change the extending direction of the rail 4 in the longitudinal direction depending on the angle at which the rail 4 opens outward relative to the rail 4. For example, if the position p where the outer circumferential surface 21a of the angle adjustment disk 21 contacts the inner surface of the rail 4 is far from the second rotating shaft 22 as shown in FIG. Placed. On the other hand, if the rails 4 are close together as shown in FIG. 4(b), the angle of the rail 4 will be large, and the rail 4 will be inclined so that the tip side is relatively more open than in FIG. 4(a).

As shown in FIGS. 1 to 3, an injection device 23 as a releasing means is disposed between the lower flange 9a of the operating piece 9 and the base side swinging portion 4A of the rail 4. The injection device 23 consists of a main body 24 constituting a bar screw, a long nut 25 for a joint nut that is screwed onto the main body 24, and a double nut 26 that is placed before and after the long nut 25 and serves to prevent the long nut 25 from loosening. It is configured. The base end side of the main body 24 is connected to the lower flange 9a of the operating piece 9, and the distal end side is made to protrude outside the adjustment plate 17 through the communication path 18. The protruding portion of the main body 24 including its tip is defined as a locking peg 27. The long nut 25 is movable to any position in the longitudinal direction of the main body 24, and is fixed at that position by a double nut 26. This adjusts the amount of protrusion of the locking peg 27.
As shown in FIGS. 1 and 2, a net ejection mechanism 28 is disposed between the locking peg 27 and the capture net 5. The net ejection mechanism 28 is a combination of a weight 30, a rubber band 33 as a traction member disposed between the weight 30 and the capture net 5, and a woven cotton attracting rope 34 connected in series (hereinafter, this combination is referred to as a combination). (referred to as a traction set 35). The rubber band 33 is made of a material that is both elastic and flexible, and the attraction rope 34 is made of a material that is not elastic but only flexible.
A weight 30 is locked to the locking peg 27. As shown in FIGS. 5(a) and 5(b), the weight 30 is a block body made of a lead alloy and having a substantially rectangular parallelepiped shape. The base of a ring-shaped locking portion 31 made of wire is embedded in the upper surface of the weight 30. The base of a hanger 32 made of wire is embedded in the upper surface of the weight 30. The rubber band 33 side end of a tow set 35 is connected to the hanger 32, and the lure rope 34 side end is connected to the capture net 5.
When setting the net ejection mechanism 28, first, in the towing set 35, the attracting rope 34 is lowered approximately along the rail 4 from the capture net 5 stored in the net storage section 3, and the rope attached to the cap 16 at the tip of the rail 4 is lowered. Fold it back at the engagement recess 16a. The length of the rubber band 33 connected to the attracting rope 34 is such that it cannot reach the hanger 32 of the weight 30 that is locked (suspended) on the locking peg 27 unless it is pulled and stretched. Therefore, when the net injection mechanism 28 is set as shown in FIG. 1, the rubber band 33 is sufficiently stretched and urges the weight 30 forward (toward the tip of the rail 4).
In FIG. 1, in order to explain the rail 4 as a basic configuration, the net injection mechanism 28 is shown for only one rail 4 on the left side and the others are omitted, but in reality, in this embodiment, A net injection mechanism 28 is provided on all four rails 4.

Next, a method of using the trapping machine 1 configured as described above will be explained.
The user or the like determines the swinging position (that is, the angle) of the rail 4 by rotating the angle adjustment disc 21 so as to obtain the optimal ejection direction according to the capture net 5 to be used and the distance to the capture target. . At this time, if the rail 4 swings significantly as shown in FIG. 4(b), the locking peg 27 may protrude too much. In that case, by moving the position of the long nut 25 of the injection device 23 further outward, the amount of protrusion of the locking peg 27 can be reduced. Here, it is assumed that the net injection mechanism 28 is fixed at the swinging position of the rail 4 shown in FIG. The four rails 4 are arranged so as to surround the net storage part 3 with the front side slightly open outward.
The user or the like holds the trap 1 in this state by himself or prepares a stepladder or a stand and sets the net storage part 3 toward the sky (the state shown in FIG. 6(a)). In the set state, the net storage section 3 is oriented laterally or upwardly rather than horizontally, so the trapping net 5 stored in the net storage section 3 does not fall out, so the holding lid 7 is removed at this stage. Then, the operating piece 9 is pushed in the direction of the base plate 2 while determining the direction so as to be ejected in the direction of the target to be captured. Then, as the operating piece 9 advances, a force is generated that pulls the main body 24 connected to the lower flange 9a backward, that is, toward the center of the capture device 1, and the tip of the protruding locking peg 27 is pulled into the adjustment plate 17. Move so that you are immersed in it. Then, the locking portion 31 of the weight 30 that was locked to the locking peg 27 is released, the urging force of the rubber band 33 is released, and the weight 30 is ejected forward along the rail 4 (toward the tip of the rail 4). Ru. The trapping net 5 jumps forward by the attracting rope 34 connected to the rubber band 33 and gradually unfolds to reach the target to be captured.

At this time, in order to allow the catching net 5 to unfold more neatly, at least one selected from among the adjustment of the opening angle of the four rails 4, the adjustment of the weight of the four weights 30, and the adjustment of the rubber band 33. It is good to make adjustments. This is because in order to capture the target, it is necessary to fly the upper rail 4x to the other side of the target. In other words, it is preferable that the upper side of the catching net 5 spread out slightly in advance.
More specifically, as shown in FIG. 7, it is assumed that two rails 4x are arranged above and two rails 4y are arranged below with respect to the horizontal ground line G. In this case,
a) Control the opening degree (opening angle) of the upper rail 4x to be smaller than the opening degree of the lower rail 4y so that it reaches farther and faster.b) Control the weight 30 of the upper rail 4x. c) Make it heavier than the weight 30 of the lower rail 4y c) Make the biasing force of the rubber band 33 of the upper rail 4x stronger than the biasing force of the rubber band 33 of the lower rail 4y, etc. for more precision. The capture net 5 can be efficiently surrounded by the target to be captured.

With this configuration, the trapping machine 1 of this embodiment provides the following effects.
(1) Since the weight 30 is ejected along the rail 4 and the capture net 5 housed in the storage section 3 is released and deployed forward, the direction in which the capture net 5 is directed can be determined accurately. .
(2) Since the weight 30 pops out along the rail 4 in the direction of the extension of the rail 4, the pulled catching net 5 does not immediately spread out around it, but instead maintains a folded state with low air resistance. The time required for the net 5 to reach the target is shortened, and the net 5 can be thrown far because there is little air resistance.
(3) The swinging position (that is, the angle) of the rail 4 can be changed by the user as appropriate depending on the situation by rotating the angle adjustment disc 21. Further, the swinging position of the rail 4 can be easily changed by simply rotating the angle adjustment disc 21.

The above embodiments are merely described as specific embodiments for illustrating the principles and concepts of the present invention. That is, the present invention is not limited to the above embodiments. The present invention can also be embodied in the following modified forms, for example.
- The trapping machine 1 of the above embodiment is an example, and other embodiments may be implemented. For example, although the rail 4 is configured with four rails in the above example, it may be configured with other than four rails. Further, for example, the adjustment plate 17 may not be used, or a weight 30 of another shape may be used. The releasing means for releasing the biasing force of the weight 30 may also be implemented with a configuration other than the above. Since the rail 4 only needs to be a long body, it does not have to have a rectangular cross section, and the material is not limited.
- In the above, the rubber band 33 is used to extend the traction member and apply a biasing force, but the biasing force may be applied by means other than the rubber band 33, such as a coil spring. 28
- Although the rubber band 33 and the pulling rope 34 are connected in series to form the traction set 35 as a traction member, the entire traction member may be composed of the rubber band 33.
- Since the weight 30 is ejected with the locking portion 31 side as the traveling direction, a protective member may be provided to protect the locking portion 31. For example, the weight 30 may be provided with an arch-shaped metal protective cover 41 as shown in FIG.
・The presser lid 7 may be omitted.
- You may make it provide the structure which changes the rocking position of the rail 4 other than the angle adjustment disc 21 of the capture machine 1 of the said embodiment. For example, although the angle adjustment disk 21 is configured as a disk having a circular outer periphery in the above example, it may be configured so that the curve of the outer periphery gradually decreases or increases.
The present invention is not limited to the configuration described in the embodiments described above. The components of each of the embodiments and modifications described above may be arbitrarily selected and combined. Also, any component of each embodiment or modification, any component described in the means for solving the invention, or a component that embodies any component described in the means for solving the invention.
