Description

  The present invention relates to, for example, a trap or other animal capturing apparatus.

Wild animals such as sea breams and bears have moved into the vicinity of the village in search of food, and have devastated fields and crops, sometimes causing harm to livestock and humans. Yes. On the other hand, in order to prevent the damage of wild animals such as sharks, residents are taking various measures such as installing protective fences and nets, or trapping them with traps. However, protective fences, nets, etc. do not have a sufficient effect and do not stop the increase in the number of spears, etc., and often have catch traps. As a conventional capture device, for example, as shown in Patent Document 1, a bag body provided with a gate opening on one side, a closing lid that moves the gate up and down to open and close the opening, and a suspension lid It has a wire, a lock device that locks the free end of the wire, and a sensor that detects that the bag has entered the bag body. When the sensor detects that a bag has entered the bag body, the sensor opens the free end of the wire, and the closing lid falls to close the gate opening.

  However, in the capture device described in Patent Document 1, since the entrance of the cocoon body is relatively narrow, when the eagle is wary and does not enter the eagle, or when one eagle is in the eagle, Since no frogs can enter inside, they can only catch one animal at a time, so there is a problem that the catching efficiency is very low and it cannot catch up with the expanding damage. In addition, it is conceivable to enlarge the main body of the bag in order to secure the entrance and the accommodation space. However, this increases the weight, increases the cost, and increases the labor required for assembly and transportation. There was a problem of low practicality.

  The present invention has been made in view of the above-described conventional problems, and one object of the present invention is to provide an animal capturing apparatus that can efficiently capture animals while utilizing the behavioral characteristics of animals such as pupae. . Still another object is to provide a beast capturing apparatus that has a simple structure, can be manufactured at low cost, and can be reduced in size and weight.

  In order to solve the above-mentioned problem, the present invention includes a cage main body 12 that forms a space S in which a beast enters and surrounds the outer periphery in a polygonal shape in plan view by the top wall portion 12a and the peripheral wall portions 12b and 12c. A plurality of doors 14 provided to freely open and close each of a plurality of adjacent adjacent surfaces (12c), a sensing unit 16 for sensing whether or not a beast W has entered the space S of the cage body 12, And a simultaneous closing mechanism 18 that simultaneously closes the doors 14 of the plurality of adjacent surfaces when the detecting unit 16 detects the beast W. In addition, for example, by forming a plurality of adjacent closed wall portions in the peripheral wall portion other than the door portion, it is possible to ensure high strength of the bag main body without complicating the configuration.

  The simultaneous closing mechanism 18 may include a self-weight closing door portion 14 and an open holding mechanism 22 that holds all the door portions 14 that are simultaneously closed in a releasable open state.

  Further, the open holding mechanism 22 is mechanically linked to all the door portions 14 that are simultaneously closed, and in response to the detection of the presence of the beast W by the detection portion 16, all the door portions 14 are operated in one closing direction. It is good also as having the mechanical linkage apparatus 24 which closes simultaneously.

  In addition, the mechanical linkage device 24 includes a plurality of locking bodies 26 that lock the open state of the door portion 14 while changing the position according to the open state and the closed state of each door portion 14, and all the engagement members. One mechanical actuating body 28 that releases the latching state of all the latching bodies 26 by one actuating operation that is linked to the stationary body 26 and responds to sensing from the sensing unit 16 may be included.

  Further, each locking body 32 and the machine operating body 28 may be connected to each other by the rope 40.

  Further, the locking body 32 is attached to a shaft 30 attached to the main body 12 so as to be rotatable about the axis, and the position around the axis corresponds to the open state and the closed state of the door portion 14. A part of the lever member 32 may be rotatably supported and rotate integrally with the locking body 32.

  Further, the mechanical actuating body 28 may include a rotating member 38 that entrains the rope 40 and rotates in the rewinding direction.

  Further, the open holding mechanism 22 is engaged against the urging force of the urging device 42 and the urging device 42 that urges the mechanical operating body 28 so as to cause the locking member 32 to close the door portion 14. An interlocking device 44 that holds and holds the machine operating body 28 at a position where the stop body 32 holds the door portion 14 in an open state and operates the machine operating body 28 by the detection of the sensing unit 16 may be provided.

  Moreover, the door part 14 is good also as being provided so that the adjacent multiple surface (14c) may be opened and closed respectively so that a vertical sliding movement or the lower end part rocking | fluctuation is possible for the bag main body 12.

  In addition, the sensing unit 16 is supported in a freely swingable manner in the space S inside the cage main body, and is placed on the contact body 62 that swings in contact with the beast W and the contact body 62. In addition, a weight 64 that falls when the contact body 62 swings and operates the simultaneous closing mechanism 18 may be included.

  In addition, the sensing unit 16a is supported in a swingable manner while hanging downward in the cage main body space S, and is linked to the contact body 62 that swings in contact with the beast W, and the contact body 62, and a simultaneous closing mechanism. 18 may be included.

  The sensing unit 16b may include a step 74 that activates the simultaneous closing mechanism 18 when the beast W is placed.

  Further, the heel body 12 and the door portion 14 are configured to form a gap H that does not allow a human foot F to be sandwiched between the lower end side of the door portion 14 and the ground when the door portion 14 is closed. It may be done.

  Further, the bag body 12 may be provided with an escape opening / closing door 76 for the person M in the bag to escape when the door portion 14 is closed.

  According to the beast capturing apparatus of the present invention, the main body and the peripheral wall portion surround the outer periphery in a polygonal shape in plan view to form a space for the beast to enter, and a plurality of adjacent adjacent surfaces of the peripheral wall portion. A plurality of doors provided to freely open and close each, a sensing unit for detecting whether or not a beast has entered the space of the cage body, and each of adjacent surfaces when the sensing unit senses a beast And a simultaneous closing mechanism that simultaneously closes the door portion. As a result of simultaneously closing the door portions of the adjacent multiple surfaces, the adjacent multiple surface portions of the bag body are continuous in the open state of the door portion. An opening is formed in the body, and a relatively large entrance opening for a beast can be secured without enlarging the main body of the cage. Therefore, for example, since the beast can enter the main body without feeling alert, and more than one beast can enter at the same time, the beast can be captured efficiently. In addition, by closing all the doors simultaneously through the simultaneous closing mechanism, the animals once entered the main body of the cage and sensed by the sensing unit have no time to escape, making it difficult to escape. Can capture reliably.

  In addition, since the simultaneous closing mechanism includes a self-weight closing type door portion and an open holding mechanism that holds all the door portions that are simultaneously closed in a releasable open state, the door portion is closed by its own weight. For example, the driving force for closing the door portion itself is not required only by the opening operation, and the closing mechanism can be configured with a simple structure. Further, the door can be easily switched from the open state to the closed state. Moreover, since the door is closed smoothly and in a short time by its own weight, it is possible to reliably capture the beast.

  The open holding mechanism is mechanically linked to all doors that are simultaneously closed, and is a machine that simultaneously closes all the doors in one closing direction in response to detection of the presence of the beast by the sensor. By having the linkage device, the door is closed by only one operation after the sensing unit senses the animal, so there is little loss of time until the door is simultaneously closed, and the animal can be captured reliably. . Furthermore, the apparatus configuration can be simplified and can be manufactured at low cost. In addition, since it is configured by mechanical linkage, there are fewer failures than those of electrical linkage, maintenance is simple, and durability is high.

  In addition, the mechanical linkage device includes a plurality of locking bodies that lock the open state of the door portion while changing the position corresponding to the open state and the closed state of each door portion, and links to all the locking bodies. However, it is configured to include one mechanical actuating body that releases the locking state of all the locking bodies by one operation operation that responds to the detection from the sensing section, and thereby the door portion is moved by the locking body. Locks against its own weight, can hold the open state reliably, and can release the locked state simply by changing the position of the locking body via the machine operating body, and can implement a mechanical linkage device with a simple configuration . In addition, since the locking state of the plurality of locking bodies is released by only one operation of one mechanical operating body, the closing of the door portion can be reliably synchronized and simultaneously closed by its own weight. Can be captured.

  In addition, since each locking body and machine operating body are connected by a rope, the rope is flexible, so the positional relationship between the locking body and the machine operating body is not easily restricted and is designed easily. In addition, it is possible to implement a linkage structure that reliably transmits the operation of one mechanical operating body to a plurality of locking bodies with relatively inexpensive structural members.

  In addition, the locking body is attached to the shaft attached to the main body so as to be rotatable about the axis, the position around the axis corresponds to the open state and the closed state of the door portion, and a part of the rotation around the axis. By having a lever member that is freely supported and rotates integrally with the locking body, it is possible to arrange the locking body efficiently with a simple configuration, and furthermore, only a rotation operation around the axis of the locking body. Thus, the open and closed states of the door can be changed reliably and smoothly. Further, for example, by providing the lever member to a certain extent, the locking body can be reliably operated even if the operating force from the mechanical operating body is small. As a result, the mechanical linkage apparatus including the machine operating body can be realized with a simple structure.

  Further, the mechanical operating body is composed of a rotating member that entrains the rope and rotates in the rewinding direction, so that, for example, in one operating operation such as a rotating operation, the locking state of all the locking bodies is achieved via the rope. Thus, the mechanical operating body can be specifically realized with a simple configuration and at a low cost.

  Further, the open holding mechanism includes a biasing device that biases the mechanical operating body so that the door is closed by the locking body, and the locking body resists the biasing force of the biasing device. The interlocking device that holds and holds the machine operating body in a position where the mechanical operating body is held in an open state and activates the machine operating body by sensing of the sensing unit, so that the locking body is reliably and smoothly positioned via the biasing device. The door can be reliably closed by changing the position. Further, by using, for example, an elastic member such as a spring or rubber as the biasing device, the configuration is simple using a simple driving source, and the device can be manufactured at low cost. Furthermore, it is possible to change the holding of the door portion by the locking body via the interlocking device and the simultaneous closing operation of the door portion after sensing by the sensing portion smoothly and surely to capture the beast. it can.

  Further, the door portion is provided on the bag body so as to be vertically slidable or swingable at the lower end portion so as to open and close adjacent surfaces, whereby a self-closing door portion can be realized with a simple configuration.

  In addition, the sensing unit is supported in a swingable manner while hanging down the lower side in the inner space of the cocoon body, and is placed on the contact body that swings in contact with the beast and the contact body. A structure that includes a weight that falls when it moves and activates the simultaneous closing mechanism, so that it can be manufactured at a low cost with a simple structure, and can be detected reliably, and the animals that have entered the body of the cage Can be captured reliably. Furthermore, the durability and weather resistance are good, the sensor can be used repeatedly for a long time, and a highly practical sensing unit can be realized.

  In addition, the sensing unit is supported in a swingable manner while hanging down the lower side in the inner space of the cocoon body, a contact body that swings in contact with the beast, a solenoid that is linked to the contact body and operates a simultaneous closing mechanism, , The beast can be reliably detected, and the beast that has entered the main body of the cage can be reliably captured.

  In addition, the sensing unit includes a step that activates the simultaneous closing mechanism when a beast is placed, so that the sensing unit can be formed at a low cost with a simple structure. Moreover, durability and weather resistance are high, and it can be used repeatedly for a long period of time.

  Further, the bag body and the door portion are configured to form a gap that does not allow human feet to be sandwiched between the lower end side of the door portion and the ground when the door portion is closed, for example, When the door part is configured to slide up and down, when the door part is accidentally slid and dropped when the door part is lifted up and opened, the operator's feet are caught in the door part. Injury can be prevented. In addition, safety can be secured with a simple structure.

  In addition, since the door body is provided with an escape opening and closing door for the person in the bag to escape when the door is closed, for example, when a human child or the like is accidentally trapped in the bag, Even when the door is made of a heavy material, it can be easily escaped through the escape door. Therefore, safety for humans can be taken into consideration, and it can be installed well near the house where children and the like live.

  The beast capturing apparatus of the present invention will be described below with reference to the accompanying drawings. The beast capturing apparatus of the present invention is, for example, a trap-type capturing apparatus, and is installed in a forest near the house or in the back of a mountain, and is used to capture beasts such as cormorants that damage fields and the like.

  1 to 10 show an embodiment of the animal capturing apparatus of the present invention. In the present embodiment, the animal capturing apparatus 10 includes a cage main body 12, a plurality of door parts 14, a sensing part 16, and a simultaneous closing mechanism 18.

  As shown in FIGS. 1, 2, and 3, in this embodiment, the cage main body 12 includes a top wall portion 12 a, four peripheral wall portions 12 b, 12 b, 12 c, 12 c, and a bottom wall portion 12 d. It consists of a square or rectangular closed box in plan view in which the capture space S is formed. Each of the wall portions 12a to 12d is configured by, for example, forming a metal bowl-shaped member such as an angle member or a reinforcing bar into a rectangular frame shape and further assembling the inside of the frame in a lattice shape. In this embodiment, as shown in FIG. 3 and FIG. 4, when the lower side is a front side in a plan view, among the four peripheral wall portions 12 b, 12 b, 12 c, and 12 c, continuous corresponding to the front side and the right side. The adjacent two surfaces 12c and 12c form a door portion 14 (two-dotted line in FIG. 3) for freely opening and closing the bag main body 12. On the other hand, the adjacent two surfaces 12b and 12b which are the other back side and left side facing the door part 14 in the peripheral wall part are normally closed wall parts. In the opened state of the door portion 14, two continuous adjacent surfaces 12 c are formed in the cage main body 12, and an entrance opening for a beast having a relatively large area can be secured in the cage main body 12. Furthermore, an adjacent closed wall portion in which half of the peripheral wall portions are continuous is formed, and the strength of the heel body can be ensured without complicating the configuration. Moreover, as shown in FIG. 3, if the feed K is arranged at the corner of the peripheral wall portion 12b serving as a closed wall portion, a sufficient distance from the door portion 14 to the feed K can be secured, and the bag body is enlarged. Therefore, the substantial capture space S can be secured relatively widely. Note that the bag body 12 can be easily transported by, for example, being configured to be assembled and disassembled. Further, the heel body 12 is not limited to a quadrangular shape in plan view, but may be any polygon. For example, in the case of a polygon in a plan view (four or more squares), the number of doors may be an integer number of two or more adjacent surfaces and half or less of the polygonal surface, and may be provided in an arbitrary number of consecutive adjacent surfaces. .

  As shown in FIGS. 1 and 2, the door portion 14 is a door that freely opens and closes the capture space S of the basket body 12, and becomes a part 12 c of the peripheral wall section that closes the capture space S of the basket body 12 when closed. In the open state, an opening that communicates the inside and outside of the bag body is formed. Each door portion 14 is configured as a rectangular body in which reinforcing bars and the like are assembled in a lattice shape as described above, and the edge frame portions on both the left and right sides are vertically slid and moved to the vertically long guide rails 20 provided on the main body 12. Guided freely. That is, the door part 14 moves up and down using a vertical plane including the side surface of the bag main body as a movement plane. As shown in FIG. 6, the guide rail 20 is made of, for example, U-shaped steel or the like, and stands in a state where the U-shaped opening side is opposed in parallel to the left and right sides of each door portion 14.檻 The body is fixed integrally with the bolt / nut or welding. And the door part 14 is loosely fitted by the edge frame part side of both right and left in the U-shaped opening space | gap of the guide rail 20, and a vertical movement is smoothly guided. For example, the door portion 14 is lifted upward by a manual lifting operation to be in an open state, and is lowered from its open state by its own weight to close the opening. It has become. The door portion 14 is held in an open state by an open holding mechanism described later. In addition, since each door part 14 has weight, it is the structure which can be slid up and down independently, respectively, For example, you may connect adjacent door parts integrally.

  As shown in FIGS. 1, 6, and 8, leg portions 14 b extending downward from the lower edge frame are formed on the lower side of the edge frame portion of the door portion 14. When the door portion 14 is closed, the leg portion 14b forms a gap H between the lower edge of the door portion 14 and the ground side by the length of the leg portion 14b. The length of the leg portion 14b is set to a size that is higher than the height of the upper foot of a general adult foot F of about 10 to 20 cm, for example, and does not allow animals to pass through. That is, the door portion 14 and the heel body 12 are configured to form a gap that does not pinch the foot when the door portion 14 is closed. Thereby, for example, when installing the capture device, even if the door portion 14 is unexpectedly dropped when the door portion 14 is lifted, it is possible to prevent the operator's foot F from being injured, and in terms of safety. Considerable configuration can be realized. In addition, a stopper or the like for receiving the door portion is provided at an intermediate position on the guide rail 20 side lower side of the main body 12 so that the gap H is received by the stopper at the intermediate position when the dead weight of the door portion 14 is closed. May be.

  The simultaneous closing mechanism 18 is a simultaneous closing means that simultaneously closes the doors 14 on the plurality of adjacent surfaces when the sensing unit 16 senses a beast W such as a cage that has entered the body of the cage. By closing the plurality of door portions 14 at the same time, the beasts that have entered the cage body 12 are reliably captured. In this embodiment, as shown in FIGS. 1 and 4, the simultaneous closing mechanism 16 is an opening that holds the above-mentioned self-closing door portion 14 and all the door portions 14 that are simultaneously closed in an open state so as to be releasable. Holding mechanism 22.

  The open holding mechanism 22 holds the door portion 14 closed by its own weight in an open state against gravity, and simultaneously releases the holding state of all the door portions 14 to cause the door portion 14 to drop by its own weight and close it. These are means for holding and simultaneously releasing the open state of the door portion 14. In the present embodiment, as shown in FIGS. 4 and 5, the open holding mechanism 22 includes a mechanical linkage device 24 that is mechanically linked to all the door portions 14 that are simultaneously closed. In this embodiment, since it is mechanical linkage, a battery, battery, or circuit waterproof configuration or the like is not required as compared with an electrical linkage mode, and it can be easily configured, and maintenance and management can be easily performed.

  In the present embodiment, the mechanical linkage device 24 is configured to simultaneously close all the door portions 14 linked in one closing direction in response to the sensing of the presence of the beast by the sensing portion 16. Therefore, there is little time difference between the sensing unit 16 sensing the animal and the door 14 being closed, and the animal can be reliably captured. Specifically, the mechanical linkage device 24 is responsive to sensing from the sensing unit 16 while being linked to all the latching bodies 26 and a plurality of latching bodies 26 that latch the open states of the respective door portions 14. And one mechanical operating body 28 that releases the locked state of all the locking bodies 26 by one operation. Note that the mechanical linkage device is not limited to the configuration including the locking body 26 and the mechanical operating body 28. For example, the door 14 is suspended from above with a wire to hold the door open, The structure which can close simultaneously other arbitrary door parts, such as the structure which cancels | releases holding | maintenance of this wire in the case of, may be sufficient.

  As shown in FIGS. 1, 4, and 7, the locking body 26 is made of, for example, a substantially trapezoidal metal plate member, and each edge portion side corresponding to the door portion of the ceiling wall portion 12 a of the main body 12. Is attached to a vertical shaft 30 attached at substantially the center of the shaft so as to be rotatable about the axis. The locking body 26 is pivotally supported by a shaft 30 in the vicinity of one corner of both corners on the lower bottom side, which is the long side, and freely rotates in a horizontal plane so that the door portion 14 is in an open state and a closed state. The rotational position is changed correspondingly. When the door portion 14 is moved upward, the upper bottom side, which is the short side of the locking body 26, is positioned around the axis so as to advance in a crossing manner with respect to the vertical movement surface of the door portion 14. The lower side of the door part 14 is received from below and the open state of the door part 14 is maintained. On the other hand, as shown in FIGS. 5 and 8, the locking body is rotated so that the upper bottom side of the locking body 26 is moved to the position around the axis so as to be retracted from the moving surface of the door portion. The locking of the door in the open state by the body is released, and the door 14 drops due to its own weight and enters the closed state. In this embodiment, since the locking body is formed in a trapezoidal shape and locks the door portion on the upper bottom side, the locked state can be released with a small rotation angle. Further, a lever member 32 extended to one side along the side direction of the lower bottom is integrally fixed to the locking body 26. The lever member 32 is made of a flange member such as iron bent in an L shape on the extended end side, and is fixed by welding or the like, and rotates integrally with the locking body 26 with the extended end portion as a free end. As will be described later, the extended end side of the lever member 32 is linked to the mechanical operating body 28 via the rope 40. In addition, if the latching body 26 uses the axis | shaft 30 as a fulcrum, the connection part with the mechanical action body of the lever member 32 will become an action point, and the part which receives a door part will become a power point. In this embodiment, the distance from the fulcrum to the action point is sufficiently longer than the distance from the fulcrum to the force point, and the latching body can be operated only by applying a relatively small force to the action point according to the lever principle. . As a result, the mechanical operating body that releases the locked state of the locking body can be realized with a simple configuration with a relatively small operating force such as a biasing device 42 described later. The shape of the locking body 26 may be arbitrary, and may be, for example, a triangle, a rectangle, a semicircle, a circle, an ellipse, or any other shape as long as the open state and the release state thereof can be configured by rotating around the axis. Further, the configuration is not limited to the configuration around the vertical axis but may be configured to be rotatable around the horizontal axis. Further, the locking body is not limited to a mode of locking the lower edge side portion of the door portion, and may be, for example, an intermediate position in the height direction of the door portion or an arbitrary position such as an upper side and a left and right side portion in the width direction. . Moreover, a latching body is good also as a structure of not only rotation around an axis | shaft but linear slide movement, for example.

  As shown in FIGS. 4 and 5, in this embodiment, the machine operating body 28 is accommodated in a flat rectangular box-shaped case 34 fixed on the top wall portion 12 a of the bag main body 12, and its center is in the vertical direction. It consists of a disk-shaped rotating member 38 that is supported by a rotating shaft 36 so as to be freely rotatable around the axis. In the present embodiment, the rotating member 38 and the lever member 32 of the locking body 26 are connected to each other via, for example, a wire 40 such as a metal wire, and one end side of each of the circumferential edges of the mechanical operating body 28 is mutually connected. The other end side is connected to the extended end portion of the lever member 32 while being connected to positions slightly separated from each other. The rotating member 38 entrains the rope 40 and rotates around the rotation axis 36 in the rewinding direction. The rotation member 28 is one operation operation such as a rotation operation in the winding direction of the rope 40, and pulls the lever member 32 to simultaneously rotate the two locking bodies around the axis so that the door portion 14 is locked. It is configured to be released. In addition, the machine action body may be arrange | positioned at the surrounding wall part 12b, for example, and other arbitrary places may be sufficient as it.

  The rotating member 38 is urged by an urging device 42 such as a coil spring so as to rotate in the winding direction of the rope 40. At the same time, the rotating member 38 is locked and held in a state where it is rotated in the rewinding direction against the urging force of the urging device 42, and the locked state is released by the detection of the sensing unit 16 to search the rotating member 38. It is linked to an interlocking device 44 that rotates in the winding direction of the strip 40. That is, the open holding mechanism 22 is engaged against the urging force of the urging device 42 and the urging device 42 that urges the rotating member 36 so that the door 14 is closed by the engaging body 26. And an interlocking device 44 that locks and holds the rotating member 38 at a position where the body 26 holds the door portion 14 in an open state, and operates the rotating member 36 by the detection of the sensing unit 16. In the present embodiment, the biasing device 42 is connected at one end side to an intermediate position of an operating lever 46 that is radially extended from the central axis of the rotating member 38 and integrally welded. And the other end side is connected with the receiving piece 35 of case 34, and the rotation member 38 is always urged | biased to the left rotation direction on FIG.

  As shown in FIGS. 7 and 8, the interlocking device 44 engages the end of the lever locking member 50 while being linked to the lever locking member 50 engaged with the extended end of the operating lever 46 and the sensing unit 16. And an activation device 52 for releasing the locking and the locking thereof. The lever locking member 50 is made of, for example, a metal L-shaped flange that is formed long toward one side and is bent in an L shape, and an annular portion 50b is formed at the end. The lever locking member 50 loosely engages the annular portion 50b around the single reinforcing bar 12a1 of the top wall 12a, and freely rotates around the reinforcing bar 12a1 with the extended tip as a free end. Yes. As shown in FIG. 7, the lever locking member 50 is rotated counterclockwise to move the operating lever 46 to the left while resisting the biasing force of the biasing device 42 along the L-shaped inner side. Then, as shown in FIG. 4, the rotating member 38 is rotated in the unwinding direction of the rope 40. Then, at the position where the L-shaped longitudinal side of the lever locking member 50 becomes substantially horizontal, the extension tip of the lever locking member 50 is locked by the activation device 52, so that the operating lever 46 resists the biasing force of the coil spring. Lock and hold. As shown in FIG. 8, when the locking state of the locking member 50 by the activation device 52 is released, the locking holding force is released, and the locking member 50 is forced by the biasing force of the biasing device 42. As shown in FIG. 5, the rotating member 38 is rotated in the rewinding direction of the rope 40 by being rotated clockwise. On the other hand, the activation device 52 switches between an upright state and a tilted state, and locks and releases the extended tip of the lever locking member 50. The activation device 52 includes, for example, a bracket 56 that is pivotally attached or sandwiched to a single reinforcing bar 12a2 to a certain degree and supported to be tiltable, and a roller that is supported by the bracket 56 via a horizontal axis. 54. The bracket 56 is linked to a weight of a sensing unit 16 to be described later and a rope 58 such as a metal wire. The bracket tilts around the reinforcing bar 12a2 via the rope 58 when the weight of the sensing unit 16 falls by gravity, and can stand upright and stand upright when no traction force is applied. The roller 54 is supported on the upper end side of the bracket 56, and is provided so as to be locked from the upper side of the extension tip of the locking member 50 in which the longitudinal direction of the bracket 56 is horizontally arranged in the upright state of the bracket 56. The roller 54 is in sliding contact with the locking member at a peripheral surface portion in a low friction state, and the bracket 56 is smoothly tilted when the bracket 56 is pulled. In addition, the rope 58 is engaged in the ring of the guide ring 60 loosely inserted in one rebar, and the traction force due to the weight is smoothly transmitted.

The escape door 76 is a strip-shaped metal plate locking handle that is rotatably supported around a vertical axis 79 fixed to a flat plate fixed to a reinforcing bar in the vicinity thereof and is arranged so as to sandwich the top wall portion vertically. The closed state is maintained via 80. When a child or the like escapes from the bag main body, the lock handle 80 is rotated around the vertical axis 79 and then the escape door is opened. Since the door portion is provided with a metal member, the door portion is heavy and cannot be easily opened by a child or the like, but can be easily escaped through the escape door. Thereby, since safety is ensured, it can be installed well near a house.

  As shown in FIGS. 6 and 10, the bag main body 12 is provided with a lock device 82 that holds the door 14 in a closed state. The locking device 82 includes a plurality of locking pieces 84 and 85 provided on the upper side of the door portion 14, and a downward U-shaped receiving rod 86 provided on the rod main body 12. The fixed lock piece 84, which is a single lock piece, is provided with a U-shaped opening downward, and is fixedly supported by a support leg 87 protruding upward from the upper side of the door portion 14. The movable lock piece 85, which is another lock piece, is provided with a handle portion 85a on the other end side while opening one side in a U-shape, and is rotatable so that the surface can be aligned with the fixed lock piece 84. It is connected to the shaft. As shown by the two-dot chain line in FIG. 10, when the door portion 14 is closed, the horizontal portion of the receiving rod 86 is inserted into the opening of the fixed lock piece 84. If necessary, when the movable lock piece 85 is rotated to the fixed lock piece side, the movable lock piece 85 U-shaped opening portion closes the catch 86 from below, and locks and holds the closed state of the door portion. Can do. Thereby, for example, when the capture device is transported, the door portion does not move up and down, so that it can be transported stably.

  Next, the operation of the animal capturing apparatus 10 according to the present embodiment will be described. For example, the capture device 10 is transported and installed near a house or a field or in a forest. The door part 14 provided in the adjacent 2 surface part among the surrounding wall parts of the coffin main body 12 is raised along the guide rail 20, and the coffin main body is opened. In this open state, the locking body 32 is rotated and advanced so as to receive the raised lower edge frame of the door portion, and the open state of the door portion is maintained. At this time, the rotating member 38 is latched and held via the interlocking device 44 at a rotational position around the shaft 30 in the rewinding direction of the rope 40 linked to the latching body against the biasing force of the biasing device. Yes. At the same time, the weight 64 of the sensing unit 16 is placed on the contact body 62. In the space S of the bag main body 12, a bait K is placed in the vicinity of the corner of the peripheral wall portion 12 b serving as a closed wall portion and in the vicinity of the hanging position of the contact body 62. As described above, since the opening is formed in the adjacent two surface portions in the bag body 12, the continuous opening area can be secured widely, and at the same time, there is a distance from the position where the feed K is placed to the door portion and the capture space. Can be secured widely. As a result, the alertness felt by the beasts W such as pupae is reduced, and it is easy to enter the cocoon body, and a plurality of beasts can enter the cocoon body at the same time. As a result, the monsters can be captured efficiently. Further, the apparatus can be reduced in size and weight. When the beast W entering the main body touches the contact body 62, the contact body 62 swings and the weight 64 falls by its own weight. Then, as shown in FIG. 8, the activation device is tilted via the rope 58 linked to the weight, and the locking state of the operation lever 46 is released. As shown in FIG. 5, the urging force of the urging device 42 causes the rotating member 38 to rotate in the winding direction of the cable 40, and the lever 40 of the locking body 32 is pulled by the cable 40 to lock the cable 40. The body turns to the closed position of the door. When the locked state by the locking body 32 is released, the door portion falls by its own weight along the guide rail 20 and closes the opening of the bag main body. By simultaneously closing the two continuous doors in this manner, the beast W in the cage body can be reliably captured.
