Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a cage for capturing relatively large animals such as boars, deer and bears, as well as relatively small and light birds and beasts such as monkeys, raccoons and crows.

[0002]

[Prior art]

 As this kind of prior art, for example, there is one disclosed in Japanese Patent Application Laid-Open No. 8-56549. That is, in this prior art, a bottom plate is movably provided at the bottom of the cage body, and a locking means capable of locking the drop door of the cage body at the open position is provided, and furthermore, between these bottom plates and the locking means. A catching cage is constructed by providing a release means. The bottom plate is rotatably supported by the cage body via a support shaft. The locking means includes a locking member that holds the drop door at the open position via a roller, a vertically movable member that regulates the movement of the locking member, and a base end of the locking member pressed against the vertically movable member. And a first spring. The release means includes the above-described elevating member, a connecting member that connects the elevating member and the bottom plate, and a second spring that constantly presses the elevating member upward through the connecting member. .

[0003] In the trap cage configured as described above, when in the normal state, the bottom plate is held in a substantially horizontal state via the connecting member by the pressing force of the second spring, and the elevating member is moved to the upper position. is there. At this time, the locking member is in a state where its base end is pressed by the elevating member by the pressing force of the first spring, and its distal end is located below the falling door and holds the falling door in the open position. doing.

When an animal enters the cage body from this state, the load causes the bottom plate to rotate downward against the pressing force of the second spring, and the elevating member descends. When the elevating member descends, the contact state with the locking member is released, and the locking member moves toward the base end by the pressing force of the first spring. As a result, the drop door held at the open position by the tip of the locking member descends due to its own weight, closing the opening of the cage body, and it is possible to trap the invading animal inside the cage body Becomes

[0005]

[Problems to be solved by the invention]

 In the case of the above-mentioned trap cage, in order to close the opening of the cage body by the dropping door, the elevating member descends until the contact state with the locking member can be released, and the locking member faces the base end side. Need to move. In other words, even if the elevating member descends, if the amount is insufficient, the state of contact with the locking member cannot be released, so that the opening of the cage body cannot be closed. .

[0006] The descending amount of the elevating member increases or decreases according to the amount of rotation of the bottom plate. Therefore, when relatively large animals such as boars, deer, and bears invade, the amount of rotation of the bottom plate increases, and the elevating member descends sufficiently, and these can be confined inside the cage body. It will work.

However, when relatively small and light birds and beasts such as monkeys, raccoon dogs, and crows invade, the amount of rotation of the bottom plate becomes small, and the lowering of the elevating member becomes insufficient. Can not be trapped inside.

In order to solve such a problem, it is conceivable that the locking member is brought into contact with the lifting member so that the locking member can be moved even when the lifting member is slightly lowered. . However, in the case of the above configuration, there is a possibility that the contact state between the lifting member and the locking member may be released only by the external force such as vibration or impact acting on the cage body. For this reason, malfunctions such as the animal to be captured touching the outer surface of the cage body to close the opening, or the dropping door descending when the animal has not sufficiently entered the cage body, etc. Frequent, making it difficult to capture birds and animals. In addition, once a malfunction occurs, the birds and beasts may become more vigilant and may not even approach the trap cage.

In view of the above circumstances, it is an object of the present invention to provide a trap cage that can reliably capture a relatively small and light bird and animal without causing a malfunction due to an external force. .

[0010]

[Means for Solving the Problems]

 In the present invention, a cage body having openings at front and rear ends thereof, a pair of shutters movably arranged in the vertical direction to open and close the openings of the cage body, and connected to these shutters An opening operation member for opening and moving the shutter when a pulling operation is performed; and an opening operation member disposed at the bottom of the cage main body to occupy the ascending position in a normal state and to the ascending position when a load is applied. When the movable body is displaced to the lowered position, the movable body is linked to the movable body, and when the movable body is at the ascending position, the opening operation member can be locked in a tensioned state. The trap cage is provided with a toggle type locking means for releasing the locked state of the opening operation member.

The cage body allows the shutter to move when retracted from the movement area of the shutter, and protrudes into the movement area when the shutter closes the opening of the cage body and moves the shutter. It is preferable to provide a stopper means for preventing the above.

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail with reference to the drawings showing embodiments. 1 to 3 show an embodiment of a catch cage according to the present invention. The capture cage 1 exemplified here has a rectangular cylindrical cage body 10 having left and right side walls 11 and 12, an upper wall 13 and a bottom wall 14, and having openings 15 and 16 at the front and rear, respectively. Each wall is provided with an outer frame 17 made of a thick metal square such as an angle material, and a grid 18 formed by welding a thin metal square to the inside of the outer frame 17 vertically and horizontally. These walls are formed in a rectangular cylindrical shape by assembling the outer frames 17 with connecting means such as screws, and can be disassembled and stored when not in use.

The cage body 10 is provided with guide means 20 at each of the front and rear openings, and a shutter 30 is provided at each guide means 20.

The guide means 20 has a gate shape including a pair of left and right slide guide members 21 extending in the vertical direction and a connecting member 22 for connecting between upper end portions of the slide guide members 21. A first pulley 23 is provided at the center of the connecting member 22. The slide guide member 21 is a thick metal material having a U-shaped cross section and a length greater than twice the height of the cage body 10, and the U-shaped openings are opposed to each other. It is provided in a state. The connecting member 22 is made of a thick metal square like the outer frame 17 of the wall.

The shutter 30 includes an outer frame 31 and a lattice 32 similarly to the wall of the cage main body 10, and is configured to have a size capable of closing the openings 15 and 16 of the cage main body 10. Each of the shutters 30 has both right and left edges fitted in a U-shaped portion of the slide guide member 21, and can move in the vertical direction using the slide guide member 21 as a guide. A wire 40 is connected to each of these shutters 30 at the center of the upper edge as an opening operation member. The wires 40 are connected to each other after the first pulley 23 of the connecting member 22 is wound, and furthermore, a ring 41 is formed at the distal end thereof.

As shown in FIG. 3, a stopper member 50 is provided between the guide means 20 and each shutter 30 as a stopper means. The stopper member 50 is formed by integrally forming a stopper claw 51 and a weight 52, and further provided with a support shaft 53 at a position above the stopper claw 51. The stopper claw 51 is provided with a shutter 30. The slide guide member 21 is swingably supported by a slide guide member 21 via a support shaft 53 in such a manner as to protrude into and retract from the movement range of the slide.

Further, the cage body 10 is provided with a movable body 60 at the center inside the cage body 10. The movable body 60 is formed of metal or wood into a flat plate shape, and is rotatably supported on the bottom of the cage main body 10 about a horizontal axis by a shaft 61 provided at one end thereof. As shown in FIG. 2, a coil spring 62 and a connecting rod 63 are provided at the other end of the movable body 60. The coil spring 62 is interposed between the side wall 11 of the cage body 10 and, as shown in FIG. To maintain. The connecting rod 63 is a rod having a screw portion 63a at the distal end, and is swingably supported on the upper end of the movable body 60 via the proximal end.

Further, the cage body 10 is provided with a locking means 70 comprising a lock body 71 and a four-bar link 72 on the side wall 11 near the tip of the movable body 60.

The lock main body 71 is a thick metal square member having an L-shaped cross section, and is fixed to the central portion of the side wall 11 by welding.

The four-bar link 72 includes a first link 72a fixed to the bottom surface of the lock body 71, and a second link supported at a lower end on the outer side of the first link 72a via a first shaft 72b. 72c, a third link 72e supported at the lower end on the inner side of the first link 72a via a second shaft 72d, and a third shaft 72c connecting between the second link 72c and the third link 72e. 72f and a fourth link 72h supported via a fourth shaft 72g, and these links constitute a toggle mechanism. That is, as is clear from FIG. 2A, when the first shaft 72b and the third shaft 72f are arranged along the vertical direction with respect to each other, the four-bar link 72 is connected to the second shaft 72b. An extension of a line connecting the second shaft 72d and the fourth shaft 72g passes between the first shaft 72b and the third shaft 72f. In this state, a so-called self-lock is acting on the second link 72c, and the second link 72c cannot swing around the axis of the first shaft 72b. In this self-locking state, if the fourth link 72h is slightly swung down around the axis of the third shaft 72f, the third link 72e is swung down around the axis of the second shaft 72d. As a result, the second link 72c swings largely downward about the axis of the first shaft 72b.

The four-bar link 72 is provided with extended portions 72j and 72k on the second link 72c and the fourth link 72h, respectively. The extended portion of the second link 72c (hereinafter, referred to as a second link extended portion 72j) is a portion that extends from the second link 72c to the outside of the cage body 10 along the horizontal direction in the self-locking state described above, A stopper shaft 73 is provided at the tip. The stopper shaft 73 is attached so as to extend in the vertical direction in a self-locked state, and the upper end thereof is in contact with the bottom surface of the lock body 71. The extended portion of the fourth link 72h (hereinafter, referred to as a fourth link extended portion 72k) is a portion extending from the fourth link 72h to the inside of the cage body 10 along the horizontal direction in the self-locking state described above, The distal end of the connecting rod 63 is connected to the distal end.

When birds and beasts are captured by the capturing cage 1 configured as described above, after the cage main body 10 is disposed in an animal path or the like, the shutters 30 are moved upward to open the openings 15, 15 of the cage main body 10. Then, as shown in FIG. 1A, the ring 41 of the wire 40 is inserted through the stopper shaft 73 to put the four-bar link 72 into a self-locking state. In this state, since the movement of the wire 40 is blocked by the stopper shaft 73, the shutter 30 is suspended by the wire 40, and the state where the openings 15, 16 of the cage body 10 are opened is maintained. In addition, the stopper member 50 tilts upward against its own weight when the stopper claw portion 51 contacts the shutter 30. During the above-mentioned operation, according to the above-described trapping cage 1, even when vibration or impact is applied to the cage main body 10 by touching by an operator or the like, the four-bar link 72 is in a self-locking state. In addition, the ring 41 of the wire 40 does not come off from the stopper shaft 73, so that the work can be performed easily.

Next, the bait that the bird or animal to be captured prefers is put in the cage main body 10, preferably in the central portion, and waits. In this case, it is preferable to camouflage the movable body 60, the lock means 70, the cage body 10, the shutter 30, and the wire 40 with plants and trees.

When a certain period of time elapses from the above-described state, the birds and beasts approach the capture cage 1 due to the smell of the bait, and attempt to enter the cage body 10 while being alert. Even in this state, according to the capturing cage 1, the self-locking of the four-bar link 72 prevents the ring 41 of the wire 40 from coming out of the stopper shaft 73 carelessly. However, even if an impact is applied to the cage body 10 at the time of intrusion, the openings 15 and 16 of the cage body 10 will be kept in an opened state continuously, and there is a possibility that the birds and animals may miss and escape. Absent.

When the birds and animals enter the cage 10 in order to eat the food, the movable body 60 is subjected to the load of the birds and animals when the legs are placed on the movable body 60 as shown in FIG. As a result, the fourth link 72h of the four-joint link 72 swings downward around the axis of the third shaft 72f via the connecting rod 63. As a result, the self-lock of the four-bar link 72 is immediately released, and the second link 72c swings downward around the axis of the first shaft 72b. In this case, even if the lowering of the movable body 60 is very slight, after the self-lock is released, the second link 72c and the fourth link 72h largely swing downward due to their own weights. Become like As a result, the ring 41 of the wire 40 comes out of the stopper shaft 73 without fail, so that the shutter 30 falls down rapidly by its own weight, and the openings 15 and 16 of the cage body 10 are simultaneously closed. Invading birds and beasts can be trapped inside. Further, when the shutter 30 moves downward, as shown in FIG. 3B, the stopper member 50 tilts downward by its own weight, and each stopper claw 51 comes to protrude into the movement area of the shutter 30. Even if the shutter 30 is operated, it can no longer be moved upward. Therefore, even if the trapped birds and beasts are violently violent and the cage body 10 falls, there is no danger of missing the cage body 10.

[0026]

[Effect of the invention]

 As described above, according to the present invention, since the toggle type is used as the means for locking the shutter via the opening operation member, even if a very small load acts on the movable body. Even if there is a lock, the locked state will be released immediately and reliably, and it will be possible to capture relatively small and light birds and animals. However, as long as the movable body does not move, the lock is not released by the self-locking of the toggle type locking means, and there is no risk of malfunction even when an external force such as vibration or impact is applied to the cage body, for example. .
