Description

  The present invention relates to a cage for capturing small animals, and more particularly to a cage for capturing raccoons.

  In recent years, the population of raccoons has increased in Japan. This is because there is no natural raccoon enemy in Japan, omnivorous and small mammals, wild birds and their eggs, fish, amphibians, reptiles, insects, fruits, vegetables, cereals, etc. As a result, it is said that it is possible to live in a wide range of environments from forests and wetlands to urban areas.

  With such an increase in the number of individuals, various damages caused by raccoons are occurring frequently. Specifically, this includes damage to crops that eat and destroy crops, damage to the living environment that invades and propagates into the attic of people's houses, and eats and destroys garbage. In addition, since it is a major vector for rabies in North America, there is also concern about the possibility of vector-borne infection. Furthermore, there are concerns about behaviors that prey on and reduce native species (frogs, wild bird eggs, chicks, etc.) and take away habitat as a result of competing with native species (raccoon dogs and foxes). There is concern about the influence of the system. Therefore, various measures for controlling raccoons have been taken. As specific capture methods, capture by a box trap and capture by an egg trap (trade name) are generally performed.

  A general box basket is provided with an entrance for attracting animals to a main body for storing animals, and a door for opening and closing the entrance is provided so as to be horizontally or vertically rotatable with respect to the main body. The door is urged by a spring in the direction to close the entrance. With the entrance open, the door is temporarily locked, waiting for the animal to enter the body, and the animal enters the body to enter the body. The structure that can capture the invading animal by releasing the locking state of the door and rotating the door by the elastic action of the spring and closing the entrance with this door at the moment when the animal is poking the food attached to the trigger It has become. As an improved invention relating to such a box cage, there is an invention described in JP-A-2005-87072.

  On the other hand, the egg trap (made by Egg Trap Co., US Pat. No. 4,633,610), which was developed to capture raccoon exclusively, is a trigger that allows the raccoon to put the forelimb (hand) through the opening at the bottom of the body. The spring catch is released by grabbing and pulling forward, and the forelimb is held by the rod-shaped capturing part integrated with the spring pressing the palm.

United States Patent Publication No. 4,633,610

  The egg trap has the following advantages.

  (1) Bycatch of animals other than raccoons can be prevented.

  (2) It is possible to reduce prey escape and malfunction rate by small animals.

  (3) Capable of capturing individuals who are highly alert to the box cage.

  (4) Costs related to purchasing, transporting and managing firewood can be reduced.

  (5) The installation environment is highly selective and can be installed in watersides and wetlands.

  However, in order to set the egg trap, it is necessary to move the rod-shaped catching portion biased by a strong spring to the locking position by the spring catch. Such work requires a dedicated tool and a strong force, which is dangerous and tends to require a large amount of labor for setting.

  Moreover, since the forelimb of the raccoon is intensely pressed by the capturing part, the pain given to the captured raccoon becomes enormous.

  Therefore, the present invention has the advantages of the egg trap, but is easy to set, and has little pain on the captured raccoon, and other small animals that can capture small animals with similar behavior to raccoons. The purpose is to provide a vase.

  In order to solve the above problems, the raccoon kite according to the present invention is configured as follows.

    Claim 1: A raccoon is placed in a cylindrical part for inserting a forelimb, a trigger is provided at the tip of the cylindrical part and is swingably attached to the substrate part, and is swingably attached to the substrate part. A stopper member that is attached and released from the locked state by swinging the trigger, and a locking part that is free from the rotation-prevented state by swinging the stopper member and that is rotatable and locks the binding band. A rod-shaped winding member, a bundling band that is locked to the locking portion of the winding member and mounted in a ring shape on the base, and an elastic body that imparts a rotational force to the winding member; The trigger and stopper members are swingably mounted on the board, and the housing is equipped with the board and winding member. Equipped with a plate-shaped base part, a cylindrical part, a trigger, a stopper member, a winding member, a binding band, an elastic body, a substrate part and a base part, and a hole that matches the cylindrical part is provided. And a fixed string attached to the housing.

    [2] A raccoon scissor according to [1], wherein the raccoon scissor is mounted so as to be swingable with respect to the substrate portion, and is released from the locked state when the trigger swings; A stopper member is formed by a plate-like stopper piece that is swingably attached to the substrate portion and whose swinging motion is controlled within a certain range by abutting the swinging piece, and further winding By making the take-up member abut on the stopper piece, the take-up member can be rotated in the direction in which the restoring force is applied to the elastic body, but is prevented from rotating in the direction in which the restoring force is released.

    Claim 3: In the raccoon scissors according to claim 1 or 2, a curved guide part is provided on the base part to keep the binding band in a ring shape.

    Claim 4: In the raccoon scissors according to any one of claims 1 to 3, a cutter member is provided on the base.

  Raccoons are not good at visual acuity and have the habit of checking food by hand. In order to capture using such behavior, in the present invention, a cylindrical portion for inserting a forelimb is provided in the housing, and a trigger for attaching a bait is provided in front of the tubular portion. The raccoon puts his forelimb into the tube and pulls the trigger to touch the decoy bait. Then, the winding member for winding the binding band rotates, and as a result, the binding band is tightened and the forelimb of the raccoon is captured.

  Thus, the present invention is a trap that uses the behavior of a raccoon, can prevent other small animals such as cats from being mistakenly captured, and can reduce the carry-away and malfunction rate of food by small animals. is there. In addition, since it is not a large bag like a box kite, it is possible to capture an individual who is wary of a large device.

  Furthermore, the cost associated with purchasing, transporting, and managing the cocoons can be reduced because the cocoons are smaller than the caskets. Moreover, since it can be installed simply by fixing with a string, it can also be installed in watersides and wetlands.

  In the present invention, since it is captured using a member that cannot be loosened once it is tightened, it is not necessary to keep tightening the raccoon's forelimbs intensely like an egg trap, and the pain given to the captured solid can be reduced. It is. Similarly, it is not necessary to urge the catching part with a strong spring like an egg trap, so the setting becomes easy.

  As shown in FIG. 1, a raccoon scissors according to the present invention includes a housing 1, a plate-like base portion 2 provided in one housing 1, and a plate-like substrate portion 3 suspended on the base portion 2. A cylindrical portion 13 attached under the base portion 2, a substantially L-shaped trigger 4 attached to the substrate portion 3 so as to be swingable, and a plate shape attached to the substrate portion 3 so as to be swingable. Oscillating piece 5, plate-like stopper piece 6 slidably attached to the substrate portion 3, a rod-like winding member 8 provided penetrating the base portion 2, and rotating to the winding member 8 An elastic body 9 for applying a force, a fixed string 10 attached to the housing 1, and a binding band 11 not shown in FIG.

  The housing 1 is composed of two cylindrical bodies 1 a and 1 b, both of which are provided so as to be opened and closed by a hinge 14. The means for integrating the cylindrical bodies 1a and 1b is not limited to such a hinge, but may be a method of cutting a screw groove and fitting both of them, or any other method.

  The housing 1 is made of a metal that does not rust, such as stainless steel, but a synthetic resin such as plastic can also be used. The cylindrical shape in the cylindrical bodies 1a and 1b is a broad concept, and the shape may be a cylindrical shape, a prismatic shape, an egg shape, or the like.

  A fixed string 10 is attached to the cylindrical body 1a. This fixing string 10 is used for fixing the bag main body according to the present invention. In other words, the heel body is fixed to the rod or tree branch driven into the ground by the fixed string 10 to prevent the raccoon on the heel from escaping together with the heel body.

  The plate-like pedestal 2 is mounted in the cylindrical body 1b. A substrate part 3 is erected on one side (tubular body 1a side) of the base part 2, and a cylindrical part 13 is attached to the other side (tubular body 1b side).

  The cylindrical portion 13 is a hollow cylindrical material, and one opening matches the hole 12 provided in the housing 1b, and the other opening matches the hole 2b provided in the base portion 12.

  The substrate portion 3 erected on the pedestal portion 2 is a plate-like body, and a trigger 4, a swing piece 5 and a stopper piece 6 are swingably attached. Here, the trigger 4 swings around the swing shaft 4 c, and the swing piece 5 and the stopper piece 6 swing around the swing shaft 15.

  The trigger 4 is formed by bending a plate material into an L-shape, and is provided with a bar member 4 b that is locked to a notch 5 a provided in the swing piece 5. A tension spring 16 is interposed between the trigger 4 and the substrate portion 3, and when the trigger 4 is pulled downward, it is biased in a direction to return to the original position.

  The stopper member 7 according to the present invention is composed of the swing piece 5 and the stopper piece 6 and functions to prevent the winding member 8 from rotating.

  Here, the oscillating piece 5 is a plate material, and has a notch 5a at the top thereof. The notch 5a has a substantially L shape, and a bar member 4b that forms the trigger 4 is locked to the bent end. The stopper piece 6 is a plate material, and a bar member 6a capable of coming into contact with the swing piece 5 is provided on the top thereof.

  An elastic body 17, which is a torsion coil spring, is interposed between the swing piece 5 and the stopper member 6, and urges the stopper piece 6 to swing in a direction in contact with the swing piece 5.

  The winding member 8 is a rod-like body, and penetrates the base portion 2 so as to be rotatable. An elastic body 9 is interposed between the base portion 2 and the winding member 8 or between the winding member 8 and the winding member support 18. One end of the elastic body 9 is attached to the winding member 8, and the other end is attached to the base 2 or the winding member support 18. Here, the winding member support 18 is a bent plate-like body, and its end is fixed to the base 2. Thus, since the elastic body 9 is interposed between the base portion 2 and the winding member 8 or between the winding member 8 and the winding member support 18, the winding member 8 is made to be an elastic body. If it is rotated in a direction in which a restoring force is applied to 9, it is possible to apply a restoring rotational force to the winding member 8.

  The elastic body 9 uses a coil spring in FIG. 2, but its action is the same as that of the mainspring spring. That is, by rotating the winding member 8, the coil diameter is reduced, that is, a restoring force is applied, and the winding member 8 can be rotated. The elastic body 9 may be an ordinary mainspring spring without using the coil spring shown in FIG.

  A hexagonal column-shaped recess (not shown) is provided at the bottom of the winding member 8 and is rotated by a hexagon wrench 19 to give a restoring force.

  The specific action of the stopper member 7 preventing the winding member 8 from rotating is as follows. As shown in FIGS. 2a and 2b, the swing piece 5 is prevented from swinging when the notch 5a and the bar member 4b of the trigger 4 are locked, and the stopper piece 6 is a bar member 6a provided on the top. Is in contact with the swinging piece 5 so that the swinging is controlled within a certain range. That is, the stopper piece 6 is provided so as not to swing in the direction of the swing piece 5 beyond the state shown in FIG.

  By controlling the swing of the stopper piece 6 in this way, the rotation of the winding member 8 is prevented. That is, as shown in FIG. 2 a, the bar member 8 a provided at the upper end of the winding member 8 abuts on the lower end 6 b of the stopper piece 6, and the stopper piece 6 abuts on the swing piece 5, so that FIG. Since it cannot swing in the direction of the swinging piece 5 beyond this state, the winding member 8 is prevented from rotating. The elastic body 9 rotates in the direction in which the winding member 8 swings the stopper piece 6 away from the swing piece 5 (see FIG. 2b) (counterclockwise when viewed from the swing piece 5 side in FIGS. 2a and 2b). By doing so, it is interposed so that a restoring force is applied. When rotating counterclockwise, since the stopper piece 6 can swing as shown in FIG. 2b, the winding member 8 can rotate, but it rotates counterclockwise (clockwise), that is, is restored. The rotation based on the force is prevented by contacting the stopper piece 6 as described above.

  Thus, the restoring force of the winding member 8 generated by rotating counterclockwise is maintained by the stopper member 7, but the restoring force is released by the swing of the trigger 4. That is, a bait for attracting a raccoon is attached to the bent portion 4a of the trigger 4, but when the raccoon touches and grabs the bait, the trigger 4 swings downward and the rod member 4b swings downward. Then, the bar member 4b fitted into the bent end of the notch 5a is released from the fitted state. As a result, the swing piece 5 can swing. The rotational restoring force of the winding member 8 is that the swing of the swing piece 5 is prevented, the swing of the stopper piece 6 is prevented, and the rotation of the rod member 8a contacting the lower end 6b is thereby prevented. Maintained. However, when the swinging piece 5 can swing, the maintenance of the restoring force is released and the winding member 8 rotates.

  In the present invention, the binding band 11 is tightened by using the rotational force of the winding member 8, and the forelimb of the raccoon is captured.

  Here, the binding band 11 uses a product that is widely used for binding cables in an electronic device, also called a cable tie, and is widely available on the market. As shown in FIGS. 7a and 7b, the binding band 11 includes an elongated band-shaped band portion 11a and a head portion 11b provided at one end in the longitudinal direction of the band portion 11a and capable of locking an arbitrary portion in the longitudinal direction of the band portion 11a. Is. A number of locking grooves 11c are provided in the band portion 11a. The head portion 11b is provided with a locking claw 11d provided with a step. Although it is possible to insert the leading end of the band portion 11a from above the head portion 11b in FIG. 7c, when the inserted band portion 11a is pulled out, the locking groove 11c and the locking claw 11d are locked and pulled out. The structure is not possible.

  A method of attaching the binding band 11 having such an action to the raccoon scissors according to the present invention will be described with reference to FIG.

  On the base part 2, a guide part 21 which is a wall body having a curved shape is provided. A band portion 11 a is provided in a ring shape along the guide portion 21. The tip of the band portion 11 a is inserted through a hole 3 a provided in the substrate portion 3, and further inserted into a locking portion 8 b that is a groove provided in the upper portion of the winding member 8. In the middle, the band portion 11a is inserted through the head portion 11b, and the binding band 11 is tightened by the rotation of the winding member 8. In this way, the forelimb of the raccoon is captured by being tightened to a ring shape having a smaller diameter than the original ring shape. As described above, since the binding band 11 has a structure that does not loosen once it is tightened, it is impossible for the raccoon that has captured the forelimb to remove the forelimb from the heel according to the present invention.

  Further, according to the present invention, the binding band 11 tightened at the time of capture or the like can be easily excised. Specifically, as shown in FIGS. A and b, the binding band 11 is cut by a cutter member 20 provided on the base 2. The cutter member 20 includes a swingable swinging piece 20a and a blade portion 20b attached to the swinging piece 20a. The swing piece 20a is attached to a plate member 22 standing on the base 2 so as to be swingable by a shaft 20c. The blade 20b is attached to the end of the swing piece 20a with a screw, and can be easily replaced by loosening the screw. This blade part 20b is provided in the position which comes to the upper part of the attached binding band 11. FIG.

  In the following, an outline is given in accordance with a specific method of use.

  FIG. 6 is an overall view of a raccoon kite according to the present invention. The main fence is set by tying it to a pile provided near the raccoon habitat or a self-generated branch by a fixed string 10 attached to the housing 1. The raccoon puts the forelimb through the hole 12 provided in the housing 1, tries to take the bait attached to the trigger 4 provided at the tip of the tubular portion 13 in the housing 1, and pulls the trigger 4. Then, the binding band 11 is tightened to capture the forelimb, and as a result, the raccoon can be captured.
