Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is for the purpose of catching and exterminating animals which cause damage to rats, weasels or other foods and crops, and carry pathogens, or for the purpose of hunting hares,
The present invention relates to an improvement of a trap used for catching wild dogs.

[0002]

2. Description of the Related Art Animals targeted for extermination of this kind are roughly classified into a method of directly poisoning by mixing a poisonous drug with food and the like, and a method of catching with a trap and then drowning this. Or, it is burnt to death. Poisoning
There is no problem in the killing power itself, but the human body (including infants)
It is rarely used in recent years because it has a problem in handling and use due to a large influence on the above, and it is difficult to prepare various conditions for feeding a poisonous substance conveniently. Further, there is also a problem that the captured animal is cunning and does not die even if it eats some poison, so that its generation is changed and the poison is resistant to the poison and the effect is not improved.

On the other hand, methods of capturing by using mechanical or electrical means and then killing by appropriate means are diverse in terms of safety to human body and convenience in handling, and various improvements are made. A proposal has been proposed. In the case of hunting, of course, poisonous drugs cannot be used not only in the case of live catch but also in the case of food.

The present inventor has previously proposed, in Japanese Utility Model Publication No. 1-8126 (utility model registration No. 1793864), a catching tool capable of catching a mouse or the like by a mechanical operation of this kind.

[0005] In a conventional catching tool, a mouse or the like enters the inside of the catching tool by being intruded by the bait installed in the body of the catching tool, and the movement of the rat at the time of this invasion or the movement of the rat when eating the bait is utilized. , The method of shutting off the door of the entry way was adopted. Therefore, when one mouse invades inside and bites the bait and the door is cut off, only one mouse can be caught unless the mouse continues invading inside.

The most significant feature of the above-mentioned utility model proposed by the present inventor is that, as a method for capturing the trap, any number of traps can enter the trap, and when a mouse invading the inside tries to go out. It is the point that the door was shut off for the first time, and as a result, it is possible for parent mice to invade, and child mice that were safe when they saw eating were able to invade at intervals. As a result, it was possible to realize a state in which a large number of mice invaded inside at once, enabling large-scale capture.

The above-mentioned invention proposed by the present inventor is epoch-making in that it enables a large amount of capture, but it adopts a complicated structure in which a link mechanism is used for the door opening / closing structure. However, there is a drawback that the manufacturing cost is high, and furthermore, when the first mouse invades, the door is closed as soon as this mouse passes through the door, so that the following mouse is a little. When you try to enter in succession at a time interval (a little longer time is fine) (when it is like a parent mouse and a child mouse), the first mouse activates the link mechanism that closes the door, There is a problem that you will be surprised by the loud sound that the car collides with the frame of the main body, or you will be surprised by the movement of the door standing up and you will escape from the place, originally, it is easy to intrude at all times and prevent it from escaping to the outside You In spite of being adopted is a new idea, there has been a drawback that the advantage can not be sufficiently exhibited.

[0008] Therefore, the inventor of the present invention is capable of catching a large number of mice at one time without being able to easily escape to the outside once invading, while smoothly invading the large number of mice. In order to make the structure simple, the patent application issued on August 21, 1992 (Japanese Patent Application No. 4-265282).
No.), at least one entrance is provided in the main body,
A trap having an opening and closing mechanism for opening and closing the entrance, wherein the opening and closing mechanism is configured such that one end of the door is rotatably provided around a horizontal axis and a tread plate for operating the door is provided. It is located inside the main body with respect to the door and juxtaposed with each other, and is pivotally attached about the middle of the tread plate so as to be swingable, and
The door is configured such that the tip end portion thereof has a length exceeding the pivot axis of the tread plate, and when the tip end of the door is stepped downward during operation, the base end side of the door is near the pivot axis of the lower side of the door. Proposed was a means for contacting with a cam surface to pivotally displace the door upward, and normally to pivotally return the door to a substantially horizontal state to restore the footboard to a substantially horizontal state. .

[0009]

However, in the technique of this proposal, in order to swing the door, the door is lifted upward by a prying action using the footboard as a lever. That is, when the front edge of the tread is brought into contact with the lower surface of the door and a rat or the like rides on the tread from the inside of the trap, the front edge of the tread is
As the point of action, it was pushed up against the lower surface of the door, and the entrance was closed by the rising of this door.

Due to such a structure, there is a problem that the rising angle of the door changes greatly even if the front end of the tread and the contact lower surface of the door are slightly deformed. Was difficult to do. The deformation of both means the occurrence of a catching phenomenon at the contact portion between the door and the footboard at the same time, and there is a possibility that the standing door cannot be smoothly returned to the original position. Further, since the door is always on the footboard, there is a problem that the weight of the door is applied to the footboard as it is, and the sensitivity of operation when a rat or the like steps on the footboard becomes dull. In view of such a problem, the present invention cannot prevent a mouse or the like that has entered the trap (allows a large number of successive entries).
In such a catcher, it is an object of the present invention to make it possible to open and close the plate-like door lightly and surely while having a simple structure for opening and closing the plate-like door.

[0011]

In order to achieve the above-mentioned object, the trap according to the present invention is provided with at least one entrance 2 in the main body 1 of the trap, and the entrance 2 is opened / closed by an opening / closing mechanism 4.
A trap that can be opened and closed by means of the opening / closing mechanism 4
The plate-like door 5 is swingably provided around the horizontal axis 6 extending in the width direction of the entrance 2 by a seesaw method, and the front end of the plate-like door 5 is centered on the horizontal axis 6. The side of the step 5b is made long and the side of the rear end 5a is made short, and the front end 7b of the tread 7 is foldably connected to the rear end 5a of the plate-like door 5 to form the rear end 7a of the tread 7. respectively spring 9 and 10 provided on the lower side of the front end 5b of the plate-like door 5 and the lower, the present
A locking projection 8 is provided on the bottom of the body 1 so that the rear edge 7a of the step plate 7 is above the locking projection 8 and slightly beyond the locking projection 8 when the stepping plate 7 is released. When the plate-shaped door 5 is stepped on, the rear edge 7a of the step plate 7 is located on the front side of the locking projection 8, and thus the step of the step plate 7 causes the plate-shaped door 5 to move. By taking a means of swinging around the horizontal axis 6 to substantially close the entrance 2 of the main body 1 and opening the entrance 2 by releasing the depression of the tread plate 7. is there.

Further, it is preferable that the step plate 7 and the plate-like door can be bent freely by pivotally connecting them.

In the present invention, the stepping plate 7 and the plate-shaped door 5 can be bent freely in addition to the pivotal support of both of them.
For example, when both are made of a flexible material such as plastic, bending due to the characteristics of the material may be used, or an appropriate means such as a hinge may be used. Further, the lower side of the front end portion 5b of the plate-like door 5 may be the bottom portion of the trap, the open field, or the floor of the building. Further, the elastic bodies 9 and 10 provided on the lower side of the step board 7 and the plate-like door 5 are
It may extend from the footboard 7 and the plate-shaped door 5, or may extend upward from the bottom plate side of the main body 1. Further, the locking protrusion 8 has the same structure, and the same effect can be obtained even if the locking recess is formed.

[0014]

According to the present invention, when a rat enters, for example, when the weight is applied to the plate-like door 5 of the main body 1, the plate-like door 5 is attached to the bottom of the front end 5b or the open field or the building. It is supported by the abutment with the floor and the horizontal axis 6 that pivotally supports the rear end portion 5a, and allows the mouse to enter the main body 1. Next, as shown in FIG. 3, when a rat puts his foot on the footboard 7 in order to get out of the main body 1, the footboard 7 bends at the joint with the plate door 5, and the plate door 5 swings around a horizontal axis 6 like a seesaw and raises the front end 5b of the plate-like door 5 to substantially close the entrance 2 of the main body 1.

As described above, since the step plate 7 and the plate-shaped door 5 are constructed so as to be freely bendable, the intrusion opening can be securely carried out without causing the uncertain operation unlike the above-mentioned prior art. Can be closed. Further, since the step plate 7 and the plate-like door 5 do not overlap with each other as in the conventional case, the operation sensitivity when the step plate 7 is stepped on is good (light), and the closing operation of the entrance 2 by the plate-like door 5 is reasonably possible. .

[0016]

FIG. 1 shows a preferred embodiment of the trap of the present invention.
