Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a trap for animals such as rats, and more specifically, a device for automatically and continuously trapping small animals, particularly rats, etc. This invention relates to a device for trapping animals such as rats.

[Conventional technology]

Hitherto, various configurations of traps for animals such as mice have been provided.
``Automatic mouse trap using balance pedal'' disclosed in Publication No. 1 is known.

That is, as shown in FIG. 5, the trap consists of a trap case 11 which has a mouse entry port 12a on the front side and a guide case 12 with a bait placement section 23 on the rear side and an open upper side. A horizontal plate 16 is provided on the top surface of the guiding case 12 and a horizontal plate 16 is provided on a part of the bottom of the guide case 12 to close the front opening and the rear opening, respectively, and a tread plate (balanced board) whose other end moves up and down with each end as a fulcrum. It has a configuration including a pedal (14) and a treadle 14a.

The trap allows the mouse to pass through the mouse entrance 12a of the guiding case 12 through the footboard 14a and the horizontal plate 16.
When the mouse reaches the top of the footboard 14, the footboard 14 loses its balance due to the mouse's own weight and tilts downward, and the front side of the footboard 14a is moved upward to close the mouse entrance 12a and the mouse slides into the trapping case ll. It acts like a trap. According to this configuration, since the time for the mouse to pass through the guiding case 12 where the bait is placed is short, the unique odor of the captured mouse is less likely to remain in the case 12, and it is possible to continuously capture mice. It has the advantage of being

[Problem that the invention seeks to solve]

However, in the above-mentioned trap for animals such as mice, the moment a mouse or the like that has entered through the entrance 12a touches the tread plate 14, which is made up of a balance pedal, via the tread plate 14 and the horizontal plate 16, the tread plate 14 loses its balance. Since it is tilted downward, there is a risk that mice, etc. will fall down instantaneously and remain on the horizontal plate 16 without falling into the capture case 11. Therefore, it will not be possible to continuously capture animals such as mice. There are problems etc.

By the way, there is also a trap that solves the above problems and can continuously capture small animals such as mice, with a different configuration from the one described above (see Japanese Patent Laid-Open No. 83241/1983).
However, this trap has a complicated structure, and it takes a long time to return to the initial state, resulting in a problem in quick response.

The present invention has been devised in response to the above-mentioned problems, and its purpose is to provide a trap for animals such as mice, which has a simple structure and can continuously capture animals such as mice. Our goal is to provide the following.

Means for Solving Problems] The device for trapping animals such as mice of the present invention as a means for achieving the above object has an animal entry port on the front side and an opening on the bottom side. A guide case is provided on the upper side of the capture case with an open top, and a treadle is pivotally supported in the opening of the guide case in a seesaw shape that moves up and down in the front and back direction of the guide case, and the treadle is mounted in a part of the opening. A tread plate holder is provided to hold the tread in a horizontal state, and a magnetic adhesive part is provided on the tread plate and the tread plate holder to magnetically bond the two using a permanent magnet or an electromagnet, so that the downward movement point of the tread plate is set as the fulcrum of the tread plate. When the animal reaches the downward movement point of the tread, the animal's own weight and the magnetic force of the magnetic adhesive part are When the balance between the animal and the animal is lost, the rear side of the treadle rotates downward around the support shaft of the treadle, and the animal falls into the trapping case, after which the treadle automatically returns to a horizontal position. It is made up of the following configuration.

In the above configuration, the treadle is usually made of Tji 11 lightweight material with a smooth surface, and the automatic return of the treadle to a horizontal state is achieved by a stopper that prevents upward movement of the treadle in a fan angle range of 50 to 75 degrees. This is done by the collision reaction force of the treadle and the weight of the treadle, and the magnetic adhesive part is movable along the front and back direction of the guide case.

[Effect]

Based on the above configuration (the device for trapping animals such as mice of the present invention is first attached to the step board using magnetic adhesive so as to hold it in a horizontal state), the step board is installed in an attic or other place where there are mice, etc. If the mouse or the like enters the guide case through the animal entrance in an attempt to eat the lure inside the guide case, it will further enter the back of the case and pass through the fulcrum of the treadle, causing the mouse to enter the treadle. When the downward movement point is reached, the balance between the animal's own weight and the magnetic force is disrupted, and the back side of the treadle rotates downward, causing the animal to fall into the trapping case, and after falling, the treadle is It acts to automatically return the rotation to the initial horizontal state.

〔Example〕

Hereinafter, embodiments embodying the present invention will be described with reference to the drawings.

1 to 3 show embodiments of the present invention, FIG. 1 is a perspective view, FIG. 2 is a side sectional view, FIG. 3 is a front sectional view, and FIG. It is an enlarged view of the part. Note that parts corresponding to those shown in FIG. 5 described above are given the same reference numerals.

This embodiment is a mouse trap in which the animal to be captured is a mouse, and roughly divided into a trap case 11 and a guide case 12, similar to the conventional example.

The capture case 11 is constructed as a synthetic resin case with dimensions of, for example, approximately 35 mm in depth, 25 mm in width, and 23 mm in height. The opening 13a is provided with a footboard 14 pivotally supported by an opening 12a of the guiding case 12, which will be described later.
By F! It's covered. A liquid 11a such as oil or water is placed inside the case 11 to a depth of 10 cm to 12 cm. J
It is constructed so that it can be stored to a certain depth.

Here, as the liquid, it is preferable to use oil or the like with low buoyancy in order to cause the mouse to drown in a short time, and as the kernel oil, residual oil such as tempura oil may be used.

Note that it is usually preferable not to mix poisonous substances into the liquid, and a thick old cloth 20 on which rats can easily climb is provided on the front side of the trapping case 11.

The guide case 12 has a depth of 30 cm and a width of 14 cm, for example.
It is constructed as a case made of synthetic resin and has a height of about 12 cm, and has a mouse entry port 12a on the front side, an opening 12b on the bottom side, and a footboard 14 is pivotally supported in the opening 12b. The configuration is as follows. The footboard 14 is made of a thin, lightweight material with a smooth surface and is formed into a trapezoidal plate (it may be rectangular or the like) narrowed at both ends on the rear side. As a fulcrum, it can move up and down like a seesaw along the front and back direction of the case 12. Here, the step board 14 is made of a material as light as possible, such as a thin styrene foam plate coated with aluminum foil, and in this embodiment, a plate material weighing about 20 g is used. This is to make the footboard 14 operate more sensitively (taking into consideration that the smaller the ratio between the weight of the footboard and the weight of the mouse, the more sensitively the footboard operates). However, this does not preclude the use of something with a certain amount of weight, such as an aluminum plate. Also, the opening 12b or the opening 13a
A footboard support 16 for holding the footboard 14 in a horizontal state is installed between both walls 17.17. The depth of the footboard support 16 is normally set to a size that covers the opening 12b between the positions closer to the support shaft 15 than the mouse entry port 12a.

Incidentally, the step board support 16 may be replaced with the top plate 13 of the capture case 11. In this case, the top plate 1
3 forms the footboard support 16. In addition, a permanent magnet 18 is attached to the rat entry port 12a of the footboard holder 16, and a magnetic metal piece 19 is attached to the corresponding surface of the footboard 14 corresponding to the permanent magnet 18, and a magnetic metal piece 19 is attached to the corresponding surface of the footboard 14 to attach the footboard 14 to the footboard holder. 16
It is formed so that it can be held horizontally by magnetic adhesion.

As for the magnetic adhesive force between the permanent magnet 18 and the magnetic metal piece 19, in this embodiment, a magnet that can withstand a load of 7 g is used. This is due to the fact that the target mice were ``hatsuka mice,'' which are light in weight. Therefore, when the mouse M enters the position of the downward movement point a of the footboard 14,
In other words, when a load of 7 g or more is applied to the fulcrum of the footboard 14 at a position a spaced apart toward the back of the case 12, the magnetic adhesion is overcome and the magnetic adhesion is released. In addition, the magnetic adhesive parts 19 attached to the tread plate 14 and the tread plate holder 16 are configured to be movable through slide holes (see FIG. 4) along the front-rear direction of the induction case. If the target is a light mouse, move the magnetic adhesive part to the left in Figure 2, and if the target is a heavy mouse, move it to the right in the figure to trap the mouse as far as possible into the case 12. The magnetic adhesion is released just before the bait 21 is bitten. This prevents the footboard 14 from returning to the horizontal position even if the mouse backs up.
．． If the tread plate 15 is moved to the right of the center of the tread plate 14, it will be difficult for the tread plate 14 to automatically return.
It is preferable to adopt a structure that strengthens the return force, such as increasing the weight on the right side of 4.Furthermore, it is preferable to adopt a configuration that strengthens the return force, such as increasing the weight on the right side of 4.
14 is released from the magnetic adhesion and rotates in the direction of arrow C around the support shaft 15.15 as shown by the imaginary line in Figure 2 due to the mouse's own weight, but its rotation range (vertical movement range) The stopper 22.
22 protrudes from both walls 17.17, and the stopper 22.22 is provided so that its position can be adjusted arbitrarily, thereby making it possible to change the rotation angle range of the footboard 14. ing. Further, a removable bait placement section 24 made of a wire mesh is provided at the bottom of the back side plate 23 of the mouse guiding case 12, and the bait 21 can be replaced by removing the bait placement section 24. That's how it is.

Further, the guide case 12 is connected to the opening 11a of the capture case 11.
It is formed so as to be removably fitted into the top plate 13, and is placed on the top plate 13 by four protruding pieces 26, 26, . . . . Therefore, the capture case 11 and the guide case 12 are made completely separate, and a trash can or the like in each household is used as the capture case 11, and the guide case 12 is placed on top of the box as necessary. It is now available for use. Next, based on the above configuration,
The operation of this embodiment will be explained.

That is, the mouse M is attracted by the smell of the bait 21 and climbs the old cloth 20 to enter the mouse entry hole 1 into the guiding case 12.
It invades from 2a. Then, it moves straight aiming at the lure 21, but when it passes the fulcrum of the footboard 14 and reaches the downward movement point a in FIG. The mouse M suddenly turns in the direction, falls into the trapping case 11 without reaching the bait 21, and drowns in the oil 11a stored in the trapping case 11. Then, the treadle 14 comes into contact with the stopper 22.22,
The reaction and the weight of the footboard 14 cause it to rotate in the opposite direction to the direction of arrow C, and together with the magnetic force of the magnet 18, it returns to the horizontal state. This again causes the so-called trap to become a state.

Incidentally, in the above-described embodiment, the treadle and the treadle holder are bonded together by magnetic adhesive using permanent magnets, and the point for downward movement of the treadle is located on the back side of the guiding case. However, the present invention is not limited to this, but it is also possible to use an electromagnet rather than a permanent magnet as a magnet, for example, by changing the t-current to change the strength of the magnetic force, or by installing a sensor that detects the weight of an invading mouse at the entrance of the mouse. Set it up,
It is also possible to have a configuration in which the magnetic force is changed in accordance with the body weight in accordance with the body weight, and in which the downward movement point of the footboard is always located at a certain position on the back side of the guiding case.
The structure may be such that the position of the magnetic adhesive part or the fulcrum is moved, or the magnet is replaced.

In addition, in this embodiment, a magnet is attached to the footboard holder,
Although the configuration has been described in which a magnetic metal piece is attached to the treadle, the configuration may be reversed. In addition, if the entire treadle is made of magnetic material, there is no need to add another piece of magnetic material, and all or part of the surface of the treadboard corresponding to the treadle plate (to prevent movement of the magnetic adhesive part of the treadle plate) The magnetic powder may be arranged in a line (eg, in a line along the front-rear direction of the case).

Furthermore, in this embodiment, the fulcrum (support shaft) of the treadle is located at the center of the treadle. The fulcrum of the guide case is formed so as to be located on the entrance side of the guide case, and the step plate holder is connected to the case with a spring or the like.
In addition, the tread plate and the tread holder are magnetically bonded, and the weight of the mouse overcomes the spring force and magnetic force, causing the tread plate to rotate downward about the support shaft, and after the mouse falls, the spring force returns to the initial position. It is also possible to adopt a configuration in which the state is restored.

Furthermore, although the description has been made using a mouse as the object to be captured in this embodiment, the trap of the present invention can of course be used to capture not only mice but also other animals, especially small animals. If you do not store liquids such as water or water, you can trap the animal live, or if you set it in a field or field, you can bury the trapping case part underground. Instead of being box-shaped, it may be a bag or the like (in this case, the structure is such that it is placed under the top plate).

Furthermore, although the trap of this embodiment has a structure in which the animal entrance is provided in only one direction, for example, the trap of this embodiment may be arranged radially in three directions and combined into one piece. (This is to take into consideration that the shape and size may vary depending on the animal to be captured).

Incidentally, it is clear that the present invention is not limited to the above-described embodiments, but includes modifications that can be made without departing from the gist of the present invention.

〔Effect of the invention〕

As is clear from the above description, according to the mouse and other animal trap of the present invention, the treadle is attached to the treadle holder by magnetic force, and the downward movement point of the treadle is positioned on the back side of the guide case from the fulcrum of the treadle. In this way, even when an invading animal such as a mouse passes through the fulcrum position of the tread, the tread does not immediately turn downward, and when it reaches the point for downward movement, the back side of the tread instantly rotates. Since it rotates downward using the support shaft as a fulcrum, it is possible to reliably fall and capture animals such as mice into the trapping case, and the treadle automatically moves after capturing animals such as mice. Since the trap returns to its original state, it has the effect of being able to continuously capture animals such as mice.

Furthermore, according to the present invention, the configuration is such that animals such as mice can be captured using the guide case, the capture case, and the treadle having the magnetic adhesive part, so the structure is simple and the structure is simple, and moreover, the structure is simple, and the structure is simple. This has the effect of providing a trap for animals such as mice that can be caught quickly.
