Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a trap for catching animals such as rats that crawl on the ground.

[Conventional technology]

Conventional trapping devices of this type consist of a cage with an entrance on the side, a door that closes the entrance using a force such as the restoring elasticity of a spring, and a feeding lever inside the cage that locks the door in the open state. Something was warm.

[Problem that the invention attempts to solve]

However, with this trap, if a mouse enters the cage and pulls the bait on the feeding lever,
The problem was that the door would fall off and close the entrance, making it impossible for the mouse's friends and family to enter with their friends, making it impossible to capture a group all at once. Also, the use of rat poison had the disadvantage of causing carcasses to be scattered, resulting in unsanitary conditions.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention consists of a housing with an entrance located at a relatively high position on the side, and an entrance that is supported via a spindle at the entrance of this housing and is rotated and reversed. a balance-shaped walkway for closing the walkway; a stopper that is mounted on the bottom of the casing via a support shaft so as to be able to rise and fall freely and abuts against and locks the inner end edge of the walkway; and a support shaft of the stopper; It consists of a relatively low swingable tread with a free end connected to the inner side and interlocked with it to free the walkway, and the stopper is equipped with a weight, a spring, or a magnet attached to the footboard to allow the walkway to be moved freely. When the abutting force is applied and the footboard is stepped on, the stopper falls down and the corridor is unlocked, allowing the corridor to swing freely.

[Effect]

In this design, the entrance is normally open, allowing animals such as mice to crawl freely on the walkway and enter the cage at any time, and once the animal enters the cage, it is blocked by the walkway that turns and escapes. It is possible to capture a group at once without being able to do so. In other words, when an animal inside the cage tries to escape from the entrance by stepping on a low-level tread and crawling up to a high-level walkway, the tread falls under the animal's own weight, causing the interlocking stopper to fall, causing the walkway to swing. It becomes a flexible scale, and if an animal climbs onto the inner end of the walkway, the walkway will turn over and the entrance will be closed at the outer end, preventing it from escaping.

Furthermore, when an animal steps down from the walkway or treadle to search for another exit, the walkway naturally returns to its horizontal state and the entrance is opened.

〔Example〕

An embodiment of this invention will be described based on the accompanying drawings. As shown in FIGS. 1 to 3, the trapping device of this invention includes a semicylindrical cage 2 formed from wire and having a square-shaped entrance 1 of a required size at a relatively high point on one side. , is attached to both corners of the lower edge of the entrance 1 of this housing 2 via a support shaft 3 at a relatively high position from the bottom surface, and is oscillated in the opposite direction (in the direction of the arrow A in Fig. 5).
Reference) A scale-shaped walkway 4 that closes the entrance 1 and a cage 2
It is attached to a base 13 (details will be described later) on the bottom surface 5 of the walkway 4 via a support shaft 6 so as to be able to rise and fall freely (see arrow direction B in FIG. A stopper 7 with a Z-shaped cross section to be engaged, and a pair of relatively low swingable footboards 8 whose free ends are connected to the inner side of the support shaft 6 of the stopper 7 and work together to free the walkway 4. The stopper 7
The walkway 4 is moved by a weight 10 fixed on the lower board 9.
A force (see arrow direction F in FIG. 3) is applied, and the step board 8 is positioned on both sides of the contact area between the stopper 7 and the walkway 4 (see FIG. 4), and as shown in FIG. For example, if a mouse that has entered the cage 2 steps on the low-positioned tread 8 in an attempt to escape from the entrance 1, the stopper 7
collapses, the lock on the walkway 4 is released, and the walkway 4 becomes a swinging balance, and when the mouse climbs onto the walkway 4 from the tread 8, the walkway 4 turns and reverses, and the entrance 1 is closed on its outer surface. It is something that will make you feel better.

A handle 11 is attached to the center of the top of the housing 2, making it easy to carry. In addition, the housing 2
In this case, entrances 1 may be provided on both opposing sides, and the trap may be placed so that the paired entrances 1 are on the path of the mouse, so that it appears that the mouse can pass through. Although a bait stand 12 is fixed approximately at the center of the bottom surface 5 of the cage 2, this may be omitted and the bait may be placed directly on the bottom surface 5. Furthermore, in the case of a cage having entrances 1 facing each other, a long corridor-like bait stand may be attached so as to connect these entrances 1. Note that this housing 2 can also be substituted by providing an inlet 1 in an empty tin can.

The walkway 4 is formed by an upright base 13 having an L-shaped cross section and forming a part of the casing 2, with an outer plate portion protruding from the casing 2 curved downward and the inside of the support shaft 3 being substantially horizontal. It is swingably supported at the upper end of the plate 14 by a support shaft 3, and the outside part of the support shaft 3 is heavier than the inside part, so that even if the locking by the stopper 7 is released, the outward-hanging state is maintained. can. Engaging protrusions 15 for fixing to the casing 2 are protruded from both end edges of the upright plate 14 of the base 13.

As shown in FIG. 3, the stopper 7 is arranged on an upper plate 1 which is arranged along approximately the same axis and at approximately the same height as the walkway 4.
6, a vertical plate 17 connected to this upper plate 16, and a lower plate 9, which has a Z-shaped cross section, and the bent corner of the upper plate 16 abuts against the inner edge of the walkway 4 so as to support it from below, The lower end corner of the vertical plate 17 is the support shaft 6
It is supported on the base 13 by. In addition, the lower plate 9 is provided with a force that applies the force of contact with the walkway 4.
In addition to the weight 10, the elasticity of a spring or the attraction force of a magnet can also be used.

As shown in FIGS. 3 and 4, the treadboard 8 has a substantially L-shaped cross section with a horizontal board 19 and an upright board 20 connected to each other.
The bent corner is swingably attached to the upright plate 14 of the base 13 by a support shaft 18 so that the height is 2. They are connected in a hanging manner in the middle. The upright board 20 serves as a protective wall to prevent mice from jumping out from the side of the walkway 4 or running away through the cage without stepping on the walkway 4.

This step board 8 is designed so that, for example, a mouse can step onto the elevated walkway 4 that leads to the entrance 1. As shown in FIG. It swings down due to its own weight, and in conjunction with this, the stopper 7 falls inward and is released from the lock, making the walkway 4 in a swinging balance state. When the mouse crawls onto the end of the walkway 4, this The walkway 4 is inverted and stands up, and the entrance 1 is now blocked.

Furthermore, when the mouse gives up and descends onto the bottom surface 5, the stopper 7 is restored to its original position by the weight 10, and the walkway 4 is also naturally restored to its original position, and the entrance 1 becomes open.

The trapping device of the present invention can be used to capture not only rats but also animals that crawl on the ground, such as stray dogs, cats, and rabbits.

〔effect〕

As mentioned above, the trap according to this invention usually has an open entrance, allowing animals such as mice to freely enter the cage at any time, and once the animal enters the cage, it is blocked by a reversing walkway. It has the effect of being able to capture a group all at once, without being able to escape.
