Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to the construction of a simple rat trap.

[Conventional technology]

Conventional rat traps include those that have a bait hook suspended in a wire mesh cage that is linked to an entry door, and those that trap rats using spring action.
In addition, Utility Model No. 57-6156 is known as a device that uses the habits of rats to capture them without using bait.

[The problem that the idea attempts to solve]

The above-mentioned Utility Model Publication No. 57-6156 does not use bait, but instead places the bait in a rat passage and waits for the rats to enter before catching them, but the capture rate is low because only rats that enter accidentally are caught. The purpose of the present invention is to prepare bait inside a net container and take advantage of the conciliatory behavior of rats to actively capture a large number of rats while the bait is available.

[Means to solve the problem]

In order to solve the above problems, the present invention constructs a mesh container 1 by forming appropriate holes in the front and rear side walls 3, 3', the floor wall 13, and the peripheral wall 4 using wire mesh material, and 3 is provided with a bag-shaped guide body 7 whose bottom is open and slopes upward at the rear, a stopper member 9 is formed at the bottom end of the guide body 7, and the guide body 7 is rotatable by a support shaft 11. To provide a mouse trap characterized in that a weight 10 is attached to the other side of the formed gangboard 6, and an entry passageway opening 2 is formed by bringing the gangboard 6 into contact with a stopper material 9 at the lower end of the open bottom. It's what I did.

[Effect]

A rat that finds food such as meat inside the mesh container moves around the container by chance, finds an entry passage, and enters the bag-shaped guide body with an open bottom and a slope. When the rat enters and steps onto the gangplank, it falls due to the rat's weight, is released from the guide body, and reaches the bait. When removed from the spanning plate, the spanning plate is brought back into contact with the stopper of the guide body by the weight using the support shaft as a fulcrum. If a large amount of bait is placed in the container, the rats will move around the container one after another and enter the bag-shaped guide body and be captured, resulting in a high capture rate. Since the gangplank is in contact with the stopper, its movement is always constant even when it is repeatedly operated.

Next, one embodiment of the present invention will be described based on the drawings. FIG. 1 shows a partially cutaway perspective view of an embodiment of the present invention, in which a mesh container 1 is constructed in the shape of a basket by front and rear side walls 3, 3', a floor wall 13, and a peripheral wall 4. A wire mesh material with appropriate holes is used. Reference numeral 2 designates an entry passage opening, and a bag-shaped guide body 7 with an open bottom and an inclined side is provided, and the lower end of the bottom is formed of a frame material. A stopper member 9 is fixed at a somewhat higher position inside the frame member 8, and the base of the stopper member 9 extends along the frame member 8 to the lower end of the side wall 3 to form a bearing 12. .

Reference numeral 6 designates a span plate whose front end has a shape substantially matching the inner shape of the frame member 8 of the guide body 7, and is sized to come into contact with the stopper member 9. A support shaft 11 is fixed to both sides of the base of the spanning board 6, and an extension part is provided further from the support shaft 11 in parallel with the floor wall 13.
A weight 10 is fixed to the extension part, and the weight is set to be heavier than the own weight of the front end of the connecting plate 6, so that the supporting shaft 11 normally functions to return the connecting plate 6 to the stopper member 9 using the bearing tool 12 as a fulcrum. It is set to such an extent that it becomes quick. If it is too heavy, there is an inconvenience that even if rats are guided to enter the gangplank 6, they will not easily fall down.

Reference numeral 5 designates an opening/closing window, which opens and closes using its lower part as a fulcrum, and has a locking tool at its upper part. 14 is a bait hook for attaching bait to attract rats.

To explain the action here, in Figure 2, the mouse attracted by the bait goes around the trap,
A rat with a tendency to invade enters the entry passageway 2 , the gangplank 6 falls F due to its weight, the lower part of the guide body 7 opens, and the rat heads toward the food. At this time, weight 1
0, the gangplate rises f and quickly returns to abut against the stopper material. Therefore, even if a rat hits the back side of the gangplank 6, the gangplank 6 will only be brought into close contact with the stopper material.

〔effect〕

Therefore, according to the structure of the present invention, if the bait that attracts rats is properly attached to a bait hook or placed in a large number of baits, the rodent's habit of attracting rats will cause them to intrude one after another. It was possible to capture it by entering the road entrance. Additionally, in the past, spring materials or complicated structures were difficult to install or caused failures, but with the present invention, there are no parts to adjust or operate, and all you have to do is place it in the desired location. There are other effects.
