Double-entrance rat trap made of polyvinyl chloride pipe

Abstract

To address such a problem that rats are often caught in wire mesh cage traps, but effectiveness of the traps is halved because the wire mesh is see-through, making it too bright inside, creating a dead end where the rat cannot escape when attacked, and an entrance is on one side, so rats coming from the opposite direction cannot get in, and to provide a rat trap with entrances on both sides using a polyvinyl chloride pipe that is familiar to rats, because rats often enter and exit PVC pipes in drainage ditches.MEANS FOR SOLVING THE PROBLEM: Both ends of a horizontally placed vinyl chloride pipe are cut vertically to provide left / right rat entry holes, and trap sliding grooves are provided inside the pipe at a place slightly separated therefrom by diagonally opening toward a ceiling. After that, left / right trap doors that go up and down in the grooves are just made to complete the skeleton, and since an existing pipe is used, the process is short. The trap is easy to use, the left / right trap doors are lifted in an inverse-V-shape up to the space above the pipe, both the doors are stretched with a string to hold them stationarily, and a bait stick is hung on the string and suspended in the pipe. When a rat enters from either of the entry holds and bites the bait, a razor blade attached to the stick cuts the string, causing both left and right doors to fall simultaneously, trapping the rat inside the pipe.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a rat trap made of PVC pipes, which incorporates structures and functions that correspond to the habits of rats. [Background technology]

[0002] Trapping mice at home is generally done using a wire mesh cage with bait suspended in a container. Other methods include sticky paper and strong spring clamps, but these are rarely used because the area around the trap becomes dirty with mouse hair and blood, making it a gruesome sight. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5315471: Technology for placing an adhesive sheet inside a cylinder [Patent Document 2] Published in 2007-6161076 Technology for placing a seesaw inside a long, narrow cage Summary of the Invention [Problem to be solved by the invention]

[0004] The wire cage-type mouse traps currently used in ordinary homes have the following problems: 1. Mice have a habit of not wanting to be seen, so wire mesh see-through traps are only half as effective. 2 Rats have the habit of searching for food by moving forward again and again, so a trap with only one entrance is half as effective. 3 Rats have a habit of preferring dimly lit places, so wire mesh traps that let in sunlight are half as effective. 4 Mice have a habit of liking small spaces, so a wide wire mesh cage will be half as effective. 5 The trap extends far outside the catcher, so it cannot be used in narrow spaces such as behind furniture. 6 The caught mouse is clearly visible through the wire mesh, so faint-hearted people may hesitate to use the trap. 7 Metal materials and processed metal products are expensive, so even those who want to buy several to exterminate them all at once will only need to buy one.

[0005] This invention consists of the following three means, and we will explain how each means solved each of the above problems.

[0006] Method 1: Use PVC pipe. Create a trap out of PVC pipe that takes into account rat habits. Having previously seen rats entering and exiting drainage pipes in stone walls, I thought rats and pipes would be a good match. PVC pipe is a readily available, inexpensive product, and solves problem 7, "Buy a few and exterminate them all at once." The inside of the PVC pipe is also isolated from the outside, solving problem 1, "Don't want to show yourself," problem 3, "Dimly lit place," and problem 6, "Don't want to see the captured rat." Furthermore, PVC pipe comes in a variety of sizes, so I used pipes of the appropriate size to create a trap of the perfect width for each rat species, from house mice with a body length of about 10 cm to brown rats with a body length of over 20 cm, solving problem 4, "Narrow, just above the rat's height," and problem 5, "Installed in a narrow space."

[0007] Method 2: Use both ends as entry points. As soon as I got the pipe, the idea of ​​using both ends as entry points came to me easily. Since both ends of the pipe are cut vertically, I could simply use them as entry points. The lid (trap door) that is attached to the pipe, which is an essential entry point for mice, is made roughly square, and rather than being attached to the pipe using the "door hinge" method used in wire cages, this invention uses a "sluice gate groove method." The advantage of a sluice gate trap is that the lid is placed in the trap grooves on the left and right sides of the pipe, which can withstand mice's strong attempts to pry it open. By using the above method of creating entrances on both ends, the trap becomes a tunnel that mice can pass through, solving problem 2, "mice only move forward."

[0008] Method 3: Close the traps simultaneously. Create a system that closes both the left and right trap doors simultaneously when a rat enters. If they are not closed simultaneously, the rat will escape. To prevent this, the openings of the left and right trap grooves mentioned above are opened diagonally, like the letter "V" on the pipe. Both doors, which are inserted into the diagonal grooves, are lifted in the space above the pipe in an "V" shape, and both doors are held in place by a string. If a rat enters the pipe and cuts the string, both doors will instantly fall simultaneously. [Effects of the Invention]

[0009] The present invention has the following excellent effects: 1´ Open both ends of the pipe to create a path that rats can walk through, as they hate dead ends. 2´ Open both ends of the pipe to make a trap that can accommodate mice moving in either direction. A tunnel made from 3' pipes is used as a trap in a dimly lit area to reduce the sense of discomfort for the rats. 4´ Choose the outer dimensions of the pipe to create a trap for each species, making sure it is just long enough to accommodate the rat's body length to minimize discomfort. This trap is placed diagonally above a 5' pipe, allowing it to be used in tight spaces. The trap is held in place by a 6´ pipe groove, so a normal spring will suffice to attract the trap. Since it is made from 7' pipe, the caught mouse cannot be seen, making it a trap that can be used by even the faint of heart. 8" pipes can be made using commercially available parts with a short process and minimal work, so they can be offered at a low cost.

[Figure 3] Figure 3 is a perspective view showing that the lower part of the pipe has been cut horizontally to make the trap more stable. DETAILED DESCRIPTION OF THE INVENTION

[0011] The first embodiment of the present invention will be described with reference to FIGS.

[0012] The present invention is a rat trap that catches rats 5 by suspending bait 11 inside a PVC pipe 1. For this purpose, a pipe with an inner diameter, length, and hardness appropriate for the species of rat to be trapped is selected.

[0013] Creating a rat entry point 14. Lay the PVC pipe 1 horizontally and cut both ends vertically to create rat entry points 14 on the left and right.

[0014] Create a trap sliding groove 2. When a mouse 5 finds bait 11 hanging from the trap and enters the trap, the trap is closed and it is trapped inside, but this groove is for the trap to move up and down smoothly. The groove opens diagonally on the inside of the pipe, slightly away from the mouse entry opening 14. In other words, the groove starts from a position slightly closer to the center of the pipe than the entry opening and slightly closer to the ceiling of the pipe than the bottom of the pipe, and opens diagonally from here at an acute angle to the entry opening towards the ceiling in the center of the pipe until it breaks through. Create this on both the left and right.

[0015] A roughly square trap door 3 is made to slide up and down the trap sliding groove 2. The door thickness is within the groove dimensions, the door dimensions are equal to or larger than the outer diameter of the pipe, and the bottom shape of the trap door 3 is made similar to the shape of the bottom of the pipe.

[0016] Attach a tension coil spring 7 that strongly pulls the trap door 3 to the bottom of the pipe. This is to pull the trap strongly to the bottom of the pipe so that the trapped rat 5 does not lift the trap and escape. Set this on both sides between the top of the trap door 3 and the outer ceiling of the PVC pipe 1.

[0017] Small thread stopper openings 4 are made on the left and right sides of the trap door 3. A single pulling string 13 is stretched to pull the left and right trap doors 3 together in a V shape and keep both doors high in the space above the pipe, and this is the thread stopper.

[0018] A bait stick 6 is placed on which the bait 11 to be guided is hung. The upper part of the stick is hooked onto the pulling string 13, and the lower part is passed through the conduit 9 and hung down inside the pipe.

[0019] A razor blade 12 is attached to the top of the bait stick 6. It is a sharp blade that cuts the pulling line 13.

[0020] Drop bait 11 onto bait stick 6 and wait for mouse 5.

[0021] The capture of a mouse 5 is explained in Figure 2. The mouse 5 eats the bait 11 and pulls the bait stick 6, which in turn pulls the pulling string 13 downward. The pulling string 13 is then cut by the razor blade 12 on the stick, and the trap door 3, which is attached to the string and suspended high above the pipe, falls, and the left and right doors trap the mouse 5 inside the pipe.

[0022] Claim 2 will be explained with reference to Fig. 2. In claim 2, the bottom of the horizontally placed PVC pipe 1 is horizontally cut and a flat stable base 15 is placed under the pipe. This makes the trap more stable and also makes the path for the rats 5 to walk flat, stabilizing the rats' movement inside the pipe.

[0023] Claim 3 uses iron pipes, hard paper pipes, or hard fiber pipes for the frame of claims 1 and 2, rather than PVC pipes. A trap made of iron, which is harder than PVC, is created, and a trap that cannot be torn apart by the strong teeth of a rat 5 even if the rat is trapped and left there for several days. Hard paper drainage pipes are already in practical use, and some bulletproof vests made of aramid fiber, which is even stronger than iron, are also in practical use. If these can be mass-produced in the future and costs can be reduced, rat traps could be made from these two new materials. [Industrial Applicability]

[0024] Other small pests that cause harm to people's daily lives include palm civets and weasels. The PVC pipes used to trap these include pipes with an outer diameter of up to 50 cm, as well as hardened pipes known as PVC pipes, so this technology can be used to exterminate these small pests as well as mice.
