Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pest control method for tatami mats , which can easily and surely kill pests lurking in tatami mats. 2. Description of the Related Art Traditional tatami mats include tatami mats woven from rush sacks using hemp and cotton yarns as warp yarns, tatami mats made of rice straw as raw materials, and tatami floors and mats. Tatami mats that decorate the edges of the tatami mats. The tatami mats are covered with tatami mats on the surface of the tatami mat floor and sewn together with the tatami mats to complete the tatami mat. [0003] Although the above-mentioned traditional tatami mats are sufficiently controlled for quality, there has been a problem in that the tatami mats tend to be a hotbed of pests such as mites due to long-term use. In addition, since maintenance such as periodically drying the tatami mats is less frequently performed, pests are more likely to parasitize. In order to solve such a problem, a tatami mat having an insect repellent function has been proposed. For example, as a tatami mat floor, a styrofoam board, a plywood board made of wood chips, or a board made of plastic or urethane having a predetermined hardness is adopted, and a tatami mat that is less likely to be a hotbed of insect pests by selectively laminating and using them. Also, there is a tatami mat having an insect repellent effect by interposing an insect repellent sheet coated or impregnated with a predetermined agent between the tatami mat surface and the tatami mat floor. Hereinafter, these tatami mats will be referred to as hybrid tatami mats with traditional tatami mats. [0005] Tatami suppliers are also providing various maintenance services. For example, one or more tatami mats are housed in a sealed case, and an insecticide or hot air is sent into the case. In order to exterminate the pests, or apply a board with a predetermined size and multiple vent holes to the surface of the tatami mat laid in the room, and send insecticide or hot air from the vent holes of the board to remove the pests. Some services are designed to get rid of them. [0006] However, in the conventional hybrid tatami, even if an insect repellent sheet is interposed, the efficacy of the insect repellent sheet does not continue for several decades, and the insect repellent effect gradually increases. However, there is a problem that maintenance needs to be performed after several years. Even if a material that is unlikely to be a hotbed for insects is used for the tatami mat, the tatami mat remains the same, so that the tatami mats are parasitized by the pests, and ultimately no significant effect can be expected. [0007] Regarding maintenance, conventional maintenance services for pest control require that all tatami mats be rolled up in a sealed case, or a board be put on the surface of all tatami mats. Therefore, when performing pest control on tatami mats on which furniture and the like are arranged, the furniture and the like had to be moved, which was troublesome. That is, conventionally, in order to perform pest control on the tatami mats in the whole room, the whole tatami mats have to be turned up and furniture has to be moved, which has not been easy. The present invention has been made to solve the above-mentioned problem, and it is a pest control method for tatami mats that can easily and surely kill pests lurking in tatami mats without turning over the tatami mats or moving furniture. The aim is to provide a method. [0009] To achieve the above object, according to an aspect of tatami method of pest control of the present invention, even small without the Tatamiyuka a two-layer structure, intermediate or of the layer structure a groove is formed in the upper surface or lower surface of the layer positioned in the lower layer, all the layers together with sewing integrally, an opening is provided for feeding insecticides or hot air into communication groove and with the one side surface of the tatami floor mats
The room so that the opening faces the tatami mat in the center.
Place the tatami in the center and adjacent to the tatami to eliminate pests
Sometimes, only the tatami mat in the center of the room is turned up,
Send insecticide or hot air through the opening on the side of the tatami mat,
In addition, it appears on the side of the adjacent tatami mat by turning the central tatami mat
The insecticide or hot air was sent from the opening . In this way, the pests lurking in tatami, it is possible to easily and reliably insecticidal without or move furniture or flip through the entire mat. [0010] tatami method of pest control of the embodiment of the present invention is a two-layer structure even less without the Tatamiyuka, grooves on the upper surface or lower surface of the intermediate or positioned beneath the layer of the layer structure Forming a plurality of tatami mats having an opening for feeding insecticide or hot air through one side of the tatami floor and communicating with the groove, and a central part of the room, Open
Adjacent to the central tatami so that the mouth faces the central tatami
When performing pest control, place in the center of the room
Turn the tatami mat only, and from the opening on the side of the tatami mat in the center
Send insecticide or hot air, and turn over the central tatami mat.
And insecticide or heat from the opening that appears on the side of the adjacent tatami mat
The tatami is blown in through the grooves and seams that communicate with each other.
Exterminate pests in tatami by leaking insecticide or hot air to the body
It is those that. According to the above SL, each layer in Tatamiyuka, for example styrofoam board, wood chips plywood board or a predetermined hardness may be used boards made of plastic or urethane, and the raw material of conventional rice straw May be used. When a conventional board made of rice straw is used as one layer of the layer structure, the above-mentioned styrene foam board, wood chip chip plywood board, or It is desirable to use a board made of plastic or urethane having a predetermined hardness. The reason is that the pest control method of the tatami of the present invention
The tatami mat used for forming a tatami floor has an opening on one side and a groove communicating with the opening on the upper or lower surface of a layer located in the middle or lower layer of the layer structure constituting the tatami floor. This is because it is difficult to form with a board made of styrene. Of course, when the groove having a concave cross section that forms the predetermined passage is buried in the upper or lower surface of the board made of rice straw, the configuration of the tatami used for the pest control method of the tatami of the present invention can be realized. However, it is disadvantageous because troubles such as labor and cost are caused at the same time. Now, each layer of the tatami floor having the layer structure is sewn together to be integrated. The holes are naturally formed by passing the needle through each layer when sewing together, so the insecticide or hot air injected from the opening formed on the side of the tatami floor goes into the inside of the tatami through the groove. Over this time, the insecticide or hot air passing through the groove leaks from the hole through which the needle passes when the above-mentioned layers are sewn together to integrate them. That is, although this needle hole is a very small hole, a plurality of holes are formed, and each layer of the tatami floor is not bonded with, for example, an adhesive. First, it overflows from the groove, and goes from the hole through the needle through the surface of each layer to the upper part (to the front of the tatami mat) or the lower part of the tatami mat, so that an appropriate amount is evenly spread to every corner of the tatami mat. It becomes. By doing so, it is not necessary to store the tatami in a case in order to keep the tatami in a sealed state, and the tatami table does not change at all in the room. Without damaging, the pests of the whole tatami can be more reliably and easily exterminated. [0018] Contact Keru tatami in the above, to form two openings at positions which are symmetrical across the center of one long side of one side surface, each of these openings, facing the one of the long sides Two main grooves are formed linearly toward the other long side, and a plurality of branch grooves are formed in parallel with the short sides in a direction perpendicular to and communicating with the two main grooves. It may have a lid for closing one of the two openings. In this manner, when the tatami is laid, even if two openings are both exposed depending on the laying state of the tatami, one of the openings is closed with the lid and the other opening is opened. An insecticide or hot air can be injected, and by having the main groove and the branch groove, the insecticide or hot air can be spread over the entire surface of the tatami mat. Further, the following operation and effect can be obtained by providing two openings at positions symmetrical with respect to the center of one long side of one side surface. In the case of a tatami mat having a normal size, a tatami mat laying method is determined according to the size (number of tatami mats) of the room. In other words, when the normal tatami mat has the normal arrangement structure, the side of the long side is directly adjacent to the side of the central tatami, or half of the two tatami mats across the center of the long side. . Accordingly, the present invention is applied to the method for controlling pests of tatami mats according to the present invention .
If two main grooves are formed linearly from a position symmetrical with respect to the center on the side surface (long side) toward the other long side opposite to one long side like a tatami mat, Even if not all of the tatami mats are turned up, if the tatami mats are partially turned up, one or both openings of the tatami mats and the adjacent tatami mats are always exposed. An agent or hot air can be injected. [0022] In the pest control method of the present invention described above,
Tatami used, and the central portion of the room, the opening of the central portion tatami
The tatami mat is located at a position adjacent to the central tatami mat so as to face the tatami mat . By arranging as described above, the insecticide or hot air can be injected into all the tatami mats adjacent to the tatami mat only by turning over the tatami mat at the center. [0024] Then, when performing the pests disinfection, turning only tatami central portion of the room, fed insecticide or hot air from the opening of the mat side of the central portion, also, a tatami central portion It included free feed insecticide or hot air from the opening appearing on the side surface of the adjacent mat by turning. In this way, the injected insecticide or hot air can reach all corners of the tatami through the channels, and then sewn together to integrate the layers of the tatami floor as described above. It leaks out from the needle hole, and the pests can be eliminated reliably and easily. Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a method for controlling pests of a tatami mat according to the present invention.
That is a diagram showing the tatami. FIG. 2 shows a method for controlling pests of a tatami mat according to the present invention.
It is a figure which shows the principal part of the tatami mat used for a law . FIG. 3 shows the present invention.
The method of pest extermination is a diagram illustrating a situation to implement. Tatami 1 used in the pest control method of the tatami of the present invention
Is composed of a tatami table 2, a tatami edge 3, and a tatami floor 4. The tatami floor 4 has , for example, a three-layer structure in this embodiment. The insulation board 4A and a styrofoam board 4 made of, for example, styrofoam under the insulation board 4A.
B, and an insulation board 4C is disposed below the styrene board 4B. As shown in detail in FIG. 2, the styrene board 4B has an opening 4Ba formed on one side surface. In this embodiment, for example, a groove R communicating with the opening 4Ba is formed on the upper surface.
Is formed. The groove R is symmetrical with respect to the center of one long side of the side surface of the tatami floor 4, for example, 1/4 of the length.
, Two openings 4Ba, 4Ba are formed, and two main grooves Ra are linearly formed from these openings 4Ba, 4Ba toward the other long side opposite to one long side, respectively.
Further, for example, three branch grooves Rb are formed to be orthogonal to and communicate with the two main grooves Ra and parallel to the short side direction. In this embodiment, the main groove Ra is completed on the way from the opening 4Ba to the other long side, and the branch groove Rb is completed at both ends. Therefore, as will be described later, surplus insecticide for injecting pests, for example, in this embodiment, which is injected from one opening 4Ba and circulates through the branch groove Rb, passes through the other main groove Ra, and the other opening 4Ba. 4B, the lid 4Bb described later is fitted into the opening 4Ba, as shown in FIG. 1, or the opening 4Ba is closed by the adjacent tatami 1 as shown in FIG. Therefore, the insecticide leaks from the groove R. Here , the tatami floor 1 is formed by laminating an insulation board 4A, a styrene board 4B, and an insulation board 4C and sewing them together to form a tatami floor 4.
At this time, insulation board 4
A, a needle hole P that penetrates the front and rear surfaces of the styrene board 4B and the insulation board 4C and through which the needle passes when sewing is formed. In the present embodiment, for example, the groove R (the main groove Ra and the branch groove Rb) and the needle hole P are configured not to overlap with each other. The reason is that, as described later, the opening 4Ba
When the groove R and the needle hole P overlap each other when the insecticide is injected from the container, the insecticide leaking from the groove R immediately flows from the needle hole P close to the opening 4Ba into which the insecticide is injected. This is because there is a possibility that the insecticide does not spread over the entire groove R. Therefore, by preventing the needle hole P and the groove R from overlapping as in the present embodiment, the insecticide spreads to every corner of the tatami mat 1 and the pest control ability is improved. In this embodiment, when the tatami mats 1 are arranged in six tatami mats as shown in FIG. 3 described later, both the central tatami mat 1A and the central tatami mat 1A are turned over to expose both the openings 4Ba and 4Ba. The lid 4Bb is fitted on one side of the tatami mat 1. Of course, one opening 4B of all 6 tatami mats 1
The cover 4Bb may be fitted into a (the one not exposed). The tatami mat 1 having the above structure is arranged as shown in FIG. 3 in a room of, for example, 6 tatami mats. That is, in general, the tatami mats 1 are arranged as shown in FIG. 3 between the 6 tatami mats, but at this time, the tatami mats 1 except for the central tatami mat 1 (hereinafter referred to as tatami mat 1A in FIG. Tatami 1 and adjacent Tatami 1
The opening 4Ba is directed toward the center. In this 6-tatami room, there is usually no large, immovable furniture such as a chest at the center of the room, and the chest is often placed at the end of the room. Therefore, the tatami 1A at the center can be easily turned at any time, and conversely, the tatami 1A at the end of the room can be easily turned.
Can not be turned without moving furniture etc. That is, the following effects can be obtained by laying the tatami mat 1 in the room with the opening 4Ba facing the center. That is, when the normal tatami mat 1 is arranged, the long side or the short side of two tatami mats are adjacent to each other in half with respect to the center of the long side of the tatami mat 1. Therefore, when the tatami 1 is arranged as described above and the pest control method is carried out, the tatami 1A at the center is turned up, so that the tatami 1 is surrounded by the tatami 1A at the center in FIG. At least one opening 2Ba of all remaining tatami 1 is exposed, an insecticide can be injected from here, and as long as the tatami 1A of the central part is turned up, the remaining five tatami mats 1 can be obtained. There is no need to move furniture and turn it up. In addition, by doing so, the tatami 1 in which one of the two openings 4Ba, 4Ba is exposed by turning the tatami 1A at the center portion is omitted and the cost is reduced by omitting the lid 4Bb. Can also be reduced. That is, for example, in this embodiment shown in FIG.
The lid 4Bb only needs to be two, the central tatami 1A and the tatami 1 where the entire side of the long side is adjacent to each other, compared to providing the lid 4Bb at one opening 4Ba of all the tatami 1. Cost is reduced. Then, the encircled opening 4B shown in FIG.
a, when the insecticide is injected in units of one tatami mat by using, for example, a compressor, the injected insecticide branches off from the main groove Ra and passes through the other main groove Ra or the branch groove Rb to every corner of the tatami 1 Since the insulation board 4A and the styrene board 4B are not adhered to each other, the insecticide leaks from the groove R and leaks from the needle hole P to the tatami mat 2, and the styrene board 4B and the insulation board 4C also Since the insecticide does not adhere, the insecticide leaks out from the groove R and leaks out from the needle hole P to the insulation board 4C, so that the insecticide can be spread over the entire tatami mat 1, and the insect pest can be reliably and easily formed. Can be eliminated. The central tatami 1A is in a rolled-up state, and only one tatami mat apart from the remaining five tatami mats is opened 4B as described above.
After the insecticide has been injected into all the tatami mats, the central tatami mat 1A is laid in its original position to complete the work. Here, the present inventors conducted an experiment to confirm the effect under the following conditions. Normal Kyoma Tatami (1910m in height)
m, a tatami floor 4 tatami 1 lateral 955mm), insulation board 4A in the thickness 1 5 m m, a thickness of 2 5 m m styrol board 4B, composed of insulation board 4C thickness 10 mm, styrene board 4B A groove R having a width of 5 mm and a depth of 3 mm was formed. The two main grooves Ra are 790 mm long and are provided at two positions 410 mm away from the center of the long side of the tatami mat 1 on both sides, while the branch grooves Rb have a length of 1640 m.
m, the two main grooves Ra communicate with each other and intersect with each other.
The distance from the end of the side surface where Ba is provided to the first branch groove Rb is 270 mm, and the distance from the first to the second branch groove Rb is 270 mm.
mm from the second to the third branch groove Rb is 240 mm
, Three intervals were provided. Thereafter, the insulation board 4A,
Styrol board 4B, insulation board 4C
Are sewn using a needle of 3 mm (the diameter of the needle hole P is 3 mm), and paper is arranged on the entire surface of the tatami 1 and the lid 4Bb is not fitted or exposed. When an insecticide was injected from the opening 4Ba using a compressor (not shown) at a pressure of 5 kg / cm,
In 30 seconds, the paper placed on the entire surface of the tatami mat 1 floated. That is, it was found that the insecticide spreads over the entire surface and the entire area inside the tatami mat 1 according to the present invention, so that the pest control effect is sure. And if it is Edo tatami (1760 mm in height and 880 mm in width) smaller than Kyoma tatami, it is clear that under the same conditions, it is possible to spread the insecticide over the entire surface and the entire area of the tatami in a shorter time. It is. The present invention is not limited to the above-described embodiment, but can be variously limited. For example, in the above embodiment, the styrene board 4B has two openings 4Ba, 4Ba.
And the main grooves Ra, Ra communicating with them are formed. However, as a mode corresponding to only claim 1, if the tatami mat 1 has an installation position determined according to the room, One of the openings 4Ba to be exposed or one when both are exposed
Only the main groove Ra, which is not communicated with the opening 4Ba, may be completed in the middle of the main grooves Ra. As described above, the lid 4Bb may be fitted into one of the openings 4Ba of the tatami mats 1 (the one that is not exposed), or the tatami mat 1A at the center and the tatami mats at the center. It may be fitted so as to close either one of the exposed openings 4Ba, 4Ba in the tatami 1 where both the openings 4Ba, 4Ba are exposed when the 1A is turned up. Further, for example, in the above embodiment, each layer in the tatami floor 4 is made of, for example, a styrene foam board, a plywood board of wood chip chips, or a board made of plastic or urethane having a predetermined hardness. Insulation board 4A, made of
It may be used instead of 4C. However, when a board made of rice straw is used in place of the styrene board 4B, a groove having a cross section having a predetermined passage is formed flat on the upper or lower surface of the board made of rice straw. By providing the same, it is possible to obtain the same operation and effect as described above, although it requires more labor and cost than the above-described embodiment. In the above embodiment, an insecticide is used to control pests. However, the same action and effect can be obtained by sending hot air instead of this, and there is no influence on the human body. This is advantageous in that the cost of the insecticide can be reduced. Also, the insecticide and hot air sent from the opening 4Ba can increase the main groove R by increasing the pressure of the compressor.
Needless to say, it can be made to reach every corner of the tatami 1 in a short time through a or the branch groove Rb. As described above, the method for controlling pests of a tatami mat according to the present invention is as described above.
Law, a two-layer structure even less without the Tatamiyuka, this layer forming a groove on the upper surface or lower surface of the intermediate or positioned beneath the layer of the structure, along with sewn integrally all the layers, the tatami A central part of the room, a plurality of tatami mats provided with an opening for feeding insecticide or hot air by communicating with the groove on one side
