Description

The present invention relates to a doorway closing fixture for a building that blocks light transmitted in the wavelength range in which the pests are sensitive and prevents the pests from actively flying by light.

In general, it is already known that insects have the phototaxis to fly in response to light stimulation, and the wavelength characteristics of insect phototaxis are 200 to 600 nm, centering on 360 to 380 nm, as shown in FIG. Many insects are active in response to light in this wavelength range. For this reason, conventionally, a method for controlling the wavelength of light at night is known as a pest control method. That is, it is a method of blocking light in the wavelength range to which insects are sensitive.

A sheet according to Patent Document 1 is known as one that cuts off such a wavelength region. This type of sheet substantially blocks light with a wavelength of 380 nm or less, makes the light transmittance of a wavelength of 400 to 480 nm or more 30% or less, makes the light transmittance of a wavelength 520 nm or more 50% or more, The sheet is characterized in that light transmission at a wavelength of 580 nm or more is not substantially blocked. Here, in order to ensure human visibility while having an insect repellent effect, the light transmittance of 400 to 480 nm in the human visible light region is set to 30% or less, and further the light transmittance of wavelengths of 520 nm or more It was thought that it was necessary to keep 50% or more.

In contrast, Patent Document 2 discloses a synthetic resin color chip mainly composed of one or more pigments selected from the group consisting of yellow, orange, blue and black pigments finely pulverized to optical transparency. A pest attractant inhibiting material containing an ultraviolet absorber in a substrate and having a light transmittance of 10% or less at a wavelength of 200 to 420 nm, 30% or less at a wavelength of 420 to 480 nm and 20 to 50% at a wavelength of 480 nm or more is disclosed. Yes. In addition, the following non-patent documents disclose the insect light-running characteristics and the attractiveness to color.

Japanese Examined Patent Publication No. 4-65651 Japanese Patent No.2682818 Prediction of larvae of legumes by yellow sticky traps and cocoon trays in institutional tomatoes, Akito Ozawa (3 others), Journal of Japanese Society of Applied Entomology, Vol. 42, No. 3, pages 141-147 Ecological studies of pests in cucumber cultivation facilities II.

However, depending on the color and film of yellow / orange film or sheet according to Patent Document 1, when used for partitioning the entrance of the building, etc., the insects in the outdoor part of the building are attracted to the building during the day. End up. This is because yellow reflected light attracts insects.

On the other hand, the anti-pest attractant according to Patent Document 2 significantly suppresses the attraction of insects by adjusting the light transmittance even at a wavelength of 480 nm or more and making it bright enough not to impair human visibility. In this way, the insect repellent effect is further enhanced. In this case, commercialization was performed in various hues, but green hues have been established in the market from the viewpoint of not hindering human visibility. Although films and sheets having such green hues have a high insect repellent effect, the problem of further improving the transparency in visible light remains.

In view of the above points, the present invention provides a door opening / closing tool for a building that has a high insect repellent effect with a simple structure, has a hue that does not hinder human visibility, and has high light transmittance. The purpose is to do.

According to the first configuration of the present invention, the above object is obtained by laminating a first layer of translucent film containing a yellow color material and a second layer of translucent film containing a blue color material. The first layer of translucent film constitutes the indoor surface of the building, and the second layer of translucent film constitutes the outdoor surface of the building, and the entrance / exit closure of the building Achieved by fittings.

In the building entrance closing closure according to the present invention, preferably, the light-transmitting film of the first layer has a light transmittance of 5% or less in a wavelength region of 450 nm or less and a light transmittance in a wavelength region of more than 550 nm. More than 80%.

In the door closing fitting according to the present invention, preferably, the light-transmitting film of the second layer has a light transmittance of 5% or less in a wavelength region of 350 nm or less and a light transmittance in a wavelength region of more than 400 nm. 50% or more.

The doorway closing fixture of the building according to the present invention preferably has a base fabric layer sandwiched between the light-transmitting film of the first layer and the light-transmitting film of the second layer.

According to the above configuration, light of a hue with low saturation is formed by canceling the color of the transmitted light by the yellow color material such as yellow / orange with the complementary color light by the blue color material complementary to the yellow color material. As a result, human visuality is not disturbed while obtaining a high insect repellent effect. Further, even during the daytime, the light reflected by the present pest attracting inhibitor has a hue different from the yellow hue such as yellow and orange, so that the pest attracting is suppressed. When the first layer containing the yellow color material and the second layer containing the blue color material are laminated, an effective entrance / exit fitting for the building can be obtained by laminating them. .

When the second layer is provided on the surface on the outdoor side, the second layer including the blue color material is disposed on the outdoor side, and the first layer including the yellow color material is not exposed to the outdoor side. Therefore, since the hues of yellow, orange, and the like due to the yellow color material are not visible from the outside, the pests are not attracted to the yellow color during the day, and an environment free of pests is created in the outdoor part of the building. Thereby, for example, when opening / closing the entrance / exit of the building where the door closing fitting of the main building is installed, it is possible to effectively suppress the entry of harmful insects into the building from the entrance / exit.

In addition, since the first layer containing the yellow color material is directed to the indoor side, for example, in the building, pests with habitual habits that are attracted by the reflected light of the yellow color such as yellow and orange are There will be no progress toward the back and you will be guided to the doorway. Furthermore, visually bright light by the yellow color material, that is, light having a wavelength of around 555 nm that humans feel bright is reflected to the indoor side, and the brightness of the building is improved.

When a yellow color material and a blue color material are contained in a single layer in a mixed state, the yellow color such as yellow and orange, and the blue color dye that is the complementary color and transparency It is comprised from the single layer which disperse | distributes and contains each pigment | dye by mix | blending suitably and forming a high pigment. Therefore, the manufacturing process is simplified and the manufacturing process can be performed at a lower cost.

If the yellow colorant has a light transmittance of 5% or less in the wavelength region of 450 nm or less and a light transmittance of 80% or more in the wavelength region beyond 550 nm, it is visible even when combined with the blue colorant. A high insecticidal effect can be obtained by largely blocking light in the wavelength region of 450 nm or less including light rays. Further, since most of the light in the wavelength region exceeding 550 nm is transmitted, the transmittance is higher than that of the conventional pest attractant and a bright field of view is obtained, so that human visibility is not hindered.

When the blue colorant has a light transmittance of 5% or less in the wavelength range of 350 nm or less and a light transmittance of 50% or more in the wavelength range of more than 400 nm, the ultraviolet ray is combined even with the yellow colorant. By significantly blocking light in the wavelength region of 350 nm or less including, the adverse effects of ultraviolet rays on human vision can be eliminated. Similarly to the yellow colorant, it transmits light in the wavelength range exceeding 550 nm to a certain degree, which increases the transmittance compared to conventional insect attractant prevention materials and provides a bright field of view. There is no hindrance.

In the case of having a base fabric layer sandwiched between translucent films, it is possible to appropriately control the reflection of external light depending on the color of the base fabric and the size of the grid.

In this way, according to the present invention, a door opening / closing device for a building that uses a pest attraction preventing material having a hue that does not impair human visibility and that has a high insect repellent effect and that is excellent in light transmittance. Can be provided.

FIG. 1 shows a first embodiment of a pest attraction preventing material constituting a doorway closing fitting according to the present invention. In FIG. 1, a pest attracting inhibitor 10 is composed of a translucent film having a two-layer structure, and is composed of a first layer 11 and a second layer 12 that are sequentially laminated. Here, the translucent film is made of, for example, a soft vinyl chloride resin, and is molded to an appropriate thickness in a state in which a color material is mixed as will be described later. As shown in FIG. 6, the pest attracting material 10 is suspended and installed like a curtain at an entrance 21 of the building 20, and constitutes a doorway closing fixture.

The first layer 11 is a translucent film containing a yellow color material. A translucent film containing such a yellow colorant should be mixed with a yellowish orange dye such as yellow or orange or a highly transparent pigment as a pigment and mixed into the material of the translucent film. Is manufactured.

Specifically, the yellow color material can block light in a wavelength region of 450 nm or less by using a conventionally known yellow color material such as yellow or orange. Furthermore, as is well known, the light transmittance in the wavelength region near 450 nm can be set lower by using a color material that is orange rather than yellow and by adjusting the concentration of the color material to be darker. In addition, if it has the said optical characteristic, it is also possible to utilize the translucent film colored in the yellow system | strain commercially available.

Such a prototype sample S1 of the first layer 11 is composed of the following composition, for example, and has the optical characteristics shown in FIG. As shown in FIG. 2, the prototype sample S1 of the first layer 11 has a light transmittance in the wavelength region of 450 nm or less of 5% or less and a light transmittance in the wavelength region of over 550 nm of 80% or more.

S1: Translucent film containing yellow color material 0.3 mm composition Polyvinyl chloride resin 100% by weight Phthalic acid plasticizer 40% by weight
Ba / Zn stabilizer 2.0% by weight Benzophenone UV absorber 0.2% by weight Isoindolinone yellow pigment 0.4% by weight Acrylic processing aid 1.0% by weight

The second layer 12 is a translucent film containing a blue color material. A translucent film containing such a blue colorant is blended with, for example, a blue color dye such as blue violet or a highly transparent pigment, and mixed into the material of the translucent film, Manufactured. In addition, if it has the said optical characteristic, it is also possible to utilize the translucent film colored in the blue system | strain commercially available.

Such a prototype sample S2 of the second layer 12 is composed of the following composition, for example, and has the optical characteristics shown in FIG. As shown in FIG. 3, the prototype sample S2 of the second layer 12 has a light transmittance of 5% or less in a wavelength region of 350 nm or less and a light transmittance of 50% or more in a wavelength region exceeding 400 nm, and a wavelength of 600 nm. In the vicinity, it has a light transmittance of about 60%.

S2: Translucent film containing blue color material 0.3 mm composition Polyvinyl chloride resin 100% by weight Phthalic acid plasticizer 40% by weight
Ba / Zn stabilizer 2.0% by weight Benzophenone UV absorber 0.2% by weight Copper phthalocyanine blue pigment 0.04% by weight Acrylic processing aid 1.0% by weight

Then, the first layer 11 and the second layer 12 thus manufactured are laminated and fixed to each other by adhesion or the like, whereby the pest attraction preventing material 10 is completed.

The pest attraction preventing material 10 according to the present embodiment is configured as described above, and operates as follows. The pest attracting inhibitor 10 has the first layer 11 and the second layer 12 laminated to each other, so that the transmitted light has optical characteristics obtained by superimposing the optical characteristics of the first layer 11 and the second layer 12. Become. In other words, the light incident on the pest attractant blocking material 10 is multiplied by the yellow hue such as yellow or orange by the first layer 11 and the blue hue by the second layer 12 and cancels each other by the complementary color action. As a result, a hue with low saturation is formed and the insect pest attraction preventing material 10 is transmitted. At that time, incident light is largely blocked by the first layer 11 in a wavelength region of 450 nm or less. At the same time, the first layer 11 transmits 80% or more in the wavelength region exceeding 550 nm, and the second layer 12 transmits 50% or more in the wavelength region exceeding 400 nm, thereby impairing human visibility. Without providing a bright view.

Specifically, the prototype sample S3 was produced by combining the prototype sample S1 and the prototype sample S2.

That is, the prototype sample S1 was used as the first layer 11 and the prototype sample S2 was used as the second layer 12, and these were bonded together to produce the pest attracting inhibitor 10 as the prototype sample S3. This prototype sample S3 has the light transmittance shown in FIG. 4 and the light reflectance shown in FIG.

Regarding transmitted light, as shown in FIG. 4, since it has a light transmittance of 5% or less in a wavelength region of 450 nm or less, sufficiently high insect repellent efficiency is obtained, and in a wavelength region exceeding 500 nm, 50% or more Therefore, it is confirmed that human visibility is not hindered.

As for reflected light, it can be easily confirmed that the hues of both surfaces are different even when viewed by human eyes. However, as shown in FIG. 5, a characteristic curve indicated by symbol A is obtained on the surface of the first layer 11 side. In addition, a characteristic curve indicated by symbol B was obtained on the surface on the second layer 12 side. In this case, particularly on the surface of the prototype sample S2 side as the second layer 12, it can be seen that the wavelength is different from the yellow hue such as yellow and orange. Therefore, since it has a hue different from that of yellow systems such as yellow and orange that attract pests during the day, the attraction of pests is suppressed.

Next, when the insect pest attracting inhibitor 10 is installed as described below, the insect repellent effect is further enhanced. That is, for example, as shown in FIG. 6, the insect pest attraction prevention material 10 is installed in a curtain shape so as to close the entrance / exit 21 at the entrance / exit 21 of the building 20 and constitutes the entrance / exit closing fixture of the building To do. At that time, the pest attracting prevention material 10 is installed so that the second layer 12 containing the blue color material faces the outdoor side of the building 20, that is, the first layer 11 containing the yellow color material is not exposed to the outside. Is done.

According to the entrance / exit closing fixture of the building thus installed, the light leaking outside from the inside of the building 20 through the pest attraction prevention material 10 is 450 nm or less based on the optical characteristics of the pest attraction prevention material 10. Since the light in the wavelength range is 5% or less and almost no light in the wavelength range that causes pest attraction is included, it is possible to greatly suppress the pest being attracted by the light leaking from the building, especially at night, An environment free of pests can be created outside the building. As a result, invading pests from the doorway 21 into the building 20 is also suppressed, and a high insecticidal effect is obtained. In addition, since there is 50% or more of light in the wavelength range exceeding 550 nm, sufficient brightness is obtained and human visuality is not hindered. That is, it is easy to visually recognize the inside of the building from outside the building.

Furthermore, since the second layer 12 of the pest attraction prevention material 10 is installed facing the outside at the entrance / exit 21 of the building 20, the light reflected on the outer surface of the pest attraction prevention material 10 is yellow or orange. Since the wavelength is different from the hue of the system, pests are not attracted by the reflected light of the second layer 12 during the day.

In addition, at the doorway 21 of the building 20, the first layer 11 of the pest attraction prevention material 10 is arranged inward, so that the light reflected on the inner surface of the pest attraction prevention material 10 is yellow, orange, etc. A pest that has entered the wavelength range of the yellow line and has entered the building 20 is attracted toward the entrance / exit 21 and can be prevented from entering deep inside the building 20. Furthermore, since the inside of the building 20 is felt bright by this reflected light, human visibility is enhanced.

FIG. 7 shows a configuration of a second embodiment of the pest attracting prevention material constituting the doorway closing fixture according to the present invention. In FIG. 7, the pest attraction preventing material 30 is a light-transmitting film made of a light-transmitting film having a single-layer structure and containing a yellow color material and a blue color material in a mixed state. Here, the yellow system color material and the blue system color material are the yellow system color material and the blue system color material mixed in the first layer 11 and the second layer 12 in the pest attraction prevention material 10 according to the first embodiment, respectively. It is almost the same.

Such a prototype sample S4 of the pest attraction preventing material 30 is composed of, for example, the following composition, and the light transmittance and the light reflectance are as shown in FIGS.

S4: Second embodiment (translucent film having a single layer structure) 0.6 mm composition Polyvinyl chloride resin 100% by weight Phthalic acid plasticizer 40% by weight
Ba / Zn stabilizer 2.0% by weight Benzophenone UV absorber 0.2% by weight Isoindolinone yellow pigment 0.2% by weight Copper phthalocyanine blue pigment 0.02% by weight Acrylic processing aid 1.0% by weight

As shown in FIG. 8, the prototype sample S4 of the pest attractant blocking material 30 has a light transmittance of 5% or less in a wavelength region of 450 nm or less as shown in FIG. Since the light transmittance is 50% or more in the wavelength range exceeding 500 nm, it is confirmed that the human visibility is not hindered. This light transmittance characteristic is almost the same as that of the prototype sample S3 shown in FIG.

As shown in FIG. 9, the reflected light has a light reflectance of about 5% in the wavelength region of 450 nm or less and a light reflectance of about 12% in the wavelength region exceeding 500 nm. Comparing this with FIG. 5, it can be seen that 500 nm or less is close to yellow, and 500 nm or more is close to blue. This shows that the hue is not yellow. Therefore, the attraction of pests is suppressed during the day.

According to the pest attraction preventive material 30 having such a structure, the transmitted light acts in the same manner as the pest attraction preventive material 10 shown in FIG. Can be manufactured in a short time, and can be manufactured easily and at low cost.

In the pest attraction preventing material of the first embodiment described above, a reinforcing mesh-like cloth (base cloth) may be sandwiched between the first layer and the second layer. Even in such a case, it is clear that the effect of the present invention is exerted. In particular, since the mesh portion reflects light without transmitting light, the transmitted light is suppressed in the above description, and the reflection is related. The effect becomes stronger.

Specifically, a reinforcing mesh-like cloth (base cloth) was sandwiched between the above-described prototype sample S1 and prototype sample S2, thereby providing a base fabric layer and producing prototype sample S5. The color of this base fabric is gray near white. That is, the prototype sample S1 is used as the first layer 11, the prototype sample S2 is used as the second layer 12, and a reinforcing mesh-like cloth (base fabric) is sandwiched between them and bonded together, thereby producing the prototype sample. A pest attractant inhibiting material 10 as S5 was produced. This prototype sample S5 has the light transmittance shown in FIG. 10 and the light reflectance shown in FIG.

Regarding transmitted light, as shown in FIG. 10, since it has a light transmittance of 5% or less in a wavelength region of 450 nm or less, sufficiently high insect repellent efficiency is obtained, and in a wavelength region exceeding 500 nm, 40% or more Therefore, it is confirmed that although the transmittance is lower than that of the prototype sample S3 shown in FIG. 4, it does not hinder human visibility.

Regarding the reflected light, as with the prototype sample S3, it can be easily confirmed that the hues of both surfaces are different even when viewed with the human eye, and as shown in FIG. A characteristic curve indicated by symbol D was obtained on the surface on the second layer 12 side. In this case, similar to the prototype sample S3, it can be seen that the wavelength on the side of the prototype sample S2 as the second layer 12 is different from the yellow hue such as yellow and orange. Therefore, since it has a hue different from that of yellow systems such as yellow and orange that attract pests during the day, the attraction of pests is suppressed. It can also be seen that the reflectance increases on both sides compared to the prototype sample S3 shown in FIG.

Furthermore, in the insect pest attraction preventing material of the second embodiment described above, a reinforcing mesh-like cloth (base cloth) may be disposed within the thickness of the light-transmitting film having a single-layer structure. Further, the insect pest attracting material of the second embodiment described above may be laminated to form a two-layer structure, and a reinforcing mesh-like cloth (base cloth) may be sandwiched between the two layers. Even in such a case, it is clear that the effect of the present invention is exerted. In particular, since the mesh portion reflects light without transmitting light, the transmitted light is suppressed in the above description, and the reflection is related. The effect becomes stronger.

Specifically, a reinforcing mesh-like cloth (base cloth) is sandwiched between two-layered translucent films obtained by laminating two films having the thickness of the prototype sample S4 described above that is half (0.3 mm). Thus, a base fabric layer was provided, and a prototype sample S6 was produced. The color of this base fabric is gray near white. This prototype sample S6 has the light transmittance shown in FIG. 12, and also has the light reflectance shown in FIG.

Regarding transmitted light, as shown in FIG. 12, since it has a light transmittance of 5% or less in a wavelength region of 450 nm or less, sufficiently high insect repellent efficiency is obtained, and in a wavelength region exceeding 500 nm, 40% or more Thus, it is confirmed that the transmittance is lower than that of the prototype sample S4 shown in FIG. 8, but the human visibility is not hindered, as in the prototype sample S5.

As for the reflected light, as shown in FIG. 13, it has a light reflectance of about 5% in a wavelength region of 450 nm or less, and a light reflectance of about 15% in a wavelength region exceeding 500 nm. It can be seen that the reflectance increases as compared with the prototype sample S4 shown in FIG. Comparing this with FIG. 11, it can be seen that 500 nm or less is close to yellow, and 500 nm or more is close to blue. This shows that the hue is not yellow. Therefore, the attraction of pests is suppressed during the day.

The present invention can be implemented in various forms without departing from the spirit of the present invention. For example, in the above-described embodiment, the prototype samples S1 to S4 have been described as an example. However, the present invention is not limited thereto, and the light transmittance is a wavelength range that significantly cuts light in a wavelength region of 450 nm or less and exceeds 550 nm. What is necessary is just to cut the light appropriately. The material of the sheet may be acrylic, PET, polycarbonate or the like. Regarding the color of the base fabric, various colors such as white, black, yellow, and green can be used as well as gray close to white.

In the embodiment described above, with reference to FIG. 6, the pest attracting prevention material 10 is installed suspended like a curtain at the entrance / exit 21 of the building 20, but is not limited thereto, for example, a film or sheet-like pest. It is obvious that the attraction preventive material 10 may be disposed on the glass surface provided in the window portion of the building 20 by pasting or the like. Moreover, even if the 1st layer and the 2nd layer are not adhere | attached, they may be welded, or may be installed as a separate body with a gap.

As described above, according to the present invention, with a simple structure, a high insect repellent effect can be obtained, a hue that does not hinder human visibility, a high light transmittance, and an extremely excellent building. A doorway fitting is provided.
