2. Description of the Related Art Japanese Patent Publication No. 5-3367 discloses an insect insect net for a vehicle that prevents insects from entering from outside when a window glass of a vehicle door is opened.
JP-A-1-147117, JP-A-63-1831
No. 9 and Japanese Utility Model Laid-Open No. 55-19028 are known. Japanese Utility Model Publication No. 60-8397 is known as a method of covering the outside of a window with a net that can be wound into and unwound from a cylindrical container at an end of a roof of a vehicle (above a door).

[0003]

The object of the present invention is to provide a pantyhose that can be comfortably used without worrying about stuffiness and odor even when wearing pantyhose.

[0004]

All of these conventional insect repellent nets for vehicles have no insect repellent effect when the door is open, so that only windows can be opened to take a rest in the car instead of a tent. No adequate ventilation or ventilation was obtained.

[0005] The present invention has been made in view of the above problems, and has as its object to provide a material capable of obtaining an insect repellent effect, ventilation, and ventilation without opening and closing doors.

[0006]

The insect net for vehicles according to the present invention has a first mesh area of 9 × 10 ^{-4 to} 2.5 × 10 ^-1 c.
m ² , mesh weight 5 to 1000 g / m ² , number of meshes 1 × 10
An outdoor vehicle insect repellent porous membrane characterized by a porous membrane of ² to 1 × 10 ⁷ cells / m ² to Naruko. The outdoor vehicle insect repellent porous membrane according to claim 1, wherein the porous membrane is a fiber mesh. The outdoor vehicle insect repellent porous film according to claim 1, wherein the porous film is a polyester fiber mesh.

The above-mentioned net covering the entire vehicle has a mesh area of 9 × 10 ^{-4 to} 2.5 × 10 ^-1 cm ² , a weight of 5 to 1000 g / m ² , and a mesh number of 1 × 10 4. ² to 1 × 10
⁷ pieces / m ² is good. A more preferred range is that the mesh area is 1 ×.
10 ² to 1 × 10 ⁻¹ cm ² and weighs 20 g to 300 g
g / m ² , and the number of meshes is preferably 1 × 10 ³ to 4 × 10 ⁶ / m ² .

[0008] The size of the mesh is breathable is less than 9 × 10 ^-4 cm ² it is difficult to feel the cool breeze sensation in terms referred leave through the wind, a 2.5 × 10 ^-1 cm ² When it exceeds, the feeling of cool breeze is sufficient, but it facilitates the invasion of insects such as mosquitoes, bees, ants and centipedes. When the weight is less than 5 g / m ² , it is advantageous that it is lightweight, but it is generally easily caught and broken. If the number of meshes is less than 10 ² / m ² even if it exceeds 1000 g / m ² , the feeling of cool breeze is also reduced in terms of air permeability, and if it exceeds 1 × 10 ⁷ / m ² , the holes are small. It becomes too cool and the feeling of cool breeze drops. However, the shape of the mesh is not limited.

[0009] In addition to the method of producing meshes by knitting and weaving, these insect repellent nets can be formed by punching, cutting, dissolving, melting, etc. into a film-like material such as nonwoven fabric or film (including FRP). May be obtained, but a woven mesh is preferred. As the constituent material of the porous membrane of the present invention, fibers of polyester type, polyamide type, acrylic type, polyolefin type, etc. can be adopted, but it is preferable that the porous film is composed of polyester fibers.

The insect net may be colored or post-processed independently or in combination of achromatic colors including white and black to chromatic colors, fluorescent colors, transparent colors, metallic colors such as gold to silver, and phosphorescent. .

[0011] In addition, functionalities such as water repellency, antifouling property, antifungal property, deodorant property, flame retardancy, repellent effect and heat insulating effect may be applied singly or in combination to a raw material kneading method, copolymerization or post-processing. May be.

Acrylic resin, salt-based resin, urethane-based, polyester-based, ethylene-vinyl acetate-based resin, etc. for the purpose of imparting a functional agent or functionality in addition to the purpose of preventing hand feeling and misalignment. In addition to the type, a resin of a thermoplastic or thermosetting classification may be provided.

Further, as a method of covering and fixing the insect repellent net on a vehicle, as shown in FIG. 1, an end which is guided from the vehicle to the ground with a covering slope and a covering slope is obtained at an appropriate pin or on site. In the method of fixing using stones and woods that can be used, one end of the insect repellent net is processed so that magic fasteners, eyelets and ropes, fasteners, hooks etc. can be made around the vehicle ceiling as shown in Fig. 2. In addition to making a ring slightly smaller than the roof area, fixing it to the roof so that it does not shift, guiding it to the ground while holding a slope, and fixing it with the same end treatment as above, as well as an accordion curtain as shown in FIG. There is no restriction on the method of covering the entire area, such as by squeezing one end of the shaped insect net and freeing the other end, so that the squeezed side is the roof side of the vehicle and fixed to free ground. . Of course, an impermeable material may be partially combined.

The insect screen requires a large area net due to the features that cover the entire vehicle. In order to obtain this net, a net having a relatively narrow width may be enlarged by sewing, bonding, fusion or the like, but it is advantageous to use a net obtained by a net making method which is wide from the beginning.

(Example) A 250d black dyed yarn of polyester multifilament is driven at a width of 120 inches for both warp and weft at 20 yarns / inch, and the resulting net-like cloth is dipped with an acrylic resin emulsion so that no film is formed on the eyes. After that, filling was performed while blowing air. The basis weight of this resin processing net was about 60 g / m ² . Next, the 3 m mesh cloth was sewn with a length of 8 m to obtain a 6 m × 8 m mesh cloth. A vehicle having a vehicle height of 1.5 m and a vehicle length of 4.5 m was covered with the large mesh cloth from above the roof. Of course, the door that people could get on and off could be opened and closed. For fixing to the ground, the ends were held down with pins. In this state, 50
g was put in a container, ignited, all windows and all doors were closed, and left for a certain period of time until burning of the smoke generating agent was completed. Optometry sheets were placed on the floor for identification in the car. Next, all doors were opened to the maximum, and the appearance of smoke disappearing from the optometry sheet in the car was observed over time from the window on the windward side (air movement in the car was observed by this evaluation method, and ventilation was evaluated). The results are shown in the comments.

(Comparative Example 1) Using the same vehicle and net cloth as in the example, igniting the smoke generating agent with the net cloth attached only to the windows that can be opened and closed, and closing the window until the combustion of the smoke generating agent is completed. It was left for a certain time. Next, the window was opened to the maximum, and the state of the smoke disappearing on the optometry sheet in the car was observed over time from the window on the windward side. The results are shown in the comments.

[0017]

[Table 1]

From the above observation results, a large difference was observed in the time when the smoke disappeared between the example and the comparative example. A similar tendency was observed outdoors, and this excellent smoke emission means that it has excellent outside air invasion. Also, RV
It was easy and quick to set up where the vehicle was parked.
This is because there is no need for a pillar like a tent.

[0019]

According to the present invention, a tent is not required by using the inside of a vehicle for resting or sleeping in the outdoors, etc.
This makes it possible to provide an insect repellent and a porous membrane that can easily prevent invasion of bees and the like.
