Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention focuses on rainwater squid, which is a source of mosquitoes in a living environment, and aims at eliminating the source of mosquitoes themselves. , In general residential premises,
And according to the shape of perforated lids of all types of existing and new "rainwater masu" installed on roads around it, cut freely with scissors etc. and spread under the lid or adhere to the back of the lid This is a general-purpose, mosquito-proof net that can achieve mosquito-proofing effects alone. * What is general-purpose? It can be applied freely to all kinds of existing and new types of rainwater divers, and it can be used for mosquito-proof purposes. Vents, pet / livestock sheds, rain cisterns, garden tubs, etc.). 2. Description of the Related Art At present, there is no uniform standard for rainwater trout. The material, size, and shape of the lid are extremely diverse, and there are many custom-ordered products. Slightly different, and it is constantly improving and changing year by year. On the other hand, what is common to all stormwater
(See Fig. 1) To prevent clogging of the upstream and downstream pipes with sediment, etc., there is always a sedimentation tank for sediment, trash, etc. at the bottom of the main body, and rainwater, muddy water, trash, dead leaves, etc. stay throughout the year. The lid has a circular or rectangular hole or a grid-like hole because of the need for water permeability, ventilation, etc., so that insects such as mosquitoes can enter and exit freely, In particular, it is a perfect and optimal breeding place for mosquitoes that are harmful to humans. For reference (see Fig. 2) * 1. Mosquito reproductive power is tremendous, one female mosquito has a life of about 1
During the month, 4 to 5 eggs are laid, and the number of eggs laid at a time is 50 to 60. The eggs become adults 9 to 14 days after being laid. In rainwater without natural enemies such as fish, the probability of becoming an adult is extremely high. In addition, female mosquitoes have the habit of instantaneously and skillfully sucking blood from humans and animals before laying eggs, in which case they give unpleasant scratches and pathogenic bacteria to humans. In addition, they overwinter in the state of eggs, larvae, pupae, etc., and when the temperature reaches an appropriate level the following year, they become adults and repeat the above breeding. * 2. In Japan, around 6-9 every year, female mosquitoes are swarming near the rainwater masquerade in the garden in search of a blood-sucking partner, and when the lid is opened, a small mosquito that has just emerged is waiting in the rainwater masque, In addition, observing the bottom of the water reveals that many burrs are active. * 3. In order to realize a living environment free of mosquitoes, the ecology of mosquitoes (i) eliminates stagnant water in and around the premises (ii) rainwater and other unavoidable stagnant waters are protected by mosquito nets This is possible by continuously blocking the spawning pathway of female mosquitoes. Eliminating mosquito sources from the living environment at low cost and in a simple way is now an important issue for environmental improvement both domestically and globally, but rainwater is the most familiar source. However, no effective countermeasures have been taken against this and the situation is currently blind. Also, it can be said that no mosquito and insect repellent measures have been taken against rainwater masu even in the latest new construction. Rather, it is commonplace to have mosquitoes in summer. Therefore, at present, measures against mosquito harm are mainly drug and pharmacy. However, in order to make the modest enjoyment in the garden in the summer (gardening, horticulture, watering in the evening, cool water for children, barbecue, etc.) and the environment of pets more comfortable, inexpensive, simple and simple other than medicine and pharmacy. There is a need and urgent need for sustainable measures. The annual mosquito protection costs (various sprays, mosquito nets, etc.) and the mosquito-related medical costs of each household used in summer should not be ignored for households. Mosquitoes flying from distant places such as dobu rivers, rice fields, ponds and swamps are unavoidable, but if the present invention is applied to existing and newly installed rainwater masu, at least the flying mosquitoes will surely be prevented from breeding in the living environment it can. There are an average of four rainwater pits on a single-family home, which is a great breeding ground for mosquitoes. This is very important. The various types of current rainwater trout are classified as shown below (Table 1). Rainwater trout without mosquito control measures, that is, B, C,
E type is overwhelmingly large, regardless of existing or new construction,
It is still increasing. F-type (rainwater lid with insect net) is described in some manufacturers' catalogs, but is expensive, and there are few construction examples.
Its spread will be quite delayed. See (FIG. 3) (FIG. 4) (FIG. 5) (FIG. 6) (7) (8) for various and various examples of the shape of the rainwater lids of the B, C, E and F types. [Table 1] [Problems to be Solved by the Invention] The function and purpose (*) of the lid hole of the current rainwater basin (regardless of new construction, existing construction, size, shape, material) are not impaired, and In order to prevent adult mosquitoes from getting in and out of the hole, we provide inexpensive materials that can be easily (*) constructed by amateurs (not mosquito nets, but versatile mosquito nets themselves) and how to use them. Therefore, the main objective is to eliminate the generation of unpleasant and harmful mosquitoes from the living environment. * Function and purpose of the hole in the lid = (1) For inflow and permeation of surface rainwater (2) For opening and closing during cleaning and repair (3) For ventilation * Easy even for amateurs = Cut with scissors or cutter knife and lid Just laying or gluing on the back side of the rainwater [Means for solving the problem] Rainwater satisfying the following conditions
Provide versatile and anti-mosquito nets to the market with instructions for use. 1. Conditions of the mosquito net of the present invention Material: Polyethylene is considered to be optimal (a synthetic resin or metal other than the above may be used as long as the material satisfies the following conditions with a thickness of about 1 mm.
Experiments have determined that polyethylene best satisfies the following conditions: ) It can be cut easily with paper cutting scissors etc. It can be folded easily by hand, it does not crack, it has weather resistance, it has durability, it has heat resistance (such as tobacco fire) It has corrosion resistance (it does not rust and does not rot) 1. Low temperature elasticity, low cost, and safety (safety at cutting, safety of cut). Easy to form mesh with a thickness of about 1mm. Thickness: about 1.0 to 1.3 mm3. Mesh 18-20 mesh (1,441-1.
270 mm) square or circular hole (adult mosquitoes cannot enter and exit). i Uniform uniform mesh type (sufficient for small masquerade) or ii Mesh type with zonal reinforced portions with a width of about 5 mm arranged in a grid at intervals of about 5 cm (for medium and large sized squares) , Ii). Molding method It is not good to use a yarn knitting type such as a net of a single-piece screen door because the cut part is easy to fray and slip easily. It is thought that mass production is possible with existing technology. 5. Color Gray to beige color, good measurement, easy to put mark. It is a color that can be easily used for purposes other than rainwater masque. 6. Product size (Reference example) For small masquerades: 1 piece per 50cm width x 50cm length or ii 50cm width x 2m length flat-sheet quantity sales, or roll-roll sales (small rainwater masu in general residential premises) Suitable (see Fig. 9) For medium and large masuma-Rolled rolls measuring about 1m wide x several meters long, or rolled (suitable for medium and large rainwater masu on roads, parks, schools, etc.) (Order omitted)-Custom products cut by applying the following methods (I), (II) and (III) to fit the size and shape of the specific rain water basin (installed in multiple same rain water basins) [Embodiment of the present invention] An embodiment (basic construction method) of the mosquito net according to the present invention is described in the following I.I. II. III. The case of the rainwater masturbation (FIG. 1), which is most frequently installed in a general detached house premises, will be described as a typical example (rainwater squid at the applicant's house). By using the material and thickness under the above conditions, even an amateur can easily and safely cut with paper cutting scissors or the like. Construction method (Points of contents described in the instruction manual of the product) II. III. From among the three methods, the method best suited to the target rainwater squid can be selected and installed. (See FIG. 10) Remove the lid, wash the lid and the lid receiving frame with a scourer, etc., and clean the soil and dirt. Also clean the bottom. 2. Lay the mosquito net on the back of the rainwater masque lid and cut it into a size plus a bending allowance to bend about 2.5 cm from the periphery of the back of the lid (more precisely, equivalent to the thickness of the mosquito lid). . (How to draw the cutting line = Place the lid face up on the net, determine the position in consideration of the bending allowance, and draw the outline of the back of the lid with a pencil etc.) Cut the four corners and fold along the back of the lid. 4. Spread the mosquito net over the lid receiving frame. 5. Put the lid on. (The four-sided bending allowance is fixed by the weight of the lid.) If the net protrudes around the lid, cut it with scissors. That's it. * This method can be applied to circular and grid-shaped lids. If the work is to be performed on a circular mason, see (Fig. 15). * This method is described in II. III. Although the net use area is the largest compared with, there is no need to worry about bending because it is easy to install and no adhesive is required. (See FIG. 11) Remove the lid, wash the lid and the lid receiving frame with a scourer, etc., and clean the soil and dirt. Also clean the bottom. 2. Lay the mosquito net on the back of the lid, cut in one direction only, about 2.5 cm from the back of the lid (accurately, equivalent to the thickness of the lid), plus bends on both sides, and cut in one direction ,
Cut to a width where the entire surface of the lid hole is sufficiently hidden without any bending allowance. 3. The two allowances are folded along the back of the lid. 4. Lay the net so that the lid hole is at the center. 5. Put the lid on. (The two-way bending margin is fixed by the weight of the lid.) If the net protrudes around the lid, cut it with scissors. That's it. * This method is described in Method I. It is easier to cut than mosquito nets, and the area of mosquito net use is slightly smaller than that of mosquito nets. Confirmation is required. * This method can be applied to circular and grid-shaped lids. However, for grid-shaped lids, method I. Is optimal. See Figure 15 for a circular case. (A double-sided adhesive tape, a gum tape, etc. that can bond the material of the net and the material of the lid are required. Commercially available products can be sufficiently bonded.) (See Fig. 12) Remove the lid, wash the back of the lid and the lid receiving frame with water, clean dirt, dirt, etc., and dry the back of the lid thoroughly.
Clean the bottom of the lid. 2. Cut the mosquito net at least 3cm larger than the area around the lid hole. 3. Recheck the cleaning and drying of the back of the lid. 4. Adhere the net firmly to the back of the lid hole with double-sided adhesive tape. 5. As a precautionary measure, secure the entire upper periphery with adhesive tape. 6. Put the lid on. That's it. * This method is as follows. Although a double-sided adhesive tape or the like is required, there is an advantage that the used area of the mosquito net can be saved considerably. 2. Not suitable for gridded lids. 3. It cannot be applied to the case where the back surface of the lid is uneven. It should be noted that the methods I, II, and III can be easily applied to rainwater basins other than the above (FIG. 1) depending on the structure and size of the basin. See (FIG. 13) (FIG. 14) (FIG. 15) for some application examples. [Effects of the Present Invention] Even laymen can eliminate the source of mosquitoes in our gardens cheaply, safely and easily.
(Everyone can create a garden without mosquitoes that can feel like playing inside) 2. If implemented in close proximity, a comfortable and sanitary living environment free of mosquitoes will be realized more widely. 3. Since it is a versatile net rather than a net lid, it can be freely applied to all types of existing and new rainwater lids. 4. It has the effect of reducing mosquito repellent application and is an environmentally friendly method. 5. Cost saving of mosquito repellents (mosquito repellents, itching, insecticides, etc.). 6. Reduced discomfort, illness, and scratches caused by mosquitoes, and reduced medical costs. 7. A more hygienic and comfortable environment is possible for pets and livestock. 8. Environmental improvement is possible not only for houses, but also for roads, shopping streets, parks, schools, etc. 9. Applicable to rainwater masu in the whole world and can contribute to improving the living environment in the world. 10. The sediment such as earth and sand, dead leaves, and garbage is reduced at the bottom of the rainwater, and it becomes clean. (Simple clogging is necessary periodically to eliminate clogging of the net.) Even a small clogging of the mesh has almost no adverse effect on the permeability of the lid hole. Cleaning can be easily done by removing the lid. (Since it is desirable to temporarily remove the mosquito net during heavy rain, it is desirable to use (I) or (II) if possible). The problem of nature and ecosystem destruction does not arise even if mosquito numbers decrease. 13. It can control insects other than mosquitoes that use rainwater masu as a breeding source.
(Slicks, spiders, worms, cockroaches, moths, squats, etc.) It can be widely applied to insects other than rainwater basins (ventilation vents, underfloor vents, pet livestock sheds, reservoirs, Tsukubai, etc.). 15. When small items such as valuables (rings, watches, fountain pens, coins, etc.) are dropped on the rainwater basin, they can be easily picked up without falling to the bottom. 16. It is very effective if implemented in the housing complex, the area, and the local government.
