Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 5 show a first embodiment of an artificial lawn 1 according to the present invention. This artificial lawn 1 is provided with a base 2 and a large number of imitation grass pieces 3 protruding upward. . A plurality of lawn imitation leaf pieces 3 are bundled to form a leaf piece bundle 4, and the artificial lawn 1 includes a plurality of leaf piece bundles 4. Each leaf bundle 4 is folded in half at the central portion in the longitudinal direction, and a root portion 5 is provided that binds and fixes the central portion (part) of the plurality of lawn imitation leaf pieces 3 in the longitudinal direction. It has been.

The base 2 is provided with a plurality of root pots 6 that are immersed downward. The root 5 of the leaf bundle 4 is inserted into the root pot 6 and the root 5 is fixed to the base 2 by the needle member 7. The needle member 7 is formed in a bifurcated shape having two needle tips.
The base 2 is made of flexible or hard plastic, rubber, or the like. The shape and size of the entire base 2 in plan view are not limited in any way. For example, the base 2 may be a square, a rectangle, a circle or the like having a length and width of about several tens of centimeters, or a tatami mat or a sheet. It can also be long.

In the base 2 in the illustrated example, the root pots 6 are arranged in an orderly manner vertically and horizontally via a convex base 8 having a square shape in plan view. The convex base 8 plays the role of providing predetermined rigidity by causing the root pots 6 to be regularly arranged at predetermined intervals and by causing the side cross-sectional shape of the base 2 to be uneven. Further, a plurality of (four) openings 9 having a triangular shape are provided on the upper surface of each convex base 8, and a rectangular through-hole 10 is provided between the convex base 8 and the convex base 8. Therefore, the water permeability is ensured in the base 2 by these.
The root pot 6 is formed by making the inside an open cavity with a leg portion 11 projecting in the shape of a bottomed cup on the lower surface side of the base 2 opposite to the convex base 8. The lower end surface of the leg portion 11 is a ground contact surface, and a drainage space can be secured on the lower surface of the base 2 by the height of the cup shape. A rib 12 is provided on the outer periphery of the lower end surface of the leg 11, and the bottom of the root pot 6 is formed as a raised bottom. That is, a raised bottom space 13 is formed inside the rib 12. Further, a pair of guide grooves 15 extending in the depth direction are formed on both sides (opposing positions) across the opening of the root pot 6 in the peripheral wall portion of the root pot 6. These guide grooves 15 are opened on the opening side of the root pot 6.

The root portion 5 of the leaf bundle 4 is pushed into the root pot 6, and the above-described bifurcated needle member 7 is driven so as to cross the upper center of the root portion 5. At this time, the needle member 7 straddles both sides of the opening of the root pot 6 and penetrates the needle tips on both sides to the bottom of the root pot 6.
The guide groove 15 provided in the root pot 6 can be used to specify the driving positions of both needle tips when the needle member 7 is driven in this way, and both needle tips can be moved when the needle member 7 is driven. It is also useful for guiding. Further, the bottom space 13 provided on the lower side of the bottom of the root pot 6 can be used as a leg even when the needle member 7 is driven into the bottom of the root pot 6 and penetrates through the bottom. 11 is used to accommodate the grounding as 11.

The needle member 7 may be a U-shaped staple.
The leaf piece bundle 4 is formed of a rope-like leaf piece bundle constituting material 23 as shown in FIG. This leaf bundle bundle constituting material 23 is obtained by bundling many twisted lawn imitation leaf pieces 3. In the illustrated example, a relatively small number of imitation leaf pieces 3 are once twisted as a small-diameter leaf piece bundle constituting material 25, and then a plurality of (three) pieces of this leaf piece bundle constituting material 25 are twisted to increase the diameter of the large diameter. The number of used lawn imitation leaf pieces 3 is increased with the leaf piece bundle constituting material 23. The lawn imitation leaf piece 3 is formed of a resin rich in flexibility and elasticity (shape restoration property), and has a cross-sectional flatness or a circular shape, which is as thin as a real lawn leaf shape. A coil-shaped twisted ridge may be attached to each lawn imitation leaf piece 3.

  A sunlight blocking sheet 17 that reflects sunlight is provided on the base 2, and the sunlight blocking sheet 17 is externally fitted to the middle part of the leaf bundle 4 protruding upward from the root pot 6 through the opening hole 19. The upper side of the lawn imitation leaf piece 3 protrudes above the sunlight blocking sheet 17 through the opening hole 19 of the sunlight blocking sheet 17. The sunlight blocking sheet 17 is composed of an aluminum foil sheet or an aluminum foil vapor deposition sheet. The solar light blocking sheet 17 has a thickness of about 0.01 mm to 0.5 mm, and is adhered to the base 2 with an adhesive or the like, or disposed on the base 2 without being bonded to the base 2. When the solar light blocking sheet 17 is made of an aluminum foil sheet, the solar light blocking sheet 17 does not allow moisture to pass through, but when the solar light blocking sheet 17 is made of an aluminum foil vapor deposition sheet, The shielding sheet 17 allows air to pass therethrough and moisture.

  According to the above-described embodiment, sunlight is reflected by the sunlight blocking sheet 17 disposed on the upper surface of the base 2 and the shade of the upper surface of the base 2 formed by the three groups of grass-like imitation leaf pieces is used. Even if it receives direct sunlight, even if it is exposed to direct sunlight, the effect of returning the reflected light to the air through the shade is obtained. In addition, the formation of three supple lawn imitation leaf pieces and a shade layer creates a temperature difference between the sun and the shade layer, which also generates air convection and promotes wind flow. For example, the cooling effect can be further obtained, and even under the base 2, the structure of the leg portion 11 allows for a good air passage and the cooling effect can be obtained in the same manner. Further, the water under the base 2 becomes a water channel, and water can be easily flowed. Next, since the lawn imitation leaf pieces 3 are crowded in a bundle shape, water flows at the time of rain water or watering, but the lawn imitation leaf pieces 3 are gathered and bundled at the root portion 5 of the lawn imitation leaf piece 3, so that the capillary phenomenon This leaves water particles. These water particles are evaporated by the solar heat of the daytime, and the vaporization heat (takes heat when the water evaporates) phenomenon is also obtained. Therefore, the present invention blocks the sunlight and cools the reflected light back into the air and obtains a water hammer effect due to the heat of vaporization, thereby reducing the room temperature in the building and reducing the heating and cooling consumption. It is possible to effectively reduce the amount of reflected heat due to the reflection of light, which is useful for suppressing global warming.

FIG. 6 shows a second embodiment of the artificial lawn 1 according to the present invention in which the shape of the base 2 is different. The base plate 2 used in the second embodiment is formed in a flat plate shape, and a bottomed cylindrical root pot 6 is immersed vertically and horizontally in the flat plate base plate 2. The other points are the same as those in the first embodiment.
FIG. 7 shows a third embodiment of the artificial lawn 1 according to the present invention in which the shape of the base 2 is different. Sandy soil 25 is provided on the sunlight blocking sheet 17, and the tip side of the lawn imitation leaf piece 3 protrudes upward from the sandy soil 25. The other points are the same as those in the first embodiment.

  In the case of the third embodiment, the sunlight (direct sunlight) is reflected on the sand soil 25 and the tip side of the lawn imitation leaf piece 3, and the sunlight that has passed through the sand soil 25 is reflected in the same manner as in the above embodiment. The solar light blocking sheet 17 can reliably reflect and emit upward. Also, the sand 25 separates the outside air from the upper surface of the building, and the earth and sand 25 that has been exposed to direct sunlight is heated to a certain extent, but the base 2 is installed on the rooftop of the building via the plurality of legs 11. Therefore, since air flows through the lower side of the base 2, almost no heat is transferred to the building side, and the heat of the heated earth and sand 25 can be released to the air side above the earth and sand 25.

  In the above-described embodiment, the base 2 is provided with a plurality of root pots 6 immersed downward, and the root 5 of the leaf bundle 4 is inserted into the root pot 6 and fixed to the base 2 by the needle member 7. However, instead of this, the artificial lawn 1 to which the present invention is applied is not limited to such a configuration, and for example, a large number of imitation grass pieces 3 protrude upward on a plate-like base 2. In short, in the artificial lawn in which a plurality of artificial lawn leaf pieces 3 are provided on the base 2 so as to protrude upward, a solar light blocking sheet 17 that reflects sunlight is provided on the base 2. What is necessary is just to do.
