DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial lawn mainly laid on a veranda, a rooftop, a poolside, or the like.

[0002]

2. Description of the Related Art Conventionally, as an artificial lawn used for a veranda or the like, a leaf piece 32 is woven into a fiber base cloth 31 as shown in FIG.
3 and FIG. 24 and FIG.
As shown in FIG. 5, there is a plastic integrated type in which the base 35 and the leaf piece 36 are integrally formed.

[0003]

However, the carpet-shaped artificial turf has a suppleness but is a base cloth 31 and a supple leaf piece 32. There was also water retention, and it was poorly dried when exposed to water, and it was uncomfortable and unpleasant due to dampness and mold. In addition, since the root of the leaf piece 32 was shallow, there was also an inconvenience in that the root was lacking in stand-up (it would be difficult if it was not densely packed).

[0004] In the case of a plastic-integrated type described later, the base 35 and the leaf 36 are integrally formed of the same resin, and the base 35 and the root of the leaf 36 are continuous with each other. And because the leaf piece 36 has a waist configuration,
The drainage is good, but there is no suppleness and the feel and texture are bad.
Further, since the base 35 and the root of the leaf piece 36 are continuous, an external load (walking, sitting, etc.) is obtained.
The load burden received at the root when receiving etc. is enormous,
There was an inconvenience of being worn out early, such as being easily torn or damaged. In addition, since it is made of only plastic material, when it is used outdoors, there is an inconvenience that it is quickly degraded under the influence of direct sunlight or the like, and there is a problem that the degree of expansion and contraction due to a temperature change is so large that it becomes curved.

[0005] In view of the above problems, the present invention has good drainage, good standing of leaf pieces, is soft to the human body, hardly damaged, hardly degraded by direct sunlight, and can sufficiently withstand long-term use. It is like that.

[0006]

A first technical means of the present invention for solving this technical problem is to provide a base 1 with a plurality of water holes 2 and projecting downward from the base 1. A plurality of cylindrical leg portions 3 are provided at intervals from each other, and the lower portion of the lawn imitation leaf piece 7 is bundled in the leg portion 3 so that the lawn imitation leaf piece 7 projects upward from the leg portion 3. The point is that it is inserted and fixed.

According to a second technical means of the present invention, a plurality of water holes 2 are provided in a base 1 and a plurality of cylindrical legs 3 projecting downward from the base 1 are spaced from each other. And an insertion opening 11 having an opening area larger than that of the leg portion 3 is provided between the base 1 and the leg portion 3.
The lower part of the lawn imitation leaf piece 7 is inserted and fixed in the form of a bundle into the leg 3 from the insertion opening 11 so that the leaf 3 projects upward from the leg 3.

[0008] A third technical means of the present invention is that the leg 3
Is formed in a cylindrical shape with a bottom, and a drain hole 5 is provided at the bottom of the leg 3.

[0009]

The leg (3) projecting downward from the base (1) provides a space (height) between the base (1) and the installation surface (4) of the veranda or the like, so that rainwater and sprinkling water can be quickly flown at the lower part. Moreover, the lower part (root part) of the lawn imitation leaf piece 7 can be formed long (deep). The lower part of the lawn imitation leaf piece 7 is bundled and fixed in the leg part 3 so as to be fixed.
And the bundle of the lawn imitation leaf pieces 7 inserted into the leg portion 3, the leg portion 3 has an appropriate flexure, and the burden on the human body is reduced. Further, the root portion of the lawn imitation leaf piece 7 can be formed long (deep), which improves the standing ability of the lawn imitation leaf piece 7 (increases restoring force). Further, since the lawn imitation leaf piece 7 can be formed into a bundle, the flexible lawn imitation leaf piece 7 can also have a waist. Lawn imitation leaf piece 7 in leg 3
The flexibility (displacement, etc.) reduces the impact load from the outside and helps to prevent tearing.

Further, since the lawn imitation leaf piece 7 and the leg 3 are separate bodies, the firm base 1 and the flexible lawn imitation leaf piece 7 or the waisted lawn imitation leaf piece 7 and the base 1
Variations of the lawn imitation leaf piece 7 and the lawn imitation leaf piece 7, variations in the lawn imitation leaf piece 7, variations in the volume of the lawn imitation leaf piece 7 depending on the size of the lawn imitation leaf piece 7 mixed for each base 1, and the size of the cylindrical hole of the leg 3. Is obtained.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. 1 and 2, reference numeral 1 denotes a flat base, which is made of a synthetic resin such as ethylene vinyl acetate. The base 1 is provided with a large number of circular water holes 2.
The base 1 is provided with a large number of legs 3 immersed downward at intervals. The leg 3 has a bottomed cylindrical shape, protrudes downward from the base 1, and positions the base 1 above an installation surface 4 such as a veranda. A drain hole 5 is provided at the bottom of the leg 3.

Reference numeral 7 denotes a turf imitation leaf piece, which is made of, for example, a nylon-based synthetic resin. The lower part of the turf imitation leaf piece 7 is inserted and fixed in a bundle in the leg 3. , And project upward from the leg 3. According to the configuration of the above embodiment, a more excellent artificial lawn can be provided by the combination of the base 1 and the lawn imitation leaf piece 7. That is, since the base 1 and the lawn imitation leaf piece 7 are configured separately,
In the case of the base 1, it is possible to provide a structure having particularly high waist strength, excellent cushioning properties, and excellent water permeability and water flowability, and in the case of the lawn imitation leaf piece 7, a variation of the lawn imitation leaf piece 7. It is possible to cope with a change in hardness or color of the lawn imitation leaf piece 7 according to the use and purpose. In addition, since the lawn imitation leaf piece 7 is bundled and has a configuration that is rich in standing and restoring properties by root insertion, water retention of water is almost eliminated,
Only the minute moisture remaining due to the capillary phenomenon (attached near the root portion squeezed to the bundle of lawn imitation leaf pieces 7) is retained, and the lawn imitation leaf piece 7 can be moist and supple.
Also, by imposing a lawn imitation leaf piece 7 on the upper surface of the base 1,
Direct sunlight is blocked, and the durability of the base 1 can be further improved. In addition, since the lawn imitation leaf piece 7 is bundled and the root is inserted, the load on the lawn imitation leaf piece 7 due to treading or the like can be reduced, and a comfortable artificial lawn can be provided for a long period of time.

First, in the base 1, a large number of water holes 2 are arranged on the base 1, and legs 3 projecting downward from the base 1 are installed, so that water can be passed vertically and left and right in the lower part. Flowing water can be performed quickly. In addition, since the legs 3 (the insertion portion of the artificial grass leaf piece 7) are scattered, the bundle of the artificial grass leaf pieces 7 is separated, so that the water retention can be reduced. Since there is a gap below the base 1 except for the legs 3, as shown in FIG. 3 and FIG. Since the lower part of the lawn imitation leaf piece 7 is inserted in a bundle shape, the lawn imitation leaf piece 7 compensates for deformation due to the movement of the leg 3, so that the lawn imitation leaf piece 7 is flexible, has excellent resilience, and can sufficiently withstand a load. That is, if the leg 3 is in a solid state, it is hard and has no flexibility, and if the leg 3 is in a hollow state, the leg 3 is easily deformed and bent or cannot withstand the frequent load. Since the lower part of the lawn imitation leaf piece 7 is inserted into the leg portion 3 in a bundle, the leg portion 3 itself has strength and elasticity, has excellent flexibility, and can sufficiently withstand the number of times of load. It becomes. Therefore, by the configuration of the base 1 having a moderate flexibility, the base 1 not only improves the durability but also serves as a cushion (relieve the burden) on the human body.
It is also excellent in usability.

Next, in the lawn imitation leaf piece 7, the leg 3
The lower part (root portion) of the lawn imitation leaf piece 7 can be formed long (deep) by inserting it in a bundle shape, and this has the effect of standing and restoring the lawn imitation leaf piece 7 itself, and the sustained lawn imitation leaf piece 7 Can be supported. Further, since the inserted root portion is a bundle of the lawn imitation leaf pieces 7, the impact is reduced by an external load, and the durability of the root portion is enhanced. or,
Since the lawn imitation leaf piece 7 is in a bundle form, when water is splashed by rainwater or watering in a bundle-shaped portion (near immediately above the root), it is possible to keep a minute moisture due to a capillary phenomenon, Gives moisturizing and suppleness to the lawn imitation leaf pieces 7, and in the summertime, this moisture helps cooling, and also, a bunch of flexible lawn imitation leaf pieces 7 covers the base 1. Base 1 is shaded,
The effect of reducing the deterioration and elasticity of the base 1 can also be obtained.

FIGS. 5 and 6 show another embodiment.
A cylindrical insertion opening 11 having an opening area larger than that of the leg 3 is provided between the leg 3 and the lower part of the artificial lawn leaf 7 so that the artificial lawn leaf 7 protrudes upward from the leg 3. Are inserted and fixed in a bundle from the insertion opening 11 into the leg 3. The other points are the same as the configuration of the embodiment. According to the configuration of the above embodiment, while having the operation and effects of the above embodiment shown in FIGS. 1 and 2, between the base 1 and the leg 3,
Since there is a cylindrical insertion opening 11 having an opening area larger than that of the leg portion 3, a gap A generated between the insertion opening 11 and the imitation grass piece 7 under the base 1 as shown in FIG. It functions as a space to reduce the load impact due to the stepping foot or the like.
Further, the restoration of the lawn imitation leaf piece 7 using the wall of the insertion opening 11, that is, the restoration of the lawn imitation leaf piece 7 can be achieved by being pushed. Further, since the tread surface is on the upper surface of the base 1 at a position away from the root of the lawn imitation leaf piece 7, the touch of only the soft part of the lawn imitation leaf piece 7 can be obtained without directly stepping on the clump of the lawn imitation leaf piece 7 in a bundle. It becomes more comfortable to use. In addition, since the load is applied only to the soft part, the load on the lawn imitation leaf piece 7 is reduced, and the durability is further improved.

FIGS. 8 to 10 show another embodiment, in which a number of water holes 2 are provided in a row on a base 1 and the base 1 is positioned above an installation surface 4 so that the base 1 is located above a mounting surface 4. A plurality of cylindrical legs 3 projecting downward are provided in a row at an interval from each other, and an insertion opening 11 having a larger opening area than the legs 3 is provided between the base 1 and the legs 3. The insertion opening 11 extends over the plurality of legs 3 arranged in a row. Legs 3 arranged in a row as shown in FIG.
A bottom wall 11a of the insertion port 11 is located at a position lower than the base 1 and the cylindrical leg 3 projects downward from the bottom wall 11a. In this case, as shown in FIG.
May be provided. The other points are the same as those of the embodiment shown in FIGS. 3 and 4. The lower part of the lawn imitation leaf piece 7 is inserted and fixed in a bundle from the insertion opening 11 into the leg 3. 3 and 4 have the same functions and effects as the embodiment of FIG.

FIG. 11 shows a modification of the embodiment shown in FIGS. 5 and 6, in which a grid piece 14 is provided in the water passage hole 2 of the base 1. The other points are substantially the same as those of the embodiment shown in FIGS. The method of attaching the lawn imitation leaf piece 7 to the leg 3 of the base 1 is as follows.
As shown in FIG. 12, a large number of lawn imitation leaf pieces 7 are bundled and arranged, and the bundle is pressed into the leg 3 by the metal fitting 17, and the metal fitting 17 is fitted inside the leg 3. As shown in FIGS. 13 and 14, a large number of bundled lawn imitation leaf pieces 7 are squeezed (clamped) at intervals with a wire 18 or the like, and the bundled lawn imitation leaf pieces 7 are cut along a dotted line portion. The wire 18 is pushed into the leg 3 and the wire 18 and the like are pushed into the leg 3.
Fit inside. As shown in FIG. 15 and FIG. 16, a large number of bundled lawn imitation leaf pieces 7 were fixed at intervals with an adhesive or heat fusion or the like, cut at a dotted line portion, and then fixed with an adhesive or heat fusion or the like. The portion is pushed into the leg 3, and the lower part of the lawn imitation leaf piece 7 is fixed to the leg 3 with the adhesive 19 or the like injected into the leg 3.

The imitation grass piece 7 may be a round bar as shown in FIG. 17 or a flat (plate) as shown in FIG. When the leaf piece 7 is a round bar or flat,
Even if they are bundled and tightened, each one easily moves in the longitudinal direction. The lawn imitation leaf piece 7 may be a twisted one as shown in FIG. In this case, if a plurality of bundles are bundled as shown in FIG. 20 and fastened with the metal fittings 20 or the like as shown in FIG. 21, each of them becomes difficult to move in the longitudinal direction, and as shown in FIG. When the bundle of the leaf pieces 7 is cut, the cut side is largely spread.
