Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an artificial lawn to be laid on rooftops, balconies, poolsides, entrance mats, walkways, grounds, etc.

(Prior Art) As shown in FIGS. 9 to 11, a conventional artificial lawn is made by bundling a plurality of leaf wires 12 on a thin fiber plain-woven base fabric as a lawn base 3 and sewing them densely in the vertical and horizontal directions with a sewing machine needle 11. The rope portion 13 of the sewn leaf wire material is pulled with the claw 24 and cut with the cutter 14 to form grass leaf pieces 4 planted at each seam,
A lawn base 2 made of foamed synthetic rubber is adhered to the lower surface side of a lawn base 3 on which leaf wire rods 12 are folded back.

(Problems to be solved by the invention) The above-mentioned conventional technology does not have drainage holes and does not take water drainage into consideration, so rainwater accumulates and does not dry, and it becomes discolored due to dirt and limescale, making it unsanitary. This reduces the durability of the turf base and turf base.

However, in the conventional structure of artificial lawns, even if drainage holes are provided, the lawn base is made of foamed synthetic rubber, which has water absorption properties, so water drainage cannot be improved, and the rigidity of the lawn is extremely low and varies greatly. The supporting force of the base was weakened, and it was difficult to form long leaflets.

(Means for Solving the Problems) The means taken by the present invention to solve the above-mentioned problems is to bundle a plurality of leaf wire rods 12 and sew them to the lawn base 3, and then sew the sewn leaves to the lawn base 3. Ru of wire rod 12
The grass leaf pieces 4 are formed by cutting the grass leaf pieces 13, and the lawn base 2 is placed on the lower surface of the lawn base 3 on which the grass leaf pieces 4 are planted.
In the artificial lawn formed by gluing together, the lawn base 3 is formed into a belt shape by planting one or more rows of lawn leaf pieces 4, and the lawn base 2 is made of a thick non-foaming elastic material. On the surface 5, a plurality of parallel rows of recessed fittings 6 for embedding the strip-shaped lawn base 3 are formed at intervals, and a large number of drainage holes penetrate vertically between each row of the recessed fittings 6. Holes 7 are arranged in rows, and a water channel 9 communicating with the drainage holes 7 is formed on the ground surface 8 of the lawn base 2.

(Function) The lawn base 2 of the artificial lawn 1 is made of a thick non-foamed elastic material, has relatively high rigidity, and can withstand loads from above without being deformed due to its elasticity. To support. In addition, the surface 5 of the lawn base 2
The recessed fitting portion 6 formed in the groove allows the lawn base 3 on which the grass blades 4 are planted to be buried, and also prevents positional wear.

Further, a large number of drainage holes 7 between the recessed parts 6 of the lawn base 2 drain rainwater downward, and a water channel 9 communicating with the drainage hole 7 of the ground surface 8 drains water from the drainage hole 7. Rainwater is further removed underground or to a lower location.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

1 to 5 show the first embodiment, and the artificial lawn 1A
is composed of a lawn base 2, a lawn base 3, and lawn leaf pieces 4.

The lawn base 2 is thickly formed of an elastic material such as rubber or synthetic resin that has a sufficiently higher rigidity than conventional foamed rigid rubber, is non-foamable, and has elasticity and shape retention. , a plurality of recessed fitting parts 6 are formed parallel to the lawn base 2 in rows at regular intervals on the surface 5, and the recessed fitting parts 6 extend from the side edge of the base 2 to the other side. It is formed up to the side edge of the recessed fitting part 6.
A row of drain holes penetrating in the vertical direction is formed between each row of. The drainage hole 7 has a rectangular opening when viewed from above, and its opening is reduced downward.

In addition, a water channel 9 and a horizontal water channel 9' are formed on the ground surface 8 of the lawn base 2, and the water channel 9 is formed parallel to and immediately below the row of drainage holes 7, and the drainage hole 6 in the vertical direction. The water channel 9 and the horizontal water channel 9 are orthogonally connected to each other, and the horizontal water channel 9' is orthogonally communicated to the water channel 9 at the position of the drainage hole 6 in the horizontal direction.

The lawn base 3 is made of rubber, synthetic resin, fiber plain-woven base fabric, or a layered material of the base fabric and rubber or synthetic resin, and the base material 10 is a large-area sheet-like material as shown in FIG. belongs to. The material 1
0 is one that can be inserted with a sewing machine needle, and its thickness is preferably approximately the same as the depth of the recessed fitting portion 6, but may be different.

The method of planting the lawn leaf pieces 4 is the same as the conventional method. That is, a plurality of leaf wires 12 made of thin wires made of synthetic resin such as nylon are bundled and sewn in rows to the base material 10 with a sewing machine needle 11, and the loops protruding from the seams on the upper surface are sewn into a bundle. -Cut the part 13 with the cutter 1.
4, and folded portion 1 of the leaf wire 12.
5 is adhered to the lower surface of the material 10.
Then, the raw material 10 is cut into each row (or multiple rows) of lawn leaves to form a strip-shaped lawn base 3 on which the lawn leaves 4 are planted. The lawn base 3 is the lawn base 2
It is embedded in the recessed fitting part 6 and bonded. The base 3 is firmly held by the recessed fitting portion 6, and positional wear of the base 3 is regulated. The deeper the recessed fitting part 6 is, the more firmly it holds the base 3, and the more reliable the position regulation becomes. Further, by increasing the thickness of the base 3 as the depth of the recessed fitting portion 6 increases, the supporting force of the grass blades can be increased, and the planting length of the grass blades 4 can be increased. As a result, the grass looks more like a natural lawn, and the sewing pitches can be made longer, making cleaning the leaf root part easier.

The artificial lawn 1A actually has a side of 30 cm, for example.
When installed on a laying surface, adjacent artificial lawns 1A are connected via connectors 16. In order to engage the connectors 16, long holes 17 are arranged in rows on at least both sides of the lawn base 2, and drainage holes 7 can be substituted for the other sides perpendicular to the both sides.

Incidentally, on the side edges of the elongated hole 17 and the drainage hole 7 that engage the connector 16, there are coupling engagements in order to make the upper and lower surfaces of the engaged connector 16 substantially flush with the lawn base 2. Preferably, the portion 18 is formed. Moreover, the long hole 1
The side waterway 19 communicating with 7 is connected to the ground surface 8 of the lawn base 2.
It is preferable to form it in advance.

FIG. 6 shows a second embodiment, in which the artificial lawn 13 has a cul-de-sac at both ends in the longitudinal direction of the recessed part 6 of the lawn base 2, and the drainage hole 7 is formed in a circle or an ellipse. The rest is substantially the same as the first embodiment.

Since both ends of the recessed fitting portion 6 in the longitudinal direction are shaped like a dead end, the position of the lawn base 3 in the longitudinal direction can also be regulated.

FIG. 7 shows a third embodiment, in which the recessed fitting part 6 of the lawn base 2 of the artificial lawn 1C is formed with a groove 21 sufficient to bury the folded part 15 between the seams of the leaf wire 12. , has a two-stage groove. By inserting the folded portion 15 into the groove 21, the lower surface 22 of the lawn base 3 comes into contact with the bottom surface 20 of the recessed fitting part 20 without floating, and therefore the lawn base 3 is prevented from sliding into the recessed fitting part 6. The burial becomes more compliant and the adhesion is more secure.

FIG. 8 shows a fourth embodiment, in which a groove 21 is provided in the recessed fitting part 6.
Instead, a lower groove 23 is formed in the lower surface 22 of the lawn base 3 to bury the folded portion 15 between the seams of the leaf wire 12. In this embodiment as well, the lower surface 22 of the base is brought into close contact with the bottom surface 20 of the recessed fitting part 6, and a good adhesion state can be obtained.

(Effects of the invention) According to the invention, since the lawn base 2 is made of a thick non-foamed elastic material, it does not absorb water and supports the load from above elastically and in a shape-retaining state. In addition, since the lawn base 2 is formed with a recessed fitting part 6 and the lawn base 3 on which the grass leaves 4 are planted is buried so as to fit the lawn base 3, the base 3 can be firmly held. The position of wear on the base 3 can be controlled.

Furthermore, since the lawn base 2 is formed with a drainage hole 7 that penetrates in the vertical direction and a water channel 9 that communicates with the drainage hole 7 on the ground surface 8 side, rainwater does not accumulate and washing is easy. Moreover, air circulation occurs and promotes drying, making it sanitary.
