DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial turf which is laid particularly on natural undulating terrain, sloping terrain, soft terrain, or a narrow place or small space.

[0002]

2. Description of the Related Art As a conventional artificial lawn, as shown in FIG. 22, there is a lawn in which a large number of lawn imitation leaf pieces 22 are projected upward on a plate-like base 21 (for example, Japanese Patent Publication No. 54-18853). As another conventional artificial turf, as shown in FIG. 23, a plurality of rows of projecting mounting portions 26 are provided on a base 25 made of a net material. There is one in which the imitation leaf piece 27 is attached so as to protrude upward.

[0003]

However, in the conventional case,
In the former, the lawn imitation leaf piece 22 is established under the pressure of the soil 28 and the purpose is to keep the lawn imitation leaf piece 22 vertical even when laid on a slope, which means that the lawn is imposed by the pressure of the soil 28. Since the imitation leaf pieces 22 are established and maintained, when the pressure of the soil 28 fluctuates, so-called stepping pressure load or runoff due to rainwater, etc., the lawn imitation leaf pieces 22 are immediately formed.
There was an inconvenience that the plant fell down and lost the function of the artificial grass.

In the latter case, the row-like projection-like mounting portions 26 are provided.
Because the belt-like lawn imitation leaf piece 27 is attached to the
The base 25 is easy to bend in a direction orthogonal to the row direction of the protrusion-like mounting portions 26, but is hardly bent in the row direction of the protrusion-like mounting portions 26, that is, in the band direction of the lawn imitation leaf piece 27. Since the mounting portion 26 and the lawn imitation leaf piece 27 are configured in a row or a band shape, the soil layer is separated in the row or band direction, and the adhesive strength of the soil is not obtained,
There were inconveniences such as poor fixation of artificial grass.

[0005] In view of the above problems, the present invention can be laid on a rough or sloping land in a state where it can be easily adapted to the ground and makes use of its natural shape, and can firmly settle the lawn imitation leaf pieces without disturbing them. , Or when laid on soft ground,
Ground fluctuations can be suppressed to stabilize the lawn-imitation leaf pieces, and similarly stable laying can be obtained even in narrow places and small spaces.

[0006]

Means for Solving the Problems A first technical means of the present invention for solving this technical problem is an artificial turf having a large number of simulated lawn leaf pieces 6 protruding upward from a base 1, wherein the base 1 has a net shape. At the intersection 4 of the base 1 so as to protrude upward so that the bundle 7 of the lawn imitation leaf pieces 6 is established.

A second technical means of the present invention resides in that the root portion of the bundle of the lawn imitation leaf pieces 6 is tied to the intersection 4 of the base 1. The third technical means of the present invention is that the base 1
Has flexibility. A fourth technical means of the present invention resides in that a base cloth 15 is provided along the base 1.

Therefore, even when artificial grass is laid on the uneven ground, the bundle 7 of the lawn imitation leaf pieces 6 is scattered and self-standing at the intersection 4 of the base 1 alone. Lawn imitation leaf piece 6 self-standing according to the inclination of 4
Bunch 7 can always protrude from the base 1 at right angles, and the bundle 7 of the lawn imitation leaf pieces 6 provides shear resistance against lateral displacement, and the bundle 7 of the lawn imitation leaf pieces 6 alone at the intersection 4 In addition, since the surrounding soil is not cut off by being arranged in a dotted manner, the adhesive force of the soil is not impaired, and the lateral displacement of the net-like base 1 can be effectively prevented. it can. Also, the bundle 7 of the lawn imitation leaf pieces 6
Because it is supple and established in tension,
The soil entangled in the lawn imitation leaf pieces 6 can be more firmly established.

Further, in small places and small spaces, etc., only the net-like base 1 has a small supporting force and lacks fixing ability.
By providing not only the supporting force of the net-shaped base 1 but also the shear resistance in the lateral direction by the bundle 7 of the lawn imitation leaf pieces 6, a stable laying can be always obtained under any circumstances. The net-shaped base 1 may be deformed due to the movement of the position of the intersection 4, but since it does not wrinkle like a plate-shaped base, it fits on uneven ground and the lawn imitation leaf piece 6 is Since it is established at the intersection 4, it is possible to maintain a stable artificial turf without disturbing the establishment of the lawn imitation leaf piece 6.

Further, by mounting the base cloth 15 on the base 1, weeds can be prevented from growing.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. 1 to 3, 1 is a base,
A large number of first linear bodies 2 which are made of a synthetic resin, rubber or metal material and the like which are rich in flexibility, elasticity and flexibility, and which are arranged in parallel at equal intervals with each other; A large number of the second linear bodies 3 are arranged so as to be orthogonal to each other, and the first linear bodies 2 and the second linear bodies 3 are connected and fixed to each other at each intersection 4. It is formed in a net shape, that is, a net shape having a square mesh.

The bundle 7 of the lawn imitation leaf pieces 6 is fixed to each intersection 4 of the base 1, and the lawn imitation leaf piece 6 is established from each intersection 4 of the base 1. The lawn imitation leaf piece 6 is formed of a synthetic resin such as a nylon thread or a polypropylene thread. The lawn imitation leaf pieces 6 are bundled into several bundles, wound at the center in the longitudinal direction of the bundle of lawn imitation leaf pieces 6 so as to be engaged with the intersection 4 from below, and protruded upward. Bundle of 6 7
The upper side of the winding portion 8 is strongly caulked by a ring 9 made of wire or the like, and the bundle 7 of the lawn imitation leaf pieces 6 is fixed to the intersection 4.

In this manner, the upper part (root part) of the winding part 8 of the bundle 7 of the lawn imitation leaf pieces 6 is fastened in a bundle by the ring 9, and the root part of the bundle 7 of the lawn imitation leaf pieces 6 intersects the base 1. Tied up against part 4, which causes each intersection 4
Each of the bundles 7 of the lawn imitation leaf pieces 6 is independently scattered and self-standing. Then, a bundle 7 of imitation lawn leaf pieces 6 having self-standing according to the inclination of each intersection 4 of the base 1
Always project from the base 1 at right angles.

According to the above-described embodiment, the bundle 7 of the lawn imitation leaf pieces 6 is singly scattered and self-standing at each of the intersections 4 of the base 1, as shown in FIG. 6 and 9, even when artificial grass is laid on the uneven ground, the bundle 7 of the lawn imitation leaf pieces 6 having self-standing according to the inclination of the intersection 4 of the base 1 is always the base 1.
At right angles. This is because even if the lawn imitation leaf piece 6 is flexible, the self-standing of the lawn imitation leaf piece 6 can be obtained by binding the root of the bundle 7 of the lawn imitation leaf piece 6 to the intersection 4 of the base 1. .

Originally, if only the net-shaped base 1 is provided, as shown in FIG. 7, the base 1 is installed on a flat ground, and the ground 1 has a large number of ground planes formed by the linear bodies 2 and 3. If this is buried in the soil, the net-like base 1
However, since the base 1 has a small thickness in the vertical direction, the base 1 lacks a so-called shearing resistance against displacement in the lateral direction. For example, as shown in FIG. When a load greater than the support capacity of the base 1 itself or a load on soft ground is received, the load-receiving portion of the base 1 is pushed downward, and the surrounding net-like base 1 is Although it is inconvenient to be easily pulled toward the base, in the above-described embodiment, the root of the bundle 7 of the lawn imitation leaf pieces 6 is tied to the intersection 4 of the base 1, and the bundle 7 of the lawn imitation leaf pieces 6 is used as the base. 1 is self-standing at a right angle to the intersection 4, so that the bundle 7 of the lawn imitation leaf pieces 6 provides shear resistance against lateral displacement, and the bundle 7 of the lawn imitation leaf pieces 6 alone at the intersection 4. In addition, the surrounding soil is To not to cut, adhesive force is not impaired with the soil, it is possible to prevent the deviation in the lateral direction of the net-like base 1 effectively. Moreover, since the bundle 7 of the lawn imitation leaf pieces 6 is supple and is established in a tension state, the soil entangled in the lawn imitation leaf piece 6 can be more firmly settled.

In particular, when the net-shaped base 1 is deformed and cut or cut out, or in a small place or small space, only the net-shaped base 1 has a small supporting force and lacks fixability. Not only the bearing capacity of the shape base 1,
By providing the shear resistance in the horizontal direction by the bundle 7 of the lawn imitation leaf pieces 6, stable laying can be always obtained under any circumstances.

When an artificial turf having a plate-like base 21 is laid on uneven ground as shown in FIG. 24, wrinkles are generated on the plate-like base 21. In this case, although the position of the intersection 4 may move and deform as shown in FIG. 4, the portions of the linear bodies 2 and 3 may bend, and the net-shaped base 1 may be adapted to the uneven ground and wrinkled. As shown in FIGS. 5 and 6, the lawn imitation leaf piece 6 is established at the intersection 4 as shown in FIG. 5 and FIG. 6, so that the position of the intersection 4 to the lawn imitation leaf piece 6 is shifted even if the lawn is moved. The stable artificial grass can be maintained without affecting the establishment at all and without causing disturbance in the lawn imitation leaf piece 6.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the illustrated embodiments. 1 to 3, 1 is a base,
A large number of first linear bodies 2 which are made of a synthetic resin, rubber or metal material and the like which are rich in flexibility, elasticity and flexibility, and which are arranged in parallel at equal intervals with each other; A large number of the second linear bodies 3 are arranged so as to be orthogonal to each other, and the first linear bodies 2 and the second linear bodies 3 are connected and fixed to each other at each intersection 4. It is formed in a net shape, that is, a net shape having a square mesh.

The bundle 7 of the lawn imitation leaf pieces 6 is fixed to each intersection 4 of the base 1, and the lawn imitation leaf piece 6 is established from each intersection 4 of the base 1. The lawn imitation leaf piece 6 is formed of a synthetic resin such as a nylon thread or a polypropylene thread. The lawn imitation leaf pieces 6 are bundled into several bundles, wound at the center in the longitudinal direction of the bundle of lawn imitation leaf pieces 6 so as to be engaged with the intersection 4 from below, and protruded upward. Bundle of 6 7
The upper side of the winding portion 8 is strongly caulked by a ring 9 made of wire or the like, and the bundle 7 of the lawn imitation leaf pieces 6 is fixed to the intersection 4.

In this way, the upper part (root part) of the winding part 8 of the bundle 7 of the lawn imitation leaf pieces 6 is fastened in a bundle by the ring 9, and the root part of the bundle 7 of the lawn imitation leaf pieces 6 intersects the base 1. Tied up against part 4, which causes each intersection 4
Each of the bundles 7 of the lawn imitation leaf pieces 6 is independently scattered and self-standing. Then, a bundle 7 of imitation lawn leaf pieces 6 having self-standing according to the inclination of each intersection 4 of the base 1
Always project from the base 1 at right angles.

According to the above-described embodiment, the bundle 7 of the lawn imitation leaf pieces 6 is singly scattered and self-standing at each of the intersections 4 of the base 1, as shown in FIG. 6 and 9, even when artificial grass is laid on the uneven ground, the bundle 7 of the lawn imitation leaf pieces 6 having self-standing according to the inclination of the intersection 4 of the base 1 is always the base 1.
At right angles. This is because even if the lawn imitation leaf piece 6 is flexible, the self-standing of the lawn imitation leaf piece 6 can be obtained by binding the root of the bundle 7 of the lawn imitation leaf piece 6 to the intersection 4 of the base 1. .

Originally, if only the net-shaped base 1 is provided, as shown in FIG. 7, an example in which the base 1 is installed on a flat ground, the ground 1 has a large number of ground planes formed by the linear bodies 2 and 3. If this is buried in the soil, the net-like base 1
However, since the base 1 has a small thickness in the vertical direction, the base 1 lacks a so-called shearing resistance against displacement in the lateral direction. For example, as shown in FIG. When a load greater than the support capacity of the base 1 itself or a load on soft ground is received, the load-receiving portion of the base 1 is pushed downward, and the surrounding net-like base 1 is Although it is inconvenient to be easily pulled toward the base, in the above-described embodiment, the root of the bundle 7 of the lawn imitation leaf pieces 6 is tied to the intersection 4 of the base 1, and the bundle 7 of the lawn imitation leaf pieces 6 is used as the base. 1 is self-standing at a right angle to the intersection 4, so that the bundle 7 of the lawn imitation leaf pieces 6 provides shear resistance against lateral displacement, and the bundle 7 of the lawn imitation leaf pieces 6 alone at the intersection 4. In addition, the surrounding soil is To not to cut, adhesive force is not impaired with the soil, it is possible to prevent the deviation in the lateral direction of the net-like base 1 effectively. Moreover, since the bundle 7 of the lawn imitation leaf pieces 6 is supple and is established in a tension state, the soil entangled in the lawn imitation leaf piece 6 can be more firmly settled.

In particular, when the net-shaped base 1 is deformed and cut or cut out, or in a small place or small space, only the net-shaped base 1 has a small supporting force and lacks fixability. Not only the bearing capacity of the shape base 1,
By providing the shear resistance in the horizontal direction by the bundle 7 of the lawn imitation leaf pieces 6, stable laying can be always obtained under any circumstances.

When an artificial lawn having a plate-like base 21 is laid on uneven ground as shown in FIG. 24, wrinkles are generated on the plate-like base 21. In this case, although the position of the intersection 4 may move and deform as shown in FIG. 4, the portions of the linear bodies 2 and 3 may bend, and the net-shaped base 1 may be adapted to the uneven ground and wrinkled. As shown in FIGS. 5 and 6, the lawn imitation leaf piece 6 is established at the intersection 4 as shown in FIG. 5 and FIG. 6, so that the position of the intersection 4 to the lawn imitation leaf piece 6 is shifted even if the lawn is moved. The stable artificial grass can be maintained without affecting the establishment at all and without causing disturbance in the lawn imitation leaf piece 6.

FIGS. 10 to 18 show intersections 4 of the base 1 respectively.
5 shows another method of fixing the bundle 7 of the lawn imitation leaf pieces 6. FIG. 10 shows a configuration in which the ring 9 is made of a plate-like metal having a slightly wide width in the vertical direction, and the upper side of the winding portion 8 of the bundle 7 of the lawn imitation leaf pieces 6 is strongly caulked by the ring 9. FIG. 11 shows a lawn imitation leaf piece 6 at the intersection 4 of the base 1.
Of the lawn imitation leaf pieces 6 with the ring 9
Are crimped up and down at the intersection 4 in the longitudinal direction. In this case, if necessary, after caulking with the ring 9, heat setting may be performed immediately above the ring 9. FIG.
Puts a bunch of lawn imitation leaf pieces 6 on the intersection 4 of the base 1, crimps the longitudinal center of the bunch 7 of lawn imitation leaf pieces 6 up and down on the intersection 4 with a ring 9, and Of the bundle 7 is caulked with another ring 9 and bundled. FIG. 13 shows that a concave portion 11 is provided at the intersection 4 of the base 1, and the bundle of the lawn imitation leaf pieces 6 is bent in two at the central portion in the longitudinal direction, and the bent portion is inserted into the concave portion 11 so as to be made of metal, adhesive or This is fixed by heat deposition or the like.
