Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lawn protection material, and more particularly, to a lawn protection material made of synthetic resin for protecting lawn from being pressed against shoes or wheels.

[0002]

2. Description of the Related Art In lawn vegetation such as golf courses and parks, the lawn soil structure is protected from heavy treading pressure.
BACKGROUND ART For the purpose of protecting the lawn itself from external force, a lawn protection material having a large number of hollow cylindrical pressure-receiving parts at intersections of a lattice or hexagonal base has been used.

[0003]

However, in the conventional lawn protection material, since the pressure receiving portion is cylindrical, the volume of the protection material occupying the soil is large, and the amount of soil required for the lawn decreases accordingly. .
Moreover, it becomes a physical hindrance to the elongation of the root system of the lawn, which is not preferable for growing a healthy lawn.

Further, the lawn protection material of the type buried in the soil is based on the principle that the pressure receiving portion receives the treading pressure applied to the lawn instead of the lawn. Therefore, it is necessary to push the lawn pieces from the top of the pressure receiving portion to the lower surface with pressure of a roller or the like. At this time, the lawn sandwiched between the roller and the top surface of the pressure receiving portion will die.

Further, since the upper surface of the pressure receiving portion is exposed on the lawn to receive the stepping pressure, the larger the upper surface of the pressure receiving portion, the more the view of the turf cloth is damaged.

Accordingly, an object of the present invention is to provide a lawn protection material that can grow a lawn in a healthy state and does not impair the landscape.

[0007]

In order to achieve the above object, a lawn protection material according to the present invention combines a pressure receiving portion of a lawn protection material with a plurality of flat plates vertically erected on a substrate, The present invention is characterized in that the crossing portion is formed in a shape open toward the external space, and further, a columnar thick portion is provided in a part of the flat plate.

[0008]

FIG. 1 is a perspective view showing one embodiment of a lawn protection material of the present invention. The lawn protection material 10 is formed by combining three flat plates 12a, 12b, and 12c which are vertically erected on the upper surface of a square substrate 11 to form an H-shaped pressure receiving portion 13 in plan view. Each flat plate 12a, 12
Each of the intersections C of b and 12c is formed in a shape that opens toward the external space, so that a closed space is not formed. Also, three flat plates 12a, 12b, 12
c, two flat plates 12a and 12 on both sides with side edges exposed.
On both side edges of b, columnar thick portions 14 for improving the strength of the end portions are provided in the vertical direction, respectively.

From the center of the four sides of the substrate 11, connecting pieces 15 for connecting the lawn protection members extend in all directions. The base of the connecting piece 15 is formed in a shape extending from the upper surface of the substrate 11 to the side surface of each of the flat plates 12a, 12b, and 12c, and the leading end can reliably perform positioning when connecting the connecting pieces 15 to each other. As described above, the thin portion 15a whose predetermined direction is cut is formed.

As shown in the plan view of FIG. 2, the lawn protection member 10 is provided with the connecting piece 15 of the adjacent lawn protection member 10.
The thin portions 15a are overlapped and connected by a joining method such as heat welding, so that the entire portion has an appropriate size, for example, 30c.
Assembled in m-square. Alternatively, it is integrally formed in a state where a plurality of lawn protection members 10 are combined. The direction in which the lawn protection members 10 are connected is arbitrary, and may be all aligned in the same direction, or may be connected in different directions as shown in FIG. Also, since the shape was such that a space was formed below the connecting piece 15 during connection,
The connecting piece 15 does not hinder the elongation of the lawn root system.

As described above, the pressure receiving portion 13 of the lawn protection material 10 is formed by a plurality of flat plates 12a, 1
2b and 12c, and each flat plate 12
By forming the crossing portion C of a, 12b, and 12c in an open shape toward the external space, the volume of the pressure receiving portion 13 can be reduced, and the area of the upper surface of the pressure receiving portion 13 can be reduced. . As a result, the ratio of the lawn protection material 10 in the soil is reduced, and the lawn can be grown in a healthy state. Further, the area of the upper surface of the pressure receiving portion 13 is also reduced, and the lawn sandwiched between the rollers is reduced. Not only is minimized, but also the pressure receiving portion 13 becomes inconspicuous, so that the scenery of the turf is not spoiled.

FIG. 3 is a perspective view showing another embodiment of the lawn protection material of the present invention. The lawn protection member 20 has a pressure receiving portion 23 in which two flat plates 22a and 22b are combined in a cross shape on the upper surface of a disk-shaped substrate 21, and an intersection C between both flat plates 22a and 22b is formed. , And is open to the outside space, so that no closed space is formed. A column-shaped thick portion 24 for improving strength is provided on each side edge of both flat plates 22a and 22b.

Further, from the side edges of the flat plates 22a and 22b, connecting pieces 25 similar to the above extend in all directions, and the lawn protection member 20 is connected to each connecting piece 2 as shown in the plan view of FIG.
5 are connected to form an appropriate size.

In the lawn protection member 20 having such a shape, the pressure receiving portion 23 has a small volume, and the area of the upper surface thereof is also significantly reduced. And the lawn caught between the rollers is minimized, so that the scenery of the lawn is not impaired.

The shape of the substrate or the flat plate erected on the substrate can be arbitrarily formed according to the required strength and the like, and the shape of the connecting piece is not limited to the shape of the above embodiment. Absent. Further, pressure receiving portions having different shapes can be connected.

[0016]

As described above, according to the lawn protection material of the present invention, the volume of the pressure receiving portion is reduced and the ratio of the pressure receiving portion to the soil is reduced, so that the lawn can be grown in a healthy state. At the same time, the area of the upper surface is greatly reduced, so that the lawn sandwiched between the rollers is minimized, and the landscape of the lawn fabric is not impaired.
