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 suitable for protecting lawn and the like from pressure contact with shoes and wheels and growing the lawn.

[0002]

2. Description of the Related Art Lawns have conventionally been created in various places as simple green spaces that provide comfort to urban spaces, and the action of purifying air pollution by photosynthesis has also been evaluated. Furthermore, in recent years, with the development of non-permeable concrete pavements in urban areas, new problems such as the occurrence of floods and the depletion of groundwater sources have arisen. One of the solutions to such problems is water retention and permeability. Excellent lawn utility is being re-evaluated.

[0003] Lawns are bred so that each lawn is spread by an underground stalk called a runner to cover the ground. It is important to secure the structure of the upper soil and to improve drainage. However, lawns are constantly trimmed short and often under the adverse conditions of being frequently trampled by heavy objects such as people and automobiles. Is difficult.

[0004] For this reason, in lawn vegetation such as golf courses and parks, the purpose of protecting the lawn's upper limb structure from the pressure of heavy objects and protecting the lawn itself from external force is as follows.
A lawn protection material provided with a large number of pressure receiving members at each intersection of the vertical and horizontal lattices is used (see Registered Design No. 706520). This lawn protection material is intended to protect the lawn by connecting a number of connecting parts provided on the outer periphery of the lawn protection material, and the lawn protection material is roughly divided into mats that are simply laid on the surface of the lawn. There are a block type and a block type in which lawns are planted on the soil surface in the gap between the pressure receiving bodies by increasing the pressure receiving bodies.

[0005]

However, in the conventional lawn protection material, the lower edge of the pressure receiving body and the lower edge of the connecting portion are formed flush with each other, so that the runner of the lawn is under the lawn protection material. It could not be deployed through the side, which hindered the growth of the lawn.

Also, when connecting lawn protection materials,
It is necessary to simultaneously connect a plurality of connecting portions provided on the side of the lawn protection material, but the positioning is troublesome.

Accordingly, an object of the present invention is to provide a lawn protection material that does not hinder the deployment of lawn runners and that can easily connect lawn protection materials.

[0008]

In order to achieve the above object, a lawn protection material according to the present invention comprises a synthetic resin lawn protection member formed by connecting a large number of pressure receiving members receiving tread pressure at connecting portions to form a lattice. The material is characterized in that a lower edge of the connecting portion is located above a lower edge of the pressure receiving body.

Further, the lawn protection material of the present invention is formed by connecting a plurality of pressure receiving bodies receiving treading pressure at connecting portions to form a lattice shape, and connecting a male connecting portion for connection on the side and the male connecting portion. A female connecting portion provided with a female connecting portion, wherein the female connecting portion is formed in a cylindrical shape having a slit through which the male connecting portion can be inserted in a vertical direction, and the male connecting portion is formed. The upper end or the lower end of the engagement portion that enters the cylindrical portion of the female connection portion is provided with an engagement projection that engages with the upper edge or the lower edge of the cylindrical portion of the female connection portion. A guide portion for guiding both connecting portions to a predetermined position at the time of connection is provided above the unit side engaging protrusion and below the lower end side engaging protrusion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a plan view showing an embodiment of a lawn protection material according to the present invention, in which a central portion is omitted, FIG. 2 is a front view of a main part, and FIG. FIG. 4 is a perspective view of the male connecting portion.

First, as shown in FIG. 1 and FIG. 2, this lawn protection material comprises the same number of hollow square truncated pyramid-shaped pressure-receiving members 1 arranged at equal intervals in the vertical and horizontal directions by a connecting portion 2. It is formed in a square shape, and on each side, a male connecting portion 3 and a female connecting portion 4 for connecting the lawn protection materials at the time of laying are provided at point symmetric positions with respect to the lawn protection material center point. Have been.

As shown in FIG. 2, the connecting portion 2 has an upper edge 2a at a position approximately half the height of the pressure receiving member 1 and a lower edge 2b.
Are formed slightly above the lower edge of the pressure receiver 1. That is, the connecting portion 2 between the adjacent pressure receiving bodies 1
The lower edge 2b is cut out to form an opening 5 large enough to allow the lawn runner to be deployed.

With this arrangement, when the lawn protection material is laid on the lawn, the pressure receiving body 1 can avoid the influence of frequent stepping pressure due to heavy objects, and the lawn runner can be connected to the lower opening 5 of the lawn protection material. Because it can be deployed through, there is no hindrance to the growth of the lawn.

The male connecting part 3 and the female connecting part 4 are
The male connecting portions 3 connect the lawn protection members by engaging with each other. The male connecting portion 3 includes a connecting portion 31 connected to the lawn protecting material, and a substantially U-shaped planar view provided at the tip of the connecting portion 31. And an engagement portion 32 in a shape of a circle. One female connection 4
Has a cylindrical engaging groove 41 through which the engaging portion 32 of the male connecting portion 3 can be inserted vertically.
A slit 42 for vertically inserting the connecting portion 31 of the male connecting portion 3 is provided at the distal end of the male connecting portion 3.

Further, engaging projections 33a and 33b for engaging with the engaging grooves 41 of the female connecting portion 4 are provided on the outer surfaces of both wing sides of the engaging portion 32 of the male connecting portion 3, respectively.
One engaging projection 33a is provided at the upper end of the outer side surface of the wing and engages with an engaging step 43a provided at the upper edge of the engaging groove 41 of the female connecting part 4, while the other engaging projection 33b Is engaged with an engaging step 43b provided at the lower end of the outer side surface of the wing side and provided at the lower edge of the engaging groove 41 of the female connecting portion 4, whereby the connecting portions 3 and 4 are engaged. Is maintained.

A guide portion 34 for guiding the connecting portions 3 and 4 to a predetermined position when connecting the connecting portions 3 and 4 is provided above or below the engaging projections 33a and 33b.
a and 34b are provided respectively. This guide part 3
4a and 34b are portions where the two connecting portions 3 and 4 come into contact first when the two connecting portions 3 and 4 are connected, and the positioning of the two connecting portions 3 and 4 at the time of connection becomes easy, and this embodiment In the example, the engagement and connection work of the connection portions 3 and 4 at four locations on one side can be easily performed. In particular, by forming the guide portions 34a and 34b to be thin and smaller than the width dimension of the engagement groove portion 41 of the female connecting portion 4, the guiding effect of the connecting portions 3 and 4 can be further improved.

[0017]

As described above, according to the lawn protection material of the present invention, it is possible to easily connect the lawn protection materials without hindering the deployment of the lawn runner.
