Description

[Detailed Description of the Invention] This invention relates to an artificial lawn periphery presser for pressing down the periphery of an artificial lawn laid on a foundation layer.

Generally, when constructing an athletic field such as a tennis court using artificial turf, a flat foundation layer is formed, and the artificial turf is laid on top of that foundation layer, and along the periphery of the artificial turf is laid down. Forming a drainage ditch and inserting the periphery of artificial grass into the drainage ditch,
In addition, the periphery of the drain is held down by the drain cover. The reason for doing this is to guide rainwater etc. from the lawn surface to the drainage ditch and to prevent the edges of the lawn from rolling up. However, on the other hand, this also means that the edges of the artificial lawn are always kept in a moist atmosphere. Since it is exposed and pressed by the drain cover, there is a disadvantage that its periphery is damaged early. On the other hand, when laying artificial turf on an existing concrete foundation such as on a rooftop site, it is difficult to form drainage ditches as described above, so it is necessary to prevent the surrounding edges from rolling up. In a sand-containing artificial lawn in which sand is filled into the grains of the artificial lawn, an appropriate holding member is required to prevent the sand from flowing out from the periphery.

Therefore, this invention provides a periphery presser for artificial turf that can effectively prevent rolling up of the periphery of artificial turf and sand runoff, and is equipped with drainage ditches for rainwater, etc., and is easy to structure and handle. It is about providing.

Hereinafter, this invention will be described in detail with reference to embodiments shown in the accompanying drawings.

This holding tool 1 is arranged along the periphery of an artificial lawn 3 laid on a flat foundation layer 2 made of, for example, concrete, and is substantially in surface contact with the foundation layer 2, for example. It comprises a base plate 4 having a flat bottom surface and a main body 5 integrally formed on the base plate 4, and is made of, for example, hard plastic, aluminum alloy, or other suitable hard material. In this case, the main body 5 has a substantially triangular cross section, and the artificial lawn 3
The front surface 6 with respect to the peripheral edge is formed in a concave shape as shown in the figure, and on the lower surface side of the main body portion 5,
A plurality of drain grooves 7 extending from the front surface 6 side toward the rear are provided at appropriate intervals. In this embodiment, the front surface 6 of the main body portion 5 is formed in a concave shape, but it may be a groove having a U-shaped cross section, for example, and in short, it is a gutter formed to receive the periphery of the artificial lawn 3. Any shape recess may be used.

When the artificial lawn 3 is laid, its peripheral edge is inserted into a gutter-like recess formed in the front surface 6 of the main body part 5. Therefore, bending, curling up, etc. of the periphery of the flexible artificial lawn 3 is prevented, and
In the case of an artificial lawn with grass, sand is prevented from flowing out, and rainwater and the like on the surface of the lawn are drained through a drainage groove 7 formed in the main body part 5. It goes without saying that the base plate 4 of the presser 1 may be fixed onto the base layer 2 using an adhesive or the like, if necessary. In the above embodiment, the drain groove 7 is provided on the lower surface side of the main body portion 5, but this may be a drain hole 8 as shown in FIG. 2.

As is clear from the description of the embodiments described above, according to this invention, it is possible to effectively prevent the edges of the artificial lawn from rolling up and sand to flow out, and the artificial lawn is equipped with drainage channels for draining rainwater, etc. A peripheral retainer is provided.
