Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention provides a support body protruding upward from a lawn substrate.
This invention relates to an artificial lawn in which imitation lawn leaf pieces are planted.

(Prior art) For artificial lawns, as shown in FIGS. 12 and 13, a support 2 is provided on a lawn substrate 1 so as to protrude upward, and imitation lawn leaves 3 are attached to this support 2 to protrude upward from sandy soil.
However, in conventional artificial lawns of this type, the support 2 is in the form of a continuous long and thin strip spanning almost the entire length of the artificial lawn, and this support 2 is used as a lawn substrate. 1, a large number of them were protruded parallel to each other at equal intervals (for example, in the patent application filed in 1983-
81011).

(Problems to be Solved by the Invention) Conventionally, as shown in FIG. When protruding, each support 2 has a long shape that spans almost the entire width, so the sand 4 becomes finely divided by each support 2, resulting in very poor adhesion to the ground. . In addition, since the support body 2 is in the form of a continuous long and thin strip,
The external force load received from sports etc. is transmitted to the entire length of the lawn substrate, making it difficult for the support 2 and the lawn imitation leaf pieces 3 to flutter, and therefore, for example, in the case of a slippery baseball game, the human body is affected by the impact from the artificial lawn. The impact (shock) will also be very large. moreover,
Since the support 2 is in the form of a continuous strip, it tends to cause directional problems in the grass, and when it is installed on a ground for playing golf or other sports, it causes problems such as restricting the rolling direction of the ball. .

In view of the above-mentioned problems, it is an object of the present invention to provide an artificial lawn that has good adhesion to the ground and is ideal for sports and the like, which can effectively reduce the impact on the human body.

(Means for solving the problem) The technical means of the present invention to solve this technical problem is that the lawn substrate 6 is provided with a support 8 that is buried in the sand 4 together with the lawn substrate 6 and projects upward. In an artificial lawn in which imitation lawn leaf pieces 11 protruding upward from sandy soil 4 are planted on this support 8, the support 8 is formed into a large number of small pieces, and the lawn substrate 6 is
The reason is that each of them is independently protruding from the other.

(Function) The sandy soil 4 in which the lawn substrate 6 and the support body 8 are buried is no longer divided into small pieces by the support body 8, and the sandy soil 4 becomes continuous over substantially the entire area. In addition, the external force loads received from sports etc. are limited to a small local area of the support 2, and each support 8 can swing independently and separately as shown by the chain line in FIG. For example, when playing baseball, the impact on the human body from the artificial turf can be effectively alleviated and absorbed. moreover,
By making the directions of adjacent supports 8 different from each other, it becomes possible to easily eliminate the directionality of the lawn.

(Embodiment) The following will explain the illustrated embodiment of the present invention. In FIGS. 1 to 4, reference numeral 6 denotes a lawn substrate, which is made of a hard material such as hard vinyl chloride or ABS resin, or has elasticity. It is formed into a lattice shape having a large number of openings 7 made of rubber, urethane resin, resin such as vinyl acetate, or the like.

Reference numeral 8 denotes a support body integrally provided upwardly protruding from the lawn substrate 6, and the support body 8 is formed into a large number of short pieces, each of which is provided to protrude independently from the lawn substrate 6. There are two types of supports 8, one oriented in the front-rear direction and the other oriented in the left-right direction, and these are arranged alternately vertically and horizontally so that the support 8 has no directionality. Each support 8 is provided with a fitting groove 9 recessed downward from the upper end.

11 is a lawn imitation leaf piece, and each mounting body 12 in the form of a strip
It is buried in an upwardly protruding manner over its entire length. The mounting body 12 is made of a soft material such as soft vinyl chloride or rubber, and its lower part is fitted and fixed to the fitting groove 9 of each support body 8 via an adhesive or the like, whereby the lawn imitation leaf piece 11 is attached. Support body 8 via body 12
It is planted in.

5 to 11 each show other embodiments,
Each of the supports 8 is a U-shaped, arcuate, triangular, square, circular, doglegged, or L-shaped small piece, and this large number of supports 8 is a lawn substrate 1 (not shown).
Lawn imitation leaves 11 are provided on each support 8 so as to be scattered independently so as to have no directionality.
is installed via a mounting body 12. In addition, in the case of FIG. 7, FIG. 8, and FIG. 9, since the support 8 is annular, the sand 4 inside each support 8 is separated from the others. However, the sand 4 between the supports 8 is continuous over the entire area, and therefore most of the sand 4 in which the supports 8 are buried becomes continuous and integrated.

Incidentally, in the above embodiment, the lawn imitation leaf pieces 11 are planted on the support body 8 through the strip-shaped attachment body 12, but instead of this, the attachment pieces 12 are omitted and the lawn imitation leaves are planted on the support body 8. The imitation leaf pieces 11 may be directly planted.

(Effects of the Invention) According to the present invention, the support 8 on which the lawn imitation leaf pieces 11 are planted is formed into a large number of small pieces, each of which is independently protruded from the lawn substrate 6. The sandy soil 4 in which the supports 8 are buried can be made continuous over almost the entire area, and therefore the artificial lawn of the present invention has good integrity with the sandy soil 4 and has very good adhesion to the ground. In addition, the transmission of external force loads received during sports, etc. is limited to only a partial range of one support 8, and since each support 8 is a small piece, it tends to fluctuate greatly, which reduces the impact on the human body from artificial turf. (impact) can be sufficiently alleviated.

Furthermore, since the supports 8 are formed into small pieces, by making the directions of adjacent supports 8 different from each other, a non-directional lawn can be easily formed.

Therefore, when the artificial lawn of the present invention is laid,
It is an extremely safe way to enjoy sports with fewer injuries, and is ideal as an artificial lawn for laying on grounds, etc. In addition, as another use, it has good integrity with the sand 4, can handle loads from up, down, left and right directions, and can be effectively used to prevent soil from drifting on slopes and the like.
