Abstract

PURPOSE: To improve the bonding property of artificial turf with respect to the ground by using a number of small pieces as supports having imitation grass blades driven in place therebetween, and projecting the small pieces independently from a turf base. CONSTITUTION: Supports 8 to be buried in sand 4 together with a turf base 6 are projected upward from the turf base 6 and formed as a number of small pieces, which are independently projected from the turf base 6. Imitation grass blades 11 projecting upward from within the sand 4 are driven in place between the supports 8. Thereby integrality with the sand is improved and impacts on human bodies can be eased.

Description

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

(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 that spans approximately 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) Therefore, in the past, as shown in FIG. In this case, since each of the supports 2 had a long shape spanning almost the entire width, the sand 4 was finely divided by each of the supports 2, resulting in very poor adhesion to the ground. In addition, since the support 2 is in the form of a continuous long and narrow strip, external force loads received from sports etc. are transmitted to the entire length of the artificial lawn, making it difficult for the support 2 and the lawn imitation leaves 3 to flutter, thereby preventing, for example, a baseball from slipping. In such cases, the impact (impact) on the human body from the artificial turf will be extremely large. Furthermore, 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, there are problems such as restricting the rolling direction of the ball. occured.

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 this artificial lawn, the supporting body 8 is planted with grass imitation leaf pieces 11 that protrude upward from the sandy soil 4, and the supporting body 8 is formed into a large number of small pieces, each of which is independently protruded from the lawn substrate 6. It is in the point that it is.

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

(Example) Hereinafter, description will be made according to the illustrated example of the present invention.
In the drawings to FIG. 4, reference numeral 6 denotes a lawn substrate, which is made of a hard material such as hard vinyl chloride or ABS resin, or elastic rubber or resin such as urethane resin or vinyl acetate, and is made of a lattice-shaped substrate having a large number of openings 7. is formed.

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-back 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.

Reference numeral 11 denotes a lawn imitation leaf piece, which is embedded in each strip-shaped mounting body 12 so as to protrude upward 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. It is implanted on the support body 8 via the body 12.

5 to 11 show other embodiments, and the support 8
are respectively U-shaped, arcuate, triangular, square, circular, dogleg-shaped, or L-shaped small pieces, and this large number of supports 8
are independently protruding from a lawn substrate l (not shown) so as to be dotted with no directionality, and lawn imitation leaf pieces 11 are planted on each support 8 via a mounting body 12. It is. In addition, in the case of FIG. 7, FIG. 8, and FIG. 9, since the support body 8 is annular, the sandy soil 4 inside each support body 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 is continuous and integrated.

Incidentally, in the above embodiment, the lawn imitation leaf pieces 11 are planted on the support body 8 via the strip-shaped attachment body 12.
Alternatively, the attachment piece 12 may be omitted and the lawn imitation leaf piece 11 may be directly planted on the support body 8.

(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 support body 8 is buried can be made continuous over almost the entire area, so that 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, so the impact on the human body from artificial grass (
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 gnarled and non-directional lawn can be formed.

Therefore, when the artificial turf of the present invention is laid, it is possible to enjoy sports and the like very safely with few injuries, making it ideal as an artificial turf to be laid on grounds and the like. 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 upflow on slopes and the like.
