Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an artificial lawn for forming a lawn structure in which a natural lawn and an artificial lawn coexist.

Nowadays, artificial stems are used for baseball fields, soccer fields, tennis courts,
It is widely used for sports purposes such as golf teeing grounds, public spaces such as schools and parks, and even household balconies and terraces, expanding into the field of conventional natural grass.

However, the functions possessed by artificial lawns have both advantages and disadvantages, and the excellent functions possessed by natural lawns, such as water permeability,
It is inferior in terms of heat protection and cushioning properties. Furthermore, when laying artificial lawns, they are usually glued to a base such as concrete or asphalt, and it is not easy to install or remove them when replacing them.

On the other hand, natural grass also has problems in terms of durability and maintenance.
When various competitions are held on this grass, it is easily damaged by snow (e.g. shoes, golf clubs, etc.), and it takes a long time to restore it.In addition, in the winter, it is natural that the grass dries up, causing damage. Its appearance changes and many do not maintain their original green color.

The present invention aims to compensate for the disadvantages of both of these, and to utilize the advantages synergistically.

As a method of sharing an artificial lawn and a natural lawn, a method has already been proposed in Japanese Patent Publication No. 53-12742 in which the / , a method is disclosed in which soil is placed on top of the pile paper mount.The essence of this method is to utilize the property that the pile paper mount rots and disappears due to the action of water and moisture.This method is based on the above-mentioned artificial By laying and leaving the grass at the site where it will be used, the mount metal rots and disappears, allowing the remaining artificial grass pile to coexist with the natural grass that has grown over time.However, with this method, it is difficult to maintain the base of the artificial grass pile. Artificial grass has the disadvantage that it is extremely unstable and easily comes off when exposed to the action of snow shoes or golf clubs, making it virtually impossible to apply it to sports. The aspect is very limited.

The artificial lawn provided by the present invention is an artificial lawn made by planting fiber groups on a base fabric that is water resistant and corrosion resistant.
A plurality of voids are formed in order to allow the entire natural grass to grow on the base fabric, and the area ratio of the entire voids to the entire non-voided portions is 20.
It has a configuration in which it is distributed and provided so as to correspond to ~80 inches.

The base fabric having water resistance and corrosion resistance may be a base fabric made of natural or synthetic fibers, and a fiber group, that is, an artificial grass pile, may be planted thereon by knitting, kneading, electrodeposition, tufting, etc. have As a result, there is no fear that the base fabric will be lost due to water or moisture, and the artificial grass pile can be firmly held.

The size of the void portion is preferably such that the maximum area is 25 crI. The lower limit is not particularly limited as long as the vegetation of the natural lawn is not inhibited, but 1 or more is preferable. The shape of the void portion may be any shape such as circular or square. A striped shape of continuous rectangles is also preferable. In the case of a striped shape, the maximum interval is 5 crn, and only the base fabric part is fixed at regular intervals (5 crn) in the length direction.
It is preferable to connect them with

The area ratio of the entire void portion to the entire non-void portion is 20 ~
80 inches, especially 30 to 70 inches is preferred. Outside this range, it becomes difficult to fully utilize the advantages of both.

The present invention will be explained below based on the drawings.

FIGS. 1 and 2 are partial perspective views showing an example of the artificial lawn of the present invention, and FIG. 3 is a partial perspective view showing the artificial lawn of the present invention laid on the ground covered with natural grass seeds. FIG. 4 is a partial sectional view showing a state in which a natural lawn is grown and coexists with an artificial lawn.

Form a cloth structure by knitting or weaving two voids of a desired size in the base fabric 1, or punch out the voids in advance, and plant and fix three groups of fibers in the non-void regions. . In addition to this method, void portions 2 having a desired shape and size may be provided by means such as punching in a base fabric in which three groups of fibers are planted and fixed on the entire surface of the base fabric. The mechanical fibers 3 are made of synthetic fibers or other artificial fibers, are knitted, woven, electroplated, or tufted, and fixed by backing coating.

The artificial lawn created as described above is laid on the ground 5 on which natural lawn seeds 4 have been sown in advance, as shown in FIG. 3, and left until the natural lawn grows. Normally, leaves 6 of natural grass grow in about two weeks, and they grow in the voids 2 of the artificial lawn, resulting in a state as shown in Figure 4.

The artificial lawn of the present invention is preferably used in the method of sowing natural lawn seeds according to any of the embodiments described above, but in some cases, it is also possible to lay the artificial lawn of the present invention on top of an already grown natural lawn. be.

The present invention having the above configuration has the following effects.

(1) Since artificial grass and natural grass coexist as vegetation, it provides water permeability, heat protection, cushioning properties, etc., and also exhibits the robustness unique to artificial grass in terms of durability. There is a significant improvement over using it alone. In addition, even in the winter, changes in appearance are covered by the artificial grass green.

(2) Natural grass grows in the voids of the artificial lawn, and its leaves spread out to integrate the two, increasing the effect of laying the artificial lawn on the ground. It is also easy to peel off and remove.

(3) When used on the teeing ground of a golf course, there is little difficulty in sticking a tee into the ground.

(4) When used on baseball, soccer, hockey grounds, golf courses, etc., it has the effect of protecting the base of natural grass from damage caused by spike shoes, golf clubs, etc., and during the breeding season of natural grass. Restoration is also quick.
