JPS597366Y2 - Artificial grass overlay mat - Google Patents

Description

[Detailed description of the invention] This invention relates to an overlay mat used on an artificial grass field.

In recent years, grounds with artificial grass as a ground surface using durable synthetic fiber piles have come into practical use.

However, these durable pile sections are not permanent, and especially at baseball stadiums, during pre-game batting practice, batting takes place in unspecified locations in front of the bench or around the outfield fence. The pile portion of the batting area had the disadvantage of being locally worn out.

If it is a legal site, it would be possible to use a layer of soil such as clay as is currently being done, or to make replacement easier by attaching artificial turf removably as in Utility Model Publication No. 52-610, for example. In the case of simultaneous practice at multiple specific locations, these methods could not actually be adopted.

In order to prevent wear and tear on the pile part, it is possible to install mats such as rubber boards, but in the case of artificial turf, with these general mats, the pile of artificial turf on the ground becomes a fluidized layer, so foot pressure is reduced. Every time I moved, the mat also moved and I was unable to stabilize it.

The aim of this invention is to provide a mat that can be used on an artificial turf field and has the above-mentioned drawbacks improved.

The mat of this invention is an artificial lawn mat in which the upper and lower surfaces of a plate-shaped core material having appropriate hardness are covered with artificial grass having piles that can intertwine with the artificial grass piles laid on the lower surface.

The artificial lawn here is a knitted fabric having grass-like piles made of fibers or composite resin.

An example of implementing this invention will be explained with reference to the drawings.

Figure 1 is a slope view of the artificial lawn mat according to the present invention, Figure 2
3 are cross-sectional explanatory views showing an example of implementation.

1 and 1' are artificial lawns, and it is desirable that the lawns 1 and 1' be fixed and covered on the upper and lower surfaces of the core material 3 with an adhesive 2, but they should be spread over the sides of the core material and fixed with sheet metal or nails. Good too.

As shown in FIG. 2, the artificial lawn 1 used in the present invention is generally made by planting piles 5 on a base fabric 4 using an appropriate method and then drying them with an adhesive 6 to prevent piles from coming off, or by using a third adhesive. As shown in the figure, an artificial lawn 1' may be adopted in which a pile part 5' and a base part 4' are integrally formed by joining or molding resin.

Further, the material of the core material 3 is preferably a hard plywood or resin board, a rubber board, a wood board, etc., but is not limited to these materials.

The presence of the core material 3 has the effect of dispersing the stress of the foot pressure load, does not impair the lawn-like cushioning effect, and minimizes the wear and tear of the ground lawn.This preferred design is a mat with the structure described above. Therefore, it is not only possible to make it into an appropriate shape such as rectangular or circular and easily transport it to any place on the artificial grass ground, but also to use it, it is possible to place the product of the present invention between the piles of the artificial grass on the ground. The individual artificial grass piles on the back of the mat are inserted and the piles intertwine with each other, so the entire mat is firmly fixed.
Even if you do intense exercise on Matsu 1, the mat will not move,
In addition, it is possible to prevent the wear and tear of the pile, and it has the effect of having appropriate grass-like cushioning properties, and it is a mat of extremely practical value that has the same effect even when the pine 1 is used inside out.
