Shock absorbing pad for artificial turf or playground {Shock absorbing pad for artificial turf or playground}

The present invention relates to a shock absorbing pad for artificial turf or a playground, and more particularly, rubber chips such as polyethylene foam pads, foamed urethanes, tires, etc., which are disposed under the existing artificial turf and are made of a chemical material to provide a cushioning feeling. Instead, natural coconut mat can be used, so there is little shrinkage expansion due to temperature in summer, lowering the overall temperature of artificial turf to improve the conditions for exercise and fundamentally no odor, radiation or carcinogen. , It has a moisturizing effect through the evaporation of water on the artificial turf properly, and relates to a shock absorbing pad for artificial turf or playground for easy assembly and installation due to the light weight and simple configuration of the product.

In general, many sports such as general school grounds, playgrounds, soccer, baseball, field hockey, tennis, football, etc. are played on artificial turf playgrounds as described in the current introduction. Athletes suffer fewer injuries on natural turf playgrounds when they fall, sliding tackles, etc., but because of their more flexible surface, such playgrounds are often damaged, especially when the sports mentioned above are played. And, strictly speaking, because they are used intensively and by the changing effects of weather conditions.

Artificial turf playgrounds, on the other hand, require less maintenance and can be played more intensively than natural turf playgrounds. In order to approximate the playing characteristics of natural grass playgrounds possible on artificial turf playgrounds, a thick layer of granulated stuffing, such as sand or plastic grains, is used to make synthetic grass fibers in current artificial turf systems. Is provided between them. The thick layer of granules filled in not only provides softer damping and less susceptible movement surface of the forerunner, but also leads to better movement characteristics.

In addition to the generation of radioactive materials such as cesium, the peculiar odor (odor) of polyethylene, etc., of artificial turf is generated, and the foam pad accumulates heat in summer, resulting in high temperature (70-80 degrees) As a result, the foam pad is distorted due to thermal expansion and contraction, or the foam pad is distorted, causing the artificial turf to be unleveled and reluctant to exercise on the playground. Not only this, there was a problem that drainage was not made smoothly due to the use of foam pads, and rainwater was drained during rainy weather, and there was a problem in that water was not recycled.

In addition, the conventional artificial turf has a problem in that it does not perform a cooling role such as natural grass by being drained temporarily through rain or artificial water spraying, and also does not exhibit a moisturizing effect.

On the other hand, the use of chemical chips recycled tires or urethane rubber chips in the lower layer of artificial turf has a problem that not only odors but also toxic chemicals such as carcinogens or heavy metals.

In addition, the existing artificial turf has a disadvantage of being vulnerable to heat such as fire and swelling due to the winter statue because it uses a chemical composition material.

The foregoing invention refers to the background of the art to which the present invention pertains, and does not mean the prior art.
