Description

Lawn Liner {Line maker for artificial truf ground}

The present invention relates to a lawn liner, and more particularly to a lawn liner for forming a line in the artificial turf playground.

Recently, as interest in health and leisure activities increases, the public's interest in wearing various sports and enjoying them is increasing. Reflecting these concerns, the government and local governments are increasing the number of parks and playgrounds where they can enjoy various sports.

Currently, parks and sports grounds are built with natural turf, so that various sports can be enjoyed. However, due to climatic conditions, economic feasibility and practicality, there is a limit to laying natural turf.

However, in order to enjoy various sports on the playground where artificial turf is installed, it is necessary to form a line on the artificial turf playground to meet the separate standard prescribed for each sport. By the way, the line is formed for one type of sport, in order to proceed with other types of sports, there is a need to remove the already formed line and then re-form a new line to meet the specifications of another sport.

Conventional methods for forming lines fixed to artificial turf playgrounds include a method of laying artificial turf dyed to form a distinction from floor artificial turf, and a method of painting artificial turf of a part to be formed with a specific color. This has been used.

However, since the method cannot be changed once the line is formed, there is a problem that it is difficult to enjoy other sports that do not conform to the formed line standard in the corresponding Indian grass field.

On the other hand, when painting artificial turf with a specific color, if the line painting is repeated, the line may become hard or there may be a safety accident, and the paint on the artificial turf peels off over time, resulting in the appearance of the artificial turf playground. There is a problem that hurts.

In addition, a technique using a lime powder is disclosed as a general technique applied for the formation of lines of artificial turf, and the lines made of lime powder also become blurred as time passes, especially when the humidity rises or rains. There is a disadvantage that the lime is solidified by the hard to remove the line.

Because of these problems, some use white colored tape to form lines on artificial turf grounds. Korean Unexamined Patent Publication No. 10-2011-0009592 discloses 'line tape for artificial grass'.

The line tape for artificial turf includes a base layer made of a polyethylene resin or a polyvinyl chloride resin film and an adhesive layer formed on one side of the base layer to adhere to artificial turf, wherein the adhesive layer is an acrylic ester co-polymer; Crosslinking agents.

However, the artificial turf line tape is difficult to reuse because it is adhered to the upper surface of the artificial turf of the playground by the adhesive layer, and when the tape is removed, the adhesive component of the adhesive layer is buried in the artificial turf, thereby degrading the quality of the artificial turf.
