Plastic covering for sports fields, playgrounds and the like

The invention relates to a plastic covering for sports fields, playgrounds and the like, which has the advantage that it requires little maintenance and can be played on even in damp weather.

The invention is characterized by the combination of a substantially smooth sheet of plastic as a base a laid grass cover made of plastic, which is firmly connected to the base.

The lawn cover can have a variety of structures. You can z. B. on the type of room carpets a knotted or woven carpet fabric in which all threads consist essentially of water-insensitive plastic. In such an embodiment, e.g. B. a basic chain and employing a ground weft, wherein all upward fibers would be formed from a second type of warp, the are usually referred to as pile chains and which always initially run in the direction of the basic chain ^, but then with their frayed end are directed upwards. This The embodiment shows that essentially all types of knotting or weaving can be used. With another The lawn cover could be made from a smooth plastic base α exist, the top of which is covered with elastic spines or stalks, made of plastic. The cross-sectional area

this spike or stalk. could increase from top to bottom, so that at the junction with the plastic sheet the Cross-sectional area is the largest, so the greatest strength is also achieved there.

Two exemplary embodiments of the invention are shown in the drawing. i

Fig. 2 shows a lawn made of plastic, in which the · Web is occupied with elastic spines or stalks made of plastic. ■ ·. '

In the embodiment according to FIG. 1, the turf consists essentially of base weft threads J5 and base warp threads -i 4, which form the basis of the turf. In the direction of the basic warp threads 5 are also drawn in, which the pile warps | a room carpet and _t correspond to the protruding end upwards and which correspond to the grass blades. This just now; The woven structure described is attached to a smooth web 1 made of plastic. One can, for example, use polyurethane as the material for the web 1. This material can be spread and distributed in a plastic state. The carpet is rolled up over this still plastic material, the unevenness of which partially sinks into the still plastic base and bonds with it chemically. This creates a very hard-wearing artificial lawn that can be used practically in all seasons.

Όΰζ Detailed ·. A game according to FIG. 2 shows a lawn cover which essentially consists of a web 8 with attached spikes or stalks 9 made of plastic, the cross-sectional area of which increases as it moves. Dieter artificial turf could just as well as with your ». The exemplary embodiment according to FIG. 1 is rolled onto the still plastic polyurethane material of the web 1 and is then connected to this; Combine material chemically so that a uniform and very hard-wearing lawn is created. The lawn cover can be placed directly on the prepared base 2. Smoothly rolled ground or, for example, a layer of macadam or a layer of concrete could serve as a base.
