发明名称 Multi-layered sports playing field with a water draining, padding layer
摘要 A multi-layered sports playing field including a top layer made of substantially artificial material simulating a natural playing surface such as grass and a padding layer positioned between the top layer and the base or dirt layer. The padding layer is made of a plurality of discrete beads of substantially elastic, resilient material (e.g., foam) with portions of adjacent beads abutting one another and other portions being spaced from each other. Substantially all of the adjacent beads are preferably integrally joined (e.g., glued, fused) together at their abutting portions. The padding layer is very porous and breathable and preferably includes feet members supporting the main body of the padding layer above the base or dirt layer to create a water channel of interconnected portions to enhance water drainage to the sides of the field.
