PURPOSE: An elastic layer structure for playground and a molding method providing elastic force are provided to intensify simplicity and buffering effect by forming a concavo-convex part on an elastic layer surface for playground. CONSTITUTION: An elastic layer structure for playground comprises a path(47) and a secondary resilient projection(46). The path is formed in the surface of an elastic layer(45). The path is formed in order to drain. The secondary resilient projection is projected along the path. The secondary resilient projection performs a buffering function. |
