Abstract
An impact absorbing safety matting system for playground structures is set forth herein. The basemat tile utilizes a honeycombed structure beneath the basemat tile's surface layer. The honeycomb structure utilizes a rib network which forms air cavities that in turn compress when impacted to absorb energy. Affixed to the top of the basemat tile surface layer is a texture coat aggregate.
Claims3
An impact absorbing safety mat for placement under playground equipment on an asphalt or concrete subbase, comprising:
- a surface layer having a bottom and outer edges;
- an array of air filled cells affixed to the bottom of the surface layer;
- rib means, extending from the bottom of the surface layer, for defining the array of air filled cells;
- a sloping outer edge means, surrounding all sides of the mat, for preventing the escape of air from the air filled cells;
- sealer and aggregate spread over the surface layer, the sloping outer edge means, and the asphalt or concrete subbase immediate to edges of the mat, said sealer preventing the escape of air therefrom;
- median rib means, extending a shorter distance from the bottom of the surface layer than the defining rib means, for giving added support to the surface layer against a strong blow striking the array of air filled cells;
- and
- outer rib means, extending from the outer edges of the surface layer, for giving added strength to the surface layer, said outer rib means being structurally wider and stronger than the defining rib means.
