SURFACE UNDERLAYMENT SYSTEM WITH INTERLOCKING RESILIENT ASSEMBLIES OF SHOCK TILES

摘要

A surface underlayment system and its method of manufacture that is sandwiched between an impact-receiving upper surface and a lower foundation. The energy absorbing system has subassemblies of interconnected modules that cooperate to absorb and distribute impact forces applied thereto. Each module has one or more frustoconical support structures. At least some of the frustoconical support structures have bases that underlie the upper impact-receiving surface such as a golf putting green, a football field, marine decking, and senior living flooring.

主权项

1. A surface underlayment system that is interposed between a lower foundation and an upper impact-receiving surface, the surface underlayment system comprising:
an assembly of energy absorbing subassemblies, each subassembly having one or more energy absorbing modules that cooperate to absorb at least some impact forces exerted upon the upper impact-receiving surface, the modules also being operable to space apart the upper impact-receiving surface and the lower foundation; at least some of the energy absorbing modules comprising one or more frustoconical support structures, at least some of the frustoconical support structures having a bottom surface and an upper top surface that are connected by a frustoconical sidewall; the upper top surface underlying the upper impact-receiving surface and the bottom surface being juxtaposed with the lower foundation, the upper top surface and bottom surface being operable to coordinate the response of the frustoconical support structures to impact; and at least some of the energy absorbing modules having edge flanges that define at least one elongated female trough and an elongate male lug that are adapted to engage a male lug and a female trough of an adjacent module.
