SURFACE UNDERLAYMENT SYSTEM WITH INTERLOCKING RESILIENT ANTI-SLIP SHOCK TILES

摘要

A recoiling energy absorbing system is interpositioned between an outer shell that is exposed to percussive impact and a foundation. An energy absorbing layer with friction lugs is positioned inside the outer shell. The energy absorbing layer includes one or more energy absorbing modules with optional veins and drain holes. At least some of the modules are provided with one or more energy absorbing units that extend from an upper basal layer. At least some of the energy absorbing units are provided with a flexible wall that extends from the upper basal layer. The energy absorbing units at least partially absorb energy generated by an impacting object due to the flexible wall bending inwardly or outwardly and recoiling nondestructively after single or multiple impacts to its undeflected configuration.

主权项

1. A recoiling energy absorbing system configured to be interposed between on the one hand an outer layer that is exposed to impact, the outer layer being selected from the group consisting of floors, roofs, walls or ceilings in a playing surface, a hockey arena, a roller blading rink, a gymnasium, a basketball court, a tennis court, a wall, a racquetball or squash court, a soccer field, a football or hockey or lacrosse field, a baseball field, synthetic turf, ASTROTURF®, a military blast mat, flooring for industrial, retail or domestic home use, an automotive application, and the like and on the other hand a foundation, the recoiling energy absorbing system having:
interlocking energy absorbing modules, at least some of the modules being provided with:
edges, at least some of the edges having means for interlocking with an edge of an adjacent module, the means for interlocking including energy absorbing units being received by energy absorbing units disposed along an edge of an adjacent module;the one or more energy absorbing units being hexagonally arranged and extending from means for coordinating energy absorbing units having a face that is juxtaposed with the outer layer, at least some of the one or more energy absorbing units having:
a frustoconical flexible wall that extends from the face of the means for coordinating away from the outer layer, the frustoconical wall when viewed from above or below being circular, oblong, elliptical or shaped like a race-track;a floor extending between the flexible walls of adjacent energy absorbing units and configured to be positioned adjacent the foundation;the one or more energy absorbing units at least partially absorbing energy generated by an impacting object by the flexible wall bending inwardly or outwardly and recoiling after impact to or towards an undeflected configuration; anda mechanical friction means for impeding slippage extending downwardly from a floor between at least some energy absorbing units toward the foundation or upwardly from a face of the means for coordinating towards the outer layer.
