Abstract
Abstract A commercial floor mat has a plurality of aluminum rails arranged in closely spaced side-by-side relationship and connected together by hinged connectors beneath the rails. Each rail has a pair of downwardly facing grooves on its underside extending along respective edges of the rail. Each connector has a flexible central web and a pair of spaced upstanding tabs disposed in the downwardly facing grooves of adjacent rails. The tabs have flexible barb-shaped ribs extending along their opposed faces to anchor the tabs in the grooves with a friction fit. The flexible central webs of the connectors facilitate hinged movement of connected rails to permit the mat to be rolled onto itself into a compact configuration.
