Modular Flooring Device and System

Abstract

A modular mat comprises mirror image layers. At least one fitting receiver is integrally formed in a central portion of each layer, and at least one aperture is formed in a flange portion of each layer. The layers are congruently mated and affixed such that the fitting receiver of one layer is disposed through a corresponding aperture of the flange of the opposite layer. The outer surfaces of the layers comprise traction elements, which may be of different grades, such as industrial grade on one layer and pedestrian grade on the opposing layer. A floor covering system is also disclosed comprising a plurality of modular mats disposed in partially overlapping and interlocking relation with adjacent mats.

         22 . A modular mat for forming a floor covering, comprising:
 a central core area;   a flange extending outward from said central core area, said flange disposed along at least one side of said modular mat;   said mat defined by a congruent perimeter;   said central core area comprising attachment edges disposed along at least one side of said mat; and   a plurality of fitting receivers integrally formed in and extending through said attachment edges and said flange, said plurality of fitting receivers configured to receive and restrict a locking pin therein.   
     
     
         23 . The mat as recited in  claim 22 , said flange comprising a sloped incline having a thinner dimension at the outer edge of said flange and a thicker dimension where said flange meets said central core area. 
     
     
         24 . The mat as recited in  claim 22 , wherein said plurality of fitting receivers are formed in said attachment edge such that a receiving end of said fitting receivers is disposed at the surface of said attachment edge and a locking end of said fitting receivers is disposed at the surface of said flange. 
     
     
         25 . A floor covering system comprising:
 a plurality of modular mats, each mat comprising:
 a. a central core area and a flange extending outward from said central core area, said flange disposed along two adjacent sides of said modular mat; 
 b. said mat defined by a congruent perimeter; 
 c. said central core area comprising attachment edges disposed opposite of said flange; and 
 d. a plurality of fitting receivers integrally formed in and extending through said attachment edges and said flange; 
   wherein said plurality of mats are disposed in at least partially overlapping relation such that an attachment edge of one said modular mat overlaps a length of said flange of an adjacent modular mat, and said plurality of fitting receivers integrally formed in said attachment edge overlap corresponding fitting receivers disposed through said underlying flange of said adjacent modular mat.   
     
     
         26 . The system as recited in  claim 25 , further comprising a connection assembly including said fitting receivers and a plurality of pins, wherein each of said pins is disposed in a different fitting receiver through said attachment edge to secure overlapping adjacent mats together. 
     
     
         27 . The system as recited in  claim 26 , wherein each of said plurality of pins comprises at least one protrusion configured for restricting engagement with said fitting receiver. 
     
     
         28 . The system as recited in  claim 26 , wherein said at least one protrusion comprises a ramp configured to matingly engage said fitting receiver so as to produce compressive force when locked. 
     
     
         29 . The system as recited in  claim 26 , wherein said fitting receiver comprises a ramp configured to matingly engage said pin so as to produce compressive force when locked. 
     
     
         30 . The system as recited in  claim 26 , wherein each of said plurality of pins comprises a removable interior blocking wall disposed to prevent material from passing through said pin.
