US Patent 10060079 Mat

A movable mat is formed from a plurality of elongate beams arranged in side-by-side relationship. The mat features a recessed area formed from a pair of adjacent notched beams. An elongate connector passes through both of the adjacent notched beams at the recessed area. A portion of the connector within the notch is surrounded by a rigid sleeve. At least one pocket is formed in an upper surface of one of the beams. A rotatable coupler is situated within the pocket. The mat may be moved by attaching lifting equipment to the connector at one of the recesses or to the coupler. To form a flooring system, a plurality of mats may be arranged adjacent each other on a surface of the ground.
