Abstract
Elastic elements which can be connected together to form a flooring covering include a rectangular plastic frame, interconnected struts within the frame forming a lattice structure, male couplings in the form of elongated bars extending outwardly of the frame and having end plates, and female couplings in the form of spring latches inside the frame to connect with the elongated bars of adjacent elements. Springs extending outwardly of the frame contact an adjacent element to maintain a predetermined spacing therebetween, while the latches of female couplings contact the stop plates of cooperating male couplings to limit separation of the adjacent elements.
