  • Quick-assembly interlocking tile
    Patent number: 5791114
    Abstract: A specially designed beveled edge (26) guides tile interlocks (14) into place and holds them in place during assembly, thereby facilitating ease and speed of interlocking tile (10) assembly for tight fitting interlocks which actually lock contiguous tiles together. Assembly time for an entire surface using such interlocking tiles is greatly reduced in comparison to comparable prior art interlocking tiles with no diminution in interlocking quality or tile wear.
