Abstract
An article suitable for use in surface coverings such as laminate floorings, such articles having an upper planar decorative surface and a lower planar surface, and at least one male edge and at least one female edge. The male and female edges will interlock with corresponding female and male edges on a complimentary article. These male and female edges have profiles that provide the ability to interlock adjacent articles by approaching one article to the other at an angle, inserting the male edge into the female edge and causing the lower planar surfaces of the two articles to become coplanar, thus forming a gapless seam between the articles which can be formed, if desired, without glue and which can be, if desired, watertight.
