  • Panel, particularly a flooring panel
    Patent number: 6647689
    Abstract: A panel, particularly a floor-covering panel, is provided that has separate horizontal and vertical locking structures. The panel has a first side edge and a second side edge. The first side edge has a groove and a locking lip, and the second side edge has a tongue and a locking tongue. The first side edge of one panel interlocks with the second side edge of another panel without adhesives or fasteners such that the tongue and groove form a joint that provides a vertical interconnection lock and the locking lip and locking tongue form a joint that provides a horizontal interconnection lock. Advantageously, one or more first side edge surfaces opposite surfaces of the second edge locking tongue have a space between them. The separate horizontal and vertical locking structures reduces, if not prevents, damage to the locking structures during joining of panels.
