Abstract (en)
[origin: EP1203854A2] The tongue and groove connection is for panels (1,2), particularly floor panels, such as laminate floors, parquet floors, veneer floors, or cork panels and is provided on at least two opposing panel face surfaces (10,20). It incorporates a securing contour (14,24) for counterpoised, positive engagement of two connected panels. On the one side of the connection is provided a double groove with two parallel grooves (21,22) separated by a rib (23). On the other side of the connection is a double tongue with two parallel tongues (11,12) separated by an intermediate space (13). The securing contour is provided singly on the one of the two grooves and the corresponding tongue or doubled on the two grooves and the two tongues.
