Abstract: A parquet board with a groove and tongue edge profile comprising a projecting tongue (14) on at least one edge of each parquet board (10,12) and a receding groove (16) on at least one opposite edge of the parquet board. The top edge of the tongue (14) is provided with a projecting locking lip (24) running in the longitudinal direction of the tongue, and there is a corresponding locking recess (26) running in the longitudinal direction of the groove in the bottom edge of the groove-boundary-forming top groove cheek (28).

Abstract: A floor tile, in particular a laminate panel, parquet element, veneer floor element, ready-to-lay parquet element or such like comprises an edge profile on at least two opposite edges in the form of a modified groove and tongue joint for the purpose of connecting adjacent tiles, with a coincident arrangement consisting of one groove and one tongue on each of at least two edges, of which the tongue on one edge of a first tile and the groove in an associated edge of a second tile rise obliquely upwards from the bottom of the tile. The edge profiles are contrived directly in the support material of the floor tile, the groove in the first tile is disposed directly above its tongue and the lower wall of this groove falls off towards the back end of the groove by the same degree as the tongue on the first tile rises upwards.
