Abstract
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. The upper wall of the groove in the first tile runs essentially parallel to the plane of the tile, and the tongue on the second tile matches the shape of the groove in the first tile by having a top surface that runs essentially parallel to the plane of the tile and a bottom surface that falls off towards the end of the tongue.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
200 words
A floor tile comprising a top surface; a support material; and an edge profile on at least two opposite edges of the floor tile, the edge profile comprising a modified groove and tongue joint for the purpose of connecting a first tile and a second tile, the modified tongue and groove joint comprising at least one groove and one tongue on each of at least two edges, wherein a tongue on one edge of the first tile and a groove in an associated edge of the second tile rise obliquely upwards from the bottom of the tile, wherein the edge profiles are contrived directly in the support material of the floor tile, in that the tongue on the first tile projects distally beyond said top surface of the first tile in that the surface on a top side of the tongue on the first tile falls away at an angle into a groove in the first tile, in that the tongue on the second tile has an upwardly projecting locking rib on its outer edge, and in that a locking groove which corresponds with the locking rib is provided in a top wall of the groove in the first tile.
Claim 2
Dependent Claim
200 words
A floor tile comprising a top surface; a support material; and an edge profile on at least two opposite edges of the floor tile, the edge profile comprising a modified groove and tongue joint for the purpose of connecting a first tile and a second tile, the modified tongue and groove joint comprising at least one groove and one tongue on each of at least two edges, wherein a tongue on one edge of the first tile and a groove in an associated edge of the second tile rise obliquely upwards from the bottom of the tile, wherein the edge profiles are contrived directly in the support material of the floor tile, in that the tongue on the first tile projects distally beyond said top surface of the first tile in that the surface on a top side of the tongue on the first tile falls away at an angle into a groove in the first tile, in that the tongue on the second tile has an upwardly projecting locking rib on its outer edge, and in that a locking groove which corresponds with the locking rib is provided in a top wall of the groove in the first tile.

The floor tile of claim 1 , wherein the locking groove in the first tile is limited by inclined surfaces.
Claim 5
Dependent Claim
31 words
