Abstract:
1. A floor panel, for forming a floor covering, said floor panel being formed of a prefabricated parquet comprising a prefabricated parquet core formed of a material other than medium density fibreboard or high density fibreboard, and a top layer comprising solid wood which is thicker than veneer; said floor panel having an underside; said floor panel formed as a parallelogram all of whose angles are right angles, and having a first pair of opposite sides and a second pair of opposite sides, defining edges of the panel; said floor panel at the first pair of opposite sides being provided with coupling parts substantially in the form of a tongue and a groove, said groove being bordered by an upper lip having a distal end, and by a lower lip, said groove also having an upper and lower wall, wherein the coupling parts are configured so as to enable two of such panels to be coupled to each other and wherein the coupling parts are provided with integrated mechanical locking elements which prevent drifting apart of two coupled floor panels in a direction perpendicular to the related edges and parallel to the undersides of the coupled floor panels; said floor panel at the second pair of opposite sides also being provided with coupling parts substantially formed as a tongue and a groove, said groove being bordered by an upper lip having a distal end, and by a lower lip, said groove also having and lower wall, wherein the coupling parts are configured so as to enable two of such panels to be coupled to each other and wherein the coupling parts are provided with integrated mechanical locking elements which prevent drifting apart of two coupled floor panels in a direction perpendicular to the related edges and parallel to the underside of the coupled floor panels; wherein, at said first pair of sides, said coupling parts and locking elements, inclusive of the tongue, the upper wall and the lower wall of the groove, are made in one piece with said prefabricated parquet core; wherein the coupling parts and locking elements located at said second pair of sides, inclusive of the tongue, the upper wall and the lower wall of the groove are made of a material selected from the group consisting of medium density fibreboard and high density fibreboard.
