Patent ID: 7770350

Claim:
A floor panel for providing a floor covering, which panel is rectangular, including elongated and square, and comprising a first and a second pair of opposite sides, defining the edges of the panel, an underside and an upper side, wherein at said first pair of opposite sides, the edges are provided with coupling parts substantially in a form of a tongue and a groove, said groove being delimited by an upper lip and a lower lip, such that the coupling parts enable two of such panels to be coupled to each other; the coupling parts are provided with integrated mechanical locking elements which prevent drifting apart of two coupled floor panels in a direction perpendicular to respective panel edges and parallel to the underside of the coupled floor panels; and the coupling parts and locking elements are configured so as to enable two of such panels at the respective edges to be joined by means of a turning movement; wherein at said second pair of opposite sides, the edges are provided with coupling parts substantially in a form of a tongue and a groove, said groove being delimited by an upper lip and a lower lip, such that the coupling parts of the edges of the second pair of opposite sides enable two of such panels to be coupled to each other; wherein the coupling parts at said second pair of opposite sides are provided with integrated mechanical locking elements which prevent drifting apart of two coupled floor panels in a direction perpendicular to the respective panel edges and parallel to the underside of the coupled floor panels; and further wherein the coupling parts and locking elements at said second pair of opposite sides are configured so as to enable them to be engaged and interlocked by a translation movement of one panel relative to the other in a plane including the panels, wherein the coupling parts are configured so as to fit into each other by means of a snap together connection; and wherein at the groove of the second pair of opposite sides, the lower lip is shorter, equal or longer than the upper lip, and wherein, in the case where the lower lip extends beyond the upper lip, the difference in length between the upper lip and the lower lip, measured in the plane of the floor panel, is smaller than one times the thickness of the floor panel.
