Patent ID: 8789334

Claim:
A floor panel, for forming a floor covering, said floor panel being rectangular and having a first pair of opposite sides and a second pair of opposite sides, defining the edges of the panel; wherein said floor panel at the first pair as well as the second pair of opposite sides is provided with coupling parts, wherein said coupling parts are configured so as to enable two of such panels to be coupled to each other; wherein said coupling parts at both pairs of sides provide a locking of two coupled panels in a direction perpendicular to the plane of the panels and comprise integrated mechanical locking elements which prevent the drifting apart of two coupled floor panels in a direction perpendicular to the related edges and parallel to an underside of the coupled floor panels; wherein the panel comprises a core of a material based on synthetic material; wherein at least a decorative layer is provided at the upper side of said core; wherein said coupling parts at both the pairs of opposite sides comprise a lip integrally formed with the core material, said lip having a lower side being in the same plane as a lowermost side of the floor panel; wherein said lip at both the pairs of the edges extends beyond an upper edge of the panels, and comprises one of said locking elements for preventing the drifting apart of the two coupled floor panels; wherein the coupling parts and the locking elements at the first pair of opposite sides are substantially in the form of a tongue and groove; wherein at least at the first pair of opposite sides the coupling parts and the locking elements are configured to enable coupling of two of such panels in a manner free from play; wherein the coupling parts and the locking elements are configured at the first pair of sides to enable joining by an angling motion; and wherein the panel has a thickness of 0.5 to 1.5 cm.
