Abstract
A floor panel for forming a floor covering, wherein this floor panel is at least composed of a substrate; wherein the floor panel, on at least one pair of opposite edges, comprises coupling parts, which coupling parts allow that two of such floor panels can be coupled to each other by means of a downward movement of one floor panel in respect to the other floor panel; wherein these coupling parts, in the coupled condition of two of such floor panels, form a first locking system, which effects a locking in a first direction perpendicular to the plane of the floor panels, and form a second locking system, which effects a locking in a second direction perpendicular to the edges and in the plane of the floor panels.
Claims20
A floor panel for forming a floor covering, wherein this floor panel is at least composed of a substrate;
- wherein the floor panel comprises first coupling parts on at least one pair of opposite edges, wherein the first coupling parts, in a coupled condition of two of such floor panels, form a first locking system which effects a locking in a first direction perpendicular to a plane of the floor panels, as well as form a second locking system which effects a locking in a second direction perpendicular to the edges and in the plane of the floor panels;
- wherein said first coupling parts substantially are formed of the material of said substrate and are realized in one piece therewith;
- wherein the second locking system is formed at least of a downward-directed upper hook-shaped part which is situated on a first edge of said pair of opposite edges, as well as an upward-directed lower hook-shaped part which is situated on a second edge of said pair of opposite edges, which the hook-shaped parts can be engaged behind each other;
- wherein said upper hook-shaped part consists of a lip with a downward-directed locking element, whereas said lower hook-shaped part consists of a lip with an upward-directed locking element;
- wherein said first locking system comprises locking parts in the form of a protrusion, which, in the coupled condition of two of such floor panels, cooperates with an undercut, wherein said protrusion is situated in the proximity of the distal extremity of the upper hook-shaped part and wherein said undercut is situated in the proximity of a proximal extremity of the lower hook-shaped part;
- wherein said upper hook-shaped part is provided with a support surface with which this upper hook-shaped part, in the coupled condition of two of such floor panels, rests on the lip of the lower hook-shaped part;
- wherein said lip of the upper hook-shaped part is provided with an upward-directed recess in which said upward-directed locking element, in the coupled condition of two of such floor panels, is situated at least partially;
- wherein the most upward-situated point of the upward-directed recess is situated higher than said support surface, which in turn is situated higher than the most downward-situated point of said downward-directed locking element;
- and
- wherein the distal extremity of said protrusion is situated farther distal than a vertical closing surface whereat two of such floor panels meet and close in the closed condition, wherein the vertical closing surface is located above and over the protrusion, and between an upper side of the floor panel and the protrusion.
