Patent

CA 2678322

A floor panel with coupling devices is provided. The coupling devices have locking elements which include a curved protrusion which is formed on a lower wall of an upper lip of a groove and adjacent to the entrance of the groove, and a curved recess which is formed in an upper side of a tongue and can match with the curved protrusion. Under the cooperation of the elastic deformation of the upper lip of the groove and the engagement of the locking elements, adjacent floor panels can be coupled together by exerting on them a horizontal pressing force and interlocked tightly by meshing engagement of the curved protrusion at the groove and the curved recess in the tongue without glue or other auxiliary binding material so as to ensure that the adjacent floor panels can not move in both horizontal direction and vertical direction. The floor panels are usually used in a floor decoration of indoor environment and have the advantages of easy installation and tight coupling.
