Abstract
Floor covering hard panels having at least on two opposite edges, coupling elements made in one piece with the panels, so that several ones of such panels can be mutually coupled, whereby these coupling elements provide for an interlocking in a direction perpendicular to the plane of the panels, as well as in a direction perpendicular to the edges and parallel to the plane of the panels, and whereby these coupling elements are made such that the panels can be rotated into and/or out of one another at least along the above-mentioned edges. The panels are provided, at least on the above-mentioned edges, near the top side, with a part from which has been removed an amount of material such as by a bevel.
