Abstract:
1. A method for laying of floor panels without adhesive which, on their opposite longitudinal edges (I, I′) and transverse edges (II, II′), are provided each with profiling which corresponds to one another, in a space for forming a closed floor surface on a laying plane (E v ) in which several panels of the floor panels with their transverse edges (II, II′) are joined and locked to one another into a row and with their longitudinal edges (I, I′) into several rows (R n ), comprising: a) to form a first row (R b) to form a second row (R c) to form a third (R d) in the joining and locking of the transverse edges (II, II′) a locking element of at least the at least one panel which comprises core material of the panels and which is integrally joined to it snaps into contact with a locking edge of an adjacent one of the at least one panel in a same row, and e) during locking by pivoting down or lowering of at least the at least one panel a force acts in a vertical direction (V) on the locking element and is converted at least partially into a force component which acts in a horizontal direction and effects a yielding movement and afterwards a snapping movement of the locking element directed oppositely, wherein the movement of the locking element both in the horizontal direction (H) and in the vertical direction (V) is ensured by releasing of the locking element relative to the core of the at least one panel.
