Abstract: The invention relates to a floorboard for a flooring system comprising a plurality of mechanically connectable floorboards. The floorboard comprises a first connecting profile along a first side and a second connecting profile along a second side that is parallel to the first side. The first connecting profile is configured for locking engagement with the second connecting profile of another floorboard both horizontally and vertically. The first connecting profile comprises a protruding strip at the bottom face of the floorboard, the protruding strip terminating outwardly in a locking element projecting towards the top face of the floor board. The second connecting profile comprises an overhanging tongue delimiting at its bottom a recess for receiving the protruding strip, the recess comprising a locking groove configured for cooperating with the locking element so as to provide a horizontal locking effect.

Abstract: A synthetic multilayer floor covering has floor panels, each of which comprises at least a first and a second edge with a first and a second connecting profile, respectively. The connecting profiles are complementarily shaped so that adjacent floor panels may be coupled to one another. The first connecting profile of a first floor panel and/or the second connecting profile of a second floor panel is deformed when connecting profiles become coupled with each other. The deformation comprises a component that persists as the connecting profiles remain coupled. The persistent deformation results in stress within the connecting profiles, which are made of viscoelastic material. That material undergoes significant stress relaxation. At standard ambient temperature and pressure, the stress within the first and/or the second connecting profile decreases by at least 40% within 12 hours after the connecting profiles have become coupled.
