Abstract

panel (100, 101) comprising a centrally located core (113), at least one first coupling part (107) and at least one second coupling part (108) connected respectively to opposite edges (104) of the core. The first coupling part comprises an upward tongue (114), at least one upward flank (115) lying at a distance from the upward tongue, an upward groove (116) formed in between the upward tongue and the upward flank, at least one first locking element (121) on a distal side (119) of the upward tongue, and at least one fourth locking element (122) on the upward flank. The proximal side (118) of the upward tongue is upwardly inclined towards the upward flank. The upward groove is adapted to receive at least a part of a downward tongue (125) of a second coupling part of an adjacent panel. The second coupling part comprises a downward tongue (125), at least one downward flank (126) lying at a distance from the downward tongue, a downward groove (127) formed in between the downward tongue and the downward flank, at least one second locking element (129) on the downward flank, and at least one third locking element (131) on a distal side (130) of the downward tongue. A proximal side (128) of the downward tongue facing the downward flank is downwardly inclined towards the downward flank. The downward groove is adapted to receive at least a part of an upward tongue of a first coupling part of an adjacent panel. When first and second coupling parts of adjacent panels are coupled together, overlapping contours of the downward tongue and upward groove leads to a pretension between the first coupling part and second coupling part of the adjacent panels. When floor panels with matching tongue and groove couplings are installed loosely onto the subflooring, during the expansion of the floor and its subsequent shrinkage, the floor panels themselves can drift apart, resulting in the formation of undesired gaps. The invention provides a pretensioned tongue and groove coupling with locking elements.
