Abstract:
1. A set of essentially identical floor panels each comprising long and short edges together provided with first and second connectors, the connectors are integrated with the floor panels and configured to connect adjacent edges, the first connector comprises a locking strip with an upwardly directed locking element at an edge of one floor panel and a downwardly open locking groove at an adjacent edge of another floor panel for connecting the adjacent edges horizontally in a direction perpendicular to the adjacent edges, the second connector comprises a tongue at an edge of one floor panel, extending horizontally perpendicular to the edge and a horizontally open tongue groove in an adjacent edge of another floor panel for connecting the adjacent edges in vertical direction, the connectors at the long edges are configured to be locked with angling and the connectors at the short edge are configured to be locked with vertical folding, whereby a long edge of a new panel in a second row is configured to be connected to a long edge of a first panel in a first row by angling, whereby a short edge of the new panel and a short edge of a second panel in the second row are configured to be connected with the same angle motion wherein when the new panel is pressed with its upper edge of a long edge against the upper edge of a long edge of the first panel at an angle against the principal plane of at least about 10 degrees, the connectors of the long edges have at least three separate contact points between adjacent parts of the connectors, the contact points being in a single cross-sectional plane of the adjacent long edges, the plane extending from a rear face of the floor panels to a front face of the floor panels.
