Abstract
Flooring panels having a tongue and groove locking mechanism. The tongue-and-groove configuration principle are provided at the areas being connected. The sides of the groove diverge from the groove base and converge at the end away from the groove base. The opening width of the groove is greater than the foremost area of the tongue in the direction of insertion. The tongue exhibits wedge-shaped areas that diverge from front to back which areas exhibit an undercut in the back area of the tongue that conforms to the groove cross-section. The undercut's borders, adjoining the wedge-shaped areas, converge at the same angle as the groove sides toward a connecting bridge that is part of the component.
