Abstract:
1. Panels with coupling elements, allowing an interlocking form-fitting connection between the panels comprising first and second panels each provided with a coupling element on a first side such that the first panel and the second panel can be connected form-fittingly to a third panel by a rotary movement around a connecting joint, and wherein the first panel comprises on a second side, adjacent the first side, a laterally projecting flank on a top portion of the second side as an additional coupling element, and the second panel comprises on a third side, adjacent the first side, a laterally projecting flank on a bottom portion of the third side as an additional coupling element, and the projecting flank on the first panel comprises a first projecting locking element engaging in a corresponding first recess or indentation in the-other flank in the joined state of the panels, which projecting flanks of the panels comprise further coupling elements, locking the panels in an interlocking manner in the vertical direction relative to the surface of the panels, wherein the additional coupling elements are configured such that the first panel can be connected in an interlocking manner by a lowering relative to the second panel without a rotary movement around a connecting joint of said additional coupling elements.
