Abstract:
1. Panels with coupling elements, allowing an interlocking form-fitting connection between the panels comprising first and second panels each provided with coupling elements on one side such that the first panel can be connected form-fittingly to the second panel by a rotary movement around a connecting joint, and wherein the first panel comprises on a further side a projecting flank laterally on the bottom side as an additional coupling element, and the second panel comprises on a further side a projecting flank laterally on the top side as an additional coupling element, and the projecting flank on the top side 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, and further comprising a laterally applied groove on one panel and a laterally attached tongue in another panel, wherein the tongue engages in the groove in the joined state, one flank of the groove is longer than the other flank, the longer flank comprises a recess, the tongue comprises a projecting nose on a bottom or top side, the nose and the recess are arranged such that the nose can latch in the recess, and the side of the tongue comprising the nose comprises a recess, so a gap remains between the side of the tongue comprising the nose and the longer flank of the groove in the joined state of the two panels owing to the recess formed so the open end of the tongue does not touch the projecting flank when the two panels are joined.
