Patent ID: 11168482

Abstract:
A panel, including a first edge pair of complementary interlocking retaining profiles on opposing panel edges. One of the retaining profiles has a locking groove having a retaining strip, which protrudes at the free end of the lower groove wall toward the panel surface. The complementary retaining profile has a locking tongue, which, in the joined state, interacts with the retaining surface of the retaining strip, and a play with both vertical and horizontal components so that the retaining profiles are movable perpendicularly to the panel surface and movable perpendicularly to the panel edges and parallel to the panel surface. In a joining step, the bottom side of the locking tongue is laid horizontal onto the retaining strip of the locking groove and then the tongue top side is slid against the inside of the upper groove wall, the tongue top side touching the inside of the upper groove wall in the region of the panel core.
