24 Claims

1. A structure comprising of at least first, second and third identical boards having planar surfaces and laterally mounted locking elements along a first common joint, said locking elements being wedge-shaped and having a width relative to the first common joint that decrease entirely along the length of the boards in a linear manner or increase entirely along the length of the boards in a linear manner, wherein the locking elements are made in such a way that, simultaneously, by displacing the first board relative to the second board along the first common joint, the first board can be connected with the second board in a positive fit along the first common connecting joint, both in a perpendicular direction relative to the planar surface of the board, as well as in a parallel direction relative to the planar surface of the board, and, at the same time, in a perpendicular direction relative to the first common joint, and the first board can be connected with the third board in a positive fit along a second common connecting joint, at least in a perpendicular direction relative to the surface of the board.
