    摘要: Composed element, wherein this composed element comprises at least two panel-shaped elements, which substantially are formed from a board material; wherein said panel-shaped elements are interconnected at an angle by means of coupling devices including a tongue and a groove, which coupling devices substantially are made as profiled parts in the board material; and wherein said coupling devices also include locking elements, which, in coupled condition, prevent the moving apart of the tongue and groove. The panel-shaped elements are formed on the basis of board material in the form of particle board consisting of two or more layers, which in respect to the average fineness of the particles, show a different degree of fineness, namely a basic layer with coarser particles, more particularly chips, and at least one outer layer, or at least a more outward-situated layer, which is of a finer composition than the composition of the basic layer, in other words, with particles, chips, respectively, which on average are finer.

    摘要: A composed element includes at least two panel-shaped elements, such as a locking tongue and groove connection, that are arranged to be coupled to each other at an angle, either directly or indirectly by means of an intermediate piece. The connection includes, at least at one of the panel-shaped elements, a tongue or groove, cooperable with a groove or tongue provided on the other panel-shaped element or on the intermediate piece. The tongue includes a split tongue, with at least a first part and a second part, and a slit located therebetween. A locking part is located at the outer side of at least said first part wherein the slit, seen in cross-section of the tongue, defines at least one side, the course of which, seen in cross-section, deviates from the main direction belonging to the tongue.
