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.

A composed element includes at least two panel-shaped elements, which each have an edge zone in which coupling means are present in a profiled part respectively extending in the longitudinal direction of the respective edge zone, and each including an end face extending transversely to the respective edge zone. The profiled parts allow the coupling of the panel-shaped elements together in an interlocking manner. At least one of the panel-shaped elements includes an arrangement which hides from view at least a portion of the profiled part formed at the pertaining edge zone at the location of the end face.

Composed element including at least two panel-shaped elements, which each have an edge zone in which coupling means are present in the form of a profiled part respectively extending in the longitudinal direction of the respective edge zone, as well as each including an end face extending transversely to the respective edge zone, wherein said profiled parts allow coupling the panel-shaped elements together in an interlocking manner, wherein at least one of the panel-shaped elements includes an arrangement which hides from view at least a portion of the profiled part formed at the pertaining edge zone at the location of the end face.

A composed element, such as a piece of furniture, wherein the composed element comprises at least a rear wall, as well as a number of constructional parts forming a whole in which the rear wall has to be provided. The rear wall forms the rear side of the composed element and includes one or more rear wall parts. The composed element comprises seats for installing at least one of the rear wall parts, which are configured such that the rear wall part can be slid into the seats starting from the rear side of the composed element from a position differing from the final plane in which the rear wall part will be situated in the final condition.

Composed element, with at least two wood-based panel-shaped elements; wherein said panel-shaped elements can be coupled to each other at an angle and with a miter joint by means of a locking tongue and groove connection; wherein the tongue consists of a split tongue, with thus at least a first tongue portion and a second tongue portion, as well as a slit situated there between; characterized in that said slit, seen in cross-section, globally extends according to a direction which deviates from the direction of the center line of the panel-shaped element on which the tongue is provided.

A set of panels including a first panel with a first main plane and a second panel with a second main plane. A first edge of the first panel is configured to be locked to a second edge of the second panel, wherein the first main plane is essentially perpendicular to the second main plane, and wherein the first and the second edges are locked in a first direction, which is perpendicular to the first main plane, and a second direction, which is perpendicular to the second main plane. The first edge includes an edge tongue, with a longitudinal direction along the first edge, including a bottom edge, a first surface and an opposite second surface. The edge groove and/or the edge tongue is/are configured such that a greater force is absorbed by the longitudinal central part than by an edge part at third and fourth edges.
