  • Publication number: 20230349410
    Abstract: A piece of furniture, comprising a first and second furniture part, which are coupled to each other at an angle by means of mechanical coupling means. A female part is made as an oblong slot in the second furniture part with an insertion opening for introducing a male part. When coupling the first furniture part and the second furniture part to each other, the male part is brought from an insertion position in the insertion opening to an end position in the female part by moving the male part and the female part along each other. The male part is situated on a narrow end of the first furniture part and is positioned with its center line between the central plane of the first furniture part and the inner side of the first furniture part. The slot is realized in the inwardly directed flat side of the second furniture part.

  • Publication number: 20220299058
    Abstract: 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.

  • Publication number: 20210207637
    Abstract: 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.
