Publication number: 20250251005Abstract: 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.Type: ApplicationFiled: April 25, 2025Publication date: August 7, 2025Inventors: Luc MAERTENS, Luc DEMAN, Guy VAN HOOYDONCK, Benny SCHACHT

Publication number: 20250251006Abstract: 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.Type: ApplicationFiled: April 25, 2025Publication date: August 7, 2025Inventors: Luc MAERTENS, Luc DEMAN, Mark CAPPELLE, Luc VANHASTEL, Maarten MARRES, Jan VAN TROYS
