Patent number: 12071966Abstract: 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: GrantFiled: July 11, 2023Date of Patent: August 27, 2024Assignee: INTER IKEA SYSTEMS B.V.Inventors: Luc Maertens, Luc Deman, Guy Van Hooydonck, Benny Schacht
