Patent No. EP3969683 (titled "A System For Mounting A Suspended Ceiling") was filed by Rockwool on May 14, 2020. The application was issued on Jul 23, 2025.
A suspended ceiling system mounts ceiling tiles (1) to a ceiling structure (2) via detachably engaging hook profiles. At least two first hook profiles (3) are mounted in parallel on the ceiling structure's lower side at a first distance. Each ceiling tile (1) features at least two second hook profiles (4) on its upper side, arranged in parallel at a second distance corresponding to the first. The tiles hang from the first hook profiles. Crucially, the first hook profiles (3) have first receiving openings (31) facing a first mounting direction, while the second hook profiles (4) have second receiving openings (41) facing an opposite second mounting direction when the tiles are suspended.
