Sound-absorbant ceiling sail has visual part made of perforated plate with acoustic layer, locking part made of second perforated plate with acoustic insert and holes for hanging parts which grip flange of visual part using connecting parts

摘要

Ceiling sail has visual part (11) in form of perforated plate (12) made of thin metal sheeting and with acoustic fleece layer and closed upright edge (13) which ends in a flange (14) bent at right angles to the first plate, whose free end corned is turned to the first plate. It has a locking piece in form of a second perforated plate made of thin metal sheeting with acoustic fleece insert, with holes for ceiling hanging parts and with a closed right-angled upright edge (24) whose length- and cross-wise dimensions correspond to those of the edge flange of the visual part. It has at least two connecting profile parts for feeding on and holding the hanging parts. The holding limbs of the connecting profiles cling to the first plate magnetically. The edges of the locking part grip the edge of the flange of the visual part. The through openings and the arresting slits are alternately located in the short limbs of the connecting profiles.
