Abstract

803,781. Ceiling coverings. BENJAMIN ELECTRIC, Ltd. (Benjamin Electric Manufacturing Co.). Aug. 10, 1955 [Sept. 28, 1954], No. 27966/54. Class 20(4) A ceiling lining comprising a plurality of light-transmissive panels 1 supported in a horizontal position are so constructed that air may pass between the panels 1 and the supports. The panels, which are constructed and supported in generally the same manner as in Specification 749,968, each have parallel corrugations 2 extending therealong in one direction and a channel 3 across each end, supported by V- shaped supports 4 carried by cross-shaped brackets suspended from the ceiling. The channels 3 and outermost channels 2 have an outwardly sloping wall 6 turned over at its top 7. At three positions along the length of each wall 6, the latter is outwardly deformed at 8, the part 8 being turned over at its tip to form a lip 9 which rests on the support 4. Air may pass through the space between wall 6, top 7, and support 4. To prevent the panels from rising off the supports 4, lugs 11 formed on the outer face of each wall 6 engage beneath a flange 10 outwardly deformed from the length of each support 4 which engages a lip 9. In a modification the supports running in one direction are M-shaped and carry acoustic baffles as in Specification 758,889. The lengths of the M-shaped supports which are engaged by the lips 9 have cut-outs to accommodate the lugs 11, the holding of the panels being effected solely by the non-baffle carrying supports. Specification 769,075 also is referred to.
