Abstract

751,559. False ceilings. BENJAMINELECTRIC, Ltd. July 9, 1954 [July 9, 1953], No. 20156/54. Class 20(4). [Also in Group XI] In a light-transmitting louvre construction of egg-box form each strip has a beading 8 extending along its entire length and the slot in each strip has a recess-10, the beadings of the strips of one parallel series engaging the recesses 10 of the transverse series of strips. The strips may consist of deformable plastic such as " Vinylite " (Registered Trade Mark) and are stepped at their ends to form shoulders 11 for locating the louvre upon supporting beams 4 of V-section, adjacent lengths of which are supported at their ends by V-shaped channel couplings 5-suspended by rods 3 from e.g. a ceiling.
