Abstract

682,148. Ventilator gratings. AKTIEBOLAGET ENKOPINGS VERKSTADER. Aug. 20, 1951, No. 19624/51. Class 137 A grating for regulating the flow of air from conditioning plant comprises a number of bars 2 of equilateral triangular section which are placed parallel to each other between the two opposite sides of a frame 1 the bars being rotatable and laterally displaceable by hand so that the direction of air flow and the passage area between the bars can be adjusted by grouping and spacing. The bars, which are readily removable, are sprung into the frame, elastic strips 3 protected by thin metal strips 4 being provided within the upper and lower sides of the U-section frame.
