Abstract (en)
[origin: EP0911589A2] Air opening device for room ventilation with a louver and/or multifunctional louvers made of plastic material. The air opening device comprises a first air opening ( A ) having baffles ( 15 ) to control the direction of the airflow and , if required , a second air opening ( B ) connectable thereto and provided with slats ( 8 ) which are laterally connected to toothed wheels ( 7 ) made of molded plastic material. The toothed wheels are so reciprocally connected that the deflection applied to a slat ( 8 ) is transmitted to the others ( 8 ) and changes the airflow rate. The casing of the first air opening ( A ) is formed by an "L" shaped element ( 1 ). Magnets ( M ) are applicable to the external part ( 11 ) of the "L" shaped element ( 1 ) , which is forming the frame for the application to the wall, to produce magnetic actraction on the rim ( 91 ) of the metallic conduit ( 9 ) and to allow the removable fixing of the casing. The casings of the air openings ( A-B ) and their baffles and slats ( 15 and 8 ) are formed by extruded pieces of plastic material which can be cut into different lengths thus allowing to obtain air opening devices ( A-B ) having different dimensions. <IMAGE>
