Abstract (en)
A controllable louvred ventilator having open and closed positions has each louvre (15) pivotally supported at opposite ends between one opposite pair of side members (16) of a frame defining a ventilation opening (14) (Fig. 2) to be controlled by the louvres. The louvres are additionally supported for long spans at at least one location between their ends, on pivot arms (40) carried from an intermediate frame member (42) spanning the ventilation opening (14) between a further opposite pair of the side frame members (17, 18) of the ventilator frame. A control member (46) for the louvres is supported by and is slidable on the intermediate frame member (42), the control member (46) being connected to open and close the louvres by a series of links (56).
