Abstract (en)
[origin: EP0234927A2] A housing (2) defines a ventilation opening (l) controlled by a closing device with two flaps (5, 6) which are alike and are pivotally movable in opposite directions about external hinge axes (l8) (see Fig. 2) by means of pivot drives (7) and which, in their closed position, engage with their edges over a gutter (l9) crossing the ventilation opening (l) centrally as well as over the walls (9, l0; ll, l2) of the housing (2) carrying them, at their upper edge so as to completely cover the ventilation opening (l) in the housing (2) and protect it from the entry of the weather. A transverse girder (8) is secured to the longitudinal walls (9, l0) and engages under the gutter (l9) and supports the pivot drives (7) for the flaps (5, 6). The longitudinal walls (9, l0) of the housing (2) comprise supporting and locking rails (20, 2l) (see also Fig. 3) supporting axially adjustable bearing blocks (24, 25) for the flaps (5, 6).
