Description

Pivoting, suspended angular profile panels avoid annoying disruptions, especially in residential areas can lead.

Such springs can be used to simplify Manufacture and assembly advantageously from strip shapes Approaches to existing circuit boards made of elastic plastic, which at the ends de: Winkelproi'ilschienen are attached and the after outwardly directed, bear in the bearing bores in the frame tintiri-iienden bearing journals.

The essential parts of an exemplary embodiment for this ventilation windows according to the invention are shown schematically in a drawing. In it shows

The clear opening of a ventilation window (not shown as a whole) is covered by a number of partially overlapping sections of angle profile rails 1 which extend horizontally between the vertical bars of a frame 3 lining a housing wall opening. The legs 1 α of the angle profile rails 1 close acute angles approaching the 90 angle and form with each other and with the horizontal bars of the frame 3 passage openings in the form of angled slot
