Framework - assembly, as well as air current limitation for this purpose a direction

摘要

Framework - assembly (4)– with a casement frame (5),– with a window frame (6),– with at least one ventilation channel 15 formed between an outer side (2) and an inner side (3) of the framework - assembly (4),– in the ventilation channel, with at least one air current limitation is arranged a direction (1; 28; 46; 58; 67) with a frame fixed support element (14; 29, 47; 59; 68) pivotable planar limiting element (17; 36, 49; 62; 72), which can be switched over between– an open position, in which the limiting element (17; 36, 49; 62; 72) releases the ventilation duct, and– a closed position, in which the limiting element (17; 36, 49; 62; 72) at least partially closes the ventilation channel 15,– the limiting element (17; 36, 49; 62; 72) is configured such that it is present in the open position, as long as the air flowing through the ventilation duct has a flow velocity, which lies below a limit value,characterized in that the limiting element (17; 36, 49; 62; 72) in the..
