Abstract (en)
[origin: EP0133496A2] 1. External frame for a ventilation opening (13), especially with rectangular cross section, which is limited by an upper and a lower frame edge (15, 16) with ledge-type, projecting marginal sections (1), said marginal sections (1) converging, on the one hand, from a vertex projection (3) towards the wall level, and being approximately quadrantally flush, on the other hand, with the frame edge (15, 16), characterized in that the continuous line path (2, 2', 2") limiting the marginal section cross section (1) features a point of discontinuity in the area (4) of the vertex projection (3) in such a manner that the flow of rain water (5) being drained is broken off, without an ensuing interruption of the stream of flowing-in air.
