摘要

In the wing and blind frame profile for a window, pref. of plastic, the wing profile comprises a multi-part centre box piece, possibly metal reinforced, with protrusions on the glazing face to hold external sealing and internal glazing batten. The side facing the blind frame has two extensions with sealing units for fitting against extensions on the similarly shaped blind frame profile, which also has inside and outside pairs of extensions on the wall side. The centre box piece (6a-6c) for the wing (1) incorporates a piece (6c) on the outside with an angular S-shaped hook profile unit (15). The bottom end (15a) of this is for fitting against a sealing unit (3) held in a groove (3a) in a forward chamber (18) on the blind frame profile (2).
