Abstract
An arrangement of profile members for sash windows, sliding doors and the like which includes interconnected blind frame profile members of similar cross-section along the length thereof connected to one another to form a blind frame. Sash frames are also formed by constant cross-section sash frame profile members interconnected to one another. To accommodate a simple attachment and detachment of a sash frame to a blind frame, a V-shaped elastic mounting profile element is provided which snap-fittingly attaches to the blind frame and guidingly accommodates the sash frame. This elastic profile mounting element is provided along three sides of the frame construction with the other side including a T-shaped aluminum guide rail for accommodating sash rollers or the like. For attaching the glazing to the sash profile members, an acute angled elastic profile element with legs of unequal length is provided, which is stressed so as to elastically clamp the glazing against the sash profile member when in the installed condition. A grip molding profile element is also provided which clampingly engages the sash profile member and also serves to accommodate reinforcing irons and the like.
