An opening window for use with curtain wall systems

摘要

An opening window for use with curtain wall systems comprising an outer frame (42) adapted to fit to the framework members of the curtain wall system and an inner frame (48) bearing the glazed portion of the window, the inner frame (48) and the outer frame (42) being hingedly attached to one another and the glazed portion extending so as to be substantially coextensive with the outer frame (42). The appearance of this window does not detract from the sight lines of the building and yet the flexibility of the system is not impaired.
