ABSTRACT:
A quick opening window positions a glazed sash in a window opening in weather sealing relation and supports said glazed sash in closed relation to the opening on a sidewardly slidable support which is moved from its normal position beneath the glazed sash to permit the sash to drop into a hollow cavity beneath the window opening. A tension latch arrangement is provided which must be overcome in moving the glazed sash support from its normal position to prevent the accidental opening of the window.
