Abstract
Abstract Universal window structure for use as a single-hung window, a hopper window, or a right or left-hand glider window and having a box frame and at least one movable sash is disclosed. An improved mull cover for securing a plurality of the universal window structures together, sash guide and tilt release structure for permitting tilting of the movable sash out of the plane of the window structure, and sash guide and pivot structure for the movable sash are also disclosed, together with an improved sash balance shoe, improved locking structure for the movable sash, improved glazing structure, improved weather stripping, structure for maintaining the weathertightness of the window structure during high winds, and a combination screen retainer and movable sash seal. The window structure of the invention may be installed from the inside of a window opening by means of unique installation clips and can be installed from the exterior of a window opening in conjunction with a unique installation bracket. Trim extensions are also provided with the window structure for finishing a window opening in which the window structure is installed. The window structure of the invention has provision for weepage installed as a single-hung hopper or as a right or left-hand glider window. The movable sash of the window structure of the invention is separated from the frame thereof and guiding and spacing means to eliminate metal-to-metal engagement between the movable sash and the window frame are provided whereby the window structure is particularly quiet in operation.
