CONSTRUCTION KIT FOR HORIZONTALLY AND VERTICALLY SLIDING WINDOW ASSEMBLIES

摘要

A construction kit for horizontally and vertically sliding window assemblies is provided wherein a single set of extruded profiles are used to construct either type of window. Each window has a main frame including a sill, a header and a pair of jambs which are constructed from a single hollow multi-chambered main frame extrusion. Each window also includes at least two sashes which are likewise framed by a single multi-chambered sash extrusion profile. Other features of the construction kit include snap in glazing profiles which permit the rapid and economical glazing of window panes, snap in members for supporting weather stripping and guiding window sashes to provide extra versatility in the placement of guide rails and weather stripping. A unique system for weather stripping at the meeting rails is also provided whereby a slot for holding weather stripping is provided on the rear surface of the meeting rails so that the weather stripping can be wrapped around the end of the meeting rail and secured by frictional engagement between the rear surface of the rail and the window sash. This not only provides a much faster system for weather stripping the meeting rails but also provides a much more effective barrier against the intrusion of air in the area between the ends of the meeting rails and the window sashes. An additional feature of the construction kit is the two tiered main frame extrusion which provides an extra surface along the outer edges of the window to permit installation of an additional weather stripping, thus yielding a window with superior wind resistance.
