An improved apparatus and method of sliding window construction are disclosed. When moving in an open position, a sash member is guided for movement in a first plane generally parallel to the window frame opening. When moving toward closure, the sash is guided by rotatable glide members that simultaneously transversely move all four corners of the sash into closure under cam action of the glides, to uniformly compress a weatherstrip seal around the entire perimeter of the sash. The transverse movement between open and closed positions can be performed in a manner such that the general plane of the sash remains parallel to the first plane throughout the transverse movement phase. Means are provided for retainably maintaining the sash at discrete positions along the transverse path of the sash during closure.

A window construction of the type having at least one movable window sash, comprising: (a) a frame having a sill; (b) at least one sash mounted for sliding movement in said frame; (c) a first guide track on said frame for slidably supporting said sash and for directing movement of the bottom of said sash along said frame, said first guide track projecting above said sill and longitudinally extending therealong; (d) a second guide track on said frame in generally opposed relation to said first guide track for directing longitudinal movement of the top of said sash along said frame; and (e) glide means pivotally mounted to said sash and cooperatively mounting said sash between said first and said second guide tracks for supportively moving said sash along and between said opposed tracks; said glide means being operable in a first position within a first movement zone of said frame to guide said sash for movement along said first and second guide tracks in a first plane, and being automatically rotatable toward a second position within a second movement zone of said frame when said sash approaches a closure position to transversely move the entire sash to a second plane parallel to said first plane in a manner such that the general plane of said sash remains substantially parallel to said first plane during said transverse motion.
