ABSTRACT:
This is a window assembly with one sliding window, one fixed window and a rectangular framework made up of extruded framework members with the same cross-sectional profile except for small segments that are removed in the framework members along which the sliding windows slide. Three of these framework members support the fixed window pane along three edges. The sliding window has extruded peripheral members along its edges which have the same cross-sectional profile as one another except where small segments are removed in two of them to slidably interfit with the two framework members along which the sliding window slides. An additional peripheral member of this cross-section is part of the framework and supports the fixed window along its remaining edge. Springs inside the two framework members along which the sliding windows slide urge the sliding window to an open position.
