Abstract
There is shown a frame in a truck cab which has an elongated lower straight portion, an elongated shorter upper portion that is curved or bowed upwards, and side portions extending between the ends of such lower and upper portions, and sashes movable along the lower portion. Fixed panes are positioned in the end portions of the frame, and the sashes are slidable so their upper ends move apart a significant distance before engaging the upper frame portion, and such distance is sufficient that in their closed positions the sashes have greater headroom in the upper frame section than the depth to which their lower ends extend into the lower frame section. Such sashes are non-removable via U-shaped or box-like guide elements secured to their lower ends, such elements having spring-like walls with flanges which extend laterally below and in interference relation with shoulder ribs in the frame. The flanges have cam surfaces to facilitate insertion of the guide elements in the frame for locking relation therewith during assembly of the window structure.
