Abstract
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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
145 words
In combination: a frame having spaced straight and curved sections, and end sections connecting the ends of said straight and curved sections, each of said sections being a channel with walls each having inner and outer portions connected by a shoulder transition; a sash having an upper rail extending into said curved section and a lower rail extending into said straight section, and stiles extending between and being connected with said rails; respective weatherstrip means carried by said upper and lower rails and engaging the outer wall portions of said straight and curved sections; and spaced guide and anti-lift elements secured to the bottom of said lower rail, each element having vertical sides with respective flanges extending laterially therefrom, said sides being characterized by spring action, and said flanges being located between said inner walls with said flanges in interference relation with said shoulder transitions.
Claim 2
Dependent Claim
145 words
In combination: a frame having spaced straight and curved sections, and end sections connecting the ends of said straight and curved sections, each of said sections being a channel with walls each having inner and outer portions connected by a shoulder transition; a sash having an upper rail extending into said curved section and a lower rail extending into said straight section, and stiles extending between and being connected with said rails; respective weatherstrip means carried by said upper and lower rails and engaging the outer wall portions of said straight and curved sections; and spaced guide and anti-lift elements secured to the bottom of said lower rail, each element having vertical sides with respective flanges extending laterially therefrom, said sides being characterized by spring action, and said flanges being located between said inner walls with said flanges in interference relation with said shoulder transitions.
Claim 3
Dependent Claim
65 words
The combination of claim 1, wherein said flanges have cam surfaces to engage the outer walls of said straight section and be cammed inwardly thereby to pass between said outer walls upon applying force to said sash during assembly, the sides of said elements springing outwardly to cause said flanges to move to said inner walls and be in interfering relation with said shoulder transitions.
Claim 4
Dependent Claim
22 words
The combination of claim 1, wherein the bottom of said lower rail and the tops of said elements are in nesting relation.
Claim 5
Dependent Claim
25 words
The combination of claim 3, including screw fasteners extending through the tops of said elements, the bottom of said lower rail annd into said stiles.
Claim 6
Dependent Claim
26 words
The combination of claim 2, wherein each of said elements is a U-shaped element with said flanges extending from the lower ends of the sides thereof.
Claim 7
Dependent Claim
33 words
The combination of claim 2, wherein each of said elements is formed as a retangular box open at the bottom and with the flanges extending from the lower portions of opposite side thereof.
Claim 8
Dependent Claim
56 words
The combination of claim 6, wherein portions of each element are slotted to facilitate flexure of said opposite sides to accommodate inward camming of said flanges, the remaining sides of each element being operable to prevent flexure of said opposite sides and withdrawal of said flanges from interlocked position by a lifting force on said sash.
Claim 9
Dependent Claim
63 words
The combination of claim 6, wherein the top of each of said elements has a center boss portion extending parallel to said opposite sides and between the remaining sides thereof, the edges of said center portion being spaced from the top edges of said opposite sides thereof, and said center portion being adapted to be secured to the bottom of said lower rail.
Claim 10
Dependent Claim
18 words
The combination of claim 7, wherein said remaining sides of each element are also characterized by spring action.
Claim 11
Dependent Claim
41 words
The combination of claim 8, wherein the lower edges of said opposite sides of each element extend below the lower edges of said remaining sides thereof, said cam surfaces of said flanges extending to the lower edges of said opposite sides.
