In the construction of window and door assemblies, it is common to use insulated glass panel units of the general type disclosed in U.S. Pat. Nos. 5,003,747 and 6,675,537 which issued to or are owned by the assignee of the present invention. Usually, the insulated glass units include two parallel spaced rectangular glass panels having peripheral edge portions which receive a rectangular spacer frame. The edge portions and spacer frame are bonded and sealed together by a bonding compound such as a butyl rubber compound or a similar bonding material surrounding the spacer frame. The insulated glass panel unit is assembled into a surrounding rectangular sash frame and is retained by glazing members or beads. Preferably the sash frame and glazing beads are formed from extrusions of plastics material such as polyvinyl chloride (PVC). Such insulated glass panel units are commonly used in fixed window assemblies such as picture windows, single hung windows, sliding windows, bow and bay windows and sliding and swinging patio door assemblies such as disclosed, for example, in U.S. Pat. No. 6,318,036 which issued to the assignee of the present invention.
In insulated glass panel units as described above, it is common for the outer edges of the glass panels to be exposed and unprotected during handling and shipping or be covered by a thin layer of the bonding and sealing compound. When the outer edges of the glass panels are relatively unprotected, insulated glass panel units must be carefully handled and carefully protected during shipping. Also, when the edge surfaces of the glass panels are exposed, the personnel handling the insulated glass panel units need to wear gloves in order to avoid cutting their fingers or receiving glass splinters. It is also desirable for a fixed window assembly, such as a picture window assembly, to provide for conveniently removing the insulated glass panel unit in the event of glass breakage or damage or moisture seeps into the space between the glass panels and results in etching the inner surfaces of the glass panels.
The present invention is directed to an improved window assembly having insulated glass panels and which is ideally suited for use in a fixed glass window unit such as a picture window, a single hung window and sliding and swinging patio doors assemblies. The window assembly of the invention provides for conveniently handling and shipping an insulated glass panel unit while protecting the unit and also provides for conveniently removing the insulated glass panel unit from the surrounding sash frame and from the inside of the window assembly in the event the unit requires repair or replacement. In addition, when the insulated glass panel unit is inserted into the surrounding sash frame, the unit locks to the sash frame so that it is precisely located and is prevented from shifting laterally relative to the sash frame without the use of spacers.
FIG. 1 is an elevational view of a fixed window assembly constructed in accordance with the invention;
FIG. 2 is an enlarged vertical section taken generally on the line 2-2 of FIG. 1 and with a center portion broken away;
FIG. 3 is an enlarge horizontal section taken generally on the line 3-3 of FIG. 1 and with a center portion broken away; and
FIG. 1 illustrates a window assembly 10 which includes a rectangular outer sash frame 12 formed by elongated sash frame sections or members 14 and 16 which are extruded of a rigid plastics material such as rigid polyvinyl chloride (PVC). The sash frame members 14 and 16 are rigidly connected at the corners of the frame 12 by mitered cuts and welded corner joints 18. As used herein, the term rectangular with respect to the shape of the frame 12 also includes a square frame. Also, instead of the mitered cuts and welded corner joints 18, the frame sections or members 14 and 16 may be rigidly connected by mechanical fasteners such as screws.
Referring to FIGS. 2 and 3, each of the frame sections or members 14 and 16 are shown with the same cross-sectional configuration, and the outer tubular portion of each sash frame member is shown as substantially rectangular in cross-section. However, it is to be understood that the outer portion of each sash frame section or member may have any desired cross-sectional configuration. As also shown in FIGS. 2 and 3, each of the sash frame members 14 and 16 includes a laterally inwardly projecting flange portion 22 having an inwardly projecting longitudinally extending rib 24 and an inwardly projecting flexible lip seal 26. As generally known in the industry, the flexible lip seals 26 are co-extruded of a PVC material having a lower durometer so that the lip seals are somewhat flexible when compared with the substantially rigid PVC material forming the sash members 14 and 16. Each of the sash frame members 14 and 16 also has an inner wall 28 with an offset or step portion 29 forming a longitudinally extending shoulder 31.
An insulated glass panel unit 35 includes a rectangular inner glass panel 36 and a parallel spaced rectangular outer glass panel 38. In a conventional manner, the glass panels 36 and 38 are spaced parallel by an internal rectangular spacer frame 42 which is commonly formed from a roll formed aluminum sheet metal strip, but may also be formed from another form of spacer material. A bonding compound or material 44, such as a compound of butyl rubber, surrounds the spacerframe 42 and bonds to the peripheral inner surfaces of the glass panels 36 and 38 to form a sealed air-tight space 46 between the glass panels. The space 46 may be filled with a suitable gas such as argon, and the spacer frame 42 may be used to enclose a desiccant material to absorb any moisture within the space 46.
