Glazing method
A method of glazing an opening in a wall structure such as an interior wall in an office building, in which a glazing frame is fitted around a glass panel and the panel and frame are inserted into the opening. Clips are installed within the opening and engage the frame so as to prevent displacement of the frame outwardly of the opening. A trim frame is then installed from the opposite side of the opening and is retained by and conceals the clips. The trim frame provides a symmetrical smooth exterior surface.

This invention relates to a method of glazing a framed opening in a wall structure, for example an interior wall in an office building, and to a wall structure including a glazed opening.
BACKGROUND OF THE INVENTIONThe invention has been devised in the context of interior wall systems for buildings, an example of which is shown in U.S. Pat. No. 6,446,396 (Marangoni et al.). This patent discloses a wall system that includes an internal frame made up of vertical posts and horizontal rails extending between the posts. The frame is clad with fascia elements that may take various forms, including glazed panels. For example, in a situation in which, say, one wall of an internal office is required to be transparent, the frame may be clad using a series of glazed panels as the fascia elements.
Typically, the frame carries fascia elements on both of its inner and outer faces, i.e. the face is clad from both sides so that a finished surface is provided both inside and out. In the case of a glazed fascia, this means that there will be two glazed panels separated, essentially, by the thickness of the frame.
In many applications, the use of two glazed panels represents an unnecessary cost and increases installation time. However, simply leaving out one glazed panel may not always represent an acceptable solution in terms of aesthetics and/or structural integrity of the wall system. For example, having only one glazed panel at the outer side of the wall represents a significant unbalanced load on the frame of the wall structure.
An object of the present invention is to provide an improved method of glazing a framed opening in a wall, and a corresponding wall structure which is particularly (though not necessarily) suited to a single glazed application.
SUMMARY OF THE INVENTIONIn one aspect, the invention provides a method of glazing an opening in a wall structure which is defined by frame members of the structure, each having inner and outer lateral faces at opposite sides of the structure and a transverse face that extends between the lateral faces generally normal to the plane of the opening, the method comprising the steps of:
-
- providing a glazing panel sized to fit within the opening;
- installing on said panel a glazing frame;
- inserting the frame and panel into said opening in the wall structure from a first side thereof, the glazing frame surrounding the glazing panel and having a general L-shaped configuration in cross-section defined by a major limb that overlies said flat transverse faces of the wall members and a minor limb that abuts said lateral faces at said first side of the wall structure, said major limb including a channel receiving a marginal portion of the glazing panel;
- installing a plurality of clips for retaining the glazing panel against displacement out of said opening, said clips engaging said glazing frame at a side of the channel opposite to said minor limb and being received in corresponding openings in said wall members; and,
- installing in said opening from a side opposite said first side, a trim frame which is retained in the opening and covers said clips so that they are concealed from view in the assembled wall structure.
The invention also provides a wall structure having at least one opening glazed in accordance with the method of the invention.
As noted previously, the invention is particularly suited to applications in which only a single glazing panel is used. Preferably, the glazing frame is then designed so that the channel that receives the marginal portion of the glazing panel is disposed generally in the median plane of the opening when the glazing frame has been installed. In other words, the glazing panel will be disposed midway between the inner and outer faces of the wall structure. The load represented by the panel then will be supported in a balanced fashion. Preferably, the channel in the glazing frame receives a glazing bead that provides a seal between the glazing panel and the channel in the glazing frame.
Even though the invention has been designed primarily in the context of single glazed openings, it is of course possible that two channels might be provided in the glazing frame for receiving a corresponding pair of glazing panels where a double glazed solution is required. Ideally, the two channels will then be disposed symmetrically about the median plane of the opening in order to properly distribute the load represented by the two panels.
In most applications, the opening in the wall structure will be rectangular, of course requiring that the glazing panel, glazing frame and trim frame will also be rectangular. Typically each of the glazing frame and trim frame will then be formed from four straight frame members mitered at the corners of the panel to form the complete frame. The frame members of each of the glazing frame and trim frame may be aluminum extrusions. It goes without saying that the extrusions will be contoured to provide an aesthetically pleasing appearance at both sides of the glazing panel. The extrusions may of course be appropriately coloured and/or textured according to requirements of the application in which the extrusions are to be used.
BRIEF DESCRIPTION OF THE DRAWINGSIn order that the invention may be more clearly understood, reference will now be made to the accompanying drawings which illustrate a particular preferred embodiment of the invention by way of example, and in which:
For present purposes, it is sufficient to note that the wall structure includes a frame 20 having an opening 22 to be glazed, and that the opening is defined by a pair of horizontally spaced upright posts 24 and a pair of vertically spaced horizontal rails 26 that extend between the posts. The posts 24 and the rails 26 are essentially box section metal fabrications. The lower one of the rails 26 is shown in section in

To install the glazing panel 34 in opening 22, the glazing frame 36 is first assembled to the glazing panel with marginal portions of the panel received in respective channels 62 in the frame members 40 as discussed previously. At this stage, the glazing panel and glazing frame assembly appears as shown in
The upper portion of clip 66 is shaped to define respective hook-shaped portions 74 and 76 at opposite sides of the clip. The extrusion that forms glazing member 40 is shaped to define a corresponding lip 78 over which the hook-shaped formation 74 engages when the clip is installed as shown in
The other formation 76 of clip 66 is shaped to engage with a corresponding rib on a lateral flange 80 of the extrusion that forms the trim frame member 42. Thus, after the glazing frame 36 and panel 34 have been positioned within the opening 22 and the clips 66 have been installed as shown in
It will of course be understood that the preceding description relates to a particular preferred embodiment of the invention only and that many modifications are possible. Of course, the precise shapes of the extrusions shown in the drawings are not critical and may vary. Also, as noted above, it may be required in some applications to provide two similar channels 62 to receive two glazed panels. The glazed panels may be glass or plastic (e.g. laminated), frosted, clear, translucent or finished in any other appropriate style.
