In combination, a sash assembly and a glazing panel, said sash assembly including sash members forming frame means for holding said glazing panel about its periphery, the improvement wherein at least one sash member has a base and spaced side walls extending from said base to define an open channel to the base, said side walls having opposed inner faces, retainers extending into said channel from said side wall inner faces, a rigid support member fitted between said side wall inner faces within said channel and interlocking with said retainers to provide rigidity to said spaced side walls, said glazing panel being positioned between said side walls and supported by said one sash member in a spaced relationship from said rigid support member.
Claim 2
Dependent Claim
123 words
In combination, a sash assembly and a glazing panel, said sash assembly including sash members forming frame means for holding said glazing panel about its periphery, the improvement wherein at least one sash member has a base and spaced side walls extending from said base to define an open channel to the base, said side walls having opposed inner faces, retainers extending into said channel from said side wall inner faces, a rigid support member fitted between said side wall inner faces within said channel and interlocking with said retainers to provide rigidity to said spaced side walls, said glazing panel being positioned between said side walls and supported by said one sash member in a spaced relationship from said rigid support member.
Claim 3
Dependent Claim
56 words
The combination of claim 1 wherein said retainers are opposed and each include spaced opposed lips defining a restricted channel therebetween, said support member having a general I-beam cross-sectional configuration with opposite flanged ends, a said flanged end inserted into a said restricted channel with said opposed lips defining the channel overlying said inserted flanged ends.
Claim 4
Dependent Claim
20 words
The combination of claim 2 wherein said support member end flanges are juxtaposed with said one sash member side walls.
Claim 5
Dependent Claim
102 words
The combination of claim 1 wherein said retainers are spaced generally oppositely located flanges each terminating in a lip directed toward said sash member base, said support member having a general U-shaped cross-sectional configuration including a base and spaced sides extending therefrom and terminating in end edges, said support member base being positioned adjacent said sash member base and each support member side being positioned adjacent a said sash member side wall with said retainer flange lips fitted around said support member side end edges wherein said each sash member side wall is secured to a said support member side for rigidity.
Claim 6
Dependent Claim
54 words
The combination of claim 4 and a threaded fastening means extending through one sash member side wall and the adjacent support member side and being threaded into the other said support member side for drawing said support member sides and said secured sash member sides toward each other when said fastening means is tightened.

Dependent Claim
114 words
The combination of claim 1 and a frame guidably enclosing said sash member, said frame adapted for insertion into an opening in a building structure and including sill, jamb and header parts, at least one of said frame parts including spaced inner and outer sides, said outer side having a longitudinally extending slot therein defined by spaced end edges each terminating in an inturned lip directed towards said inner side wall, a second rigid support member fitted between said inner and outer sides, said second support member extending from said inner side to said outer side and engaging said lip at each outer side end edge to provide rigidity to said one frame part.
Claim 8
Dependent Claim
39 words
The combination of claim 4 and means extending inwardly from said sash member base and each sash member side wall for contacting said support member and spacing it from the sash member base and each sash member side wall.
