<p>A structural framework (25) for an operable wall paenel (10-14). The structural framework (25) includes a top frame member (30), a bottom frame member (31), and opposite side frame members (32, 33). At their respective ends, these frame members (30-33) each include a connecting flange (37, 42) and a pair of flanges (38, 39, 45, 46) flanking the connecting flange (37, 42). At their intersections which define the corners of the framework, the various frame members (30-33) are structured to interfit. At each corner, one of the frame members includes a notch (43) in its connecting flange (42) that is sized to insertably receive the other frame member at that corner. When the frame members (30-33) are so inserted or interfitted together, portions of the flanking flanges (38, 39, 45, 46) of the frame members (30-33) are then connected together to thereby connect together the separate frame members (30-33) of the structural framework (25).</p> |
