ABSTRACT:
A side wall panel for a revolving door, consisting of a number of high and narrow strips of flat glass, interconnected by flexible joints and maintained in the desired arcuate configuration by a curved frame. The use of flexible joints permits the panel to be shipped flat. Internal stresses in the joints are minimized by initially manufacturing the panel on a support which is curved to an arcuate shape corresponding to that of the final installation.
