(54) | Transparent panel for curved walls in revolving doors |
(57) A stationary 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. |
