A rolling shutter assembly having a shutter support member and a shutter coupled to the shutter support member. The shutter has a plurality of individual slats and a plurality of hinges interconnecting the slats. Each of the slats has a pair of end portions, and the slats include a first set of slats and a second set of slats, each of the slats in the first and second sets being alternated so that each of the hinges is connected to one of the slats in the first set and one of the slats in the second set. The shutter further includes a plurality of extension members extending from the slats and/or the hinges. The shutter assembly has a pair of shutter tracks and an arrangement for rolling the shutter from an extended position in which the end portions of the slats are disposed in the shutter tracks to a retracted position in which the shutter is rolled up on the shutter support member. The shutter tracks further include guide channels and a guide arrangements which cause the extension members to be disposed within the guide channels to cause the slats in the first set of slats to occupy a first relative position and the slats in the second set of slats to occupy a second relative position while the shutter is being unrolled. |
