ABSTRACT:
A shutter for withstanding hurricane wind forces has an outer rectangular frame formed by four U-shaped channel members. An inner rectangular frame, also formed of four U-shaped blade channels, is mounted within the U-shaped channels of the outer frame. A plurality of Z-shaped blades extend horizontally between the vertical U-shaped inner blade channels and are secured in an angular position by fasteners. The blades each have a pair of horizontal end flanges which are secured at opposite ends to the inner frame, and have an intervening angled panel of reduced thickness to enable the blades to flex and absorb the wind forces. Longitudinal fins are formed on the inner frame channels and engage portions of the outer frame to radiate wind forces exerted on the blades to the outer frame. A pair of spring-biased plunger rods are mounted at the bottom ends of the outer frame for securing the shutter in a locked position. The shutter is assembled by fastening the blades at their ends to two spaced inner blade channels, sliding the inner frame members within the outer frame members, and then securing the outer frame members together by corner braces to trap the inner frame and blades therein.
