Abstract: The “S” storm shutter system is a new type of protection from wind storms and other weather phenomenon. It uses a series of low-profile “S”-shaped interlocking panels. These panels are secured by straps on either side which are then tightened by fixing them to the wall. This creates a protective system whose profile is significantly less than any other system on the market today. Because of this low profile, the wind resistance is drastically reduced. In addition, once the initial anchors are installed, this system requires no tools to assemble or disassemble. This is an important factor when considering the time constraints in preparing for an oncoming storm.

In the case of an opening type skylight, by securing the protective device to the curb, no interference is contributed to the skylight to hinder the opening mechanism of the skylight.

Abstract: A security screen with a main frame having radial sections which interconnect with radial sections of a subframe when the screen is closed to strengthen the screen and increase its resistance to displacement due to sustained or impact loads. Brackets attached to the radial sections of the main frame have pins aligned to fit into holes in the radial sections of the subframe when the screen is closed. The brackets and pins serve to prevent the radial section of the main frame from bending inward under a force applied to the screen cloth by effectively combining the strength and rigidity of the main frame and subframe. Thus, the force required to displace the screen cloth a given distance is increased. The increase in strength and rigidity is accomplished without increasing the dimensions of the screen or its supporting structure. Also, the brackets serve to inhibit the security screen from being pried open. Other means to interconnect sections of the main frame and subframe are disclosed.

Abstract: Disclosed is a shutter system and its panels in which at least one panel is formed of corrugations, and in which the subject panel is perforated. Ideally, the perforation is employed in a panel having an isosceles trapezoidal rib, with the perforations running the full length of the face of the rib.
