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.
