ABSTRACT:
A security screen assembly installable in the jamb of a building window or door for preventing unauthorized access therethrough, while allowing for quick and easy egress, is provided. The security screen assembly includes a screen with a height, a width and side edges, and a frame which is dimensioned to fit within the jamb of a building, and which is attachable to the jamb. The frame defines an opening having a height substantially equal to the height of the screen and having a width which is less than the width of the screen. A channel is formed on a rear surface of the frame surrounding the opening. The channel accommodates the screen such that the channel prevents the screen from being swung inward. At least one double hinge is attached to the frame and to one of the side edges of the screen, such that the screen is slidable in the channel from a secured position, wherein the side edges of the screen are trapped behind the frame, to an unsecured position, wherein the side edge not attached to the hinge is not trapped behind said frame and the screen can be swung out at an angle relative to the frame to an open position. Preferably, the double hinge is a continuous double hinge extending along substantially the entire length of the side edge of the screen.
