发明名称 Security window
摘要 A security window guard is permanently installed into pre-existing awning-type windows (also referred to as Miami windows) by first fastening a separate strip inside the window jambs with fasteners that anchor the strip through a jamb to the wall. This strip has an array of holes that incorporate lead-in guides extending from each hole to a free edge of the strip. Subsequently, holes are drilled in the window jambs at locations aligned with a plurality of pins that protrude from the security frame, an array of fixed pins formed on one side of the security frame is inserted into one set of holes, and the security frame is pushed into the window frame. When the security frame is pushed into the window frame the lead-in guides act to compress spring-loaded pins extending from an opposing edge of the security frame. When the security frame is fully inserted in the window frame, the spring loaded pins extend outward into the holes at the ends of the guides, thereby locking the security frame permanently into position.
