Abstract
A window screen frame includes at least one corner key which has, as an integral component, a stop that prevents the screen frame from penetrating too deeply into tracks in a window jamb. The corner key is preferably molded plastic and includes two legs, each supporting a raised member. The legs meet at an angle to form the corner and the raised members form the stop. In a preferred embodiment, the raised members meet at the corner to form a corner-shaped stop. One or more of the corner keys may also include integral handles, for moving the frame along tracks in the window jamb. The corner keys may further include retreats for receiving locking pins. The locking pins extend through the window frame and into the retreats to retain the window screen frame in a desired position. A window screen frame including at least one of these corner keys also includes frame segments that mate with the corner key. These frame segments do not include stops, and are thus less complex to manufacture than frame segments which include segment-long stops as integral components.
