Abstract
A door or window assembly includes an opening bounded by a frame including a hinge jamb (12). A panel (18) is hung relative to the hinge jamb via a hinge arrangement (20) so as to swing between an open position and a closed position. An engagement configuration includes a ledge (22) located in fixed relation to the hinge jamb, and a flange (24) rigidly associated with the panel. The engagement configuration allows me panel to swing freely between open and closed positions. In the closed position, the flange (24) is brought into facing relation with the ledge (22) such that force directed to displace the panel (18) within the plane of closure away from the hinge jamb (12) acts to bring the flange into engagement with the ledge.
