Abstract
A door or window arrangement has a panel movable relative to an opening bounded by a frame so as to close against a strike jamb or move away from it. A locking element moves between a locked state in which it engages between the panel and the strike jamb to prevent separation of the panel from the strike jamb and a released state in which the panel can be separated from the strike jamb. A linkage is displaced by a terminal part of a closing motion of the panel so that completion of the closing motion can only occur when the locking element assumes its locked state. Preferably, the linkage is deployed so that force applied to displace the panel through the terminal part of the closing motion results in a force applied to the locking element to displace it towards its locked state.
