Abstract
Abstract A compact secondary lock means for securement of relatively movable sliding panels or door closures and comprising a lock bolt pressure actuated into locking position with a bolt receiving opening provided on one of the relatively movable members and releasable by pressure against a release member movable along an axis normal to the axis of the lock bolt, the lock bolt being returned to retracted unlocked position by spring biasing means. The release member may be pressure actuated by either hand or foot, the lock means being readily actuated to unlocked position in the event of an emergency. A security lock means which in locked position, restrains relative movement of the members in directions such as in and out, up and down, and parallel to a door panel, and is particularly adaptable to various types of movable doors or closures such as sliding door and window constructions and swinging doors.
