ABSTRACT:
A safety lock for a window mounted for pivotal movement about a centrally disposed vertical axis embodies a lock assembly housing mounted on the window sill intermediate the vertical axis and a window jamb. An elongated vertically extending locking member mounted on the lock assembly housing is movable selectively to a locked position with its upper end adjacent the housing and to an unlocked position with its upper end spaced from the housing. A latch assembly housing is mounted on the lower portion of the window intermediate the vertical axis and a vertical side frame member. A connector arm is pivotally connected at one end to a lower portion of the latch assembly housing with its other end engaging the locking member to permit pivotal movement of the window selectively to a closed position and to a limited open position. The locking member is moved to its unlocked position by a release element which permits the connector arm to be disengaged from the locking member and permits the window to pivot toward a reversed position.
