摘要：<p>A system for locking a door (24) can: (1) lock the door (24) in dead bolt fashion, (2) allow the door (24) to open a limited distance, or (3) allow the door (24) to open freely. The system has a door-mounted latch assembly (20) that includes a base plate (22), an intermediate link (38) pivoted to the base plate (22), and a mode selection and latching assembly (40) that is pivoted to the intermediate link (38). The latch assembly (20) also includes a high strength, "T"-shaped latch member (60), and camming means to slide the latch member (60) back and forth as a control knob (54) is rotated. A latch plate (30) is mounted on the door frame in juxtaposition to the door-mounted latch assembly (20). The latch plate (30) has a cylindrical portion (32) with a vertical slot for receiving the "T"-shaped latch member (60).</p>
