(57) A door lock assembly has a lock lever (19) for locking a door, and a control lever
(31) connected with the lock lever for swinging the lock lever between a lock position
and an unlock position. The control lever is connected with an lock knob or a key
lock unit of the door. The control lever is swingable between a lock control position
for holding the lock lever in the lock position and an unlock control position for
holding the lock lever in the unlock position. The control lever can swing beyond
the lock control position to a lock over position. The door lock assembly further
has a positioning means (32) which enable the control lever to stop in the lock control
position and the unlock control position. When the control lever is moved to the lock
over position by the lock knob or the key lock unit, a position sensor (29) connected
with the control lever produces a lock signal, which is sent to an actuator. The actuator
is connected with a second door lock assembly for locking a second door. In response
to the lock signal, the actuator puts the second door lock assembly into a lock position
for locking the second door.
