Abstract
A door lock system has a closing mechanism for bringing an ajar condition of a door into a fully closed condition. The fully closed condition of the door is locked for the sake of safety by the locking operation of a locking-and-unlocking mechanism. The locked condition of the door is released by an unlocking operation of the locking-and-unlocking mechanism. Moreover, by actuating a double lock mechanism, the door under the locked condition is further brought into a double-looked condition under which the unlocking operation of the locking-and-unlocking mechanism cannot be established. The closing mechanism, the locking and-unlocking mechanism, and the double lock mechanism are driven by a common electric motor thus allowing the door lock mechanism to be reduced in size and manufactured less expensively.
