Abstract
A door lock assembly includes a cam attached to a handle for rotating a rotary drive in response to rotation of the handle. The rotary drive has a driven part rotated by the cam, and a drive part opposite to the driven part. A latch operator is rotated by the drive part so that a latch operating spindle connected to the latch operator can retract a latch. A slide plate is controlled by a key-operated lock unit to prevent or permit rotation of the cam and the latch operating spindle. The door lock assembly is simple in construction and can be assembled easily.
