<p>The device (1) has door operating bars (4a,4b) whose distance relative to one another is variable and which couple doors to move the doors commonly. A linear actuator is coupled to the linear drive via a displacement transducer and drives door operating bar (4a). The displacement transducer pushes door operating bar (4a) such that the second door during unlocking in direction of closure is relieved even the linear drive is already moved in the opening direction.</p> |
