<p>The sliding swivel door has door panels (2, 3) guided top and bottom through rotary arms (4, 5). The door panels are opened and closed by a drive motor whereby the drive takes place through a gear block (13) mounted directly between the motor drive (11) and arm or between the motor drive and the locally fixed rotational point (7, 8) of the arm. In the case of a twin-panelled sliding door two motorised drives driven in synchronisation are each provided with a belt or chain drive.</p> |
