<p>A door controller ( 10 ) including an integrated electric motor, said door controller including an integrated stator ( 14 ) provided with at least one coil ( 16 ) placed about the circumference of said stator, said stator fixed to allow only a substantially small degree of rotation of said stator, in use said stator and a rotatable ring gear ( 18 ) adapted to be in electromagnetic interaction with each other so as to rotatably drive said ring gear, rotation of said ring gear effecting movement of said door. A locking mechanism ( 30 ) for use in a door controller ( 10 ), said door controller including a rotatable ring gear ( 18 ) for effecting movement of a door, said ring gear provided with teeth ( 36 ), said locking mechanism including: at least one clutch member ( 32 ) adapted to move in a radial direction, the at least one clutch member provided with teeth ( 34 ) or at least one locking protrusion; at least one resilient member ( 38 ) operatively associated with said at least one clutch member; and, at least one protrusion ( 42 ) operatively associated with said at least one clutch member; whereby, rotational movement of said at least one protrusion effects or allows radial movement of said at least one clutch member which thereby disengages or engages said teeth or at least one locking protrusion of said at least one clutch member from or with said teeth of said ring gear.</p> |
