There is provided a door mechanism comprising a door (20) and a door closure mechanism (22) for moving the door (20) between a first, open, position and second, closed position. The door closure mechanism (22) comprises a drive motor (32) coupled to a drive screw (34), the drive screw (34) having a first, right handed thread portion (56) and a second, left handed thread portion (58), a first drive nut (60) threadedly engaged with the first thread portion (56), a second drive nut (62) threadedly engaged with the second thread portion (58), a first drive linkage (70) pivotally coupled to the first drive nut (60) at one end (72) and to the door (20) at a second, opposed end (80), and a second drive linkage (76) pivotally coupled to the second drive nut (62) at one end (78) and to the door at a second, opposed end (80). Rotation of the drive motor (32) causes the first and second drive nuts (60, 62) in opposite directions along the drive screw (34) so as to raise or lower the door (20) relative to the drive screw (34).
