ABSTRACT:
A hatch cover system including an ellipitcal port opening (12) in a housing (10) and an elliptical cover member (18) supported centrally by a rotational bearing (53) for rotation about a rotational axis (54) normal to the cover member and by pivot pins (57,62) in a gimbal member (24) for pivotal movement about axes (56 and 58) perpendicular to the rotational axis. Arm members (26,28) support the gimbal member (24) pivotally by pivot members (30,31) so that upon rotation and manipulation the cover member (18) can be articulately moved from a closed position on the port opening to an out of the way position with a minimum of volume sweep by the cover member (18).
