Claim 0:
1. A door for allowing access to an interior space of a housing, one end of the housing is sealed with a cover having a plurality of cover components, said door comprising:
(a) a sun gear comprising a rotational axis, said sun gear configured to be attached to the housing;
(b) a ring having a central axis coaxially disposed with said rotational axis of said sun gear; and
(c) a plurality of planetary gears evenly distributed about said central axis of said ring, each said planetary gear comprising a rotational axis and rotationally coupled to said ring and said sun gear, wherein said rotational axis of each said planetary gear is disposed parallel to said central axis of said ring,
wherein each of the cover components is configured to be attached to one of said plurality of planetary gears and when said ring is rotated with respect to the housing, the plurality of cover components separate to allow access to the interior space of the housing and the cover is configured to be disposed in one of two closed states and an angle of rotation between said two closed states is about 300 degrees.
