Patent ID: 7192065

Claim:
A system for connecting the interior ( 20 ) of a compartment to the exterior of the compartment which comprises: a wall part ( 21 ) of the compartment having a door opening ( 211 ) therein passing through the waIl ( 21 ) from inside to outside; a connector body ( 11 ) sealingly engageable from the outside of the compartment with the wall part ( 21 ) around the door opening ( 211 ); a connection port ( 13 ) passing through the connector body ( 11 ) from an inside facing surface to an outside facing surface of the connector body ( 11 ), the port having an inner opening ( 132 ) on the inside facing side of the connector body ( 11 ) and an outer opening ( 133 ) on the outside facing side of the connector body ( 11 ); a cover ( 12 ) removeably mountable on the connector body ( 11 ) and which when mounted on the connector body ( 11 ) is sealed to the connector body ( 11 ) and together with the connector body ( 11 ) forms an enclosure ( 16 ) that encloses the inner opening ( 132 ) of the port ( 13 ) to thereby isolate the inner opening ( 132 ) of the port ( 13 ) from the environment outside the cover ( 12 ); an outer door ( 22 ) of the door opening ( 211 ) which can seal the door opening ( 211 ) and is openable to allow the connector body ( 11 ) to be engaged with the wall pan ( 21 ) with an inside facing side of the connector body ( 11 ) facing the interior ( 20 ) of the compartment. an inner door ( 23 ) which can seal the door opening ( 211 ) and is openable within the compartment, and is releasably engageable with the cover ( 12 ) when the connector body ( 11 ) is engaged with the wall part ( 21 ), so that the inner door ( 23 ) can be operated to thereby remove the engaged cover ( 12 ) from the connector body ( 11 ) so as to expose the inner opening of the port to the interior ( 20 ) of the compartment. and so that when engaged with the cover ( 12 ) the inner door ( 23 ) seals with the cover ( 12 ) to enclose the parts of the cover ( 12 ) which prior to engagement of the connector body ( 11 ) with (he door opening ( 211 ) have been exposed to die environment outside the compartment and to isolate these from the interior ( 20 ) of the compartment.
