Structurally-installed access device for accepting connection by a fire hose nozzle to introduce firefighting fluid into an enclosed space of a structure

A nozzle access device configured to be installed in a structural element defining, at least in part, an enclosed space,

• the nozzle access device being configured to accept connection by a fire hose nozzle to introduce firefighting fluid into the enclosed space, the nozzle access device comprising:
• a housing configured to communicate the firefighting fluid from the nozzle to the enclosed space, the housing comprising:
• a first face surrounded by a first flange and having an opening in a portion of the first face, the opening being surrounded by a cylindrical socket extending from the first face in a first direction, the first flange being configured to threadingly engage a first cover configured to selectively seal and unseal the opening,
• a cylindrical body portion extending from the first face in the first direction,
• a second face surrounded by a second flange and having an opening, the second flange being configured to attach to an end of the cylindrical body portion distal from the first face so that the first face, the second face, and the cylindrical body portion define an interior of the housing;
• a movable nozzle connector disposed within the interior of the housing, the nozzle connector having:
• a tapered female connection portion having a seal and positioned to receive and surround an inserted fire hose nozzle in a coupling connection, and
• a cylindrical nozzle stop portion extending from the connection portion, the cylindrical nozzle stop portion being movably coupled within an interior of the cylindrical socket of the first face;
• an attachment rod extending in the first direction from the first cover, the attachment rod being attached, at a first end of the attachment rod, to the first cover;
• and
• a second cover removably engaged with a second end of the attachment rod.
