Abstract
An oxygen box is secured in an oxygen box hole through a panel of an aircraft cabin by fasteners that are positioned in an interior volume of the oxygen box and are inserted through holes in a back wall of the oxygen box that are aligned with fastener openings in an exterior bracket positioned behind the panel and behind the oxygen box opening where the fasteners are received by the fastener openings in the exterior bracket and the fasteners removably attach the oxygen box to the exterior bracket.
Claims20
An oxygen box assembly comprising:
- an oxygen box having an interior volume and a back wall and a front opening on opposite sides of the interior volume, the front opening of the oxygen box providing access to the interior volume of the oxygen box with the interior volume of the oxygen box being between the back wall of the oxygen box and the front opening of the oxygen box, the back wall having holes through the back wall, the oxygen box being configured to be inserted through an oxygen box hole through a panel of an aircraft cabin into a space behind the panel of the aircraft cabin and positioned flush with the panel of the aircraft cabin;
- an exterior bracket that is configured to be attached to a support structure of an aircraft behind the panel of the aircraft cabin, the exterior bracket having fastener openings that are each configured to receive and hold a fastener, the fastener openings of the exterior bracket aligning with the holes through the back wall of the oxygen box with the oxygen box inserted through the oxygen box hole through the panel of the aircraft cabin;
- at least one oxygen mask in the interior volume of the oxygen box;
- and,
- fasteners inserted through the interior volume of the oxygen box, through the holes through the back wall of the oxygen box and into the fastener openings of the exterior bracket, the fasteners securing the back wall of the oxygen box and the exterior bracket together and thereby securing the oxygen box in the oxygen box hole through the panel of the aircraft cabin.

An oxygen box assembly comprising:
- a first support leg having a length with a bottom end and a top end at opposite ends of the length of the first support leg, the bottom end of the first support leg being configured for attachment to a support structure of an aircraft adjacent an oxygen box hole through a panel of a cabin of the aircraft;
- a second support leg having a length with a bottom end and a top end at opposite ends of the length of the second support leg, the bottom end of the second support leg being configured for attachment to a support structure of the aircraft adjacent the oxygen box hole through the panel of the cabin of the aircraft;
- an exterior bracket having a length with a first end and second end at opposite ends of the length of the exterior bracket, the exterior bracket having fastener openings that are configured to receive and hold fasteners, the first end of the exterior bracket is attached to the top end of the first support leg and the second end of the exterior bracket is attached to the top end of the second support leg with the length of the exterior bracket extending over and across the oxygen box hole through the panel of the cabin of the aircraft;
- an oxygen box configured to be inserted through the oxygen box hole in the panel of the aircraft into a space behind the panel of the aircraft and positioned flush with the panel of the aircraft, the oxygen box having an interior volume, the oxygen box having a back wall and a front opening at opposite sides of the interior volume of the oxygen box with the interior volume of the oxygen box being between the back wall of the oxygen box and the front opening of the oxygen box, the back wall having holes through the back wall, the back wall being positioned against the exterior bracket and the holes through the back wall aligning with the fastener openings of the exterior bracket;
- at least one oxygen mask in the interior volume of the oxygen box;
- an interior bracket having holes through the interior bracket, the interior bracket being positioned inside the interior volume of the oxygen box and against the back wall of the oxygen box with the holes through the interior bracket aligned with the holes through the back wall of the oxygen box and aligned with the fastener openings of the exterior bracket;
- and,
- fasteners through the holes through the interior bracket, through the holes through the back wall of the oxygen box and into the fastener openings in the exterior bracket, the fasteners securing the interior bracket, the back wall of the oxygen box and the exterior bracket together and thereby securing the oxygen box in the oxygen box hole through the panel of the aircraft cabin.
