Lavatory oxygen container adaptor
View Patent ↗Various adaptor configurations are provided that allow newly mandated replacement oxygen modules to replace oxygen generators in the same containers that are currently used in aircraft lavatories. The replacement modules and oxygen generators differ in terms of overall interface dimension, geometries and weights. The adaptors enable replacement modules to be mounted without, or with only minimal, modification of the oxygen containers.
1. An aircraft lavatory oxygen container adaptor for mounting an aircraft oxygen module within an aircraft lavatory oxygen container configured to contain an aircraft chemical oxygen generator to be replaced, the aircraft oxygen module having an outer diameter that is smaller than an outer diameter of the aircraft chemical oxygen generator, the aircraft lavatory oxygen container adaptor comprising:
a mounting member connected to the aircraft lavatory oxygen container;
an aircraft oxygen module having a tank portion and a valve portion;
a cylindrical canister enclosing the tank portion of the aircraft oxygen module, the canister having an outer diameter configured to substantially match the outer diameter of the aircraft chemical oxygen generator to be placed, and said canister including an annular cradle and a longitudinal spacer completely within the cylindrical canister for retaining the aircraft oxygen module, the longitudinal spacer defined by a cylindrical body that occupies a first end of the cylindrical canister;
first and second straps connected to said mounting member, said first and second straps extending around said cylindrical canister from a first mounting position on the mounting member to a second mounting position on the mounting member to secure said cylindrical canister and the aircraft oxygen module to said mounting member;
first and second compressible spacer disposed between each of said straps and said canister, respectively, said first and second compressible spacers defining a cavity for receiving the first and second straps therein, respectively; and
first and second cradles mounted to the mounting member at the first and second mounting positions, respectively, the first and second cradles spacing the cylindrical canister from the mounting member;
wherein a portion of the aircraft oxygen module protrudes from an interior of the cylindrical canister.
2. The aircraft lavatory oxygen container adaptor of claim 1 , further comprising first and second fasteners configured to secure said first and second straps, respectively, and configured to positively hold the aircraft oxygen module in said first and second straps.
