Abstract
Abstract The invention relates to an oxygen supply unit equipped with an oxygen generator for supplying one or more oxygen masks. These masks and the generator are accommodated in an openable housing. The oxygen supply unit is improved in that a highest possible savings in weight is achieved while maintaining the stability of the entire arrangement so that oxygen generators can be installed which are useable for a longer duration. For this purpose, the oxygen generator is attached to a strut which is releasably connected to a reinforcing frame of the housing.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
131 words
An oxygen supply unit comprising: an openable housing having a rectangular reinforcing frame having four interconnected side walls; a strut defining a longitudinal axis and having first and second ends; releasable attachment means for releasably attaching said first and second ends of said strut to respective ones of two of said side walls of said reinforcing frame; at least one oxygen mask disposed in said housing; an elongated oxygen generator for supplying oxygen to said oxygen mask when said oxygen supply unit is in use; said oxygen generator defining a longitudinal axis; and, holding means for holding said generator only to said strut so as to cause said axes to extend in the same direction and so as to prevent vibration from being transmitted directly from said generator to said housing.
Claim 2
Dependent Claim
131 words
An oxygen supply unit comprising: an openable housing having a rectangular reinforcing frame having four interconnected side walls; a strut defining a longitudinal axis and having first and second ends; releasable attachment means for releasably attaching said first and second ends of said strut to respective ones of two of said side walls of said reinforcing frame; at least one oxygen mask disposed in said housing; an elongated oxygen generator for supplying oxygen to said oxygen mask when said oxygen supply unit is in use; said oxygen generator defining a longitudinal axis; and, holding means for holding said generator only to said strut so as to cause said axes to extend in the same direction and so as to prevent vibration from being transmitted directly from said generator to said housing.
Claim 3
Dependent Claim
35 words
The oxygen supply unit of claim 1, said reinforcing frame having two side walls parallel to each other and said strut being attachable to said walls so as to extend in a direction perpendicular thereto.
Claim 4
Dependent Claim
43 words
The oxygen supply unit of claim 1, said housing having a lower portion attached to said reinforcing frame for accommodating said oxygen generator and said mask therein; and, said housing further including a cover connected to said lower portion for closing the latter.
Claim 5
Dependent Claim
49 words
The oxygen supply unit of claim 1, wherein a plurality of said masks are disposed in said housing and the oxygen supply unit further comprising a plurality of mask suspending lines connected to corresponding ones of said masks; and, holding means for receiving and holding all of said lines.
Claim 6
Dependent Claim
118 words
An oxygen supply unit comprising: an openable housing having a reinforcing frame; a strut forming a part of said frame and extending along said housing so as to define a space between said strut and said housing; at least one oxygen mask disposed in said housing; an oxygen generator including: a container also extending along said frame and a plurality of interconnected individual candles arranged in said container one behind the other so as to also extend along said frame; and, holding means for holding said generator only to said strut so as to hold said generator in spaced relationship to said housing thereby preventing heat and vibration from being transferred directly from said generator to said housing.
Claim 7
Dependent Claim
118 words
An oxygen supply unit comprising: an openable housing having a reinforcing frame; a strut forming a part of said frame and extending along said housing so as to define a space between said strut and said housing; at least one oxygen mask disposed in said housing; an oxygen generator including: a container also extending along said frame and a plurality of interconnected individual candles arranged in said container one behind the other so as to also extend along said frame; and, holding means for holding said generator only to said strut so as to hold said generator in spaced relationship to said housing thereby preventing heat and vibration from being transferred directly from said generator to said housing.
