[0001] The invention relates to a container for a supply unit, in particular an oxygen supply
unit and/or a passenger supply unit (PSU), having a container well at least, wherein
a container door can be pivotably joint at a container well's edge, in particular
pivotable about a hinge at the container well's edge. Further the invention relates
to an oxygen supply device having an oxygen supply unit stored in the container. Further
the invention relates to a passenger supply unit (PSU) having a passenger appliance
stored in the container. Further the invention relates to a system of an arrangement
of a number of containers, each for a supply unit, in a ceiling-panel along an aircrafts
cabin, in particular along an aircrafts cabin alley of seats, wherein each supply
unit is stored in a container.
[0002] A passenger service unit as known in the state of the art are widely used in civil
aircraft comprising for instance a reading light, a passenger or crew air or oxygen
supply device, oxygen masks, warning lights and the like passenger appliances. In
particular an oxygen supply unit usually is part of an oxygen supply device wherein
the unit is stored in a container of the aforementioned kind. In some aircrafts one
passenger service unit is provided for each seat of a passenger and crew member. In
other aircrafts one single passenger service unit is provided for a number of the
seats, for instance in a particular for a row of seats. A row usually is aligned crosswise
to an alley of seats.
[0003] Containers of oxygen supply units of the aforementioned kind usually are arranged
adjacent to each other, side by side, to allow an arrangement of a number of oxygen
supply devices in a ceiling-panel along an aircrafts cabin, in particular along an
aircrafts cabin alley of seats. Such oxygen supply devices are adapted to temporarily
or continuously provide oxygen to a passenger or crew member of an aircraft. Various
methods of generating oxygen are known; basically one is adapted for physically generating
oxygen gas by means of an oxygen pressure cylinder and another one is adapted for
chemically generating oxygen by means of a chemical oxygen generator or another one
could be an OBOGS (on-board-oxygen-generating-system) or centralized Gaseous Oxygen
Systems. Thereby a certain amount of air or continuous air flow comprising a sufficient
or high concentration of oxygen can be provided to a passenger or crew member like
for instance described in laid-open European patent application
EP 2 168 635 A1 of the applicant.
[0004] A general desire associated with modern aircrafts is to provide an in general lightweight
appliance which also holds in particular for the aforementioned container for an oxygen
supply unit. Also efficient manufacturing and maintenance of the aircraft and in particular
the safety relevant systems are desirable; however nevertheless a safety standard
according to numeral regulations shall be met. In particular this holds for an aforementioned
container for an oxygen supply unit which e.g. has to withstand safely relative high
surface temperatures when using a chemical oxygen generator for generating oxygen
in the container. Further the container for an oxygen supply unit shall be resistant
against an accumulation of electrical load on the container; this is to avoid in any
case not allowable electrical discharges or the like which would endanger electrical
safety systems in the aircraft. Thus the container must not be inflammable or meltable
even upon extensive heat or flame exposure.
[0005] Nevertheless even in case of a chemical, electrical or heat impact or the like hazardous
impact to the container a mechanical strength of the container shall be such that
the container is able withstand stress and pressure be that it may from the surroundings
of the container or from an aircrafts cabin construction. In
EP 0 545 118 B1 a container of the introduction is described, wherein mechanical stability is achieved
by numerous depressions from a container wall or the like. It is desirable to provide
an improved adjustment of the mechanical stability of a container for an oxygen supply
unit also considering the aforementioned demands and safety requirements of the container.
[0006] Accordingly, it is a major object of the present invention to provide a container
for an oxygen supply unit which as such is improved in mechanical strength. Further
it is an object of the invention to provide a mechanically strengthened container
for an oxygen supply unit wherein nevertheless the container is resistant to hazardous
impacts. Still further it is an object of the invention to provide a mechanically
strengthened container for an oxygen supply unit resistant to hazardous impacts and
which is nevertheless easy to manufacture; also easy maintenance or assembling in
an aircrafts cabin is preferred. It is still further another object of the invention
to provide a container which has sufficient mechanical strength when arranged adjacent
to one or two further containers in a row of a number of containers for oxygen supply
devices in a ceiling-panel along an aircrafts cabin.
[0007] As relates the container the object is achieved by a container of claim 1. In accordance
with the invention the container has a container well wherein the container well at
least consists of a sheet moulded compound material moulded from a composite of thermoset
sheet material based on fiber-reinforced polymer matrices mainly.
[0008] The invention also leads to an oxygen supply device having an oxygen supply unit
stored in a container according to the invention. The oxygen supply unit can be based
on oxygen pressure effect and thus has an oxygen pressure cylinder. Additionally or
alternatively the oxygen supply unit can be based on chemical oxygen generation and
thus has a chemical oxygen generator. In particular the combination comprises a chemical
oxygen container combined with an oxygen pressure buffer and a downstream connected
electronic or mechanical float regulator.
[0009] The invention also leads to a passenger supply unit (PSU) having one or more passenger
appliances stored in a container according to the invention. Thus the inventive concept
recognized, that in a first variant a passenger appliance and an oxygen supply unit
can each be stored in a segregated configuration in a container according to the invention.
[0010] In a particular preferred development the invention also leads to a passenger supply
device having a passenger appliance and an oxygen supply unit stored in a container
according to the invention. In this second variant the inventive concept recognized,
that a passenger appliance and an oxygen supply unit can be stored in an integrated
configuration in one single container according to the invention.
[0011] The invention also leads to a system of an arrangement of a number of containers
according to the inventive concept. In a preferred development the containers are
arranged for respective support of each other at at least one of each of the containers
well's edge.
[0012] In particular the system has an arrangement of a number of oxygen supply devices
and/or a number of passenger supply units in a ceiling-panel along an aircrafts cabin
wherein each device and/or unit is stored in a container according to the invention.
Particular prefered the containers are arranged for respective support at the containers
well's edge. In a particular preferred development an arrangement of containers for
oxygen supply units can be adjacent to or combined with a panel or another arrangement
of containers for passenger supply units.
[0013] In particular in an alternative the system has an arrangement of a number of passenger
supply devices, wherein each supply device has a passenger appliance and an oxygen
supply unit stored in a container according to the invention. In particular an arrangement
is in a ceiling-panel along an aircrafts cabin, in particular along an aircrafts cabin
alley of seats. The invention recognized that a sensitive weightening of the advantages
and disadvantages for a container of an oxygen supply unit with regard to mechanical
strength as well as further safety demands and resistance to heat, flammability, electricity
discharge and other hazardous impacts begins with a careful selection of the material
of the container. The invention on the one hand recognized that for instance aluminum
or other metal based materials for providing the container has advantages with regard
to mechanical strength and resistance to mechanical stress. However, in each case
a metal material container, in particular also an aluminum container, can be electrically
uploaded and therefore endanger an electrical discharge during hazardous situations
in an aircrafts cabin. Thus an aluminum container for an oxygen supply unit has to
be grounded to an aircrafts construction for instance by bonding or the like contact
methods. This leads to rather high maintenance and assembly costs in addition to the
manufacturing costs for an aluminum container for an oxygen supply unit. On the other
hand the invention recognized that plastic materials have severe disadvantages with
regard to stability and mechanical stress. Also, as compared to an aluminum container,
a plastic container can be of increased weight. In particular this holds true when
a plastic container is to be supplemented to achieve a desired mechanical strength
and resistance to hazardous impacts for instance by means of an increased wall thickness
of the plastic container. These limiting conditions in mind the invention recognized
that surprisingly the container well at least, in particular the container well and/or
the container door, advantageously consists of a sheet-moulded compound material according
to the invention were moulded from a composite of thermoset sheet material based on
fiber-reinforced polymer matrices mainly.
[0014] By providing a sheet-moulded compound material for the container well at least, in
particular the container well and/or the container door, the invention provides a
good compromise between an advantageous solution for resisting mechanical strength
on the one hand and an advantageous solution for resisting electrical uploads and/or
inflammability or other hazardous impacts on the other hand. The invention recognized
that sheet-moulded compound materials --like for instance based on polymer matrices
selected from the group of polymer matrices selected from one or more of Bis-Maleimids
(BMI), Epoxy (Epoxide), Phenolic (PF), Polyester (UP), Polyimide, Polyurethane (PUR)
or Silicone or the like-- can be manufactured sufficiently lightweight by implementation
of fibers and also can be reinforced due to the fibers. In a particular preferred
development it has been recognized that an unsaturated polyester resin or an epoxy
or phenolic resin system is particularly advantageous to meet the compromise between
a good mechanical stress resistance and a resistance to inflammability and electrical
discharge or other hazardous impacts.
[0015] In particular with regard to the system of an arrangement of a number of oxygen supply
devices in a ceiling-panel along an aircrafts cabin the invention recognized that
the inventive use of a sheet-moulded compound material for the container well and/or
the container door has sufficient flexibility and forms a good basis to provide support
regions of adjacent containers at the containers well's edge. The invention recognized
thatwhereas aluminum containers fulfill in particular side stability when arranged
between adjacent containers for providing an arrangement of a number of oxygen supply
devices nevertheless the same-- arrangements with plastic containers is far away from
providing sufficient side stability. In particular the invention recognized that even
when a plastic container might be considered to be as such stable; nevertheless in
an arrangement of adjacent containers for providing an arrangement of a number of
containers for oxygen supply devices a plastic container is endangered to collapse
or being bent or deform when exposed to mechanical stress or pressure loads, in particular
during an aforementioned hazardous impact in an aircraft's cabin.
[0016] Surprisingly, by using sheet-moulded compound material, the inventive concept allows
for a container well's edge of sufficient support and stability between adjacent containers
for supply units, in particular for oxygen supply units and/or panels of passenger
supply units. Thus, in particular within a row arrangement of containers side by side
for supply units (be that it may be for oxygen supply units or passenger supply units
in a panel or another arrangement) along an aircrafts cabin alley of seats, when one
container supports an adjacent container by contact the sheet-moulded compound material
shows up to have particular advantageous features superior of those of aluminum and
plastic materials as such.
[0017] For each of the aforementioned features it is claimed independent protection independent
from all features of this disclosure.
[0018] These and further developed configurations of the invention are further outlined
in the dependent claims. Thereby the mentioned advantages of the proposed concept
are even more improved. For each of the features of the dependent claims it is claimed
independent protection independent from all features of this disclosure.
[0019] It turned out in a preferred development that the container well and/or the container
wall can be moulded from the composite of thermoset sheet material based on fiber-reinforced
polymer matrices mainly; for instance by deep-drawing moulding preferably. Nevertheless
also compression moulding and/or injection moulding is possibly used for providing
the container well and/or the container door from the composite material. In particular
the moulding is assisted by a suitable thermoforming process of raised temperature
according to the needs of the polymer matrice used.
[0020] Generally a sheet-moulded compound material can be provided by dispersing rather
long length fibers (greater than one inch); e.g. of chopped glass fibers on a bath
of polymer matrices of thermoset material like polyester resin or the like. Generally
SMC is described in the standard as EN14598. The longer the fiber is in the sheet-moulded
compound the better the result for the instant inventive concept turns out.
[0021] In a particular preferred embodiment the sheet-moulded compound comprises directed
long fiber systems also known as C-SMC material for providing endless directed fibers.
This kind of directional system having endless fibers can be provided as a mesh system
like a woven or knitted system or the like in the abovementioned polymer matrice.
[0022] It turns out that in a particular preferred development the container well's edge
is preferably integrally moulded with the container well. Also, alternatively or additionally,
a container door's edge is integrally moulded with the container door, In each case
the edge moulded integrally with the body (of the container well and/or the container
door) turns out to be particularly advantageous. The development has the advantage
that a sufficient stress resistance is provided to the door and/or the container well
by means of the integrally moulded edge. Additionally, particular advantageous, the
opening function of the container, i. e. release of the container's door from the
container's well, in an emergency situation turns out to function easy and safe even
upon stress or pressure load on a container's side walls in an arrangement of a number
of oxygen supply devices in the ceiling-panel along the aircrafts cabin.
[0023] In a particular preferred embodiment the container has a front, rear and side container
wall and the container well's edge has a rear edge on a rear container wall and a
front edge at the front container wall and a side edge at the side container wall.
In particular the first side wall to a forward side adjacent container and/or a second
side wall to a backward side adjacent container in an arrangement of adjacent containers
have a side edge. At least the side edge is bead to form an edge bead. Thereby, in
particular forward side and backward stress and pressure is safely released and a
safe opening operation of the container door from the container well is guaranteed
in an emergency situation. Unwanted jamming of door and well is avoided, even upon
stress or pressure exposure.
[0024] In a preferred development the container has front, rear and side container walls
with wall regions and transition regions there between wherein at least one wall and/or
transition region has a reinforcing depressions, in particular on the front and rear
container wall, in particular depressions extending into the container well's edge.
It can be advantageous but not necessarily to provide at least one wall and/or transition
region with reinforcing depressions. When providing reinforcing depressions it turns
out that depressions extending into the containers well's edge, in particular into
the containers well's side edge are particular preferred.
[0025] Nevertheless particular advantageously it turns out that by using a sheet-moulded
compound material of the concept of the invention at least one wall of the container
well and/or container door can be formed to have a wall thickness of below 2 mm, preferably
below 1 mm. This is particular preferred to further decrease the weight of the container.
Thus in a very preferred development all walls, that is the front rear and both side
container walls have a wall thickness of below 2mm, preferably below 1 mm.
[0026] In a particular preferred variant of the aforementioned development it turns out
that the container well's edge has an edge material thickness and a container walls
transition region has a transition region material thickness. The variant preferably
provides that the edge material thickness and/or the transition region material thickness
is at least partly larger than the wall thickness; in particular at least partly larger
than a thickness of 2mm, preferably larger than a thickness of 1 mm. The development
recognized that --by providing thicker container well's edge and/or container walls
transition regions-- the stress and pressure resist of the container can be advantageously
improved. Following the concept of this development, if provided, also the reinforcing
depressions advantageously have a depression material thickness wherein the edge material
thickness is a larger than the wall thickness.
[0027] In a particular preferred development for providing the aforementioned development
the composite of thermoset sheet material based on fiber reinforced polymer matrices
has large thickness regions and low thickness regions. The respective regions in the
development are arranged such that for moulding a container wall's edge material thickness
and/or a container wall's transition region material thickness and/or a reinforcing
depression material thickness is thicker than the container wall's thickness, in particular
thicker than 2 mm, preferably thicker than 1 mm.
[0028] The aforementioned concept of the development provides a particular preferred synergy
of manufacturing process by using a preferred half product of SMC material variation
in thickness of the regions.
[0029] For a more complete understanding of the invention, the invention will now be described
in detail with reference to the accompanying drawing. The detailed description will
illustrate and describe what is considered as a preferred embodiment of the invention.
It should of course be understood that various modifications and changes in form or
detail could readily be made without departing from the spirit of the invention. It
is therefore intended that the invention may not be limited to the exact form and
detail shown and described herein, nor to anything less than the whole of the invention
disclosed herein and as claimed hereinafter. Further the features described in the
description, the drawing and the claims disclosing the invention may be essential
for the invention considered alone or in combination. In particular, any reference
signs in the claims shall not be construed as limiting the scope of the invention.
The wording "comprising" does not exclude other elements or steps. The wording "a"
or "an" does exclude a plurality. The wording ,"a number of" items, comprises also
the number one, i.e. a single item, and further numbers like two, three, four and
so forth.
[0030] The drawing shows in:
- Fig. 1
- a particular preferred embodiment of a container for an oxygen supply unit having
different thickness regions resulting from different thickness regions of the half
product of sheet-moulded compound material.
- Fig. 2
- an example of an oxygen supply device having an oxygen supply unit and a container
of Fig. 1.;
- Fig. 3
- a particular preferred embodiment of a system of an arrangement of containers --here
a number of oxygen supply devices-- in a ceiling-panel along an aircrafts cabin --here
along an aircrafts cabin alley of seats-- wherein each oxygen supply unit is stored
in a container of Fig.1.
[0031] Fig. 1 shows a container 10 for an oxygen supply unit as shown in the system 20 of
Fig. 2. In the system 20 an oxygen supply device having an oxygen supply unit 30 and
the container 10 of Fig. 1 is provided. The oxygen supply unit 30 can be an oxygen
pressure cylinder or a chemical oxygen generator. Also the oxygen supply unit 30 can
be a chemical oxygen container combined with an oxygen pressure buffer and a downstream
connected electronic or mechanical flow regulator.The container 10 of Fig. 1 has a
container well 1 and a container door 2 and a hinge profile 3 which on the one hand
is adapted to keep the door on top of the well during usual flight conditions and
on the other hand for safe opening during hazardous situations when needed.
[0032] Also, according to Fig. 3 the hinge profile 3 is adapted for assembling the container
10 into an arrangement 100 of a number of containers 10.i --this means containers
10.1, 10.2 and so forth until 10.n according to a predetermined number n-- for a ceiling-panel
along an aircrafts cabin. Thus the arrangement 100 of containers 10.1 to 10.n is for
providing an arrangement of a number of oxygen supply devices like the one shown as
system 20 in Fig. 2 along an aircrafts cabin alley of seats. As shown by the hinge
bar 11--for cooperation with hinge openings 12 and hinge openings 13 in the hinge
profile 3-- the container door 2 is pivotably joint at a container well's edge 4.
As recognized by the inventive concept the containers well's edge 4 establishes not
only sufficient stability to the container well 1 of Fig. 1 as such and thus to the
container 10 but also to an arrangement 100 of containers 10.1 until 10.n of Fig.
3 even when subjected to considerable stress and pressure load along an aircraft cabins
elongate axis above an alley of seats. Thus the edge 4 functions as a stabilising
frame for the container 10 as such. Also the edge is a load deducting element upon
arrangement of the container 10 in the arrangement 100 shown in Fig. 3.
[0033] In the present embodiment the container well 1 with the container well's edge 4 the
container door 2 with the container door's edge 5 and the hinge profile 3 consists
of a sheet-folded compound material SMC. SMC is moulded from a composite of thermoset
sheet material based on fiber-reinforced polymer matrices mainly.
[0034] In the instant embodiment the polymer matrices is an unsaturated polyester resin
but in a variant also can be based on epoxy or also silicone, melamine, phenolic,
polyimide and other resin systems. Generally these kinds of resins provide for a wide
range of electrical, mechanical and thermoinsulating applications. In particular also
flame retardant and heat resistant applications can be provided. In particular it
turns out that upon providing a fiber-reinforcement to the polymer matrices this results
in a high mechanical strength composite material being of high temperature and chemical
resistance. The SMC is best-suited for static dissipation of stress and pressure as
demanded for the instant container for an oxygen supply unit as such and for arrangement
in a number of oxygen supply devices of Fig. 3.
[0035] In a varied embodiment the container 10 of Fig.1 and the containers can 10.i of Fig.
3 can be adapted such that a passenger appliance is stored in the container. Thus
the number of containers 10.i can form an arrangement of a number of oxygen supply
devices as shown in Fig. 3. Also additionally or alternatively the number of containers
10.i can form a number of passenger supply units or a number of passenger supply devices
as claimed in one of claims 15 or 16. Then the oxygen supply unit 30 of Fig. 3 could
be replaced by a passenger appliance --like an oxygen supply unit, oxygen masks, warning
lights, reading lights, airjet nozzle alone or in combination-- and/or an oxygen supply
unit, i.e. in an integrated or segregated configuration. In particular an arrangement
of containers for oxygen supply units can be adjacent to or combined with a panel
or another arrangement of containers for passenger supply units.
[0036] Generally a sheet-moulded compound is manufactured by dispersing long length fibers
with a length greater than 1 inch; here the fibers are chopped glass fibers on a bath
of polyester resin. The longer the glass fibers in a sheet-moulded compound the better
are strength properties of the SMC as compared to standard bulk-moulded compound products
BMC. During the manufacturing process a reservoir dispenses a measured amount of specified
resin paste onto a plastic carrier film for example. This carrier film passes underneath
a chopper which cuts the glass rowing onto the surface. Once these have drifted through
the depth of the resin paste another sheet is added on top which sandwiches the cast.
The sheets are compacted and then entered onto a take-up roll which is used to store
the product while it matures. A carrier film is then later removed and the material
is cut into charges. Depending on what shape is required determines the shape of the
charge. Generally sheet-moulded compound benefits from a very high volume production
ability, excellent part reproducibility and cost efficiency.
[0037] In the present embodiment a directional long fiber version of sheet-moulded compound
material is used wherein rather long directional fibers are used to form a mesh like
system. The mesh like system can in particular also use a woven or knitted system
of fibers in a variant. For increasing mechanical strength of the container well 1
and container door 2 both edges, namely container well's edge 4 and container door's
edge 5 are integrally moulded with the body of the container well and the container
door respectively.
[0038] The container well in particular has a front, rear and side container wall 1.1, 1.2,
1.3, 1.4 and a floor 1.5 respectively. In the present embodiment a front edge 4.1,
rear edge 4.2 and side edges 4.3, 4.4 are formed by integrally moulding the edges
4.1 , 4.2, 4.3, 4.4 with the container well walls. Thus this results in a very high
stabile version of the container well 1. In particular, on all the aforementioned
sides the container edge 4 has an outer edge portion 4A extending crosswise from the
walls and an inner edge portion 4B which smoothly extends from the outer edge portion
4A into the wall 1.1, 1.2, 1.3, 1.4 respectively. Thus also this construction increases
static stability of the container. Moreover this construction is adapted to be easily
produced within a thermoforming assisted deep-drawing moulding process for the sheet-moulded
compound material SMC.
[0039] Also in the present embodiment in the transition regions 5.1, 5.2, 5.3, 5.4 between
the walls 1.1, 1.2 , 1.3 , 1.4 depression regions are provided to further increase
the static stability.
[0040] In a particular preferred variant of this embodiment the walls can be produced with
a wall thickness well below 2 mm, preferably well below 1 mm, whereas the regions
of edge transition have material thicknesses which are above a wall material thickness,
in particular above a thickness of 2mm, preferably above a thickness of 1 mm. Thus
without increasing the weight of the container considerably these statically sensitive
regions are further stabilized by an increased wall thickness of the light weight
sheet moulded compound material. Thus the static stability of the container 10 is
drastically increased without considerable increasing the weight.
[0041] As it is to be understood the instant embodiments can be well produced from a composite
of thermoset sheet-material based on fiber-reinforced polymer matrices which have
large thickness regions and low thickness regions. The regions are arranged such that
--after moulding-- a container well's edge material thickness and a container well's
transition region material thickness and reinforcing depression material thickness
as outlined above is thicker than a container wall's thickness. In particular in the
present embodiment this means that the large thickness regions are assigned to the
edge 4 , the depressions and the transition regions 5.1, 5.2, 5.3, 5.4 as outlined
before. The low thickness regions are addressed to the regions of the walls 1.1, 1.2,
1.3, 1.4 as outlined above.
[0042] Thereby as such stable and also in an arrangement 100 a container 10 with high stress
resistance is provided by the concept of the instant invention and as described in
the aforementioned embodiment. In particular opening of the container door 2 is guaranteed
even upon mechanical load or a hazardous impact on the container 10.
