The bag (2) is located either in a housing in a recess (12) of the transport or directly in the recess, the housing or recess being closed by a cover (5). A protrusion (4) of the cover (5) is located in an extension (13) of the recess (12) and can be gripped by a user. The bag (2) is attached to the housing or the transport (11) and to the cover (5). In use, the cover (5) can be moved from the closed configuration shown to an open configuration in which the bag or rupturable membrane (2) is ruptured to release the respiratory apparatus. <IMAGE>

Description

SPECIFICATION Emergency respiratory equipment This invention relates to emergency respiratory equipment.
Emergency respiratory equipment can have a housing or stand-by container which contains a respiratory protective apparatus which is kept in readiness as an emergency device. For this purpose, the equipment hangs permanently on the wall of a rest room at the disposal of people to be protected in cases of emergency. The construction and hanging of the housing should be such that the respiratory protective apparatus can be removed without difficulty by unpracticed people, as is absolutely necessary in cases of disaster, i.e. in the dark for example.
Our British Patent Specification 2,030,869A describes known emergency respiratory equipment.
A housing for a respiratory protective apparatus comprises two housing members which can be formed as bowls, and contains, as an escape device, for example, a respiratory protective apparatus in a bag made of material impervious to vapour. The bag entirely encloses the respiratory apparatus and can be ripped open. The equipment can be hung up in hotel rooms by way of a wall attachment in a first rear housing member. The type of wall attachment is such that the equipment cannot readily be detached and removed from its intended location. Both members of the housing are held together on one side by means of a hinge joint and on the opposite side by means of a ratchet locking device.The front housing member enables a safe opening to be made by means of a holding plate or protrusion disposed on the side of the ratchet shutting device, so that the housing can be opened by a one-handed operation in an emergency. The bag, which is connected to both housing members by way of a respective ripping flap or strap, is ripped open upon opening the housing. Thereby, the respiratory protective apparatus lies ready for use in front of the user.
A mounting of the housing on the wall of a transport vehicle is disadvantageous due to the restricted space available there, particularly in the case of aircraft. The housing protrudes into the available space and disturbs the passengers. A particular danger also lies however in the possibility of damage to the housing thus rendering it unserviceable. They must be arranged in such a way that they can be easily grasped and are capable of function in all circumstances.
A known oxygen-emergency supply system is described in US Patent Specification 3,615,250 and is intended for aircraft passengers. It comprises a central electrical monitoring and release arrangement and supply devices affixed thereon, each supply device being adjacent to a group of seats. Each supply device is planned to supply, on average, three passengers and contains, alongside a common chemical filling with chemically bound oxygen, the respiratory masks for the passengers which are connected by way of flexible supply lines. The supply devices are housed in stand-by state above the seats behind doors in the inner wall of the cabin. The doors open downwards. When the doors are opened, the respiratory masks hanging on their lines fall into a zone in reach of the passengers. The other parts of the device, connected to the release arrangement, remain in their place.In an emergency, the electric releasing arrangement causes the oxygen filling to ignite or start generating oxygen and the doors to be released.
It is disadvantageous that the respiratory masks remain connected to other parts of the device which stay fixed in their place and that consequently the passengers can only be supplied as long as they remain in their places. These devices provide no help in the case of an escape of poisonous gases. It should also be borne in mind that in the case of fire, the use of oxygen is possibly dangerous.
It is desirable that a stand-by container or housing for respiratory protective apparatuses which are wall mounted in aircraft should make an economical use of space available. The equipment should also be such that all bulkiness is avoided. The necessary, and at all times sure accessibility, must be guaranteed for the people to be protected in every event.
According to the present invention there is provided emergency respiratory equipment mounted in a transport, the emergency respiratory equipment comprising: a respiratory apparatus; a rupturable membrane which hermetically encloses the respiratory apparatus, is mounted in an aperture or recess within the transport, and is attached to the transport; and a cover which, in a closed configuration, is located in and closes off that aperture or recess, and which is attached to the rupturable membrane and has a manually grippable protrusion which is located in an extension of said aperture or recess; the arrangement being such that, in use, the protrusion can be gripped and moved by a user to bring the cover into an open configuration thereby causing the rupturable membrane to be ruptured to release the respiratory apparatus.
In the present invention, the term "transport" is intended to include, for example, ships, aircraft, hovercraft and vehicles.
The respiratory protective apparatus can be arranged set back into the wall of an aircraft or other transport. It requires no additional room and remains nevertheless accessible, as is necessary for a respiratory protective apparatus which is particularly needed in emergencies.
The cover can be flush with a surface in which the recess or aperture is formed.
The emergency respiratory equipment is preferably mounted inside an aircraft cabin, and the aperture or recess and the extension of the aperture or recess is then provided in a lining of the aircraft cabin.
In one embodiment of the present invention, the rupturable membrane and the respiratory apparatus are housed in a housing comprising said cover and a base, which base is mounted in said aperture or recess, the rupturable member being attached to the base and to the cover.
In a second embodiment ofthe present invention, the lining is provided with a recess and an extension of that recess, and that recess, together with the cover, forms a housing forthe rupturable membrane and the respiratory apparatus, the rupturable membrane being attached to the portion of the lining defining the recess and to the cover.
In a third embodiment of the present invention, the lining is provided with an aperture defined by a rearwardly extending the lip of the lining, and the rupturable membrane and the respiratory apparatus are disposed at least partially in the aperture, with the rupturable membrane being attached to the lining and to the cover.
In a fourth embodiment of the present invention, the emergency respiratory equipment is mounted in an aperture or recess, in a cover member of a back of a seat, with the extension of the aperture or cover also being provided in said cover member. The seat can be an aircraft seat.
The rupturable member is conveniently attached to the transport and to the cover by straps.
For a better understanding of the present inven- tion, and to show more clearly how the same may be carried into effect, reference will now be made, by way of example, to the accompanying drawings, in which: Figure 1 shows a vertical section through a respiratory apparatus in a housing in an aircraft cabin wall; Figure 2 shows a vertical section through a respiratory apparatus in a housing whose base portion is formed by a cabin wall; Figure 3 shows a vertical section through a respiratory apparatus in a housing mounted directly in a cabin wall; and Figure 4shows a vertical section through an aircraft seat, in which a respiratory apparatus in a housing is mounted.
Referring to Figure 1, a respiratory protective apparatus is housed in a stand-by container or housing 1 comprises two half-housings or bowls, namely a base 3 and a cover 5 which is provided with a protrusion 4, to be held or gripped by a user. A bag 2 is connected by way of a front ripping strap 7 to the cover 5 and by a rear ripping strap 8 to the base 3.
Thus, the bag 2 is ripped open when the stand-by container 1 is opened by rotating the cover 5 anticlockwise about a hinge between the lower edges of the base 3 and the cover 5. The respiratory apparatus can then be picked up by a user.
Figure 1 shows a sunken stand-by container or housing 1 mounted in an aircraft cabin wall with the respiratory protective apparatus inside. The aircraft cabin wall comprises a metal outer skin 9 and an insulating layer 10 which then defines one side of an insulating cavity 17 in addition to the cabin interior lining or casing 11. The stand-by container 1 is mounted in a recess 12 of the lining 11 flush therewith. The protrusion or plate 4 is readily accessible by means of an additional recess or extension 13.
In Figure 2 an embodiment is shown in which the base 3 of the housing 1 is dispensed with. Here, a base of the recess 14 in the casing 11 takes the place of the base 3. The cover 5 covers the base of the recess 14. The rear ripping strap 8 is directly connected to the base of the recess 14.
In the embodiment shown in Figure 3, the base 3 is dispensed with completely. There is an aperture 15 in the casing or lining of the cabin wall. The cover 5 covers the aperture 15. The lining 11 has a rearwardly extending projection or lip 16.
Figure 4 shows an arrangement of a stand-by container or housing 1 in the cover member of a back rest 18 of an aircraft seat. A rear wall 20 of the backrest has a recess 21 which is closed by a cover 5. The recess 21 extends into an additional or extension recess 22 so that a protrusion 4 of the cover 5 can be gripped by a user. The bag 2 enclosing the respiratory apparatus is enclosed in the recess 21 by the cover 5.
