Definitions

  • This invention relates to a collapsible anti contamination shelter particularly for protection against nuclear, biological and chemical substances.
  • the present invention seeks to provide a collapsible anti contamination shelter.
  • a collapsible anti contamination shelter comprising a totally enclosable air tight flexible structure, means for maintaining the structure in an erected state and an airconditioning system for the structure.
  • the airconditioning system includes a filter unit through which all the air entering the shelter passes for decontamination.
  • a hand operated, foot operated and/or electrically operated pump may be provided for sucking air through the filter unit.
  • the shelter may, when erected, be of generally rectangular shape and may be provided with attachment means in its upper part for attachment to supporting means such as the walls and/or ceiling of a room.
  • An airlock may be provided to allow entry to and exit from the shelter.
  • the shelter 1 shown in the drawings is intended for use inside a building so as to be supported by the building with a minimum of modification.
  • the shelter comprises an airtight cuboid having, for access, an airlock 2 at one end.
  • the walls 3 and roof 4 are suitably made of translucent polyurethene film, welded by radio frequency welding or adhered with suitable adhesives and may be reinforced as required.
  • the floor 5, which is sealed hermetically to the walls is made from a tougher form of the same material so as to take up the necessary wear which will take place in use. To this end, additional reinforcement may be added.
  • the structure of the shelter is supportable in eight places by fixings 5, shown in greater detail in figure 3.
  • the room in which it is to be placed must be suitably prepared beforehand.
  • the basic requirement is for hooks or screw eyes 6 to be located in the walls or ceilings to receive attachments 8 to be described in more detail hereafter.
  • the reinforcements may take the form of wooden joists e.g. 10cm x 10cm in cross section, which can be fitted above or beneath existing joists, preferably at right angles thereto.
  • the hooks may be attached directly to the existing joists.
  • the walls are concerned, if these are of brick then all that may be required is for the hooks to be fitted to wall plugs or the like located in the brickwork.
  • the fixing points may be in the form of threaded sockets, only the openings of which are visible, the hooks being in the form of eye bolts which are screwed into the sockets at the time of erection of the shelter.
  • the attachments 8 on the shelter itself are in the form of strengthening patches 9 to which a strap 10 is attached, the strap having at its free end a snap hook 11 which can be snapped quickly onto the eye 6 when erecting the shelter.
  • the strap 10 is preferably adjustable, for example, using a second strap 12 carrying a buckle arrangement 14 to which the first strap is buckled as shown in Figure 3.
  • attachments 8 may be provided, not all of which would be used in any one location.
  • a shelter which, when fully erected, would be larger than the room in which it is situated can be used by leaving portions of the shelter un-erected and folded, as will be hereafter described.
  • pressure relief valves 15 are provided which are so set as to ensure that a pressure in excess of atmospheric can be maintained in the shelter. In this way, should a small leak be accidentally found, all air flow would be from the shelter outwards so that no contaminated air could be admitted.
  • the pressure relief valves 15 are protected by wire cages 16.
  • the interior of the shelter has provided in it a single opening 17 in the form of closable flaps. These flaps are preferably secured in an airtight condition when closed by means of the sliding clasp fasteners 18.
  • This single opening 17 opens into the airlock 2 situated at one end of the shelter, egress from the airlock to the outside being through a second flap closure 20 on one side face 21 of the airlock.
  • This second closure 20 is also suitably closed by sliding clasp fasteners 22.
  • the airlock flap closure 20 comprises four parts 24 to 27 which are all "zipped" together in the closed condition.
  • the centre flap 24 is rolled up, the side flaps 25 and 26 are secured at the sides by ties 28 and the lower flap 27 lies flat on the floor.
  • each flap 30, 31 is provided in the manner of a tent opening, each flap having a centre fastening 33 (to the other flap) and floor fastenings 34.
  • the airlock suitably has its own frame 36 formed of metal structures which pass through sleeves 38 formed in the airlock material.
  • the airlock openings may be provided in both sides instead of only one as shown.
  • the airlock may have attachment straps 5 and its own pressure relief valve 15.
  • an air conditioning apparatus 46 comprising a filter unit 41 with an inlet opening 42 in the shelter wall and an outlet 43 to a pump 44.
  • This pump 44 sucks air through the filter 41 and passes it to an outflow pipe 45 to provide cleaned air to the interior of the shelter at 46.
  • a three stage filter is employed as the filter unit 41.
  • the pump 44 is a dual operation pump and is provided for both power and manual operation. To this end the pump 44 is provided with an electric motor (not shown) driven by a long life battery 47 and an operating handle 48 for hand operation.
  • the filter unit is preferably housed in a box structure 50, which is collapsible to allow it to pass through the airlock and the pump 44 is then mounted on a framework 51 attached to the top of the box 50.
  • the outlet from the pump 44 is branched to provide clean air along a duct 53 and this supply may be controlled by a valve (not shown) allowing the air to the airlock to be cut off.
  • the shelter is also equipped with looplines 54 along the walls for storage purposes and a special input socket 45 to enable a mains supply to be fed to the shelter (e.g. for operating the pump, electric motor and lights) if the mains supply is operating or during erection.
  • a mains supply e.g. for operating the pump, electric motor and lights
  • the shelter When the shelter is to be used in a room which is smaller than that for which it is basically designed, certain parts of the shelter may be left un-erected and the unused parts can be folded and covered by a cover flap 55 as can be seen in figure 4.
  • the shelter is carried by the four corner attachments, together possibly with the two outer central attachments.
  • the two corner attachments at the airlock end and the outer central attachment are used.
  • the inner central attachments and the inner end attachments adjacent to the airlock are used.
  • the shelter once erected can be to a large extent self supporting if there is a sufficient pressure differential between the interior and exterior.
  • the air pressure inside need only be slightly higher than atmosphere.
  • shelter can take many forms.
  • a rudimentary shelter could do without an airlock, but such a shelter would not be usable again once the door flaps had been opened to let people out.
  • An inlet for mains water to the shelter could be provided, should it turn out that the mains water was not contaminated. Provision for remote testing of the outside atmosphere could be included so that air could be tested without having to be introduced into the shelter. The same would apply to water.
  • a number of the materials used for the walls and ceiling could also be used, either a tougher form of the material being used or the material being reinforced or otherwise toughened.
  • airtight fastening could be used instead of or in combination with the sliding clasp fasteners for the entry openings.
  • velcro or like adherent fastenings could be used.
  • the airtightness could be achieved by seals which were separate from the actual fastenings.
  • the support attachments could take other forms, for example using chains, adjustment, if desired, being carried out by a similar system to the strap arrangement, replacing the buckle by a snap hook which could engage any of the links of the chain.
  • the whole shelter could be equipped with a de-mountable frame, for example similar to the frame provided for the airlock.
  • the filter system can be elaborated by the provision of a blast valve to protect the filters from over-pressure and a visual airflow indicator so that the operator of the pump can see readily that sufficient airflow is achieved. Means are provided to allow changing of the filter units if they should become clogged.
  • Pedal operation of the pump could be used instead of the hand arrangements and a hand or foot operated electric generator could be provided. If an exterior generator is available, this could have remote control operation and feed electricity into the shelter through the mains connection.
  • Additional means for exhausting air from the shelter could be provided for use in the event that the ceiling valves become blocked.
  • a carbon dioxide sensor could be incorporated in the installation to warn the occupants of the shelter to restart pumping of air and thus avoid the possibility of suffocation when the pump is not being activated all the time.
  • the shelter has been designed for lining an existing room, it would be possible to use such a shelter without the necessity of having a surrounding structure, where such a structure is not available, provided that sufficient toughness of the materials used is allowed for.
  • the shelter could also be used with an exterior metal framework such as a cage arrangement which could be assembled at any desired location.
