Definitions
- the present invention is directed to some improvements to an emergency shelter and more particularly to some improvements to the emergency shelters comprising an inflatable envelope for lodging and safeguarding a plurality of persons in an ambient pollutted by gas or noxious substances dispersed in the atmosphere or the like.
- the known device comprises a base and an impermeable envelope variously folded upon itself in rest condition and then spread out upward by an inflatable element to delimit an air-tight room inside of which a plurality of persons can be lodged.
- the device avails itself of suitable means to permit the breathing, for example breathing masks distributed inside the shelter associated by two corrugated hoses to the inhalation and exhalation valves applied on their turn to the envelope walls.
- the device comprises also special means to establish an overpressure inside the shelter, for instance a pedal bellows or a fan or a compressed air bottle connected by the ducts to the inhalation filters associated to the envelope walls.
- This device is intended to constitute an emergency shelter, easily transportable with a helicopter into a pollutted zone, where after having been let down with a rope is automatically inflated and becomes a temporary shelter for safeguarding a plurality of persons.
- the known emergency shelter is satisfactory, of simple and prompt utilization and generally suitable for civil and/or military uses.
- the present invention aims at providing an emergency shelter devoid of the previously cited drawback which is contemporaneously of simple manoeuvrability and rapid use.
- the object of the present invention is an emergency shelter for use in an ambient pollutted by gas, noxious substances dispersed in the atmosphere and the like, said shelter comprising a base and a deformable envelope of impermeable plastic or elastomeric material forming the walls of the shelter, at least one opening on the shelter walls and means for closing in a tight manner said opening, said envelope being inflatable from a first configuration according to which it results to be folded upon itself to a second configuration corresponding to a space closed among the base and the walls for lodging a plurality of persons, said shelter being characterized by the fact that the envelope comprises superimposed sheets sealed to one another along two pairs of sides, the sides of the two pairs being substantially transversal to one another, said superimposed sheets originating a closed air space inflatable with a fluid under pressure, means being provided for feeding fluid at the air space between the superimposed sheets and means for regulating the overpressure of the fluid in said air space with respect to the ambient outside the shelter.
- the shelter is characterized by the fact that the ends of the superimposed sheets of the envelope are associated to supporting elements formed by inflatable tubular elements of impermeable material.
- the shelter supporting structure can be formed by any whatsoever number of inflatable tubular elements and assume shapes and dimensions as desired, for example the shelter could have a half-circle cross section with supporting elements extending circumferentially between the opposite sides of the base or a polygonal section with supporting elements formed by a plurality of consecutive rectilinear portions extending between the opposite sides of the base or a rectangular section with the supporting elements perpendicular to one another forming the lateral walls and the roof or in general other shapes, such as a pyramid, conic or truncated-cone shape.
- reference numeral 1 represents an emergency shelter for use in ambients pollutted by gases, such as yperite or poison and pollutant gases, substances injurious to breathing or aggressive to skin dispersed in the atmosphere or gas exhalations caused by fires and working irregularities in a production cycle near a factory.
- gases such as yperite or poison and pollutant gases
- the emergency shelter 1 is apt to lodge a plurality of persons protecting their safety from the pollutant effects of the outer ambient.
- the shelter 1 comprises a base 2 and an envelope 3 sealed at the base.
- the envelope is of impermeable plastic or elastomeric material to be inflated from a first configuration where it results to be folded upon itself to a further configuration corresponding to a space closed between the base and the wall for lodging a plurality of persons.
- the envelope 3 is made of rubberized fabric, in particular a fabric comprising synthetic fibers of nylon or polyester or aramidic fibers associated to synthetic elastomers, in general rubber materials impermeable to particular gases depending on the ambient conditions that it is wished to face.
- the base 2 could be formed by a rigid layer made impermeable by means of a suitable covering or, according to other solutions, the base could be formed by inflatable elements, as for instance a pneumatic bottom.
- the envelope 3 comprises a suitable opening (not shown) and means of closing in a tight manner the opening, both explained hereinafter.
- the envelope 3 comprises a supporting structure formed by a first plurality of inflatable tubular supporting elements or pillars 4 distanced from one another and extended circumferentially and by a second plurality of inflatable tubular supporting elements 5 disposed both in central position and at the sides of the envelope on the base 2.
- the tubular elements have the double function of forming the supporting structure and spreading out the envelope 3 according to its final shape when a fluid under pressure is supplied inside them.
- the inflatable tubular supporting elements 4 protrude from the lateral ones 5 on the base and converge on the supporting elements 5 arranged in central position.
- the various supporting elements forming the supporting structure have independent chambers and are then connected to one another at the relative crossing zones through jointing means or adhesives of known type, as the dashed line of figure 4 shows.
- the essential characteristic of the present invention consists of arranging at least two sheets of rubberized fabric 6 and 7 superimposed one upon another (figure 3) and sealed at the ends between pairs of opposite sides.
- the first pair of sides is constituted by adjacent tubular elements 4 and the second pair is constituted by tubular elements 5, central and lower on the base 2, respectively.
- the two sheets 6 and 7 are joined in such a way as to originate an air space or bag 8, delimited by substantially transversal sealing lines; the air space is inflatable by supplying its inside with a suitable fluid under pressure, for instance air.
- the areas 9, 10, 11, 12 delimited by tubular elements perpendicular to one another are formed by superimposing two sheets which give rise to a number of air spaces equal to the cited areas or a single air space if the outer sheet is sealed only at the ends reducing the four areas to only one area.
- the envelope comprises front parts 13 and 14, each of which can be formed by at least two superimposed sheets originating an air space filled with a fluid under pressure likewise what already described and shown in figure 3.
- the two parts 13 and 14 can be approached or moved away through a zip-fastener or by making recourse to the adhesive operation of the lips with known systems.
- the emergency shelter 1 comprises means for feeding fluid under pressure, for instance air, either at the tubular elements 4 and 5 and the envelope 3 and also at the various air spaces 8 between the superimposed sheets 6 and 7.
- means are provided to regulate the pressure of the fluid in the air spaces 8 with respect to the ambient outside the shelter.
- the means for feeding the fluid are realized through a compressor 13′ arranged on the base 2 and a generating set (not shown) arranged outside the shelter and connected to the compressor through a suitable circuit.
- the compressor could be placed outside the shelter.
- the compressor 13′ is connected by means of a hose 14′ to a suitable filter 15 associated to the envelope walls to inhale air from the outer ambient.
- the compressor 13′ through the hoses 16 sends air already filtered to the envelope inside and through the hoses 17, 18, 19 sends air both to the inflatable tubular elements 4 and 5 and to the air space 8.
- hoses for the tubular elements and the air spaces are in a number corresponding to the various independent chambers to be inflated.
- the means for regulating the air overpressure in the various air spaces 8 are constituted by valves 20 and 21, inlet valve and air valve, of known type, suitably calibrated to permit the air to escape outwards or to get into the air space so as to have always an overpressure with respect to the outer ambient, preferably of 0.01 atm.
- breathing masks provided with inhalation and exhalation hoses; the ends of said hoses are associated either to an inhalation valve unit and relative filter or to the exhalation valve.
- the valves of the masks are applied to the walls of the envelope.
- the envelope inside can be provided with a plurality of zones independent of one another used for the decontamination of suits used by the staff for various interventions outside the shelter.
- the invention achieves the aimed purposes.
- the principle of the invention is based on the contemporaneous presence of a plurality of barriers of different type, each one opposing any possible penetration of gas or other pollutant substances from outside to inside of the envelope.
- a first barrier of mechanical type is constituted by the outermost sheet.
- a second barrier this of pneumatic type, is formed by an air breath under overpressure towards the outer ambient.
- This pneumatic barrier is determined by the two sheets 6, 7 filled with a fluid maintained by the calibration of the inlet and air valves at an air pressure sufficient to push back the gases and the pollutant substances at room pressure.
- a third barrier is of fluid-mechanics type and is originated by the fact that the volumes involved in the air spaces between the superimposed sheets are small, so that through small inlet and air valves in each air space it is possible to make a frequent change of air. In practice there is a continuous air washing inside the air spaces, with the advantage of expelling constantly possible small pollutant traces which have overcome the first and second barriers.
- a four barrier, of mechanical type is then represented by the innermost sheet of each air space.
- the invention permits to have a considerable increasing of the resistance of the envelope walls so that they can support the possible accessories present inside the shelter, as for example high capacity filters for a fan, valves for different breathing masks, suction hoses, electric parts for the connection with the outer generating set.
- the cited optimal result is due to the fact that the overpressure inside each air space 8 places under tension the various fabrics originating in practice a kind of stiffening useful to the just cited purposes.
