- Devices apt to constitute an emergency shelter are already known, as for example that described in the Italian patent No. 1,161,847 of the same Applicant.
- 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.
- However, there are particular ambient circumstances where the high concentrations of noxious substances or of particular gases, as yperite or other war gases, require a still more advanced protection than that available up to now.
- In fact in the cited circumstances a permeability of the flexible layer forming the envelope could occur unavoidably little by little in the time with evident unacceptable drawbacks for the users of the shelter.
- Therefore 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.
- According to a preferred embodiment, 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.
- According to the cited embodiment 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.

- FIGURE 4 - is a partial top view of the supporting structure of figure 1.
- In figure 1
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. - 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 abase 2 and anenvelope 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.
- According to the preferred embodiment 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 according to some embodiments, 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 orpillars 4 distanced from one another and extended circumferentially and by a second plurality of inflatable tubular supportingelements 5 disposed both in central position and at the sides of the envelope on thebase 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. - As diagrammatically shown in figure 2, the inflatable tubular supporting
elements 4 protrude from thelateral ones 5 on the base and converge on the supportingelements 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 - The first pair of sides is constituted by adjacent
tubular elements 4 and the second pair is constituted bytubular elements 5, central and lower on thebase 2, respectively. - The two
sheets 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. - In practice, with reference to the figures 1 and 4, the
areas - Further, the envelope comprises
front parts - The two
parts - According to this solution any possible closing imperfection of the zip-fastener or of the lips already treated with the adhesive operation can be compensated with the overpressure realizable inside the shelter.
- The
emergency shelter 1 comprises means for feeding fluid under pressure, for instance air, either at thetubular elements envelope 3 and also at thevarious air spaces 8 between the superimposedsheets - Moreover, 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 thebase 2 and a generating set (not shown) arranged outside the shelter and connected to the compressor through a suitable circuit. - In alternative to what cited, the compressor could be placed outside the shelter.
- The
compressor 13′ is connected by means of ahose 14′ to asuitable filter 15 associated to the envelope walls to inhale air from the outer ambient. - Moreover the
compressor 13′ through thehoses 16 sends air already filtered to the envelope inside and through thehoses tubular elements air space 8. - Of course, the 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 byvalves - Inside the shelter, there are different means for the individual breathing, namely 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 large number of means to safeguard the plurality of persons can be of the type described in the Italian patent No. 1,161,847 of the same Applicant.
- Moreover, 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.
- In fact, 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 - 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.
- In particular the realization of the air spaces in which the two sheets have the maximum distance from each other comprised between 3 and 10 cm is advantageous.
- A four barrier, of mechanical type is then represented by the innermost sheet of each air space.
- Moreover 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. - Further it is evident how the stated solution has in combination with a high impermeableness to gases, the further characteristic of a prompt and easy use which derives from the presence of parts of impermeable elastomeric material suitable for an immediate inflation operation, in case also through bottles of fluid under pressure.
- Although some embodiments of the present invention have been illustrated and described, it is understood that the present invention includes in its scope any other alternative embodiment accessible to a technician of the field.
