FR2880648A1 - Safety device for creating survival zone in e.g. collective building, has foam pad dilating in order to couple imperfections of walls, ceilings and openings, blocking system against walls and ensuring sealing - Google Patents

Abstract

The device has a semi-rigid transparent panels (1) assuring planarity of the assembly, pneumatic reinforcing manifolds (2) and a foam pad (3). The pad dilates in order to couple the imperfections of walls, ceilings and openings. The pad is located in periphery of the assembly, blocks the system against the walls and ensures sealing. The outside of the pad in contact with the walls is equipped with a non-skid surface.

Description

The present invention relates to a public safety device and

  individual. It allows to quickly create, in collective or private buildings, a perfectly sealed survival zone, in case of:

  * Industrial disasters (toxic clouds) * Terrorism (chemical or bacteriological attacks) * Fires (intoxications by fumes) * Floods (water damage) This survival zone can be provided with an oxygen supply or 10 with breathable air, a certain amount of drinking water and an emergency care kit.

  In the current state of the art, the existing processes all have recourse to prior installations, wall fixings, mechanical reinforcements, various arrangements, often heavy, complex, long implementation. In the field of life-saving emergencies, these processes have serious shortcomings. In addition, in sealing effectiveness is not guaranteed.

  The device of the present invention makes it possible to remedy these problems. It is self-sufficient, portable and offers quick commissioning. It does not require any transformation or special arrangements of existing buildings. The device of the present invention makes it possible to close hermetically and according to the needs of the situation all or part of a building; corridors, access stairs, doorways and windows. Its design gives it excellent resistance to mechanical and chemical attack. The installation of the device does not require any particular professional skill. The implementation time of a device is two minutes.

  The accompanying drawings illustrate the invention: FIG. 1 represents the invention in front view. Figure 2 shows the invention in section A A '.

  The device of the invention is in the form of a flat, semi-rigid assembly (FIG. 1), the dimensions of which can vary according to the zone to be protected. This set consists of three groups of pneumatic elements, each ensuring a specific function and different from each other. - 2

  É The semirigid panels (1) ensure the flatness of the whole. They are transparent in order to limit the effects of claustrophobia of the people located inside the system as well as to allow a correct visualization, interior interior to possible rescuers.

  The pneumatic reinforcing tubes (2) are responsible for binding and imparting mechanical strength to the assembly. These pipes, under the effect of pneumatic pressure, behave in real struts and resist bending and buckling forces.

  É The waterproofing cushion (3), which is thinner than the pipes, has the capacity to expand significantly in order to match the imperfections of walls, walls, ceilings, embrasures, etc. The cushion is located on the outskirts of all, it is intended to block the system against the walls and ensures the étanchêitê.

  The outside of the cushion in contact with the walls has a non-slip surface (5) to optimize adhesion.

  The panels (1) and the reinforcement tubes (2) are in pneumatic connection and therefore support the same pressure. The sealing cushion (3) is pneumatically independent, its operating pressure is also lower than that of the assembly, Thus, the semi-rigid panels and the reinforcements tubes are reinforced with 350 to 450gr / cra2, the Sealing cushion is only reinforced from 150 to 200gr / cm2, The nature and. the thickness of the materials, under the effect of different pressures, react these elements, so that each of them fulfill their mechanical roles.

  The materials composing the entire system are assembled by thermo-fusion and gluing. They are non-flammable, resistant to acidic corrosion and protect against radioactive radiation.

  A system of two handles (4) is installed in the center of the device on the semi-rigid panels (1), At the rear of these handles and inside the panels concerned, are housed two reserves of compressed gas. One for arming the panels and tubings, the other for arming the sealing cushion. To ensure an immediate understanding of the operator, bright colors and different are adopted: Right handle and black sealing cushion, left handle and reinforcement pipes red, Both handles are each equipped with a manual trigger controlling the throttle.

  Thus, in case of emergency, only one person can seize the device, tearing its packaging to position itself in the middle of a corridor for example, grab the two handles, let go, deploy the device, activate the sending of the gases using the handles concerned and in less than two minutes the corridor is separated into two perfectly hermetic parts.

  According to the needs of the situation. as for the extent to be protected, several sets can be installed side by side.

Claims (3)

-4Claims   1) Pneumatic safety device, intended to ensure in an emergency the sealing of all or part of existing buildings, whether collective or individual; it is characterized by the transformation, under the effect of the pneumatic pressure, of an assembly consisting of panels (I), sufficiently rigid tubes (2) and a peripheral cushion (3) ensuring the sealing of the system.   2) Device according to claim I, characterized by a surfaceantidérapante located on the outside of the cushion whose area is in contact with the walls.   3) Device according to any one of the preceding claims is characterized in that the assembly is provided with two holding handles, provided with the triggering of gas.
