FR2608200A1 - Portable mobile shelter for instantaneously putting personnel fighting forest fires to safety - Google Patents

Abstract

The subject of the invention relates to a portable mobile shelter for instantaneously putting personnel fighting forest fires to safety. It consists of a folding lightweight enclosure which is transportable and fireproof and is combined, firstly, with a structure for instantaneously opening out for installation, then of openings with rapid-action leaktight closing members 10, 11, 12 and an observation window 20 containing an air reserve 16 which can be used at will. It is intended to enable a team which finds itself far away from its base to shelter temporarily and immediately in the event of a sudden change in wind direction, from a burning environment or from smoke.

Description

 The object of the invention relates to a portable portable refuge for the instantaneous security of personnel fighting forest fires.

 It is intended to allow a team far from its base to temporarily and immediately take shelter in the event of a wind change, incandescent environment or smoke.

 Experience has shown that during forest fires, forward combat stations are not always able to fall back to safety positions and, in practice, there is no effective way to protect themselves. suffocating fumes or renewing an overheated atmosphere, moreover the swings of wind or other more or less anarchic and unpredictable turbulences too often causing the death of the advanced teams which did not have time to take shelter.

 The device according to the invention eliminates these drawbacks and allows an individual or a team to take his service equipment with him to ensure very quickly not only protection from the thermal effects developed by a fire, but still fumes, toxic gases and fleeting and unstoppable high temperatures, it also allows, in addition to preservation, safety with respiratory rescue and service elements in the event that the critical situation continues.

 It is made up of a light, foldable, transportable and flame-retardant capacity - combined first with an instant deployment structure to be put in place, then by quick-sealing shutter openings and observation window containing a reserve of usable air. the command.

In the accompanying drawings, given by way of nonlimiting example of one of the embodiments of the subject of the invention
to the; Figure 1 shows the refuge seen in perspective and as a whole.

 Figure 2 is a view of the same object in its folded position.

 Figure 3 shows in elevation and in section the refuge with its incorporated elements of survival and rapid deployment.

 Figure 4 is a plan view from above of the refuge.

 The refuge, Figures 1 to 4, is formed by four triangular walls 1, 2, 3, 4 giving it a regular pyramidal shape.

 These walls are reinforced by light tubular metal frames 5, 6, 7, 8 connected to their upper part and articulated on a circular flange 9.

 The walls are made of fireproof material such as asbestos. The front face 1 has an opening 10 with hooking lining and receiving velvet 11, 12 so as to obtain a tight closure instantly put in place.

 A thrust spring 13 with arm 14, 15 spacers ensure the immediate displacement of the rigid mounts 5, 6, 7, 8 and the spreading of the bottom 23.

 A flexible return cable 22 connected to the bottom 23 and to the flange 9 supports a bottle of so-called service compressed air 16.

 Handles 17, 18 facilitate transport or hanging. A strap 19 allows folding under a small footprint and prevent the unexpected opening of the shelter.

 Instant deployment and quick folding is facilitated by the return cable 22.

 The space is provided for four occupants. The transparent skylight 20 in treated glass makes it possible to check the external condition or follow the development of the incident.

 A safety pouch 21 can be provided to contain dressings or first aid remedies.

 This refuge, worn on the back of a man on the scene of advanced forest fire fighting, provides individual or team security threatened by flames, smoke and others, when they cannot fall back or be rescued.

 Shelter times being very short make it possible to ensure security in all places and to withstand very high temperature waves without the slightest attack and to resist any asphyxiating thermal attack for very long times thanks to the emergency air 16.

 In any case, this portable refuge is an element of security that can be used in spaces that had not been protected until today and that led to the death of forest firefighting personnel.

 However, the shapes, dimensions and arrangements of the various elements may vary, as indeed the materials used for their manufacture within the limit of equivalents without changing for this, the general design of the invention which has just been described.
