Abstract

FIELD: rescue equipment, applicable in creation of equipment for rescuing of people mainly at fires. SUBSTANCE: the pneumatic base is made of isolated sections. The pick-up canvas is fastened on the upper side of the base. The base is made of two, spaced apart in height, closed in a ring, pneumatic shells and a pneumatic shell enveloping them. The enveloping shell is fastened with the shells closed in a ring. Belts with a low relative elongation are fastened uniformly in height on the lateral surface of the enveloping shell. The shells that are closed in a ring may be made of hermetically isolated sections. Interconnected pneumatic cylindrical shells converging to the center may be fastened on the upper, closed in a ring, shell, on the inner side. EFFECT: enhanced reliability in use. 3 cl, 2 dwg

Description

 The invention relates to rescue equipment and can be used to create equipment for saving people during fires.

 Known life-saving rescue canvas, created by the company "Vento", designed for emergency rescue of people during fires in buildings, as well as in other emergency situations when other methods are not possible (journal "Civil Protection" N 9, 1999, p. 39). The canvas is held by rescuers in the amount of 16 people. The reliability of salvation in this case is associated with the actions of each of the 16 rescuers.

 Known rescue cushion designed to pick up jumping or falling persons from tall objects in case of fire (A.S. N 1386210).

 The disadvantage is similar to the previous device: the operation of the pillow, including pumping of inflatable bags, requires numerous personnel. In addition, the presence of hard covers on the receiving surface can result in personal injury.

 Known rescue vehicles for jumping (German application N N 3516676, 383994, 3937399, 3937401, Japanese application N 3-63917). The devices have an identical design and include a frame holder made of inflatable sleeves, and a receiving canvas, tightening the frame holder. The disadvantage is that when a massive body falls onto a canvas, vertical inflatable racks can lose stability.

 As a prototype, a device for rescuing people from high objects (French patent N 1286282, A 62 B 1/22, 1962) containing an inflatable base made of insulated, ring-enclosed inflatable shells and a receiving canvas fixed to the upper side of the base was selected . When falling onto the peripheral part of the receiving canvas, rolling of the rescue from it is not excluded, which is a drawback.

 An object of the present invention is to increase the reliability of a device.

 The technical result is achieved in that in a device for rescuing people from tall objects, containing an inflatable base made of insulated, closed along the ring of inflatable shells, and a receiving canvas, the base is made of two inflatable shells spaced along the height and the inflatable shell covering them, while the enclosing shell is bonded with shells closed along the ring, tapes with a small elongation are fixed on its lateral surface, uniformly in height, and the upper part of the enclosing shell is with a receiving cloth.

 To increase reliability, inflatable shells spaced in height, closed in a ring, are made of sections hermetically isolated from each other.

 For the same purpose, inflatable cylindrical shells converging to the center and interconnected are fixed on the upper shell closed along the ring from the inside.

 A general view of the device is shown in FIG. 12.

 The inflatable base is made of an upper, ring-closed, inflatable shell 1 and a lower inflatable shell 2. On the upper, closed in a ring, shell 1, cylindrical shells 3 converging towards the center and interconnected are fixed 3. The upper 1 and lower 2 inflatable shells are covered by them an inflatable shell 4. The upper part 5 of the enclosing shell is at the same time the receiving canvas. To increase the rigidity of the side wall of the female inflatable shell 4, elastic bands 6 of material with a small elongation are fixed on it from the outside. The female shell 4 is bonded to the shells 1 and 2, closed in a ring.

 All inflatable elements of the device are made of rubberized fabric.

The device operates as follows. The sections of the upper 1 and lower 2 shells and the female shell 4 are connected through a manifold to a pressure source and pressurized. In this case, the sections of the upper 1 and lower 2 shells are inflated with a pressure exceeding the pressure in the cavity of the enclosing shell 4. The overpressure in the sections of the annular shells is ≈ 1 ... 10 kgf / cm ² , the pressure in the enclosing shell is ≈ 0.008 kgf / cm ² . This pressure distribution allows you to stretch the receiving canvas, as well as provide the inflatable base with sufficient rigidity, including the border area of the receiving canvas.

 Thus, the use of technical solutions will improve the reliability of the device to save people from high objects.
