RU218270U1 - FIRE RESCUE DEVICE - Google Patents

Abstract

The device for rescuing people in case of fire belongs to the field of rescue service and is designed to protect people from fire and smoke during a fire before the arrival of rescue services and measures to ensure the evacuation of people to a safe area. Device for rescuing people in case of fire, containing a folding structure, consisting of hinged fasteners, placed in an unfolded position inside the window opening in the form of a window opening trim, and in the unfolded position, during a fire, is a sealed chamber, the frame of which is made of non-combustible heat-resistant elastic material, while the chamber is placed on a platform made of non-combustible material, and on one of the hinges there is a telescopic ventilation duct, which extends through the opening in the wall beyond the fire source and the smoky zone, while the duct is equipped with an air-forcing device that creates inside the chamber overpressure that protects against smoke entering the chamber during a fire, which allows people placed inside the device to provide protection from fire and smoke during a fire before the arrival of rescue services and measures to evacuate to a safe area.

Description

The device for rescuing people in case of fire belongs to the field of rescue service and is designed to protect people from fire and smoke during a fire before the arrival of rescue services and measures to ensure the evacuation of people to a safe area.

Devices are known for rescuing people from multi-storey buildings during a fire, which are folding structures placed in window openings (utility model patents RU 118674, RU 107263), containing a working platform, hinged fasteners that allow you to transfer the platform to the working position, and cables, holding the folding structure in the unfolded position.

The disadvantages of such devices include poor protection against fire and smoke coming from the lower floors of a burning building.

The task to be solved by our proposal is the development of a device that increases the efficiency of protecting people from fire and smoke.

The technical result is achieved by the fact that the device, containing a folding structure, consists of hinged fasteners, is placed in an unfolded position inside the window opening in the form of a window opening trim, and in the unfolded position, during a fire, is a sealed chamber, the frame of which is made of non-combustible heat-resistant elastic material, while the chamber is placed on a platform made of non-combustible material, and on one of the hinges there is a telescopic ventilation duct, which extends through an opening in the wall beyond the fire and smoky zone, while the duct is equipped with an air-injecting device, which allows you to create excess pressure inside the chamber, which protects against the ingress of smoke into the chamber during a fire. The possibility of creating a sealed chamber with fresh air injection makes it possible to protect the people inside it from fire and smoke damage during a fire before the arrival of rescue services and measures for evacuation to a safe area.

The technical result is illustrated by drawings:

figure 1 - view of the device in the off position;

figure 2 - view of the device in the rescue mode in case of fire;

in Fig.3. - sectional view of the device.

The device for rescuing people in case of fire contains platbands-clamps 1 holding a frame 2 consisting of metal strips 3 with hinged fasteners 4 covered with non-combustible heat-resistant elastic material 5, on the floor in the area of platbands-clamps 1, considering them in the unfolded state of the device, there is a platform from tile 6, and in the lower part of the wall with a window opening, inside the zone of the folding structure, there is a telescopic ventilation duct 7, on which there is an air blower 8, which provides air flow into the chamber from the zone outside the building and, accordingly, outside the fire.

The use of the device is as follows: during a fire, people in the room equipped with the device enter the platform of tile 6 and lower the frame 2 due to the hinges 4 so that the trim-clamps 1 fall close to the surface of the tile 6, while metal strips 3 and non-combustible heat-resistant material 5 create a sector-shaped zone that prevents people from contact with fire and smoke, and through the telescopic air duct 7, thanks to the air-forcing device 8, clean air is supplied from the zone outside the fire, which prevents the penetration of smoke.

Claims (1)

A device for saving people in case of fire, containing a folding structure, characterized in that it consists of hinged fasteners, placed in an unfolded position inside the window opening in the form of a window opening trim, and in the unfolded position, during a fire, is a sealed chamber, the frame of which is made from non-combustible heat-resistant elastic material, while the camera is placed on a platform made of non-combustible material, and on one of the hinges there is a telescopic ventilation duct, which extends through an opening in the wall beyond the fire and smoky zone, while the duct is equipped with an air-injecting device , which allows you to create excess pressure inside the chamber, which protects against the ingress of smoke into the chamber during a fire.
