DE102018004683A1 - Device for rescuing people from high-rise buildings and high-rise buildings during fires and disasters - Google Patents

Abstract

The device is used to rescue people from high-rise buildings and high buildings in case of fire and disasters, where the maximum reach of firefighters and similar devices is exceeded. On the basis of well-known parachutes designs have been developed for such cases, but where there is a risk that at relatively low bounce heights, the screen opens too late, only partially or not at all. On the negative side, there is a very high level of mental inhibition, because the person leaving the danger spot with the unopened umbrella is virtually lost.
These problems are solved by the device. To rescue people in the above-mentioned danger cases is an at least double-walled parachute or parachute (Fig. 2, Pos. 3), the intermediate space (7) is filled with light gas. The filling from a pressure vessel with light gas (8) is triggered by a start button (10) and is controlled by means of an automatic control valve (9). After the completion of the filling process, the screen has an upwardly directed curvature, similar in shape to known parachutes and having a similar carrying capacity like this. By filling with light gas there is a buoyancy of the screen of a few kN so that the screen (3), connected by the tethers (11) with the person to be rescued (1), is in a limbo. The person to be rescued (1), for these visibly and tangibly connected to the open and above her floating screen (3), now jumps into the open (in the rescue zone) and slides with the screen (3) down.

Description

Technical task and objective

The device is used to rescue people from high-rise buildings and high buildings in case of fire and disasters, where the maximum reach of firefighters and similar devices is exceeded. On the basis of well-known parachutes versions have been developed that can be used in case of fire, but with these there is a risk that at relatively low jump heights, the screen opens too late, only partially or not at all. There is also a very large psychic inhibition threshold in such umbrellas, because the jump of the rescuing person from the point of danger with unopened screen is virtually in the void. The solution described eliminates these disadvantages.

Solution of the problem or technical task

To the rescue of persons ( 1 ) in the above danger cases, a parachute or a paraglider, externally similar with known gliders and parachutes. As a solution example serves a variant with paraglider, in the 1 to 3 pictured is. Unlike the conventional screens, in the described solution, an at least double-walled screen ( 2 respectively. 3 ) used in its space / cavity ( 7 ) At a given time, a light gas filling is introduced. The filling of the cavity ( 7 ) with light gas takes place from a pressure vessel ( 8th ) - if necessary, several containers can be used - the one on the screen ( 2 respectively. 3 ) is attached. The filling process with light gas from the pressure vessel ( 8th ) via an automatic control valve ( 9 ), with which this is equipped. To trigger the filling process, a start button ( 10 ) connected to the control valve ( 9 ) is attached. Before the start of the filling process, the folded, unfilled screen ( 2 ) in the immediate vicinity of the person to be rescued ( 1 ). The on the screen ( 2 respectively. 3 ) attached tethers ( 11 ) on the body of the person to be rescued ( 1 ) attached. Then the start button ( 10 ) of the automatic control valve ( 9 ) and immediately thereafter the still unopened and unfilled umbrella ( 2 ) into the open (in the planned rescue zone) and now hangs with his weight on the straps ( 11 ) between the person to be rescued ( 1 ) and the screen ( 2 ) are attached. Still during the dropping of the screen ( 2 ) the shield cavity ( 7 ) with light gas from the pressure vessel ( 8th ) to fill. Thanks to the corresponding design of the internal connecting elements ( 6 ) and the construction of the upper shield sheath ( 4 ) and the lower shield sheath ( 5 ) and their peripheral pressure-resistant connection with each other, bulges through the filling of the screen ( 3 ) upwards, similar in shape to known gliders or parachutes, where he has a similar carrying capacity like this. The amount and pressure of the light gas filling, the size and the cut of the screen are designed so that the screen ( 3 ) in filled condition, one for the person to be rescued ( 1 ) Powerful completely controllable buoyancy of a few kN has. The completion of the filling process of the umbrella ( 3 ) is also carried out by the automatic control valve ( 9 ). The person to be rescued ( 1 ), for them visible and felt via the straps ( 11 ) with the umbrella open and floating above it ( 3 ), now jumps into the open (into the rescue zone) and glides with the umbrella ( 3 ) downward.

field of use

Rescue of persons in case of fire and catastrophes in skyscrapers and in high buildings.
