Problems solved by technology

[0004] At the same time, there are also a small number of escape umbrellas in the market. Chinese patent 201810459320 discloses "Emergency Escape Umbrella Cover for High-Rise Buildings". function, but the time required for the canopy to inflate is too long, so it is not suitable for the escape of trapped persons in middle and high levels

Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] combine Figure 1 to Figure 4 , a rapidly inflatable escape airbag umbrella, comprising a canopy, a bottom airbag 6, a safety belt, an inflation device, several annular airbags 5 and several cylindrical airbags 4. The diameters of several annular airbags 5 decrease successively from top to bottom to form a bowl shape, so as to increase the windward area. The uppermost annular airbag 5 communicates with one end of several cylindrical airbags 4. The vertices of all cylindrical airbags 4 share a circle, and the diameter of the circle is 4m. The bottom airbag 6 communicates with the lowermost annular airbag 5, and the inflation device is used to inflate the annular airbag 5, the cylindrical airbag 4 and the bottom airbag 6. The canopy is positioned above the annular airbag 5, and the canopy is fixedly connected with some cylindrical airbags 4.

Abstract

The invention discloses a rapidly inflatable airbag umbrella for safe escape, which is suitable for the escape of middle and high-level trapped persons, and comprises an umbrella cover, a bottom airbag, a safety belt, an inflation device, several annular airbags and several cylindrical airbags. The diameters of several annular airbags decrease sequentially from top to bottom to form a bowl shape to increase the windward area. The uppermost annular airbag is connected to one end of several cylindrical airbags. The lowermost annular airbags are connected, and the inflation device is used to feed the annular airbags, cylindrical airbags and bottom airbags. The canopy is located above the annular airbags, and the canopy is fixedly connected with several cylindrical airbags. The invention adopts a plurality of annular airbags superimposed to form a bowl shape, which ensures the lift force at the moment of falling, and increases the windward area during the falling process. The adjacent annular airbags are partially connected, and the remaining non-connected parts can realize elastic shock absorption during landing.

Description

technical field [0001] The invention belongs to escape equipment, in particular to a rapidly inflatable airbag umbrella for safe escape. Background technique [0002] With the development of the economy, high-rise buildings stand tall in cities, and high-rise fires have become a major hidden danger that threatens life safety. As far as the current situation is concerned, the main method after a fire is to escape the danger through the escape channel, but for the trapped people at high levels, this method is time-consuming and laborious, and it is prone to smoke poisoning, and the safety factor is low. Therefore, windows have become a common escape port for escape from high-rise buildings, and the escape tool that circulates more in the market is the rope escape device. [0003] Chinese patent 201811223628 discloses "A Descending Device for High-rise Escape". When in use, the Descending Device is fixed by a safety hook, the rope passes through the Descending Device in a cert...
