Description

Protective guard capable of being unfolded into escape ladder

Technical Field

The utility model relates to a protective guard capable of being unfolded into an escape ladder.

Background

With the rapid development of cities and the urbanization construction of rural areas, it is a necessary trend that one-storey houses are gradually replaced by multi-storey and high-rise buildings. In order to prevent the theft of property, the installation of the anti-theft window is the simplest method for solving the problem. At present, the visible anti-theft windows on the market are all fixedly installed on the outer sides of the windows by expansion bolts after being integrally welded. However, once a natural disaster such as a fire or an earthquake occurs, the security window becomes the biggest obstacle for evacuation and escape and fire rescue, and thus, there are often cases of death and injury caused by the fact that people cannot escape. In order to prevent the tragic events, many local governments release regulations for prohibiting the installation of security windows in kindergarten and old care yard buildings, and twenty-eighth new fire laws officially implemented in 2019 countries further stipulate that: the doors and windows of the place with dense people can not be provided with barriers influencing escape and fire-fighting rescue. Therefore, irreconcilable contradictions occur between the anti-theft and emergency escape and the law compliance, and the national regulations related to the decoration of the building are difficult to control. Through carrying out patent inquiry to the relevant vocabulary entry of "burglary-resisting window of fleing" to learn, the one that has disclosed at present is: the surface of the anti-theft window is turned downwards to form a refuge area, and people can climb on the turned anti-theft window but cannot move downwards continuously. There is also a patent named as 'a high-rise escape burglary-resisting window', in which a rope barrel and a traction rope are installed above the burglary-resisting window, so that when an emergency occurs, a person climbs the burglary-resisting window, releases the traction rope, and can descend to a certain height, so that the person is far away from a dangerous area. The scheme has a complex structure, and the anti-theft window body can not rise to the original position after being released and can only be used once, and indoor personnel can not escape from the mechanism completely when more. There is also a patent named as 'an aerial ladder type refuge escape burglary-resisting window' which has no descending function at all, so that people can not be far away from dangerous areas, the refuge effect is not good, and people can not go to escape.
