Description

{A safe railing for apartment houses}

The present invention relates to a double safety guardrail, and more particularly, to a double safety safety guardrail for use in a residential area, which can be used as a user's escape route by simply changing the structure of the double safety guardrail to improve ease of use, The present invention relates to a double safety guardrail for a residential apartment which allows a neighboring household providing a space for evacuation to quickly recognize it, so that it can be safely used only for a purpose of use.

In general, fire in high-rise buildings such as apartments, townhouses and hotels is often difficult to evacuate.

Especially, when a fire occurs in a high-rise building and it can not escape through a door, there is a problem that it is entrapped in a room and suffocated in a smoke or exposed to a flame to suffocate.

As a solution to this problem, various emergency escape routes have been proposed, but most of these emergency escape routes have not been effectively used.

For example, Korean Patent Laid-Open Publication No. 10-2009-0042692 discloses an invention such as a "veranda safety rotating railing having a fire evacuation function", wherein the railing frame according to the present invention is installed in a direction toward the veranda, So that it can be turned and the other side can be opened.

Accordingly, when the railing frame of the present invention is opened and rotated at one end which is openable in the event of a fire or the like, the railing frame is rotated around one supporting column to move the other end to the outside of the building , So that a rope or a structure basket is installed in a railing frame which is distant from the outside of the building, and is structured to escape.

When a fire occurs, the railing frame according to the present invention is folded in a cantilever-like state in which one end is supported on a supporting column fixed to the veranda, and then hanged through a rope or a structural basket to the cantilever- In addition to not being safe, it is also structurally unstable. Moreover, hanging on a cantilever frame of a cantilever extending out into the air itself causes extreme fright.

On the other hand, the Korean patent application No. 10-2009-0037784, "Safety Railing for Fire Evacuation", is used as a safety guardrail of a veranda in a case where a railroad guardrail installed on a veranda of an apartment is made variable, and in case of emergency such as a fire, It allows the person to be transformed into a boarding gate to protrude to the outside of the veranda, allowing people to escape from the hot flame.

However, in the conventional safety railing for fire escape, the process of deforming the railing is troublesome and difficult to use.

In addition, a handrail having a fire escape function in the past has not been recognized by a generation providing a space for evacuation, which may be used as a means for intrusion.

Korean Patent Publication No. 10-2009-0042692 Korean Patent Application No. 10-2009-0037784
