The installation method is also very simple. Further, since the lifesaving frame for collapse of a house according to the present invention uses compressed air, it is easy to handle. For example, if air gradually escapes during installation over a long period of time, new air may be supplied by an inflator for automobile tires or the like, and even if a failure should occur, it will cause air leakage. There is no danger of getting the room dirty.

If, instead of a bed, for example, an art object, a figurine, a bookcase or the like is accommodated in the space surrounded by the support pipes of the lifesaving frame according to the present invention, these can be removed from falling objects caused by house collapse. Can be protected. That is, the life-saving frame according to the present invention can be widely used as a protection frame against the collapse of a house due to an earthquake, in addition to the purpose of protecting human life while sleeping.

[0024]

As described above, according to the present invention, even when a house is collapsed due to a large earthquake while sleeping, a fixed object that can avoid direct hits of falling objects above the bed can be avoided. Since the space is secured, a person can be prevented from being directly hit by a falling object and being laid under the falling object, and human life is reliably protected. Further, according to the present invention, it is possible to prepare for an earthquake easily at a very low cost as compared with a method of strengthening the earthquake-resistant structure of a house.
