Description

  The present invention relates to a bed excellent in safety during a disaster or the like.

  Japan is an earthquake-prone area, and disaster prevention education has been conducted for the public for a long time. In addition, concrete measures such as strengthening earthquake resistance of buildings against earthquakes that are currently unknown will occur. Efforts to take countermeasures are underway. However, such a seismic strengthening measure is not so widespread due to various circumstances such as the cost of seismic renovation, especially in ordinary houses.

  On the other hand, based on the fact that the Great Hanshin-Awaji Earthquake (January 17, 1995) occurred at 5:46 am before dawn, it is difficult to evacuate to the outside immediately in a panic situation immediately after getting up. From the point of view, it is effective to evacuate under the seismic reinforced bed, and there is an advantage that the seismic reinforcement of the bed itself does not require much cost. In other words, as a specific measure for seismic reinforcement, it is very effective in terms of safety and cost to use a seismic strengthened bed. In the meantime, the following are disclosed as beds that can protect themselves in the event of an earthquake.

  For example, in a bed that evacuates under a bed in the event of an earthquake, a bed frame having a loading strength of 2 tons or more, a plurality of columns provided on the side of the bed from the bed frame, and upper and lower ends of the column are connected. There is disclosed a bed with a shelter for earthquake evacuation that is composed of a frame member and a lower frame member and does not provide a support column in the vicinity of the center of one side of the bed provided with the plurality of support columns and serves as an entrance to the bottom of the bed. (Patent Document 1).
