In addition to the protective plate (15), a sheet, an auxiliary material (17) such as a net may be attached to each primary and secondary shelter surface. As shown in Fig. 2, when folding a foldable telescopic seismic shelter, both variable long sides (2) are extended so that both central long sides (3) are raised. In the case of the bedding (13), the bedding (13) can be accommodated in a state in which the center of the bedding (13) is lifted by the central rotation shaft while the bedding (13) is laid on the secondary shelter surface in the horizontal lower part. It is possible to save space by eliminating the need for taking in and out of the bed and the bed (22).

It moves on the high-strength rail (20) in a falling-off prevention state. Regarding the load applied to the upper secondary shelter surface, it is responded by the tensile stress of the variable long side (2), but for the purpose of reinforcement, it is a high-strength pillar-shaped middle pillar (21) that connects the connecting material (19) up and down and is expandable. Is provided to cope with the load from the upper part and also to prevent falling from the secondary shelter surface during sleep. Further, the tops of both the middle pillars (21) on the parallel primary shelter surfaces are connected by a high strength horizontal member (26) by rigid joining. The structure of expansion and contraction of the middle pillar (21) is the same as the variable length side (2) of the center lifting type except that there is no spring, and the middle pillar (21) has the minimum length when used and is fixed in length to correspond to the compressive force. Secure with the stopper (10). Regarding the secondary shelter surface, it is constituted by a parallel rotation axis (1) connecting the corresponding pins (4) on the outer periphery of the parallel primary shelter surface and the variable long side (2) of the unit.

As shown in FIG. 4, this is an example in which several types of ramen bodies (7) are used and screws (8) are used as media in combination with columns (9) to be used inside a building. Since the building is constructed so that it can be displaced and endured to some extent during an earthquake, a clearance with the building should be provided for installation. The auxiliary material (17) is more finely fixed to the rubber cushion material between the members by tightening with strong bolts or the like to reduce the gap between the members, and other sheets such as the protective plate (15) may be attached. . The telescopic seismic resistant shelter may be used outdoors. 3) Above, all types of telescopic seismic shelters. Steel is used as the high-strength material used for the main part.
In the case of both types of folding telescopic seismic shelters, there are cases in which a desorption device that prevents the shelter body from collapsing due to an earthquake during folding is firmly attached to the building. In all cases, there is a case where the box containing the supplies prepared for an earthquake or the like is set in a place where the safety of the shelter body is not impaired.

[0007]

As described above, the present invention has the following effects. 1) Since the folding type telescopic seismic resistant shelter uses the triangular principle that is difficult to deform, it can be folded because one side is expandable while having high strength, and the bedding (13 ) Bedding (13)
The bed (22) is not needed because it is folded without putting in and out, and it is possible to save space and protect from earthquakes and the like. 2) Assembled telescopic seismic shelter has screws (8)
Since the members are assembled in the medium, it can be disassembled and carried in, and it is easy to adapt to the shape inside the building, as well as the folding type, not only from the collapse and scattering of furniture and the like caused by the earthquake, but also from the collapse of buildings. Increase the possibility of protecting life and property. In addition, it is often difficult to firmly attach furniture collapse prevention equipment to a building, but in the case of an assembly type telescopic seismic resistant shelter, structural members are exposed, so auxiliary members (17) are used to make them robust. Can be attached to. 3) Collectively, the telescopic seismic shelter can open a new world in the field of protection from earthquake disasters.
