FIG. 6 is an operation explanatory view of the drive device 6 provided on the four sides of the outer peripheral wall 2c. As shown in FIGS. 1 to 4, the supporting member 6a is inserted into the through hole 2e formed in the outer peripheral wall 2c, and the horizontal support shafts 7a and 8a provided on the supporting member 6a are connected to the upper locking member 7 and the upper locking member 7, respectively. The lower locking member 8 is rotatably attached. The pair of left and right upper locking members 7 are connected to the actuator 9 through the rod 7b, and are normally engaged with the locking groove 4b of the protective frame 4 when the actuator 9 is activated. As shown in FIG. 4B, the protective frame 4 is rotated and disengaged from the locking groove 4b, and the protective frame 4 biased by the spring 5 projects upward from the support frame 2. On the other hand, the lower locking member 8 has the center of gravity set so as to perform a pendulum motion when the protective frame 4 is lifted to support the lower end portion of the protective frame 4 as shown in FIG. 4B. Is. It should be noted that the above-mentioned means for urging the protection frame 4 composed of the spring 5 and the engagement / disengagement means for the protection frame 4 composed of the drive device 6 constitute the driving means in the present invention.

As shown in the figure, the control device 10 connects the actuator 9, the seismic sensor 11, and the manual switch 12 to an AC power source, and has a backup means 13 such as a battery that operates at the time of power failure. There is. The seismic sensor 11 is attached to the support frame 2, for example, and when a predetermined shake is detected, the relay contacts 11a,
It is configured to close 11b. The seismic sensor 11 has a mechanical type in which a metal ball pops out of a recess to close the contact point due to vibration, a piezoresistive type,
A well-known acceleration sensor such as a piezoelectric element type is used in combination with an amplifier.

When 1 detects the shaking exceeding the specified value of the house, the actuator 9 operates based on the signal from the seismic sensor 11 (in this example, the relay contact is closed and current flows),
The upper locking member 7 rotates by being pulled by the rod 7b and disengages from the locking groove 4b, and the protection frame 4 biased by the spring 5 projects upward from the support frame 2. On the other hand,
The lower stopper 8 rotates by its own weight and supports the lower end of the protective frame 4. That is, the protective frame 4 is held at the upper position.

By the way, a house may be damaged by a typhoon,
Since the approach of typhoons can be expected, the manual switch 12
By operating (see FIG. 5) and lifting the protective frame 4 in advance, it is easy to ensure safety.

前述の実施例と同様の構成である。Next, another example of the disaster prevention bed will be described. The disaster prevention bed 21 includes a support frame 22 and a bed portion 2
It is a separate body from 3. Therefore, it is sufficient to surround the ready-made bed as it is with the frame-shaped support frame 22, and the bed can be easily installed. The protective frame 24 and the driving means for lifting the protective frame 24 have the same configuration as that of the above-described embodiment.
