For example, as will be described later, even if the floor 2 is placed on top of the support 1 to create a vibration-isolated structure, movement in all directions is possible, so lateral movement in all directions during an earthquake is possible. can be dealt with.

Next, an application example of this embodiment will be explained.

As shown in FIGS. 5 and 6, the floorboard 2 to which the support 1 of this embodiment is attached is formed to be smaller in size than the base surface 8 of the room 14. As shown in FIGS. That is, the floorboard 2 is formed to be smaller than the foundation surface 8 by, for example, 10 cm on each side so that the floorboard 2 can move horizontally relative to the foundation surface 8 during an earthquake.

A large number of supports 1 are attached to the lower surface of the floor plate 2, the number of which is sufficient to support the weight of heavy objects such as the computer 15 fixed on the floor plate 2, and the members 1a of the outer casing are fixed with bolts 7. do. This results in
The floorboard 2, the computer 15, etc. are constructed using a large number of small balls 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 5, 4, 5, 4, 4, 5, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4, 4 or or small small balls were interposed between the base surface 8 and the support surface 9...
It is supported so that it can move freely in the horizontal direction.

For example, in Fig. 1, when the foundation surface 8 moves from left to right as shown by the white arrow during an earthquake, each of the small balls 4, 4, etc. in contact with the foundation surface 8 rotates counterclockwise. The support body 1, which is in contact with the ball 4 through the support surface 9, moves relative to the left in the figure. At this time, the small balls 4, 4... move relative to the right with respect to the support surface 9, and enter the small ball storage space 10 on the right side in order starting from the rightmost small ball 4, and at the same time, the small balls on the left side The small balls 4 in the accommodation space 10 descend to the left end of the support surface 9 in order from the bottom and move so that the small balls 4, 4, etc. are always densely packed under the support surface 9. . The movement of these small balls 4, 4... is
Since this is carried out from the center of the support 1 all the way around in the horizontal direction, heavy objects such as the floorboard 2 and the computer 15 remain in a fixed position even if the foundation surface 8 moves horizontally in any direction during an earthquake. It is supported in a fixed state. Therefore, the safety of the computer 15 and the like is ensured.

In addition, the elastic dustproof cover 111 protects the small balls 4, 4.
This prevents dirt from entering the... area, so
The small balls 4, 4, . . . do not become immobile due to dirt clogging.

In addition, in order to prevent the small balls 4, 4, .

Further, a magnet may be provided above the member 1b of the outer casing so that the small balls 4, 4, . . . are attracted by magnetic force during transportation to prevent them from falling.

FIG. 7 shows another embodiment of the present invention, in which the support 1
It is formed by providing an outer case 16 that covers the outside of the. This outer case 16 is attached to the support body 1 so as to be able to move up and down slightly, and its bottom 16a prevents the small balls 4, 4, . . . from falling. Furthermore, since the outer case 16 houses the supporting body 1 so as to be movable in the horizontal direction, the outer case 16
6 is placed on the foundation surface 8 to enable its installation. Furthermore, since the outer case 16 also serves as a dustproof cover, the elastic dustproof cover 11 of the embodiment described above is unnecessary.

8 and 9 show still another embodiment of the present invention, in which members 1b of the outer casing of the support 1,
1c each having a circular cross section.
In addition, in order to prevent the small balls 4, 4... from falling during transportation, the side surface of the gutter-shaped cover 17, which has a U-shaped cross section and covers the entire lower surface of the support 1, is secured to the member 1b using set screws 18, 18. After the support body 1 is placed on the base surface 8, the setscrews 18, 18 are removed, and the cover 17 is slid to the front or back side relative to the plane of the paper in the figure and removed.
