When fixing to the slab floor 12, move the adjusting leg 10 to the position of the supporting leg 13, then lower the adjuster 11 until the caster 9 leaves the free access floor 14, and in this state couple the adjusting leg 1o and the supporting leg 13. 15 prevents the casing 1 from moving or falling during an earthquake or the like.

[Problems to be Solved by the Invention] According to the structure of conventional storage device installation, when an earthquake or the like occurs, the housing 1 is fixed to the slab floor 12 via the legs 16, so that it does not fall over. Although this can be prevented, the vibration of the slab floor 12 is directly applied to the casing 1 via the legs 16, which increases the shaking of the casing 1.

For this reason, there have been problems such as the mechanism deck 3, which is housed within the housing 1 and is susceptible to vibrations, is likely to be damaged.

This invention was made in order to solve the problem described in 1. This invention is a storage device that can prevent the storage device casing from vibrating and overturning during earthquakes, etc., and does not damage the mechanical deck inside the casing. Installation consists in obtaining the structure.

[Means for Solving the Problems] A substrate is provided opposite to the bottom side of the storage device housing, legs are provided on this substrate, and a vibrator made of an elastic material is provided between the bottom of the housing and the substrate. An absorbing part was interposed.

[Operation] In the event of an earthquake, etc., the storage device housing is fixed to the floor via the legs, so it will not fall over, and the vibration absorption section absorbs vibrations and shaking from the floor, reducing the vibration of the housing.

Reduce shaking.

[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to FIGS. 1 to 9. Incidentally, the same or equivalent parts as in the conventional example shown in FIGS. 10 to 12 are given the same reference numerals, and the explanation thereof will be omitted.

In each time, 20 is a board arranged so as to face the bottom surface 1a of the housing 1, and a vibration absorbing section 21 is interposed between this board 20 and the bottom surface 1a of the housing 1, and the bottom surface 20a of the board 20 is is provided with leg portions 16 and casters 9, 9, . . . as in the conventional case. As shown in FIG. 4, the vibration absorbing section 21 has a two-stage structure in which a ring-shaped elastic member 23 is interposed between two disc metal fittings 22.
1 lower disk metal fittings 22, 22 through rivets 1 to 24.
...is connected to... 1. A hole 22a formed in the diameter of the head 24a of the rivet 24 is provided on the periphery of the disk metal fitting 22.
22b formed on the bolt diameter of rivets 1 to 24 is 1
6 pieces are formed at predetermined intervals every other day, and correspondingly 6 pieces are formed downwardly through the upper and lower surfaces around the elastic member 23.
Through holes 23a facing the hole 22a and 23b facing the hole 22b are formed. This elastic material 23 is sandwiched between the upper and lower two disc metal fittings 22 and 22, and the rivets 1 to 24 are inserted through the holes 22a of the second disc metal fitting 22, and their tips are inserted into the holes 22b of the lower disc metal fitting 22. Then, insert the rivets 1 to 14 through the open holes 22a of the lower disk metal fitting 22 and fix their tips to the holes 22b of the disk metal fitting 22 below. The vibration absorbing portion 21 is formed by stacking these in two stages. Incidentally, the through holes 23a and 23b are formed with step portions 23s as shown in FIG. 22 will not leave. Bolt holes 22p, 22p at the center of the disk metal fittings 22 and 22 on the upper and lower sides of the vibration absorbing section 21 are provided with mounting holes 1 to 25°25, so that the disk metal fittings on the second side 22 is attached to the bottom surface 1a of the housing 1, and the lower disk metal fitting 22 is attached to the substrate 20.

Next, the operation will be explained based on FIGS. 5 to 9.

For example, if a horizontal shaking earthquake occurs, the
As shown in the figure, the substrate 2 is fixed to the slurry floor 12 side.
0 shakes horizontally, but since the vibration absorbing section 21 absorbs this horizontal shaking vibration, the horizontal shaking vibration of the housing 1 is attenuated. In addition, even in the event of a direct-type (vertical shaking) earthquake, the vibration absorbing section 21 expands and contracts in the upward direction, as shown in FIGS.
- Suppresses downward vibration. Further, as shown in FIG. 9, for example, the vibration absorbing section 21 on one side is expanded by the maximum expansion dimension h1,
Even if the casing is tilted by 0° in a state where the other vibration absorbing part 2 is shrunk by the minimum shrinkage dimension h2, the center of gravity G1 of the casing and the perpendicular line GIG2 to this center of gravity G1 are Case 1 unless moved outward from center position J
In fact, the two housings 1 will not fall over.

Therefore, the mechanism deck 3 in which the housing 1 is housed can be protected from vibrations and overturning during an earthquake.

Although the vibration absorbing section (1) has a two-stage structure, it may have a one-stage or two-stage or more structure, and the shape may not be ring-shaped but may be other shapes.

[Effects of the Invention] As explained above, according to the present invention, a substrate facing the bottom side of the storage device housing is provided, the leg portions are provided on this substrate, and the bottom surface of the housing and the substrate are connected. Since a vibration absorbing section made of an elastic material is interposed between them, it is possible to prevent the storage device casing from vibrating and overturning during earthquakes, etc., and the storage device can be installed without damaging the mechanism deck inside the casing. can get.
