[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seismic storage structure for a rack on which a measuring instrument, a small electronic device and the like are mounted.

[0002]

2. Description of the Related Art FIG. 4 is a front view of a conventional rack, FIG. 5 is a side view of FIG. 4, and FIG. 6 is a perspective view of a shelf plate of FIG.

[0003] As shown in each figure, a rack is a frame-shaped frame.
11 and a flat shelf plate 12 which divides the internal space into a plurality of upper and lower stages and is screwed to front, rear, left and right supports, and the shelf plate 12
A storage device 13 indicated by a two-dot chain line, for example, a measuring instrument or a small electronic device, is inserted from above and placed on the upper surface of the device. In addition,
Reference numeral 12a is a cable insertion portion for connecting the storage devices 13.

[0004]

However, according to the above-described mounting structure, there is no means for fixing the storage device on the upper surface of the shelf, and the frictional resistance between the shelf and the foot of the storage device is increased. In this case, there is a problem that the placed storage device may move sideways, fall off the shelf, and be damaged by vibrations such as earthquakes, since the storage device does not have an anti-seismic function to the extent that it prevents lateral displacement of the storage device. Was.

[0005] In view of the above problems, an object of the present invention is to provide a seismic storage structure of a rack in which storage equipment mounted on a shelf plate does not move due to vibration.

[0006]

In order to achieve the above-mentioned object, in a rack seismic storage structure of the present invention, a storage device mounted on at least one shelf plate constituting a rack and having a foot. A rear end regulating member movable in the front-rear direction of the rack, abutting on the rear end of the storage device and fixed to the shelf plate, and holding the foot of the storage device movable in the left-right direction of the rack. It is composed of a foot holding member fixed to the shelf, and a pressing member that presses the storage device toward the shelf and fixes it to the shelf.

[0007]

The rear end regulating member is in contact with the rear end of the storage device, and the foot holding member holds the foot so that the movement of the storage device in the front-rear direction and the left-right direction can be restricted. By pressing the storage device toward the shelf and fixing it to the shelf, the rise of the storage device can be suppressed.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The gist of the present invention will be described below in detail with reference to the embodiments shown in the drawings. FIG. 1 is a front view of the rack, and FIG.
1 is a side view of FIG. 1, and FIG. 3 is a perspective view of the shelf board of FIG.

As shown in FIG. 1 and FIG. 2, the seismic storage structure of the rack is made up of a frame-like frame 1 and front, rear, left and right side walls obtained by bending four edges of a square sheet metal into a frame as in the prior art. It comprises a flat shelf plate 2 on which the storage space 7 indicated by a two-dot chain line is placed by welding the front and rear columns 1a of the frame 1 to partition the internal space of the frame 1 into a plurality of upper and lower stages. The shelf plate 2 further differs in that it has a seismic storage structure including a rear end regulating member 3, a pair of left and right foot holding members 4 and a pressing member 5, as shown in FIG.

The rear end regulating member 3 is formed by bending a strip-shaped sheet metal having the same length as the width in the left-right direction of the shelf 2 into a right-angled L shape. 3a.
The rear end restricting member 3 is threaded with a nut (not shown) by passing the mounting screw 6 through a screwing means 10 pierced at the left and right edges of the upper surface of the shelf plate 2, that is, the long hole 2c-1 in the front-rear direction.

When screwing, the pair of left and right foot holding members 4 are fixed in advance, and the rear end regulating member 3 is moved and adjusted in the front-rear (depth) direction to accommodate the storage device indicated by the two-dot chain line. 7 and is screwed in a state where play of the storage device 7 in the front-rear direction is eliminated. Thereby, the movement of the storage device 7 in the front-rear direction is restricted.

Next, the pair of left and right foot holding members 4 have the same shape using a pair of left and right sides. The foot holding member 4 is formed by connecting the strip-shaped sheet metal at a right angle L.
It has a circular holding hole (through hole) 4a through which the right and left front feet 7a can be inserted among the feet provided at the four corners of the bottom surface of the storage device 7 at the tip of one of the bent pieces.

Immediately after the holding hole 4a, the holding hole 4a is bent in a Z-shape so that it can be inserted into a long hole 2c-2 in the left and right direction formed in the front edge of the upper surface of the shelf plate 2. Insert this Z-shaped bent part into a long hole 2c
The other bent piece is brought into contact with the inner surface of the front side wall 2a of the shelf 2 so that the other bent piece is inserted along the rear surface of the shelf 2 through the -2.

The screw means 10 formed in the bent piece, that is, a screw hole (not shown) is provided in the front side wall 2a of the shelf plate 2.
10 corresponds to the long hole 2c-3 in the left-right direction. The left and right pedestal holding members 4 insert the holding holes 4a into the left and right pedestals 7a on the front side of the storage device 7, and further insert the storage device 7 into the elongated holes 2c-2 on the upper surface of the shelf board 2. After being positioned substantially at the center of the shelf 2, the mounting screws 8 are passed through the long holes 2 c-3 on the left and right sides of the front side wall 2 a of the shelf 2, and are screwed into screw holes (not shown) of bent pieces on the back side. Thereby, the left and right movement of the storage device 7 is restricted via the foot 7a.

Next, the holding member 5 is a flexible band-shaped spring plate for holding the storage device 7 from above, and has screwing means 10, that is, a long hole 5a at both ends thereof. The long hole 5a has a length that can be adjusted to various heights of the storage device 7.

The holding member 5 is formed by screwing the holding screw 9 through the long hole 5a and the left and right side walls 2b of the shelf plate 2 while holding the storage device 7 from above. (Not shown). Thereby, the floating of the storage device 7 due to the vibration is prevented.

As described above, the front-rear direction of the storage device is regulated by the rear end regulating member, the left-right direction is regulated by the foot holding member, and the lifting of the storage device is regulated by the pressing member. It is possible to prevent the placed storage device from falling off the shelf board due to vibration such as an earthquake. Also,
Each of the screwing means of the rear end regulating member, the foot holding member, and the holding member with the shelf plate is formed into a long hole so as to be adjustable in the regulating direction, so that it can be screwed in accordance with storage devices of various dimensions. Can be.

[0018]

[Effect of the Invention] As described above, according to the present invention,
Since the storage device can be securely fixed to the rack shelf using the foot of the storage device, it contributes to the improvement of earthquake resistance and exhibits a very useful effect in practical use.
