Means for freely changing the mounting position of the shelves, such as these racks and storages, generally has locking holes for mounting shelves having different heights on the inner side surface of the rack or the like. A large number of means for selecting the position of the locking hole provided in advance are often used. That is, it is a means for locking an arbitrary coupling fitting or the like in the locking hole of a predetermined height, and mounting or locking the shelf plate on the coupling fitting.

[0004]

However, according to the conventional means for selecting an arbitrary height from a large number of locking holes, it is possible to install the shelves at the positions of the locking holes, but the shelves can be installed at the positions of the locking holes. It was difficult to make finer adjustments than the interval. For example, when using the locking holes that are arranged at 1 cm intervals,
The height can be adjusted in 1 cm increments, but there is the inconvenience that fine adjustment cannot be performed within 1 cm.

In a storage cabinet for storing integrated circuits and the like,
The circuit board is inserted between the upper and lower shelves, and this board is fixed sideways. Therefore, we have made it possible to finely adjust the spacing between the shelves, but this fine adjustment adjusts the position of the nuts screwed to the long bolts arranged in the height direction, and the shelves are moved through this nut. Since the fixing means is used, fine adjustment between the shelves is an extremely troublesome work.

Further, not only the above-mentioned storage but also a rack intended for general use such as an EIA standard 19-inch rack can be further adjusted by enabling fine adjustment of the shelf height. Since the usage is expanded, it has been desired to provide a device that can easily perform fine adjustment between shelf boards without being limited to a specific usage.

Therefore, the present invention has been devised to solve the above-mentioned problems, and is not limited to the preset adjustment interval of the shelf plate in all of the storage devices for detachably mounting the shelf plate. It is an object of the present invention to provide a shelf device for a storage device that enables fine adjustment between shelves and that can perform this adjustment work extremely easily.

By adjusting the distance between the top plate 1 and the bottom plate 2 with, the distance between the upper and lower shelving units mounted on the storage device P is finely adjusted.

The second means is to provide a column 4 that vertically penetrates the top plate 1 and the bottom plate 2, and to surround the column 4 with a coil spring 5.
And the elastic force of the coil spring 5 constantly urges the gap between the top plate 1 and the bottom plate 2 in the expanding direction.

The storage device P in the third means is a storage for storing the integrated circuit, the shelf device is made of a conductive material, and the ground path 6 is provided from the shelf device to the storage.

The storage device P in the fourth means is a 19-inch rack for storing computer-related equipment, which is a means for solving the problem.

According to the present invention, the thickness of the shelving device of the present invention is finely adjusted by adjusting the distance between the top plate 1 and the bottom plate 2 by the adjusting bolts 3, and the upper and lower shelves mounted at predetermined positions of the storage device P are adjusted. The distance between the devices will be finely adjusted. Further, the support column 4 penetrating the top plate 1 and the bottom plate 2 enhances the strength of the shelving device, and the coil spring 5 mounted around the support column 4 interacts with the adjustment bolts 3 to connect the top plate 1 and the bottom plate 2 to each other.
