Description

[0001]
[Field of the Invention]
The present invention relates to an electronic device shelf, and more particularly to a shelf capable of storing a plurality of electronic devices.
[0002]
[Prior art]
Various electronic device storage structures have been proposed for a structure that can be easily assembled without using a large number of connecting means such as screws, while having a robust structure that does not deform due to the weight of the electronic device (for example, , See Patent Document 1).
[0003]
In such a storage structure, in order to make the structure capable of storing electronic devices in two or more stages above and below, a chassis (which is disposed between the upper and lower electronic devices to ensure a certain strength) The bottom plate or top plate of the (main body) part must have a certain thickness. If this thickness is ensured, the chassis portion has a certain height higher than the electronic equipment to be accommodated. This becomes an obstacle to miniaturization of a storage structure such as a shelf. However, if the bottom plate of the chassis portion is made as thin as one steel plate or less, the bottom plate is deformed by the weight of the electronic equipment to be stored. Furthermore, problems will arise in terms of earthquake resistance.
[0004]
Also, in order to thoroughly reduce the size of storage structures such as shelves, it is desirable to omit the top plate, but if the top plate is omitted, the electronic device stored at the time of the earthquake will rattle and the electronic device It is possible that the operation will be hindered.
