Desk with two desk plates

Abstract

A desk has double desk-plates and one of the desk-plate capable of being lengthening and shortening to adjust positions thereof. The desk has a larger main desk plate and a secondary desk plate smaller than the main desk plate. An overlapping three-dimensional space exists between the main desk plate the secondary desk plate. Besides, the main desk plate can be pulled out and overlaps the secondary desk plate. Not only a total area for arranging objects of the desk plate of the desk increases, but also the heights of objects arranged on the desk plates are not limited strictly. The desk also has a leg assembly for supporting the main desk plate, a removable shelf connecting to a bottom of the main desk plate, a fixing shelf for connecting the removable shelf and the leg assembly, a supporting stand for connection the secondary desk plate to the fixing shelf. The desk assembled by these components has spaces on the desk plate capable being used flexibly and adequately.
