Foldable device capable of being used as chair or desk

Abstract

The foldable device is used as a chair or a desk. The device has an upper plate and a lower plate. A supporting cloth is overlapped between the upper plate and the lower plate; the supporting cloth being flexible. The structure is divided into three parts, while the supporting cloth is not cut so that the whole structure is connected by the cloth. The foldable chair and desk combined device can be folded by folding from the cutting portions of the three parts. Furthermore, connecting sheets are formed on two supporting surfaces of the three parts, by connecting the connecting sheets, the foldable chair and desk combined device can be retained rigidly for bearing a heavy object.

Description

FIELD OF THE INVENTION [0001] The present invention relates to foldable devices, and in particular to a foldable chair and desk combined device, which can be made by only one plate without any further structure. No pivotal connection is needed in assembly. The present invention can be received in a paper box or within a car rapidly. BACKGROUND OF THE INVENTION [0002] The prior art chair or desk in picnic is made of plastics. The plastic chair (or desk) is light and small size, but it is unfoldable so as to occupy a great space. Furthermore, the thickness of the chair (or desk) is thin and thus cannot suffer from a great weight. [0003] Besides some chairs (or desks) are made of irons which is foldable so as to occupy a smaller space, but the chair (or desk) is heavy and thus it is difficult to be carried. Moreover canvas is used to fix the frame of the chair (or desk), but for a longer time, the canvas will be destroyed and the people sit thereon will feel uncomfortable. Thereby this...

AI Technical Summary

Benefits of technology

[0005] Accordingly, the primary object of the present invention is to provide a foldable device capable of being used as a chair or a desk, wherein the present invention can be made by only one plate without any further structure. No pivotal connection is needed in assembly. It is economic. the present invention can be received in a paper box or within a car rapidly.

Problems solved by technology

Besides some chairs (or desks) are made of irons which is foldable so as to occupy a smaller space, but the chair (or desk) is heavy and thus it is difficult to be carried.

Moreover canvas is used to fix the frame of the chair (or desk), but for a longer time, the canvas will be destroyed and the people sit thereon will feel uncomfortable.

Thereby this kind of prior art is not an ideal one.

It is difficult to be folded and thus is inconvenient to be carried out.
