Paper-made composite furniture

Abstract

Paper-made composite furniture comprises at least two connection tubes and at least one spacer that are coupled together. Each connection tube is a hollow tube with an inner side made of stiff paper and an outer side made of smooth paper. The connection tube has at least one latch groove. The spacer is a solid panel made of stiff paper with the outer side coated by smooth paper. The spacer has two sides wedged in the latch grooves of the connection tubes. The stiff paper has characteristics to withstand greater loading and pressure, thus can replace the conventional furniture made of woods, plastics or metal. The invention not only can reduce material, transportation and assembly costs, also can reduce environmental pollution and facilitate carrying and assembly during outing. The smooth paper can be formed with colors, patterns or texts, thus can provide greater visual appeal and ornamental efficacy.

What is claimed is: 
     
         1 . A paper-made composite furniture, comprising at least two connection tubes and at least one spacer coupled together, wherein:
 each of the at least two connection tubes is a hollow tube including an inner side made of stiff paper and an outer side made of smooth paper, and at least one latch groove; and   the at least one spacer is a solid panel made of stiff paper coated by smooth paper at an outer side thereof and includes two sides wedged respectively in the latch grooves of the connection tubes.   
     
     
         2 . The paper-made composite furniture of  claim 1 , wherein the connection tube includes a first extension section and a second extension section at two sides of the latch groove, the first extension section being formed at a width smaller than that of the second extension section. 
     
     
         3 . The paper-made composite furniture of  claim 1 , wherein the connection tubes and the spacer are respectively formed by compression of multi-layer stiff paper and multi-layer smooth paper. 
     
     
         4 . The paper-made composite furniture of  claim 1 , wherein the stiff paper is sand tube paper and the smooth paper is kraft paper. 
     
     
         5 . The paper-made composite furniture of  claim 1 , wherein the surface of the smooth paper is formed with colors, patterns or texts. 
     
     
         6 . The paper-made composite furniture of  claim 1  further including a plurality of corner joints to couple with the connection tubes.
