Inflatable product

Abstract

An inflatable product includes an inflatable body and a supplemental layer. The inflatable body includes a first wall and a first auxiliary sheet fused with each other. The supplemental layer is configured to cover the first wall and is fixed to the first auxiliary sheet of the inflatable body by sewing and/or gluing.

What is claimed is: 
     
         1 . An inflatable product, comprising:
 an inflatable body comprising a first wall and a first auxiliary sheet fused with each other; and   a supplemental layer configured to cover the first wall and fixed to the first auxiliary sheet of the inflatable body by sewing and/or gluing.   
     
     
         2 . The inflatable product as claimed in  claim 1 , wherein the inflatable body further comprises a second wall fused with the first auxiliary sheet; and the first wall and the second wall do not overlap each other. 
     
     
         3 . The inflatable product as claimed in  claim 2 , wherein the first wall is substantially perpendicular to the second wall when the inflatable body is inflated to expand. 
     
     
         4 . The inflatable product as claimed in  claim 2 , wherein the supplemental layer and the first auxiliary sheet are sewn by sewing threads, the first wall and the first auxiliary sheet are fused along a first fusion line with the sewing threads disposed inner than the first fusion line, and the second wall and the first auxiliary sheet are fused along a second fusion line with the first fusion line disposed inner than the second fusion line. 
     
     
         5 . The inflatable product as claimed in  claim 1 , further comprising a second auxiliary sheet wherein the supplemental layer, the second auxiliary sheet and the first auxiliary sheet are sequentially arranged and the second auxiliary sheet physically contacts the supplemental layer and the first auxiliary sheet. 
     
     
         6 . The inflatable product as claimed in  claim 5 , wherein the supplemental layer, the second auxiliary sheet and the first auxiliary sheet are fixed together by sewing and/or gluing. 
     
     
         7 . The inflatable product as claimed in  claim 1 , further comprising a tension element connected to the inflatable body, thereby controlling expansion of the inflatable body when the inflatable body is inflated. 
     
     
         8 . The inflatable product as claimed in  claim 7 , wherein the tension element is made of fabric or plastic. 
     
     
         9 . The inflatable product as claimed in  claim 7 , further comprising a fusible element wherein the fusible element is fused with the inflatable body, and the tension element is connected to the fusible element to pull the inflatable body through the fusible element when the inflatable body is inflated. 
     
     
         10 . The inflatable product as claimed in  claim 9 , wherein the tension element is connected to the fusible element by sewing or gluing. 
     
     
         11 . The inflatable product as claimed in  claim 7 , wherein the tension element is connected to the inflatable body by fusion. 
     
     
         12 . The inflatable product as claimed in  claim 1 , wherein:
 the inflatable body further comprises a second wall and a third wall;   the third wall comprises an edge portion fused with the first auxiliary sheet, and another edge portion fused with the second wall.   
     
     
         13 . The inflatable product as claimed in  claim 1 , wherein:
 the inflatable body further comprises a second wall;   the second wall comprises a first part disposed opposite to the first wall, and a second part integrally formed with the first part as a continuous piece;   the first auxiliary sheet comprises a third part fused with the first wall, and a fourth part integrally formed with the third part as a continuous piece;   the second part of the second wall is fused with the fourth part of the first auxiliary sheet;   a thickness of the inflatable body is formed by the fourth part of the first auxiliary sheet and the second part of the second wall when the inflatable body is inflated to expand.   
     
     
         14 . A method of producing an inflatable product comprising:
 connecting a supplemental layer to an auxiliary structure by sewing threads;   fusing a first wall with the auxiliary structure along a first fusion line, with the sewing threads disposed inner than the first fusion line;   fusing a second wall with the auxiliary structure along a second fusion line, with the first fusion line disposed inner than the second fusion line.
