Inflatable product

Abstract

An inflatable product includes an inflatable body and a tensioning structure disposed in and connected to the inflatable body, for controlling expansion of the inflatable body when the inflatable body is inflated. The tensioning structure comprises a plastic portion connected to the inflatable body by fusion or gluing, and a fabric portion connected to the plastic portion by sewing or gluing.

What is claimed is: 
     
         1 . An inflatable product comprising:
 an inflatable body;   a tensioning structure disposed in and connected to the inflatable body, for controlling expansion of the inflatable body when the inflatable body is inflated;   wherein the tensioning structure comprises a plastic portion connected to the inflatable body by fusion or gluing, and a fabric portion connected to the plastic portion by sewing or gluing.   
     
     
         2 . The inflatable product as claimed in  claim 1 , wherein the plastic portion is connected to the inflatable body along a line, and the line has a closed shape. 
     
     
         3 . The inflatable product as claimed in  claim 2 , wherein the plastic portion comprises a first strap, a second strap disposed in parallel to the first strap, a third strap disposed perpendicular to the first strap and the second strap, and a fourth strap disposed in parallel to the third strap. 
     
     
         4 . The inflatable product as claimed in  claim 3 , wherein the first strap is longer than the third strap, the second strap and the first strap are substantially equal in length, and the fourth strap and the third strap are substantially equal in length. 
     
     
         5 . The inflatable product as claimed in  claim 3 , wherein the third strap adjoins the first strap and/or the second strap, and the fourth strap adjoins the first strap and/or the second strap. 
     
     
         6 . The inflatable product as claimed in  claim 3 , wherein the first strap, the second strap, the third strap and the fourth strap are spaced from each other. 
     
     
         7 . The inflatable product as claimed in  claim 2 , wherein the plastic portion is a sheet. 
     
     
         8 . The inflatable product as claimed in  claim 1 , wherein:
 the plastic portion comprises a first strap, and a second strap disposed in parallel to the first strap;   the first strap is connected to the inflatable body along a first line;   the second strap is connected to the inflatable body along a second line.   
     
     
         9 . The inflatable product as claimed in  claim 8 , wherein the first line and the second line are similar in shape and are disposed in a symmetrical arrangement. 
     
     
         10 . The inflatable product as claimed in  claim 8 , wherein the first line and the second line are identical in shape. 
     
     
         11 . The inflatable product as claimed in  claim 8 , wherein the first line and the second line are curved at ends thereof. 
     
     
         12 . The inflatable product as claimed in  claim 1 , wherein the fabric portion is a sheet. 
     
     
         13 . The inflatable product as claimed in  claim 1 , wherein the fabric portion comprises a plurality of straps disposed in parallel. 
     
     
         14 . An inflatable product comprising:
 an inflatable body;   a tensioning structure disposed in and connected to the inflatable body, for controlling expansion of the inflatable body when the inflatable body is inflated;   wherein the tensioning structure comprises a first plastic portion, a second plastic portion disposed opposite to the first plastic portion, a first fabric portion, and a second fabric portion disposed opposite to the first fabric portion;   wherein the first plastic portion and the second plastic portion are connected to the inflatable body by fusion or gluing, and the first fabric portion and the second fabric portion are connected to the first plastic portion and the second plastic portion by sewing or gluing.   
     
     
         15 . The inflatable product as claimed in  claim 14 , wherein the first plastic portion comprises a first strap connected to the first fabric portion by sewing or gluing, and a second strap disposed in parallel to the first strap and connected to the second fabric portion by sewing or gluing.
