Inflatable mat having blocking structure

Abstract

An inflatable mat includes a top covering layer, a bottom covering layer, and a plurality of strip-shaped connecting members connected between the top covering layer and the bottom covering layer. The peripheries of the top covering layer and the bottom covering layer are joined and closed. The connecting members are thin and light. A plurality of blocking units are disposed between the top covering layer and the bottom covering layer, so that a plurality of spaced spaces are formed among the top covering layer, the blocking units and the bottom covering layer, so as to block air convection and temperature radiation.

What is claimed is: 
     
         1 . An inflatable mat having a blocking structure, comprising:
 a top covering layer,   a bottom covering layer, laminated below the top covering layer, peripheries of the top covering layer and the bottom covering layer being joined and closed;   one or more than two connecting members, connected between the top covering layer and the bottom covering layer;   one or more than two blocking units, disposed between the top covering layer and the bottom covering layer to form a plurality of spaced spaces for blocking air convection and temperature radiation.   
     
     
         2 . The inflatable mat as claimed in  claim 1 , wherein the blocking unit includes a first blocking unit, the first blocking unit includes one layer or more than two laminated layers of a polyester film material (Mylar®), and a predetermined distance is defined between the layers. 
     
     
         3 . The inflatable mat as claimed in  claim 2 , wherein the first blocking unit includes one layer or more than two laminated layers of a non-woven fabric, and a predetermined distance is defined between the layers. 
     
     
         4 . The inflatable mat as claimed in  claim 3 , wherein the blocking unit includes a second blocking unit. 
     
     
         5 . The inflatable mat as claimed in  claim 4 , wherein the second blocking unit is made of one layer or more than two layers of a thermoplastic polyurethane (TPU) material. 
     
     
         6 . The inflatable mat as claimed in  claim 5 , wherein the second blocking unit is laminated below the first blocking unit. 
     
     
         7 . The inflatable mat as claimed in  claim 6 , wherein a predetermined distance is defined between the second blocking unit and the first blocking unit. 
     
     
         8 . The inflatable mat as claimed in  claim 7 , wherein the blocking unit includes a third blocking unit, the third blocking unit includes one layer or more than two laminated layers of a polyester film material (Mylar®), and a predetermined distance is defined between the layers.
