Sleeping bag with integrated air mattress

Abstract

A sleeping bag with an integrated air mattress includes outer and inner shells, an inflatable tube grid, insulation, and means for selectively inflating the tube grid. Both the outer and inner shells have inner and outer surfaces, and each defines an opening. The inner shell's outer surfaces are positioned adjacent the outer shell's inner surfaces, and the inner shell's opening is aligned adjacent the outer shell's opening. The tube grid defines a plurality of grid cavities and is sandwiched between the outer and inner shells. Insulation is positioned in the grid cavities and sandwiched between the outer and inner shells. When the tube grid is inflated, the user may enter the sleeping bag through the inner shell's opening. To pack the sleeping bag, the tube grid is deflated, causing the tube grid and insulation to shift from an expanded to a compressed configuration, taking up a minimal amount of space.

1 . A sleeping bag with an integrated air mattress, comprising: 
 an outer shell having top and bottom portions and opposed first and second ends with said first end defining an opening, said top and bottom portions each having respective inner and outer surfaces;    an inner sheet situated in said outer shell adjacent said inner surface of said outer shell bottom portion;    an inflatable tube grid sandwiched between said inner surface of said outer shell bottom portion and said inner sheet, said inflatable tube grid defining a plurality of grid cavities; and    means for selectively imparting a stream of air to said inflatable tube grid for inflating said inflatable tube grid.    
   
   
       2 . The sleeping bag as in  claim 1  further comprising insulation positioned in said respective grid cavities.  
   
   
       3 . The sleeping bag as in  claim 2  further comprising bottom insulation sandwiched between said inner surface of said outer shell bottom portion and said inner sheet.  
   
   
       4 . The sleeping bag as in  claim 1  further comprising insulation sandwiched between said inner surface of said outer shell bottom portion and said inner sheet.  
   
   
       5 . The sleeping bag as in  claim 1  wherein said means for selectively imparting a stream of air to said inflatable tube grid for inflating said inflatable tube grid is a hand pump operatively connected to said inflatable tube grid.  
   
   
       6 . The sleeping bag as in  claim 1  wherein said means for selectively imparting a stream of air to said inflatable tube grid for inflating said inflatable tube grid is a foot pump operatively connected to said inflatable tube grid.  
   
   
       7 . The sleeping bag as in  claim 1  wherein said means for selectively imparting a stream of air to said inflatable tube grid for inflating said inflatable tube grid is a compressor operatively connected to said inflatable tube grid.  
   
   
       8 . The sleeping bag as in  claim 1  further comprising means for selectively releasing air from said inflatable tube grid for deflating said inflatable tube grid.  
   
   
       9 . A sleeping bag with an integrated air mattress, comprising: 
 an outer shell having opposed top and bottom portions and opposed first and second ends with said first end of said outer shell defining an opening, said top and bottom portions of said outer shell each having respective inner and outer surfaces;    an inner shell having opposed top and bottom portions and opposed first and second ends with said first end of said inner shell defining an opening, said top and bottom portions of said inner shell each having respective inner and outer surfaces, said outer surfaces of said top and bottom portions of said inner shell being positioned adjacent said inner surfaces of said top and bottom portions of said outer shell, said opening defined by said inner shell registering with said opening defined by said outer shell;    an inflatable tube grid sandwiched between said inner surface of said outer shell bottom portion and said outer surface of said inner shell bottom portion, said inflatable tube grid defining a plurality of grid cavities; and    means for selectively imparting a stream of air to said inflatable tube grid for inflating said inflatable tube grid.    
   
   
       10 . The sleeping bag as in  claim 9  further comprising insulation positioned in said respective grid cavities.  
   
   
       11 . The sleeping bag as in  claim 10  further comprising bottom insulation sandwiched between said inner surface of said outer shell bottom portion and said outer surface of said inner shell bottom portion.  
   
   
       12 . The sleeping bag as in  claim 11  further comprising top insulation sandwiched between said inner surface of said outer shell top portion and said outer surface of said inner shell top portion.  
   
   
       13 . The sleeping bag as in  claim 9  further comprising insulation sandwiched between said inner surface of said outer shell bottom portion and said outer surface of said inner shell bottom portion.  
   
   
       14 . The sleeping bag as in  claim 9  further comprising insulation sandwiched between said inner surface of said outer shell top portion and said outer surface of said inner shell top portion.  
   
   
       15 . The sleeping bag as in  claim 9  wherein said means for selectively imparting a stream of air to said inflatable tube grid for inflating said inflatable tube grid is a hand pump operatively connected to said inflatable tube grid.  
   
   
       16 . The sleeping bag as in  claim 9  wherein said means for selectively imparting a stream of air to said inflatable tube grid for inflating said inflatable tube grid is a foot pump operatively connected to said inflatable tube grid.  
   
   
       17 . The sleeping bag as in  claim 9  wherein said means for selectively imparting a stream of air to said inflatable tube grid for inflating said inflatable tube grid is a compressor operatively connected to said inflatable tube grid.  
   
   
       18 . The sleeping bag as in  claim 9  further comprising an air escape valve for selectively releasing air from said inflatable tube grid for deflating said inflatable tube grid.  
   
   
       19 . An air mattress comprising: 
 an outer shell having top and bottom portions; and    an inflatable tube grid sandwiched between said outer shell top and bottom portions, said inflatable tube grid defining a plurality of grid cavities.    
   
   
       20 . The air mattress as in  claim 19  further comprising insulation positioned in said respective grid cavities.
