Sleeping device

Abstract

An inflatable mattress is provided that has a method of retaining a sleeping bag on top of it. Retaining a sleeping bag on top is achieved by using a coverlet. The coverlet is connected to the top of the inflatable mattress by suitable fasteners. The pocket formed between the coverlet and mattress portion is where a sleeping bag is inserted. An air fill mechanism is provided that is easily accessible from the outside of the mattress. An integral protective flap is also provided. The flap encases the mattress when in a rolled-up configuration and protects it during storage and transport. The device operates as one self-contained unit.

What is claimed is:  
     
         1 . A sleeping device comprising: 
 a mattress,    and a coverlet, said coverlet being fastened to said mattress,    whereby said coverlet and said mattress form a pocket into which a sleeping bag is inserted.    
     
     
         2 . The sleeping device of  claim 1  wherein said coverlet is a continuous sheet of fabric.  
     
     
         3 . The sleeping device of  claim 1  wherein said coverlet is netting material.  
     
     
         4 . The sleeping device of  claim 1  wherein said coverlet is a series of straps.  
     
     
         5 . The sleeping device of  claim 1  wherein said coverlet is fastened to said mattress by slide fasteners.  
     
     
         6 . The sleeping device of  claim 1  wherein said coverlet is fastened to said mattress by snaps.  
     
     
         7 . The sleeping device of  claim 1  wherein said coverlet is fastened to said mattress by buttons.  
     
     
         8 . The sleeping device of  claim 1  further including an integrated protective flap, said integrated protective flap is a pouch that encases said inflatable mattress, said coverlet, and said air fill mechanism during transport and storage.  
     
     
         9 . A sleeping device comprising: 
 an inflatable mattress, wherein said inflatable mattress has an inflatable bladder and outer covering of protective fabric material,    a coverlet, said coverlet being fastened to said inflatable mattress, whereby fastening said inflatable mattress to said coverlet forms a pocket into which a sleeping bag is inserted,    an air fill mechanism, wherein said air fill mechanism is a valve and a tube connected to said inflatable bladder and is accessible on the outside of said sleeping device,    and an integrated protective flap, wherein said integrated protective flap is a pouch that encases said inflatable mattress, said coverlet, and said air fill mechanism during transport and storage.    
     
     
         10 . The sleeping device of  claim 9  wherein said inflatable bladder is comprised of: 
 a layer of flexible gas impermeable material containing a plurality of spaced protrusions,  
 a flat layer of gas impermeable material of similar size and shape sealed to said layer at its periphery and at various locations between said spaced protrusions to form an inflatable assembly, wherein said spaced protrusions extend away from said flat layer and said spaced protrusions are in fluid communication with each other,  
 a port for inflation and deflation in said inflatable assembly for the attachment of an inflationary means,  
 and an additional flat layer of similar size and shape connected to the tips of all said spaced protrusions of said inflatable assembly,  
 whereby said spaced protrusions are laterally stabilized by their connection to said additional flat layer, are spaced to minimize the volume of air needed to fill said inflatable assembly, and support a load on the structure when inflated.  
 
     
     
         11 . The sleeping device of  claim 9  wherein said inflatable bladder is a self inflating bladder containing expandable foam surrounded by a gas impermeable shell.  
     
     
         12 . A sleeping device comprising: 
 a foam mattress, said foam mattress having a foam interior surrounded by an outer layer of protective fabric,    a coverlet, said coverlet being fastened to said foam mattress, whereby fastening said foam mattress to said coverlet forms a pocket into which a sleeping bag is inserted,    and an integral protective flap, wherein said integrated protective flap is a pouch that encases said inflatable mattress, said coverlet, and said air fill mechanism during transport and storage.
