Airbed utilizing extruded coils

Abstract

An extruded, seamless and weld-free, loop of flexible material for use as a coil in an airbed. The extruded coil provides more strength and no weak points for coils, and thus a more stable, durable, airbed. In addition, the process of using an extruded coil allows for less manufacturing deviation, and thus a more consistently durable airbed. The extruded coils may be textured inside and out to allow for ease of assembly, and to keep the coils from sticking during inflation and deflation of the product.

1 . An airbed, comprising: 
 an upper wall;    a lower wall; and    at least one coil connected between the upper wall and the lower wall, said at Least one coil comprising an extruded, weld-free, loop of flexible material.    
   
   
       2 . The airbed of  claim 1 , wherein the coil is seamless.  
   
   
       3 . The airbed of  claim 1 , wherein the coil is connected to the upper and lower walls by ellipse-like welds.  
   
   
       4 . The airbed of  claim 1 , said at least one coil comprises texture inside and out.  
   
   
       5 . The airbed of  claim 4 , wherein said at least one coil comprises polyvinylchloride.  
   
   
       6 . The airbed of  claim 1 , wherein said at least one coil comprises polyvinylchloride.  
   
   
       7 . A method of forming an airbed, comprising: 
 extruding at least tone coil, said at least one coil comprising a weld-free, loop of flexible material; and    connecting said at least one coil to an upper wall and a lower wall of the airbed.    
   
   
       8 . The method of  claim 7 , wherein connecting comprises welding said at least one coil to he upper and lower walls.  
   
   
       9 . The method of  claim 7 , wherein connecting comprises welding said at least one coil to the upper and lower walls using ellipse-like welds.  
   
   
       10 . The method of  claim 7 , wherein said at least one coil is seamless.  
   
   
       11 . A method of forming an airbed, comprising: 
 obtaining at least one coil, said at least one coil comprising an extruded, weld.-free, loop of flexible material; and    connecting said at least one coil to an upper wall and a lower wall of the airbed.    
   
   
       12 . The method of  claim 11 , wherein connecting comprises welding said at least one coil to the upper and lower walls.  
   
   
       13 . The method of  claim 11 , wherein connecting comprises welding said at least one coil to the upper and lower walls using ellipse-like welds.  
   
   
       14 . The method of  claim 11 , wherein said at least one coil is seamless.
