Air bed

Abstract

An air bed comprises a mattress which is inflatable and collapsible and a lot of supporting pieces provided therein. The supporting pieces are spaced equidistantly and arranged in a plurality of transverse and longitudinal lines. The upper and the lower ends of the supporting pieces are combined respectively with the upper and the lower sides of the mattress. The mattress is provided with a valve for aerating and discharging air. Combining the supporting pieces with the mattress can save material and reduce cost of production, and the air bed after aeration can give appropriate elasticity for comfortable feeling of a person lying thereon.

1 . An air bed comprising: 
 a mattress with a flat and elongate body which is inflatable and collapsible and is provided with a valve for aerating and discharging air;    a lot of supporting pieces installed inside the said mattress and arranged in an array with a plurality of transverse and longitudinal lines, said supporting pieces in each of said lines are spaced equidistantly, the upper and the lower ends of each of said supporting pieces are of equal length and are respectively combined with the upper and the lower sides of the said mattress, the middle portion of the said supporting pieces is recessed inwardly;    whereby combining the said supporting pieces with the said mattress and aerating, the surfaces around the said upper and the said lower sides of the said supporting pieces are so fully inflated that give appropriate elasticity for a person lying on the said air bed.    
   
   
       2 . The air bed according to the  claim 1 , wherein the upper and the lower ends of the said supporting pieces are combined respectively with the upper and the lower sides of the said mattress by a high frequency irradiation.  
   
   
       3 . The air bed according to the  claim 1 , wherein the number of the said supporting pieces in each said longitudinal lines are equal and the said transverse lines are mutually parallel too.
