Inflatable bed

Abstract

An inflatable bed is provided, which includes an inflatable chamber surrounded by a top sheet, a bottom sheet, and a surrounding sheet; and a plurality of internal tensioning members connecting the top sheet and the bottom sheet and provided in the inflatable chamber. The inflatable bed further includes a non-closed annular upper diagonal tensioning beam and a lower diagonal tensioning beam provided in the inflatable chamber. An upper end of the upper diagonal tensioning beam is connected to the top sheet, and a lower end of the upper diagonal tensioning beam is connected to the surrounding sheet, thereby forming an upper edge frame. An upper end of the lower diagonal tensioning beam is connected to the surrounding sheet, and a lower end of the lower diagonal tensioning beam is connected to the bottom sheet, thereby forming a lower edge frame.

What is claimed is: 
     
         1 . An inflatable bed, comprising an inflatable chamber surrounded by a top sheet, a bottom sheet, and a surrounding sheet; and a plurality of internal tensioning members that are connected to the top sheet and the bottom sheet and provided in the inflatable chamber;
 wherein the inflatable bed further comprises a non-closed annular upper diagonal tensioning beam and a lower diagonal tensioning beam that are provided in the inflatable chamber;   an upper end of the upper diagonal tensioning beam is connected to the top sheet and a lower end of the upper diagonal tensioning beam is connected to the surrounding sheet, thereby forming an upper edge frame;   an upper end of the lower diagonal tensioning beam is connected to the surrounding sheet and a lower end of the lower diagonal tensioning beam is connected to the bottom sheet, thereby forming a lower edge frame.   
     
     
         2 . The inflatable bed according to  claim 1 , wherein the upper diagonal tensioning beam and the lower diagonal tensioning beam are both provided with gaps,
 the upper edge frame and the lower edge frame are communicated with gas in the inflatable chamber through the gaps.   
     
     
         3 . The inflatable bed according to  claim 2 , wherein both the upper diagonal tensioning beam and the lower diagonal tensioning beam are single sheet and in a bent circular structure. 
     
     
         4 . The inflatable bed according to  claim 3 , wherein the upper diagonal tensioning beam is connected to the top sheet via a first weld seam, the upper diagonal tensioning beam is connected to the surrounding sheet via a second weld seam, the lower diagonal tensioning beam is connected to the surrounding sheet via a third weld seam, and the lower diagonal tensioning beam is connected to the bottom sheet via a fourth weld seam;
 wherein the first weld seam, the second weld seam, the third weld seam, and the fourth weld seam are a non-closed circular shape.   
     
     
         5 . The inflatable bed according to  claim 4 , wherein the second weld seam and the third weld seam are arranged in parallel and spaced apart. 
     
     
         6 . The inflatable bed according to  claim 1 , wherein the internal tensioning member is an internal tensioning beam. 
     
     
         7 . The inflatable bed according to  claim 6 , wherein the internal tensioning beam is at least one of a straight tensioning beam, a wavy tensioning beam, and a coil tensioning beam. 
     
     
         8 . The inflatable bed according to  claim 1 , wherein the internal tensioning member comprises a first connector, a rope-like tensioning beam, and a second connector;
 wherein the first connector is provided on an inner surface of the top sheet, the second connector is provided on an inner surface of the bottom sheet;   the first connector and the second connector are connected by the rope-like tensioning beam.   
     
     
         9 . The inflatable bed according to  claim 8 , wherein two ends of the rope-like tensioning beam are respectively detachably connected to the first connector and the second connector. 
     
     
         10 . The inflatable bed according to  claim 1 , wherein the surrounding sheet is provided with an air valve or an electric air pump.
